To investigate whether the amount of paper cup cake holders affects the time taken to fall a certain distance Essay Example

To investigate whether the amount of paper cup cake holders affects the time taken to fall a certain distance Essay When I do this experiment to find the terminal velocity I will drop 1 cake cup from a certain height ( which will be kept constant throughout the experiment.) When the cake cup is dropped a stop watch will start, then will be stopped when the cake cup hits the ground. I will then repeat this experiment using 2 cake cups, then three and so on. Altogether I will take 10 different weight readings, each weight reading done 3 times, so I can have a wide range of accurate results a total of 30 giving me a spread to plot on a graph. When doing the experiment, to make sure it is fair I will do the following things: Make sure the cake cup is dropped from the same height each time, if it wasnt then the results would be inaccurate.I will make sure the same person times the cake cup falling, this is because different people have different reactions. We will keep the same sized cake cups, as a different surface areas would lead to wrong results ( I will presume that the cake cups I use will weigh the same). When doing the experiment I will make sure there is nothing that could affect my results E.G wind or obstacles in the way, this would effect the falling time of the cake cup, therefore giving inaccurate results. The variable I will be changing will be the amount of cup cake holders, however there are many more variables I could change in order to make a comparison with other sets of results.During the experiment it is essential to ensure the cup cakes reach terminal velocity in order to find this I took some preliminary results in the form of a pre-test.Pre-TestThis was completed before the main experiment by taking 10 cup cake holders ( the maximum amount of cups I will use in the experiment), and timing how long they took to reach the ground from different heights. (In these preliminary results I changed the height so I could get several readings and plot them onto a distance time graph. From this graph I could then see when the cake cups had reached their terminal vel ocity.Height1.0 metre2.03.04.05.02.563.183.183.293.30It was clear from the results of the pre-test that the cup cakes had reached terminal velocity between 4 metres and 5 metres because the speed from this height would not increase anymore so we decided for the main experiment to use a constant height of 4.6 metres.Prediction:I predict that the terminal velocity will increase as I increase the weight of paper cups therefore the times will decrease when more paper cups are dropped and terminal velocity is reached.Justification for prediction:I think that the weight affects terminal velocity because I know that heavier objects fall faster than lighter ones. (E.G a brick falls faster than a feather). Bigger objects push air molecules out of the way faster than small objects when they fall to the ground. As air resistance affects the terminal velocity, terminal velocity occurs when gravity and air resistance are balanced causing the increase in acceleration to stop. At the instant of re lease there is no friction because the object is not moving. The weight of the object makes it accelerate downwards, because gravity is acting on it, the heavier the object the faster it will accelerate, because gravity is a constant force, it always stays the same; the velocity and the air resistance have to increase to balance it. So unless the weight of the paper case changes there is always the same force of gravity acting on it. So I expect that there will be a straight line of best fit on the graph. This is the reasoning behind my prediction.Equipment:I will use the following equipment throughout the experiment -* Metre Rulers (x5) (maximum height 4.6)* Paper Cups (x10)* Stop ClockDiagrams:Fair test:To ensure my results are accurate and fair I will:* Drop all of the cup cakes from the same height of 4.6 metres at the same angle.* Dropping each one 3 times and then finding the average.* Use the same size and type of cake case each time.* Make sure the same conditions are kept c onstant throughout.Variables:If I needed to complete the experiment again and compare my results with another then I could change one variable. These however must be changed one at a time or the tests wouldnt be fair and the results would be inaccurate because the results would be vague due to the uncertainty of how they differ from before due to having more than one variable.The range of variables for this experiment are :Number of cup cake holders- I chose this one because it is probably the most simple and easy to set up yet has the best outcomes and most accurate results as patterns and graphs can be made with ease.Conditions- This change would mean testing just one cup cake holder in various conditions and making valid observations and reasoning to why and which conditions affect the rate of terminal velocity.The way it which it is dropped- If this variable was used then the cup cake holder could be dropped sideways therefore decreasing the surface area meaning the air resistan ce will be less and as a consequence the terminal velocity changingResults:Table 1-Results 30 drops 10 different weights.Figure 1Amount/Attempt1st2nd3rd13.313.023.2422.392.052.3831.951.951.9941.661.71.7351.591.491.5361.381.431.4971.381.431.3881.341.381.3391.271.511.21101.201.261.17The results above show all 3 attempts in order to gain an accurate average to be able to plot a graph to simplify the results collectively.The graph shows a steady decrease in the time take for the cups to drop as more weight is added. If we were to increase the amount further then the graph would continue to form a steady slight curve until it made an end with a drop closer to 0.5 m/s. (marked with a star) There were however some anomalous results during the experiment and these have been highlighted in the results table(figure 1.)with an underline. Also another observation was that there were also some results that stood out according to there row, this means that they do not follow a pattern and seem ou t of place where they stand. These can be seen marked with a star. These results can be put down to either human error or a slight change in a variable such as the conditions, to correct this another retest should have been done to clarify any anomalous results.Average:Amount of cup cakesAverage (2.dp)Average (1.dp)13.193.222.272.331.962.041.701.751.541.561.431.471.401.481.351.491.331.3101.211.2The table rounds up all the data from the previous graph and gives an average to allow me to plot it onto a graph with a reading closest to either1dp or 2dp.The equation:Speed = Distance ? TimeI used this to find the speed within my terminal velocity experiment, if you substitute the worded equation with the data all of the speeds can be