Sterile Service Department Essay Example | Topics and Well Written Essays - 500 words

Sterile Service Department - Essay Example The essay "Sterile Service Department" talks about the hospital sterile services department which is operated by a specialised group of staff who provide an essential service by supplying the operation theatres with sterile instruments and departments with specific items required for patient care.After each use, the medical devices undergo various decontamination processes to render them safe and for reuse on patients and for staff handling. Prior to beginning the decontamination, the used medical device is first received by the sterile services department in a collection container specifically meant for this purpose and is subjected to reprocessing. It is essential that the SSD staff need to check the device and to notify the user if any part of the equipment is damaged or missing on receipt. This is followed by a series of interdependent decontamination procedures like cleaning, disinfection and sterilisation to ensure complete elimination of microbes and other contaminants from th e reusable medical device. Cleaning is the first step in decontamination and is an essential prerequisite for the next stage namely disinfection. Cleaning is done either by mechanical means using an automated washer disinfector or an ultrasonic bath comprising warm water rinse, power wash, disinfection using a detergent and a drying phase. The choice of detergent depends on the nature of the equipment and the user follows the instructions of the manufacturer. For delicate or complex medical devices, manual cleaning is normally preferred.

Effect of Using Facebook as a Teaching Tool on 7th Grade ESL Students Essay

Effect of Using Facebook as a Teaching Tool on 7th Grade ESL Students Motivation - Essay Example One of the main ideas for student motivation and involvement is the use of interactive technology. Smith (1997) has established that use of technology has positive effects on reading and writing . Further, Mayher (1990) and Littlewood (2001) has also expressed that students must be provided a sense of purpose and a sense of participation in learning. On the other hand, Childs (2009) has discussed the benefits that Facebook can yields in language learning owing to its ease and interactive features. Thus, I plan to use Facebook as a teaching tool to increase motivation and participation of my 7th grade students. The purpose of this Action Research study is to examine the effects of using Facebook as a teaching tool on the motivation level of my English class.This study will help me in developing clear understanding of such a strategy which may help my students to better participate in English reading and writing tasks.... All these are clear signs of little motivation to read and write English. On the other hand, (Littlewood, 2001) have stated that traditional teaching techniques cannot motivate Hong Kong ESL students to have higher participation and motivation in reading and writing English. Further, several studies indicate that despite a variety of teaching techniques including audio-visual have been used in Hong Kong to Teach English as a second language, predominant teaching method is lecture( (Melanie & Warhurt, 2000). Roman-Perez (2003) have described that incorporation of interactive technology reflrcted positive impact over the motivation level of the students for reading English. And I know that all of my students are using Facebook to be in contact with each other. Further, in current Web 2.0 scenario, Facebook has top ranking in SNSs (Kazeniac, 2009). Thus I assume that using Facebook as a teaching tool in a creative way can increase motivation and participation level of my ESL students. 4 . Literature Review: In order to implement my this idea of using Facebook as a teaching tool, I embark on reviewing relevant literature from five dimensions including motivation to learn, motivation to read and write, motivation to learn English among Hong Kong students, technology and motivation to read and write, and finally ,using Facebook as a teaching tool. 4.1. Motivation: Motivation is considered as a prompt and energizer in all fields of life (Mangal, 2002). It may be defined as the force that accounts for the stimulation, selection, direction, and continuation of certain behavior. Literatures on human psychology and on education have extensively discussed human motivation and student motivation in details. Similarly, majority of the educationists

Function Argument Essay Example for Free

Function Argument Essay Aristotle first asserts that happiness is an ultimate good that is both complete and self-sufficient. 2) The ultimate good for a thing is its ability to complete its function. (3) Human being’s must have a function beyond an occupation in society such as a potter or painter because the ultimate human good must be all encompassing. So the function of a human being cannot specifically be being good at any one position or task. The human function cannot involve just growth because that is essentially the function of plants, and a humans function must be unique in itself. 5) Aristotle claims that because animals and plants cannot reason, a human being’s function must have something to do with rationality, the part that involves our soul. (6) Lesser goods like wealth all are meant to lead to happiness, this rises from the first premise that the ultimate good must be self-sufficient. (C) Therefore he concluded that the human function is the completion of a task (the activity) that involves the soul (not the body), and leads to doing what is ultimately the most virtuous or excellent thing to do. The human function is the activity of the soul in accordance with excellence or virtue. I disagree with Aristotle’s conclusion because I believe premise 4 and 5 are false. He asserts that a human being and a plant cannot have the same functions. Here I think there is a flaw in his logic, Aristotle makes an unreasonable jump in what a person should do and what a person has to do. Humans may have simply evolved from a cell like any other animal, which would suggest that completing our base physical goals, surviving and reproducing, is the human function. Yes because we have evolved further and our capacity for reason is greater then say chimps or dogs, we have a deeper understanding of morality and virtues. Yet there is still a distinct difference between what we should do and what we have to do. I also disagree with the 5th premise because I do not believe reason is a virtue only found in human beings. Animals like gorilla’s and elephants have all been shown to show compassion towards other beings, even those not within its species. Aristotle’s conclusion suffers from these false premises. He makes the assumption that doing something good is the same as being good and this is not true. What something has to do, its function, does not necessarily equate to what something should do. Aristotle draws on the premise that animals cannot reason. While I believe there is a valid argument in terms of the distinction on a human’s depth of reason and an animal’s understanding of it. I believe the distinction lies in a more complex understanding rather then a complete lack of reason. I disagree with these two premises.

