Exploding Mentos Drink

Exploding Mentos Drink A friend sent me a link to a Wired how-to project called The Manhattan Project in which you freeze a Mentos candy into an ice cube and place it in a carbonated drink. When the ice cube melts, the wax surrounding the candy will be exposed and the drink should erupt. Does it work? Lets find out. Exploding Mentos Drink Ingredients The drink in the original recipe called for whiskey, sweet vermouth, and bitters (basically a Manhattan plus diet cola), but you can make a rum and coke or whatever you like or just try the non-alcoholic version using two ingredients: diet colaa Mentosâ„ ¢ candy Make the Exploding Drink Ill tell you right up front: a drink with soda and Mentos wont explode unless it is in an enclosed container. Exploding drinks make messes, plus they tend to spray out shards of glass, so its a good thing this drink isnt so violent. Erupting is more what youre looking for here. If you want to cause an unexpected eruption, freeze a single Mentos candy into the well of an ice cube tray. Youll get the best results if you wait until the ice is almost frozen and then add a Mentos candy to each cube so that its near the surface of the ice. You dont want to soak the candy in cold water or its coating will dissolve. If that happens, all youll get when you mix it with diet cola is candy-flavored cola. The premise is that the Mentos will become exposed as the ice cube melts. When the wax coating of the candy reacts with the diet soda, the drink will fizz and bubble like the classic Mentos and diet soda fountain. If youre doing the project on-purpose or else dont mind getting caught dropping a Mentos into someones carbonated drink, you can simply plop the candy in the soda no ice cube needed. How the Mentos in Ice Cubes Trick Works Among other things, the gum arabic that coats a Mentos candy lowers the surface tension of the soda, allowing carbon dioxide bubbles to rise and expand more easily. The candy coating traps the gas, forming bubbles and foam. When I tried this project, I didnt get a spectacular eruption, but you can expect somewhat better results if you use a narrow glass for your drink. Except that the Mentos flavors the drink, I dont think someone with a Mentos-laced ice cube would notice much happening or suffer from an out-of-control foaming drink. The project is still pretty fun.

Biomedical Issues in Autism Speech or Presentation

Biomedical Issues in Autism - Speech or Presentation Example Of special interest is the toxicological perspective which is, to some extent, also related to environmental factors. One important aspect is the role of environmental toxicities that can initiate or aggravate autistic symptoms in predisposed individuals. Etiologically speaking, certain metabolic abnormalities have been blamed to play a central role towards development of autism. This is manifested by the increased incidence of inflammatory disorders of the gastrointestinal system noted in autistic children. Such metabolic differences have been investigated in various studies, and it has been suggested that it is highly likely that other metabolic inefficiencies of this type render autistic individuals unable to cope with toxicities prevailing in the immediate environment of such individuals. These disorders of metabolism, therefore, contribute towards the development of autism in individuals by limiting their ability to overcome the metabolic challenges posed by the environmental to xicities. A major toxicity that has been studied in this regard is the presence of excess amounts of mercury in the environment of those who develop this condition. Review of Current Literature Although mercury is considered to be present in trace amounts in our environment, there are points in the mercury cycle where its interaction with life forms becomes significant enough to be considered as a contributor of disease. Once it is converted into methylmercury, it becomes volatile and soluble enough to get bio-accumulated in food chains (Utah.Gov). Mercury has been identified to be a neuro-toxin, and causes defects in memory, cognitive thinking, language, visual ability, and motor skills. These manifestations are more marked in developing brains. Common sources of exposure to mercury include food (fish etc.), dental amalgam, batteries, coal, and medical products including vaccines. There have been heated debates about the link between mercury and autism, and it appears that the vast majority of studies which deny such linkage are carried out under the influence of those who have a vested interest in promoting the concept of mercury being safe for human consumption. The reason for this claim is the fact that sufficient evidence exists to support a link between the two (DeSoto and Robert 165). Studies conducted to evaluate the level of mercury in hair and nail samples of autistic individuals have also pointed out that mercury can possibly act as a causative or contributive factor. The level of mercury in these tissues is considerably higher in autistic individuals as compared to their healthy counterparts (Priya and Arumugam 148). The notion that altered metabolic processes contribute towards the pathogenesis of autism due to mercury poisoning has been supported by research work. Of considerable importance is the observation that adverse reactions and abnormal development in autistic individuals correlate closely to their exposure to vaccines containing mercury as their constituent element. Higher levels of mercury in autistic individuals may be attributed to a different or defective pattern of metabolism in these individuals (Majewska et al. 196). Studies designed to seek a relationship between elevated levels of mercury in blood and the presence of autism have found a positive