found in m/s. I have used the average reading closest to 2.dp/Table:Amount of cup cakesSpeed m/s11.4422.0332.3542.7152.9963.2273.2983.4193.46103.80Analysis:The results gained from the experiment show that my prediction was correct, as the amount of paper cups increase the terminal velocity is faster, the shorter time it takes for it to hit the ground. So then the more paper cake cases that were dropped the faster its terminal velocity. At the instant of release there is no friction because the object is not moving. The weight of the object makes it accelerate downwards, because gravity is acting on it, the heavier the object the faster it will accelerate.The results show that the terminal velocity increases steadily each time. 3.15m/s is the average increase in the terminal velocity each time another paper cake case is added. This shows that adding extra weight increases the terminal velocity. This is because terminal velocity is when the air resistance becomes equal to the gravitational force acting on the object and so the acceleration stops. The heavier the object the shorter time it takes for it to reach its terminal velocity.Evaluation:I think the experiment worked quite well, a lot of reliable results were obtained which could be analysed easily and this meant we were able to complete the aim. Most of the results are quite reliable; we did 3 experiments at each weight (3 drops with a total of 10 cup cakes) and took an average, which meant they were quite reliable. But because of human error they may not have been as reliable as they could have been, these human errors are responsible for the anomalous results on the graph. We could have improved the experiment by using electronic sensors, to drop the paper cases, this would have eliminated human error.The main error I think was delayed reaction times. When the cup/s were dropped, it would have taken the timer some time to start the stopwatch after it had passed the beginning of the timing point. Also if different people were timing they would obviously have different reaction times therefore affecting the results. If I did this experiment again I would have the same person each timing, also I have the person timing standing at a point where they could clearl y see when the cake cup passed. Also the stopwatch could only be measured to an accuracy of a 10th of a second.Another problem that occurred was that when the cake cup fall though the air there was some movement. The cup tended to sway from side to side which meant there would not be a constant area,(meaning the surface are constantly changing) which would obviously effect our results as there would be extra movement from side to side. If I were to do the experiment again, it would be hard to eliminate this error. The only way this could be slightly improved would be to ensure the best conditions possible to do the experiment in (a wind and draft free place.)After I had plotted my graph I found that there were one or two anomalous results, and this could have been because of any of the errors above. I re-tested this result and my new result fitted in better than the original result. I can conclude that the terminal velocity does depend on the weight, and this can be clearly seen whe n looking at my graph which follows a steady decline in the time take for the cups to drop. If I had decided to use the way it was dropped as variable then my results would have differed slightly, this is because the surface area would change if for example they were dropped at an angle then the times maybe would have had a slower decrease. The graph would have looked more or less the same but the time taken for the cups to fall would be longer.

«Things Fall Apart» by Albert Chinụalụmọgụ Achebe

 «Things Fall Apart » by Albert Chiná » ¥alá » ¥má » gá » ¥ Achebe Achebe’s Things Fall Apart is an enthralling must-read chef-d’oeuvre starring Okonkwo, the protagonist who, despite his hatred towards his father, ends up taking after him. From the first line, the author begins by presenting Okonkwo as a well-known man even beyond the nine neighboring villages.Advertising We will write a custom essay sample on  «Things Fall Apart » by Albert Chiná » ¥alá » ¥má » gá » ¥ Achebe specifically for you for only $16.05 $11/page Learn More The tall, muscular, and fearful character that had unkempt eyebrows and broad nose resented his father for being lazy and irresponsible. Okonkwo is hard working and successful because he tries hard not to be like his father. However, as the paper unveils, Okonkwo’s life is full of contentious situations ranging from failing his people, being a dependant rather than a provider, and being hopeless amongst others, that perhaps make him resemble his father whom he never wanted to emulate. Okonkwo resented his father’s failure even when he was merely a boy. Even at the helm of his success, he still remembered how he suffered when his playmate said his father was an agbala. From that moment, he learnt that Agbala, not only meant a woman, but also a name for any man with no title, like his father (Achebe 9). In some sense, these titles did not mean anything to foreigners. Therefore, by the time Okonkwo came to die, he was more or less like his father. He had titles that could not help him, as there was a new system of law. He had titles, which were useless just like those of his father. When Okonkwo and other people of Umuofia decide to take a substantive measure of burning the church, the District commissioner invites them to his office for what he calls palavers. The six leaders agree to attend because meetings like that were normal. The court messenger even mocks them because of their titles. †Who is chief among you?’†¦Thes e anklets are worn even by any pauper now; does it even cost ten cowries?† (Achebe 152). At this point, Okonkwo who was extremely scared of failure, had failed to defend his honor. He slept in the cells and he could do nothing about it. He feared feeling weak as his father. However, at this time, he was literally weak. The new system did not recognize titles and many titled men were through to prisons despite their social statuses. Unlike Unoka, Okonkwo wanted to feel powerful in the community. He hence worked tremendously hard to exceed the worthless status of his father. In this endeavor, he hurt people close to him. They eventually resented him just as he had resented his father. It is hence sensible to say that, in the end, Okonkwo failed the people who depended on him, who trusted him and those who wanted to follow his example. The saddest episode was the Killing of Ikemefuna. The council of elders entrusted this ill-feted boy to Okonkwo. He was one of the two people Umuo fia got from Mbaino clan in exchange for their daughter who had died. Mbaino compensated Umuofia giving them a virgin girl and a boy, Ikemefuna (Achebe 8).Advertising Looking for essay on literature languages? Let's see if we can help you!

