Mergers and aqcuisition Essay Example | Topics and Well Written Essays - 2750 words

Mergers and aqcuisition - Essay Example Since Bentley has somehow gained fame after operating with eleven stores in Southern Europe, Zeta's should look for 24-year AA bonds to determine the discount rate. Judging by the present status of Bentley in the Southern European market, the discount rate Zeta's should use to assess the value of Bentley for their equity holders should range from 5.0%-5.25%. At this low discount rate, they generally have a much shorter period concerning their liabilities. Furthermore, a discount rate of that range is competitive enough to acquire Bentley if Zeta's other competitors for Bentley acquisition uses a higher discount rate. Zeta's also have the advantage since they have operated for years and gained patronization from retail stores in London and Newcastle. Thus, using a lower discount rate to assess the Bentley's is a safe way for their excess cash. By doing so, Zeta's is being prudent enough. If they take the bond rate, Bentley equity holders would actually overview it down for prudence. A pparently, it is quite difficult to get a good AA measure for acquisition and bond yields. Markova (2001) states that if a company uses a discount rate of such range, the competitors tend to overlook the rate and thus t discourages them to continue bidding. Terminal value is defined as the value of any item at the end of a particular time phase. For instance, the terminal value may include the value of a fully depreciated asset and the maturity value of a bond (Bergstein, 1998). Based on the Table 1 of Mr. Sharpe, the terminal value is 8.5 million. The terminal value that should be used in order to evaluate the cash flow of Bentley is satisfactory enough for Zeta's to gain full acquisition to it, which has principally been driven by the market. Since Bentley has somehow gained fame after operating with eleven stores in Southern Europe, Zeta's should look for 24-year AA bond. At this terminal value, they generally have a much shorter period concerning meeting the demands of their liabilities. Furthermore, a Bentley's terminal value for 2005 which is expected to grow by 5% in 2006 is competitive enough to acquire Bentley if Zeta's other competitors for Bentley acquisition uses fashion retail items using their own names. Since Zeta's is j ust planning to start using its own name, Zeta's have the advantage since they have operated for years and gained patronization from retail stores in London and Newcastle. Thus, using a lower discount rate to assess the Bentley's is a safe way for their excess cash. By doing so, Zeta's is being prudent enough. If they take the bond rate, Bentley equity holders would actually overview it down for prudence. Collateral, which consists of securities that could be sold by the Reserve Bank if the borrower fails to pay back the loan, limits the Fed's (and therefore the taxpaying public's) risk exposure. Acceptable collateral includes, among other things, U.S. Treasury securities, government agency securities, municipal securities, mortgages on one- to four-family dwellings, and short-term commercial notes. Usually, collateral is kept at the Reserve Bank,

Cuban Rumba Essay Example for Free

Cuban Rumba Essay Cuban music is a combination of genres and styles, which encompasses quite a long history. Cuban music has been molded by the music and voices of Latin America, Europe, and even Jazz. Of course, Spain and Africa did also have an evident influence on the music as well. There are many different types of Cuban music; all of which is meant for the soul to enjoy. Rumba is a actually a secular folkloric form of music, which consists of drumming, dancing and singing of both African and Spanish languages that has been performed for ages. The rumba term or influence is actually derived from the 16th century when black slaves were imported from Africa, and the word Rumba can cover a variety of terms such as Son, Guagira, Guaracha, and Naningo. However, the exact meaning of the word varies from location to location. Still, it is strongly evident that the Cuban Rumba dance hails originally from Africa where the native Rumba folk dance was essentially a sexual dance that was vigorously fast with strong and forceful hip movements as well as sensually aggressive attitudes on the part of a man and a defensive attitude on the part of a woman. The music, itself was played with a staccato beat, keeping up with the thrusting and vigorous movements of the passionate dancers. Instruments that were also included were the marimbola, the claves, and the drums. The Son was the popular dance of middle class Cuba. It is, in fact, a modified slower and even more refined version of the native Rumba. The instruments are basically still the same as are the movements. However, they are toned down a bit. And, even slower than this dance is the Danzon. The Danzon is the dance of wealthy Cuban society. In this dance, very small steps are taken, while the women producea very subtle tilting of the hips by alternately bending and straightening the knees. The dance known in the United States today as the Rumba is a composite of several dances popular in Cuba, including the guaracha, the Cuban bolero, the Cuban son, and the rural rumba. All of the dances have very similar rhythms that can be traced back to religious and ceremonial dances of Africa. The same pulsating dance rhythms may still be found in parts of Africa, but the dances have been altered by contact with other cultures and races. For example, The rural rumba is a pantomimic dance originating in the rural areas. It depicts the movements of various barnyard animals in an amusing manner, and is basically an exhibition, rather than a participation dance. Both the Cuban son and the Cuban bolero are moderate tempo dances in traditional ballroom form. The guaracha is distinguished by its fast, cheerful tempo. Ten after Americans modified the tempo of the Cuban rumba, later band leader Emil Coleman imported Rumba musicians and dancers to New York but no interest developed. Real interest in Latin music began about 1929 as a result of increased American tourism to Latin America. In 1935 George Raft appeared with Carole Lombard in a movie called Rumba in which he played a suave dancer who wins the lady through dancing. Rumbas unique styling and unusual musical rhythms immediately captured the fancy of ballroom dance enthusiasts, and it has retained its popularity to the present time. The Cuban style is characterized by forward and backward steps. The American version is done in a box pattern with Cuban motion as its chief characteristic. Cuban motion is a discreet, expressive hip motion achieved by bending and straightening the legs and carefully timed weight changes. American Rumba is one of the most popular ballroom dances today. The rumba itself refers to several Latin dance forms, which can all differ greatly. Almost all rumba dances are meant to infer the sexual relationship between partners. The moves can be subtle or quite obvious, which is all depending on the type of form danced The Cuban rumba is very different than what one would see in a ballroom dancing competition. The dance is highly energetic and was thought to have derived directly from the dancing of African slaves from around the West Indies and the Caribbean. Dance historians date performance of this form of rumba back as early as the late 16th century. Some of the moves are so suggestive and frank, that the dance was often considered unacceptable in the countries it was performed, and was actually prohibited. The Cuban rumba requires a high degree of athleticism, as it is very fast. The dance represents a seduction attempt on the part of the male, with the female standing resistant to the man’s charms. This form of rumba frequently includes acrobatic moves, like handstands, flips and cartwheels, usually performed by the male. In order to achieve sexual gratification, he must impress his female partner. The second part of the Cuban rumba usually brings the dancers close together, and the movements are easily indicative of sexual longing. There is much what one might deem â€Å"inappropriate† body contact when the couples connect, and many moves indicate various sexual positions with the male clearly dominant. The partners are often hip to hip in dance connections. This type of form is rarely seen except in exhibitions since it requires a great deal of space to perform it properly. The dancers are mostly apart, and utilize a significant amount of floor space while performing very different acrobatic moves far apart from each other. In conclusion, today the rumba is known to be one of the most popular ballroom dances because of its interesting movements and rhythms. The Cuban Rumba is one of the most important and popular folkloric styles still played frequently in Cuba at musical parties. This is one of the most difficult and syncopated of all Cuban musical styles in popular folklore, both in its music and dance. Guaguanco is a medium paced rumba style that is danced by a couple.

Comparing Einstein and Other Ccreative Geniuses :: Compare Contrast Comparison

Comparing Einstein and Other Ccreative Geniuses The author Banesh Hoffmann wrote the essay "Unforgettable Albert Einstein," and expresses his admiration at Einstein’s innate ability for getting to the heart of a situation with simple logic. This ability was the secret of his scientific discoveries. Einstein once made a statement that when Mozart composed music, he found the beauty that was already there waiting to be revealed. This one ability was characteristic of Einstein’s findings. He was able to reveal what already existed but had not been discovered. Whether or not he was using every day experiences or working on more abstract projects his approach was the same. He was able to seek and find the simplest answer to a task or a formula. In one situation Einstein asked Hoffmann if he knew why a man’s feet would sink in dry or wet sand but not in damp sand. He was unable to give him an answer. Einstein explained that surface tension caused by tiny amounts of water pulled the grains of sand together. Because of the friction that was caused, this made the surface hard to move. Einstein’s way of thinking was so simple, that most people would overlook the obvious answers that he would reason out. The simple and curious question that Einstein asked himself was whether a light wave would seem stationary if one ran abreast of it. This question would later lead him to explore and to discover the principle of relativity. An easy example of this theory is the illustration of when you stir a stick in water. It does not matter if you are standing still or moving in a boat. The waves once made by the stick remain the same. It was through questioning and observing that Einstein was able to come up with the solutions that revolutionized physics. I can relate with revealing something that has not been uncovered when I work on artwork. I have experienced this when the painting seems to evolve. I might start with a simple feeling or emotion and then I set into action the birth of a new creation. I have also painted a person that I have not met. Later when I meet the person in my painting I am surprised. The person had always existed, but had not been revealed to me yet. The invention of perspective was discovered in the 15th century.

