Analysis of Charles Dickens’ †Sketches by Boz Essay

‘The Streets-Morning’ by Charles Dickens is an extract taken from ‘Sketches by Boz.’ It is a descriptive piece and follows prominent features of the literary sketch technique, as it contains no prominent plot. The speaker narrates the â€Å"appearance presented by the streets of London an hour before sunrise on a summer’s morning.† The extract is in the first person narrative. This feature adds intensity and supports the use of details. First person narrative is generally considered unreliable due to lack of witnesses and external verification; however, the detached and objective narration by the speaker prompts readers to think otherwise – â€Å"now and then a rakish looking cat runs stealthily†¦bounding first on the water-butt then on the dust hole†¦Ã¢â‚¬  The sentence structures used support the use of detail and imagery. The speaker uses complex-compound sentences that are long with two or more sub-clauses. The use of these help create the atmosphere and heavy early morning slumber – â€Å"There is an air of cold, solitary desolation about the noiseless streets which we are accustomed to see thronged at other times by a busy, eager crowd, and over the quiet, closely shut buildings†¦Ã¢â‚¬  Through this narrative, readers are made aware of the close attention to detail the speaker employs. The mood of the extract is established through the sentence structure and setting. A relaxed and comfortably detached perspective is evident. In many ways it is similar to the morning itself, gently unfolding as the darkness fades. The narrative time and context is established through the subjects described in the setting. â€Å"Coach-stands† lying deserted in the larger thoroughfares remind readers of the 19th century. This is supported by the fact that they are described as ‘coach stands’ and not bus stands. Imagery plays an essential role in a literary sketch and is seen widely in this extract. The speaker uses concrete and abstract imagery. The use of metaphors lends a sense of what the speaker is feeling or trying to describe to the reader. Such metaphors are: â€Å"The days are swarming with life and bustle† the reference to honeybees shows a restlessness which was similarly used by John Keats in ‘Ode to Autumn† – And still more, later flowers for the bees, †¨Until they think warm days will never cease.† The bee metaphor is used to show activity that contrasts with the early morning street. The second metaphor is – â€Å"stillness of death is over the streets,† perhaps the most foreboding of lines in the extract, this metaphor could serve as a possible foreshadowing for impending events. The street itself becomes an important motif. It represents a path that leads somewhere, however, readers could question whether this could be leading to activity or stagnation. This theory is supported with the images of the â€Å"drunken, the dissipated, and the wretched.† The policeman similarly, is also preoccupied with his â€Å"deserted prospect.† The description of the street is similarly presented in Tennessee Williams’ ‘A Streetcar Named Desire†Ã¢â‚¬â€œ â€Å"The houses mostly white frame, weathered grey with rickety outside stairs and galleries and quaintly ornamented gables to the entrances of both. It is the first dark of an evening in early May.† The houses become symbols of who their inhabitants are in the extract. They give readers insights to where they live, how they live and who they are. The â€Å"quiet, closely-shut buildings† are perhaps the only privacy the residents have. The speaker brings in social context through this description and the tone shifts to one of fragmentation and futility with the description of – â€Å"The last houseless vagrant whom penury and police have left in the streets, has coiled up his chilly limbs in some paved corner, to dream of food and warmth.† The social context and strata becomes ironic when the last drunken man is home before sunlight, while the â€Å"orderly† part of the population are still asleep.† The opening lines of T.S. Eliot’s ‘Preludes’ also refers to an early morning scene similar to the one in the extract, using personification – â€Å"The morning comes to consciousness Of faint stale smells of beer From the sawdust-trampled street With all its muddy feet that press To early coffee-stands.† Human qualities are given to the cat who is – â€Å"rakish looking.† The character of whose develops as the speaker gives him gender and infers that â€Å"his character depended on his gallantry.† The use of personification adds further detail to the narrative with – â€Å"A partially opened bedroom-window here and there, bespeaks the heat of the weather, and the uneasy slumbers of its occupant.† The extract uses language in distinct and deliberate ways to shape meaning. The vocabulary used helps infer that the speaker is mature; this is seen with use of words such as â€Å"penury,† â€Å"profligate† and â€Å"dissipated.† A sentence of importance in shaping such meaning is – â€Å"The drunken, the dissipated and the wretched have disappeared.† The trochaic features at the end of each word, helps to reveal the distant and condescending manner in which the speaker is viewing these people. The order in which these words are presented form a climatic effect. Also seen is the use of the adverb â€Å"then† in describing the cat’s actions, which gives dramatic effect – â€Å"Bounding first on the water-butt, then on the dust-hole, and then alighting on the flag-stones.† The use of inversion by the speaker helps readers to concentrate on certain parts of the narrative. This is done in deliberation to gain readers’ attention, particularly in – â€Å"An occasional policeman may alone be seen at the street corners,† as opposed to the conventional ‘may be seen alone.’ Such emphasis is also used in – â€Å"cold, solitary desolation.† The speaker employs onomatopoeia to describe a drunken man’s inebriation with – â€Å"roaring out the burden of the drinking song of the previous night.† The speaker has a noted tone of detached indifference. This mood could be due to the futility of the modern age and monotony of these peoples lives in the eyes of a keen observer. The historical, social context comes back to the forefront and the void between the country and the urban life is seen. This effect of the 19th century and industrial revolution is addressed in – â€Å"The few whose unfortunate pursuits of pleasure, or scarcely less unfortunate pursuits of business cause them to be less acquainted with the scene.† Grammar and punctuation support meaning. The use of dashes shows a flow of thought or in the case of describing the cat, shows action and continuity. The use of the color grey in the â€Å"somber light of daybreak† supports the mood and futile atmosphere, seen also in O’ Henry’s ‘Gift of the Magi’ – â€Å"Della finished her cry and attended to her cheeks with the powder rag. She stood by the window and looked out dully at a gray cat walking a gray fence in a gray backyard.† The extract concludes with a reference to the figures in the early morning streets as â€Å"exceptions† other than which the â€Å"streets presents no signs of life, nor the houses of habitation.†

In the 2004-05  fiscal year, it is the  Steel Authority of India Limited's most profitable plant. This steel plant was set up with the help of the USSR. Nine – time winner of Prime Minister's Trophy for best Integrated Steel Plant in the country. The plant is the sole supplier of the country's longest rail tracks of 260 metres. With an annual production capacity of 3. 53 MT of saleable steel, the plant also specializes in other products such as wire rods and merchant products. Since BSP is accredited with ISO 9001:2000 Quality Management System Standard, all saleable products of Bhilai Steel Plant come under the ISO umbrella. At Bhilai IS0:14001 have been awarded for Environment Management System in the Plant, Township and Dalli Mines. It is the only steel plant to get certification in all these areas. The Plant is accredited with SA: 8000 certification for social accountability and the OHSAS-18001 certification for Occupational health and safety.These internationally recognised certifications add value to Bhilai's products the best organizations in the steel industry. Among the long list of national awards it has won, Bhilai has bagged the CII-ITC Sustainability award for three consecutive years. Bhilai Steel Plant manages a well planned township (Bhilainagar) which as 13 sectors. It was deliberately located in what was then regarded as a remote and â€Å"backward† rural area, profits being secondary to employment in the planning priorities of the time.BSP currently has nearly 55,000 permanent workers on its direct pay-roll, of whom approximately three-fifths work inside the 17 square kilometer plant and the remainder for its associated mines and quarries, and for the purpose-built BSP township. This compares with a regular workforce of 63,400 in 1987. In addition, on any one day there are at present something in the region of 8,000 contract workers employed by the plant and the township, and a further 3,500 – 4,000 employed by the mines. BSP has for some years shown a profit, and is widely regarded as the most successful of those in the Indian public sector.It runs at its four million ton capacity; produces cheaper steel, and has a record of considerably more harmonious industrial relations than any of the other state-run steel plants, and also than the vast majority of private sector factories which now surround it, and for which it served as a magnet. Though local job creation was one of its main objectives,  and though the principle was soon established that one member from every family which had relinquished land should have an automatic right to BSP employment, the local Chhattisgarhis were initially reluctant recruits.Location : Forty kms west of Raipur, the capital city of Chhattisgarh, along the Howrah-Mumbai railway line and the Gr eat-Eastern highway, stands Bhilai Steel Plant (BSP).

