Effect of Temperature on Enzyme Activity Essay Example

Effect of Temperature on Enzyme Activity Paper The objective of this experiment was to determine the effect of temperature on the rate that enzymes work. The purpose was to determine whether increasing the temp made the enzymes more active, and if so, at what temperature does the activity start to decline. The experiment consisted of thirty test tubes, with 5 test tubes at each temperature. The temperatures used were 10, 20, 30, 40, 50, and 60 degrees Celsius. For each temperature there were four test tubes with a sucrose substrate, a buffer, and an enzyme, and one test tube with just sucrose substrate, a buffer, and distilled water. After the liquids were mixed and left for exactly twenty minutes, DNS was added to each test tube and then each tube was boiled for 10 minutes, and finally the test tubes were removed from any heat and distilled water was added. Finally the blank test was placed in the photo spectrometer, and the results were compared the other four test tubes to determine the absorption rate for each temp. Compared with the best fit line for the given data, the average absorption was plotted and then calculated to determine the micro-moles of sucrose at each temp, and from there the rate of micro-moles of sucrose per minute.

This shows that from 10 to 50 degrees Celsius the enzyme activity increased, however at some point above 50 degrees Celsius the enzyme activity decreased. This implies that enzymes are more active around 40 and 50 degrees Celsius and less active either below or above those temperatures. The data provides grounds for a conclusion that enzymes are more active around 40 and 50 degrees Celsius, and less active on either end, with the activity declining sharply toward either extreme. Introduction The purpose of the experiment was to determine the effect of temperature on enzyme activity, specifically Invertase. Invertase is an enzyme that catalyses the cleavage of Sucrose into Fructose and Glucose. Enzymes are catalytic proteins that are used to speed up reactions. Enzymes speed up reactions by lowering the activation energy needed to complete a reaction in four ways: by bringing the substrates close together, orientating the substrates correctly, promoting acid-base reactions, and excluding water from the reactive environment. In order for a chemical reaction to occur, the necessary components of the reaction must first interact with each other. In most cases, this interaction is orientation specific: one collision between 2 molecules will allow the reaction to proceed while another collision of different molecules will not. The active site of an enzyme not only provides a specific environment for substrates to interact, but correctly orients the substrates involved, allowing the reaction to proceed. Acid-base reactions are a major component of many chemical reactions. Enzymes promote acid-base reactions by bringing proton-accepting and proton-donating R groups of amino acids in close proximity to substrates. Another way enzymes lower the activation energy is by shutting out H20. Enzymes bind substrates so tightly in their active site that some or all of the water molecules in solution are shut out. The absence of water molecules greatly lowers the activation energy for reactions that require a non-polar environment or reactions that occur between hydrophobic substrates. While enzymes do lower the activation energy of reactions, the rate at which they do this depends on many factors. Temperature is one of the factors that determines at what rate enzymes will catalyze reactions. All enzymes have a temperature range at which they catalyze the most reactions. Also at either end of the temperature spectrum, enzymes will cease to work. Enzymes are held together by a combination of Hydrogen Bonds, Hydrophobic interactions, and Vander wall interactions. These weak, non-covalent interactions can only hold enzymes together under very specific environmental conditions (temperature, PH, salt concentration). As any or all of these conditions become too harsh, the non-covalent bonds which hold the enzyme together are no longer able to do so. At the coldest temperatures, enzymes will not work because the particles in a specific solution would not move, and therefore the enzymes will not come in contact with any substrates with which to react. At the hottest temperatures the weak non-covalent bonds are not strong enough to hold the high energy components of the enzyme together. This experiment, while important is in no way groundbreaking. The data collected will not surprise anybody, but it will help to reinforce the conclusion that temperature effects enzyme activity in the way that at extremes of temperature enzymes will not work, and somewhere in between the lack of activity will be the ideal temp for each specific enzyme. Also