Can Britains political system continue mostly unchanged given its European Union Membership

Can Britains political system continue mostly unchanged given its European Union Membership Introduction Unlike many other nations of the world, Britain does not have a written constitution. A written constitution consists of all the laws and by-laws of a country that have been written down and explained in details. In a written constitution, every law that governs a particular nation is usually contained therein. A written constitution therefore consists of one large document, containing all the laws of a country.Advertising We will write a custom research paper sample on Can Britain’s political system continue mostly unchanged given its European Union Membership? specifically for you for only $16.05 $11/page Learn More However, the British constitution is not contained in a documented book, but the different rules and laws governing the country are contained in different documents. Some of the laws are not even contained in any document, but nonetheless, they exist and are in use (Jones, 2009). The British government exercises full parliam entary sovereignty, whereby the parliament is able to pass all the laws of the country. In addition, parliament has the final word on most matters concerning the nation. The British governance is thus dependent on the customs and traditions of the nation. Just as many other nations have rules that have to be followed by members of the society, albeit informally, the British government also works in a similar manner. In 1970, Britain joined the European Union and the question that now arises is whether the British government will have to change its mode of governance in order to fulfill the demands of the European Union (Jones, 2009). The most evident structure of the British government is the parliament. Parliament exercises full supremacy in the nation. In all the undertakings of the British government, the final decision rests with the parliament. The British parliament is built around democratic governance and this ensures that all its actions are directed towards democratic gove rnance. On many occasions, it has become necessary to change issues that harm or affect people negatively. On the other hand, if something does not seem to have any harmful effect, I do not think it would be of any use trying to change it (Jones, 2009). The unwritten constitution The nature of Britain’s unwritten constitution seems to be the best thing for the entire British kingdom. This is because British laws are not constant but dynamic. For this reason, I am obliged to support the idea that Britain should continue with its current mode of governance, whereby use is made of the unwritten constitution even though the country is now affiliated with the European Union (Jones, 2009).Advertising Looking for research paper on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More The rules and regulations governing Britain can always be changed to suit any situation that arises. For example, changes in the economy can easi ly be incorporated by changing the laws of the nation. This is one of the strong points that have enabled Britain to be on the forefront in matters concerning the economy. In a written constitution, any changes in the economy of a particular nation cannot be incorporated into the nation immediately they occur. This is because doing so would be against the written law and hence, illegal. It would take some time for such changes to occur because the constitution would have to be changed as well. By the time the constitution is changed, sometimes the intended changes may no longer have a positive impact on the people, unless the intended effect is long-term. Among the countries with a written constitution, the courts have the power to strike down the judiciary of the country. However, this is not the case with Britain since, it is only parliament that has the legal supremacy over all the other sections of the nation (Jones, 2009). This does not give the courts the authority to strike d own any of the actions of the parliament. Sometimes, the actions of the courts are not usually up to standard since they must adhere to the written laws and regulations. As such, they do not take into account the benefits of a given situation at present or in the future. This brings in the issue of legal and non legal rules (Jones, 2009). All the laws contained in a written constitution are the legal regulations that should be followed at all times. This rule out the possibility of having to do something that is against the constitution, even though it may not be harmful. In Britain, both the legal and non-legal rules are contained in the constitution. The non-legal rules constitute a significant part of the constitution. These are referred to as conventions. The conventions are also flexible, in that they can be changed when need arises, unlike the written laws. However, not everybody is entitled to such conventions at all times. One can fail to adhere to a particular convention at a particular time when they feel that it is the best thing to do. This cannot be termed as illegal or against the law since conventions are not there to be followed at all times. This is unlike in the written constitutions where there are no legal and non-legal rules. All the laws are classified as legal and anybody who goes against these written laws is deemed to have defied the constitution. Consequently, such a person may be prosecuted in a court of law. In conventions, the court does not have any power over their influence (Politics Association, 1988).Advertising We will write a custom research paper sample on Can Britain’s political system continue mostly unchanged given its European Union Membership? specifically for you for only $16.05 $11/page Learn More Considering that the British government has been operating under an unwritten constitution and that no major chaos has arisen due to this form of governance, it would really be hard for the people to understand the need to change from an unwritten to a written constitution. Since Britain is now operating under a coalition government that is required to conform to the laws set by the European Union, this does not necessarily mean that Britain has to adopt a written constitution (Jones, 2009). The best thing that needs to be done is to for Britain to adhere to the laws laid down by the European Union. Whether the European Union laws are incorporated into Britain’s constitution in written form or unwritten, the most important thing is to acknowledge their presence and abide by them. If Britain’s constitution is changed from unwritten to written, it may bring about some adverse effects. The people are already used to the unwritten constitution and most of them are aware of the laws and regulations that govern the nation. With the adoption of a written constitution, the flexibility of laws would be cut short and it would be hard for the nation to catch up with the changing dynamics of the economy (Jones, 2009). Human Rights Act The European Union contains many written and well explained laws. The fact that they are written does not mean that everyone in any country under the European Union is fully conversant with each and every law. Only a few people could be fully aware of such laws. Thus, the best thing is to be aware of the existence of the laws and to follow them to the best of your capability. A major problem that seems to arise is whether British courts can acquire the power that the Human Rights Acts enforced by the European Union offers (Jones, 2009). Again, the Human Rights Act encourages cooperation between the legislature and the judiciary of a nation but the final say is always reserved to the parliament. This shows that although courts in Britain may end up acquiring some more power as a result of the Human Rights Act, the parliament can still retain its role as the final decision maker of the nation.Advertising Looking for research paper on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More This shows that no major changes need to be effected in the British government as a result of the Human Rights Act being in operation. British can still retain the supremacy of the parliament because, the main theme of the parliament’s actions are to the benefit and welfare of all the nation’s citizens (Politics Association, 1988). Conclusion In conclusion, the British government does not necessarily have to change the laws of its nation for having joined the European Union. What needs to be done is to enforce the laws that have been outlined by the European Union. These can be exercised alongside the laws of the nation. At the national level, Britain can continue with its operations as before but when it comes to matters concerning the coalition government, Britain is bound to follow the laws outlined by the European Union. Parliamentary supremacy has been the mode of governance and it can still continue to be, with only a few changes occurring to the courts, since, d ue to the Human Rights Act, they are bound to acquire some more power than before (Jones, 2009).

