Boston Tea Party Essay Example for Free

Boston Tea Party Essay On December 16, 1773, a monumental event took place that was crucial to the growth of the American Revolution. This event was known as The Boston Tea Party, taking place in Boston, a city in the British colony of Massachusetts. Massachusetts Patriots were in immense disapproval on how parliament was trying to monopolize the market on American tea importation granted to the East India Company (Boston Tea Party). The East India Company was a failing British corporation. This Company was on the verge of bankruptcy. They had millions of pounds of unsold tea that sat in warehouses. The idea was to persuade English and colonial consumers to buy East India Company tea to save one of Britain’s largest corporations. In order to make this happen, British Parliament proposed the Tea Act of 1773. The Tea Act allowed the East India Company to sell through agents in America without paying the taxes normally collected in Britain, which allowed the company to undersell even smugglers in the colonies (David Goldfield). What drew major controversy with the Tea Act was that it retained the three pence Townshend duty on tea imported to the colonies. The colonists objected to the Tea Act. They believed that this act violated their rights to â€Å"No taxation without representation,† which meant that they would only be taxed by their own elected representatives and not by the British Parliament that did not represent them. Regardless of what the colonists thought, consignees were selected in Boston, New York, Charleston, and Philadelphia, and then 500,000 pounds of tea were shipped across the Atlantic in September. The first tea ship, Dartmouth, reached Boston November 27, and two more were sent shortly after that. There were several meetings held demanding that the tea be sent back to England with the duty not paid for. Tension was rising when patriot groups tried to persuade the consignees and the governor to accept this approach. On December 16th, citizens, some disguised as Mohawk Indians, pushed toward Griffins Wharf and boarded the tea ships (Boston Tea Party). In a course of three hours they dumped three hundred and forty two chests of tea into the harbor, turning it into a teapot (Boston Tea Party Historical Society). The chests held more than 90,000 pounds of tea, which would cost nearly $1,000,000 dollars today (Boston Tea Party). There were certainly several participants and witnesses to the accounts of what occurred at the Boston Tea Party. Although all of the participants were taking part in the same event, their memories of their accounts do seem to differ. The first thing that I noticed was the number of participants. David Kinnison, the longest surviving participant from the Boston Tea Party, claims that there were only 24 men involved (Boston Tea Party Historical Society). His statement matches up well with Samuel Cooper, a participant that was just 16 at the time, who claims that there were around 20 men (Boston Tea Party Historical Society). Then you have John Andrews, claiming that there were around 200 citizens dressed as Indians. Another thing that seems unclear is the way the ships were taken over (Boston Tea Party Historical Society). George Hewes, a Boston shoemaker and participant, states that they were divided into 3 groups, one for each ship. Joshua Wyeth, also a participant, who was only just 16, also states that they took to the three ships at the same time. On the other hand, the Massachusetts Gazette states that they worked their way from ship to ship, after emptying one ship they would move to the next. There are many differences in the accounts of what exactly happened at the Boston Tea Party, which I think helps decipher the truthful accounts from the fabricated ones (Boston Tea Party Historical Society). Most of the witnesses that were actually a part of the Boston Tea Party had testimonies that were exceptionally similar. I believe the only thing that may have caused them to be slightly different would be the fact that it was a little over half a century later when they were trying to recollect the events. I also think that the participants swearing to secrecy had an impact on some of the misleading information, such as the discrepancy on the number of participants. Most of the participants had mentioned around 20 men being involved, when in fact the number was found to be a lot greater than that. The participants in the destruction did not even acknowledge each other even when boarding the ships, breaking open the chests and dumping the tea, so of course they are not going to be truthful about how many citizens were actually involved. I also believe that some of the information misinterpreted for fabrication might be due to the participant not writing their story themselves. George Hewes account of what happened was written by him, Joshua Wyeth’s account was recorded from his words, Samuel Cooper’s came directly from him also. All of these accounts seemed to be relatively similar; where as accounts that were retold by biographers may have changed along the way. Also, participants stories did not coincide on what time the event was actually over. John Andrews wrote that before nine o’clock every chest was destroyed, but Samuel Cooper’s account placed the end of the destruction at ten o’clock (Boston Tea Party Historical Society). Considering that Samuel Cooper had a role in this momentous event, I would give him the benefit of the doubt as to telling the truth of when the event actually came to an end (Boston Tea Party Historical Society). Another person who played an interesting role in the Boston Tea Party was Paul Revere. Revere felt strongly about the movement toward political independence from Great Britain. He was a very well rounded artisan and intellectual. Revere was a silversmith whose work brought him in close contact with patriots like John Hancock and Samuel Adams. He used his talents to support the colonial struggle against Britain. Revere soon assumed the role of a leader, along with Adams, of the Sons of Liberty. The Sons of Liberty were a secret patriotic organization formed in 1765 to prevent the Stamp Act (Paul Revere). The Sons of Liberty also organized the Boston Tea Party. Revere was also one of the many patriots who dressed up as an Indian and took part in the Boston Tea Party Protest against parliamentary taxation without representation (Boston Tea Party Historical Society). After the Tea Party, Revere was sent by the citizens of Boston to deliver