Overview Of Cooling System Engineering Essay

In order to cut downing fuel ingestion and run into the emanation criterions, many betterments has been made. The illustrations of the betterments are combustion schemes, fuel injection system, exhaust emanation and fuel quality [ 1 ] . There are four possible beginnings of atmospheric pollution from the car. Without emanation controls, a carburettor and fuel armored combat vehicle emits bluess, the crankcase emits blowby gases and the tailpipe emits exhaust gases that contain pollutants. The chief regulated pollutant in engine fumes are nitrogen oxides ( NOx ) , C monoxide ( CO ) , unburned hydrocarbon ( HC ) and smoke [ 2 ] . These air pollutants are harmful to human existences every bit good as workss and animate beings. The jurisprudence now requires automotive makers to put in emanation controls. Car that gives away inordinate sum of air pollutants may non be allowed on the streets someday. Stronger Torahs restricting automotive air pollution and compulsory review and care has been proposed. These Torahs are portion of the authorities policy that autos must lend every bit small as possible to the job of air pollution. Each auto already have three major systems for commanding pollutants from these beginnings that is positive crankcase airing ( PVC ) , evaporative emanation control and exhaust emanation control. But in this survey we want to concentrate more on engine chilling system and its effects to the emanation decrease, fuel ingestion and engine public presentation. Now, we will through about the constituents of engine chilling system and its maps. Engine chilling system is a system that responsible for chilling the engine by let go ofing heat through the chilling fives so that the auto & A ; acirc ; ˆâ„ ¢s engine is non excessively hot or non excessively cold. This system helps to convey the engine up at to normal runing temperatures every bit rapidly as possible and maintain the operating temperature for efficient map of the auto engine. It is really of import to maintain the engine at its most operating temperature at all velocities and runing conditions. Burning fuel in the engine produces heat. Some of the heat must be taken away before it amendss the engine parts. This is one of the occupations that performed by the chilling system. If the engine temperature is excessively low, fuel ingestion will lift and if the temperature is excessively hot for excessively long, the engine will overheat.1.2 TYPES OF COOLING SYSTEMThere are two types of auto chilling system which is the air chilling system and liquid chilling sys tem. Air chilling system is a system that uses air as a chilling agent. It is normally used in individual cylinder engines such as bikes while liquid chilling system is known as the radiator system. It a system that uses liquid as a chilling agent and is used in a multi-cylinder engine such as autos and trucks. Radiator is the important constituents in the auto chilling system. It ensures the engine is non overheating. Figure 1.1: Cooling System Components [ 12 ]1.3 COMPONENTS OF COOLING SYSTEM1.3.1 WATER JACKETFor operation of the chilling systems, it uses five basic parts or constituents to make the occupation in commanding the engine temperature that is H2O jackets, H2O pump, thermoregulator, radiator and fan. Water jackets are unfastened infinites between the cylinder walls and the outside shell of the block and caput. Coolant from the H2O pump flows foremost through the block H2O jackets. Then, the coolant flows up through the cylinder caput H2O jackets and back to the radiator.1.3.2 WATER PUMPWater pump normally known as impeller pumps. It is attached to the forepart of the engine and are driven by a belt from crankshaft block. The pump circulates every bit much as 28 390 L of coolant an hr. As the impeller rotates, the curving blades draw coolant from the underside of the radiator. It forces the coolant from the pump mercantile establishment to the H2O jackets. The impeller shaft is supporte d on certain bearings which ne'er need lubrication. The seals prevent the coolant from leaking past the bearings.1.3.3 RadiatorRadiator is a heat money changer that removes heat from engine coolant that go throughing through it. The heat transportation from the hot coolant to the ice chest outside air. It has three chief parts that is radiator nucleus, recess and mercantile establishment armored combat vehicles. The nucleus consists of set of tubings and set of fives that attached to the tubings. Figure 1.2: Coolant Flow Inside Engine Cooling System [ 12 ] C: UsersFaisal Mamat.FaisalMamat-PCDesktopCapture.PNG1.3.4 ThermostatFor thermoregulator, it is a heat operated valve that regulates the coolant temperatures. It does this by commanding the coolant flow from the engine to the radiator. The thermoregulator is in the coolant transition between the cylinder caput and the radiator. The valve in thermostat stay unfastened and close as coolant temperature alterations. Equally long as the coolant temperature is below the thermoregulator set point, the thermoregulator remains closed. Once the temperature arrives at the set point, the thermoregulator starts to open, directing heated coolant through the radiator. The radiator so cools the het engine coolant and the H2O pump forces the coolant back through the engine. The transition to the radiator is closed when the engine is cold so the engine can warms up more rapidly. Engine heat corsets in the engine alternatively of being carrie d to the radiator. Figure 1.3: Closed Position of Thermostat [ 12 ] Figure 1.4: Open Position of Thermostat [ 12 ]1.3.5 ELECTRIC FANAn electric fan is turned on by thermostatic switch merely when needed. For illustration, it turns on when the coolant temperature reach 93 & A ; Acirc ; & A ; deg ; C and turn off back the fan if the coolant drops below this temperature. But on vehicles with air conditioning, turning on the air conditioner bypass the thermostatic switch. The fans run all the clip when air conditioner is on. The fan is controlled by electronic control faculty ( ECM ) in many vehicles with an electronic engine control system.1.4 PROPERTIES OF COOLANT1.4.1 TAP WATERTap H2O is drinkable H2O supplied to a pat inside the family or workplace. The application of engineerings involved in supplying clean H2O to places, concerns and public edifices is a major subfield of healthful technology. Specific chemical compounds are frequently added to tap H2O during the intervention procedure to set the pH or take contaminations, every bit good as Cl to kill biological toxins. The usage of tap H2O adversely affect the auto chilling system. Tap H2O contains Mg and Ca ions that will organize the xanthous precipitate ( rust ) when the H2O becomes hot. The xanthous precipitate will be attached to the auto engine after long clip period and this will cut down the soaking up of heat from the engine. If this rust become denser, it can interfere the transition of chilling liquid in the auto chilling system.1.4.2 ETHYLENE GLYCOL ( EG )Ethylene ethanediol is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure signifier, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene ethanediol is toxic, and consumption can ensue in decease. Ethylene ethanediol is produced from ethene via the intermediate ethene oxide. The major usage of ethene ethanediol is as a medium for convective heat transportation. For illustration, cars and liquid cool ed computing machines. Pure ethene ethanediol has a specific heat capacity about one half that of H2O. So, while supplying freezing protection and an increased boiling point, ethylene ethanediol lowers the specific heat capacity of H2O mixtures relative to pure H2O. A 50/50 mix by mass has a specific heat capacity of about 0.75 BTU/lb F, therefore necessitating increased flow rates in same system comparings with H2O.1.5 FuelGasoline is a transparent, crude oil derived liquid that is used chiefly as a fuel in internal burning engines. It consists largely of organic compounds obtained by the fractional distillment of crude oil, enhanced with a assortment of additives. Some gasolene besides contain ethanol as an alternate fuel. A good gasolene quality should hold: Proper volatility, which determines how easy the gasolene vaporizes. Resistance to trip knock or explosion. Oxidation inhibitors, which prevent formation of gum in the fuel system. Antirust agents, which prevent rusting of metal parts in the fuel system. Detergents, which maintain aid maintain the carburettor or fuel injectors clean. Dye for designation, such as ruddy oculus which gives leaded gasolene a rust or orange coloring material.1.5.1 VOLATILITYVolatility is the easiness with which a gasolene vaporizes. Gasoline must zap rapidly after it is assorted with air in the throttle organic structure or intake manifold. Otherwise, beads of liquid gasolene enter the cylinder walls. This increases wear of the cylinder walls, Pistons and rings. Gasoline that does non zap will non fire. It leaves the cylinder in the fumes gas and pollutes the air. This wastes gasolene and reduces fuel economic system. Volatility determines how rapidly a gasolene can zap. A high volatility gasolene can zap rapidly while a low volatility gasolene vaporizes easy. Gasoline must hold the right volatility for the clime in which it is used.1.5.2 ANTIKNOCK QUALITYAntiknock is known as octane evaluation. It measure the gasolene ability to defy knock during burning. The higher the octane evaluation, the greater the engine ‘s opposition to strike hard. The knocking in your engine occurs when the air fuel mixture detonates prematurely. Since it is the gasolene vapour that ignites, the air fuel mixture must be right to fire swimmingly. Some of the jobs associated with knock are overheating of engine parts such as valves, Pistons and flicker stoppers.1.6 EmissionThen we will travel for the account about the burning in the engine and how it ensuing emanation. Automotive fuels such as gasolene are made largely of two elements that H and C. They have chemical symbols H and C. This type of fuel is hydrocarbon ( HC ) . During complete burning in the engine, these two elements unite with other component, the gas O. Oxygen, normally in the signifier of free O ( O2 ) , makes up approximately 20 per centum of the Earth atmosphere. This is the air that we breathe. During burning procedure, each atom of O will unify with two H atoms. Each C atom unites with two O atoms. Oxygen unifying with H green goodss H2O ( H2O ) . Carbon unifying with O green goodss gas C dioxide ( CO2 ) . During burning, the combustion of air fuel mixture in the engine cylinder may make 2200oC or higher. This high temperature produces force per unit area in the engine that makes it run and produces power. With perfect burning, all the H and C in gasolene would unify with the O. The fumes would incorporate merely harmless H2O and CO2. But burning is non perfect in the engine. Some of the gasolene ( HC ) does non fire. Besides, some of it merely partially burns. This produces C monoxide ( CO ) . This deficiency of O prevents the formation of C dioxide. The unburned gasolene and partially burned gasolene ( CO ) issue from the engine through the tailpipe. Once in the air, it will do atmospheric pollution. Another group of atmospheric pollutants the engine is nitrogen oxide ( NOx ) . About 80 per centum of the ambiance is gas N ( N ) . High temperatures in the burning chamber do some of the N and O to unify and organize N oxide ( NOx ) .1.7 PROBLEM STATEMENTNowadays the rate of fuel ingestion presently traveling on throughout the universe is rather dismaying. Fuel ingestion and emanation rates are off the chart. This will give negative impact to the environment and increase the pollution rate. Basically the power to travel a motor vehicle comes from the combustion of air fuel mixture in an engine. Air pollutants from vehicles comes from the merchandises of this burning procedure. With perfect burning procedure, the emanation would be H2O ( H2O ) and C dioxide ( CO2 ) . Both of these are harmless gases. But burning is non perfect in an engine. Some of the gasolene ( HC ) does non fire and some of it merely partially burns. This produces C monoxide ( CO ) and nitrogen oxide ( NOx ) . Both of these gases are air pollutants and take a breathing contaminated air is really bad for human and animate beings. Then the demand for low cost auto from client that has good public presentation with low fuel ingestion and emanation besides addition. Normally auto that has good public presentation will hold high fuel ingestion and emanation rate. In order to work out these jobs, the survey about engine chilling system and its effects towards engine public presentation, fuel ingestion and emanation decrease will be conducted. Two types of liquid chilling such as tap H2O and ethene ethanediol will be used and its temperature will be checked in order to look into the influenced to these 3 end products.1.8 OBJECTIVES OF THE RESEARCHTo analyze the consequence of engine chilling system and its constituents to the engine public presentation, fuel ingestion and emanation. To look into the influence of per centum of ethene ethanediol in the coolant and coolant temperature set point to the engine public presentation, fuel use and emanation rate.1.9 SCOPE OF THE RESEARCHThe range of this researched is chiefly about the fluctuations per centum of coolant ( ethylene ethanediol ) mixed with H2O and its temperature effects towards engine public presentation, fuel ingestion and emanation. The per centum that will be used for ethylene ethanediols are 30 % , 50 % and 70 % . For every per centum, the coolant temperature set point will be controlled utilizing two sort of thermoregulator with temperature set point 80oC and 100oC. The increasing temperature in cylinder block by increasing the coolant temperature consequences in fuel nest eggs and emanation decrease.