He ended up living there for three years (Achebe 40). He became a mentor to Nwoye, Okonkwo’s eldest son. Ikemefuna, in fact, became like family and called Okonkwo father. Nwoye became more responsible with Ikemefuna around. Nwoye felt like a grown-up (Achebe 40). Something that excited his father clandestinely and he knew it was because of Ikemefuna. The Oracle of fate finally decided that the boy worth sacrificing to Agbala. Okonkwo and other villagers under the pretext of returning him back home took the boy to the forest to kill him. â€Å"While in the forest , a man cleared his throat, this scared Ikemefuna who turned back, the man growled to let him keep moving† (Achebe 47). The boy trembled. His body began to shake. The ma drew his machete, as he raised it Okonkwo looked away but he heard the blow. The pot the boy was carrying fell and broke. The Boy screamed to Okonkwo, â€Å"My father, they have killed me! While running towards him. Because of fear of being thought weak, Okonkwo drew his machete and slew the boy down† (Achebe 47). This was despite his peers warning him of having a hand in the boy’s death. At this moment, Okonkwo was more like his father because the boy depended on him for protection and love. However, he could not provide for him. He was so concerned about his reputation. He overlooked the sanctity of the life of an innocent boy who, in fact, called him ‘father’. Unoka failed to provide food for his family, which starved, he never paid his debtors and he was a failure for failing to be responsible for his family, his children. Okonkwo did not protect Ikemefuna, under his custody, a boy who looked up to him as a father figure, a boy who wanted emulate him. Nwoye is scared of him. He, in fact, sneaks out of the hut as soon as Okonkwo dozes off. Okonkwo was strong, hardworking, determined and ambitious, Contrary to his father who was hopeless, lazy and desperate. Okonkwo was a brave worrier while his father Unoka feared bloodshed and a coward who was only happy when he played his flute. Whenever he would get a little money, he would call his neighbors to celebrate and make merry, drinking palm wine (Achebe 4). Although, he was a man who worked as if possessed, â€Å"Okonkwo worked from cock crow until dusk when chicken went to roost† (Achebe 9). With these contrasts, Okonkwo ended up like his father hopeless. Okonkwo obeyed the Umuofia norms at the expense of his family. Just like his father who only thought about his happiness, playing the flute and celeb rating with palm wine whenever he earned little money. Okonkwo on his part was obsessed about obtaining tittles and growing his social status. In this course, he made silly sacrifices like slaying a boy who called him father.Advertising We will write a custom essay sample on  «Things Fall Apart » by Albert Chiná » ¥alá » ¥má » gá » ¥ Achebe specifically for you for only $16.05 $11/page Learn More Even his friend Obierika criticizes him. â€Å"If the oracle pronounces death sentence to my son, I would not be the one to kill him† (Achebe 52). That statement disturbed Okonkwo who defended himself that the earth would not punish him for obeying the oracle. However, that was brutal, barbaric and supremely primitive. During Ezeudu’s funeral, something unexpected happened. Okonkwo accidently blew-up his gun whose bullet inadvertently killed a sixteen-year-old boy, Ezeudu’s son. He quickly flew away. However, as the community laws dict ated, he had to atone for his sins by shedding the blood of a clansman. The villagers are aggrieved. They set fire on his houses, destroying his red walls, killing the animals, and demolishing his barn. The earth goddess wanted this justice upon Okonkwo as it were. The villagers were merely messengers. They did not hate Okonkwo. Even his greatest friend, Obierika was among the destroyers. Their duty was simply to cleanse the land, already contaminated by Okonkwo: killing a fallow clansman (Achebe 125). He was to live in exile for seven years. At this moment, Okonkwo has nothing. The whole fortune he had accumulated and worked hard for is nowhere following the destruction. He was as poor as his father was. The man who thought on issues, Obierika was thinking more that ever (Achebe 125), but he did not find answers. Obierika only remembers that, sometimes in life, a man needs to reevaluate his relationship with the society, and God (Achebe 125). This introspection was a sign that the society in which Okonkwo lived was ready to make changes. It was as if a curse was following Okonkwo. His father once went to an agbala to consult why his farming was not delightful. The priestess of the Agbala answered Unoka that he had nobody to blame but himself – for his laziness. In the same fashion, Okonkwo could only blame himself. After his exile, many things in the clan had changed. There were no more rituals, no more titles, and no more tribal land traditions. The Ugwugwu had been unmasked. The oracle was no more but a modern court of law for justice. He just realized he lost all things he grew up knowing that they defined a man. He could not go up against the system. He was weak and a terrible failure, as he could not save his clan. He ended up emulating his father. Achebe, Chinua.

Documenting the Media Revolution Essay Example | Topics and Well Written Essays - 1500 words

Documenting the Media Revolution - Essay Example Broadband Policy and Competitiveness†). One of the leading US associations, the Entertainment Software Association (ESA), stated that 49% of US households are delicately assuming the use of console through playing various computer games and it is not only affecting the teenagers but also the other varied age groups. Contextually, it also needs to be highlighted that the Internet is not only influencing the use of television simultaneously – it is becoming a great challenge for other mass communication media, i.e., newspaper, journal and books, to cope with the ever-increasing reach of the Internet (â€Å"Who is Playing†). Thesis Statement The paper intends to shed light on various factors regarding how the continuous increase in the use of computer as well as the Internet has vastly affected the habits of watching television. This is not only a concerning issue for the US but also has posed a great challenge to the other communication media throughout the world, e specially in developed and developing countries. Through the enormous effort of the World Wide Web (WWW) and with the emergence of a number of technological marvels created by a few software developers, it has resulted in significant changes in terms of the process of traditional TV viewership by providing various interesting ways of spending leisure time. Question 1 With regard to the first question in terms of the decreasing amount of viewership of TV by the teenagers and other age groups and enormous development of the Internet usage, various scholars and researchers have worked dedicatedly to find out the actual reason behind it. In relation to this crucial aspect, The New York Daily News (NYDN) provided a statistics of Nielsen’s research report on 19th September, 2012, showing that Americans spend around five hours a day watching TV. However, the report also has shown a significant concerning factor that the teenagers in between the age group of 12-17 are not interested in traditional TV watching. As a result, they are only spending around 3 hours for entertainment purposes among which most of the time they are watching videos via smartphones (â€Å"People Watch More Television†). The enormous indulgence in computer and the Internet has not only touched the teenagers but also has shown a significant spread amid various age groups till sixty years. This is because as per the obtained figures, it has come into light that only people belonging to the age group more than sixty spend approximately eight hours a day watching television. On the other hand, as per the report publication of The Telegraph of the United Kingdom, it is quite apparent that the Americans are in the number one position in terms of Internet surfing in the worldwide context (â€Å"Americans Spend Most Time on the Internet†). Besides Internet surfing in terms of video game playing, the Entertainment Software Association (ESA) provided a report showing that the average age group is 30 in

