Many Types of Drop-In Fuels

Many Types of Drop-In Fuels These days, it’s hard to find an organic material that isn’t being positioned as the next great alternative energy source. Rising to the top of the list are biofuels known as so-called â€Å"drop in† fuels – those renewable sources that can be used without major investment in infrastructure in the U.S. where storage and distribution has long catered to petroleum. That current investment in infrastructure isn’t small potatoes. There is about $7 billion in pipeline expenditures alone each and every year. Defining Drop-in Fuels What defines a drop-in fuel? The alternative fuels industry itself isn’t exactly clear, with some defining it broadly to mean any renewable fuel making use of at least some of the costly existing petroleum infrastructure. Others have taken a more narrowed approach. One of the most popular definitions is that drop-in fuels are those renewable fuels which can be blended with petroleum products, such as gasoline, and utilized in the current infrastructure of pumps, pipelines and other existing equipment.    Under such a definition, a biofuel would require some percentage of gasoline blender , derived from unique gasoline stocks, to form the fuel’s base. Examples of drop-in fuels defined in this way include the terpenes, butanol and isoprene, among other. Often, the technology is applied to diesel fuel, forming a biodiesel, rather than to gasoline. There are even some next-generation biofuels proponents who are developing mixtures of chemicals to form a biofuel without the gasoline or diesel base. Algae Most Common Drop-in Fuel With well over 50 companies investing in the development of algae as a biofuel, the little green plant reigns supreme among drop-in fuels. Yet, despite this general interest, most biofuels experts agree that at least another decade of research and technological breakthroughs will be necessary before this drop-in fuel is deemed commercially viable. That’s a long- and costly- trail ahead. As with most drop-in fuels, the challenges come in moving the technology from the lab to full-scale commercial production. An additional challenge with algae specifically has been the wide variance among algae and the extensive processing necessary. Butanol Also Sees Growth But algae isn’t the only show in town. Last year, a leading biobutanol company, Gevo, announced plans to acquire ethanol facilities in the Midwest and convert them to commercial production of the drop-in fuel isobutanol, also known as isobutyl alcohol.    The move was seen by industry players as a step forward in the development of butanol as an alternative drop-in fuel, with the company hoping to begin isobutanol production by 2012. Although able to make use of existing infrastructure, unlike algae, there is some concern over potential safety threats. Vapors can travel long distances and collect in low-lying areas to form an explosion hazard. However, its proponents are quick to point out the biofuel’s many fuel and chemical applications make it an attractive venture. Big player DuPont has also tested the waters of biobutanol as a drop-in fuel and plans to likewise rely on existing under-utilized ethanol capacity and conventional feedstocks as it gets its operations off the ground. The investment to retrofit existing ethanol facilities is more economical than building new structures and require only minor changes to the fermentation and distillation processes. Broadening Portfolios DuPont says it plans to follow a multi-step approach to drop-in fuel development, first focusing on n-butyl alcohol and conventional feedstocks before moving on to other drop-in fuels like isobutanol as well as non-feed crops, such as cellulosic feedstocks.    Yet another company, ButylFuel, LLC, has gone on record as having said it has now developed fermentation-derived biobutanol at a cost that is competitive with petroleum products. Its drop-in fuel can be blended at a variety of percentages with gasoline or diesel fuels. How competitive? The company claims it can produce its drop-in fuel from corn for about $1.20 per gallon. Like algae players who are benefiting not only from algae as a drop-in fuel, but from the many byproducts as well, research and development in other drop-in fuels sectors are looking at diverse portfolios of products, causing some to characterize this next generation of alternative fuels as a means to produce hydrocarbon blend stock that can have a multitude of applications.

The Immigration and Refugee Protection Act 2002 Essay

The Immigration and Refugee Protection Act 2002 - Essay Example The act replaced the Immigration Act of 1976 based on the need to eliminate discrimination and include refugees in the provisions of the act. The great depression, the ageing Canadian population, low levels of immigrants and economic benefits of immigrants are among the key reasons leading to the development of the act (Arakelian, 2008, pp.67-68). The transformation of the act to the new immigration and refugee protection act stems from the need to stamp out discrimination, encourage population growth and the need for skilled workers. The act has contributed immensely to economic development of Canada as well as promoting population growth and its use should be continuously supported (Beach, Green, & Reitz, 2003, p.167). This paper is going to look at the historical background of the act in terms of its development and values and ideologies that guide the legislation. It will provide statistics and global trends contributing to the act as well as other researches that have been done and which support and are in contrary of the act.it will then conduct a critical analysis of the legislation in terms of how well it serves the population, its strengths and any gaps that exist in service before finishing off with a conclusion that will provide a summary of what was discussed. Historical Background The first immigration act was passed in 1869 and this marked the foundation of Canada’s immigration policy. ... Immediately after the war, the nation experienced a number of setbacks and once again revised the act to a more exclusionary immigration policy aimed at encouraging harmony and control; although certain religions as well as ethnicities were barred from immigrating to Canada. This was followed by a further amendment in 1919 of section 38 prohibiting entry of certain races and nationalities (Westhues, 2006, p.20). After the Second World War, there was a change in attitudes as well as unprecedented economic growth. The senate in 1951 recommended the return of the open door policy stance on immigration which led to a new act in 1952 that did not include much of the proposed changes and continued to discriminate against races and people on economic grounds. A more inclusive policy was arrived at in 1967 that eliminated racial discrimination. 1969 saw the inclusion of refugees into the policy widening increasing chances of people who could immigrate to Canada. Amendments continued until 20 02 when the immigration and refugee protection act was established (Kelley & Trebilcock, 2010, p.11-13). Westhues (2006, p.23) argues that the rationale and ideologies at this time was to attract an influx of immigrants in order to boost the economic growth of the nation. Coming up with the immigration policy was seen as a way of increasing the country’s demand for domestic products and stimulate the nation’s manufacturing sector. At this time also, there were large tracts of land that were unoccupied and thus the need to fill this land with people. The idea of filling up the unoccupied land was as a result of the need to ensure sovereignty of the nation which was an important factor at this time. Therefore it is only through a

