Metals and corronslon - Lab Report Example Metals react with acids to give the metal salt and water. The purpose of this experiment is the determination of the different properties of metals. The properties determined include conductivity, hardiness, and Brittleness. Also, the ability of copper, iron and brass to resist corrosion was investigated in this experiment. All the three metals were placed in three different open beakers containing tap water and left there for 3 days. After the tree days, it the changes in the physical appearance of the metal was observed and recorded When one end of the three metals were heated and time taken for the heat to be transfred from the end being heated to the other opposite end taken, it was found that it was faster in copper than in iron and brass. From the experiment, it can be determined that iron and brass are prone to corrosion as compared to copper. Also, comparison of the brittleness of the three indicates that iron is more brittle as compared to copper and brass. The alloy of copper and iron, brass is harder than the pure metals. From the experiment, it can be concluded that copper metal is a good conductor of heat, iron is more brittle and brass is harder. Also, it can be conclude that, substances containing iron are more prone to corrosion as compared to substance lacking iron. This due to the presence of iron II Oxide that is converted to iron III Oxide which is the rust that causes

Liberal Democracy Coursework Example | Topics and Well Written Essays - 750 words

Liberal Democracy - Coursework Example Statutory laws and controlled institutions are relied upon to guarantee the liberal and constitutional rights of the citizens (Kukathas 2004, p. 45). According to Held (2006, p.73), liberal democracy is well supported by the political theory of pluralism, which allows individuals and groups reach for their interests in the political process, hence, decisions are arrived at through compromise to accommodate the interests of all stakeholders and interest groups. One of the main elements of a liberal democracy is the constitution. The constitution in liberal democracies starts with the assumption of sovereignty, vesting the ultimate power in the people. The democracy presupposes that people can control their destiny and that they make moral judgments and practical decisions in their daily lives (Wallace 2007 pg. 7). It requires a decision-making system based on majority rule, with the protection of minority rights; seeks to protect in  judgments while controlling the majority (majoritarianism) by trying to face out the practice of majority rule (Dunn 1994, pg 11). The constitutions of liberal democracies mostly uphold the four main concepts of democratic creed namely: individualism, liberty, equality and fraternity. Individualism states that the prime objective of democratic government is to protect citizens so that each individual in the state can achieve the highest level of personal development (Marlman 2009, pg13). Liberty is in essence allowing individuals the highest degree of freedom that is consistent with order and natural justice. Equality states and maintains that all people are equal in creation have equal opportunities and rights (Mueller 2007, p.41).  

Illegal Immigration in America Essay Example | Topics and Well Written Essays - 1000 words

Illegal Immigration in America - Essay Example Throughout most of American history, America has portrayed an existence of invasion, and has stepped foot into almost every battlefield and continent in the world. Taking this aggressive stance towards diplomacy, America should not be able to forget its past, and say that after destroying so much land and taking over so many peoples, it is now not going to let immigration happen. After all, this country was built on immigrants, and to not allow immigrants into this country is simply against all past policies of the United States. To invade so many lands, and then turn the other check and not allow other people into our own country is hypocrisy, and should not be the stance America takes. Even at the start of our own history, Americans looked towards the West. The idea of Manifest Destiny grew up in popular opinion, and people began to push the boundaries of the United States further and further West. This feeling of territorial claim that the United States has to the rest of the fron tier was used to justify many of our territorial expansions. Manifest Destiny "has also been used to advocate for or justify other territorial acquisitions. Advocates of Manifest Destiny believed that expansion was not only good, but that it was obvious ("manifest") and certain ("destiny")" (Manifest, 2007). This idea is still relevant today, when people feel that America has the right, or even the calling to police other areas of the world. However, America tends to expand without thinking or care towards the native people of the land. When America was first being colonized for example, some historians estimate that up to 80% of some Native populations died due to European diseases"(Native, 2007). This apparent lack of disregard continued through American history, as we took over Native American lands and put them on reservations, all trying to further expand our power. But now, when other peoples look to move into this country, we are not allowing them to do so. Even if this country was one taken on behalf of other people. As America continued to grow, so did its outward policies of getting involved in other countries. However, today we will not return the favor by allowing other counties to send their immigrants to our land. For instance, in 1989 the United States intruded upon Panama, disposing a leader we did not approve of. The United States "incursion into Panama began on December 20, 1989, at 0100 local time. The operation involved 27,684 U.S. troops and over 300 aircraft -including the AC-130 Spectre gunship, OA-37B Dragonfly observation and attack aircraft, and the F-117A Nighthawk stealth aircraft and AH-64 Apache attack helicopter, the AH-64 and the F-117A both seeing their first combat deployment. These were deployed against the 16,000 members of the Panama Defense Force" (United,2007). We also set up a new President, a President we approved of. However, we were really justified in taking action in this region Or was the 'father' idea of the United States getting the best of us Either way, i f we were to invade a country, one would think that we would then allow immigrants from that country. However, one can see today that that is not the case, and that America is

