Green Construction Essay

The Earth has been around for billions of years and people only a couple of millions of years. Yet, people have made such a huge impact on the Earth. In the course of mankind’s existence, people managed to make advancements that defined the way life is being lived today. However, there are prices to pay for all of the comforts that people are now experiencing. It has been said that there is only one Earth and people must do all they can in order to preserve it. Campaigns have been launched to ensure that life on Earth and the Earth itself can be sustained so that the future generations can still enjoy it. Even prominent people have taken an active role against human activities that contribute to the degradation of the blue planet. One of the activities said to be closely linked with the environment, thus directly affecting the latter, is construction. According to the Urban Environmental Management website, a number of natural resources are being consumed when construction takes place, i.e. land, water and energy (Srinivas, 2007). This being the case, ensuring that the negative effects of construction on the environment be minimized is of utmost importance. Focusing on this issue, the UEM website provided key information about the topic. It managed to define what green construction is. It was also able to highlight the importance of sustainable development, which is a concept closely related to green construction. The information posted on the website is relatively comprehensive. Navigation is not going to be a problem since the layout of the page specifically relating to green construction is simple and user-friendly. If an internet user is new to the concept of green construction, then visiting UEM’s website is going to be a big help in understanding the basics behind the concept. The information on the website ranges from awareness, assessment to action, making the website truly a good find on the internet. Reference: Srinivas, H. (2007). Introduction to Green Construction.

Sedimentary rocks in Pakistan range in age from Precambrian to Miocene i. e from oldest to youngest on the geological time scale form 542 million years to latest. Luckily for geoscientists all of them are exposed in different parts of the country. Lithologically they constitute sandstone, limestone, shale and mixed lithologies of them all. These rocks are exposed all along the mountain ranges from Islamabad in north to Karachi in the south. Igneous rocks are exposed north of Peshawar or only at Nagarparker in the southeastern corner of the country.You better study ‘Stratigraphy and historical geology of Pakistan' by Kazmi and Abbasi (2008), which will provide you a full knowledge about the rocks in Pakistan. ‘Geology and tectonics of Pakistan' by Kazmi and Jan (1997) also gives details of distribution of ores and minerals in different parts of the country. Names [de] Mergel [en] marl Description Marl is a sedimentary rock made of clay and limestone, which belongs to the f amily of pelitic rocks (clays

Bacteria Growing

Bacteria grows everywhere and there is no way to hide from it. Bacteria can be harmful, but most are not. They're strategies to help kill bacteria on human skin. The answer is soap. It doesn't matter if the bacteria is from its natural source or a petri dish. There is always a cleaning substance out there ready to kill the bacteria that grows on our body and other places in the world. People wonder what soap works the best and why it works the best. Microbiology is a branch of science that deals with understanding bacteria. A great deal of research has been done to figure out what kills bacteria. Scientist at the University of Toronto did research and believe that hand sanitizer works the best (Hall, 2012). Bacteria is everywhere and scientist want to find the best resources to kill it fast and well. Cleaning agents are hard to find, but they are worth it when human hands end up clean. There are many substances that are used to wash your hands, but only some are used to kill bacteria. Microbiology is a branch of science that deals with microorganisms. Bacteria grow when one cell splits into two during a process called binary fission. This can happen in a matter of twenty minutes (How to Grow Bacteria, 2017). Bacteria grow in sets, one becomes two, two becomes four, four becomes eight, and so on (Bacteria, n.d.). Bacteria can be harmful to the human body. That is why it is very important to keep clean. Bacteria can be grown using agar. Agar does not grow bacteria on it's own. Agar is a red algae, that when it is mixed with water turns into a gel. Growing bacteria in petri dishes work better because it provides the nutrients and moisture to help it grow. Bacteria grow better in a moist and warm environment. Usually, water and oil don't mix. This causes water and oil to separate into two different layers. Soap then breaks up the oil into smaller pieces so it can mix with the water.This works because soap has molecules with two different ends. The first end of the soap molecule loves water. Which is called hydrophilic. The other end hates water and is called hydrophobic. Hydrophilic ends will attach to the oil, as hydrophobic ends attach to the water. The drops of oil will then be removed under the running water. Soap causes bodies to be free of dirt and grease (Biology, n.d.). This is an important process when washing your hands. Studies show that hand sanitizer and antibacterial soap work the best. Soap removes soil and germs from hands, while sanitizer evaporates the germs and bacteria found on hands (Kania, 2011). Some people love to use the colorful, smelly soaps that come in a variety of types. Does they really kill germs? Not always. Not unless it contains antibacterial properties. Ethyl alcohol is also effective. Ethyl alcohol kills most bacteria and fungi. When putting hand sanitizer on human hands it takes between 15 and 30 seconds to kill 99.99% of bacteria, after one minute possibly 99.999% of bacteria. In order for the substance to kill that many germs, human hands need to continue to stay wet and let the substance evaporate after being used (Editors Encyclopedia Britannica, 2018). In conclusion, bacteria grows everywhere, any day, and at any time. Bacteria can be harmful to the body, but bodies have immune systems to fight them off. Keeping clean is very important in order to have a healthy body. The delicious smelling soaps are not always the best. Beliefs are that hand sanitizer works the best and kills the most bacteria and fungi, although, some might think antibacterial soap does the trick. Scientist who study microbiology have made important advances in learning how to keep people safe from bacteria. Ethyl alcohol is the most important ingredient to killing bacteria. Always keep clean to keep the harmful bacteria away.

To what extent does restructuring transform corporate market and Essay

To what extent does restructuring transform corporate market and financial performance Discuss using an extended example - Essay Example It plays a vital role in decreasing the stress between debt holders and equity holders due to which they can come up with instant solutions of different problems. And on the other hand it also reduces financial crisis and losses. Financial performance and corporate markets have been transformed through restructuring to some extent, but the degree of transformation is the main question. This question is answered in the following example of a worldwide food processing company â€Å"THE HEINZ COMPANY†. According to Gordon Donaldson, â€Å"We have become so familiar with the phrase financial restructuring in the past decade that we often fail to ask why financial structure became such a battleground for contending agents of change.† (Donaldson 1994, 6) â€Å"H.J Heinz Company† was originated in Sharpsburg, Pennsylvania in 1869. The company was founded by German Henry John Heinz. At that time Heinz was only 25 years old and initially he used to distribute condiments to limited grocers by Horse-drawn wagon. Initially the company’s original name was â€Å"Anchor Pickle and Vinegar Works†. The first product line of the company had only horseradish but later tomato ketchup and pickles were also introduced. In 1874 L.C Noble became the partner of Heinz Company. After their partnership the company’s name changed from â€Å"Anchor Pickle and Vinegar Works† to â€Å"Heinz, Noble & Company† and they moved to a larger headquarter located near Pittsburgh. Their assets increased to 30 acres of Horseradish, 24 horses, 12 wagons, 100 acres of garden and a vinegar factory in St. Louis. In 1875, banking panic and economic chaos forced Heinz into bankruptcy and their business failed. But soon after in 1876, Heinz restructured its company with an aim to repay all his creditors and introduced a new product in its product line â€Å"Tomato Ketchup†. Heinz formed a partnership with its cousin Frederick and brother John. In 1877, their product line further extended