HEAVY MAINTENANCE ELECTRICALS MAINTENANCE OF MOTORSThe key to minimizing motor problems is scheduled routine inspection and service. The frequency of routine service varies widely between applications. Including the motors in the maintenance schedule for the driven machine or general plant equipment is usually sufficient. A motor may require additional or more frequent attention if a breakdown would cause health or safety problems, severe loss of production, damage to expensive equipment or other serious losses. Written records indicating date, items inspected, service performed and motor condition are important to an effective routine maintenance program.From such records, specific problems in each application can be identified and solved routinely to avoid breakdowns and product ion losses. The routine inspection and servicing can generally be done without disconnecting or disassembling the motor. It involves the following factors: Dirt and Corrosion: 1. Wipe, brush, vacuum or blow accumulated dirt from the frame and air passages of the motor. Dirty motors run hot when thick dirt insulates the frame and clogged passages reduce cooling air flow. Heat reduces insulation life and eventually causes motor failure. 2. Feel for air being discharged from the cooling air ports.If the flow is weak or unsteady, internal air passages are probably clogged. Remove the motor from service and clean. 3. Check for signs of corrosion. Serious corrosion may indicate internal deterioration and/or a need for external repainting. Schedule the removal of the motor from service for complete inspection and possible rebuilding. 4. In wet or corrosive environments, open the conduit box and check for deteriorating insulation or corroded terminals. Repair as needed. Lubrication: Lubrica te the bearings only when scheduled or if they are noisy or running hot.Do NOT over-lubricate. Excessive grease and oil creates dirt and can damage bearings. Heat, Noise and Vibration: Feel the motor frame and bearings for excessive heat or vibration. Listen for abnormal noise. All indicate a possible system failure. Promptly identify and eliminate the source of the heat, noise or vibration. Winding Insulation: When records indicate a tendency toward periodic winding failures in the application, check the condition of the insulation with an insulation resistance test. Such testing is especially important for motors operated in et or corrosive atmospheres or in high ambient temperatures. Brushes and Commutators (DC Motors): 1. Observe the brushes while the motor is running. The brushes must ride on the commutator smoothly with little or no sparking and no brush noise (chatter). 2. Stop the motor. Be certain that: * The brushes move freely in the holder and the spring tension on each brush is about equal. * Every brush has a polished surface over the entire working face indicating good seating. * The commutator is clean, smooth and has a polished brown surface where the brushes ride.NOTE: Always put each brush back into its original holder. Interchanging brushes decreases commutation ability. * There is no grooving of the commutator (small grooves around the circumference of the commutator). If there is grooving, remove the motor from service immediately as this is a symptomatic indication of a very serious problem. 3. Replace the brushes if there is any chance they will not last until the next inspection date. 4. If accumulating, clean foreign material from the grooves between the commutator bars and from the brush holders and posts. 5.Brush sparking, chatter, excessive wear or chipping, and a dirty or rough commutator indicate motor problems requiring prompt service. Figure 1. Typical DC Motor Brushes and Commutator Brushes and Collector Rings (Synchronous Mot ors) 1. Black spots on the collector rings must be removed by rubbing lightly with fine sandpaper. If not removed, these spots cause pitting that requires regrinding the rings. Figure 2. Rotary Converter Armature Showing Commutator And Slip Rings. 2. An imprint of the brush, signs of arcing or uneven wear indicate the need to remove the motor from service and repair or replace the rings. . Check the collector ring brushes as described under â€Å"Brushes and Commutators†. They do not, however, wear as rapidly as commutator brushes. BEARING LUBRICATION: Introduction Modern motor designs usually provide a generous supply of lubricant in tight bearing housings. Lubrication on a scheduled basis, in conformance with the manufacturer's recommendations, provides optimum bearing life. Thoroughly clean the lubrication equipment and fittings before lubricating. Dirt introduced into the bearings during lubrication probably causes more bearing failures than the lack of lubrication.Too mu ch grease can over pack bearings and cause them to run hot, shortening their life. Excessive lubricant can find its way inside the motor where it collects dirt and causes insulation deterioration. Many small motors are built with permanently lubricated bearings. They cannot and should not be lubricated. OILING SLEEVE BEARINGS: As a general rule, fractional horsepower motors with a wick lubrication system should be oiled every 2000 hours of operation or at least annually. Dirty, wet or corrosive locations or heavy loading may require oiling at three-month intervals or more often.Roughly 30 drops of oil for a 3-inch diameter frame to 100 drops for a 9-inch diameter frame is sufficient. Use a 150 SUS viscosity turbine oil or SAE 10 automotive oil. Some larger motors are equipped with oil reservoirs and usually a sight gage to check proper level. (Fig. 3) As long as the oil is clean and light in colour, the only requirement is to fill the cavity to the proper level with the oil recommen ded by the manufacturer. Do not overfill the cavity. If the oil is discoloured, dirty or contains water, remove the drain plug. Flush the bearing with fresh oil until it comes out clean.Coat the plug threads with a sealing compound, replace the plug and fill the cavity to the proper level. When motors are disassembled, wash the housing with a solvent. Discard used felt packing. Replace badly worn bearings. Coat the shaft and bearing surfaces with oil and reassemble. Figure 3. Cross Section of the Bearing System of a Large Motor GREASING BALL AND ROLLER BEARINGS: Practically all Reliance ball bearing motors in current production are equipped with the exclusive PLS/Positive Lubrication System. PLS is a patented open-bearing system that provides long, reliable bearing and motor ife regardless of mounting position. Its special internal passages uniformly distribute new grease pumped into the housing during regreasing through the open bearings and forces old grease out through the drain hole. The close running tolerance between shaft and inner bearing cap minimizes entry of contaminants into the housing and grease migration into the motor. The unique V-groove outer slinger seals the opening between the shaft and end bracket while the motor is running or is at rest yet allows relief of grease along the shaft if the drain hole is plugged. Figure 4) The frequency of routine greasing increases with motor size and severity of the application as indicated in Table 1. Actual schedules must be selected by the user for the specific conditions. During scheduled greasing, remove both the inlet and drain plugs. Pump grease into the housing using a standard grease gun and light pressure until clean grease comes out of the drain hole. If the bearings are hot or noisy even after correction of bearing overloads (see â€Å"Troubleshooting†) remove the motor from service. Wash the housing and bearings with a good solvent. Replace bearings that show signs of damage or wear.Rep ack the bearings, assemble the motor and fill the grease cavity. Whenever motors are disassembled for service, check the bearing housing. Wipe out any old grease. If there are any signs of grease contamination or breakdown, clean and repack the bearing system as described in the preceding paragraph. Figure 4. Cross Section of PLS Bearing System (Positive Lubrication System) HEAT, NOISE AND VIBRATION Heat Excessive heat is both a cause of motor failure and a sign of other motor problems. The primary damage caused by excess heat is to increase the aging rate of the insulation. Heat beyond the insulation's rating shortens winding life.After overheating, a motor may run satisfactorily but its useful life will be shorter. For maximum motor life, the cause of overheating should be identified and eliminated. As indicated in the Troubleshooting Sections, overheating results from a variety of different motor problems. They can be grouped as follows: * WRONG MOTOR: It may be too small or have the wrong starting torque characteristics for the load. This may be the result of poor initial selection or changes in the load requirements. * POOR COOLING: Accumulated dirt or poor motor location may prevent the free flow of cooling air around the motor.In other cases, the motor may draw heated air from another source. Internal dirt or damage can prevent proper air flow through all sections of the motor. Dirt on the frame may prevent transfer of internal heat to the cooler ambient air. * OVERLOADED DRIVEN MACHINE: Excess loads or jams in the driven machine force the motor to supply higher torque, draw more current and overheat.

