Proposal Submission Letter

Sample Cover Letter The Virtual Community Group, Inc. 17 Park Road Rural Town, NH July 1, 1995 Jane Smith, Executive Director Xavier Foundation 555 S. Smith St. Washington, D. C. 22222 Dear Ms. Smith, I am pleased to submit this proposal from the Virtual Community Group, Inc. , requesting an investment of $50,000 per year over two years from the Xavier Foundation to support our Enterprise 2000 initiative.This grant would provide part of the funds needed for us to train at least 1200 low-income entrepreneurs in rural New Hampshire, helping them acquire the computer skills they need to create sustainable local businesses as we enter the twenty-first century. As elsewhere in the U. S. , the economic health of New Hampshire's rural communities has suffered steady decline since the early 1900's. Family farms, which once formed an economic base supporting large numbers of rural inhabitants, have been all but eradicated by large-scale agribusiness.Moreover, since 1960, New Hampshire has los t xx% of its manufacturing jobs, as corporations or local factories have shut down or moved operations out of state. As a result, many thousands of individuals from New Hampshire — particularly our young people — are moving to cities to seek jobs, not only depopulating and further impoverishing rural communities, but contributing to the growing pool of urban unemployed.By tapping the energy of the small local entrepreneur, and linking it to the explosion in communications technologies, we believe it is possible to reverse this trend, enabling rural inhabitants to retain viable, high-quality jobs far from industrial and urban centers. Small towns would again offer a wide spectrum of employment opportunities — from small manufacturing to services to retail — and develop sound, diversified economies for the first time in generations. Unfortunately, many small entrepreneurs cannot afford either the training or equipment needed to participate in the rewards of the Information Revolution.Enterprise 2000 was designed explicitly to address this lack of parity, and help level the communications playing field. Working in collaboration with microenterprise organizations, community colleges, and agencies which recycle computer hardware, Enterprise 2000 will offer disadvantaged entrepreneurs the following services at low or no charge: †¢Day-time or evening classes in basic, intermediate, and advanced computer skills †¢Training to use the Internet and other information networks †¢Assessment of MIS needsAccess to reconditioned computer hardware After two years of experimentation and program development, the Virtual Community Group has fashioned a superb, easily replicable model in Enterprise 2000, and established a high degree of credibility among community groups, policy makers, and funders. Our collaboration with other agencies leverages every dollar invested.Given that the Xavier Foundation has already made a number of strategic investments to improve the lives of the rural poor, we are calling on you to help us advance our joint objective one step further. I appreciate your consideration of this proposal. Please feel free to call me if you have questions or would like us to arrange a site visit. I look forward to meeting with you soon. Sincerely, Executive Director (This sample cover letter was created for AGM by Molly Clark Associates. )

Evaluation of teaching Essay

In groups students will successfully complete a procedural checklist/guide and then demonstrate the procedure following the checklist meeting the following criteria: Note made of all material needed for the procedure. Procedure for preparing the environment and the patient for the NG tube insertion described and performed satisfactorily. Each step for NG tube insertion outlined and followed, in PRECISE order, and with correct technique. All necessary checks and appropriate precautions required during and at the end of the procedure are made and reasonable justification given for why such precautions were necessary. Detail made of two scenarios that may be presented (e.g. ph above 6) and alternate steps or procedures that should be followed. While the student is demonstrating the procedure the teacher will be observing the demonstration. You have a checklist with the above criteria A-E and you award a mark on a scale of 1 to 5 to say how well the student is meeting each criteria. For example in C does the narrator and the demonstrator follow each step correctly or do they mix the steps up. Do they forget to do something that they are supposed to do like check for any obstructions in the nose and throat? The students are rated for each of the criteria and given a mark out of whatever mark you want to give. This mark does not even have to be written down but you just have it in your head that the persons performed the tasks excellently, good, fairly well or very poorly. You will use both demonstration and the checklist as the basis for your evaluation. If you collected the checklist that the students did then evaluation of this could be done separately. Basically the students should follow the procedure the same way you demonstrated it and based on how well they follow instructions you will know whether or not they understand and can perform the procedure. If you need additionally clarification please send a message to me on the system.