news of the party to the other colonists in New York and Philadelphia. When he returned, he was appointed one of 25 men by the citizens of Boston to stand guard over the tea bearing vessels, in order to prevent the overexcited townspeople from doing further damage to the ship (Facts on Paul Revere). I would say Paul Revere played a significant role in the Boston Tea Party; he played the part of a ringleader and was a very influential role model. The acts that he participated in would not be condoned by Britain. The Boston Tea Party ultimately captured the attention of Parliament and produced a furious reaction. A lot of people in America and also in Britain were surprised about the destruction of property in the Tea Party. Parliament decided that this epic event demanded an immediate display of power. In the spring of 1774, parliament passed a series of totalitarian measures to be known as the Coercive Acts. These acts included the Boston Port Act, which closed the port of Boston until Bostonians paid for the tea and uncollected duties. The Massachusetts Government Act, this act stated that members of the governors council and sheriffs would be appointed rather than elected and limited the number of town meetings that could be held without the governors prior approval. The Administration of Justice Act, which allowed any British soldier or official who was charged with a crime to be tried in England, where they would most likely receive a slap on the wrist. The Quartering Act of 1774 permitted the army to lodge soldiers in any civilian building if necessary. All of these acts were in response to the Boston Tea Party and attempts of Britain to gain royal control. Most colonists referred to these acts as the Intolerable Acts rather than the Coercive Acts, they viewed these acts as a threat to liberty in the colonies. The spirit of protest began to spread, more and more colonists became politicized. They began to realize their common interests as Americans and their differences from the British. America was starting to rebel, but had not yet launched a revolution (David Goldfield). Although, the acts they were taking were starting to have a major influence on America. The Boston Tea Party effected America in many ways. There were a lot of different factors and rebellious acts that eventually snowballed into war, but I would say the Boston Tea Party was the most significant. The passing of the Coercive Acts and parliaments refusal to revoke them led to a great deal of disgruntlement from the colonists. The Boston Tea party most definitely sparked the Revolution, which may have otherwise been delayed or never happened at all.

Aida Rivera GRT 110 Introductions to the Study Aging Dr. Jackie Griswold Video Reaction: 4 Loves, Intimacy and Sexuality 1) Many changes occur in the body between the ages of 45 and 60 as 10 and 25. How changes in young peoples bodies an effect their behavior change that occur in older bodies. Most America seems obsessed with sex and love. The media over flow with sexual image and inurn does they focus exclusively on youth American popular culture the conclude that the young are preoccupied with love and sex the interest in these matters disappears when a person hits middle age some would look for sexual stereotypes would look at television and hardly see an older person involved in an erotic, deep loving relationship you see young people in their 20s and 30s if you look at television commercials reflect advertisers wanting to be aware of how reflect society’s attitudes you hardly see an older person in a television commercial in a erotic situation or loving situation all they do on television all is making coffee or worry about their dentures will fall out commercial it’s nonexistent image stereotypes sex is for young people. The exception the way when older people are show in humorous cast engaging in sex or in relationship of course the golden girl’s older woman brings sexually interested in somebody they may be inappropriate for older woman to still be sexual? All you have to do go to these card shop and they will tell you about your decline how to deal with it sympathy cards about your loss they being in your 30s older people laugh at that is still offensive to see that something that is important in life to find the source of stereotypes about greeting card contemporary some people don’t stop think our culture sex is for reproduction, the people that are preserved as appropriate for ex they’re people of childbearing and ears, people who are healthy, attractive these bring sexual, they are supposed to do sexually, lead to reproduction and negative attitudes in our society about adult masturbation because don’t lead to pregnancy lot people think sex is to connected with pre gnancy negative attitudes about lesbians and gay men because what they do couldn’t lead to reproduction look at our stereotypes, ideas and values about what is appropriate sex it boil down to having socially approved pregnancy and that does not include older people. The competing influences what’s appropriate and what’s not the facts remains that older adults are sexual brings what they do and how they do it is as divers the population itself sex is an ongoing thing as we grow older our sexual and reproductive systems change women and men experience these changes differently the female reproductive system consists of the ovaries, the fallopian tubes, the uterus and the vagina a mature woman every month is ovulating will produce and egg if not fertilized will menstruate the ovary produces along with the egg hormones that are needed by the female body to reproductive structures in fertile situation and these are estrogen and progesterone when a woman ages the eggs within the ovary became resorted and the ovary stops producing estrogen to continue with the normal cycling normal processes an adult woman expects. She will stop menstruating when this condition persists more than a year the woman is termed menopausal the physiological change associated with menopause are affected by a woman’s estrogen levels very from woman to woman the primary source of estrogen is the ovary but women also produce estrogen from their adrenal glands there certain amount of variation individual to individual, the body as it decreases we find that the uterus became smaller, the vagina became drier, the tissues of the vagina became thinner, there change in the breast, some changes in the skin, there organ and tissues react to estrogen and the absence of estrogen changes that ensue estrogen replacement is prescribed by physician for menopausal women there are benefits and risks the benefit of taking estrogen replacement therapy is to control the hot flashes 2) How the experiences of the older adults in the video affected your personal view of aging? 