Minority Leadership in the military Research Paper

Minority Leadership in the military - Research Paper Example Minorities are often subjected to stereotypes and they are usually not expected to acquire higher positions. They are always looked upon with suspicious eyes and their ability is almost always questioned. In the same way females are also looked down upon in professions like military. In this paper we will look into the minority representation in army and whether it represents the minority representation in the society at large. The educational and financial background of minorities will also be considered and their impact on leadership style will be analyzed. The main question we would like to answer here is whether race or gender has an impact on leadership or management decisions in military or not. It is important to understand the dynamics of minorities in a society in order to better understand how minorities feel and how the society feels about them. Minorities in a society are characterized by cohesion and close relationships. This is because they feel threatened by other majority groups in the society. Minority groups also try to differentiate themselves from ‘others’ and this is done to protect their identity. There are united because they have no place to go and they feel compelled to remain a part of their social group. Society in general feels negatively about minorities which in turn increases the cohesion in minorities. Military profession is seen as a patriotic profession and the job is to defend the country. This is why tensions between majority and minority groups is common in military. Majority group is always suspicious of the patriotism of the minority groups and therefore their representation is always low in military. An example would be in the United States of America when African Americans were not allowed to serve in the army before the Civil War. It was only when it was inevitable that they were allowed to serve in the military. Majority group in most cases feels suspicious of the minority group because they believe minorities

Monna Giovanni and Wife of Bath Essay Example for Free

Monna Giovanni and Wife of Bath Essay The personas crafted by Boccaccio and Chaucer are different. Chaucer’s Wife of Bath receives its recognition from her smart characterization that portrays her as unconventional and eccentric woman with certain strident elements whereas Boccaccio’s Monna is described as a creature of elegance and of high moral stature. Both these women are manifestation of two different faces and facets of the same age. One manifestation of the age is conventional i. e. Monna Giovanni who is utterly loyal and faithful whereas other illustration is unconventional that does take into consideration the conformist norms and values of the contemporary era. Both Wife of Bath and Monna Giovanni hail from higher social stratum. Wife of Bath’s attitude toward men is domineering and she advises other women to do so. She considers them lecherous and mean due to their indifferent attitude toward women. She refers to them as suspicious and lusty-fellows. (234-378) Her own attitude toward men is paradoxical. She is offensive toward them and considers it a good practice to get best out of men. But she expects patience from men in anger and urges them to emulate the well-known tolerance of Job. She expects fidelity from them e. g. she hates the infidelity of her fourth husband but never assure them her own fidelity. In contrast to Wife of Bath’s thoughts toward men, Monna’s attitude toward men is in conformity with the socio-cultural standards. Wife of Bath is does not behave in conformity with the social norms and traditions of the contemporary era. She does not meet the expectations of proper manners of a wife. She married to three aged but well-off husbands in her youth and inherited their wealth. She is of dominant nature and tried to override her fourth husband who was of her age. She had a bad experience with her fifth husband. All of them are now dead but Wife’s hopes are alive to marry anew. Through the summary of her married life (459-462), Chaucer portrays her as clever and selfish woman who unlike the common woman of her age does not marry due to matrimonial and ethical purposes but it was her materialistic desires that make her to marry old husbands. But again her attitude toward marriage is paradoxical as she loves her fifth and last husband due to his expertise in sexual relationship. Wife of Bath has had extramarital relationships as well (lines 461, 467, 476). Unlike Wife of Bath, Monna Giovanni is an epitome of chastity and virtuous. She did not notice the temptations of sentiments and paid no heed to the instigations of her lovers. Boccaccio says in this regard; â€Å"However the lady, no less virtuous than fair, cared not a jot for what he (Federigo) did for her sake, nor yet for him. † She marries and remains faithful to her husband till his death. Furthermore, Wife of Bath takes love and marriage in term of economic benefits and thus equalizes it to prostitution. She uses the economic terminology to denote to the marriage and matrimonial relationships. In contrast to Wife of Bath, Monna considers marriage socio-cultural obligations and takes pride in matrimonial bliss. Her faithfulness to her husband is a result of matrimonial accord. After her husband’s death, she does not usurp his inheritance but forward it to their only son. The only similarity between these characters is their stylish and trendy life. Wife of Bath is a fashionable lady adorned with the grace of the contemporary costumes and ornaments. But Chaucer provides certain references where she seems over-dressed. Monna Giovanni was â€Å"in her day held rank among the fairest and most elegant ladies of Florence†. But we do not find her snobbish and over-dressed. There is a feeling of superficiality about the Wife whereas Monna’s character carries elegance and grace with it.

