Fuel Cell Technology :: Exploratory Essays Research Papers

Fuel Cell Technology Fuel Cells are a hot topic these days between the soon to come fuel cell cars that Toyota and Honda plan on unveiling this year and the $1.2 billion president Bush announced he would dedicate to fuel cell research during his State of the Union address. The least efficient of these electrochemical energy converters are at least as efficient as internal combustion engines and many are doubly as efficient when using special techniques. Exhaust from fuel cells is extremely clean, often consisting only of water. Although some use hydrocarbons, fuel cells give off around one one-hundredth of the pollutants given off by an internal combustion engine using the same amount of fuel (Fuel Cell Technology Handbook). Unfortunately some engineering and infrastructure problems, especially costs, are keeping fuel cells from commercial viability right now. A Brief History of Fuel Cell Technology The ideas behind fuel cells have existed for around one hundred and sixty years. Sir William Grove is cited as the first person to think that one could produce a current by reversing the electrolysis of water (SAE.org). However, it was until fifty years later that the term ‘fuel cell’ was coined by two researchers, Charles Langer and Ludwig Mond, trying to invent the first viable fuel cell fueled by coal gas (SAE.org). The technology lay dormant for most of the early twentieth century because of great advances in the use of internal combustion engines. It wasn’t until 1959 that practical fuel cells were first demonstrated. NASA quickly took interest in the technology for the Apollo missions and since there has been a renaissance in research and development of fuel cells. Currently, there are on the order of hundreds of fuel cell generators in operation world wide, cities such as L.A., Chicago, and New York, own fuel cell powered public transit vehicles, and both Honda and Toyota plan on making fuel cell powered car commercially available within one year (fuelcells.org). How a Fuel Cell Works A fuel cell is an energy converter that uses electrochemical energy to create an electric current. Because they use electrochemistry for power, fuel cells are often likened to batteries that run on fuel. This description is not a bad one, but to be more precise, a fuel cell creates direct current by ionizing a fuel and then moving those ions through a circuit. The three main components are the anode (negatively charged piece), cathode (positively charge piece), and electrolyte (medium for the transfer of ions). Fuel, typically hydrogen, is ionized at the anode by a catalyst (substance that can change an interaction, but does not change the chemistry of it).

The Joys of Skydiving Essay -- Personal Narrative, essay about myself

It was a warm and sunny Saturday morning when my friend, Sivi, and I left our home to travel to the small local airport located outside of town. Just the previous night we had received 4 hours of classroom training in how to perform a successful "Skydive" and now we would receive 4 more hours of practical, hands-on training. Sivi and I have spent a lot of time talking with, and taking care of Senior Citizens on a volunteer basis. Through many conversations, we discovered that one of the major regrets that people have, as the near the end, is that they didn't experience everything that they wanted to when they were younger. The major reason for this was fear. Fear that they would fail or fear that they might be injured. Sivi and I had decided years ago that we would never allow fear to prevent us from trying something new. Now, in our middle and late forties, we had decided to voluntarily jump out of a perfectly good airplane just for the experience of doing so. When we arrived at the airport, there were about 10 other people. Most of them were men and we were the only couple. Of course the first matter of business was to read and sign a waiver that stated that we would NOT hold the skydiving school liable if our jump turned out to be, shall we say, less than perfect. I must admit that this certainly brought out some of the apprehension that Sivi and I had managed to bury deep inside ourselves. Next, we were sent to a shed where there were several sets of coveralls. Here we were instructed to pick out a pair of coveralls and a helmet that fit (as best as possible) and put them on. I must say that I felt more than a little silly wearing a pair of torn and uncomfortably tight coveralls ... ...ove the ground, I yanked down on the parachute control straps with all of my strength. The parachute got more air, and I slowed, almost to a standstill, and gently touched the ground. As my feet touched the Earth, I went into my roll and then stood back up. No broken bones or bruises. Sivi, immediately came out to greet me, and we both felt a great sense of relief and pride. Once again we managed to overcome our fears and experience something that cannot be imagined or viewed like a movie, but must be felt. As we walked to our car, we realized just how much the day had taken out of us physically. We were both bruised and sore from our practice jumps into the gravel pit and very tired. But, at the same time, our souls felt warm and satisfied at discovering that we could overcome our fears and experience the joy and freedom of skydiving.

