Financial Management - Essay Example The company is deemed to be the third largest retailer with respect to the amount of revenue that it produces (Potter, 2011; Deloitte, 2010). To examine and analyze the financial performance of the company, the ratio analysis technique needs to be used. Ratio analysis is a technique which uses a set of different financial measures known as financial ratios, in order to analyze the financial performance of a company. These financial ratios of the company would be compared with its prior year ratios to understand whether there is any improvement in the performance of the company (Shim et al, 2000). The financial ratios for Tesco plc are as follows: Ratios 2010 2009 Liquidity Ratios Current ratio 0.73 : 1 0.75 : 1 Quick ratio 0.44 : 1 0.61 : 1 Gearing Ratios Gross debt-equity ratio 74.9% 109.6% Net interest cover 3.1 times 7 times Profitability Ratios Gross Profit Margin 8.22% 7.76% Net Profit Margin 4.1% 3.99% Investment ratios Earnings per share 29.33 cents 27.50 cents (Annual Report, Tesco plc, 2011) . Liquidity Ratios evaluate a company’s ability to pay off their debts when they fall due. Basically it gives a basic picture of a running position of a company. Current ratio illustrates a company’s ability to pay off its short term obligation/ current liabilities (amount due within 12 months time) with the current assets that it holds whilst the quick and the cash ratio illustrates a company’s ability to pay off their debts with the most liquid assets and cash respectively. Current ratios on the other hand analyze a company’s ability to pay off their respective debts/liabilities through their most liquid (easily converted to cash) assets. The ratios in the above table indicate that the liquidity position of the company has worsened in 2010 as compared to 2009; both the current and the quick ratios have deteriorated over the year. The current ratio has fallen from being 0.75:1 in 2010 to 0.73:1 in 2009. The quick ratio has also fallen f rom being 0.61:1 in 2010 to 0.44:1 in 2009. This should be a concern for the company as the liquidity ratios are a measure of company’s subtleness and long term sustainability. With the help of the profitability ratio, a company can ascertain the increase/decrease in the level of costs, revenues and profits over any given period of time. These ratios help in ascertaining the company’s performance with respect to the profits that the company/organization has generated. Gross Profit Margin/Net Profit Margin ratios help in ascertaining a company’s gross profit/net profit with respect to the revenue that the company has generated; this ratio helps in understanding the changing trends of the operational costs within any particular period of time. Both the Gross Profit and the Net Profit margin ratios have improved for the company over the one year concerned. This is a good sign for the company with respect to its growth, the company’s gross profit margin has i mproved from being 7.76% in 2009 to 8.22% in 2010, this is both because of the fact the company has increased its sales revenue and it has controlled its cost as well. The net profit margin has also increased from being 3.99% in 2009 to 4.1% in 2010, although the change is not a huge one but still for a large company like Tesco plc, this change is worth noting as it has increased the company’

The Madness of John Brown Essay Example for Free

The Madness of John Brown Essay Historians are not the only ones that can elucidate history. History is a extensive puzzle that can be solved by anyone who has an educated diploma on certain subjects. Historians are the main disposition to solve the uncertainty of history with their useful, quality skills of making theories to conjoin loose ends of history, motivation of repeated research, and their undying love to learn new history, but a psychologist can solve history too with their forte. Even though it may seem absurd to believe that this occupation who assesses a mans personality to solve problems; a psychologist can solve an dead mans prospective in life. A letter is a common communication device in the old days and can be read by anyone. A historian would try to find key words in the letter to guesstimate the situation, but a psychologist knowing the mysteries of attitudes and behaviors of people would look at double meanings in passages. Two perceptions are better than one and knowing the true motivation of a persons mind than their careless actions can give an different outlook of a case. Other specialists can help historians find the gist of John Brown rationale of being insane in the terms of slavery and why he killed five men in the open. Although John Brown never underwent a psychological examination about his childhood, he had left a letter with important information of his childhood into a story. Psychoanalytic insight has helped to reveal some of Johns most intense personal conflicts from this letter; his ambivalence toward his fathers strict discipline, the paradox of Browns struggle to internalize and accept his fathers authority in order to become independent himself, and his main concern with property and pets as a means of defining his independence. This ambivalent father-son relationship suggests that Browns intense life-long identification with black slaves might well have sprung from the struggle he experienced with paternal discipline. Helping slaves was ultimately a means of helping himself without consciously recognizing the source of his emotions and convictions. He could have channel the repressed hostility toward his father toward the slaveholders. In conclusion, psychologist has added the tool of psychoanalysis in the study of history. This tool has helped historians to go beyond rational motives in understanding people who have changed society and history in either a good or bad way. History has somewhat gotten more clearer and truthful thanks to psychologists.