Motor Operating Conditions Motor Horsepower| Light Duty(1)| Standard Duty(2)| Heavy Duty(3)| Severe Duty(4)| Up to 7-1/2 10 to 40 50 to 150 Over 150| 10 years 7 years 4 years 1 year| 7 years years 1-1/2 years 6 months| 4 years 1-1/2 years 9 months 3 months| 9 months 4 months 3 months 2 months| * Light Duty: Motors operate infrequently (1 hour/day or less) as in portable floor sanders, valves, door openers. * Standard Duty: Motors operate in normal applications (1 or 2 work shifts). Examples include air conditioning units, conveyors, refrigeration apparatus, laundry machinery, woodworking and textile machines, water pumps, machine tools, garage compressors. * Heavy Duty: Motors subjected to above normal operation and vibration (running 24 hours/day, 365 days/year).Such operations as in steel mill service, coal and mining machinery, motor-generator sets, fans, pumps. * Severe Duty: Extremely harsh, dirty motor applications. Severe vibration and high ambient conditions often exist. * EXCESSIVE FRICTION: Misalignment, poor bearings and other problems in the driven machine, power transmission system or motor increase the torque required to drive the loads, raising motor operating temperature. * ELECTRICAL OVERLOADS: An electrical failure of a winding or connection in the motor can cause other Windings or the entire motor to overh eat. Noise and VibrationNoise indicates motor problems but ordinarily does not cause damage. Noise, however, is usually accompanied by vibration. Vibration can cause damage in several ways. It tends to shake windings loose and mechanically damages insulation by cracking, flaking or abrading the material. Embrittlement of lead wires from excessive movement and brush sparking at commutators or current collector rings also results from vibration. Finally, vibration can speed bearing failure by causing balls to â€Å"brinnell,† sleeve bearings to be pounded out of shape or the housings to loosen in the shells.Whenever noise or vibrations are found in an operating motor, the source should be quickly isolated and corrected. What seems to be an obvious source of the noise or vibration may be a symptom of a hidden problem. Therefore, a thorough investigation is often required. Noise and vibrations can be caused by a misaligned motor shaft or can be transmitted to the motor from the d riven machine or power transmission system. They can also be the result of either electrical or mechanical unbalance in the motor. After checking the motor shaft alignment, disconnect the motor from the driven load.If the motor then operates smoothly, look for the source of noise or vibration in the driven equipment. If the disconnected motor still vibrates, remove power from the motor. If the vibration stops, look for an electrical unbalance. If it continues as the motor coasts without power, look for a mechanical unbalance. Electrical unbalance occurs when the magnetic attraction between stator and rotor is uneven around the periphery of the motor. This causes the shaft to deflect as it rotates creating a mechanical unbalance. Electrical unbalance usually indicates an electrical failure such as an open tator or rotor winding, an open bar or ring in squirrel cage motors or shorted field coils in synchronous motors. An uneven air gap, usually from badly worn sleeve bearings, also pr oduces electrical unbalance. The chief causes of mechanical unbalance include a distorted mounting, bent shaft, poorly balanced rotor, loose parts on the rotor or bad bearings. Noise can also come from the fan hitting the frame, shroud, or foreign objects inside the shroud. If the bearings are bad, as indicated by excessive bearing noise, determine why the bearings failed.Brush chatter is a motor noise that can be caused by vibration or other problems unrelated to vibration. WINDINGS: Care of Windings and Insulation Except for expensive, high horsepower motors, routine inspections generally do not involve opening the motor to inspect the windings. Therefore, long motor life requires selection of the proper enclosure to protect the windings from excessive dirt, abrasives, moisture, oil and chemicals. When the need is indicated by severe operating conditions or a history of winding failures, routine testing can identify deteriorating insulation.Such motors can be removed from service and repaired before unexpected failures stop production. Whenever a motor is opened for repair, service the windings as follows: 1. Accumulated dirt prevents proper cooling and may absorb moisture and other contaminants that damage the insulation. Vacuum the dirt from the windings and internal air passages. Do not use high pressure air because this can damage windings by driving the dirt into the insulation. 2. Abrasive dust drawn through the motor can abrade coil noses, removing insulation. If such abrasion is found, the winding should be revarnished or replaced. . Moisture reduces the dielectric strength of insulation which results in shorts. If the inside of the motor is damp, dry the motor per information in â€Å"Cleaning and Drying Windings†. 4. Wipe any oil and grease from inside the motor. Use care with solvents that can attack the insulation. 5. If the insulation appears brittle, overheated or cracked, the motor should be revarnished or, with severe conditions, rewou nd. 6. Loose coils and leads can move with changing magnetic fields or vibration, causing the insulation to wear, crack or fray. Revarnishing and retying leads may correct minor problems.If the loose coil situation is severe, the motor must be rewound. 7. Check the lead-to-coil connections for signs of overheating or corrosion. These connections are often exposed on large motors but taped on small motors. Repair as needed. 8. Check wound rotor windings as described for stator windings. Because rotor windings must withstand centrifugal forces, tightness is even more important. In addition, check for loose pole pieces or other loose parts that create unbalance problems. 9. The cast rotor rods and end rings of squirrel cage motors rarely need attention.However, open or broken rods create electrical unbalance that increases with the number of rods broken. An open end ring causes severe vibration and noise. TESTING WINDINGS Routine field testing of windings can identify deteriorating ins ulation permitting scheduled repair or replacement of the motor before its failure disrupts operations. Such testing is good practice especially for applications with severe operating conditions or a history of winding failures and for expensive, high horsepower motors and locations where failures can cause health and safety problems or high economic loss.The easiest field test that prevents the most failures is the ground-insulation or 127 megger test. It applies DC voltage, usually 500 or 1000 volts, to the motor and measures the resistance of the insulation. NEMA standards require a minimum resistance to ground at 40 degrees C ambient of 1 mega ohm per kv of rating plus 1 mega ohm. Medium size motors in good condition will generally have mega ohmmeter readings in excess of 50 mega ohms. Low readings may indicate a seriously reduced insulation condition caused by contamination from moisture, oil or conductive dirt or deterioration from age or excessive heat.One megger reading for a motor means little. A curve recording resistance, with the motor cold and hot, and date indicates the rate of deterioration. This curve provides the information needed to decide if the motor can be safely left in service until the next scheduled inspection time. The megger test indicates ground insulation condition. It does not, however, measure turn-to-turn insulation condition and may not pick up localized weaknesses. Moreover, operating voltage peaks may stress the insulation more severely than megger voltage.Experience and conditions may indicate the need for additional routine testing. A test used to prove existence of a safety margin above operating voltage is the AC high potential ground test. It applies a high AC voltage (typically, 65% of a voltage times twice the operating voltage plus 1000 volts) between windings and frame. Although this test does detect poor insulation condition, the high voltage can arc to ground, burning insulation and frame, and can also actually ca use failure during the test. It should never be applied to a motor with a low megger reading.DC rather than AC high potential tests are becoming popular because the test equipment is smaller and the low test current is less dangerous to people and does not create damage of its own. CLEANING AND DRYING WINDINGS Motors which have been flooded or which have low megger readings because of contamination by moisture, oil or conductive dust should be thoroughly cleaned and dried. The methods depend upon available equipment. A hot water hose and detergents are commonly used to remove dirt, oil, dust or salt concentrations from rotors, stators and connection boxes.After cleaning, the windings must be dried, commonly in a forced-draft oven. Time to obtain acceptable megger readings varies from a couple hours to a few days. BRUSH AND COMMUTATOR CARE Some maintenance people with many relatively trouble-free AC squirrel cage motors forget that brushes and commutators require more frequent routin e inspection and service. The result can be unnecessary failures between scheduled maintenance. Many factors are involved in brush and commutator problems. All generally involve brush sparking usually accompanied by chatter and often excessive wear or chipping.Sparking may result from poor commutator conditions or it may cause them. The degree of sparking should be determined by careful visual inspection. The illustrations shown in Fig. 5 are a useful guide. It is very important that you gauge the degree number as accurately as possible. The solution to the problem may well depend upon the accuracy of your answer since many motor, load, environmental and application conditions can cause sparking. It is also imperative that a remedy be determined as quickly as possible. Sparking generally feeds upon itself and becomes worse with time until serious damage results.Some of the causes are obvious and some are not. Some are constant and others intermittent. Therefore, eliminating brush sp arking, especially when it is a chronic or recurring problem, requires a thorough review of the motor and operating conditions. Always recheck for sparking after correcting one problem to see that it solved the total problem. Also remember that, after grinding the commutator and properly reseating the brushes, sparking will occur until the polished, brown surface reforms on the commutator. Figure 5. Degrees of Generator and Motor SparkingNOTE: Small sparks are yellow in colour, and the large sparks are white in colour. The white sparks, or blue-white sparks, are most detrimental to commutation (both brush and commutator). First consider external conditions that affect commutation. Frequent motor overloads, vibration and high humidity cause sparking. Extremely low humidity allows brushes to wear through the needed polished brown commutator surface film. Oil, paint, acid and other chemical vapours in the atmosphere contaminate brushes and the commutator surface. Look for obvious brush and brush holder deficiencies: 1.Be sure brushes are properly seated, move freely in the holders and are not too short. 2. The brush spring pressure must be equal on all brushes. 3. Be sure spring pressure is not too light or too high. Large motors with adjustable springs should be set at about 3 to 4 pounds per square inch of brush surface in contact with the commutators. 4. Remove dust that can cause a short between brush holders and frame. 5. Check lead connections to the brush holders. Loose connections cause overheating. Look for obvious commutator problems: 1. Any condition other than a polished, brown surface under the brushes indicates a problem.Severe sparking causes a rough blackened surface. An oil film, paint spray, chemical contamination and other abnormal conditions can cause a blackened or discolored surface and sparking. Streaking or grooving under only some brushes or flat and burned spots can result from a load mismatch and cause motor electrical problems. Grooved commutators should be removed from service. A brassy appearance shows excessive wear on the surface resulting from low humidity or wrong brush grade. 2. High mica or high or low commutator bars make the brushes jump, causing sparking. 3.Carbon dust, copper foil or other conductive dust in the slots between commutator bars causes shorting and sometimes sparking between bars. If correcting any obvious deficiencies does not eliminate sparking or noise, look to the less obvious possibilities: 1. If brushes were changed before the problem became apparent, check the grade of brushes. Weak brushes may chip. Soft, low abrasive brushes may allow a thick film to form. High friction or high abrasion brushes wear away the brown film, producing a brassy surface. If the problem appears only under one or more of the brushes, two different grades of brushes may have been installed.Generally, use only the brushes recommended by the motor manufacturer or a qualified brush expert. 2. The brush holder may have been reset improperly. If the boxes are more than 1/8†³ from the commutator, the brushes can jump or chip. Setting the brush holder off neutral causes sparking. Normally the brushes must be equally spaced around the commutator and must be parallel to the bars so all make contact with each bar at the same time. 3. An eccentric commutator causes sparking and may cause vibration. Normally, concentricity should be within . 001†³ on high speed, . 002†³ on medium speed and . 04†³ on slow speed motors. 4. Various electrical failures in the motor windings or connections manifest themselves in sparking and poor commutation. Look for shorts or opens in the armature circuit and for grounds, shorts or opens in the field winding circuits. A weak interpole circuit or large air gap also generate brush sparking.

