The Physics Of Continuum Mechanics - 763 Words

In continuum mechanics, a Newtonian Fluids is a fluid that the viscous stress arising from its flow, at every point, are linearly proportional to the local strain rate. The reason we research Newtonian Fluids is that Newtonian fluids are the simplest mathematical models of fluids that account for viscosity. In natural world, there are many common liquids and gases that can be assumed to be Newtonian Fluids. For example, water, alcohol, thin oil, air, and most of pure liquids. Newtonian fluids get the name by Isaac Newton, who is one of the most famous scientists in the world. He is the first person who found the relation between the rate of shear strain and shear stress for such fluids in differential form. Newtonian Fluids can be also called linearly viscous fluid, which has been found to describe adequately the mechanical behavior of many real fluids under a wide range of situations. In order to study Newtonian Fluids, we need to understand the concept of fluids. A liquid is a nearly incompressible fluid that will suit to the its container’s shape. However, its volume always independent of pressure. There are four basic states of matter. They are solid, gas, plasma, and liquid. Besides, Liquid is the only state with a definite volume but no fixed shape. Water is the most common liquid on Earth. Liquid and gas are similar in many ways. Both of them can flow and take the shape of a container. However, most liquids cannot be compressed as others. Also liquids will not toShow MoreRelatedThe Quantum Relativistic Mess899 Words   |  4 Pagesactive theoretical frameworks in particle physics that is used in an attempt to successfully reconcile general relativity and quantum mechanics.

The lightning rod, bifocal glasses, swim fins, glass harmonica, urinary catheter, and Franklin stove. The first political cartoon. Poor Richardrs Almanack. The first U.S. Postmaster General. One of the five drafters of the Declaration of Independence. This vast array of contributions by Benjamin Franklin leaves no wonder as to why his face is on the $100 bill or a namesake to many commercial establishments and schools today. His prevalence in todayrs society serves as a constant reminder of his commitment and service to the American people. Many of us know Benjamin Franklin as one of the most well-rounded and revered men in American history. He was a blacksmith, printer, writer, scientist, inventor, diplomat, politician, Freemason, and founding father of the United States of America. His vast expanse of knowledge stemmed from his intellectual curiosity, some of which came from an internal drive and some from the period of Enlightenment thought. While this inquiry led him into these many fields, none have so highlighted his desire to serve those in his community like his experiments and inventions in science. His selfless demeanor shined as a beacon during a time when 18th-century America was struggling and in need of a leader; it was these inventions of Benjamin Franklinrs that helped secure his role in politics and as the future founding father of America. Don’t waste time! Our writers will create an original "Benjamin Franklin: An American Hero" essay for you Create order Born on January 6, 1706, in Boston, Benjamin Franklin was the eighth child of Josiah Franklin (1657-1745) and Abiah Folger (1667-1752). While his mother was from Nantucket, his father was an immigrant from England, arriving just 23 years earlier. Benjamin grew up in a deeply religious family†he was baptized on the day of his birth. His father even offered young Benjamin as a tithe to God and had him attend Boston Grammar School. However, upon learning of Benrs intellectual curiosity and limit-pushing nature, Josiah decided to withdraw him and have him attend Brownellrs English School. Attending school turned out to be a challenge because the Franklinrs had ten children to take care of, so they had Ben working as an apprentice for his father by the age of 10. Again, he found a growing discontent as a blacksmith and felt a strong urge for the sea. It must be noted here that a portion of Benrs quizzical nature must be attributed to Josiah himself, as he enjoyed having people ov er for dinner at the Franklin household to stimulate his childrenrs minds. Having done so much so, Josiah tried to appease Ben by letting him explore other options. Young Benjamin loved books, and this desire to read and learn translated to printing where he served for nine years as an apprentice to his older brother James at a printing house. Ben liked the mechanical and manual challenges of the job, which required critical and analytical thinking to solve. He also saw how the power of words could transform and broaden oners mind; this later served as an outlet for his writing. Ben even published some works in The New England Courant, a journal of his brotherrs printing company. Through this, he was able to express his wit and satire on topics such as politics, religion, education, womenrs rights, and freedom of speech. One day, however, James was taken to jail on account of offence to the Assembly. From his jail cell, he wrote to Ben (then 17) that he was to take over as editor, which meant having to break Benrs original apprenticeship contract. However, James mentioned another secret one. Feeling bound by this contract, Ben took the oppor tunity to go out and explore. He first went to New York City until he realized that he could not find a job. He then went to Philadelphia and worked at a smaller print shop, slowly working his way up the ranks until he wound up as a pressman and compositor in a major print shop. One day in 1724 he went to London because the company needed him to get supplies, but the owner failed to give him letters of credit, so Ben ended up staying in London for a year and a half. Upon his return in 1726, he worked for a couple of print shops until he started his own (The Pennsylvania Gazette, which the first political cartoon Join, or Die was published) in partnership with Hugh Meredith. As his credibility in the printing world was gaining, so was his image as a public figure. In 1727, he formed the Junto, a club aimed at discussing morality, politics, philosophy, and business. Ben even became the official printer of Pennsylvania in 1730 and bought out his partner. That same year he married Deborah Read (1707-1774) through a common-law marriage. The couple had two children together: a son, Francis (born 1732, died 1736) and a daughter, Sarah (1743-1808). Ben also had an illegitimate child, William Franklin (1731-1818), who would later become the Royal Governor of New Jersey. The same year his first son was born, Ben joined the Freemasons and began his period as an author, writing Poor Richardrs Almanack until 1758. The rewards did not stop coming for Ben Franklin. In 1736, he was appointed as clerk of the Pennsylvania Assembly and a year later was named official postmaster for Philadelphia. His time as a politician was on the rise, but it was his initial interest in science in 1743 that helped jumpstart his lifelong career in service to the American people.