3) Any other comments you have regarding video? Aida I. Ri vera GRT 110 Introductions to the Study of Aging Dr. Jackie Griswold Video Reaction: 7 The social roles implication of that are as fellows is every important to begin with the recognition we’re in the middle of a demographic revolution and stated simply never before in history of our species have many individuals lived so long that’s the demographic background the social roles of implication of that are fellows most of human history we have had roles which are social positions that have rights and duties and expectations associated with them has a fairly clear definition of childhood roles and them of adult roles like parent and marriage partners and economic roles we haven’t had are retirement roles today’s aged are pioneers in time they are creating social roles for a large number of individuals first time in history been old in our soctily mean different things to different people, older people have much autonomy when you think about role of an older person as an attribute thinking is freedom and autonomy most people who are retired wh o launched their children where really don’t have to do anything with anybody they don’t want to do anything with they don’t have to be with people they want to be with nor occupy a role they don’t want to occupy there’s lots of choice operating there which means there won’t be specific roles you can point to and say this is what older people are doing . Friendships are important to older people and especially important for those with few family members, sometime older people take on surrogate family roles for their neighbors in senior housing or retirement communities relatively few people are still working at age 65 freed from the pressures of work they enjoy a wide range to leisure activities some are things they’ve always done other activities are new . As the older population grows accurate information about aging and older people, important increase researchers collect information about social roles through three basic methods observation, interviews and surveys in observational analysis researcher makes a detailed recording of a person’s behavior and interactions with others in an objective neutral manner Dr. Vern Benton give an example and here I’m thinking of the work of Jaber Gubrium at Florida state university he spent a year in a nursing home several years just writing down what was happened and he published his account in a book called living and dying in Murray manor all he did was watch the interaction of the patients in a terminal long-term care facility the interactions of the staff with each other, the staff with the patients, the doctor occasionally came in very occasionally and the administrator from that he come up with a astonishing variety of activities that reflected roles a second way together information interview people and to categorize their responses . Dr. Archly Learned the value of the interview method early in his career the first study that he does to look at the relationship between the job role and the self-concept what he was interested in was the effect of retirement on self-concept of careen women and he picked two different occupational categories school teacher and telephone operators these were the days when mostly women were telephone operators his gone through the traditional sociology literature found that everybody predicted that, you know when people retired this was the end of life as we know it you expected that people retired just dropped off the face of the earth he had all of negative hypotheses what he expected retirement to do to these women , he did he’s first practice interview on a 82-year-old school teacher at end first he said thank I appreciate your answers she said when will you ask about good stuff? He said â€Å"tell me about it† for the next hour and a half he sat there getting writer’s cramp listening to all the good stuff about retirement why it wasn’t a problem for her and her self-concept here cast the interview schedule and did another study looking for both positive and negative out comes that be great, if he done that survey in the mail or sent people to do the interviews or hadn’t done them myself he never would have found those positive effects because he was there to listen a third method for gathering information is the survey the rope and gall up polls are example of well-know national surveys collects data from a representative sample of a relatively large population information is gathered by questionnaire which can be mailed to participants or administered by telephone or personal interview surveys on social roles might ask these questions like are you employed? Are you a Grandparent? You have one or more hobbies? Compared the roles of older men and women suggests it holds a message for young men of today older females characteristically have more roles than 70 to 75 year old males the implication for that at least for college students college men should right now begin diversifying they should begin investing effort in variety of roles in 30 years, 40 years when they retire from a formal occupational role, they will not have to look around and say â€Å"now what do I do† that’s long term-planning understand the behavior of older people may be missing very important information they are always analyzing data collected from people they haven’t talk to the advise students who are doing that to find people who are like the folks who responded to that survey do the interview with them . They understand what they were facing, if they had problem with the question use multimethod they are tool effective looking at social roles, reseacher’s who study the roles and relationship. 2) How the experiences of the older adults in the video affected your personal view of aging? I can wait to see what will happen. 