Finance and Growth Strategies - Assignment Example The paper tells that dividends are returns which are paid to the shareholders from the firm’s earnings for their investment in the company regardless of whether the earnings are generated in previous period or the current period. Dividends will influence the capital structure of the firm since retained earnings increase the value of the common stock than debt capital. A firm cannot assume the dividend policy to be irrelevant. In determining the amount to be paid as dividends, the firm should analyze the effect of the dividend policy on the operations of the. However, some financial analysts are of the opinion that dividend policy is irrelevant since it does not change the value of the firm. Investors can adjust the investment portfolios when if their preference is a steady source of income hence they can invest in bonds where the interest payments are certain rather than investing in common stocks where the dividend payments fluctuate. Another argument of the opponents of divi dend payment is that taxation of dividends is higher hence capital gains are more preferable by investors. They propose that the firm should reinvest the earnings which will ultimately increase the value of the firm hence increasing the share value. The firm should utilize its earnings in undertaking more investment projects, repurchasing the common stock and acquiring more profitable companies thus increasing the market value of the common stock... The firm is also supposed to make a decision on the timing of the payment of the dividends whereby interim and final dividends can be paid from the earnings of the firm (Khan 2004). The board of directors is supposed to make a decision on the amount to pay where a constant dividend pay out ratio or fluctuating dividend pay out ratio may be implemented by the firm. The firm may also adopt a residual policy on the payment of dividends. The dividend policy has to take in to account several practical considerations which include the following (Khan 2004). Long term financing decision The dividend policy can be termed as a financing decision when retained earnings are considered as cheap source of finance. The dividend policy should consider the investment opportunities which are available (Khan 2004). If the firm ahs viable investment opportunities which exist, the dividend policy which is adopted should be residual dividend decision where dividends are paid only after enough funds have been allocated to the viable investment opportunities (Khan 2004). Retained earnings are a cheaper source of funds since they do not involve the floatation costs. Payment of cash dividends would reduce the funds available for the long term financing decisions when the firm may not have other sources of finance (Harold 2009). In this case, the firm may decide to pay bonus shares as dividends to the stockholders and invest the retained earnings in other profitable opportunities since the share value of the stocks increase with the increase in the value of the firm (Harold 2009). Financial needs of the firm Retained earnings of the firm are cheaper source of finance for reinvestment purposes. If the internal rate of return of the firm

Analysis of news presentation of academic research Essay

Analysis of news presentation of academic research - Essay Example However, this is not the case with news research, as there is no particular detailed research undertaken to ascertain the authenticity of the information presented. Two articles, scholarly research and news media research, addressing the same issue, are very different. While the scholarly article reports about the actual study conducted, the news article is a report about the scholarly research report. It is thus less detailed and does not have as much information as the actual article. In view of this, in this paper, I will analyse two articles, both addressing the same issue, mobile phone advertising, will show the differences between the two articles. The article, â€Å"High stroke and heart disease link to living close to airports† is a news media report on the actual journal article, â€Å"Aircraft noise and cardiovascular disease near Heathrow airport in London: small area study† by Hansell,, et al. (2013). The report points the objective of the actual study, with out giving further details. In fact, there is little relationship between the information contained in the news article and the scholarly researcher. The author, using the thesis of the study that there is a positive relationship between aircraft noise and higher rates of stroke and heart diseases, reports on the outcomes of the study. ... from mentioning the study to support his story, the author uses little information, indicating that his was simply a news item with minimal scholarly intentions. The article, â€Å"Aircraft noise and cardiovascular disease near Heathrow airport in London: small area study† is a report by the researchers, Hansell, et al. (2013). The study points out that there is a high likelihood of people living close to airports to develop problems such as the stroke, coronary heart disease, and cardiovascular disease. The researchers, in order to prove the hypothesis of their study, conducted an analytic case study on neighbourhoods exposed to varying levels of aircraft noise related to Heathrow airport. The article sought to compare the hospital admission rates for people suffering from cardiovascular disease in this area. Using standard noise metric, the A weighted equivalent (Aeq) sound pressure level; the researchers established the relationship between people’s exposure to airpl ane noise and the increased risk of suffering from these diseases. The researchers, using a qualitative research technique, carried out an analysis comprising of 12 London boroughs and nine districts west of London. These were the groups with a high risk of exposure to noise emanating from Heathrow airport. For an article to qualify as a scholarly article, a research methodology should support the assertions made by the author. There are two main methods used in research, i.e. qualitative and quantitative, which researchers use while conducting their research, most significantly on data collection. According to Creswell (2003), qualitative research method (traditionally used in social sciences, but currently applied on market research) aims at gathering adequate information about an issue or an

Extended Definition Essay Example | Topics and Well Written Essays - 750 words

Extended Definition - Essay Example The carburetors perform the same basic objectives as the fuel injectors. The difference however is how the two work. The carburetors supply fuel to the engine through a process of suction where the system sucks in air to allow fuel to enter. Once air is in, a vacuum will be created in the pipes connecting the fuel tank and the engine. The pressure gradient that exists between the chambers of the fuel tank and the engine is what forces the fuel to rush into the engine. The fuel injectors on the other hand avail fuel to the engine through a pumping mechanism (Cramer and Hoffmann 210). The system will pump in the fuel under pressure straight to the engine upon acceleration. This mode of fuel transfer is more effective than the former done by the carburetors. This explains why carburetors are being faced out in modern assemblies to pave the way for the more efficient injectors. The injection process also has another benefit in that it allows the driver to regulate the volume of fuel getting to the engine from his/her seat. This is unlike the former case where the amount of fuel getting to the engine depended on the speed limit gained earlier while driving and gained gradually. The injection system benefits the driver in so many ways that the carburetor could not. This include the ability to control fuel burns during high speeds and the ability to carry out quick throttle transitions such as change of gears and braking work (Cramer and Hoffmann 20). The driver is also able to regulate the fuel consumption in the car. There is also the advantage of smoother transitions such as smooth change of gears. Normally when the vehicle engine is cold in the morning for instance, there is need to perform a choke process in order to start the car. The presence of the fuel injector will eliminate this disturbing process from the driver’s task making it easier to quickly warm and start the engine. The

Relationships Between Nursing, Health, and the Policy Processes Article

Relationships Between Nursing, Health, and the Policy Processes - Article Example This is because several laws and policies within the country support abortion. The woman also indicated that her health was in danger because the pregnancy affected her psychological well-being because she conceived under duress. The policy that best typifies the case study is Access to Abortion Services that give women rights to abort. This right allows women to access abortion services, as well as support within health care units. The act also creates access routes, and prohibits derogatory actions such as harassments. Some of the access routes include the health care facilities, physicians’ offices, and other service providers (College of Registered Nurses of British Columbia, 2013). Additionally, individuals receiving abortion services and issuing financial and emotional support are protected. The legalization of abortion has been controversial in the United States for the past 200 years making it difficult for the process to enjoy the protection of the law (Simmonds, 2013). Currently, women in the United States have legal abortions right granted throughout the pregnancy period. Furthermore, the women have the right to abort in almost all situations especially after Supreme Court announced the inc orporation of abortion rights into the constitution. This implies that any lawful barriers that will hinder the females from having abortion are unconstitutional (Abort73.com, 2009). This policy involves the nursing process because the service providers include the nurses who offer the abortion services and care based on the provisions of the act. This means that it is illegal for nurses to refuse to give abortion services to females especially when the circumstances are justifiable. I supported the nurses’ decision in the case study. This is because the elements of the abortion policy contradict religious practices. According to my religion, abortion is sin because it constitutes murder.