Truth and Fiction in Truman Capotes In Cold Blood Essays -- In Cold Bl

How In Cold Blood Capote Desensitized Our Ability to Differentiate Between Truth and Fiction.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚        Ã‚  Ã‚   Reading In Cold Blood brought me a new literary and psychological understanding. I realized what such a heinous murder would do to a town like Holcomb, Kansas. I always took my childhood for granted; nothing bad happened in our town, nothing equal to the ugliness of the Clutter murder.   After rereading In Cold Blood, I read every piece of literary criticism on the book as I could find.   I began to consider the impact of Capote on today's based-on-fact books and movies. My goal was to discover whether the blurring of the line between truth and fiction has befogged how we, as readers and viewers, differentiate between truth and fiction.    What I learned (or didn't learn). Wendy Lesser, in an article for the Los Angeles Times, wrote of her interest in murder in literature. She went so far as to teach a literature class at UC Santa Cruz on murder. The class focused on works of fiction based on true facts (books that Capote would have said were non-fiction novels), books such as Norman Mailer's The Executioners Song, Joan Didion's The White Album, and Capote's In Cold Blood (par. 13). At the end of the semester, one of her students said, " 'I've really enjoyed this course, but I'm worried that it's hardened me. I mean, I don't know how seriously I take murder anymore'" (par.15). Lesser replied that by looking at murder as art, you move away from the seeing it as murder (par.16).    Truman Capote claimed to have invented a new type of literature with In Cold Blood, the non-fiction novel (Plimpton, par 2).

Comparing Fermentation Rate of the S. Cerevisiae Yeast in the Presence of Mgso4, Naf and Sodium Pyruvate