3) Any comments you have regarding the video? Aida I. Rivera GRT11O Introduction to the Study Aging Dr. Jackie Griswold Video Reaction: 8 Families and Intergeneration Relation Changing values as parent or grandparents A popular assumption tends to abandon or distance themselves from older members of the family statistics don’t bear this out. Research shows that about ? f older adults live with or hear a family member, most of those who don’t have frequent phone contact or correspondence a look at the modern family structure shows that is getting more complex with a increase in four and five generation families. The fabric of older society is woven with many distinct and colorful threads approximately 5% of older people have non marry such as the case with Ethel Cooper, she never marry, but she doesn’t regard it, she not sorry. Social work against success marriage, Celestine Eggleston come from a broken home and her own marriage failed, leaving her as the single head of the household, coming from a background where there was not happy marriage long-lived marriage. What we’re exposed in these time not much about how marriage work, what was real. Our history in terms of the fact in early days in quotes-blacks weren’t allowed to marry, were not allowed to really in quotes have family in a traditional sense as a European family would suddenly to be some expectations that there was going to be this family with black male carrying out a particular role that person didn’t understand was bit much, on top that the economic expectation, one didn’t have the education, didn’t have the skills to continue to provide for that family net work was something that moved that black male outside of the family, when we talk about the older black woman bring the matriarch. The social situation there was no choice for her to be stabilizing factor in the family with great pride that one was able to keep that family together it also very sad that had to be, but as the children came and grew things began to change differences over child-raising causing marital tensions. Research tells us that marital distress increases the husbands on his wife, who used to have her realm-a private one now someone who is making demands on her time, she doesn’t enjoy it another body research say exactly the opposite after the initial adjustment period of having the husband home it’s a positive time their leisure time activities their political activities, their traveling time increases and very positive time of increased intimacy and warmth with one another we do need more research. However a person won’t necessarily go directly from being a contributing family member is a example to become completely dependent they talk about Pasqual Capone family said he a example for them, they love him every much, about some of roles older parents and grandparents player within the family as we seen a variety of helping patterns, whether is financial or emotional, support, a good deal of help commonly flows from older to the young generation. If older people became frail can they expect to receive the they need from their families or they became caregivers to their own parent, care giving a term used to refer to the support, financial, physical, emotional that families provide to an older family member especially, when this older family member is frail by frail is one is on longer able to be as completely independent as one would like too. Now when we talk about care given we’re looking at a combination or convergence of demographic and socio-economic term weâ €™re looking at the fact that their older people the fact that there are less children. Women are back to work in the past the majority of care given and care giving is an unpaid job, women who were in tradition sense of what wives were about husbands worked and wives stayed at home. Average age of care givens today’s is 57 or 58 the women grow up in different time than today, there been warning of this term with us last 20 years, but maybe we are not listening the fact that women will not be able to quit a job to take care of mom and dad, because women work for necessity for financial neglect that women are single parents and are divorced a job absolutely not luxury vice neglecting all of these trends so it should be a concern for everyone in our society who will pick up this job of caring for mom and dad. When we know that 80% of the frail are care for not by institutions if not by a family members, we mean women. What will happen to this huge source of free labor is not longer available this mean this is a conflict, if women are no longer able to do this someone has to and it will cost plenty to govement are to provide incentives to families to try to get them to continue to care for our elderly. 2) How the experiences of the older adults in the video affected personal view of aging? There are program that take care them and day care and that every good for them too. And that marriage hard work, but is worth it. 3) Any other comments you have regarding the video? Yes I like video remember me of mi having fun with granddaughter. Aida I.

Rivera Title: Introduction to the Aging Calculating Your Real Age and Your Life Expectancy Calculator: living to 100 life Expectancy Calculator: The Real Age Test 1) What was your reaction to the real age test and the life expectancy age calculated for you? Well I think your age is how you feel if you feel good and young there’s nothing to say about. My calculation of age was 49. 9 went, I’m 50 years, I think I’m doing well. 2) Have you been thinking your age your health or how long you may live? About my age I don’t think much, but about my health I do think a lot with out health your time go faster there nothing better than a good health that, if I want to live long, if God lets me live to 100 years that be good. 3) How might you make changes in your age your life, if your real age is higher than your chronological age to extend your life span and improve the quality of your health? Well my age came good 49. 9, I’m 50 years, but still I have to make changes and improver in, how I eat healthier and exercise more like walk more than I do. 4) What your estimated life expectancy are influence you’re thinking about your career(s) and retirement? No it’s doesn’t change, I think, I’m doing well, I meaning the right thing keep a good health and a family that care for me too. 5) What are implications of your estimated longevity in term of your health and income needs? I hope to have a good health so I can have a income, because if I don’t have a health, I can work and I like to work keep myself. 6) Any other thoughts or feeling about your real age or estimated life expectancy that you want to share with me? Oh yes another test tell me that, I’m going to live 95 years since that good; I hope to keep the good work up. What can I said I feel good. Its good went they said you look young for your age it makes you feel so, so good inside and outside.