A Short History Of Singapore History Essay

A Short History Of Singapore History Essay Numerous evidences had been uncovered, and reports and archaeological findings especially, certainly suggest that Singapore was largely strategic between the period of Temasek, in 14th century, and late 17th century. However, to conclude that Singapore was hence always strategic would probably be too much of an overstatement. This essay will discuss Singapores strategic significance, with the support of these evidences, during the different time periods. During the 14th century, trade was already ongoing between the West, South Asia and East Asia. The Melaka Straits was crucial for traders to sail to and fro the Indian Ocean to the South China Sea. Sailing in the past depended on wind direction, thus ships had to stop in Southeast Asia (SEA) to wait for a change in wind direction to bring them towards either China or India  [1]  . Singapore was hence a strategic port because she was located in SEA and along Melaka Straits, making it a convenient stopover hence the central of international trade  [2]  . Bits of celadon (from China), Chinese coins  [3]  , fragments of stoneware (mainly from Guangdong and South Fujian) and earthernware (from Sumatra, Java and Borneo)  [4]  and under-glazed blue and white stem cup (more expensive of porcelains from Jingdezhen during Yuan Dynasty)  [5]  recovered support the above claim as they suggest extensive trade links Temasek had with China and SEA, and that its inhabitants, espe cially the wealthier ones inhabiting Fort Canning, were able to afford the more exquisite products of Jingdezhen  [6]  . Temasek then, was able to attract maritime trade by providing unique products that rival ports were unable to supply. Recorded by Wang Da Yuan in Daoyi zhilue  [7]  , Temasek supplied indigenous products like hornbills casques of excellent quality. Found only between north of Malay Peninsula and South of Borneo, traders can only lay their hands on it at Temasek or Palembang  [8]  . Though Lakawood was in abundance, Temasek was one of the five ports that offer those of middle-quality  [9]  . Celadon, white wares and stonewares uncovered at Riau Archipelago, dating back to the period of Temasek, had patterns and craft similar to those imported from Temasek  [10]  . Furthermore, the origin of glassbeads of Riau Archipelago and Temasek should be identical given similar compositions  [11]  . Hence, Temasek probably served as a collection centre and an entry to export for Riau Archipelago  [12]  . In this case, evidences do suggest that Singapore was prospering and had an influence on regional economy and was thus strategic. During the 15th to 17th centuries, though Singapore declined slightly when Temasek was relocated to Melaka, fragments of under-glazed blue porcelains found at Kallang River  [13]  , and Portuguese maps which indicate the presence of a shahbandars office  [14]  , as elaborated in (b), suggest that she retained some of its strategic significance as a port by maintaining some trade with China. As mentioned, being one of the strategically situated along the Melaka Straits, the power that was able to erect a strategic dominance around the waters around Singapore would be advantaged in terms of security and economically. The Dutch had wanted to destroy Luso (Portuguese-Spanish) monopolies in SEA when they first started attacking Portuguese trading ships around Singapore waters and declared war with the Portuguese when they raided Santa Catarina and auctioned off its products  [15]  . This saw the naval battles between the Dutch and Johor Sultanate, and Portuguese and Acehnese in the early 17th century and gave rise to the considerations of fortifying Singapore by both powers  [16]  . Jacques De Coutre proposed to build forts at the east coast of Singapore and Muar River estuary and station a naval fleet at Sentosa to protect Portuguese trading ships from the Dutch  [17]  . Dutch had the same places in mind for their fortification plans  [18]  . Till this point , the Dutch and Portuguese reports do suggest that Singapore was strategic. However, the plans never realised, which made us rethink if Singapore was really that strategic after all. Singapores strategic significance took a turn in the 18th century. There was not much evidence to prove this period of time, but by referencing to my contextual knowledge, we know that the Dutch shifted their focus from the Melaka Straits to the Sunda Straits, Portuguese diverted their trade to Japan having difficulties trading in the Melaka Straits and Johor Sultanate relocated their capital to the Lingga Archipelago, shifting the maritime silk road southwards  [19]  . Singapore lost its value with the declination of Melaka Straits and was abandoned. She no longer held any strategic significance to participants of the maritime trade. Perhaps it is precisely that not much evidence was found that dates back to this period of time that it suggests that trading activities in Singapore was kept to its minimum. Moreover, no coins or porcelains were uncovered that dates beyond the Song and Yuan Dynasty, and the Ming Dynasty respectively  [20]  , further supporting my contextual kno wledge. It is evident that Singapores strategic significance changes with time, depending on human-related factors such as politics and economics, and hence is relative. The evidences may seem to imply that Singapore was always strategic, but when viewed from another angle, they can also suggest otherwise as stated in the previous paragraph. Therefore to say that they suggest that Singapore is always strategic may be a little too extreme. b. In light of this evidence, should Singapores history from 1511 to 1819 be written as (1) little more than a sleepy fishing village? (2) a declining but still thriving emporium astride hotly contested strategic waters (3) part of the Johor Sultanate?  Ã‚  Please explain your preference. From the 15th century to 17th century, Singapore was a (3) part of the Johor Sultanate, but she was (2) a declining yet thriving emporium astride hotly contested strategic waters between the 16th and 17th century. It was only during the early 18th century that trade in Singapore started dipping, and she was perceived by the British as a sleepy fishing village when they stepped ashore in 1819. Hence, (1) little more than a sleepy fishing village suitably describes Singapores history between this period as it is a broader title and thus encompasses both (2) and (3), and the reduction of importance of Singapores port resulting from the declination of the Melaka Straits during the 18th century accounts for Singapore being a sleepy fishing village. When Singapore was (3), trade was still ongoing though insignificant compared to its Temasek period. Excavations on the north bank of Singapore River, where a settlement was once present, and Kallang River revealed fragments of ceramics and under-glazed blue porcelains with designs dating back to the rule of Ming Emperor Wanli (1573 to 1620)  [21]  . Similar findings in Johor Lama and Johor Shoal imply that the findings in Singapore belonged to the Johor River trade controlled by the Johor Sultans  [22]  . Some may suggest that these pieces might have been disposed into the Kallang River when ships stopover for supplies because they broke during the voyage, and not because of trade present in Singapore  [23]  . This may be true, however, according to two Portuguese maps, a shahbandar of the Johor Sultans office was featured on the southern coast of Singapore  [24]  , proving the above conjecture wrong and showing that trade at the Kallang River was flourishing to the extent it needed a shahbandar to run it. This also indicates that Singapore then, was continuing some degree of trade with China, showing that she was (1). As mentioned, trade was also falling, compared to its Temasek period, as during this time, Melaka was the main port for international trade  [25]  . Singapore then, supported Melaka by providing goods from herself for Melaka to export. An example being blackwood, which was brought from Singapore to Melaka, and then bought in bulk by Chinese traders  [26]  . (2) may now seem to be plausible at this point in the essay since Singapore was a declining yet thriving emporium, and evidence show that its waters are hotly contested for between the Dutch and Johor Sultanate, and the Portuguese and Acehnese, and Singapore was seen by both as strategic to build a fort to achieve their individual aims as mentioned in (a). However, one may wish to note that Singapores waters may not be that strategic after all. In 1613, Aceh successfully attacked Batu Sawar as she was upset about the signing of the peace treaty between Johor Sultanate and Portuguese, uncovering the vulnerable position of Singapore waters, rendering it no longer strategic  [27]  . Moreover, when Melaka Straits lost its importance to Sunda Straits in the late 17th century, Singapore was neglected and declined over the 18th century  [28]  . Its waters were no longer contested and the issue on it being strategic or not became irrelevant. A village of Orang Lauts and Malays, not being much of a deal, were all that were left in Singapore. Melaka Straits was filled with pirates and Singapore, lying on the Straits, was hence seen as a sleepy fishing village by the British when they landed in the 19th century  [29]  . (2) does not take into account these happenings, thus it is flawed in describing Singapores history. In conclusion, (1) best describes Singapore history as it accommodates the period when Singapore was (3), when trade was active though declining, the period when it was considered strategic and its waters contested by the Dutch and Portuguese, up to the period when British founded Singapore as a sleepy fishing village due to the decline of Melaka Straits. (2) was unsuitable as mentioned above, and (3) seems to be an understatement as Singapore was more than just part of the Johor Sultanate.