Can Concept of Enlightened Shareholder Value Succeed in Bridging the Essay

Can Concept of Enlightened Shareholder Value Succeed in Bridging the Gap between the Shareholder and Stakeholders Value Theories - Essay Example Does the concept of Enlightened Shareholder Value succeed in bridging the gap between the Shareholder and Stakeholders Value theories? Critically discuss the advantages, disadvantages and future perspectives of this new approach. 1. Introduction In the Enlightened Shareholder Value approach, much focus is given to â€Å"corporate stakeholders, including the environment, employees, and local communities† which are considered important in establishing long-term shareholder benefits1. Much debate has been seen throughout the years on what the goals of corporations should be. In order to seek an answer to this query, the shareholder value principle and the stakeholder theory has been considered. The shareholder value principle requires for a corporation to be managed in ways which support the shareholders over and above other parties having claims on the company. This principle has been seen in the US, the UK, Canada, and Australia. The stakeholder theory on the other hand declare s that the goal of the corporation must be to support all individuals who have been identified as stakeholders2. Under this set-up, the organization therefore seeks to manage the corporation for its shareholders, as well as all stakeholders who can be impacted by the organization. This theory is seen in Germany and in some European countries. In general, the shareholder value principle is being applied in most UK corporations. ... The current application of the shareholder theory is based on the Chicago School of Economics which highlighted the fact that the primary purpose of corporations is to maximize the wealth of shareholders; this theory also argues and that resolving social issues are state functions, not corporate functions4. Sharing wealth through philanthropy is therefore considered a useless enterprise for the corporation; in some instances, it may even be considered immoral because it is as good as stealing from the shareholders. The importance of the shareholder has been based on the principle of corporate law supported by the contractarian school in the US5. The contractarians declare that contractual relations among individuals within a company must be considered sacred6. These contractarians therefore uphold the right of the shareholders as the main basis for any corporation. This preference is based on the idea that for as long as the corporation is solvent, the company must be run in favour o f residual claimants7. These claimants have an interest in the company’s profits and therefore, their stake in the outcome of the company is also high. If the company suffers a downturn however, these shareholders also suffer to a significant extent. It is therefore important for shareholders to have a right to control the corporation over and above the interests of stakeholders8. 2.2 Criticism The shareholder theory is however very much focused on earning profits for its shareholders, with little to no concern at all attributed to how, who, or what is affected negatively by the corporation in gaining said profits. This theory also does not consider the environmental, social, cultural, and even political impact of their profiteering

Issues Concerning Optical networking and Equipment Essay

Issues Concerning Optical networking and Equipment - Essay Example Important network topologies and issues like, transparency, protection, routing, switching and wavelength assignment are discussed in detail. The concept of wavelength division multiplexing (WDM) and DWDM has also been introduced. Finally, the latest trends in optical communication and networks are briefly explained. Optical communication system is similar to any kind of communication system, as far as the basics are concerned. The major difference in optical and other communication models is the additional requirement of a source (for conversion of signal from electrical to optical domain), receiver (for conversion from optical to electrical domain) and use of fibre as media in place of conventional copper wire or microwave. The use of glass fibre or optical fibre features a number of advantages that make it a formidable media, in comparison to others. One of the most important assets of optical communication is the availability of enormous potential bandwidth to the tune of hundreds of GHz. The potential cannot be fully harnessed owing to electrical domain limitation. However, technologies like WDM or DWDM are evolving to optimize the available bandwidth usage. Being fabricated from glass, the fibre does no have earth loop or interface problem as are evident in electrical media. The optical communication is immune to interference from radio frequency and electromagnetic radiations or EMP (electromagnetic pulses) as they act as dielectric waveguides. There are practically insignificant radiations from fibre which enhance security of signal in a communication system. Other advantages include low weight, small size, flexible, reliable, easily maintainable, low transmission losses and cost effective. The requirement for capacity is increasing at a fast rate in the present day networks. Growth of worldwide web and Internet are the primary causes for this increase. Every four to six months, the need is almost doubling.

Which Antibiotic is the Most Effective on Bacteria?

Which Antibiotic is the Most Effective on Bacteria? INTRODUCTION Antibiotics The word antibiotic comes from the Greek anti meaning against and bios meaning life (a bacterium is a life form). Antibiotics are also known as antibacterials, and they are drugs used to treat infections caused by bacteria. Bacteria are tiny organisms that can sometimes cause illness to humans and animals. The singular word for bacteria is bacterium. Such illnesses as tuberculosis, salmonella, syphilis and some forms of meningitis are caused by bacteria. Some bacteria are not harmful, while others are good for us. Before bacteria can multiply and cause symptoms our immune system can usually destroy them. We have special white blood cells that attack harmful bacteria. Even if symptoms do occur, our immune system can usually cope and fight off the infection. There are occasions, however, when it is all too much and our bodies need some help from antibiotics. The first antibiotic was penicillin. Such penicillin-related antibiotics as ampicillin, amoxicillin and benzylpenicilllin are widely used today to treat a variety of infections these antibiotics have been around for a long time. There are several different types of modern antibiotics and they are only available with a doctors prescription in industrialized countries. How do antibiotics work? Although there are a number of different types of antibiotic they all work in one of two ways: A bactericidal antibiotic kills the bacteria. Penicillin is a bactericidal. A bactericidal usually either interferes with the formation of the bacteriums cell wall or its cell contents. A bacteriostatic stops bacteria from multiplying. Uses of antibiotics An antibiotic is given for the treatment of an infection caused by bacteria. They target only bacteria they do not attack other organisms, such as fungi or viruses. If you have an infection it is important to know whether it is caused by bacteria, and not a virus or fungus. Most upper respiratory tract infections, such as the common cold and sore throats are generally caused by viruses antibiotics do not work against viruses. Antibiotics are overused or used incorrectly there is a chance that the bacteria will become resistant the antibiotic becomes less effective against that type of bacterium. A broad-spectrum antibiotic can be used to treat a wide range of infections. A narrow-spectrum antibiotic is only effective against a few types of bacteria. There are antibiotics that attack aerobic bacteria, while others work against anaerobic bacteria. Aerobic bacteria need oxygen, while anaerobic bacteria dont. Antibiotics may be given beforehand, to prevent infection, as might be the case before surgery. This is called prophylactic use of antibiotics. They are commonly used before bowel and orthopedic surgery. Bacteria The word bacteria is the plural of bacterium. Grammatically the headline should just say What are bacteria? The incorrect usage has been included in the headline to remind readers that it is wrong and hopefully help correct an increasingly common mistake in the English language. Bacteria are tiny living beings (microorganisms) they are neither plants nor animals they belong to a group all by themselves. Bacteria are tiny single-cell microorganisms, usually a few micrometers in length that normally exist together in millions. A gram of soil typically contains about 40 million bacterial cells. A milliliter of fresh water usually holds about one million bacterial cells. Planet Earth is estimated to hold at least 5 nonillion bacteria. Scientists say that much of Earths biomass is made up of bacteria. 