Reflective Journal - Assignment Example I can contribute to sustainable development by changing my lifestyle in meaningful ways. I can monitor my use of water so that I do not waste it or use it unnecessarily. I can also dispose of recyclable material properly and dispose of all waste appropriately. I can reduce my use of energy and fossil fuels with a view to reducing carbon emissions. When possible, I can also donate to charities for feeding the poor to reduce their reliance on the exploitation on marine life and other natural food sources. Lecture 2: The three main points were: Sustainable development became a state obligation via the Rio Declaration of 1992; states’ obligation are contradicted by various UN Resolutions grants states sovereignty over their natural resources; and that climate changes now requires public participation via the UN Framework Convention on Climate Change 1992. Tutorial 2: I contributed to answering the various questions raised in Tutorial 2. These questions related to the role of the UN in international environmental law, identifying the principles of environmental protection contained in the Rio Declaration of 1992, and various questions relative to the definition and legal nature of treaties and conventions. I observed that there was a significant problem in the context of international environmental law. The various instruments were only binding on states and do not make provision for non-state actors. It can therefore be assumed that non-state actors’ effect on the environment are covered by national law. Alternatively, as a non-state actor, I can choose to take the initiative to responsibly use only environmentally friendly goods and ensure that my choices and behaviour do not contribute to a depletion of natural resources. Lecture 3: Three main points are: As the earth’s resources are decreasing the world population is increasing; in the meantime, the world is experiencing climate change and carbon emissions from fossil fuels is the

Religion - Assignment Example Cinemas, sport, Shops, among others were only available from Monday to Saturday. In the same period, many Churches were built in the mushrooming post-war suburbs and established urban ministries were renewed. The post-war years’ economic prosperity turned going to church into a badge of upward mobility or something of a status symbol. To many affluent working class families aspiring to the ranks of the middle class, churchgoing was a product and a symbol of American affluence. A survey by Lyle Schaller, a church growth expert, indicated that during that time, of the American population, the attendance of adults in mainline churches was 47 percent male and 53 percent female. The fact that male started involving themselves with church activities at a high level made the church grow. Previously, hardly any man could go to church. This shortage was due in part to the industrial revolution that brought new working conditions. Men started working long hours at mines and factories some of which operated on Sundays. Others left town in search for jobs, which took them away from home and their familiar parishes leaving the churches to children, aged men, and women (Murrow, 2005). Therefore, we can attribute people’s returning to church to social, theological and spiritual reasons among others. In this period of the 1950s, Protestantism became extensive and through the Protestants’ vigorous proselytization, approximately 20 percent of the population was Protestant by the late 1950s. The methods that Protestant churches used included focusing their appeal on the lower classes. They took their Churches and clergy in smaller villages where the Roman Catholics had not reached and rather than using French, their clergy used Creole. They also built clinics and schools that provided the much-needed services. They also encouraged marriages and baptisms and performed them free of charge. Up to date, these methods still have an impact

Building a Fire to Fight Nature Essay Example for Free

Building a Fire to Fight Nature Essay Jack Londons title for the story To Build a Fire starts the reader off with a very basic idea; building a fire. Almost anyone can build a fire. All it takes is a match and some kindling. Londons story is about more then building a fire, though. This story is about a mans belief in himself, self-confidence and even arrogance, to such an extent that he doesnt recognize the power of nature around him. Londons story is more like a Man against Nature story. Londons To Build a Fire casts a clear image that in the ever long-lasting battle between man and nature, nature is not a force that should be reckoned with. The authors characters are even very general. The main character of the story is never given a name except to be called a chechaqua or newcomer in the land. The constant struggle of Man against the natural world and physical forces which threaten to undo him at any moment is expressed greatly by this story.(Colin) This is not a story about one individual person or one isolated incident, but a story used to illustrate a larger continuous gamble or battle between man and nature. London spends the first few paragraphs setting the physical scene. The setting is in Alaska along the Yukon River. It is close to the end of winter but the sun is still not yet in the sky. It is mentioned that this does not bother the man. The rest of the setting is described around the man and the places he has passed on this current journey and where else the trail leads in other directions. The description of the scenery is one of the most intriguing aspects of this story. London had a way of almost making the reader feel cold for the man in the story just by his descriptions of the surrounding territory. The Yukon lay a mile wide and hidden under three feet of ice. On top of this ice was as many feet of snow. It was all pure white, rolling in gentle undulations where the ice jams of the freeze-up had formed. North and south as far as his eye could see, it was unbroken white..