Mirror by lucy grealy - Essay Example Society is an organization where people share common ideas as well as economic and social infrastructure. In a society people should support each other and they also have to maintain a good relationship. Usually, there is a social and emotional bond between the people of a society. But due to the harsh experiences in her life, Grealy forms a different concept of society. She accepts society and the nature of truth in her appearance because she accepts the correlation of her face and herself. She forms a repulsive image of the society where people are not cooperative and supportive. She accepts the fact that her face is ugly but she internalizes this fact and continues to live on. She also understands that the image shown in a mirror or the social mirror is not real. She believes that the society lacks values and people do not take notice of any values. Nature did not give Lucy beauty, which was a popular social demand. This was due to the fact that she had to undergo chemotherapy fro m a very young age. The society in which Grealy existed, failed to show empathy towards her. They were not able to accept Grealy as she was. They never bothered to help her.

Bill Clinton and Globalization Research Paper Example | Topics and Well Written Essays - 2500 words

Bill Clinton and Globalization - Research Paper Example Clinton’s main focus was on handling the instability across the world through globalization. The other factors among the list of priorities were innovation and technology, decision making and finance. Integration of the world economy has been one of the prime concerns of Clinton. But the concept of transformation of the globalization into a unified and homogenous structure driven by free trade and capitalism was confronted with serious opposition also. It was said that the entire world has not been able to benefit from globalization and bringing the civil society in the scene was the only way of dealing with the problems. The project tries to bring forth the steps taken by Clinton in initiating outsourcing as a major step towards globalization (Weier-a, 2008). Bill Clinton chaired the â€Å"Global Fairness Initiative (GFI)† (Global Fairness Initiative, 2003, p.1) which was an organization created to introduce and enhance free trade which would simultaneously preserve th e labor, environmental and human rights standards in the world. The promise made by Clinton was to implement responsible investment and trade which would create economic opportunities and jobs across the world and would lead to the improvement of millions of lives while protecting the human rights, environmental and labor standards (Global Fairness Initiative, 2003, p.1). The promotion of outsourcing was one of the major steps towards globalization by Clinton. Outsourcing was considered to be inherent to free trade. Outsourcing was considered to be a new variant and a budget balancing tool which required farming out whenever possible. Clinton recognized that outsourcing would allow firms to provide service at a low cost at a higher quality that which the Government would produce. In the recent years outsourcing has evolved as a positive business evolution which moved towards flexibility and nimbleness Bill Clinton and Globalization It was Bill Clinton’s assumption that global ization was something inevitable. He encouraged the concept of free trade which was a major step towards globalization. He believed that low process would lead to low prices, increased exports and this would eventually build a stronger economy. â€Å"The economic benefits of the tariff reductions we negotiated during the Clinton administration represent the largest tax cut in the history of the world† (Klein, 2003). In 1998, the economic transition which he had predicted long back was actually taking place. The economy was appearing and functioning in such a way that seemed to be beyond imagination few years back. Unemployment rates were falling significantly and the inflation rates seemed to remain at historically low rates. Prosperity was appearing and increasing at all levels of income. The average household income increased by an amount of 35% during the span of eight years that Clinton has remained in office. Technology had changed the conventional notions of time, space and borders. Globalization was able to change the traditional and regular routines of the middle class family. This was a significant transformation according to Clinton (Klein, 2003). He said the globalization would yield a global economy which would have profound effects on workers, their works and their wages. It would

Red Spot Markets Company Essay Example | Topics and Well Written Essays - 1500 words