Carbon Nonmaterial From Non-renewable Oil Resource Synthesis

Carbon Nonmaterial From Non-renewable Oil Resource Synthesis Synthesis and characterization of carbon nonmaterial from non-renewable oil resources by catalytic CVD Introduction Carbon nanotubes (CNTs) are nano materials that obtain amazing properties, which find effectiveness in wide applications such as gas storage, sensor, catalyst, drug delivery system, and solar cell (Chen et al., 2012; Schnorr Swager, 2011). Carbon nanotube has been discovered by Iijima in 1991 (Iijima, 1991). Then Iijima found that Carbon nanotube exist in two structures single-walled (SWNTs) and multi-walled (MWNTs) carbon nanotube (Iijima Ichihashi, 1993). Typically multi-walled carbon nanotube typeset of joined single-walled carbon nanotube. General CNT’s synthesis methods include arc discharge, laser ablation, and chemical vapor deposition (CVD). These methods share the same principles: either carbon atoms determined from solid carbon sources (such as graphite rods used in arc discharge and laser ablation methods) or carbon-bearing gases (such as hydrocarbons, CO, and volatile solvents in the CVD method). Among these, CVD is the most convenient method to grow all kinds of CNTs and the best choice to produce large amount of CNTs at relatively low cost and with mild growth conditions(Prasek et al., 2011). In chemical vapor deposition, energy is donated to hydrocarbons to break them into reactive radical objects in the temperature range approximately from 500-800 °C, sometimes more. These reactive species diffuse down to a catalyst surface where they remain bonded. As a result, CNTs are formed. The commonly used energy source is resistive heating(Magrez et al., 2010). It is quite clear a few years ago that the effective catalysts for CNTs synthesis are Fe, Co, Ni and their alloys. These catalysts can Growth CNTs in three steps according to Vapor-Liquid-Solid (VLS) mechanism: Firstly, a gas precursor produces carbons which adsorb and dissociate on the surface of the catalyst particles to form elementary carbon atoms. Secondly, the carbon atoms dissolve in the mass of the nanoparticles to form liquid metastable carbide and diffuse within the particles. Lastly, solid carbons precipitate at the outer side of the nanoparticles to form carbon nanotubes. Problem statements Carbon nanotube is one of the most hopeful candidates among all the nanoforms of carbon. However, all the carbon based nanomaterials are synthesized using carbon precursors derived from petroleum sources. It is the required to develop and design techniques that have used waste oils to minimize depletion of petroleum. Few waste oil based precursors have already been successfully used to synthesize multiwalled carbon nanotube (MWCNT) via various techniques. Among them CVD seems to be most appropriate. A CVD system with provision for controlling the input parameters through suitable mechanism is employed for this. In other hand, it may be noted that non renewable precursors consist of a mixture of a number of hydrocarbon molecules. This makes the optimization process for synthesis of CNTs from non renewable precursors highly demanding. The optimization process is complemented by characterization of the CNTs synthesized under different conditions. Characterization of CNTs helps in ascert aining identification of their uniqueness and suitability to different applications. It is expected that only a few of them will satisfy the requirements for a particular application. One of the main targets of the project is to demonstrate the applicability of these CNTs synthesized from waste oil precursors for functionalization technique to be suitable for numerous applications. Objective Considering the environmental effects and depletion petroleum product sources, our efforts will direct to receive waste engine oil and use it for synthesis carbon nanotubes. Therefore, as a first step, it is attempted to design easy and suitable laboratory refining process for waste engine oil to receive quantity of fractions. This outlines the first objective of the project. The second objective is that anticipate utilizing CNTs from the selected waste engine oil precursors. The third objective of the project is to optimize the CNTs synthesis parameters such as; temperature, flow rate, precursor type used, and catalysis type. The fourth objective is presenting a thermodynamic study for CNTs. The final objective of the thesis is to demonstrate the ability of MWCNTs synthesized from waste oil precursors for functionalization and study its dispersion in appropriate liquids. Literature review Liquefied petroleum gas, has been