Oppression among First Nation People: Canada

Oppression among First Nations peoples in Canada The detrimental enforcement of colonialism sparked an era of oppression that has altered, even destroyed years of cultural and spiritual traditions by creating a forced lifestyle that changed the face of First Nations peoples forever. Forced European culture resulted in the diminishing of Firsts Nations values and rights. A cycle of social, physical, and spiritual obliteration resulted from the dispossession of First Nations lands and the implementation of foreign methods of government.Poverty, poor health, and substance abuse are some of the long-term side effects that came about from this oppression. European settlers came overseas, unwelcome into First Nations territory with absolutely no respect for their traditions and ways of living. Over time children were taken away from their families and native homelands to attend residential schools; Native students were given new names and taught to speak English. Residential schools attemp ted to brainwash First Nations children to erase their native culture and traditions.First Nations peoples were defenseless under the power of the Europeans; their rights were ignored and their values were completely demoralized. First Nations peoples were forced down the path of violence and educational failure, which eventually led to poverty. These effects were a direct result of the disrespect and insensible attitude put forth towards First Nations peoples by the European settlers. The introduction of Residential schools to the First Nations peoples of Canada was a system that began in New France in 1620, and was known as â€Å"the experiment of education of Indian Children in residential establishments. (Timeline: Canada’s Residential School History) These schools had a system that was based upon the idea of â€Å"kill the Indian, save the man† (Capt. Charles Pratt, founder of the Carlyle Indian School. ) European authorities were trying to Europeanize the First Nation occupants of Canada by instilling in the minds of young First Nations children the beliefs and values of the European culture. The Clash of two different cultures brought upon destructive trauma amongst the First Nations peoples and their future.The government formed a rule that prohibited the First Nations people’s ability to develop their own culture through their rich traditions. Cultural genocide resulted from years of oppression, and social violence. According to Dr. Leslie Korn, â€Å"Community development that is not self determined precipitates intergenerational trauma in individuals and communities. When this occurs people suffer loss and grieve over ways of life. Families divide and rituals of celebration and healing lose meaning† (Dr. Leslie Korn: Community trauma and development).The development of a culture is jeopardized when change is implemented on a certain group by another group. This reflects the result of European influence on First Nations p eoples. By 1870, the government and missionaries shared the same objective of lowering First Nations children into the reaches of society. By 1920, First Nations children aging from 7-15 years were forced away from their families by priests, Indian agents and police officers as it was now compulsory to attend residential schools. As the years moved along, residential schools slowly faded away.It wasn’t until 1980, where sexual, and other forms of abuse were finally removed. In 1996, the last residential that was federally ran was closed. Most First Nations children, from birth, are surrounded by the attitude, and social obligation of being faithless. The short story Traplines, written by Eden Robinson, is about a young aboriginal boy named Will. Will is falling deeper and deeper into a dark lifestyle that seemingly has no hope. Surrounded buy substance abuse, alcoholism, physical and emotional abuse, Will is caught up in a trap that many aboriginal teenagers misguidedly find themselves falling into.Will is an adolescent teenager that seems to have a silent side of him that wants to change his life. Will doesn’t partake in alcohol or drug consumption, but seems to be desensitized to what is taking place at home and in the community. Will contemplates whether or not he should take the offer put forth by his English teacher, Mrs. Smythe, to move into her and her husband’s household and receive a priceless opportunity for a better start to his life journey. An opportunity that offers much safer and more rewarding lifestyle filled with love and morals.It seems Will doesn’t feel deserving of that deliverance from the violent, detrimental lifestyle he is surrounded by at home. The frequent abusive confrontations Will experiences at home are evident in the text, â€Å"Are you a sissy? I got a sissy for a son. Look. Like cutting up a chicken see? Pretend your skinning a chicken† (379). Will’s father is verbally abusive when Wil l shows the slightest discomfort towards skinning the marten they had trapped. Accompanied by abuse, alcoholism is also evident in the text.Wills explains the tendencies of his parents on the weekends, â€Å"They’ll probably find a party and go on a bender until Monday, when dad has to go back to work† (380). This shows that his parents who are supposed to guide him and raise him properly, would rather waste their weekends away by drinking and doing drugs. Will is forced to stay at his friends house when his parents are drinking in order to avoid the violence that follows alcohol, â€Å"I’m not going home until tomorrow, when mom and dad are sober† (388). In doing so, Will is exposed to watching his friend smoke crack.When confronted by his father about the offer presented by Mrs. Smythe, Will is immediately accused for telling her about the abuse occurring at home. Will’s father uses intimidation to overwhelm Will with fear towards sharing with ot hers what takes place at home. Instead of apologizing, and sensing that his son may not want to live at home anymore, Wills father shows anger towards Will. All of the conflicts involved in this short story are a direct result of hundreds of years of colonialism and oppression. The European system that was taking over First Nations peoples and their lands was that of patriarchy.A male dominated social system brought about massive sexual exploitation amongst First Nations women; prostitution is a graphic example of how deeply patriarchy has wounded the lives of this particular group of women. First Nations women, and men for that matter, did not have the power to overcome the forceful European invasion. Prostitution in First Nations women is obvious evidence of oppression and colonialism that is still very visible today. Ever since the first European contact, First Nations women have been sexually exploited.The first brothels in Canada were set up around military bases and trading po sts, European men demanded sexual accessibility to the defenseless First Nations women. In order to supply the business of prostitution, a low self esteem and demoralized group of women is required. Through the power of colonialism, the oppression involved allowed the First Nations women to fall into this lifestyle. Colonialism, childhood sexual abuse, childhood physical abuse and neglect, family addictions, husband violence, and alcoholism are all vital ssues that lead First Nations women into prostitution. Lorne Crozier’s â€Å"Dark Ages of the Sea† reflects First Nations peoples as a metaphor of being children that fall into wells, â€Å"there was a time when / children fell into wells† (6-7).This reflects First Nations peoples helplessly falling to the power of the European invasion. A race of people who had no education about the effects of what was happening to them, hopeless like a child falling into a well. When Europeans came overseas and found this new land, they were blind to the ways First Nations peoples lived their lives: nd a faith in things invisible, be it water never seen or something trembling in the air (12-15). The excitement of the European people when finding this new land blinded them towards the rights of First Nations peoples. The new waters travelled to arrive at this new land, was the â€Å"water never seen† (13-14). Regardless of what happened to the First Nations peoples and the land that is rightfully theirs. Sensing opportunity, the Europeans wanted to expand into this foreign land they have stumbled across, â€Å"something / trembling in the air† (14-15).Once realizing the unstoppable power of the Europeans, the First Nations spirits were severely damaged, â€Å"We are born to fall / and children fell† (16-17). This resembles the wounded spirits of the First Nations peoples, slipping into the realm of violence and abuse. The surviving members of the First Nations community passed along the stories of suffer and change that came about through the establishment of colonialism and oppression, â€Å"Some surviving / to tell the tale† (18-19).Like a new born calf whose mother passed at birth, blinded and wet, experiencing a new world outside its womb with no guidance; the First Nations peoples were abruptly introduced into a new world, blind towards the harsh reality in which the Europeans were about to instill upon them with no guidance, â€Å"Wet and blind with terror / like a calf† (22-23). Over the past 400 years, First Nations peoples have been struggling to improve their lives. Re-establishing old traditions and values that have been lost throughout years of oppression has been a very slow process.With the help of non-First Nation peoples in Canada, realizing the detrimental damage that has been caused, there are establishments and groups all across Canada joining the fight to replenish what has been torn apart. The teachings and rich traditions tha t the First Nations peoples have developed are being shared and taught at a rate that is increasing as time passes along.Works Cited â€Å"Timeline – Canada’s Residential School History. † virtualmuseum. ca. virtual museum, n. d.