†REFLECTION Monitoring and Ensuring Quality Care

– REFLECTION Monitoring and Ensuring Quality Care Introduction The purpose of this paper is to reflect on a recent personal experience of patient care, which enabled me to achieve a module 9 competency, Actively seeks to extend own knowledge. I will be critically analyzing one nursing practice incident using Boud, et al (1985) model of reflection, (please see appendix 1) which will enable me to monitor and ensure quality patient care in future practice. The nursing incident happened when I was looking after a patient requiring enteral tube feeding (ETF). It is important to note that all confidential information relating to patients, wards, hospitals and professional colleagues has not been included in this paper to ensure ethical practice and adherence to the NMC code of professional conduct, section 5 which affirms that I must guard against breaches of confidentiality (NMC 2008). Reflection is a useful tool for the continuation of professional development among nurses (Somerville and Keeling 2004). The word reflection originates from the verb reflectere which means to bend or turn backwards (Hancock 1998). It is a tool, which unlike text books and videos, does not have a limited shelf-life, it is cost effective, is portable and can be used world wide. Patient Profile The aspect of nursing care I have chosen to reflect on is the care of a patient who required enteral tube feeding (ETF) due to dysphagia a condition in which the action of swallowing is difficult to perform (Unison Health Care 1998). This nursing intervention was essential for a patient in my care, who I shall call John. Please see appendix 2 for Johns past medical history. The Plan of Treatment for John John was admitted to my area of practice six days ago following his CVA. He is receiving ETF via an NG tube as an immediate intervention and is being assessed to see if he is a suitable candidate for a percutaneous endoscopic gastrostomy (PEG) tube which are used as a more permanent form of enteral tube feeding (Holmes 2004). The nasogastric tube is about 22 inches [55.9cm] in length (Holmes 2004) and was inserted into his left nostril down through the pharynx, through the oesophagus and through the cardiac sphincter muscle and into the stomach (Marieb 2001). Food can be administered through the tube directly into the stomach and the swallowing process does not need to take place. The food is administered by a pump that controls the amount of feed given in mls per hour. This description could sound as though ETF is always safe and effective and has no complications. Elia (2001) affirms that ETF is typically safe and easy to administer. However John did experience a number of difficul ties that could have been rectified sooner than they were. On reflection of Johns care it is clear to see (with the benefit of hindsight) that if Johns care was managed differently and if complications were noticed and acted on promptly, his hospital experience could have been very different. 1.) Returning to the experience Problems John faced. John experienced two main complications as a result of ETF. The first was regurgitation of the feed into his throat and mouth and the second was diarrhoea. The rate of the feed had been increased over a period of days to its optimal rate, following the ETF guidelines provided by the NHS trust that I was working in. The infusion was commenced during the night while he was sleeping to allow John greater freedom during the day as he could be disconnected from the pump. The regurgitation happened during the first night that the pump was running at the optimal flow rate. Davis and Shere (1994) report that regurgitation is a common complication of ETF. As a consequence, John had to swallow what had come up into his mouth. The rationale for John to undergo enteral tube feeding was to prevent further weight loss and aspiration which can be caused by dysphagia (DeLegge 1995, Gibbon 2002 and Davies 1999). Aspiration has various meanings, however in this context it refers to the movement of for eign material i.e. fluids or food, into the trachea and further down into the lungs (Unison Health Care 1998). This can occur when the swallowing mechanism is ineffective or impaired. Infection of the lobe of the lung, in which the foreign material has lodged, occurs. This is called aspiration pneumonia (Unison Health Care 1998). Patients suffering from dysphagia are at risk of developing aspiration pneumonia (DeLegge 1995 and Gibbon 2002). ETF was commenced to overcome this risk but now the very intervention that was intended to eliminate the risk has caused an even greater risk of aspiration pneumonia. According to Marieb (2001) there are two stages of deglutition (swallowing). The buccal phase, which is a voluntary action, occurs in the mouth and is the first phase of deglutition. The tongue progressively elevates anteriorly to posteriorly, propelling the bolus through the oral cavity. When the bolus has moved to the base of the tongue, the soft palate is raised, preventing food from being regurgitated via the nasal passage (Davies 1999). The second is the involuntary pharyngeal-oesophageal phase which Davies (1999) describes as a complex sequence of muscular movements. After a CVA the ability to initiate the secondary phase of deglutition can be disrupted resulting in ineffective or complete failure of this phase of deglutition. This short explanation of pathophysiology demonstrates how important it is to know nursing rationales for nursing interventions. Patients suffering from dysphagia can sometimes overcome the problem by eating a pureed diet and drinking thickened fluids, but this depends on the severity of the dysphagia (Stringer 1999). John needs ETF because his dysphagia is too advanced to be overcome by a change in diet. Arrowsmith (1993) recommends that patients who are receiving ETF via a NG tube that are lying in bed, should have their head and shoulders elevated 30-40 degrees during feeding and up to one hour afterwards to minimise gastric pooling and reflux of the feed. This example demonstrates how a simple action can make a substantial impact on the quality of care that they experience. It has the twofold purpose of Impact of the quality of care that they experience. It has twofold purpose of promoting the effectiveness of the intervention and minimises harm to the patient by reducing the risk of aspiration pneumonia. Assessing for signs of aspiration in a patient suffering from dysphagia should always be taken seriously by nursing staff. Stringer (1999) reports that if dysphagia is serious enough it can prevent the victim from swallowing their own saliva. The average person swallows approximately 590 times each day 146 when eating, 394 when awake and not eating and 50 times during sleep (Davies 1999). With the average person swallowing literally hundreds of times each day, patients are at risk of aspirating (on their own saliva) regardless of ETF. Barer (1989) found that over one third of conscious acute stroke patients admitted to hospital had unsafe swallowing. Davies (1999) citing Ellul and Barer (1994) affirms that dysphagia in the first three days after stroke is associated with a five to tenfold increased risk of chest infection during the first week. This is due to varying degrees of aspiration. Aspiration is a potentially fatal complication of ETF. John also experienced three episodes of diarrhoea since starting ETF. John was only provided with a commode which was only dealing with the symptoms rather than treating the cause. No contact was made with the senior house officer or dietician. Furthermore there did not appear to be much concern among the nursing team and there was no discussion or sharing of knowledge between colleagues accept what came from myself. I told my mentor what I had been reading during my reflection time and pointed out some reasons that have been identified as causing diarrhoea for patients receiving ETF. The attitude of my mentor was apathetic, and commented, Hes bound to pick up a bug, give it time, it will pass. This shocked me as Somerville and Keeling (2004) reports that the nursing profession depends on a culture of mutual support, and this was not what I received from my mentor. I wanted to discuss the temperature of the feed, his current medication and the cleanliness in which the feed was prepared and administered. If the feed is too cold when it is administered it can cause diarrhoea (Arrowsmith 2003). Howell (2002) reports that diarrhoea can be the result of ETF but it can also be due to the side effects of medications. Antibiotics can cause the common side affect of diarrhoea (BMA 2001) but John was not receiving any. Diarrhoea in ETF can also be caused through the introduction of bacteria through poor hygiene standards in the preparation and administration of the feed; however the preparation and administration does not need to be performed aspptically. This is only indicated if the patient is immunocompromised (Arrowsmith 1993). My professional knowledge reminded me that I could not dismiss the diarrhoea as a coincidence. If there were nursing interventions that could be used and I didnt use them, I would be failing to provide quality care for my patient. Nurses are responsible not only for their actions but also for their omissions (NMC 2008). I wanted to refer to each others professional knowledge through discussion, and to the ETF guidelines to see if there was a simple cause to the problem that could be rectified before consultation with the doctor or dietician became necessary. I was able to rule out most factors that can cause diarrhoea. This led me to believe that the infusion rate could be too fast. These are the factors that I wanted to discuss with my mentor so I could contact the dietician to seek help from the multidisciplinary team. Gibbon (2002) asserts that stroke care requires the services of a multi-professional te am, working towards an agreed therapeutic plan hence my reason to collaborate with the dietician. 