Carbon and Potassium Argon Dating essays

Carbon and Potassium Argon Dating essays There are two dating techniques I will quickly discuss. The first I will address is carbon dating, the second is Potassium-Argon dating. Carbon is used for the dating of once living material. To begin, there are three principle isotopes of carbon which occur naturally. These are C12, C13 and C14. Of these three, the first two are stable while the third is unstable, or radioactive which means it will slowly decay. The radiocarbon method is based on this decay or the rate of decay of the radioactive or unstable carbon isotope 14 (14C), which is formed in the upper atmosphere through the effect of cosmic ray neutrons upon nitrogen 14. The reaction is: (Where n is a neutron and p is a proton). Now, C14 is rapidly oxidized into 14CO2 which enters the planets animal life through photosynthesis and the animal food chain. C14 will also disperse into the oceans as dissolved carbonate. Since all life is made up of carbon, all life will intake carbon into the organism, in approximately the same natural ratios that C12, C13 and C14 exist in the atmosphere. These ratios remain steady until the organism dies. At which point its metabolism starts and C14 slowly begins to seep out (decay). This decay is what is measured. However radiocarbon dating is only usable for a dating span of about 1,000,000 years ago. Potassium-Argon dating is the only viable technique for dating very old archaelogical materials. This method has been used to date rocks up to 4 billion years old (almost the creation of the earth). Potassium-Argon dating is based on the fact that some of the radioactive isotope of Potassium-40 (K-40), decays to the gas Argon as Argon-40 (Ar-40). By comparing the ratios of K-40 to Ar-40 in a sample of volcanic rock when you know the decay rate of K-40, then date that the rock formed can be determined. This dating technique is possible because when rocks are heated to their melting point, any Ar-40 ...