this experiment will help the class learn firsthand how temperature, and all the other factors that effect enzyme activity, actually do. Each section of the experiment had a specific purpose, to aid in the formulation of a conclusion. The goal was to test the effect of temperature on enzyme activity. To test this, 5 test tubes were heated at temperatures at 10 degree intervals between 10 and 60 degrees Celsius, four with all the solutions present, and one constant with everything except the enzyme. The purpose of the control was to determine the color change (absorption rate) of the sucrose solution compared to a test tube without any enzyme. In case there was a change in color even without the enzyme, the control would determine how much change was due to enzyme activity, and how much was unrelated. After the heating at each specific temp for 20 minutes, DNS was added. The purpose of DNS was to stop the reaction and provide data for how much enzyme activity took place. The DNS reacted with the glucose, and the solution with DNS would change color depending on how much sucrose was separated into glucose and fructose. The more enzyme activity the darker the color, and the darker the color the more light would be absorbed by the test tube while in the spectrophotometer. Without the DNS one would not be able to tell with such accuracy just how active the enzyme Invertase was. The test tubes were placed in boiling water when the DNS was added to speed up the particles and to make sure everything that could react, did. Methods and Materials Initially, fairly large beakers containing tap water were heated to temperatures between 10 and 60 degrees Celsius at 10 degree intervals. When the water in these beakers reached the desired temperature, using whatever method necessary, the water was manipulated to stay at the temperature for as long as necessary, at least 30 minutes. After the desired temp was reached, 5 test tubes for each temperature were prepared, and each test set of test tubes was numbered 1-4, and B. All 5 test tubes were initially filled with .5ML of the sucrose substrate, and .5ML of the buffer. After that four of the test tubes had .5ML Invertase added, while the other had .5ML of distilled water added. Once all the necessary solutions had been added, the set of 5 test tubes, (one control and four with enzyme) for each temperature level were added to the temperature specific bath. The test tubes were placed in the bath in such a way that the test tubes would rest inside the beaker, with the heated or cooled water effecting the temperature inside the beaker. However there would be no contact between the heated water and the solutions inside the test tube. For the next 20 minutes each set of 5 test tubes was kept inside each temperature specific beaker, with the necessary adjustments being made to assure steadiness of temperature. When 20 minutes was up, each set of 5 test tubes was removed, and separated to avoid confusion of data. After the beakers were taken out, 1ML of DNS was added to each test tube in each temperature, then the tubes were covered with aluminum foil, and finally all the test tubes were placed in a beaker with boiling water for 10 minutes. After 10 minutes all the test tubes were removed from the boiling water bath. Next .5ML of distilled water was added to each beaker, then aluminum foil was placed over the top, and finally each test tube was cooled under cold water. After all the test tubes were cooled, each set of 5 was separated and prepared for the spectrophotometer. For each temperature level the following description is the same. The OD was set to 540 nm, and then the temperature blank was used to then set the transmission percentage. Then the four test tubes that contained the enzyme were placed in the Spectrophotometer and their values were compared with the blank test tube. The transmission for each of the four variable tubes was averaged to obtain an average for each temperature value. Finally a graph was made using the given data. The data obtained in the experiment was then compared with the best fit line of the graph of the given data, and the rate of enzyme activity for each temperature was calculated. Using the calculated data, a new graph was made with temperature and rate and the X and Y axis, to show visually the effect of temperature of enzyme activity. Used in this experiment were 6 large beakers, for the heating and cooling of the temperature baths. Also used were a few small beakers to hold the sucrose solution, the buffer, and the Invertase. To hold the 4 variable solutions and the one control for each temp value, 30 regular test tubes were used. To heat the large beakers two electrically powered burners were employed. To write on the test tubes the groups used wax pencils, and finally to accurately measure amounts of each solution syringes were used.

