Kubiak Faculty of Mechanic Engineering and Aeronautics, Rzeszow UniÕersity of Technology, 35-959 Rzeszow, ul. W. Pola 2, Poland ´ ´ Received 9 August 1999; received in revised form 17 February 2000; accepted 17 February 2000 Abstract The main objective of this paper is to study and experimentally quantify the cam and follower wear mechanisms of a diesel direct valve-gear. Camshafts are made of nodular cast iron, surface hardened, ion nitrided and nitrosulphurized, and those made of grey chilled cast iron are mated with followers made of chilled grey cast iron and hardened steel. The investigation was carried out on a laboratory bench equipped with an engine head with a camshaft, followers and systems creating the conditions necessary for a routine run of the valve gear. Cam wear was defined by comparing the profile lifts of the cams. The height of the followers was measured using a coordinative measuring machine and a perpendicular optimeter. The rotational speed, valve displacement and the torque required by the valve gear were measured. Camshaft C9 and the thimble shaped followers with regulating plates F6 were also examined in a diesel engine. The effects of the materials the kinematic pair was made of, heat treatment and thermochemical treatment, the cams’ own stresses at the moment-of-friction value...

...Academic essay on Annie Proulx's "Job Story" Choices are something we all make. Not necessarily important choices, but there will always be a time to make them. It's not always good choices, but they have to be made. There will always be consequences, whether it's bad or good. Throughout the story, Leeland Lee has to make a lot of choices. Where to live, where to work and when to work. All the different choices he made, put him in the position he is now. Leeland Lee is an awkward-looking young boy. His face is heavily boned, which he has gotten from his mom, his neck is quite thick and he has red-gold hair. His eyes are as pouchy as a middle-aged alcoholic. His nose is broad and lays close to his face. Lori Bovee is Leeland Lee's wife. She has an undistinguished oval face, and hair of medium length. Leeland Lee is the protagonist of the story, because he is the main character. I would say Leeland is a flat and static character as he is an endless optimist. He doesn't give up when it comes to finding a new job, and despite his wife dying he still gets a job at Unique Eats. The reason he is a static character is because he doesn't change at all. After getting several different jobs he doesn't change anything, after his mom and wife dies he doesn't change one single thing except the fact he isn't listening to the radio anymore, but since that have been an important factor of the story all along, it can also show a lot about how he has changed. The story starts November...

In the short story we follow Leeland through his harsh life, with ups and downs, in the form of thoughts, feelings, incidents, etc. Leeland is born in a ranch in Wyoming, and lives there with his wife Lori. Leeland does not look particularly good, in fact he is a very unattractive man; (page 91, line 12)“Leeland’s face shows heavy bones from his mother’s side. His neck is thick and his red-gold hair plastered down in bangs. Even as a child his eyes are as pouchy as those of a middle-age alcoholic, the brows rod-straight above wandering out-of-line eyes. His nose lies broad and close to his face, his mouth seems to have been cut with a single chisel blow into easy flesh” And in the top of that, we see how Leeland through his life, tries to find a successful career, but fails consistently. He moves various times from place to place, too seek occupation and good business. But it is hard when you’re a high school dropout, without a career.

...An essay is a piece of writing which is often written from an author's personal[->0] point of view[->1]. Essays can consist of a number of elements, including: literary criticism[->2], political manifestos[->3], learned arguments[->4], observations of daily life, recollections, and reflections of the author. The definition of an essay is vague, overlapping with those of an article[->5] and a short story[->6]. Almost all modern essays are written in prose[->7], but works in verse[->8] have been dubbed essays (e.g. Alexander Pope[->9]'s An Essay on Criticism[->10] and An Essay on Man[->11]). While brevity usually defines an essay, voluminous works like John Locke[->12]'s An Essay Concerning Human Understanding[->13] and Thomas Malthus[->14]'s An Essay on the Principle of Population[->15] are counterexamples. In some countries (e.g., the United States and Canada), essays have become a major part of formal education[->16]. Secondary students are taught structured essay formats to improve their writing skills, and admission essays[->17] are often used by universities[->18] in selecting applicants and, in the humanities and social sciences, as a way of assessing the performance of students during final exams. The concept of an "essay" has been extended to other mediums beyond writing. A film essay is a movie that often incorporates documentary film making styles and which focuses more on the evolution of a theme or an idea. A photographic essay[->19] is an attempt to cover a topic...

