Exercise metabolism - Research Paper Example These studies give an insight on how nutrition affects exercise performance and metabolism. They have different results and findings. However, all of them are geared towards understanding the connection between nutrition and exercise. Nutrients included in these studies include both artificial and natural nutrients. The paper also ensures gender balance because exercise metabolism and performance is different between men and women. Hence, it looks at findings of research done on women. Human beings have different capabilities to exercise. The capability of a human being to exercise is dependent on the biological ability of his or her body to change chemical energy in the skeletal muscle to mechanical energy. Adenosine triphosphate is the chief chemical energy source in skeletal muscles. During exercise, it is characteristic of ATP storage to be depleted fast if it is not quickly replenished. This is mainly caused by the increased demand for ATP resulting from exercise. In many scenarios, when exercising, ATP need and availability are exactly balanced. AT storage is also upheld. Hence, ATP providers in contracting skeletal muscles which are known as metabolic pathways quickly react to the high demand for ATP. What determines ATP demand? ATP demand is determined by the contraction rate of skeletal muscles and the power yield during exercise. Metabolic pathways are described by the enzymes that digest ATP in an exercise session. These enzymes include ATPase, potassiu m transport, and calcium transport ATPase, and actomyosin ATPase. These enzymes are related to the contraction – relaxation cycle (Hargreaves & Lawarence, 1). Homeostasis is key for the proper functioning of the human body, be it during exercise or at rest. Thus, ATP consumption must equal ATP use for homeostasis to be maintained. Diet is a paramount manipulator of the skeletal muscle utilization of ATP when exercising and recovering