Red Spot Markets Company - Essay Example Possibly, a third and more strategic issue is the decision to close down the Providence center and shift all operations to Newburgh. First, we try and understand the impact of the first problem. Shrinkage directly impacts retailer margins since it is a loss of inventory. This is of concern to the senior management. At the operational level, this leads to a different kind of conflict. The DC (Distribution Center) loads cartons in which, as per the delivery note or shipment advice, a specified number of bottles or packs of a particular product is packed. However, when the stores receive the goods and they find shortage, then they report it as short receipts and make a note accordingly. Often, the DC employee states that it is not his problem and blames in-transit loss of goods. For the stores, it is a problem since the shelves would not be fully stacked. Repeated complaints from stores would imply the seriousness of the problem. Yet, managers who seek to address such problems need to d iscuss with DC personnel and with the store teams on these issues. Decisions cannot be taken without consulting both sides. The second problem is handling a dominant employee who seems to exert both a positive and negative influence on his team members. The situation would have been positive if, even in Bigelow’s absence, the DC operated smoothly with very minor lapses due to lack of leadership. But we find clear evidence that he has been able to influence his co-workers to sabotage daily operations because of his unjustified suspension. This kind of negative influence is bound to affect the company in the long run. It shifts the focus from an impartial, unbiased dedication to work to dependence on a single person, who can drive day-to-day activities. For an aggressive DC manager, Bigelow is bound to create problems. He is unlikely to take orders from his superior. In fact, Bigelow has been trying to lord over his superiors. A second problem is that such a leadership (Bigelow ’s) would foster a cover-up of real problems. For instance, if two or three poor performers are there in his team, then Bigelow would try to cover their shortcomings. This would impact worker morale and productivity. A similar attitude of covering up of performance metrics (such as shrinkage) would ensue since we have glimpses of such acts towards the end of the case. The third issue, more strategic in nature, calls for a decision to shut down the DC in Providence and shift to Newburgh. This could have a bigger impact on the company. The first is that there must be a thorough assessment of whether the Newburgh facility can handle the volumes which were earlier managed by the Providence DC. It needs proper computation of DC space, forklift movement space and additional personnel needed to man operations. The second point of concern is the distances which need to be served if all logistics were to be managed from the Newburgh center. Response time may increase leading to empty or partially replenished shelves at the retail stores. This would directly hit the store revenues. The third issue would also lead us to the problem of managing retrenchment or re-allocation of personnel from the Providence DC. Employees with strong roots may resist any attempts to re-locate and they may be willing to give up their jobs. Additionally, this could result in legal problems if any of them decide to sue the company. Plus, there could be talented, good performers at the Providence DC, who may not

Family on Film Movie Review Example | Topics and Well Written Essays - 500 words - 1

Family on Film - Movie Review Example This paper makes a reflective analysis of the films Crooklyn and To Kill a Mockingbird in order to establish how they convincingly portray the stress permeating families and how the children in these movies deal with stress within their families. A careful observation of how Spike Lee presents the plot in the film Crooklyn confirms that the filmmaker makes crucial decisions to show how stress permeates a family and how the family deals with various difficulties. In an insightful review of the movie Crooklyn, it becomes lucid that Spike Lee has been highly effective in reflecting the stress within the family of five children and how the young girl Troy Carmichael deals with this stress. In this movie, the main character Troy is presented as facing various types of stress in her family, which consists of the four troublesome brothers and the stressed parents. All through the movie, the careful viewer comes across a brave and maturing young girl who efficiently manages various stressful moments in her daily life. It also comes to the notice of a close observer that the director makes use of arbitrary reflections and storytelling in the movie to suggest how Troy realizes the realities of life around her.

E-government problems Research Paper Example | Topics and Well Written Essays - 5000 words

E-government problems - Research Paper Example Past literature illustrates the application of e-governance within federal offices (Groznik, Kovacic & Trkman, 2008). This includes communication through information systems and the internet among federal offices. Researchers demonstrate that such communication is the prerequisite to the ability of government offices to have effective relations (DG Information Society and Media, 2007). It is in this regard therefore that e-governments have been said to employ technology in ensuring that all of its offices work towards a common goal of providing efficient and effective services to the public (Chee-Wee & Benbasat, 2009). It is however notable through a review of past literature on e-governments, that scholars have not reached specific definitions for all aspects of e-governance. This is demonstrated by the different understandings and descriptions of issues in e-governance such as effectiveness, applicability, user friendliness and the various applications that are used in the implemen tation of e-government across all platforms of government operations (Ong, Katerattanakul & Seok Jeong, 2008). Past research literature