Cosmetic Industry background Analysis in China Marcket Assignment

Cosmetic Industry background Analysis in China Marcket - Assignment Example Due to this, many cosmetics manufacturers have introduced more products in the expanding cosmetic market such as flavored glosses and lipstick, cosmetic packaged in sparkly and glittery packaging, and advertising and marketing using young beautiful models. However, cosmetics market in China is doing well in the manufacturing and packaging of beauty products. For instance, the raw materials of making shampoos are best provided in China by various manufacturers such as: Wuxi Nuoya Machinery Co., Ltd., Yangzhou Chenhua Science &Technology Group Co., Ltd., Shanghai Xiaoxiang Chemical Co., Ltd., and Shandong Freda Biotechnology Co., Ltd., among others (Yang, 2004, p. 123). Cosmetic industry is dominated by a number of multinational corporations. However, sale and distribution is spread over a wide range of businesses in China. Historically, the people of China initially stained their fingernails using gelatin, gum Arabic, egg, and beeswax. The used color represented a particular social cl ass (Tao, 2005, p. 231). For instance, the royals wore silver and gold, and red or black. The lower social classes were forbidden from wearing bright colors. Cosmetics market in China and the world today make a lot of money due to the furious rate of growth of the anti aging industry and the factor of celebrity in marketing and advertising (Tang, 2008). Today in the whole world, beauty is characterized with the youths and many are obsessed with their falling jowls and wrinkles and lines appearing. This is even turning people to undertake cosmetic surgery. This is what has taken my interest in writing this research paper, which will focus on the cosmetic market in China including: wholesalers, manufacturers and retailers; Chinese cosmetic suppliers including raw materials and packaging suppliers (Sunfaith China Ltd., 2005, p. 200). Cosmetic market in China Cosmetic market and industry in China has evolved to a fully fledged market with the emergence of flouring brands (Tang, 2000, p. 311). Within the cosmetic market in China, among the 300 brands, 20 of the brands have a joint venture and leading position of 80% of the share of the market. The cosmetic manufacturers in China are generally located in the inland cities and the Eastern Coastal line (Shen, Liu & Huang, 2005, p. 19). The market produces 90% with sales rated above 60% within the country. With respect to the types of cosmetics in Chinese markets, products of skin care is first in the list with 35% share, products of hair care sharing 28%, and products of make up taking up 29% share, and others are perfumes. According to the cosmetic insiders, the total sales of the cosmetics will probably reach to RMB 80 billion and amount to 12.9% per annum. The wholesalers, manufacturers and retailers are making huge profits in the cosmetic market in China due to the mentioned estimates of sales (Schutte & Ciarlante, 1998, p. 78). China has also emerged the eighth best cosmetic market in the world and second best in Asia. The stiff competition in the cosmetic sector has pushed the industry of cosmetics to combine the cosmetic market, industrialization and internationalization (Pitman, 2005, p. 12). Back in 2005, the scale of market even reached RMB 46 billion, with the cosmetic retail sector reaching RMB 33.05 billion which was much above the expected limit of growth 19.1% (Li, 2005, p. 32). the cosmetic market in China is currently exhibiting the following characters: the cosmetic mark

Was the modernist architect becoming too authoritarian and dogmatic Research Paper

Was the modernist architect becoming too authoritarian and dogmatic - Research Paper Example It is evidently clear from the discussion that architects in the 20th century chose to enhance authoritarian social relations, sought to enhance social control in general and their proportion of social change in specific, and embraced many dogmas to enhance their professional importance. While architecture must use advanced mathematics to construct a building, and certainly architecture is artistic insofar as it is representative of a society's preferences for spaces and is a statement of intent or design on the part of a person, architecture itself must be defined socially in a particular fashion. â€Å"[W]hat characterizes architecture today is its capacity to be studied as a system of significations that establishes different levels and layers of meanings and sense and constitutes one of the symbolic spheres instituted by society†. Hays argues that since 1968, architecture is a â€Å"technical-ideological practice†. As a consequence of this, Hays concludes that it is absurd to call any individual architect or even architecture as a whole â€Å"hermetic† or â€Å"elitist† or authoritarian because it is like calling rain wet: Architecture as an institution is a collective arranging of power as a technical-ideological collective. But architecture, unlike other areas where there is a monopoly of technical power being exerted, must be brought under special criticism because its designs move into the public realm. These are two immensely different concepts. To use a political analogy: Clearly, decisions must be made, but when those decisions are made by one person, it becomes authoritarian. The model of the architect as artist is thus structurally and intrinsically authoritarian, because the idea is that the architect's vision as to how to implement stakeholder needs is implemented and other people in the chain such as customers and workers are irrelevant. Each worker, each customer, each visitor, each policy-maker brings their own touc h to the art that is the final building, sometimes a vital one. The architect tries to form order out of chaos, a chaos that it assumes into existence but has no independent reality, just like all other authoritarians, and does so by trying to make it so that others in the process merely carry out orders and directives or by managing their perturbations and deviations from his ideal vision. Doesn't this mean all art is authoritarian? There is a truth to that, but the authoritarian nature of the self is also called â€Å"autonomy†. When a painter is authoritarian about their process, they are committing no great wrong. They are the only person directly involved, and a customer is free to accept or reject their painting. But architects are far from this. An architect will build public spaces that must be used by people who had no direct veto power or influence into the style being built. This becomes especially true when one considers the idea of artistic spaces being imposed u pon people because they are artistic, to enrich the philistine. This attitude is fundamentally elitist: If most people don't care about artistic spaces, then imposing that onto them is anti-democratic.

Different Types Of Computer Memory

Different Types Of Computer Memory In earlier computers, the most common form of random-access storage for computer main memory employed an array of doughnut-shaped ferromagnetic loops referred to as cores. Hence, main memory was often referred to as core, a term that persists to this day. The advent of, and advantages of, microelectronics has long since vanquished the magnetic core memory. Today, the use of semiconductor chips for main memory is almost universal. In computing, memory refers to the state information of a computing system, as it is kept active in some physical structure. The term memory is used for the information in physical systems which are fast such as RAM, as a distinction from physical systems which are slow to access such as data storage. By design, the term memory refers to temporary state devices, whereas the term storage is reserved for permanent data. Advances in storage technology have blurred the distinction a bit -memory kept on what is conventionally a storage system is called virtual memory. Computer memory can divide into two types: volatile and non-volatile. Volatile memory is a kind of memory that power supply is needed to maintain the stored information. Semantic Random Access Memory (SRAM) and Dynamic Random Access Memory (DRAM) are currently common known semiconductor volatile memory technology. Non-volatile memory is computer memory that can retain the stored information even the power is switched off. Examples of non-volatile memory technology are Read Only Memory (ROM), flash memory, most types of magnetic computer storage devices such as hard disks, floppy disks and magnetic tape. Main Memory Random Access Memory (RAM) is a form of computer stored. It is responsible for stacking away data on a temporarily basis, so that it can be promptly accessed by the processor. Usually, information that stored in RAM is loaded from computers hard disk, included data related to the operating system and certain applications. The weakness of RAM is when the system switched off; RAM will lose all stored information. However, the data still remain stored and can be retained only when the system is running. Computer system is more likely to operate at a slow speed if the RAM is getting full but the data can be retrieved in any random order by computer to back to normal speed. The common examples of RAM are Static RAM (SRAM) and Dynamic RAM (DRAM). SRAM is a type of semiconductor memory where the word static indicates that, unlike DRAM, it does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence, but it still volatile in the conventional lost when the memory is not powered. A SRAM cell has three different states it can be in: standby where the circuit is idle, reading when the data has been requested and writing when updating when contents. Asynchronous SRAM is type of SRAM that available from 4Kb to 32Mb. The fast access time of SRAM make asynchronous SRAM appropriate as main memory or small cache-less embedded processors used in everything from industrial electronics and measurement systems to hard disks and networking equipment, among many other applications. SDRAM memory data access is synchronized with an external clock signal. SDRAM memory bus accepts speeds up to 100 MHz, wh ich says much for their stability and has reached speeds of 10 ns. It comes in 168-pin DIMM (64 bits). Being a 64-bit memory implies that no modules to install modules in pairs of equal size, speed and brand. DDR SDRAM (Double Data Rate SDRAM or SDRAM-II). Operates at speeds of 83, 100 and 125MHz, and can double these speeds data transfer to memory. DRAM is a type of RAM that stores each bit of data in a separate capacitor within on integrated circuit. The capacitor can be either charged or discharged; these two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Due to this refresh requirement, its a dynamic memory as opposed to SRAM and other static memory. The advantage of DRAM is its structural simplicity. It means, there are only one transistor and a capacitor are required per bit compare to six transistor in SRAM and it allows DRAM to reach a very high densities. Second storage devices Computer hard disk is these devices are imported data storage components that are installed in the CPU. Their memory ranges widely, and a user may choose the memory depending on the data needed to be stored and accessed. Memory capacity of computer hard disk are normally used is 120GB to 500GB. Computer hard disk is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read from and written to the platter by read or write heads that float on a film of air above the platters. With the rapidly growth of science and technology, we are having external hard disk that more portable than the computer hard disk. The popular capacity of external hard disk is between 320GB to 500 GB. Removable make this hard disk quickly spread to users and they prefer it then other. In addition, flash memory also the second storage devices that know by users in computer industry. Flash memory is a kind of non-volatile memory which is intended to contribute to portable storage and a convenient transfer of data from 1 computer to another. The data in flash memory can erase and re-programmed as per the users requirements. It only has a specific number of erase and writes cycle that it can with stand, after which it creates a tendency to lose out on the stored. Memory card and USB flash devices are some modes of flash memory. Memory card is commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players and video game consoles. They are small, re-recordable, and they can retain data without power supply. The storage capacity of memory card can up to 4MB. The examples of memory card that we most familiar are: SM / SMC, Memory Stick, Memory Stick Duo, Memory PRO Duo, and Memory Stick Micro M2. A USB flash drive consists of a flash memory data storage device integrated with a USB (Universal Serial Bus) interface. USB flash drives are typically removable and rewriteable and physically much smaller than a floppy disk. For USB flash memory, we know that it bring us a better life, without printing out the document into hard copy but still we can share to each other within it. The Kingston is the most popular brand for USB flash memory. It is portable, small and brings along to anywhere. The capacity of memory in 2010 can be as large as 256GB with the steady improvement in size and price per capabilities expected. Nothing moves mechanically in a flash drive; the term drive persists because computers read and write flash-drive data using the same system commands as for a mechanical disk drive, with the storage appearing to the computer operating system and user interface as just another drive. Flash drives are very robust mechanically.A flash drive consists of a small printed cir cuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case which can be carried in a pocket or on a key chain, for example. The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. Most flash drives use a standard type-A USB connection allowing plugging into a port on a personal computer, but drives for other interfaces also exist. Computer memory closely related to computer and our daily life. To store data and information, we need it. In the future, the computer memory will be more portable and with all non-volatile memory to give us a better working environment.