Theme of Love in Act 1 Romeo and Juliet Essay Example for Free

Theme of Love in Act 1 Romeo and Juliet Essay â€Å"A pair of star-cross’d lovers take their life† : by using these words in his Prologue and by describing Romeo and Juliet as being â€Å"star-cross’d† Shakespeare is alluding to destiny, the inevitability of the two characters’ paths crossing each other and suggests that the outcome is going to be fatal. The Prologue is written in sonnet form, a form of poetry which is usually used for love and by doing this Shakespeare is suggesting to his audience that that the play is concerned with love as well as tragedy: it brings a sense of heroism to the play and makes Romeo and Juliet the eponymous heroes that every play needs. Shakespeare shows their determination to be together despite the fact their stars are crossed rather than aligned: in the days of Shakespeare it was believed that the positions of the stars ruled over people’s fates and there was nothing they could do to fight it. Shakespeare does not begin the play with the theme of love but rather the theme of hate â€Å"draw thy tool, here comes of the house of Montague’s†. The quote spoken by Gregory a servant of the house Capulet, is telling us how strongly he feels he must support the Capulet’s by hating the Montague servants. Gregory is a servant he has no reason to hate the Montague’s or even hurt them yet he still has anger towards them for no purpose other than they are his master’s enemies. Shakespeare does this, he starts the play with hatred, he embeds this violence and anger into the play between all these people just to show and help the audience understand what really goes on behind the scenes of love. Romeo and Juliet may be in love but Shakespeare tells us their friends, families and relations have an â€Å"ancient grudge† which breaks to â€Å"new mutiny†. The conflict of these two families only reinforces the aspects of love that we see; it tells the audience that if Romeo and Juliet are willing to ignore their families feud despite the consequences that they both would suffer theirs, must be true love and that is why Shakespeare starts off the play with the intertwining of love and hate. The first time Romeo is introduced in the play it is by Lady Montague who inquires of Benvolio (Romeo’s friend) about her son, â€Å"O where is Romeo? Saw you him today?† Shakespeare used these two short sentences to help the audience see the worry of a caring and loving mother, a perfect example of parental love. Shakespeare wants the audience to see Romeo’s parents are very â€Å"hands on† and involved in his life even knowing when he’s upset. Lord Montague tells us that when the sun, â€Å"begin to draw† Romeo â€Å"begin to draw the shady curtains from Aurora’s bed, away from light steals home my heavy son†. Aurora is the Greek god of dawn and Lord Montague is using classical allusion to elevate the idea that Romeo is so miserable he is shutting out the light and is â€Å"heavy† which means sad and depressed. The fact that Lord and Lady Montague are even aware of Romeo’s state shows just how openly they love him and shows their true parental love. Juliet’s parents, Lord and Lady Capulet, have a different approach to parental love and find it harder to express their love for Juliet. Lord Capulet is protective of his only remaining child â€Å"The hopeful lady of my earth† was how he described Juliet, Shakespeare shows a big contrast between Juliet’s parents behaviour by showing Lord Capulet’s open declaration of love for his daughter yet Lady Capulet cannot even speak to Juliet alone, she wants to speak to her daughter about the personal subject of marriage and sends the nurse away â€Å"Nurse give leave a while, We must talk in secret.† But then she says â€Å"Nurse come back again, I have remember’d me†; Lady Capulet needs the help of the Nurse to speak to Juliet: it seems as though she is afraid of her own daughter and wants the Nurse in with her to talk about this sensitive subject. The last type of â€Å"parental† love which Shakespeare explores is the love between Juliet and her Nurse. We feel that the Nurse is more of a mother to Juliet and loves her more than her real mother. On line 62 the nurse says, â€Å"And I might live to see thee married once, I have my wish† she is saying if she could live to see Juliet married even once that’s all she would need to make her happy in life: the quote shows the closeness the Nurse feels for Juliet; she feels as if she were her own daughter and seems to love her as much as if she were. The theme of love continues and it seems as if Shakespeare is mocking Romeo for when Romeo sees Juliet he says, â€Å"Did my heart love till now? Forswear it sight! For I ne’er saw true beauty till this night† Romeo is saying he has never known true love till this moment when, in fact only moments before he was infatuated with Rosaline and was convinced he was heartbroken because Rosaline didn’t love him: his language was completely overdramatic and full of misery when talking about his love for Rosaline, â€Å"this love feel I that feel no love in this.† I think by changing Romeo’s views of love (dramatically) when he sees Juliet from the negative response to Rosaline’s reaction to a positive one to Juliet’s. Shakespeare shows us two different types of love: one between Romeo and Rosaline and the other between Romeo and Juliet. Through this he manages to show that Romeo is so young and naive not knowing the true meaning of love until he meets Juliet: he is just using words and feelings he thinks means he’s in love. The once â€Å"love sick† young man seems to fall in love with Juliet very quickly. He says, â€Å"this love feel I that feel no love in this† which is an oxymoron to show how miserable Romeo is about his unrequited love; he feels he can’t be happy because Rosaline doesn’t love him. However, when Romeo sees Juliet his thoughts and state of mind become much happier: his love for Rosaline is forgotten and his language is very dramatic. His love for Rosaline was purely superficial; proof of this is in line 209-10 â€Å"O she is rich in beauty only poor that when she dies, with her beauty dies her store† whilst expressing his love for Rosaline to Benvolio: but all Romeo seems to actually be expressing is his love of her beauty not her heart or her as a person. In the lines I mentioned previously â€Å"the shady curtains from Aurora’s bed away from light steals home my heavy son† said by Romeo’s father about his son; Shakespeare uses light in a negative way here to show Romeo is upset and doesn’t even want to see th e sun but wants only to shut himself up in his bedroom and wallow in his misery, but when he sees Juliet he uses images of light which makes his love for Juliet more real. Shakespeare also uses classical illusion when talking of Romeo’s unrequited love for Rosaline to elevate how unhappy he is but when talking of his love for Juliet he uses religious imagery to show how happy he is with this love. It is hard for Juliet to know what â€Å"true love† is: when her mother Lady Capulet, and her Nurse propose to her the idea of marrying Paris she says â€Å"it is an honour that I dream not of.† This shows us how completely young and innocent she really is. Shakespeare is telling the audience of Juliet’s youth and reminding them how before Romeo, she had never even thought of being in love. Shakespeare continues the theme of Juliet’s feelings by allowing her to respond to her mother’s question, â€Å"how stands your dispositions to be married?† saying, â€Å"I’ll look to like, if looking liking move.† Here we see the respectable, dutiful child who wants to please her parents. She continues saying â€Å"your consent gives strength to make it fly† agreeing that if her mother approves, she will oblige her mother’s will and do what her mother wishes. In act 1 scene 2 we see a different kind of love, the love parents feel their children should have: the kind of love Paris has for Juliet. This is a contractual type of love. Paris’s love for Juliet is more of a contractual love not true type of love: he sees Juliet the way a woman sees a sparkly diamond; as an object of his affection, something to be desired. Juliet is the diamond to Paris, a step higher in society, a boost to his career and most importantly would be suitable to be the bearer of his future children. Juliet is from a respectable home with high social standing and a powerful father, and Paris is handsome a suitable match for her. The contract of their marriage would be simple. Paris would provide and Juliet would be a dutiful wife but, what Shakespeare tells the audience is that the contract is actually between Paris and Lord Capulet since Juliet is owned by her father until she is married. â€Å"O she doth teach the torches to burn bright† When Romeo first sees Juliet Shakespeare uses light in a positive way to express Romeo’s love for Juliet. Shakespeare delays the inevitable meeting of Romeo and Juliet for five scenes to build tension for the audience. Romeo and Juliet’s love is not just about emotions; Shakespeare also wanted it to be about lust and passion but not just about that and so when they finally meet and they finally kiss Shakespeare uses religious imagery and allusions to elevate their love; for example on line 98-99 Juliet, using gentle poetic language, says â€Å"Saints have hands that pilgrims’ hands do touch, and palm to palm is holy palmers’ kiss.† Shakespeare is not only elevating the kiss but also Juliet’s character by showing the importance of religion to her and how she feels her for Romeo is as strong as her love of religion. At the beginning of my essay I talked about fate; I talked about Romeo and Juliet’s fate being â€Å"cross’d in the stars† and I believe that, and I think Shakespeare believed it too which is why he put it in his play: but I also believe their love was true and pure despite their age and obvious immaturity and different ideas of love. Nothing is worth having if you don’t have to fight for it and Romeo and Juliet fought; they fought the odds, they fought their birth-right and because of this Shakespeare allows us to see the problems attached to pure love.

