Catastrophic Cyberattack - Essay Example A cyber attack has been defined as a computer-to-computer attack that undermines the confidentiality, integrity, or availability of a computer or information resident in it (O’Shea, 2003). Cyber attacks involve virus and worm attacks delivered through vulnerable exploit engines, denial-of-service attacks (DoS), web defacements of informational sites, and unauthorized intrusions into systems (Colarik, 2006, p. 84). According to the CSI/FBI 2005 Computer Crime and Security Survey, rate of losses from attacks are: viruses (33%), unauthorized access (24%), theft of proprietary information (24%), DoS (6%), net abuse (5%), laptop theft (3%), and financial fraud (2%) (Colarik, 2006, p. 83). But for a cyber attack to be successful, phases of attack must also be successful. The five phases of cyber attacks are reconnaissance, penetration, identifying and expanding internal capabilities, intruder damages the system, and removal of evidence of penetration or theft (Colarik, 2006, p. 83). Cyber attack penetrates the Supervisory Control and Data Acquisition (SCADA) system of a water supply system and poses detrimental effect over the system. Cyber Attack on a Water Supply System During the late 1990s, medium to large water utilities integrated IT and SCADA system.

Media and Masculinity Essay Example for Free

Media and Masculinity Essay Penelitian ini bertujuan untuk memahami dan mendeskripsikan: (1) Konstruksi maskulinitas pada majalah laki-laki gaya hidup FHM. Tujuan tersebut dilengkapi dengan penjelasan realitas sosial yang melatarbelakangi hadirnya majalah laki-laki FHM (global dan lokal/Indonesia); (2) Konstruksi maskulinitas pembaca terkait dengan maskulinitas FHM. Penelitian ini menggunakan paradigma konstruktivis dengan kajian teoretis pada teori konstruksi sosial atas realitas (termasuk juga teori interaksionisme simbolik, dramaturgi dan semiotika), teori media massa dan konstruksi sosial, audiens dan pengkonstruksian makna, majalah laki-laki, dan teori-teori maskulinitas (jender). Penelitian dilakukan dengan menggunakan pendekatan kualitatif dengan menggunakan sasaran studi majalah FHM, pembaca FHM di kota Solo dan Yogya, reviu media (akses internet) serta buku-buku literatur. Reviu media serta buku-buku literatur tersebut dikaitkan dengan realitas sosial yang melatarbelakangi hadirnya majalah laki-laki gaya hidup secara umum di mana FHM merupakan salah satu diantaranya. Teknik sampling yang digunakan untuk studi majalah dan pembaca adalah purposive sampling. Untuk majalah, dilakukan dengan menggunakan teknik maximum variation terhadap rubrik-rubrik tetap yang menghadirkan maskulinitas yang kontradiktif dengan maskulinitas tradisional. Terbitan yang diperiksa adalah FHM edisi perdana (September 2003) s/d April 06. Hal ini dilakukan agar memperoleh gambaran variasi konstruksi maskulinitas yang secara konsisten disampaikan majalah melalui seluruh terbitannya. Setelah menemukan variasi maskulinitas tersebut peneliti membagi rubrik-rubrik tetap yang dimaksudkan ke dalam area-area maskulinitas yang mewakili mereka. Dalam masing-masing rubrik tetap, tidak  semua artikel yang ada sepanjang terbitan yang diteliti akan diambil. Tapi akan diambil artikel tertentu yang dianggap peneliti memiliki variasi ‘teks’ paling lengkap yang ditujukan untuk dapat membahas maskulinitas tertentu secara lebih komprehensif. Untuk pembaca dilakukan purposive sampling dengan kriteria pembaca yang membeli rutin majalah minimal telah membaca selama setahun serta masih berlangsung sampai dengan saat penelitian berlangsung. Pencarian pembaca ini dilakukan melalui milis fhmindonesia, agen-agen majalah dan informasi yang diperoleh dari teman. Pengumpulan data untuk studi majalah dilakukan dengan menggunakan teknik analisis media yaitu menggunakan analisis wacana yang difokuskan pada jender. Sementara itu pengumpulan data untuk studi pembaca dilakukan dengan menggunakan teknik wawancara mendalam dan pengamatan berperan pasif (observasi). Hasil-hasil penelitian dapat dikemukan sebagai berikut: (1) Studi terhadap majalah dan pembaca menunjukkan bahwa majalah laki-laki FHM menampilkan  progressive masculinity (androgyn). That is the masculinity which developes femininity. Yet this magazine still emphasizes the traditional masculinity. The finding which shows the masculinity proggressivity (androgyn) is: (a) Manly character â€Å"Metrosexual† (body image area); (b) â€Å"The equality pattern in the interpersonal relationship between man and women (interpersonal area); (c) The character â€Å"Emotional Man† (emotional area); (d) The character â€Å"FashionedTechno Masculinity† (intellectual area); (e) The character â€Å"Caring Man† in the sexual relationship affairs (sexual area); (f) The lost of man’s role as a breadwinner/a maker a living (functional area). The magazine presents the man’s image as â€Å"Single Blessedness Forever† owns a chance to wish of pleasure for himself and leads the exciting consumption activities; (g) The masculinity with the character â€Å"Social Butterfly† (pleasure area). (2) The progressive masculinity in the fixed rubric on sexual areas as mentioned above are also considered still emphasizing to the the traditional masculinity values: (a) Constructing manly/masculinity as a gender which is ‘having’ (‘to have’) relationship; (b) Constructing manly as a voyeur (a man obtains the sexual satisfaction from gazing woman’s sexual activities) and the texts of woman as a gazed object by man/male gazing. (3) FHM magazine is born in the middle of the rising of a new gender which is called â€Å"Metrosexual† (women-oriented man) as the influence of the success of global feminist movement. (4) Studies on the readers shows that they objectivate  the magazine’s masculinity. It means that readers accept the magazine progressive masculinity as an objective reality. The objectivation of magazine’s masculinity can not be separated from the individual masculinity experiences which are obtained through the socalization of family’s values, peer group, work surroundings, society dan the other media. This matter explains two issues: the first, the magazine’s masculinity objectivation by the readers are always negosiated by individual experiences. The second, magazine’s masculinities is not a new issues at all for the readers, but it is already observed in the daily life (peer group, work surroundings, general society) and the socialization of the other media, so, refer to that explanations the magazine functions is empahasizing the masculinity. Eventhough the magazine offers the new masculinity or the progressive masculinity at the same time, which looks contradictive against the traditional masculinity (which has been normalized), the interaction between the readers and the magazine is dynamic, a competition between push and pull. The interaction result is there is a push toward and a pulling the readers on masculinity which is offered by the magazine. (5) Studies on the readers also shows that readers objectivy traditional masculinity on sexual areas, which means that: (a) Manly/masculinity as a gender which is ‘having’ (‘to have’) relationship; (b) Manly as a voyeur (a man obtains the sexual satisfaction from gazing woman’s sexual activities) and the texts of woman as a gazed object by man/male gazing. (6) Masculinity is â€Å"a classed masculinity,† the objectivication toward the magazine’s masculinity can not happened absolutely because of the existence of some factors which are obstacles such as: economy, interest, necessity, job and marital status.

  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The Civil War  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the United States, the southern states' economies were mainly based on agriculture, but not any normal kind of agriculture, they were based on the agriculture of slave labor. Slavery was deeply ingrained in the culture, so much that only a war could stop it. This war was a gruesome war, made far worse because of the advent of modern rifles, combined with an ignorance of advanced military tactics and lack of medical knowledge. At the time, the method common method of warfare was to line up on a big field and stand up and then shoot. The time that the war occurred was pre-germ theory, methods of antiseptics were unknown. This made it so that great damage would be inflicted upon a person, but there would be no way to properly heal treat it. This combination of factors made this war a particularly bloody and devastating one.   Ã‚  Ã‚  Ã‚  Ã‚  A main factor of this war was that the social entrenchment of slavery ran particularly deep. The institution of slavery had been in place since the first colonies were established in the Americas. Early in American history, when the Constitution of the United States was drafted, slavery was also part of the institution. The southern states wouldn’t have ratified the Cons if slavery were outlawed. The Constitution of the United States was held to be the most holy of documents regarding law. Yet even these â€Å"high principled people† and â€Å"educated and sophisticated hierarchs† that approved and created the constitution left grievous discrepancies that later cause a terribly bloody war. If they had taken a clear stance on anti-slavery, the southern states would never have joined the Union. They discretely mentioned slavery in three different sections, but never out right say that it is legal, or illegal. It gave people the right to sue agai nst slavery. And that put doubt (whether they should be in the union) and fear into southern slaveholder’s hearts. This fear and suspicion was only deepened by the growing abolitionist movement, and gin. The cotton gin was of particular importance because much more cotton could be processed. That meant that more acreage could be planted and harvested. This created a huge increase in the am... ...vernment of Great Britain to have become destructive of these ends, the declared the colonies ‘are absolved from all allegiance to the British crown.† By that argument they are saying that it has all been done before, look, you yourself did it, so don’t be unjust and let us break away like you did.   Ã‚  Ã‚  Ã‚  Ã‚  The citizens South Carolina were feeling that they had been violated and abused by the breaking of a viable contract. The northern states were trying to take away their inalienable rights, and they would stand for it. President Lincoln tried to make it clear that â€Å"I hold that, in contemplation of universal law and of the constitution of the Union of these States is perpetual.† South Carolina and all of the other southern states simply did not listen. Lincoln tried to talk sense into them, counter arguing their every point but they would not take any middle ground, as they felt they had already tried that. When it came down to fighting, Lincoln had the high moral ground, and not only that, the larger, more advanced, and better equipped armies. Lincoln tried to not push the point but he was forced to attempt to keep the union together by any means necessary.