5 nonillion = 5,000,000,000,000,000,000,000,000,000,000 (or 51030) (Nonillion = 30 zeros in USA English. In British English it equals 54 zeros. This text uses the American meaning) Bacterial cell walls Bacterial cell walls consist of layer of peptidoglycan which is made up of many parallel polysaccharide chains with short peptide cross-linkage forming an enormous molecule with net-like structure. However, there are two different types of bacterial cell wall, which can be distinguished by Gram staining, a staining technique developed by Christian Gram in 1984 and still in use today. Before staining, bacteria are colorless. The cell walls of Gram-positive bacteria have a thick layer of peptidoglycan containing chemicals such as teichoic acid within their net-like structure. The crystal violet in the stain binds to the teichoic acid and resists decolouring in the rest of the process, leaving the positive purple/blue color. The cell walls of Gram-negative bacteria have a thinner layer of peptidoglycan with ni teichoic acid between the two layers of membranes and then an outer membrane-like layer made up of lipopolisaccharides. Any crystal violet which does not bind is readily decolourised and replaced with red safranine in the Gram stain. So cells appear red. PROBLEM STATEMENT Which antibiotic is the most effective on bacteria? APPARATUS 200 ml of micropipette, conical flask, forceps, 100 ml beaker MATERIALS Petri dish, sample of E.coli and staphylococcus, 3 different types of antibiotic which are carbenicilin, streptomycin and tetracycline, distilled water, Dettol handwash, 75 % of ethanol, agar, tissue paper VARIABLES Fixed variable : volume of bacteria Manipulated variable : types of antibiotic Responding variable : area of inhibition zone HYPOTHESIS The most effective antibiotic to inhibit bacteria growth is ampicillin PROCEDURE First of all, wash out hands with the soap or handwash. The working area is sprayed thoroughly with the disinfectant spray. It is left for at least 10 minutes, and wiped with a paper towel. An agar plate seeded with is prepared. The petri dish is labeled on the base at the edge out of name, the date and type of bacterium it is inoculated with by usng permanent marker pen. After finishing marking the petri dish, the Esterichia coli bacteria is poured by using micropipette into the petri dish on the marked labeling and distribute it evenly. The agar is taken out from 60 ÃÅ'Ã…  C oven. The mouth of the conical flask containing the agar is warmed in the flame to prevent any different bacteria from surrounding grow inside it. The agar is left for 10 minutes for it to solidify before putting the sterile disc dip into three different antibiotics. The forceps are flamed and used them to pick up disc or Mast ring. It is dip into the antibiotic solution and is placed firmly in the centre of the agar. The dish is taped securely with two pieces of adhesive tape and kept it upside down at room temperature for 24 hours. Step 1 until steps 7 are repeated by using another type of bacteria which is staphylococcus. Our hands are washed with soap or handwash and the bench is cleaned again using the 75 % of ethanol. After the incubation, the plate should be looked at carefully but do not open it. Where bacteria have grown the plate will look opaque, but where the antibiotics have inhibited growth, clear zones called inhibition zones will be seen. The diameter of the inhibition zones is measured in milimetres and the information is used to decide which antibiotic is most effective at inhibiting the growth of the bacterium. The data is collected from other members of the class who used the other bacterial cultures. PRECAUTIONS When carrying out the experiment, we should work very closed to the Bunsen burner to prevent any impurities in each apparatus that is used. Do not seal completely the upper and lower part of petri dish. Both petri dishes contain different bacteria need to be inverted to prevent the water vapour from forming at the upper site of the agar. It might affected or overshadow the inhibition zones that are formed inside the dish. Make sure our hands are constantly being wash with disinfectant before touching any apparatus. Before using any apparatus, they should be sterile to prevent any unwanted impurities to grow in the petri dish. Do not open the petri dish after incubation to prevent from infection. Explanation of the data Table above shows the area of inhibition zone of the bacteria growth on two different bacteria. Four types of antibiotics are used to be investigated which is the most effective on a particular bacteria. They are tetracycline, streptomycin, carbenicillin and ampicillin. Whereas two types of bacteria are used which are staphylococcus and Esterichia Coli. For E.coli, ampicilin showed the greatest inhibition area of bacteria growth with 10.2 cmÂÂ ². Another antibiotic that showed the closest reading is streptomycin. Tetacyclin and carbenicilin showed 5.3 cmÂÂ ² and 4.9 cmÂÂ ² respectively. This result clearly shown that ampicilin is the most effective antibiotic to inhibit the growth of E.coli. Besides that, E.coli is a gram negative bacteria. The cell walls of Gram-negative bacteria have a thinner layer of peptidoglycan with no teichoic acid between the two layers of membranes and then an outer membrane-like layer made up of lipopolisaccharides. In addition to that, Staphylococcus also had a higher inhibition zone of bacteria on ampicilin. Other bacterias have no effect as great as ampicilin which can be consider as a strong antibiotic. Staphy is a gram positive bacteria. The cell walls of Gram-positive bacteria have a thick layer of peptidoglycan containing chemicals such as teichoic acid within their net-like structure. The crystal violet in the stain binds to the teichoic acid and resists decolouring in the rest of the process, leaving the positive purple/blue color. That is why ampicilin is said to be the most effective antibiotic on both bacterias. Limitations There are some limitations that cannot be avoided when carrying out the experiment. The first one was every apparatus that we used had been sterile by the laboratory assistant. Thus we had to wash our hands thoroughly before touching anything. We even could not talk during the preparation. The problem was we carried out the experiment on the labs table, instead of using the cupboard fume to maintain the sterile apparatus. Thus, there might be some of the apparatus that we were using had been contaminated. This condition might affect the reliability of the experiment hence the expected results might not get at the end of the experiment. Besides that, we had to wash our hands by using the dettol hand soap before we start and end the experiment. We had to remove all the impurities and bacteria and that was the purpose of washing hand. The problem rose as we did not know whether we had washed our hand to the maximum cleanliness. Consequently, all the apparatus and materials that we used might be affected by our hand. This is done so that there are no infections or