Learn How To Paraphrase Properly With The Best Online Guide

Learn How To Paraphrase Properly With The Best Online Guide Learning to Paraphrase: A Step-By-Step Guide Paraphrasing is often not taken seriously both by students and teachers, while students think it is the easiest task ever, and teachers, in turn, assume that every student knows well how to do it. There is a good reason for the professors to think so. In our daily speech, each of us paraphrases several times a day, for example, various morning or talk show conversations or phrases, friends, parents, blogs, etc. We all live and communicate. Every day we render something said earlier by one person to another person or party, and we don’t do that word for word. So, paraphrasing is a natural way for all humans to convey information. Thus, if we do it so often, it’s possible to assume everyone knows well how to do it well. However, it’s crucial for students to know how to do it in order to avoid plagiarism. Besides, mastering this skill will allow you citing someone’s ideas without a need of a word for word quotation. When you are able to paraphrase pro perly, you have a chance to make your writing diverse and show how you mastered the material. What Is Paraphrasing? Paraphrasing means to keep the meaning of the original text without copying its exact wording. Massachusetts Institute of Technology defines paraphrasing as taking the words of another source and using your own vocabulary to restate them. A paraphrase is actually swapping the keywords not to parrot the author and render his main idea at the same time. Yes, it may sound really simple, however, there are so many students having troubles with it. The problem is that when paraphrasing, they misinterpret the main idea of the original text. Linguistic scholars define full paraphrase and quasi-paraphrase. According to Bhagat Hovoy, it can cause very subtle but still very essential meaning, implication, and point of view differences. Bhagat Hovoy define paraphrasing as phrases or sentences rendering almost the same meaning through using different words. The Difference Between Paraphrasing and Plagiarism The main difference between paraphrasing and plagiarizing is very simple, correct paraphrasing usually has a source attached or cited. When citing someone else’s source you show that you do not try to produce someone’s work for your own. Ideas are really valuable in academia, so if you try to pass off someone’s idea as your own, it is perceived as stealing. And there is a good reason for that, while some academics spend much time on their studies to come up with those ideas, and stealing them is a serious offense. They might be just phrases or words for you, but those ideas are the result of someone’s hard work. When paraphrasing, you don’t only change the main words but also the sentence structure, and at the same time, you give some new life to the text. According to some experts, if a paraphrase has seven or more words from the original source and it is not acknowledged properly, it is considered to be plagiarism. It is necessary to save the meaning and intent of the original idea as much as possible, but the words and vocabulary, in general, have to be different. It is a sort of following a recipe and at the same time, substituting each ingredient by something else and getting the same dish at the end. And don’t forget to state the original author in the reference. The Difference Between Paraphrasing and Summarizing When summarizing, you can gather all the main ideas of another thinker or author in their core concepts. There is a very small difference between a summarized paragraph and a paraphrased one. A paraphrased paragraph, as a rule, is aimed to give the main idea of what it is referring to. A summarized paragraph is intended to show the main points and ideas of the initial source. Both of them must have citation and references to the original source. It is very possible to make a properly paraphrased summaries and even plagiarized summaries. A summary that is paraphrased properly should restate a written summary via new vocabulary and structure. It also requires correct in-text citation. A plagiarized summary will restate the same original summary’s ideas using many the same keywords. And it is not referred to the original author. How to Paraphrase It requires some skills and practice to paraphrase a point, argument, or idea of another person. The following tips will help you master this skill the soonest. The order of the words and sentence has to be adjusted. Before thinking of new words for your sentence, you should change the whole structure of the sentence. A new sentence should start at a different place than the original one. This way, you will have to make wording changes. For example: The meeting was rescheduled while the deputy had to go to the head office. – The deputy head to go to the head office, so the meeting was rescheduled. So, you just restructure your sentence and can start substituting the words to paraphrase your own sentence. Such restructuring impacts the tone, too, it brings freshness to the original idea. Sometimes paraphrasing allows making the ideas of an academic more understandable and readable, especially if you make the sentence structure easier. When restructuring, you are free to change the length of the sentence. You can make too long sentences shorter, and vice versa, combine few short sentences into a longer one. The writing manner of some academics requires the readers to read the sentence over again in order to understand it, so you can restructure it and make it easier and accessible to your reader. Substitute new words. This step is one of the most crucial to write a proper paraphrase. When using new vocabulary, you show your ability to understand everything that was said by the author and at the same time, choose the synonyms conveying the same meaning. Too complicated and esoteric words can be replaced with easier ones. And vice versa, too generic words can be replaced with those that express the main idea better. If you want to use some set phrases, you can still do it. If you want to refer later to the original turn of the author’s phrase, you can also keep it. If necessary, add the definition of terms. One of the best paraphrasing benefits is the opportunity to improve the original work. If the author didn’t provide any illumination, you can do it. Review the paraphrased sentence and check if you didn’t change the meaning drastically. It is crucial for paraphrasing. Sometimes, it is necessary to simplify the tone of the original expert to show your understanding of the material and ensure that you didn’t just alter the original meaning. Some synonyms may alter the original meaning of the text, so make sure to choose the proper ones. Paraphrase Example Original: â€Å"The world has a great writer in Erich Maria Remarque. He is a craftsman of unquestionably first rank, a man who can bend language to his will. Whether he writes of men or of inanimate nature, his touch is sensitive, firm, and sure.† (The New York Times, 2007). Paraphrased: Erich Maria Remarque is a great writer of the world. He is a first rank mater who is able to make the language obey his will. His touch is always sensitive, confident, and sure, no matter what he writes about. (The New York Times, 2007). How to Cite a Paraphrase MLA Format The MLA format requires to state the name of the author and the number of the page within parenthetical. For example: (Dickens, 25). However, if you mention the name of the author in the paraphrase, you have to use only the page number at the end. For example: According to Dickens, †¦(25). APA Format This format requires you to use the name of the author and the date within a parenthetical. For example: (Dickens, 1843). In case the author is cited within the paraphrase, just state the data at the end. For example: According to Dickens, †¦ (1843). Chicago Format This format requires you to use the footnotes for referring to a citation within the text. It’s necessary to state the full name of the author, the work title, the date of publishing, the year published, and the page numbers. For example: Charles Dickens, A Christmas Carol, (London, 1843), 25. If you refer to the work for the second or more times, then use the abbreviation of the citation For example: Dickens, Christmas, 25. Paraphrasing Tools Fortunately, modern technologies develop fast and make students’ life even easier. Such tools help not only finds variants for their writing but also check it for various spelling and punctuation mistakes.

