Run Flat Tyres Assignment Example | Topics and Well Written Essays - 3500 words

Run Flat Tyres - Assignment Example For any car to perfectly work then it entirely depend on; how large the air chamber between the rim and the tire is, the pressure that the tire can support and the strength quality of the tire. In the reflection John & James (2000) thinks that one big technology that has total revolutionized the car industry is the Flat tire technology since this is a type of tire that losses air very slowly that one would not even notice thus enabling the pressure of the tire to be substantially low enough to cope with the new situation. These strong internal construction that is able to withstand the weight of the car in case of a deflation. This type of tire has the capability to take a car even up to a distance of 80km at the speed of 80km/hr. Most of us have probably been faced with most of the that are associated with flat tire; maybe you missed a date, had to change a tire while being rained on because you didn’t want to miss an appoint meant, or your car tire went flat in the middle of nowhere then it’s for the same reasons that made the stake holders to come up with a tire system that could solve most these problems associated flat tire. In their review Anson & Mike (1998) believes that the idea of coming up with a flat tire system dates back to as early as the early 1980s. It was at this time when this idea was applied in a practical situation. This idea then had been applied on Porsches 959 sports cars. The designer of this car built it to be able to cruise to a top speed of 200mph and thus he recommended tire system that would not disintegrate if it lost air pressure at this high speed it was meant to reach. This idea worked for this car and this was what would give the engineers the needed confidenc e to further look into making these tires for all the cars. According to their writing Anson & Mike (1998) they say that the run flat tires were first commercially produced in the year 1935 though quite different from today’s design since it had an

Aspects of the Fundamentals of Speech Class in APA Style Essay

Aspects of the Fundamentals of Speech Class in APA Style - Essay Example The exchange of thoughts, messages, or information by speech is very crucial in our daily lives.The American Heritage Dictionary of the English Language states that communication is â€Å"The art and technique of using words effectively to impart information or ideas†. Speech is used in our everyday lives, whether or not we realize it. It is not something that we learn in school and will never implement in real life. One who can communicate more effectively will more likely gain better success in all areas-personal, academic, and professional of life. Speech, or public speaking, involves organizing ideas, researching these ideas, and presenting them to others. We all have many, many ideas about what we would like to speak about. The difficult part is narrowing it all down to one idea, or topic. The best way to do this is to choose a topic that you are familiar with and interested in. Use resources such as magazine articles, books, newspapers, television shows, conversations with people, etc. to help gain ideas. Knowing how to choose the best topic, narrowing it down, and researching (learning more about various subjects) are skills that can improve my daily communication such as talking with a friend, discussing a topic with a professor, or trying to land a job with an employer. employer. Fundamentals of Speech 3 Determine what the purpose of your speech. Will you be speaking to inform and to offer information or will you be writing to try and persuade Informing is to give facts and information without adding personal opinion. Persuading is to try and change the attitudes and thoughts of your listeners in order to get them to act upon what you have said in your speech. The skill of delivering information in a manner that is interesting yet informative and the power of persuasions helps my listeners to believe what I say. Speech helps me to be a better storyteller and makes me more social in my personal life. As I can communicate better verbally, I am more secure about myself and others want to listen. Professionally and academically this knowledge of delivering information and to be able to persuade others using speech is an extremely effective tool that will lead to my success whether I am in class, at an entry level position, or an executive position in the workplace. The best speeches contain your own experience and knowledge of the chosen topic. Use information from materials such as books, magazines, reference materials, etc. from various sources. Libraries contain a wealth of information. Interviews, the internet and visiting various locations can provide the necessary information. Be sure to take good notes and to give credit to the author of the information that you will be using. Researching and listing references (or where you got the material) will add credibility to your speech especially if you are doing a persuasive speech. Learning more about various subjects helps me to be able to relate to almost anyone. I can appreciate what they are talking about since I am familiar with their conversation. Researching is a skill that is required in speech, which helps me be more open-minded and knowledgeable. As I am Fundamentals of Speech 4 can relate to others better, they will open up and can relate to me more for they know that I am interested in what they are saying. Academically and professionally, I will also do well since I will know my roles/job better. If I have a problem, I can research it and if I still cannot find the answers, I am able to communicate my issues more effectively. If there is a conflict, I can work my way through it by delivering my point of view better without stuttering, showing anger, confusion, etc. This will build up my self esteem and I will feel more secure and it will