Source Of Mechanical Energy Engineering Essay

Source Of Mechanical Energy Engineering Essay Introduction Electricity is a basic part of nature and it is one of our most widely used forms of energy. It is a secondary energy source that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. Many cities and towns were built alongside waterfalls (a primary source of mechanical energy) that turned water wheels to perform work. Electricity consists of the presence of electric charges, as well as the flow of those charges. There are three forms of electricity. One form is static electricity, which is the presence of either positive (+) or negative (à ¢Ã‹â€ Ã¢â‚¬â„¢) electric charges in or on an object, usually a non-conducting material. The second form of electricity is the flow or movement of free electrons through a conducting material, such as a metal wire, toward an area of positive electric charges Electricity appears in two forms: alternating current (AC) and direct current (DC). Direct current does not change directions the electron flow is always from the negative pole to the positive pole although as we mentioned before, the electrons themselves dont really move, its the holes that are created that move. Direct current is almost always what is used inside of electronic devices to power the various internal components, but it is a harmful thing in audio signals, which are alternating current. Alternating current (AC) electricity is the type of electricity commonly used in homes and businesses throughout the world. While direct current (DC) electricity flows in one direction through a wire, AC electricity alternates its direction in a back-and-forth motion. The direction alternates between 50 and 60 times per second, depending on the electrical system of the country. AC electricity is created by an AC electric generator, which determines the frequency. What is special about AC electricity is that the voltage can be readily changed, thus making it more suitable for long-distance transmission than DC electricity. But also, AC can employ capacitors and inductors in electronic circuitry, allowing for a wide range of applications. Direct current or DC electricity is the continuous movement of electrons from an area of negative (à ¢Ã‹â€ Ã¢â‚¬â„¢) charges to an area of positive (+) charges through a conducting material such as a metal wire. Whereas static electricity sparks consist of the sudden movement of electrons from a negative to positive surface, DC electricity is the continuous movement of the electrons through a wire. A DC circuit is necessary to allow the current or steam of electrons to flow. Such a circuit consists of a source of electrical energy (such as a battery) and a conducting wire running from the positive end of the source to the negative terminal. Electrical devices may be included in the circuit. DC electricity in a circuit consists of voltage, current and resistance. The flow of DC electricity is similar to the flow of water through a hose. Electrical Wiring Electrical wiring system is a network of electrical conductors for carrying electrical current to the electrical equipment involved. This method is related to the wiring system for buildings in Malaysia. In Malaysia, the electric wiring system is subject to the rules established by the Energy Commission as provided under the Electricity Supply Act 1990, Electricity Regulations 1994, the MS IEC 60364:2003 Standard Electrical Installations of Building, MS 1936:2006 Electrical Installations of Building Guide To MS IEC 60364 and the MS 1979:2007 Electrical Installation of Building Code of Practice. Wiring systems used in Malaysia is very similar to the electrical wiring standards used by the United Kingdom but by the standards of the wire conductor already changed. NEW TOWN DEVELOPMENT SDN BHD PROJECT The high-rise building electrical system For The New Town Development Sdn Bhd project, this building was a high-rise commercial building. The building comprises of 4 storey basement parking and 7 storey shopping complex and the rest are offices lot. So, for the electrical installation should at every floor there were a number of electrical panels to serve all the lighting and power requirements on that floor including the lighting, switched socket outlets, toilet exhaust fans and anything else. Some areas of the office used an open floor office systems so under floor trunking was also used here. Besides, a few of the panel were located inside the riser room of each floor. However, since each was a large area some panels needed to be located at the office area. Wiring directly from the electrical riser would be unnecessarily too long. Therefore, the electrical consultant locates these electrical panels along the corridors throughout the building. The design architect was requested to provide small rooms to house the panel. Alternatively, small electrical cabinets with lockable doors and sufficient work access and ventilation would be acceptable. If the planned building is very high example like 40 storey office building or in cases where heavy loads are located at higher levels of the building, it may be necessary to provide substations at the higher levels of the building. For the 40-storey office building, an 11/415 kV substation may be necessary at one of the upper floor. It may be located at twentieth floor, for example. All the electrical substation room spaces as explained earlier will then need to be provided except the authoritys electrical rooms. The floors of this substation would then need to be specifically designed by the appointed structural consultants to handle the loads of all the substation equipment. Based on the structures and other factors was related. We propose the installation of electricity for this building using the radial system and ring main system. Because its easier to maintain and simple system for the design and construction. In addition, using the rising main distribution system is important because the building is more than 5 levels. So, to distribute electric power at every level is appropriate to use the rising main for the building. Basement A basement is one or more floors of a building that are either completely or partially below the ground floor. Basements are typically used as