Then for the fuel, gasoline RON 95 will be used. Three trial will be conducted in investigate the engine public presentation, fuel ingestion and emanation rate. The trial for engine public presentation is dynamometer trial. A ergometer is a device that is used for mensurating force, minute of force ( torsion ) , and power. For illustration, the power produced by an engine, motor or other revolving premier mover can be calculated by at the same time mensurating torsion and rotational velocity ( RPM ) . For the fuel ingestion, we will carry on a fuel trial by utilizing a new armored combat vehicle provided by automotive lab. Unit of measurement to mensurate the fuel trial is in liter/km. To mensurating the emanation rate, gas analyser is used and the measuring unit is in concentration of gas which is parts per million ( ppm ) .1.10 SIGNIFICANT OF THE RESEARCHThis survey will give better apprehension and exposure about the operation in the engine chilling system and how it will effects the engine public presentation, fuel ingestion and emanation. Reducing the fuel disbursals by auto users as the rate of fuel ingestion reduced. The expected end product to cut downing the emanation will ensue in increased the air quality that is harmful to worlds. It besides will take in cut downing the air pollution rate and supply more safer environment for people. The low cost auto with good public presentation and low on fuel and emanation rate besides will be develop.2.0 LITERATURE REVIEW2.1 Cooling SYSTEM OPERATIONA immense sum of heat is generated in the internal burning engines. It is created when the air fuel mixture is ignited inside the burning chamber. The detonation that occur will do the Piston to be forced down indoors the cylinder, prying the connecting rods and turning the crankshaft. The temperatures of the metal parts around the cylinder can transcend 2500oC. To forestall the constituents such as engine oil, cylinder walls, Pistons, and valves from overheating, it is necessary to efficaciously dispose the heat. Approximately 30 % of heat in the burning procedure is lost into the ambiance through the fumes system, 35 % is converted into power to drive the vehicle and the staying 35 % lost as heat through the cylinder walls [ 9 ] . Water pump is attached at the forepart of the engine and driven by a belt from crankshaft block. The impeller rotates and the curving blades draw liquid chilling from the underside of the radiator and force it to flux through pump mercantile establishments and H2O jackets. The liquid chilling will flux through passageways in the engine block and cylinder caput. Temperature in the burning chamber can around 2500oC, so chilling around this country is critical to forestall overheat. The countries around exhaust valve are particularly important and about all infinite inside the cylinder caput around the valve that is non needed for construction filled with coolant. But when the engine is still cold, thermostat still near and the liquid chilling is circulated back to the engine. By shuting the transition through radiator when engine is cold, the engine warms up more rapidly. Engine heat corsets in the engine alternatively of being carried to the radiator. This shortens warms up clip, wastes less fuel and reduces exhaust emanations [ 3 ] . After engine already heat up, the thermoregulator keeps the engine running at a higher temperature than it would without a thermoregulator. The higher operating temperature improves engines efficiency and reduces exhaust emanations [ 3 ] .2.1.1 EFFECT OF RADIATORA radiator normally known as heat money changer. The hot coolant that flows through it will reassign the heat by the air blown through the aluminum fives by fan. Nowadays modern autos use aluminium radiators. It normally made by brazing thin aluminum fives to flattened aluminum tubings. Flow of the coolant is from recess to the mercantile establishment through many tubings that mounted in parallel agreement. These fives will carry on the heat from the coolant inside the tubings and reassign it through the air that fluxing through the radiator. [ 1 ] A type of five is inserted into the tubing called turbulator. Its map is to increases the turbulency of the fluid fluxing through the tubings. If the flowing of the fluid through the tubing is smooth, merely the fluid that touching the tubings would be cool straight. The sum of heat transferred from the fluid to the tubes depends on the difference in the temperature between the tubing and the fluid touching it. Therefore, less heat will be transferred if the fluid that is in contact with the tubing cools down rapidly. To forestall that, turbulency is created inside the tubing and all of fluid mixes together. Keeping the temperature of the fluid touching the tubing up so that more heat can be extracted and all of the fluid inside the tubing is used efficaciously.2.1.2 EFFECT OF RADIATOR FANThe map of radiator fan is to pull the air towards the radiator and helps to chill the hot coolant that fluxing through the tubings. It normally has four or more blades that spin quickly to supply s ufficient air to that would chill the engine. The fan will be mounted between the radiator and the engine so that the air can easy fluxing through the radiator. There are besides extra fan in forepart of the radiator in some autos in order to pull more cool air to the engine particularly when vehicle is non traveling fast plenty, really small cool air reaches the radiator and the engine is non cooled decently.2.1.3 EFFECT OF PRESSURE CAPThe radiator cap or besides known as force per unit area cap really increases the boiling point of your coolant by about 25oC. The cap is a force per unit area release valve and normally is set to 15 pounds per square inchs. When the coolant is placed under force per unit area, its boiling point will increase. As the engine running, the chilling system will be heated up and increase the force per unit area. The lone topographic point where the force per unit area can get away is at the force per unit area cap. Therefore, the scene of the spring on th e cap determines the maximal force per unit area in the chilling system. If the force per unit area reaches 15 pounds per square inch, it will force the valve unfastened and leting the coolant to get away from the chilling system. The flowing of the coolant is from overflow tubing to into the underside of the overflow armored combat vehicle. This sort of agreement will maintain air out of the system. After the radiator is already cools back down, a vacuity is created in the chilling system that pulls unfastened another spring loaded valve while sucking the H2O back in from the underside of the overflow armored combat vehicle to replace the H2O that was expelled.2.1.4 EFFECT OF WATER PUMPWater pumps are impeller pumps. They attached to the forepart of the engine and driven by a belt from the crankshaft block. As the impeller rotates, the curving blades draw coolant from the underside of the radiator [ 3 ] . The H2O pump merely thrust to drive the round flow of the coolant within the engine chilling system, so the recess is the point of lowest force per uni t area in the system and the issue point is the highest force per unit area. The force per unit area drops aggressively at the inlet/outlet of the H2O pump during the operational of the H2O engines and this force per unit area bead will change in proportion to the rotational velocity. Water pumps in engines are prone to cavitation and air bubbles are likely to pervade in to antifreeze and will badly cut downing the public presentation, dependability and service life of the engines [ 6 ] . Cavitation means the pits or bubbles are organizing in the liquid that have been are pumping. These pits form at the low force per unit area or suction side of the pump. For the well design engine chilling system, cavitation is less likely to take occur as the temperature of the coolant diminutions. But when the cavitation temperature is reached, the force per unit area of the H2O pumps drops suddenly and all the chilling system loses its functionality.2.1.5 EFFECT OF THERMOSTATThe chief map of the thermoregulator is to let the engine to heat up rapidly and maintain it at its efficient temperature. It control this by modulating the sum of H2O that goes through the radiator. The coolant in the chilling system starts to originate by picking up heat at the H2O jackets. In the coolant circuit, the force per unit area gradient exist and doing the hot coolant flows out from the engine to the radiator or to coolant beltway transition [ 2 ] . Once the temperatures of the coolant rises to 80oC, the thermoregulator starts to open. Different thermostat unfastened at different temperatures and leting fluid to flux through the radiator. The secret of the thermoregulator lies in the little cylinder located on the engine side of the device. Actually this cylinder is filled with wax that starts to run at temperatures 80oC ( depends on the thermoregulator ) . Then, a rod that is connected to the valve imperativeness into this wax. As the wax thaws. It will spread out and forcing the rod out o f the cylinder and opening the valve.2.2 EFFECT OF COOLANTCoolant is the mixture of antifreeze and H2O in the chilling system. The normally used antifreeze is Ethylene Glycol. This coolant will go around through the chilling system. It will take the waste heat from the engine and delivers the heat through the radiator hosiery to the radiator. It is non recommended to utilize merely H2O as a liquid chilling because it would stop dead if the temperature bead below 0oC. This would halt the circulation and the engine would overheat. As the H2O would spread out 9 % as it freezes, it would check the cylinder block and caput, split the radiator [ 3 ] . By commanding the engine chilling system in a flexible manner as comparison to the conventional chilling system, it will better the fuel ingestion rate of flicker ignition ( SI ) engines [ 11 ] . It is known from the cold start research that the coolant and inlet charge temperature are cardinal parametric quantities to cut down pollutant emanations and warrant smooth engine operation. Cold start experiment were performed with coolant temperatures of 15oC and 80oC. In the steady province operation reached after the start, the Piston surface temperature was severally 110oC and 150oC. The HC emanations were 25 % lower and the NOx emanations 7 % higher with the higher coolant temperature. It seems to bespeak that there is an influence of the coolant temperature on the emanations through the cylinder wall temperatures [ 5 ] . In the hunt for greater fuel economic system and decreased emanation end product, the engine chilling system is being targeted for farther betterments to engine public presentation through its effects on engine frictional losingss. Fuel economic system betterments from the alterations to the engine chilling system are derived chiefly from reduced engine frictional losingss with increased oil temperature by raising the engine operating temperature indirectly through the measure addition in the coolant temperature. Hydrocarbon ( HC ) and C monoxide ( CO ) end product are besides shown to diminish with the addition in operating temperature [ 7 ] . There are besides suggestion that higher cylinder block temperatures will cut down the frictional losingss with the Piston and pealing battalion and will take to cut downing fuel ingestion [ 10 ] . But the increasing of operating temperature has a negative consequence on N oxide ( NOx ) end product as the formation of NOx in the burning chamber can be extremely sensitive to temperature alterations [ 7 ] . There are some old plants in the engine chilling country focal points on to the fuel economic system benefit to IC engines through the decrease engine frictional losingss by raising the coolant temperature. As the coolant temperature additions, the cylinder block wall temperaturs besides increases and will ensue in cut downing the HC emanations [ 11 ] . It concentrates chiefly on gasolene engines where oil temperature is comparatively lower and the tailpipe emanations are HC and CO. Fuel efficiency betterments about 10 % are achieved in portion burden conditions by raising coolant temperature [ 7 ] .Methodology3.1 IntroductionIn this chapter, we will discourse about the processs and full activities to transport out in this whole undertaking. The flow chart below will depict the stairss that should be followed during this undertaking. Basically there are 3 trial that will be conducted that is dynamometer trial, fuel trial and emanation trial.3.2 FLOW CHARTPart Choice Choose the type of liquid chilling and thermoregulator that will be used. Preparation and Setup Choose the type of liquid chilling and thermoregulator that will be used. Run the experiment The experiment will be conducted to the conventional and modified chilling system. Emission Trial Fuel Trial Dynamometer Test Datas AnalysisTYPES OF METHODS3.3.1 DYNAMOMETER TrialDynamometer is really a device usage to mensurating force, minute of force ( torsion ) and power produced by an engine or motor. We can see the illustration from the power produced by an engine, motor or other revolving premier mover can be calculated by at the same time mensurating torsion and rotational velocity ( RPM ) . Nowadays dyno trial become more easy to run with the progress of the modern computing machine and bring forth more accurate consequences. A dyno that paired with the computing machine will expose the power evaluation of a given machine as a figure below. Degree centigrades: UsersFaisal Mamat.FaisalMamat-PCDesktopdynamometer-test-2.1-800Ãâ€"800.jpg Figure 3.1: Example Graph of Dynamometer Test Actually dyno trial is used for assorted applications but the most common one is automobile proving. Automobile makers will mensurate the public presentation of a auto or truck in order to market its power. Sports auto will modified their vehicles with aftermarket parts in order to accomplish higher power end product and so run the dyno trial to measure their alterations. Dyno trials can be run in a twosome of different ways which is human body and engine dyno. When running a human body dyno trial, the vehicle to be tested is driven onto the dyno platform that simulates opposition through the usage of machine-controlled wheels. For an engine dyno trial, the engine to be tested is mounted to the dyno device. These different methods produce different measurings such as brake Equus caballus power and torsion from a human body dyno and flywheel Equus caballus power and torsion from an engine dyno. Power is frequently lost through the thrust train of a vehicle so the brake measuring will typically less than the flywheel measuring. The theoretical account that will be used for ergometer testing is Dynapack 3000. The constituents of Dynapack 3000 consists of computing machine, detectors hub adapters accountant and power soaking up units. This trial is a spot from other dyno trial because of the riddance of the tyre to roller interface on a conventional roller dyno. It eliminates this variable by utilizing a hub adapter that provides a direct yoke to our power soaking up units. There will be no tyre faux pas, no turn overing opposition and no opportunity of the vehicle coming off from the dyno at high velocities. For the theory of operation. First the hubs of the vehicle are straight attached to hydraulic pumps. A variable burden can be applied with all of the possible keeping power that hydraulic possess. Figure below show that the wheels are removed from the vehicle and the variable fit hub adapters are bolted to the vehicle axle. The hub adapter is so straight attached to a hydraulic soaking up unit.