Comparison between Bahraini and Swiss Civil Law Essay

Comparison between Bahraini and Swiss Civil Law - Essay Example Bahrain has sufficient exposure to the British legal system, and its legal system is mixed drawing from both codified systems; Islamic law and English common law (Bahrain Civil Code, art. 1). Bahrain became a British protectorate in 1880 after the Ottoman Empire lost control over it in 1861. In August 1971, Bahrain gained full independence from its British protectorate. It formed a legislative committee to establish a legal system that was independently appointed upon independence. Egyptian codes and the law similar to Arab states, therefore followed from that day. It is unlike the Swiss civil law that is not exposed to the British legal system (Swiss Civil Code, art. 1). The Swiss civil codified law ruling in Switzerland and regulating relationships between individuals includes; French; Code Civil, Italian; Codice civil, Germany; Zivigesetbuch, Roman; Cudesch civil and finally Turkish; Media. The Swiss civil code of 10the December of 1907, it became in force in 1912. Another similar ity is that both civil laws coded. It makes it easier to trace any law since it is in one booklet for the purposes and reference of the civilians. Another difference comes in the form. In Bahraini civil law, certain procedures or acts may be required to be effected in a certain specific form, if this not followed, the procedure or act may be considered as invalid. Article 72 of the Bahraini Evidence Law states that every verdict that orders the evidence given by the witness shall indicate all facts that are ordered to prove.

New Kind of e-Business Essay Example | Topics and Well Written Essays - 2000 words

New Kind of e-Business - Essay Example 2 Nature and Purpose of Business The nature of this business will be to go beyond dog training. Many people have dog trainers or have experience them and they teach everything from traditional training to Cesar Mellan techniques. However, there are no DVDs that go beyond this typical training to doing creative calisthenics with the dogs. The purpose of the business would be to keep dogs fit without having to walk them everyday or run them everyday. Just as humans become bored with routine, the DVDs would insure that dogs not only were exercised, but they would be exercised in a creative way. The individual pet owner could do these simple calisthenics with their jobs or they could hire a certified trainer in this method to come to their home and give the dog a workout. Many people hire dog trainers and they expect their dogs’ behavior to improve through training. Often this helps, but there are dogs with so much energy that they need to have more than one way to expend this ene rgy. According to Liz Palika, author, there are many benefits of training your dog. Some of these benefits include: a better behaved dog, bonding between human and dog, it can be fun for both the human and the dog (especially if the dog learns how to do tricks). Although Palika talks about traditional dog training, these same benefits can be used to help people understand how to do doggie calisthenics. 2.1 Why Doggie Calisthenics The word calisthenics means to do small exercises that are geared to develop muscle tone and overall physical well-being. When this definition is applied to dogs, it means creating interesting small exercises that will help to increase the dog’s overall health. Obviously many people use running and walking their pets as the way to keep them healthy, but dogs need other types of exercise to insure they are keeping muscle tone and not turning into those pudgy animals that begin to have health problems. Doggie callisthenic DVDs would be perfect for high energy dogs and small toy breeds that have lots of energy. Some examples of these exercises are playing fetch, cycling with your dog (although the dog must be well trained as well), gym workouts (with treadmill or obstacle courses in a gym), or stair climbing. All of these are examples of calisthenics that are easy to do and that can be done with anyone. Of course, all pet owners should have their dog checked at the vet before starting any exercise program. Doggie calisthenics would not be done to take the place of walking or running, but they would be used in addition to these other methods of training. They would be used as a warm up exercise or they could be used when the individual pet owner was not able to get their dog outside for a walk or a run. The DVDs would promote a 10-15 minute workout which could be done along with the pet owner’s workout. The DVDs would show step-by-step how to get the dog interested in the exercise, how to monitor their heart and pulse and it would provide safety tips to show how easy it is to keep a dog healthy and make sure they are fit. There would also be a list of dog breeds that came with the package that would tell which dogs were more prone to need more exercise. 3 Competitive Advantage There are several competitive advantages that this business would have as an e-business. The pet owner would be able to either purchase DVDs or the various programs or they would be able to