Athabasca Pass Canadian National Historic Site Paper Research

Athabasca Pass Canadian National Historic Site - Research Paper Example The British Columbia side of the site is provincial crown land administered by the British Columbia Ministry of Forests† ("Athabasca pass national," ). Athabasca mean â€Å"where the reeds are† in Cree which is the description of the delta where Athabasca river enters into Athabasca lake. Apart from the exotic beauty that Athabasca Pass embraces, the site holds archaeological remains that include artifacts relating to the fur trade from the nineteenth century. The historical geographical importance of Athabasca pass relates to it being a link between the east and the west. The natives of this area have always used this land as a transportation route. Between 1811 and 1850, Athabaska Pass was an important trade route for fur. David Thompson first searched for this route in order to get around the barrier mounted by the Piegan Indians at Howse Pass. Until the mid 1850’s; both the British and American barters used this route for their commercial activities due to its strategic location on the Continental divide. Later on due to certain conflicts between the British and American traders, Hudson’s Bay Company which was a pioneer in the fur trade industry withdrew from the profession. This incident rendered the Athabasca Pass idle. However, later on in 1848, a new mail service emerged which started using this route. This new mail service used to bring mail from New York to Panama by steamboats and then transported these mails to t he Oregon Coast by another boat. This path made the mail service quite efficient. In 1855, the mail service suspended their use of this route, after which the pass was used occasionally. George Simpson, Governor of the Hudsons Bay Company, named the pond at the top of the pass as "Committees Punch Bowl" in 1824. In 1826, Botanist Thomas Drummond studied the diverse flora and fauna of this region for the first time. Later in 1827, a Scottish botanist named â€Å"David Douglas

Cause and effect Essay Example | Topics and Well Written Essays - 750 words - 1

Cause and effect - Essay Example There is something dark about the human psyche which even science cannot fully explain. It is a well-known fact that every person has a different level of endurance, and if pushed further than that the inner animal emerges and even the gentlest of human beings can commit the most heinous of sins, for instance, murder. Classical authors of time past have also tried to capture this facet of human personality in their writings. The concept of ‘The Other’ in The Picture of Dorian Grey and the foiling of Bertha and Jane in Jane Eyre are startling. These show very clearly that there is a part in our psyche which has not evolved over time; it has the instincts of a monster. It is that part which is taboo and which we hide from the polite society in fear of being rejected. Now the question is how masterfully you control that part of yourself. We cannot give it free reign, we cannot ignore it, so what do we do? As a result, a new genre of literature and movies has emerged: Gothic or Horror. Gothic or horror movies help us exercise our inner self without being obvious or hurting others. There is something about horror movies which makes one feel awed. I remember the first horror movie I saw was ‘Resident Evil’ when I was eleven years old. ... This made me really think about the real psyche of humans, later. When I read ‘The Lord of The Flies’, this feeling came back. In extreme circumstances, the luxury of our so called sophisticated exterior is shattered and we begin to think like animals. Horror movies make us relish the emotions of horror and terror. It is as if we are taking our shot of this other-worldly reality. The pleasure mixed with horror we feel does not mean that we enjoy doing this to others; it simply means that the boring and monotonous life is left behind and we feel as if we are with the protagonist racing through zombies, clashing swords with vampires and killing our enemies. Humans are emotional beings, who want an outlet to all the natural emotions which have to be felt to live a normal life, but are unable to because nothing extraordinary is happening in their lives and in this normal world. We try to escape from it all and feed our inner demons by watching horror movies or playing gory v ideo games. All the pounding, the blood and the struggle uses up our adrenaline and makes us more composed and controlled in our very day life. I have asked myself after growing up what it was about ‘Twilight’ that made me, for a short span of time, almost worship the idea of a vampire and werewolf? In real life a blood drinking fanged person, or a half-man, half-wolf would be far from sexy but would be downright ugly, disgusting and scary. Then I understood that it was my idea of an adventure, experiencing something powerful and terrifying which I would have been unable to achieve in real life, and it filled that part of my psyche which is called ‘The Other’. Hence, humans crave horror movies for various reasons, the most prominent being satiating the hidden beast

Affect on weight gain and sugar water on Mice Research Paper

Affect on weight gain and sugar water on Mice - Research Paper Example Overweight and obesity are interrelated terms for many health complications. Children and adolescents also fall under this category. Many health complications such as diabetes, cardiovascular disease, hypertension, breast, colon and prostate cancers and depression are associated with the obesity and overweight.. Obesity is caused due to the imbalance in the energy homeostasis. Many factors such as metabolic, environmental, cultural, socioeconomic, genetic and behavioral factors are associated with the obesity and overweight. The reason for the increase in the body weight was identified as increased carbohydrate intake mainly in the form of sugars. Carbohydrate intake increases the blood glucose and insulin levels. If simple carbohydrates are taken in the food, the production of glucose is very high and it increases the blood glucose level. Undigestable carbohydrates do not increase the blood glucose level as that of simple sugar and simple carbohydrates. This sort of hyperglycemic re sponse increases the carbohydrate oxidation and contributes to the body fat gain. (Malik, Schulze and Hu). The sudden changes in the blood glucose contribute to the variation in the postprandial glucose concentration. This finally affects the metabolism of the body and induces weight gain. Our body can store 300-500g of carbohydrates as glycogen in the human body and the rest are oxidized and converted into fat. The studies have confirmed that a 480g of oral carbohydrate load did not induce the fat oxidation in the young adults. (Saris). If the percentage of carbohydrate intake is very high then the increase in the body weight will be drastic. The increase in the body weight also leads to the risk of coronary heart disease and Type 2Diabetes mellitus. Obesity is generally caused by the difference in the energy homeostasis of food intake and daily physical activity. Obesity is the nutrition related problem in the developing and developed countries. To overcome obesity, many health gu idelines are focused such as increase in the physical activity and reducing the intake of foods containing sugar and fat. Sugar is a disaccharide molecule. Sucrose, maltose and lactose are compound sugars with the general formula C12H22O11 . (Saris). Sucrose is the common sugar used in our day to day life. Sucrose contains glucose and fructose. Sucrose is the most important dietary factor for weight gain. Readily digestible food have high glycemic index( GI) with higher post prandial blood glucose and insulin concentrations than the less digestible carbohydrates. Sugar containing foods have high glycemic index and increase the carbohydrate oxidation and contribute to body weight. (Saris). Similarly high fructose and galactose content increases the body weight. The galactose and fructose are used as sweeteners in the food and they increase the blood glucose concentration on ingestion. The sweet taste of the sugar is the main reason for the preference and intake of carbohydrate rich f ood. Diet induced obesity is caused by the conversion of carbohydrates into fat deposits in the white adipose tissue and the liver. (Lowndes et al.). The energy metabolism and carbohydrate and lipid metabolism are regulated by a complex network of signaling processes. High sucrose diet can induce the expression of the white adipose tissue and mRNA of liver Lipoprotein lipase enzyme. High sucrose diet is found to increase the risks of cancer. Pancreatic cancer is the most pre dominant cancer in this case. The diet that contains high concentration of sucrose and dextrin acts as the

Reagan's Part In Ending The Cold War Essay Example | Topics and Well Written Essays - 750 words

