You can float paper boats or other lightweight objects in the maelstrom.Pour a cup of liquid nitrogen into about a liter of warmed bubble solution to produce a mountain of bubbles.Pour a small amount of liquid nitrogen into a Pringles can and pop the lid on. The vapor will (loudly and forcefully) pop the lid off.Break an incandescent light bulb (type with a filament). Turn it on in the liquid nitrogen. Cool glow!Bounce a lightweight hollow ball on a hard surface. Immerse the ball in liquid nitrogen and try to bounce it. The ball will shatter rather than bounce.Pou r liquid nitrogen onto weeds to kill them. The plant will die with no toxic residue or other harm to the soil. Examine the color change of LEDs under normal temperatures and in liquid nitrogen. The band gap of the LED increases at lower temperature. Cadmium red or cadmium orange- bandgap of Cd(S,Se)- are good choices.Foods high in water will break with a tinkling sound like glass when smashed. Orange segments are a good choice for this project.Insert flexible rubber or plastic tubing into a dewar of liquid nitrogen. The nitrogen will spray out the end of the tubing onto you or the audience, etc. so use care that you have protection on the hand holding the tubing and that there is enough distance at the top of the tubing for the nitrogen to vaporize before contacting with people. Although the tubing is flexible at room temperature, at liquid nitrogen temperature it becomes brittle and will shatter if hit with a hammer or whacked on a lab bench. If you twist the tubing around itself before putting it in the nitrogen, the tubing will uncoil itself as it thaws, in a sort of serpentine manner.

6 Career Risks You Should Definitely Take if You Want to be Successful

6 Career Risks You Should Definitely Take if You Want to be Successful You’ve probably heard stories about people who have found career success by taking crazy leaps of faith. These days, playing it totally safe isn’t necessarily the way to reach the goals you hope to attain. While you certainly shouldn’t be reckless and take wild risks that could end your career (or damage it), there are some risks that are consistently worth taking across the board. But how can you tell the difference between a risk that’s silly and a risk that will pay off? Here are a few examples of risks worth taking, whenever the opportunity knocks.1. Ask for more.Are you growing enough in your current position? Are you being challenged? Are you making what you’re worth? Do you have the training or certification you need to flourish in your job? If the answer to any of these is no, then do your homework, figure out what you would need to succeed, and then propose a plan to your boss about how you can get to where you want to be. Even if you donâ €™t get everything you want, you’ll at least show your boss that you mean business- and that you know your own value. Start networking above your pay grade, and explore opportunities that would require you to stretch.2. Don’t think of salary as the ultimate goal.Keep your work-life balance squarely in your head. Anytime you think you aren’t being compensated enough, think of any non-monetary perks or benefits you receive. Also consider the culture of your company, and any life perks it affords you. If you’re sublimely happy where you are socially, professionally, and personally- and you’re getting enough time to flourish outside your job as well as in- then more money might actually hurt  your life rather than help you to continue at a pace and style you enjoy.3. Do what it takes to learn stuff.Never ever pass up an opportunity to learn something new. Whenever you feel stuck, think about whether you could pick up another skill, certification, or even a degree. It’s never ever a bad idea to gain more knowledge, because along with it comes confidence, expertise, and credentials you can use to enhance your career!4. Take a big move in the direction of your passion.If you’re stagnating at work and you’ve thought of every possible way to make it better, but just can’t, then try something new. Strike out in a different direction. Maybe you can cut back on your hours and add on a part-time job doing something else to dip your toe in new waters. Or you can think about how to start your own side business and go it alone. Only bold moves can get you out of real ruts. Don’t be afraid to make them and move away from the cushy trap of â€Å"what you know.†5. Learn to say â€Å"no.†In this cutthroat economy where companies are downsizing and merging left and right, make sure you aren’t too afraid to say â€Å"no† when you’re getting dumped on. If you’re bein g asked to handle more work than you can do effectively, then it’s really okay to say â€Å"no.† You’re not being lazy; you’re making sure to take care of your professional and mental health and get your work done well.6. Follow your bliss.If you don’t have a passion for what you’re doing, then the bottom line is that you can and should pursue every opportunity that comes up to get you moving in the direction of your bliss. Even baby steps in the direction of happiness are better than no steps at all.