2.) Attending to feelings What did I feel was Positive? During reflection time I was very interested and pleased to find this research to suggest that there could be something that I could do to put an end to the discomfort, distress and potentially disastrous complications of a patient in my care. Many times as a student I have felt that I personally, am not making a great difference to my patients health and wellbeing as I am not working independently, but under my mentor who in general decides on a course of action for our patients. This time I have found the answer from my own research. All that remains is for me to bring this research to my mentors attention and then put the intervention into practice. The patient will benefit, and I will have a great sense of achievement as I will have, in a small way, improved the quality of someones life, accomplishing one of the reasons why I decided to take a career in nursing. Attending to feelings What did I feel was Negative? In response to the apathy that I encountered, I felt disappointed and powerless and undervalued. My original mentor was off on temporary short term sickness due to a small operation and therefore I was allocated another Junior Ward Sister to take her place for the short period of time in her absence. I felt disappointed because my contribution to the care of my patient was not welcomed and that this mentor was not as patient or interested in my learning and on-going development. I also thought it was unfair because I had evidence to base my suggestions on. It was not a vague idea I had conceived but it was grounded in research. I felt powerless because as a junior and inexperienced member of the team I felt I had little influence over the overwhelming hierarchy. Morris (2004) states that student nurses possess little power because they are viewed as inexperienced. I wanted to make my mentor realise that the patient could be suffering (from diarrhoea and regurgitation) because of our negligence and not from inevitable causes. Why was Cognitive Learning Being Achieved? In this situation I was learning a number of things, mainly relating to communication, team work, assertiveness, accountability and responsibility. I learned that my priority is with the care of my patient and not with my popularity among colleagues, just as the NMC (2008) signifies when it states when facing professional dilemmas, your first consideration in all activities must be in the interests and safety of patients. When I met with my original mentor on her return back to work we discussed this incident of practice and she praised my efforts in extending my knowledge to improve patients care. I therefore achieved the competency, actively seeks to extend own knowledge. Do Any Barriers to Learning Exist? The barriers that existed to my learning were the apathy of the nurses and the limits of my own assertiveness. It was very hard on this ward to feel proud of the care that was being given. The ward was poorly staffed, the ward manager was unanimously unpopular, the ward relied heavily on agency staff that was not familiar with the ward and my temporary mentor wanted to leave nursing because of all of the above (and more). As a new and enthusiastic team member I found my self fighting against the low morale and low motivation of the current staff. Job satisfaction can impact on the care that nurses provide. Brown (1995) believes that when nurses enjoy good job satisfaction they provide a higher standard of care to their patients. Rohrlach (1998) and Govier (1999) cited by Kitson (2003) discovered that nurses who were happy with the care they were giving were more likely to stay within the clinical area which would in turn provide some stability and security within the workplace. Accor ding to this research, the inability to give quality care (due to the problems mentioned) was resulting in low morale. The dilemma I faced was as follows. I had already approached my mentor once regarding Johns problems and detected that there was little interest in what I had to offer and in the nurses willingness to correct any problems. If I addressed the issue again, I risked worsening the relationship between my mentor and myself. Morris (2004) identifies that student nurses often feel nervous about speaking out because they feel the need to conform or do not wish to be viewed in a negative way. Student nurses risk upsetting the status quo by speaking out. If I left the issue my patient may be suffering discomfort unnecessarily, but as a student I will never be held accountable in a way that registered nurses midwives or health visitors are (NMC 2008). Would this justify me leaving the issues and conforming to the apathy and bad practice of my mentor? Morris (2004) disagrees. She says that although students are not legally accountable for their actions and omissions, they are morally responsible for ensuring that patients are receiving good standards of care. The student nurse must be responsible. Semple and Cable (2003) affirm that responsibility is concerned with answering for what you do. Registered nurses, midwifes and health visitors are accountable which, Semple and Cable (2003) defines as being answerable for the consequences of what you do. 3.) Re-evaluating the Experience Drawing Conclusions Drawing conclusions is the most vital part of the process of reflection. It will shape future practice and quality of care. Conclusions that are drawn from reflection must agree with the Nursing and Midwifery Council code of professional conduct. It is with the NMC that all matters of conduct, practice and attitude are dictated to nurses. The NMC (2008) motto, protecting the public through professional standards can only be achieved if all those on the NMC register are willing to submit to the conditions and regulations that it upholds. Indeed Somerville and Keeling (2004) affirm that in order for nurses to meet the demands of the NMC, they must focus on their knowledge skills and behaviour which can be achieved through reflection. On reflection of the described incident, it was difficult to know what to do. My mentor was not up to date with the knowledge of this area of practice. I cannot, and do not expect her to know everything, however Glover (1999) points out the nurses should be reliant on others for information. The NMC (2008) states that nurses should work cooperatively within teams and respect the skills, expertise and contributions of colleagues, treating them fairly and without discrimination. Therefore I expected my temporary mentor to take more interest in what I had to offer. Indeed Morris (2004) argues that qualified nurses are obliged to listen to other staff regardless of their qualification status. Announcing that practice should be in accordance with the NMC is too simplistic an answer to such a diverse problem. It is correct to say this but how will this be achieved? The ward is in need of good clinical leadership, first of all from the sister in charge. Nadeem (2002) states that the call for good leadership in the NHS has reintroduced the matron figure and also the new role of nurse consultants. Specialist nurses do have a role in ensuring safe practice and quality care but this should be in addition to effective local leadership i.e. leadership from the ward sister. Leadership is perceived as being good if there is good team working and if managers have good relationships with staff (Lipley 2003) which is one area that needs consideration in this scenario. Meeting the staffs needs improves satisfaction, productivity and efficiency (Nadeem 2002) which in this instance principally means the provision of resources, i.e. human resources. Nurses who are happy with the care they give are more likely to stay within their clinical area (Rohrlach 1998 and Govier 1999 cited by Kitson 2003). This would provide some stability and security in the workplace. Clinical governance has also come to play a prominent role in ensuring quality care. The government has defined clinical governance as a framework through which NHS organisations are accountable for continuously improving the quality of their services and safeguarding standards of care, by creating an environment in which excellence in clinical care will flourish (Department of Health 1998). It had been noted that unacceptable variations in clinical practice where becoming common in the NHS (Department of Health 2010). While some patients were receiving excellent health care, e.g. in stroke care, other patients in the country were receiving sub-optimal stroke care due to differences in facilities, funding, education and staff. Each clinical area can improve the quality of care by (1) using modern matrons and nu rse consultants as clinical leaders, (2) by having adequate staff to care effectively and to lift morale among existing staff and (3) by implementing clinical governance which will result in the flourishing of good practices across wards, departments and NHS trusts through the sharing of expertise, research and ideas. The wards problems could also be addressed through annual reviews or by encouraging staff to keep an up-to-date portfolio (Somerville and Keeling 2004). This will allow nurses to identify strengths and opportunities for development. Critically analysing using reflection on this incident has been valuable in maintaining the quality of care as set out in the NMC code of professional conduct. Gallacher (2004) says that she questions different peoples practices in order to provide her patients with first class quality care. Clinical practice will not improve if it remains unquestioned. Hindsight gives the practitioner the opportunity to discriminate between good and bad practices. Safe, legal and quality care can only be given if it is in keeping with the NMC code of professional conduct. Reference list Arrowsmith, H.