a utility space for a building where such items as the furnace, water heater, breaker panel or fuse box, car park, and air-conditioning system are located; so also are amenities such as the electrical distribution system, and cable television distribution point. In British English the word basement is used for underground floors of, for example, department stores but is used for a space below the ground floor of a house only when it is habitable, with windows and (usually) its own access. The word cellar is used to apply to any such large underground room. Subcellar is a cellar that lies further underneath. Based on the planned building project, the level of 1st to 4th is the basement. In part this is a car park. Therefore, we recommend the installation of electricity in the area using ring system. Ring system is ideal because in this part do not use electrical appliances and many others. Basement car parks.jpg Basement pendlehill1.jpg Basement Ring Main System in Basement A ring main wiring circuit is the alternative to a radial wiring circuit. In a radial wiring circuit, the wiring starts at the circuit breaker and connects to each device on the circuit (fans, outlets, lamps, etc) in turn. When it reaches the last device, the wiring simply ends. Ring main wiring goes one step further instead of ending the wiring at the last device; it pulls more wiring back from the last device to the circuit breaker, completing a loop. Ring main wiring is required in some places, and illegal in others. The main advantage to a ring main system is smaller wiring. Since each device on the ring has two hot wires connecting it to the circuit breaker (one on each side of the loop), smaller wiring can be used to safely carry the electric current. Smaller wire is both cheaper and easier to work with. It bends more easily, can be pulled around corners with less effort, and is easier to fit into the screws and connectors you need to attach it to. One other advantage is wiring distance. Wire has some small amount of resistance, and the longer the wire goes to reach the device it is powering, the more resistance it has. This results in a voltage drop over the length of the wire run (by Ohms Law), which could affect the operation of your electrical devices if it drops too low. The maximum distance from the circuit breaker around the ring is the midpoint of the ring, while the maximum distance in a radial circuit is the end of the chain. In this manner, the ring setup effectively cuts the distance to the farthest device in half. The radial system does have one advantage over ring main. If a break were to occur somewhere in the wiring loop of a ring main system, you wouldnt know it. Everything would still function normally because it is still powered from one end. However, this means that if you took advantage of the ability to run smaller wiring (and everyone does), your wire is now undersized for the current it is expected to handle because the system is no longer powered from two wires, only one. This can result in overheating of the wires, which in turn breaks down the insulation and can start a fire. In electricity supply, a ring final circuit or ring circuit (informally also ring main or just ring) is an electrical wiring technique developed and primarily used in the United Kingdom that provides two independent conductors for live, neutral and protective earth (ground) within a building for each connected load or socket. 557px-Ring_circuit.svg.png ring distribution Ring Main Distribution Size of cable used to ring system is 2.5 mm2. Installation Rules of Ring System at basement Rules for ring circuits say that the cable rating must be no less than two thirds of the rating of the protective device. This means that the risk of sustained overloading of the cable can be considered minimal. In practice, however, it is extremely uncommon to encounter a ring with a protective device other than a 30 A fuse, 30 A breaker, or 32 A breaker, and a cable size other than those mentioned above. The IEE Wiring Regulations (BS 7671) permit an unlimited number of socket outlets to be installed on a ring circuit, provided that the floor area served does not exceed 100 m2. In practice, most small and medium houses have one ring circuit per storey, but for this building should having more. An installation designer may determine by experience and calculation whether additional circuits are required for areas of high demand; for example, it is common practice to put kitchens on their own ring circuit or sometimes a ring circuit shared with a utility room to avoid putting a heavy load at one point on the main downstairs ring circuit. A heavy concentration of load close together on a ring circuit can cause minor overloading of one of the cables if near the end of the ring, so kitchens should not be wired at one end of a ring circuit. Unfused spurs from a ring wired in the same cable as the ring are allowed to run one single or double socket (the use of two singles was previously allowed but was banned because of people replacing them with doubles) or one fused connection unit (FCU). Spurs may either start from a socket or be joined to the ring cable with a junction box or other approved method of joining cables. Triple and larger sockets are generally fused and therefore can also be placed on a spur. It is not permitted to have more spurs than sockets on the ring, and it is considered bad practice by most electricians to have spurs in a new installation (some think they are bad practice in all cases).Where loads other than BS 1363 sockets are connected to a ring circuit or it is desired to place more than one socket for low power equipment on a spur, a BS 1363 fused connection unit (FCU) is used. In the case of fixed appliances this will be a switched fused connection unit (SFCU) to provide a point of isolation for the appliance, but in other cases such as feeding multiple lighting points (putting lighting on a ring through is generally considered bad practice in new installation but is often done when adding lights to an existing property) or multiple sockets, an unswitched one is often preferable. Shopping Complex Based on commercial building a project was planned by the New Town Development Sdn Bhd. A 40 storey high building