Cost Accounting Is A Process That Aims To Capture A Companys Production Accounting Essay

Cost accounting is a procedure that aims to capture a companys production, to measure the input cost of each production. Cost accounting is frequently used in the company to assist the direction with determination devising. Cost comptrollers are a good as a tool for direction in budgeting and in puting up cost control which improves the net borders of the company in future. Cost comptrollers in traditional fabrication companies would normally do usage of machines that automate certain operations. Production activity is measured in machine hours. Traditional fabrication is besides labour intensive where there are high labor costs and low operating expenses. Traditional fabrication allocates the companies ‘ indirect cost to the points produced in order of their volume, figure of units produced, direct labor hours and machine hours. The usage of machine hours implies that machine hours are cause footing of the mill operating expense, this deduction is done when merely machine hour s are used to apportion the fabricating operating expense to merchandises. Cost comptrollers in traditional fabrication companies use a individual caput pool, this method of apportioning indirect costs normally consequences in the wrong cost of informations. Merchandises with high volumes have high labor costs likewise merchandises with lower volumes would normally be understated and be ignored. Traditional fabrication companies cost comptrollers are needed to assist in the managing of costs which is normally non an easy undertaking to make, but the cost comptrollers have found a manner of pull offing them. Modern fabrication was developed to work out the complexnesss of running a immense concern. Modern fabrication companies make use computing machines and robotics ; they control the whole production/manufacturing procedure. Cost comptrollers would normally necessitate modern fabrication companies because they have an built-in flexibleness to supply particular studies and assist direction with determination doing sing cost activities undertaken. Modern fabrication houses are normally non forced to stay by the fiscal coverage demands. Modern fabrication companies would normally delegate costs to activities and merchandises based on how the costs and resources are consumed by the procedure or merchandise. Cost comptrollers are needed in the modern fabrication companies because it gives them a clearer image of cost of procedure and the profitableness of clients and merchandises. They are besides needed because it would assist them with budgeting techniques for the truth of fiscal prognosi s and besides increasing the comprehension of the directors. Cost comptrollers are needed in the modern fabrication companies because modern fabrication houses use computing machines and robotics this helps in the quick and accurate production of fiscal programs to assist the comptrollers in wise determination devising. Productivity is truly improved in modern fabrication companies because there is a wider set of related component here, which is computing machines and robotics. Absorption costing is no longer for modern auto manufacturer such as BMW discuss. Your reply should include suggestions of other bing methods that are more relevant for a modern auto manufacturer and supply your accounts. Absorption costing is absorbing all the fabrication through units produced. It absorbs all the direct labor, direct stuffs, with all the variable and fixed costs. It is By and large Accepted Accounting Principles which means it is used for external coverage. Absorption costing because it absorbs all the cost is non suited for modern fabrication houses, because with this bing pricing is lesser extent than it appears to be in the instance. Cost is calculated to make up one's mind how much net income you have made, and so the monetary value while be set. Because absorbs all the costs, that establishes the fact that it does non recognize the importance fixed costs. This makes it difficult to distinguish between fixed and variable costs. The variableness of net incomes besides causes confusion because the gross revenues and stock alteration. Absorption bing recognises the importance of fixed costs in production by including them in the production procedure. It is used to fix fiscal histories. When production remains changeless while gross revenues rise and autumn irregularly in figure this method will demo a less fluctuation in net net income. Absorption costing is non suited for the modern auto makers like BMW because it is non so utile to t he direction to do wise determinations, to be after and command that is it does non assist directors to develop the company ‘s mission and aims to be the decisive factor in carry throughing them and non set uping public presentation criterions, mensurating and describing existent public presentation and comparing them to take a disciplinary action as necessary. This truly shows that it is non suited fabricating companies like BMW because they need to utilize the cost information for good determination devising intents and budgeting. But instead modern fabrication houses like BMW need to utilize Activity Based Costing because is the method of bing that assigns costs to their activities based on the resources instead than merchandises or services. Other costs and resources are equally distributed to the merchandises and services they use. This method does non extinguish any costs ; it gives more information and takes into history how costs are consumed. This method is suited for BMW because BMW is involved process betterment and reduction costs. Activity Based Costing assigns all the single activities involved in the fabrication procedure are accurately costed, that is it makes seeable waste and non value added. Therefore doing it easier to place the cost of each procedure. It uses unit cost instead entire cost. It facilitates benchmarking which means there is a standard mention against which things can be compared and assessed. It provides a better apprehension of operating expenses and it is easy understood by everyone because since companies like BMW discloses their fiscal studies to the populace they can understand why things are the manner they are. Activity Based Costing helps with future merchandise planning because for illustration all the activities associated with BMW can be accurately determined before it is launched. This can besides assist to find the monetary value and other outgos. Question 3 Cost?Material X & A ; Y working 1 4,000 Material which can be used in another machine 6,000 Labour – Department A ( working 2 ) -Department B ( working 3 ) 12,800 3,600 Sale of machine 5,000 Alteration work 2,000 Entire 33,400 Entire = ? 33,400 + ?125, 000 = ? 158, 400 Working 1 5000 – 1000 = 4000 Working 2 Department A 200 ten 2 ten 4 ten 8 = ?12,800 Working3 Department B 150 ten 4 ten 6 = ?3,600 Working 4 = ? 33, 400 = 125, 000 = ? 158, 400 ten 10 % = ? 174, 240 The minimal monetary value that should be quoted to the new purchaser is ?174, 240 ( working 4 ) . This is because this monetary value includes all the alteration work costs. MM should accept the offer made by the new purchaser because it more than the sum willing to be paid by the first purchaser. MM should besides disregard the ?2000 sedimentation made by the original purchaser because it is a historical cost that is it is a cost that has already occurred therefore doing it an irrelevant cost.