contaminations on the agar that might give problems later. Sources of error There are some sources of error when carrying out this experiment. Firstly, we prepared the experiment at room temperature. It was supposed to carry out in sterile medium to prevent anything from affecting during the preparation of bacteria and antibiotics. Next, the major problem that could be seen during the experiment was most of the groups could not be able to solidify their agar to the maximum hardness. Consequently, when inverting the petri dish, all its contents would be messy inside the petri dish and the disc had mixed to one another. Thus, the antibiotics on each disc also had mixed that could affected the whole result. To overcome this problem, students should let the agar solidify before inverting the petri dish. Another problem was some of the groups do not invert their petri dish before keeping it inside the incubator. This would cause the water vapour to form at the upper part of the petri dish. It would also affect the growth of the bacteria in agar. Fourth, the layer of agar inside the petri dish was too thin that caused it fell to the bottom when inverting it. Besides ruining the shape of the agar and the position of the discs in the agar, the thin layer of agar also inhibits the growth of bacteria because it lacked of nutrients. To prevent this, the layer of agar should be half of the petri dish. Further work To get more reliable and accurate result, this experiment should be repeated by varying the temperature to investigate the activity of antibiotic on bacteria. This means that increase the temperature would cause the antibiotic to act more rapidly compared to the temperature that we used before. Thus we do not have to wait for 24 hours to see the inhibition zone. This manipulated variable also do not waste the time consuming for the experiment. Moreover, as the antibiotic shows more faster effect, thus the bacteria and antibiotic should be put in separately different petri dish to prevent it from overlapping. CONCLUSION The most effective antibiotic is ampicilin. The hypothesis is aceepted. Words = 2200 Marks and Spencer: Processes of Change Marks and Spencer: Processes of Change Introduction All organizations that are currently undergoing some kind of change. Many of these programs on the changes resulting from management practices, such as culture change, business process engineering, empowerment and quality of the whole. Other initiatives, the changes are dependent on the needs of the organization to reposition the face of changing competitive conditions. A good example is the ongoing process of change at Marks Spencer. Strategic Change The term is usually reserved for such initiatives. These transitions are often related radicals in the organization, which includes strategy, structure, systems, processes and culture. Success in implementing strategic change in organizations is poor. Many simply do not understand that the implementation (which is actually turning plans into reality), and not the wording that is difficult. To the strategic objective becomes a reality, it is necessary to change the way people behave in organizations. This will require more restructuring and new systems. Background of change Faster pace of change is the starting point. Sure, companies live in times of change, indeed, more turbulent age than ever. But what was true for many years. What happened to that last, managers realized that without changes in not only miss opportunities, can kill or paralyze society. Even if an organization indulges in finally change may be too late to prevent continual arthritis of the company. Marks Spencer has been horribly damaged, not only by his lawyer about the size of its reserves, but by managing cattle demonstrated that corresponds to unravel. M S, after serving what turned out to be a strong reflection of heavy blows of its reputation and profits fell by a few weak sales. The worst thing is that Suns statistics were accompanied by anecdotal evidence bad choice of clothing for women, lack of resources, attractive shops which confirmed that the problems were not resolved. M S knew that he needed the conversion to a retailer who fleet feet, a magnet for vendors and managers, and a dynamic leader in the field of fashion. But M S was never one of those three things. During the long reign of dominance Rick Greenbury, the consolidated unnecessary functions from the past: from top to bottom, slowly and deeply conservative. Description of changes in the organization The process of change can be difficult, may be slow and painful. People by nature do not like change. Companies naturally do not like change. The question is whether we want to drive the implementation of strategic changes in our business, how much pain we are ready to commit to adopting means for change? We must first ask the reasons for changes in the business environment? There are four modes of changes that may occur in any company and be seen as the primary cause. The theory of change management Managing change in the tradition of organizational development, considers the organization of social systems, and therefore relates to humanistic element in conjunction with the mechanics of the organization. The aim is to improve the efficiency and prosperity by facilitating the organization of the development process so that eventually the organization is able to solve their problems and adjust if necessary. Therefore, in order to implement effective change, the scientist-physician must be able to adapt and apply appropriate rules to the current situation. Familiar models for inclusion in our theories in use were selected for their usefulness, adaptation and integration of members of the organization. They are listed below. Planned changes to the model of Lewin (1951) These changes in the oldest and most fundamental are that Lewins change model. It consists of three stages: melting, movement and refreezing. The publication is to reduce the peacekeeping forces of organizational behaviour. The movement involves moving behaviour of the organization and re-freezing is to stabilize the new state. Lewins saw a change in behaviour of sources in the organization. These forces are trying to maintain the standard and those who fought for change. Model of action research The classical model of action research focuses on the planned changes as an iterative process in which a preliminary examination on the organization is a way for future research and future needs. Search in the initial phase is estimated to guide research. The model focuses on the massive data collection and identification prior to any action taking place and a careful evaluation later. Emphasis is placed on the organization and work with your doctor to change all stages of the process. Business model is based on the most current research approach to planned change and is often considered synonymous with the IP (Cummings and Worley, 2005) Kotter Model According to Kotter, the plans should be established to develop appropriate stages, achievable and measurable changes, while engaging, enable and facilitate the participation of people as quickly and as openly as possible (Kotter, 1995, p. 2-3). Changes must be realistic, achievable and measurable (Kotter, 1995, p. 6). These aspects are particularly relevant to management and changes in individual groups. Prior to the organizational changes, the organization must determine what it wants to achieve with this change, why and how he knows that change is achieved. It is the address that is affected by this change and how they will react. Finally, how changes in the organization are able to achieve alone and what aspects of the changes he needs a specialist or outside help to achieve. Intervention Our diagnosis, offer interventions to deal with errors or problems and help Marks and Spencer in competition with other organizations. This list, which is not exhaustive credits towards a cultural change, but taking into account the wider context, which is defined at the beginning of the quantitative changes in corporate strategy are required. Therefore, the intervention process, which includes