Nursing Process Change Paper -- pre-operative management

The pre-operative stage is an important phase in patient’s surgery process. This is the time where the patients is experiencing a lot of anxiety issues and have questions regarding the impending procedure. To help ensure good patient outcomes, it is imperative to provide complete preoperative instructions and discharge instructions (Allison & George, 2014). It is the nurses’ duty to safe guard and protects the patient’s welfare during the surgical experience. Effective preoperative preparation is known to enhance postoperative pain management and recovery. Health professionals need to be cognizant of the contextual factors that influence patients’ preoperative experiences and give context appropriate care (Aziato & Adejumo, 2014). This essays attempts to address the elements of pre-operative management and issues that could potentially cause surgery delays or cancelation at the Veterans Affairs Southern Nevada Healthcare System (VASNHS) Surgical Spec ialty Outpatient department. Moreover, it also depicts the need for a new pre-operative management system. Assessment New consults for the Surgical Specialty Outpatient department comes from the primary care provider. During the initial visit the surgeon evaluates the patient and discusses the plan of care. If patient requires surgery, the surgeon orders pre-operative tests such as blood work, urine test, electrocardiogram (EKG) and chest X-rays. After completing the â€Å"buck slip,† a hand written operating room (OR) request form, the surgeon hands it to the primary care nurse of that particular Surgical Specialty clinic.

Simplex Method

A comprehensive look at the compensation methods and benefit program is necessary to reveal any holes in the system. The company will then explore the many options available to it when deciding on a compensation package suite to both the employee and the organization. An objective function is when you have one word that is the keyword. And that keyword Is either minimized or maximized. You can do this to a name, colon, or a linear equation. â€Å"Although a particular linear program must have one objective function, a model may contain more than one objective declaration. (Fourier, Gay, & Kernighan, 2003, pig. 34, Chapter 8). Constraints are a little different than objective functions. But they do have some similarities. The Similarities are that they both use a keyword the only thing is in constraints you do not have to have a beginning keyword like you do in and objective function. â€Å"The name off constraint, like the name of an objective, is not used anywhere else in an algeb raic model† (Fourier, Gay, Kernighan, 2003, pig. 134, Chapter 8). Both the objective function and constraints work well together you cannot use one without using the other. The simplex method was invented by Gorge B.Dating in 1947. The simplex method is the most superior tool used today in most applications of linear programming. Tangle's work has been honored many times. To name a few, The National Medal of Science In 1975, the Jon Von Neumann Theory Prize of the Operations Research Society of America, and the Institute of Management Science, In 1974. He believed that the greatest theories must pass the final test of being able to solve the problem that originated it (Dating, 1994). He worked with the U. S. Air Force where he became an expert on planning methods solved with your every day desk calculator.At the time this was called â€Å"programming†, a term used by the military referring to plans or schedules for the training, deployment of men and logistical supply f or them. Today, many industries use the simplex method to maximize or minimize profits and costs throughout the company. Management within these companies uses the simplex method to disperse scarce resources amongst the company. Industries use the simplex method to find the best way to allocate these resources such as labor, trials, machines and capital (Using the Simplex Method – Oregon State University Extension Service, 1998).Simplex Method within Winter Technologies use of the simplex method will be demonstrated to solve a common resource allocation situation faced by many companies. Winter Technologies has been has the following resources available to work on the project. Technical resource one costs $1 5/hour and is available for a maximum of 30 hours. Technical resource 2 costs $20/hour and is available a maximum of 40 hours. Technical resource 2 costs $25/hour and is available a maximum of 50 hours. The company would also like to have technical resource to work for le ss than one third of the hours on the project.If this restriction had not been placed on Tech 2, the total cost of the project could have been reduced as Tech 2 could have taken on more hours under its constraint. Conclusion The simplex method is used to solve problems in linear programming. This was a big undertaking for Winter Technologies and should not be taken lightly. Every linear program can be converted into standard form where the constraints are equalities and the objective is maximized and nonnegative are the variables. All elements described were carefully considered before the project is undertaken.A poorly lactated linear program can mean disaster for the company and can take years to erase. With this consideration in mind Team A use the simplex method that allows them to improve the solution at each step. The simplex method will start from a random vertex value of the objective function and repeatedly find another vertex value that improves the one you have before. On ce the team standardized the model, they begin to implement the simplex method. To begin the team uses the simplex incoming variables, choosing the variable that slips out, updating the board, and return result.