Review performance about "Next to the Normal" Essay

Review performance about "Next to the Normal" - Essay Example Next to Normal takes one through an exhilarating journey of laughter and sorrow as one relates with the challenges of the actors (Brantley, 2009). Diana Goodman is a loving wife and mother who want the best out of her largely dysfunctional family. Their struggles typify the normal suburban neighborhood in an emotional manner, and the actors punctuate this with periodic musical breaks. In addition, Goodman has bipolar disorder, a form of mental illness, which affects the normal functioning of her already disunited family. The plot also explores Natalie’s drug abuse and her isolation from the family. The music and stage decoration is perfect. Through a lively pop/rock score, this intensely moving piece of theatre offers a breathtaking opportunity for the actors to investigate dramatic material and highlight their vocal talents. The timing of the lighting effects is in lieu with the message in the storyline and depicts the right emotion. As the musical starts, the lights go off and reveal Diana Goodman sitting alone, pondering about her future. Similarly, as the musical ends, Natalie, the daughter, walks in and turns on the light when he finds his father seated in darkness. She turns on all the lights in the house and reveals Diana who is visibly hurt, but happy to be alive. Apart from the lighting, the scenic and sound design augments the direction and mood of the musical performed on a three-story set that doubles as a doctor’s office, residence, and school. The actors and actresses do an excellent job in their performance. This is fortified by the numerous applauds and awards the musical has won as it endears itself to the public. Drama Desk Awards awarded Alice Ripley for Outstanding Actress in the musical. Of the eleven nominations in the 2009 Tony Awards, the musical won three, including Best Performance by a Leading Actress in a Musical for Alice Ripley. Similarly, Aaron Tveit won Most Promising

United States Economic and Foreign Policies Towards Latin America Essay Example for Free