Criminal Justice Essay Example | Topics and Well Written Essays - 500 words - 9

Criminal Justice - Essay Example Any police officer trying to abuse an individual is liable to the act of oppression and people can therefore protect themselves from this form of oppression through use of the firearm as long as the cause is justifiable. Having this right protects the people from having to tolerate abuse of any form from the police simply because of their power. People are allowed to have freedom of speech, of exercising freely and make peaceful demonstrations as a way to express their grievances. Police officers take such opportunities to abuse the people by beating them or preventing them from congregating even though the first amendment has allowed them to do so. People are even arrested for no reason and some even taken to cells without any charges or fake charges such as destruction of property or resisting arrest are crowded on the individuals. This bill of right expressed in the first amendment curtails the police abuse to peaceful demonstrators and people freely expressing them-selves in speech or in press (Skeens, 2007). Lastly is the six amendment which demands that people who have criminal charges or those arrested also have their own rights which are supposed to be explained to them by the police during arrest as a way to protect themselves from police brutality and abuse. These rights include the right to be informed of the criminal charges that have made one be arrested, there is also the right to have a counsel to assist the criminally charged person as well as the right to witnesses in court. Under the Terry Stop, police are created balance so that they can be able to carry out their work effectively to preventing and dealing with crimes. This allows them to conduct searches and seizures if there is reasonable reason or if the person is under suspicion without even requiring a warrant. The police are also mandated to stop

Critically evaluate the strengths and limitations of using customer Essay

Critically evaluate the strengths and limitations of using customer focused interactions as a basis to standardise and improve business operations - Essay Example Focusing on precision and customer service accelerates the transformation process. British Telecom chose not to rely on such systems to solve its immediate problem. British Telecom saw a dramatic expansion in the number of services offered to its customers. Additional revenues from these services and related ventures have been sufficient to justify further investments of more than five billion dollars in second-generation packet switching, terminal technology, and support systems. (Johnson and Clark, 2001, 115-120) While new business units may become the principal vehicles for growth, the existing core business can also be redefined from within. New capabilities cannot only alter how the original business is conducted, but can alter the nature of the business itself. British Telecoms business focus a decade ago was voice transmission (Fraser, Shobrys & Kruse, 2003, 10-13); today it has a much broader scope of activities and services. Not all companies choose to spawn new businesses (Johnson and Clark, 2001, 115-120). New information processing capabilities can be viewed as central to the success of a traditional business and treated as a proprietary asset to be kept closely guarded in the inner sanctum of the enterprise. Yet even in such cases, those new core competencies will drive redefinition and transformation of the traditional business from within. In this way, successful customer interaction efforts ultimately lead to business transformation. (Slack, 2001, 1100-1121) â€Å"Quality management approaches can be categorized broadly into three stages according to the evolution of management control. Management can implement control before an activity commences, while the activity occurs, or after the activity has been completed.† (Hsieh, Chang & Lu, 2000, 191–201) For example, British Telecom might have chosen to address its directory services crisis with a limited solution that automated operator database access and audio response--the type

Guidelines Assessment Research Paper Example | Topics and Well Written Essays - 1500 words

Guidelines Assessment - Research Paper Example Modern clinical practice guidelines are often evaluated using the GLIA system (GuideLine Implementability Appraisal) and the AGREE instrument (Appraisal of Guidelines for Research and Evaluation). The availability of these systems is evidence of how carefully regulated these guidelines are and how they can be particularly useful in clinical situations (Field et al., 1990). The principal steps in developing a clinical practice guideline are as follows. In the first instance, the correct information needs to be identified and this should be the most current and most relevant data available concerning the diagnosis, treatment and management of the illness in question. Information should also be gathered about the cost and risk of the above, where applicable (Davis & Taylor-Vaisey, 1997). Having put all this data in place, it is then necessary to condense the information to provide it in a format readily available to clinicians (Michie & Johnston, 2004) and condense this into a format us eable in practical situations. Then, clinicians must implement the guidelines (Davis & Taylor-Vaisey, 1997), although this has been found to be difficult in many cases (Cabana et al., 1999; Michie & Lester, 2005). Clinical practice guidelines can involve computer algorithms, and their formulation can be heavily reliant on information technology (Field et al., 1990). The purpose of the AGREE instrument is to stress that the usefulness of these clinical practice guidelines is proportional to the quality of the guidelines themselves. This means that the AGREE instrument is primarily concerned with providing a framework with which to assess these guidelines, and states that it will: Assess the quality of guidelines; Provide a methodological strategy for the development of guidelines; and Inform what information and how information ought to be reported in guidelines. (AGREE Next Steps Consortium, 2009) This is taken from the newest version of the AGREE instrument, which is currently vers ion two. As is evidenced by these statements, the AGREE instrument aims to ensure that all guidelines will beneficial to both clinicians and patients. Clinical practice guidelines should provide the very best and most recent research to clinicians so that treatment, diagnosis and management of the illness in question is of the best standard possible. The AGREE instrument also ensures that clinical practice guidelines are formulated in a methodical way, and so all clinical practice guidelines formulated using this tool will be of the same standard and format, and thus the AGREE instrument is now a reliable quality evaluation tool. The AGREE instrument separates the information it provides into domains. The first domain is known as ‘scope and purpose’, which basically ensures that the basic properties of the guideline are adequately described, such as the target audience, the health questions and the objectives. The second domain is ‘stakeholder involvement’ which suggests that the discussion of the guideline involves professionals from every available and appropriate area, and that the target audience have also been consulted also. The third domain is defined as ‘rigour of development’ and essentially aims to ensure that all the evidence has been selected in an appropriate manner and that this is described in the guideline, that the strengths and weaknesses of the evidence are recognized, and that the guideline explicitly references this evidence. It also aims to provide information on how to update the procedure when necessary. The fourth domain is ‘clarity of presentation’ and aims to ensure th

How does a study of popular culture help researchers understand how Essay

How does a study of popular culture help researchers understand how financial reporting information is valued by society - Essay Example Financial reports are then prepared to mirror the popular culture that prevails in monetary terms. Thus, ideally these reports should replicate the popular culture and should tell if that suits the well being of a country or not. Critical theory encompasses the idea of popular culture. It involves the examination and analysis of a society and its culture. Recently, Geert Hofstede’s cultural dimensions have been used to describe national or, better put, popular cultures. Hofstede’s ideas are based on a large scale research project to bridge cultural differences globally and to come up with a global popular culture! It uses data obtained from sixty-four countries. These studies identify five dimensions. These dimensions can be used to analyze how similar or different countries are. Based on these, their financial reports should mirror the popular trends that prevail and should compare the financial status of the countries in a considerable time period. The first dimension is of power distance, second one being individualism, third masculinity, fourth uncertainty avoidance and last one being long term orientation( Hofstede, Geert). Power distance index is used to measure the degree to which author ity is distributed lopsidedly within an association or an institution (and even in families). It also implies that a society’s degree of disparity is authorized by the supporters as much as by the leaders. The analysis of power distance shows significant differences amongst countries, Germany has a power distance index of 35 while Arab countries have a power index of 80. The second dimension of assessing the popular culture according to Hofstede is individualism. In this, it is compared whether the citizens prefer to look after themselves only, i.e. if they prefer individualism or if they prefer collectivism and like to help others. On the individualistic side, we find societies in which the ties between individuals are loose. Everyone takes care of himself