Analyzing The Theme Of Nature In Literary Devices English Literature Essay

The subject of nature is really of import to each of the texts to be discussed in this essay: The Fat Black Woman ‘s Poems by Grace Nichols ; Death of a Salesman by Arthur Miller and Wide Sargasso Sea by Jean Rhys. In a sense, the fact that each work is created within a different literary genre to some extent dictates the indispensable differences amongst them. However, this essay sets out to analyze how, in add-on to comparing literary devices, nature is used as a different jussive mood in each of the selected texts. Throughout the drama, Willy escapes back into his memories and it is profoundly important, hence, that the countryside is allied to this: ‘I was driving along, you understand? And I was all right. I was even detecting the scenery. You can conceive of, me looking at scenery, on the route every hebdomad of my life. But it ‘s so beautiful up at that place, Linda, the trees are so thick, and the Sun is warm ‘[ 3 ]Loman both belongs in the state and out of it because he has merely used it, as he has used both things and people, to acquire in front. The fact that he has been unsuccessful is hence a treachery of his ain and a generic dream that is ne'er fulfilled nor justified, merely as the narrative he begins to state Linda, his married woman, ends non in revery on the idyllic, as it started, but on loss of control: ‘all of a sudden I ‘m traveling off the route! ‘[ 4 ]Miller uses nature, hence, as an emblem of Willy ‘s supplanting: ‘Many of Willy ‘s activities can be seen as extremely symbolic. He workss seeds merely as he workss false hopes: both will decease and ne'er come to fruition, mostly because the house has become excessively hemmed in by the metropolis. ‘[ 5 ]In add-on, a farther lost dream of Willy ‘s has been connected with nature, that of his brother, Ben ‘s, offer to fall in him and do his luck beyond the suburban life Willy has lived: ‘William, when I walked into the jungle, I was 17. When I walked out I was 21. And, by God, I was rich! ‘[ 6 ]For Willy, hence, nature has become a topographic point of lost hope where ‘the grass do n't turn any longer ‘[ 7 ]; it does non belong and nor does he: ‘A victim of both a hardhearted capitalist society and his ain ill-conceived dreams, Willy ‘s eventual self-destruction is presented with tragic dimensions. His beliefs may be misguided, but he stays true to them to the terminal. Although he has neither soc ietal nor rational stature, Willy has self-respect, and he strives to keep this as his life falls apart around him. ‘[ 8 ] Supplanting is besides a major characteristic of Jean Rhys ‘s novel, Wide Sargasso Sea. First published in 1966, it is a prequel to Charlotte Bronte ‘s Jane Eyre, foremost published in 1847. The fresh uses nature as a agency of developing the narration of Rochester ‘s first married woman, Bertha Mason, here known as Antoinette Cosway, a immature adult female who feels herself displaced following the liberation of the slaves who had worked on her household ‘s plantation. ‘The really word â€Å" topographic point † occurs many times in the novel ‘[ 9 ]and Antoinette seeks consolation in what she sees as an Eden garden, her former place, from which she is cast out: ‘A really of import early set piece is Antoinette ‘s description of the garden at Coulibri, where she was a kid, a garden which was likely based on Rhys ‘s memories of her female parent ‘s household estate at Geneva. It marks childhood as taking topographic po int in a damaged Eden. ‘[ 10 ]The description of the garden is therefore really of import to an apprehension of Antoinette and of the manner Rhys uses her connexion with nature to help her character and thematic development: Our garden was big and beautiful as that garden in the Bible – the tree of life grew at that place. But it had gone wild. The waies were overgrown and a odor of dead flowers assorted with the fresh life odor. Underneath the tree ferns, tall as forest tree ferns, the visible radiation was green. Orchids flourished out of range or for some ground non to be touched. One was serpentine looking, another like an octopus with long thin brown tentacles bare of foliages hanging from a distorted root. Twice a twelvemonth the octopus orchid flowered – so non an inch of tentacle showed. It was a bell-shaped mass of white, mauve, deep purples, fantastic to see. The aroma was really sweet and strong. I ne'er went near it.[ 11 ] The genitive pronoun with which this paragraph opens instantly establishes the duality of Antoinette ‘s state of affairs. This is her place, it should experience like hers but it does non. The ‘beauty ‘ she infers has a ambidextrous luxuriance because it has ‘gone wild ‘ , symbolic of a land which has lost control, albeit for a positive ground. The ‘living ‘ and the ‘dead ‘ mix and encroach upon one another, and there is a snake in the garden in the ‘snaky ‘ orchids. Furthermore, the ‘twisted root ‘ implies a deformation of what was meant to be, metaphorically repeating Antoinette ‘s supplanting. In add-on, this is non the lone illustration of topographic points looking resonant of temperament and/or state of affairs: ‘Places are highly alive in this novel: the menacing, exuberant garden at Coulibri, the cryptic bathing pool at Coulibri, sunset by the huts of the plantation workers, the route fr om the small town of Massacre up to Granbois, the sea and sky at sundown from the ajoupa or thatched shelter at Granbois, the bathing pools at Granbois ( the bubbly pool and the nutmeg pool ) the forest where Antoinette ‘s hubby wanders until he is lost, the route to Christophine ‘s place, the trees and bamboos around the house at Granbois. ‘[ 12 ]Here, Antoinette appears at the same time intoxicated and repelled by the ‘sweet and strong ‘ of the garden, which possibly says something about her similarly ambivalent attitude towards those around her and they to her: ‘The image we now have of Rhys and her heroines is that of a inactive, impotent, self-victimized schizotypal personality who, comfy with failure, wields her weakness like a arm — all every bit natural as being female. ‘[ 13 ]The presentation of nature at the ‘honeymoon house ‘ is likewise hard to put, looking to be one thing but really being another, but her form er place is ‘a sacred infinite where Antoinette hugs to herself the secret hidden in Coulibri ‘ .[ 14 ]It is, so, these secrets in isolation, echoed in the descriptions of Antoinette ‘s fatherland that make the representation of nature in Wide Sargasso Sea so clearly an jussive mood of the text: Equally long as Antoinette can retrieve and order the events of her memories into a temporal or causal sequence, make even an semblance of sequence and keep a mensural sense of infinite and clip, so she can keep her life and ego together. Her act of narrative becomes an act of avowal and coherence, a nod to the universe and its conventions, an effort to forestall herself from fade outing. When, in Part Three, Antoinette lies encaged in Thornfield Hall ‘s dark, cold loft, the togss that hold her to the world that the universe perceives as saneness eventually interrupt. These togss are the elements of conventional narrative: additive chronology, sequence, narratorial clarity, distance. She herself admits at this point that ‘time has no significance ‘ ; sequence disintegrates into a confusion of present and past and finally into a dream which narrates her hereafter.[ 15 ] This has been quoted at length because it addresses many of the literary devices that the novelist, as opposed to the dramatist or poet, can utilize to develop a subject. With respect to nature, it is used by Rhys, as suggested above, to make a temporal infinite for Antoinette that is symbolic of the individuality she has lost. The abandon which is infringing upon the Eden of the garden, subsequently to be wholly destroyed, is an illustration of the manner in which the novelist can utilize one strong image to take into another, both being resonant of the yesteryear. Indeed, once more as stated above, the act of stating the narrative creates the character in the head of the reader and the locations in which she is placed are connected to that, as is the temporal disruption which memory green goodss and which is frequently, as with Antoinette, declarative mood of her province of head. The evocation of nature as a turbulent and affectional presence adds to this, with the sea as the ulti mate semiotic of challenge, pandemonium and disruption. Grace Nichols ‘ 2nd aggregation of poetry, The Fat Black Woman ‘s Poems, published in 1984, besides uses nature to arouse a peculiar image. However, as this is poesy, the lingual and literary devices used are really different from either those of the dramatist and/or novelist. ‘Nichols grew up in Guyana ‘[ 16 ]but has made her life and calling in England, ‘she has lived and worked in Britain since 1977 ‘[ 17 ], and this cross-cultural jussive mood is really much evident in her work: ‘her poems often acknowledge the foreigner clime, geographics, and civilization of England ‘s metropoliss ‘[ 18 ]Within The Fat Black Woman ‘s Poems, Nichols seeks to arouse a different perceptual experience of beauty from that which is shown in white Western civilization: ‘Nichols besides deploys the fat black adult female as a powerful challenge to the dictatorship of Western impressions of female beauty ‘[ 19 ]and therefore ‘ engender a new heroine, a adult female who revises the aesthetic of female beauty. ‘[ 20 ]One of the techniques Nichols employs to make this is uniting nature with an facet of the physical ego, as here in ‘Thoughts floating through the fat black adult female ‘s caput while holding a full bubble bath ‘ : Steatopygous sky Steatopygous sea Steatopygous moving ridges Steatopygous me[ 21 ] The unfamiliar word, ‘steatopygous ‘ ( intending holding to the full rounded natess ) is repeated for accent and juxtaposed with images of nature so as to bring forth an emblem of the black adult female as stopping point to nature, her organic structure shaped like the sky, moving ridges and sea. Nichols is authorising black adult females in image by making this as she does by giving the black adult female her ain alone voice: ‘In doing the fat black adult female the speech production topic of many of these verse forms, Nichols signals her refusal to busy the topic ( erectile dysfunction ) place designated for the black adult female by history and to take a firm stand on more complex subjectivenesss. ‘[ 22 ]Nichols is besides concerned that the voice should look realistic and hence the natural images perform yet another map: ‘Like many Afro-Caribbean authors, Nichols infuses her poesy with the religious energy of the tradition of adult females before her , a tradition that has little written record. ‘[ 23 ] In another verse form from the aggregation, ‘Beauty ‘ , this reproduction of a different image of physical entreaty can besides be seen to be connected with nature: Beauty is a fat black adult female walking the Fieldss pressing a breezed hibiscus to her cheek while the Sun lights up her pess Beauty is a fat black adult female siting the moving ridges floating in happy limbo while the sea turns back to embrace her form[ 24 ] Again, the adult female is juxtaposed with nature, supplying a integrity between the character and her milieus which is both actual and metaphorical. Repeat is used one time more by the poet to underscore the connexion between the subject of the aggregation and beauty in abstract. Indeed, the word ‘Beauty ‘ , the merely capitalised word in the verse form, is set entirely on a line, as is ‘hibiscus ‘ , as if to emphasize its importance as an emblem or iconic of what Nichols says is an imperative i.e. that this is what beauty unambiguously is. There is a common embracing between the adult female and nature, she ‘pressing ‘ the ‘hibiscus/to her cheek ‘ and ‘the sea bend [ ing ] back/to hug her form ‘ . It is as if Nichols is proposing that the ‘fat black adult female ‘ who is ‘riding the waves/drifting in happy limbo ‘ is in unison with nature and recognised by it as being so. All of nature, so, like â⠂¬Ëœthe Sun [ that ] lights up her pess ‘ is lauding her and she it. There is no punctuation in the poetries, underscoring the smooth, natural flow of the descriptions and the manner in which they are intended to connote all that is inherently natural. As Nichols writes in ‘The Assertion ‘ , ‘This is my birthright ‘[ 25 ]and therefore the probe of beauty within the verse forms becomes a socio-political jussive mood, excessively. In decision, all three texts – Miller ‘s Death of a Salesman, Rhys ‘s Wide Sargasso Sea and Nichols ‘ The Fat Black Woman ‘s Poems – all use nature as a manner of enlarging upon and more efficaciously showing their cardinal concerns. An of import component of this is the manner in which hapless false belief is used by the writers, i.e. nature reflecting and/or proposing a temper or subject. As the three texts discussed here are from different genres, they of class usage nature in different ways, using different literary devices, as has been shown. However, for each of the writers nature is singularly of import and enriches the single texts immeasurably. In the concluding analysis, hence, it might be suggested, so, that nature itself becomes about a communicative character within each of the really different plants discussed within this essay, as its importance to the creative activity and communicating of each can non be overestimated.