Leadership and Management Essay -- essays research papers

1. A. Is there a difference between effective leadership and effective management? Yes, I believe that managers are analytical, structured, controlled, deliberate, and orderly. Leaders are experimental, willing to take chances, visionaries, flexible, unfettered, and creative. These are the differences between management and leaders. B. Someone from the 21st century who I believe is an effective leader is Steven Jobs, of Apple computers. I believe he is an effective leader because he pursues visions even when his competition has a strong hold on the computer industry. He still motivates his people to keep coming up with ideals to stay competitive with Microsoft and not let them run a monopoly on software and patents on computers. His power base is that he senses opportunities and pursues dreams to keep his company competitive. C. A leader of the opposite sex that I think is like Steve Jobs is Martha Stewart. She had a vision to take home decorating and cooking to another level by connecting with millions of homemakers through TV shows and the selling of her products through K-mart. Martha was just pursuing her dreams to play in the corporate world with men. She senses opportunity when she sees it. She had the intuition to make her company a profitable one when her critics told her it would never work. D. I do feel that there is a general pattern of male/female leadership styles because leaders must be able to apply influence, develop people, set examples, inspire people, mana...

Partnership transportation Essay

Partnership transportation in broad mind means involvement of all parties in the running and operations of transportation and its impact, retrieved from a journal on â€Å"facilitating partnership in transportation (2005) page 7 and 8†, by James A Merchant and Barbara T Harder. Transportation and maintenance is a work done by local government and the state in collaboration with other partners. Partnership transportation involves integration of various bodies in the transport sector. Partnership in transportation sector can be classified into two categories. First there is incorporation of all means of transport, this include pipeline transportation method, railway transportation method, airway, shipment, road transportation methods. Second, there is integration of private companies and people that own the vehicles, marine ships, airbuses and pipelines, chamber of commerce and industry that has the potential human resource powers to innovate new technologies that enhance fuel saving, and other automobile associations. In transportation, no specific body that can handle transportation sector individually without cooperation of other parties as indicated by Mark Wymond-1917-178 pages in his book â€Å"Our transportation problem† ,www.worldcatlibraries.org . For example, poor management of institutional framework may deteriorate roads management, railway management etc. Poor conditions of road, railways and airports because of poor services and maintenance may be another issue of concern. Lack of defined responsibilities of each associate party, ineffective and weak management structures can also have adverse effects in the transportation sector. Lack of managerial accountability is another issue of concern; this is because transportation itself is an individual identity. Hence, there must be somebody to respond to various issues that may arise. The responsive party would include government officials and private transport cartels.   Failure due to road and railway engineers adversely affects transportation sector. The government is involved in financing public roads and other means of transportation. The government makes sure that there is rule of law that is followed. It is the work of govern to mitigate the transportation processes.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Historical background Partnership transportation resulted in manner that was not supposed to be. It dates us back to the early seventeen century when the prisoners in Victoria were being transported from various parts of the country to Australia.[1] This was an intention to punish the prisoners since there were no enough prisons to keep them. Therefore, a solution was found on to how to punish those prisoners. One of the best ways to do that was to compel the prisoners to carry out hard work, tiring jobs and boring tasks such as walking miles away to transport goods or to peak oakum.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Farming is another issue that resulted to partnership transportation. This included commercial activities occurring as transportation route; this made the construction of various transportation route e.g.   The Chin ago canals, and rail lines were developed, linking the town to other parts of the region. A tract was opened to settlers and land companies by the Clinton treaty in 1788. The growth of Hamilton town was because of stimulation by several main roads, which crossed from east to west. Therefore, there erupted a relationship between the farmers and transportation board in various countries. Transportation of farm produce resulted to growth and development of transportation sector. On the other hand, farmers benefited from easy means of accessing the markets for their produce. In the process, trading started and business thrived tremendously. This resulted to stiff competition that enabled business partners to merge and to come up with an idea to work together, this is how the partnership transportation emerged. That resulted to automobile firms that started competing on manufacturing different kinds of vehicles. Since then the technology has advanced to the manufacturing of space ships. Status: current issues, practices, developments, controversies and impact of partnership transport.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The current issues of partnership transportation include commuters and commuting society, insurance and registration, maintenance and repairs, safety and development. There is the issue of confronting the daunting challenge posed by global climatic change. The main source of green house gases like carbon dioxide is burning of fossil fuel by either through burning coals, oils, petrol, kerosene etc. Burning of fossil fuel include even idling. Therefore, global warming is caused by emission of green house gases that pollute the atmosphere and this go hand in hand with industrialization. It is due to industrialization that transportation is enhanced by manufacturing of automobiles. Therefore, there must be away of partnership association in combating the consequences of transportation. It is fair for industrialized countries to enhance the issue of mitigating this effect as they are the main cause.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Global warming is one of the negative impacts caused by the gas emitted by automobiles. Mainly the climatic change is usually caused by pollution that affects the ozone layer. Then the ozone layer becomes less effective in controlling the remittance of radiation from the sun. Therefore, the transport board must tackle this problem since they are part of the cause beside industrialization. In addition, this pollution has a major impact on the quality and feasibility of transit-oriented development. The current issue of concern is to mitigate fuel consumption and to avoid accidents caused by reckless driving.   Reckless driving practices can have a negative implication on automobile fuel economy. This project of training drivers can enhance fuel economy because experienced experts would save consumption. This is by using simple techniques like cruise control mechanism, pricing whenever possible, avoiding use of cab appliances, soft and gradual acceleration and progressive shifting. All these mechanisms enhance reduction of speed. Transport sector in collaboration with the traffic police; address this issue by ensuring that transport rules and regulations are adhered to. Transit connectivity plan is improved daily to enhance pediatrician walking; this makes passenger’s movement easy from one movement to another. Goods movement services should be improved to enhance cargo and freight transportation, this include transit expansion program resolution for rail, road, bus and ferry transit projects. Freight movement is essential to any economy and way of life. For example in each year in the US, automobile moved about ten billion tons of freight worth more than 7.5 trillion dollars whereby, the ground freight consumed significant energy and the sector grew as   expected. This is a development issue because over thirty five billion gallons of fuel will increase to about forty five billion by the year 2013. The ground freight industry is large and decentralized; this is because seven million freight trucks and twenty thousand locomotives are in partnership transportation in US and this is not a simple thing. Another development issue is the ongoing activities concerning pedestrians planning strategies, bicycle riders, community-based planning and development they intend to take. Controversies results due to the need of expanding the transport course, this is because expansion might lead to congestion or evacuation of some people from the intended bypass. This program’s goal is to advance the findings of the lifeline transportation network suggestion through collaboration with community organizations, transit agencies and congestion management agencies in order to minimize the dispute. Therefore, the controversies that arise due to congestion are dealt with. Other developmental plans include new means of transport being innovated to cater for the transportation needs of the countries low-income, elderly and disabled populations. For example, the community-based planning program. This program’s goal is to advance the findings of the transportation network system through collaboration Going on, there is this issue about the automotive & transportation practice and development.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   These are the some of the current practices that include the automotive and transportation practice that provides global market research for the completed automobiles. Industrial   analysis, concurrent business research which involves custom market research and consultation, market predicament, management consulting and innovation of new strategies result to emerging technologies that are designed to help transportation sector to address current trends and challenges affecting transportation sector and partnership. Another function is to identify new technologies that can lead to advantageous opportunities for growth. This work involves a   global team of automotive and transportation market research analysts, industry experts, and market  consultants who continuously monitor the automotive and transportation industry including logistics, rail systems, automotive testing, diagnostic sand new chassis technologies. In this partnership transportation, there is training for drivers to be equipped with driving dynamics. This is because, new   commercial vehicles that are being manufactured have these new technologies, for example   telemetric and infotainment, power train ,alternative propulsion, safety and   driving assistance not forgetting warning systems.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The floor is open for those wishing to join the partnership. The advantage is that there is acquiring of freight carrier innovative strategies, freight carrier commitment is enhanced through partnership, freight carrier fleet performance model are available and of course freight carrier benefits of partnership[2]. For example, truck and rail transportation provides a cost-effective means to transport much of America’s freight. Truck and rail fleets can take simple actions to make ground freight more efficient and cleaner for the environment. The following technologies and strategies can help reduce fuel consumption and emissions from freight trucks. First there is idling reduction in the engine mechanism, there is improved aerodynamics in aerial crafting, improved freight logistics. Other current developments include, tire technology that involve automatic tire inflation systems of which tires with wide base are manufactured. In tire inflation system, there is adjustment of the level of tire pressure. This maintains proper tire pressure especially when the automobile is moving; hence facilitating longer service for the tire It is known that tires with wide base can reduce friction and resistance on the road. This would lead to saving consumption of fuel and other fuel related expenditure. Tire technologies improve on reducing accidents by stabilizing the vehicles movement and grasping on the roads. Furthermore, there is production of low-viscosity lubricants that are used in breaks and other movable parts, less viscous artificial and semi-artificial lubricants can reduce friction losses in automobile drive train, emission of gases, and its engine friction. This actually saves the fuel consumption and hence emission of harmful gases.   Going on, synthetic transmission and oil lubricants can raise fuel economy by 0.7 and 2.1 percent in summer and winter respectively. Good news is that by replacing all transmission lubricants with less viscous fluid saves fuel with less or no additional cost. Other development systems are low weight body parts. This is enhanced by sing materials made of aluminum or other lightweight materials. By reducing weight, much oil consumption can be reduced. Actually, the possibility for weight savings is even greater in the automobile. Lastly, there is use of inter modal shipping systems and hybrid power train technology advancement. In the current development systems, several technologies and practices can be used to assist drivers in reducing truck idling. A case study that was performed in one of the automobile firms show that reducing or eliminating prolonged idling of long-transit trucks can save up to one thousands gallons of fuel per truck each year. This would reduce global warming by reducing pollution emissions, and lowering the cost of engine maintenance.   Some idling reduction technologies can minimize fuel consumption through air conditioning.[3] Some of the latest technologies include reduction on fuel consumption; manufacturers have focused considerable attention on implementing new truck tractor aerodynamics systems. By so doing they have achieved significant gains in fuel efficiency and reduction.   To improve efficiency in fuel consumption, improved freight logistics can enhance achieving the goal which include improved operation efficiency, saving fuel and increasing benefits and profits for automobile companies.   Some of the current diplomatic strategies include load scrutiny and matching, more efficient coursing and scheduling of automobiles, and improved working policies. There is use of software to structure more efficient automobile routes. [4] Social, economic and environmental aspect   There is a suggestion for long lasting solutions that would address social aspects, economic aspects, and environmental aspects. The suggestion involves a lifeline transportation program that works with local agencies to improve access to public transit for new entrants to the job market. For example, regional rail plan is helping develop a bay area regional rail plan to improve the current rail system, map out future rail lines and station locations, and integrate passenger and freight from rail sharing on existing tracks. Another example is the suggestion for a smart growth and transportation for livable communities bay area.[5] The communities should embrace the idea by getting a little tender loving care from partnership transportation, in the form of initiatives to foster pedestrian-friendly development and travel options such as walking, bicycling and public transit. [6]   It is visible that Urban Partnership Program proposal to deliver congestion reduction by 2009 through a bold program combing the affiliated parties and experts concerned in tolling, advanced technology, transit and transportation if effective will address some controversies. The current controversies affecting the transportation sector include lack of agreement on terms of scrutiny. There are two controversy terms, that define the impact of partnership transportation i.e. there is technical controversy that defines failure due to decision of an expert appointed by the parties and non-technical controversy that deals with the rules and regulations. The latter, involves bleaching of the contract that involves disputes arrangement on investment. This happened in an oil transportation controversy whereby they wanted the project to be concerned in establishing standards service for the future, rather than examining current controversies about work programmed.   Overcrowding and reliability is also another negative impact caused by partnership transportation. This is a sensitive issue in transportation that require more detailed hearing to solve the pending problems   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Some of these pending issues include, perceived transport problems, factors influencing travel behavior, transport licensing board service provision, infrastructure schemes, partnership approaches and innovative solution. [7]Other development measures currently undertaken include expansion of airports and upgrading to an international level. For example, Durango la Plata county airport is expected to undertake some upgrading changes in the coming years[8]. Some of Strategies to facilitate development could include expansion of the planning area, code requirements for aviation easements, and establishment of requirements for special construction on lands adjacent to the airport. Retrieved from www.laplatacountycolorado.org Conclusion Partnership transport is a broad business operation that currently integrates all areas of work. It has enabled the world to be seen as a global village. In essence, partnership transports easies the work of transportation and collaboration in the sector and other chambers of commerce.   However, the controversies and negative effects should be dealt with immediately when they arise. Safer means of transport should be innovated to avoid negative impact such as pollution to the environment, air pollution and water pollution. Therefore, it is of great importance to associate all stakeholders in transportation sector e.g. oil companies should manufacture lead free fuel to lessen the negative impact caused by the fuel.   Actually, the engine life and service is directly related to the amount of fuel burned. In essence, the reduction of driving speed can minimize the cost of repairing the engine. The maximum automobile driving speeds can be minimized through electronic software engine controlling mechanism, improved driver-training programs, or I house programs that motivate drivers for abiding with the rules and regulations. Almost, all new automobile engines in use today are electronically manipulated and the cost of changing the highest acceleration setting on these engines is to some extent negligible. The stated mechanisms, developments and resolutions to partnership transportation are the currents undertaking towards strengthening of the transport sector.    References: Current developments in airport expansion, retrieved on 25th August 2007, available at www.laplatacountycolorado.org Current undertakings on transportation sector, retrieved on 29th August 2007, available at www. emeraldinsight.com Fleet strategies, retrieved on 29th August 2007, available at http://www.epa.gov/otaq/smartway/smartway_fleets_strategies.htm James A Merchant and Barbara (2005) Transportation: Facilitating partnership transportation, page 7 and 8 New York Transport scrutiny update, retrieved on 25th August 2007, available at www.