Dances With Wolves Essay Example | Topics and Well Written Essays - 500 words

Dances With Wolves - Essay Example shows a deep understanding and appreciation for the cultures he comes into contact with and goes so far as to adopt their way of life as superior to that of his own previous way of life. When the film opens, Lieutenant Dunbar is faced with the unpleasant choice of either having his wounded leg amputated or choosing to die with it still attached; as did so many other soldiers of his time. However, rather than choosing the amputation, Dunbar decides he will commit suicide by charging the lines of the enemy and dying in a hail of bullets. However, his plan does not go according to planned as his action has the effect of rallying the troops behind him and winning the battle. As a reward for his actions, Dunbar is offered a transfer to any unit or regiment he can choose. Dunbar chooses to move West away from the horrors of the Civil War and into the mystery of the frontier (Costner 1990). His frontier life is far from what he expected as he soon finds himself all alone at an abandoned base; completely cut off from the outside world. It is at this point that the film develops into the story of how Dunbar begins to come into contact with the Native Americans in the surrounding regions to that of the base in which he alone guards. Rather than being hostile to these natives, Dunbar seeks to strike up a relationship with them and engage them in a form of conversation (although his language skills are non-existent). Rather than viewing the Native Americans around the fort as natural born enemies, Dunbar is intrigued by their lifestyle, their curiosity, and the means by which they have sought to survive even in the face of continuous attacks from white frontiersmen. Dunbar becomes so taken by the culture and lifestyle of these Native Americans that he abandons his post and seeks to live a life among them. The story further develops as Dunbar returns to the fort to retrieve a notebook of valuable information he encounters his former colleagues who capture and beat

Water Contamination Assignment Example | Topics and Well Written Essays - 500 words

Water Contamination - Assignment Example Farms do two things to chicken manure: dump it in any available water resource or use it on the fields. Pohlmann decided to 14.1 tons of land-applied manure to one acre. This was done despite the recommendation limiting manure to six tons per acre (Rish). According to the Natural Resources Defense Council, Ohio has no Clean Water Act permits that specify control over livestock operations like Buckeye’s chicken farm. Also, Ohio’s Trade Secrecy act permits factories like the Buckeye farm to dump their manure in an off-site location without revealing the area. However, it is not the manure spill alone that affects the poison content of the water. The intensive confinement of thousands of chickens can result in manure that is far beyond the soil’s absorption rate. The runoff that results from this heavy manure can cause not only water pollution but also affect the land. In the water, it causes eutrophication which makes the soil so rich in organic and mineral content that the amount of oxygen in the water is depleted (HSUS 2005). The difference is that while the plants in the water thrive, the animal life in the water body suffers. This contamination is not a problem for the land and animals alone. The polluted water that drains into the rivers is a percentage of the drinking water for the humans in that area. Grant claims that 60% of the water dumped into these rivers is used as drinking water by the locals of Ohio (1998). Thus, Buckeye farm profited from a number of loopholes in Ohio’s state program. The farm was not forced to reveal the places it dumped the manure preventing the citizens from knowing if the manure is not being properly disposed of in streams or wells. Ohio’s environmental body also has the permission to ask for the management of livestock manure if any farm has more than 1000 livestock units: like the Buckeye Farm.

Research Ethics Stanford Prison Experiment Summary Essay Example for Free

Research Ethics Stanford Prison Experiment Summary Essay The Stanford Prison Experiment (SPE) was conducted in 1971 at Stanford University in the basement of the psychology building. Philip Zimbardo as lead researcher headed the research team to study the impact of situational variables on human behaviour. Zimbardo and his team advertised for volunteers to a social experiment offering $15 in payment per day. Wanting to examine the â€Å"dark side† of human nature, applicants were required to have no criminal record, no psychological issues and no major medical conditions. Each of the 70 applicants were psychologically tested and the 24 most â€Å"normal† were selected to take part in the SPE. The 24 selected participants were then divided into two groups randomly, with one half being prisoners and the other half being guards. The guards were taken to the mock prison before the prisoners arrived to help in the final stages of the prison’s construction and to help select their military style uniforms, this was to give the guards a sense of ownership over the prison environment. Alternatively the prisoners were surprised with real police and authentic processing before being incarcerated into the prison. Despite it being an artificially created environment the guards and prisoners quickly altered their behaviour in response to the situational variables of the experiment. Prisoners were dehumanized and their individuality stripped away, while the guards became increasingly more sadistic and degrading towards the prisoners. After the guards crushed an early attempted rebellion by the prisoners, one prisoner was released for acting irrationally to a point that seemed pathological. After this some of the prisoners became super-conformist, following rules to the letter. While other prisoners began to act crazy in an effort to passively escape like the first released prisoner. The guards fell into three categories with some acting sadistically and degrading towards the prisoners, others going completely by the book and some guards acting kindly and doing small favours for the prisoners. None of guards ever intervened or questioned the actions of other guards however no matter what kind of guard they were. The experiment was terminated early after just six days when an outsider, a recent PhD graduate came in from the outside and saw how out of control the experiment had become. Ethical issues that arose during the SPE were the harm done to the participants. Guards were allowed to inflict real pain and humiliation on the prisoners over an extended period of time. The experiment was allowed to continue for longer than it should have because the participants and observers fell too deeply into their roles. There was also little or no regard for the participants’ confidentiality during the SPE.