The specification I was given was that the circuit board could be no bigger than 100 x 160mm and could cost no more than  £50. Taking the specification into account I searched for components I would use to construct the circuit making sure the price was under the  £50 limit (the total cost was  £42.99). The second task I undertook was to design a board within the required size (the final size was 89 x 74mm) but I ran into problems with the design because of this there was a total of 20 designs before the board was ready to be manufactured, some of the problems are listed below. SIL Reed relay pins were the wrong size Earth connections were missing LED’s were over-lapping The pins on the 7406 were connected the wrong way round Once the PCB was designed, the board was then manufactured. The manufacturing process can be found in Appendix page 2`. The next stage was to test and populate the board, continuity testing was done by using a multi-meter to check for open and short circuits and then hand soldering all the components in place. The population process took me around 3 hours instead of the 2 hours planned as I had to de-solder my wire links as they were not of an acceptable standard. The final process was to test the finished PCB, this was done by testing the outputs on the board as they all worked first time I had no extra fault finding/debugging to do. Conclusion As the circuit worked first time I proved that I would be capable of undergoing projects like this in the future. The main reason for the circuit working was the amount of time I spent at the design process. This would save companies money in real life, as there would be no waste of materials.

Stereotypes of Native Americans in Film

Stereotypes of Native Americans in Film Introduction Native Americans are the people who lived in the supercontinent of America before the Europeans went to settle there. They are the indigenous people of the continent of America. Some people also call them the American Indians. These people did not welcome the Europeans movement to their continent.Advertising We will write a custom research paper sample on Stereotypes of Native Americans in Film specifically for you for only $16.05 $11/page Learn More Like any other society in the pre-colonial times, the Native Americans faced the Europeans with hostility in their attempt to prevent the whites from settling in their native land.  Their actions and nature made the Europeans develop a negative attitude towards them since they did not give them a chance to control the society. This became the platform for moviemakers in the film industry not only during those times, but also in the present time. It created the atmosphere of stereotypes in films es pecially those from the West.  According to Lippmann, stereotypes are standardized mental pictures that members of a group hold in common and present a simplified opinion, prejudiced attitude and judgements that are not critical (24). Native Americans were simple people who based their culture more on mystery than science. North America had approximately six hundred different indigenous American societies speaking two hundred different languages. The whites treated all these societies as one entity in stereotyping the Native Americans (Barnett 72). The film industry has played an important role in bringing out the perceptions of the Europeans towards the Native Americans. According to Battaille and Silet, Native Americans have appeared in movies/films since the beginning of the industry in 1894 (14). It is important to note that the stereotypes held towards the Native Americans are negative and damaging and this underscores racism and segregation that this minor group has experien ced throughout the history. Stereotyping of the Native Americans was not only by films, but also by other forms of art. The western community also used fiction and literature. However, films/movies earned masses of audience due to its ability to show moving images. The images in the films helped the audience to get a more precise image of the stereotypes than the other forms of art. However, the stereotypes of the Native Americans in films have exhibited a gradual change over the centuries. Films and perpetuation of Native Americans stereotypes There are several reasons why the media, films, stereotyped the Native Americans. The Western Community wanted to confirm their superiority. They viewed the Native Americans as people who had juvenile and unsophisticated minds (Tuska 18). They wanted the American Indians to embrace their civilized way of living-their social values, worldview, social structure as well as their beliefs.Advertising Looking for research paper on history? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, the Native Americans had their own ways of living and did not find it necessary to adapt the ‘civilized’ ways of the Europeans. Stereotyping of the Native Americans was a type of entertainment. It is because the films have the ability to give an audio-visual presentation of events as well as people’s views.   Films and television presentations reach masses of audience. By presenting the stereotypical images of the American Indians in an entertaining manner, the Europeans were certain that the images would create the intended picture to the audiences’ minds. The impact of such films remained strong in most Americans’ minds to the extent of stigmatizing the indigenous Americans. The other major reason for stereotyping the Native Americans is that it was an approach for the white society to justify their stealing of land from the indigenous Americans. They also used stereotyping as a means of perpetuating the myths on how the western society built America. The Western Community used film images to present the Native Americans as savage, drunken, lazy, and heathen as well as people with who lacked family relationships. They portrayed the Native American man as an individual who was very primitive just like an animal (Delloria 3). An example of such a film is the â€Å"Wild West†. It depicts the Native Americans as haters who lack the least sense of morality. In this film, whenever a Native American character appears, he is involved in evil activities such as raping young girls or women, robbing and even killing people maliciously. Most of these films focused on the negative attributes of the Native Americans and the good traits of the western society. For instance, in the film ‘Wild West’, the western cowboys act as the good people who make relentless efforts to rescue the victims of the Native Americansâ€℠¢ acts. From the beginning of the Film industry to the end of the Second World War, all the scenes in films revolved around the negative perceptions that the Europeans had on the Native Americans. In some productions, the Europeans expressed their hatred of the Native Americans. This was evident on the movie, ‘The Searchers’ which centres on a young girl who was taken after the murder of her parents. During the search, one of the western men found one of the natives dead and shot him on both eyes. The shooting of the dead man is an expression of the western’s society hatred on the Native Americans.Advertising We will write a custom research paper sample on Stereotypes of Native Americans in Film specifically for you for only $16.05 $11/page Learn More Other films that perpetuated Native American stereotypes are ‘Duel in Diablo’, ‘Redman and the Child’, ‘Ramona’ and ‘The Battle of Elderberny Gu lch’. In all these films, the directors/producers did not use Native Americans as characters. The stars of horror movies such as Bela Lagos and Lon Chuney represented the ‘savages’. However, there are some few cases where Native Americans appeared in the films to enhance the creation of an appropriate atmosphere. Native Americans who appeared in such movies include Will Rogers, Chief Dan George, Graham Green and Willie Sampson. By 1890, the Western Society had killed most of the Native Americans. Prior to these years most of the film producers had taken their plots. Since the settlement of the whites in America, producers created many films depicting the bad character of the Native Americans. Between 1951 and 1970, for example, western film producers produced approximately eighty-six movies based on stereotype themes (Delloria 4). The aspect that made these films to find an extensive market was the violence that they portrayed. The emotional aspect that the war f ilms bring plays a major role in engaging the audience thus attracting masses to these films.  The stereotypes fall under three categories. Based on time, the Europeans treated the Native Americans as creatures of a particular time-the time when they were devoted to fight for their land. During this time, the whites experienced the savage warrior in the Native Americans’ land. The second category of the stereotyping is that of the negative interpretation of the American culture by the Europeans. The Americans and the western society had very different cultural values. The Europeans attempted to interpret the Native American culture using their own cultural values through these films. It led to the creation of more stereotypes. The European view of the different American society as one identity is the final category of stereotypes. Different individuals as well as societies have different ways of doing things. The Europeans did not put this into consideration leading into th e misconception of the American Indians. Modern day stereotyping of the Native Americans The increased use of films in stereotyping the Native Americans widened the gap between the Native Americans and the Europeans. As a result, the film producers decided to change the theme of most of their movies. The first film that they produced to make the audience sympathise with the Native Americans was the ‘Lone Ranger’ though Tonto, the main character representing the Native Americans was less intelligent.Advertising Looking for research paper on history? Let's see if we can help you! Get your first paper with 15% OFF Learn More It opened a way of improving the image of the Native Americans in films. Another film by Delmer Daves, the ‘Broken Arrow’ treated the Native Americans in a sympathetic way. Tuska said that, â€Å"It is the only movie that asked audiences to take the side of the Indians† (26).  It is the first film to win the Association of American Indian Affairs Award. The other films that played an important role in breaking the stereotypes were, ‘Tell them Willie Boy is here’, ‘Dancers with Wolves’, ‘Little Bigman’ and the ‘Soldier Blue’. The Americans produced these movies between 1949 and 1991. The image of the Native Americans portrayed in films changed gradually. Producers of such movies chose to major in uplifting the status of the Native Americans. The films no longer depicted the Native Americans as savages, primitive and lazy people. On the contrary, they were smart people who saved their country from the exploitati on by the Europeans.  A most recent film that has helped to paint a good picture of the Native Americans is ‘Dr. Quin Medicine Woman’. It is an example that brings out most of the good traits of the Native Americans. For instance, it portrays them as very helpful: Dr. Quin goes to look for a medicine to cure an illness of the whites. When the town people did not have food to hold a thanksgiving feast, the Native Americans gave them food for the occasion. The Native Americans, in this film, are very friendly as compared to previous films that portrayed them as beasts. They are also more intelligent than the white people are. It is evident that with time the Europeans have respectfully perceived the Native Americans.  Education is a factor that has played a major role in eliminating the Native American stereotypes. It made many people understand that the relationship between the Native Americans and the whites was solely human. Education made people to understand the history of the American Indians leaving them with no excuse to condemn their culture. It further explains that any other group of people would have acted just as the Native Americans. Most people now understand that stereotyping was an approach that the Europeans employed to justify the stealing of the Native Americans’ land and exploitation of their resources. With this understanding, the film industry has ceased from using misleading stereotypic films of the Native Americans. As a result, there has been a decline of such movies. In their efforts to restore their dignity and improve their image, the Native Americans have also found their way to the film industry. Unlike in the past, the film producers incorporate Native Americans as stereotypes of the good traits. This has been a major improvement in the industry. Conclusion Stereotypes of Native Americans in films initially portrayed the Americans as the worst people that have ever existed in the entire American history. Th e stereotypes portrayed the American Indians as hostile, vengeful, immoral and savage. These films received great audience within the American territories. However, they exhibited a declining trend at the end of the Second World War. In this period, producers got a new plot for their movies. The first film that portrayed a good image of the Native Americans won the Association of the American Indian Affairs Award. The award played a major role of motivating the film industry producers to work on improving the image of the native Americans though their productions. Consequently, the industry produced more films that boosted the status of the Native Americans. The films changed the image of the American Indians, from the bad I to good. The good Indian was brave, simple, close to nature and friendly to the whites. Modern films and television presentations have embraced productions that portray the Native Americans as good people in their own perspective. The other aspect that has contr ibuted to this achievement is education. It has made large populations understand the history of the Native Americans. Many people know that the Europeans treated the Native Americans with great hostility; therefore justifying the Americans’ reaction. Owing to this, we expect that in future the film industry will continue to present good image of the American Indians.. Barnett, Louise.The Ignoble Savage: American Literary Racism.