Negative Aspects of Cosmetic Surgery Essay -- essays research papers

Cosmetic Surgery - Worth the Risk? In today's society the picture of beauty is a thin super model with the body of a goddess posted on billboards all around the world. Children grow up playing with Barbie dolls with the body measurements of would be 90,60,90. Because of these pictures and other figures of beauties projected all over, a person is convinced to believe that to be beautiful and happy, one must look like these images. To most, the easiest way to achieve this is my having cosmetic surgery performed. With the change of times, has also come the advancement of medical procedures, yet how safe can a person be who is having cosmetic surgery performed on their body. No matter how good the technological advancements, there is always the risk of not only the surgery resulting being unwanted but in some cases even death. Society today has brain washed not only today's women, but also the men to believe that in order for a person to look beautiful they must look like the images seen on television, in movies and on the cover of magazines. These images portray grotesquely thin women and muscular men with the famous six-pack abs. The Hollywood figures that are so famous for their looks and bodies also encourage the belief that thin is beautiful. These images are plastered all over billboards, television shows and commercials and magazine advertisements. With all these visions of beauty seen everywhere in a person's every day life, a person feels compelled to look just like those images. Busy lifestyles of many people keep most of exercising daily in order to receive the fit and trim bodies to look beautiful. This then leads many to resort to cosmetic surgery. However, this can be a dangerous choice. Many fatalities have been... ...ons of tomorrow will also be more likely to have more problems as a result of low self-esteem and poor body image. We should not only cut back on the use of cosmetic surgery for safety reasons but also because it is destroying the simple beauty of a person being who they are. The American society will change its view of people in the years to come. Generations to come will grow up feeling that they are being judged on not who they are as a person, but how they look. If they don't look like the super model they have come to believe as perfect beauty, then they will not believe in themselves, causing psychological problems. People considering plastic surgery should be informed of all the risks. They should not be concerned with trying to live up to society's standards and by the price of the operations. They should most be concerned with the real price, their lives.