agrees that e-government and its design are aimed at benefiting citizens (Sarantis, Smithson, Charalabidis & Askounis, 2010). This includes workers across a nation that implements e-governance, ordinary citizens, practitioners and researchers (Kazemikaitiene & Bileviciene, 2008). The definition of e-government reveals how citizens benefit from its applications. For example most of past literature on the topic reports that e-government is a set of technological tools and applications which are designed with an aim of facilitating communication and interaction between citizens and the government (Teo, Srivastava & Jiang, 2008). More notable is the fact that past literature agrees that the satisfaction of citizens on e-governance is less satisfactory in most states (Svard, 2010). This is attributed to the challenges or problems that are faced by e-gove rnments as described in the following sections of the literature review. Failures in E-Government Leadership The process of acquisition, design, installation and implementation technology within government institutions, agencies and offices requires that proper monitoring and control is guaranteed for success (BBC, 2012). Even though past literature presents the various processes of developing e-governments differently, it is evident that proper leadership is vital for successful development of information systems within all levels of governance (Hakan & Karl, 2009). It is in this regard that researchers have focused at an evaluation of the leadership processes within government agencies that employ technology. Researchers report that several failures characterize the leadership of government agencies and departments in regard to the development of e-government applications (Groznik, Kovacic & Trkman, 2008). Among the most notable failures in leadership include poor control and mana gement of the initiation stage of e-government development and poor control of the implementation

Extremely Disturbing Accident Essay Example for Free

Extremely Disturbing Accident Essay There was an extremely disturbing accident a couple of years ago. I will never be able to forget that scene which made Daniel lost his words and made him stay in the darkness for such a long time. Daniel was a wonderful man who cared about his family more than anything else. He had a lovely wife who was called Mary and between them, he had the most adorable daughter. I have never seen such a caring and loving family who knows to take care about their neighbors as well. They were especially kind to me who was living next door, old and alone. They knew I had no relatives so they often invited me at dinner and on the special occasions such as Christmas and Birthdays. They regarded me as a member of the family. We used to sing every night and, oh, I remember, the family was very fond of reciting poems. Therefore, we had this party in which all had to recite favorite poems very often. Daniel used to write the poems by himself and the poems were always about love in the family and each time, we were touched and impressed by high qualities of them. However, the happiness did not last long. On Daniels 40th Birthday, Mary and her daughter, Kate, and I planed to surprise him by taking a birthday cake and a lot of nice food to share with his friends to where Daniel was working. In spite of the fact that Daniel was very angry when we once visited him long time ago, he said the place is too dangerous, we were taking food to where Daniel was working. Having thought back about what he said, he was right; He did a lot of physical works for building up the structures and the place where he worked was very dangerous indeed. Kate was singing, excited with joys, she couldnt wait to see her dads smile at her little- hand made birthday card. She was running down the hill and at the same time, I just realized that she is not safe any longer at that distance. Mary and I were running after her, shouting to stop, but it was too late. By accident, one of the workers dropped a huge-hard wooden material from high floor of the building, and Mary was hit by it so hard that even before the ambulance came to help her, she was already gone to the other world. Daniel thought her death was his fault and he quit the job. He acted like an insane person and people started to avoid him, even his wife gave up trying to turn him back to normal. At last, they got divorced in few months. I didnt see Daniel for a few months around his house, and then I found him in his garden. I asked him whether he feels better and he always nodded at my questions. I noticed he became the person I used to know, the person before faced his daughters death, but I knew something was wrong. He was quiet, too quiet. His eyes were always full of sorrow and made my heart broke. They reminded me of Mary who was gone long ago. I did my best to make him to speak again, not out of pity, but I felt I am the one relative left to take care of him. He hardly got out from his room; it was so hard to make him to get along with people, to get socialized again. I thought it would be impossible to make him speak again unless Mary comes back to him. One day, I have succeeded to take him to the poetry club where he used to love to go and listen to the poems. I thought this rally was the last chance I have and played to God desperately. That, that was a miracle; he was listening the poems quietly and suddenly, he stood up. After a while he started to mumble something and soon he made a perfect sound. I was frozen, alert. The people around him listened to him. He found the music of speech which was concealed in this heart deeply for a long time. When he is done, before the applause, we observed the flowers silence. A thrush sings and the daffodils are flame