Reagan's Part In Ending The Cold War - Essay Example It is then a question of determinacy or of choice. The historian John Lewis Gaddis, in his book The Cold War, highlights the figure and role of Ronald Reagan as being the reason for the downfall of the USSR. Gaddis gives much attention to the character, personality, and beliefs of the former president. In his own estimation, Reagan’s personality led to his decision to abandon the policy of dà ©tente, one which had been a central one of the American government since the Nixon administration. â€Å"Reagan came to this position thorough faith, fear, and self-confidence. His faith was that democracy and capitalism would triumph over communism, a ‘temporary aberration which will one day,’ he predicted in 1975, ‘disappear from the earth because it is contrary to human nature’† (Gaddis 2005, p. 276). Reagan’s intended his own economic policies, specifically de-regulation and low taxes, to have an international appeal in contrast to the party-line Marxism of the Soviets. Reagan shrewdly sought to abolish nuclear weapons while also enacting a massive military build-up. â€Å"It followed that neither communism nor nuclear weapons should continue to exist, and yet dà ©tente was ensuring that both did† (Gaddis 2005, p. 217). This allowed him to gain support abroad and curtail any suspicions on the Right that he was going soft. According to Gaddis, Reagan suspected that the USSR had suffered ideologically in the eyes of the world. Reagan implemented the Strategic Defense Initiative, which â€Å"challenged the argument that vulnerability could provide security [and] exploited the Soviet Union’s backwardness in computer technology†¦Ã¢â‚¬  (Gaddis 2005, p. 226). Reagan’s policy of confronting the USSR while also leaving open the possibility of peace forced the Soviets to increase defense spending while already fighting in Afghanistan.

Description of Christo and Jeanne Claude`s Installation The Gates Essay

Description of Christo and Jeanne Claude`s Installation The Gates - Essay Example It is all about altering the space and thus altering the eye. ‘The Gates’ have a rare quality that combines an open invitation with an exciting sense of mystery at every step into it. The saffron clothe hung at each gate just like a half-curtain had a function of masking the view ahead, for a few moments, when a person passes through it (Christo and Jeanne Claude â€Å"The Gates†). The gates masked the panoramic view at each step but also revealed a new vision also at every step (Christo and Jeanne Claude â€Å"The Gates†). The saffron wardrobe in which Christo and Claude had dressed up the classic elegance of the park provided a contrast beyond comparisons so as to make the onlooker feel as if he/she was entering a surreal world (Christo and Jeanne Claude â€Å"The Gates†). The monotony of visual experience caused by the repetition of the gates has a purpose to serve. It hides the contours of the park and gives out a monolithic experience where even when a visitor walks miles and miles, she would feel she had not moved at all. By repeating the space and expanding it, thus the artists had manipulated time as well, by instilling a feeling of eternity. The equal distance that is kept between the gates is yet another artistic technique to enrich the feeling of infinity. The very material presence of the textile is suggestive of the time-limited nature of this work of art. It is evident to the visitor to this work of art that it is not going to last forever just like a painting or a sculpture. Yet it has a unique value as a spectacle, a value that a painting or a sculpture cannot command. It is the time-constraint that imparted it a value as a spectacle. The installation also offered the onlookers, a side view, from the road, which was equal to an outside v iew. From this viewpoint, the gates transformed into a neat row of big women legs clad in saffron skirts (Christo and Jeanne Claude â€Å"The Gates†).

Ethics Case Study Example | Topics and Well Written Essays - 1750 words

Ethics - Case Study Example The police officers of every nation are empowered to ensure the safety of their communities and to arrest people that they suspect of being criminals. This level of power, for some officers, gives them the facility to abuse the authority accorded them by enaging in corrupt activities. The issue of ensuring police accountability is probably one of the hardest to achieve for police leaders (Miller, 2010). This is because police officers are in the first place empowered to use coercive tactics when enforcing the law. The law enforcement profession, in contrast to other proffesions, has numerous opportunities for acts of corruption. Corrupt acts in the police profession include taking bribes, giving false witness against a suspect, or pilfering itmes from a scene of crime. There have also been many cases in the past of police officers misusing physically battering suspects to get quick albeit wrong confessions. Such acts are then hidden by coworkers. These are just some of the problems t hat are faced by police leaders. The challenges that many police organizations face at present could be categorized into three groups; as administrative, operational, and political issues (Kaariainen, Lintonen, Laitinen and Pollock, 2008). Operational challenges are basically focused on order maintenance and crime control police operations. These operations include controlling drug-trafficking, prosecuting organized crime, and gangs, violent crime, and controlling social disorder. It is in these areas where most corrupt practices such as the use of brutality and bribe taking are prevalent. Administrative challenges have to do with allocating resources, engineering the transfer of officers, defining service quality, and handling daily administrative issues. Police leaders have in the past dealt with challenges in the officially prescribed manner. This can affect the induction of new regulations that will positively affect the police force. The hierarchical structure which stipulates that all direction flows from the top down can actually stifle any efforts of ordinary officers to improve their departments. Political challenges have to do with being affected by the community’s political environment. There have been many instances in the past when police actions were compromised by the influence of owerful political players who interfered criminal investigations. Such realities put a lot of pressure on police leaders because they know that they can be adversely affected by refusing to accede to the requests of powerful politicians operating within their jurisdictions. Reasons why these Challenges Need to be Addressed in Light of the Organization’s Mission, Values and Culture Police corruption basically refers to any acts that contravene the very rules that police officers are expected to uphold. Police officers, like all other members of communities, have basic needs and wants. Some police officers simply enter the force in order to earn a good livi ng whle serving their communities. Morever, their idealistic views of what is right and what ois wrong might be negatively affected once they are exposed to the world of crime and discover that criminals actually make more money than they do. Once this point is reached, it takes an extremely dedicated officer to refuse the temptation of large bribes in order to allow criminal elements in the society to

Impact of Web Services Essay Example for Free

Impact of Web Services Essay Web services are self-contained, self-describing, and modular applications that can be published, located, and invoked across the Web. Web services Perform functions that can be anything from simple requests to complicated business Processes†. (http://webservices. xml. com/pub/a/ws/2001/04/04/webservices/index. html) We are the habitants of the 21st century. This is considered as the most innovative century of the world. Day-by-day innovations have made the world a global village. Everyday, new models of home appliances are introduced in the market, and not only home appliances but also everything is changing itself day to day. Even human beings have adjusted their lifestyles according to the modern era. In old days, people used different sources to communicate with each other. They would send telegrams telephoned their fellows. Slowly as their minds began to innovate, they produced new sources of communication. Through many gradual changes we produced and benefited many things. The human mind is very sharp because it can do any new if it is utilized in positive way. This mind had innovated many things. And today the most popular source of communication is the web service. This is also the effort of human’s sharp mind. The web service is the easiest way to communicate people through computer. This service has several benefits and loses. When this service was launched it became very popular and now through this service people have established their businesses. This service provides entertainment, information, professions and benefit people in several other ways. â€Å"The Colorado Department of Agriculture uses Web services to publish deer and elk tracking data, Jet Blue Airways Corp. uses them to process credit card transactions, and the state of New Mexico uses them for content management†. Enrique Castro through his article focuses on the future obstacles, which will be faced by the society and how will it affect the businesses around the world. â€Å"Assessing the future impact of Web services is at best an uncertain exercise from todays vantage point. There will be technical consequences, but perhaps the most profound will be its effect on society and business. What will be the effect on IT workers, especially those on developed economies who are? Concerned about off shoring? Will a 90% reduction in the cost of Enterprise Application Integration projects lead to more unemployment? Or will businesses decide to tackle more ambitious projects with the extra productivity? At the same time, as the technical hurdles to attain a certain level of functionality are diminished, comparatively, business Considerations rises in importance. This means programmers and IT workers will need to get more involved with the business aspects and business consequences of their tasks. The needs to build on business skills are a frequent theme in trade journals today. Jobs that require business skills and internal company business knowledge are much harder to outsource†. (Castro, 2003) Through these scholarly articles and scientific point of view, people who use web service regularly have a bad effect on their health. Using web service regularly and continuously is a health hazard. The rays of computer are so powerful that they can damage the eyes in many ways. It strongly affects the iris inside the eye. These rays damage the brain also. It has severe effects on the human health. Web Services have a great impact in our daily life. People who are known of the web’s Negative and positive aspects try to spread awareness about it. Professional people use web for their work but today the rising question is about the young generation. Is it? Doing the right jobs on the web or just using it for fun, entertainment? It is very necessary to tell the kids about the positive and negative aspects of the web. It is a source to promote awareness among people but nowadays people are misusing the web services in several ways. â€Å"The maturing of Web services and interoperability standards allow users to have access to a framework that enables them to access spatial data and applications from anywhere across the network, as was recently demonstrated in the Australian Spatial interoperability Demonstration Project (SIDP) project. This means that data can be obtained from point-of-truth custodians, avoiding duplication and enabling business continuity solutions, saving significant time and money and delivering better information products. Despite these obvious benefits, this approach highlights a number of issues around security, connectivity, privacy, licensing, etc. These need to be, and can be, dealt with effectively. However, sometimes such issues begin to lead lives of their own. They turn into myths that risk resonating with the decision-makers, hampering much needed Innovation. † (http://www. directionsmag. com/article. php? article_id=2011trv=1) Through different opinions, Web services are very helpful in businesses, media and in our daily life. It helps us in every field either it is networking, marketing or any other occupation it is a proved fact that without web services we cannot go further in any field. Analysts have analyzed that web services would create problems in the future because people would be using web services above requirement and they will be dependant of web services. Lastly, I would conclude that web services are a way to communicate people across the world. It is a very useful technological service. It provides us better information, entertainment and knowledgeable facts about the habitants of the world. Today many people are misusing it just for the sake of money and their entertainment. People have made web services a black-money earning source, but we should try to destroy the destructive minds that are providing a wrong impression of the web services to us. It is a common belief of our society that media and web services are very-beautifully playing their role in destroying the youngsters. Web services have negative impact too on the Society, but it does not mean that we start avoiding such a useful source of information.