Physics Lab Report

Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward, it means he/she speeds up. Consequently, the acceleration should be positive. When the velocity accelerates at a constant rate, the acceleration should remain constant. Therefore, if the participant is moving toward a positive direction and the speed increases, then the acceleration should be positive and constant. Materials * Ticker Tape Machine * Ticker Tape * Tape * Ruler * Pencil * Graph paper Carbon paper Procedure * A piece of Ticker Tape and a Ticker Tape machine were taken. * Ticker Tape machine was plugged in. * One side of the Ticker Tape was attached to the back of a participant. * The other side of the Ticker Tape was inserted through the Ticker Tape machine. * A piece of carbon paper was placed on top of the Ticker Tape and was pinned on the machine. * The machine was started. * The participant sprinted forward. * The machine was stopped. * The used Ticker Tape was collected. * The machine was unplugged. * Using a ruler, a pencil and the Ticker Tape, all the data were recorded on a Data Table. Using the Data Table the position versus time graph and the velocity (instantaneous) versus time graph were plotted. Analysis There were in total of 37 dots recorded on the piece of the Ticker Tape. Every sixth dots represented the 1/60th of one second. Because of the lack of the information, as shown on the Data Table, every third dots were used to expand the amount of data for the more accurate results. Thus, every third dots were used to represent the half of 0. 1 second. Therefore, on both of the position versus time and velocity (instantaneous) versus time graphs, the x-axis value (the time value) went up by 0. 5 seconds. On the position versus time graph, a curved line was drawn due to the increase of the runner’s speed for each 0. 05 seconds. The runner started at 0 second from 0 centimeters and then stopped when the runner’s position was at 0. 65 seconds and 80. 1 centimeters. Also, the curved line on the graph continuously rose upward which meant that the runner never moved backward or slowed down. As evidenced by the velocity (instantaneous) versus time graph, the velocity was the lowest when it was 0 cm/s at 0 second and the highest when it reached positive196 cm/s at 0. 5 seconds. The difference of the velocities was the greatest between 0. 05 seconds and 0. 1 second. Also, the difference was the smallest between 0. 45 seconds and 0. 5 seconds. The two lines of best fit were used for more accuracy due to the scattered dots – which showed the calculated velocities of the specific time intervals – that were plotted on the graph. The first line was illustrated to show the readers the time interval of 0 second to 0. 275 seconds. The second line was used to show the time interval of 0. 2 75 seconds to 0. 65 seconds.Compared to the second line, the first line was drawn steeper due to the larger differences of the velocities of the specific time intervals. For the answer of this report’s question as listed above, when the runner sprinted forward toward a positive direction, the acceleration was able to be calculated from the velocity (instantaneous) versus time graph. In fact, there were two different accelerations during the whole time of 0. 65 seconds. Acceleration could be calculated by measuring the slopes of the velocity (instantaneous) versus time graph which were represented by the two lines of best fit.As shown on the graph, the first line was marked as and the second line was marked as . As seen on the Determination of the Acceleration page of this report, the following mathematical solutions were processed for the solution of the question. * Line * V2 = 134. 2 cm/s * V1 = 0 cm/s * t 2 = 0. 275 s * t 1 = 0 s * Acceleration = (134. 2 cm/s – 0 cm/ s) / (0. 275 s – 0 s) = 488 cm / s2 * Line * V2 = 196 cm/s * V1 = 134. 2 cm/s * t 2 = 0. 65 s * t1 = 0. 275 s * Acceleration = (196 cm/s – 134. 2 cm/s) / (0. 65 s – 0. 275 s) = 165 cm / s2With these two accelerations, it can be analyzed that the runner ran faster during the last 0. 375 seconds than he did during the first 0. 275 seconds. Evaluation This experiment examined the acceleration of a runner when sprinted toward a positive direction. Supported by the evidences and the results of this experiment, one of the two hypotheses stated above was proven false. The runner sped up in a positive direction in a straight line. Hypothetically, the velocity should have been accelerated at a constant rate so that the result could be a constant acceleration.However, according to the data collected, the runner’s first acceleration was 488 cm / s 2 from 0 second to 0. 275 seconds and the second one was 165 cm / s 2 from 0. 275 seconds to 0. 65 seconds. Since there were two different accelerations for 0. 65 seconds, there could not be a constant acceleration. Thus, the prediction of the acceleration being constant was falsified. On the other hand, the other part of the hypothesis was proven true. Theoretically, the acceleration of the runner should be positive because the runner sprinted in a positive direction.As evidenced by the two lines of best fit on the velocity (instantaneous) versus time graph, the slopes were positive due to their upward direction. Hence, since the slopes of the velocity versus time graph represented the person’s acceleration, the runner’s resulting accelerations were positives. To conclude, when the original hypotheses were compared to the calculated results, the first part – â€Å"there should be constant acceleration† – was rejected, on the contrary, the second part – â€Å"there should be a positive acceleration† – was accepted.There were several difficulties when this experiment was performed. For example, the Ticker Tape was so fragile that when the runner started to dart, the tape sometimes got ripped. Thus, it was a challenge to gather enough information to observe and analyze the results. Also, because of the rapid motion of the pin on the Ticker Tape machine, the carbon paper that was placed on top of the Ticker Tape continuously fell off from the machine. In addition, the loud noise produced from the machine created disturbing environment.To improve this lab, advanced technologies such as motion sensors could be used to keep the quiet atmosphere. Lastly, hand-drawn graphs and hand-measured values aren’t always correct. Consequently, they can lead the observers to the wrong conclusions. Therefore, using advanced graphing programs such as Graph 4. 4 could be used for more valid results. To summarize, to avoid miscalculations, advanced technologies and softwares must be used for more precise and accurate products.