CyberCrime Law Essay

The Cybercrime Law of the Philippines (also known as the Cybercrime Prevention Act of 2012 or Republic Act 10175) is a newly-signed act that gives us a true legal tool to combat cybercrime. A better definition is given by a press release from the Senate, a part of which says, â€Å"The Cybercrime Prevention Act lays down a comprehensive legal framework for the detection, investigation, and suppression of cybercrimes†¦Ã¢â‚¬  The Republic Act No. 10175, also known as the Cybercrime Prevention Act of 2012, is an act that defines and punishes cybercrime to prevent and suppress its proliferation. It aims to effectively prevent and combat misuse, abuse and illegal access of the Internet by facilitating their detection, investigation, arrest and prosecution at both the domestic and international levels, and by providing arrangements for fast and reliable international cooperation. To formulate and implement a national cyber security plan, a Cybercrime Investigation and Coordinating C enter (CICC) will be created under the administrative supervision of the Office of the President. This Act is authored by Reps. Susan Yap (2nd District, Tarlac), Eric Owen Singson, Jr. (2nd District, Ilocos Sur), Marcelino Teodoro (1st District, Marikina City) and Juan Edgardo Angara (Lone District, Aurora). Other authors of the bill are Reps. Gloria Macapagal-Arroyo (2nd District, Pampanga), Diosdado Arroyo (2nd District, Camarines Sur), Carmelo Lazatin (1st District, Pampanga), Rufus Rodriguez (2nd District,Cagayan de Oro City), Maximo Rodriguez, Jr. (Party-list, Abante Mindanao), Mariano Michael Velarde and Irwin Tieng (Party-list, BUHAY), Romeo Acop (2nd District, Antipolo City), Bernadette Herrera-Dy (Party-list, Bagong Henerasyon), Anthony Rolando Golez (Lone District,Bacolod City), Juan Miguel Macapagal-Arroyo (Party-list, Ang Galing Pinoy), Ma. Amelita Calimbas-Villarosa (Lone District, Occidental Mindoro), Antonio Del Rosario (1st District, Capiz), Winston Castelo (2nd District, Quezon City), Eulogio Magsaysay (Party-list, AVE), Sigfrido Tinga (2nd District, Taguig City) , Roilo Golez (2nd District, Paraà ±aque City), Romero Federico Quimbo (2nd District, Marikina City), Mel Senen Sarmiento (1st District, Western Samar), Cesar Sarmiento (Lone District, Catanduanes), Daryl Grace Abayon (Party-list, Aangat Tayo); Tomas Apacible (1st District, Batangas), Jerry Treà ±as (Lone District, Iloilo City), Joseph Gilbert Violago (2nd District, Nueva Ecija), Hermilando Mandanas (2nd District, Batangas), Ma. Rachel Arenas (3rd District,Pangasinan) and Ma. Victoria Sy-Alvarado (1st District, Bulacan) The newly approved law aimed at combating cybercrimes has been met with mixed reactions from the public and private sectors. This Prevention Act is a boon for local firms, particularly in the information technology sector, business groups said. Other groups meanwhile warned that the new law threatens Filipinos’ freedom of expression as well as freedom of information. But what does the anti-cybercrime law mean for the ordinary Filipino citizen? Most if not all of the offenses in the law are already crimes punishable under the Revised Penal Code. Commenting on the new law, Information and Communications Technology Association of the Philippines (ITAP) President Dondi Mapa said: â€Å"It’s not a matter of identifying new crimes but only recognizing that existing crimes now happen in a new environment.† The anti-cybercrime act itself notes under its declaration of policy that it is the state’s mechanism to adopt â€Å"sufficient powers to effectively prevent and combat such offenses by facilitating their detection, investigation, and prosecution.† The law categorizes cybercrimes into three: (1) offenses against the confidentiality, integrity and availability of computer data and systems; (2) computer-related; or (3) content-related offenses. Illegal access to computer systems, illegal interception of data, data or system interference, as well as misuse or computer systems or data belong in the first category. Also in the same group is â€Å"cyber-squatting,† which involves the acquisition of a domain name â€Å"in bad faith to profit, mislead, destroy reputation, and deprive others from registering the same.† In case of businesses, these may include the use of a domain name â€Å"similar, identical, or confusingly similar† to registered trademarks. But businesses are not the only targets of â€Å"cyber-squatters,† as the law also covers the use of personal names â€Å"identical or in any way similar with the name of a person other than the registrant.† Computer-related offenses, meanwhile, include the input, alteration or deletion of any computer data with the intent of forgery, fraud or identity theft. On the other hand, cybersex, defined under the law as the willful engagement in online sexual activities, is included in content-related offenses. Child pornography is another content-related offense in the law. The anti-cybercrime act notes that punishment to child pornography committed through a computer system will be one degree higher than the sanctions in the Anti-Child Pornography Act. Also named a content-related offense is the sending of unsolicited communication which advertise or sell products or services. Punishable acts Offenses punishable under Cybercrime Prevention Act are: * Offenses against the confidentiality, integrity and availability of computer data and systems 1. Illegal access to the whole or any part of a computer system without rights 2. Illegal interception of any non-public transmission of computer data to, from, or within a computer system 3. Data interference such as alteration, damaging, deletion or deterioration of data without rights, including the introduction or transmission of viruses 4. System (computer or computer network) interference 5. Cyber-squatting or the acquisition of a domain name over the Internet in bad faith to profit, mislead, destroy reputation, and deprive others from registering the same 6. Misuse of devices * Computer-related offenses 1. Computer-related forgery (input, alteration, or deletion of data) without rights resulting in inauthentic data, with the intent that it be considered or acted upon for legal purposes as if it were authentic 2. Computer-related fraud (input, alteration, or deletion of data or interference in the functioning of a computer system) causing damage 3. Computer-related identity theft or the acquisition, use, misuse, transfer, possession, alteration or deletion of the identifying information of another person * Content-related offenses 1. Cybersex or the engagement, maintenance, control, or operation of any lascivious exhibition of sexual organs or sexual activity, with the aid of a computer system 2. Child pornography or the unlawful acts as defined and punishable by Republic Act No. 9775 or the Anti-Child Pornography Act of 2009 committed through a computer system 3. Unsolicited commercial communications which seek to advertise, sell, or offer for sale products and services 4. Libel or unlawful acts as defined in Article 355 of the Revised Penal Code * Others 1. Aiding or abetting in the commission of cybercrime 2. Attempt in the commission of cybercrime Penalties * Any person found guilty of committing cybercrime acts enumerated in the first two groups shall be punished with prisons mayor, or serving of six years and one day to twelve12 years in prison, or a fine of at least PHP 200,000 up to PHP 500,000. * A person found guilty of committing punishable acts enumerated in the first group shall be punished with reclusion temporal, or serving of 12 years and one day to 20 years in prison, or a fine of at least PHP 500,000 up to the maximum amount in proportion to the damage incurred, or both. * A person found guilty of committing cybersex shall be punished with prisons mayor, or serving of six years and one day to 12 years in prison, or a fine of at least PHP 200,000 but not exceeding PHP 1,000,000, or both. * A person found guilty of committing child pornography shall be punished with the penalties enumerated in the Republic Act No. 9775 or the Anti-Child Pornography Act of 2009. * A person found guilty of committing unsolicited commercial communications shall be punished with arrest mayor, or serving of one month and one day to six months, or a fine of at least PHP 50,000 but not exceeding PHP 250,000, or both. * A person found guilty of committing other offenses enumerated in the last group shall be punished with imprisonment one degree lower than that of the prescribed penalty for the offense, or a fine of at least PHP 100,000 but not exceeding PHP 500,000, or both. Unfortunately, questions remain over the constitutionality of the law. It doesn’t help that there are people who still think they can use the law, especially a judge in Nueva Vizcaya who had an anti-mining protestor jailed over the basis of cyber libel, one of the crimes made punishable by the controversial act. But what â€Å"crimes† specifically does the suspended law target? Someone asked me for a breakdown of what is (or isn’t allowed) by the Cybercrime Law. Hereâ€℠¢s a layman’s version of what the law entails, which I call: The 10 Commandments of the Cybercrime Law of the Philippines. 1. You shall only say nice things on the Internet–This is the main fault attributed to the law: It’s a violation of the Freedom of Expression with its cyber libel provision. Thanks to this provision inserted â€Å"without knowledge† by most of the lawmakers, if you say something bad against certain people on the Internet, you can be charged in court. What’s more, according to Bayan Muna Representative Teddy Casià ±o, this not only applies to statements you make on the Internet but also on smartphones or with any device you use to access the Internet. So yes, this covers texting. 2. You cannot tell the Truth, whether joking or seriously, if it hurts someone–In relation to the 1st Commandment, regardless if you state a fact or you use satire or sarcasm or even say something in a joking tone on the ‘net, you can still be held liable for cyber libel for impugning against another person’s supposed dignity as per the anti-libel law of the Re vised Penal Code. 3. What you say can be held against you forever–According to online legal expert Atty. JJ Disini, because of the nature of your online posts, anything you posted years ago that are still live today can be still held against you in a court of law. 4. What you like can also be held against you–In relation to the 3rd Commandment, liking a FB post can be considered as abetting libel. Retweeting a probably libelous tweet might be covered here as well so be warned. 5. The government now has the power to take down your Internet–Thanks to the power given by the law, the Department of Justice, together with its arms in the National Bureau of Investigation and the Philippine National Police have the power to order the shutdown of Web sites if there is prima facie evidence of violation of the law–even without a court warrant. 6. Your Internet is required to compile evidence against you–In relation to the 5th Commandment, Internet service providers are now requ ired to keep their data for six months after which they can be forced to keep it for six more months if authorities request it. 7. You can be punished more harshly for online crimes than for real life crimes–Thanks to the wording of the law, punishment for those charged with this law is â€Å"one degree higher† than that provided for in the Revised Penal Code. Because of this, if you’re charged with online libel, you can be fined a million bucks or spend 12 months in jail. 8. You must trust the government to do the right thing in implementing the law–The government refuses to budge on this law, saying the public should trust them to come up with the proper Implementing Rules and Regulation to ensure that there won’t be abuses of the law despite the vague wording. This after the some of the lawmakers who signed the law admitted they had no idea what had gone into the law. 9. The law shall apply to all Filipinos wherever they are–Just because you think you’re not in the Philippines, you can escape jurisdiction from this Philippine law. Think again: this law has universal jurisdiction. Even your electronic devices that are situated (or even partly) in the Philippines are under jurisdiction under this law. 10. The law doesn’t really protect you–Supposedly it goes after identity-theft. However, because of the heavy provisions against online libel, a hacker can take over your account and post libelous stuff, and then pull out. From the safety of distance, he can watch the fireworks fly as the government screws you over. So yes, it can protect industries and the rich and powerful, just not you. Of course there are other issues over this law. One is that the basis for its cyber libel provision is the antiquated anti-libel law in the Philippines (which the United Nations pointedly reiterates as violating respect for freedom of expression). And there lies the irony of this law: In trying to implement tighter data security and prevent cybercrime laws like cybersex and child pornography in the country, the Philippines are using vague language like a sledgehammer to go after cybercriminals. Unfortunately, the government doesn’t seem to have any idea of the power of words–whether specific or vague–and how dangerous they can become when implemented as laws.

Food mart Essay Example | Topics and Well Written Essays - 500 words

Food mart - Essay Example Because the order quantity that he desired was not available at the closest store possible, Foodmart cannot be considered to have ripped Todd off by not having the correct amount of chocolate sauce on stock. Todd may not have been aware at the time, but Todd entered into a contract with Foodmart that contained several terms and conditions. This is not a special case; every customer who purchases items online need to be aware of all the fine details of the contract that they are entering into. For Foodmart’s online order contract, the customer cannot purchase items that were advertised for cheaper in print. In addition to this stipulation, the online sales contract states that orders placed online can only receive inventory that is available from the closest store in terms of location. Thus, Foodmart cannot be held accountable as they laid out all the terms and conditions in their online contract. If the customer chooses not to take notice of this, then it is solely the custome r’s responsibility and the company at hand cannot be held responsible. If the company chooses to reimburse Todd then that is their choice, but they have no legal obligation to do so. It may be to the company’s benefit to reimburse him once because he may prove to be a long-term customer. The benefits in this case may outweigh the negatives so it may be best to give Todd the benefit of the doubt this time only. If he is in a similar situation again, then Foodmart should advise him that there is nothing that they can do for him. Foodmart should try to avoid such a situation in the future by making its customers aware of the terms and conditions of any contract. This would avoid legal issues down the road and it would give assurances to a customer that everything will be done through legal means. Foodmart could make it easier for customers by writing its terms and conditions in simple and easy to understand words so that

Effects of Global Warming on Parks, Recreation and Tourism Essay

Effects of Global Warming on Parks, Recreation and Tourism - Essay Example The irony is that tourism itself is contributing to the very process that threatens it. Tourism relies on cars and buses, air-conditioning and air travel all of which release warm gasses. It accounts for about 5% of the world’s carbon dioxide emissions (Rosenthal, 2007). Tourism is significant for the global economy but there is an interrelationship with the climate. Global warming is a challenge for the tourism industry in the mountain areas but it results in the long summer season. This makes it interesting to concentrate on the effect on mountain tourism and then generalize on the overall impact on the tourism industry. Global mean temperature has increased by about 0.6 - 1Â °C over the last 100 years and will increase in the future as well. The temperature would further increase from 1.4 to 5.8Â ° until 2100 (Burki, Elsasser & Abegg, 2003). Global warming will be stronger on the land surface, the northern hemisphere and in winter, which means the summer season would be l onger. In the alpine areas, the financial viability of winter tourism industry depends on skiing, snowboarding, snowmobiling and cross-country skiing. Warmer temperature would affect ski tourism in mountain areas. Swiss glaciers have been steadily losing their surface since 1850 and it is expected that by 2030, 20 to 70% of the glaciers would have disappeared. Not only the mountain aesthetic is lost skiing slopes too are affected. Mountain areas become vulnerable to landslides and the cableway stations become unstable. Fog level would increase which would mean more summer tourism like hiking, trekking or biking. With warmer winters ice fishing would be impossible. Burki, Elsasser, and Abegg, however, contend that the climate change has been exaggerated by the media, science, and politics.