Bespoke Form of Contracts: A Scourge or Necessity?

Bespoke Form of Contracts: A Scourge or Necessity? Chapter 1 Introduction Research Rationale The use of standard forms of contract, FIDIC Red book (Red Book Engineer/ employer designed Contractor executed) was introduced in the UAE during the late 80s and early 90s, more specifically on Dubai Municipality infrastructure projects by the Dubai Municipality, later been transformed to RTA in 2006. Ever since FIDIC based bespoke forms introduced in the UAE, it has been used extensively in the construction industry, the Red book based FIDIC forms are extensively used in different types varying from lump sum to re-measurement contracts by many large organizations. Every project is associated with risk and is inevitable and the impact is spread across the project. Whilst the intention to introduce a standard form of contract was to achieve a balance in terms of risk sharing between the parties, conversely at a later stage clients started amending the standard form of contracts to safe guard their interests. Many such bespoke versions did not achieve the intended purpose as it became one sided due to the alterations. The one sided contracts, in other words i.e. by drafting partial contracts to safe guard the employers risks and financial positions will have a tendency to impact the construction cost. If the risk is high, the cost increases proportionally (Mohamed Hartman, 2000, p 15) UAE as a country has high potential and growth compared to the neighboring Gulf countries in the recent years (2003 2008), which led to many fast track infrastructure and building projects, most of those are innovative, having ambitious aspirations to become international land marks, having the common feature of shorter durations. One of the main reasons for adopting fast track projects was to reduce the financial burdens (loans and repayment period) and to minimize the risk for escalation due to the construction boom in the region. Also in a raising market, the cost of the construction was proportional to the duration of the project as the contractors were including the risk for escalation in their bids. A few examples for such land mark projects with shorter duration captured the attention are Burj Khalifa tower, Dubai Metro, Palm Island and Dubai Mall. The multinational construction interface between the parties and culture stipulated the importance of using standard forms of construction contracts in the UAE, one of the main reasons to use standard forms of contracts are the familiarity among the parties, which has been used across many developments worldwide, even practiced at courts, assumed to be understood by parties, the risks are apportioned in a balance way and understood by even the stake holders, reduced legal and construction cost. As mentioned above, one of such standard form of contract, FIDIC 1987 4th edition red book was introduced by Dubai Municipality in early 90s with amendments to the original form (bespoke version is called as Dubai Municipality general conditions of Contract), later been followed by many public and private sector clients in UAE. Many such amendments in the creation of bespoke versions of FIDIC forms have defeated the intended purpose of achieving a balanced version of contract By the mid of 2006, many clients started using bespoke versions of new FIDIC i.e. FIDIC 99 Contracts, however there is a significant difference between these two forms (FIDIC 1999 FIDIC 1987) of contracts in many areas. Like any other place in the world, the competitions in the construction industry among the contractors are very high in UAE also. Many clients in the region, whilst using open or selective tendering (as they invite tenders from their own tender pool), before and after the current economic crisis, do have the habit of awarding the works to the lowest bidder. In order to overcome the competition in the market, the contractors at times started under quoting the works, were trying to recover through variation and claims at a later stage. This situation resulted in arguments and disputes due to the wrong interpretation of the forms of contract used by different parties, in addition, the unbalanced and void bespoke versions contributed much to these kinds of disputes. Many such disputes were revolving around the poor interpretation and understanding of the variations clauses, leading to claims and disputes on fast track projects. The intended purpose of this dissertation is to identify The essential clauses needed to administer a contract The importance of making right interpretations while using contracts An overview of the bespoke versions of contracts Research Methodology A detailed analysis of Variation clause in Nakheel Conditions of Contract ( bespoke FIDIC 1987) and the possible interpretations by various parties to the contract, briefly stating the difference between 1999 1987 based forms clauses that relates to variation and varied work clauses. Identify the potential difference between the two bespoke versions i.e. FIDIC 1999 1987 4th edition Nakheel Conditions of Contract on major clauses. A case study on a dispute from ALDARs Conditions of Contract (bespoke of FIDIC 1999) on variations while using the bespoke versions of contract Proposed study chapters The intended study focus on the meaning of construction contracts, their existence and the different forms of contracts. The literature review is covered in the first four Chapters, Chapter 2 covers the use of different forms of FIDIC contracts, including a brief history of their start in the UAE, Chapter 3 focus on the essential clauses needed for the administration of any forms of Construction contracts, Chapter 4 an analysis of Nakheels conditions of contract (bespoke FIDIC 1987 4th edition) variation clause, the possible interpretations by different parties to the Contract, Chapter 5 a comparison between Two bespoke forms of Nakheels Conditions of contract (FIDIC 99 and FIDIC 87 4th edition) on major clauses, Chapter 6 a survey to identify whether the employers achieved the intended purpose by using bespoke versions, Chapter 7 analysis of the data collected ,chapter 8 recommendation. An overview of the construction Contracts Construction contracts are generally classified as Oral (when the act will not apply) or written (if the other criteria are met, the act applies). The form of written contracts are again classified into i. A simple exchange of correspondences; ii. A tailor made written agreement; iii. A standard form such as JCT,Fidic etc; iv. Standard terms and conditions of the business. Contract in broader term is defined or expressed as conformity between two or more person i.e individuals, businesses, organizations or government agencies to carryout, or to abstain from doing things in exchange for something of value. Contracts can be oral or written, using formal or informal terms. If one party to the contract fails to live up to its part of the bargain, there shall be a breach and certain remedies for solving this is available. The expressions of the contract who, what, where, when, and how of the contract describe the binding promises of each party to the contract. In other words the significance of the agreement becomes important only when a breach occurs by the counterpart and it becomes necessary to protect the right of the other party (http://law.freeadvice.com/general_practice/contract_law/contract_agreement.htm) and the breach of contract is recognized by the common law and the remedies are available as well. On the other hand, the strongest contract, in terms of enforceability, shall have an offer, acceptance with considerations for the exchange, the terms of such an agreement shall be without ambiguity, and is signed by the parties to the contract who has the proper capacity to enter into the contract. Weaker contracts can be classified as verbal agreements or contracts agreed by parties in direct violation of state or federal laws of the country. There are several aspects related to valid contracts; in fact, an entire course in law school is often devoted to contract law (http://www.wisegeek.com/what-is-a-contract.htm). John Adriaanse (2007) quoting Lord Diplock who classified construction contract as â€Å" the sale of goods, work and labor for a lump sum price payable by installments as the goods are delivered and the work done. Decisions have to be made from time to time about such essential matters as the marking of variation orders, the expenditure of provisional and prime cost sums and the extension of time for carrying out the work under the contract†. He also stated that â€Å"a construction contract is best described as a complex web of competing interests†. At the same time Charles.S. Philip (1999) defining contracts as â€Å"binding agreement between two or more persons or parties construction contracts are defined as agreements, oral or written, executed between Clients and Contractors for construction / maintenance work done for compensation†. In another definition â€Å"we must understand that a construction contract is merely a set of criteria, or expectations, t hat bind the contracting parties† (Gilbreath, 1992) The basic elements of a contract are an offer, acceptance of the offer with considerations. This can even be described as concurrence of wills or ad idem or meeting of the minds of two or more parties (http://www.alway-associates.co.uk/legal-update/article.asp?id=165).Consideration, on the other hand, makes sure that e that something is exchanged. In certain situations, the law requires the consideration to be adequate, which is, a relatively reasonable price, or ostensible, where even a Dirham will do. Contracts may or may not be enforceable by law. The good example is; the agreement between the parent and child cannot be enforceable by law whereas the agreement for a loan probably enforceable by law. On the other hand whether a contract is enforceable by law or not depends on many factors, the primary and most important factor being whether the parties to contract anticipated / intended the contract to be legally enforceable or not. Most of the construction contracts are bilateral contracts, some cases the unilateral contracts becomes bilateral with considerations. Contracts can be bilateral or unilateral. In a bilateral contract, each part makes promise or promises to the other party. A good example is while selling a home, the buyer promises to pay the seller AED 1 Million in return the seller agree / promise to deliver the title of such property. Where as in a unilateral contract only one