The Formation Of Copper And Oil Deposits Essay - 1117 Words

Gas and oil deposits are typically found inside sedimentary rocks because of decomposing plants and animals trapped in layers of rocks. These rocks being usually consisting of clay pieces, sand, and mud. These rocks are layered and deposited on sediment layers. The remains of small organic materials such as zooplankton and algae form petroleum. Vast quantities of these remains settled to sea or lake bottoms, mixing with sediments and being buried under anoxic conditions. The heat and pressure over millions of years have turned the mud to rock and the organic materials to petroleum. The formation of petroleum occurs in two steps. The first step is Diagenesis, the second step is Catagenesis. Diagenesis is the process of compaction on the low pressure and temperature conditions. This process includes any chemical, physical, and biological changes in sediments after the initial formation. However, the result of weathering and metamorphism is not considered. The organic materials contain proteins, lipids, and carbohydrates and they are rich in water. When they are deposited, as a result of chemical reaction, microbial action, and compaction the water is forced out and the proteins and carbohydrates are broken down to form waxy substances called â€Å"kerogen† and â€Å"bitumen†. Catagenesis is thermal degradation of kerogen due to increase in temperature in deeper burials. Catagenesis or cracking will turn the kerogen to hydrocarbon chains.

The Great Gatsby Bleak Perspective Essay - 1543 Words

â€Å"The Great Gatsby offers a bleak perspective on American society.† Discuss The novel â€Å"The Great Gatsby† written by F. Scott Fitzgerald tells the story of a group of people living on an imaginary city close to the New York city. the story is more concentrated on the character of Jay Gatsby, a mysterious rich man who making big parties to attract his love, Daisy Buchanan and how is he trying to win her. A deep reading of the novel shows that in addition to the love story, the writer is more concerned to shows the social life and relationships of people in American society in the 1920s. This essay will argue that the writer wanted to show the bleak perspective of American society on that time. In order to show this, the essay will†¦show more content†¦This evidence clearly shows that Daisy used her charm to catch a wealthy husband but since she is smart, she knows about Tom’s relationship with other women but she cannot do anything but suffering. She cannot even accept that Tom is the father of her child and she thinks that the chil d is her’s not Tom’s. This is shown by her saying that â€Å"she doesn’t look like her father. She looks like me†(p.112). Based on these pieces of evidence, even wealthy women who seemed to have a good life were enduring from their situation and had no power to control their own lives. Myrtle a woman from the lowest social class is living under the pressure of poverty and under the control of her needy husband.Both Myrtle and Gatsby pursuit the dream of changing their lives however, Gatsby has the ability to go to the New York but Wilson keeps Myrtle like a prisoner. Wilson even decided to move her to the â€Å"West Egg† and she could not do anything for her freedom because she was a woman and she was under the control of her husband and her escape from her husband led to her death. The writer shows her as the first person who was killed and Buchanans who were responsible for her death didn’t give any values to her. This clearly means that w omen from lower social class has no value in society and harm the most. She is optimistic to change her life by having affairs with Tom, however in addition to her husband,