Explain why Simmias and Cebes are so afraid of death in the phaedo, Essay

Explain why Simmias and Cebes are so afraid of death in the phaedo, whereas Socrates is not. Does Socrates' explanation convince you, or are you, like simmias a - Essay Example Socrates unequivocally asserts that any true philosopher â€Å"will be willing to die† (6). He is convinced that a better life awaits him. Death, as the harbinger of â€Å"the greatest good† (8), is something the true philosopher desires and pursues. Death may be defined as â€Å"the separation of the soul and body† (8). The philosopher is a seeker of truth and lover of wisdom, who pursues the essence of the knowledge of existence. In this pursuit, the body, with its’ lusts, sensual pleasures and physical needs, is â€Å"only a disturbing element, hindering the soul from the acquisition of knowledge† (10). Therefore, the philosopher desires death, which will release â€Å"the soul from the chains of the body† (11) and free the soul to attain the truth. His desire for the truth will be satisfied only by the separation of the soul from the body – that is, by death – which is the purification of the soul. Death is the philosopherâ €™s means to gain wisdom, while the body is his â€Å"enemy† (11). Socrates fearlessly and eagerly anticipates death and is ready â€Å"to depart with joy† (11) from this world. Cebes and Simmias acknowledge the truth of Socrates’ word, but continue to fear death, as they are afraid that the soul â€Å"may be destroyed and perish† (12) when she leaves the body, â€Å"vanishing into nothingness† after death. Socrates allays their fears by convincing them of the immortality of the soul. The accepted belief that â€Å"the living spring from the dead† (15) presupposes the prior existence of the soul, in another world, before it assumes human form. As recollection is an essential part of knowledge, this recollection is obviously gained by the intelligent souls’ existence in another place. The rebirth of the soul is proof of the souls’ immortality, as â€Å"everything living is born of the dead† (19). Once it is accepted that the soul is invisible,

Canadian Identity Essay Example | Topics and Well Written Essays - 1000 words

Canadian Identity - Essay Example The first step toward solving the problem will be recognizing the identity issue as a national problem. The government and the Canadians should then search for a common solution to the problem. In this paper, I will analyse the issue of Canadian identity from both perspectives. Regionalism is a dominant factor in Canadian social and political framework. As a political ideology, the Canadian regionalism is based on the dominance of one region over the others in national affairs. Regionalism is the main factor that has prevented Canadians from realizing their national identity (Charles 67). Firstly, regionalism has introduced divisions among Canadian citizens. It would be difficult to realize or define a true national identity on a country that is divided between social classes and generation gap. Canadian identity exists and it is responsible for our national prosperity that is based on our regionalism. Canada is divided into six basic regions that are based on geographical and social economic factors in the country. Regionalism is vital for Canadian identity. Regionalism provides a basis for national unity, which is instrumental in defining Canadian identity. ... However, Canada has been experiencing increasing numbers of immigrants from other countries (Charles 67). The existence of people from different cultures has made it impossible to define Canadian culture. Culture is a significant in defining the identity of a country. Thus, Canadians lack a common culture that they can identify themselves with or that associate them with the country. Currently Canada has become the leading country in social diversity. The country is home for people from all over the world including the Americans. As Canadian, we are a multicultural society that is not divided along ethnicity or any racial structures. The intercultural cohesion that exists among Canadians defines them as Canada citizens and people of the modern world (Mathews 98). Lack of a dominant culture or social group in the Canadian society promote national unity and freedom that defines the life of the Canadians and hence their national identity. Canada has a widening generation gap that adds c ontroversy to the issue of the Canadian identity. Since the arrival of the European immigrants, Canadians have been loosening their attachment with their European origin. There has been a continuously increasing variation in societal values across different generations. The association of Canadian citizens with their European countries of origin has been reducing constantly. The first generation of immigrants is completely different from the current generation of Canadian citizens. This trend is increasing constantly resulting into a wide generation gap. This factor is responsible for the lost Canadian identity. For instance how can we define where we are going if we do not acknowledge where we came from. It is a fact that Canadians originated from Europe and

Rap music often carries important messages Essay

Rap music often carries important messages - Essay Example The song also mentions of suffering of children caught in between wars, high youth mortality, government and media deception and greed. Another popular rap song is "Runaway Love" by Ludacris featuring Mary J. Blige. The song is about the plight of young girls of age 9, 10 and 11. One is defiled by her mother’s prostitution client, the other loses her only friend in a shot out and the last one get pregnant at 11. These girls opt to run away from home which they compare with hell. This song end by giving encouragement to the girls that they are not alone.

Blige brings out the plight of the girl child living in low income areas. Therefore, rap songs should not be generally judged as upholding criminality since they often carry important

Love at First Sight Essay Example for Free

Love at First Sight Essay One of the great questions surrounding social psychologists and everyday people by extension is whether or two individuals can fall in love at first sight. This would imply that the non-verbal communication between the two in that moment was as strong and passionate enough to constitute love before having gotten to even speak to the other. To fall in love is to have strong feelings of passion and attachment to another individual. Measuring what constitutes full love is unclear and debatable within circles, but generally agreed to be a very strong feeling that is created. Love at first sight can be described as a signal of the strongly grounded love that may be to come, but ultimately exists as a very strong first impression that cannot be predetermined to sustain itself as genuine love. There are many cues and ways in which two lovers may first lay eyes on each other that can generate such strong feelings similar to love. When the eyes meet and cannot be taken off of two individuals, this is certainly a sign that the two are at good odds of working out together. When there is a mutual astonishment of the other individual as shown in these signs and other signs, it can also create the impression that a man and a woman will go hand in hand when the very first impression is so strong and mutual. However, this is only a jump start. When two people are mutually taken aback by each other at first sight, this is a very positive sign as far as the relationship goes. First impressions are huge, but this does not mean there is any predetermined ways of knowing this sensation of love will sustain itself in way that can universally be accepted as true love. Two people may quickly find that they are not as compatible as they would have liked to have believed or were drawn into believing. Through further interaction, they learn far more about each other and any kind of sustainable love is dependent on these future interactions and feelings remaining as first presented. Many people would like to believe in love at first sight, and it makes sense why people who have had these feelings at first sight have on to carry long loved relationships. Whether or not one wants to call it love at first, the experience that one may interpret is still a powerful predictor of a more likely outcome of true love. It is true that our intuition and the hunches we get can sometimes lead us to truth in our lives. In the case of love, it is a bit trickier because the desire for love along with common lust and the seemingly meaningful non-verbal cues can easily create the sensation of love at first sight. Love is far too complicated to be treated and always assuming to be genuine and true, and never a sensation motivated by desires and perceptions within our often confused brains. However, there is no doubt that instances have occurred in which two believed they experienced love at first sight, but that love sensation simply did not sustain itself in the end. Compare these stories to the one of people who it has worked out for, and one may find that the stories of the initial feeling of love at first sight are identical. Moreover, there is of course there is the potential for one?s own judgment and intuition at first sight to be accurate about loving another, but love is ultimately created by our minds and is not determined by the other. For that reason, there is not enough certainty in the universe and too many inconsistencies to prove a consistent trend in true love at first sight.

Offshoring Paper Essay Example for Free

Offshoring Paper Essay This article talks about a trend that started as far back as the 1980’s when companies began sending many jobs abroad mainly because of cheap labor. However, that trend is quickly changing. Companies are discovering that the wage gap is narrowing and many of the disadvantages are now starting to outweigh benefits of sending jobs abroad. One of the points mentioned in the article is that wages in china have risen 10-20% in the last 10 years, whereas wages in America and Europe have remained about the same. Also, another disadvantage of send production abroad is that shipping can be very expensive. In recent years shipping costs have gotten higher such that the cost of producing elsewhere and shipping to the US is no longer as cheap as it used to be. The time factor is also a big issue. Many times transit takes as long as six weeks which makes it hard for companies to fulfill their orders in a timely manner. In conclusion, the article makes a note that a lot of companies are now rethinking their decision about going offshore. Opinion Most of the companies went offshore to save money, and I can see where they are coming from after all the whole goal of having a business is to make profits however in my opinion many of the companies did not take the time to properly analyze the other costs involved in moving jobs offshore. Many also forgot to consider how it will affect the quality of their service when it comes to shipping time and sometimes the quality of the product. I am very happy that many jobs are coming back and I think the government needs to do more to encourage the companies. They should offer tax reductions where necessary so that America will be able to compete in the global market. I also like the point the article makes, that just because companies are tending towards reducing offshoring does not mean they will be less global, infact distributing their activities more evenly around the globe will make most companies more efficient.