Crows, Ravens and Jays - Corvidae - The Animal Encyclopedia

Crows, Ravens and Jays - Corvidae - The Animal Encyclopedia Crows, ravens and jays (Corvidae) are a group of perching birds that also includes jackdaws, rooks, magpies, nutcrackers, choughs and treepies. In total, there are more than 120 species that belong to the crow family. Crows, ravens and jays are medium to large birds. The group includes the largest members of the perching birds. Many crows, ravens and jays have large wingspans. They have a robust body, strong feet and sturdy bills. Their nares (nasal openings) are fringed by bristle-like feathers known as rictal bristles. In temperate areas, most members of the group are partly or entirely black, blue, iridescent blue or iridescent purple. Some species, such as the magpies and jays, are more varied in color. They might have plumage with a mixture of black, white, grey and blue markings. Members of this group of birds are thought to be highly intelligent, not just among birds but among all animals. Crows and rooks have demonstrated tool making abilities while European magpies have exhibited self-awareness in mirror tests. Many members of the crow family establish and protect territories either during the breeding season or throughout the year. When threatened, some corvids can defend their offspring or territories aggressively and are known to attack large animals such as other birds, dogs or cats. Many species of corvids form social groups and hierarchies for foraging and breeding. Many species of corvids have flourished in human environments. But while such species have enjoyed healthy populations, a few corvids have experienced declines. Examples of threatened members of the crow family include the Florida scrub jay, the Mariana crow and the New Zealand raven. Crows and their relatives form strong pair bonds and in some species this association is life-long. In most species, nests are constructed in trees or on rock ledges. Nests are built using twigs, grass and other plant materials. Females lay between 3 and 10 eggs and young fledge after about 10 days. The largest member of the crow family is the common raven which grows to more than 26 inches in length and weighs 3 pounds. The smallest member of the crow family is the dwarf jay which grows to about 8 inches and weighs little more than an ounce. Crows, ravens and jays have a nearly-worldwide distribution. They are absent from only the southern tip of South America and the polar regions. The group is most diverse in tropical regions of Central America, South America, Asia and Europe. Most members of the crow family do not migrate although when food shortages occur, populations do relocate. Classification Animals Chordates Birds Perching Birds Crows, Ravens and Jays The crows, ravens and jays are divided into about a dozen subgroups, some of which include New World jays, grey jays, azure-winged magpies, Holarctic magpies, Stresemanns bushcrow, piapiac, true crows, nutcrackers, Old World jays, Oriental magpies, treepies and choughs. The crow family is thought to have originated in Australia and spread throughout the world. The closest relatives of the crows, ravens and jays are thought to be the birds of paradise and shrikes. There remains considerable ambiguity regarding the exact lineages and their relationships within the crow family. The earliest members of the crow family date back about 17 million years ago to the middle Miocene. Known fossils include Miocorvus, Miocitta, Miopica and Henocitta. Crows, ravens and jays feed a variety of foods including small mammals, birds, invertebrates as well as fruits, seeds and berries. Some members of the crow family feed on insects such as grasshoppers while others feed on carrion.

Business opportunities Essay Example | Topics and Well Written Essays - 250 words

Business opportunities - Essay Example The business should also possess a unique and superior way of doing things. Building an efficient scalable plan requires an entrepreneur to focus on the consumers as the critical component of the business growth. A business that values customers attracts them and enables them to spend considerably. This also ensures sustainability whereby more customers are anticipated in the future than their current numbers. A scalable plan should describe the industry of operation of the business and identify a niche that the competitors cannot fill. Focus on the business’s environment can be especially difficult if the competitors are of the same size or experience the difficulties of monopoly dominance. Once the business has identified the marketing niche, it should apply the necessary strategies that enhance its expansion into a prominent player. Health care scalable plan focuses on strategic performance, project management and process improvement (CeÃŒ line, BeÃŒ rard and Luc, Cassivi 160).

The current and future role of localised charitable organisations in Essay

The current and future role of localised charitable organisations in Birmingham - Essay Example This paper focuses on the current health of the three localised charitable organisations in the city of Birmingham who deliver housing support and care services and how they are responding to the current business climate. It explores their experiences from the historic grant funding arrangements to the current contracting culture. It compares each organisation using a detailed analysis process with emphasis on examining the rational where the qualitative data highlights similarities and disparity. The key research components of the dissertation are: how each organisation has changed financially and whether this has impacted on structure and size; and whether this has seen a change in direction in relation to business planning and strategic management. It also measures how far each organisation has diversified within their service provision in order to remain viable and goes some way in answering whether such diversification is perpetuating a move away from their traditional roots and charitable aims. It also observes and provides comment on how the organisations are planning and preparing for the future using their abilities to assess and respond to the perceived threats and opportunities within an open social care market and what they perceive will be their futures and that of the charitable sector in Birmingham. The dissertation analyses the impact marketisation and business-like approaches being adopted by the three organisations and whether such changes are an inevitable consequence of having to remain competitive and strengthen the sector.

Reaction Time of Firefighters Research Paper Example | Topics and Well Written Essays - 1500 words

Reaction Time of Firefighters - Research Paper Example Similarly, the reaction time of night shift is comparatively higher than that of 10-hours shift (table 3). Thus, the results demonstrate that the firefighters working in 24-hours shift with are more efficient to respond to any emergency call. Further this hypothesis was tested using the anova test in order to see if there was any equality of variance across the shifts in which the firefighters were performing their job. This test also confirmed the assumption previously discussed that the reaction time increased with 24-hours shift as compared to the day shift and night shift (table 4). Thus, the performance level improves with the increase of shift timing. It is imparative to describe that in order to eliminate any wrong conclusion, these tests were recorded separaely in the beginning of shift as well as at the end of the shift.

River Woods Plant Manager Case Study Example | Topics and Well Written Essays - 2250 words

River Woods Plant Manager - Case Study Example In order for the project to be successful, the manager will be needed to come up with strategies to manage the project together with the subordinates and the expected challenges. This will be especially helpful because he will be new, with a new project and current subordinates who have been using functional lines of reporting. In this case there is an introduction of a new plant in a location away from the headquarters. Current personnel will be shifted to work at the location of the new plant and any extra staff will be taken to other branches. The new plant is viewed to be viable in the future and it will have new methods of production, manpower requirement as well as lower cost of production because it will be automated. The new plant is being used to implement a decentralized system of management signaling a move away from the centralized system where there was function line reporting. In the centralized method, marketing was under the vice president, manufacturing and other functions under senior vice president and no plant had a general manager. In the new system the general manager will take charge of personnel and all function save for sales and marketing (Whetten & Cameron, 2007). There are concerns over a shift from line reporting to plant level focus as well as upgrading the current staff to use the new plant. Use of the new plant, setting of procedures, appliance design and production plan are expected to pose a challenge. There are complaints from the current employees over moving to a smaller town who are also dissatisfied with their new roles. These are the same people who will be expected to foster unity of the plant and assist in success of the new plant and the entire company. Issues are expected between managers with regard to power sharing and teaching them on how to exercise their power with the new changes. In an organizational context, personal power of the manager