A+ Essay Example | Topics and Well Written Essays - 750 words

A+ - Essay Example Washington was an indefatigable actor who seemed to have lived the life of Boone himself, having the vitality of a Black man who was trying to fight for his rights and the rights of his fellowmen during the time of the busing system. Will Patton, on the other hand who played the role of Bill Yoast, the White American who coached along with Boone, was quite the opposite. His part seemed boring that if he were given longer parts in the movie, the story would have been a bore. Although he is a good actor himself, Patton’s soft voice and sometimes timid manners can make his parts monotonous. On a general note, the performance of the actor is worthy of an acclamation despite his serious role which probably influenced his mood in the movie. The Titans, the football team coached by the two aforementioned characters, portrayed different personalities, completing an exciting team of young people. Ryan Hurst who played the role of Gerry Bertier, the team’s captain played his role well, as he showed how the player bloomed from a self-centered, bigoted racist to a leader who valued his team’s attitude rather than race and status. His Black counterpart Wood Harris, who played the role of Julius Campbell, gave an equally highly rated performance. He had the same dynamic exuberance as Hurst that they shared together in bringing to life their respective roles. Both actors showed their emotions unrestrainedly, making their performances realistic and moving. The friendship that developed between the two characters was beautifully pictured through the emotions, conversations and naturally executed performances of the actors. Adding to the exciting and smooth flow of the story were the contributions of other actors who played the roles of other football players in the team. The different characterizations first of all, showed the many variations of characters, attitudes, beliefs and perspectives of people, which in real life; make living more beautiful,

Communication at work Essay Example | Topics and Well Written Essays - 2500 words

Communication at work - Essay Example These two cultures are distinct not only in terms of norms and values but also differ with respect to how people behave and interact with each other. In today’s increasingly globalised world people from different cultural backgrounds are required to work together and have consensus on critical issues. Effective communication becomes very important in the context of such working relationships. It is therefore of particular significance to examine the influence of culture on the communication styles adopted by individuals as well its impact on people’s personal relationships. This paper illuminates the ways through which salient cultural characteristics influence an individual or whole society’s communication styles. It categorises the differences in cultures with respect to individualistic and collectivistic approaches as well as high and low context of communication. It basically aims to illustrate that culture plays a very important role in determining the way people communicate and interact with each other. Culture plays an important role in determining the specific traits and characteristics of individuals belonging to a group that are distinct from other groups of people. People tend to identify themselves with respect to cultural groups and take pride in associating with them. Hofstede defines culture as, â€Å"the collective programming of the mind which distinguishes the members of one category of people from another† (51). People in a separate group share similar characteristics that are identifiable with the help of visible traits and qualities. Drake delineates that, â€Å"culture describes a group’s relatively homogenous evaluations of multiple, interrelated phenomena† (320). These homogenous cultural traits develop into certain social norms and values that have a significant impact on how people think, feel, observe