Mother Tongue Essay Example for Free

Mother Tongue Essay Today we live in a society that is often called a salad bowl. It is called a salad bowl because it consists of various different people from various different backgrounds. We all live together in a society, but we still retain our own distinct flavors which helps to contribute to the richness and diversity of society. Unfortunately, today we also live in a society in which some of these groups are marginalized and looked down upon by others. Hence, often times as individuals we feel the need to compromise the way in which we communicate our ideas so that we can appeal to the views of the majority. Two authors explore how their attempt to compromise almost caused them to become detached from their roots. In Mother Tongue, by Amy Tan, Tan talks about growing up as a young child in America and learning the English language. She speaks about growing up as a writer and her mothers imperfect diction which had a major influence on her. On the other hand, In her essay, Censoring Myself, Betty Shamieh talks about being an American playwright and having to censor herself because of how her work was viewed. Both authors explore the influence that their background had on their ability to express themselves. As individuals we should not be afraid to express ourselves because of our differences, rather we should use our differences and show how our distinctions make us very unique. Firstly, In Mother Tongue, Tan talks about how her mothers limited English diction skewered her perception of her mother. Tan mentions how, Like others, I have described it to people as broken or fractured English (Tan 273). This shows how Tan viewed her mothers English speaking abilities. She describes it as if her mother spoke damaged English, which needed to be mended or repaired. For Tan it was imperative that she spoke proper English and used proper diction, thus she was ashamed of her mothers English. Tan fell under the impression that her mothers English speaking abilities reflected the quality of what she had to say. Since her mother expressed her words in an imperfect manner, tan believed that her thoughts were also imperfect (Tan 274). Her perception was also supported by how people in society responded to her mother. Tan states that people in  department stores, banks, and restaurants would not take her mother seriously. They would provide her bad service, pretend not to understand her, or act as if they were mute (Tan 274). This further contributed to Tans feeling of embarrassment and shame towards her mother. Tan also describes an incident in which her mother went to the hospital and was told that the hospital had misplaced her CAT scan. The hospital did not show any remorse for losing the scan, nor did they assure her that they would locate it, that is until her mother had Tan speak to the hospital (Tan 275). As a reader this shows us how language is perceived and the role that it plays in the lives of individuals. For Tan it was imperative that she was able to blend in and be like others, so that she wouldnt be ridiculed. Luckily, she was able to realize the positive influence that her mothers diction bought her. Furthermore, Tans mother teaches her to think in a different manner than the other children in her school. Tan states that her developing language skills were influenced by her family and in this case her mother, hence it affected her results on achievement tests. Since her mother taught her to think differently she was unable to perform as well in English as she did in math and science. Later Tan realizes the value of this different systematic way of thinking and it contributes to her rebellious nature towards her teachers who suggested shed be much better in engineering, accounting, or anything else than English, since she was of Asian descent. She decided to challenge this stereotype, and thanks to her mother became a writer, who didnt write using challenging diction that required a lot of thought, but rather diction that could be read and understood by audiences such as her mother. This is the reason she starts writing about her mother: â€Å"I wanted to capture what language ability tests can never reveal: her intent, her passion, her imagery, the rhythms of her speech, and the nature of her thoughts† (Tan 277). She acknowledged the richness that her mothers heritage provided her and then she decided her first reader and critic should be her mother. Overall this taught Tan that she didnt need to compromise to the high caliber and complexity of the English language, but rather she could express her thoughts in a simplistic, yet effective way which could be understood by everyone. In her essay, Censoring Myself, Betty Shamieh talks about being an American playwright and having to censor herself because of how her work was viewed by others. She states: I have been censored in many ways. But I think the most overt example of censorship I have yet faced is my experience with a project called the Brave New World Festival (Shamieh 294). For the Festival she wrote a monologue about being the sister of a suicide bomber in mourning because she was unable to prevent his vicious act of terrorism. Her approach towards writing this play was to promote anti-terrorism, but due to the harsh tragedy of 9/11 she felt that there would be some potential backlash. When she was asked to perform her monologue at the Brave New World Festival, she was very skeptical of being criticized, thus she asked a famous actress named Marisa Tomei to act in the play (Shamieh 295). Post 9/11, president Bush let it be known on national television that he thinks citizens better watch what they say (Shamieh 294). This shows the amount of tolerance that was granted towards individual expression post 9/11, where anything that was said could be viewed in light of terrorism. As an Arab American Shamieh acknowledged that her work would be a source of criticism, but she felt the need to express her view and in doing so had to compromise so that she could get her play preformed. Moreover, Shamiehs play was ridiculed for its content, so being afraid of losing her spot in the festival she produced another piece that could be preformed. This shows the censorship she faced with her work and her need to compromise her writing so that it would appeal to the majority. Shamieh states that: Arab American artist are largely faceless in this country and I felt that, by dropping out, I would be helping those who are trying to keep it that way (Shamieh 295). This portrays Shamiehs want to express her views and to represent the Arab community, whos voices were neglected. Essentially she was trying to give a voice to the voice less. She later presents a story about an Arab-American girl who ends up on a hijacked plane and talks the hijackers out of their plans. Once again her intent was to promote anti-racism, but in a humorous way, yet her new play was not only censored, but this time completely taken out of the festival. This shows the ability individuals had in being ab le to express their ideas. Being an  Arab American, Shamieh had the right to express her views, yet despite this, her work was viewed under a wrong light and taken out of the play. This taught Shamieh that as individuals we will often face censorship for many reasons, whether it may because of our race, ethnicity, gender, sex, etc. For Shamieh, this experience taught her to write about the things she cared about, the things that represented who she was. She acknowledged that she was censoring herself by not producing a play about the Palestinian experience, which was a huge part of who she was (Shamieh 296). As individuals we will often face criticism from others, but the important thing is to express our voices so that we can communicate our ideas and portray ourselves under a proper light. Hence, often times as individuals we feel the need to compromise the way in which we communicate our ideas so that we can appeal to the views of the majority. Authors Betty Shamieh and Amy Tan were both subjected to trying appeal to others. They both explore how they found themselves and attempt to tell readers to express their individuality. As American citizens, majority of us come from different backgrounds which gives us a broader perspective. We should try not to forget our roots and neither should we become entrenched in trying to appeal to others who see us under a different light. We as individual bring about diversity and cultural richness to America, hence we should not be afraid to communicate our ideas in a manner that represents who we are. When we constantly feel the need to compromise we often lose our identities and our own unique individuality. We are discrete individuals and we should utilize our differences, rather than trying to hide or forget them. If we do not s tand up and express our perspectives then others will express them for us. So, thus we need to communicate our ideas in an effective manner, while still retaining our original flavors in the salad bowl. Works Cited 1) Neweib, Janice. Mother Tongue by Amy Tan.

Matilda Essay -- essays research papers

Matilda   Ã‚  Ã‚  Ã‚  Ã‚  Too smart for her own good, is a legendary saying used for people that are so smart that at the end of their life it can be dangerous for them. In the fantastic story Matilda written by Roald Dahl, the author describes a young girl's life that is affected by lack of love and affection and her being too intelligent for her age and time. It was the beginning of summer in 1993 the climate was starting to get hot and the Wormwood family didn't pay much attention to Matilda and her incredible abilities. The local color and verisimilitude of the setting consists in the typical modern-day English village, lots of houses with gardens full of flowers infront of each house, people walking their dogs in the street, cars passing by, kids laughing, happy people all over the place, Matilda's friends running around following their lost red ball. Matilda Wormwood, a remarkably bright little girl, had taught herself to read at the age of three; by the age of four she had pored a dozens of times over the only book to be found at her parents house, Easy Cooking. While her mother was playing bridge all day and her used car salesman father was at work, Matilda walked to the public library and read books all afternoon. Matilda's parents were both so warmless and so wrapped up in their own silly little lives that they failed to notice anything unusual about Matilda. Afterward, Mr. Wormwood decided to take Matilda to school; in school Matilda found lots of ...

Tom Ang

Tom Ang grew up playing the clarinet. His dream was to become the first clarinet for the London schools symphony orchestra. he never made his dream in the musical world so he turned to the world of Medicine. he stayed in the Nottingham medical school for 3 years before he decided that this wasn't his passion either. he traveled to Hong Kong many years later and saw the beauty that he has never seen before. he then decided that this was his passion. to photograph the things people pass by everyday and to have a new world seen from right under our noses.He traveled to mexico to see not the poverty that is riddled throughout the land but to see the happiness that the families share even in the dark times. to show that it doesn't matter how much money you have to care for your family but how much heart. In his trip to mexico he realized that people don't want to always see the darker things in life that may seem interesting. he saw past the mirror that makes other people resilient and ch ooses to take pictures of the obvious things that others won't see.Tom decided that these pictures are the ones that show true heart and are willing to break the boundaries of normal lifestyle and show the cultures of many other races and nations. he also visits New York in that same year and tries to show New York from the outside worlds perspective. this meaning the poverty that surrounds New York so that it seems similar to mexico and the other countries. he soon realizes that these people are not like the ones in his other photographs that these people are dangerous and are not fueled by heart and love but they are fueled by hate and greed.He tries to capture these pictures as best as he can but did not post many because he believed that they didn't show the true feeling he felt when taking the photos and it doesn't have the same effect if it doesn't feel the same. At this point in time Tom started working with Fay Godwin as his assistant. he was asked if he knew how to print be cause that would be his basic job, and of course he responded yes. He claims that he was a total amateur and did not want to admit it because he needed the job. Yet for some reason she kept him on the team and trained him to become a better printer so he can print for her book and galleries.Tom traveled back to Hong Kong and took many more homescape photos while on his vacation there. Tom had upset a large nest of bees when photographing there. they attacked him very vigorously and sent him to the operating table. he says that his life could have ended right there. after his battle with the bees he traveled to japan in search of a dream boat that kept appearing every time that he would dream. he searched through all of japan taking pictures of boats so he could find it. but sadly this boat was never found.