The LEGO History

Today we will be talking about how the Lego company has started out and how it has gotten this far. Back in 1891 I don't think anyone would have thought it would be what it is today. We will be going back to the day that it started and getting in depth about what happened and how the group has grown to be this big today and what the machines are that the legos go threw. We will be getting into the history that most people don't know and uncovering it. The prices of original legos will be shown, the average cost of each lego produced and how much money they make off an average set of legos. The Lego Company begin in the workshop of Ole Kirk Christiansen in 1891, the group had a carpenter from Billund, Denmark. Who began making wood toys in 1932. In 1934, his company had made their name Lego. In 1947 the Lego group downed their making in wood toys and started to manufacture Legos. Which today is a major company with a net worth of 5.9 billion dollars. The name Lego is a mixture of two Danish words leg and godt, which meant play well. It is their name and ideal. In the past 80 years the company has moved from a small workshop to a massive company producing tons of Legos each day the exact number each day is 36,000 each minute. The average cost of one lego is 10.4 cents. Most of the smaller sets of lego buildings cost around 8 dollars and the more difficult ones are anywhere between 40 dollars and 70 dollars. The lego company started using plastic after many fires happen from the wood and plastic came available after World War Two, so the group decided to try it out and got a plastic molding injection machine. One of the first toys made with the plastic was a truck that could be taken apart and put back together and the company hit it big on that one. The plastic products weren't taken serious like the metal or wood ones because the customers where so use to metal and wood that they were scared to try something new but Lego advertised and advertised and their toys where mainly directed toward pre-school kids. they never really hit it big in the beginning, it took time and persistence to get their toys made right. They officially got rid of the wooden blocks after one of their last plants burned down. The lego group had such a great outcome at the end if 19th century and still do because they have such a high quality product compared to all the other manufacturing company's for toys. The group started to grow because they made the product safer for the kids, the group made the plastic with non-toxic plastic. The group Lego made it non-toxic because Lego wanted his product to be safe for the little kids handling his toys. In the beginning he started out with around four hundred and fifty workers and it grew over time as Lego grew. Now days the Lego group has around approximately fourteen thousand workers world wide. I have watched many videos of Lego reviews and every single one I have ever watched I have never seen a negative review