United States Economic and Foreign Policies Towards Latin America Essay United States and Latin America need each other by the virtue of sharing common boundary hence the importance of the economic policies which favor these countries for mutual benefit. Latin America is one of the United State export market, for example in 1992 export exceeded $ 100 billion to this region . According to Fryer 1993, Latin American economic association with United States resulted to negative effect. Latin America eternal debts in 1992 was approximately $330 billion United States lending institution getting the largest amount of monthly servicing of this debt about 2 percent . This resulted to Latin American contributing to deficit in the United State budget hence the importance of better economic and foreign policy for mutual benefit . Latin America due to it geographical position to United States is inextricably dependent on the United States economy and on the other hand United States economy benefit a lot from trade. After accusation of neglect of Latin America, United States authorities have changed tune time of cold war perception that Latin America was a threat to an important economic partner . United States and Latin America have been having historical imbalances economically and in foreign policies. Overtime, policies to change this trend have been put in place due to realization that these countries are important to United States equally like northern partners (Vasquez). This means, policies favoring healthy relationship designed by United States would help in ensuring these countries enjoy mutual benefit. To Latin American, Economic and foreign policies are important since they are dependent of the United States economy. If the economic well being of United States is affected for example by recession this duplicates to their economies. Relationship of most government from south and United States economic policies has been unhealthy characterized by opposition to various policies. In the history, Latin countries foreign policies have been designed in opposition to the United States policies . This is due to United States authorities trying to interfere and meddling with the internal affair of these countries. A good example to this is the influence which Russia was able to influence most of the Latin Government to adopt communism policies against United States capitalism policies. According to Rabe 1988, Latin Americans in history have bitter to various United States policies mostly economic and foreign. A good example to this argument is the episode which transpired to Vice President Nixon being stoned in May 1958 in his tour to South America in attempt to smug confidence on foreign and economic policies . This was under leadership of Eisenhower and his foreign and economic policies of anti-communism. In 50s and 60s, Southern economy was growing in a sluggish manner since price of produce from these countries continued to decay yet United State imported 70 percent of their produce . United States showed no interest in stabilizing prices making Latin American countries to suffer economically. This made the socialism ideology to take centre stage in the policies of most of Latin American country protesting against U. S economic and foreign policies. This resulted to counter policies by United States against the communism and economic sanction which harmed economic status of southern countries. This trend continued to the cold war period until fall of Soviet Union and it communism policies. Current foreign and economic policies toward Latin America have been designed to amend bitter past relationship and forge for healthy foreign and economic policies for mutual benefit. There has been a major progress since the collapse of the Berlin wall in 1989, hence falls of Soviet union resulting to change of various administrative policies in South America. From 1990, Latin America has experienced major changes which include giving way to democratic governance, adoption of free market economy model, regulating on protectionism policies, giving way to privatization and adjusting on their trade regime. This gave way to future relationship of United States which was initially forged by former President George Bush, under Enterprise for the Americas Initiative umbrella. This was marking end to U. S. cold war policies which were obstacle to social, political and economic progress in Latin America countries . United States foreign policies employed to third world countries since cold war period are confrontation or engagement. Allies of U. S. have been subjected to engagement policy which meant that, they would get economic and military support. On the other hand, they were expected to adopt an environment favorable to United States policies . On the Latin America, United State has been persuading Latin American countries toward the policy of engagement without a major success hence subjecting these countries to U. S foreign policy of confrontation. Policy of confrontation was employed to countries against U. S policies of capitalism and interests. United States use it economic, military as well as political mighty to convert countries to support their interests during cold war period. This policy was employed to Latin America although in most instances it failed . Turn around of the U. S relationship with Latin America has resulted to Latin countries embracing American economic policies. For example Mexico has been in fore front of Latin America region in ditching inefficient protectionism polices, adopting privatization, debt reduction and foreign investment all which are under United States economic policies for south. United States economic policies have shown major effect in Mexico with North American Free Trade Agreement (NAFTA) helping this country to economic reformation. Mexico approval by NAFT is a major test for post cold war relationship among Latin American countries and success of failure having a direct impact to rest of the Southerners . United States economic policies on free trade advised to be employed in Latin America and in operation in Mexico does not automatic translates to a well-distributed economic growth overnight. Also, it does not convert ailing economies as it is purported to be. Latin American economy is comprised of very little wealthy class of people consisting of ruling elite. Their middle categories of people consist of very few individuals with the majority of the population living in poverty like any other third world countries . United States trying to duplicating its economic policies to Latin America may be misplaced due to the fact that if wealth distribution structure is different from that of third world countries. This gets us to quagmire of whether the economic policies advanced by Unites States to Latin America can reduce current economic injustice . Some scholars have for argued that the policy of laissez faire capitalism results to wide gap between poor and rich in the community, questioning rationality of employing it in Latin America . There is a contradiction of capitalism and socialist theory not able to give the right answer to the eradication of poverty in the third world countries economies. Communism tried to employed idea of supporting every one towards equality by ignored the human fundamental drive i. e. incentive system which have been key to economic growth under capitalism economic policies . On the other hand, capitalism policies and liberalization of the economy which a key economic policies advanced by U. S. to Latin America may fail. For example opening up market by Australian Authority resulted to loss of employment and fall of production sector resulting to increased imports against export. This gets to the question whether this may duplicate to the economies of Latin America countries since case of western capitalism contains it own contradiction. Various studies indicate that unregulated markets lead to economic exploitation and injustice which may be experience in Latin American after adopting U. S. economic policies. If the economic policies advanced by United States to Latin America fail, bitter rivalry which has been in existence before the cold war might escalate again and blame game of United States sabotaging Latin America economy may be renewed . To ensure United States economic and foreign policies succeed on Latin America, policies geared toward bridging the economic diversity within this region are important. This is because some countries have adopted the United States economic policies while others are about or implementing them. For example Mexico and Chile economic policy implementation has lead to economic growth . On the other hand countries like Argentina are not yet stable economically stable. Argentina recorded economic deterioration in 2000 and 2001. For Latin America to benefit from United States economic and foreign policies there should be a defined categorization according to economic differences since needs may be different . Economic policies to nurture growth of private sector and improve productivity are of great importance. These policies lead to enhanced economic growth, a right answer to poverty eradication in Southern hemisphere. United state economic and foreign policies should put emphasis on productivity through partnering with institution like Inter-American Development Bank (IDB) and other financial partners . This will be inconsistent with President Bush policies i. e. investing in people, ruling justly and opening doors for economic freedom. Meaning that a major emphasis on development of human capital through improving education system and employment of new technologies for high productivity. Ruling justly help attaining of increased productivity as corruption and protection of contracts may attract private investment which is key to increased productivity. Therefore, United States economic policies should focus on the area of productivity and apply it categorically according to economic needs of different Latin American countries.