Johann Wolfgang Von Goethe Essay Example for Free

Johann Wolfgang Von Goethe Essay Johann Wolfgang von Goethe was a German writer and polymath back in the 1800s. Goethe is considered the supreme genius of modern German literature. Although he was alive so long ago, the ideas he put out there are still pertinent to the modern world: such as my personal life, recent movies, and current events. Goethe came up with this viewpoint on life: Until one is committed there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiative (and creation) there is one elementary truth, the ignorance of which kills countless ideas and splendid plans that the moment one definitely commits oneself, then providence moves too. All sorts of things occur to help that would never have otherwise occurred. A whole stream of events issues from the decision rising in one’s favor all manner of unforeseen, incidents and meeting and material assistance, which no man could have dreamed would have come his way. Whatever you can do, or dream you can, begin it. Boldness has genius, proven and magic in it. Begin it now! Goethe’s quote is a universal truth. His philosophy is even proven in my life. A project was given to me that I grew abhorrence for. Procrastinating until a couple days before the due date, I became upset and overwhelmed. I started convincing myself I could not do it. My mother said, â€Å"you’re making it harder than what it is. Do your research. Let the ideas come to you. It will all come together once you start. Stop putting it off and just do it. â€Å" With that in mind, I centered my concentration to my project and nothing but my project. Ideas kept coming to me as I let my mind and words flow. I became the person I needed to pretend to be for the project. I completed it to my best ability. I even made the appearance of my project outstanding. My teacher was so impressed with my work that she presented it to the class, and it was passed around the room. It all happened because I focused my mind on that specific goal. The movie Forrest Gump is an all-time favorite. The main character was committed to every task he was given. One day he decided to run, and he ran across the United States. It took him 3 years, 2 months, 14 days and 16 hours until he felt he was finished. Furthermore, while he was at camp in the army, all he did was play ping-pong. All he thought about was ping-pong. He even played ping-pong in his sleep. He was so good a whole crowd would come to watch him play. Even when he was in the army and went to save his â€Å"best good friend† Bubba, he didn’t stop until he found him. He saved his whole platoon that day while searching for Bubba. Every time he was on a mission or had a goal, he would direct all his focus to that particular objective. He had the ability to focus on anything and do it to his full potential. In the world today, we are in an economic crisis. Companies lay off workers; therefore, there are loads of unemployed people. Since they have no jobs, they are not receiving money. Companies aren’t selling much because people have no money to buy things that are not necessities. There is no flow of money. Everyone is afraid to put their cash out there because they are frightened by the fact that they might not be successful and wouldn’t have enough to buy necessities anymore. There is ineffectiveness and hesitancy in the world. No one wants to take a risk and be committed to one thing. Once people devote themselves to fixing the economy, it will happen. However, everyone is waiting on someone else to do it. Just like in the great depression, everyone was afraid to do something about the problem, until everyone said enough is enough and were devoted to fixing the problem; and look what happened because of that. We solved the crisis. In my final analysis, many people are not focused and are worried about too much. Focus on one thing and commit yourself to it. Everything a person does should be there center of attention. By doing this, one will achieve their goal and maybe even more than expected. Goethe’s philosophy shows how to reach a goal: Focus, commit, and do it. Just like Nike, a successful shoe company, says, â€Å"Just do it† and whatever you want to happen, will happen.

Electronic Mail and The Written Word :: Writing Technology Technological Papers

Electronic Mail and The Written Word Imagine a world without cyber culture technology. Picture using telegrams, typewriters, and payphones to connect to the world, sending all correspondence through mail, and leaving messages on home answering machines. At one time, these outdated items were the wave of the future. Mark Twain couldn’t believe his eyes when he saw the typewriter. Why aren’t these technical advances not good enough anymore? Why have these ways of communicating become historical artifacts? Most of one’s answer lies in the fact that people are constantly looking for faster, more convenient ways to achieve their goals, and cyber culture does just that. Tools such as e-mail provide one with a way to write and communicate with others in a very convenient way. The world we live in is very fast paced. Tasks such as hand writing and mailing letters have become too time consuming. As Dennis Baron writes in his essay â€Å"From Pencils to Pixels†, â€Å"†¦the physical effort of handwriting, crossing out, revising, cutting and pasting, in short, the writing practices I had been engaged in regularly since the age of four, now seemed to overwhelm and constrict me, and I longed for the flexibility of digitized text† (Tribble and Trubek 36). Besides the troubles of writing a letter, one would then have to stamp and seal the envelope, and rely on the trusty post office to deliver your letter in a timely manner. As essayist Adam Gopnik states, â€Å"Ten years ago, even the most literate of us wrote maybe half a dozen letters a year† (181). Ten years ago, one would have more than likely picked up the phone rather than sit down and write a letter. E-mail, in a way, has digitized the letter. It has created a way where people can conveniently correspond daily. One can e-mail a friend in California, a professor at Eastern, a grandparent in Florida, and a spouse at work all in a matter of minutes. E-mail, in some cases, is the only way people communicate with each other. For example, I have just recently within the past year come into contact again with my best friend from elementary school. Since she travels frequently to other countries for her job, it would be very difficult to keep in touch with her via letters and phone calls.