Detroit Riots

DetroitApril Woodson 4 February 2013 Newspaper analysis Tara Saunders Race riot in Detroit (June 20, 1943) The Detroit Riots, an article from The Chicago daily tribune was published three days after the riots. It talks more about the aftermath of the riots, after troops were ordered in and how it portrays the United States to the international community. The tone the article takes on is almost shameful and gives the vibe that not only should Detroit be embarrassed by the United States as a whole because the riots did spark racial tension in other cities like Los Angelas as well.Though the article is short the intensions of the message are very clear as it reads, â€Å"†¦the race riots which had brought deep disgrace upon that community came to an abrupt end†¦an important lesson to be drawn by the American people from this ugly incident†¦relations between the races in America have improved but we still have far to go before the problem can be regarded as solved. The ad vocates of super governments are asking us to believe that what we have not yet succeeded in accomplishing in America can be achieved with the stroke of a pen on an international treaty† (pg 1).Though the article is on the front page of this particular tribune issue, the location of the article in the newspaper gives one the impression that the riots are now a thing of the past. We know this because the article was published three days after the event and its proceeded by an article about control of rabies. The second article titled â€Å"F. D. R. for Troops in Detroit† which was also published by the Chicago tribune was written two days after the riots and it seems as though its attacking Roosevelt’s decisions to call upon the militia to help stop the riots or explain the reasoning being doing so.He does give the crowd a chance to disperse before he sends out the troops, â€Å"Now, therefore, I, Franklin D. Roosevelt, President of the United States, do hereby c ommand all persons engaged in said unlawful and insurrectionary proceedings to disperse and retire peaceably to their respective abodes immediately and here after abandon said combinations and submit themselves to the laws and constituted authorities†¦Ã¢â‚¬  (pg 2). I think this is important to note because a lot of people think it was just an attack on innocent people.This article also seems like it was published at the height of the riots when everything was in complete and utter chaos. The author of this article isn’t necessarily analyzing the riots but rather the political reasoning behind how appropriate Militant intervention would be. This article is also brief but it is important as it covers a big milestone during the riots and ultimately one of the biggest courses of actions, which was the decision of F. D. R. to send in troops to Detroit.This shows just how bad the riots were at that point and in relation to the last article I think this article unknowingly gi ves the readers an insight into just how embarrassing the aforementioned â€Å"ugly incident† really is. The third article from the Chicago daily tribune was also published two days after the riots. However this article takes up the whole front page with the title Army Rules Detroit it gives the impression that these were the last big moment of the riots, like the city was a damsel in distress and the Army was the superhero that came to rescue it.The article almost points to sum up the riots in the title by making three things obvious under the Army Rules Detroit we see in little letter, 23 die: Homes fired, shops looted in race riots, 700 wounded in wild disorders. Unlike previous articles its obvious this one was probably written by a racist author. The author of this article refers to black people as â€Å"Negro’s† and â€Å"negresses†. His tone makes it seem like African Americans are animals that cannot be tamed and the only option was military inter vention it also attempts to walk the reader through the state of the Detroit during the riot.Throughout the article we see subtitles like Thirteen Schools Closed, Trolley lines Suspend and Ammunition seized all theses titles seem to explain how out of control the city was, it gives us the bad side of the situation gives one the impression that things don’t seem to look up until the army arrives. Its not coincidence that this is such an in-depth analysis seeing how Chicago is right next door to Detroit. However although its obvious that the riots are the result of racial tension whenever the author quotes a white person he makes them seem like a victim while it may true in some cases he never sheds the same light n African Americans. Newspaper articles from the New York times aren’t as harsh and tend to concentrate more on what caused the riots, what law officials are doing to keep if from happening again as well how they are trying to punish the people who played major roles in the riot. Even democratic Representative John E. Rankin of Mississippi is quoted saying, â€Å" Detroit has suffered one of the most disastrous race riots in history† (pg 1). It says a lot when politician in the south could say such a thing when a lot of racism during that time is rooted in southern states.The New York Times focuses a lot on the aftermath of the riots and provides coverage on how the presence of the Army helped. One article from the Chicago tribune is titled in bold letters Army Rules Detroit and when one tries to tie the agenda of the two newspapers together it seems as if the New York tribune picks up where the Chicago tribune leaves off. The Army arrives and then we get to see what the Army does and the control measures implemented to keep such riots from happening again. These articles in general are trying to put the public at ease, to reassure them that once again Detroit is under control.From the Washington post we see feelings of shame and e mbarrassment resurface again. One-article titled Detroit Tragedy begins with, â€Å"No American can escape a feeling of shame as well as sorrow over the race riots†¦such an outbreak is at its ugliest when it stems from race hostility. † Just like the New York times, the Washington post also suggest that the main cause of the riots was â€Å"the inadequate living facilities of a community which has become desperately overcrowded as a result of the war. (pg 3) When reading through this article words like, ugly, disgrace, dangerous, shame and enemy really stick out, these are the words that best describe the riots and the impact it had on the people. Throughout newspapers across the united states the riots where regarded as ugly and I think the aforementioned quote â€Å"Such an outbreak is at its ugliest when it stems from race hostility†, best sums of the how the country viewed the riots.Though the riots only lasted twenty-four hours, during those hours the whole country was watching domestically and especially internationally with World War II also taking place.