The girl on the bus essays

The girl on the bus essays The story by William Sansom is named The girl on the bus. The title of every story is significant because it names the sense for the story. The title of the story introduces the main hero- the girl. It is clear that the girl is in the center of action, which states the cause of the conflict. The words on the bus determine the place of the story. It doesnt mean that the main action takes place exactly on the bus, but it could mean the surrounding of the story. In my opinion, the author by the words on the bus wanted to hint at the changeable setting of the story. The exposition starts with the words Once leaving Haga and finishes with the words Naturally, he felt nervous, frustrated, and dull. The exposition lies in the opening the point of the story. The exposition presents the setting. It presents the place and gives short information about the place and time. The first event takes place in a park in Stockholm, on a winter day. There is no any other description about place; the information about the place is very short. Also the first sentence gives the name to the main hero, who is named by Harry. The event takes place in a park, where Harry met the girl and the beauty of the girl took his breath away. The main action of the exposition is that Harry immediately fell madly in love with her. We find the beginning of the conflict when the girl cast the glance at him, but he never knew whether she saw him at all, or looked past or through him. The exposition is very important because it says about future conflict. We see in that part the position, feelings, emotions of the men, who is waiting for her reaction and attention. To describe the strength of the feelings and emotions of the men the author uses the strong words such madly, alone, nervous...

The Collapse of the Thai Bhat essays

The Collapse of the Thai Bhat essays One of the main similarities between the collapse of the Thai Baht and the collapse of the Korean Won was that they both occurred in the year 1997. This period was a time of great economic crisis, not only for the two countries but also for most of Asia itself. Thailand and Korea emerged as examples of Asias great economies in the mid 1980s and 1990s. But the main reason for the collapse of the two countries currencies was the fact that there was heavy borrowing from banks and foreign investors, which put these Asian companies in debt. For example, from 1990 to 1996 in Thailand, there was an investment boom in commercial and residential property, industrial assets and infrastructure. This led to a great demand in property and this created the real estate in Bangkok to soar. There were many apartments and office buildings going up all over the city. Since the property was so expensive, many property developers had to borrow money from banks. But as long as the value of property rose, the banks were happy to hand out loans to the property companies. Nevertheless, in 1997 the property boom had rocketed so far out of proportion, there was a great excess in both residential and commercial property. This left Bangkok with 365,000 apartment units unoccupied. The once great demand in property had been substituted by an excess supply. Many of Thailands organizations were still purchasing capital equipment from the US, Japan and Europe from loans. This put Thailand at a deficit of 8.1 percent of its gross domestic product. After Somprasong Land Company could not pay an interest on an $80 billion loan, thing started to fall apart. The Thai stock market declined 45 percent from its high in 1996, primarily on concerns that several property companies might be forced into bankruptcy. Many financial institutions, like Financial One, also fell into bankruptcy after being unable to pay back its creditors. ...

5 Peculiarities of the German Language

5 Peculiarities of the German Language You may have heard that German is a difficult and complex language to learn. This is true to some extent; however, much depends on the way the language is taught, the learner’s natural capacity for languages, and the amount of practice dedicated to it. The following peculiarities of the German language should not discourage you from studying German, but simply prepare you for what you will encounter. Remember, German is a very logically structured language, with many fewer exceptions than English. The key to your success in learning German will truly be as this old German adage states: ÃÅ"bung macht den Meister! (or, Practice makes perfect) The Difference Between a German Sausage and a Verb Why are we comparing a sausage to a verb? Simply because German verbs can be chopped and cut up just as  a German sausage can! In German, you can take a verb, chop off the first part, and place it at the end of a sentence. And in actuality, you can even do more to a German verb than what you can do with a sausage: you can insert another â€Å"part† (a.k.a. syllable) in the middle of a verb, add other verbs alongside it and even elongate it. How’s that for flexibility? Of course, there are some rules to this chopping business, which once you understand them, will be easy to apply. German Nouns Every German student loves this particular German-language peculiarity - all nouns are capitalized! This serves as a visual aid for reading comprehension and as a consistent rule in spelling. Further, German pronunciation pretty much follows the way it is written (though you need to know the peculiarities of the German alphabet first, see above), which makes German spelling not very difficult. Now to put a damper to all of this good news: Not all German nouns are inherently nouns and may, therefore, throw off the German writer at first as to whether to capitalize a word or not. For instance, verb infinitives can change into a noun and German adjectives can change into nouns. This role changing of words happens in the English language as well, for example when verbs change into gerunds. German Gender Most would agree, that this is the greatest hurdle of German grammar. Every noun in German is identified by grammatical gender. The der article is placed before masculine nouns, die before feminine nouns and das before neuter nouns. It would be nice if that was all there was to it, but German articles change, along with the endings of German adjectives, adverbs and nouns depending on the grammatical case they are in. For example, let’s take a look at the following sentence: Der Junge gibt der wà ¼tenden Mutter den Ball des Mdchens.(The boy gives to the angry mother the girl’s ball.) In this sentence, der wà ¼tenden Mutter acts as the indirect object, so it is dative; den Ball acts as the direct object, so it is accusative and des Mdchens is in the possessive genitive case. The nominative forms of these words were: die wà ¼tende Mutter; der Ball; das Mdchen. Almost every word was changed in this sentence. One very important point about German grammar gender is that nouns don’t necessarily follow the natural law of gender as we know it. For example, though die Frau (woman) and der Mann (man) are designated feminine and masculine respectively, das Mdchen (girl) is neuter. Mark Twain in his humorous account of â€Å"The Awful German Language† described this German grammar peculiarity in this way: Every noun has a gender, and there is no sense or system in the distribution; so the gender of each must be learned separately and by heart. There is no other way. To do this one has to have a memory like a memorandum-book. In German, a young lady has no sex, while a turnip has. Think what overwrought reverence that shows for the turnip, and what callous disrespect for the girl. See how it looks in print - I translate this from a conversation in one of the best of the German Sunday-school books:Gretchen: Wilhelm, where is the turnip?Wilhelm: She has gone to the kitchen.Gretchen: Where is the accomplished and beautiful English maiden?Wilhelm: It has gone to the opera. However, Mark Twain was wrong when he said that a student has to have â€Å"a memory like a memorandum-book.† There are some strategies that can help a German student figure out which gender a noun has. German Cases In German there are four cases: Der Nominativ (nominative)Der Genitiv/Wesfall (genitive)Der Akkusativ/Wenfall (accusative)Der Dativ/Wemfall (dative) Though all cases are important, the accusative and dative cases are the most widely used and should be learned first. There is a grammatical trend especially orally to use the genitive case less and less and replace it with the dative in certain contexts. Articles and other words are declined in various ways, depending on gender and grammatical case. The German Alphabet The German alphabet has a few differences from the English language. The very first (and perhaps most important) thing you need to know about the German alphabet is that there are more than twenty-six letters in the German alphabet.