(Charters, 910) The scene is set as beautiful, peaceful and cold. The harshness of this physical setting begins to become more and more clear as the story  progresses. Later the man notices that his spit is cracking and freezing before it reaches the ground. He remembers that at fifty degrees below zero spit will freeze when it hits the ground. Undoubtedly it was colder than fifty below.(911) This also means that there is at least 107 degrees of frost if it is truly 75 degrees below freezing. To increase the readers awareness of the cold, London describes how the mans breath is freezing on his whiskers and beard, the man is also chewing tobacco and with the temperature as cold as it is his cheeks and lips are numb and his spit tends to just end up on his beard and freezes in seconds. This man must be out of his mind to be out in the wilderness in these extreme climate conditions. Seeing a man that oblivious to the dangers of traveling alone in colder than fifty below weather, walking on ice, and making a fire under a snow covered tree should be enough to substantiate that he was not unlucky but just plain stupid!(Wilson) The man starts to grow this crystal beard of the color and solidity of amber.(912) The surroundings are beautiful, peaceful and cold but the man did not see the danger that nature could bring upon him. That it was too cold out to travel or that it could get worse was a thought that never entered his head.(912) The man had a native of the land with him. At the mans heels trotted a dog.(911) No name is ever given to the dog in the story. Another way for London to keep the story general and the focus on the theme. The dog is a big, native Husky, a brother to the wild wolf it had the instincts to respect nature. The dog knew the temperature was too cold to be traveling but stayed at the mans heels. The dog plays a dual role in this story. He plays the mans conscience and natures voice and personification. Often a dog can reflect the same personality and character traits as its owner. Dogs are extremely intelligent creatures and will reflect and behavior that they are exposed to for lengthy periods of time.(Feinson, 127) The man treats the dog the same way he treats nature; with no respect. The dog is just a tool, a sled dog and later considered expendable to possibly save the mans life. The man treats nature much the same way. The dog also shows at  the end how nature moves on. The dog stays to watch the man as he dies and once the dog realizes the man is dead he runs off to the cabin where there are other food providers and fire providers(921) The protagonist in the story is the unnamed man. Hes a newcomer to this area of Alaska and it his first winter. He is on his way to a cabin at a claim where he will meet up with the boys. London refers to him as a man without imagination but, quick and alert in the things of life.(910) It is this lack of imagination that makes the man unable to believe or heed the warnings of the veteran Alaskan men who told him not to travel alone when it is fifty below. One needs to have a second person to try and start a fire if the first person should fail. But, the man in the story is over confident. He stops once and makes a fire without a problem to thaw his face so he can eat his lunch. The man doesnt notice how much the dog wants to stay at the fire. He doesnt respect the instincts of the native animal. The trail follows along a creek, which is frozen but has natural springs along it that create small pools of water with thin ice and coatings of snow to cover them up. The man almost prides himself on how well he can spot these warning signs of possible danger. He also is increasingly happy with the pace he is keeping. The man soon falls into one of natures little traps, a small pool of water, and has only a few minutes to build a fire and get warm and dry before he freezes to death. He tries to stay as calm as possible but in his haste doesnt pick a good spot to build a fire. He realizes too late when the heat from the fire he has just built starts to melt the snow in the tree branches above him and drops down smothering the fire. A man alone in the wilderness coupled with stupidity is a deadly combination. To deal with nature takes skill and know-how, this man seems to have neither, he was doomed from the moment he went off alone.(website) When it is 75 degrees below freezing one person doesnt have a second chance to build a fire. The temperature is just too cold and exposed parts of the body will start to freeze. The man still believes in his strength to overcome the power of nature and continues to try and build a fire. He doesnt succeed and at the end accepts his fate and falls asleep thinking about the next day when the boys would find him. The  story is an illustration of what can happen to a person that doesnt respect nature and its power. This is the story of a mans struggle against nature, trying to survive against impossible odds in a universe indifferent to an individuals fate.(909) The man was so confident in himself that he traveled with nothing but his lunch and a few matches and birch bark to start a fire. He has also been warned not to travel alone in such cold, but he goes anyway, with only his dog and confidence for a companion.(Synopsis, 220) He has no company, or supplies for the possibility he may confront some type of danger. Whether the danger be with another animal or with his surroundings. The short version of the story was originally published in the Boy Scouts of America Handbook. Any Boy Scout might remember the story form when they were a kid and the lessons that were taught from it when they were younger. They were taught to respect nature for what it is, what it can do, and of course, to always be prepared. If you arent, nature will take its toll, and what a deadly toll it can be.

