From trip 1, it seems that if we use automobile, time and cost are more than using general aircraft. While Automobile takes 12 hours to reach BAB from BNA, it is only 6:30 hours in terms of General Aircraft. But Automobile takes more costs from General Aircraft. It is $3939.41 for Automobile and $2,366.76 for General Aircraft. From trip 1 it is clear to us that General Aviation Aircraft is better than Automobile. From trip 2, it seems that if we use general aircraft, it takes more time than using Commercial Aircraft (non-stop). While General Aircraft takes 6:30 hours to reach BAB from BNA, it is only 3:00 hours in terms of Commercial Aircraft (non-stop). However, it takes little more costs from General Aircraft. It is $2,366.76 for General Aviation Aircraft and $2,997.22 for Commercial Aircraft (non-stop). Although Commercial Aircraft (non -stop) costs a little bit more than the General Aviation Aircraft but Commercial Aircraft (non-stop) saves more valuable time for executives. Therefore, Commercial Aircraft (non-stop) is better than General Aviation Aircraft. From trip 3, it seems that if we use general aircraft, it takes more time than using Commercial Aircraft (one-stop).

Dominos Pizza in Mexico Case Study Example | Topics and Well Written Essays - 1250 words

Dominos Pizza in Mexico - Case Study Example One thing that has been common in all the above mentioned companies is that all have been very successful in capturing their audiences. Their success story hasn't only revolved around the advertising for their company but a complete team effort, hard work, determination; the will to become the leading fast food chain in the world has made them reach the zenith. If we start to compare Domino's with their opposite number, McDonalds, we will come to know that their respective road to success has been full of challenges and somewhat quite similar too. First and for most, the two companies came into existence when no such food company existed. They had to start from scratch and had to make the people feel the importance of their brand and for that the most crucial and important part was team building.( Tom Monaghan,1986) They had to search for people who were determined, fresh and eager to learn in collaboration with their respective companies. Secondly, once established the two companies had to maintain that vibe and hunger ness for the people to buy their product by launching new food items that would surround and match the eating brain of a human being. They had to keep the quality of the food as their first priority in order to attract the customers. (David A Hanks, 1989) Moreover, both Domino's and McDonald’s had to change their advertising setup when launching them selves internationally. They had to grab the local market and the local people with their innovative strategies. They also took under control the prices of their products in accordance to the economy of that country and in accordance of an average person's reach. All and all, Domino's and McDonald's are quite similar in nature excluding their distinct and unique products and because of the adaptability in all cultures; Domino's has been able to stamp their authority in the global market throughout the world. 2. Domino's rely on the work hard, play hard culture where they set themselves tasks and standards and then work collectively to succeed in those tasks. (Tom Monaghan, 1998) They do not compromise on the quality of the food and in the appearance of their company. That is why, where ever they go, in which ever country they enter, they keep their tag line, their presentation, their rules and regulations and the quality of food at the top. For them, a customer’s satisfaction is their satisfaction. (Georgia Brazil, 1986) One important thing that Domino's has followed throughout the years is that they have kept the interface of their outlets identical. This has helped them in reaching far off areas where the people used to recognize Do mino's not by their name, rather by the companies’ logo, ‘The Domino's logo’. Another area that Domino's has clicked is by hiring those people as employees who could work in their corporate sectors. (John A Jakle, 1999) Such people are aware of the local food standards and know what the customers require. In this way they can help the higher officials in the company to make them understand the psychic of the food of the local residents of that area. Another aspect that Domino's has taken into account is that in order to nullify any problems in their administration, Domino's regularly takes their managers working across the globe to stores for training. (James Mac Nair, 1987) There they are given lectures on how to run a franchise and what is

The Most Effective Antibiotic On Bacteria Biology Essay

The Most Effective Antibiotic On Bacteria Biology Essay 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. 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. RESULTS Antibiotic Diameter of inhibition area/ cm Inhibition area / cm ² E. Coli Staphylococcus E.Coli Staphylococcus Tetracyclin 2.6 3.0 5.3 7.0 Streptomycin 1.6 2.0 8.0 3.1 Carbenicillin 1.5 3.5 4.9 9.6 Ampicillin 3.6 3.8 10.2 11.3 Control 0 0 0 0 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 cm ². Another antibiotic that showed the closest reading is streptomycin. Tetacyclin and carbenicilin showed 5.3 cm ² and 4.9 cm 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