Elements of Religious Traditions Research Paper Example | Topics and Well Written Essays - 750 words

Elements of Religious Traditions - Research Paper Example The paper would discuss its relationship with various elements of social interaction. Identifying critical issues God is a supreme being in different religions vis-a-vis Christianity, Islam, Hinduism, Judaism, Buddhaism etc. The varying traditions and their interpretations therefore become critical issues to define human behavior and actions, especially with regard to various socio economic and political paradigms which have catalytic effect on all people cutting across nationality, race, culture and color. The racial prejudices, gender inequality, capitalistic structure of society and even national boundaries are seen as going against the basic posit of religions’ core beliefs. This also raises the need to examine religion in various perspectives to gauge its responses amongst the people who practice it in different format and expressions. Relationship with divine God’s supremacy is recognized within all religious scriptures and exemplifies its relationship with the Di vine in terms of behavior that is morally and ethically correct. The Bible teaches to be God fearing and stresses the need to repent by the sinners. It believes that God has endowed man with free will so he can follow his course of actions that would lead him towards the God. The sinful acts would lead him to purgatory and therefore repentance becomes intrinsic part of Christianity. Hinduism also reveres God as Creator and inculcates God fearing tendencies for fear of going to hell rather than heaven. Thus, in all religions, good actions are encouraged because they bring men closer to God. Relationship with sacred time Religious traditions and scriptures are abound with the notion of eternity and the scientific theory of evolution of man which has faced tremendous pressure from the Church and other religions. The theory of creation and orthodox Jews beliefs that ‘our history had been preceded by untold cosmic cycles of millions and billions of years’ (N.d, 2010, reading 1). The Hinduism’s concept of rebirth delineates the concept of time to surreal realities which are but the imagery of our physical self. In religious traditions, sins and purgatory would invite wrath of God, resulting in ultimate destruction of the world. The sacred time, therefore is important aspect where events occur in cyclic order irrespective of the fact whether it is desired or not. Thus, prayers become important part of religious traditions. Relationship with sacred space or natural world World is created by God and Human beings are called to work as God's stewards. The created order is entrusted to humanity, not as individuals, but as a community. The private property right is therefore embedded in an inclusive concept of common property of all people and is never allowed to become an absolute right that excludes others completely (Graafland, 2008, reading 3) Religious conceptualization of space and natural world delimits the manmade boundaries of nations. Everythin g belongs to God and respect and healthy regard for all elements of the earth become intrinsic to religious philosophy. Merleau-Ponty (reading2, 1965) says that there are two world, one external that needs space or territory and the internal one or ‘agora’ that resides within oneself. Agora continuously provokes people to move and thereby ‘

Industrialization After the Civil War Thesis and Outline Research Paper

Industrialization After the Civil War Thesis and Outline - Research Paper Example 201). There was also an impact in machine tools. On the other hand, due to the machine tools impact many people lost their jobs, because of the growing number of qualified engineers needed and the growing number of immigrants who were unqualified workers (U.S. Bureau of the Census, pp. 19-20). What is more, even though oil was already known to public, the first modern oil well was set up in 1859 by Edwin Drake (Vassiliou, p. 13). Invention of the steam engine made transitions by water easier and cheaper. There were many other great changes in industry and technology during mentioned period. However, many laborers in that time were displaced by machines and level of unemployment grown highly (Wells, p. 189). What is more, working on factory was dirty, dangerous and exhausting. Many employees moved to cities and came to work on factories, thus urbanization level grown. Although, labor productivity grown owing to increasing number of system was built in 1890. Although Thomas Edison did not create the first electrical light bulb, it is his patent, which lead to lighting people’s houses in 1883 (Thomas Edison: Life of an Electrifying Man, p.15). Started in 1870s African American lost some of their rights and been harassed. It has led to a politics of racial segregation. Woman were granted full righting votes in some states by the end of 19th century. Entrepreneurs started to use child labor because they are small and could get to smaller holes than adults could. Extended families became more common than nuclear ones. To make a balance, I would like to say that Industrialization occurred after the Civil War had a great influence on American industry, technology and society. It had its pros and contras, however I consider that pros outweigh

International Marketing Communications Plan 03062 Essay

International Marketing Communications Plan 03062 - Essay Example tage comes from its emphasis on social responsibility, ethical trade and delivering value to customers who believe in the same values as The Body Shop. The marketing plan proposes to use these values as a pillar to form the marketing strategy which would be directed towards the younger segment that is prone to adopting new trends early. The Body Shop International was set up by Dame Anita Roddick and sells skin and beauty products. The brand combines activism and marketing to encourage men and women to focus on social and environmental issues. The brand operates in 60 markets worldwide and has more than 2500 stores that work on a franchise based model. They also have the new Hemp Body Care line and The Body Shop at Home line as well. (The Body Shop, 2015) The brand believes in fair trade and has set up its own fair trade program called Community Fair Trade. This program involves 30 suppliers in 20 countries and provides 25,000 people worldwide with income to build their future. The Body Shop also sources its raw materials from their suppliers (The Body Shop, 2015). Since 1994, The Body Shop has helped raise funds and awareness for domestic violence. Since 2004, over 4 million pounds has been donated to partners who prevent, support and protect women and children from domestic abuse (The Body Shop, 2015). Protecting the planet is an important value for the Body Shop. They take full responsibility of their carbon footprint and aim to minimize their impact on the planet. This includes plants to reduce energy consumption and waste generation and change attitudes around the world about ecofriendly products (The Body Shop, 2015). The Body Shop does not face competition from well-known brand names like Mac, Sephora or Chanel because its product offerings and target market is different. In China, the competition comes from brands that originate from Japan or Korea like Missha or the Face Shop. These brands have already established a presence in the Chinese market and

Understanding Cryptography Essay Example | Topics and Well Written Essays - 1000 words

Understanding Cryptography - Essay Example Cryptography is somehow omnipresent going beyond the conventional environments such as banking systems, government communications among others (Christoff, 2009). Cryptography is now used in web browsers, cell phones, e-mail programs, embedded software, manufacturing systems, cars, medical plants, smart buildings among others (Christoff, 2009). Therefore, designers and system users need to understand comprehensively the concept of cryptography and how it is applied in order to appreciate its effectiveness in securing wireless networks and communication. According to Christoff (2009), cryptography is the study and practice of techniques for securing communication particularly in the presence of a third party (adversary). Essentially, cryptography is mainly concerned with the development and determining protocols that protect against the influence of third parties in communication and networking. It also analyzes protocols and mechanisms that are related to information security aspects including data integrity, confidentiality, non-repudiation and authentication (Paar & Pelzl, 2010). Over the years, various techniques similar to encryption have been used as cryptography. However, modern cryptography borrows from disciplines of computer science, mathematics and electrical engineering among others. Cryptography is predominantly used in computer passwords, e-commerce, and ATM cards. It employs several tools and techniques to implement the security needed for the various applications (Christoff, 2009). OpenSSL is one of the tools of cryptography that implements the SSL and the TSS security protocols in the network (Viega, Messier, & Chendra, 2002). It is mainly used in many web servers to transmit packets in encrypted form rather than in plain readable text. Open SSL has a core library that is developed in C programming language and is used for the implementation of the basic cryptographic functions and the