The Press Between Freedom And Privacy Media Essay

The Press Between Freedom And Privacy Media Essay The freedom of press has been chronologically developed from the subjection to the rulers and governments to the supervision on them. What does this freedom add to the press? Many authors believed that this freedom increases the important role of the press in democratic societies. Press protects human rights against unjust rulers and builds background information for the people about the events that happen through the world. Other authors view the freedom of press as a destruction of people privacy life. In the previous decades, press was under the control of rulers and government. In Richard Andersons article Freedom of the Press ( June 23, 2008), Anderson reveals that critical speech or papers about governments were subject to punishment by the English law whether the critic was true or not since governments believe that any critic would affect the honesty and integrity of politics. When the democracy shined in the world, the press breathed a quiet sigh of relief as its freedom became possible. The democratic society is based on the variety of ideas and concepts related to social and political life. As citizens, people need to share and receive ideas among each other and they need to express it in different forms such as printing it. This is the main reason that made freedom of press or speech under the protection of human rights (Valeria, 2010), but what does the term freedom of press mean? According to European Unions Chart of Fundamental Right, the freedom of press is directly r elated to media liberty in gathering different information whereas according to Universal Declaration of Human Rights, the freedom of press is defined as broadcasting information in print form (as cited in Valeria, 2010). The freedom of the press is not only considered as an individual right but also as an institutional one. It is characterized by the right to publish and print information (Anderson, 2008). With this freedom, thousands of magazines and newspapers were established over the world covering different domains such as: political, social, sport, fashion, etc. The freedom of press constitutes one of the important components in the democratic society on which it represents a supervisor on the government, protects human rights, and builds knowledge for people about the outside world events. One of the important roles the press occupied is the inspection of the governments. In Baldings article Press Freedom: Every Citizens Right (February, 2007), Balding acknowledged that newspaper among other media types conserves its work as a supervisor on the government and on any violence action in the society. European Court of Human Rights stated that press let people know and judge ruler attitudes where it represents a watchdog on the political officers (Valeria, 2010). According to Stewart (1975, as cited in Anderson 2008), maintaining the political systems honesty and detecting any corruption in society are among the important roles of the press. When the politicians feel that they are inspected from public, they tend to complete their duties honestly. Any suspicious work or corrupted act by politician will be spotted by the press and broadcast to the public to take the right decision for such act. Hence press allows people sharing the government its role in managing the affair of the society and thus satisfies the principle of democracy: The people are the source of authority. Anderson (2010) states that the press has an important role in checking whether the criminal justice system is working properly or not. This can be achieved when the press attends the court to record the trial and broadcast it to the people to know the reliability of the judgment, thus consequently obliging the justice system to be fair. An example about this press role is what happened in 2001when Estada the president of Philippines was ousted by people after the press broadcasted his corruption where most of public was displeased from his policies such as the removal of sovereign guarantees on government contracts. This role can be extended to a stage where journalist can ask about authority and honesty of politics (Valeria, 2010) and as a result of this role, the press is known as the Fourth Estate. Another role the press played after attaining its freedom is the protection of human rights. Valeria (2010) demonstrates that an important role of press is the protection of humans rights such as protection against racial discrimination. Press always tries to protect rights of people since protecting them will protect the press itself. An important right the press works hardly to protect it is the freedom of expression since this right is the basic of its existence and according