Animal testing should be banned essays

Animal testing should be banned essays When picking out your mascara or eyeliner, do you even stop to see what kind of makeup you are using? You could be supporting animal cruelty and not even know it. Today many makeup products, such as mascara, are being tested on animals. Helpless and defenseless animals are being performed on for different types of experiments all around the world. Most of the things being performed in these labs you could never imagine one human being doing to another. I believe that animal testing should be banned because it is cruel, not very reliable, inaccurate, and is proved to be unnecessary. Animal testing is arrogant and incredibly cruel. Like us, animals can feel pain and fear, but also excitement and satisfaction. Close contact with animals shows that they look forward to some extents, and can clearly get a lot of enjoyment from their lives, be it from basking in the sun, exercising, eating favorite food, or interacting with others, as in playing and mutual grooming. Certainly animals don't have the same abilities as humans. They can't talk, write books or drive cars, but neither can some humans. We don't ask how intelligent a person is before we decide whether to eat them or experiment on them. Regardless of intelligence, their life still has value to them. Use of animals clearly violates animals right to live without suffering pain or emotional distress. A range of household products including cosmetics and cleaners are routinely tested on animals to determine how safe the products are for human use. Some of these animals are subjected to pain in tests of skin or eye irritancy; others are killed while establishing the lethal dose of chemical products. In animal experiments, animals can be burned, cut, mutilated, poisoned, turned into drug addicts or alcoholics, given diseases such as cancer or arthritis, crippled, blinded, starved, and brain damaged. Most of the time the animals are denied painkiller, for fear of affect...

Dances With Wolves Essays - Dances With Wolves, Films, Dunbar Dances With Wolves Dances with Wolves April 5, 1863 I have arrived at my post and found it to be completely unmanned. Fort Sedgewick appears to have been abandoned for some time. I do not know what has happened to the men that were posted here, but I am anxious to hear from someone. Fort Sedgewick is my post, but I have no one to report to. I don't know what to do. I can only communicate if I leave, and I don't want to abandon my post. I have assigned myself cleanup duty, and will attempt to restore the supply house. It is a tough job for one man but I have plenty of time. All is quiet on the frontier. Lt. John J. Dunbar, U.S.A. April 25, 1863 Today I made contact with an Indian. He is the first man I have seen since my being here. He tried to steal my horse, when I appeared I spooked him and he ran off. I am sure there are many more in the area. I will begin to prepare for another visit, if troops don't arrive soon, all may be lost. I have decided to ration my goods. The missing replacement should be here anytime; it should not be too much longer. I have been patrolling the area day-to-day and have found nothing. Except there is a wolf who seems to interested in the activity here. If he arrives again tomorrow I will name him Two Socks for the milky white socks on both front paws. Lt. John J. Dunbar, U.S.A. May 20, 1863 Many things have happened since my last entry. The Indians have come to visit a few times and our meetings are friendly, though they are frustrating due to the language barrier. It is always the same two men who come; six or seven other warriors accompany them. One of them must be a warrior leader, he is very strong and fiery. The other is very quiet and I think wise. We have learned to speak a few words of each other's language, but not many. I also have visited their camp briefly. I was very excited to see how they lived and I enjoyed myself. I smoked their pipes with them, sat around the campfire, and then was escorted out by the quiet Indian. I look forward to another visit with my neighbors. Lt. John J. Dunbar, U.S.A. June 1, 1863 Today great progress was made with my neighbors. They have a white woman living in their camp named Stands With A Fist that can interprit my conversations with the Indians. I now know the name of the quiet Indian is Kicking Bird. They have named me Dances With Wolves. I now know what questions the Indians are asking me and the same for them. The quiet one and I have become good friends. He is constantly asking me if more white man will come into these lands. I just cannot bring myself to tell him. I feel that our relationship will only grow stronger. Lt. John J. Dunbar, U.S.A. June 29, 1863 So much has happened since my last entry; I don't know where to begin. I now can speak the language of my neighbors thanks to the teaching of Stands With A Fist. It took me quite a while but I am pleased with how fast I am learning. I have been spending much more time with my neighbors and I have been able to learn much more about them. Last conversation Kicking Bird and I had, he asked again about more white men coming. I told him there would be more white man than the stars; the color went out of his face and he looked lifeless. I am sorry for telling him. Lt. John J. Dunbar, U.S.A.

