The Unknown Bacteria Plate Chosen - 926 Words

Unknown Bacteria I. Introduction The unknown bacteria plate chosen was plate #2. It was identified to be Micrococcus luteus. It is a gram positive, Coccus bacteria that is commonly found in dust, water, soil, and the air. M. luteus also thrives in the human mouth and upper respiratory tract. Sir Alexander Fleming discovered it in 1928 before he identified penicillin. It is part of the normal flora on human skin as well as other mammals. Since it is part of normal flora it is normally not pathogenic, but can become opportunistic in an immune-deficient person. It has been known to cause septic shock, UTI’s, and even pneumonia. Micrococcus luteus is both urease and catalase positive. It does not utilize tryptophan for indole production. It is a facultative anaerobe. Mobility is not present for this bacterium. Starch is also not hydrolyzed and oxidase is not present. II. Materials and Methods The Gram stain was used to determine if the bacteria was gram positive or negative. A negative test shows a pink color and a positive test is a purple color. When a bacterium is negative it is because it has an outer membrane and a thin layer of peptidoglycan that is much harder to stain. A positive bacterium has a thick layer of peptidoglycan and no outer membrane that can be penetrated by crystal violet. To perform this test, a small drop of water is placed on a clean microscope slide. A metal loop that has been properly sterilized in the blue flame and allowed time to cool is used toShow MoreRelatedIdentifying And Identify Two Unknown Bacteria From A Mixed Culture1737 Words   |  7 Pagesand identify two unknown bacteria from a mixed culture.

The Epic Of Epic Heroes - 2181 Words

From King Arthur, to Beowulf, to even Achilles, characters that embody the traits of epic heroes represent an integral part of ancient literature. In fact, what would literature be without epic heroes? How different would The Odyssey be if Odysseus never went on his epic journey? Would the epic poem Beowulf still be read today if the character Beowulf never challenged Grendel and Grendel’s mother? In the story, The Epic of Gilgamesh, characters, both men and women, exhibit characteristics that could be considered heroic, but do they represent epic heroes? Applying a character analysis to The Epic of Gilgamesh will not only help define their status as epic heroes, but will also reveal the purpose of the character, what the character†¦show more content†¦He also raped any woman that he wanted, whether she was married, single, or even on her wedding night. While this may have been part of his divine privilege, it still reveals his lack of respect for women. Gilgamesh was also incredibly over-confident and selfish, making decisions about his country without interacting with his people or getting their opinion. This cockiness is shown while the harlot is describing Gilgamesh to Enkidu by saying, â€Å"He is wise to perfection, but struts his power over the people like a wild bull† (Gilgamesh 79). However, despite these human flaws, Gilgamesh does represent an epic hero. One factor that applies to many epic heroes would be their connection to the divine, and Gilgamesh represents that through his bloodline. He is the son of a goddess, therefore giving him abilities that separate him from the completely mundane. In fact, due to his divine heritage, Gilgamesh is considered, â€Å"strong and awesome to perfection† (Gilgamesh 75). However, despite being the son of a goddess, Gilgamesh is limited from being completely divine due to his father being human. More specifically, Gilgamesh is the â€Å"offspring of Lugalbanda† (Gilgamesh 75) , which, in other words, means young and fierce king. Lugalbanda was an earlier ruler of Uruk, which allowed Gilgamesh to inherit the throne. It is his connections to both