Disaster Management Preparedness, Response, Recovery,...

Hurricane Katrina Case Study On August 29, 2009, Hurricane Katrina struck the United States Gulf Coast. It was a Category 3 Hurricane, according to the Saffir Simpson Scale. Winds gusted to up to 140 miles per hour, and the hurricane was almost 400 miles wide . The storm itself did a tremendous amount of damage, but the storm’s aftermath was cataclysmic. Many claimed that the federal government was slow to meet the needs of the hundreds of thousands of people affected by the storm. This paper will examine the four elements of disaster management – preparedness, response, recovery, and mitigation – as well as an analysis on the data presented. Before we discuss disaster management, it is important to briefly sum up the events of the events that began on August 25, 2005 to fully understand the brevity of the situation. Meteorologists began warning inhabitants of the regions that were hit by Katrina on August 23, 2005. By the 28th, evacuations were under way, that day, the National Weather Service predicted that after the storm hit, â€Å"most of the [Gulf Coast] area will be uninhabitable for weeks†¦perhaps longer.† (Spowart, 2015) New Orleans was particularly vulnerable. More than half of the city was built below sea level, and the levees protecting it were built on porous sand. The poorest parts of the city were completely unprepared for a storm surge.

My So-Called Enemy Short Film Review free essay sample

The world is formed by connections, both positive and negative ones. A relationship is the manner by which at least two ideas, protests, or individuals are associated, or the condition of being associated. Connections come in numerous appearances, for example, family enrollments, fellowships, insinuate connections, on a bigger scale, common undertakings, and some more. Likewise, interests are a tremendous segment to connections; an ordinarily known intrigue as well as debatable subject is religion. Religion has united individuals since the very beginning. One situation, which incorporates a tie amongst religion and relations, is the short film, My So-Called Enemy, which gets in contact with the connection between the Jews and Muslims in Israel and Palestine. In this short film, the connection between six young ladies from restricting nations (Israel and Palestine) is endeavoring to discover peace in their home of warfare. After watching, watchers may make sense of that individuals who are instructed to be each other’s enemies can look past the awful and move toward becoming companions. We will write a custom essay sample on My So-Called Enemy: Short Film Review or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For instance, one of the Palestinian young ladies, Inas cites, When I see the Jewish girls as individuals, I love them and all of them are my friends†¦we talk every day, and we eat together, we dance together, and we see them always together. But when I remember that they are Jews, I have my feelings at the same time†¦because their people killed my father. This shows that we’re taught at a very young age what to think about a group at a young age, yet we can think about them differently when were thinking about them individually. When there’s a Jerusalem explosion that kills seven, a Palestinian Israeli girl, Riyam says, â€Å"I did not go put that bomb there, they are blaming us indirectly, they’re blaming.. cause all they ever do is just victimize themselves.† Showing that she knows that people blame groups indirectly just as they were blaming the Palestinians. Another huge piece from the video is the point at which the six young ladies are in a circle hopping around together, yelling, Sisters! Sisters! Demonstrating the young ladies hopping in delight together showing how they genuinely found their tranquility and satisfaction, now withstanding their political and religious contrasts.