Characteristics of a Human Service Professional Essay

Individuals working in hospice are a great example of chronic bereavement. â€Å"Chronic Bereavement refers to multiple losses and include the effects of chronic anticipatory, and unresolved grief, as well as the compounding effects of experiencing several episodes of grief concurrently† (Hooyman p 349). While meeting the emotional needs of the dying and their families health services professionals don’t have always have time to deal with their own grief appropriately. Compassion Fatigue â€Å"Compassion fatigue describes the convergence of secondary traumatic stress and cumulative stress or burnout, which is most prevalent among professionals, family members, and associates of trauma survivors (Hooyman p350). Many human service workers have had some kind of early-life trauma that influenced their career choice which makes them more vulnerable to compassion fatigue. The symptoms of compassion fatigue are similar to those of primary traumatic stress disorder. They differ in that compassion fatigue doesn’t affect the health care provider. Vicarious Traumatization Vicarious traumatization (VT) is defined as â€Å"the negative transformation in a helper’s inner experience that takes place as a result of deep empathic engagement with traumatized clients couples with a sense of professional responsibility to help.† (Hooyman p350). There are many considerations when treating vicarious traumatization, especially during self-care such as awareness, balance, and connection. Awareness is to recognize signs and symptoms of vicarious traumatization, avoid substances that numb your feelings and awareness and listen to those who have noticed changes in you and discuss those changes. Balance is setting limits to availability to therapeutic work and setting realistic expectations. Then you need to know to apply what you have learned in the workplace and your personal life. Burnout Burnout is one of the main reasons for the quick turnaround in the health care profession. â€Å"Burnout refers to physical, emotional, and psychological exhaustion accompanied by a sense of demoralization and diminishing caring and creativity and personal accomplishments†. (Hooyman p352) To avoid burnout to quickly, health professionals may need to take long weekends or vacations to rejuvenate themselves. Countertransference â€Å"Countertransference is broadly defined as the personal reactions elicited in the professional relationship, directed toward the client and stemming from the professional’s previous experiences.† (Hooyman p 355) Countertransference occurs when a health care provider has unresolved issues and those issues affect the patient. Countertransference reactions include but are not limited to: being overprotective, rejecting a client, needing constant approval or reinforcement. Self-awareness is necessary to avoid countertransference.