Causes And Effects Of Air Pollution

When air gets polluted with dust, smoke, motor vehicles, mills and factories etc. is called air pollution. We know that air is an important element of our environment. But it is a matter of great regret that it is being polluted day by day in different reasons. Causes of Air pollution:There are different kinds of reasons of air pollution. The causes of air pollution are described below.1. Using poison in agriculture: In agricultural sectors, farmers often use insecticides, pesticides and fertilizers etc. These get mixed with air and causes air pollution. Besides, Ammonia is a very common by product from agriculture related activities and is one of the most hazardous gases in the atmosphere. âž ¢ Air Pollution-Paragraph2. Burning of Fossil Fuels: Burning of fossil fuels like coal, petroleum and other factory combustibles is one the major causes of air pollution. Smoke emitting from vehicles like buses, trucks, jeeps, cars, trains, airplanes etc. causes air pollution.3. Industrial sm oke: In mills and factories, large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals is emitted that causes air pollution. It is true that mills and factories can be found at every corner of the world that cause a huge amount of harmful gases that are the major causes of air pollution.4. Indoor activities: Different kinds of household activities like cleaning products, washing, painting etc. emit different kinds of toxic chemicals in the air and cause air pollution.Effects of Air pollution: There are different kinds of negative and harmful effects of air pollution. The effects of air pollution are described below.1. Global warming: Air pollution causes global warming in a great scale. With  increased temperatures world wide, increase in sea levels and melting of ice from colder regions and icebergs, displacement and loss of habitat have already signaled an impending disaster if actions for preservation and normalization aren't undertaken soon.2. Causes dise ases: The effects of Air pollution are very harmful for health. It causes different kinds of respiratory diseases like heart attack, Cancer, bronchitis etc. Every year millions of people of all over the world die due to direct or indirect effects of air pollution.3. Acid Rain:Acid raining is another effects of air pollution. Harmful gases like nitrogen oxides and sulfur oxides are released into the atmosphere during the burning of fossil fuels. When it rains, the water droplets combines with these air pollutants, becomes acidic and then falls on the ground in the form of acid rain. Acid rain can cause great damage to human, animals and crops.4. Depletion of Ozone layer:Air pollution depletes Ozone layer. Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays. Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons, hydro chlorofluorocarbons in the atmosphere. As ozone layer will go thin, it w ill emit harmful rays back on earth and can cause skin and eye related problems. UV rays also have the capability to affect crops.5. Harms to the wild life:Air pollution harms the wilderness. Humans and animals face a lot of devastating effects due to air pollution. Toxic chemicals present in the air can force wildlife species to move to new place and change their habitat. The toxic pollutants deposit over the surface of the water and can also affect sea animals.6. Depletion of Ozone layer:Air pollution depletes Ozone layer. Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays.  Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons, hydro chlorofluorocarbons in the atmosphere. As ozone layer will go thin, it will emit harmful rays back on earth and can cause skin and eye related problems. UV rays also have the capability to affect crops.Conclusion:In the long run, it can be said that it is the right time to protect air pollution. To create a better place to live in for the human being and wilderness we have stop air pollution.