Manage Recruitment, Selection & Induction Essay

Question 1: Explain the role of probation as part of the recruitment process. All new staff employees are required to serve a probationary period. The probationary period allows the Department and the employee the opportunity to assess each others suitability. It is the responsibility of the Supervisor to continually review the services of staff on probation. An employee must be consulted if there are any problems with performance. Question 2: Explain the term ‘merit selection’ and its implication on equal employment opportunity. Selection based on merit is where the best possible match is made between qualifications, knowledge, skills, abilities and relevant experience of the applicants, and the selection criteria in the Position Description. When assessing applicants, only selection criteria are taken into account; that is, unlawful discrimination based on other applicant characteristics must not occur. In the case of casual and sessional staff, merit is determined by assessing applicants qualifications, skills, knowledge and experience against the duties to be performed. Question 3: Explain the relevant terms and conditions of employment. Not every code of practice of the employer which is referenced within the contract may have any force, but rather, can be used as a guideline. Therefore, when considering whether or not a specific document imposes contractual obligations, the test to be applied in determining intention, is whether a reasonable person would come to the conclusion that the person making the promise, had the intention of being bound by the statement. Question 4: Explain at least 2 valid psychometric testing that you can use in your selection process.

Work style questionnaires (personality/motivation/Emotional Intelligence) Work style questionnaires or inventories are concerned with how you typically behave, such as?the way you relate to others or the way you approach and solve problems. They generally?explore personality characteristics relevant to the world of work. To answer the questions you often need to think about what you would do in a work situation. If you have no formal work experience, think about how you behave in similar situations such as voluntary work, university activities or when you are participating in your hobbies. Work style questionnaires look at factors such as: Ways of thinking, feeling and acting in different situations Interpersonal style, conflict style, leadership style Patterns of coping with stress Interests – how much do you like carrying out various types of activities at work.

Political View Essay

My first political view was formed through my family. Although politics weren’t really discussed with children, I eavesdropped in the conversations from time to time. I would hear how they liked one candidate over the other due to the issues they stood for. By overhearing my parents, I learned which issues were favored in my community. Those I grew up around were democrats. I heard a lot about needing officials in office that cared about the people instead of money. Learning about government in school growing up allowed those views learned from my parents to be challenged. Although the curriculum was generally unbiased, the teachers that taught my courses had the opportunity to add their own opinions on a mass amount of political issues. This changed my mind on the democratic views that I had. The media has also influenced me through the information I have gained through it. Television and social media often discusses a lot of politics. They continue to cover the daily activities of the government. The presidential election is covered on the news as high priority. I am able to learn about the candidates that are running and each of their views. Because I don’t try to associate myself with a particular political party, the televised debates help me decided who to vote for president. Although my family, teachers, and the media has been a big influence on my political views, my own experiences with politics have formed my views the most. A lot of my life’s experiences have been affected by politics. Issues such as education and employment are big ticket items in politics that I am directly affected by. Keeping up with the current issues allow me to know what’s going to change for me personally. Although I am not tied to any specific political party, I do have certain issues that are important to me.