Critically examine how effective the Single European Act has been in Essay

Critically examine how effective the Single European Act has been in creating a European Internal Market - Essay Example Through a historical overview of the treaties upon which the EU is founded, followed by a discursive analysis of the enlargement process, the creation of joint borders through the Schengen Agreement, and the formulation of a monetary regime whose outcome was he implementation of a single EU monetary unit, the research shall demonstrate that while the SEA contributed to both the deepening and the fortification of the integrative process, it is hardly single-handedly, or even primarily, responsible for the evolution of the EU of 2005. The European Union is a unique example of political economic integration. Even though Paul and De Burca date the creation of the EU to the birth of the Maastricht Treaty in 1993, others have contended this to be erroneous, insisting that the evolutionary process spanned five decades. This argument is forwarded by Molle (2001) and expressed in his contention that evolved from a limited common market with only six member states to a regional political and economic bloc, comprising twenty-five nations, in the span of five decades, the European Union provides political economists and legal scholars with a unique insight into the legal strategies and frameworks requisite for the realization of such an ambitious project. The European Union project, as noted by Molle (2001), was predicated on the assumption that regional political and economic unification could restore European global economic and political power and with this assumption functioning as a prime motivator, legislature and tr eaties among towards the realization of the stated goal, entered the formulation stage I 1948 and the implementation stage in 1952 (Molle, 2001). 1952 witnessed the passage and implementation of the EU’s founding treaty, the Treaty of Paris. At this stage, the European integration process was confined to the creation of the

Animal Experimentation Essay Example for Free

Animal Experimentation Essay Throughout history, animal experimentation has played an important role in leading to new discoveries and human benefit. However, what many people tend to forget are the great numbers of animal subjects that have suffered serious harm during the process of experimentation. Many people are believed to be ignorant or misunderstand the nature of the lives that animals actually live, and are unable to understand the actual laboratory procedures and techniques. Other than the philosophical questions that arise, ethical (moral) questions are the main reason why many animal right activists want it banned in every country. Activists feel that to this day, there should be no good reason why any living thing should be subjected to this cruel punishment and unwanted torture just for serving another being’s needs. Although animal experimentation has been around for centuries, the ethical revival of realization on the moral status of animals began in the 1970’s. This problem was a few among many that had been quietly hidden for years until the 1970’s. Such movements like gaining rights for the oppressed, expressions of antiwar opinions in the U.  S. A, and the women’s liberation movement, accompanied the movement for the ending animal experimentation. The animal rights movement has grown more and more complicated through its use of strategy and has successfully brought the issue of laboratory research to the eyes of the public. All forms of media, magazines, radio, television, newspapers, have increased their exposure of animal right protests over the last several years while giving room for groups to produce their own publications. In these publications, activists constantly make the analogy between the work of abolitionists before the emancipation and the efforts of animal right activists. This analogy of racism and â€Å"speciesism† was brought about by a philosopher named Richard Ryder in 1985 and brings up the issue of research with animal subjects to be emotionally unpredictable for many people. (Sperling Susan – Applied Ethics in Animal Research Introduction pgs 4-6) One of the biggest problems and the main reason why animal experimentation should be banned is the large percentage of birth defects that occur. The difference is that humans may also a longer period of fetal development and be more sensitive to birth defects agents than other species. One example of another problem with animal experimentation are that animals can be given nicotine directly as opposed to being exposed to it as a human would for years. Another would be that stress caused by animal handling, whether it be because of lack food or water, may have adverse effects on pregnancy or its ability to mate with the opposite sex. Also these tests are too insensitive and tend to disregard learning or behavioral problems. Our plain existence can influence the behavior of animals and disturb activities such as feeding, care- giving, and mating conduct. (Cognitive and deep ethnology and the great ape project- page 82-86) There have even been laws that have been recently erected to protect the existence and safety of these animal â€Å"victims†. One law known as Kanjorski’s Law states that any substance (that is tested on an animal) that can harm a fetal embryo in development, can call the validity of the tests into question. Several factors can determine the effects on the results based on the different kind of species that are used during experimentation. The genetic difference between species can affect its ability to defend itself or a difference in the placenta may also affect the animal tests. (Birth Defect Research-Why Animal Experiments Are Not the Answer) In 1986, a German law was passed and was known as the Animal Protection Act. This act forbade experimentation of tobacco products, washing powders, cosmetics, and the testing of weapons on animals. Soon after this law was passed in Germany, many countries started to adopt the law along with new laws such as the ban on LD50 test and the Draize eye irritancy test. Ld50 is a lethal dose that painfully kills nearly 50 percent of the animals that it is injected into, and the Draize test which can cause blindness in rabbits. Places such as the UK define each limit as to having a limit that should not be succeeded, and if done so would be a criminal offense. Every decade, animal experimentation could be looked at in a different light and activists will always be there to defend animal rights. From the 1960’s to the early 1980’s, teens from eleven to seventeen tried to impress judges of science- fair competitions with cruel live animal experiments. This is just one example of how animal experimentation exists everywhere when supervision is missing. It is also about how laws are not enforced to stop such heinous acts of abuse. The usual projects that the students did were, starving animals to death, blinding the animals, mammalian surgery, and the injection of lethal substances. Although, improvements have been made to convince schools to restrict animal testing. Federal laws do not exist. Thus there are no provisions in this area that ban dissection or mistreatment, and the National Association of Biology Teachers are not responsible. However, the amendment made in 1985 to the Animal Welfare Act required a group committee to review how the uses of animals were to be used in the some of the college courses at some but not all. Despite the fact that rats, mice and birds are excluded from the Animal Welfare Act, activist reform groups have just started their mission and are nowhere near the end. (Orleans, Barbara F. Ethnical Themes Governing Animal Experiments) We should make every effort to study separate animals and to learn more about their abilities to feel their torture, psychologically and physically to understand their true feelings. Hopefully in the future, we will no longer have to depend on animals to give us results on safe products. We could also be the ones chained up and experimented on by a higher being in the near future.