Geography of the Ganges River

Geography of the Ganges River The Ganges River, also called Ganga, is a river located in northern India that flows toward the border with Bangladesh (map). It is the longest river in India and flows for around 1,569 miles (2,525 km) from the Himalayan Mountains to the Bay of Bengal. The river has the second greatest water discharge in the world, and its basin is the most heavily populated in the world with over 400 million people living in the basin. The Ganges River is extremely important to the people of India as most of the people living on its banks use it for daily needs such as bathing and fishing. It is also significant to Hindus as they consider it their most sacred river. The Course of the Ganges River The headwaters of the Ganges River begin high in the Himalayan Mountains where the Bhagirathi River flows out of the Gangotri Glacier in Indias Uttarakhand state. The glacier sits at an elevation of 12,769 feet (3,892 m). The Ganges River proper begins farther downstream where the Bhagirathi and Alaknanda rivers join. As the Ganges flows out of the Himalayas, it creates a narrow, rugged canyon. The Ganges River emerges from the Himalayas at the town of Rishikesh where it begins to flow onto the Indo-Gangetic Plain. This area, also called the North Indian River Plain, is a very large, relatively flat, fertile plain that makes up most of the northern and eastern parts of India as well as parts of Pakistan, Nepal, and Bangladesh. In addition to entering the Indo-Gangetic Plain in this area, part of the Ganges River is also diverted toward the Ganges Canal for irrigation in the Uttar Pradesh state. As the Ganges River then flows farther downstream, it changes its direction several times and is joined by many other tributary rivers such as the Ramganga, Tamsa, and Gandaki rivers to name a few. There are also several cities and towns that the Ganges River passes through on its way downstream. Some of these include Chunar, Kolkata, Mirzapur, and Varanasi. Many Hindus visit the Ganges River in Varanasi as that city is considered the holiest of cities. As such, the citys culture is also closely tied into the river as it is the most sacred river in Hinduism. Once the Ganges River flows out of India and into Bangladesh, its main branch is known as the Padma River. The Padma River is joined downstream by large rivers like the Jamuna and Meghna rivers. After joining the Meghna, it takes on that name before flowing into the Bay of Bengal. Before entering the Bay of Bengal however, the river creates the worlds largest delta, Ganges Delta. This region is a highly fertile sediment-laden area that covers 23,000 square miles (59,000 sq km). It should be noted that the course of the Ganges River described in the above paragraphs is a general description of the rivers route from its source where the Bhagirathi and Alaknanda rivers join to its outlet at the Bay of Bengal. The Ganges has very complicated hydrology, and there are several different descriptions of its overall length and the size of its drainage basin based on what tributary rivers are included. The most widely accepted length of the Ganges River is 1,569 miles (2,525 km), and its drainage basin is estimated to be about 416,990 square miles (1,080,000 sq km). The Population of the Ganges River The Ganges River basin has been inhabited by humans since ancient times. The first people in the region were of the Harappan civilization. They moved into the Ganges River basin from the Indus River basin around the 2nd millennium B.C.E. Later the Gangetic Plain became the center of the Maurya Empire and then the Mughal Empire. The first European to discuss the Ganges River was Megasthenes in his work Indica. In modern times the Ganges River has become a source of life for the nearly 400 million people living in its basin. They rely on the river for their daily needs such as drinking water supplies and food and for irrigation and manufacturing. Today the Ganges River basin is the most populated river basin in the world. It has a population density of about 1,000 people per square mile (390 per sq km). The Significance of the Ganges River Aside from providing drinking water and irrigating fields, the Ganges River is extremely important to Indias Hindu population for religious reasons as well. The Ganges River is considered their most sacred river, and it is worshiped as the goddess Ganga Ma or Mother Ganges.   According to the Myth of the Ganges, the goddess Ganga descended from heaven to dwell in the waters of the Ganges River to protect, purify and bring to heaven those who touch it. Devout Hindus visit the river daily to offer flowers and food to Ganga. They also drink the water and bathe in the river to cleanse and purify their sins. Also, Hindus believe that upon death the waters of the Ganges River are needed to reach the World of the Ancestors, Pitriloka. As a result, Hindus bring their dead to the river for cremation along its banks and afterward their ashes are spread in the river. In some cases, corpses are also thrown into the river. The city of Varanasi is the holiest of cities along the Ganges River and many Hindus travel there place ashes of their dead in the river. Along with daily baths in the Ganges River and offerings to the goddess Ganga there are large religious festivals that occur in the river throughout the year where millions of people travel to the river to bathe so that they can be purified of their sins. Pollution of the Ganges River Despite the religious significance and daily importance of the Ganges River for the people of India, it is one of the most polluted rivers in the world. Pollution of the Ganges is caused by both human and industrial waste due to Indias rapid growth as well as religious events. India currently has a population of over one billion people, and 400 million of them live in the Ganges River basin. As a result, much of their waste, including raw sewage is dumped into the river. Also, many people bathe and use the river to clean their laundry. Fecal coliform bacteria levels near Varanasi are at least 3,000 times higher than the what is established by the World Health Organization as safe (Hammer, 2007). Industrial practices in India also have little regulation and as the population grows these industries do as well. There are many tanneries, chemical plants, textile mills, distilleries and slaughterhouses along the river and many of them dump their untreated and often toxic waste into the river. The water of the Ganges has been tested to contain high levels of things like chromium sulfate, arsenic, cadmium, mercury and sulfuric acid (Hammer, 2007). In addition to human and industrial waste, some religious activities also increase the pollution of the Ganges. For example, Hindus believe that they must take offerings of food and other items to Ganga and as a result, these items are thrown into the river on a regular basis and more so during religious events. Human remains are also often placed into the river. In the late 1980s Indias prime minister, Rajiv Gandhi began the Ganga Action Plan (GAP) to clean up the Ganges River. The plan shut down many highly polluting industrial plants along the river, and allotted funding for the construction of wastewater treatment facilities but its efforts have fallen short as the plants are not large enough to handle the waste coming from such a large population (Hammer, 2007). Many of the polluting industrial plants are also continuing to dump their hazardous waste into the river. Despite this pollution, however, the Ganges River remains important to the Indian people as well as different species of plants and animals such as the Ganges River dolphin, a very rare species of freshwater dolphin that is native only to that area.