INTRODUCTION1.1 Background of the StudyA newspaper refers to a printed publication consisting of folded unstapled sheets and containing news, feature articles, advertisements, and correspondence. It occupies an important place in our life. It plays an important role in shaping the destiny of a country. Every morning a newspaper brings up news from every corner of the world. A good newspaper is a sign of good civilization and progress of a country. It satisfies the demands of the literates, it covers a wide range of subjects like sports, advertisement, education, trade etc. the government makes important announcements only through a newspaper. It plays a very important role in a democratic country.It is a true mirror of the public opinion. The importance of newspapers can’t be ignored in the social uplift of the country. Hence, newspapers still enjoy an integral part in the society (Prajwal N., 2010). The Sumilang Group of Publications, the publisher of The Sumilang Chronicles and other scholastic newsletters, is the official publication of Cavite State University – Silang Campus. The organization is built under Republic Act No. 7079 or the Campus Journalism Act of 1991. According to Section 2 of R.A. 7079, â€Å"It is the declared policy of the State to uphold and protect the freedom of the press even at the campus level and to promote the development and growth of campus journalism as a means of  strengthening ethical values, encouraging critical and creative thinking, and developing moral character and personal discipline of the Filipino youth.In furtherance of this policy, the State shall undertake various programs and projects aimed at improving the journalistic skills of students concerned and promoting responsible and free journalism.† It is the responsibility of the organization to provide the members of the academic community with all the current news and updates happening around the campus which includes university and academic n ews, development news, community news, features, sports news, literary, opinion and photo essays. However, release of newsletter inside the university is not frequent unlike other schools, resulting to lack of information on the latest happenings inside the university.To address this problem, the proponents have come up with a proposed study to develop a website for The Sumilang Group of Publications, in which the current news and events of the university can be read and accessed anytime and anywhere by the students, faculty members, and administrators of the university.1.2 Statement of the ProblemAccording to some interviews conducted to the members of the The Sumilang Group of Publications, they are experiencing difficulties with their operations. With the traditional process in communicating with other members, they are affected in terms of reaching out to its members, thus resulting in miscommunication. The manual system of checking and passing of news articles are also affectin g the operations of the organization.Some articles are not following the proper process in proofreading, thus resulting to multiple unseen errors. As observed by the proponents, developing a website for The Sumilang Group of Publications of Cavite State University – Silang Campus will greatly benefit the organization. With this, the students, faculty members and administrators, will now have access to information on the latest news and updates inside the university online. The organization will also have the ability to import and manage their data and articles with the help of the website.1.3 ObjectivesThe general objective of this study is to create a website for The Sumilang Group of Publications of Cavite State University – Silang Campus. Also, this study has the following specific objectives: a. To design a website that will highlight the official publication of the university; b. To disseminate the latest news and events inside the university in real time; c. To d evelop the system as intended, and;d. To test and implement the system.1.4 Significance of the StudyThe project design, â€Å"Website for the Sumilang Group of Publications in Cavite State University – Silang Campus†, was developed in order to address the need of the organization in managing updates about the latest news and events happening inside the university. Also, this was intended for the rapid processing of articles to elevate their services.This study is also intended to benefit the writers of the Sumilang Group of Publications because it will let them post their articles in a more secure and convenient manner. Also, the students and instructors of Cavite State University – Silang Campus will benefit with this website because they can now coordinate and contribute in ensuring that all information found are correct and well-updated.Multitasking will also be more efficient with the help of this project design. The members will now be able to save time in submitting their articles, while other staffs and members can now handle other tasks, thus making their operations more efficient. Also, the university can save resources, time, and energy in producing accurate reports that in return, will eliminate time hindrances and data inconsistencies.As for the students and instructors that will serve as the readers, this system can assure that all data found on the website are timely and accurate; Giving the impression that the Sumilang Group of Publications is a credible organization that will result in more confidence for the members of  the organization in order for them to continue serving the academic community. Scope and LimitationThis project design is only limited in the development of a website for The Sumilang Group of Publications of Cavite State University – Silang Campus with the following features: Add, edit, and feature news articles, display news and announcements, and highlight the Sumilang Group of Publications as t he official publication of Silang Campus. In order to develop the project design, the researchers used a single unit of computer with the following specifications: Intel ® Atomâ„ ¢ processor N270 (1.60 GHz, 533 MHz FSB, 512 KB L2 cache) processor, 2GB memory and 500GB hard disk storage. For the software, the researchers used Microsoft Windows 7 Ultimate (32-bit) operating system, PHP for the scripting language, and MySQL for the database.In order to properly address the problem of the organization and to produce software that will meet certain standards, the researchers used the Rapid Application Development (RAD). RAD is a software development process used to speed the overall development time of a system. The objective of RAD is first to decrease development time, which will decrease expense, by involving end-users in every phase of the software development life cycle. There are four phases in RAD as shown in Figure 1. The first phase is requirements planning.Requirement plan ning is the process of identifying the solution to the current problem. The user design phase is the phase when the end-user gives thoughts on how the system should be designed. This would be a non-technical design. It is a local design of the system. The next phase is the construction phase, which is the actual building of the system. The final phase is the installation of the system, which is called the cutover phase. Included in this phase is the testing and training of the users.