The Role of Postmodern Military Coup of 1997 on Transformation of Turk

INTRODUCTION Since the early days of the Turkish Republic, Islamist parties and groups positioned themselves against the values and institutions of the secular republic. Their stance against the secular state also defined their position against the west and modernization. For Islamists, the Kemalist state was in cooperation with the West and all the decisions made by the secular state against religion were inspired by the West. According to them, all the attempts to modernize and westernize the state specifically were aimed at undermining Islamic values. The struggle between state and Islamists, initiated by the reforms to create a modern nation state, such as the abolition of the Caliphate, the abolition of Islamic schools, the abolishment of sharia law, the introduction of Latin script, the removal of state religion from the constitution, deepened after `the transition to multi-party period. This struggle shaped the mindset of Islamist political parties until mid-1990s. During this period of time, Islamic parties defined themselves as â€Å"anti-western† and rejected political culture and values of the West. Therefore, their political discourse always attacked to liberalism, democracy, secularism and the European Union since they were the products of the Western world. However, the liberalization of the Turkey after 1980 in economic and political realms and the developments in global political order transformed the political nature of Turkish Islamist movement and Islamist parties have turned to a liberal and democrat wing in Turkish political life.

Regional Integration for and Against Article-EU Essay

With all complex political and economic ventures there are pros and cons. Regional integration is no different and has many benefits and risks. In order for one to gain a better understanding of the issue, it is necessary to examine both the advantages and disadvantages of regional integration. In this paper I will look at some of the advantages and disadvantages of regional integration in the European Union. I will also discuss the economic stages and growth of France and Austria. The European Union (EU) was created in the late 1950’s to bring about peace, equality, and the value of human rights. It has grown into one of the strongest regional groups in the world and has acquired a total of 27 members. With these values at the helm of the European Union’s work its membership has grown. Many countries flock to join the EU because of its numerous benefits. These benefits validate the formation of regional integration as an effective means to achieve peace, security, and prosperity. There are many economic advantages of regional integration. It can produce bigger markets with more trading opportunities, while boosting competition and reducing prices for consumers. It has also been shown that integration introduces higher levels of domestic and foreign investment. EU has advanced by introducing common currency-Euros. The presence of a common currency is a benefit to consumers because some of the transaction costs are reduced. When members of EU trade there is not a need to buy or sell foreign currencies; therefore the losses of exchange is removed due to regional integration. In this situation firms are able to pass on their savings to consumers by reducing their prices. Trading generates a lot of wealth which helps European Union give its citizens a better life and future. The EU works to achieve fair trade and wants to ensure that its partners in developing countries can join their system. With the formation of the regional organization, firms are able to have greater and easier access to the markets of other members. This increases market size and allows firms to enjoy higher potential profits. Firms also  are able to have greater access to resources from other member’s states. This has been said to lower costs of inputs to allow them to increase their profits as well. Regional integration also allows firms to expand and increase profits and when profits and output increase, this will assist to promote economic growth in the country and the region. With regional integration member states have the support of other member states and this increases investors’ confidence in the region. With more confidence in a region investors are willing and able to invest in EU with confidence. All of these things will help EU to achieve its goal, promote growth and increase standard of living across the entire region. Austria and its economy greatly benefited after entry into the EU in the late 1990’s but with this interdependency Austria has become vulnerable to financial instability. A few of the banks there required assistance from the government such as nationaliz ation. In an effort to strengthen banking groups Austria National Bank came up with a system of measures and moved up implementation of the Basel III rules. They will continue to restructure and encourage greater labor flexibility and increase participation of labor to offset many of its problems. France came up with a series of economic plans that would provide a growing governmental direction of the economy. Some of their plans included an expansion of their basic sectors which exceeded the goals they set. Another plan was to create monetary stability and balance foreign payments. This increased production by 20% and brought forth a major economic expansion. France faced poor growth, lowered public finances, and elevated unemployment before joining the EU. After joining France moved into liberalization. Large shares of utilities and telecommunications were privatized. In spite of the European Union (EU) being most influential regional in the world many countries aren’t interested in joining. This is largely due to the disadvantages of regional integration. One disadvantage to regional integration would be the loss of sovereignty . To establish integration member nations are made to give up their sovereignty to a regional parliament, council, or other body. This body will have authority and make decisions that may affect every member. Regional integration also makes it hard for national governments to issues and carries out policies based on what they need. These policies which may be beneficial to one member could hinder the economies of other member nations. (Alfredo, D.  2011) In regional integration members enjoy lower tariffs for trade but this could result in an unfair comparative advantage over non-member states. This would mean countries are no longer able to trade based on their comparative advantage because of the discriminatory tariffs and barriers that EU practices. When countries are unable to trade according to their comparative advantage, production is less efficient and they will no longer reap the benefits of free trade such as higher world output and lower prices. Even though it has been argued that regional integration allows firms to gain greater access to markets of other member states and thus enjoy higher potential profits. Regional integration also exposes firms to greater competition from firms of other member states as well. Failure to compete with firms may cause local firms to close down. This will increase unemployment rate in the country. (Advantages & Disadvantages.2010) After reading this paper it appears evident that regional integration brings member nations together in times of prosperity and times of difficulty. The advantages and disadvantages discussed in this paper can each be seen as beneficial, harmful, or neutral, depending on what is going on in the world economy and the domestic situation of member nations.