Roller Coasters and Their Theory Essays

Roller Coasters and Their Theory Essays Roller Coasters and Their Theory Paper Roller Coasters and Their Theory Paper 2010 NAME: CAROLENA SEEREERAM DINESH TEELUCKSINGH DEVIANN SINGH VINCENT BAHADUR KERLON MOORE INSTRUCTOR: MR. RISHI RAMPERSAD COURSE: ENGINEERING SCIENCE COURSE: ENGINEERING SCIENCE CLASS: COMPUTER ENGINEERING (YEAR 1) INSTRUCTOR: RISHI RAMPERSAD GROUP MEMBERS: CAROLENA SEEREERAM DINESH TEELUCKSINGH DEVIANN SINGH VINCENT BAHADUR KERLON MOORE ABSTRACT A roller coaster is an amusement park ride where passengers sit in a series of wheeled cars that are linked together. The cars move along a pair of rails supported by a wood or steel structure. In operation, the cars are carried up a steep incline by a linked chain. When the cars reach the top of the incline, they roll free of the chain and are propelled downward due to gravity through a series of drops, rises, and turns. Finally the cars are braked to a stop at the starting point, where the passengers get out and new passengers get on. Roller coasters are considered by many to be the most exciting ride in any amusement park. TABLE OF CONTENTS Task Pages Abstract 3 Introduction 5 Objectives Methodology6 Background Information Design of a Roller Coaster 7-13 * Working of a Roller Coaster 14-15 * Energy Transformations 16 Methodology 17 Main Body 18 * Brief History of Roller a Coaster * Types of Roller Coasters Reference and Appendix 19 INTRODUCTION This project is based on the operations and the energy conversions of a roller coaster and it is designed to make an understanding of how a roller coaster works. A roller coaster ride is a thrilling experience which involves a we alth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor, or other mechanical device which exerts a force on the train of cars to lift the train to the top of track. Once the cars are lifted to the top of the track, gravity takes over and the remainder of the ride is an experience in energy transformation. OBJECTIVES The objectives of this project include: 1) Describing the equipment design and operation of Roller Coasters. 2) Investigating the sources of energy and stating whether the energy is harnessed naturally or if it is renewable. 3) Energy conversion and the losses incurred during the conversion process. ) Identifying the environmental impacts of using such energy. Methodology Different data collection methods were used to collect information of the roller coaster. The most used was the use of the internet. A lot of the information was gathered from different sites and was restructured in one’s own words. Also watching videos from the internet (YouTube) was widely used in gathering of the information. Another method was through reading of text books and encyclopedia based on the roller coaster and once again the information was put together in one’s own words. The following steps were taken when researching the topic. First planning was done on how to do the research and who had to do what in the research. Different members had to do different types of research. Some did through the internet and some researched by reading of text books and encyclopedia. The data was then analyze, then the study of the design of the structure of the roller coaster. Implementation of the information and restructure of the information was then carried out by all members of the group. BACKGROUND INFORMATION Design of a Roller Coaster The design of a roller coaster ride is the first and most important part of the manufacturing process. Because each roller coaster is unique, every detail must be designed literally from the ground up. In order to design a roller coaster, designers must consider what kind of riders will use the coaster. If the coaster is designed for small children, the hills and curves will be gentle, and the cars speed will be relatively slow. Families usually want a somewhat faster ride with plenty of turns and moderate forces. Ultimate thrill seekers want extreme heights and speeds. Next, the designers must consider the space available for the coaster, because roller coasters not only take a lot of ground space, but also a lot of air space. Designers look at the general terrain, other surrounding rides, power lines, access roads, lakes, trees, and other obstacles. Some amusement parks have added so many rides that a new roller coaster has to be designed to thread its way through existing rides and walkways. The next objective for the designers is to achieve a unique feel for the coaster. Designers can draw on a number of techniques to provide a memorable ride. The initial incline can be made steeper or the speed of the lift chain can be made slower to heighten the apprehension of the passengers. Once up the incline, the first drop is usually designed to be the steepest, and therefore the fastest and scariest. Other drops can be designed with a brief flattened section in the middle, and are called double dips. Drops with very abrupt transitions to a flat or upturned section are called slammers because they slam the passengers down into their seats. Letting the cars run close to the ground, in what is called a gully coaster, gives the illusion of increased speed. The advent of steel construction for coasters has allowed a number of variations on the basic roller coaster ride. In some modern coasters, the passengers sit suspended below the tracks rather than riding on top of them. In others, the passengers ride standing up rather than sitting down. Most of the actual design and layout of a roller coaster is done on a computer. The height of the first incline must be calculated to give the cars enough energy to propel them all the way through the ride and back to the station. The horizontal and vertical forces that the loaded cars exert on the track must be calculated at every point to ensure that the support structure is adequate. Because each coaster usually incorporates one or more new and untried features, a working prototype of the new features may be built for testing and evaluation. The prototype is erected at the manufacturers facility, and weighted test cars outfitted with instrumentation are propelled through the test section at the desired speed. Based on these tests, the designers may alter their original design before building the final product. When the calculations, design, and testing are complete, a computer-aided drafting (CAD) program is used to prepare detailed drawings for each of the thousands of parts that will be used to build the new coaster. The Manufacturing Process of a Roller Coaster The actual physical construction of a roller coaster may take place in a factory or on the amusement park site depending on the type and size of the coaster. Most steel coasters are built in sections in a factory, then trucked to the site and erected. Most wooden coasters are built piece-by-piece on the site. Here is the typical sequence of operations for manufacturing both modern steel coasters and classic wooden coasters: Preparing the Site: 1) Before the roller coaster can be installed, the area where it is to be located needs to be cleared and prepared. 2)   If there are existing structures, vegetation, or utilities that need to be moved or demolished, this work is done first. If any of the surrounding terrain needs to be filled or excavated, that work is also done at this time. 3) Holes for the support structure foundations are surveyed and drilled or dug. Sturdy wooden forms are then constructed to hold the concrete for each foundation point. In some areas where the soil is very sandy, large wooden piles may be driven into the ground as foundations rather than using poured concrete. If concrete is used, it is brought to the site in mixer trucks and pumped into place by a concrete pump with a long, articulating arm that can reach each foundation form. Connector plates are imbedded into the concrete on top of each foundation to allow attachment of the supports. Erecting the Main Support Structure: 4) When the foundation is in place, work begins on the main support structure. All the parts for steel coasters are made in a factory and shipped to the job site in sections on trucks. In the factory, the pieces for each support are cut and welded into the required shape using fixtures to hold them in the proper orientation to each other. If a complex three-dimensional bend is required, this may be done in a hydraulic tube bender that is controlled by information from the computer. On wooden coasters, the material for the supports is usually shipped to the site as unfinished lumber and the individual pieces are cut and assembled on site. In either case, the lower portions of the main supports are lifted by a crane and are attached to the connector plates protruding from the foundation points. ) Once the lower supports are in place, they may be temporarily braced while the upper sections are lifted into place and connected. This work continues until the main support structure is complete. Installing the Track: 6) With the main support structure in place, the track is installed. On steel coasters, sections of track are fabricated in the factory with the stanchions an d tubular tracks welded to the track supports. After the sections are brought to the site, they are lifted into place, and the track ends are slid together. The sections are then bolted to the main support structure and to each other. On wooden coasters, wood tie beams are installed across the top of the main support structure along the entire length of the ride. Six to eight layers of flat wood boards are installed lengthways on top of the tie beams in two rows to form a laminated base for the rails. The rails themselves are formed from long, flat strips of steel screwed into the wood base. 7) On steel coasters, walkways and handrails are welded in place along the outside of the track to allow maintenance access and emergency evacuation of passengers. On wooden coasters, the portions of the tie beams outside of the track are used as walkways, and handrails are installed. ) The lift chain and anti-rollback mechanisms are installed on the lift hill, and the braking device is installed on the final approach to the station. Fabricating the Cars: 9) The individual cars for the coaster are fabricated in the factory. The sub frame pieces are cut and welded. The bodies are stamped from aluminum or molded in fiberglass, t hen fastened to the sub frame. Seat cushions may be cut from foam, mounted on a base, and covered with upholstery. Running wheels and guide wheels are bolted in place with locking fasteners. Brake fins, anti-rollback dogs, and other safety components are installed. Finishing the Ride: 0) When the main construction is completed, electrical wiring is installed for the lighting, and the entire ride may be painted. The boarding station is constructed, signs are installed, and the landscaping is put in place. Working of a Roller Coaster The roller coasters work on the principle of conversion of potential energy into kinetic energy. The cars attached to the roller coaster do not have self-powered motor. Instead they are pulled by one chained with the other to the first peak of the roller coaster track. On reaching the top of the first peak the kinetic energy with which the cars are pulled becomes the potential energy. With that the cars of the roller coaster system not only slide down but also move up the second peak. This process is repeated in the subsequent peaks and finally the cars are brought to a stop with the application of brake run. A well designed roller coaster will have enough energy to complete the entire course of the track and will come to an end on the application of brake run at the end. Modern roller coasters have launch mechanisms, which starts off the ride with a high amount of acceleration by means of one or series of Linear Induction Motors and Linear synchronous Motors, powered by hydraulic or pneumatic force. Roll back occurs when a launched train does not have enough potential energy to ascend the top of the first peak. Under the roll back the train comes back to the original launching place for re-launch. In the case of continuous circuit roller coasters, when the kinetic energy is not enough for the train to complete the travel after descending from its highest peak point , it moves forward and backward along the track until all the kinetic energy is released. After that it comes to a stop. Energy Transformations in a Roller Coaster A roller coaster ride also illustrates the work and energy relationship. The work done by external forces is capable of changing the total amount of mechanical energy from an initial value to some final value. The amount of work done by the external forces upon the object is equal to the amount of change in the total mechanical energy of the object. The relationship is often stated in the form of the following mathematical equation. KEinitial + PEinitial + Wexternal = KEfinal + PEfinal The left side of the equation includes the total mechanical energy (KEinitial + PEinitial) for the initial state of the object plus the work done on the object by external forces (Wexternal) while the right side of the equation includes the total mechanical energy (KEfinal + PEfinal) for the final state of the object. Once a roller coaster has reached its initial summit and begins its descent through loops, turns and smaller hills, the only forces acting upon the coaster cars are the force of gravity, the normal force and dissipative forces such as air resistance. The force of gravity is an internal force and thus any work done by it does not change the total mechanical energy of the train of cars. The normal force of the track pushing up on the cars is an external force. However, it is at all times directed perpendicular to the motion of the cars and thus is incapable of doing any work upon the train of cars. Finally, the air resistance force is capable of doing work upon the cars and thus draining a small amount of energy from the total mechanical energy which the cars possess. However, due to the complexity of this force and its small contribution to the large quantity of energy possessed by the cars, it is often neglected. By neglecting the influence of air resistance, it can be said that the total mechanical energy of the train of cars is conserved during the ride. That is to say, the total amount of mechanical energy (kinetic plus potential) possessed by the cars is the same throughout the ride. Energy is neither gained nor lost, only transformed from kinetic energy to potential energy and vice versa. Energy Transformations in a Roller Coaster Methodology Different data collection methods were used to collect information of the roller coaster. The most used was the use of the internet. A lot of the information was gathered from different sites and was restructured in one’s own words. Also watching videos from the internet (YouTube) was widely used in gathering of the information. Another method was through reading of text books and encyclopedia based on the roller coaster and once again the information was put together in one’s own words. The following steps were taken when researching the topic. First planning was done on how to do the research and who had to do what in the research. Different members had to do different types of research. Some did through the internet and some researched by reading of text books and encyclopedia. The data was then analyze, then the study of the design of the structure of the roller coaster. Implementation of the information and restructure of the information was then carried out by all members of the group. Main Body Brief History of a Roller Coaster: A roller coaster train going downhill represents merely a complex case as a body is descending an inclined plane. Newtons first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newtons laws can be applied to every ride. These rides range from The Swings to The Hammer. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster ride is in a gravitational field except with the Principle of Equivalence. An important thing to consider is that the carts on a conventional modern day roller coaster are not self-powered. The movement is generated exclusively by gravitational, inertial and centripetal forces. Although the tracks are getting more and more complex and the speed is ever increasing, the basic principles of physics at work are simple and can be easily understood. Still, the actual task of designing a roller coaster itself is by no means simple, which is reflected by the many obstacles that need to be overcome before a coaster becomes operational. Given this contrasting perspective, this paper is going to take a look at these underlying physics principles as well as some engineering methods that are involved. Energy is essentially applied to the carts only as they are pulled up the first hill. This hill is often called the lift hill. Once the coaster reaches the top, the forces applied to it for the remainder of the ride are mainly gravitational and inertial. Therefore, in essence, the fundamental principle behind the coaster’s operation is the ‘conservation of energy,’ which simply states that energy can neither be created nor destroyed. The total energy which is consisted of ‘potential’ and ‘kinetic’ parts, is therefore constant. As the coaster moves up the lift hill, the total energy exerted on the carts is stored in the system as potential energy. This happens since as the height increases, there is a greater chance for the gravity to act on the cart to pull it down. However, it is not desirable to have the carts fall vertically to the ground, and so a good way to think about what is happening here is that the tracks are designed to manipulate this fall. The second physical principle relevant here is Newton’s first law: This states that an object stays in motion (or conversely stays still) if no external forces are applied. The tendency of objects to do this is referred to as ‘inertia’. Based on this principle, as the cart reaches the second hill (after the lift hill), it continues to rise converting kinetic energy to potential energy. However, some of the energy will be lost due to friction which exists between the tracks and the cart wheels as well as that created by carts moving through the air. Therefore, a few extra hills (which are shorter than the lift hill) are put along the path to ‘recharge’ the cart giving it more potential energy to convert back to kinetic energy. The racks are designed in such a way that at the end of the ride, all potential energy is converted to kinetic energy so there is little need for brakes and the carts essentially stop on their own. Components The worlds tallest and fastest roller coaster, the Kingda Ka at Six Flags Great Adventure in New Jersey. At first glance, a roller coaster is something like a passenger train. It consists of a series of connected cars that move on tracks. But unlike a passenger train, a roller coaster has no engine  or power source of its own. For most of the ride, the train is moved by  gravity  and momentum. To build up this momentum, you need to get the train to the top of the first hill (the lift hill) or give it a powerful launch. Chain Lift The traditional lifting mechanism is a long length of chain (or chains) running up the hill under the track. The chain is fastened in a loop, which is wound around a gear at the top of the hill and another one at the bottom of the hill. The gear at the bottom of the hill is turned by a simple  motor. This turns the chain loop so that it continually moves up the hill like a long conveyer belt. The coaster cars grip onto the chain with several  chain dogs, sturdy hinged hooks. When the train rolls to the bottom of the hill, the dogs catches onto the chain links. Once the chain dog is hooked, the chain simply pulls the train to the top of the hill. At the summit, the chain dog is released and the train starts its descent down the hill. Catapult-launch In some newer coaster designs, a catapult launch sets the train in motion. There are several sorts of catapult launches, but they all basically do the same thing. Instead of dragging the train up a hill to build up potential energy, these systems start the train off by building up a good amount of kinetic energy in a short amount of time. One popular catapult system is the linear-induction motor. A linear-induction motor uses  electromagnets  to build two magnetic fields one on the track and one on the bottom of the train that are attracted to each other. The motor moves the magnetic field on the track, pulling the train along behind it at a high rate of speed. The main advantages of this system are its speed, efficiency, durability, precision and controllability. Another popular system uses dozens of rotating wheels to launch the train up the lift hill. The wheels are arranged in two adjacent rows along the track. The wheels grip the bottom (or top) of the train between them, pushing the train forward. The Breaks Like any train, a roller coaster needs a  brake  system so it can stop precisely at the end of the ride or in an emergency. In roller coasters, the brakes arent built into the train itself; theyre built into the track. This system is very simple. A series of clamps is positioned at the end of the track and at a few other braking points. A central computer operates a  hydraulic system  that closes these clamps when the train needs to stop. The clamps close in on vertical metal fins running under the train, and this friction gradually slows the train down. Types of Roller Coasters: There are many different designs for Roller Coasters but the following are the most popular: * Wooden Roller Coaster * Steel Roller Coaster Wooden Roller Coaster – Wooden coasters use massive wooden trestle-style structures to support the track above the ground. Steel plates are used to reinforce critical joints. Steel Roller Coaster – These may use thin, trestle-style structures to support the track, or they may use thick tubular supports. The track is usually formed in sections from a pair of welded round steel tubes held in position by steel stanchions attached to rectangular box girder or thick round tubular track supports. All exposed steel surfaces are painted.