Graduation Speech -- Graduation Speech, Commencement Address

When I was younger, I would often return home to a familiar question: So, what did you learn today? My answer would always be "nothing" or "stuff." As I look back, I never lied, yet, I never told the whole truth. Many people think that you don't know anything with only 18 years of experience; I think they're wrong. I've learned a lot about myself and others from the relationships I have built throughout the years. I believe my most important lessons were "people" lessons. Those are the ones which could never be taught out of a book or in a lecture; you have to go out and experience them for yourself. I have learned that you'll never know the answer if you don't ask the question. People like you for who your are, even if you wear watermelons on your head at homecoming, tight black leather pants for a fashion show, or get decked out in your parent's old polyester clothes for Disco Day. Everything is a give and take situation and we can never give enough. If you want to be heard, first you must listen. We are all different, yet very much the same.

Empowerment of the Girl Child Essay

I. Introduction In a seminal article in 1990, Amartya Sen suggested that worldwide, particularly in Asia, millions of women were missing from the population totals of many countries. He also noted the alarming fact that the sex ratio for female children in China, India and South Korea is actually deteriorating while the overall sex ratio for females in those countries has marginally improved. Sen argued that the number of women missing in any population could be estimated by calculating the numbers of extra women who would have survived in that society. This would have been so if it had the same ratio of women to men as in other regions of the world where both sexes receive similar care. Given the low ratio of 0.94 women to men in South Asia, West Asia and China indicating a deficit of 6 percent, he surmised that since in countries where women and men receive similar care the ratio is about 1.05, the real deficit is about 11percent of their women. These numbers tell, †quietly a terrible story of inequality and neglect leading to excess mortality of women† (Sen, 1990). In India, the widening gap in the ratio of girls to boys is clearly brought to light in the Census of 2001, confirming a trend that has been in place since 1901. This is most pronounced in the youngest age group, 0-6, thus indicating the scale of injustice as well as the long-term social and economic consequences implied. Ansley Coale (1991) also drew attention to unusually high sex ratios at birth and high female mortality rates relative to males, especially in the early years of life and for daughters with elder sisters. To give a rough approximation of the numerical impact of excessive female mortality, he also estimated the ratio of males to females in selected populations that would exist in the absence of discriminatory treatment of females, and thus the total number of ’missing’ females. For the populations of China, India, Pakistan, Bangladesh, Nepal, West Asia, and Egypt, he calculated the total number of missing females to be about 60 million, a figure lower than.

The Glass Menagerie Criticism Essay - 910 Words

â€Å"The Glass Menagerie,† is a woeful play, plagued by a missing father, a young man walking in the very father’s footsteps, and a mother whose only life is lived in the past. There is one other unfortunate member of this dysfunctional family—Amanda’s daughter, Laura. Laura lives in a fantasy world, afraid to face the reality of her crippled destiny. She exists in a world of glass, pretty and flawless. Laura represents the glass menagerie; this is reinforced by the disjunction of the horn from the misfit unicorn which in turn represents her handicap. The fragile Laura is treated throughout the story as though she is breakable. When she attempts to do something, her family members, â€Å"come to her rescue† and prohibit her from†¦show more content†¦As previously mentioned, the families tend to protect the affected person. Though the families have changed, the person with the disability is affected the most. Their families attribute to thi s—if at first they try to succeed in a goal and those who are meant to support them impede them, then they begin to believe that this is the way it is and that they are unable to succeed whether that statement is true or untrue. This is close in relation to a concept in psychology known as Learned Helplessness. If one encounters many failures in a situation, they begin to believe that this is the way it is and theres nothing they can do to change it. Lauras Learned Helplessness is depicted in the conversation between Jim and Laura. While speaking to Laura, Jim realizes that she has very low self esteem and responds by saying, â€Å"You know what I judge to be the trouble with you? Inferiority complex!† Jim supports his hypothesis by informing her that she is too self conscious and things she worries about really aren’t that bad, but amplified by her imagination. Laura’s vulnerability is exhibited by both her physical disability and her skewed psychologica l perspective of herself. Like Laura, glass is vulnerable. Talk of Laura’s glass menagerie enters in the midst of the conversation between her and Jim. Since Laura’s world centers around her glass collection, she attempts to interject the subject of the glass menagerie between the subjects currently beingShow MoreRelated Comparing the Life of Tennessee Williams and Glass Menagerie707 Words   |  3 PagesParallels in the Life of Tennessee Williams and The Glass Menagerie   Ã‚  Ã‚   Tennessee Williams is one the major writers of the mid-twentieth century.