employed as carbon source to produce CNT arrays on ceramic spherical surface in the floating catalyst process into two-stage furnace. Good alignment of CNT has been obtained and the purity is as high as 97.5%. Through controlling the growth temperature, CNTs in aligned form with diameter approximately of 13 nm have been gained. As a result, from synthesize industrial fuel as a carbon source and the ceramic substrate, CNT arrays can be easily produced with large scale and at low cost(Zhang et al., 2007). Multi walled carbon nanotubes were utilized by spray pyrolysis of biodiesel oil which prepared from Jatropha curcas over Fe/Co/Mo catalyst which supported on either silica or alumina. Synthesized MWNTs have been characterized by high-resolution transmission electron microscopy, scanning electron microscopy, and Raman spectroscopy. The Raman spectroscopy suggested that the MWNTs were well graphitized. In addition, abundant MWNTs have been utilized by catalyst which supported on silica nanoparticles(Karthikeyan Mahalingam, 2010). Carbon nanotubes were synthesized from heavy petroleum fractions such as Light diesel Oil (L.D.O.) and furnace Oil (F.O.) by modified chemical vapour deposition method and characterized by Transmission Electron Microscopy and Scanning Electron Microscopy. In this search a locally reactor has been designed for the synthesis and collection of soot from the petroleum material. Then, the soot collected is purified by sohxlet extraction apparatus. After that, the purified CNTs are oxidized with diluted nitric acid. The utilized CNTs have been dispersed in different solvents. Then, the dispersed stability has been analyzed at different temperature and results demonstrates that it is highly disperses in distilled water and acetone in compared to ethanol and methanol. Result shows SWCNTs having approximately 70nm in term of F.O and 90nm in term of L.D.O (Jagdeep et al., 2011). Single walled carbon nanotubes were utilized by a chemical vapor deposition (CVD) method using heavy oil residue as carbon source. Different kinds of metals as catalysts including transition metals (Fe, Co and Ni) and nonmagnetic metals (Au and Pt) are used in the growth of SWNTs. The morphology and structure of the synthesized SWNTs products have been characterized by Raman spectroscopy, atomic force microscopy, transmission electron microscopy, and scanning electron microscopy. The results demonstrated that it is possible to synthesize high quality SWNTs by a CVD method with inexpensive heavy oil residue as the starting material. The diameter distribution of as-grown SWNTs strongly depends on the type of catalysts. It is found that SWNTs grown from transition metals (Fe, Co and Ni) have smaller diameter compared to that of SWNTs synthesized from nonmagnetic catalysts (Au, Pt). This result demonstrates the feasibility of controlling the SWNT diameters by selecting the catalysts. Mor eover, it is found that the reaction temperature is the key factor that affects the formation of SWNTs from oil residue. In our case, the growth mechanism of SWNTs is considered to be different from that of SWNTs synthesized from conventional carbon source (Li et al., 2012). Quasi aligned carbon nanotubes have been synthesized for using waste engine oil (WEO) as the carbon source by thermal chemical vapour deposition. The rich carbon content of WEO was supposed to endorse the growth of the quasi aligned CNTs. Synthesis process has been carried out at temperature of 500 and 570  °C for precursor and CNTs synthesis, respectively, a ferrocene catalyst concentration was 17.99 wt%. Synthesized CNTs have been characterized by energy dispersive X-Ray, X-ray diffraction, electron microscopy, and micro Raman spectroscopy. The ability of CNT samples for emitting electrons has been examined by field electron emission (FEE) analysis. Both Electron microscopy and micro Raman analysis exposed a dense mixture of quasi aligned SWNTs and MWNTs with a moderate ID/IG ratio of 0.90(Suriani et al., 2015). Hypothesis In this project, we hypothesize that malty walled carbon nanotubes can be practically formed by using waste engine oil as non-renewable source. Catalytic CVD will be installed since it is currently considered as the most adaptable and affordable method for growing carbon nanotubes especially with high molecular weight hydrocarbons. Waste engine oil can be used directly into CVD, but it will produce carbon nano materials, which means many impurities such as amorphous carbon, nano fiber, and graphite. Thus, we can use re-refine the waste engine oil process at laboratory to receive many hydrocarbon products and use them as a carbon sources.