Hydroponic Vegetable production Essays

Hydroponic Vegetable production Essays Hydroponic Vegetable production Essay Hydroponic Vegetable production Essay Hydroponico Vegetable OProduction0 BY CYF Hydroponics has often been thought of as the future of growing, what many people do not realize is that the concept has been around for a very long time and already has been applied to agriculture. Hydroponics is not Just for flowers; in fact with its growing popularity in the past decade hydroponics has begun to be used for commercial vegetable production around the world. It is attracting to farmers because it presents them with a way to grow in areas and times they might not have been able to otherwise. This can mean that soil quality is not a factor and that the armers can have more control over their own microclimate within a greenhouse. Hydroponics suggests that anyone anywhere can grow his or her own high quality produce under limited conditions. Hydroponics is a method of growing plants without soil. It is the fastest growing sector of agriculture, and it could very well dominate food production in the future. Hydroponics id defined as the science of growing or the production of plants in nutrient rich solutions or moist inert material instead of soil. Hydroponics comes from Latin, the word hydro meaning water, and ponos meaning labor, hydroponics s water working. It is important to know that water alone is not enough to support plants growth. Traditionally soil gives plants anchorage for their root systems and supports vertical growth, it is a source of nutrients, fresh organic matter, and has water holding capabilities. Hydroponics must use fertilizers in their ionic form and supply plants with their essential minerals and nutrients through a nutrient solution. Artificial anchorage is used such as stakes or trellising. One benefit is that it is a more sterile environment than the soil. Soil can contain many toxins and pollutants as well s undesirable insect life and disease pathogens. With hydroponics it is likely that a recall, like the one we had a few years back on spinach that became contaminated with e-coli, would be entirely avoided. Farmers growing hydroponic crops and researchers see many benefits to this method. Higher yields are common and a higher yield per square foot is a given because plants can be grown densely and in vertical or upright ways. Produce from a hydroponic greenhouse is often of very high quality because it has not been subject to the stresses brought on by outside weather conditions and does not bear scars of amage cause by outside factors. It is easier to protect crops from pests and supplement the sun and increase production. Universities and research facilities for medicine and even NASA study hydroponic methods and use them for control experiments. Facilities can have a fully controlled indoor environment where they can research different affects by introducing variables, or like NASA study possibilities for one day growing plants in outer space or even on the moon. Hydroponics has been around for a long time but has began to take a strong foothold only in this past decade or so. It is a common misconception that NASA invented hydroponics; this is false. The first record of anything resembling hydroponics is by Sir Francis Bacon back in 1627 in his book Sylva sylvarum printed the year after his death in which he introduces a concept he called water culture. Water culture became a popular research technique. In 1699 John Woodward published his water culture experiments on spearmint in which he made the conclusion that plants grew better in unfiltered water. By the 1800s we knew that the reason for this is that there are essential nutrients that plants require for growth and ome are found in minerals present in unfiltered water. 1859-65 German botanists Julius von Sachs and Wilhelm Knop developed techniques of soil-less cultivation using nutrient solutions. The growth of plants without soil became known as solution culture, which is a technique that we still use today. In 1929, at the University of California in Berkeley, professor William Frederick Gericke began to publicly promote what he first termed aquaculture. Gericke created a stir by growing vine tomatoes twenty-five feet high in his backyard without the use of soil. William Gericke coined he modern day term Hydroponics in 1937 because aquaculture was already used to refer to aquatic organisms. He was reluctant at first to share his secrets and did not publish any details on his experiments until after he retired from UC Berkeley in 1940. During WWII in a place called Wake Island vegetables were grown hydroponically to feed to passengers on Pan American Airlines when they stopped at this refueling station. Wake Island is a rocky atoll; which has no soil on it in which to grow and it would have been too expensive to airlift in fresh vegetables. Disney orld opened an exhibit called The Land Pavilion in 1982 in their famous EPCOT center, which features a variety of hydroponic growing techniques. Nowadays hydroponics is not Just limited to researchers it has become available to the average citizen and is only beginning to be applied to agriculture in a much broader spectrum this past decade. The benefits of greenhouse hydroponic production are many. In controlled environment the farmer can have control over temperature, humidity, water, nutrients, C02 levels, and even light periods. One main benefit is that no soil is equired, that means there is nothing to till and much labor is eliminated from the growing process. Growing can be done regardless of soil quality and composition. A huge benefit is that water can stay in the system and be reused. Even though water is the main carrier of nutrients hydro systems are able to deliver Just the right amount of water and can reduce waste. Water can be re-circulated in the system and water use is typically 50-90% less than that used for soil crops which are subject to leaching and drainage capabilities. Plant roots can drown hydro takes this into ccount by using highly oxygenated water and preventing anaerobic conditions. So has complete control over nutrition and nutrition costs are lower and applications are more effective and efficient. Plants can absorb the nutrients much faster when they are suspended in water instead of clinging to soil particles. Yields are usually higher and of better quality with more stable results. Because hydro can be grown very densely and even vertically on shelves farmers are able to grow a larger number of plants in a much smaller area. Land use is reduced greatly and allows for farms to e closer to urban areas where they have a shorter distance to travel from harvest to local markets and kitchens. Many hydroponic researchers boast that produce harvested is of higher nutritional value and considered fresher because some crops, like lettuce, can be harvested with roots and remain fresh longer. Pests and disease are easier to contain and get rid of in controlled environments and the sterile environment allows for use of Integrated Pests Management programs that focus on biological controls and reduce the use of harmful pesticides. Disadvantages of hydroponic farming can be the loss ofa buffer, soil, any failure n the system , equipment failure, power outage, can lead to very quick death or damage of an entire crop. Pathogens can breed in these high moisture environments and young plants are susceptible to verticillium wilt and can die from dampening-off. In extreme environments water temperatures must be monitored and controlled so that you dont have any freezing or cooking of your roots. It is much easier and less expensive to heat or warm water in the system than to keep it cool. In desert regions enclosed systems are preferred to prevent loss of water through evaporation. The most common disadvantage is the extremely high cost of start-up and equipment. Since hydroponics is a growing technology the USDA and other organizations often have grants available for farmers working in hydroponics. In 2012 Living Water Farms was the recipient of one of the USDAs Value Added Producer Grants which are awarded to sustainable business ideas. Crop choice is taken into consideration because of the costs involved and certain limitation. Commonly lettuce is probably the vegetable most often grown hydroponically because it is quick and easy. Farmers can go from planting to arvesting a lettuce crop in as little as 30-45 days that allows them to get about 10 harvests out in one year. Tomatoes are another huge hydro crop, some of the largest North American Hydroponic farms focus on tomatoes production, from beefsteak, to vine ripe and cherry. Euro Fresh Farms in Arizona harvest approximately 250,000 tomatoes daily in mid summer. Euro Fresh Farms are also certified pesticide residue free and practice land and water conservation, solar panels are integrated into the design of the greenhouses to further reduce energy costs and the companys carbon footprint. After harvest, excess plant material is composted and waste is reduced. Euro Fresh Farms are not organic but they boast a ten plus year history of contamination free produce and claim to be better than organic because they dont use animal fertilizers which can contain food borne illness like e-coli and salmonella. The other crop they grow besides tomatoes are cucumbers. They are certified by the North American Greenhouse Hothouse Vegetable Growers, and dont use any GMOs. Locally Kennys Strawberry Farm is a great place to visit to see hydroponics working to produce fresh strawberries. The Temecula Valley farm has a u-pick hydro ground away from the reach of rodents and soil borne pathogens. They claim to be all natural and have heartier and healthier strawberries which are not picked until they reach ideal ripeness and redness. Their motto is we grow em You pick em where you can have a family outing and pick strawberries without ever getting dirty. Hydroponic farms in general tend to be smaller, because of costs and provide local markets and restaurants. Most are family businesses that practice sustainability and conservation. They produce a variety of vegetables and herbs, even feed for ivestock. Around the world hydroponics are already being used. There are huge hydro-lettuce fields in Japan, Germany, Pakistan, Australia, and places like the Philippines. Countries like Pakistan are reducing their need for imported produce and are actually beginning to export produce themselves. In the past their soil was considered useless for cultivation, but with hydroponics they are a growing success. In Conclusion, hydroponics is indeed a growing industry and I suspect that as our land gets more populated and developed we will see a rise in this industry. It can be sustainable and health conscience. You can grow more in a small area so it is welcoming to smaller property owners and perfect for urban areas. With each technological advance we get more precision out of every crop. REFERENCES All Season Greens I Easily Produce Your Own Low Cost, Highly Nutritious, Living Feed, 365 Days a Year!