Nature and Human free essay sample

Nature and human have always interacted throughout history, and the interaction of the two forces has evolved into a series of demands that people have put on nature to survive and develop. By contrast a minority of people have questioned the state of things and tried to figure out how humanity and nature can interact and develop together, and through their questioning they have come to define their idea as ecological cosmology. To begin with it is important to always start from the word itself, as each and every word has a meaning firstly by itself, and then it can acquire more depth through its use in a given context. Ecological cosmology comes from the Greek oikos and logos , these two words define respectively a dwelling place and a discourse or intelligible manifestation. Ecological is something that deals with the environment in which one is, and on what can be said of that environment. Cosmology is instead related to kosmos or order and its intelligible manifestation, thus it can be said that there is an intelligible order or a logic to how things happen. Ecological cosmology can be seen as the order in which things happen in a given environment, and many versions of it exist, as many people with different backgrounds thought of defining the order of things depending on how themselves and their environment are shaped or are going to be shaped. â€Å"The mythological process deals not only with natural objects, but with the creative potencies whose original product is consciousness itself. So it is here that our expl anation breaks through into objectivity and becomes wholly objective (Shelling, 207). Ecological cosmology has been seen as a mythological force, of creative and positive nature, which comes to define elements of nature, and the perceptiveness of them that people come to have. Talking about nature and ecological cosmology becomes as a result part of a discourse that does not limit itself on discussing how a myth can come to be seen in nature, but also on the fact that a myth becomes an object that people can see in nature and attribute a representation to it – that can be viewed on how people see and define elements and objects within nature and how these objects happen to effect the relationship of mankind and nature. It is worth noting that no moral cause ever got very far that could not speak to religious conviction, drawing on the deeper sensibilities that guide public opinion even in our more secular era (Scully, pp. 12-13). † Throughout the evolution of mankind, people have gone through different phases of ecological cosmology and at one point or another – ecological cosmology happened to be tied in with Christian principles to be viewed as something more approachable as a way of being within nature, rather than the sole use of na ture. For instance at one moment or the other nature has been perceived as an element of Gods creations, in which people were to live abiding the rule of God, and using nature to further mans position on earth. It is interesting to see in fact how the evolution of Christianity has put people first as representation of Gods will on Earth and then after only at a second time, people have seen nature as something to needy of care. Interestingly enough nature has been for most part of humanitys history the giver in a relationship – care towards it instead has always come at a second time and out of the feeling of guilt rather than respect in a balanced environment, as solely humanity and people have seen balance in the goods generated by nature. It is also worth noting that in times when nature got attention it has been mostly the attention of an intellectual elite, and even in cultural movement such as romanticism – attention to nature and its care have solely been regarded as a pastime, like for example when in the late 1800s the British high society started to find interest in gardening and even that has been solely related to an elite status. Intellectuals and elites have been able to move society forward within limits, but sadly those limits havent been altered too much or challenged even within those circles. Results have been many compared to a level of development that mankind has obtained out of the use of the many fruits of mother nature, it is interesting to point out that those phases of interest in nature have been mostly occurring after intense industrial developments periods – and because of that they have become the hadow after the light of successes of science and scientific research. Yet those phases have brought onto people the harsh reality and needs that follow advancements as those have a price, and results that not only affect increasing social conditions, but also that affect people with challenging bad health conditions and a state of realization to people that at any of hose junctions realize the damages in natures ecosystems. Furthermore it is interesting to realize how Renaissance, Enlightenment, Romanticism, Impressionism and Expressionism have challenged the status quo on a cultural level. All those cultural, artistic and elitist movements have allowed men to have a reality check with its contemporary community, and given they all developed a specific code in any given location in which they took place. They have started a constant discourse that has led people to ones realization nature and humanity need to re-balance one another – and the balance to be found is not as easy to come by as it is expected even after constant technical development in both industrial and artisanal methods, the situation people are put in front of holds many challenges, and the biggest one of them involves a change in understanding and dealing with nature all together. erably failed.

A Review of Marxs Communist Manifesto free essay sample

Marx’s most relevant argument regarding this view of capitalism or being only for 10% of the population is when he say’s â€Å"According to this, bourgeois society ought long ago to have gone to the dogs through sheer idleness; for those of its members who work acquire nothing, and those who acquire anything do not work. † Marx believes that the working class should be rewarded more for the hard work they put in vs the rich who are wealthy and do not have to put in as much work. The strength I see in this argument is that you can see a lot of people who put in hard work however aren’t rewarded as such and capitalism promotes people to be greedy and want more. However sometimes people cannot tell the value of the hard work that is being put in. , and make bad choices like getting into to much debt and then blaming the rich and their bosses for their problems instead of being creative and thinking how they can become more productive. We will write a custom essay sample on A Review of Marxs Communist Manifesto or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page . My personal opinion is this struggle of the classes will always continue because it is in human nature to want more therefore makes the argument that 10% of the population have all the wealth is weak. I feel that hard work should be rewarded in a society and taking private property away is not the way to solve the problem, because there are loopholes that can result in this view of communism in which work and rewards is split between people. The negative result would be some people may not work as hard as others and therefore don’t deserve the same amount of reward. For an economy to work properly reward for the level of work and value that is put in is essential, I truly feel that someone’s mind can prove how much they contribute to society and rewarded as such.