Race and Culture in American Films :: Media Latin Americans Movies Film Essays

Race and Culture in American Films "One of the side effects of American cinema was often crushingly brutal portrayals of other races and cultures, depictions that spread to larger audiences than eve before possible around the nation and even around the globe."(Keller,5) The visual images depicted through the video montage "Gringo in Mananaland" support many of Keller's views on the harsh portrayals of Latin@s through American media. The video succeeds in emphasizing the particular roles that Latin Americans played in the early years of film. Latin@s were seen as entertainers that would "appear in a context that makes them either foils to or sex objects of Anglos."(Keller,39) This idea is particularly evident through the specific gender roles that Latin@s played throughout the video. Keller describes the three most common roles for Hispanic females in American film. The role that seemed to most often be filled by the Latinas was that of a cantina girl. Basically a dancing, singing sex object, the cantina girl is a "naughty lady of easy virtue, who is also outgoing and exhibitionistic."(Keller,40) As Keller states, "outside the parameters of romance or sex, there are virtually no roles for Hispanic females. The Latina was portrayed as a pursuer of the Anglo man, always waiting for him to enter her life, and always willing to "discard her Latin suitor in favor of the Anglo."(Keller,40) In general, the Latinas in the video montage were portrayed as sexual temptresses with little respect for themselves or their values. Hispanic males were most often portrayed either serving to the Anglo males or lusting after the Anglo women. The various roles that Hispanic men played in American films were usually limited to negative characters such as bandits or greasers. The depiction of Latin@s in early American cinema is far from accurate and rarely displays realistic living situations of Hispanics. It is evident from both the video and from Keller's descriptions in Hispanics and United States Film that the Latin@s were portrayed as ignorant, uneducated, unproductive people in American films. They were primarily entertainers, and were never placed in real life situations in the Latin American community. Keller's belief that "white Americans believed in the superiority of the white race and depicted this superiority on the silver screen"(32) was clearly evident in the video montage.

New Ways of Learning in the Workplace :: Workforce Work Working Job Essays

New Ways of Learning in the Workplace In today's "high performance organizations," workers must be prepared for continuous on-the-job growth and development. Given the increased age, variety of experiences, and diverse lifestyles and cultures of the working population, it is understandable that adult education practices must move beyond the traditional model of teachers as purveyors of knowledge and learners as passive recipients. Methods and techniques that draw upon workers' previous experiences, link concepts and practices, and encourage reflection and the transfer of knowledge from one situation to another are vital to the learning process. This Digest addresses some of the new ways to learn at work, such as action learning, situated learning, and incidental learning. Action Learning Action learning is a systematic process through which individuals learn by doing. It is based on the premise that learning requires action and action requires learning. It engages individuals in just-in-time learning by "providing opportunities for them to develop knowledge and understanding at the appropriate time based on immediate felt needs" (Lewis and Williams 1994, p. 11). Learning itself is the desired outcome of action learning, not problem solving. It is the learning that occurs in the process of finding solutions to problems that constitutes action learning. It is a type of learning that helps individuals respond more effectively to change. Action learning has been adopted in the workplace as a viable approach to experiential management education and development and an important element of a training and development strategy (Vince and Martin 1993). It involves the members of an organization in group situations with the goal of helping each group member learn through the process of finding solutions to their own problems. Through this process, learners increase their self-awareness and develop new knowledge, attitudes, behaviors, and skills for making changes and redefining their roles within new contexts (Williams 1992). The properties of action learning clarify its relevance to workplace learning (Beaty et al. 1993): Learning is based on the solution of real problems. Learning occurs with and from others who are also engaged in managing real problems. Members of the group are responsible for solving their own problems, unlike those on a project team or task force. Members of the group are concerned with implementing actions, moving beyond the stages of analysis and recommendation. Situated Learning Situated learning is another approach that is receiving attention in the field of adult and workplace learning. In the situated learning approach, knowledge and skills are taught in contexts that reflect how the knowledge will be used in real-life situations.

surgeon general :: essays research papers

There are many leaders in the United States today. These men and women help to form the nation into what it is today and what it will be in the future. One of these important leaders of the United States is the Surgeon General. The Surgeon General has many responsibilities and priorities that form our nation’s Public Health System. These responsibilities and priorities of the Surgeon General will be explained throughout this paper.   Ã‚  Ã‚  Ã‚  Ã‚  According to the Reader’s Digest Encyclopedia the Surgeon General is the chief medical officer for the United States Public Health System. This means that since 1871 the Surgeon General has been the nation’s leading spokesman on matters of public health. The first person to hold the position of Surgeon General was Dr. John Woodworth. Dr. Woodworth put together a group of physicians to assist him with health issues. The Congress recognized these men and women as the Commissioned Corps.   Ã‚  Ã‚  Ã‚  Ã‚  Over the years the position of Surgeon General has changed in many ways. In 1873 the official title of the Surgeon General was changed to Supervising Surgeon General and then back to just Surgeon General in 1902. According to Funk and Wagnall’s New Encyclopedia the Surgeon General was the head of the Public Health System and reported directly to the Secretary of Health. After 1968 the Surgeon General reported to the Assistant Secretary of Health.   Ã‚  Ã‚  Ã‚  Ã‚  The current Surgeon General for the United States is Dr. David Satcher. He was born in Anniston, Alabama on March second 1941. Dr. Satcher, his wife Nola, and his four children live in Bethesda, Maryland. Dr. Satcher received his M.D. and PhD from Case Western Reserve University in 1970. Dr. Satcher is the sixteenth Surgeon General and also the first African American man to hold this position. Fourteen men and two women have held the position since it originated in 1871. Dr. Satcher was sworn in on February thirteenth 1998 and his term will end in February 2002. He also held the position of Secretary of Health from February 1998 to January 2001. He was also the Surgeon General at this time. According to the Official Surgeon General website, Dr. Satcher has many jobs and responsibilities. First off his job is to administer the U.S. Public Health System. This is a group of public health professionals who respond to current and long-term health needs of the Nation. Dr. Satcher also provides leadership and management to the Public Health Service in the field of emergency preparedness and response activities.