The Therapeutic Value of Charlie Chaplin Essay -- Biography

The Therapeutic Value of Charlie Chaplin Pat Barker's Regeneration represents a part of history for the First World War. Regeneration is an antiwar novel held together by people, places, and cultural references. Charlie Chaplin is a cultural reference used within the novel. Barker refers to Chaplin on page 60 in the novel. When the wounded and dysfunctional soldiers watch a Charlie Chaplin film at the Craiglockhart War Hospital. During the war Charlie Chaplin films were therapeutic for the soldiers, and showing one of his films helps develop the theme of therapy that occurs throughout the novel. Even though Chaplin was unable to participate in the war, he helped boost the morale of the soldiers that were in it. Barker utilizes Chaplin as a cultural reference to show that good morale is needed to help the progress of the patient's therapy, but true recovery takes more than just a film. Charlie Chaplin faced public backlash with his stance on World War I. In The Importance of Charlie Chaplin, Arthur Diamond says, "a British citizen had chosen not to leave the United States to fight for his native country" (58). Chaplin's actions caused British audiences to have mixed feelings about him. They loved his films, but disapproved of his non-participation in the war. However, British representatives said that Chaplin was more valuable as an entertainer than an infantryman (Diamond 58). So while the public disagreed with his non-participation, the British government backed him up. In early 1917, the United States knew that Chaplin was a British citizen living in the U.S. and that Chaplin was part of the support system for their side. However, their attitude changed when the United States entered the war after the Germans sank th... ...haplin's irreverent humor plays a big role in developing the theme in Regeneration. Without his comedy, many of the patients at Craiglockhart War Hospital would not have been able to look past and overcome the real aspects of the war. Chaplin found a way to make his audience laugh when they were filled with horror, and he opened the minds of the soldiers, which had once been closed like a shell. Works Cited Barker, Pat.

I plan to conduct my research on and if animal rights organizations have gone too far in promoting a vegetarian diet? And those who do not encourage this and the importance that meat has. Is an imal rights organization taking it too far, when it actively encourages a vegetarian diet as a way of life?Of course it’s taking it too far by ignoring the value of nutrients that meat can offer our bodies. II. Of course it’s taking it too far by promoting a diet that should have nothing to do with animal abuse. III. Secondly, they ignore the value of nutrients that meat can offer our bodies that can lead to healthier muscle growth. IV. A solution to this would be to find a different method that is least painful for the animals we kill to eat. V. A second solution would be to let others eat what they want, and focus more on stricter laws.To actually putting a stop those who are abusing these animals. VI. I agree that everything on earth is for the utility of humanity. But that doesn’t give any one the right to abuse, or be cruel towards an animal. We should focus more on stricter policies, and stopping does who make these animals suffer pain. Just because an ani mal is killed to provide meat, is no reason to turn vegetarian. Humans have a right to eat meat. The abuse has to stop, so that we are provided with a healthier meat.

Adulthood by Nikki Giovanni

Adulthood by Nikki Giovanni BY urnerl 203 Umer Rehman Professor : Boisson English:200 Adulthood Nikki Giovanni wrote many peoms , basically between the time of 1960s and 1970s. At the time of depression. Adulthood is one of the peoms written in the same time as well. Adulthood is a short story about a girl and which shows her childhood and gradually coming into adulthood. In this peom the Narrator tells us at many places about the economic status of the little girl in different ways.In the beginning â€Å"when i was a little girl in Indianapolis†, Indianapolis is a subarban area, not a good economy there. It has small towns there and so Just by this we can figure out that girl is not from a rich family or place. in the next line it says â€Å"sitting on the doctors porches with post dawn pre debs†. Sitting on the doctors porches refers to someone sitting on the steps and doing nothing. It shows as someone who has no Job or has nothing mportant to do, so they Just sit an d look around.It describes how the place where girl lives has people, who have not much t do and so they sit on door steps and kill time. when we read the next two lines of the peom, where is says â€Å"i wondered if life would give me a chance to mean†. it relates with the fact that she is sitting there doing nothing and thinking she is worthless, and hoping life gives her a chance to make herself mean something important rather than sitting here.Narrator also mentions the slang language being used again and again in the poem like â€Å"usta† and the informal way she uses like â€Å"and other bullshit stuff'. This potrays her surronding , how and where she is brought up, as the economic status is not good and we see where she Ilives is not with many educated people so the slang language is used alot. They talk about stuff which is not important while sitting and conversing,shows kind of place and people there are.