Problems and Issues in the Philippine Educational System Notes About the Problems and Issues in the Philippine Educational System: A Critical Discourse by Prof. John N. Ponsaran Colonial historiography. We will write a custom essay sample on Problems in Education in the Phil or any similar topic only for you Order Now Most of the past and present teachers, book authors, and Social Studies consultants give heavier premium to the history of the colonizers in the Philippines, and not to the history of Filipinos. Mostly, this has been the case in the teaching of History subjects from the elementary to tertiary levels and will most likely perpetuate in the next generations to come. The history of the Filipino people and the colonial history of the Philippines are two different topics altogether. Internationalization of the division of labor. To a certain extent, the Philippine educational system conditions its students to be skillful in arithmetic and computer literacy, fluent in foreign languages (specifically English and Nihonggo), and docile in order to serve as workers of the transnational businesses of the advanced, capitalist countries. Take the case of the call center phenomenon in the Philippines, India and other developing states. Emasculation and demoralization of teachers. Teachers, more often than not, are victimized by the over-worked and under-paid policy of the system of the past and present dispensations. This leads to the emasculation and demoralization of their ranks. This probably explains why the teaching profession is not attracting the best and the brightest from the crop of students anymore. Expectedly, this will correspondingly result to the vicious cycle of mediocrity in education. Fly-by-night educational institutions. By any measure, the proliferation of fly-by-night educational institutions is counter-productive. In the long run, it produces a pool of half-baked, unprepared, and incompetent graduates. Alarmingly, the country is having an over-supply already. Some would even consider them as liabilities than assets. This case is true for both undergraduate and graduate studies. Culturally and gender insensitive educational system. Women, the common tao and the indigenous people are almost historically excluded from the Philippine historiography in favor of the men, heroes from Luzon and the power elite. Women are marginalized and trivialized even in language of education. Take the case of the terms female lawyer (as if lawyer as a profession is exclusive only to men) and manpower (which should have been human resources or human capital to be more politically correct). State abandonment of education. In the name of imperialist globalization, the state—in an incremental fashion—is abandoning its role to subsidize public education particularly in the tertiary level. This comes in the form of matriculation, laboratory and miscellaneous fee increases in order to force state colleges and universities (SCUs) to generate their own sources of fund. Ironically, the bulk of the budget (in fact, more than one-third in the case of 2005 National Budget) goes to debt servicing. Sub-standard textbooks. Some textbooks which are already circulation are both poorly written and haphazardly edited. Take the case of the Asya: Noon at Ngayon with an identified total number of more than 400 historical errors. Unfortunately, it is just one of the many other similar atrociously written textbooks which are yet to be identified and exposed. This is a classic case of profit-centeredness without regard to social accountability. Widespread contractualization. In the name of profit, owners and administrators of several private schools commonly practice contractualization among their faculty members. Contractual employees unlike their regular/tenured counterparts are not entitled to fringe benefits which consequently reduces the over-all cost of their business operation. Job insecurity demeans the ranks of the faculty members. Undue disregard for specialization. Some colleges and universities encourage their faculty pool to be generalists (under the guise of multidisciplinary approach to learning) in order to be able to handle various subjects all at once. But some faculty members have turned out to be objects of mockery and have lost their self-esteem since some of them were pushed to handle Technical Writing, General Psychology, Filipino, and Algebra at the same time. This is prevalent among some franchised academic institutions even if the subjects are already off-tangent their area of interest and specialization. Copy-pasting culture. Over-dependence to the cyberspace has dramatically reduced the capability of students (even teachers) to undertake research. Copy-pasting’ has even turned into a norm among some students whenever they are tasked to submit a research paper or even a film review. Needless to say, plagiarism has already transformed into a more sophisticated form in the context of today’s electronic age. Mcdonaldized education. The system, methodology, and even content of education in the Philippines are mere haphazard transplantation from the West. It is therefore Eurocentric, culturally insensitive, and no n-reflective of the local milieu. This is based on the xenocentric (foreign-centered) premise that other culture or system is far more superior than one’s own. The problem of non-sustainability and non-continuity. Teachers, administrators and publishers are all left in limbo whenever the DepEd would come up with another totally different directive from what it used to have in a rather very sudden interval. Take the case of the grading system, timeframe allotted to various subjects, MAKABAYAN program, readiness test, and learning competencies (LC). Poor regard for liberal art/education. Liberal education is intended to form a holistic individual equipped with communication, critical thinking, mathematical, creative, inter-personal and intra-personal skills. This explains why we also have Philosophy, Languages, Humanities, Natural Science, Social Science, Physical Education and even Theology in our college curriculum, and not only our major subjects. The curriculum is specifically designed to produce a total person, and not only a technical specialist. Unfortunately, the desired objective is not being met at all since liberal ducation is regarded only as a set of minor subjects. With the way these subjects are being handled (taking into account both content and methodology), students view the entire exercise as an unnecessary duplication of what they have already covered in high school. Equally alarming is the lack of enthusiasm and motivation exhibited by some professors to handle the subject especially if they believe that it has nothing to do with the course or ar ea of specialization of their students (say, Art Appreciation for Accounting majors or Algebra for Creative Writing majors). Education a purveyor of myth. Education has been very effective in mainstreaming and perpetuating the social myths in a subtle and indirect manner. Some of these myths are the perceived superiority of white, educated men, ‘official’ history as advanced by the western point of view, globalization as the only way to achieve economic development, and stereotypes against the minoritized and the disenfranchised. Further marginalization of the undersubscribed courses. In the name of profit and as a response to the dictates of the market forces, colleges and universities prefer to offer more courses in line with the health sciences like nursing, medical transcription, and care-giving. This is done at the expense of the already undersubscribed yet relevant courses like Area Studies, Pilipinolohiya (Philippine Studies), Development Studies, Philippine Arts, Art Studies, Community Development, Social Work, Islamic Studies, Clothing Technology, and Ceramics Engineering. Monolithic education. Some educators in the name of conservatism and for the sake of convenience, prefer the old-style teaching paradigm where they view themselves as the fountain of knowledge and their students as nothing but empty vessels to be filled up (banking method of education). Modern education has ushered in learner-centered approach to education (from being the sage in the stage to just a guide on the side). Atrociously boring teachers. As I always underscore, there are no boring subjects, only boring teachers. But at least we should recognize them because they still serve a purpose. They serve as bad examples.