Mondavi Wines Competitive Threats

Mondavi: What threats in the business environment does Mondavi face and how is it addressing them? High quality premium wines produced by France, Italy, Spain, Chile and Argentina. In the past years, Demand increased for premium wines, while consumption of inexpensive, lower quality wine had fallen. As a result of changes in consumption patterns, Europe had created a great deal of excess capacity, while wineries of the new world (South America) continued to increase vineyard acreage in response to strong demand for high quality wines. The size of the global wine industry was estimated by 155 billion dollars (approximately), where Europe and South America dominated global consumption of wine with a market share of 70%. Mondavi addresses this issue by leading the production of premium table wines in the US instead. This market participated with 11% of total world consumption representing 17 billion dollars. Analysts expected demand for premium wines to grow at 8% to 10% per annum. Thus, Mondavi focused 90% of its sales in the US through 15 top retailers and 10% to the rest of the world through exporters. Leverage Risks and Capital requirements The premium wine industry is a capital intensive business. Historically, Tim Mondavi and his team had financed its operations and capital spending principally through borrowings, as well as through internally generated funds. They owned vineyards in California, and the joint ventures controlled land in California, US and Italy, which produced 7% of the company’s total grape supply. The company purchased the rest of its grape supply from 360 independent growers through long term legal agreements. Because in the last years property value had risen and competitors had spent large amounts of money pursuing aggressive acquisition strategies, they could not face further growth with the same strategy due to the increasing high cost of capital. On the other hand, they could not outsource more grape from independent growers, since Mondavi worked closely with the growers to guarantee prime quality and the use of the new farming techniques developed by the company’s own vineyards. So Mondavi chose to focus on a different strategy for the future. He planed to grow its internal grape sourcing by 25% by 2005, focusing on organic growth of the wine and appealing to a new segment of consumers. Management plans to take the company to the next phase by enhancing the high quality of their existing brands, appealing to the organic sectors of healthy consumers and strengthening market positions. Product Substitutes Mondavi faced three types of competitors: rival firms that were focused on making premium wines, large-volume producers moving aggressively into the premium wine business, and global alcoholic beverage companies that were acquiring wineries to complement their beer and/or distilled spirits businesses. He estimated that only 12% of the consumers drank 88% of wines purchased in the US. To stimulate demand for his products, Robert Mondavi set out to educate American consumers and to enhance their appreciation of fine wine. Over the years, he became a leading promoter of the California wine industry. He encouraged visitors to tour the winery and to taste the new wines that he created. In addition, Mondavi began to host concerts, art exhibits, and other cultural events at the To Kalon vineyard. In 1976, the company established the Great Chefs program, the first winery culinary program in the US. Robert Mondavi explained his philosophy regarding fine wine, food, and the arts: â€Å"People who enjoy food, art, music, also enjoy fine wines, and they enjoy them more together. . . . Wine is more than a drink. It’s a culture. † Over time, the company began to advertise more extensively to broaden its customer base. Mondavi launched its first major radio advertising campaign to promote the Woodbridge and Coastal brands in 1998 and its first national television advertising in the fall of 2000. The firm’s advertising expenditures, including point-of-sale materials, reached $20 million in 2001. Michael Mondavi reflected back on the limitations of the firm’s marketing strategy of the early 1990s: â€Å"All those black tie events. We were complacent, cocky, and started believing our own press. For decades, our industry sent the wrong message, that wine is for special occasions, while the breweries told people that beer is the beverage of every occasion. That’s crazy. In the old country (Italy), wine was a blue collar beverage, not an elitist, white collar drink. Our goal is to grow the customer base by removing wine’s mystery, while still maintaining the magic. † As previously mentioned, the next step is becoming organic wine producers of its premier brands. While maintaining high quality standards, he will reach the new target audience of green consumers.