The upper and even middle class Essay Example for Free

The upper and even middle class Essay Ever since the beginning of civilization, there has been a difference in economic and social, creating two separate classes. The wealthier and educated made up the upper status of society making up what is today called upper class. The poor and uneducated made up the people which were often looked down upon by the upper class, and now make up what is considered lower class. This was true in the earliest times of the bible, through the Renaissance time period and even to today. It is nearly impossible for the lower class to become higher class, much less middle class, without being provided a full education by the higher classes. Why can these people of lower class never achieve crossing the class boundary? Most of lower class does not have an education. Therefore their opportunities for having profitable and non-dead-end jobs are nearly impossible by all standards. Because of their lower education, their job selection is limited to mostly manual labor, where pay is minimal, at best. Due to their low-paying salaries, a good college education is usually completely out of the question for their children. College is too much money and they got along fine without a college education, which is sometimes the case, but severely limits future opportunities for their children. Lower class is a vicious cycle. These people represent the people in the cave which can only see the shadows of what is happening around them. They are never allowed out to see the light of a true education, and have to remain in the dark all of their lives. The upper and even middle class, which usually has a good education, have the duty to show the lower class the light and to get these people out of the shadows for good. This can and is being done minutely to help the uneducated by providing scholarships, but for the most part no one is doing anything to help the less fortunate. Unfortunately, today has a very everyone for themselves attitude. Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for life. We need to be concerned for their future, if no one else is, because their future depends solely on their education. We need to make it our goal as a society to educate the uneducated. If everyone is educated then there is equal opportunity and pay therefore eliminating social class. If the enlightened educated class can just come into the cave, relate with the people, and then actually show them the light, rather than telling them what to do, we can actually make a positive difference and make the lives of a lower class citizen much easier. The easiest solution to this problem is to create a utopian society, but those are bound to fail before even being attempted. A utopian society would completely obliterate the class system, because everyone would receive equal pay and equal education, or at least opportunity for education. The best suggestion that is plausible and possible is to create countless scholarships. It would be just like the armed forces; education is free but a certain amount of service is demanded in return. Even though everyone does not have money, everyone has time. All education can be provided by the state and the jobs, needed by the state, can be filled by the graduated students. This can potentially give an education to everyone and keep the jobs needed. It is a win-win situation. If someone could just show society and our leaders the light.

How Do Abiotic Factors Influence the Rate of Photosynthesis?