Mesozoic Era - the Geologic Time Scale

Mesozoic Era - the Geologic Time Scale Following both the Precambrian Time and the Paleozoic Era on the Geologic Time Scale came the Mesozoic Era. The Mesozoic Era is sometimes called the age of the dinosaurs because dinosaurs were the dominant animals for much of the era. The Permian Extinction After the Permian Extinction wiped out over 95% of ocean-dwelling species and 70% of land species, the new Mesozoic Era began about 250 million years ago. The first period of the era was called the Triassic Period. The first big change was seen in the types of plants that dominated the land. Most of the species of plants that survived the Permian Extinction were plants that had enclosed seeds, like gymnosperms. The Paleozoic Era Since most of the life in the oceans became extinct at the end of the Paleozoic Era, many new species emerged as dominant. New types of corals appeared, along with water-dwelling reptiles. Very few types of fish remained after the mass extinction, but those that did survive flourished. On land, the amphibians and small reptiles like turtles were dominant during the early Triassic Period. By the end of the period, small dinosaurs began to emerge. The Jurassic Period After the end of the Triassic Period, the Jurassic Period began. Most of the marine life in the Jurassic Period stayed the same as it was in the Triassic Period. There were a few more species of fish that appeared, and toward the end of the period, crocodiles came into being. The most diversity occurred in plankton species. Land Animals Land animals during the Jurassic Period had more diversity. Dinosaurs got much bigger and the herbivorous dinosaurs ruled the Earth. At the end of the Jurassic Period, birds evolved from dinosaurs. The climate changed to more tropical weather with a lot of rain and humidity during the Jurassic Period. This allowed land plants to undergo a large evolution. In fact, jungles covered much of the land with many conifers in higher elevations. The Mesozoic Era The last of the periods within the Mesozoic Era was called the Cretaceous Period. The Cretaceous Period saw the rise of flowering plants on land. They were helped along by the newly formed bee species and the warm and tropical climate. Conifers were still really abundant throughout the Cretaceous Period as well. The Cretaceous Period   As for marine animals during the Cretaceous Period, sharks and rays became commonplace. The echinoderms that survived the Permian Extinction, like starfish, also became abundant during the Cretaceous Period. On land, the first small mammals started to appear during the Cretaceous Period. Marsupials evolved first, and then other mammals. More birds evolved, and reptiles got bigger. Dinosaurs were still dominant, and carnivorous dinosaurs were more prevalent. Another Mass Extinction At the end of the Cretaceous Period, and the end of the Mesozoic Era came another mass extinction. This extinction is generally called the K-T Extinction. The K comes from the German abbreviation for Cretaceous, and the T is from the next period on the Geologic Time Scale - the Tertiary Period of the Cenozoic Era. This extinction took out all dinosaurs, except birds, and many other forms of life on Earth. There are different ideas as to why this mass extinction occurred. Most scientists agree it was some sort of catastrophic event that caused this extinction. Various hypotheses include massive volcanic eruptions that shot dust into the air and caused less sunlight to reach the surface of the Earth causing photosynthetic organisms like plants and those who depended on them, to die off slowly. Some others believe a meteor hit causing the dust to block the sunlight. Since plants and animals that ate plants died off, this caused top predators like carnivorous dinosaurs to also perish.

The Luck of Roaring Camp Essay Example | Topics and Well Written Essays - 500 words

The Luck of Roaring Camp - Essay Example (Harte, 1886, p. 1) The story is set in the 1850’s where a band of men living in the foothills of the Sierra Hills were brought together by one common goal of mining gold in the region. However, when the town’s prostitute, Cherokee Sal, died giving birth to a baby boy, all the men in the camp were shaken for birth was an uncommon occurrence in the region. They were all fascinated by the baby and this marked the start of a beautiful metamorphosis, where the men at the camp not only assumed responsibility for the infant but began to make radical changes in their appearance and lifestyle to provide a comfortable home to the boy, who was later christened as Thomas Luck by the townsfolk. This was one time, when the townspeople got their act together and took care of Luck in the best possible way. They wanted to give him â€Å"the best that money could buy† and strangely enough, the infant was loved and nurtured by this uncultured band of men (Harte, 1886, p. 3). The most profound instance of budding paternal affection is depicted, when the new born Luck holds on to Old Kentuck’s finger that thoroughly embarrasses the man, but he is unable to hide the deep surge of emotion and joy that flushes over him and he relates that event to every man in the camp. The men then find ways to bond with each other and even decide to welcome visitors in this otherwise secluded, notorious town. All the men in the camp began taking extra care of their hygiene and there was a marked fall in the number of profanities that spewed out of every mouth. They were truly trying to be the best father figures for young Luck and despite the fact that fate had a different plan for the Townspeople but it sheds great light on human nature on how they can turn from wild men to protective, responsible adults as soon as an infant made its entry into their lives. Kentuck dies saving the

Film and Television Genres Essay Example | Topics and Well Written Essays - 2000 words

Film and Television Genres - Essay Example There are so many different film genres that are present in the media world today, and although some of them certainly have their similarities, they even more so have their differences, and by understanding about both the similarities and differences of each film genre, we will be able to get a much more aware and critical understanding on each and every one. What is even more, by analyzing all the different film genre's we will not only be able to become more knowledgeable on the genres, but on the world of media as a whole as well. By doing this we will be able to come to a much more understanding and knowledgeable viewpoint on the subject matter at hand overall. This is what will be dissertated in the following. There is really a multitude of different film genres that exist, and in film theory specifically, the term 'genre' refers to that of the primary method of film categorization, and it is a term which is basically used in order to allow separation between films, not only in order to make it easier for movie watchers to be able to predetermine the type of film that it is, but as well so that each film can be more specifically and properly identified and criticized. "A 'genre' generally refers to films that share similarities in the narrative elements from which they are constructed" (Wikipedia, 2007). 'Setting', 'mood', and 'format' are all terms which are used in the film genre classification process: the setting is where the film takes place; the emotional charge which is carried on throughout the film is known as the mood, and the format is the way or manner in which the film was actually shot. Each of these three terms is just as important in the next in regards to the process of c lassifying a film's genre, and they must all thus be taken into account in order to properly assess a film's genre. Film genres are considered as being various forms or identifiable types, categories, classifications, or groups of films which have similar or recognizable patterns which associate them as being in a particular subject area. There are film genres, and then there are genres which are considered as being non-film genres. Some of the most popular and well-known film genres would include that of: action, adventure, comedy, crime/gangster, drama, epics/historical, horror, musicals, science fiction, war, and westerns; some of the most popular and well-known non-film genres would include that of: animated films, British films, children's/kids/family films, classic films, cult films, documentary films, serial films, and silent films. The main difference between film genre and non-film genres is that the film genre titles are more specific and more often used, while the non-fil m genre titles are more subtle and for the most part less popular. The more conventional definitions of genre tend to, for the most part, be based on the notion that they are able to properly constitute for particular conventions of content, and this would include issues such as the theme or setting for instance, or any other film genre subjectivity. It is incredibly important to realize that the attempt to define particular genres in terms of necessary and sufficient textual properties is truly very necessary, and that although it is often seen as being theoretically attractive, often times it can be extremely difficult to complete this process,

Marketing Communication Master Assignment Example | Topics and Well Written Essays - 5000 words