to Valeria (2010), freedom of expression consists of three main interdependent parts which are: the freedom of opinion, the freedom of information, and the freedom of press. Press also sheds the light on the violation of human rights that some governments do. In 2005, U.S made a war on Iraq under the cover of protecting Iraqs people right but the press showed the criminal act of U.S military against Iraq people. As a result, many journalists were killed under the cover of belonging to terrorist parties. Anoth er example that reveals the importance of press is the broadcasting of the discrimination that black peoples suffered in the American society which ended finally by equality between black and white people and present president of U.S.A is a black person. All this events prove the great role of press in protecting human rights. The final role the press got it after the announcement of its freedom is the informing of people about the outside world events. According to Douglas (n.d, as cited in Anderson 2008), press give the public the right to know the information that are important to us. The idea that the press was built on when it is constructed is the broadcasting of information and events that happened among the world. The press builds an intercommunication bridge between people of different countries because it shows them the events that happens inside or countries or in the neighbor ones. With the help of the press, people know the major and international problems that the world faces. For example after the industrial revolution, a lot of factories and pollutant machines have been invented leading to an increase in the emission of CO2. This excessive emission leads to the presence of the global warming phenomena. Without the presence of media and press, people would not know about this serious problem that threatens the nature. Moreover, press shed the light on this problem and imposes some awareness messages about this problem in addition to some solution that are proposed by experts. In 2004, when Tsunami happened in Indonesia, press had an important role in broadcasting this human disaster to the world viewing the big destruction that Indonesia and Indonesians have due to this event. In this case, press not only played a role in broadcasting international event but promoting humanitarian feelings of people toward each other. With the development of media and means of communications, world has became as a global village where all peoples can know the events that walks around them. This thing decreases the isolation among people and improves their background information in the world they are living in. On the other side, to insure that the press can inform people about events happening in the world, the journalists sources should be protected. In Valerias article Freedom of the Press A Component of Freedom of Expression (2010), European Court claims that protection of the sources of journalist is necessary so the informers can supply the journalists with the sufficient information they need to cover the events but this protection should not be unlimited. On the other hand, many authors reveal that freedom of press violated the privacy of people. In Zhendong Suns article Balancing Freedom of the press and the Right to Privacy: Lessons for China (February, 2006), Sun claims that press broke the right of privacy of individuals with the help of technology. Journalists gather information about people secretly without any knowledge of them and they gather and print private information of people under fake names. The laws that were written to protect the press freedom and the use of technology by journalists such as recording machines and cameras made the illegal interceptions of peoples private life by journalists easier. Some newspapers disseminates wrong facts about politicians or famous persons without any consideration to the effects of such act just to attract more readers and to have high income (Sun, 2006). It is right that press concern is to report matters that attract people, but this does not give them the right to search in peo ples private life to fulfill their goals. The program Where Are They Now?, gives specific details about the position of a person who were in the past a popular one ignoring the persons agreement about such an act (Sun,2006). Names and pictures of people have been used by press for commercial purposes and for advertisements (Sun, 2006). Furthermore, journalists today are lying on the interviewers to get their needs. In 1971, two journalists claimed that they need a medical advice from a sorcerer but they record his diagnosis and used the video as a evidence in the court to prohibit sorcery (Sun, 2006). It is true that the press freedom with the help of technology made journalists violate