How to Identify Prepositional Phrases

How to Identify Prepositional Phrases Prepositional phrases are a central part of virtually every sentence spoken or written. Simply put, they always consist of a preposition and an object or objects of the preposition. So its good to get acquainted with this essential part of a sentence and how it affects your writing style. Here is the first paragraph of Chapter 29 of John Steinbecks famous novel The Grapes of Wrath, published in 1939. As you read this paragraph, see if you can identify all the prepositional phrases used by Steinbeck to convey the dramatic return of rain after a long, painful drought. When youre finished, compare your results with the second version of the paragraph, in which prepositional phrases are highlighted in italics. Steinbecks Original Paragraph in The Grapes of Wrath Over the high coast mountains and over the valleys the gray clouds marched in from the ocean. The wind blew fiercely and silently, high in the air, and it swished in the brush, and it roared in the forests. The clouds came in brokenly, in puffs, in folds, in gray crags; and they piled in together and settled low over the west. And then the wind stopped and left the clouds deep and solid. The rain began with gusty showers, pauses and downpours; and then gradually it settled to a single tempo, small drops and a steady beat, rain that was gray to see through, rain that cut midday light to evening. And at first the dry earth sucked the moisture down and blackened. For two days the earth drank the rain, until the earth was full. Then puddles formed, and in the low places little lakes formed in the fields. The muddy lakes rose higher, and the steady rain whipped the shining water. At last the mountains were full, and the hillsides spilled into the streams, built them to freshets, and sent them roaring down the canyons into the valleys. The rain beat on steadily. And the streams and the little rivers edged up to the bank sides and worked at willows and tree roots, bent the willows deep in the current, cut out the roots of cotton-woods and brought down the trees. The muddy water whirled along the bank sides and crept up the banks until at last it spilled over, into the fields, into the orchards, into the cotton patches where the black stems stood. Level fields became lakes, broad and gray, and the rain whipped up the surfaces. Then the water poured over the highways, and cars moved slowly, cutting the water ahead, and leaving a boiling muddy wake behind. The earth whispered under the beat of the rain, and the streams thundered under the churning freshets. When you have completed the identification exercise in the original paragraph, compare your results with this marked version.