Review 5_2 - Essay Example Semi-automated handling systems involves the utilization of typical equipment such as automated guided vehicles, computerizes sortation, robotics, and live tracks. Semi-automated systems are often used to supplement the mechanized handling systems. The general working principle of the system is that it contains a mechanical system, whose operations are automated by either programming or applying other formats (Codourey, Zesch, Buchi & Siegwart, 1995). Automated handling systems are integrated system involving such activities as handling, and controlling of materials by use of fully computerized equipment, in which, their entire operation is fully dependent on the computer instructions directed to them. The system includes digital conveyors; Automated guided vehicle and automated storage and retrieval systems. In these systems, computers direct automatic loaders to pick and place items where they are required. Automatic guided vehicles are driverless vehicles, in which their control unit is connected to a computer interface to manage their function. Automated material handling systems improve efficiency of transportation, storage and retrieval of materials (Viswanadham & Narahari, 1992). Information directed systems combines the control typical of automated handling with the flexibility of mechanized systems. Informational directed systems use mechanized processing controlled by information technology. The most common examples of information directed systems are the RF controlled equipment and the light detected operations. Consumer packaging is a package that is customarily produced or distributed for sale through retail sales agencies for consumption or use by individuals for the purposes of personal care. Industrial packaging is particularly a package intended solely for industrial or institutional use or wholesale distribution (Chandra & Kamrani, 2003). Consumer packaging is an essential in the contemporary society.

Nursing contribution to patients recovery after anesthesia Essay

Nursing contribution to patients recovery after anesthesia - Essay Example My reflection will be done mainly by applying specialist knowledge in the assessment, planning, implementation and evaluation in the caring for the perioperative patient in recovery. In light of this, it is intended that at the end of this essay I will have developed an explicit understanding of psychological, social and cultural influences affiliated with patient care in PACU and how to manage them and their various outcomes. My role as a recovery room nurse was to monitor and treat the post-anesthesia effects of a patient in a Post-anesthesia care unit (PACU). Immediately after the surgery, I ensured that I provided constant care to the patient by following a certain time frame. I constantly checked and treated the patient after every few minutes, until the patient regained stability and was ready for transportation to a hospital room. Hatfield & Tronsons’ (2008) suggests that recovery nurses should ‘’treat the patient not to monitor’’ even to the point of discharge especially bearing in mind the type of anaesthesia the patient may have had, and keeping up to date with evidence based practice and changes that occur in practice in relation to how to manage these patients. Recovery room nurses should ensure that they learn during this period. The Post-anesthesia care unit (PACU) This is the recovery room where post-aesthesia management took place. The other names of this room are the post-anesthetic room (PR) or anesthetic room (AR). I used the room to perform several functions such as close observation of the patient’s vital signs in a more specialized way than in a normal hospital ward. I also provided treatment of post-operative illnesses such as post-operative nausea and vomiting and quick detection and response to any complications. The recovery area usually requires specialized conditions such as an emergency call system for the anesthetists and the nurse, temperature monitor devices and various equipments and drugs. The Royal College of Nursing (2005) suggests that nurses should make additional observations indicated by patient’s condition and according to your local hospital policy as this can improve practice and avoid adverse incidence occurring this promoting patient safety. The NMC code of conduct suggest that health care profession als must maintain a Continuous Professional Development Portfolio hence keeping their practice up to date throughout their working like NMC (2008). NICE Guidelines (2007) guidelines on how to change practice also stipulates that health care professionals can overcome barriers in practice by keeping their knowledge and skills update which is return ensures safer practice in patient care. The hospital staffs I worked with were highly skilled and trained in handling patients with post-anesthesia effects. The room was strategically located near the operating room to allow quick transportation after the surgery. Once patients recovered, I transported them to the main ward where they waited for orders for discharge or given further minor attention. Discharge of the patient from the hospital only takes place, if they regain complete recovery and stability (Royal College of Nursing, 2011). In the recovery room, I learnt that cooperation was necessary to ensure that the patients obtained max imum care. I ensured that I prepared adequately and worked with unity with other personnel to enable quick recovery of