Syl Rogers Bio 210 Comparing Fermentation Rate of the S. cerevisiae Yeast in the presence of MgSO4, NaF and Sodium Pyruvate Hypothesis In the fermentation of rate of yeast, S. Cerevisiae, there will be a higher/ faster rate of ethanol production, However, using catalytic enzymes would make the rate more faster, and MgSo4 will have a higher rate of CO2 than that of NaF and Sodium pyruvate as it act as a more better catalytic enzyme than the others. Methods Preparation of Tubes A solution of yeast and glucose was prepared with different concentration of enzymes.In All the tubes water, 0. 3M glucose and yeast was placed; with the exception of some tubes in which 0. 2M MgSo4 and 2. 5mL and 1. 4ML 0. 2 NaF was placed respectively. In another tube was placed both MgSO4 and NaF. The different solutions were prepared and placed in separate tubes for the experiment. A 45oC water bath was setup to be used for the fermentation process. Data acquiring The tubes were placed in the water bath. A s top watch was used which aids in determining the reaction time.After Every 15 min, data was collected from all tubes by measuring the amount of CO2 being produced. This process continued for a total of 75min allowing enough time for Fermentation to occur in all tubes. Result For the first 15min, In the tube containing 8. 5mL water and 2. 5mL yeast only, the rate of the reaction was 0mm/min whiles the tube with the glucose has a rate of 233. 864mm/min. This is followed by the tube containing 2. 5mL of MgSo4 which has a rate of 165. 8573mm/min. The tube containing the MgSo4 and NaF has a rate of 69. 5mm/min which is followed by the 1. 24mL NaF tube that has a rate of 40. 63mm/min followed by 2. 5mL NaF tube which has a rate of 31. 08mm/min which was the lowest. After 30minutes, the tube containing only water and yeast has a rate of 0mm/min whiles the tube with the glucose has a rate of 208. 97mm/min. This is followed by the tube containing the MgSo4 which has a rate of 174. 1137mm/min . The tube containing the MgSo4 and NaF increased to a rate of 169. 59mm/min which is followed by the 1. 24mL NaF tube that has a rate of 57. 77mm/min followed by 2. mL NaF tube which has a rate of 35. 08mm/min which was the lowest. After an hour of reaction time, the MgSo4 and NaF tube has increased to a rate of 193. 17mm/min which is followed by the glucose tube with a rate CO2 rate of 176. 52mm/min followed by the MgSO4 Tube with a rate of 171. 73mm/min. The 1. 4mL NaF tube has increased to 61. 68mm/min followed by the 2. 4mL tube which was the lowest with a CO2 rate of 31. 31mm/min. For the final 15min of the experiment, the glucose tube has a rate of 176. 48mm/min followed by the MgSO4 and NaF tube with a rate of 169. 7mm/min. the MgSo4 tube has a rate of 157. 40mm/min which is followed by the 1. 24NaF tube with a rate CO2 rate of 57. 46mm/min followed by the 2. 5mL Tube with a rate of 29. 34mm/min which was the lowest CO2 production rate. Fig 1: Rate of CO2 production in the f ermentation of Glucose by S. cereviae Discussion: The fermentation of glucose by S. cerevisiae, which yields equal molar amounts of carbon dioxide and ethanol, showed higher production levels of carbon dioxideunder controlled conditions than any other implying the same for production of ethanol.Fermentation affected by a magnesium sulfate solution ranked second in carbon dioxideproduction while sodium fluoride yielded the least amount of carbon dioxide. These results suggest that magnesium has a positive influence on the production rate of carbon dioxide during the fermentation process and that the control contained an amount of magnesium that was neutralized by the presence of the fluoride anion. Though mean production was lower for the magnesium sulfate solution than the ontrol, a few specific results overlapped suggesting the addition of magnesium sulfate had no affect for those instances. A lower mean value for the magnesium sulfate solution suggests either that the fermentation process was supersaturated by magnesium or that the sulfate anion adversely affected the production of carbon dioxide. Further experimentation should be performed to determine the affects of magnesium sulfate in comparison to other magnesium and non-magnesium containing salts such as calcium sulfate or magnesium chloride to determine which ion has the greatest affect.Unknown variables such as the age of the S. cerevisiae samples may have affected the outcome of this experiment. Verification of S. cerevisiae batch age would allow for additional experiments to determine whether magnesium supplementation affects yeast of a certain age differently than that of another. Additionally, the experimental test tube/vial container allowed for some of each solution to be pushed out of the experimental test tube as the level of carbon dioxide increased.Further experimentation should utilize a better method of measuring the production of the entire original solution, not a fraction of the soluti on as a function of time. An alternative would be to attach a balloon to the tip of the solution-filled test tube, measure the diameter of the balloon, let an hour elapse and then measure the diameter again to determine carbon dioxide gas production. Decreased carbon dioxide production levels for S. erevisiae in the presence of a sodium fluoride solution suggest that an absence of available magnesium during fermentation results in an inefficient fermentation process; some level of magnesium is required in order for the process of fermentation to operate at maximum efficiency. Additional magnesium does not guarantee a faster or more efficient means of fermentation/ethanol production and can have an adverse affect on the fermentation process.

Performance Appraisal as the Most Flawed of all Human Resource Management Practices Free Essay Example, 2500 words

What remains to be seen is the fact that employers need to come up with certain strategies and devise ways and means through which their success could be envisioned in a proper way. The performance appraisals seem to be dysfunctional in nature and hence the remedy must be found at the earliest to plug the gap (Catano 2007). What makes the performance appraisals as flawed in essence is the fact that they have not been able to deliver value both for the sake of the organization as well as for the employees themselves. This means that they have been nothing short of being absolutely chaotic in existence and something somewhere needs to be done so that sanity can prevail within the relevant ranks. The flaw stems from the fact that the employees feel a sense of negativity with regards to these performance appraisals. They think that this will eventually bring them in the light of being non-workers, who are unable to deliver value for the sake of the organization, which is absolutely wron g in its disposition and should not be thought of as such. We will write a custom essay sample on Performance Appraisal as the Most Flawed of all Human Resource Management Practices or any topic specifically for you Only $17.96 $11.86/pageorder now The performance appraisals are basically coined so that the employees can derive value and thus gain a leaf out of the book of the human resources management. They can learn that the best way forward within an organization is to show that they work to best effect within it and that all their actions, behaviors and manifestations are in line with the codes and policies as issued by the human resources management (Sulsky 1998). The human resources management, therefore, takes the mantle of the organization and does all that it could so as to be the lone savior for its eventual success within the lengths and breadths of the company. If the HRM is not doing its job properly, then this can easily mean that there are certain shortcomings which need to be plugged in at the earliest. What one understands from this is that the performance appraisals act as the savior under such circumstances.