Isolation and Analysis of Essential Oils Using Gas Chromatography Essays

Isolation and Analysis of Essential Oils Using Gas Chromatography Essays Isolation and Analysis of Essential Oils Using Gas Chromatography Paper Isolation and Analysis of Essential Oils Using Gas Chromatography Paper Isolation and Analysis of Essential Oils using Gas Chromatography Lyndon Justin T. Guzman Institute of Chemistry, University of the Philippines, Diliman, Quezon City Date Performed: February 2; February 4, 2011 Date Submitted: February 18, 2011 Abstract The purpose of this experiment is to isolate the essential oil from eucalyptus leaves as a pure compound; moreover, the components of the essential oil, camphor and limonene, will be then separated using gas chromatography technique, identify the components by their retention times, and compute for the concentration and percentage content of each component by their peak areas and peak heights. The volatile oil from eucalyptus leaves was isolated with the use of steam distillation setup, then using a separatory funnel to pipette out the extract from the distillate. A gas chromatography, with nitrogen gas as the carrier gas and a flame ionization detector, was used to separate and characterize the components of the essential oil. The retention times, peak areas, and peak heights were obtained for qualitative and quantitative analysis. A percentage of 0. 05% and 2. 85% were obtained as the content of camphor and limonene in the extracted oil, respectively. It also goes to show that limonene has greater concentration than that of camphor in the essential oil extract. Indeed, steam distillation and gas chromatography techniques are essential methods for extracting essential oils and separating natural compounds from plants. I. Introduction Gas chromatography is used for separations of volatile or reasonably volatile organic liquids and solids. In this method of chromatography, the components are partitioned between a liquid coating on the column (the stationary phase) and an inert gas (the mobile phase). The stationary phase for gas chromatography is usually an organic polymer coated on the inside of a tube, such as long capillary, and the mobile phase is an inert gas, such as hydrogen, helium, or nitrogen. (Druelinger, 2000) Figure 1. Schematic diagram of a gas chromatographic system. cee. vt. edu/ewr/environmental/teach/smprimer/gc/gc. html A small volume (1-10 ? L) of a mixture of volatile substances (usually dissolved in a solvent) is injected by syringe onto a heated column through which an inert carrier gas is flowing. The heat applied, as well as the gas flow, helps the molecules from the sample travel through the column. Smaller, more volatile molecules generally emerge first from the opposite end of the column and are detected. The detector is connected to a recorder/data system, which shows a deflection when a sample passes the detector in proportion to the amount of sample detected. Compounds are eluted through an exit port either in an intact form or as combustion products, depending on the type of detector used. (Druelinger, 2000) The characteristic aromas of plants are due to the volatile oils, or also known as essential oils, which have been used since antiquity as a source of fragrances and flavorings. These oils occur in all living parts of the plant; they are often concentrated in twigs, leaves, flowers, and seeds. Essential oils are generally complex mixtures of hydrocarbons, alcohols, and carbonyl compounds mostly belonging to the broad group of plant products known as terpenes. (Dalrymple and Moore, 1976) One of the many types of samples easily characterized by the technique of gas chromatography is the essential oil. These essential oils are isolated from the plant tissue by steam distillation. Since organic compounds are generally miscible with one another, this phenomenon is usually observed only when one of the liquids is water with one or more immiscible organic liquids; in these cases, the distillation process is called steam distillation (Ault, 1983). The technique of steam distillation is based upon the principle that each component of immiscible liquid mixtures contributes to the total vapor pressure as if the other components were not there (Druelinger et. l. , 2000). As the temperature of such a mixture in an apparatus open to the atmosphere is raised, the vapor pressure of each substance increases until the total vapor pressure equals the pressure of the atmosphere. Since the total vapor pressure is the sum of the individual vapor pressures, the total vapor pressure must become equal to atmospheric pressure at a temperature below the boiling point of either pure substance (Ault, 1983). The mixture thus distills at a temperature below the boiling point of either pure component. This can be explained using a combination of Dalton’s and Raoult’s Law: Patm = XAPÂ °A + XBPÂ °B where Patm is the atmospheric pressure, XA and XB are the mole fractions of compounds A and B, and PÂ °A and PÂ °B are the vapor pressures of pure liquids A and B. Their individual contributions are dependent on their respective mole fractions, and both liquids contribute to the vapor pressure of the system (Institute of Chemistry, UPD, 2010). In this experiment, a major constituent of volatile oils from eucalyptus leaves will be isolated as a pure compound with high purity via steam distillation. These essential oils are camphor and limonene and by using the gas chromatography technique, the different components of the eucalyptus essential oil will be separated. This experiment also aims to manipulate the gas chromatography system and change conditions in order to effectively and efficiently separate the components, and therefore achieve a good resolution. The components will be identified by determination of their retention times relative to those of a homologous series of n-alkanes by co-injection with authentic (standard) samples. II. Methodology Extraction of Essential Oils by Steam Distillation A steam distillation setup was prepared as shown in Figure 2 below (Note 1). The sample (Note 2) was cut into small pieces and an amount enough to fill three-fourths of a 1-L round bottom flask was collected. 400-mL distilled water was weighed and added into the flask. The mixture was steam distilled rapidly until you have about 100 mL of the distillate. Figure 2. Steam distillation setup. pharmainfo. net/reviews/fractional-distillation-binary-solvent-mixture The distillate was placed in a separatory funnel and 2. 0 g NaCl was added. The funnel was left to stand until separation of layers occurred. All the extract was then pipetted out (Note 3). The mixture was dried by adding enough anhydrous sodium sulfate to the mixture until the sodium sulfate swirled freely. If the entire drying agent clumped, another spatula-full anhydrous sodium sulfate was added. The mixture was then swirled. The mixture was dry if there were no visible signs of water and the drying agent flowed freely in the container. The essential oil and aqueous distillate were stored in separate tightly-sealed, properly-labeled containers (vials) in the freezer for future use in the FT-IR analysis experiment or GC experiment or special project (Note 4). Gas Chromatographic Analysis of Essential Oils Solution Preparation 1. Reference Solution. Separate stock solutions of 500 ppm of camphor and limonene in acetone were prepared. 50-300 ppm working standard solutions were also prepared (50, 100, 150, 200, 250 ppm) (Note 5). 2. Essential Oil Extract. 0. 5 mL of the pure extract (from steam distillation) was measured and diluted with acetone in a 10-mL volumetric flask. Instrumentation Gas chromatography was performed using a Shimadzu GC-14B using Equity 1 (30 m x 0. 25 ? m ID, 0. 25 mm film thickness) capillary column with N2 as a carrier gas. The following were the operating conditions: N2 flow rate| 1. 0 mL/min| Column temperature| initial 50Â °C (at 4 mins)| Ramp| 20Â °C/min to 210Â °C| Injector temperature| 200Â °C| Detector temperature| 250Â °C| Before the start of the experiment, the GC must have warmed up. Refer to the GC condensed procedure. Gas Chromatographic Analysis 1. 0 ? L of the standard camphor solution was injected and its chromatogram was generated. The procedure was repeated using limonene standard solution. The recorded retention times and peak areas of these substances were noted. 1. 0 ? L of the test solution (essential oil extract) was injected. Using the retention times determined from the chromatogram with the standard solution, the components of the standard solution was located on the chromatogram obtained with the test solution (Note 6). After all solutions have been injected and data computer-processed, the GC was left to run at the highest column temperature used in the experiment with the N2 gas flowing at a slower rate than the experimental flow rate for 15-20 minutes. The injector temperature was set to room temperature and slowly lowered the column temperature down to room temperature with the N2 gas still flowing in the system. Once everything reached room temperature, the gas flow was left to stand for another 10-15 minutes, after which the GC can be turned off. Notes 1. Boiling chips were added to the steam generator and sample flasks. 2. Each group must use different plant samples. 3. There should be two layers after the addition of NaCl solution. One was mostly water. The other was mostly extracted oil. To find out which is which, a small amount of water was added to the flask, whichever layer dissolved the water drop was the aqueous layer. The layer of essential oil was then carefully pipetted out. . If you have to get more of the organic layer out of the water, you can perform a back-extraction (solvent extraction) experiment. 5. All standard and sample solutions were stored in a well-filled, airtight container, protected from light and a temperature not exceeding 25Â °C. 6. The assay was not valid unless the number of theoretical plates calculated for the peak due to limonene at 110Â °C was at leas t 30000; the resolution between the peaks corresponding to limonene and cineole was at least 1. 5. Waste Disposal All solid wastes were disposed in the trash can. Waste acetone was poured into properly labeled waste container exclusively for acetone. Do not pour waste acetone in the sink! III. Results and Discussion The extraction of the essential oils, camphor and limonene, from the eucalyptus leaves sample was carried out using the steam distillation technique. camphor Figure 3. Structural formulas for camphor and limonene. The boiling point of the oily, aqueous distillate will never exceed the boiling point of water. This is because both water and the oily component each contribute to the total vapor pressure as if the other component was not present. The mixture boils when the combined vapor pressures of water and oil equal the atmospheric pressure. The oil has a small, but significant vapor pressure at 100Â °C, so that the boiling point of the mixture will be just below the boiling point of water. (Druelinger, 2000) The mass of the eucalyptus leaves that were extracted was 112. 98 g. 100 mL of the distillate was produced from the steam distillation. Only a small amount of oil was extracted within the distillate by a separatory funnel. The components of the oil sample were then separated and characterized using the gas chromatography technique with a flame ionization detector. Nitrogen gas served as the carrier gas or the mobile phase that moved the sample throughout the column. The chromatograms, plots of detector response versus time, of the standards and the sample were taken. Retention times were noted for qualitative analysis. Peak areas and peak heights were also recorded for and quantitative analysis of the essential oils. Table 1. Retention times of camphor and limonene standard and sample solutions. Solution| Retention Time (min)| pure standard camphor| 9. 021| pure standard limonene| 7. 908| extracted camphor sample| 9. 347| extracted limonene sample| 7. 89| From the given data above for the retention time, the retention time of the camphor and limonene from the standard solutions, 9. 021 min and 7. 908 min, respectively, were close to the retention time of the camphor and limonene with that of the sample solution, 9. 347 min and 7. 889 min. It was deduced that the camphor and limonene from the sample solution were present compounds in the extrac ted oil from eucalyptus leaves. Below is a table shown for the resulted peak areas and peak heights from the chromatograms of camphor and limonene standard solutions. Table 2. Peak areas and peak heights of camphor and limonene standard solutions. Solution| Peak Area| Peak Height| pure standard camphor| 46848| 17109| 50 ppm| 4427| 1113| 150 ppm| 12904| 4627| 200 ppm| 20417| 6065| 250 ppm| 15683| 5282| pure standard limonene| 56156| 20681| 50 ppm| 4419| 1236| 150 ppm| 15058| 4946| 200 ppm| 20464| 6452| 250 ppm| 20875| 5913| Figure 4. Camphor standard solutions vs. Peak area. Figure 5. Camphor standard solutions vs. Peak height. Table 3. Determination of the concentration of camphor component in the sample. Camphor Sample| Value| Concentration (ppm)| Peak Area| 5820| 67. 8| Peak Height| 1544| 61. 57| From the plotted calibration curve on the peak height and peak area for the camphor component, a regression equation is formulated in each curve with linearities almost equal to 1. From the acquired data on peak area and peak height of the camphor sample, the concentration of the camphor is 67. 98 ppm when the peak area is 5820 and 61. 57 ppm when the peak heigh t is 1544.