Life after death Essay Example for Free

Life after death Essay Life after death is credible to a large extent, as there is a large of percentage of people who believe in it. A study carried out between October and November 2009 showed that out of 2,060 people, 53% believed in life after death, with 55% believing in heaven and 70% believing in the human soul in the UK. However, there are many problems with believing in life after death – not least the fact that there is no proof. As Hume might have said, ‘there aren’t enough witnesses’ and ‘testimony isn’t proof. ’ Some evidence put forward is parapsychological, such as near-death experience, mediums, and so on, though the data generated from such evidence is contested. While there may not be any hard evidence for rebirth, it provides advantages to those who believe in it, therefore attaining the label of credibility. For instance, there is an idea of moral value because if one is constantly reborn, one must constantly strive for good karmic effects. However, G. E Moore’s theory of ‘naturalistic fallacy’ might intervene because rebirth confuses moral ideas with factual information about how the world works. There is no means of verifying the principle of karma, and it assumes a dark view of reality with the inevitability of suffering. On the other hand, there is some psychological truth in the ideas of anatta and anicca, since an individual continues to grow throughout their life. Resurrection also delivers benefits for those who believe in it, thus making it credible to a large extent. It has a basis in tradition and is supported by evidence from Sacred Scripture, while it is also fair and encourages morality. However, many challenges to belief in resurrection have been centred on the fact that there is no available way to falsify claims concerning life after death. But, non-Christian sources agree that Jesus was executed by crucifixion and his disciples believe that he rose from dead. A Church persecutor, Saul of Tarsus, unexpectedly transformed into a believer after the resurrection. Verification is only possible in the weak sense of eschatological verification suggested by John Hick in his Celestial City analogy. John Hick is a materialist, who believes that the soul and the body are ‘psycho- physically’ unified. Hick explains in his Replica Theory, where he discusses how God makes it possible for people to be ‘replicated’ on a parallel universe. Hick talks about how the instantaneousness replication would be different from simply being transported from London to New York, he says all the individuals would know their dead and would be on a world populated by deceased individuals. His theory could be seen as incoherent because there is no evidence in science to suggest there is a parallel universe, however if you accept God’s omnipotent existence, this theory is plausible and does not depend on dualism. But, even Hick recognised the limits of his own theory and the fact that it is hypothetical in the extreme. It should be noted that this is an extending theory into the unknown and is purely hypothetical. To conclude, life after death is credible because believers avoid the limitations of rationality and focus on faith, rather than empirical evidence. While some philosophers like Bertrand Russell, argue that the hope of a better life in heaven relieves humans of responsibility for what happens on Earth and encourages a fatalist mentality, such beliefs may do the opposite and soothe fears of demise.

Four Stroke Four Cylinder Petrol Engine

Four Stroke Four Cylinder Petrol Engine ABSTRACT Since last 150 years different type of engine used in different vehicles so one should know how the engine works and different parameters related to it. This project contains preparation of experimental setup to determine the various performance parameter of four stroke four cylinder petrol engine in first stage of project. In this stage of project, the Morse test setup with Rope brake dynamometer will be prepared for the measurement of engine performance parameters such as Break power, Indicated power, Friction power, Mass flow rate, Brake thermal efficiency, etc. In the second stage study of existing engine and scuderi split engine to be done and effort will be done to develop scuderi split engine. Since last 150 years no modification has been done for basic engine design. This scuderi split engine completely change the design structure of engine. CHAPTER 1 INTRODUCTION Project on EXPERIMENTAL SETUP FOR PERFORMANCE MEASUREMENT OF FOUR STROKE FOUR CYLINDER PETROL ENGINE DEVELOPEMENT OF SCUDERI SPLIT ENGINE consist of two stages. In first stage of the project, experimental setup for 4-cylinder petrol engine (Morse test) will be developed to determine the various engine performance parameters such as Break power, Indicated power, Friction power, Mass flow rate, Brake thermal efficiency, etc. The basic task in the design and development of engines is to reduce the cost of production and improve the efficiency and power output. In order to achieve the above task, the development engineer has to compare the engine developed with other engines in terms of its output and efficiency. Towards this end he has to test the engine and make measurements of relevant parameters that reflect the performance of the engine. For this the various test perform on engine are as follow: Willans line method Morse test Motoring test From the measurement of indicated and brake power Retardation test From this set-up of Morse test is simple and comparatively easy to conduct. Here, Rope brake dynamometer is used to measure power output. In second stage of project, the study of the scuderi split engine will be done comparison of it with conventional engine (4-S 4 Cylinder Petrol engine of Fiat Make). In conventional 4 Stroke engine, four strokes such as intake, compression, power exhaust performed in the single cylinder. While in scuderi split engine above Strokes performed in two cylinder which are connected using cross-over passage, in which pressure remains constant, in which two stroke intake compression take place in First cylinder, remaining stroke power exhaust take place in Second cylinder. CHAPTER 2 LITERATURE SURVEY 2.1 Introduction: The internal combustion engine is an engine in which combustion of fuel and an oxidizer (typically air) occurs in a confined space called a combustion chamber. This exothermic reaction creates gases at high temperature and pressure which are permitted to expand. The defining feature of an internal combustion engine is that useful work is performed by the expanding hot gases acting directly to cause movement of solid parts of the engine, by acting on pistons, rotors, or even by pressing on and moving the entire engine itself. The first internal combustion engines did not have compression, but run on air/fuel mixture sucked or blown in during the first part of the intake stroke. The most significant difference between modern internal combustion engines and the early designs was the use of compression and in particular of in-cylinder compression. 1876: Nikolaus Otto working with Gottlieb Daimler and Wilhelm Maybach had developed a practical four-stroke cycle (Otto cycle) engine. 2.2. Application of I.C. engine:- Internal combustion engines are most commonly used for mobile propulsion in automobiles, equipment, and other portable machinery. In mobile equipment internal combustion is advantageous, since it can provide high power to weight ratios together with excellent fuel energy-density. These engines have appeared in transport in almost all automobiles, trucks, motorcycles, boats, and in a wide variety of aircraft and locomotives, generally using petroleum (called All-Petroleum Internal Combustion Engine Vehicles or APICEVs) . Where very high power is required, such as jet aircraft, helicopters and large ships, they appear mostly in the form of turbines. 2.3. Classification of I.C.

