7Introduction-
In the modern era, Electricity is considered to be the most important and necessary resource in day to day life. People around the world are directly or indirectly dependent on this form of energy. Although it is very important source of energy but its overuse and misuse led to a critical issue of unavailability of it in many rural areas. The utility of electricity is numerous, in fact it is most common source of energy used in every appliances, equipments and machines in industries, households etc. In other words, we can call it to be the basis of livelihood in this world after air, water and food. The usage of electricity was primarily considered to be in household appliances and industries but after the introduction of electricity in the world of transportation, it became a remarkable breakthrough in the field of science and technology. It gave a vision of saving non renewable sources of energy such as coal and petrol for the transportation purpose and also helped to eliminate the problem of ever increasing release of toxic gases which are produced during the burning of coal and petrol. It is a serious matter of concern for the scientists around the world to reduce the level of carbon dioxide and other toxic gases from the environment which is becoming the major cause of global warming. With the development of latest technologies, entrepreneurs across the globe are trying to invent new technologies for alternative fuel source which is relatively cheaper, renewable, environmental friendly and can have multiple utility. Efforts are being made in the field of transportation industries by developing battery oriented vehicles which will work by using energy provided by batteries. In the past, Railway engines in many countries were running by using diesel as their source of fuel but after the introduction of electrical engines, the usage of diesel was cut down by 50%. Along with electricity, magnetically derived energy is under development in the transportation industries. As the concept of physics says, due to presence of magnetic field, electricity can be generated and vice versa is also possible. In this report we have discussed various sources of alternative sources of energy which has the huge potential in the upcoming future of transportation industries.
Hybrid Power-
Much emphasis is given for designing hybrid vehicles by using advanced technologies and latest machinery as an alternative for petrol or diesel oriented vehicles. PHEVS (Plug in hybrid electrical vehicles) in the present world has become the subject of interest because of their potential in replacing oil operated vehicles, natural securities and environmental benefits. The primary objective of PHEVs is to reduce the cost of fuel by replacing gasoline with electricity. Although the cost of these vehicles are still the matter of concern as these vehicles are very costly due to the usage of high voltage batteries. Although of its long term utility and savings for the consumer, its cost is the biggest hurdle for widespread commercialization. The cost of these vehicles is expected to reduce with time due to rise in demand of these vehicles. With the changing technologies and its advancement, scientists are trying their best to develop long lasting chargeable batteries for running cars which will definitely give the companies a hope of making those cars at cheaper rate. Finally these hybrid vehicles also provides very unique convenience attributes such as less frequent visits to gas stations with emergency power back up, which is generally not available in other conventional vehicles.
Smoke free trains-
Most of the conventional sources of fuels are getting depleted day by day. The increasing toxic gases load in the environment which is one of the primary reasons behind global warming provoking the governing bodies to take some serious steps towards developing a smoke free source of energy and fuel. Although much emphasis has been given to develop vehicles run on batteries but due to its lower speed and higher cost, common people are not attracted towards these vehicles. The government is now shifting back towards the electrical source of energy and fuel as the source of fossil fuels are getting costlier and due to its scarcity. The trains are now running via electrical engines and most generators, motors are also utilizing electrical energy for their working. Due to its long term utility this source of energy can bring a revolution in the transportation industries.
Electricity and Renewable Fuel alternatives-
One of the major areas of concern for scientists, governing bodies and the transport industries is to find out an alternative source of energy which can effectively replace the conventional source of fuel. At present the vehicles primarily uses petrol, diesel and diesel blended with bio-diesels. With increase in air pollution, it has became a very serious task for the scientists and innovators to device latest technologies to overcome such problems and also to find alternative source of fuel which reduces the emission of toxic gases and prevent air pollutions. Introduction of bio-diesel has opened many channels to develop blends with good flash point with conventional diesel which will emit comparatively less toxic gases. Bio diesels are made by many ways including degradation of cellulose, using waste cooking oil, using plant extracts etc. Many other sources of energy are being produced using plant extracts such as electricity for charging batteries, fuel cells etc. Electricity from water are produced since many years also known as hydro electric energy which is now the major source of electricity production after thermal power stations. Hydrogen fuel cells are also used as a potential source of energy which doesn’t releases harmful and toxic gases on its usage. Moreover by using biological wastes many organizations and companies are now focusing on production of biogases as the source of fuel by using micro organism as the potent converter of biological waste into various useful gases like methane. All these sources of energy directly or indirectly will help the transport companies in the coming 10-20 years, though much research and development is required to increase the efficiency and reproducibility of these sources of fuels.
Magnetism as source of power-
Usage of magnetism as a source of running the vehicles has bought a revolution in the transportation industries. The utility of these magnets in the form of magnetic levitation encourages the source of clean energy. Magnetic levitation is very advanced technology. There are various application of magnetic levitation like magnetic levitated trains, elevators, airplanes etc with one thing in common, it lack contacts resulting in no friction wear and tear. Therefore it increases the efficiency, maintenance cost and longevity of the machines. There are many countries attracted towards this technology and the application of this magnetic levitation in transportation like train got an important breakthrough in term of speed up to 300 miles/hour with very safe and efficient machinery. Magnetic levitation can be considered as the conventionally solution for the future in the world. The country like Japan has used this technology and was able to achieve the speed of 361 miles per hour by replacing electromagnetic coils with superconducting magnetic coils. These superconducting coils are also used for the elevators which are controlled through magnets. One of the advancement in technology in California called Inductrack which was specially designed and controlled by magnets that offers higher repulsion force and able to achieve higher speed. One of the major applications of Magnetic levitation was supporting airplane in the wind tunnel. In simple words, this technology supports an object in the air without any physical contact but only by magnetic force. The field was used to counteract the gravitational force on the object and any other acceleration. Therefore this application of electromagnetism has opened the gateway for many such possibilities of designing efficient and less fuel requiring vehicles.
Conclusion-
In this present world of competition and technology, electricity is the major source of livelihood in this fast moving world. In our day to day life, we can’t even imagine of doing any work without the absence of electricity. Electricity has also played a major role in the field of transportation and given us the opportunity to fight against the cause of global warming by eliminating the chances of release of toxic gases which are generally released after the burning of some conventional fuels. Electrical hybrid vehicles became one of the remarkable breakthroughs in the field of science and technology, as it is operated on batteries which doesn’t emit any toxic gases and also help in saving conventional non renewable sources of energy. Much emphasis has been given to improve the shelf life of batteries so that the overall cost of these vehicles can be minimized and a common people can afford it for his/her livelihood. Along with that discovery of bio- diesel, hydrogen fuel cell has given a pinhole vision for developing new sources of fuels for the future usage. Magnetic levitation technology, which is also considered as the solution of future problem of this world has made possible for designing highly efficient, cost effective solution for designing high speed train and airplanes. Thus, the sources of alternative fuel are helping humankind by saving the non renewable sources of fuel with limited emission of harmful gases.