The role of Women in the Middle East

The role of Women in the Middle East There are over half a billion women in the Muslim World in Middle East. They are in Much of the world lack support of the fundamental functions of a human life. Their social Status is low and they receive lack respect by the men. Women in the Middle East also are less nourished than men, less healthy, less opportunity but more vulnerable to physical violence and sexual abuse. Women in Middle East are discriminated by men, religion or even law. They are much less likely than men to be literate or to have a professional or technical education. The only function of women in Middle East is producing children. But the situation has some improvement in nowadays. Some of the women in the Middle- East are standing up and try to fright for their rights. But actually, most of the women in the Middle-East, especially those who live in conservative countries, are still accept their status and the role that they play in the society. (Mahnaz Afkhami, 1996) Women need to play a proper role in the s ociety especially in the conservative society or countries. For example like in Saudi Arabia. The proper role means to be a good children, good wife and good women. In the Middle East societies, most of the people are welcome to have a boy rather than girl. There are several reasons make people prefer to have a boy. First of all, most of the middle-East countries still are the agriculture base community. Therefore, have a boy is more prefer than have a girl. It is because sons are valued for the muscle power they can provide in the fields. Also, in Middle- east there is absence of the adequate social security system. (Ramsay.m.Darik Elsa Marston, 1996) So that sons are supposed to take care their aging parents. But girls on the other hand Often seen as an expense that will not bring family benefits, but only will work for their Husbands family. (Ramsay.m.Darik Elsa Marston, 1996) Furthermore, sons can carry On family name and honor but girls cannot. Therefore, in the eyes of middle- east people Boys are more valuable than girls. This makes the status of girls is lower than boy. Due to the above reasons, the status of girl in Middle East is lower than boy. For example, Most of the name in Middle East always has positive meaning. But some of the girls Names have negative meaning, like Dalenda which means destroy. From this example, We can easy discover that the status of women in Middle East is low. (Ramsay.m.Darik Elsa Marston, 1996). Furthermore, in Middle East most of the girls expect to do more works at home than boys. They need to wash the dishes, preparing food and taking charge of younger children. It is very common to see a child to take care a baby. Girls when they are reaching 11 years old. Then she will be require to be a prefect Islam woman. She will teach by her mother to be a shy and quiet girl. To learn the traditional behavior and skills of Islam. They need to dress more conservative and need to obey their father, brother pr even male relatives or der and advice. They are required to be a prefect girl. Base on the Koran says the seeking of knowledge is a duty of every men and every women. Therefore, even is a girl also will have an opportunity to be educated. However, most of the conservative family in Middle East only willing to sent their girls to the Traditional school. To learn the traditional behavior and norms. The conservative families mainly oppose to sent their girls to the modern school because they believe if a girl learns about something besides the Korans then they might try to communicate secretly with someone outsides her house. Also, the modern education is expensive. The money put on a girl would be waste when she went to live with her husbands family. Therefore, only 38 to 44% of girls in Middle East countries would get a chance to study. (Mahnaz Afkhami, 1996) Although, the girls also can have an opportunity to be educated, but there is a two society in middle- east. For example in Saudi- Arabia require sep arate schools for boys and girls. (Mahnaz Afkhami, 1996) The girl in Saudi Arabia needs work harder at school but they would not have a summer vacations or there are less recreational activities for girls. Furthermore, Saudi Arabia girls need to wear uniform, which is long- sleeved blouse, ankle length skirts or even she needs to wear abba ( Full length black cloak) to school. Moreover, the teaching sllysmulls in Saudi also is quite conservative and old- Fashioned. The schools are teaching the girls how to be a good mother. Also only encourage they be a nurse or a teacher in future but no more. Isam is the majority religion in middle- east, according to the Mohammed speaking, Men have a status above women. And men have authority over women because God has made one superior to the other. Due to this tradition religion, therefore, the women status in the Middle East is low. In some extreme traditional Islamic lands such as Saudi Arabia women are expected to remain strictly obedient to men, womens behavior is not Only the key to her family honor, but also is a key to remain the mortality in the middle East society. Therefore, the western thinking is a kind of dangerous to the traditional society. As this may lets a girl to against her family or fathers order. Moreover, the image of women in right behavior is a necessary safeguard to the culture preservation. Therefore, in many Middle East countries, like Saudi Arabia has a special enforcement Unit knows as religious police. These men aggressively watch the public for such Offenses as women driving and unmarried couples appearing together in public. Also in Saudi Abria women are not allowed to works, study or dress as she pleased. Furthermore, she cannot drive or go out alone. Or even women have no freedom to go to other Countries alone. Womens rights are strictly restricted. ( Martha C. Nussbaum, 2000) Protect the girls honor is the great and important responsibility of the father in middle East. This led out two conservative tradition customs in the middle- east world: Female Circumcision and Honor killing. Women and girls in middle- east countries are affected no matter in urban or rural, educated or non- educated. When a girl is about 5-6 years old then she needs to be