Limonene Sample| Value| Concentration (ppm)| Peak Area| 306384| 2875. 39| Peak Height| 102881| 2943. 95| From the plotted calibration curve on the peak height and peak area for the limonene component, a regression equation is formulated in each curve with linearities also almost equal to 1. From the obtained data on peak and peak height of the limonene sample, the concentration of the limonene is 2875. 39 ppm when the peak area is 306384 and 2943. 95 ppm when the peak height is 102881. To determine the percentage content of the components of the essential oil, the area normalization method is applied. Determining the areas beneath all of the peaks of a chromatogram enables to assign percentages to each of the components of a sample. Table 5. Determination of the percentage content of camphor and limonene sample. Component| Area| Total Area| % Content| camphor| 5820| 10766407| 0. 05%| limonene| 306384| | 2. 85%| Using the formula for area normalization, the computed percentage contents for camphor and limonene are 0. 05% and 2. 85%, respectively. This suggests that there is a greater amount of limonene in the oil extracted from the eucalyptus leaves than that of camphor. The very low percentage implies that extracting and separating natural organic compounds from essential oils give you a very low yield that’s why you need to have huge amounts of starting material to extract from to get a relatively high percentage of its components. IV. Conclusion In this experiment, the essential oil from eucalyptus leaves was isolated as a pure compound by steam distillation. The components of the eucalyptus essential oil, camphor and limonene, were separated using the gas chromatography technique having a flame ionization detector. The components were also identified through determination of their retention times and were confirmed that camphor and limonene are present, having a retention time of 9. 347 and 7. 889, respectively. Calibration curves on peak areas and peak heights on camphor and limonene were formed. Concentrations of the components were calculated and gave 67. 98 ppm and 61. 57 ppm for camphor, and 2875. 39 ppm and 2943. 95 ppm for limonene. The percentage contents of the components were also determined. The essential oil extracted constituted 0. 5% camphor and 2. 85% limonene. Steam distillation is a useful method for isolating high-boiling liquids, such as oils, from other non-volatile organic compounds, such as waxes, complex fats, proteins, and sugars (Druelinger, 2000). Natural oils can be isolated readily by steam distillation. Individual compounds can be separated from the essential oil by gas chromatography wherein the components of a vaporized sample are separated as a consequence of bei ng partitioned between a mobile gaseous phase and a liquid stationary phase held in a column. Gas chromatography is the most widely used technique for qualitative and quantitative analysis for analysis times are short, very small amounts of sample are required and an ideal tool for the microscale and miniscale organic laboratories. If you want to obtain large percentage of compounds from the extracted essential oil, you need to have huge amounts of eucalyptus leaves and it will take you a long time to steam distill. The standards should be injected under the same set of conditions for if not, this will lead to erroneous comparisons of data. You can manipulate some parameters like type of column, carrier gas flow rate, injector temperature, and column temperature to compare some effects on the quantitative breakdown of the experiment. V.