...April 2009 QUESTION 3 Identify the stages in the product life-cycle. Discuss the strategies that marketers could utilize as the product goes through each stage of the product life cycle. First is introduction stage, this stage of the cycle could be the most expensive for a company launching a new product. The size of the market for the product is small, which means sales are low, although they will be increasing. On the other hand, the cost of things like research and development, consumer testing, and the marketing needed to launch the product can be very high, especially if it’s a competitive sector. Example is 3D TVs which need to compete with the LCD’s TV in pricing and cost. The growth stage is typically characterized by a strong growth in sales and profits, and because the company can start to benefit from economies of scale in production, the profit margins, as well as the overall amount of profit, will increase. This makes it possible for businesses to invest more money in the promotional activity to maximize the potential of this growth stage. Example is Smartphone. Nowadays, people getting interest to buy smartphones as they can fully utilize the phone to help them in daily activities. During the maturity stage, the product is established and the aim for the manufacturer is now to maintain the market share they have built up. This is probably the most competitive time for most products and businesses need to invest wisely in any marketing they undertake. They......

...Keynes’s theory about market equilibrium   To explain briefly the main thing that John Maynard Keynes achieved as an economic theorist in his famous General Theory of Employment, Interest and Money  (1936), let us consider first the tr aditional concept of market “equilibrium,” starting with theeveryday notion of the difference between a “buyer’s market” and a “seller’s market.” Bargains – the chance to buy things for lessthan you think they are worth  – make for buyer’s market . An abundance of eager buyers (especially if they are affluent) makes for a seller’s market. “Equilibrium” would occur when there is neither a buyer’ s nor a seller ’ s market, i.e. when ( a ) the price(s) that sellerswould be perfectly happy to get and ( b ) the price(s) which buyers are happy to pay are the same, and so no haggling is needed. Youmight imagine that each day in the stock market (back in the old days when it was realistic to consider the stock market as a merelynational thing that closed down overnight), a temporary general equilibrium would be reflected in the prices posted at the end of the day. (And indeed the concept of general equilibrium in the market was invented, in the 1870s, by an economist alert to thatphenomenon.) But if you imagine that during the night some potential sellers and/or buyers must be eagerly awaiting the nextmorn ing because they think the closing prices show how they can profit by further dealing and wheeling, you can see that......