circumcised. ( Waris Divie Cathleen Miller, 1999) It is because in the mind of people in middle- east it can prevent a girl from becoming wild and can ensure she will remain virgin until marriage and will then remain faithful to her husband. Or even it can make a girl a woman, purifies, more beautiful. The girls in middle East believes it is another tool for the men to control the women in middle-east. However, the circumcision is quite dangerous to the women. It can result in permanent physical and emotional damage also can cause infections or fatal. (Ramsay.m.Darik Elsa Marston, 1996) so it really is a horrible tradition in the Middle East world. Moreover, if a girl has a Misbehavior then her father or brother will have a right to kill her without serious Punishment. It is because they need to protect the name and honor of their family. Traditionally, the honor of the family depends on the behavior of its female members. So that it is very important for the family to protect female sexual purity. Need to protect the women from sexual misbehavior. Base on the Koran God created sexual desire in 10 parts. Then he gave 9 parts to women and 1 part to men. So women must be closely watched. Therefore, in her familys eyes the longer a daughter waits before marrying, the greater chance that she will disgrace herself with some men. So that most of the girls in Middle East is early married. But the traditional marriage watch in Middle East is lack of Romanic moves but just like a Kind of business. The parents choose the husband for their girl only base on one reason Is this marriage is a right match? The marriage usually is like a kind of alliance Between two families. Furthermore, the marriage will bring th e economic and social Advantages to both families. The girl in Middle East usually has to marry a man she has never met. Or even parents suppose their daughter to marry with an older man. Girls act Like an asset of the family. So the family would like to sell their girls at the highest price. So a girl may be expected to marry a man who can bring the economic benefit to her Family. If the girl wants to disobey her fathers choice then the only way for her can do is run away or attempt suicide. This really is a tragedy in the Middle East world. Wife must need to obey her husband as the male has a dominance status in the middle- East world. According to the Koran says If a wife is rebellious, then her husband should Admonish her, punish her to her couch and strike her. Therefore, the religious gives the Men a right to hit their wife. So the domestic violence is quite common in the Middle East. Also, in the Middle East world polygamy is allowed. That mean man can have more than One wife . Islam allows a man to have up to 4 wives. This is very common in some Conservative countries like in Saudi Arabia. But in fact, women can gain more power When they become older. They will handle the right of household finances, discipline children and not hesitate to speak her mind. In Middle East, it is quite easy for a man to divorce his wife anytime. But if divorce the men need to pay all married cash to his wifes family and the women can keep the gold, jewelly, clothing and need to move back into her fathers or brothers household, under the eye of her male relative. In the tradition view, a wifes primary job is to bear and raise children- especially boys. They are not encouraged to go out for working. It is because working and earning living is the mans responsibility. In fact, if a woman need to go out for working. Then it is a sign to show that her husband cannot support her living. This really is a shameful to the male. But even, the woman can go out for working. However, t here is still sex segregation in some countries. In Saudi Arabia, women can only be a teacher, nurse and mother. The government is restricting the woman to manage business, travel aboard to study, eat in restaurant. Also, women only can work in the restaurant, hospital, newspaper and magazine which for women only. Both in the west and middle east societies, veiling is the popular word for the practice by which a woman conceals her hair and body and sometimes her face. A more accurate term is bijah. The reason for the women to wear the bijah is to hide the sight of womans beauty. Furthermore, it turns their thoughts away from pious, proper behavior: an adolescent youth suffers from frustrated sexual desire and a middle aged man thinks of discarding his wife and finding a much younger and beautiful woman. All of these would led the society become instability. So it is a responsibility for women to prevent these things happen. So they need to put on the veil. Moreover, some of the wome n to go out to the society and can move more freely and not bothered by men. Otherwise, an unveiled woman would likely receive cold stares and insults. Therefore, a woman veiled may say that she feels greater freedom and more safety than she did before adopting the bijah. Furthermore, a veiled woman can prove that she is a good Islam woman and other people will respect her and regard her only as a coworker, fellow students and not as a sex object. Another advantage of the veil is allowed woman stop thinking about her looks and to move concentrate on the important things, such as her job, study and family. Lastly, a girl who covers her face can make her parent to believe her she will behave properly and not attract improper attention. This makes it easier for a girl to go out and spend times with her friends without bother. To conclude, in fact in some Middle East countries the women status has some Remarkable improvement. They can be more independence. There is increasing numbers of women have no men to support them. They can go out for working like in Libya woman even can be a soldier. More and more women love working and see their works as an expression of individual ability, self esteem and growth. Also, more women are choosing to remain independent, postponing or refusing marriage. They even want to work after marriage. Some of them even said they would not marry with a man who wanted them to give up their career. This is really is a sign of improvement in Middle East world. But there is still a long struggle for the women in Middle East to fight for their better life and rights.