Free Essays on VOIP

(VoIP) INTRODUCTION: In the eyes of most, all packets are created equal. One of the most active areas of telecommunications today is in the area of Voice over Internet Protocol (VoIP). The logic behind this trend makes perfect sense. If we have invested heavily in an Internet Protocol (IP) network, why can't we make full use of it? This is a question posed by many managers and Information Technology (IT) professionals in a wide range of businesses. Many businesses would prefer to have one network in and out of their business for reasons ranging from cost effectiveness to manageability. IP telephony offers a promise of consolidation. This will allow an enterprise to converge its traditional phone system and newer data network for greater efficiency. Arieh Dranger, president of neXTel Systems LLC says, "I don't think it's a question of whether we need VoIP, but when it will come together, because it represents a natural progress of integrating data- period. The IP protocol is probably the most efficient at combining a universal communications network." Basically, IP telephony is taking the telecom world by storm. It has evolved from a little known and used application in 1995 to an application that is poised for global adoption. But as with all technology, there is a price to be paid, and several entities vying for a piece of the pie. WHAT IS VoIP and HOW DOES IT WORK? To put it simply, VoIP means Voice over Internet Protocol. It's a technology that allows network managers to route phone call over the network they use for data transmission. A voice travels over a corporate Intranet or the Internet instead of the public telephone system. Special gateways installed at both the sending and receiving end of a communications channel converts voice to IP packets and back again to voice. This process must take place in a time frame of less than 100 milliseconds to sustain the Quality of Service (QoS) that users are acc...

Free Essays on VOIP INTRODUCTION VOIP means voice over Internet Protocol. A term used in IP telephony to manage the delivery of voice information using the Internet Protocol. It is used to send voice information in digital form in packets rather than using the telephone network. VOIP uses a real-time protocol to help ensure timely and prompt delivery. It also has the potential to change communication and to speed up the delivery of advanced services to all Americans. ADVANTAGES A major advantage of VOIP and Internet telephony is that it avoids the tolls charged by ordinary telephone services. Other advantages include, integration of voice and data, simplification, network efficiency, cost reduction, and many more. The comparison between data and voice network is very similar and the Internet is a huge part for both. The industry trends work over telephone services also. However, the benefits of using IP as a generic platform for both data and real-time application are compelling enough to resolve all issues. MAJOR SYSTEMS A major system component would be the gateways. They are devices that control the communication between the telephone signals and the IP endpoints. It is also an information services that delivers voice communications and joins voice coverage with other data applications and devices. The gateways perform six functions, search function, connection function, digitizing function, demodulation functions, compression function, and decompression and remodulation functions. When the gateway is still performing steps it also receives packets that is where gatekeepers take place. The gatekeeper performs address translation, admissions control, bandwidth management and zone management. An IP telephone is another system component. These devices replace the old telephones by providing enhanced services that are best used for VOIP. QUALITY The voice quality is very important to VOIP technology. There are certain factors tha...