Rotating Wall Vessel Bioreactor

Rotating Wall Vessel Bioreactor Abstract Recently there are significant amount of research work undergoing about tissue engineering and bioreactor designing. Therefore, there are so may research paper published around the world. It may use embryonic stem cell, mesenchymal stem cell, tissue graft or other animal spaces tissues or cell for development of human and animal medicine treatment. In that case there should be some ethics and laws to control the usage of the tissue or cell in the medical treatment. Some government organizations and private sector by independently or by joining do some research work about the tissue engineering and bioreactor designing. The cardiovascular system is the major disease problem in the human and animal medicine treatment. In recent decade there are cell and tissue engineering and the bioreactor designing involving treating the cardiovascular disease condition. Researchers may try to develop heart valve, wall and blood vessel etc. Hole in the heart is complex congenital heart diseases, in n ew born babies and leading causes of mortality. The treatment of this kind of the cardiovascular disease only performed surgery correction, the very painful after the surgery at tolerate by baby. When correcting the hole, that must have closed properly otherwise it lead to another problem to the young one, but measurement of the diameter of the hole is very difficult and correction also very difficult. In the recent decade there is stem cell therapy and the tissue engineering has rapidly developed. By using stem cell and tissue culture there are so many researches and development of the treatment about cardiovascular system. Myocardial tissue engineering developed the heart tissue by using the stem cells in three-dimensional matrices of biodegradable polymers scaffold is the innovation of the myocardial constructs and cardiovascular treatment. Introduction The heart is the most important organs in the human body. It transports blood to the organs, tissues, and cells of the body. Blood delivers oxygen and nutrients to every cell and removes the carbon dioxide and waste products excreted by those cells. A Holes in the Heart is an opening in the septum between atria or ventricles of heart, this is congenital condition. 8-10/1000 live born babies has congenital defects in the heart. This condition occurred during the babys heart does not develop inside the womb; no specific cause for this condition, but some increase risk of being born. If mother had German measles or toxoplasmosis during pregnancy, or if she has diabetes, or if someone else in her family was born with a heart complaint. A hole in the heart may be noticed in the first few months of life or even before the baby is born, sometimes a hole is not found until a person is much older. This often happens when the hole is between the upper chambers of heart. It may notice person a re feeling a bit short of breath and dont know why. But sometimes there are no complaints at all. Because of the hole, the flow of blood through the heart is abnormal. This makes noises in the heart, so a doctor can find the hole by listening to the heart with a stethoscope. If the doctor hears a murmur, this tells the doctor there could be a hole. If the doctor thinks there is a hole, person will have an echocardiogram ultrasound test of heart. Sometimes the hole isnt found until a person is much older when they notice they are feeling tired and breathless and cant find a reason for it. Some holes are so small that they cause no problem and are left alone. Some holes in small babies may close by themselves: if the cardiologist thinks this is likely, he will not close it immediately, but wait for some time to see if it has closed by itself, by repeating an echo. Other holes must be closed, either because they are already a problem, or because they will cause a problem in the future .   There are three different types: Atrial Septal Defect (ASD): this is a hole in the wall between the atria (interatrial septum). This causes more blood to flow to the lungs and may not have any symptoms; the excess flow can damage the lungs. If the hole is small, and doesnt affect the function of heart, theres no need to fix it. Ventricular Septal Defect (VSD): this is a hole in the interventricular septum or wall between two lower chambers (RV and LV). If its large, can change the mechanics in heart. This makes the heart work harder than it should and can enlarge it. If the hole is small, and doesnt affect the function of heart, theres no need to fix it. Atrioventricular Septal Defect: this is a large hole in the middle of heart between the atria and ventricles. Some people with this condition only have one valve between the atria and ventricles instead of two. This defect can also damage the lungs by allowing too much blood to flow to the lungs. Although this condition is uncommon, t can be found in babies born with Downs syndrome. VSDs are the commonest lesion about 25-30% of all congenital heart defects whereas ASD are about 5-8% of them. Another point to remember is that all of us are born with small ASD. However, VSD is never found in normal heart. The only treatment available  was surgical closure. Though the ultimate outcome was good, these children had to inevitably suffer the pain, scar and long hospital stay. There are two ways to do this. The first way is via an operation called catheterisation. This is when a cardiologist puts a tube into leg that goes up towards heart.   Then put a device through that tube so that it fits into the hole. When its in the right place, the device opens like a little umbrella, and blocks the hole. The device stays inside forever. This is not possible, because of the size, shape or position of the hole. In these more complicated situations, a surgeon will perform an operation where he puts a patch over the hole directly. If holes have between the two pump chambers of the heart that stay open, will need antibiotic treatment at certain times. This might be before having other operations or serious treatment at the dentist.  Most patients who have ASD/VSD corrections go on to lead perfectly normal lives. Person will be followed-up for a short period, but if everythings OK after a year, wont need to worry about it ever again. It also doesnt increase the chances of having any other heart-related issues in the future but should take regular exercise and aim for a healthy diet. After correction of the hole in the heart there are low risk for structural degeneration, thrombo-embolism and endocarditis and growth potential for paediatric patient. From 1970s onwards, a group of cardiologists started thinking differently. They experimented on animals by creating holes in their hearts and then tried closing them without surgery. Gradually they replicated the whole procedure on humans. For the last twenty years, nonsurgical closure or device closure has bee n the normal. Adult life heart muscle cells do not proliferate, if there is damage or injuries happened to the heart, functional tissue try to form the non-functional scar tissue. In 1996, 98 Klug et al. Suggest that development of human Embryonic stem cell derived cardiomyocytes help for therapy of cardiac disease. There are some experiments done by using stem cells. Stem cells are the cell ability for self-renewal and the potential for differentiating into mature cell types. The embryonic stem cells can give rise to almost every mature cell type, while adult stem cells are classified as restricted to differentiation into only few types of mature cells. The mesenchymal stem cell can only differentiate to one specific mature cell type, are referred to as precursor cells. First clinical applications of stem cells for cardiac regeneration comprised cell transplantation trials. These trials were less successful than promising preclinical studies; these efforts initiated intense research activities providing new insight into the mechanisms of tissue growth and differentiation. Cardiac tissue engineering is focused on three different organ subunits: the myocardium, valves, and vessels. These three compounds of the heart can already be replaced by artificial or biological transplant constructs with th eir respective limitations, like assist devices, commercial heart valves, autologous coronary bypasses, etc. When developing the heart tissue must consider produced cardiomyocytes, vascular endothelial cell and the smooth muscles cell. Engineering these tissues must compete with the durability, efficiency and safety of existing substitutes and be affordable at the same time. Tissue engineering is the development of biological substitutes that restore, maintain, or improve tissue function or a whole organ, includes an in vitro. During designing of bioreactor, physiochemical environment maintain is very impotent, that will help to kept high quality of the stem cells and high degree of reproducibility of the cells. But must make sure cell culture has developed under sterile environment and sufficient nutrition and waste product exchange throughout the medium and clean and maintain the medium. After that, design some mechanical and hydrodynamic force to compression or expansion of the developing tissue, like shear stress to the tissue. Then maintain steady flow of media in pulsatile manner and reduce the excessive turbulence in the fluid flow rate. Other than that, must provide the low volume capacity for effective use for growth factors and medium, also select the fabricate material compatible with the heart tissue or stem cell. The bioreactor designing for heart tissue development must determine some specific design and functional requirement. Both biomechanical and biochemical factors affect the growth of t he cell therefore essential to create some control mechanism by stimulate the physiological environment for heart cell growth, like pulsatile forces, pressure, flow rate, compression, expansion, shear stress, frequency, stroke rate and stroke volume. Other than that, when creating heart tissue must consider cardiac flow rate and pressure. When consider the design the bioreactor, there are nutrition, oxygen, carbon dioxide, waste product, pH, temperature and humidity are main important biochemical controls affect the growth of the cell. There than the flow rate, volume, shear stress, pressure, resistance and compliance like biomechanical controls also involved in the cell growth. Therefore, specific bioreactors are need for the growth of the stem cell. Because inside the body, cells are always stimulated by mechanical, electrical and chemical signals, these influencing their behaviour. In fact, biological tissues adapt their structure and composition to surrounding specific and funct ional demands. By putting cells alone or only in contact with materials in culture medium is not enough to obtain a functional tissue. In vivo, the heart valves are subject to a unique combination of mechanical stimuli, including flexure, shear stress, and tension (Vesely and Boughner 1989). In growth of the embryonic stem cells require temperature, partial pressure of oxygen, partial pressure of carbon dioxide, pH, and shear force and biochemical conditions of their micro- and macro-environment. Then try to find homogeneous and constant conditions for micro- and macro-environment for the entire cells population. By uneven cell distribution, lack of nutrition and oxygen and insufficient extracellular matrix production cause some limitation to bioreactor scaffold in stem cell culture. Therefore, get rid of those must make to stem cell onto polymers, which will increase the mechanical strength of the heart tissue construction and develop subsequent tissue formation. To develop a bioreactor to provide cyclic flexural stimulation, to demonstrate the operation of the bioreactor and sterility maintenance and to evaluate the effects of unidirectional flexure on the effective stiffness of bioresorbable polymeric scaffolds which have been used extensively in the tissue engineering of the heart tissue. Therefore, must design the devices for closed controlled environment in which biological and/or biochemical processes are developed maintained pH, temperature, pressure, nutrient supply and waste removal, with high degree of reproducibility of the heart valve. Therefore, bioreactors are particularly crucial for the regeneration of complex 3D tissues. The bioreactor was designed using 3D software. The structural element of the device was machined from polysulfone; chosen for its excellent thermal and chemical stability; and abrasion-resistant acrylic; which provides good optical transparency. Culture medium was Dulbeccos Modified Eagles Medium with 4.5 g/L glucose and L-glutamine supplemented with 10% fetal bovine serum. Antibiotics were excluded to assess the intrinsic ability of the bioreactor to maintain sterility. When developing scaffold use the degradable material and permanent materials as in artificial implants and in use of cells. Then preparing scaffold must test in vitro and in vivo how they hypotheses of scaffold and cell interaction, scaffold effect on tissue growth and 3D environment effect on stem cell differentiation. Scaffold materials consisted of a non-woven mesh of polyglycolic acid(PGA) fibers dip-coated with poly-4-hydroxybutyrate (P4HB), and a non- woven, 50:50 blend, mesh of PGA and poly-L-lactic acid (PLLA) fibers dip-coated with P4HB. The PGA and PGA/PLLa scaffold had an approximate fiber diameter of 0.012-0.015 mm and density of 69mg/ml. Rectangular scaffold sample were cut to size (approximately 257.5x2mm) and dipped briefly into a solution of P4HB in tetrahydrofuran (1% wt/vol), resulting in a P4HB coatin g following solvent evaporation. P4HB is a bioresorbable thermoplastic that allows for scaffold to be moulded into any shape. Scaffold were cold gas sterilized with ethylene oxide prior to use. The use of bioreactors, chambers which provide the flow of nutrient media for the development and culture of heart valves construct, to provide an environment which as closely as possible mimics the natural in vivo conditions. These