Aboriginal land rights in Australia Research Proposal

Aboriginal land rights in Australia - Research Proposal Example o Aborigines, Diane Bell has boldly expressed it as a sign that there is a drastic alteration in the legal and administrative stance to the acknowledgment of Aboriginal rights in Australia. Bell further justified her claims through pronouncing these statements;"Nowhere are these changes as striking as in the struggle of the Aboriginal people to gain recognition of land rights. This struggle has involved both moral and legal re-examinations of the relationship between a settler population and the original inhabitants. The wording of the Land Rights Act Northern Territory (1976) and the reference to customary law both assume that Aborigines have rights and a system of law, and that these have existed for many thousands of years. Such propositions would have been unthinkable two hundred years ago, when Australia was settled as a British colony. Not only has the legal profession had to rethink its judgments and governments to legislate to recognize aspects of Aboriginal Rights, but th e Aborigines themselves have organized locally and nationally to bring the grievances and the injustices suffered by their people to the attention of other Australians and to people abroad."1 Nevertheless, there are alarming difficulties regarding the debate on land rights. The issue has branched out extensively to include political implications which made it extremely complicated to represent objectively and impartially. In a scholarly matter, it is rather inappropriate to provide an in-depth analysis of the causes of the land rights battle while it is still being fought. Neutrality of opinion regarding a politically charged state of affairs can be then argued as an indication of support to the conservative racist forces in Australia which combat the bestowing of land rights to the original inhabitants of Australia. Nonetheless, there is an urgent need to expose and investigate the issues revolving around the land rights movement since arguments and raison d''tre on both sides of the problem are dreadfully ambiguous. A tranquil and balanced evaluation of the diverse issues of the land rights movement can possibly generate a remedial and enlightening effect and conceivably guide those who are fervently faithful to the land rights proposal to come up with a persuasive way in presenting their case. Many Australians advocate the recognition of the Aborigine's traditional land rights which constitute the right to utilize and subsist on the land that they have previously occupied. The supporters of the land rights movement give their best hopes that a greater recognition of these customary rights, which is termed as the native title, would smooth the progress of compromise between Aborigines and white Australians. However, the land claims of the Aborigines demonstrate composite legal concerns, such as the problems that granting of native titles will cause to private welfare in the land that have existed in Australia over the past two decades. The complex issue over land rights necessitates the vitality of confronting the problem with the deep-seated legal principles regarding land rights of aboriginal people. The Land Rights Movement In the 1960s, the Aboriginal land rights movement inaugurated its emergence as a "movement", as such. The term "movement" is quite an inappropriate word to use since the

Critique a TV or radio commercial, an Internet advertisement, or a print for Gastroesphageal (Gerd) use Nexium for the medication - Essay Example This disease is affecting more and more individuals each day, including very young children. This paper investigates two kinds of treatment for GERD, one is FDA-approved and the other is not. Looking at their advertisements and reports of use online, the paper determines which treatment is better for patients with GERD. GERD is becoming more and more common nowadays and what was once thought as a simple nuisance related to eating has now been recognized as a disease (Maranto, 2001). GERD is characterized by acid reflux coming from the stomach and reaching the esophagus, causing the patient to vomit, feel uneasy, suffer from chronic cough, laryngitis, abdominal pain, dysphagia, anemia, weight loss, or even asthma. There are some cases where the patient even experienced heartburn (FDA, 2008), making the symptoms quite vague to determine. Some experience reflux after eating a large meal or enjoying their favourite dish. This led to the belief that GERD is triggered by some food ingredients. Still others thought the disease is caused by overeating, thus they watched their diet but still experienced the same problem. Although the main cause of GERD was not yet revealed, experts have made different solutions to remedy the problem. On the conservative side, people were asked to watch their diet, eat nutritious food, and avoid stress. However, others were prescribed to undergo surgery, which did not help as patients experienced more problems later on, including cancer of the esophagus (Tygat, 2002). Experts have yielded to the belief that surgery is least required; therefore resorting to medical treatments. The two treatments investigated in the paper are Nexium and Betaine Hydrocloride (Hcl) with Pepsin. Approved for drug use by the FDA for the treatment of GERD including young children age 1-11 years (â€Å"Nexium†, 2008), Nexium is composed of esomeprazole magnesium in liquid and capsule form. It is manufactured by

While the third world countries are trying to create their defense stronger to protect themselves from the foreign invasion, and so are trying to spend every dime on the procurement of deadliest weapons they can lay their hands on. As the former U.S. President, Dwight D. Eisenhower, so rightly put the whole situation, in a speech on April 16, 1953, by saying â€Å"every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed.