party to the contract make the promise. A good example is the reward contract. X promise to pay a reward to Y if Y find Xs stolen car. Here Y is not obliged to find Xs stolen car, but X is obliged to pay the reward to Y only if Y finds Xs car. The consideration for the agreement is Ys trust on Xs promise or Y giving up his legal right to anything he wanted at the time he was in the process of finding of the car. Here, conditions precedent to Xs obligation to pay is the finding of the car, although this is not a legal condition precedent as technically no binding contract has arisen until the time car is found (because Y hasnt agreed / accepted Xs offer until he find the car, referring back to the basis of contract as it requires offer, acceptance and considerations), the terminology â€Å"condition precedent† is used in contract law to establish a condition of promise in an agreement. For example, If Y has promised to X to find the car, and X has promised to pay Y when the car was found, Xs offer has been considered as a condition attached to it, and an offer and acceptance have been occurred. This is an incident in which a condition precedent attached to a bilateral contract. In the construction industry, the significance of having a balanced contract agreement has become essential to avoid disputes and to facilitate a smooth administration during the construction period. According to Lord Lathams report 1994, â€Å"constructing the team†, construction is a very unique process, the construction industry is different than the manufacturing and other industries, each project is unique with its nature and conditions, having heterogeneous conditions and situations, however definition of Latham for contracts not limited here, but include the design activities, advise and other legislations (Adriaanse 2007) which specify many details that a construction contract should take care of. Chapter 2 The Importance of using Standard forms of Contract 2.1 Introduction The adversarial nature ([Cheung et al., 2006] and [Cheung and Yiu, 2007]) and inborn risks (El-Sayegh, 2008) of the construction industry contributes to the speedy developments of construction disputes. Construction disputes are originated by many sources (Cheng et al., 2009). One of the main sources is the lack of understanding on the Contracts. Deprived interpretation and poor understanding of the construction contracts make the contracts clauses ([Broome and Hayes, 1997], [Cutts, 2004] and [Styllis, 2005]) and legalese ([Cutts, 2004] and [Candlin et al., 2002]), which results in differences between the parties to the contract on their legal rights and responsibilities. It is to be noted that this statement is justified in a study conducted by Mohamad and Zulkifli (2006), where majority of the contractors reported about the problems in understanding the contract documents. It is to be concluded that contractors need to be well versed in the interpretation and understanding of claus es stated in contracts. Dispute resolution methods at the early stages of disputes are the soft-skill resolution technique, i.e. avoidance (White, 2002), which offers a practical approach to prevent the predictability of conflicts that may occur in a project by understanding the form of contract used. The main objective of dispute avoidance technique is to promote teamwork and to create a harmonious atmosphere (Cheung, 1999). Thus, a proper appreciation of the construction contracts to the stakeholders will prevent a dispute from rotting, although a total elimination may be impossible. The importance of this chapter is to make a improved insight into the need for clarity of contract documents. Furthermore, it will assist contract drafters and experts review and clarify the clauses of the contract form in an understanding way to the parties. After the parties understand and consent to the clauses stated in the contract, the parties would recognize their obligations and contractual rights as required in the contract. 2.2 The need for contract clarity The need for this research comes up out of many conflicts identified in the construction industry due to the usage of different versions of contracts with amendments. A good example is, the senior officials of a leading developer in Dubai alleged that false ceiling collapsed and burst the pipes above the false ceiling at the buildings were related to the supervision problem and lack of access to the project site by the engineers (Developer Eyes ‘supervision authority2007). The engineers were not allowed on site due to some health and safety construction complications at certain times. This resulted inadequate supervision for the works. The problem heated up although the standard contract form clearly points out that the engineer, as being responsible for the overall supervision and direction of the project. Additionally, the Engineers representatives had the right of access to the works and construction site of the contractor (Clause 23 of bespoke Form). An explanation for this dispute was, contractor misinterpreted the conditions of contract and also failed to understand the legal obligations outlined in the contract. Thus, the question of clarity of contract conditions in the contract must be resolved. In addition, the court usually try to find out the intentions of contracting parties using plain, ordinary and popular meanings of the words. Scott vs Wawanesa Mutual Insurance Company brought out the clarity issue to the court attention (1994). The judge held that if the language of an insurance contract is ambiguous, the contra proferentem doctrine applies, that is the rule against the party who impose the inclusion of the ambiguous clause in the contract. On the other hand, if the wordings are unambiguous, the courts would not give any different meaning from what is expressed in its clear terms, unless the contract is highly unfair or hold an effect contrary to the intention of the parties (Duhaime, 2007 Duhaime, L., 2007. Part 7: interpretation of previous termcontracts.next term Duhaime Law, Victoria, Retrieved 22 May 2008, from .Duhaime, 2007). Thus, clarity of contract clauses is very important for the construction industry too. This shows the importance of understanding the c ontract by the contracting parties. Besides, the legalese takes place in the contract. The use of highly formal and technical language in legal documents disturbs interpretation (Feinman, 2003). Legal drafters made most damage by shrouding the mysteries of contracts with complex language and technical legal terms (Cutts, 2004). The deficiencies of legalese are mainly due to the unnecessary length and complexity. Sometimes, there are more serious errors that go unnoticed (Hill, 2001) because the interpretation of the contract clause was not actually written or interpreted in the contract (Thomas et al., 1994). Legalese would result the contracting parties fail to appreciate the contractual rights and obligations in a project (Semple et al., 1994). In the end, it shatters the working atmosphere of the project (Wang and Yang, 2005), resulting claims and delay to the project delivery. 2.3. Understanding the importance of standard form Construction contracts are well written agreements duly signed by the parties to the contract to define their contractual positions, relationships and obligations (Zaghloul and Hartman, 2003). The conditions of the contract are critical to ensure that the parties are put up by rules and regulations (Semple et al., 1994). The reduced understanding of the construction contract usually lead to construction disputes, as highlighted by many researches such as ([Thomas et al., 1994], [Semple et al., 1994], [Broome and Hayes, 1997] and [Mohamad and Zulkifli, 2006]). It is simply because of the reason that the parties could not achieve their contractual expectations (Harmon, 2003). Dubai Municipalitys be spoke forms of contract was followed and amended by various developers in the UAE industry. The origin of the contract can be traced to FIDIC Red Book 1987 standard form of contract. It had several amendments and revisions over the years by many developers and private sector clients in the UAE. The latest version of this form of contract was formulated in 2001 (Dr.Sam, 2004). The old-fashioned language used in it makes it difficult to understand and make the right interpretations. This is mainly due to lack of clarity and use of legalese in the contract clauses. Table 1 and Table 2 give a summary of clarity and legalese problems identified in the contract clauses of this Form. 2.4 History of FIDIC and other Standard forms of Contracts used in UAE Industry The most brilliant designs for any civil engineering or building project would remain in the documents and paper unless turned into reality by operations. This transaction process requires i.e. from the design to the reality requires the selection of the contract that reflects the aspirations of the parties as well as the demands of the successful project. The essential skills required for a Contract Administrator is the selection and management of proper form of contract and for each project, both the key criteria needed to be considered and risks should be identified and allocated, before the selection of the proper form of contract. This can be done from a range of standard forms of contract. In the UAE, the FIDIC form of contract (red book) was introduced in the early 90s for the infrastructure projects by Dubai Municipality, later been followed by many major clients such as Emmar, Nakheel and Damac. The standard form of contract identifies the roles and responsibilities of the parties, their agrents and provides rules to protect direct parties from doing wrong. The selection of the form of contracts depends on various criteria such as the responsibility and position of the parties involved in the contract. For example, factors such as , magnitude and nature of the works, procurement method (Lump sum, Measurement, Cost reimbursement), Design responsibility ( whether by the Employer, Part by the contractor or fully by the Contractor), roles and relationships (Client, Contractor, Design team and Specialists), the type of cost control document used (such as bill of quantities, schedule of rates, priced specification or contract sum analysis),Payment method (stage, time rela ted, turnkey) and Time (Open, fixed, acceleration and Damages). (Martin Brook, third edition, p 33-44) The various such forms of contracts available are JCT written by the Joint Contract Tribunal, NEC New engineering contract, a form recommended by Michal