will put the shopping complex of seven stories are starting at level 5th to 11th. Thus, the electrical installation for this we propose to use a radial system. We feel the radial system is suitable for shopping complex. Because there are a lot of use of electrical appliances such as lights, air conditioners and so on. In addition, the radial system is easy to designed, built and maintained. Shopping Complex at level 5th Shopping Complex at level 5th 8th Offices In this building project, a total of 29 levels will be provided for offices start from level 12th to 40th. Based on this, we agreed to use the same method of electrical installations such as shopping complexes, namely the radial system. This method is ideal because it is easy to maintain. In addition, if there is damage to the wire. It is easily known and easily repaired than the ring system. Office Radial System in Shopping Complex and Offices The radial system is widely used, economical systems often found in low-load density areas. To reduce the duration of interruption, overhead feeders can be protected by automatic reclosing devices located at the substation or at various locations on the feeder. This device reenergizes the feeder if the fault is temporary. To further reduce the duration and extent of customer interruptions, sectionalizing fuses are installed on branches of radial feeders allowing unaffected portions of a feeder to remain in service. Radial distribution systems are the simplest systems to plan, construct, and maintain, but are also the least reliable because of the radial nature of the design being served from a single source at a time. If any part of the system experiences a failure, some or all of the customers served by the radial feeder will be without power until a repair is completed. Straightforward design, lower cost, and decent reliability are the distinguishing characteristics of the RDS. An auto-loop distribution system is a special type of radial distribution system and is differentiated by having two feeders that tie to a customer load. The auto-loop system automatically senses the loss of one source of voltage and quickly and automatically switches the load to the second feeder. This type of system adds reliability benefits by keeping outages to a few seconds (or less) but the added cost of having two sets of utility equipment at one location, could be as high as hundreds of thousands of dollars for each installation. radial distribution Radial System Radial system distribution Size of cable commonly used for circuit radius is 4 mm2 Rising Main Distribution for commercial building For multi-storey buildings such as this are ideal to use the rising system. This is because, to ensure that each level of the building is fully supplied with electricity from renewable sources of electricity. A riser is a feeding cable or pipe giving supply to upper floors of a multi-storey building (high rise building). The above picture shows a typical installation of bus duct rising mains in the riser room at individual floor of a high rise building (The Bus duct was taken in the riser room at one of the upper floors of a high rise building). Most of the major components of a bus duct riser system. In electrical works, a riser is a set of cables the supply the upper floors. The feeding cables rise up straight to the top floor. Then at each floor a tap-off unit is connected so electricity can be supplied to that floor (for this project, we propose the radial distribution system). An alternative is to run one individual set of cables to each floor. Then there would be many cables that need to be installed the number of which is directly proportional to the number of upper floors. There are actually three risers, first one is the normal main electricity supply. This supply is just the normal authority supply like the one you have in your house. The 100A tap off unit is for this riser. The second tap off, which is one of the 60A units, is what is called essential supply, or emergency supply. It is a normal authority supply like the one you have from the 100A tap off unit above. However, it is also backed by a standby diesel generator. This means that if the electricity supply from the authority distribution network fails due to problem with their underground distribution cables or whatever, the standby electric generator would kick in and switch in the locally generated electricity to this electrical riser. Large capacity electric generators are expensive. Therefore, it is not economical to supply all electricity needs in the building from this generator. That is why separate electrical risers are used, and the normal riser is not backed by the generator supply. The third tap off unit (the second 60A unit) is for the air conditioning system. It is quite common (and is considered a better design) to have a separate feeder cable for the air conditioning and mechanical ventilation (ACMV) system in a large building. That is the reason for the third electrical riser here. rising main detail Rising Main Distribution Rising main distribution is use to distribute 415v 3-phase electricity from main distribution board to all floors. The copper vertical bus bars which run up in electricity cable riser. The vertical duct or trunking to the height of the building. To prevent the spread of fire and smoke, fire barriers are incorporated with the bus bar chamber at each compartment floor level. One more point to note here is that some office buildings use the generator-backed supply example like essential supply to feed the electrical riser for the air-conditioning system. With this arrangement, ACMV equipment that need to continue operating even during the mains failure do not need to be connected to ESSENTIAL supply riser, which is why it is given a separate riser in the first place. Observe the large flexible conduits coming out from the bottom of the tap off units and connect to the orange-colored electrical trunking. Some installations use rigid metal trunking for this purpose. Cables are run from a tap off unit into the flexible conduit to go to the orange metal trunking. They run inside the trunking to connect to the respective sub-switchboard. The switchboard for the air conditioning system is normally located inside the AHU room of that particular floor. From the sub-switchboards, separate outgoing cables are run inside the trunking to connect to separate distribution boards (DB) on that particular floor. Even though electrical installations at hospitals are relatively much more complex than the office building above, the installation at their hostel and staff quarters buildings are usually very simple. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjripe6ufY0gigmVsNjD9SQs7MJp7iLacIO0uhxlmWgYm1bKdxEnew7OcUlb1XfgP0_aQxB99oeTInbAS2oebUxamN9-w6Gm3xAik1WF6g-z7XgNQ1mV1AkQLsJGwee7uWr22znnXoiJiM7/s320/Floor+Sub-switchboard+Picture.JPG Typical bus duct rising main at individual building floors https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhEm4RiMp_kCyx7MKzY7k6JJ2oi4vPlCtyLoP-Itq4Wq4c0ldyyNX6HEGaitzpQZAdUGd1PpG5eQaw_0K2QMZ3iuS2-nZnMMBD6Y4iheY5aPxXFv3hdVbJ57Cf_wE3fd_DY0nSxDfpT3FDK/s320/Electrical+Busduct+Riser+Picture.jpg The electrical riser room Basically, there only two new components at each riser, which is the Termination Box (Feed In Box) and the incoming cables that terminate into the termination box. The generator-backed Essential supply cables need to have red colored insulation. It is because this supply is part of the fire emergency system of the building. A fire-rated cable must be able to continue operating for a certain number of hours during fire before it fails. This is the requirement. It used to be MICC (mineral insulated copper cables) cables that play this role, but now people use mostly the fire-rated cables for this purpose except in very special installation condition. The fire-rated cables are cheaper, easy to install and maintain. The black-colored cables are from the Normal supply. That means the other ends of the cables are connected to the Normal Supply main switchboard. While the red cables are connected to the Essential Supply main switchboard. Which means the Essential Supply main switchboard is the one that is backed by the standby electric generator. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhZeC31yP8mQDt4F7iSpiLS-EJC5B5OfX-_8vm1zqTZVJyucb7C_T30rMneTML6C7bsEnK0_Pfqrhby15E8icS5T9NL1gfkjKoeoUgk_saH5BnVmi8l26GoU_L5APGAcSk6huf1w_0_JLTi/s320/Busbar+Trunking+Picture.jpg The bus duct risers at riser room https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhd5M0E1DCYDMNDD58eVabbypxdP8wj-p8C61Mn2t7mYjuvap3CX-wv2QHAATsToEsfkSDglguvNYORPtYpNwZFznp-Sjt9A5LVJpMQCMXkjUJrUQ6ctpgmJkVjUC5iA4th1vS2FjOaLxWE/s320/60+A+TPN+Tap+Off+Unit+Image.jpg The front view of one of the 60A TPN tap off units https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj23aYHWrba2u5OASaWqbYQjYwZ-qxOT1eEk_xpTc5xZNYpR4lsAaDSr7fjtTtgV0CQkYlxKtHFz5qpLqVAp1UQtoBXq5mbwI6yRqCmZGbgZ0ZUTLdfIoftVVbtp-WBylg2fDxsoI8vsXiW/s320/Busduct+Conductors+Arrangement+Image.JPG A closer view of the vertical bus duct showing the arrangement of the conductors inside Cables and busways A busbar trunking system comprises a set of conductors protected by an enclosure. Used for the transmission and distribution of electrical power, busbar trunking systems have all the necessary features for fitting: connectors, straights, angles, fixings, etc. The tap-off points placed at regular intervals make power available at every point in the installation. A busbar trunking is placed at the offices. http://www.electrical-installation.org/w/images/c/c9/FigE37.jpg Busbar trunking system design for distribution of currents from 25 to 4000A. The various types of busbar trunking Busbar trunking systems are present at every level in electrical distribution: from the link between the transformer and the low voltage switch switchboard (MLVS) to the distribution of power sockets and lighting to offices, or power distribution to workshops. http://www.electrical-installation.org/w/images/3/32/FigE38.jpg Radial distribution using busways at the offices There are essentially three categories of busways that we proposed for the commercial building, that is; 1) Transformer to MLVS busbar trunking Installation of the busway may be considered as permanent and will most likely never be modified. There are no tap-off points. Frequently used for short runs, it is almost always used for ratings above 1,600 /2,000 A, i.e. when the use of parallel cables makes installation impossible. Busways are also used between the MLVS and downstream distribution switchboards. The characteristics of main-distribution busways authorize operational currents from1,000 to 5,000 A and short-circuit withstands up to 150 kA. 2) Sub-distribution busbar trunking with low or high tap-off densities Downstream of main-distribution busbar trunking, two types of applications must be supplied: Mid-sized premises (industrial workshops with injection presses and metalwork machines or large supermarkets with heavy loads). The short-circuit and current levels can be fairly high (respectively 20 to 70 kA and 100 to 1,000 A). Small sites (workshops with machine-tools, textile factories with small machines,supermarkets with small loads). The short-circuit and current levels are lower (respectively 10 to 40 kA and 40 to 400 A). Sub-distribution using busbar trunking meets user needs in terms of: Modifications and upgrades given the high number of tap-off points Dependability and continuity of service because tap-off units can be connected under energized conditions in complete safety The sub-distribution concept is also valid for vertical distribution in the form of 100 to 5,000 A risers in tall buildings. 