Business: Luxury Good and Competitive Advantage Essay

5. What is Coach’s strategy to compete in the ladies handbag and leather accessories industry? Has the company’s competitive strategy yielded a sustainable competitive advantage? If so, has that advantage translated into superior financial and market performance? A business strategy refers to the means by which it sets out to achieve its desired objectives and goals. Coach’s competitive strategy deals exclusively with management’s game plan for competing successfully and securing a competitive advantage over rivals Michael Kors, Salvatore Ferragamo, Prada, Giorgio Armani, Dolce & Gabbana, and Versace. The different types of strategies used by these companies include, but are not limited to, low-cost provider strategies, differentiation strategies, focused low-cost and differentiation strategies, and best-cost provider strategies. Coach Inc. ’s strategy that created the accessible luxury market in ladies handbags made it among the best-known luxury brands in North America and Asia and had allowed its sales to grow at an annual rate of 20 percent between 2000 and 2011, reaching $4. 2 billion. The company’s strategy focuses on five key initiatives. First, Coach built a market share in North America by 15 new full- price retail stores and 25 factory outlets. They have built a market share in Japan through the addition of 15 new locations. Coach seeks to raise brand awareness and build share in underpenetrated markets, including Europe and South America, and Asia, with 30 new locations planned in the region. It also looks to increase sales of products targeted towards men by offering dual gender lines. Lastly, Coach raised brand awareness and built market share through coach. com, global e-commerce sites, and social networking initiatives. Coach Inc. implements various advertising strategies, marketing strategies, sourcing strategies, and differentiation strategies, etc. Coach’s strategy, which focused on matching key luxury rivals in quality and styling while beating them on price by 50 percent or more, yielded a competitive advantage in attracting middle-income consumers desiring the taste of luxury, but also affluent and wealthy consumers with the means to spend more money. Another distinctive element was its multichannel distribution model, which included indirect wholesale sales to third-party retailers but focused primarily on direct-to-consumer sales. Coach appears to be using the best-cost provider strategy because it gives customers more value for their money while satisfying buyer expectations on key quality features, performance and service attributes. For example Coach uses attractive pricing to enable it to appeal to consumers who would not normally consider luxury brands, while the quality and styling of its products were sufficient to satisfy luxury consumers. Coach has the ability to do this through its factory outlet stores and its prices are way below the price of its competitors. Coach also displays differentiation by offering distinctive, easily recognizable luxury products that are extremely well made and provide excellent value. Coach has a unique approach to its differentiation. Each quarter, major consumer research is undertaken to define product trends, selection, and consumer desires. Monthly product launches enhance the company’s voguish image and give consumers reason to make purchases. They also use frequent product introductions because consumers always want the newest items and fashions. Coach sought to make consumer service experience an additional differentiating factor. It has agreed to refurbish or replace damaged handbags, regardless of the age of the bag. Through the company’s Special Request, customers were allowed to order merchandise for home delivery. Overall Coach displays a great mix of low cost and differentiation. A sustainable competitive advantage refers to a long-term competitive advantage that is not easily duplicable or surpassable by the competitors. Coach’s competitive advantage has proven to yield a sustainable competitive advantage. When it comes to anticipating fashion trends, Coach has 1 / 3 proven to be successful. Each year Coach interviews its customers through Internet questionnaires, phone surveys, and face-to-face encounters with shoppers at its stores. Such intense market research has helped Coach executives spot trends well before its competitors. This in turn has helped it to extend the brand far beyond the leather bags that long were its trademark and into watches, accessories, cosmetic cases, key fobs, belts, electronic accessories, gloves, hats, scarves, business cases, luggage, eyewear, fragrance, and clothing. According to the case study and further research, sales have grown an average of 29% over each of the past three years, fueling a strong 63% averaged return on invested capital during the same period. Currently Coach is a leading American marketer of fine accessories and gifts for women and men. Its sustainable competitive advantage is a result of employee engagement, supply chain capabilities, environmental conservation, and community. Coach seeks to hire and train the best employees in a supportive and engaging environment. Coach collaborates with their raw material suppliers and manufacturing partners. Coach continues to improve the way it makes it products in order to protect the resources of the environment. Coach also supports the local communities in which they operate. Results show that Coach has increased its net sales from $3,230,468 to $4,158,507, its market share increased by nearly 6%, and its common stock price is $60, which is a result of superior financial and market performance. 6. What are the strengths and weaknesses of Coach Inc.? What competencies and capabilities does it have that its chief rivals don’t have? What new market opportunities does Coach have? What threats do you see to the company’s future well being? Coach has many strengths and weaknesses. Coach strengths include its wide range of accessories such as its handbags, watches, accessories, cosmetic cases, key fobs, belts, electronic accessories, gloves, hats, scarves, business cases, luggage, eyewear, fragrance, and clothing. It is the leading luxury leather goods company in the United States, with expansion in Japan, China, and Asia. Coach has developed a respected reputation by providing their customers with quality products and its 70+ years of being in business. They do a great job of advertising through press releases, catalogs, internet, and shopping centers. Coach has a larger range of pricing which attracts lower income consumers and wealthier consumers. They also allow their products to be sold at stores (department and full price stores) and online. Coach prides themselves on creating customer value. However, Coach also displays weaknesses as well. They have a limited selection for men and a poor inventory turnover rate. Coach has no direct announcements to the public about the promotion of new products. Their new products first sell at full price which keeps the lower income consumers away. This could lead to the problem of selling more at their outlet stores versus their full price stores. Currently Coach relies on the United States, Japan, and Canada for the majority of its sales by not fully expanding into other countries. A core competency refers to a defining capability or advantage that distinguishes an enterprise from its competitors. Coach believes that external coaching and leadership workshops are powerful tools in increasing a leader’s awareness and insight on their management approach, which leads to core competencies and capabilities. Coach has the skill and expertise to create unique and differentiated luxury items at a lower cost than its competitors. It also has valuable physical assets, human assets, organizational assets, intangible assets, and alliances and cooperative ventures. All of these resources and capabilities are valuable, rare, hard to copy, and non-substitutable. Some of the defining characteristics that distinguish Coach from its competitors include its wide selection of luxury items, its low cost strategy, store location (outlet and full price), advertising, online shopping, meeting customer desires, superior value and quality, its direct-to-consumer channels and indirect channels, 970 wholesale locations in the United States and Canada, specialty retailers in 18 countries, and its relationships with consumers (customer loyalty). Coach’s strategy, which focused on matching key luxury rivals in quality and styling while beating them on price by 50 percent or more, yielded a competitive advantage in attracting middle-income consumers desiring the taste of luxury, but also affluent and wealthy consumers with the means to spend more money. Another 2 / 3 distinctive element was its multichannel distribution model, which included indirect wholesale sales to third-party retailers but focused primarily on direct-to-consumer sales. Coach has many new opportunities in its market of luxury goods. It has a high potential for increased sales with new product lines. The promotion in other countries can bring awareness to the brand and company. Its pricing can attract more customers because of the lower priced items compared to its competitors. Its online option of purchasing will increase as technology increases. Coach also has the opportunity to increase the number of stores in North America, expand stores in other countries, and use its flexible dependency on suppliers. However, Coach also faces numerous threats. There is always the threat of rivalry, competition, and substitutes in the luxury market. One of the major threats is counterfeit products and the economic downturn in the United States. Young adults and teens often go through phases of fashion and may later chose a different brand other than Coach. Coach faces exchange rate risks if they enter new foreign markets. Lastly there is a threat of not having enough stores around the world which could hurt the consumer market. These threats could hurt the well-being of the company, but its strengths and opportunities seem to outweigh them for the time being.