Lathams report (1994) for the use of both public and private sector clients because of its flexibility and written in simple English, ICE provided by the Institution of Civil Engineers, GC/Works/1 for Government Contracts, ACA Project Partnering Contract- PPC 2000, FIDIC..etc. A brief history of the FIDIC form of contract along with available forms are described below as the dissertation is focused on the FIDIC, the most commonly used for both building and Civil Engineering projects in the UAE. The Fà ©dà ©ration Internationale des Ingà ©nieurs-Conseils (â€Å"FIDIC†) organisation was founded in 1913 by France, Belgium and Switzerland. The UK joined only in 1949. The first edition of the Conditions of Contract (International) for Works of Civil Engineering Construction was published in August 1957 having been prepared on behalf of FIDIC and the Fà ©dà ©ration Internationale des Bà ¢timent et des Travaux Publics (FIBTP). The form of the early FIDIC contracts was prepared in line with the fourth edition of the ICE Conditions of contract. One difference with the initially published FIDIC contract was that they were based on the design being provided by the Employer or his Engineer to the Contractor. It therefore became best suited for various civil engineering as well as to various types of infrastructure projects such as roads, bridges, dams, tunnels and utility works such as water, sewerage etc. At the same time it was not so suited for contracts having major items of plant that were manufactured away from site. This led to thought of having the â€Å"Yellow Book† (the traditional one is known as the â€Å"Red Book† it was called as Red book because of the red color of the cover page) published in 1963 by FIDIC for mechanical and electrical works. This had the provisions for testing and commissioning which was more appropriate for the manufacture and installation of plant. The revised (second edition) was published in 1980. The revised editions of both Red book and yellow books FIDIC was published in 1987. A most important feature of the revised edition of Red Book (or â€Å"Old Red Book†)was provision for the Engineer to act impartially while giving a decision or in any action which affect the rights and obligations of the parties, whereas the previous versions assumed this implicitly. Although this talk concentrates on the new FIDIC forms, it should be remembered that the Old Red Book remains the contract of choice throughout much of the Middle East, particularly the UAE. A new form of contract was published (known as the â€Å"Orange Book†) in 1995 for the use on projects procured as design and build or turnkey, dispensing with the Engineer, providing for an â€Å"Employers Representative† who, while determining the value, costs or extensions of times need to: â€Å"determine the matter fairly, reasonably and in accordance with the Contract†. However, in 1999 FIDIC published new versions of the Red and Yellow books together with a Green and silver Books called as the short form of contract and turnkey contracts respectively. One of the significant differences between the 1999 edition and 1987 4th edition was the arguably diminishing role of the Engineer; a fair interpretation is making the Engineer as an assistant to the Employer. The other differences between these two versions will be discussed in the following chapters of this dissertation. Chapter 3 3.1 The important clauses and terminologies needed contract administration and a comparison with the bespoke version selected for the dissertation work During the process of making bespoke versions of contracts by amending the articles of the standard forms shall be done with extreme care as they run the risk of damaging the consistency as well as the integrity of the contract and the other contract related documents. Most of the standard conditions of contracts are developed over many years and been highly complex to deal with the unforeseen problems and legal decisions including statute law and an ever changing world. The contract must state clearly the documents that are having the status of the contractual documents, following are the documents that shall be considered as the contract documents. i. The signed agreement ii. Tender iii. General and particular conditions of contract iv. Drawings v. Bills of Quantities vi. Specification vii. Schedules viii. Program There are certain clauses required in the contract to facilitate the smooth administration of any contracts. The following are the commonly found and essential clauses required in construction contracts between the employer and the contractor irrespective of the forms and types of contracts. A detailed analysis with its importance is analyzed in this chapter for the dissertation purpose. Possession the date by which the employer shall provide possession to the contractor of the site to enable the work to begin, In FIDIC 1987, the commencement of work is described under the clause 41.1. The commencement shall be given with in the period agreed in the appendix to tender and failure to provide possession to the site within a reasonable time is interpretted as the breach from the employer.(CEM course material, Construction Law, chapter..). Under FIDIC 1987, the employer will, with the Engineers notice to commence the works, give to the Contractor the possession of the site (E.C Corbett, FIDIC 4th Legal Guide, p 238-239). Failure to give possession is dealt under clause 42.1, under such circumstances, the Engineer shall, after due consultation with Employer and Contractor determine Contractors entitlement for extension of time and also the associated cost, which shall be added to the Contract price, notify the Contractor with copy to the Employer (E.C Corbett, FIDIC 4th Legal Guide, p 238-239). Hence this clause is essential while drafting an agreement or contract for the administration. Completion The date, by which the contractor shall have the obligation to finish the work, this can be extended under various provisions if the employer or his contract administrator / engineer grant extension of time. Under FIDIC 1987, upon substantial completion of the work, the Contractor serve notice to the Engineer with copy to the Employer for the taking over certificate, and if the work in the view of the Engineer is substantially completed, issue a taking over certificate with in 21days. This is a very essential clause in any form of contract as in the absence of a completion date in the contract; the contractor shall be required to finish the work only within a reasonable time(ref: John Uff..). Non completion this clause shall deal with the situations when the contractor fails to complete the work by the agreed completion date or the extended completion date. If the work is not completed within the specified time, due to any reasons that the contractor is not liable or any concurrent delays, the contractor get the benefit of having an extension time with associated costs. However for Contractors own delay, the contractor shall not be entitled for the entitled for any extension of time, the remedy available in the contract is to make payment to the employer as liquidated damages or penalty as mentioned in the contract. Hence it is very essential to have a non-completion clause in agreements and contracts. Liquidated damages / Penalty Liquidated damages are usually amount is fixed and genuine pre-estimate of the loss in cases of breach, easy to calculate on building or commercial projects, however not easy on infrastructure projects. Whereas penalty is also a fixed amount, the contractor needs to pay this if a breach occurs. However in UAE, the term penalty is applicable as the same is followed in civil court. Whereas, under the English Law, Liquidated damages are applicable, if the sum mentioned in the appendix to tender is penalty and not the liquidated damages, the Contractor under the English law can challenge it, however under the UAE Law Civil code, Article,.. the penalty is applicable. Most of the Countries penalties are not acceptable. Refer, for example, a few leading cases on penalties, Dunlop Pneumatic Tyre Company Ltd v New Garage and Motor Company Ltd [1915] AC 79, 86-87, where the House of Lords recognized the principles on how to decide a damage clause that is actually a penalty and thereby unenforceable. â€Å" This case was cited by the High Court of Australia in Ringrow Pty Ltd v BP Australia Pty Ltd [2005] HCA 71, section 12, and by the Supreme Court of Ireland in ODonnell v Truck and Machinery Sales Limited 1998 4 IR 191. The Supreme Court of Canada has adapted a similar approach in Elsley v. J.G. Collins Ins Agencies, [1978] 2 S.C.R. 916, 946, and does not allow for any recov ­ery of an amount exceeding the actual damage† (J.Frank McKenna (2008) Critical Path. Reed Smith, p1-6). Hence this clause is essential in a contract or agreement. Defects liability- The defects are to be rectified with the period mentioned in the contract. Failure to rectify the defects within a reasonable time will enable the employer to engage a third party to do the work and deduct the amount from the contract sum. Under FIDIC 4th edition, clause 62 deals with the defects liability period. The issuance of the defects liability certificates signals the completion of the Contract and under FIDIC form, such a certificate shall be issued within 28days from the completion of Defects liability period, in both forms of FIDIC 99 as well as in 87 including the bespoke versions, the defects liability period shall not be extended beyond 2 years from the taking over certificate (E.C Corbett, FIDIC 4th Legal Guide, p391-392). Variations any variations should be authorized by the employer before the contractor is entitled for the payment. Variations are common to traditional procurement path than the Design and Build system (Ashworth, 1998). In construction due to the complexity of construction works it is almost impossible to complete a project without changes to the plans or the construction process itself however good and the complete the design details are at the start of the project. Baxendale and Schofield (1996) define variation as any change to the basis on which the original contract was signed. Construction plans are formed form of designs, drawings, quantities and specifications earmarked for a specific construction site and Variations are imminent in any construction project due to various reasons from finance, design, aesthetic, geotechnical, geological, weather conditions to feasibility of construction. Hence it is essential to have a provision to instruct and ev