Becoming a Police Officer Essay

Although being a police officer can be stressful, it can also be highly rewarding if public service is important to you. (Kara, 1999) When becoming a Police Officer, you are making a commitment to protect your community even if it means giving your life to do it. Despite what some people may think every police officer does their job they way they do it to make sure that your families are safe every night. Just like any job out there now a days you have to have an education. To be a police officer most places are now requiring a two degree. Going beyond a two year degree usually leaves you the opportunity to progress in your field of choice allowing for more job options. Being a Police Officer means that you have to first meet the requirements set forth by the department with which you are applying, have the unique set of skills to do your job efficiently, and you have to have the willingness to further your education to go further in your career. To be successful as a Police Officer there are some characteristics that you need. Some of these characteristics include having a level head, being able to think quickly on your feet, and have the ability to work well under pressure. You have to be able to work well with little to no supervision. This is a skill you need when working undercover and in the field. It is also important that you have self-confidence, and confidence in your ability to make decisions and take the lead in what could be a risky situation. Leadership skills are also important because the people of the community look to you to be able to solve issues and crime related issues. Having the capabilities to be a leader comes very important in the job as an officer. The whole community depends upon your ability to be a leader in their eyes. It’s highly important to have the ability to stay calm in highly stressful situations. If you are unable to stay calm in high pressure situations and emotional intense situations it will become hard for you to as an officer to function on a daily basis. Having patience (which can be difficult at times) and a good set of morals are also important skills an officer must have. An officer must be able to handle situations with patience and good communication skills. These come very handy while interviewing a suspect or even dealing with issues in the community. Having a good set of morals are important because as an officer of the law you must set the example and follow the laws yourself and not believe that you can get away with everything because you are above the law, because you are not. You are an enforcer of the law, so to enforce the law upon others you must also obey the laws yourself. You also should have a good sense of right and wrong to be able to encourage good behavi or to the public. The basic requirements to be a police officer are usually about the same, because most follow the civil service regulations when hiring officers. These requirements would include: Being a United States citizen, you have to be at least twenty-one years old, have a high school diploma or equivalent education, possess a valid driver’s license, and have no prior convictions. Now these are just the basics, most departments generally have more requirements, for example a lot of departments now require that you have at least an associate’s degree in criminal justice. Before you can begin working in a department as an officer you are generally required to attend a police academy which you must complete and pass to be qualified as a Police Officer. When you go through the police academy you are generally there from twelve to fourteen weeks, while there you must pass a physical fitness and written exam. While at the police academy educational wise, you will learn state ordinances and local laws, working with the public, constitutional laws, accident investigation, incident reporting, civil rights, mental preparation for hostility, and criminal psychology. Like most jobs you can learn all you want about a job but, you learn best by doing. Because police jobs are dangerous jobs they require specific training to succeed in the field. Work experience is done under the supervision of a training officer. The on the job training includes: using firearms, responding to emergencies, controlling traffic, CPR and first-aid, self-defense techniques, apprehension techniques, risk assessment, and role playing. All training is essential to be the best you can be at being an officer. All the training that is endured is important for you to be the person the community needs you to be. There are several opportunities for advancement in law enforcement. The police force ranking is clearly structured and goes as followed: Police constable, sergeant, inspector, chief inspector, superintendent, chief superintendent, assistant chief constable, deputy chief constable, and chief constable. Police constables have to complete a two year probationary period before they can be eligible for higher ranking. When the probationary period is over police constables are then able to apply for specialist units such as the fraud squad, fire arms, drug squad, child protection, criminal investigation department (CID) traffic, mounted branches, dog handlers, and underwater search units. Becoming a police officer is a process; you are tested physically and mentally. Being a police officer is an important job because those people are there for you, your family, and the community. Not only is education a requirement to being a police officer, but furthering that education will open up more opportunities in that field. To be a police officer it takes a number of skills to be the best you can be at your job. References AGCAS. (2012, January). Police officer career development.