culture change, would be best suited for this case. Transformational change Transformational change is a relatively new organizational change. Is concerned about radical change and is essentially change the way the organization is perceived both internally and externally and how it works. This type of change would be particularly relevant to the case of Marks and Spencer, as it must radically change the way you operate in a competitive environment. Culture change The concept of organizational culture has brought a lot of research and culture, many models have been developed to define measure and observe the culture. However, little consensus about the nature of culture or to understand. Nevertheless, culture has become a very important part of the organization and activities covering a culture change have increased sharply. Schein (1990), Millward (2005) model of culture is one of the most commonly used, consists of four layers at different levels of consciousness. In the centre of the basic assumptions (unconscious, reactions uncontested guide), values (this is important) and norms (how to behave), and finally, artefacts (observable behaviours and procedures). This metaphor of culture cannot hope to capture all the elements of organizational culture, it is a useful tool in the study. Need for change To understand how organizations respond to the need for change, we must examine the organizational processes and management, organization transformation through additions, deletions or changes to the resource base leads to the attainment of these processes of change. We need to know not only what the organization which markets will come, how fast they grow, but how they do it. To understand how organizations respond to the need for change, we must examine the organizational processes and management, organization transformation through additions, deletions or changes to the resource base leads to the attainment of these processes of change. We need to know not only what the organization which markets will come, how fast they grow, but how they do it. Factors that determine the need for strategic change Organizations usually in response to changes in the external environment, as well as the development of competitive advantages in the organization. External environmental factors, including: Social factors Such as changes in demographics and purchasing habits of consumers. Legal factors Legal pressures that force organizations to comply with the law changes, for example, in response to environmental legislation. Economic factors Relate to the booms and declines in economic activity in general, changes in interest rates, inflation, etc. Political factors These are related to wider policy changes for example the government to take a particular line of the privatization / role of government in society. Technological factors Technological aspects of technological advances such as developing new methods based on point of sale by the company. In addition to these factors, he slept a significant impact on the organization, making competition. Slept analysis is an analysis of the major changes in the environment of the organization. This is sometimes called environmental scanning. Managing change is a key aspect of how the organization responds to changes in an appropriate manner. Todays managers believe that in the future, organizations need more leaders who can use the talents of the organization in achieving its objectives, the development of a culture that believes change as an opportunity rather than a threat, regularly invent the organization, effectively planning and implementing change. To succeed in this environment, managers have to do the right things in the existing well-defined procedures and limitations. Predictable and stable environment reduces the need to mobilize the organizations capacity, flexibility, creativity and innovation. The environment has changed radically, and successful organizations and their managers should behave differently. Managers in todays environment are needed to transformation of the organization, to develop good relationships with internal and external stakeholders, run horizontally and vertically, and not the entire culture lines enable employees and the development of networks and alliances. Stakeholders in developing a strategy change Stakeholders are those who have direct interest in the organization and may be beneficial, and harmful to the organization if not properly treated if a policy is adopted in order to keep the company and they should also participate in company affairs and decision making. The system is planned in this direction in which we can pass our message to all actors in society and be in the best interest of the latter. Some of it is also relevant for people who do not want to change or resist change. The behaviour of these people also consider. Resistance to change Responses to organizational change initiatives are no different. In the beginning there is a small proportion of the early adopters those who want to participate, because I just changed a breakthrough that will lead to better conditions. Most of the people affected by the initiative of the changes will be far less enthusiastic than the early adopters, but over time they will eventually accept and adjust to it. Finally, the group will not be very resilient, many of whom will never adapt to the changes in place. This range of behaviour results from a normal distribution. It is a natural phenomenon intuitively understood by most managers of change. Unfortunately, though perhaps unconsciously, to understand the phenomenon, these managers often do not use this knowledge to better organize an effective change. The aim is to adopt the first to develop their support and consciously use their influence to speed up the most reluctant to change. It is important to understand that they do not reflect the impact of hierarchical position. Leaders are natural leaders and respected functional experts who are well connected. They are nodes in the social, business, politics and communications networks, and their sphere of influence goes beyond the scope of their parent organization. While these influential illustrate its support for the changes, they are a marketing tool more powerful than any message issued by the office of managing change. Strategies should be performed on the leaders of high or medium, the goal is to transform them into the first users, and use its influence over the end of the interest or commitment. For those who cannot be pulled forward or to the small force, aims to accelerate the speed of their adaptation to help them better understand and prepare for the consequences of change. It is also focusing on people who are able to adapt, but because of its unique combination of knowledge, skills or abilities, but a significant contribution. Some people will be unwilling or unable to adapt to change. They are already able to demonstrate their acceptance and respect for a change, otherwise, may suffer the consequences clear. Include initiatives that will affect change, how it will affect them and what their reactions might be important for the success of the strategy changes. When an organization brings new things about people, there will be problems. Participation, involvement and open, early, full communication are important factors. How to tell change to people The workshops are very useful process to develop a common understanding, methods, principles, methods, systems, ideas, etc. Surveys are useful to repair the damage and lack of trust among employees if you allow people to fill them out anonymously, and provided that publish and implement the findings. You cannot force change individuals and teams must have the right to seek their own solutions and responses, the facilitation and management support, tolerance and compassion for managers and executives. Management style and leadership behaviour are more important than intelligence and the political process. Employees must have confidence in the organization. A leader must listen to and work with these ideas, or change can be very painful, and soon will be lost in the process. You may