Ecology - tasks (1-2-3-4) - Assignment Example The local economy grows because of buying from the local farmers, and this still keeps them into the business. Buying local food means that food is not travelling long distances by trucks, ships, planes and trains, which all use energy and thus spew pollution the results to global warming and unhealthy quality of fair. Such pollutions have effects on our health that reflected in high rates of asthma besides other respiratory symptoms. In addition, consuming local foods gives the benefit the chefs call better and fresher tasting food on your table. Moreover, food miles represent that distance your food travels from to the point where it is eaten. According the World Watch Institute, the transportation of food has been a fast-growing source of greenhouse gas emissions e.g. carbon dioxide thus leading to climatic change. The result of this is that, a basic diet of imported products uses four times the energy and then produces four times the emissions of an equivalent domestic diet. II. Eat locally made foods. The local foodstuffs reduce the amount of emissions into the air due to shipping and other modes of transportation. Eating local foods maximizes on the security and freshness and finally supports the local economy. V. Buy products that are organic and local. Produce having undergone treatment of pesticides are good for the environment and ones-self. The local foodstuffs use less gas to get from the farm to your plate, and since the distance travelled is shorter, they reach your plate while still fresh. 1.

Discussion - Essay Example The quality of any research findings depends on the source of information applied and therefore the quality of the source matters (Arlene, 16). Your choice for the second question implies your concern on the quality of research work and the common mistakes that researchers commit. Apart from being credible, sources should also be authentic, reliable, and authoritative. In your comment, you have identified Wikipedia and about.com as some of the invalid research sources. They serve as good examples of sources that lack authority. Probably you could have added the fact that most students are enticed into using these sources in their research papers as opposed to credible source such as books and peer reviewed journals. From your comment, you seem to have the right facts about research and research work. Your comments have probably changed my attitude towards credibility of research and I fully concur with you. It is interesting to note that researchers perform massive work in finding of research information but lack time to research for their sources. They end up getting a lot of information that may be of little use. In your comment, you have highlighted some principles of evaluating the credibility of a source and I recommend them to all existing and potential researchers. In addition, I would suggest that researchers present their research work to relevant authorities for evaluation before releasing the same to the intended audience. A good example is peer reviewed journal articles, which are scrutinized thoroughly for authenticity and

Fashion Merchandising Essay Example | Topics and Well Written Essays - 1750 words

Fashion Merchandising - Essay Example The paper "Fashion Merchandising" analyzes The Ethics of Counterfeiting in the Fashion Industry. According to (Hilton, Chong Ju and Chen 345-354), the ethical issues of counterfeiting in fashion merchandizing are rooted among the fashion industry itself. This global issue can be analyzed by the statistical analysis which shows that the counterfeit market is worth $350 billion (Turner). This problem is comparatively increased in Western countries because of the non-involvement of legal system in designing sector of fashion. According to Skov, counterfeit is also a legal and economic issue which results into â€Å"misleading the consumer into believing that the goods that are presented are the real thing. Counterfeiting is done on the basis of â€Å"credence goods† which are defined as: â€Å"Goods whose quality is difï ¬ cult to assess before or after purchase and use. According to (Turner), â€Å"Credence goods are what are most copied because their value can only be dete rmined by the credence or faith given to them by others, therefore they are easily exploitable. These items are usually of medium quality that has a high-perceived value, which can be easily copied. In order to elaborate the importance of credence in fashion industry, let’s consider the nature of fashion world. According to (Hilton, Chong Ju and Chen 345-354), â€Å"credibility† is the main entity which lay the basis of fashion industry. This credibility is gained through buyer and manufacturer. This credibility is majorly gained through fashion â€Å"indicators†.

Being Black in the 1950's Essay Example | Topics and Well Written Essays - 1000 words

Being Black in the 1950's - Essay Example Being black in the 1950s meant that one had to cope with a discriminative education sector. Blacks had to travel long distances to school, which were scarce and were often poorly constructed, lacked books and other equipments, and had small classes that were crowded and that were taught by few unqualified teachers who had to be black. The whites however had many well-built and well-equipped schools taught by qualified white teachers. A Black man graduating from the aforementioned schools would therefore be unable to compete for opportunities with the White man and therefore the systems was partly designed to ensure that the White man remained superior to the Black man. A Black man would not get a good job and whenever he got one, he was given lower salaries than the Whites were. A survey done in 1950 showed that a Black man would get almost half of the Whites’ salary for the same work and position. This discrimination was extended the public sector and political offices â€⠀œ the white had put laws and practices to deter a black man from ascending to power or being elected. Such measures would include paying of taxes before being registered to vote and since Blacks were poor, they could not afford this and many were therefore locked out. There was also an illiteracy test for people who wished to be registered as voters. This locked out many black men who could not afford education due to poverty and this minimized the chances of black men voting their fellow blacks in. This meant that the blacks had no representation and therefore, they were not involved in making laws. The white man therefore made laws that did not favor the black man. A Black man also endured racism even in public places. For instance, he could not use the same public utilities as the White – there were public toilets for the Whites and others for the blacks. A black man could not enter the same joints and restaurants with the whites. He had to endure poor and low cost facili ties and utilities wherever he went. The transport industry is another place where the black man was discriminated. The black man, as if to affirm his position in the society, had to sit at the back rows of buses with their seats marked â€Å"colored people.† In some states like Alabama, there was a law that whenever a white man lacked a seat, a seated black man was supposed to give his seat to the white. Any black who dared oppose these rules was taken to court and subsequently jailed, as it was the case with Rosa Parks, who refused to give up her seat to a white person. She was jailed, sparkling the blacks’ bus boycott of 1955. A black man was subject to torture, intimidation and oppression whenever he tried to resist any discriminative law or tried to liberate himself. The whites had formed fear-inflicting groups like Ku Klux KIA, which attacked the opposing blacks, tortured them and scared them while concealing their identity. They would burn a black man’s h ouse, destroy their properties or even kill them. In 1955, the whites burned and destroyed the house and property of Martin Luther while he led the bus boycott. He himself was incarcerated. Earlier in the year 1954 when the blacks’ Supreme Court declared that segregation in schools illegal, the group and some youths organized attacks and demonstration to scare off any black man who dared set foot in a whites’ school. Many were scared away and only the brave remained.

Assigment - Assignment Example There are a number of criteria used to determine who will come first in the waiting list, which might help us solve the issue the doctor is faced with. The patients ability to pay for the organ is what is considered first. A heart is treated like a scarce commodity because it is hard to find and it is are also more valuable than anything else because of its ability to save someones life (Perry, 2013). A scarce commodity, which is vital for someone to continue living, is certainly not a luxury, thus the reason why the highest bidder is considered first. The second factor is the preference of the donor or kin. In short, this is who the heart donor decides will be the recipient of the heart (Perry, 2013). For example, a white racist might say that their heart should not be given to an African or a Muslim might say that their heart only goes to a fellow Muslim. The third factor is that the transplant might favor the donors religion or citizenship. This is done in support of the taxpayers money channeled to the endeavor (Perry, 2013). However, in the cases provided, the second and third factors might not apply because we are not told the religion or citizenship of the donor and we are also not told whether the donor had racist views. The fourth factor to be taken into consideration is the need of the patient (Perry, 2013). The need of the patient, the extent to which the transplant will help the patient, is also another vital factor. However, in most cases, it is the senior doctors who decide whether the patients need is that significant (Perry, 2013). Thus, in this case, the doctor might not be very influential in deciding which patient mostly needs to transplant. Apart from their needs, there are also the benefits to the recipients. They consider factors such as age, overall health, ability to obey the regimen or anti-rejection drugs and also the patients support system (Perry, 2013). These can apply in our case because some of the clients

Federal prison tour Essay Example | Topics and Well Written Essays - 500 words

Federal prison tour - Essay Example We however did not visit the whole prison but instead visited the facility containing inmates of smaller crimes and were almost being released. The prison is divided into various different sections named in alphabetical order. Each section holds different types of prisoners. It has a library used to conduct researches, especially for those who want to conduct legal researches and prepare legal documents, and also as a study hub for those prisoners interested in reading. Besides, the library provides unlimited resources for those prisoners undertaking educational programs such as high school diploma for those who did not graduate through high school. Non-English speaking prisoners are required to take English classes and the library comes in handy in this case. The use of the library is generally encouraged since reading combined with recreational activities hugely contributes to an inmate leading a healthy lifestyle as well as developing healthy habits. Talking about recreational activities, like most prisons in the country, the federal prison of Terre Haut provides entertainment to its inmates. The prison has established various entertainment spots all over the facility, for prisoners and guards alike. It is believed that the entertainment alleviates the risk of high-stress levels in inmates and thus reducing suicidal tendencies within the prisoners. One of the most sensitive department in prisons and correctional institutions in the world is always the food department. This prison is no exception. Contrary to what many people may believe, the federal prison in Terre Haut has relatively nice and clean restaurants. The kitchen and food storage areas are not any different. High hygienic standards are adhered to by the kitchen staff in a bid to keep the inmates fine and healthy. Within the facility is a prison textile factory that manufactures blankets and bedspreads.