Alison, Bruce: Two Genders with a Common Identity

Alison, Bruce: Two Genders with a Common Identity Ivory Coast is a west African country where homosexuality is not acknowledged. Even though it is practiced by a minority, they have to keep it secret. Fun Home is about identity. In a tragicomic tone, Alison Bechdel transcends two secrets in her autobiography. These secrets are about gender and identity. Fun Home is home to a special family, an old artificer Bruce Bechdel and his family. This family is not ordinary. After Bruces death, which his daughter Alison, considers being a suicide, his homosexuality is discovered. Alison believes her fathers suicide might be due to the declaration of her lesbianism. She has a common past with Bruce; they both have been hiding the truth about their gender preference. Bechdel uses the art of allusion to describe a complex relationship between Bruce and Alison. She says, In our particular reenactment of this mythic relationship, it was not me but my father who was to plummet from the sky. (Bechdel 4). Through this metaphor, Alisons situation is t he contrary to the real story, the daughter should have been the one to plunge. It is an unusual situation describing two characters, where Bruce is a man and he likes men. Alison is a woman but she prefers females. Physically and emotionally, Bruce and Alison experience distance. Yet, being gay they both had much in common. Physically, Alison was distant from Bruce. She starts her autobiography with an image of herself with her father playing the Icarian Games.   With this game, Alison presents one of the few physical contacts with her father. The author alludes to her father as being both Icarus and Daedalus, an ultimate artist who sees his children as working materials. Bechdel says, Daedalus, too, was indifferent to the human cost of his project (Bechdel 11). This aspect of the book shows the lack of affection establishing a gap between father and daughter. It also describes a complicated relationship between these two characters, characterized by an obstinate Bruce forgetting family affection. Not only physical, this detachment was also emotional. Alison early suspects the sexual identity of her father. Seeing her father using a bronzing stick was proof that he belonged to a different moral ethic from the norm. Bruce was gay but to further complicate the situation he preferred teenagers. Bruce had a secret relation with Roy, his yardwork assistant/baby-sister. These two characters were opposite, Alison feeling comfortable with short hairs and male attitudes, sees her father as a feminist. During an interview on the NPR radio, Bechdel says, Its like one of the first things I remember is wanting to wear boys clothes and fighting with my dad about it. (NPR). She was prevented from expressing her masculinity. Bechdel illustrates this aspect in a discussion between Alison and her father when Bruce says, I dont care! Next time I see you without it, Ill wale you. (Bechdel 97). Holding his daughter away from her desires, Bruce creates more distance than there was already. Despite being distant Alison and her father share similarities, they both had a secret. This disparity from Bruce pushes Alison into more understanding of her father. In the quest to reconstruct her fathers history, many common aspects show up. After the brutal death of Bruce, that Alison alludes as a queer in every sense of that multivalent word, she unveiled her fathers secret. Bechdel emphasizes the detection of this secret by a sensual picture of Roy in the book. She says, Its low-contrast and out of focus. But the subject is clearly our yardwork assistant/babysitter, Roy (Bechdel 100). The picture has a double effect in the book. Certainly, it shows the evidence of Bruces sexual identity but it also characterizes the sexual longing of Alison.   Watson in her analysis of fun home says, The drawn photo is surrounded by elongated dialogue tags that chronicle Bechdels conà ¯Ã‚ ¬Ã¢â‚¬Å¡icted responses, acknowledging both her identià ¯Ã‚ ¬Ã‚ cation with her fathers erotic de sire for the aesthetic perfection of the boys body, and her distanced critique as a sleuth of this evidence of his secret life. (Watson 41). Still in the 1970s homosexuality was to be hidden in the society. Bruce was keeping his sexual preference secret. Alison was in the same situation too. In a business trip to Philadelphia, they met a woman dressed like a man who had a short haircut. Alison was amazed, but when her father asked her if she wants to be like this woman, she answered no. But her true answer would have been yes. She kept her sexual identity secret. Furthermore, the secret they each had, was about their identity. Like Bruce, Alison was gay. She developed her masculine traits early in her teenage years. Alison says, Indeed, I had become a connoisseur of masculinity at an early age (Bechdel 95). At a young age, she was a non-practicing lesbian. Yet she shares this same reality with her father. In a New Times article, Gustines says, Shes a lesbian, and sexuality looms large in her