3) Lighting distribution busbar trunking Lighting circuits can be distributed using two types of busbar trunking according to whether the lighting fixtures are suspended from the busbar trunking or not. Busbar trunking designed for the suspension of lighting fixtures These busways supply and support light fixtures (industrial reflectors, discharge lamps, etc.). They are used in supermarkets, department stores and warehouses. The busbar trunkings are very rigid and are designed for one or two 25 A or 40 A circuits. They have tap-off outlets every 0.5 to 1 m. Busbar trunking not designed for the suspension of lighting fixtures Similar to prefabricated cable systems, these busways are used to supply all types of lighting fixtures secured to the building structure. They are used in commercial buildings (offices, shops, restaurants and etc.), especially in false ceilings. The busbar trunking is flexible and designed for one 20 A circuit. It has tap-off outlets every 1.2 m to 3 m. Busbar trunking systems are suited to the requirements of a large number of buildings. Industrial buildings: garages, workshops, farm buildings, logistic centers, etc. Commercial areas: stores, shopping malls, supermarkets, hotels, etc. Tertiary buildings: offices, schools, hospitals, sports rooms, cruise liners, etc. Examples of Canalis busbar trunking systems http://www.electrical-installation.org/w/images/3/39/FigE40.jpg Flexible busbar trunking not capable of supporting light fittings  : Canalis KDP (20 A) http://www.electrical-installation.org/w/images/5/5c/FigE41.jpg Rigid busbar trunking able to support light fittings  : Canalis KBA or KBB (25 and 40 A) http://www.electrical-installation.org/w/images/b/b3/FigE42.jpg Lighting duct  : Canalis KBX (25 A) http://www.electrical-installation.org/w/images/a/a5/FigE43.jpg A busway for medium power distribution: Canalis KN (40 up to 160 A) http://www.electrical-installation.org/w/images/5/52/FigE44.jpg A busway for medium power distribution: Canalis KS (100 up to 1000A) http://www.electrical-installation.org/w/images/4/47/FigE45.jpg A busway for high power distribution: Canalis KT (800 up to 1000 A) Trunking and Conduit System in Commercial Building https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVKZ0EhFztrwVfWNe_DQ-MluHJjQ4W4J1KKzdM0DfyDtf46nRHMml3-8D4hS9rwH0ummYEv-6Gxaz8RPiY67vBu11x5Dh0OMj5nKfXnyDI6R91QwNoMKnx0ySzjLyV6EGstc3OdWpN7Jjz/s320/Mechanical+and+Electrical+Coordination+Picture.jpg Conduit and trunking This picture shows how the electrical conduit and trunking installation should be coordinated with water pipes on the building. Trade subcontractors (water piping sub-contractors, electrical sub-contractors, telephone cabling contractor, computer network contractor and others) must not be allowed to proceed with the installation of their individual services and equipment on the first come, first served basis. Prior to the commencement of the installation works by trade sub-contractors, a set of proper coordinated drawings, endorsed by all relevant parties, should be made available to all the sub-contractors involved in a particular area. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi29qZ3FH7l562iRquGRl7AjfsfkXS6WRfg8CVo-E3XsoovyrP8VfZ-m4gA9h3URLOQQHgwTo2OJ-zj1uSVUqI8GVi6cC0jXylcfr936frKXRG9uY4KwbleJx7TksgdIGhA3AY19wscmLiU/s320/Below+Slab+Trunking+Installation+Photo.jpg Electric trunking running below soffit of a concrete floor slab There is no electrical installation work of a significant size can be done properly without the use of an electric trunking. A trunking is a larger size of a conduit. When you need to run a number of electric conduits along each other for a significant distance, then consider using a trunking in place of the conduits. There are so many sizes you can choose from. The above picture is an example of a trunking installation above ceiling level, under the soffit of the concrete floor slab. we also labeled some of the other services there for the benefit of those non-electrical readers who need pictures like this for reference, to know what is what among the myriads of pipes, conduits and trunking running above the ceiling level. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgH4hnYdNeJZB5AhSRjMt9AUHXUUu9RUK4woEXRdcor5wqv_661CVRkPIBp0KLzLJoez2lkKlU7xR8vsIcVpTu_dt5evnOCRiBejw2PNQOCNjr6zjEuZVjGkxOktwBIHOJrzL9c287oug8D/s320/Wiring+Trunking+Picture.jpg Electrical trunking in and out of the electric panels There are electrical trunking connecting the panels at above and below the panels. But the box-up walls have hid them. This picture is metal trunking. In future, the maintenance electrician would need to access and open the cover of the trunking in the repair and upgrading works. Therefore, a means of access is required, which was not provided at all at the mock-up unit. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhthoYNNwKrxqEQWgOZnQlTS-vTpUuRocYY3dk7ehW2dNUPinS6xaBQS639u79Jnu57nyV-MKfCJWpbuaQaizMDWama3sxaP2PrKzvdvdnW0L6ArNgffYwT5Lnf7JZJ_XroUoK3fTJUfLhM/s320/Underfloor+Trunking+Installation+Photo.jpg Under floor trunking installation The under floor trunking system has been around for a long time. An under floor trunking system is an alternative way of providing the dedicated routes to run electrical cables, telephone cables or any other wiring cables. An 11KV cable is not a wiring cable. A 25 sq.mm electrical feeder cable to supply an 11 KW fire pump panel is not a wiring cable. The 1.5 sq.mm cables that are used for wiring the office lights are categorized wiring cables. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-lL3ysX5r00bPNJSNcADyWi6wfkSfmhgJYtgsbyZWrdkR-KmWQUVWCI2TsOJ0aFzBlW46Y5BI9Dtim3Q2BuwubwM6f51wNp6RkoLRDLFM6lZp6iStyZqAWejysi9boeniChXC1iQYv4N7/s320/Surface+Conduit+Installation+Picture.jpg Surface conduits The conduits are used to protect the wiring cables that carry the electrical current. Electricity is dangerous. Even though the electric conductors that carry the current is insulated by some PVC covering materials or whatever, the covering material is not strong enough to protect the cable from damage. When the covering is damaged, the electrical conductor inside may be exposed to touch or it can also unintentionally come into contact with things that can carry electric current. This scenario would present a high risk of electric shocks. Therefore, we protect the electric cables so that they do not present the dangers of electric shocks to people (or animals). A second reason to protect the cables is to make sure the electrical system stays reliable. When the cable PVC covering is damaged, the conducting metal can come into contact with other metals that are in contact with earth. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXvquIbsllwTPrqvZ-5d-a-bjt-_d0PIvLxOo1IOOrXCnIO0MZwcCIB_v-i3emgSjKh5_pC1Nv1J6BsvspveRT1LPa84nhrO3cKQLrEZDzGuqHgOBNMtQdiUTobbu8es7KwaG1Cfrq71L7/s320/Overhead+Projector+Installation+Picture.jpg A motorized overhead projector The electrical contractor produced a mock-up unit of the installation bracket for motorized overhead projector.