The Influence of the Age of Enlightenment Essay Example for Free

The Influence of the Age of Enlightenment Essay The Age of Enlightenment is characterised by the 17th and 18th centuries in Europe and America. During this time, developments in philosophy, science, art, religion, and politics occurred along with the growing doubt in the teachings of the Church and even the existence of God. Philosophers such as Descartes, Bacon, and Luther promoted the search for truth based on the application of human reason. In addition, correct method of reasoning was mostly applied in the sciences and mathematics to understand the world, and explain phenomena. Such reasoning may have led Darwin and his followers to the development of scientific world theories such as the evolution later on. Among the forerunners of the period, Thomas Hobbes (1588-1679) characterised mans motives as reflections of his own pleasure and pain. He is most famous for his concept of the social contract which suggests that a society be run by a single ruler who controls everything and has power over every man, including their motives and impulses. In addition, John Locke (1632-1704) became very famous with his belief that the human mind is a tabula rasa or a black slate, which is opposed to the Puritan belief that each individual is born with original sin and is responsible for social injustice. Voltaire (1694-1778), a prominent French social critic, essayist, poet, playwright and philosopher during his time offered the society his views which later served as inspiration to the French revolutionists. In particular, his views on religion challenged the Catholic Church in claiming that the churchs dogmas are incorrect and misleading. He further believed that religion alone cannot save a man. His criticism of the French government in favor of its English counterpart led to his exile in 1734. Jean-Jacques Rousseau (1712-1778) was also one prominent philosopher during the Age of Enlightenment. He attracted public attention with his rejection of conformity to the contemporary society. In doing so, he clearly pronounced his call for reformation in general. In particular, he upheld the moral and legal equality of man, the sovereignty of the people, and the authority of the general will'[1]. Further to the application of human reason, the period saw the rise of sceptics, encyclopedists, and deists who shaped the mindset of the people, and affected much their way of life, including the arts produced during the time. Visual artists of the 1700s were either preoccupied or limited to Rococo especially women who struggled much to establish their niche. Rococo paintings produced during this time often dealt with human and still life subjects, and emphasised airy grace and refined pleasure'[2] found in portrayal of beauty in delicate fabrics, jewelry, porcelains, etc. Also, wooded scenes, artful dances, women, and portraiture specially nude ones were very common. Among the renowned visual artists during this time was Antoine Watteau (1684-1721). In his works, we can note that the search of man for reason during this time was so intense. Specifically in Pierrot, we see the subject flanked by four other figures—the Doctor on his donkey, Là ©andre, Isabelle and the Capitaine'[3]which signify the relation of man with other individuals thus complementing his existence. Likewise, in his other paintings, we see the portrayal of the compete beauty and drama of life. Francis Boucher (1703-1770) dealt on pastoral subjects, and women including the Virgin and the goddess Venus. Although his works still mirror Italian influence, we can see the development of a reformation from the background of the subjects in his works. Jean Fragonard (1732-1806), another Rococo painter expressed vividly his times yearning for reason in that his subjects were seen to be either reading or writing. Also, his work, A Young Girl Reading is representative of the Baroque style that flourished after Rococo. The artists during the early 17th century mostly exhibited Italian influence and a lot of them dealt on   Greek mythology. However, from the backdrop of the paintings we studied, a foreshadowing of the neoclassical art could be established. Sculptors during the enlightenment include Jean Antoine Houdon (1741-1828) who was the best portrait sculptor of his time and perhaps of all time'[4]. His legacies include portraits of the most important figures in his time including Voltaire, George Washington, Diderot, Franklin, etc. Ideally representing his period were Houdons woks which reveal the very essential quality of man—his reason which we can note in   expression of his subjects—from the pupils of their eyes, the robustness of their chest, and the lines on their flesh. Overall, he focused on people as his subjects, and revealed eloquence and greatness expressed in brows, hair, and facial lines. In Flayed Man (1767), Houdon clearly shows us how the science of anatomy can be combined with arts. Neoclassicism gave way to the expression of reason, thus artists found more themes to express their views and style. Literary writings which emanated during this time include different genres such as prose, poetry, drama, novel, and exposition.   Among the said genres, the novel became the major literary vehicle for writers specially for women authors, first in France, then in England. In addition, Neoclassicism voiced the writers disdain for irrational customs and outworn institutions as evident in the satirical masterpieces of Candide (1759) and Voltaire. Among the essays produced during this time, satyrs were the most common, as writers constantly searched for ways to mirror the government and society. Philosophes flourished specially in France, with Charles de Montesquieu as one of the earliest representations of the movement. Also, a well known author was Alexander Pope who wrote   The Essay on Criticism (1711) in which he argued that a work must be evaluated according to the purpose it serves and the writers intention in it. Among the famous novels produced, Robinson Crusoe by Daniel Defoe (1659-1731) chiefly represents the ideals made popular by the philosophes during this period. Primarily, the idea of Hobbes of going back to the primitive life is shown, which is victoriously survived by the protagonist, the protest of Voltaire and other deists against religion, and the constant search for meaning as evident in Crusoes journey to the Indies. Other novels written include Jonathan Swifts Gullivers Travels, and Samuel Richardsons Clarissa. The famous names of Johann Sebastian Bach (1685-1750), George Frideric Handel (1685-1759) , Wolfgang Amadeus Mozart (1756-1791), and Ludwig Van Beethoven (1770-1827) occupy the music arena during this period. From the works of Bach to those of Beethoven, we can sense a transformation in style and form. The early classical works specifically those of Handel were mostly grand operas and cantatas, while those of his successors were mostly symphonies and piano concertos. Although a lot of famous artists were considerably men, the arts produced during the Age of Enlightenment also recognised the image of the women in the society. Along with this, the philosophers, writers, and critics of this time considered the situation of the middle class in their writings, and criticised slavery and oppression. The period saw the rise of reform in the attitude of the people, and gave birth to French revolution and other revolutionary theories.