The Wright Brothers Make the First Flight

The Wright Brothers Make the First Flight At 10:35 a.m. on December 17, 1903, Orville Wright flew the Flyer for 12 seconds over 120 feet of the ground. This flight, conducted on Kill Devil Hill just outside of Kitty Hawk, North Carolina, was the very first flight by a manned, controlled, heavier-than-air aircraft that flew under its own power. In other words, it was the first flight of an airplane. Who Were the Wright Brothers? Wilbur Wright (1867-1912) and Orville Wright (1871-1948) were brothers who ran both a printing shop and a bicycle shop in Dayton, Ohio. The skills they learned from working on printing presses and bicycles were invaluable in trying to design and build a working airplane. Although the brothers interest in flight had stemmed from a small helicopter toy from their childhood, they didnt begin experimenting with aeronautics until 1899, when Wilbur was 32 and Orville was 28. Wilbur and Orville began by studying aeronautical books, then talked with civil engineers. Next, they built kites. Wing Warping Wilbur and Orville Wright studied the designs and accomplishments of other experimenters but soon realized that no one had yet found a way to control aircraft while in the air. By studiously observing birds in flight, the Wright brothers came up with the concept of wing warping.​ Wing warping allowed the pilot to control the roll of the plane (horizontal movement) by raising or lowering flaps located along the planes wingtips. For instance, by raising up one flap and lowering the other, the plane would then begin to bank (turn). The Wright brothers tested their ideas using kites and then, in 1900, built their first glider. Testing at Kitty Hawk Needing a place that had regular winds, hills, and sand (to provide a soft landing), the Wright brothers selected Kitty Hawk in North Carolina to conduct their tests. Wilbur and Orville Wright took their glider into the Kill Devil Hills, located just south of Kitty Hawk, and flew it. However, the glider did not do as well as they had hoped. In 1901, they built another glider and tested it, but it too did not work well. Realizing that the problem was in the experimental data they had used from others, they decided to conduct their own experiments. To do so, they went back to Dayton, Ohio and built a small wind tunnel. With the information gained from their own experiments in the wind tunnel, Wilbur and Orville built another glider in 1902. This one, when tested, did exactly what the Wrights expected. Wilbur and Orville Wright had successfully solved the problem of control in flight. Next, they needed to build an aircraft that had both control and motorized power. The Wright Brothers Build the Flyer The Wrights needed an engine that would be powerful enough to lift a plane from the ground, but not weigh it down significantly. After contacting a number of engine manufacturers and not finding any engines light enough for their task, the Wrights realized that in order to get an engine with the specifications they needed, they must design and build their own. While the Wilbur and Orville Wright designed the engine, it was the clever and able Charlie Taylor, a machinist who worked with the Wright brothers in their bicycle shop, who built it carefully crafting each individual, unique piece. With little experience working with engines, the three men managed to put together a 4-cylinder, 8 horsepower, gasoline engine that weighed 152 pounds in just six weeks. However, after some testing, the engine block cracked. It took another two months to make a new one, but this time, the engine had a whopping 12 horsepower. Another engineering struggle was determining the shape and size of the propellers. Orville and Wilbur would constantly discuss the intricacies of their engineering problems. Although they hoped to find solutions in nautical engineering books, they ultimately discovered their own answers through trial, error, and lots of discussion. When the engine was completed and the two propellers created, Wilbur and Orville placed these into their newly built, 21-foot long, spruce-and-ash framed Flyer. With the finished product weighing 605 pounds, the Wright brothers hoped that the motor would be strong enough to lift the plane. It was time to test their new, controlled, motorized aircraft. The December 14, 1903 Test Wilbur and Orville Wright traveled to Kitty Hawk in September 1903. Technical difficulties and weather problems delayed the first test until December 14, 1903. Wilbur and Orville flipped a coin to see who would get to make the first test flight and Wilbur won. However, there wasnt enough wind that day, so the Wright brothers took the Flyer up to a hill and flew it. Although it did take flight, it crashed at the end and needed a couple days to repair. Nothing definitive was gained from this flight since the Flyer had taken off from a hill. The First Flight at Kitty Hawk On December 17, 1903, the Flyer was fixed and ready to go. The weather was cold and windy, with winds reported around 20 to 27 miles per hour. The brothers tried to wait until the weather improved but by 10 a.m. it had not, so they decided to try a flight anyway. The two brothers, plus several helpers, set up the 60-foot monorail track that helped keep the Flyer in line for lift-off. Since Wilbur had won the coin toss on December 14,  it was Orvilles turn to pilot. Orville  clambered onto the Flyer, laying flat on his tummy on the middle of the bottom wing. The biplane, which had a 40-foot 4-inch wingspan, was ready to go. At 10:35 a.m. the Flyer started off with Orville as pilot and Wilbur running along the right side, holding onto the lower wing to help stabilize the plane. Around 40 feet along the track, the Flyer took flight, staying in the air for 12 seconds and traveling 120 feet from liftoff. They had done it. They had made the very first flight with a manned, controlled, powered, heavier-than-air aircraft. Three More Flights That Day The men were excited about their triumph but they were not done for the day. They went back inside to warm up by a fire and then went back outside for three more flights. The fourth and final flight proved their best. During that last flight, Wilbur piloted the Flyer for 59 seconds over 852 feet. After the fourth test flight, a strong gust of wind blew the Flyer over, making it tumble and breaking it so severely that it would never be flown again.   After Kitty Hawk Over the next several years, the Wright Brothers would continue perfecting their airplane designs but would suffer a major setback in 1908 when they were involved in the first fatal airplane crash. In this crash, Orville Wright was severely injured but  passenger Lieutenant Thomas Selfridge died. Four years later, having recently returned from a six-month trip to Europe for business, Wilbur Wright became ill with typhoid fever. Wilbur never recovered, passing away on May 30, 1912, at the age of 45. Orville Wright continued to fly for the next six years, making daring stunts and setting speed records, stopping only when aches left over from his 1908 crash would no longer let him fly. Over the next three decades, Orville kept busy continuing scientific research, making public appearances, and battling lawsuits. He lived long enough to witness the historic flights of great aviators such as Charles Lindbergh and Amelia Earhart as well as recognize the  important roles that planes played in World War I and World War II. On January 30, 1948, Orville Wright died at age 77 of a massive heart attack.