Attack Fall of the Twin Towers - Free Essay Example

Sample details Pages: 5 Words: 1565 Downloads: 9 Date added: 2019/08/15 Category History Essay Level High school Tags: 9/11 Essay Did you like this example?   9/11 is a tragic day that will forever live in infamy, just like Pearl Harbor Introduction   As the new century began, most people were filled with hope that it was a dawn to a new beginning. But little did they know that the future would not only give them good, but also bloodshed. On September 11, 2001, it was a normal work day at the World Trade Center, filled with about 3000 people who were dutifully doing their job. Suddenly they felt a rumble in the distance and thought it was an earthquake. But before they could figure out was going on, two planes hijacked by terrorists, which were filled with about 100 innocent people, crashed into either side of the building and caused it to collapse, demolishing the once 110-story twin towers and ending about 2,700 innocent lives. Don’t waste time! Our writers will create an original "Attack Fall of the Twin Towers" essay for you Create order Background   There is always a twisted reason in warped minds for these types of terror attacks. The Al-Qaeda organization, the terrorists behind the 9/11 attack, were led by an evil man named Osama Bin Laden. However, Bin Laden, unlike any other terrorist whose motive was to kill to spread religion, wanted to have revenge against America. He had wrongly made up his mind that during the Persian Gulf War (1990-91), the Americans decided to launch a war that collaterally killed Iraqi children and massacre fleeing Iraqi soldiers from Kuwait for the purposes of installing a hedonistic and cruel Kuwaiti dictatorship. He sought to avenge the Gulf War casualties, without realizing that the war was started by the unprovoked Iraqi invasion of Kuwait and the wanton killings of thousands of innocent Kuwaiti civilians by Iraqi troops. He also demanded that American peacekeeping soldiers leave Saudi Arabia after the Gulf War or face the consequences. Bin Laden used religious texts to exhort his supporters to attack Americans until his stated grievances are reversed. How the Attacks were Planned and Executed The idea for the 9/11 attacks came from his sidekick Khalid Sheikh Mohammed, who first presented it to Osama bin Laden. They funded and sent some of their followers to take flying lessons in California, Arizona, Minnesota and Florida. They also trained in using weapons and learned to speak English, to blend in while living in American society. They divided themselves in terror cells of 4 to 5 individuals called â€Å"sleeper cells†. They bought plane tickets on four large commercial airplanes with long flights because they would be heavily fueled. Early on the morning of September 11, 2001, 19 of Bin Laden’s followers became hijackers and took control of four commercial airliners. The four flights that were hijacked mid-flight, along with hundreds of innocent passengers and flight crew-members on board, were: American Airlines Flight 11: a Boeing 767 aircraft from Boston to Los Angeles. United Airlines Flight 175: a Boeing 767 aircraft from Boston to Los Angeles. American Airlines Flight 77: a Boeing 757 aircraft, from Washington DC to Los Angeles. United Airlines Flight 93: a Boeing 757 aircraft, from Newark to San Francisco. In all four cases, the hijackers attacked the unsuspecting flight crew members and forcibly took control of the cockpits by using violence and weapons they had smuggled on board. Their targets were the most prominent and strategic buildings that underlined America’s financial strength and military muscle. The terrorists flew the first three planes into New York City’s World Trade Center’s North Tower and South Towers, and the Pentagon in Arlington, Virginia (near Washington DC). In the case of the fourth aircraft, as heroic passengers and crew fought back and attempted to subdue the hijackers, the hijackers intentionally crashed the aircraft into a field near Shanksville, Pennsylvania. It is believed that their intended target was either the Capitol Building or the White House in Washington DC. Human Casualties and Concomitant Tragedy In New York, the World Trade Center’s North Tower, South Tower and a smaller building (â€Å"7 WTC†) collapsed after a few hours, due to fire-induced structural failure, killing or trapping thousands of innocent people who worked in offices in these buildings. The large amount of fuel in these airplanes accelerated the destruction of these historically remarkable buildings. As a result of the attacks on these Twin Towers on 9/11, a total of 2,763 people died including 2,192 civilians, 343 firefighters, 71 law enforcement officers and 147 passengers and crew on the airplanes. The Pentagon’s west side sustained significant damage with 184 casualties, including the passengers, flight crew along with the military personnel and civilians inside the building. In the case of the fourth aircraft, all the 40 passengers and flight crew members died in the crash in the field, but the heroism of the passengers saved the lives of many hundreds of potential victims who worked in the intended