The cylinders of multi-cylinder engine are cast as single unit, called cylinder block. The cylinder head mounted on the cylinder block .The cylinder head and cylinder block are provided with water jacket for cooling. 2.4.2 Cylinder:- As the name implies it is a cylindrical vessel or space in which the piston makes a reciprocating motion. The varying volume created in the cylinder during the operation of the engine is filled with the working fluid and subjected to different thermodynamics processes such as suction, compression, combustion, expansion and exhaust .The cylinder is supported in cylinder block. 2.4.3 Combustion chamber:- The space enclosed in the upper part of the cylinder, by the cylinder head and the piston top during the combustion process, is called the combustion chamber. 2.4.4. Piston: Piston is the heart of the engine. The functions of the piston are to compress the charge during the compression stroke and to transmit the gas force to the connecting rod and then to the crank during power stroke. The piston is a disc which reciprocates within cylinder. It is either moved by the fluid or it moves the fluid which enters the cylinder. The main function of the piston of an internal combustion engine is to receive the impulse from the expanding gas and to transmit the energy to the crankshaft through the connecting rod. The piston of internal combustion engines are usually of trunk type. This type of piston consists of different parts such as Head or Crown, Piston rings, Skirt, Piston pin etc. 2.4.5. Piston Ring: Piston rings provide a sliding seal between the outer edge of the piston and the inner edge of the cylinder. The rings serve two purposes: 1. They prevent the fuel/air mixture and exhaust in the combustion chamber from leaking into the sump during compression and combustion. 2. They keep oil in the sump from leaking into the combustion area, where it would be burned and lost. A piston ring is an open-ended ring that fits into a groove on the outer diameter of a piston in an internal combustion engine. The gap in the piston ring compresses to a few thousandths of an inch when inside the cylinder bore. 2.4.6 Inlet manifold:- The pipe which connects the intake system to the inlet valve of the engine and through which air or air-fuel mixture is drawn in to the cylinder is called inlet manifold. 2.4.7 Exhaust manifold:- The pipe which connects the exhaust system to the exhaust valve of the engine and through which the product of combustion escape in to the atmosphere is called the exhaust manifold. 2.4.8 Inlet and exhaust valve:- Valves are commonly mushroom shaped poppet type. They are provided either on the cylinder head or on the side of the cylinder for regulating the charge coming in to the cylinder (inlet valve) and for discharging the products of combustion from the cylinder (exhaust valve). 2.4.9. Connecting Rod: The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates. The small end attaches to the piston pin, gudgeon pin (the usual British term) or wrist pin, which is currently most often press fit into the con rod but can swivel in the piston, a floating wrist pin design. The big end connects to the bearing journal on the crank throw, running on replaceable bearing shells accessible via the con rod bolts which hold the bearing cap onto the big end; typically there is a pinhole bored through the bearing and the big end of the con rod so that pressurized lubricating motor oil squirts out onto the thrust side of the cylinder wall to lubricate the travel of the pistons and piston rings. 2.4.10. Spark Plug: The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must happen at just the right moment for things to work properly. 2.4.11. Crank shaft: The crankshaft turns the pistons up and down motion into circular motion just like a crank on a jack-in-the-box does. The crankshaft, sometimes casually abbreviated to crank, is the part of an engine which translates reciprocating linear piston motion into rotation. It typically connects to a flywheel, to reduce the pulsation characteristic of the four-stroke cycle, and sometimes a torsional or vibrational damper at the opposite end, to reduce the torsion vibrations often caused along the length of the crankshaft by the cylinders farthest from the output end acting on the torsional elasticity of the metal. 2.4.12. Cam shaft:- The camshaft and its associated parts control the opening and closing of the two valves. The associated parts are push rods, rocker arms, valve springs and tappets. This shaft also provides the drive to the ignition system. 2.4.13. Gudgeon pin: It forms the link between the small end of the connecting rod and the piston. 2.4.14. Cam:- These are made as integral parts of the camshaft and are designed in such way to open the valves at the correct timing and to keep them open for necessary duration. 2.4.15. Fly wheel: The net torque imparted to crankshaft during one complete cycle of operation of the engine fluctuates causing a change in the angular velocity of the shaft. In order to achieve a uniform torque an inertia mass in the form of a wheel attached to the output shaft and this wheel is called the flywheel. 2.4.16. Sump:- The sump surrounds the crankshaft. It contains some amount of oil, which collects in the bottom of the sump (the oil pan). 2.5. DIFFERENT TYPES OF MATERIAL USE FOR ENGINE PARTS:- 2.5.1. Cylinder liner: The cylinder liners are made in two types: wet liner dry liner. In case of wet liner, water in jacket is in direct contact with the outer wall of the liner; where as the dry liner is pressed into the cylinder proper. In engines over about 13cm bore; usually the wet type of liner is used. Liner materials: The liner material should be strong hard corrosion resistance. The following materials are used. 1. A good grade grey cast iron with homogenous and close grained structure i.e. prelatic and similar cast iron. 2. Nickel cast iron and nickel chromium cast iron 3. Nickel chromium cast steel with molybdenum in some case. 2.5.2. Material of cylinder head:- The cylinder head are usually made of close grained cast iron or alloy cast iron containing nickel, chromium and molybdenum, for small sized engine, while for large engine, the material is low Cast-steel. 2.5.3. Material used for piston piston ring:- Commonly used materials for piston of I.C. engine are cast iron, cast aluminum, cast steel forged steel. Generally cast steel is used for piston head. The material for the piston ring is cast iron alloy cast iron due to their good wearing qualities also they retain the spring characteristics even at high temperature. The material used for piston ring is nitrogen hardened or case hardened steel alloy containing nickel, chromium, molybdenum or vanadium. 2.5.4. Material used for connecting road:- The connecting rods of I.C.engine are mostly manufactured by drop forging. The material for connecting rod ranges from mild or medium carbon steel to alloy steels. In industrial engine, carbon steel with ultimate tensile strength ranging from 550-670Mpa is used. 2.5.5. Material used for crankshaft: The cylinder head are usually made of close grained cast iron or alloy cast iron containing nickel, chromium and molybdenum, for small sized engine, while for large engine, the material is low C-steel. Heavy duty cast iron, cast steel, nickel chromium steel is mainly used for manufacturing of crank shaft. 2.5.6. Material used for valves: Inlet valve run cooler than exhaust valves. So, the material for the inlet valves may be carbon steel, nickel steel, chrome nickel steel chrome molybdenum alloy, which may be hardened to withstand the repeated high stresses. Material for exhaust valves must be able to maintain their strength at high temperature. Therefore the material used for it is standard chrome nickel steel, cobalt nickel steel, high speed steel stainless steels. 2.6 NOMENCLATURE:- 2.6.1 Cylinder bore (d): The nominal inner diameter of the working cylinder is called the cylinder bore. It is expressed in millimeter (mm). 2.6.2 Piston area: The area of the circle of diameter equal to the cylinder bore is called the piston area. It is expressed by square centimeter (cm ²). 2.6.3 Stroke (L): The nominal distance through which a working piston moves between two successive reversals of its direction of motion is called the stroke is expressed in millimeter (mm). 2.6.4 Stroke to bore ratio: L/d ratio is an important parameter in classifying the size of the engine. If d If d=L, it is called square engine. If d>L, it is called over -square engine. An over square engine can operate at higher speeds because of large bore shorter stroke. 2.6.5 Dead center: The position of the working piston the moving parts which are mechanically connected to it, at the moment when the direction of the piston motion is reversed at either end of the stroke is called the dead center. There are two dead centers in the engine: Top dead center (TDC): It is the dead centers when the piston is farthest from the crankshaft. It is designated TDC for vertical engines inner dead center (IDC) for horizontal engines. Bottom dead center (BTC): It is the dead center when the piston is nearest to the crankshaft. It is designated as BDC for the vertical engines outer dead center (ODC) for horizontal engines. 2.6.6 Displacement or Swept volume: The nominal volume swept by the working piston when traveling from one dead center to other is called the displacement volume. It is expressed in terms of cubic centimeter (cc) given by VS = à Ã¢â€š ¬d ²L/4 2.6.7 Cubic Capacity of Engine Capacity: The displacement volume of a cylinder multiplied by number of cylinders in an engine capacity. For example, if there are K cylinders in an engine, then Cubic capacity = Vs x K 2.6.8 Clearance Volume (Vc): The nominal volume of the combustion chamber above the piston when it is at the top dead centre is the clearance volume. It is designated as Vc and expressed in cubic centimeter (cc). 2.6.9 Compression Ratio (r): it is the ratio of the total cylinder volume when the piston is at the bottom dead centre, Vt, to the clearance volume, Vc. It is designed by the letter r. r = Vt/Vc = (Vc + Vs)/Vc = 1 + Vs/Vc CHAPTER 3 WORKING OF AN I.C. ENGINE I.C. engine is a device which develops the work continuously taking the working fluid through cyclic process. The combination of piston and cylinder is suitable device for developing the work. In an arrangement of piston and cylinder of an ideal engine, following for process constitute the cycle: The air is compressed in the engine. Heat is added to the compressed air by external source. High pressure and high temperature air expands performing the work. The air after expansion returns to the original condition by rejecting heat to external sink. 3.1 The working principle of four-stroke spark ignition engine:- If an engine is to work successfully then it has to follow a cycle of operation in sequential manner. The sequence is quite rigid and can not be changed. In the following sections the working principle of both SI and CI engines is described. Even though both engines have much in common there are certain fundamental differences. The cycle of operation for an ideal four-stroke SI engine consist of the following four-stroke:- 1. Intake or suction stroke 2. Compression stroke 3. Power or expansion stroke 4. Exhaust stroke Intake or suction stroke :- Suction stroke starts when the piston is at the top dead centre and about to move downwards. The inlet valve is open at this time and exhaust valve is closed. Due to the suction created by the motion of the piston towards the bottom dead centre, the charge consisting of fuel-air mixture is drawn in to the cylinder. When the piston reaches the bottom dead