Marketing Communication Master - Assignment Example A stable housing market and a stable growth in the industry and economy, usher in a stable requirement for the electrical, both brown and white goods in the market. The over all requirements in the market have been tending towards a growth that is both uniform and stable. Secondly, in UK audio visual products sell the maximum among all European countries. Research indicates that the hi-fi mini and micro systems have replaced the midi stacking systems in the audio visual industry (Geoffrey A Moore, Aug 1996). In addition to this, it also indicates that the future course of work is in the direction of micro systems and people will prefer these. In the audio-visual sector price has been the major consideration for most of the buyer decisions. However, the manufacturers tend to add value by providing additional features. Based on all these market situations, it is congenial to get into micro hi-fi systems and would be compatible with the existing product line of Microsoft's mp3 players. This should add value to the hi-fi systems already in place; will be a micro player and will be compatible with other Microsoft products already in the market. Marketing communication is based on the planning efforts taken in line with Paul Smith's(2003) SOSTAC structure (P R Smith & Jonathan Taylor, June 2004). Many corporations and businesses around the world make use of the SOSTAC structure to plan their marketing approach. In line with this paper, the plan and the approach for the launch will be based on SOSTAC. The SOS of the SOSTAC is conceptual or a visualization while the TAC is the action plan and implementation that would help to reach the SOS. Situational Analysis, Objectives, Strategies, Tactics, Action and then control make up the SOSTAC model of business planning. In line with this model, this paper will also address the situation in which the launch of the product is going to take place, including competitor information, their products and the markets that they are dominating in. Based on the competition information and on the information pertaining to the various requirements in the market, the objectives for the exercise are set. The strategies and tactics to reach these objectives and targets are then worked out, indicating the action plan for the same. This would help in achieving the targets that were originally set. Appropriate design of control is essential in order to ensure that the company meets its targets without fail. In general the steps of the SOSTAC model mean the following: S Situation Where are we now O Objectives Where do we want to go S Strategy How do we get there - Broad view T Tactics What tools do we use to implement the strategy A Action Detailed Action Plan for each tool / tactic C Control How do we track our progress and know when we have reached the goals (Business Services Agency, 2006). Situational Analysis Audio visual industry in UK has gone through major upheavals. However, the market in UK is more oriented towards listening to lots of audio for most part of the day. While Digital Audio Broadcasting is a major attraction for people who tune their radio in, the other is the tendency towards listening to audio replays. 90% of the UK population listens to 23 hours of music. This takes the form of either the radio or the pre-recorded music on CDs or mp3 memory recordings. Microsoft is

Maintenance Management of Engineering Assets Assignment - 1

Maintenance Management of Engineering Assets - Assignment Example Ventilation systems allow for the supply of air into the building and cooling in normally necessary to lower the temperatures The boilers: The boilers normally produce water that is hot and in some instances produce steam to be distributed in the space within which the system operates. This is achieved either by the use of coils or the use of water pipes leading to the radiator of the HVAC system. The chiller: This is the cooling component of the system. It is normally treated with air that is normally blown over the coils carrying the chilled water in the space of operation for cooling to take place through the ventilations. The fault tree analysis (FTA) can be used to analyze the major faults that are likely to occur in the HVAC system. The major faults that are likely to be encountered in the system can either be controller based or mechanical faults. The FTA diagram below analyses these faults. Control faults of the HVAC system occur in the functional components of the system. The faults can be in the form of variations in the thermal conductance of the fluid in the coils, dehumidification faults and non-linearity in the variation of the control system. These faults in the control system can only be solved through maintenance operations of the system. This is a procedure that is used for the evaluation of the various aspects of a functional system so that we are in a position to identify the critical failures that are likely to occur in the system so that we can be able to minimize or eliminate them through correction of designs. The main objective of Failure Modes and Effects Analysis (FMEA) is to make a determination of the parts that have the highest probability of failing in an assembled system (Salsbury, 2003). The process of Failure Modes and Effects Analysis (FMEA) starts with the smallest components of the system and

Monachy of the Middle ages Essay Example | Topics and Well Written Essays - 1500 words

Monachy of the Middle ages - Essay Example At this point leadership followed the Roman standard of having an Emperor, who took power through being named as successor or through overthrowing the previous successor. At the start of the early middle ages, Justinian I (who ruled from 527-565) was able to restore some of the western territories to the empire, however most remained under Germanic control. The Macedonian dynasty rose to power in 867, cementing the influence of what remained of the Roman Empire1. Those in the West were considered to be barbarians, and any advances that they made were scorned or ignored. The Germanic monarchy in the West was formed from the leaders of tribes and this was often known as the Barbaric Monarchy. Unlike in the East, there was no single leader; instead there were multiple kings, each of whom had to follow three functions. These were: to act as a leader at the time of warfare, as a judge during assemblies and as a priest when sacrifice was needed. Unlike the system in Eastern Europe, under G ermanic monarchy, all sons had equal right to rule. This often resulted in co-rulership of the tribes. Under Germanic monarchy, there were three levels, similar to the class system present in the Roman Empire; these were the king, the nobility and the free man2. The Late Middle Ages (c. 1300-1500 CE) were differentiated by a strong advancement in the level of knowledge and cultural attainment that were obtained. In addition, towns were becoming established as self-sustaining entities that were distinct from one another. Social unrest was prevalent with much of the population being lost through plagues and famines. The influence of monarchs and ruling powers over their citizens was substantially decreased as the consequent of the development of state laws3. These laws were designed to ease the growing civil unrest by providing civilians with reassurance, and by the creation of a system that was distinct from the whims and desires of the monarch. Nevertheless, the monarch remained the predominant power within the Late Middle Ages, determining which laws were established and which were not. Consequently, the Late Middle Ages differed from the Early Middle Ages through the development of more consolidated monarchies and increases in the rights of citizens. The creation of state laws allowed for the application of justice that was relevant to the case in question. Part Two: The Role of Religion on Western Civilization Religious activities have had a significant impact on the formation and development of the Western civilization between the years of 1050 and 1690 CE. One source of this influence was the Catholic Church. The Catholic Church was not the only strong religious influence of the Middle Ages, another was Judaism and Christianity in general as well as the Protestant religion. In 1054, an event known as the East-West Schism saw the division of the roman church into two divisions, the Roman Catholic Church and the Orthodox Church. This was the first developme nt of the Catholic Church as its own entity. The Catholic Church exerted powerful influence on the lives of citizens determining many of the ways in which they interacted and what they could and could not do. An example of this is contraception. Contraception was considered immoral under the Catholic religion, and consequently no member was allowed to use any method of birth control. The result was

Maintenance Management of Engineering Assets Assignment - 1

Maintenance Management of Engineering Assets - Assignment Example Ventilation systems allow for the supply of air into the building and cooling in normally necessary to lower the temperatures The boilers: The boilers normally produce water that is hot and in some instances produce steam to be distributed in the space within which the system operates. This is achieved either by the use of coils or the use of water pipes leading to the radiator of the HVAC system. The chiller: This is the cooling component of the system. It is normally treated with air that is normally blown over the coils carrying the chilled water in the space of operation for cooling to take place through the ventilations. The fault tree analysis (FTA) can be used to analyze the major faults that are likely to occur in the HVAC system. The major faults that are likely to be encountered in the system can either be controller based or mechanical faults. The FTA diagram below analyses these faults. Control faults of the HVAC system occur in the functional components of the system. The faults can be in the form of variations in the thermal conductance of the fluid in the coils, dehumidification faults and non-linearity in the variation of the control system. These faults in the control system can only be solved through maintenance operations of the system. This is a procedure that is used for the evaluation of the various aspects of a functional system so that we are in a position to identify the critical failures that are likely to occur in the system so that we can be able to minimize or eliminate them through correction of designs. The main objective of Failure Modes and Effects Analysis (FMEA) is to make a determination of the parts that have the highest probability of failing in an assembled system (Salsbury, 2003). The process of Failure Modes and Effects Analysis (FMEA) starts with the smallest components of the system and

How the Cameras Use Affects the Overall Production Essay

How the Cameras Use Affects the Overall Production - Essay Example Constant camera practice coupled with technical knowledge is key factors in developing the skills needed producing the best picture for media production. It is important that camera operators are highly skilled in operating and controlling the technical devices in a camera and know to focus the lens to obtain the desired shot. They must also know the techniques in taking shots, panning, tilting, zooming, dollying, image framing, and positioning to produce the best pictures. There are different approaches that a camera operator can use in taking shots depending on the type and purpose of a particular media outfit. For a realist, modernist, or formalist aesthetics, differentiation is presented in the skilled application of image depth. Image depth defines spatial continuity. Broad image depth, where there are wide ranges of objects in focus, produced a different perspective from that of a restricted image depth where an object is isolated from the other objects in the scene (Musburger, Kindem 261). Positioning the Camera Camera operators must determine the best position for the desired image. This requires knowledge in framing, distance, and movement. They must identify the objects or actions that must be contained in the camera frame, determine the appropriate distance and angle, and the best placement of the camera in taking a picture. Camera-mounting devices help in controlling camera movement.