people privacy in some cases but it is unfair to consider that freedom of press cancelled the right of privacy of people. First of all, the court considered that a person that accepts to converse with others should be responsible about his conversation since they have the right to repeat what he said (Sun, 2006). In other words there is no illegality behind the actions of the two journalists mentioned before. Also, press has the right to search for the true to satisfy justice even if this requires the seeking of persons private life. For example, journalists are allowed to attend lawsuits in the courts although it is considered private to insure that the judgment is fair and that the judge is honest. In many cases, journalists search in people life to check their living situation and if they have problems so they can inform the government to solve it. One of the known programs that shed the light on people life problems is the Al-nashr program in Lebanon. This program goes deeply into the people private life and presents their problems to the public to help those who need help. Because of this program, more than 30 personal problems were solved by governments or by charities. Without this program, Lebanese government and citizens would never know about these Private problems and they will not be solved. This contradicts authors opinions that press cancelled people privacy. As a conclusion, the freedom of press is considered as an essential part in the democratic society. Schmidt (2007) demonstrates that the freedom of press constitutes one of the important components in democratic societies. It develops the society and the government, provides people with information, and improves the governments efficiency. Also, press protects human rights from being violated by governments such as freedom of expression and right of equality among peoples. In spite of these important roles that are occupied by press, some authors criticize the freedom of press as being breaks peoples privacy. Nowadays, the wide variety of media made the people have the full control on the way and on the time of receiving information and whether they like to interact or not (Balding, 2007). For the press to be as useful as possible it should be restricted to its duties, both legal and ethical and it should respect peoples equally important right (Sun, 2006).

Reading Nightmares :: essays papers

Reading Nightmares Reading nightmares exist at many different levels. There are nightmares at the national and state levels. There are nightmares within the field of reading education, and with teachers across all subject areas. This is a key point in the article â€Å"Exploring reading nightmares of middles and secondary school teachers† by William P. Bintz. At the national and state levels, research indicates that students experience a declining interest and slowing development in reading from the seventh grade on (Farr, Fay, Myers , & Ginsberg, 1987). They â€Å"demonstrate gains in reading during the early years, these gains seem to taper off in the middle and upper grades, and decline during the high school years.† (Chall 4) Many studies give strength to this argument that reading nightmares occur nationally. They show that students have difficulty with tasks requiring interpretations of what they read, that students do little, if any, reading in school and for homework, and that there is a decline in reading skills amongst 12th graders. (Bintz 13). Goodland (1984) believes that this problem may exist because of the relationship between time spent on reading instruction and the decline in reading abilities. He points out that â€Å"reading occupies only approximately 6% of class time in elementary school, 3% in junior High school, and 2% in senior high school. â€Å" (p 106-107). It is noted that 8th grade students watch TV, on average, almost 22 hours per week. They read for less than 2. (Humphrey 23). Reading instruction, as a field of study, is also ripe with nightmares. Too often, educators make assumptions about reading and its’ instruction. These include â€Å"(a) Reading instruction is primarily, if not exclusively, the role of elementary, not middle and secondary school teachers; and (b) reading is an isolated skill; once mastered in the elementary grades students require no further instruction.† (Bintz 14) As Burnett is keen to show, these attitudes are changing, but slowly. Teachers on the secondary level are still hesitant to get involved in reading instruction. They see themselves as teachers of content. But, perhaps, as Summers states, maybe the content area teachers are hesitant because they, along with many language arts teachers, aren’t properly trained to provide reading instruction. Regardless of content area, all teachers are seeing the same nightmares.