Increasing Student Achievement through Preventing School Violence Essay

Increasing Student Achievement through Preventing School Violence Introduction School violence is any type of violence, whether it is a simple threat on another student or a school shooting, that happens in the school environment. Student achievement is the efforts made by the student to work hard in the classroom. The purpose of this research paper is to examine how school violence impacts student achievement. It would seem that school violence would have a negative impact on student achievement. If this is the case then we need to do what we can to prevent violence in schools. Technology can be used to help control school violence. Information on School Violence Violence in our schools has become an increasing problem. Within the United States alone, there have been approximately twenty-two school shootings since 1978 (Cruz, 2002, p. 53-54). Eighteen of the twenty-two occurred during the 1990’s. It has been approximated that â€Å"a school crime occurs every six seconds† (Day, 1996, p. 9). We must ask ourselves why school violence has flourished. When we try to answer this question, we tend to blame society. Violence in the media seems to be the number one cause for violence in the school. However, society and media are not the only things to blame. There are so many reasons for why school violence has become increasingly more popular, but there is one thing that can be said for sure is that our students need to be able to learn and work in a safe environment. The need to create â€Å"a school environment that is free of violence and drugs has become a public priority† (Flannery, 2000). People need to pull together as a community and help in the fight against school violence. We need to give students... ...zine/vault/A2857.cfm 24.

P&G Advertising Strategy Essay

For marketing students at IIM Ahmedabad, 9th of January, 2011, is anything but a typical Sunday. They have resisted the temptation to join their batchmates in a lazy basketball game and appear oblivious to the cheerful riotous frenzy of the kite festival on the banks of the Sabarmati. Instead they have been pitted against each other all morning in a brand exercise organised and masterminded by P&G. The prize? A dinner date for the teams with a man responsible for running the marketing function of one of the most powerful FMCG companies on the planet, Marc Pritchard , global marketing and brand building officer, P&G. However, even students who do not make the cut get a chance to experience Pritchard firsthand when he addresses a respectably packed hall that evening. Soon after he’s done, the questions fly thick and fast. These include some potentially embarrassing posers. How does P&G feel, one student wants to know, about its campaigns being ambushed by its archrival HUL? Few people have forgotten the teaser campaign about a mystery shampoo last year (that was revealed to be P&G’s Pantene) being hijacked by Dove from the HUL stable. Pritchard opts to take the high road on this one: â€Å"We can’t prevent any competitor from ambush (surprise attack). But if you focus on the consumer, what your brand is doing to serve the consumer and if you have a big idea, you will win most of the time. † And that’s a running theme through pretty much everything that Pritchard has to say. Whether he’s addressing students at IIM-A, the media or an audience at the Cannes Lions Festival, he’s a tireless champion of brands serving consumers or â€Å"purpose driven branding. † P&G spent most of the 1990s establishing a global footprint. Now, according to Pritchard, it finally has the chance to live up to its purpose. The first step was getting senior management to define a purpose for each of the brands in the P&G stable: a blueprint on how the company could touch and improve lives. Pritchard explains, â€Å"We still have a core benefit but are thinking more broadly on how we can deliver it. We are very focussed on sharpening what the brands stand for, identifying human insights that can translate into big ideas. † Bold Gamble However those prepared for a lofty chronicle of CSR and corporate do-gooding are likely to step back, a little disappointed. Pritchard’s showreel of purpose driven work from P&G includes pretty much every big campaign the FMCG has come up with recently. This includes the highly awarded work on Old Spice with its cocky ‘The man your man could smell like’ tagline. Pritchard says, â€Å"Purpose is much more than a cause or a corporate responsibility. We deliberately focused on making people define purpose as how brands improve everyday lives. A cause is just a piece of it as opposed to the whole thing. † This helps take purpose out of an ivory tower. It’s no longer something that resonates only with consumers in developed markets, fed up with hard sell, looking for corporates to do something more. Instead it could even be used as an effective go to market strategy. Which is pretty much the case with Pampers. Pritchard defines the brand’s purpose as â€Å"to improve a baby’s healthy, happy development. Its benefit is dryness and comfort that allows babies to sleep, play and explore more. When they do that, they develop better. By the way, it’s also making their mom’s lives a lot better if they sleep through the night. † To bring this purpose to life, P&G sends pediatricians to villages with tips on how to help the baby sleep and advice on immunization, besides using this interface as a sampling opportunity. The one pack = one vaccine program run in association with the UNICEF is tied into this larger purpose too. â€Å"It helps bring the community of moms together since they like to help other moms,† says Pritchard. Even ‘Women Against Lazy Stubble’ for Gillette, a homegrown campaign, has something larger driving it. Purpose takes on a more meaningful role in developing markets,† he explains. The vans that propagate the program give young men tips on shaving, how to dress, handle an interview and talk to women. Purpose coincides well