memoir. Bechdels father, Bruce, was gay (as she puts it: a manic-depressive, closeted fag), and Fun Home is at its heart a story about a daughter trying to understand her father through the common and unspoken bond of their homosexuality (Gustines). Obviously, Alison and her father had this identity in common, they were both homosexuals. In addition to sharing a similar identity, Alison also had common interests with Bruce. Watson in the description of Bruce Bechdel says, Bechdels story about the meaning of Alisons childhood memories not only links her sense of her own sexuality to her fathers secret gay side, it also produces a recognition about how their lives are linked over generations (Watson 42). From Watsons analysis, there is this aspect of their life that connects them. This connection is emphasized when Alison in Bruces twelfth-grade class. They were so consumed by similar thoughts and readings that the class was mostly animated by only Alison. She says, Sometimes it was as if Dad and I were the only ones in the room. (Bechdel 199). As if to confirm their similar identity, Bruce decided to bring his daughter to the film. During their revelation one to another, Bechdel states, It was more like fatherless Stephen and sonless bloomà ¢Ã¢â€š ¬Ã‚ ¦ (Bechdel 221). This particular moment opens the barrier between these two characters. For the first time, they share unreservedly their sexual orientation. In many places, especially in West Africa, it is almost impossible for homosexuals to express their identity. The subject of homosexuality is still taboo in some parts of these countries. Through her novel, both tragic and comic, Bechdel draws attention about this particular topic. She shares this theme about homosexuality represented through Alison and her father. These characters struggling to make an intense connection. However, they share similarities. Certainly, this family is more complicated relation because father and daughter share an identity not acknowledged. Fun Home comes out of the ordinary because it touches a sensitive subject that concerns the whole society. Work Cited Bechdel, Alison. Fun Home: A Family Tragicomic.

Smooth Muscle Contraction | Experiment Smooth Muscle Contraction | Experiment Background information on smooth muscles   Smooth muscle is one of three muscle fiber types found in animals. Unlike skeletal and cardiac muscle cells, smooth muscle cells are not striated, and have single nuclei. Smooth muscles are typically under control of the autonomic nervous system, and do not contract voluntarily. Smooth muscle contracts slowly, and does not exhibit the characteristic twitch seen in skeletal muscle. In addition, smooth muscle is not prone to muscle fatigue, making it an ideal component of sphincter muscles. Smooth muscle is found in the gastrointestinal tract of many animals, and is responsible for peristaltic movements. Smooth muscle contractions are affected by calcium and potassium ions. Calcium ion influx into the smooth muscle cell initiates a contraction. Potassium ion concentration in the extra cellular medium affects the resting membrane potential of the cell, bringing it closer to or farther away from its threshold voltage. Neurotransmitters affect different types of smooth muscle differently, depending on the association of the smooth muscle with excitable cells. In general, acetylcholine increases the muscle cells permeability to calcium, while epinephrine decreases the cells permeability to calcium. Introduction and aim of the experiment The following report was to test a smooth muscle which was collected from the intestine of a rabbit. The main of this experiment was to see how the surrounding environment of the muscle could affect how muscle contracted. The experiment consisted of different environments and the muscle was monitored and results were recorded of the amplitude and the frequency of the wavelengths. The levels of muscle contractions and relaxations were measured using a transducer, a D.C amplifier, and a laboratory computer. Overview of experiment The smooth muscle was a small part of the intestine which was prepared correctly by trimming off the attached mesentery and fat. This experiment only required one piece of this smooth muscle and this was then placed into a beaker which was aerated and fed Ringer-Locke solution this is an aqueous solution containing the chlorides of sodium and potassium and calcium that is isotonic to animal tissues. The experiment only required one piece of small intestine, which had the length of 2-3 cm long. The intestine was held in place with a tissue holder, and was attached to the transducer via a piece of string. The transducer detected contractions and relaxation of the muscle, and via the D.C amplifier showed on the computer the frequency and strength of the contractions and relaxations. The solution that the muscle was placed in was kept at the temperature of 37 Celsius apart from when the environment condition changed was the temperature. This type of setup is known as in vivo preparation. This preparation of the smooth intestine allows a precise control of the environmental conditions. Brief description of test carried out The test which was carried out had six parts to it. The first part of the experiment was to gain initial control of the muscle this was done by having optimum conditions for the smooth muscle so it could achieve a steady rate of contraction