Discuss Charlotte Bronte’s portrayal of childhood in Jane Eyre. Essay

Discuss Charlotte Bronte’s portrayal of childhood in Jane Eyre. Charlotte Brontà «Ã¢â‚¬â„¢s ‘Jane Eyre’ was a controversial novel for its time. It traces the heroine from an orphan child to a contented adult woman. Through the trials Jane experiences Brontà « highlights many hypocritical aspects of Victorian society, mainly focusing on the religious hypocrisy of the era. Subtitled ‘An Autobiography’, the novel in parts closely resembles Brontà «Ã¢â‚¬â„¢s own childhood and her evocation of Jane’s experiences of Gateshead and Lowood remain as vivid as ever for the modern reader. Brontà « explores childhood feelings of hurt and loss, focusing on a solitary, suffering child. In these first nine chapters we see Jane at 'Gateshead', where she is the victim of unjust treatment within the Reed family (a 'poor relation'), and then at Lowood, the victim once more of a harsh, tyrannical and unjust regime (despite the good influences of Miss Temple). In these circumstances Jane is shown to be continually subject to harsh and unjust treatment. Yet the narration also establishes Jane as a passionate, emotional, potentially fiery, and morally clear-sighted: she has a strong will, and refuses to let injustice and hypocrisy go by. She comments that ‘conventionality is not morality’. However this unusual and uncontrollable passion in a little girl is abhorred in Victorian society, it goes against the doctrine that states ‘children should be seen and not heard.’ Bessie exclaims ‘Did anybody ever see such a picture of passion!’ when Jane attacks Master Reed. She is often described by the Reed household as an animal: ‘you rat!’; ‘Hold her arms Miss Abbot: she’s like a mad cat.’ She is lowly regarded within the household, they wish she c... ...es represented by Mrs. Reed and Mr Brocklehurst is shown most clearly in the character of Helen Burns, who is most clearly a product of their propagandizing on humility and self-denial. Although Jane respects Helen’s honesty and stoicism, she cannot understand her beliefs and the way in which she accepts her constant chastisement so submissively; she herself ‘should wish the earth to open and swallow me up.’ After talking to Helen, Jane comments that her feelings were ‘better regulated’ and ‘thoughts more harmonious.’ Finally in Mrs. Temple Jane finds someone whom she can respect and admire; a role model. Helen observes that ‘Miss. Temple is full of goodness; it pains her to be severe to anyone.’ The portrayal of Childhood in this novel is utterly convincing and illustrates the triumph of a child’s spirit in spite of difficult circumstances very well.

Blood clots Essay

Blood clots are also known as the thrombus which is the result of blood coagulation step in hemostasis. Blood clots are formed through platelets’ aggression which makes a platelet plug and the stimulation of the humoral coagulation system. Blood clots noted as a pathologic in terms of thrombosis but then it is physiologic in terms of injury. Thrombus signifies blood clotting in the intact blood vessels. It is a big blood vessel that reduces blood flow via that vessel. Moreover, in the case of small blood vessel, the blood movement might totally stop which may cause death of tissue which provided by the said vessel. If the thrombus extricates and turns out to be free-floating, it becomes an embolus. There are several conditions in which blood clots form which involve atrial fibrillation which is a cardiac arrhythmia’s formation, heart valve replacement, extension periods of inactivity, a previous heart attack and genetic inadequacies (see â€Å"Thrombus†. Wikipedia, the free encyclopedia. October 11, 2006). Blood clots’ preventions may decrease the possibility of pulmonary embolism, heart attack and stroke. Warfarin and heparin are frequently used to slow and restrain formation and progress of prevailing blood clots which permit our body to decrease and suspend the blood clots by means of usual methods. A thrombus is distinct from haematoma by means of: >being non-laminar >being elastic and brittle > has a high haematocrit >lacks of circulation (see â€Å"Thrombus†. Wikipedia, the free encyclopedia. October 11, 2006). The purposes of this study are to: (1) know what blood clots are; (2) be aware on how blood clots do form and; (3) learn how blood clots treated. II. Discussion A. About Blood Clots If the blood vessels are destroyed, the lack of blood from the system should be suspended before â€Å"shock† occurs and may possibly leads patient’s death. It is achieved through the blood’s solidification and the said process is termed as coagulation or clotting. Blood clots comprise of a plug of platelets entangled in a group of insoluble fibrin molecules (see â€Å"Blood Clotting†. June 4, 2005). Moreover, blood clots are the misery and pest of the existence of human beings. The can create strokes and heart