Diversity in Organizations Research Paper Example | Topics and Well Written Essays - 750 words

Diversity in Organizations - Research Paper Example It is evidently clear from the discussion that workforce is the basis of success of any given organization. Much as there are other factors of production to consider in determining the likelihood of success of any organization or business entity, human capital is the most significant. This is because; no operations can become successful regardless of the capital input, unless they are well managed and implemented. Thus, the need for adopting a flexible human resource program that integrates diverse cultures and personalities within the operations of the organization is paramount. The encompassment a different people, from different backgrounds in religion, socio-cultural activities, education, and exposure ensures that the organization can uphold variant ideas, opinions, and judgments. These are the basis of development. Owing to the fact that teamwork is the basis for success of any given organization, diversity comes in handy. Where diversity is non-existent, the individuals involv ed cannot interact and share ideas and opinions freely. This means that there is low or no chance of devising new ways of doing things. It is through the free interaction of individuals and their teamwork attitude that creates avenues for innovations and inventions. Various methods can be adopted to enhance diversity climate in an organization. Education that entails equipping the management team with relevant and diverse training skills is one such method. This serves to ensure that the management team is better placed to adopt different individuals and incorporate them in their labor force. Such training enhances the management ability of ensuring every member of their team feels appreciated and equally important, not withstanding their differences in personalities, cultures, religious backgrounds e.t.c. The establishment, enforcement, and implementation of a set of code of ethics is yet another method. The basic step in achieving this is through the recruitment of individuals fro m different spheres of life. Exposure, through establishment of equity and accountability, as a core value of the organization is another method that applicable in enhancing the climate of diversity in an organization. This ensures that all the individuals are treated equally, regardless of their gender, origin, race, religion e.t.c. any group, committee or panel formed to undertake different tasks for the organization should be representative of the different personalities in that organization. Each group or individual should feel well represented in that formation. This goes a long way to enhancing respect and cooperation from all the individuals in the organization. There are three procedures followed to establish diversity climate at a work place. The first is the moderate open- minded change, where some basic rules are established in work place to foster teamwork, flexibility, and diversity. At this stage, the workers are promoted solely based on merit and performance. Such rul es as those guiding promotions are established and implemented by the policy makers. However, the problem associated with this is that not all aspects of diversity are implementable through formal rules. The second procedure is the essential change stage, where the organization adapts measures beyond formal rules to guide the achievement of diversity in the organization. At this stage, even though two members of the same affiliation are better placed to be promoted based on their performance, an allowance for equity is created by promoting another individual of a different affiliation. The last procedure is the revolutionary change, where the short-run and the long-run needs of the organization come into play. Under this stage, the organization establishes equity and diversity in the short-run, while buying time to consolidate a system that will afford automatic flexibility and diversity

Determine the best deal between two different computers Essay

Determine the best deal between two different computers - Essay Example Dell has its own pros and is an amazing product, but when it comes to buying a computer, Mac takes the first place because when compared to Dell it has more pros. There are many things I have discovered in my research and would like to share them all with you. First and foremost, let us consider the software used for both the computers. Since minority uses Mac, therefore most software manufacturing companies find it prolific to manufacture software that can be used on personal computers like Dell, rather than those that are used on Mac. For this reason, we can find a whole range of software for personal computers like Dell but we do have the luxury to choose software for Mac as well. There are many specialized software for Mac as well. People who are in some way linked with media find Mac better than Personal computers like Dell. Mac offers great technical support for such people. (123helpme.com, 2011) Also, the factor regarding price comes, and people argue that Mac is more expensive than personal computers like Dell. In this case, people only talk about the initial costs incurred. If we consider the price that Microsoft charges if the software is being used on more than one personal computer. Mac does not have any charges for client access on a server. (123helpme.com, 2011) Plus, there is quite some difference between the usage of Mac and Dell. Some argue that Mac is not as easy as personal computers like Dell. However, this is just a myth. Mac is as easy for usage as Dell or any other personal computer. Furthermore, Windows can run on Mac easily but no personal computer can run Mac natively. Some even say and have observed that Mac is way faster than the rest of the personal computers. (Make use of, 2009) Also, on personal computers there is a massive threat of viruses. On the other hand, the Personal Computers are recommended to have antivirus installed in them. Yet, it still gets virus and gets