The Materials Management In Malaysia Construction Construction Essay

The Materials Management In Malaysia Construction Construction Essay In construction, materials and equipment account for 50-60 of the project cost, and the most common cause of delays in construction is lack of materials (Amir Tavakoli  Ã‚  Adil Kakalia, 1993). Studies conducted by the Construction Industry Institute, American Association of Cost Engineers, and others have emphasized the importance of construction materials management (Amir Tavakoli  Ã‚  Adil Kakalia, 1993). These studies have concluded that effective materials management system will result in a 6-8% improvement in labour productivity, improved cash flow, reduced bulk materials surplus, reduced materials management human resource, improved vendor performance, reduced requirement for physical warehouse facilities, quantity purchasing discounts, minimized cost impact of change orders, and fewer project delays. The saving made as a result of these improvements outstrip the cost of implementing a materials management system by ten to one (Amir Tavakoli  Ã‚  Adil Kakalia, 1993). Nowadays, the cost of materials for construction is increasing form year to year due to market force, lack of natural resources, and etc. In order to reduce the construction cost, material management has to be carrying out to control the construction cost to make more profit. 1.2 Problem statement Lack of materials management in construction will result in rising of construction cost, more wastage, lowering the profit and etc. In order to make a higher profit with a high construction cost, developer tend to sell their development in a higher price and hence building cost will become higher and result in purchaser have to pay a larger afford on the payment. Government should pay more afford to contractor on materials management in order to reduce wastage as nowadays our world is more concern in recycle and also to reduce the afford of people to buy a comfort residential for themselves or to get a shop to undergoes their business. 1.3 Objectives 1. To identify whether the materials management system are properly carried out in construction site. 2. To determine the proper way in carrying out materials management on construction site. 2. To determine the advantages of the used of materials management. 1.4 Rationale of study Building materials is a important resources in a construction industry. No matter how big or small the project is, contractor should pay more attention on building materials in order to reduce wastage and also to maximize their profit. Many construction companies still do not do well in materials management which can help them to make more profit and also to help their construction running smoothly. So, there are some reasons why this research needs to be carried out. First of all, how to applied and organised the proper materials management system to a project. Secondly, how to increase the profit of construction company by the used of materials management system. Hopefully, this research will give a clear picture on materials management and provide a guideline for local construction company to improve their materials management system. 1.5 Methodology Methodology method to be used is questionnaires. First, aims and objectives will be planned and draft out all the content needed. After finalize the survey questionnaire, 30 samples will be conducted by sending to different construction company. The targeted constructions companies contacts are obtain from internet, friends and newspaper. After collected the questionnaires, the data collected will be analyze. Conclusion and recommendations will have made at the end of the research. The purpose of using questionnaires is that it can be compare different ways of materials management system carried out by different construction company and this also is an easy way to collect data. Chapter 2 Literature review 2.1 Definition Materials management is an organizational philosophy that has evolved through application of the systems approach to management, an approach that provides for integration of all management functions. A primary objective of this philosophy is to coordinate all business activities that are part of the materials cycle, from supplier through company operations and on to the customer. Materials management is an umbrella that integrates all the critical materials sub functions and , as such, is a major company function, among such others as engineering, finance, and manufacturing as show in figure 1.1(Eugene L. Magad and John M. Amos, 1995): Capture Figure : Major company function cooperating to achieve common objectives A simpler definition of materials management could be the line of responsibility which begins with the selection of suppliers and ends when the material is delivered to its point of use. (Dean S. Ammer, 1969). Material managements is a concept which brings together under one manager the responsibility for determining the manufacturing requirements, scheduling the manufacturing process, and procuring, storing and dispersing material. As such it is concerned with, and control, activities involved in the acquisition and use of all material employed in the production of a finished good. (R J Carter and P M Price, 1993) 2.2 Concept Neither the terminology nor the concept of a totally integrated material organization has been accepted by all business throughout the world. Many of the local company use the different term to coding this management such as Material Management, logistics, and Physical distribution for similar organizations. Others have embraced the title but not the full organizational philosophy. Despite different names, however, the trend in recent years has been for companies to adopt the materials management or logistics management title. (Eugene L. Magad and John M. Amos, 1995) Business costs attributable to material are significant portion of the total cost of goods and services. Increasingly, companies are recognizing the need to implement this type of organization to maximize profits, improve customer service, establish needs controls, and reduce costs. (Eugene L. Magad and John M. Amos, 1995) 2.3 Functions of Material Management In building construction industry, Material Management works with all departments, the major function is to provide the right materials to the right operating point at the right time in a usable condition and at the minimum cost. So, in generally the Material Management play an important role whether the profit the Contractors firm will maximize or remain unchanged. (R.J.Carter and P.M Price, 1993) Besides that, the amount of wastage also reduced with the used of materials management as nowadays what our community concern more about in the term of Recycle. Below are the basic function of the use of materials management in construction industry: Classification of materials Location on site Movement on site Reduction of waste Quality Control The main point of Material Management is to satisfy the needs of all operating systems, such as the manufacturing production line, the need arising from customer demand patterns, promotional activities and physical distribution schedules. (Ian E Chandler, 1978) 2.3.1 Classification of materials Materials can be classified into groups reflecting the manner in which they can be handled and stored on the site. The way in which a material is delivered will determine how it is offloaded and where it is located. For example, sand will arrive in a tip-up body vehicle and will need to deposit onto an even clean base with walls to prevent excessive spreading. No labour will be required other than an operative directing the vehicle. (Ian E Chandler, 1978) The classification can be divided into five broad areas. Bulk The material is delivered in bulk and deposited on site into some form of container. These materials have a high wastage rate and tend to be used indiscriminately. (Ian E Chandler, 1978) Bagged A bulk material placed in bags for ease of handling and controlled use in small quantities. The bag also offers some protection against wastage and deterioration. Generally, to ensure speedy unloading a large number of operatives are required to carry the bags to the storage point. (Ian E Chandler, 1978) Palleted Bagged materials can be loaded onto pallets on the transport vehicle and on arrival at the site mechanical means can be used to offload them, such as fork lift trucks or cranes. (Ian E Chandler, 1978) Packaged An increasing number of materials are packaged to prevent damage during transit and deterioration in storage. They can be banded together fully enclosed or just protected at their most vulnerable parts. (Ian E Chandler, 1978) Loose Components are in a partially fabricated state it may not be feasible to pallet or package them. They will have to handled individually according to their weight, size and intrinsic strength. (Ian E Chandler, 1978) The firms policy should be, wherever possible, to obtain the materials either palette or packaged. This will generally involve the buyer in negotiations with the suppliers to determine the most suitable requirements. There are advantages that will be of benefit to both parties: (Ian E Chandler, 1978) Faster turn-round for vehicles on site Quicker and easier loading at the source Possible rationalization of pallet sizes and loads, together with package sizes. As a summary for classification of materials by classify the materials into five groups, it can help to aid the site management in determining the handling and storage policy and practice it needs to carry out on the site. The manner in which the material is delivered will determine its storage location, when it will be required, and how it will be off-loaded and transported. (Ian E Chandler, 1978) 2.3.2 Location on site The overriding objective of the location of materials and components on the site is that they should be as close to the point of use as is practically and economically possible. (Ian E Chandler, 1978) When materials are delivering from a far distance to the site, it will result in wasting time in delivering, risk of damage to the materials and also an increase in the cost of materials. It is necessary that the distance of the delivering materials to be managed. In develop a plan for this management, the factor which will affect the plan is the time, space, labour, plant and costs. Time. If the contract has to be completed in a relatively short time compared to similar projects, then the cost of material handling becomes a secondary consideration. It is necessary to stock-pile materials to cushion the effects of irregular delivery. This will have to be re-handled at a later date if they are deposited some distance away from the point of use. The net effect on the programme in achieving continuous production to obtain completion on time may, in this particular case, justify the extra expenditure for the double handling. (Ian E Chandler, 1978) Space. On the majority of sites the space available for the storage and movement of materials and components is the major consideration. The amount of land left around a building or a group of building is restricted owning to design and cost factors. The cost of land is very high, owing mainly to its scarcity value for building, this means that the building will take up as much as of the available land area. The developer must achieve a balance between a high density of population and areas for leisure amenities. (Ian E Chandler, 1978) Labour and plant. The off-loading and handling of materials in site which should be carry out by worker or machine has to be done correctly. The important of this is more main on time as time is very important for construction. For example, by using a crane to lift concrete to a high floor is much for faster than carrying by worker as the amount to be lifted is much larger and the time used is much more shorter. But there still many item that must be carry by worker such as some small item which carry only a small amount and easily broken item should be carry by worker carefully to avoid losing or damage to the item. Costs. Whatever the outcome of looking at the location problem from the point of view of time, space or labour and plant the ultimate decision will inevitably be tempered by the cost factor. If the costs exceed the budget for that particular operation a decision will have to be taken in the best interests of the project. It may be justifiable to exceed the estimate for one activity in order to produce a saving in another. If after a number of feasible solutions have been obtained on the basis of the other limiting factors, then the distinguishing criteria will be cost, with the problem being solved by using the cheapest method. (Ian E Chandler, 1978) 2.3.3 Movement on Site Movement on site mean to move the material from 1 position to another position. Incorrect ways of movement might cause damage to the materials and increase the costs. Basically, movement on site can be divided into 2 types which is horizontal movement and vertical movement. For horizontal movement, the aim is to ensure that the material is moved from one position to another over the site to minimize time, handling, damage and costs by using routes planned to ensure safety and ease travel. The routes should be defined by laying roads or marking their width. Material checker should have the responsibility and authority to police the activity. (Ian E Chandler, 1978) Plant should be well maintained to avoid break down of vehicle in the way of delivery or any other to avoid wasting time on delivery. This might cause delay of construction when materials deliver to the site late and hence causes lost to the contractor. While for vertical movement, this is the movement of materials from one level to another in either a strict perpendicular manner or with a certain amount of horizontal movement. (Ian E Chandler, 1978) Very little vertical movement, except in single or two storey