and relaxation. This was achieved by adding Ringer-Locke solution and keeping it aerated. By having this set up it allowed the muscle environment to be very closely met to the ideal body environment where the muscle would have a good contraction and relaxation rate. The muscle was left in this preparation until the readings on the computer were constant (about 4 minutes) the initial control was labelled using the comment bar. The next environment was non-aerated this meant to turn the air supply off which was coming to the bath where the muscle was held. Then the Ringer-Locke solution was removed from the bath and fresh Ringer-Locke solution was then placed into the bath. The reason for removing the old solution was to prevent any inaccurate readings as the solution could still have contained oxygen which would have affected the results. This part of the test was recorded after every 5, 10, 15 minutes and the results where inserted into a table. The main purpose of using this environment was to see what the muscle contractions and relaxations are when there is a lack of oxygen. This part of the experiment was again labelled on the comment bar. The next part of the experiment was to remove the Ringer-Locke solution and replace it with 50ml of glucose free solution and again results were recorded after every 5 ,10, 15 minutes and recorded into a table. The fourth different environment was change in temperature. The Ringer-Locke solution of 37 Celsius was replaced with a Ringer-Locke solution that was cooled to 4 Celsius. The purpose of this environment was to test the muscle activity in a cold environment and to analyse the effects. The fifth environment involved the use of calcium free solution this replaced the Ringer-Locke solution. This was analysed for 5 minutes to see how the muscle activity was affected. The final environment was to do with changes in the pH. The pH was changed from pH7 which is neutral to a different pH. The solution with different pH was prepared before hand and the purpose of this environment was to see what effect a pH change would have on the muscle activity. After each part of the experiment initial control was established before moving on to the next part the reason for this being to keep the muscle running properly before each part of the experiment and to cause less damage to the smooth muscle. Also each part of the experiment was labelled on the comment bar this was done to show each different part clearly so it was not confused. (Clear methods are shown in the printouts) To work out the amplitude of the graph recording two figures were recorded one being the peak of the wave and the other being the lowest part of the wave To work out the frequency for each part of the experiment the amount of waves were recorded in a minute time period. The frequency in this case was how many times the muscles contracted and relaxed in a minutes. The amplitude was the strength of each contraction and relaxing of the muscle. The maximum and minimum amplitudes were collected for each environment and recorded; the amplitude chosen was picked at random as well as the minute where the frequency of waves was calculated.   Discussion of results Firstly a diagram of the intestine is needed to show how it works and what different types of cells it contains. This is needed as it will help to understand why the muscle behaved differently when tested with six different environments. A diagram of the small intestine is shown below; The small intestine contains the 4 basic layers which are serosa, muscularis, submucosa, and mucosa. Small intestine wall is composed of the same four layers that make up most of the gastrointestinal tract: serosa, muscularis, submucosa, and mucosa. The mucosa is composed of a layer of epithelium, lamina propria, and muscularis mucosae. The epithelial layer of the small intestinal musoca consists of simple columnar epithelium that contains many types of cells. Some of these are the following: Enetrocytes these help with the transport of substances from lumen of the intestine to the circulatory system, synthesis of the glycoprotein enzymes needed for terminal digestion and absorption. Goblet cells these are unicellular mucin also known as secreting glands. Paneth cells these are located at the bottom of the intestinal glands. Their main function is their secretion of granules which contain lysozyme this enzyme helps breakdown bacteria also known as phagocytosis. Paneth cells may have a role in regulating the microbial population in the small intestine. Enteroendocrine cells these are mostly found again in the lower parts of the intestinal gland known as the crypt. The main function of these cells is to release several hormones. The main one beings cholecystokinin, secretin and gastric inhibitory peptide these help increase pancreatic and gallbladder activity. Intermediate cells these are young enterocytes and goblet cell which are able to withstand cell division. Apart from the smooth muscle many other cells and vessels make up the intestine. The small intestine also contains submucosal artery and vein, lymphatic vessel, submucosal plexus, circular layer of smooth muscle, and myenteric plexus. All these tissues, cells, and vessel combine to make the small intestine wall. The smooth muscle in the control environment was able to obtain a steady frequency through out its 4 minute period with 15 waves per minute. The