with P&G making a concerted push into non-city markets not just in India but in other countries like Brazil and China that have a yawning urban-rural divide. P&G is focusing on stores because it’s the first moment of truth for the rural consumer. Pritchard says, â€Å"We market back from there to create awareness to get them to that point. † There are approximately 7 million high frequency shops in India and P&G has covered 4 million of these so far. A fair amount of product and package development is being done to cater to this segment. Using the store as the starting point also helps make the entire process less sporadic. Pritchard states, â€Å"It means you are always on. We have consolidated the number of distributors into a core highly capable, powerful group. We give them the material, knowledge and know how on display. † India is in some ways at the vanguard of P&G’s rural drive. One of the things pioneered in India was generating more household trial. Pritchard admits, â€Å"It was Sumeet Vohra (chief marketing officer – Asia, P&G) who created this machine to identify what it was going to take to get these products in the households, as well as the tools to measure performance. Much of what we learnt in India has been exported to other markets like Africa for example. † The recent acquisition of Paras by Reckitt Benckiser proves that multinational giants look to India for a lot more than its large consumer base. Pritchard gives a diplomatic answer when asked if there are any local heroes that he’s got an eye on. But P&G invariably unearths little jewels with every acquisition, he says. Like Koleston which was not very big globally but strong in Latin America, particularly in Brazil, around the time Wella was acquired. P&G took the brand to Mexico, Europe and are now launching in India. Pritchard goes further back for his next example: Richardson Vicks in 1985 had a very tiny brand called Pantene that accounted for $70 million in sales. He says, â€Å"We put the new technology in, and launched it in Taiwan and came up with Pantene Pro V. Now it is over a $3 billion brand. † To be chosen for the big push, the brand needs equity and it helps to have some sort of a story. Like Max Factor’s SK2 which was made with Pitera, a yeast extract used by monks in Japan which kept their skin in a better condition. â€Å"We built from that story, tested it in different markets and now it’s more than half a billion dollars and growing like crazy,† says Pritchard. In a classical FMCG battle, market observers may be tempted to brand P&G as a pacifist, with hardly any aggressive countermoves towards competition. But, combining brand awareness with social programmes, driving its brands further into the hinterland and acquiring a knack of creating billion dollar brands, Pritchard knows that the company is pushing the right levers.

Atlantic Slave Trade Essays - African Slave Trade, Racism

Atlantic Slave Trade Essays - African Slave Trade, Racism Atlantic Slave Trade Atlantic Slave Trade When most people talk about or think about slavery, they look at how it effected the US. The Atlantic Slave Trade had a huge effect on the US but there are no words or expressions that can describe the effects it had on Africa and its familys. It is estimated that between 1450 and 1900, there were 11,698,000 slaves exported from Africa. (Atlantic Slave trade, pg.170) To understand the effects this had on Africa you must consider the families that lost relatives, the stores that lost business, and even the friends that lost friendships. None of the misfortunes can be brought back or replaced. The many lives that were taken can never be brought back to life. This not only effected the African culture when it happened but also it effects todays societies in Africa. The overall net effect of the Atlantic Slave Trade on Africa could never be estimated unless you are inside one of the relatives of a slave. These slaves died for no other apparent reason than the color of their skin. The effects that the slave trade had on Africa were not all negative. Depending on what point of view your looking from, there were also some positives of the Atlantic Slave Trade. In William Bossmans account, he states that as soon as the king arrives he will be satisfied with an amount of one-hundred pounds in Guinea value. (Atlantic Slave Trade, pg.181) So the kings and most of all the slave traders benefited from the slave trade. One benefit from the Slave Trade would definitely be spiritually. The great misfortunes had to strengthen the inner souls of the people and relatives that were left behind. A lot of these people had nothing left but themselves so they had no choice but to deal with it and get stronger mentally and spiritually. One other benefit from the Slave trade would be that the African Culture was spread to totally different continents. All of these slaves were taken to different places and they went on with their business while all these other people that either ow ned these slaves or watched over them got to see life from the Africans side of the fence. They got to see different rituals and habits that they have never gotten to see before. In my opinion the drawbacks of the Slave Trade greatly outweighed the benefits for the African people. The families of these slaves still feel the drawbacks even today. When these people look back at a family tree, all this does is bring back memories of the torture that their relative or relatives endured. The continent itself took a huge hit on its population. Many of these slaves could have played a big role in Africas future. Many could have gone on to be nation leaders or even business owners. In 1502, the first African slaves were reported in the New World. (Amistad.mysticseaport.com) This was the start of a great mistrocity to many families in Africa. The overall effect could never be estimated because we are not in the bodies of those people who lost loved ones. We can not feel the pain that they feel, therefore we cant say what the net effect is or was.