The gas chromatography technique is used for separations of volatile or reasonably volatile organic liquids and solids. 2. Thermal conductivity detectors (TCD), flame ionization detectors (FID), and electron capture detectors (ECD) are commonly used type of detectors. The thermal conductivity detector, which was one of the earliest detectors for gas chromatography, senses a difference in thermal conductivity of gases eluting from a GC column. The thermal conductivities of helium and hydrogen are roughly 6 to 10 times greater than those of most organic compounds. Thus, even small amounts of organic species cause relatively large decreases in the thermal conductivity of the column effluent, which results in a marked rise in the temperature of the detector. (Skoog et. al. , 2004) Flame ionization detectors, the most widely used and applicable detector for GC, consist of a flame fueled by hydrogen gas. Functional groups, such as carbonyl, alcohol, halogen, and amine, yield fewer ions or none at all in a flame. The detector is insensitive towards non-combustible gases such as H2O, CO2, SO2, and NO2. These properties make the FID a most useful detector for the analysis of most organic samples, including those that are contaminated with water and the oxides of nitrogen and sulfur. (Skoog et. al. , 2004) The electron capture detector has become one of the most widely used detectors for environmental samples because this detector selectively responds to halogen-containing organic compounds, such as pesticides and polychlorinated biphenyls. (Skoog et. al. , 2004) 3. An elution with a single solvent or a solvent mixture of constant composition is isocratic. For samples with a broad boiling range, it is often desirable to employ temperature programming, whereby the column temperature is either increased continuously or in steps as the separation proceeds. 4. polydimethyl siloxane – general-purpose nonpolar phase, hydrocarbons, polynuclear aromatics, steroids, PCBs polyethylene glycol – free acids, alcohols, ethers, essential oils, glycols 5% phenyl-polydimethyl siloxane – fatty acid methyl esters, alkaloids, drugs, halogenated compounds 50% cyanopropyl-polydimethyl siloxane – polyunsaturated fatty acids, rosin acids, free acids, alcohols .

How Presidents Have Used Their Power To Pardon

How Presidents Have Used Their Power To Pardon The President derives the power of pardon from Article II, Section 2 of the U.S. Constitution, which gives the president power to grant reprieves and pardons for offenses against the United States, except in cases of impeachment. A reprieve reduces the severity of a punishment, but the person remains guilty. A pardon removes both punishment and guilt, which is why pardons are more likely to be controversial. The process for obtaining a pardons begins with an application to the Department of Justice Office of the Pardon Attorney. The DOJ consults with other lawyers and judges for recommendations; the FBI runs a check on the applicant. After winnowing the applicants, the DOJ provides a list of recommendations to the office of the White House Counsel. Historical Pardons Historically, Presidents used the power to pardon to heal rifts in the national psyche. As President Bush said on 24 December 1982, When earlier wars have ended, Presidents have historically used their power to pardon to put bitterness behind us and look to the future. For example, George Washington pardoned leaders of the Whiskey Rebellion; James Madison pardoned Lafittes pirates after the War of 1812; Andrew Johnson pardoned Confederate soldiers after the Civil War; Harry Truman pardoned those who violated World War II Selective Service laws; and Jimmy Carter pardoned Vietnam War draft dodgers. The modern-day pardon, however, has taken a decidedly more political turn. And it may help its recipient find a job and regain the right to vote. Nixon In modern history, the most controversial pardon is probably the 1974 pardon of former President Richard Nixon, issued by President Gerald Ford. Ford assumed the presidency on 9 August 1974, the day after President Nixon resigned over Watergate, pending impeachment. Ford pardoned Nixon on 8 September 1974. Although Carter made a campaign issue of the Nixon pardon, in retrospect Fords action was brave (it was political suicide) and helped a divided nation begin to heal. Iran-Contra On 24 December 1992, President George Bush pardoned six Reagan administration officials involved in the Iran-Contra Affair: Elliott Abrams, Duane R. Clarridge, Alan Fiers, Clair George, National Security Adviser Robert C. Bud McFarlane and Secretary of Defense Caspar W. Weinberger. He compared their actions to those pardoned by Madison, Johnson, Truman and Carter: In many cases, the offenses pardoned by these Presidents were at least as serious as those I am pardoning today. Independent Counsel Lawrence E. Walsh was appointed in December 1986 to investigate the Iran/Contra affair; subsequently, Walsh brought charges against 14 people. Eleven were convicted; two convictions were overturned on appeal. Two were pardoned before trial, and one case was dismissed when the Bush Administration declined to declassify information necessary for trial.President Bush pardoned six Iran/Contra participants on 24 December 1992. Post-Trial Pardons Elliott Abrams   Pleaded guilty October 7, 1991, to two misdemeanor charges of withholding information from Congress about secret government efforts to support the Nicaraguan contra rebels during a ban on such aid. He was sentenced on November 15, 1991 to two years probation and 100 hours community service. The second President Bush appointed Abrams as Special Assistant to the President and Senior Director on the National Security Council for Near East and North African Affairs. Alan D. Fiers, Jr.   Pleaded guilty July 9, 1991, to two misdemeanor counts of withholding information from Congress about secret efforts to aid the Nicaraguan contras. He was sentenced on January 31, 1992 to one year probation and 100 hours community service. Pardoned. Clair E. George   Indicted September 6, 1991, on 10 counts of perjury, false statements and obstruction in connection with congressional and Grand Jury investigations. Georges trial on nine counts ended in a mistrial on August 26, 1992. Following a second trial on seven counts, George was found guilty December 9, 1992, of two felony charges of false statements and perjury before Congress. His sentencing hearing was February 18, 1993. Pardoned before sentencing occurred. Robert C. McFarlane   Pleaded guilty March 11, 1988, to four misdemeanor counts of withholding information from Congress. He was sentenced on March 3, 1989, to two years probation, $20,000 in fines and 200 hours community service. Pardoned. Pre-trial Pardons Duane R. Clarridge   Indicted November 26, 1991, on seven counts of perjury and false statements about a secret shipment of U.S. HAWK missiles to Iran. The maximum penalty for each count was five years in prison and $250,000 in fines. Trial date set for March 15, 1993. Pardoned. Caspar W. Weinberger   Indicted June 16, 1992, on five counts of obstruction, perjury and false statements in connection with congressional and Independent Counsel investigations of Iran/ contra. On September 29, the obstruction count was dismissed. On October 30, a second indictment was issued, charging one false statement count. The second indictment was dismissed December 11, leaving four counts remaining. The maximum penalty for each count was five years in prison and $250,000 in fines. Trial date set for January 5, 1993, trial date. Pardoned. Dismissal Joseph F. Fernandez   Indicted June 20, 1988 on five counts of conspiracy to defraud the United States, obstructing the inquiry of the Tower Commission and making false statements to government agencies. The case was dismissed in the District of Columbia for venue reasons on the motion of Independent Counsel. A four-count indictment was issued in the Eastern District of Virginia on April 24, 1989. The four-count case was dismissed November 24, 1989, after Attorney General Richard Thornburgh blocked the disclosure of classified information ruled relevant to the defense. The U.S. Court of Appeals for the Fourth Circuit in Richmond, Va., on September 6, 1990 upheld Judge Hiltons rulings under the Classified Information Procedures Act (CIPA). On October 12, 1990, the Attorney General filed a final declaration that he would not disclose the classified information. From the  Walsh Iran/Contra Report. In addition, Bush pardoned Edwin Cox Jr., whose family contributed nearly $200,000 to the Bush familys campaigns and to Republican campaign committees from 1980 to 2000, according to documents obtained by  CNN. Cox pleaded guilty to bank fraud in 1988, served six months in prison and paid $250,000 in fines. In addition, his father (Cox, Sr.) is a Bush Presidential Library trustee who contributed between $100,000 and $250,000 to the Bush Presidential Library. A complete  list of Bushs pardons  (1989-1992) President Clintons Pardons President Clintons most controversial pardon was of billionaire financier Marc Rich. His connection with the political and business elite of both parties demonstrates that the differences among those in power are less distinct than the differences between those in power and those out of power. For  example: After hiring prominent Republican lawyers during the Reagan and Bush administrations- Leonard Garment, former Nixon White House counsel, William Bradford Reynolds, once an official of the Reagan Justice Department, and Lewis Libby, now chief of staff to Vice President Richard Cheney- Rich hired a top Democratic lawyer, Jack Quinn, to give him direct access to Clinton. Quinn, former White House counsel, runs his law practice with Ed Gillespie, a key Bush adviser and former head of the GOP. In addition, Clinton pardoned Susan McDougal (Whitewater), former Housing Secretary Henry Cisneros (lied to FBI investigators about payments to his mistress) and  ex-CIA chief  John Deutch (forced out at the CIA when he contradicted White House claims that U.S. missile strikes on Iraq were effective).Review the  list of Clintons pardons  (1993-2000) President Bushs Pardons As the end of President Bushs term drew near, he had pardoned about half as many people as his prior two-term predecessors, Clinton and Ronald Reagan. Bush has issued pardons for many petty crimes committed decades in the past, ranging from possessing marijuana to moonshining. Just before Thanksgiving 2008,  President Bush pardoned 14 and commuted the sentence  of another two. This brought his pardon total to 171 and commutations total to eight. In one of the most high profile cases of his Administration, that of Scooter Libby, President Bush did not grant a pardon. He did, however, commute Libbys sentence. Another high-profile commuted sentences was that of  hip-hop musician John Forte, who was convicted in 2001 on drug smuggling charges. In Texas. Just  before Christmas, Bush pardoned Isaac Toussie who pleaded guilty in 2001 to using false documents to have mortgages insured by the Department of Housing and Urban Development, and in 2002 to mail fraud, admitting that he had persuaded officials in Suffolk County to overpay for land. Bush rescinded the pardon the next day after press reports revealed that his father, Robert Toussie, recently donated $30,800 to Republicans. Bush let  stand a pardon  issued for Alan Maiss, who had contributed $1,500 to the presidents 2004 re-election campaign; he served one year of probation. In 1995, Maiss failed to report a fellow gaming executives alleged ties to organized crime. Bush had  pardoned 19  and provided clemency for one.