buildings, is carried out by labour excluding for example, bricks and mortar in hods and the placing of sanitary fittings. Labours intensive lifting is expensive both in time and money. The optimum is to get the materials to the required level in the most efficient way. Lifting plant should be positioned around the building to ensure that excessive horizontal movement within the structural envelope is minimized. It should be positioned around the structural envelope is minimized. It should be able to carry component that needs to lifted, also bearing in mind its overall size. The load must be carried safelt and should be secured if there is the slightest danger of it falling. If the lifting conveyance is fixed provision has to be made to prevent the load falling outside the area occupied by the lift appliance. (Ian E Chandler, 1978) The amount of space on site will determine the allocation of the horizontal and vertical movement corridors, with an inherent danger of excessive travel by the site transport on an unlimited site and detailed planning required on a restricted one. The mode of transport to the site will affect how and where the materials will be offloaded. Site corridors should be designated according to vehicle or pedestrian use and prepared according to the loads they will have to convey. The type of transport will have to convey. The type of transport will have to be decided at the planning stage to ensure that deliveries can be handled efficiently. Vertical movement will depend upon the materials to be lifted and the height they have to reach. (Ian E Chandler, 1978) 2.3.4 Reduction of Waste Contractors are often active in the design phase when involved in design-build, construction management at risk, and agency construction management contractual relationships. This early involvement in the process provides the opportunity to help build realistic specifications for reducing waste in the construction process. (William R. Mincks Hal Johnston, 2012) Designers are typically aware of the physical attributes of materials; however, they dont usually consider the waste generated by the use of the material in the construction process. The contractor ia aware of the efficient use of material and its waste in each application. This insight can help the designer choose the optimal material for each particular use. (William R. Mincks Hal Johnston, 2012) The specification need to reflect what the owner is intending to accomplish concerning waste management. The specification should include requirements to achieve reduction of waste, such as requiring detailed waste management plans form the contractor and trade contractors on the jobsite. (William R. Mincks Hal Johnston, 2012) Waste is generated in a systematic process that can be scheduled. Begin making schedule requirements that will illustrate when and how waste will be generated. The schedule should be used to better understand waste generation and how best to recycle, reuse, or dispose of the different kinds of materials being used on the project. (William R. Mincks Hal Johnston, 2012) Figure 2.0 shows the composition of construction waste. C:UsersUserDesktopwaste.PNG Figure : Composition of construction waste Closer cooperation between designer and contractor in the design stages of building can help to prevent waste. The present form of competitive tendering produces a waste of contractors management resources in the synthesis of an unaccepted tender. This is also reflected in the successful tender in so much as the contractor will have had little or no influence over the design. His experience could have alleviated some of the waste brought about by inherent design factors. The incidence of waste has repercussions throughout the contract. Its effect will be seen through extra administrative work by management personnel, an increase in contract time, reallocation of labour, extra costs in replacement of materials, remedying faulty work because of materials, and extra costs in cleaning and disposing of waste materials. (Ian E Chandler, 1978) 2.3.5 Quality Control According to Sidney M. Levy (2007), the control of quality construction begins with an intensive review of the plans and specifications. There may be few deficiencies in the plans and specifications, some of which may have been uncovered during the estimating process, while other were unearthed by the subcontractor and vendors. The project superintendent may have unearthed constructability issues during his or her review. The need for all parties to thoroughly examine the documents under their control cannot be overemphasized. When problem are uncovered early in the game, the impact and associated costs are considerably less. Quality control is the function which must be performed throughout an organization in order to achieve its quality objectives. To produce effective quality control of incoming materials and components a practical site based system must be adopted. The control of work-in-progress will not be discussed unless it overlaps the system to be applied to materials. (Ian E Chandler, 1978) Component of building is cannot without the present of quality control because of the interrelationship of each others. The quality must set at the target where it is likely possible to achieved and sufficient. If the target of quality is arrange out of the capability, it not just wasting the time but also create delay of the project. So, quality control is not just based on what quality standard is to be achieved, but it is also based on the existing techniques and capability to control the quality. In order to control the quality of materials, materials can be inspected by 3 method which is visual method, tactile method, and statistical method. Inspection is not carried out by using either one of these methods but by according to the type of materials by using which method. Inspection is preferred to be carry out before the materials are unloaded as this can avoid unnecessary defective hence to prevent from wasting time and energy to demolish and rebuild. Visual inspection is generally only possible if the items are not packaged and where the quality can be seen at a glance, eg timber. During unloading some damaged goods may be found if a competent person is in charge. If it is left to untrained operatives to unload, damage may be caused and defective items not noticed and their importance realized. Checks should be carried out prior to and during unloading, with a final check on the method of protection. The vast majority of quality control checks are visual and defective material is generally easily recognized. (Ian E Chandler, 1978) For tactile inspection, from the appearance of a material it may be seen to be defective or of a poor quality but by touching it this can be confirmed. This method of inspection has only a limited application and is usually confined to materials such as sand, cement, plaster and joinery timber. (Ian E Chandler, 1978) By using statistical techniques on samples from bulk deliveries the state of the whole deliver can be fairly accurately forecast. It is not intended to describe here the mathematics behind these techniques but to show where they can be applied on the site. The most common sampling test used is the concrete cube test. A quality if concrete is taken from a batch, and compacted into a number of cast iron cubes. These are allowed to cure for a specific number of days and then the concrete cubes are tested for compressive strength. It is assumed that the cubes represent the whole batch of concrete and that the results of the tests on the sample reflect the expected results if all the concrete was tested. This same technique can be used on bricks, aggregate, timber, and components. (Ian E Chandler, 1978) Suggested by Ian E Chandler (1978), to be effective a quality control system should be based on a close liaison between the architect and the builder. A system should be developed in conjunction with the general materials handling procedures and this carried out under the responsibility of the person in control of materials. The system must be set the quality standard, plan how it is to be adopted, implement the methods of inspection and provide for a long term control of quality. An efficient system will cover its costs, ensure that a job is executed to the satisfaction of the architect and possibly provide and additional saving for the contractor. With strict control, pressure can be brought to bear on the materials suppliers and with good quality materials a high standard of workmanship can be achieved in creating the finished article. 2.4 Advantages of Material Management in Building Construction In Building construction industries, what is the advantages of Material Management will bring the benefit to Contractors Company. In fact, the adoption of Material Management by the Contractors Company will generate a number of significantly valuable advantages in terms of total organizational control and materials control. In according to Eugene L. Magad and John M. Amos (1995), the advantages are as follows: Maximun company profit Improved customer service Improvement of credibility Enhancement of communication Improved quality of staff 2.4.1 Maximum company profit According to Eugene L. Magad and John M. Amos (1995), like other major company functions, Material Management is mainly responsible to maximize the company profits. Because Material Management control the company 4M which is materials, machines, manpower, and money, it has significant potential for increasing company profits by reducing costs. Cost reduction opportunities are possible throughout the material function. Some typical examples are as follows: Decreasing part shortages (resulting in more efficient use of labour, plant and materials). Reducing inventory level through improved controls. Lowering transportation costs as result of using minimum cost of transport vehicle to send the building materials Always ensure the material is order and send to the site at the suitable time, prevent any material which is brought to the site prematurely. If possible, purchasing manager should order the material in large quantity and enjoy certain amount of discount. (Material in large quantity like cement, timber, and etc where can be store for longer period of time) Material Management can make an important contribution to a companys profit margin by reducing total costs, which can then provide a reduction in Building development price. Reduction development price can result in higher sales during the periods of marketing for completed building, as well as the ability to maintain sales volume during a contracting market. Another benefit achieved by reducing materials cost is that can help a company to maintain the same product (Building) price during periods of increasing resources costs. (Eugene L. Magad and John M. Amos , 1995) According to Elijah E. Ogbadu (2009), materials management and marketing department should cooperate in ensuring the organization for the profitability. Materials management has the ability to produce the exact quality of the materials used to avoid wastage to obtain the lowest possible cost which will then bring marketing maintain competitive advantage. Consequently sales and profit will be increased. 2.4.2 Improved customer service The second benefit of applied the Material Management in building industry is that the product quality provided to the customer will increased. Quality control is part of the essential topic under the Material Management function. In regard with the product quality, the firm which adopted the Material Management system will normally balanced their product cost and quality. It is not true that with the lowest cost of product will decline the quality of the product. When the building sales in the market with the reasonable cost and better quality, then it will constantly maintain the customer product quality and with lower building cost. (Eugene L. Magad and John M. Amos , 1995) 2.4.3 Improvement of credibility An important factor in the day-to-day operation of a company is the reliability and accuracy of each groups performance and activities. Each and group within the company must depend on others for correct timing and performance, if anyone falters, the overall performance is affected. In some respects, company activities are more complex than this. Individual department begin to take safety precautions when they are forced to work with others who are less reliable than they. With a Material Management organization, various functions (marketing, manufacturing, etc) get better, more reliable service. The Material Management organization provides credibility of performance, which helps to reduce costs and lessen confusion. It also contributes to an atmosphere of mutual and cooperation. (Eugene L. Magad and John M. Amos , 1995) 2.4.4 Enhancement of communication The Material Management offer the benefit of enhance the communication by provide a communication network that reacts quickly and facilitates improved rational action throughout the system. Combining the various fragmented groups enhances communication by shortening message channels, allowing common use of data, providing greater potential use of communication through data processing equipment, and encouraging the flow of information between people. (Eugene L. Magad and John M. Amos , 1995) 2.4.5 Improved quality of staff This statement given that the material manager will promote team based working and will offer greater promotion and staff development opportunities, the company will attract a higher capability staff to work together. Majority, the employee will aim for higher status of working environment and also challenging work. The company with systematic organization may attract those experienced staff working within the firm, so the company with Material Management system is form of systematic approach which will create a good image to company. (Eugene L. Magad and John M. Amos , 1995)