An Analysis of Orwell’s “Shooting an Elephant” Essay

In â€Å"Shooting an Elephant,† George Orwell finds himself in a difficult situation involving an elephant. The fate of the elephant lies in his hands. Only he can make the final decision. In the end, due to Orwell’s decision, the elephant lay dying in a pool of blood. Orwell wins the sympathy of readers by expressing the pressure he feels as an Anglo-Indian in Burma, struggling with his morals, and showing a sense of compassion for the dying animal. Readers sympathize with Orwell because they can relate to his emotions in the moments before the shooting. Being the white â€Å"leader,† he should have been able to make an independent decision, but was influenced by the â€Å"natives† (Orwell 101). Orwell describes his feelings about being pressured to shoot the elephant: â€Å"Here I was the white man with his gun, standing in front of the unarmed crowd – seemingly the leading actor of the piece; but in reality I was only an absurd puppet pushed to and fro by the will of those yellow faces behind (101). Everyone has been in a situation in which he or she has been expected to be a leader. For different reasons people are looked to as leaders, sometimes because of their race, ethnicity, or heritage. In this case, Orwell was pictured as a leader because he was British and he worked for the British Empire. Readers are able to relate to the fact that he does not want to be humiliated in front of the Burmese. He declares, â€Å"Every white man’s life in the East, was one long struggle not to be laughed at† (101). Orwell compares the elephant to the huge British Empire, and just as the elephant has lost control, he feels that when the white man turns tyrant it is his own freedom that he destroys (100). Secretly he hates the British Empire and is on the side of the Burmese (97). The elephant is equivalent to the British Empire ravaging through Burma and disrupting the little bit of peace that they have. So in that instant he felt that he had to kill the elephant. Another aspect that wins reader’s sympathy is Orwell’s struggle with what he  thought was right and what the Burmese wanted him to do. The readers have a sense that he did not have ill-intent to kill the elephant. When Orwell says, † As soon as I saw the Elephant I knew with certainty that I ought not shoot him† (99). The readers know that cruelty or hatred for the beast was not his motive. Orwell repeats the he does not want to kill it and the readers sympathize with him. Almost everyone has been in a situation were he or she could not base a decision on personal beliefs and knows that going against those beliefs is very difficult. Orwell explains, â€Å"For it is the condition of his rule that he shall spend hid life in trying to impress the ‘natives’ and so in every crisis he has got to do what the ‘natives’ expect of him† (100). Readers respect Orwell for his sense of duty. He realizes the his decision must be based on the best interest of the Burmese. Also, Orwell showed great feelings of compassion for the dying animal. He was killing the animal because he had to. He did not feel strong and powerful, as a hunter would; he felt weak and helpless. Orwell so vividly describes the elephant’s death, almost as it were giving him pain to watch. The elephant lay, â€Å"dying, very slowly and in great agony. . .† (Orwell 102). While the elephant lay dying Orwell can feel nothing but helplessness. He describes the experience as â€Å"dreadful to see the great beast lying there, powerless to move and yet powerless to die, and not even to bee able to finish him† (102). He felt helpless, with no bullets left in his gun; he was unable to put the elephant out of his misery. The compassion that he felt was obvious, he waited so long for the animal to die but, â€Å"could not stand it anymore and went away† (Orwell 102). The detailed description that Orwell gives of the death leaves the impression that he actually had feelings for the animal. If it were a routine killing he would have not even considered how the elephant felt. Orwell was very detailed about his feelings about the killing through out the essay. Most readers have respect and sympathy for him because of his emotional turmoil before the shooting, his struggle with his own feelings about killing, and his feelings of sadness for the elephant.

Ye Tao BISC220-13155 The Effect of Temperature on the Digestion of Starch by Activity of Enzyme ? -Amylase: Observation of Rate of Starch Disappearance through Iodine Test Introduction An enzyme is a type of protein that, through its own structure including hydrogen bonds, acts like a biological catalyst and is able to accelerate the biochemical reaction rate by lowering the activation energy of the whole process, without which cells could hardly practice any physiological functions within human bodies (Sizer, 1943).Found in the saliva and pancreatic secretions of animals including human beings as well as the plant seeds, bacteria and fungi (Siddiqui et al. , 2010), the enzyme ? -amylase that was studied during the experiment has significant impact on the hydrolysis of starch. By breaking the alpha, 1-4 glycosidic linkages in the carbohydrates, amylase hydrolyzes the starch, a polysaccharides that is stored in plants and cannot be directly digested by animal cells, into maltose, a di saccharide that later generate two units of glucose to undergo metabolisms and provides necessary energy (Slaughter et al. , 2001). The enzymatic activity of ? amylase is facilitated by calcium and chloride ions during the hydrolysis (Marini, 2006 and Siddiqui et al. , 2010). The complete digestion of starch and formation of maltose and glucose can be examined through the iodine test when I2KI reagent is added into the solution and remains brown instead of turning into dark blue, marking that all the molecules of starch have been fully hydrolyzed (Hanes, 1932). While amylase effectively activates the hydrolysis of starch, the efficiency of the catalytic process is influenced by several factors including temperature, pH level and the concentration of the substrates etc.In this experiment, as the ? -amylase is a type of protein, the efficiency of enzyme is highly related to its hydrogen bonds which are affected by the temperature. Though the enzyme is collected from the porcine pancre as, due to its structural similarities to amylase in human bodies, the behaviors of two amylases should resemble each other. Given that under extreme temperature enzymes will be denatured and unable to function and the constant temperature of pigs is around 39 °C, the hypothesis of this experiment is that at 37 °C amylase will catalyze the hydrolysis with the highest speed, followed by amylase at 22 °C.Amylase at 0 °C will react extremely slowly due to the crystallization of hydrogen bonds and at100 °C, amylase will lose its function since it will be denatured. Materials and Methods Four test tubes were marked from A1 to A4. Then, 2mL of 1% starch solution from Carolina Biological Supply Company, 4mL of deionized water and 1mL of 6. 8 hydrion buffer from VWR International/ Micro Essential Laboratories were added into each tube. Another four test tubes were also labeled from B1 to B4 and added 1mL of 1% ? -amylase from porcine pancreas from Sigma Aldrich. Eight tubes were p aired according to the same number (A1and B1 etc. and assigned to environments at different temperature: Tube A1 and B1 were placed into a water bath at 100 °C; Tube A2 and B2 were placed into a water bath at 37 °C; Tube A3 and B3were placed on the tube rack (at about 22 °C); Tube A4 and B4 were placed into an ice bath at 0 °C. All test tubes were kept at different temperatures for 10 minutes. Meanwhile, a control group of starch solution was prepared without amylase. (Bio Lab Manual, 2013) At the same time, a test plate was added 2 drops of I2KI reagent (1% Iodine and 2% KI) from Carolina Biological Supply Company per well.After 10 minutes, when test tubes were still in the original environments, solutions in Tube A1 with B1 were mixed and a timer was started. At each 30-second-inteval, a drop of the mixture was released into the well on the test plate until the solution in the plate did not change into dark blue and remained brown, indicating the end of the reaction by sho wing no presence of starch and presence of maltose and glucose. The experiment was repeated on the tubes at other temperatures. Slow reactions were observed and recorded up to 420 seconds due to time limit.Data were pooled from each bench and average and standard deviation were calculated. The data of the control group were also obtained. Results Figure 1 The test plate of iodine test under different temperature. Dark blue wells indicated the presence of starch while the brown ones indicate the completion of starch hydrolysis. (Upper half: 37 °C; Bottom Half: 0 °C) The rate of reaction was fastest at 37 °C (n=4, mean=212. 5s, SD=66. 1s) while the rate of reaction at 22 °C was only slightly less than it (n=4, mean=217. 5s, SD=61. 8s).Though the previous two groups underwent starch hydrolysis relatively fast, the tubes at 100 °C and 0 °C reacted so slowly that it took more than 420 seconds for their completions (time was only recorded before 420s). There was no hydrolysis in the control group. The time of the reaction completions as the function of different temperatures was shown in the table and graph below. The Effects of Temperature| Temperature (? )| Time of Starch Disappearance(s)| | Bench 1| Bench 2| Bench 3| Bench 4| Mean| SD| Control| >420| >420| >420| >420| 420| 0| 0| >420| >420| >420| >420| 420| 0| 2| 210| 210| 300| 150 | 217. 5| 61. 84658| 37| 270| 180| 265| 135 | 212. 5| 66. 14378| 100| >420| >420| >420| >420| 420| 0| Table 1. Time of Starch Disappearance with Porcine Pancreatic ? -Amylase at Different Temperatures (Time was recorded up to 420s). Graph 1. Time of 1% Starch Disappearance with Porcine Pancreatic ? -Amylase as the Function of Different Temperature Discussion and Conclusion As the data obtained from the experiment, all parts of the original hypothesis were confirmed by the result. Temperature plays an important role during the activation of ? amylase that only during certain temperature range can the enzyme function properly to catalyze biochemical reactions. On one hand, at 37 °C the amylase showed the greatest efficiency in catalyze the hydrolysis of starch. At the same time, the amylase also showed considerable catalytic efficiency at 22 °C. But on the other hand, when temperature dropped or rose to extreme value such as 0 °C or 100 °C, the function of amylase was inhibited and such biochemical transformation of substances could hardly process. This result obtained is consistent with the reality that during normal body temperature, regardless of pig or human beings, mylase is able to catalyze the hydrolysis of starch with the highest speed. Therefore, we may conclude that even taken out from where it was found, the amylase still maintain its original biochemical properties. The experiment did not show the biochemical mechanism of the modification from temperature to amylase activity. However, according to the scientific research done by other scientists, a temperature that ranges from 20-50à ‚ °C could make structures including weak interactions, hydrogen bonds and disulfide bridge exist within and stabilize the enzyme molecules to maximize their activities.At the water freezing point (0 °C), the hydrogen bonds are crystallized and become more constrained and less flexible while at high temperature like 100 °C, the bonds consume certain energy to become unstable and fragile, neither of which contribute to the proper functions of amylase (D’Amico et al. , 2003). While the result of the experiment perfectly matched what was expected, however, such conclusion could only be made at qualitative phase and it is obvious that weakness of this experiment existed and prevented the further understanding of amylase at quantitative level.Several modifications to the current experimental designs could be made to enhance its accuracy. Firstly, the sample size needs to be expanded. With only four groups, the data was so limited. As a result, the data had great standard devia tions of more than 60 seconds. Simultaneously, the random errors were at high possibility to take place. Therefore, with the increase of sample size, the data can be more accurate and stabilized and potential random errors could be discarded to ensure the coherence of the data.Furthermore, even though neither the test tube at 0 °C and 100 °C enabled the completions of starch hydrolysis, the reasons of the two groups are not the same. Therefore, in order to detect the reason of the loss of catalytic ability, follow-up experiments need to be practiced. A possible design might be to change the test tubes from 0 °C or 100 °C into 37 °C for another 10 minutes then redo the iodine test to see this time whether the amylase can function well or not.This manipulation will convince the hypothesis about the reason behind the superficial phenomena that was shown in the original experiments and present the difference between denaturing of protein and crystallization of hydrogen bonds. It is important for people to thoroughly understand the amylase activity and all the factors that are potentially capable of influencing such activity through which people can understand how human bodies work as well as the physiology of other organisms. At the same time, the research in amylase activity could potentially bring economical benefits to industrialized starch products manufacturing.And finally, the amylase activity has shown its significance in medical clinical trial that diseases including hyperamylasemia  or hyperamylasuria are proven to be related to the amylase in the human serum and urines (Salt 2nd, 1976).