Murder in missouri: celia’s story

Slavery in America is one of the most intriguing yet controversial episodes in modern history.   Essentially an economic system, its tentacles reached north, south, east, and west.  The culture of slavery, particularly as it developed in the south, was a complex web of social and labor arrangements ranging from gang to task labor, skilled and unskilled workers, field and domestic servants.   Perpetual servitude found legitimacy in the construction of local and state laws designed to undermine the ability of black men, women, and their children to negotiate the conditions of labor and leisure.Although ubiquitous, the character of slavery was unique to each region and the extent of its acceptance determined by local politics and profitability.In the north, where the soil was unsuitable for an agricultural based economy, the factory system developed allowing for the rapid conversion of southern grown raw materials to finished goods.   In the south the plantation system emerged d ue, in large part, to the richness of the soil, numerous waterways, and the widespread of slave laborers both domestic and imported.In the west, where virgin land was most plentiful during the early nineteenth-century, young men like Robert Newsom left the depleted regions of Virginia, oftentimes with their families and slaves, to seek fortune and a better life.It was this â€Å"promise and its fulfillment,† argues Melton A. McLaurin in his true story, Celia, A Slave, that inspired people like Newsom to emigrate to Missouri. [1]   Ã‚  A decisive region in pro and anti-slavery debates, the Missouri Compromise of 1821 insured that there would be slavery in the old Louisiana Territory.   By 1850 Newsom was well respected and considered â€Å"comfortably well off.† [2]In antebellum Missouri, plantations were more the exception than the rule as the economic profitability determined the number of slaves owned by a small farmer.   Still slaves were considered property a nd enslaved women were always subject to the sexual advances of the master.These coerced and morally questionable encounters oftentimes produced children who were the object of the mistress’s hate and a reminder of her husband’s promiscuity.   Ã‚  Enslaved women in Callaway County, Missouri, much like those in other slaveholding regions, were without legal or community protection and, all too often, their suppressed anger erupted in violence and, in some cases, the brutal murder of their master and sexual abuser.[3]Consider the case of Celia, a slave.   Celia was purchased by Robert Newsom when she just fourteen years old.     Convinced that she should be his continuous sex partner and not simply a cook, he raped her on the return trip to Callaway County.   After repeated unwelcome sexual encounters, she bore two children and, at some point, Newsom provided her with a â€Å"luxurious† cabin adjacent to his home near a â€Å"beat down path.†[4]  As it turns out, Celia fell in love with George, a slave owned by Newsom who was aware of his [Newsom’s] sexual assaults.     George gave Celia an ultimatum demanding that if she did not â€Å"force Newsom to stop having sexual relations with her† their relationship would be over. [5]   Celia confronted Newsom who ignored her warnings.   She even turned to his daughters for help.   It was then that Celia decided she would â€Å"resort to a physical attack to repel his advances.†[6]When Newsom arrived on the night of June 23, 1855 as promised, Celia hit him with a stick.   When he reached for her again, Celia â€Å"raised the club with both hands and once again brought it crashing down on Newsom’s skull.†[7]   Celia disposed of the body by burning it in the fireplace.   On the following morning she asked Newsom’s grandson, Coffee Waynescott, to â€Å"clean out her fireplace† and â€Å"carry the ashes out† in a container and, after which, he â€Å"spilled the remains in the grass.† [8][1] Melton A, McLaurin, Celia, A Slave: A True Story of Violence and Retribution in Antebellum Missouri (Athens: University of Georgia Press), 3; 4-8, (hereinafter cited as Celia, A Slave).[2] Under the terms of the Compromise, Missouri was to be admitted to the Union as a slave state; Ibid, 8.

Pop Art and Mass Media Essay

Alloway views pop art as a form of tool that was used to break the hegemony of elitist aesthetic standards that had been set over the years and that had defined art. In a sense, pop art could be seen as a democratization of art just as in the area of governance the advent of democracy in modern society broke the power of absoluteness wielded by the monarchy and its aristocracy. Alloway is of the opinion that though population explosion and the industrial revolution in Europe during the era of the Enlightenment had a seismic effect in transforming society, this transformation had been lacking in the field of art as traditional ideas still persisted. In effect these traditional ideas became a limitation on the development of art. Consequently, having pastoral and elitist conceptions about art prevents an art critic, for instance, from appreciating art forms emanating from the mass media. The mass media and pop art present an artistic relationship where themes and expressions of pop art are easily discerned as offshoots of the mass media. Andy Warhol’s John Wayne Silkscreen – 1986 (figure 1 beneath) is a typical example of artistic expression based on a popular theme/personality in the mass media. Again Andy Warhol’s Triple Elvis – 1963 (figure 2 beneath) shows the intersection between mass media and pop art. In both the John Wayne Silkscreen and the Triple Elvis, popular personalities in the movies (and in popular music i. e. ith regards to Elvis) patronized by the masses are depicted holding guns in typical Western movie fashion. The persistence of pop art that draws its themes and expressions from the urban instead of the conventional and pastoral, and from the mass media/popular urban culture as against the artistic standards of the minority elite, signifies the demise of elitist definitions and standizations of art. The process of change in the fine arts as compared to the mass arts is however mitigated due to the fact that the fine arts have traditionally been invested with the ‘duty’ of being the repositories of cherished societal values. Thus change or acceptance of change in the expression of the fine arts comes with the added hurdle of having to deal with time-bound values. The mass arts on the other hand are easily adaptable and readily responsive to technological changes. Advances in electronics have for instance changed the cinemas, TV and radio in the way they films, serials and programmes are presented to the audience in a way that appeals to them as consumers. These technological advances spur on consumer centric presentations in the mass arts. The advent colour in cinema and TV for can be seen being replicated in mass printed glossy colour magazines. The ability of the mass arts to also depict fantasy in a way that appeals to audiences can be seen being depicted in popular comic art for example. Just like the examples of John Wayne and Elvis given above, the focus on heroes and personalities (some of them sex symbols) are fantasies in the mass media that audiences readily identify with and these consumer centred fantasies depicted in art become a continuum from the mass media.