High Bypass Gas Turbine Engine - Coursework Example Application of Newton’s First Law related to thrust: # If thrust and Drag are equal, the aircraft maintains a constant speed. # If thrust is increased, the speed of aircraft increases. Since drag is proportional to speed, drag also increases till it equals thrust. When drag again equals thrust, the aircraft travels at constant higher speed. Application of Newton’s Second Law related to mass flow and exit velocity: Force Mass * Acceleration F ma F=kma When SI system is used,the basic unit of force is the Newton, which is the force that will accelerate unit mass of 1 kilogram at a rate of 1 metre per second per second. Under these conditions, the constant k is unity. Therefore, F=ma F=ma=m di/dt=(m/ft) dV=d (mV)/dt =mass flow rate times change in velocity =(mv)dot Where â€Å"m dot†=Mass flow rate is the amount of mass moving through a given plane over a given period of time. Mass flow rate=r * V * A where r is the density and V is the velocity of the fluid passing through area A. This is denoted as m dot (m with a little dot over the top) m dot= r * V * A If we denote exit of the turbojet by ‘e’ and free stream by ‘0’, then we get, F= (m dot*V)e-(m dot *V)0 Thus by maintaining the exit velocity at much greater values than the velocity at intake, high thrust can be produced in turbojet engines (High Exit Velocity). Application of Newton’s Third Law related to thrust: Thrust is the reaction force developed in the forward direction by accelerating a mass of fluid or gas backwards to the rear of the engine. The turboprop propulsion system consists of a core engine and a propeller. The general principles in Application of Newton’s First Law and Third Law in Turboprop engines are the same as given in Turbojet engine. Application of Newton’s Second Law related to mass flow and exit velocity in Turbo Prop: The general thrust equation is F= (m dot*V)e-(m dot *V)0 This means that if the exit velocity is m aintained at a higher value than free stream velocity, and simultaneously, the engine flow rate (m dot) is kept as high as possible, the high engine flow will produce a high thrust in a turboprop engine. Even though a large amount of air is ingested, the change in velocity is very minimal between the intake and the exit so that the exit velocity is at a low value (Low exit velocity). Due to the large value of m dot, a high thrust is developed. Total Thrust= Thrust of Propeller Thrust of Core If we denote the free stream conditions by â€Å"0†, the propeller exit conditions by â€Å"1†, core exit conditions by â€Å"e† and core entrance conditions by â€Å"c†, then from the basic thrust equation we get: F=(m dot)0 * V1 – (m dot)0 * V0 + (m dot)e * Ve – (m dot)c * V1 In Turboprop engine, the mass flow rate through the propeller is much greater than that of core engine(High mass flow ). The mass flow rate entering the core is almost equal to th e mass flow rate exiting the core. The exit velocity from the core is almost the same as inlet velocity into the core(Low exit velocity). Hence the thrust equation can be rounded off to get: Thrust F=(m dot)0 * (V1-V0) + (m dot)e * (Ve-V1) High Bypass Gas Turbine Engine: The 5 basic modules- Along with a Detailed Description of operation of each. Inlet Components and Purpose: The intake also called the inlet serves three purposes, namely (1) recovering as much of the total pressure of the free air stream required for combustion, from free-stream conditions to the conditions and deliver this pressure to the entrance of fan or compressor.