...We all know love. We have all loved in some kind of way. We love our parents, significant others and even our friends. But we can also love other things like animals or material things. But what is the difference between loving and liking? And is it better not to love and feel pain or to love and be hurt in the progress? Jonathan Franzen seeks to answer these questions in his essay “Liking Is for Cowards. Go for What Hurts”. The essay “Liking Is for Cowards. Go for What Hurts” is, as mentioned, written by Jonathan Franzen and published in The New York Times, May 28, 2011. Jonathan Franzen is born in 1959, and he is an acclaimed American novelist and essayist. The essay is based on the commencement speech he delivered at Kenyon College in Ohio, USA. “Our technology has become extremely adept in creating products that correspond to our fantasy ideal of an erotic relationship, in which the beloved object asks for nothing and gives everything, instantly. (…)” As Franzen claims in his essay, many people can feel like they love their technological object. It gives them a satisfaction, which human interaction maybe wouldn’t. Franzen however thinks, that people in general don’t love material things: they like them. There is a major difference between loving and liking – even though it might appear small. “Liking, in general, is commercial culture’s substitute for loving.” Products are made to be likeable, but if that concept in transferred to a person, you would instantly see...

...Reaction – “Salvation” The nonfiction short essay “Salvation” written by Langston Hughes in 1940, presents a theme on the literal and often manipulated perception of children. Hughes narrates the essay as he recounts his disappointing attempt at salvation. Hughes aunt told him that when she was saved by Jesus she saw a light, and felt something happen within herself. As children will do, Hughes took her story literally and was heartbroken as he sat in front of the church and watched other children “saved” while he was not. He believed that Jesus must not want him because he did not see or feel anything. In the end, Hughes is forced to lie about accepting Jesus and in turn rejects the Christian faith all together. I related to Hughes story on many accounts. I am a mother of three young children who perceive everything in life literally, and as a young girl I was raised in a very religious environment. I could visualize and almost feel Hughes devastation as he sat at the front of the church crushed by the thoughts of God not wanting him. “Still I kept waiting to see Jesus” (Barnet, Cain, & Burto, 2011, pp. 351). One of the churches that my family attended for a short time during my childhood practiced speaking in tongs. I specifically remember feeling just like Hughes during a service when other children were speaking in unnatural languages perceived to be sent from God himself. I could not understand why I was not chosen to talk for God and intern was hurt and...

...Dog Food Fried, Flipped and Devoured Eating dog food may not be seen as the easiest thing to stomach because the smell, texture and by-products found within the mixture are thought of as awful and revolting. In Ann Hodgman’s “No Wonder They Call Me a Bitch”, although the title may suggest otherwise, different types of dog food are discussed. In this essay, Hodgman aims to inform her readers about the inequality in different types of dog food, as well as to entertain and amuse. Hodgman is writing to a broad audience, one of dog lovers and owners, as well as those that may be curious as to what is really in dog food, or more generally the packaging and processing of mass-produced food of any kind. Language, description and humor are techniques Hodgman skillfully uses to create a strong, convincing essay. Within this essay, Hodgman continually uses diction and syntax that a diverse audience can understand and relate to. In the beginning, the reader feels repulsed by what is written. However, through a light tone of voice and sentence structure, the levity of the experiences and feelings occurring throughout the experiment is conveyed. The personal anecdotes and thoughts make the tone feel less formal and much more story-like. In this way, Hodgman produces a piece that connects the information and readers Shortly after capturing interest through stating questions, Hodgman begins using large amounts of description. Each type of dog food is explained and illustrated so well that...

...Essay films are arguably the most innovative and popular forms of filmmaking since the 1990s”, Timothy Corrigan claims in his diligent new study, The Essay Film. Corrigan may have an agenda to press, and a thesis to justify, but the recent critical and commercial success of the genre is hard to ignore. A cinematic wave that arguably has its contemporary roots in the late 1980s, when American filmmakers such as Michael Moore and Errol Morris rose to public prominence, reached an apotheosis with Moore’s hugely popular, though hugely flawed, Fahrenheit 9/11 (2004) and Davis Guggenheim’s information-heavy An Inconvenient Truth (2006), which conjured a compelling piece of screen drama from Al Gore’s Powerpoint presentation. Nowadays, the Award for Best Documentary Feature at the Oscars is one of the most highly coveted. For Corrigan, the essayistic film “describes the many-layered activities of a personal point of view as a public experience”. While this is a perfectly good starting point, the author is so convinced of the elasticity of his subject that he has trouble constraining it under the broader umbrellas of documentary, non-fiction or even fiction. At times it appears that, for Corrigan, all filmmaking is essayistic. Nevertheless, he traces a convincing history of the genre(s) from D. W. Griffith’s prototypical A Corner of Wheat (1909), which contrasts the lives of the agricultural poor with those of their capitalist exploiters, via Dmitri Vertov and Sergei Eisenstein to...