Bio Lab Report Biology lab report Estimating glucose concentration in solution Done by : Hasan Al-jowder 11E KC Introduction: The purple pink solution of potassium permanganate (MnO4 -) is reduced by glucose to a colourless solution of manganese ions (Mn2+). MnO4- + 8H+ + 5e- Mn2+ + 4H2O The time taken for the loss of colour from a standardised solution of permanganate is directly related to the concentration of glucose present in solution. Research question:How does the different concentration of glucose solution which have the same volume affects the time taken for the pink color of the potassium permanganate to turn into colorless? Hypothesis: The higher the concentration of glucose, the shorter time taken for the reduction of potassium permanganate, hence resulting in shorter time taken for the pink color of potassium permanganate to decolorize. This is because the concentration of glucose molecules in glucose solution is high thus more electron are donated to the permanganate within a constant period.Variables: †¢Independent: The concentration of the glucose solution †¢Dependent: The time taken for the pink color of the potassium permanganate to turn into colorless †¢Controlled: Volume/Units Materials list : †¢Eye protection †¢A timer †¢a glass rod †¢a boiling tube and a rack †¢3 beakers †¢3 syringes †¢6 labels †¢glucose solutions (2%,4%,6%,8%,10%,12%) †¢3 solution of unknown glucose concentration (A,B,C) †¢sulphuric acid †¢potassium permanganate Procedure: 1. label your three beakers sulphuric acid PP- for potassium permanganate G- for glucose 2. abel your syringes in the same way. 3. add about 25 cm3 of sulphuric acid and potassium permanganate to the beakers – this will be your stock to use throughout the experiment. note which glucose solution you are testing first. 4. use the correct syringe to place 10 cm3 of the first glucose solution into the boiling tube. 5. add 5 cm3 of sulphuric acid. 6. add 2 cm3 of potassium permanganate and start the clock. 7. stir with a stirring rod and stop the clock as soon as the pink color disappears. 8. record the time and the glucose solution used. . rinse the syringe you used for the glucose solution. 10. repeat using the other glucose solution. 11. repeat for a solution of unknown concentration (A B or C) 12. record your own results and if possible class average results in a table.

The Life Story of Henry G. Appenzeller

Not much has been written about Korea, or of its people, their deeds and heroism.   However, one work displayed Korean character though a biography of an ordinary missionary who turned out to be a significant personality in the history of Korea and its transformation.The book, â€Å"A Modern Pioneer in Korea:   The Life Story of Henry G.   Appenzeller by William Griffis, is yet another biography that showcases heroism.   The book is about sacrifice and giving up something for other people.   In his story, Henry showed that it does not take much to be able to help other people and to become a hero for ordinary people.   For example, it does not take to be rich, or to be a prominent person in order to affect other people’s lives.Griffis started his discussion by giving a background about Appenzeller and Korea.   In this way, the readers can recall and picture what Korea was and how Appenzeller affected the lives of the people and how he helped them change for the better.Henry Appenzeller was a missionary for the Methodist church in Korea.   As a missionary, he is able to save the lives of young people in Korea by giving them a new chance for education and serving as an inspiration for them.There are a number of instances by which Griffis was able to show that Appenzeller is a noble man.   First, he was able to preach and educate the people of Korea in six different languages.   He preached about righteousness without being hindered by the various barriers like language and culture.The book is a very inspiring record of Korean heroism, which is apart from the popular reputation of Korea being isolated from the world of heroism and humanity.     Ã‚  The author, Griffis, did an effective narration of what seemed to be the greatest achievements and contributions of Appenzeller in the modern Korea.What is good about his book is that Griffis was able to substantiate and provide concrete evidence for his claims pertaining to Appenzellerâ €™s heroism.   This is very important because as a biography, it should be based upon real experiences and real events in the subject’s life.As a missionary, Appenzeller was able to affect change for the Korean people by incorporating prayers in their lives.   It is never denied that Korea was one of the most mythical and mysterious nations in the Asian region, very much in touched with its culture and tradition.   This, to my mind is one of the primary reasons why Korea’s growth was stagnated.   Fortunately, the modern Korea has learned to be social and unashamed of its self and unafraid to consider changes.Figuratively speaking, the work is full of picturesque words used effectively to show greatness.   The author’s approach gave the biography a poetic appeal so that unlike any other biography, the work seems to have been creatively written as a real literary masterpiece.It can also be observed that as much as the book is also about Appenzellerâ €™s missionary works, much have been mentioned about the Gods, and religion.   Although at one point, it may seem unnecessary, the approach nevertheless has been effective in relating the role of religion in Korea’s transformation and in explaining the behavior of the poe0ple, particularly of Henry Appenzeller.In sum, the book is another archaic inspiration and recognition of Korean heroism that until today contributes to the continuous improvement of Korea and its people.Work CitedGriffis, William.