centre the suction stroke ends and the inlet valve closes. compression stroke :- The charge taken in to the cylinder during the suction stroke is compressed by the return stroke of the piston. During this stroke both inlet and exhaust valves are in closed position. The mixture which fills the entire cylinder volume is now compressed in to the clearance volume. At the end of the compression stoke the mixture is ignited with the help of a spark plug located on the cylinder head. During the burning process the chemical energy of the fuel is converted in to heat energy producing temperature rise of about 2000 °C.The pressure at the end of the combustion process is considerably increased due to the heat release from the fuel. Expansion or power stroke :- The high pressure of the burnt gases forces the piston towards BDC. Both, the valves are in closed position .Of the four stroke only during this stroke power is produced. Both pressure and temperature decrease during expansion. Exhaust stroke :- At the end of the expansion stroke exhaust valve opens and inlet valve remains closed. The pressure falls to atmospheric level a part of the burnt gases escape. The piston starts moving from the bottom dead centre to top dead centre and sweeps the burnt gases out from the cylinder almost at atmospheric pressure. The exhaust valve closes when the piston reaches TDC .At the end of the exhaust stroke and some residual gases trapped in the clearance volume remain in the cylinder. CHAPTER 4 ACTUAL CYCLE FOR I.C.ENGINE DIFFERENCE BETWEEN ACTUAL CYCLE THERMODYNAMIC CYCLE:- The working substance is not air but a mixture of fuel and air during suction and compression and many gases during expansion and exhaust. Combustion of fuel not only adds the heat but changes the chemical composition also. The specific heat of gases changes with respect to temp. The residual gases change the composition, temp. and amount of fresh charge. The constant volume combustion is not possible. Compression and expansion are not isentropic. There is always some heat loss-due to heat transfer from the hot gases to cylinder walls. There is exhaust blow down loss due to early opening of exhaust valve. 4.2 VALVE TIMING DIAGRAM FOR 4-STROKE PETROL ENGINE:- (1) Inlet valve:- The intake valve should open, theoretically, at TDC; almost all SI engines an intake valve opening of a few degrees before TDC on the exhaust stroke. This is to ensure that the valve will be fully open and the fresh charge starts to flow into cylinder as soon as the piston reaches TDC. In figure ( ), the intake valve starts to open 10 o before TDC. As the piston descends on the intake stroke, the fresh charge is drawn in through the intake port and valve. It may be noted from figure ( ), that for a low speed engine, the intake valve closes 10o after BDC, and for a high speed engine, 60o after BDC. If the inlet valve is allowed to close at BDC, the cylinder would receive less charge than its capacity and the pressure of the charge at the end of the suction stroke will be below atmosphere. When the piston reaches BDC and start to ascend on the compression stroke, the inertia of the fresh charge tends to cause it to continue to move into the cylinder. At low engine speeds, the charge is moving into the cylinder relatively slowly, and its inertia is relatively low. If the intake valve were to remain open much beyond BDC, the up moving piston on the compression would tends to force some of the charge, already in the cylinder back into the intake manifold, with consequent reduction in volumetric efficiency. Hence, the intake valve is closed relatively early after BDC for a slow speed engine. For High Speed Engine, Inlet Valve closing is delayed after BDC to take above advantage. (2) Exhaust valve:- The exhaust valve usually opens before the piston reaches BDC on the expansion stroke. This reduces the work done by the expanding gases during power stroke, but decreases the work necessary to expel the burned products during exhaust stroke, and the result in an overall gain in output. During the exhaust stroke, the piston forces the burned gases out at high velocity. If the closing of the exhaust valve is delayed beyond TDC, the inertia of the exhaust gases tends to scavenge the cylinder better by carrying out greater mass of the gas left in the clearance volume, and result in increased volumetric efficiency. Consequently, the exhaust valve is often set to close a few degrees after TDC on the exhaust stroke, as indicated in figure ( ), it should be noted that it is quit possible for both the intake and exhaust valves to remain open, or partially open, at the same time. This is termed the valve overlap. (3) Ignition:- It would be proper to produce spark at the end of compression if the charge could burn instantaneously. How ever, there is always a time lag between the spark and ignition of the charge. The ignition starts some time after giving the spark, it is necessary to produce the spark before piston reaches the TDC to obtain proper combustion without losses. The angle through which the spark is given earlier is known as Ignition advance or Angle of advance 4.3 SOURCES OF LOSSES:- The difference between I.P. B.P. is known as total friction loss. This includes direct mechanical friction throttling losses through valves, pumping loss, blow down losses many others. 4.3.1. Direct frictional losses:- It includes bearing losses, as main bearing, camshaft bearing, and piston cylinder friction loss in many moving parts. The frictional losses are comparatively higher in reciprocating I.C. Engine. 4.3.2. Pumping losses:- The difference of work done in expelling the exhaust gases and the work done by fresh charge during the suction stroke is called the pumping work. In other words loss due to the gas exchange process (Pumping Loss) is due to pumping gas from lower inlet pressure to higher exhaust pressure. The pumping loss increases at part throttle because throttling reduces the suction pressure. Pumping loss increases with speed. The gas exchange processes affect the volumetric efficiency of the engine. 4.3.3. Blow by losses:- This loss because of leakage of combustion products past the piston forms the cylinder into the crank case. This loss depends upon inlet pressure and compression ratio .This loss increase directly with compression ratio but reduced with an increase in the engine speed. 4.3.4. Valve throttling losses:- The standard practice for sizing the exhaust valve is to produce smaller exhaust area than inlet valve area. This increases the pumping loss as smaller area resists more for the flow of exhaust gasses. This increase in speed of the engine rapidly if the valve size, valve timing and valve flow coefficients are not designed properly as shown in fig. by dotted line . The inlet throttling occurs due to the restrictions imposed by air cleaner, carburettor, and venture, throttle valve, inlet manifold and inlet valve. All these add in pressure loss .Similarly some pressure loss occurs during exhausting the burned gases. 4.3.5. Combustion chamber pump losses:- This loss occurs with pre-combustion chamber. This loss occurs due to the pumping work required to push the air into pre-combustion chamber through small orifice. This depends upon orifice size, and speed. It also increases with increasing the engine speed. 4.3.6. Power loss to drive the auxiliaries:- Some power is required to drive the auxiliaries such as water pump, fuel pump, cooling fan generator. This is also considered as loss as part of engine power developed is used for these purposes. 4.3.7. Heat loss factor:- During the combustion process and expansion the heat flows through the cylinder head. Some heat enters the piston and flows through the piston rings into the cylinder wall or is carried away by the engine lubricating oil which splashes on the underside of the piston. The heat loss along with other losses is shown on p-v diagram (Figure ( )). Heat loss during combustion has maximum effect on cycle efficiency while heat loss just before the end of expansion stroke has very little effect because of the contribution of useful work is very little. The heat lost during the combustion doesnt represent the complete loss only about 15% of total heat is lost during combustion expansion. If all the heat loss is recovered only 20% of if may appear as useful work. The effect of loss of heat during combustion is to reduce the maximum temperature and therefore, the specific heats are lower. Heat loss factor contributes around 12% to all their losses 4.3.8. Time loss factor:- In a thermodynamic cycle heat addition is assumed to be instantaneous process where as in actual cycle it is over a definite period of time .the time required for combustion is such that under all circumstances some change in volume takes place while it is in progress. The consequence of finite time of combustion is that peak pressure will not occur when volume is minimum i.e. when the piston at TDC but it will occur sometime after TDC. 4.3.9. Exhaust blow down:- The cylinder pressure at the end of exhaust stroke is about 7 bar depending on the compressor ratio. If the exhaust valve is opened at bottom dead centre the piston has to do work against high cylinder pressure during the part of the exhaust stroke. If the exhaust valve is opened too early, a part of the expansion stroke is lost. The best compromise is to open the exhaust valve 40 to 700 before BDC. Thereby, reducing the cylinder pressure to halfway to atmospheric before the exhaust stroke begins. 4.3.10. Knocking in SI- Engine:- Knocking is due to the auto-ignition of the end portion of the unburned charge in the combustion chamber. As the normal flame front proceeds across the chamber, the pressure the temp of the unburned charge increase due to compression by the burned portion of the charge. This unburned compressed charge may auto ignite under certain temp. Conditions release the energy at a very rapid rate compared to normal combustion process in the cylinder. This rapid release of energy during auto-ignition causes a high pressure differential in the c.c. and a high pressure wave is released from auto-ignition region. The motion of high pressure compression waves inside the cylinder causes vibration of the engine parts and pinking noise and it is known as knocking or detonation. Effect of knocking:- Mechanical damage:- Knocking creates very high pressure wave (200bar) of large amplitude. This increases the rate of wear almost of all mechanical parts like piston, cylinder head, valves. The frequency of this wave is as large as 5000 CPS. (2) Noise:- When the intensity of knock is high, a loud pulsating noise is created because of high intensity pressure wave vibrates back and forth across the cylinder. This noise is like as bell noise. (3) Increase in heat transfer rate:- When the engine is knocking, more heat is lost to the coolant as the dissipating rate increases. The major reason of increases in heat transfer rate during knocking is, the boundary layer of the gas near the wall is removed because of high vibration of gas molecules. (4) Power output:- It is also observed that slightly rated spark develops more power under knocking condition. This may be due to rapid burning of the last part of the charge and retard spark may be optimum under knocking. (5) Pre ignition:- It defined as an ignition of the charge as it comes in contact with hot surface, in the absence of spark. Auto ignition may overheat the spark plug and exhaust valve and it remains so hot that its temp. is sufficient to ignite the charge in the next cycle during the compression stroke before the spark occurs an this causes the pre ignition of the charge. The temperature required for pre i