targets (the Capitol Building or the White House). To summarize, the 9/11 terror attacks killed 2,996 innocent people, injured over 6,000 victims, and resulted in at least $10 billion in infrastructure damage in America’s two most significant cities – Washington DC and New York. Such a large, coordinated series of terror attacks had never ever been carried out on American soil, since Pearl Harbor. Television channels replayed the horrific visuals of the airplanes hitting the Twin Towers and Pentagon, and the subsequent collapse of the burning towers. The only silver lining was that at least 12,000 people were able to escape from the burning Twin Towers during the next 102 minutes after the terror attack, unlike the 2763 people who perished at Ground Zero. Hundreds, if not thousands, of shocked eyewitnesses and survivors in New York and Washington DC have described the horror of watching the airplanes smash into the buildings and the flames, heat, smoke, dust and debris that rained down on them. Panic stricken office employees ran down many hundreds of steps at the Twin Towers amid blinding smoke and heat, while being helped by brave firefighters before the buildings collapsed. Others who were trapped in the upper floors of the Twin towers plunged to their deaths from windows while attempting to escape the blazing inferno. Many books, articles and interviews provide significant insight into the tragic history of 9/11 and contain vivid eyewitness accounts of survival from firefighters, economists, lawyers, hotel guests, hotel employees and business travelers. Firsthand accounts of survival, tragedy, and heroism drawn from hundreds of interviews underlined incredible stories of bravery, courage and overcoming unbelievable odds. Other books described the pain and trauma of the victims’ shell-shocked families, especially orphaned children, who were forced to journey through shock, pain, birth, and rebirth in the aftermath of a great tragedy. Even the 9/11 survivors and their families tried to cope with this unexpected tragedy, while being tossed into a storm of bureaucracy, politics, patriotism, mourning, consolation, health issues, suffering and parenthood. Aftermath of 9/11 The post 9/11 resilience of American society is showing positive results. The World Trade Center is being rebuilt at the same site in New York city. The damaged western section of the Pentagon was rebuilt and occupied within a year of the attacks. There is remarkable alertness about terrorism among the people who see heightened security at airports, important buildings, bridges, malls and other crowded places. But the personal losses of their loved ones and financial losses to the US economy may never be recouped. As a result of the 9/11 terror attacks, many countries were shaken out of their complacence and governments across the world have passed legislation to combat terrorism. Many memorials and vigils were held across the world for the 9/11 victims. Many countries became allies of the United States and showed solidarity with the 9/11 victims. The global community has joined the war on terror. Several top Al Qaeda terrorists, including Osama bin Laden, have been neutralized. The Taliban regime in Afghanistan and the Iraqi dictator Saddam Hussein were overthrown by US and NATO troops. The world is becoming more alert to terrorism than ever before, and many countries are cooperating with each other to foil terror attacks before they are committed. Thousands of terrorists have been killed or arrested worldwide, in the nearly two decades after 9/11. On the other hand, newer terrorist groups have emerged to take the place of Al Qaeda.   Many countries, especially in the Middle East, have unfortunately slipped into chaos and civil war due to widespread sectarian terrorism. After 9/11, there have been thousands of terror attacks, big and small, on civilians and security personnel in nearly 100 countries across the globe. New bands of terrorists have brutally targeted innocent people at shopping malls, airports, streets, trains, buses, schools, colleges and places of worship in six continents. Other terror attacks have been thwarted by alert authorities with the help of people. As law enforcement and intelligence personnel grapple with this boom in cross-continental terrorist networks, the terrorist groups are radicalizing impressionable youth by using the internet and YouTube for recruitment and religious brainwashing.   This has led to an increasingly voluble debate, be it in the media, politics and in society, about the root causes of terrorism and how to tackle this problem. Lessons to learn from 9/11 The twenty-first century has lessons to learn from the 9/11 tragedy and the subsequent triumph of humanity.   If the world succumbs to this growing cancer of terrorism, then all the civilizational gains made by humanity over several millennia may be lost forever and we may end up in a veritable stone age. But if humanity pulls the world back from the brink and discovers the panacea to everlasting peace, then a catastrophe like 9/11 will never occur again in our lifetimes, which will make the world a safer place for our future generations.