Water Soluble Vitamins for Poultry

Water Soluble Vitamins for Poultry The vitamins are a very important class of the nutrients. They play various important roles in the life cycle of any living-being. The absence or deficiency of the vitamins in poultry causes serious problems. The water soluble vitamins are very important sub-class of vitamins. In the poultry which can not synthesize these vitamins in their body these should be provided in the diets means these are dietary essential. The inclusion of the water soluble vitamins accurately, according to the needs of birds, production stage, physiological state of the birds and environmental conditions is very necessary to avoid the problems and to gain maximum performance because these vitamins are required by the birds in many systems including energy metabolism, growth, proper blood flow, development of skeleton, compensation of the stress, egg production, fertility, anti-oxidants for semen and proper development and viability of the growing embryos. It means these are not only important for current b irds but also their provision in an accurate way will ensure the next generation of the birds. Key words: roles, water soluble vitamins, poultry. Introduction The term vitamin was first used in 1912. Vitamins are a group of complex organic compounds which are present in minute amounts in natural feedstuffs. These are required for normal metabolism and the deficiency of these compounds in the feed causes deficiency diseases. The vitamins are divided into two groups depending upon their solubility i.e. Fat soluble vitamins which include Vitamin A, D, E and K. Water soluble vitamins which are Vitamin B-complex and vitamin C. The names, synonyms and the two classes i.e. fat and water soluble can be summarized as: Vitamin names Synonyms Fat soluble Vitamin A1 Retinol, retinal, retinoic acid Vitamin A2 Dehydroretinol Vitamin D2 Ergocalciferol Vitamin D3 Cholecalciferol Vitamin E Tocopherol, tocotrienols Vitamin K1 Phylloquinone Vitamin K2 Menaquinone Vitamin K3 Menadione Water soluble Thiamin Vitamin B1 Riboflavin Vitamin B2 Niacin Vitamin PP, Vitamin B3 Vitamin B6 Pyridoxol, pyridoxal, pyridoxamine Pantothenic acid Vitamin B5 Biotin Vitamin H, vitamin B8 Folic acid Folacin, folate, Vitamin M, Vitamin Bc, Vitamin B9 Vitamin B12 Cobalamin Choline Gossypine Vitamin C Ascorbic acid (Adopted from McDowell, 2004) Poultry and other monogastric animals are dependent on dietary sources of vitamins to a much greater degree than are ruminants. It is considered that animals with fully functional rumen can not suffer from a deficiency of vitamin B-complex. Vitamin B12 is unique in that it occurs in plant tissues as a result of microbial synthesis (McDowell, 2004). Thiamin (B1) is required to control appetite and reduces death rate, Riboflavin (B2) is responsible to control curly-toe paralysis, proper growth and proper egg production, Pantothenic acid(B5) is necessary for controlling dermatitis and improper lesions on the mouth and feet, Niacin (B3) is involved in proper confirmation of legs, tongue and mouth cavity, Choline ensures proper growth and proper egg production, Vitamin B12 is required to control anemia and to control early embryonic death, Folic acid (B9) is required for proper growth, controlling of anemia, proper feathering and proper egg production, Biotin (B8) is required to control d ermatitis o feet, around eyes and beak and Ascorbic acid(vitamin C) is required to normal growth and development, growth and repair of tissues, formation of collagen, cartilage, bones, avoid stresses and wound healing (Unknown, 2002). Vitamin C (vit C) is a water soluble antioxidant found in cytosol and extracellular fluids and it can directly scavenge super oxide hydroxyl radicals and single oxygen species (Clarkson and Thompson, 2000). It is thought to exert its effects on the immune system through the enhancement of neutrophil production and through protection of the cell against super oxide radical damage (Bendich et al., 1986). Under normal conditions birds can synthesize sufficient amounts of vit C (Roy and Guha, 1958), however in the stress conditions birds may require an external source of vit C (Meade S.M. 2004) to provide non-specific resistance against infections and overcome stress and therefore improving productivity (Pardue and Thaxton, 1985). The phagocyte activity is enhanced in the presence of vit C. There is a higher quantity of the superoxides found in the phagocytes when sufficient amounts of vit C are found and further increase in the level of vit C further increases the amount of free radicals in phagocytes (Scarpa et al., 1983; Som et al., 1983). Viral infections have been shown to cause a depletion of leukocyte ascorbate, which resulted in varying degrees of non-specific immunosuppression and a reduction in serum vit C concentration (Thomas and Holt, 1978; Bendich et al., 1986). The role of vit C in controlling of stress has been documented many a times. There was a proof that by providing external vit C source at a rate of 330ppm the blood levels of vit C are elevated (Nestor et al., 1972). Another study showed that a 1000ppm adding of vit C reduces exogenous cortisol related immunosuppression. Some studies have also reported that vit C decreases heat shock protein 70 and plasma corticosterone response in chicken subjected to cyclic heat stress (Mahmoud et al., 2003, 2004). Vitamin C supplementation in feed or water can also reduce the sensation of fear in the birds (Jones, R. B., 1996). Pardue and Thaxton (1986) documented the effects of supplementation with vit C on a number of characteristics including growth, reproductive performance, immunosuppression and mortality. It was also documented by Satterlee et al., 1989; Kutlu and Forbes, 1993a; McKee and Harrison, 1995) Poultry under intensive production systems are particularly susceptible to vit deficiencies so to avoid this poultry feeds are supplemented normally with B2, niacin, pantothenic acid, B12 and choline out of water soluble vitamins (Scott et all. 1982). It is to be noted that Thiamin, vitamin B6, biotin and folacin are mostly present in adequate quantities in the major ingredients such as corn-soybean meal-based diets and poultry can normally produce a sufficient amount of ascorbic acid by its own (McDowell, L. R. 2004). Vitamin needs of new strains developed for improved production are higher. Leg problems seen in fast growing strains of broilers can be corrected in part by higher levels of biotin, folacin, niacin and choline (Roche 1979). Stress and disease conditions in animals may increase the basic requirement for certain vitamins. Nutrient levels that are adequate for growth, feed efficiency, gestation and lactation may not be adequate for normal immunity and for maximizing the a nimals resistance to disease (Cunha 1985; Nockels et al. 1996). Diseases and microorganisms affecting the gastro intestinal tract reduce the absorption as well as the production of vitamins also the conditions affecting the G.I.T. cause a reduction in vitamin production and absorption i.e. diarrhea and vomiting (McDowell, L.R., 2004). Mycotoxins and internal bleeding in poultry also causes a reduced efficiency of vitamins (McDowell, L.R., 2004). Vitamin antagonists (antimetabolites) interfere with the activity of various vitamins (Oldsfield, 1987). Under commercial production a higher level of the vitamins is helpful for optimum production and performance this also helps in achieving best growth rates, feed utilization and health and in part also helps to increase body reserves (Coelho, 1996). The ascorbic acid acts as an antioxidant for the avian spermatozoa (Surai et all, 2001). Ascorbic acid supplementation enhances the ejaculation qualities of male fowl (Surai et all, 2001). In the hot and dry season offering the cold water supplemented with ascorbic acid increases weight gain and spleen but it will also cause a reduced size of wings (Abioja, et all, 2011). Classes of B-Complex Based on the functions the B-complex can be categorized into 3 classes, however some of the members fall into more than one class; Energy releasing Thiamine (B1), Riboflavin (B2), Niacin (B3), Pantothenic acid (B5), Piroxidine (B6), and Biotin. Hematopoietic Folic acid (B9), Cyanocobalamin (B12), Pantothenic acid (B5), and Piroxidine (B6). Other Thiamine (B1), Niacin (B3), Piroxidine (B6), Folic acid (B9), and Cyanocobalamin (B12). (Wilson, G. V.) Vitamin B-complex deficiencies Deficiency arises due to inadequate supplies of the vitamins and the signs develop over a time period. So if the vitamin levels provided are lower than the required levels then the classical deficiency signs will be seen in the birds. Generally the young and growing chicks are more prone to vitamin deficiencies and the developing embryo is the best model showing deficiencies of vitamins. Problems due to the B-complex deficiency arise quite abruptly and often seen in 5-7 days because there is a little storage of these in the body (Leeson, S. and J. D. Summers, 2001). In the researches carried out on poultry of different age groups it was shown that a deficiency in the availability of Thiamine (B1) caused a loss of appetite and increased death ratios (Poultry Health Services, 2009). Leeson, S. and J. D. Summers, 2001 stated that polyneuritis in the birds shows the later stages of thiamine deficiency which may arise due to the build up of the intermediates of carbohydrate metabolism. In mature birds it is seen approximately 3 weeks after they are being fed a thiamine deficient feed. Poultry may also suffer from neuromuscular problems, resulting in impaired digestion, general weakness, star gazing and frequent convulsions (Leeson, S. and J. D. Summers, 2001). A deficiency in the availability of Riboflavin (B2) caused increased occurrence in the curly toe paralysis, poor growth and poor egg production (Poultry Health Services, 2009). Many tissues especially epithelium and myelin sheath are affected due to feeding of a feed which is d4eficient in riboflavin and on postmortem the characteristic sign of riboflavin deficiency is marked enlargement of the sciatic and brachial nerve sheath with the sciatic nerve showing the most pronounced effects (Leeson, S. and J. D. Summers, 2001). A feeding programme with a deficient amount of Pantothenic acid (B5) is evident as occurrence of dermatitis and lesions on mouth and feet (Poultry Health Services, 2009). According to Leeson, S. and J. D. Summers, 2001 the major lesions due to deficiency of pantothenic acid involve nervous system, the adrenal cortex and the skin. Niacin (B3) deficiency is shown by bowed legs and inflammation of tongue and mouth cavity (Poultry Health Services, 2009). Leeson, S. and J. D. Summers, 2001 report that niacin deficiency is characterized by severe metabolic disorders of skin and digestive organs, signs being the loss of appetite, retarded growth, general weakness and diarrhea in the birds. A feeding programme having deficiency of pyridoxine (B6) is characterized by retarded growth, dermatitis, convulsions, anemia and there may also be reduced nitrogen retention (Leeson, S. and J. D. Summers, 2001). Choline deficiency is evident from poor growth, fatty liver, decreased egg production (Poultry Health Services, 2009). Leeson, S. and J. D. Summers, 2001 report the deficiency of choline in growing chicks is evident from poor growth and perosis. Cobalamin (B12) deficiency is shown by cases of anaemia, poor growth, embryonic mortality (Poultry Health Services, 2009). According to Leeson, S. and J. D. Summers, 2001 a deficiency of B12 in growing chicks showed decreased weight gain, decreased feed intake, poor feathering and poor nervous system. Folic acid (B9) deficiency is evident from poor growth, anaemia, poor feathering and poor egg production (Poultry Health Services, 2009). A deficiency of folic acid in the experimental birds caused macrocytic (megaloblastic) anemia and leukopenia i.e. reduced white blood cells (Leeson, S. and J. D. Summers, 2001). Biotin (B8) deficiency increases the dermatitis on feet and skin around eyes and beak (Unknown, 2004; Poultry Health Services, 2009; Roche 1979; Leeson, S. and J. D. Summers, 2001). The diseases and problem seen due to deficiencies of the water soluble vitamins in poultry can be summarized in the following table Deficient vitamin: Thiamine (B1) Evident deficiency signs: loss of appetite increased death ratios polyneuritis impaired digestion general weakness star gazing frequent convulsions Deficient vitamin:  Riboflavin (B2) Evident deficiency signs: curly toe paralysis poor growth poor egg production affected epithelium