The main symptom of osteoarthritis is sharp pain, or a burning sensation in the associate muscles and tendons, causing stiffness and loss of ability. OA can cause a crackling noise or crepitus when the affected joint is moved, and the patient may experience muscle spasm and contractions in the tendons. Occasionally, the joints may also be filled with fluid. Humid and cold weather increases the pain in many patients. OA commonly affects the hands, feet, spine, and the large weight bearing joints, such as the hips and knees, although in theory, any joint in the body can be affected. As OA advances, the affected joints appear larger, are stiff and painful, and usually feel worse, the more they are used throughout the day, thus distinguishing it from rheumatoid arthritis. In smaller joints, such as at the fingers, hard bony enlargements may form, and though they are not necessarily painful, they limit the movement of the fingers significantly. OA at the toes leads to the formation of bunions, rendering them red or swollen. OA is the most common cause of joint effusion, an accumulation of excess fluid in or around the knee joint (Moskowitz, 2007).

Her cause of dementia is Alzheimer’s disease. This condition frequently begins with memory loss or subtle impairments in other cognitive functions. These changes might initially manifest as simple forgetfulness or absentmindedness or as minor problems with language, judgment, or perception. As dementia progresses, memory loss and cognitive impairment extend in scope until the person can no longer remember basic social and survival skills or function independently. Language, spatial or temporal orientation, judgment, perception, and other cognitive capacities decline, and personality changes may occur (Bourgeois Hickey, 2011). She suffers from hypertension whose symptoms include: Blood in the urine Severe headache Vision problems Fatigue or confusion Chest pain Difficulty breathing Irregular heartbeat Pounding in the chest, neck, or ears (Izzo Black, 2003). Urinary tract infections (UTI) do not always cause signs and symptoms, but they can include: A strong, persistent urge to urinate A burning sensation when urinating Passing frequent, small amounts of urine Urine that appears cloudy Urine that appears red, or bright pink colored, which is a sign of blood in the urine Strong-smelling urine Pelvic pain in women (Kilmartin, 2002) Heart: Normal in size.

Therefore, she fits in the 8th Psychosocial Stage of Integrity vs. Despair. The patient is now a senior citizen. She tends to slow down on productivity, and explore life as a retired person. It is during this time that she contemplates her accomplishments and is able to develop integrity if she sees herself as leading a successful life. If she sees her life as unproductive, feel guilt about her past, or feel that she did not accomplish her life goals, she will become dissatisfied with life and develop despair, often leading to depression and hopelessness. Success in this stage will lead to the virtue of wisdom. Wisdom will enable her to look back on her life with a sense of closure and completeness, and also accept death without fear. (Shaffer, 2008) The patient lives with her son who takes care of her medical and financial needs. The patient has a decreased cognitive ability and is not able to safely take medication by herself. She experiences a high level of insomnia/sleep deprivation. She also suffers from depression exacerbated by a lack of self-efficacy.

Exercise could increase her endurance and strengthen the muscles around her joints, making her joint more stable. She can try walking, but she should stop if she feels new joint pain. New pain that lasts for hours after she has exercised probably means she has overdone it, but does not mean she should stop exercising altogether. Using hydrotherapy, local heat and cold to manage pain: Both heat and cold can relieve pain in her joints. Heat also relieves stiffness, and cold can relieve muscle spasms and pain. Applying over-the-counter pain gels/creams. Creams and gels available at drugstores might offer temporary relief from osteoarthritis pain. Some creams numb the pain by generating a hot or cool sensation whereas other creams have medications, such as aspirin-like compounds, that get absorbed into the skin. Pain creams would work best on joints that are close to the surface of her skin, such as knees and fingers. Using assistive devices. Assistive devices could make it easier for her to go about her day without stressing the painful joints. A cane might take weight off her knees or hips as she walks. Weight management. Being overweight can increases the stress on her weight-bearing joints, such as her knees and hips. Therefore, the patient should maintain her weight to prevent putting pressure on her joints, which could increase her pain. 1/27/15HPN 4oz TID with meals for supplement 7/20/14 Regular diet 1/26/15 Ice cream at HS 9/16/14 4.1.1 benign hypertension.

Influential Essay :: essays papers

Influential Essay A lot of people take their driver’s license for granted, and believe me I use to take it for granted too. But ever since I lost my license, I will never take it for granted again. There are many ways to lose your license, but this is the way I lost mine. After I got done listening to music at the Concert Cafà ©, my friends and I went out to eat. When we were done eating, I told them I was going to head back home. They told me that they were going to stay in town for awhile. So, when I was about three quarters of the way home, all of the sudden a car just passed me. I noticed the car right away, it was my friends that said they were going to stay in town for awhile. So I caught up to them and we were going about 55 mph in a 35 mph speed limit. When my friends approached another car they passed him so I did the same. Now we were going about 65 mph in a 45 mph speed limit. My friends kept accelerating so I thought to myself, â€Å"How am I going to get pulled over if I am following another car?† After our speed finally settled at around 80 mph we were still in the 45 mph speed limit. About four miles later when were still cruising at 80 mph, but n ow in a 55 mph speed limit I saw red and blue lights in my rearview mirror. So, I pulled over and so did my friends. When the cop approached us he pulled ahead of me, but behind my friends. I thought to myself, â€Å"All right, I got away.† So I pulled back out on to the road, but the cop didn’t move out of the lane. Then I pulled back onto the shoulder of the road and the cop nestled his way in between my friends and myself. We both ended up getting a ticket for going 79 mph in a 55 mph speed limit. We both got a ticket for $172.90 and six points on our license. When I got my second ticker I was dropping off a letter to my priest and I was on my way home.

Internship with the Police Department Essay -- Internship Police Depar

Internship with the Police Department Throughout my one hundred and twenty-hour experience with the Gloversville Police Department, I learned many skills, values and the ways of this Police Department. Many of the calls and situations I went to often could relate to a certain theory that I learned in any of my law classes. I would recommend any student majoring in Criminal Justice to try to take an internship with a local law enforcement agency. I am currently signed up for the civil service test for Gloversville Police Department, If I do qualify for the Police I believe that this internship will give me a huge head start. Some experiences that I encountered were DWI'S, Assaults, Traffic Tickets, Domestic Disputes, and going into the bars for ABC checks. The best Dwi I saw was when we pulled over a twenty-nine year old Marine. The officer that I was with wanted to let him go but couldn't because of the condition of the offender. So we cuffed him and brought him to the station. While filling out the report for him we get a call about a kid who was struck at a bar by another man. We asked if he wanted to press charges and he replied with a yes. We went to his house and found out it was a twenty-five year-old who was majoring to be a lawyer. The officer I was with that night knew this kid and thought very low of him because of past incidents. Come to find out the twenty-nine year old we had in custody was the one that had assaulted him earlier in the bar. We told him to come down in the morning and sign to press charges. When we got back to the station the Officer I was with asked him why he didn?t hit hi m harder. It was way to make him laugh and relax. After that we all got talking and it actually did calm him down and I learned that even though someone committed a crime that it doesn?t necessarily mean that person is a bad person. When dealing with assaults I learned that no matter how much you agree with a person or want to believe a person that you cant take sides. To me this was one of the major lessons that I learned in this program. We were dispatched to a call at the Caboose for a fight. When we arrived I saw two younger males and an older male fighting. Immediately I thought that the two younger males were drinking and started a fight with this older man who was walking down the street. To my mistake we found out that the two men were helpi... ... that will hopefully improve my handwriting skills. Besides the writing I feel that most of my skills are good. If I become an Officer myself I believe that these would only improve. If I were to be grading myself on this internship program I would give myself a B. I believe that I would deserve an A but this paper itself is not the certain length required. Through the program I learned a lot of valuable information about police departments themselves and how they work because I was actually there. No teacher could have taught this to any students, its something that they would have to experience themselves and something that I highly recommend to any student who is serious about taking criminal justice. The internship program was one of my best experiences with college. I learned a lot of information dealing with the Police and how they work. I also learned that I want a career in this field. I want a job that is different everyday and I don?t know what?s going to happen day after day. Thank you for creating the opportunity for me to experience what it?s like in a Police Department. I greatly appreciate all the time and effort you put forward for me to do this internship.