Methods for Sustainability in the Chemical Industry

Methods for Sustainability in the Chemical Industry Table of Contents (Jump to) INTRODUCTION WAYS OF MAINTAINING SUSTAINABILITY IN THE CHEMICAL INDUSTRY 1. RENEWABLE AND CLEAN ENERGY 2. CATALYSIS 3. EFFICIENT WASTE MANAGEMENT AND RECYCLE 4. SAFER SOLVENT CONCLUSION REFERENCE INTRODUCTION Also known as green chemistry, sustainability in the chemical industry is the practise or a viewpoint of chemical researches that is design to focus on the reduction or elimination of the chemical processes that results to the production of a generation of hazardous substances particularly to the environment and humanity (USEPA, 2015). With reference to the current climatic changes, physical evidences shows that the rate at which solar energy is received from the sun compared to the rate at which it is lost to space, has severely increased over the previous decades, Hence, negatively affecting the climates of different regions across the globe. This could be correlated to the fact that many chemical processes used in the industries today are not sustainable enough (Blackstone 2015). Figure 1: Gas Emission from a Chemical Plant Source: www.texastribune.org WAYS OF MAINTAINING SUSTAINABILITY IN THE CHEMICAL INDUSTRY There are several approaches to maintain sustainability in the chemical industry today; however this report concentrated on four of them; 1. RENEWABLE AND CLEAN ENERGY Most chemical processes requires energy in order to materialize, and with fossil fuel becoming progressively more scarce with comparison to demand, there is the necessity to find alternative sources, such as recycled or renewable energy. The aftereffects of using fossil fuel, particularly to operate a chemical plant such an ammonia plant for example is that a large amount of Carbon-monoxide is produced as by-product hence contributing to the current global challenges of climate change (University of York, 2014). Ways of Using Energy Effectively By using good insulative materials and well-sustained equipment, heat loss will be reduced during the process of production and any surplus heat should be re-used to produced hot water rather than being lost to the environment. Chemical reactions that require lower temperature should be considered when the option is available. Where possible, chemical plants should avoid using generator to generate electricity because of the emission of carbon-monoxide. 2. CATALYSIS The use of catalysts plays an enormous role in the enhancement of a more sustainable process for the production of chemicals. There are several benefits in using and developing catalysts for industrial chemical reactions, some significant ones being: They positively affect the condition needed for the chemical reaction, often decreasing the energy required by reducing the pressure and temperature. They facilitate the usage of alternative reactions which generally have a better atom economy therefore reduces wastage. They enable the possibility to precisely control the reaction pathways, hence decreasing unwanted by-products and making it easier to purify and separate the preferred products. Example: In the production of nylon-6 (an essential polymer used to make fabrics); cyclohexanone is altered into caprolactam through the means of oxime (reacting hydroxylamine hydrogen-sulphate with ketone). This process requires the need to isomerised sulphuric acid with the reactant (caprolactam) which then gives off ammonium sulphate (wastage). With the introduction of a catalyst (zeolite), the chemical reactions are rearranged hence resulting to elimination of the subsequent wastage from sulphuric acid (University of York, 2014). 3. EFFICIENT WASTE MANAGEMENT AND RECYCLE As much as it is practically impossible to have zero-wastage, chemical practises can imbibe the following culture below; Waste Avoidance: Where possible, chemical processes that involve less or no wastage should be considered simply because it saves time, money and preserves the environment. Generally, chemical waste products are treated specially due to their hazardous tendencies to humanity and the environment (Blackstone 2015). Waste Re-usage: In cases whereby it is almost impossible not to produce waste, alternative means should be devised in order to re-use the waste products created. For example, a chemical plant, that conducts a lot of combustion can re-use the carbon-monoxide (by-product) to produced methanol by the hydrogenation of the carbon-monoxide (University of York, 2014). Waste-to-energy Conversion and Recycle: In certain circumstances, the energy needed to recycle the waste product maybe significant compared to the advantages of the recycled product therefore it may be considerable better to convert waste to energy. Recycle and converting waste to energy should be interchangeable. For example, the production of cotton with the use of pesticides and fertilisers could end up requiring more energy and polluting more than the production of certain artificial fibres or fabrics (University of York 2014). Landfill: this is often regarded as the most cost-effective way to dispose selective chemical waste especially in countries like America and Nigeria with large open fields. With other waste management methods such as incineration and resource recovery both requiring wide investments in manpower and infrastructure, landfills have fewer cost, allowing them to stand favourably. They can also be upgraded to generate natural gas which can be potentially seen as revenue stream (Blackstone 2015). 4. SAFER SOLVENT As part of the means to preserve the environment and to maintain the practises of a sustainable chemistry, it is preferable to conduct reactions that occur in a gaseous phase simply because they avoid the usage of solvents to bring reactants together. Examples of these processes include; the manufacture of ammonia, methanol, ethene and ethanoic. In the production of ethanoic, where possible, an alternative solvent which is not harmful should be used because the solvent readily evaporates into the atmosphere unless safety precautions are taken to contain them (University of York, 2014). CONCLUSION The four means of maintaining sustainability in the chemical industry as explained with example in the body of this essay would go a long way in preserving the environment and its ecosystem if kept in practise, particularly to the future generations. In addition, the need to equally emphasis and imbibe this practise in modern chemical processes is economical viable both to the chemical industries and to potential investors.

Consequences of Actions in Shakespeares King Lear :: King Lear essays

Consequences of Actions in Shakespeare's King Lear King Lear is a perfect demonstration of the great consequences one man's actions can cause. While there are certainly religious Christian elements to the story, the story is not one of morality or hope. King Lear is a lesson, making an example of what can come of a single, foolish, egotistical action. King Lear's action is the surrendering of his throne to his daughters. The element of Christianity enters here, because King is a God-appointed position, not to be given up. Lear, however, decides to disregard this fact, instead focusing on the immediate gratification he will receive from his daughters, and boosting his self-esteem while making him feel loved. Lear essentially offers his land and power for love, "Which of you shall we say doth love us most? That we our largest bounty may extend where nature doth with merit challenge," forgoing his God-given position and rights. Next enters the punishment, seemingly brought about by God. Because Lear has disregarded God's wishes, he is made to suffer insanity and excruciating physical torment. Lear is even given multiple opportunities to revoke his decision, but rather than heed the advice of those trying to help him, he banishes them for questioning his selfish decision. This leaves Lear surrounded by the people looking only to better themselves by using the now vulnerable Lear. Lear is estranged from his kingdom and friends, causing his loss of sanity. In the midst of Lear's self-pity he is discovered by the fool. Fittingly enough the fool is the one able to lead Lear back to the normal world. He is made to appreciate the people who truly cared about him from the beginning. He sees that they were right all along, and repents from his foolish decision, though it's too late to do him any good. Once more, the consequences of Lear's single sin are felt. In a typically Christian or hopeful ending, King Lear would learn to listen to the caring friends he has, and become less selfish. Shakespeare, however, chooses not to end it so predictably or simply. Even after all of Lear's suffering and repenting, he continues to receive punishment. Cordelia, who he has now realized truly loved him most, is killed. Lear is left feeling hopeless, saying, "I know when one is dead, and when one lives. She's dead as earth," which seems slightly to refer to his now cynical view of the earth.