Dreams Essays (253 words) - Dream, Neuroscience, Neurophysiology

Dreams For my independent study topic I researched dreams. There are many different approaches philosophers have taken to explain dreams and what they mean. I will go through a couple of them. Many of you may be asking yourself "why do I dream?", there are several answers to that question. The first in the physiological set. We dream in order to exercise our brains. When you're awake, messages are constantly speeding among all your billions of brain cells to keep you moving and thinking and digesting an so on. So the idea is that when you're asleep, dreams exercise the "pathways" between brains cells. A couple of ideas that might help this make sense are; the first couple of years of your life are the most intense for learning which is also when you have the greatest amount of REM sleep?which means your dreaming a lot. Another thing is your brain waves during REM sleep look about the same as your brain waves while your awake. During other parts of sleep, the brain waves look very different (a lot slower) There is also a psychological set of ideas about why we dream. Since psychology has to do with your thoughts and emotions it has been said dreams are actually about immediate concerns in our lives. In the bible and within a lot of cultures dreams are thought to be prophetic, which means they can predict the future. Sigmund Freud a famous philosopher gave us a lot of ideas on how our minds work and was very interested in interpreting dreams. He thought dreams contained symbols hidden deep within our minds and memories.

Free Essays on Japanese Interiors

Japanese Interiors I have always been intrigued by Japanese interiors, but never knew much about the actual meaning and function of these spaces until enrolling in this class. Not only am I personally interested; I know that many future clients will share the same interest. Therefore, I wanted to study this topic more in depth so I could use this design in client’s homes in the future. When studying these interiors, not only did I get to learn about traditional furniture pieces, table presentation, and use of space, but also the means in which they are used. For example, while learning about ceramic ware, I also got to learn about the tea ceremonies in which they are used. Before this class I had an illusion of Japan. I imagined little Japanese people dressed in their colorful kimonos in their perfect and tidy little rooms in their lovely towns. This of course is only a fantasy. In reality, Japan has to not only deal with the lack of physical space, but just like the Westerners, they deal with the clutter that we see as so necessary. Vacuums, television and stereo equipment make creating a beautiful space challenging. Understanding this, it made me appreciate the way the Japanese find beauty in unexpected places. In my opinion, they have mastered the art of seeing past the unappealing and bringing out the beauty. They seek out the subtleties rather than the obvious and are enchanted by shadows. Their sense of order and their eye for shape, texture and color in affect made me pay more attention to these details in my own environment. In class we learned about â€Å"green houses† and how shoji screens, although literally paper-thin and even somewhat transparent, was a major source of privacy.

Ethics in the hospital setting Essay Example | Topics and Well Written Essays - 750 words

Ethics in the hospital setting - Essay Example Consequently they significantly contribute to the effective healthcare outcome of patients as well as become important part of personal and professional growth of nursing professionals. In the patients’ care, the ethics and ethical dilemmas faced by nursing professionals encompass five nursing ethics: altruism, integrity, autonomy, social justice and human dignity (Fowler, 2008). I have often come across ethical dilemmas within my arena which is orthopaedic department. I have to deal with patients who come directly after hip surgery. Encountering ethical issues test the competencies of nurses in terms of the learning experiences and help them evolve into empathetic and empowered healthcare professionals. The three most commonly found ethical issues in acute care setting are: altruism, autonomy and social justice. These issues influence the healthcare delivery as well as the recovery rate of patients in the acute care setting mainly because these issues are intrinsically linked to the core of nursing that highlights personal care, compassion and positive attitude of nurses that helps inculcate inner strength within patients to cope with illness and empower th em with knowledge to facilitate faster recovery (Robichaux, 2012). Altruism is highly crucial element of nursing that promotes greater sense of commitment towards the welfare of other people. The self-sacrifice of individuals for the benefit of others constitutes integral part of nursing. The nurses often tend to sacrifice their time when the patient requires their help. They are highly devoted to the cause of easing pain and providing an encouraging environment of hope and optimistic attitude to the patients and their family. I have strong sense of responsibility that encourages understanding and cooperation among the colleagues. Most importantly, patients’ needs are always at the priority over personal requirements because their ill health makes them vulnerable and giving