Authority Power Politics

Authority/Power/Politics Authority What is Authority The word authority derives from the Latin word auctoritas meaning invention, advice, opinion, influence or commands which originate from an auctor, indicating that authority originates from a master, leader or author. Essentially authority is imposed by superiors upon inferiors either by force of arms (structural authority) or by force of argument (sapiential authority). Usually authority has components of both compulsion and persuasion. For this reason, as used in Roman law authority is differentiated into potestas (legal or military power) and imperium (persuasive political rank or standing). Weber on Authority Max Weber in his sociological work has identified and distinguished three types of authority. Weber defined authority as the chance of commands being obeyed by a specifiable group of people. Legitimate authority is that which is recognized as legitimate and justified by both the ruler and the ruled. Weber divided legitimate authority into three types: The first type discussed by Weber is Rational-legal authority. It is that form of authority which depends for its legitimacy on formal rules and established laws of the state, which are usually written down and are often very complex. The power of the rational legal authority is mentioned in the constitution. Modern societies depend on legal-rational authority. Government officials are the best example of this form of authority, which is prevalent all over the world. The second type of authority is Traditional authority, which derives from long-established customs, habits and social structures. When power passes from one generation to another, then it is known as traditional authority. The right of hereditary monarchs to rule furnishes an obvious example. The Tudor dynasty in England and the ruling families of Mewar, in Rajasthan (India) are some examples of traditional authority. The third form of authority is Charismatic authority. Here, the charisma of the individual or the leader plays an important role. Charismatic authority is that authority which is derived from â€Å"the gift of grace† or when the leader claims that his authority is derived from a â€Å"higher power† (e. . God or natural law or rights) or â€Å"inspiration†, that is superior to both the validity of traditional and rational-legal authority and followers accept this and are willing to follow this higher or inspired authority, in the place of the authority that they have hitherto been following. Some of the most prominent examples of charismatic authority can be politicians or lead ers, who come from a movie or entertainment background. These people become successful, because they use their grace and charm to get more votes during elections. Examples in this regard can be NT Rama Rao, a matinee idol, who went on to become one of the most powerful Chief Ministers of Andhra Pradesh. History has witnessed several social movements or revolutions, against a system of traditional or legal-rational authority, which are usually started by Charismatic authorities. What distinguishes authority, from coercion, force and power on the one hand and leadership, persuasion and influence on the other hand, is legitimacy. Superiors feel that they have a right to issue commands; subordinates perceive an obligation to obey. Social scientists agree that authority is but one of several resources available, to incumbents in formal positions. For example, a Head of State is dependent upon a similar nesting of authority. His legitimacy must be acknowledged, not just by citizens, but by those who control other valued resources: his immediate staff, his cabinet, military leaders and in the long run, the administration and political apparatus of the entire society. Power What is Power Power is a measure of an entity's ability to control the environment around itself, including the behavior of other entities. The term authority is often used for power, perceived as legitimate by the social structure. Power can be seen as evil or unjust, but the exercise of power is accepted as endemic to humans as social beings. Often, the study of power in a society is referred to as politics. Sources of Power Power may be held through: Delegated authority (for example in the democratic process) Social class (material wealth can equal power) Personal or group charisma Ascribed power (acting on perceived or assumed abilities, whether these bear testing or not) Expertise (Ability, Skills) Persuasion (direct, indirect, or subliminal) Knowledge (granted or withheld, shared or kept secret) Celebrity Force (violence, military might, coercion). Moral persuasion (including religion) Operation of group dynamics (such as public relations) Social influence of tradition (compare ascribed power) In relationships; domination/submissiveness Politics What is Politics Politics is a process by which groups of people make collective decisions. The term is generally applied to behavior within civil governments, but politics has been observed in other group interactions, including corporate, academic, and religious institutions. It consists of â€Å"social relations involving authority or power† and refers to the regulation of a political unit, and to the methods and tactics used to formulate and apply policy. Politics at Workplace Politics – the other face of the creative, innovative and manipulative and human mind, which always seeks power, recognition and authority. So how can there be no politics at the place where hundreds and thousands of human minds are spending most part of their day and there’s a constant struggle for power and recognition. Yes, double standards, secrecy, camps, demoting others and/or self promotion, in short – politics is all over the workplace. No organisation is and will be completely free from the politics. Office politics refers to the use and manipulation of situations, power and people to secure their position, gain from the situation, let others down or even increase their own power, image and status within the organisation. The results or the benefits can be tangible or intangible, depending upon the situation. Politics at workplace is a game can be played equally well by a single player or teams together, can result in the interest and benefit of the organisation or go against it, can benefit those who don’t play or can throw them out of the organisation. It is a double edged sword which can either create a happy, dynamic and improved environment at the workplace or can destroy it. Politics at workplace is often hard to resist and be away from. It compels and makes you compete. Although a part of all the organisations across the world, the politics at workplace has taken the more advanced and dangerous form in India, where the people staying away from it are being seen as a threat. Office politics has made employees good actors, hiding the facts and even true self from their own colleagues and organisation and being hypocrites for their reasons. Grey side of the issue Every workplace has conflicts, but how the employees and the organisation tackle it goes a long way in ensuring the success of the employees as well as the organisation. Politics at workplace is complex, and can turn the organisation into an ugly and nasty battlefield. Most often, the power is the bone of contention. The powerful employee can take advantage of the situations and manipulate things. The employees can take the things to them at a personal level. This, in turn, can harm their personal and professional lives. Playing on other people’s emotions to make things work for them, people have stooped to such levels where they have put their own morals and conscious aside. But the organisation feels the brunt of the continuous politics at workplace when it starts effecting the overall performance, efficiency and productivity of the organisation. This is mainly due to the considerable amount of time spent on the politics and thinking about the strategies and the moves, rather than the job and the work. Ultimately, this can lead to losses for the organisation and even the loss of jobs for the employees. Workplace Politics: A necessary evil Again, the question arises about the employees who do not become a part to this politics at their workplace. Experts say that giving up to the politics without being a part of it and fighting it, especially when it is unfair, is not advisable either. Sometimes, the politics becomes the necessary evil simply for self defense. As often, the people staying away are taken as a threat and become the victim of the workplace politics and are eliminated. As it has become unavoidable to avoid the politics at today’s workplace, it has become necessary for every employee to: connect to people, try to identify the source of power, bserve and be aware of the happenings around, people’s strengths and weaknesses and their emotional intelligence. Avoiding politics at workplace Although it is practically impossible to make your workplace free from the politics, but the organisation and the employees can follow certain ethics for themselves to make their workplace healthier: Avoid distor ting or manipulating the truth and the facts. Be yourself. Don’t have different faces to suit different people and different situations. Be fair in your dealings. Take decisions based on other’s performance and not on the basis of your relations with them. Be flexible, approachable and accessible to others. Rigidity can isolate you. Communicate – Lack of proper communication is the root cause of most of the problems. Therefore, ensure a timely and open communication system. Hiding information, rumors or distorted information can aggravate the situation and problem. Proper communication will also help to combat the effect of gossip. Have a broader perspective. Don’t work to satisfy your ego every time. Give a fair chance to everyone to put forward their thoughts. Last but not the least; be clear in your conscious. Don’t compromise on your morals and ethics and, don’t hesitate to apologize if you realize that you are wrong. It would be right to conclude that being a part of the interpersonal relations, politics at workplace is prevalent everywhere, and is unavoidable in most cases. But it’s more important to play the game right. Know the rules, stay true to yourself, don’t harm someone personally or his/her career, don’t take grudges home. Try to create a win-win situation for yourself, others and the organisation. Politics at workplace – can be good or bad – depends on how people take it and make it! Don't confuse authority, power, and politics If you work in an organization, you need a clear understanding of three closely related concepts–authority, power, and politics. Unfortunately, for many employees these concepts often confuse, frustrate, or elicit anxiety or indifference. The traditional concept of organization is built upon the principle that someone has the â€Å"right† to command someone else, whose duty is to obey the command. This â€Å"right† is bestowed by the formal organization, and we call it authority. It is important to note that â€Å"right to command† does not connote the â€Å"capacity to command. Most of us would be making a mistake if we were to equate right and capacity–i. e. , authority and power. This is especially true in a professional environment. We must always be careful to undergird our right to command with the appropriate power, the capability to secure dominance of one's values or goals, if we want to develop and maintain highly effective organizations. Even though it may be socially unacceptable to admit that one aspires to power or worries about power relationships, we must recognize that power and politics enter into every organizational decision. Positive power. However, concern about power and politics does not mean that a person is committed to such Machiavellian tactics as â€Å"doing unto others before they do unto you. † Power has a positive side as well. Organizations could not function without some kind of power relationships. The positive side is characterized by a concern for group goals and their achievement. Leaders enjoy the greatest overall influence when they help their followers feel powerful and accomplish greatness on their own. The direction of communications, their frequency, and their content reveals a great deal about the power relationships within an organization. It is as simple as who talks to whom about what. Office politics. The process by which power is exercised and sometimes acquired is called politics. In politics, contesting forces compete for favorable outcomes on decisions involving who gets what and how. Political activity is usually stronger where there are no prescribed routine answers or no stated policy. It also centers around the interpretation of existing policies and those situations involving value judgments. Any organization that attempts to totally reduce these arenas of political activity by instituting rules, regulations, and policies from the top would quickly strangle in its own red tape. Political processes form the dynamic that enables the formal organization to function. In a sense, power and politics act as the lubricant that enables the interdependent parts of the organization to operate smoothly together. When we pretend that power and politics don't exist, we greatly reduce the ability of an organization to get things done, especially when innovation and change are involved, because they abandon procedures we have always followed. Since power and political processes are a fact of life in all organizations, we must develop and use the appropriate skills to achieve the organization's goals. Managers must avoid working in isolation and instead as part of the flow of social forces. They must understand that a managerial position is not self-perpetuating.