The International monetary and finance structure Essay

The International monetary and finance structure - Essay Example The appreciation of the Euro can be attributed to increasing trade surpluses in the Eurozone countries for the past years and the low rates of inflation in the Eurozone countries. For the past years, countries in the Eurozone such as France, Germany and the other seventeen countries have experienced an increase in the amounts of exports compared to imports than other countries. For instance, in 2013, the Euro Zone exports accounted for about 13.2% of GDP while import stood at 12.6% leading to a 2.7 current accounts deficit (De La Dehesa 4). On the other hand, during the same year, U.S. exports accounted for about 13.5% of GDP while imports stood at 16.2% leading to a 2.7 current accounts deficit (4). For this reason, the Euro has been gaining strength especially in the last six years due to better current accounts compared to the U.S. Conversely, the move by the European Central Bank (ECB) to wipe out about â‚ ¬1 trillion two years out of the economy of the Eurozone in a move to withdraw loans taken by banks during the debt crisis is another significant factor that has led to a higher appreciation of the Euro relative to other world currencies (De Grauwe and Paulson). In addition, De La Dehesa argues that short-term rates in the U.S. react mainly to trends in the U.S.’s equity markets. He goes ahead to say that, for this reason, short-term interest rates have a higher impact on exchange rates in the Euro area unlike in the U.S. For instance, from a historical perspective a rise of 100 basis points in U.S. short-term interest rates leads to an appreciation of the dollar by 1.7% compared to 5.7% in the Euro area (De La Dehesa 4). For this reason, De La Dehesa conclude that the Eurozone economy is more open than the U.S. economy. The Yuan has been appreciating in recent past due to the massive growth of the Chinese economy. China has grown to become the second-largest