waves which were seen were the smooth muscle contracting and relaxing. The amplitude levels of the waves were both quite high showing strong contractions rate the reason for this was that the environment set was to ideal conditions where the muscle could perform its best. It had a max amplitude of 2.10 and min amplitude of 0.78 which shows that having ideal conditions the muscle is able to behave normally without any problems. The effect of oxygen lack of the smooth muscle cause the small intestine to increase the frequency, at 5 minutes no aerated the frequency had first dropped to 13 and after 15 minutes the frequency of contraction and relaxations had increased to 17 the reason or this being without oxygen the smooth muscles started to have spasms as it was unable to contract properly without the oxygen supply needed. Also the amplitude levels decreased quite quickly from 1.94 (max) and 0.47(min) at 5 minutes to 1.58(max) and 0.38 (min) at 15 minutes. The reason for this was that without oxygen the muscle was unable to make the energy needed for strong contractions as the peak is lowered as can be seen on the traces. This was detected by the pull on the string that was attached to the transducer; the pull was not as strong so this was recorded on the traces. So without oxygen the muscle cells are still able to make ATP but a small amount. Only about 2 ATP are produced per molecule of glucose in glycolys is. If there is no oxygen present, the Pyruvate produced in glycolysis undergoes fermentation to regenerate the NAD+ used in glycolysis. This is known as anaerobic respiration, anaerobic respiration generates only two ATPs, and lactic acid is produced. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Some of the lactic acid remains in the muscle fibers, where it contributes to muscle fatigue. Because both the liver and muscle fibers must convert the lactic acid back to pyruvic acid when oxygen becomes available, anaerobic respiration is said to produce oxygen debt The next part of the experiment was to test how the muscle activity differed when placed in glucose free solution. From this part of the test the frequency of muscle activity stayed consistent throughout the 15 minutes. The traces show consistent movement and also the amplitudes levels differed as at 5 minutes (1.34) the maximum amplitude was low then at 10 minutes (1.51) it wet higher and at 15 minutes (1.37) it decreased again to a similar figure which was at 5 minutes. By looking at this result the results are not as accurate as they should have been, meaning they may have been some kind of inaccuracy when following the method as without glucose, ATP can not be made and the amplitude of the waves should have been lower. ATP can be made from glucose which is stored in the carbohydrate glycogen. Through the metabolic process of glycogenolysis, glycogen is broken down to release glucose. ATP is then generated from glucose by cellular respiration. Also ATP can be produced from glucose and fatty acids obtained from the bloodstream. When energy requirements are high, glucose from glycogen stored in the liver and fatty acids from fat stored in adipose cells and the liver are released into the bloodstream. Glucose and fatty acids are then absorbed from the bloodstream by muscle cells. ATP is then generated from these energy-rich molecules by cellular respiration. Without glucose the frequecny should hve increased but the amplitudes levels should have decreased as there was not a sufficient energy source which could supply the muscle so it could contract and relax. The next part of the experiment consisted of placing the smooth muscle into a cooled solution of 4 Celsius from a change of 37 Celsius. There was not much change to the frequency but it did drop a little bit due to the muscle not being used to these environmental conditions. The amplitude differed from the control readings as they had decreased but were still quite high as they had the nutrients in the solutions which helped them to contract. If this experiment was left to carry on then there would be further change as the solution would gradually heat up to room temperature and this would mean that the smooth muscle activity would increase. Calcium plays a big part in all muscle contraction as well as smooth muscle contraction which is different as it does not contain troponin. In smooth muscles calcium ions enter from outside the cell. They then bind to an enzyme complex on myosin; this then breaks up ATP into ADP and then transfers the Pi directly into myosin. By doing this it allows the myosin to activate and from cross ridges with actin. When the calcium is pumped out of the cell, the Pi gets removed from myosin by an enzyme this allows the myosin to become inactive and the smooth muscle is able to relax. This process is also known as myosin regulated contraction. In the experiment where calcium free solution was added it affected the smooth muscle immensely as the frequency of contracting and relaxing dropped to 12. Also the amplitude levels came down as the contractions and relaxations levels were not strong the max being 0.95 and the minimum being 0.47 if this was left for a longer period of time the frequency levels may have dropped more. Without calcium entering the cell the smooth muscle is unable to do the process which is described above. While making the Ringer-Locke solution it is not only the calcium ions which