attacks and they suspend blood supply to an individual’s legs. Many physicians denote this process as thrombosis. Several scientists have extensive researched for a period of time regarding the vascular biology which has an intention to stop thrombosis and cure its consequences yet it continuously serves as a culprit for death causes. Approximately in the past five years, the Mayo cardiovascular researchers continually widened their investigations regarding the vascular biology after they found out that thrombosis formed through interaction of cells exist in the vessel wall and in the circulation of the bloodstream. Dr. Simari stated that: â€Å"The major focus of our lab is to understand the biological process that narrows blood vessels, both in arthrosclerosis and in re- stenosis. Our aim is to take the biological clues that we learn from our research and use them to generate biological markers and treatments that can predict, prevent and treat thrombosis at the site of vascular injury (see â€Å"The Biology of Blood Clots†. Mayo Clinic’s Online Research Magazine. 2006). In addition, the blood clots develop even if an individual does not experience injury. Even though majority of the blood clots have a tendency to suspend, there are circumstances in which blood clots can create medical dilemmas. Blood clots turn out to be risky if they block blood movement via artery or vein. If the blood clot prevents or deters the blood movement to an artery in the brain or heart, it may lead to stroke or heart attack. Blood clots can deter, too, the veins and arteries in our entire body which cause illnesses like varicose veins to serious pulmonary embolism. The picture below illustrates the formation of blood clot (see â€Å"Blood Clots†. HeartCenterOnline. May 9, 2006). B. How blood clots do form? The cells which line inside the layer of blood vessel becomes injured which is instigated by a wound. The blood platelets automatically go directly to the injured area and connect themselves with the intention to close of the wound. Look at the picture below (see â€Å"How do blood clots form? March 11, 2004). Platelets clump together and the clothing process begins The platelets discharge a chemical substance which draw and bring together more platelets to the injured area. In the meantime, other substances are mix with platelets to create and develop a blood clot. This process is named as coagulation. Fibrin is released. Fibrin describes as a thread-like protein which aids the stabilization of the clot in the blood vessel. The picture below shows how blood clot forms and fibrin stabilizes clot (see â€Å"How do blood clots form? March 11, 2004). Additionally, blood clot can be developed too through gradual increase of plaque inside the artery-an example for this is the atherosclerosis- or other illnesses. Any vein or artery may possibly experience and form blood clots inside our body which include the coronary arteries that provide the heart with blood, the arteries which provide the brain with blood-an example for this is the carotid arteries, and the veins in the legs. As mentioned earlier, blood clots can also be dangerous if will it develop inside in any of these arteries: ? The pulmonary artery passes through from the heart to the lungs. Obstruction in this artery is named as a pulmonary embolism and may create a great damage in the lungs and in several circumstances, may lead to death. This is because of the abnormal heart pulse which is termed as atrial fibrillation or through a peripheral venous disorder inside the veins of the legs-an example is the deep vein thrombosis. ? One of the coronary arteries that can be found on the heart’s surface and provide the heart muscle with new, oxygen-rich blood. The obstruction of the coronary arteries may possibly cause a heart attack. In this condition, blood clots normally develop as a reaction to the plaque rupture that happens if a plaque piles up inside the coronary artery fractures’ wall, which initiate blood clotting. ? The carotid arteries that is located in the neck and provide the brain with oxygen-rich blood. Obstruction may possibly initiate a stroke-an example for this is the transient ischemic attack. ? The femoral artery which is located in the leg. Obstruction may instigate pain like claudication, absence of color’s area, weakness and when this is not cured, infection like gangrene and tissue death like necrosis. An artery can be located in the abdomen. Obstruction may create diarrhea, vomiting or pain (â€Å"Blood Clots†. HeartCenterOnline. May 9, 2006). C. how blood clots treated Several physicians cure blood clots with several procedures. Treatments like anticoagulants that aid to prevent blood clots and clot busters that aid to suspend blood clots. In some serious circumstances, physicians may possibly decide to use for a catheter-based procedure which utilize a long, thin tube named as catheter or even decide for a