also find that the main problem is the resistance of the people and defence of someone who is in the organization, what you do. After this challenge, you can begin to compare what is happening with what the organization intends to do (mission, values, goals, priorities, targets, key performance indicators, process measures), as people feel things (marketing, maintenance workers, morale and attitudes ) as well as customers and suppliers feel too much (in fact, go out and find clients and former clients in particular). Follow the protocol is very difficult you have properly with people and explain who you are and what you do. Be polite. Respect the people more than usual; because they are sensitive, it is understandable. The framework for change management at Marks Spencer Marks Spencer has been under pressure to change the external economic factors and not yet answered correctly. It is for this reason that the approach proposed amendment is necessary to initiate and implement change is being driven by the management of physician (s). Using current models and theories of change management in the organization development, proposed a framework for planned changes that could be used by Marks Spencer. Context of Changing First, in the context of the situation to be addressed in order to develop appropriate methods of change. This can be done in three dimensions: The volume changes Incremental change to solve specific problems such as lack of communication and low customer satisfaction Quantum amendment to change the basic functioning of organizations, including the structure and culture Degree of organization Over-organized where policies are too rigid for effective action due to poor communication, conflict avoidance, etc. Sub-structured where there is too little regulation for the effective operation due to lack of direction and coordination structure. Domestic vs International Cultural differences, especially between Eastern and Western societies, for example, Asian countries tend to be hierarchical and North America deal with individuality. It can be difficult to implement change, which encourages openness among employees when it is not viewed positively. In the case of Marks and Spencer, the magnitude of change is that major changes in the quantum of culture, structure and strategy must be addressed. They will be included in the applied intervention. They are also highly organized society with the management system now that he is honoured to be part of the overall problem. Although the system successfully in the past, is steeped in ancient culture and able to adapt to a redesigned image of Marks Spencer. Therefore, the process of change at Marks Spencer will focus on softening of the structure. General review, Marks Spencer, will be treated as a citizen of the operation of this case, since closed down its operations in Europe and North America sold its franchise stores in Hong Kong. The model change is composed of seven steps to help developers to the key issues of transformation. Activities focus on people, leadership, trust, vision, empowerment, celebration and institutionalization. Despite the emerging linear stages can occur simultaneously. Effective communication is the mortar. There must be open and honest communication in every step of the process, and communication needs to combine these steps together. Nothing can destroy the effort to change sooner or permanently, that poor communication. Here are the steps for effective transition. Assessment and solve human problems Contractor changes need to invest time and effort to understand the problems of people does not appear in place of those who suffered, and then practice the golden rule of treating others as they would be treated. Exercise strong leadership in the organization Without strong leadership, positive change will not. Leadership can no longer be the domain of a few organizations all the staff responsible should do what it takes to achieve organizational goals. This is especially true when change must occur. Many must step in and assume leadership. Spreading leadership and decision-making responsibilities, inspires and motivates everyone to play a role in implementing the changes. Building trust in the leadership Confidence is simply the belief that it would suffer if threatened. Obviously, the level of mutual trust between labour and management or between supervisors and subordinates affects the health of the organization. Clearly articulate the vision to all If you want to change, please explain the reason and purpose of fundamental change. People cannot have a real idea of where the organization is or what problems it faces. You have to tell them. They need to understand the purpose for the desired result. Be prepared to answer these questions: What is the problem? Who said that? What happens if you do not change? Creating an helpful environment Organizations can do everything possible to prepare the ground for change in response to the concerns of people in order to demonstrate strong leadership, building trust, formulating a vision all, that is, but to create an environment to enable success. Honest answer is that you can get almost as much as you want to manage anything else of a turbulent, messy, chaotic nature, it is not really manage it, talk with her. It is a question of leadership is one of management skills. The first thing to do is jump in. You cannot do something outside. A clear sense of mission or purpose is essential. A simple mission, the better. Building a team that can work hard and one of them is the team leader. Pick people with relevant skills and high energy levels. Youll need two. Set flexible priorities. You must have the ability to drop what youre doing and tend to something more important. Treat everything as a temporary measure. Ask for volunteers. You will be surprised that arises. You will be pleasantly surprised what you can do. Find a good boss or team leader and stay in his way. Conclusion In concluding this report, we can say that effective reforms introduced to the strategy are to maximize the huge returns if these changes are well managed. In this report, and Spencer takes on the characters thinking and different models are also discussed to show the strategic shift from Marks Spencer, which is a leading company in the UK, but suffered from some activities for that has to change, and finally models Kotter and Lewins, a representative of the role of stakeholders that their existence in the affairs of the company is very necessary to be able to join in their decisions and At last appropriate model is also developed, which will provide guidance for better performance.

Cauvery River Dispute - The Cauvery river dispute is one of the longest river dispute today. The dispute began in 1974 when the 50 year old agreement between the Karnataka and Tamil Nadu Collapsed. The Cauvery basin covers majorly 3 states and 1 UT – i.e. it originates Talacauvery in Coorg in Mysore state and then flows to Tamil Nadu, Kerala and Puducherry. But the Use and development of Cauvery Waters were regulated by agreements of 1892 and 1924, which were solely between the Mysore and Tamil Nadu. According to the Karnataka government the 1924 agreements states the discontinuation of the water supply to Tamil Nadu after 50 year. In 1990, SC directs centre to constitute Cauvery Water dispute tribunal (CWDT). The tribunal heard both the parties and reached a conclusion that Karnataka should release 205TMC of water to Tamil Nadu, every month. Karnataka denied the ruling and argued that it is impossible to implement the decision as in failed monsoons many areas of Karnataka are left without water. In that case they have to transfer water at the cost of their own people. In August 1998 the Centre constituted the Cauvery River Authority to ensure the implementation of the CWDT. The Cauvery Water Disputes Tribunal (CWDT) announced its final verdict on 5 February 2007, after 16 years. The Tribunal made the two agreements of 1892 and 1924 functional. According to the verdict, Tamil Nadu was supposed to get 419 billion ft ³ of Cauvery water while Karnataka was supposed to get 270 billion ft ³.