How Do Abiotic Factors Influence the Rate of Photosynthesis? Table of Contents (Jump to) I. Background Research Design II. Research Question III. Hypothesis IV. Variables V. Apparatus VI. Safety Aspects/Animal Welfare Issues VII. Method Data Collection and Processing Conclusion and Evaluation Evaluation Conclusion Bibliography I. Background Research Photosynthesis is the process in which green plants, algae and cyanobacteria use the energy of sunlight to form carbohydrates from carbon dioxide and water in the presence of chlorophyll. Organisms need complex carbon compounds to build the structure of their cells and to process essential and vital procedures. Some organisms are able to form all the carbon compounds they need using only light energy and simple inorganic substances such as carbon dioxide and water (Alott Mindorff). Photosynthesis can be described by a chemical equation. The overall balanced equation is: Plant cells use carbon dioxide and water for photosynthesis. To finish this process, plants also need light energy captured from the sun, which they gain using a separate process. The usable end product the plant produces through photosynthesis is glucose, which the plant uses as food. The oxygen produced as an outcome of this process is a byproduct and is consequently released back into the environment. Animals and plants both construct fats and proteins from carbohydrates; therefore glucose is an essential energy foundation for all living organisms. The oxygen released as a photosynthetic byproduct provides most of the atmospheric oxygen essential to respiration in plants and animals, and animals in turn produce carbon dioxide vital to plants (Lagassà ©). The rate of photosynthesis in a plant can be determined by three external factors: temperature, light intensity, and available carbon dioxide concentration. In any given situation any one of these may become a limiting factor if they are below the optimal level (Alott and Mindorff). According to the concept of limiting factors, under any combination of light intensity, temperature and carbon dioxide concentration, only one of the factors is essentially limiting the rate of photosynthesis. This is the factor that is farthest from its optimum. As the limiting factor is moved closer to its optimum, while keeping the other factors constant, a point will be reached where this factor is not the one that is furthest from the optimum anymore and another starts acting as the limiting factor. An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor. Increasing carbon dioxide concentration causes a rapid, significant increase in the rate of photosynthesis, which eventually plateaus when the optimal level is reached. E. canadensis is a submerse macrophyte, an aquatic plant immersed in water. It has bright green, translucent and oblong leaves which are borne in whorls of three round the stem (Rose and Reilly) (see fig. 1). It is easily available in aquarium shops or pet shops that have aquarium sections. Fig. 1: Elodia canadensis (Fischer). Design II. Research Question How do different concentrations of carbon dioxide (CO2) solution affect the rate of photosynthesis in Elodea canadensis? III. Hypothesis As the concentration of carbon dioxide increases, the rate of photosynthesis will increase until a certain point where it reaches the optimal level and plateaus. IV. Variables Table 1: Dependent Variable Dependent Variable Photosynthesis rate Table 2: Independent Variable Table 3: Controlled Variables V. Apparatus 25 samples of E. canadensis 500 ml of pre prepared dilute sodium carbonate solutions with the following CO2 concentrations: 1% 2.5% 3% 5% 10% 50 test tubes (used as containers to make a respirometer, not for measurements) 25 x 100 ml 25 x 150 ml 5 x 300 ml beaker (used as containers, not for measurements) 30 cm ruler ) Compact fluorescent lamp as light source 100 ml graduated cylinder ( ± 0.5 ml) Stopwatch ( ± 0.01s) Scalpels Thermometer ( ± 0.01C) VI. Safety Aspects/Animal Welfare IssuesScalpels are sharp and should be used with caution. The glassware involved in the experimentation may lead to injuries if used without caution and broken. Use of liquids may also lead to some risks if spilled because the floor may become slippery. The lab did not lead to any animal welfare issues.VII. Method Label the five beakers with the following: 1% CO2 2.5% CO2 3% CO2 5% CO2 10% CO2 Set up the light source. Place the beakers in a spot that is 20 cm away from the light source. Place one E. canadensis sample into a 100 ml test tube and fill the test tube with 100 ml of the 1% CO2 dilute sodium carbonate solution. The tube should be filled as full as possible. Carefully invert a larger tube and place it over the smaller tube containing the sample plant and the 1% CO2 dilute sodium carbonate solution.   Push the smaller tube all the way into the larger tube using your finger or a pencil and then invert both tubes so that the opening of the larger tube is up. Be sure that the small tube is pushed to the top of the larger tube before inverting it (see fig. 2).   Mark the water level on the test tube with a marker. Place this set up in the beaker which was previously labeled as 1% CO2. As soon as the set up is ready place it under the light source and start the stopwatch. With time, the distance between the water level and the top of the test tube will increase because of photosynthetic activity, which will produce O2 gas. Photosynthetic activity by E. canadensis samples will cause the water to displace and increase the space at the top of the test tube. The volume of fluid displaced will equal the volume of the gas produced. Run the trial for and monitor it for 20 minutes. After every 2 minutes, check the test tube and measure how much of the dilute sodium carbonate solution has displaced with a ruler. Each time after taking measurements, use a marker to mark the new liquid level for the future measurements you will make. Repeat steps 5 to 14 for 4 more times. At the end of this, there should be 5 trials done in total for the 1% CO2 dilute sodium carbonate concentration. Repeat steps 5 to 15 for the remaining 2.5%, 3%, 5% and 10% CO2 dilute sodium carbonate solutions. The process described in the previous steps should give 10 raw data points for each trial with a total of 250 data points. Record this data in a â€Å"Raw Data† table. All the lab work is completed for this experimentation. The lab and the apparatus can be cleaned if necessary.   Data Collection and ProcessingFigure 3: Raw Data for Liquid Displacement over Time in Different CO2 ConcentrationsFigure 4: Processed Data with Means, Standard Deviations and Average RatesFigure 5: Processed Data: Average Photosynthesis Rate in Different CO2 ConcentrationsConclusion and EvaluationEvaluationThe collection of data was an easy process. My results match my predictions. But the uncertainties in the data, which I sh.ould have considered before processing the experiment, are preventing me from making clear and strong statements. One uncertainty preventing me from making clear statements derived from this lab is the fact that I ran the trials for 20 minutes only. It was unfortunately not possible to see any changes in such a short time with low concentrations such as 1% CO2 . If I had run the experiments for longer, I could have seen the photosynthesis rate reaching it’s limit and becoming constant, but because I ran it for a short time, I am not able to understand if , for example 0,3 mm/minutes is the maximum photosynthesis rate the plant Elodea can reach in 10% CO2 concentration. I needed to do it for a longer time to say it has reached a limit or not.Second thing I should have considered is the fact that although they belong to the same species, the plants used in the experiment were still not the same in terms of leaf sizes. If I could use the exact same plant in each tube (take Elodea from one tube and place it in other), results might have changed because plants might be doing photosynthesis at different rates. This is also something I should have searched before starting the experiment, while doing my background research so that I could be sure about it.If I was doing the same experiment again, I would avoid these uncertainties and that would help me make clear statements about my results saying that they match every prediction I made and are strong justifications. Right now, they still match some of my predictions. For example, the photo synthesis rate in 10% CO2 was 0.3 mm/minute while it was 0.2 mm/minute in 5% CO2. This shows that the rate of photosynthesis is greater when higher concentrations of CO2 are present. But like I have stated above, this can be caused by other factors such as the difference in plants or anything I have not considered. Therefore, I should have run more trials.ConclusionMy aim was to see the effects of CO2 concentration on photosynthesis and although I was not able to see them, I was able to make predictions about the effects. I have listed everything that has caused uncertainties in the experiment, and these uncertainties are unfortunately preventing me from making clear statements. If I could do this again, I would avoid all of these uncertainties. The results meet my predictions but one should not say that these results are clear and direct justifications of the background research. Some other factors were involved in the experiment, therefore I would not consider this experiment as s uccessful, and I would do it again.BibliographyAlott, Andrew and David Mindorff.