and myelin sheath Deficient vitamin:  Pantothenic acid (B5) Evident deficiency signs: dermatitis lesions on mouth and feet Deficient vitamin:  Niacin (B3) Evident deficiency signs: bowed legs inflammation of tongue and mouth cavity Loss of appetite retarded growth general weakness diarrhea Deficient vitamin:  pyridoxine (B6) Evident deficiency signs: retarded growth dermatitis convulsions anemia Choline poor growth fatty liver decreased egg production perosis Deficient vitamin:  Cobalamin (B12) Evident deficiency signs: anaemia poor growth embryonic mortality Decreased weight gain decreased feed intake poor feathering Poor nervous system. Deficient vitamin:  Folic acid (B9) Evident deficiency signs: poor growth anaemia poor feathering poor egg production leukopenia Deficient vitamin:  Biotin (B8) Evident deficiency signs: dermatitis on feet and skin around eyes and beak (Poultry Health Services, 2009; Roche 1979; Leeson, S. and J. D. Summers, 2001) Role of water soluble vitamins as Co-enzymes Riboflavin or vitamin B2 is a prosthetic part of over a dozen enzymes in the animal body including cytochromes reductase, lipoamide dehydrogenase, xanthine oxidase, L- and d-amino acid oxidase, histaminase and others all of which are vital for oxidation-reduction reactions involved in cell respiration (Leeson, S. and J. D. Summers, 2001). Niacin or nicotinic acid is important in more than 100 different enzymatic reactions (Rasmusson R.) It is the vitamin component in two important enzymes i.e. nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) reported by Leeson, S. and J. D. Summers, 2001. Pantothenic acid (B5) is the prosthetic group of coenzyme A, an important coenzyme involved in many reversible acetylation reactions in carbohydrate, fat and amino acid metabolism (Leeson, S. and J. D. Summers, 2001). Biotin (B8) is an essential co-enzyme in carbohydrate, fat and protein metabolism (Leeson, S. and J. D. Summers, 2001). Vitamin B12 is an essential part of several enzyme systems, with most reactions involving the synthesis of one carbon units i.e. methyl groups (Leeson, S. and J. D. Summers, 2001). Role of Ascorbic acid (vitamin C) in birds under stressful conditions The efficacy of supplementing birds with vitamin C under stressful conditions depends upon its ability to elevate plasma vitamin C (Pardue et al., 1984). Nestor et al., (1972) reported that 330ppm vitamin C elevated blood vitamin C. Pardue et al., (1984) reported that vitamin C supplementation at a rate of 250ppm increased plasma vitamin C concentrations in broilers. But Sell et all in 1997 found that 300 mg/kg vitamin C was unable to increase plasma vitamin C levels. Kolb (1984) strongly suggested that supplemental vitamin C should be provided in poultry and livestock diets as a stress alleviator. Hill and Garren (1958) agreed and stated that vitamin C was an essential nutrient in chickens experiencing stress. Vitamin C supplementation at 300 mg/kg was able to decrease plasma corticosterone in stressed birds. These responses are supported by research suggesting that vitamin C suppresses adrenocortical steroidogenesis and depresses plasma corticosterone levels, therefore limiting som e of the deleterious responses associated with stress and delays the depletion of steroid hormone precursors (Pardue et al., 1985; Gross, 1992; Kutlu and Forbes, 1993). The action of vitamin C on adrenal steroidogenesis is associated with its ability to inhibit adrenal steroid hydroxylating enzymes (Kitabchi, 1967). Supplementation with 300 mg/kg of ascorbic acid resulted in a significant increase in plasma vitamin C throughout the experiment when compared to the Un-Supplemented birds (Meade, S.M., 2004). There is limited research examining the effects of vitamin C on lymphocyte subset populations in chickens. However, those experiments that have been demonstrated the effects of vitamin C on lymphocyte populations in association with disease or vaccination (Wu et al., 2000). The effect of dietary vitamin C supplementation is still controversial however vitamin C supplementation at 300 mg/kg alleviated stress-induced affects (Meade, S.M., 2004). These physiological and immunological findings suggest that vitamin C may be an anti-stress agent and may be an essential nutrient in poultry when poults are subjected to stressful conditions (Meade, S.M., 2004). Ascorbic acid as an anti oxidant for avian spermatozoa Ascorbic acid or vitamin c is water soluble anti oxidant present at high molar concentrations in spermatozoa and seminal plasma in a large number of animals. In poultry its concentration in semen averages 210 +-16.4microM (Surai et all 1986b). On a molar basis this concentration was more than 2.5 times higher than glutathione and more than 100 fold higher than alpha-tocopherol. Ascorbic acid was found almost equally distributed between spermatozoa and seminal plasma (Surai et all 1986b). This data was very useful in the development of an idea that vit. C plays an important role as a water soluble anti oxidant in the avian seminal plasma (Surai et all, 2001). Ascorbic acid effect on ejaculation quality of male Fowl Monsi and Onitchi in 1991 reported that fowl males housed under hot and humid conditions and supplemented with ascorbic acid showed a better overall ejaculation quality i.e. semen volume, motile sperm proportion and sperm number per ejaculate. The reported ascorbic acid supplementation level was 500mg/kg. However sperm motility was not affected. Dietary supplementations of ascorbic acid had the effects on semen of rainbow trout reflected by increased sperm motility and decreased decline in fertilizing capacity of spermatozoa after storage (Ciereszko and Dabrowski, 2000). A protective role of ascorbic acid in maintaining the sperm quality was also reported by Ciereszko and Dabrowski in 1996. However the low dietary levels of vitamin E and C (ascorbic acid) had no effects on the spermatozoa in mice rather the increased and higher supplementary levels decreased the number of spermatozoa/mg epididymis and increased the percentage of spermatozoa with misshapen heads (Ten et all, 1997). Role of ascorbic acid in weight gain A study was carried out in SW Nigeria on a group of broiler chicken. The birds were divided into four groups after the age of three weeks. A group was given cold water without any ascorbic acid and other group was given cold water with supplementation of ascorbic acid. Similarly two groups were made for normal unchilled water with and without ascorbic acid provision. The results of study showed a marked superior growth of breast meat and spleen in the group provided with cold water and ascorbic acid. However there was no affect of ascorbic acid supplementation on the growth parameters of the birds in any of the four groups. In addition there was a decreased wing length seen in these birds. The reason for this phenomenon to happen is that in hot climatic conditions a lot of the energy is wasted in panting and when cold water is provided the birds feel comfort and there is less panting seen. Also in stress corticosteroids are released which further decrease the weight gain. By providin g cold water these both conditions are avoided so better results are obtained. The cold water resulted in an overall more weight gain weekly and finally more live weight however decreased wing length, the vitamin c had no effect on the growth however it increased the breast meat and the spleen in birds, (Abioja, et all, 2011). Role of water soluble vitamins in Energy metabolism The transformation of dietary energy sources, such as carbohydrates, fats and proteins into cellular energy in the form of ATP requires several micronutrients as coenzymes and cofactors of enzymatic reactions, as structural components of enzymes and mitochondrial cytochromes, and as active electron and proton carriers in the ATP-generating respiratory chain(Groff et all, 1996, Depeint et all, 2006): (i) thiamine pyrophosphate (TPP; vitamin B1), CoA (containing pantothenic acid), flavin mononucleotide (FMN; derived from vitamin B2), flavin adenine dinucleotide (FAD; derived from vitamin B2) and nicotinamide adenine dinucleotide (NAD; derived from nicotinamide) are involved in the Krebs cycle and complexes I and II of the respiratory chain; (ii) biotin, CoA and FAD are involved in haem biosynthesis, which is an essential part of the cytochromes and important for the latter part of the mitochondrial respiratory chain; (iii) succinyl-CoA can feed into either the respiratory chain or the Krebs cycle depending on the needs of the cell. Depeint et all, in 2006 confirmed the essential role of vitamins B6, B12 and folate in maintaining the mitochondrial one-carbon transfer cycles by regulating mitochondrial enzymes. The same authors also emphasized the essential role of the B vitamin family in maintaining mitochondrial energy metabolism and how mitochondria in their role as the cellular organelles responsible for energy metabolism are compromised by a deficiency of any B vitamin (Depeint et all, 2006). Table given here summarizes the present state of knowledge with regard to the role or roles of individual water soluble vitamins in energy metabolism (adopted from Institute of medicine, 1998). Vitamins Function in energy metabolism Thiamine (B1) Essential cofactor in the conversion of carbohydrates to energy. Needed for normal muscle function, including the heart muscle. Involved in oxidative carboxylation reactions, which also require manganese ions. Riboflavin (B2) As a cofactor in the mitochondrial respiratory chain, helps in the release of energy from foods. Component of the main coenzymes FAD and FMN. Nicotinic acid, niacin (B3) As a cofactor in the mitochondrial respiratory chain, helps in the release of energy from foods. Transformed into NAD and NADP, which play a key role in oxidation -reduction reactions in all cells. Pyridoxine (B6) Helps in the release of energy from foods. Used as a cofactor by nearly 100 enzymatic reactions, mainly in protein and amino acid metabolism. Vitamin B12 Essential for metabolism of fats and carbohydrates and the synthesis of proteins. Interacts with folic acid metabolism. Biotin As a cofactor, involved in metabolism of fatty acids, amino acids and utilization of B vitamins. Pantothenic acid Plays an essential role in the Krebs cycle. Component of coenzyme A. Vitamin C Essential for synthesis of carnitine (transports long-chain fatty acids into  (Ascorbic acid) mitochondria) and the catecholamines, adrenaline and noradrenaline. Ascorbic acid facilitates transport and uptake of non-haem iron at the mucosa, the reduction of folic acid intermediates, and the synthesis of cortisol. Potent antioxidant. Folic acid Folates function as a family of cofactors that carry one-carbon (C1) units required for the synthesis of thymidylate, purines and methionine, and required for other methylation reactions. Folate is essential for metabolic pathways involving cell growth, replication and survival of cells in culture. Around 30 50% of cellular folates are located in the mitochondria. Toxicity arising due to water soluble vitamins Toxicities arise due to over supplementation levels or more inclusion rates of the nutrients. Generally the toxicity of the water soluble vitamins is not seen in the birds because of the reason that these vitamins have a very minimal storage in the body. If the inclusion rate of vitamin B-complex is at least 100x than the required level, it tends to cause toxicity in the poultry. Vitamin C, E and Biotin are moderately toxic, potentially causing problems at 20-30x the normal inclusion levels. Toxicity of vitamins administered in the drinking water is quite rare because the birds are reluctant to drink such fortified water (Leeson, S. and J. D. Summers, 2001). Conclusion From above discussion it can be concluded that the water soluble vitamins play many important roles in the poultry life including proper growth, production, weight gain, egg production, immunity, proper conformity, proper functioning, avoiding of stress due to many origins, proper feathering, proper skin condition and proper embryo development. The water soluble vitamins are required in the metabolism, in the oxidation and reduction reactions as coenzymes which mean these are vital for the survival of the animals. These also enhance the quality of the ejaculation in male fowl as well a act as antioxidants for the avian spermatozoa ensuring the fertility and avoiding deformities in the semen of poultry. The water soluble vitamin family member, ascorbic acid is also involved in extra gain of the breast meat which is most liked part of chicken meat in general.