factors affecting saccharomyces cerevisiae

factors affecting saccharomyces cerevisiae Chapter 1: Introduction Research Questions: What is the effect of differing temperatures on Saccharomyces cerevisiae population growth? What is the effect of differing pH levels on Saccharomyces cerevisiae population growth? What is the effect of differing glucose concentrations on Saccharomyces cerevisiae population growth? The yeast Saccharomyces cerevisiae is a single celled fungus that reproduces asexually by budding or division. It is one of the most well studied eukaryotic model organisms in both molecular and cell biology. S. cerevisiae is a very good type of yeast for biological studies owing to the rapid growth (doubling time 1.5-2 hours at 30 Â °C), the dispersed cells and the ease of replica planting. Moreover is a non-pathogenic organism, so can be handled fearlessly with only little precautions. Also large amounts of commercial bakers yeast are available with result being an easy and cheap source for biochemical studies. S. cerevisiae has round to ovoid cells between 3-8ÃŽÂ ¼m in diameter. 1.2 Respiration In biology, respiration is defined as: the process by which the energy in food molecules is made available for an organism to do biological work (Kent, 2000; p.100). It is also called Cellular respiration. This process of cellular respiration happens in every living cell as it is the only way to obtain energy in a form that will be usable for the cell, so it can carry out the functions of movement, growth and reproduction (ibid). The food in yeasts must be obtained as they cannot produce it on their own. For yeasts, a very good source of energy is sugars. All strains of S. cerevisiae can metabolize glucose (a hexose sugar), maltose and trehalose. 1.3 Types of Respiration There are two main types of respiration that take place within a cell: Anaerobic respiration (without oxygen) and Aerobic respiration (with oxygen). S. cerevisiae can metabolize sugars in both ways, but in this research the cultures of yeast were exposed to air hence to oxygen, so aerobic respiration was mainly the way that yeast cells grew and reproduced. 1.4 Enzymes Thousands of chemical reactions are carried out within a cell. These reactions most of the times occur in a very slow rate. For that reason living organisms make biological catalysts which are called enzymes and speed up these reactions. Enzymes are globular proteins which act as catalysts of chemical reactions (Allot, 2007; p.18. Also cells can control which reaction occurs in their cytoplasm by making some enzymes and not others. Enzymes achieve to increase the rate of a reaction by decreasing the activation energy (the minimum amount of energy required for a reaction to occur) (Greenwood. Et al. 2007; p.167) of the substrate or the substrates, when binding to the activation site (Greenwood. et al. 2007; p.114). Enzymes are sensitive molecules with very specific structure which enables them to carry out specific reactions. This structure including the active site can be damaged by various conditions and substrates. This damage is called denaturation and is usually permanent for an enzyme and if denaturation is occurred the enzyme can no longer carry out its function. As a result when enzymes are required to catalyze a reaction, is necessary that they have appropriate conditions. Different enzymes have different ideal conditions called optimum. The factors that affect the enzyme activity are: the temperature, the pH, the substrate concentration. The effect of temperature, pH and substrate concentration upon the enzyme activity which affects the growth of S. cerevisiae yeast cells are studied in this research. 1.5 Effect of Temperature As the temperature is increased in an enzyme-catalysed reaction, the rate of reaction is increased up to maximum in a specific temperature. This is called optimum temperature. The optimum temperature of Saccharomyces cerevisiae is 30o- 32oC. Above this temperature the rate starts to drop rapidly. This is due to the high energy that causes vibration inside the enzyme with result the bonds which maintain the structure of enzyme to break. This causes denaturation and the active site can no longer fit the substrate. 1.6 Effect of pH (hydrogen ion concentration) Most of the enzymes operate effectively in a small range of pH values. Between these pH values there is an optimum pH value in which the enzyme activity is the highest. The optimum pH of Saccharomyces cerevisiae is 5.5. Acids and alkalis cause denaturation of the structure of the enzyme by breaking mainly hydrogen and ionic bonds with result the substrate cant fit the active site. Furthermore the charges of the amino acids within the active site are affected by pH changes, so the enzyme is not able to form an enzyme-substrate complex. Above and below the optimum pH the enzymatic activity hence the rate is reduced considerably. 1.7 Effect of Substrate concentration In an enzyme-catalysed reaction the rate increases in direct proportion to the substrate concentration. The optimum glucose concentration of Saccharomyces cerevisiae is 2%. At low substrate concentrations, the rate of enzymatic activity increases sharply as the substrate increases. This occurs due to the more frequent collisions between the substrate molecules and the unoccupied active sites. On the other hand, at high substrate concentrations the biggest part of the active sites have been occupied with result when increasing the substrate concentration there is little effect on the rate of enzymatic activity. 1.8 Purpose of the research The purpose of this research that is carried out to examine the growth of S. cerevisiae yeast cells in different factors and various conditions is not so in order to discover which are the optimum conditions in each factor (as this species of S. cerevisiae is very well studied and examined professionally because of its usage in food industry) but to examine in real conditions and not theoretical ones how altering the environment of a cell affects the way its enzymes work and help the whole cell to live and divide in all of the previously ways that were mentioned in the introduction part.

Essay --

The Roman orator once stated, â€Å"Outside of my home is where my life is made† or in the Roman language he said, â€Å"Ex mei domus est ubi mei vita factavest†. He understood that most of our lives take place other than inside our homes. Also, it is important for people to enjoy the natural environment for several reasons. First of all, around the world lumberjacks are cutting down trees to make room for houses, office buildings, movie theatres, malls, and much more. The company who has told these lumberjacks to do this hideous deed does not know that by carrying out this action, the company and its employees are taking away millions of animal habitats. It varies from the Bobcat to the Grey Squirrel and animals like humans need shelter, food, and water to survive but without it, they die. People being able spend time in the outdoors will see what mankind is doing to these innocent little animals and might consider not to demand things that might hurt someone else. They will soon appreciate the natural environment and what Mother Nature has to give to the world. Another reason is that the p...