superman for president Essay -- essays research papers

When we think of the office of President, what kind of person comes to mind? Does he have to be wise and make good decisions? Does he have to look good in a suit? Maybe he should just be a person that you trust in to keep The United States of America running smooth. Well if that is what you think of when you think of the President, my candidate is all of that plus much more. Superman would be the perfect commander in chief of these United States. The first of my candidates multiple qualities is respect for the people. Past presidents didn’t have that characteristic. He realizes that the people come first, that is the whole purpose of becoming the president. Serving the citizen would be his number one priority. When he was working for a newspaper company, he used to secretly go out and save people’s lives, putting his own life in danger. Rescuing old ladies from burning buildings, helping the police bring down some of the toughest villains, he even will get a cat stuck in a tree to come down. The second of my client’s endless amount of outstanding qualities is his ability to make quick and precise decisions. We need a president that will not crack under the pressure of making an important choice for this country. The September 11th incident would be the perfect example. There is a better way to handle this than just bombing everywhere. If Superman were president the planes would have been stopped in their tracks and placed safely on the ground. The economy is another area t...

Comparing Henrik Ibsens Enemy of the People and Kurt Vonneguts Slaugh

Science, Technology and Human Values in Henrik Ibsen's Enemy of the People and Kurt Vonnegut's Slaughterhouse-Five Every day I use technology and science, from the allergy pill I take to my cell phone and my Apple watch, technology is a vital part of my day. Are the human values of integrity, honesty and kindness a part of my everyday life, though? Everyone wants to believe they are a good person, but there are so many things in life that aren't good or positive at all, it is apparent that people-who want to think they are good-do mean things. Some of the worst things are done with some of the best intentions, with the idea that the ends justify the means. Science can improve several things, like one's life expectancy, but can it improve the quality of life? Science without morals to support it can be a dangerous thing. This is seen in several of the works we have read this semester, including Henrik Ibsen's Enemy of the People and Kurt Vonnegut's Slaughterhouse-Five. In Enemy of the People, we see that science and technology are at the mercy of those who hold power, in this case, political power. Dr. Stockmann has discovered, through the use of science, that there is a problem with the economic center of the town-the baths. It is not Dr. Stockmann's use of science that questions the compatibility of science and human values, but his bother, Peter Stockmann's use of technology. Peter is able to control the newspaper, and therefore popular opinion, away from Dr. Stockmann (Act 3). The newspaper is a form of technology that allows news of many events to reach the common person. However, this holds a lot of responsibility with it. Whoever is in charge of what goes in the paper has the ability to shape public opi... ... difficult to include morals in decision-making. It is so much simpler not to think of the consequences of one's actions. However, if everyone were to do this, society would quickly disband. People need to start thinking of their actions as having consequences that affect more than just themselves, and that they must keep this in mind when making decisions. Critical thinking is difficult, and it's not the most pleasant thing, but as Plato has Socrates say in the Apology, "The unexamined life is not worth living" (West & West, 92). Unless we incorporate human values into science and technology, we will be living a life not worth living. Works Cited Lippmann, Walter. The Public Philosophy.

Identifying the Aspects of My Self-Picture Essay

Identifying The Aspects Of My Self-Picture Rachelle Spahr RX1020 Pharmacy Technician August 15, 2013 Professor Broome Identifying the Aspects of My Self-Picture Identifying the aspects of my self-picture that are not working for me wasn’t hard to  accomplish. The things that do work for me on the other hand, are a little more difficult toidentify. I am however, learning how to diminish the negative thinking, to make room for the  positive. Negativity plays havoc on your mindset. I would think things like; I am not smart enough to succeed in furthering my education and I will never amount to anything. Once I failed at something I’d stop trying, believing I can’t fail if I don’t try. Thoughts like these were crippling, keeping me from bettering myself. I have learned quite a bit from reading the Think Build Live Success books. Using the techniques; Challenging negative judgments and replacing destructive judgments, I feel I now have the power to change this self-destructive pattern. I have a lot of past failures and disappointments to learn from. Instead of destructive thinking when I do fail, I will think about what didn’t work and how I can change it for a  successful outcome the next time. In life you have to be open to change, the world changes all the time. Making adjustments in my thinking, will give me the power to make my life how I want it. My failures will strengthen me, but I will no longer allow negative thoughts play their caustic role in my life.