are important to the smooth muscles. Some others are potassium chloride and sodium chloride, the reason these ions are needed because it helps to portray an environment such as the body with ideal conditions. If only distilled water was used it would mean the cells in the muscles would up take the water and blow up. So these ions are used so they are able to keep a concentration gradient and allow everything to work correctly as it would in the smooth muscles natural environment. The final environment was the change in pH levels. The results showed that the muscle had stopped functioning and there was no reading on the traces. This meant that there was no muscle contraction or relaxing. The reason for this was the muscle had broken down the reason for this muscle fatigue was that the low pH had affected the smooth muscle as it was unable to perform in this type of environment. Also as the low pH solution was there for a certain period of time the muscle was unable to remove it and therefore caused the muscle to breakdown. The low pH may have affected the sarcoplasmic reticulum which may lead to the interfere of the intercellular calcium concentrations, this can lead to long term physical muscle damage as muscle fibers are affected. While preparing the isolated smooth muscle many precautions are taken so the muscle can avoid excessive pH changes. One of these precautions which are taken is to make sure that before inserting the small intestine into the bath. The solution will need to be tested with pH indicator test strips which will give a fairly accurate reading of the solution which the smooth muscle will be placed. This is very important as if the pH is incorrect it will mean that the smooth muscle will not perform to its full potential meaning the results achieved will be inaccurate. To gain accurate results all solutions which are used will need to be checked to see if they are the correct pH by using the ph indicating strips. After this test the smooth muscle was unable to reach the control again as the muscle had broken down. If this experiment was done again at room temperature the results would differ as the performance of the muscle would decrease. This is because the optimum temperature inside the body is around 37 Celsius and this temperature allows the muscle to work at an optimum rate. The lower temperature will mean that muscle contraction will be slower as there will be an effect on enzyme reactions as the more heat there is the more kinetic energy there is this will mean that the muscle activity will be good. If acetylcholine was added to the solution bath of the smooth muscle the membrane potential would decrease and the frequency of waves would increase. The muscle will become more active, with an increase in tonic tension and the number of rhythmic contractions. The effect is mediated by enzymes which increases the intracellular Calcium concentration. Another substance which could have been added was adrenaline. Adrenaline allows blood to flow more easily to your muscles. This means that more oxygen is carried to your muscles by the extra blood, which allows your muscles to function at elevated levels. Adrenaline also facilitates the conversion of the bodys fuel source (glycogen) into its fuel (glucose). This carbohydrate gives energy to muscles, and a sudden burst of glucose also allows muscles to strengthen further. Skeletal and smooth muscle muscles differences in structure and function There are many differences between the two types of muscles the differences are stated below: Snmooth muscles Skeletal muscle A smooth muscle fiber has no T tubules, and the sarcoplasmic reticulum forms a loose network throughout the sarcoplasm. Are long cyrindrical cells that contain many nuclei Smooth muscle tissue has no myofibrils or sarcomeres They are striated this shows their precise alignments of their myofilaments. This tissue also has no striations and is called nonstriated muscle. Thick filaments consist of myosin as thin filaments consist mostly of actin. Thick filaments are scattered throughout the sarcoplasm of a smooth muscle cell Each independent cell is stimulated by a motor neurone. Adjacent smooth muscle cells are bound together at dense bodies, transmitting the contractile forces from cell to cell throughout the tissue. Connective endomysium seprates cell Function Differences Smooth muscles cells are an involuntary action and can work slower so they do not have muscle fatigue. Skeletal Muscle contains both Fast Slow Twitch muscle fibers, that allow for a faster reaction where needed, and the opposite is true for the Slow as well Smooth muscle lines your arteries and airways and serves to contract or relax to help control blood pressure. skeletal muscles function almost continuously to maintain your posture making one tiny adjustment after another to keep your body upright They are also present in the iris of the eye to control the size of the pupil in response to light. By the use of the radial and circular muscle. Skeletal muscle is also important for holding your bones in the correct position and prevents your joints from dislocating. Some skeletal muscles in your face are directly attached to your skin They line the GI tract to move food through the intestines. This is done by peristalsis. Skeletal muscle generates heat as a by-product of muscle activity. This heat is vital for maintaining your normal body temperature.