Movie Yasmin Essay

‘Yasmin is remarkable as a film for its cinematic economy: not a scene, shot or speech is wasted. ’ Explore some elements of the film in relation to this statement. The movie Yasmin, released in 2004 and written by the highly acclaimed writer of The Full Monty, Simon Beaufoy, is an impressive drama about what it means to be an Asian-looking Muslim in Britain of the 21st Century. The story is about the young and vivid Yasmin, a woman who tries to â€Å"succeed, by the skin of her teeth,†[1] in the two worlds she grew up in.On the one hand there is her life at home with her believing father and rebellious little brother, for whom she has to mark â€Å"time as a dutiful Muslim wife until her arranged marriage can be terminated. â€Å"[2] On the other hand there is her life outside this domesticity, where she is â€Å"like a fugitive, maintaining a double life as she changes into Western clothes, wins employee of month award at work and goes to the pub with colleag ues. â€Å"[3] One of the main topics of the movie is the difficult tension between being a religious and respectful woman and integrating into the Western society.Another important theme in the movie is the impact that the terror attacks in September 2001 had on the British Asian community in Britain. Yasmin’s story therefore deals with a wide range of themes such as discrimination, guilt, and the progress of searching for one’s own identity. It is especially â€Å"remarkable as a film for its cinematic economy (since) not a scene, shot or speech is wasted. † There are no fill-ups in this movie, everything has a meaning. This essay will explore some carefully chosen scenes of the movie concerning its sometimes hidden or masked intention and meaning.It will therefore especially concentrate on the beginning scene, which is regarded as being â€Å"the strongest part of the film†[4]. A closer look at the opening of the film is worth it since every well comp osed novel or film is creating a deliberate relationship between the beginning and the rest of the movie. It will be examined in the following, that additionally in the case of Yasmin the directors develop a consistency, a pattern of the main themes of the film, in the beginning.Everything is already there in the very first three and a half minutes; things shown in the opening reappear later in the movie; conflicts the film deals with can already be assumed in moves, placements, and pictures. It will be proven that, if taken into account every detail, every shot of the scene, the viewer will already be able to see the whole film in miniature in the beginning. The essay will therefore also have a closer look on what is shown in the opening scene and will then search for coherences and connections throughout the rest of the movie.It will hereby not go through the scene chronologically but will pick up separate shots of it and put them together in categories; although it will start wit h the first shot to which the viewer is introduced in the movie. When Khalid, Yasmin? s father, lopes over a typical grey English street followed by Nazir, Yasmin? s brother, a few steps behind him, Nazir? s bearing strikes the viewer immediately: the way he creeps a few steps behind his father with the hands in his pockets expresses discouragement, maybe even irritation.He seems to be unhappy with the situation, possibly because it? s too early in the morning, since gentle beams of sunrise just touch the wall behind them; possibly because he dislikes the purpose of their walk. His father, however, hastens to raise this purpose: in his hurry he turns around to see where his son has got to. It becomes clear that it is the father who controls the situation— that he is the leader whom the son has to follow. So apart from the obvious, the authority person walking in front might tell the viewer something about the relation between father and son.One could even go further and sugge st it might also tell something about their attitude towards life, about their religion, about the way the head of the family is treated in the Islam faith. The scene therefore implicates the parental respect of which is set value in this family. How important this topic is to Yasmin? s father Khalid becomes more and more clear during the course of the movie: he repeatedly calls for respect towards the parental authority over his children. When Yasmin is complaining about her husband and gives him humiliating names, Khalid reprehends her immediately and stresses his will with a slight slap.He even repudiates Yasmin when she dares to apply for a divorce against his will. So the viewer already gets in this very first scene, in the very first seconds, an initial impression of what domestic life in this family is about: about respect and family ties. The two move on and finally arrive at the mosque, which is gated by a metallic blind. After abandoning their shoes, Nazir and Khalid enter the interior of the mosque; and in doing so they pace over a formidable carpet in a remarkable red. It s admirable how strikingly this little scene influences the movie? s atmosphere: after the grey and dusty outside of the mosque with its bleak stone-walls and metallic blinds covering the entrance, the viewer now gets an impression of the inside; the colourful, bright, shining red carpet. The jump is a quiet astonishing little moment: the greyness outside opposes the bright shining colour of the huge carpet these seemingly little people are crossing (amplified by the way the scene is shot: with bird? eye view). Inside the mosque the viewer gets a sense of richness, a glimpse on the whole tradition, an idea about the Islam faith. The scene is not just remarkable because of its visual orchestration, but also in introducing the viewer to this huge and rich religion and the way it sees the world. Later in the beginning scene there is a shot that shows the grey and grim wall of a Yorks hire stone house in the front, again contrasted by the beautiful outlines of the colourful mosque in the background.The two absolutely different styles of architecture standing next to each other implicate a huge imagery: the mosque as a symbol for the tradition and a stonewall which symbolizes the here and now, indicates how the life of the Muslim people in Great Britain stands side by side with the traditional life of the British natives. This deliberate expression of a coexistence of the two traditions is an expression of crossing cultures at its best in this movie, and at this point of the movie it also stands for a successful integration of the Muslim tradition into the British society.This impression is furthermore stressed during the course of the beginning scene: the mosque is using modern techniques; it is using the loudspeaker, the microphone, so a lot of quite modern technology. Satellites are shown. Here the movie is not only supposing the ageing culture of Islam against the modern British culture of science and technology but goes further: it brings it together. There is an interchange going on here through what the viewer can hear (the singing of Nazir) and what he can see (the loudspeakers and satellites).By bringing these aspects together at the same time the fusion becomes immediately clear to the viewer. In another shot of the beginning scene the viewer observes the vivid life of the Muslim community that is taking place in the streets of the town. Even though one quickly might suggest that this shot might be just a fill-up it, in fact, goes further: the viewer here gets an impression of what the life in this Muslim community is like. The reason for that is that later in the film, after the 11th of September 2001, the same streets are depicted deserted, isolated, dead.Whereas the beginning scene expresses the successful integration of the Muslim tradition into the British society, the contrasting scene in the middle of the movie now stands fo r the failure of this coexistence, for the loss of community. The remarkable contrast of this two scenes is to â€Å"illuminate Muslims' increasing disenchantment with Western society†[5] after the terror attacks. So it now comes clear that nothing in the movie is there without reason: showing a typical East-Asian community in a British town is not a fill-in but is a part of the whole effort of later showing a community being disrupted. Nothing in the movie is wasted.One of the most impressing returning scenes of the movie is Nazir singing in front of the microphone. Also this theme is introduced in the beginning scene: after watching the film the first time, the peaceful scene in the beginning immediately reminds the viewer to the very last scene in the movie, when Khalid, the father is putting in a tape into the recorder as an ersatz for the son. This final scene has a huge impact on the viewer since one here really realizes that Nazir has gone off and will not come back. I t is therefore a really tragic little moment: it is emotional even though there is no actor playing the emotion.What is on the first glance less striking but not less important is that the image of the son singing comes back three times during the course of the movie; in the beginning, in the middle, and in the end. It runs through the film like a red thread: in the beginning it is, as said, introducing not only to the family? s religion but also to the family background itself. In the scene in the middle of the movie Nazir, before he starts, coughs as if he smoked too much. Since the viewer knows that he started â€Å"indulg(ing) in petty drug dealing and consorting with local girls†[6], it seems as if he became corrupted by what he is doing with his life.His coughing therefore is again not without meaning but stands for Nazir? s life becoming more difficult to handle. The returning scene is a marker in the film and each time it means something different: in the beginning it is quite straight forward, in the middle it appears as a comment for what happened to Nazir and his life, and in the end it is tragic since he is gone and will never come back. So as a major thread throughout the movie the scene with the singing Nazir displays the different states the movie and its protagonists are currently in. A similar red thread s the theme of dressing and clothes that recurs throughout the film and, again, the theme is already introduced in the opening. By watching Yasmin changing her clothes hidden by one of the typical grey stone-walls one gets an impression of this girl transforming herself into another person. Yasmin makes an enormous effort of putting herself into the trousers, since they are really too tight. She tries hard to fit herself in, she even has to jump up and down. The connection is easy to make: this movie is about someone who tries to fit in with two different worlds, tries to force herself in.So here the choice of incredibly tight trousers simply indicate what Yasmin really wants: she wants to make herself fit. If something returns deliberately, a number of times, during the film it becomes a symbolic act: when Yasmin for example dresses up to revolt against her father later in the movie, it symbolizes Yasmin? s wish to break out, to be able to be herself. In the end of the film she switches to traditional Muslim clothes, since she is at this point of the movie staying in the side of the traditional. Here the clothes express how a religious thought became fixed and hardened. Dressing here becomes a signifier for her state of mind.Since it returns later in the movie several times it always tells the viewer something when it comes to clothes. So by following how the dressing in this movie changes throughout the plot one gets a neat impression of how the state of Yasmin’s mind changes with it. The clothes are never chosen without reason in Yasmin, there is an intention in every piece the actors wear. Even though i t is just a little detail it strikes the viewer and is therefore very well-thought. So after Yasmin changed her clothes she turns over to her car and plays around with it: she locks and unlocks it with her remote control several times.This car is, as Yasmin later in the movie declares, not a ? t. p. car`, a ? typical paki-car`, but a sporty, feminine little cabriolet in an outstanding red. With this car, she wants to separate herself from those typical Pakistani people, and, even further, wants to declare her independence: â€Å"it gives her a life away from her husband and her home†[7]. By buying this car she is able to show herself and everybody else that she is different, what makes it an act of almost deliberate despair. But on the other hand, by playing around with the car, she expresses her excitement.She does it simply because she can. This gives the viewer a sense of how she is playing with things she owns, how she creates the parts of the world around her she can con trol in the way she likes it. The motif also returns later in the movie, after 9/11: Yasmin gets in the car and there is a news report on the radio about the terror-attacks. Yasmin? s reaction is as playfully as in the beginning of the movie: she just puts a CD in, and listens to the music. She does simply not want to think about, does not want to care. The viewer gets an impression of the ambiguity of Yasmin? life, of how difficult it must be to live in two different worlds, to create her life successfully around the different expectations the people she deals with have of her. The last shot of the opening scene in the movie depicts this challenge in a deliberate way: it shows the long, small, winding road Yasmin has to take day by day to drive to work and back. This road is the connection of the two worlds she lives in; it is a connecting thread between not only two different locations but two different worlds. Yasmin is having this journey – this transformation, this strug gle – every day.By driving over this street she is migrating from one world to another and she has to transform herself before she is accomplished with the migration, since she changes her identity day by day. Furthermore the road is connecting the two different worlds as well as dividing them. That becomes clear through the visual impact of this shot: the road is crossing the whole screen and Yasmin and her little car have to follow its way through the landscape; it deliberately makes the viewer ask: how long will it take her? And how long will she stand this?The struggle of â€Å"balancing two separate worlds in quest to please (a) conservative family, without sacrificing the obvious advantages of the Western environment†[8] is depicted as lovely and rich in detail in the movie Yasmin. It is â€Å"the beautifully realised opening, entirely without dialogue for a good few minutes, (that) is the strongest part of the film†[9] as it, as shown, already gives the w hole of the movie, its main conflicts, themes and topics in miniature. Although this is a primarily visual scene, dialogue, if used in the movie, is very effectively— â€Å"Not a scene, shot or speech is wasted. But the dialogue is used economically and not in the opening: it is a visual opening; in general, Yasmin is a visual movie. Every scene, every act, every piece of clothing has a meaning. As the director of the movie, Kenny Glenaan himself, says: â€Å"obviously the beauty is what you can do within the frame and some people are amazing at doing that. â€Å"[10] Bibliography Dilks, Richard, Yasmin, in Close-Up Film, 2003, http://www. close-upfilm. com/reviews/y/yasmin. htm Docherty, Alan, Yasmin – Kenny Glenaan, in Culture Wars, 2001, http://www. culturewars. org. uk/2004-02/yasmin. tm Glenaan, Kenny, in a BBC Interview, last updated in September 2004, http://www. bbc. co. uk/films/festivals/edinburgh/yasmin. shtml Jennigs, Tom, Tom Jennings’ essay on c inema representations of European Asians & Muslims, 2005, http://libcom. org/library/ae-fond-kiss-dir-ken-loach-yasmin-dir-kenny-glenaan-head-dir-fatih-akin-film-review The Hindu Magazine, Being Asian, Muslim and British, Online edition of India's National Newspaper, 2003, http://www. hindu. com/mag/2004/11/14/stories/2004111400270200. htm ——————————— [ 1 ].Docherty, Alan, Yasmin – Kenny Glenaan, in Culture Wars, 2011, http://www. culturewars. org. uk/2004-02/yasmin. htm [ 2 ].