Asthma Essay Example For Students

Asthma Essay subject = Heathtitle = AsthmaAsthmaWhat is Asthma ?Asthma is a disorder that affects 20% of Australians in their childhood. It causes airways to narrow making it difficult to breathe. Symptoms may include loss of breathe in cold weather, wheezing and whistling. It may occur periodically in sudden sharp attacks. When an attack occurs The muscles around the wind pipe tighten shrinking the airways. The wind pipe lining then swells (picture) and a mucus called phlegm develops causing the cough to intensify and slightly more painful. What are the Causes and Triggers for asthma ?Attacks of Asthma occur due to a blockage in the bronchial tubes. This blockage results from a spasm that narrows the windpipe causing breathing difficulty for the sufferer. Asthma Triggers are things that make Asthma worse. Usual triggers are Respiratory infections eg. Colds, flu, sore throats and bronchitisAllergic reactions sometimes cause Asthma eg. Pollen, foods, dust, animal fur or some seed. Air irritants (similar to Allergic reactions) eg. Cigarette smoke, gases or dust. Excessive/strenuous exercise can cause an Asthma attack. Emotional Stress can also trigger an Asthma attack. Symptoms of AsthmaSymptoms include wheezing from the chest or a slight whistling is heard when inhaling. Its even louder when exhaling. Tightness of the chest, lung and lung area are closely associated with Asthma. Treatment for asthmaThere is no cure for Asthma but there are steps that doctors take to help relieve the symptoms of Asthma. As a first step doctors try to remove or get the patient to avoid Asthma triggers such as animal dander (eg. Fur or hairs). These are very likely to trigger an Asthma attack. Places where animals dwell are advised to be kept clear of for a sufferer. Since it is impossible to remove or avoid all triggers there are medications that can be taken. Such as Anti Inflammatory Drugs : these reduce swelling of the windpipe and its lining. Oral Steroids prednisone and prednisolone quickly reduce inflammation during an attack. Inhaled medicines such as cromoyln sodium and inhaled corticosteroids keep inflammation from flaring up. Bronchodilators : relax the muscles which have tightened around the windpipe. Adrenergic bronchodilators (Beta 2 agonists) provide temporary relief but do not treat inflammation. These are available as an Inhaler or a tablet form. Unfortunately the tablets are slower and have a few side affects. Theophylline is available in a liquid, capsule or tablet form. This drug has a long duration of action making it a very good soother for night time Asthma. Ways of preventing asthmaThere are no ways of preventing Asthma because it is usually genetic, allergically related or following a dose of bronchitis, but there are ways to prevent it from flaring up and turning into an attack. A sufferer can be very careful about his or hers diet because the diet can greatly affect the Asthma. Due to allergic reactions etc. Staying away from pollens and animal fur settles down Asthma. The allergic reactions are the highest causes of Asthma. Make sure you always have medication with you such as Intal and Becotide. These preventative medicines will stop an attack occurring. SummeryFor an Asthma sufferer breathing can sometimes be a great difficulty due to the fact that at any time their wind pipe can shrink due to inflammation, making it very hard to breathe. But with the right medication eg. Inhalers and Theophylline their life can be much easier. If they also stay away from triggers such as pollen, fur and cigarette smoke the air ways may not be so vulnerable. Even if you dont have Asthma you should keep an eye out for the symptoms which are chest and lung tightness, wheezing and loss of breath especially in cold weather. .u29bef94ed62090cd0e19d1c6a81474f0 , .u29bef94ed62090cd0e19d1c6a81474f0 .postImageUrl , .u29bef94ed62090cd0e19d1c6a81474f0 .centered-text-area { min-height: 80px; position: relative; } .u29bef94ed62090cd0e19d1c6a81474f0 , .u29bef94ed62090cd0e19d1c6a81474f0:hover , .u29bef94ed62090cd0e19d1c6a81474f0:visited , .u29bef94ed62090cd0e19d1c6a81474f0:active { border:0!important; } .u29bef94ed62090cd0e19d1c6a81474f0 .clearfix:after { content : ""; display: table; clear: both; } .u29bef94ed62090cd0e19d1c6a81474f0 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u29bef94ed62090cd0e19d1c6a81474f0:active , .u29bef94ed62090cd0e19d1c6a81474f0:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u29bef94ed62090cd0e19d1c6a81474f0 .centered-text-area { width: 100%; position: relative; } .u29bef94ed62090cd0e19d1c6a81474f0 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u29bef94ed62090cd0e19d1c6a81474f0 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u29bef94ed62090cd0e19d1c6a81474f0 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u29bef94ed62090cd0e19d1c6a81474f0:hover .ctaButton { background-color: #34495E!important; } .u29bef94ed62090cd0e19d1c6a81474f0 .centered-text { display: table; height: 80px; padding-left: 18px; top: 0; } .u29bef94ed62090cd0e19d1c6a81474f0 .u29bef94ed62090cd0e19d1c6a81474f0-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u29bef94ed62090cd0e19d1c6a81474f0:after { content: ""; display: block; clear: both; } READ: I Agree with the Principal's Decision of Making Extracurricular Activities Mandatory Essay