Habits and Traits of Owlet Moths

Habits and Traits of Owlet Moths The owlet moths (family Noctuidae) account for over 25% of all butterflies and moths. As you might expect in a family this large, theres a good deal of diversity within this group. Though there are exceptions, most noctuids share a common set of traits outlined here. The family name, Noctuidae, derives from the Latin noctua meaning little owl or night owl (which in turn derives from nox, meaning night). What Do Owlet Moths Look Like? As youve undoubtedly already deduced from the family name, owlet moths tend to be nocturnal. If youve ever tried black lighting for insects, you must have collected some noctuids, because most will readily come to lights. The owlet moths are robust, stout-bodied insects, usually with filiform antennae. The fore wings tend to be mottled in color, often cryptic, and slightly longer and more narrowed than the hind wings. In most, the hind wings will be brightly colored but kept hidden under the forewings when at rest. Some owlet moths have tufts on the dorsal surface of the thorax (in other words, theyre furry!). For those readers who enjoy confirming their IDs by studying wing venation details, you should note the following traits in the owlet moths you collect: The subcosta (Sc) arises near the base of the hind wing.The subcosta (Sc) fuses briefly with the radius near the discal cell in the hindwingThree medio-cubital veins extend to the distal edge of the hind wing As David L. Wagner notes in Caterpillars of Eastern North America, there are no unique identifying traits of caterpillars in this family. In general, noctuid larvae are dull in color, with smooth cuticles and five pairs of prolegs. Owlet moth caterpillars go by varied common names, including loopers, earworms, armyworms, and cutworms. Owlet moths sometimes go by other common names, such as underwing moths or cutworm moths. The family is divided into several subfamilies, although there is some disagreement about their classification, and some sources may consider these groups separate families entirely. I generally follow the classification system found in the latest edition of Borror and Delongs Introduction to the Study of Insects. How Are Owlet Moths Classified? Kingdom – AnimaliaPhylum – ArthropodaClass – InsectaOrder – LepidopteraFamily - Noctuidae What Do Owlet Moths Eat? Noctuid caterpillars vary greatly in their diets, depending on the species. Some feed on foliage, living or fallen, some on detritus or decaying organic matter, and still others feed on fungus or lichens. Some noctuids are leaf miners, and others stem borers. The family Noctuidae includes some significant pests of agricultural crops and turfgrass. Adult owlet moths usually feed on nectar or honeydew. Some are capable of piercing fruit, thanks to a sturdy, sharp proboscis. One very unusual noctuid moth (Calyptra eustrigata feeds on the blood of mammals. You only need to worry about these blood-sucking moths if you live in Sri Lanka or Malaysia, fortunately. The Owlet Moth Life Cycle Noctuid moths undergo a complete metamorphosis, just like any other butterflies or moths. Most owlet moth caterpillars pupate in the soil or leaf litter. Special Adaptations and Behaviors of Owlet Moths The nocturnal noctuids can detect and avoid hungry bats, thanks to a pair of tympanal organs located at the base of the metathorax. These auditory organs can detect frequencies from 3-100 kHz, enabling them to hear a pursuing bats sonar and take evasive action. Where Do Owlet Moths Live? Globally, the noctuids number well over 35,000 species, with the worldwide distribution you would expect within such a large group. In North America alone, there are approximately 3,000 known species of owlet moths. Sources Borror and DeLongs Introduction to the Study of Insects, 7th Edition, by Charles A.

Case Study Example The consultant’s main role is to analyze the factors that can impact the business activities of the company and recommend an appropriate strategy that will be aligned with the corporation’s primary objectives. The UK apparel and textile industry is undergoing drastic changes to provide favorable conditions to the players of the sector (â€Å"Textile Industry†, 2010). In UK, the textile industry is among the major contributors in its economic growth and it employs more than 340,000 people (Macbeth & Miln, 2012). It has been reported by Rogers (2012) that Gross Value Added (GVA) of UK textile sector is about 11.5 billion pounds and clothing manufacture, textile manufacture, dry-cleaning and footwear services are worth one billion pound within the sector (Begum, 2012). As the barriers for trade have been reduced along with decline in transportation cost, the manufacturing plants are shifted to lower cost areas such as China and India (â€Å"Textile and Apparel Compendium†, 2012). In the UK textile sector, there has been a sharp decline in the domestic manufacturing of goods as majority of the textile companies have moved to offshore destinations. Despite the relocation of these plants, the sales and design capacity of the sector has remained constant (Rogers, 2012). The foremost reasons for the surging demand of UK based textiles is that the apparel is manufactured with strong emphasis on high value products that allow the customers to get their goods designed in a customized way (Norris, 2012). As a result of the Industrial Revolution in the global textile industry, the Techtextil has become the latest norm in the textile sector. It encompasses a wide variety of taxonomy that is utilized by all the players operating within the industry (Goworek, 2010). In order to address the key challenge faced by the company, it has become imperative to analyze the alternatives that can be