Ghana and the Social Contract :: aristotle, family, values, communities

Aristotle rightly said that the family is the building block of the society and each family has its common values and preferences. Even though individuals may belong to the same family and society, they would have diverse opinions on what the society should be and where it should be headed. Even in the face of shared values by a society, there is another discriminant of individual’s value systems- their experiences. These experiences make them masters of themselves because they assume that their experiences are unique to only them and therefore these views should be recognized as valid. James O’Toole categorised the value systems of individuals under the four major themes of community, efficiency, liberty and equality (O'Toole, 1995). This paper reflects on the good society and its constituents in the light of these four themes. O’Toole believes these four are the great themes of political argument which face trade-offs with each other and have an inverse relati onship with each other, that is, an increase in one causes a decrease of the other. Thomas Jefferson considered the good society to be a society in which everyone was happy and I agree with that because happiness is the end product of various favourable factors in a person’s life. Furthermore, I am of the same view that a good society is one that ensures the rights of every member of the society. This is because every human being is innately self-seeking and this is evident in a child’s selfish efforts to attain his or her wants in spite of being young in knowledge of the society. Even though humans can be selfless, their basic needs should at least be met because the satisfaction of their needs sustain them and ensures their contentment. To ensure basic rights of individuals, it is essential to know which value they hold dear, whose fulfilment would bring them long lasting pleasure, thus, leading into the exploration of these major core values. Liberty is concerned with freedom of the individual in three spheres, which are in politics, religion and economics and this value births individuals who are known as libertarians. The modern Libertarian principle that these individuals operate by is that â€Å"the equal right to freedom constitutes the full extent of human equality; all other equalities are unwarranted and unjust† (O'Toole, 1995). Thus, libertarians support every kind of liberty which includes economic liberty hence, capitalism. As such they believe that government interventions in the free market stifle economic progress.

Pity the Bear in Judith Mintys story, Killing the Bear :: Minty Killing the Bear Essays

Pity the Bear in Judith Minty's story, Killing the Bear   Judith Minty's story, "Killing the Bear," is a rather chilling tale about a woman who shoots a bear to death. The story is not merely a simple account of the incident however. It is full of stories and facts about bears, which affect how the reader reacts to the story. In the beginning, the reader expects the bear to be portrayed as a cold-blooded monster who must be killed for the safety of the primary character however this expectation is foiled throughout the story and the reader sees the bear in a very different light. Due to the stories and facts given about bears throughout the story, the reader comes to pity the bear, but most will still acknowledge the necessity of killing him. The beginning of the story seems very quiet and peaceful. It sets up a scene many people would be familiar with. Even the story about the dog is one most people who have ever owned a house pet would instantly recognize. The woman does seem very vulnerable, however. She is outside in a hammock and the dog seems very little help since "she ended up more his protector than the other way around" (2). The second section sets up frightening images of animals, but they are all in the zoo, so they pose no threat. Yet, this still sustains the reader's original expectation of the bear being a threatening animal. Of all the zoo animals described, the bear seems the most harmless, yet she is still afraid of it. The reader has not been shown any danger yet, but there is still a sense of something about to happen. The only bear we have seen is a "bundle of clothes by [a] dead tree" (5) in a cage at the zoo. The third section of the story returns the reader to the calm security, but then quickly sends the tone of the story into a frenzy. These constant tone changes show the reader how strong and resourceful the woman is, but it also shows us how she can be thrown into a panic easily. We come to have little confidence in the main character's ability to react well if a dangerous situation arises. Throughout the story, "Killing the Bear," the reader is given a number of side notes about bears and the woman's experience with them.

alcohol abuse Essay -- essays research papers

Alcoholism is an overwhelming desire to drink alcohol, even though it is causing harm. Alcohol is a drug. In the United States alcoholism is the most widespread form of drug abuse, effecting at least 5 million people. About one third of high school students in the US are thought to be influenced drinkers. Many already may be alcoholics.   Ã‚  Ã‚  Ã‚  Ã‚  A person who is dependent on alcohol is called an alcoholic. Drunk drivers account for one half of all fatal automobile accidents each year in the US. Alcoholism also creates many severe physical problems. More then three drinks a day, over a few weeks causes destructive danger in the liver. Changes in the brain and nervous system result in hostile behavior. A family or individual with an alcoholism problem is in serious trouble because the alcoholic's main goal is to get something to drink. The drinking usually continues until the person is drunk. Family, friends and work are little concern compared to the need for alcohol. Drunkenness limits the alcoholic's control of normal behavior and to perform the easiest functions. Many resources can help but two rules apply to recovery. One is that the alcoholic must accept the fact that there is a real problem and must decide to stop drinking. An alcoholic must also realize that any form of alcohol is literally poison. When in recovery an alcoholic could never take another drink.   Ã‚  Ã‚  Ã‚  Ã‚  First of all you will notice that an alcoholi...

Aliens and Faith Essay

There are many religions throughout our world. Some are even based on the actual worship of what these believers call, Aliens from outer space. The majority of religions though do not believe in intelligent life outside of human beings on planet Earth. Christianity is a main religion practiced worldwide; part of its belief for most believers is just that, that we are the only intelligent life created by the Christian God. The possible existence of extraterrestrial life though does not give reason that religious beliefs are not true. The belief of an omniscient creator of all things, including our never ending expanse of Universe and the possibility of what it holds, show that an omniscient creator’s power is never ending and our faith should be as well. All religions require you to have faith, and with faith we can accept any possibility. When people entertain the idea of extraterrestrial life they feel it casts doubt that the gods or God of many religious beliefs cannot coincide with the reality of life. Quoting an anonymous source, here is one opinion: Christians claim that the Bible has all the knowledge of how, when, where, what and why life was created and everything that God has done. The Bible explains that God created angels and humans and animals on earth. That pretty much covers everything God has created from earth to heaven. If God doesn’t mention aliens in His creations and only speaks of how He sacrificed Himself for us it could be claimed that God did not create any other life form outside earth. I think it would be absurd if God created other life forms in other parts of the universe and gave them free will and then going through another self-sacrifice. Besides, there is only one evil source, namely Satan that serves as our earthly test. This Satan only dwells on earth and not in other worlds. That is why aliens cannot exist. If aliens exist or come to earth it directly proves that Christianity is a fake (QTD). Yet we are taught in this religion in particular to have faith in the God of Christ. That our faith can move mountains or raise the dead, if we just believe, then it can be done. In Him all things are possible. Aliens can still be a possibility even with religious beliefs, extraterrestrials and religion can still exist together. Keeping in tune with the Christian religion, also being the popular religion worldwide, we hear that the catholic faith of Christian belief states that they believe and are researching the existence of extraterrestrial life being a reality. In my opinion this possibility exists,† Funes, the director of the Vatican Observatory, told L’Osservatore Romano. † Astronomers believe the universe is made up of 100 billion galaxies, each of which consists of 100 billion stars,†¦ Life forms could exist in theory even without oxygen or hydrogen. † (News). The Catholic Religion is the oldest Christian based religion historically and is very dominant and deeply rooted with many assets. They will have scientist, astronomers, and researchers continuously providing facts and reasoning behind this coexistence. Ted Peters writes: â€Å"During the formidable period of medieval Scholasticism, despite the forceful impact of Aristotelian philosophy, Christian Theology was by no means wedded to the idea that God created only one world†¦ Not only did some of our best minds affirm the idea of multiple worlds, some even spoke positively regarding the existence of extraterrestrial life. † (Delio 250) There is the belief that any other life forms created where angels or demons and that aliens are not part of these creations. We can show that alien life forms can coexist with even these creations and it not disprove religion still. There are few places in the bible that speak of life outside of humans and none mentioning aliens or extraterrestrial life, but they are there. â€Å"praise ye him , all his angels: praise ye him, all his hosts†¦for he spoke and they were made. He commanded and they were created† (Psalm 148:2). Contrary to popular belief, the Bible does not say that the only intelligent beings populating the universe are humans, in fact God created countless â€Å"non-human intelligent beings† before mankind. God is known throughout the Bible as the Lord of Hosts (Flynn). To show faith in the God of Christ we can believe in the possibility of these beings and it not disprove them. Even in scriptures it does not come out and say it but it gives seed to the idea and possibility that God did create other hosts of this life. On a more general level the fact that alien life exists would mean that we are not the center of the universe. Most religions now recognize that the earth is just a lump of rock, they still believe that WE as human being are the most important thing in creation, that we occupy a special place in God’s plan. The existence of aliens would seem to make this implausible especially if they are more advanced than we are (on all levels, intellectually, spiritually) This would mean that God has acted in the development of the aliens in a away he did not act in ours, which in turn would mean that we do not occupy the paramount role in God’s creation, which as I said is a fundamental idea in religions. For Christianity, Judaism and Islam the existence of aliens is especially problematic. All these religions are based on the idea of a covenant between us and God. Weidemann, a self-confessed Protestant Christian, mentioned a few potential answers. Maybe aliens are not sinners, like human beings, and as a result are not in need of saving. On the other hand, the principle of mediocrity – the notion that own case in point is most likely standard except if there is proof to the opposite – casts skepticism on this, he pointed out. Weidemann stressed that if there are extraterrestrial rational creatures at all, it is safe to believe that virtually all of them are sinners as well. He added that if aliens are sinners Jesus did not save them too. Weidemann asserted that their position among intelligent creatures in the universe would be very outstanding (Delage). With extraterrestrial life in the universe being seen as a possibility and many biblical references giving seed to this as truth, believers maybe are being tested with this theory as another way that we are tested in our faith. We are asked to have faith without seeing, and to believe without question the infinite intelligence of God the infinite possibilities he has, to let the unknown exist and still believe with a faith unfounded.