Is there microbial life in Mars Research Paper Example | Topics and Well Written Essays - 1000 words

Is there microbial life in Mars - Research Paper Example Most recently, scientists have come up with new and improved evidence to support their claims of life on Mars. The experiments, discoveries and propositions put forward by the scientists over the period of time regarding life on Mars are discussed further in the paper. The signs of microbial life first came into picture when the experiments of the Labeled Release (LR) apparatus turned out to be positive. This experiment tested on a sample of Martian soil by mixing it with a drop of water constituting of nutrients and radioactive carbon atoms. If the soil was positive for microbial life, the nutrients in the soil would be metabolized and radioactive gases such as methane or carbon dioxide would be produced. Control samples were also prepared by heating or isolating the samples that would kill any form of life if it existed. Control samples were also mixed with nutrient solutions; hence the control experiments provided a comparison. To the amusement and the excitement of the scientists , the LR experiment turned out positive for life. â€Å"The minute the nutrients were mixed with the soil sample, you got something like 10,000 counts of radioactive molecules- a huge spike from the 50 or 60 counts that constituted the natural background radiation on Mars† (Than). These were the earliest experiments performed by the NASA scientists in pursuit of their discovery for life on Mars. Although the LR experiments turned out positive but other space probes’ experiments were negative, making the existence of microbial life on Mars skeptical. Recently, the gas emissions on Mars have been linked to biological source. The experts believe that the chances for organisms to be a source of the gasses are quite explanatory and supportive of microbial life on Mars. The methane gas produced on the Red Planet is suspected to be produced by certain microbiological organisms. On the other hand, some scientists believe that methane can be a result of geological reasons i.e. volcanic processes. However, no active volcanoes have been discovered up till now on Mars. This evidence and explanation strengthens the probability of microbial life on Earth. Scientists have explained that methanogens, certain organisms, release methane as a waste product which dwells in the water beneath the underground ice. According to Prof Pillinger, â€Å"The most obvious source of methane is organisms. So if you find methane in an atmosphere, you can suspect there is life† (Staff Reporters). Miller and mathematician Giorgio Bianciardi, employed a cluster analysis technique on the Viking’s data. This technique groups together similar looking data. This analysis was performed to evaluate the realism of the experiments and investigate the outcome of the experiments. The technique turned out with two clusters; one with two active experiments and the other with five control experiments. The biological experiments from Earth sorted with the active experiments from Vi king exhibiting the validity of claims of microbial life on Mars. Another finding which supports the previous LR experiments is the Martian Rhythms. Circadian rhythms are internal clocks which can be found in every living thing, including microbes. On Earth the clock is set to 24 hour while on Mars it should be 24.7 hours, which is the duration of a Martian day. Miller noticed that the radioactive gas measurement sin the LR experiments exhibited a rhythmic rise during the day and decline during the night. The oscillations were in accordance with the Martian