Guardian :: essays papers

Guardian He stood at a crossroads. He turned in one direction, and found his small battalion fleeing from the spot, leaving him to the coming evil. Turning the other way he found a dark horizon, and knew that shortly beyond it lay a myriad amount of soldiers, each one branded with the stink of malice. And he lay at the crossroads. The full moon's glow appeared out of the murk of clouds above, as if to warn of coming danger. The lone warrior trembled in the frosty winter air, and let out a deep breath, then watching the mist disintegrate into the air. Sounds were beginning to flow up from beyond that dark horizon. The evil one and his war force were coming. He turned slowly and mounted his mighty black stallion, still trembling with fear and cold. He reluctantly started it at a slow pace toward the edge of the cliff that marked the path of flight. He stared down at the thing that lay at the bottom of that cliff, marveling in its wonder. A small town lay there. It was a simple town, much like any other, but he was suddenly moved by it. It lay at the bottom of the valley, made up of a few buildings and a few families. The people of the town went about their business each day, most likely in the same manner every time. Each person probably knew every other person, and everyone was everyone's neighbor. They never hurt anything, and they probably never would. And now the evil one lay only a few paces away and the poor, ignorant villagers had no idea. No, they only knew their farms and the growing seasons, and each other. And they hadn't done a thing. No, they were innocents in long a bloody war, and they did not deserve their inevitable fate. The man considered this, and was surprised to find a tear in his eye. He squinted and looked down at the town once more, finding it a work of art. The stars above appeared bright orbs of light, protecting the tiny town of innocents below. The heavens above strived to reach down to that place, to save it from the evil of the earth, to protect the innocent. The orbs reached out to the village, acting as great guardians of the pure.

A Cultural History of the Zoot Suit

A Cultural History of the Zoot Suit In the 1944 Tom and Jerry short The Zoot Cat- only the thirteenth cartoon ever made starring that famous duo- Toms would-be girlfriend lays it on him straight:  Boy, are you corny!  You act like a square at the fair, a goon from  Saskatoon.  You come on like a broken arm.  Youre a sad apple, a long hair, a cornhusker.  In other words, you dont send me! The sad cat goes out and buys himself some new duds from Smiling Sam, the Zoot Suit Man, prompting his wide-eyed gal pal to do a one-eighty.  Youre really a sharp character! A mellow little fellow. Now you collar my jive! Around the same time on the American scene- but, culturally speaking, light-years away- a young Malcom X, then known as Detroit Red, also sang the praises of the Zoot Suit, a killer-diller coat with a drape shape, reet-pleats, and shoulders padded like a lunatics cell. (Apparently, people in the 1940s liked to rhyme more than they do today.) In his widely read autobiography, Malcolm X describes his first Zoot Suit almost in religious terms: Sky-blue pants thirty inches in the knee and angle narrowed down to twelve inches at the bottom, and a long coat that pinched my waist and flared out below my knees... hat angled, knees drawn close together, feet wide apart, both index fingers jabbed toward the floor. (We wont even mention Cesar Chavez, the famous Mexican-American labor activist who wore Zoot Suits as a teen.) What was it about Zoot Suits that united such disparate cultural icons as Malcom X, Cesar Chavez, and  Tom and Jerry? The origins of the Zoot Suit, characterized by its wide lapels, padded shoulders, and baggy pants tapering down to narrow cuffs- and usually accessorized with a feathered hat and a dangling pocket watch- are shrouded in mystery, but the style seems to have coalesced in Harlem nightclubs in the mid-1930s and then worked its way out into the wider urban culture. Essentially, Zoot Suits were the pre-war equivalent of the sagging, low-hipped pants sported by some African-American youths in the 1990s or the huge Afro hairstyles popular in the 1970s. Fashion choices can be a powerful statement, especially if youre denied more mainstream modes of expression because of your race or economic status. Zoot Suits Move Into the Mainstream By the time they  were referenced by Tom and Jerry, Zoot Suits were well-ensconced in mainstream culture; you can bet that the studio execs at MGM would never have green-lighted  this cartoon if the style were still restricted to Harlem nightclubs. The apostles of Zoot, you might say, were early 1940s jazz musicians like Cab Calloway who played in front of white and black audiences and were emulated in their dress by youths of all races, though not necessarily their elders. (Before and during World War II, jazz was the dominant cultural musical idiom in the U.S., much like hip-hop still is today, albeit in vastly mutated form.) At this point, you may be wondering from whence the zoot in Zoot Suit derives. Most likely, it was yet another token of the vogue for rhyming in wartime America; zoot simply seems to have been  a jazzy repetition of suit. The young people who donned Zoot Suits as a mild form of rebellion surely enjoyed mystifying their parents with their snappy language and the strange names they assigned to household objects, the same way kids who spend all day texting like to throw out random, impenetrable acronyms. Zoot Suits Get Political: The Zoot Suit Riots In late 1930s Los Angeles, no ethnic group adopted Zoot Suits with more enthusiasm than Mexican-American teenagers, some of them low-level gang members known as pachucos. Shortly after the Japanese attack on Pearl Harbor, however, the U.S. government instituted strict wartime rationing of wool and other textiles meaning Zoot Suits, with their wide lapels and copious folds, were technically off-limits. Even still, many Angelenos- not only Mexican-Americans- continued to wear their old Zoot Suits, and obtained new ones from the black market. Around the same time, L.A. was convulsed by the Sleepy Lagoon trial, in which nine Mexican-American pachucos were accused of murdering an innocent civilian (also Mexican). In the summer of 1943, these explosive circumstances detonated when a group of white servicemen stationed in Los Angeles viciously attacked random pachucos (and other ethnic minorities) wearing Zoot Suits in the so-called Zoot Suit Riots. Ostensibly, the aggressors were incensed by the waste of fabric entailed by Zoot Suits, as well as the flaunting of rationing laws by the youths wearing them. The anti-Mexican feeling stirred up by the Sleepy Lagoon trial, combined with the unabashed racism of small-town soldiers stationed in a big city, were more likely explanations. Amusingly, after the smoke had cleared, a California state senator alleged that the riots had been instigated by Nazi spies trying to estrange the U.S. from its Latin American allies! The Afterlife of the Zoot Suit In the U.S., no fashion trend ever goes truly extinct- even if there are no more 1920s flappers sporting bangs and curls or pachucos dressed in Zoot Suits, these fads have been preserved in novels, newsreels, magazines, and are occasionally resurrected as fashion statements (either seriously or ironically). The Cherry Poppin Daddies landed their only Billboard hit in 1997 with the song Zoot Suit Riot, and in 1975, Zoot Suit was a cut from The Whos ambitious rock opera Quadrophenia. In 1979, a play called Zoot Suit- based on the Sleepy Lagoon murder case and the Zoot Suit Riots- lasted for 41 performances on Broadway. Whats more, the outlandish garb sported by inner-city pimps in countless exploitation movies is based on the Zoot Suit. And, of course, you can always watch The Zoot Cat on YouTube, not to mention various electrifying performances by Cab Calloway in full Zoot Suit regalia.