surgery to take off the clot-thrombectomy. Moreover, there are maybe devices that need to be implanted in particular blood vessels in order to catch blood clots before there will be more injury happened (see â€Å"Blood Clots†. HeartCenterOnline. May 9, 2006). C. 1 Treatment options for blood clots The option in treating blood clots is a case to case basis whether the clot has developed in an artery or a vein and creates stroke or heart attack. During emergencies, thrombolytic treatments-clot busters- may possibly used to suspend the blood clot. These treatments are applied to some selected patients in accordance to an extensive protocol. In order to be efficient, they are provided no less than one hour of the heart attack or in three hours of the stroke. Thrombolytics are normally applied when there are huge clots which cause severe and life-threatening signs. These can create abrupt and unexpected bleeding. There are many invasive methods that can also be used. One of these is the catheter-directed thrombolysis. It is a method which the catheter procvides thrombolytic enzymes straight to the blood clot. Throughout this process, greater enzymes’ concentrations could be utilized and may possibly have lesser side effects compared when the enzymes are supplied subcutaneously no less than two days. Thrombolytic method is followed by a treatment that has anticoagulants to stop more blood clots from formation. Anticoagulants could be advised to patients that have great risk of a blood clot. Researchers are really trying very hard to different catheter-based procedures to cure stroke rapidly. One of the experimental procedures which included is the use of a tiny â€Å"corkscrew† device which rapidly reverses the injury created by a stroke. The said device is directed to where the blood clot is; where it removes the obstruction. Another procedure depends on a special laser catheter which utilizes light energy to suspend rapidly the blood clot. These latest therapies can be accessible to a patient that cannot bear clot-busting drugs (see â€Å"Treatment options for blood. † Blood Clot, HeartCenterOnline. May 9, 2006). Furthermore, when a blood clot develops in a leg vein, there is a risk that a pulmonary embolism will form. A pulmonary embolism may possibly be a life-threatening in which blood clots break away from its location and passes through the bloodstream and stay in one of the blood vessels of the lungs. To avoid and stop a pulmonary embolism, the present blood clots in the legs may cured with a mixture of heat, thrombolytics, painkilling treatments, elevation of the injured area to lessen swelling and anticoagulants. This procedure relies on the clot’s size and the seriousness of any current symptoms. When a patient does not react to anticoagulants, the physicians will decide for a process which uses a catheter having a special device named as vena cava filter. The vena cava filter is inserted in the large vein which transports blood from the legs up to the heart and lungs (vena cava). Additionally, the vena cava filter is a kind of a device which catches blood clots within the vein before the blood clots are permitted to reach the lungs. However, there are several danger related with vena cava filters which comprise failure of the filter in terms of time and blood clots created by means of it. Many researchers really work on in improving the vena cava filters which can be withdrawn right after the medication of pulmonary embolism. There are researches that substantiated and confirmed that treatment in a longer period of time along with a low-does anticoagulant drugs aids in stopping the presence of blood clots amongst those patients who have background of vein thrombosis or pulmonary embolism (see â€Å"Treatment options for blood. † Blood Clot, HeartCenterOnline. May 9, 2006). C. 2 Diagnosis methods There are several ways on how to diagnose blood clots. It starts with a medical background and physical test. When there is suspension of clot, several of examinations are utilized to substantiate the diagnosis and these include Doppler ultrasound, CAT scan and MRI: *Doppler ultrasound pertains to an imaging technology which utilizes sound or motion waves to give visual images of the structure and of several blood vessels and organs in our body (see â€Å"Diagnosis methods for blood clots†. Blood clots, HeartCenterOnline. May 9, 2006). * CAT scan refers to computer axial tomography. It is an examination which utilizes a number of x-rays which got from different sides in order to give a computerized three-dimensional image of a body shape (see â€Å"Diagnosis methods for blood clots†. Blood clots, HeartCenterOnline. May 9, 2006). *MRI means magnetic resonance imaging which is a noninvasive examination that utilizes magnetic fields to give high-resolution cross- sectional or three-dimensional visual images of the aimed surface (see â€Å"Diagnosis methods for blood clots†.