Abcde Assessment Case Study

...Case study This paper will use a case study approach to explore the registered adult nurse’s role in the holistic care, in the first 24 hours, given to patient presenting with chest pain, caused by a myocardial infarction (MI). Using clinical guidance and evidence based research. The case study will use the ABCDE assessment framework. The resuscitation council (2006) recommends that nurses should follow the ABCDE method when assessing acutely and critically ill patients as it ensures nurses quickly and accurately identify acute illness and promptly begin management of the condition/ illness (Jevon, 2010). The aim of the assessment is to determine the cause of the chest pain efficiently and prioritise care needed. The main priorities were; pain control, informing appropriate medical staff and the nurse in charge, reperfusion of myocardial tissue, managing anxiety and monitoring for complications of MI and the effects of the treatment given. A MI occurs when a coronary artery becomes occluded, most commonly by a thrombus due to the rupture of an atherosclerotic artery which results in the necrosis of myocardial tissue because of the ischemia the thrombus causes (O’Neil, 1996). For the purpose of this case study and in order to protect confidentiality and anonymity the patient used will be fictitious and given a pseudonym. However the events the case study follows are very much a reality (Edwards, 2002). Case scenario Brian, a 64 year old male, was recovering...

The phases listed in order from left to right are: interphase, prophase, prometaphase, metaphase, anaphase, and telophase. During interphase the DNA is replicated and ready for entering of mitosis. During prophase the spindle fibers and centrioles start to move to opposite sides of the cell (2009). This is the longest phase. It is also in this stage that you can begin to see that there are two chromosomes attached together (double helix). In Prometaphase the chromosomes are attached to the spindle fibers and begin to move toward the metaphase plate region (2009). When the chromosomes are lined up it is called metaphase. During anaphase the chromosomes begin to separate into the sister chromatids and start to move toward the opposite poles.

Normalization

...1.Introduction Relational database design theory is mainly based on a class of constraints called Functional Dependencies (FDs).FDs are a generalization of keys. This theory defines when a relation is in normal form (e.g., in Third Normal Form or 3NF) for a given set of FDs. It is usually a sign of bad DB design if a schema contains relations that violate the normal form requirements. If a normal form is violated, data is stored redundantly, and information about different concepts is intermixed. To reduce the redundancy in a given relation we need to decompose it in two or more sub relations . Decomposition into highest normal forms required maintaining properties like loss less join decomposition and dependency preserving decomposition. To normalize a relation R we have to remove certain dependencies that exist in it like partial dependency& transitive dependency. Basic definitions 1.1 Functional dependency: In a given table, an attribute Y is said to have a functional dependency on a set of attributes X (written X → Y) if and only if each X value is associated with precisely one Y value. For example, in an "Employee" table that includes the attributes "Employee ID" and "Employee Date of Birth", the functional dependency {Employee ID} → {Employee Date of Birth} would hold. It follows from the previous two sentences that each {Employee ID} is associated with precisely one {Employee Date of Birth}. 1.2 Trivial functional dependency A trivial functional......

The planning and implementing of the care required and evalutaing constantly to ensure that the care provided is working and how I communicated with the relevent medical staff using the ISBAR tool of communication. The timeframe is over a 36 hour period from onset of symptoms to transfer. I will begin by giving a definition of Sepsis, discuss the ABCDE method of assessment and a brief background as to why the patient is in hospital as well as a brief past medical history. Sepsis, a potentially life-threatening complication of a localised infection, can rapidly lead to acute deterioration risking multi-organ failure and death. (Dellinger et al 2008) Sepsis is quite common and it is therefor imperative that every nurse on every ward be aware of the signs and symptoms of Sepsis and the appropriate measures to take to manage it should their patient become Spetic. Having an effective and proven assessment tool such as the ABCDE approach can help assess, treat and therefore improve the outcome for the patient who has become acutely ill (Troels et al 2012) The patient is a 69 year old female admitted to Rehab ward for management of chronic ulcers stemming from severe lower leg Oedma. This lady is morbidly obese and self caring had become an issue prior to admission. She has a number of health issues, she is Afib, has Hypertension, Non Insulin-dependent Diabetes......