bioreactors have been designed for pulsatile flow, driven by a pulsatile pump, which leads to the exertion of only a positive pressure. This is not the case in vivo, as during the cardiac cycle the positive pressure exerted by fluid force is slightly counterbalanced by a little vacuum. Stem cells grow in vitro under bioreactor conditions must provide the nutrient and they produced the nitrogen contain waste product, but they sensitive to the nitrogenated waste product. This will be varying with the tissue and that will change the shear stresses effecting on the tissue. The oxygen pressure is maintained at set constant value with calculated volume of solution added every time to the medium. Other way round maintained the carbon dioxide pressure at set cons tant value with calculated volume of waste product removed from the medium. Oxygen is most important nutrients for cells in all aerobic metabolic cycles. It is the limiting nutrient in successful tissue growth in vitro, sufficient amounts of oxygen to the surface of the cells mainly because of the poor solubility of oxygen in culture media. In that case hypo-oxygen or hyper-oxygen stresses will be concern the stem cell culture causes of programmed cell death or apoptosis. Therefore, adjust the stem cell for the anaerobic cell metabolism with low oxygen tension (40 mmHg) and low pH or for aerobic cell metabolism with higher oxygen tension (80mmHg) and high pH. Then living tissue is sensitive to pH changes in the medium, during maintain of the oxygen level must maintain the pH also. Other than that glucose and lactate are providing to cell metabolic process. Therefore, they act as the indicator for cells activity. In the bioreactor environment stem cell proliferates and increased the mass that leads the limitation of the final size of the tissue grow. Other than that, there are spaces to pass oxygen and nutrient throughout the scaffold otherwise this also leads to limitation of the tissue growth. Therefore, bioreactor must design to proper diffusion of oxygen and the nutrient and mass proliferation; cell will survive and proliferate within 150-200 µm distance. Shear stress will affect the tissue culture growth, most of the stem cell responds to it. They are proliferating according the orientation of the flow direction. In that case stem cell can aggregates by using higher shear stress that can be used for tissue function and viability. If design the rotating bioreactor that can decrease the shear stress and avoids the contact between the cells and the wall of the bioreactor, chamber must permanently rotate with one direction and control to forming uniformed growth of the tissue. But if design the non-rotating bioreactor then must create the specific mechanical stress applied on the cell culture, by perfusion solution can passed through the cell tissues by flow through the culture chamber. Some experiments were demonstrated that the shears stress 0.1 dyn/cm2 was ideal for stem cell to growth. If that exceeds the shears stress 1 dyn/cm2 were damaged the cells and the shears 0.01 dyn/cm2 were insufficient to promote the growth.   Bioreactors have developed functional heart tissue in vitro environment over specific biochemical and physical signals known to regulate cell differentiation, by improving the formation of the heart tissue by proving uniformed mixing pattern, transported the nutrient to enhance the cell growth and hydrodynamic or mechanical stimulation for stem cell to develop. Simple static flasks or a magnetically stirred flask is not suitable environment for 3-dimensional heart tissue scaffolds to develop. To develop the lowest possible homogeneous cell number for heart tissue, must grow the cell with uniform and efficient of porous scaffolds. When compare the cells seeding into mixed petri dishes yield with the static loading of the cell into the scaffolds has thicker constructs and more spatially uniformed distribution of cells. By seeding in rotating vessels or mixed flask must maintain a uniformed suspension of isolated cells and provide a relative velocity between cells and the scaffold durin g seeding. Dynamic seeding using mixed flasks will show to achieve seeding efficiencies approaching 100% but led to cell densities higher at the scaffold periphery. Therefore, when design bioreactor; must provide the scaffold perfusion with a cell suspension in alternate directions, which lead to the more homogenous seeding on a variety of scaffold with potential yield. Once the cells are associated with the scaffold, cell-polymer constructs can be cultured in bioreactors applying specific regimes of fluid flow. Selecting rotation wall vessels bioreactor The bioreactors are used for proliferation of cells on a small or large scale, to generate 3D tissue constructs, a certain process must occur. That case the cells are proliferated in a bioreactor to provide the quantity of cells needed. The cell loses their specialized characteristics during the process of proliferation is the problem. Therefore, microcarrier culture used for improves cell expansion significantly and that mixed the bioreactor system well. After the cell proliferation they must associate with enhanced heart tissue formation. In above process cells must receive proper nutrition and a stable environment. There for controlled the temperature, optimum pH, sufficient substrate, water, salts, vitamins, and oxygen. The Rotating-wall vessel culture is the best bioreactor for culturing constructs stained intensely, and homogeneously for scaffold for their cross-sectional area. Inside the bioreactor a dynamic flow generated by a rotating fluid environment is an alternative and efficient way to reduce diffusion limitations of nutrients and wastes. The rotation produced the low level of the shear stress to the cells, creating mechanical stimulation. Other than that, there are other mechanical forces that affect the cells during growth, like mechanical compression, hydrodynamic pressure, and fluid flow. They will affect the magnitude, frequency, and duty of the bioreactor cycle.   To control the free-falling state adjusted the rotation speed, it protects the fragile tissue by decreasing the shear stress and avoiding the contact between cells and the walls of the bioreactor. During 1990s NASA scientist did some research about the microgravity involved in to the cell tissue of the mammals. They used the closed tubular cylinder forms the systems cell culture chamber, which filled with a liquid medium where the cell grows on micron-size beads. The chamber has rotated along the horizontal axis; in that case they allowed the cell to develop in an environment like the free fall of microgravity. They supply oxygen and nutrition through a porous wall in the chamber, as same way they removed the waste product and the carbon dioxide. The rotating wall vessel bioreactor is providing the conditions of weightlessness for microbes by growing them inside of a slowly rotating liquid-filled chamber. The process of the rotation liquid has counteracted with slow sedimentation of the cell by creating a constant free fall of the cells through the culture medium. While rotation cell gets a slight sheer stress from liquid, lead to avoid the flattened on the bottom of the container. The scientist used the clear shell for allowed to check growth and cylindrical filter holds on the centre for supply the oxygen and nutrition and removed the carbon dioxide and waste products. And, they insure the fluid rotation without shear stress would leads to destroy the cells. They noticed rotation vessels did not cancelled the gravity, but that maintain the cells in continual free fall environment inside the shell.   Bioreactors for the application of physical forces to engineered cartilage tissues. In the rotating wall vessel system (A), the rotational speed is adjusted so that the drag force of the medium (Fd) is balanced by the centrifugal (Fc) and gravitational (Fg) forces. The constructs are thus maintained in a tumble-slide regime and the resulting dynamic laminar flow enhances the production and accumulation of cartilaginous extracellular matrix. Specific culture chambers (B) have been developed for the application of direct deformation to engineered constructs. Chambers include wells to allocate tissue constructs (I), a magnetic bar for medium stirring (II), an inlet/outlet port for medium change (III), a cover lid to maintain sterility (IV), and micrometer screws to accurately establish the contact position between the plungers and each specimen (V). The cell seeding is effects of shaking speed and initial cell concentration in suspension on cell culture medium, therefore cell seeding must do in efficiency. In that case initial seeding density and cell distribution within the scaffolds must understand. Initially cell concentration is low, in that time seeding efficiency and initial density will decreased with increasing shaking speed. But high initial cell concentration that will reverse the result. All the different cell concentration uniformity of the cell distribution decreased with increased shaking speed. But under the same shaking intensity were observed with on significant differences in uniformity between cells with different initial concentration. In vitro the tissue engineering of heart tissue structures is to develop combined cell seeding and perfusion system. Cell seeding is consisting of whole system, that incorporated into the perfusion system and air-driven respirator pump connected to the bioreactor. Therefore, ce ll culture medium is closed-loop system that will continuously circulate. Therefore, scientist developed a cell seeding device for static and dynamic seeding of vascular cells onto a polymeric vascular scaffold and a closed-loop perfuse bioreactor for long term vascular conditioning. By using cell seeding chamber can be easily connected to the bioreactor, which have combines continuous pulsatile perfusion and mechanical stimulation to the tissue -engineered conduct. In that scientist adjust the stroke volume, the stroke rate, and inspiration/ expiration time of the ventilator allow various pulstile flows and different levels of pressure. Discussion When selecting of the scaffold consider the biocompatibility, reproducibility, biodegradability, ability to be processed to complex shapes, ability to support cell growth and proliferation and mechanical properties of materials. Other than that, scaffolds must have similar electrical and functional activity with create systolic force. The limited availability of the incubator space; the place where the multiple bioreactors place, in this space multiple bioreactors must be places. Development of the stem cell is temperature depended process, any cells grow at body temperature in optimal level therefore temperature must maintain in that level as possible. The bioreactor design must set the temperature parameter to monitor the temperature. If inside temperature changes by increased or decreased then that must alarm on, then it can adjust manually. Sterility is very important throughout the development of the heart tissue. We used flask and glass vessels with threaded fitting, which is cheap and proved to maintain perfect sterility. To reduce the risk of contamination, make sure all connections before sterilisation and sterilize bottles with correction solutions connected to the vessel, by using either alcohol or stem. The tubing can be placed into the pump head easily after the sterilization. Because contamination of the medium lead to the growth of the heart tissue. Therefore, bioreactor must develop as a semi-closed system. Maintain the small cell culture medium all the time, easy replace the balance amount of the cell culture medium for requirement created by cell seeded as soon as possible. If require in addition to that easy seeding of the additional cells. Maintain the oxygen level in the medium is very essential; therefore, reassure the amount of the oxygen in the medium is enough for the development of the stem cells. When we maintain the pH level in the medium that passively adjust oxygen level in the medium, by enrich the medium with CO2 level up to 5%. The biocompatible substances must use when the designing process of the bioreactor, those substance will not kill the stem cell during the tissue growth. There are many analytic parameters, those must monitor regularly with some sensory methods to alarm if there are any changes occur in the media and correct it manually. Any design bioreactor can have ability to experiment several times with longer period. If there are any alternations, like chan ge the cell culture medium with ingredients needed or changer scaffold materials change those and can perform the process easily. By using roller pump can sucks the cell culture medium from the bioreactor, which leads to stress of the scaffold. This help to stem cell growth towards the heart tissue. This bioreactor must use inside the hospital, for treat each of the hole in the heart patient therefore this must produce low cost heart tissue for the patient. Other than that, there should be very low laboratory involvement and convince for patient and the surgeon. When using this kind of tissue engineering think some social highlight that affect the both quality and quantity of the life. Some religious background this technology is some bad for the life, ethical concern there are some extent to do those kinds of experiment. But medical point of view this is the good solution for treatment of the patient without suffering. In that case be careful of handling with stem cell and other, that will lead to caused critical threat to handler. Conclusions The developed bioreactor has set sterility at least week, with working tool for conducting experiments regarding heart tissue growth. The growth of the heart tissue helps to develop entire heart, which can helpful to many heart diseases. Nutrition concentration must keep in mind when performing the bioreactor process. When the time of the replacing the medium nutrition concentration must maintain, also try to minimize the number of time replacement the medium.