Economic and Sexual Oppression of Female Slaves essays

Economic and Sexual Oppression of Female Slaves essays The article Female Slave Resistance: The Economics of Sex by Darlene C. Hine, focuses mainly on showing that slavery was equally as harsh for females as it was for males. In the article, Hine shows that female slaves, unlike male slaves, faced two forms of oppression. She explains and gives examples of the three main forms of slave resistance used by the females. While all slaves faced economic exploitation, women were also forced to deal with the hardships of sexual oppression. Sexual oppression was exemplified through females being required to take care of their masters children, many times instead of their own. In addition, the better-looking slave women were sold for much higher prices and often forced into having sexual affairs with their white masters. Many of the more attractive slaves were sold for prices that exceeded the amount an owner would be willing to pay for a strong, well-built field worker. In 1857, in the Memphis Eagle and Enquirer, a female slave was said to be so surpassingly beautiful that a bid of $5000 was offered and not accepted. Due in part to this sexual oppression, several different forms of resistance were practiced by the female slaves. The most common form was sexual abstinence. One way sexual abstinence was obtained was through women avoiding sex with their owners. Linda Brent, a former slave and author of Incidents in the Life of a Slave Girl, used the simple fact that her grandmother was still present on the plantation to put a halt to sexual advances made towards her by her master. Her grandmother was a former slave whom her master was afraid of. The second way sexual abstinence was practiced was by the females resisting sex and marriage to other slaves in hopes that they could eventually get married and raise their children in a world free from slavery. Another way females showed resistance towards slavery was through abortion. Because slave wo...

Recession and Consumer Spending Habits in the Clothing Indusrty Essay

Recession and Consumer Spending Habits in the Clothing Indusrty - Essay Example They also spend in different ways due to the recession. As borrowing becomes harder, consumers are more likely to make spending sacrifices. â€Å"People are clearly starting to get a sense that things are not as easy financially as they once were,† said Peter Ayton, Chief Statistician at Mintel. Recession not only affects how much consumers have to spend, but also how they behave. This project investigates changes in womens spending habits and examines how they will change in the future. The project considers a number of essential questions. Will womens spending behavior change when the recession ends? Or will they revert back to their old spending habits? Will consumption be back to the same level as years past? Will women spend less, delay purchases or trade down to cheaper alternatives? Economic recession can be defined as a significant decline in economic activity lasting more than a few months (NBER, 2009). The United Kingdom has been in recession since July 2008. This was prompted by many problems, including: The increased levels of unemployment and high levels of personal debt, mean consumers are feeling the squeeze. During recession it’s a normal propensity of consumers to cut down on spending and save money. The decline in consumers spending is due to decline in consumer confidence levels. The decline in confidence levels may be caused by unemployment or a financial crisis. Therefore, businesses are forced to lower their prices to attract consumers. When prices decrease, consumer spending capacity increases. In terms of profit and human capital, the recession has negatively impacted many industries. Prominent among the industries hit by the recession is the clothing industry.

Instrumentation paper - Essay Example This absence of national statistics for recidivism does not necessarily mean, however, that the phenomenon is non-existent and is not a concern. In fact, recidivism among juvenile offenders merits special attention considering the prevalence of drug use among offenders, regardless of whether they are adult or juvenile (Bureau of Justice Statistics, 2007; Wei, Makkai & McGregor, 2003). Further, three general trends bared by Spiess and Fallow (2006) on the drugs and crime connection sparked interest in the focus of this concept paper : (1) the prevalence of testing positively for drug use among apprehended offenders; (2) the high incidence of offenders who tested positive on drugs when their crimes were committed; and (3) addiction being a common trigger for offenders to commit crimes to in order to support their addiction. The third trend bared in the Spiess and Fallow (2006) study points to a well-established link between crime and drug use. In fact, three-quarters of crack and heroin users confessed that they commit criminal acts to sustain their addiction (Home Office, 2008). Goaded by the various accounts leading to a connection between criminality, in general, and recidivism, the intent of the proposed study is to gather research evidence on the effects of mind altering drug use and abuse to juvenile recidivism . Juvenile offenders/recidivists. Results of the study will be of greatest benefit to juvenile offenders and recidivists, by way of its contribution to the knowledge base of juvenile problems and the suggestions which will be formulated as output or recommendations of the study to assist youth offenders in realizing the importance of freedom, healthy and drug-free living, education, a personal relationship with God and acceptance back to free society. Correctional Institutions. Management and staff of correctional institutions will find significance in the proposed output of this study, as the suggestions and the new knowledge