Lack of Health Care for the Working Class Research Paper

Lack of Health Care for the Working Class - Research Paper Example However, despite dramatic increases in expenditures, inequities exist within the Medicaid system that limit distribution of health care resources and affect health outcomes. Employer-sponsored, private health insurance coverage has declined gradually since the late 1970s (Jacobson and Buchmueller, 2007). In 2010, the number of uninsured Americans approached 49.9 million (U.S. Census Bureau, 2010a). Two major trends are driving the decline: First, changes in the labor market, including the decline in manufacturing jobs, the increase in service-jobs, and the growth in temporary and part-time employment have produced more "benefit-poor" occupations. Second, declining real wages, combined with employer moves to shift rising health care costs onto employees via increased premiums, deductibles and copayments, has reduced the numbers of employees who can afford health care coverage and the extent of that coverage (Swartz, 2009). Working class and women are especially vulnerable to lack of access to employer-sponsored coverage, given the structure of private health care insurance. In the United States, individuals generally qualify for employer-sponsored health insurance plans in one of two ways; as workers in occupations where health insurance benefits are offered to employees, or as dependents or spouses of covered workers (Kim & Muntaner, 2011; Buchmeuller and Valletta 1999). Direct coverage, as workers, is now and has been limited for working class and women due to their historic and continuing concentration in the secondary sector of the labor market. That is, lower working class and women are more likely than others to be employed in the kinds of occupations that are becoming more prevalent and that are less likely to offer coverage; i.e. service jobs, non-unionized jobs, and part-time and temporary work. Indirect, or spousal coverage, though limited to women legally wed to men whose employers offer th e benefit, provides

See attachment - Essay Example According to an online publication, the public sector has been a leader in asset management practices for a long period. The private sector has been lagging behind with players having little interest in the theory. Consequently, there was a lot of mismanagement of resources in the private sector in comparison with the public sector that was achieving sanity at the time. Government agencies had been empowered to investigate public corporations that were mismanaging funds. The agencies were mandated to carry out an audit of the resources that had been allocated to public companies to detect discrepancies that were costly. They made an inspection of government institutions such as the police department, public hospitals, and local authorities among other areas that the government played an imperative role. A task body was formed in the United Kingdom to try and establish the importance of asset management to the strategic plans of an organization and its contribution to profits. The fin ding of the report indicated that although technical skills contributed significantly to the performance of an organization, the role of asset management towards the success of an organization could not be ignored. Consequently, the importance of asset management is one of the factors that stirred the University that investigated correlation Between asset management and the performance of an organization. The study unearthed shocking findings of the notion of asset management. It was created that a majority of people were unaware of the roles asset management played to the success of a business entity2. Despite the fact that the research came up with incomplete evidence, similar studies were carried out in the 1990s.Meaningful recommendations were arrived at that saw companies adopt cost cutting measures in production processes. In addition, new methods of managing physical assets were