Design of one Operation Unit - Essay Example The technology currently accounts for more than 20% of air separations. In cryogenic distillation applied in this design, air is liquefied, and then fractionally distilled, separating the air into its constituents primarily nitrogen, oxygen and argon. This is a complex process that is the most common and efficient method of large scale oxygen production. It is also the most efficient method of storing oxygen. Liquid oxygen storage is six to eight times more efficient than high pressure cylinders. The complexities and cool down requirements highly favour continuously operating production plants; this is not usually the mode of operation for field medical facilities. Liquid oxygen can be stored, but there is a loss rate that is dependent on the size of the container, the amount of liquid oxygen in the container, and the ambient temperature. Liquid oxygen cannot be stored for long term use. It is a simple matter to safely fill high pressure oxygen cylinders using liquid oxygen. Cryogeni c air separation is currently the most efficient and cost-effective technology for producing large quantities of oxygen, nitrogen, and argon as gaseous or liquid products. An air separation unit using a conventional, multi-column cryogenic distillation process produces oxygen from compressed air at high recoveries and purities. Cryogenic technology can also produce high-purity nitrogen as a useful by product stream at relatively low incremental cost. In addition, liquid argon, liquid oxygen, and liquid nitrogen can be added to the product slate for stored product backup or byproduct sales at low incremental capital and power costs. Capacity and product specification The designed system comprises of 3 columns with a length of 1 meter each. Its ID is 3cm. The system is equipped with an automated control system for regulation of each cycle’s time to monitor and record rate of flow, system pressure, and temperatures of the columns. The designed system can be applied to an extensi ve range of absorbents and pressures in facilitating the adsorption process. The targeted optimal rate of flow of oxygen to be produce by the system is 80 lit/min. design specifications are illustrated in the tables below, Capacity table: Theoretical Model Fix layer and dynamic regime adsorption is often characterized by continuous fluid flow phase going via an adsorbent layer within a time variable process (Nexant Inc., 2010). This is theoretically represented in the diagram below: At the process start, free adsorbent layer volume is considered as filled up with a given component A which cannot be absorbed and further, the solid is â€Å"clean†, and does not have any absorbing component B. Other assumptions made are that the gas is ideal; the absorbent layer has constant temperature, the section has constant speed, and that there is an insignificant pressure drop in the layer. This process is represented in a mathematical model which incorporates multiple equations referring to adsorbed component in volume element of height, fluid phase, and solid and the balance equation. These equations are illustrated hereafter, Product stands for mass transfer coefficient per absorbent layer’s unit volume. The first two equations can be simplified using a modified time variable as follows, The equations can be solved simoultaneously with knowledge of limit conditions: At the start, adsorbed component concentration is zero at any point in the adsorption

Property Law as Applied to Rural Retreats Essay

Property Law as Applied to Rural Retreats - Essay Example As the discussion stresses this agreement restricting Rural Retreats’ use of Easy Access constitutes a significant instrument that crucially affects the proper use of the lot, where its abandonment in the part of Rural Retreats will negatively affect the well-being of its purchasers and successors in title. The importance Easy Access holds as a car park for the estate constitutes what Sec. 29 of the Land Title Act of 1994 as crucial to â€Å"ensure that the register is an accurate, comprehensive and useable record of freehold land in the State.† This paper declares that no registrable interest exists for Nohrain in this case, the registrar should have registered details about Easy Access being a car park, which cannot be used for other purposes or sold, without the lot owners’ consent. In order to protect his interests to the parking lot, Nohrain, preferably with the cooperation of the other lot owners in the estate, has two options: he can make an appeal by virtue of the Land Title Act for the registrar to correct the register to Easy Access and include the provisions included in the sale of the lots regarding Easy Access, or Nohrain can lodge a caveat on Easy Access to prevent the property from being sold or modified in its terms of use. Nohrain has rights to the easement because as the agreement between Olga and the Council provides, Olga, together with her family, occupiers of her lot, and successors in title, which includes Nohrain, are included among those who will benefit from the free water supply.