Nuclear Energy :: essays research papers

Nuclear Energy Radioactive wastes, must for the protection of mankind be stored or disposed in such a manner that isolation from the biosphere is assured until they have decayed to innocuous levels. If this is not done, the world could face severe physical problems to living species living on this planet. Some atoms can disintegrate spontaneously. As they do, they emit ionizing radiation. Atoms having this property are called radioactive. By far the greatest number of uses for radioactivity in Canada relate not to the fission, but to the decay of radioactive materials - radioisotopes. These are unstable atoms that emit energy for a period of time that varies with the isotope. During this active period, while the atoms are 'decaying' to a stable state their energies can be used according to the kind of energy they emit. Since the mid 1900's radioactive wastes have been stored in different manners, but since several years new ways of disposing and storing these wastes have been develop ed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the borosilicate: any of several salts derived from both boric acid and silicic acid and found in certain minerals such as tourmaline. additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These operations are carried out in a metallic pot that is heated in an induction furnace. The vitrification of one load of wastes comprises of the following stages. The first step is 'Feeding'. In this step the vitrification receives a constant flow of mixture of wastes and of additives until it is 80% full of calcine. The feeding rate and heating power are adjusted so that an aqueous phase of several litres is permanently maintained at the surface of th e pot. The second step is the 'Calcination and glass evaporation'. In this step when the pot is practically full of calcine, the temperature is progressively increased up to 1100 to 1500 C and then is maintained for several hours so to allow the glass to elaborate. The third step is 'Glass casting'. The glass is cast in a special container. The heating of the output of the vitrification pot causes the glass plug to melt, thus allowing the glass to flow into containers which are then transferred into the storage.

American Aid Policy

The United States is the leading developed nation in foreign aid that considers both the interest of its own citizens and industries and those of beneficiary countries. Billions of people all over the world have benefited and appreciated the role of United States in both foreign and food aid. This research paper looks deeply into the overall effectiveness of US foreign aid policy, the need to effect any changes in policy framework or continue to handle affairs in their current form and finally examine the need to increase or decrease the amount in foreign aid.Aid and Millennium Development Goals The achievement of the Millennium Development Goals in third world countries and specifically the African continent cannot be realized when foreign aid to these nations is not fully availed. Human development has been ignored by international donor community notably the World Bank and the International Monetary Fund, instead putting more focus on biased economic parameters. Poverty levels in these nations thus cannot be eradicated. Africa alone needs a total of 72 billion dollars in foreign aid per year to achieve its Millennium Development Goals by 2015.This is meager fraction in comparison to the $ 362 billion in subsidiaries developed countries paid to its home based agricultural sectors in 2006. Commitment by developed countries to increase amounts in foreign aid to 0. 7% of their national income has not been realized (Marr, Gunatilaka & Killick, 1998). United States has faired poorly in its rating with only 0. 16% and appears at the bottom of the list. Eradicating poverty and improving human life demand increase in foreign aid to developing nations and failure to honor these commitments means that the present status in terms of poverty levels will remain for a long time.Effectiveness of Foreign Aid The close relationship that exists between foreign aid effectiveness and conditions attached to it has always been a thorny issue. Important development agendas such as the balancing of existing relationship between recipient and donor, considering first support to priorities sectors by the government, deter cases of aid programmes duplications and providing means for undertaking transparency assessment on aid performance are factors that must be put into consideration to ensure aid effectiveness.Furthermore, donor support harmonization in aid programmes that undertake development projects in more than one country demands mutual accountability. Direct budget subsidy contributed by donor countries which still stands at 5% of aid given to developing nations should be viewed by the recipient countries as domestic; hence, implemented vividly on development agendas rather than being accountable to the donors.Though this may be the best way of implementing aid as it create an opportunity for strong economic principles and political willingness to avoid bureaucracy, donors do not yet willing to adopt this model because of their institutionalized channel o f aid flow which do onto conform with the developing countries political structures. In essence, increased direct budget support by donors and good government structure of the recipient countries will increase aid effectiveness (Guillaumont & Chauvet, 2001)Need For Change in Aid Policy Critics have always advocated for foreign aid policy reforms. While United States foreign programme has noted high levels of success, it cannot be without a list of problems. The original aim of American aid policy was to generate and improve its economic sub-sectors such as the shipping industry, dump surpluses and promote trade. A clear example is the food aid policy in which food aid is no longer about providing a meal for the hungry but takes care of a multitude of objectives.A half of every dollar spent on food aid goes into the related costs such as processing and shipping. This reveals that policy changes must be put in place to make food aid perform to its fullest. This is because the current food aid policy strives to accomplish very many objectives, most of which are obsolete. It takes a very long time to transport food from a farmer to its final destination and at times this period takes up to five months. Such delay in delivery leads to added costs such as insurance and crew wages.Furthermore delay is the delivery in food aid cost lives in disaster situations. Money should be used to purchase food closer to their destination and reduce costs of transportation. A drastic shift must be made towards of food aid procuring, with purchase in the beneficiary nation and in the United States. Purchasing goods in countries closer to the beneficiary nations would strengthen agricultural market in these nations (Hansen & Tarp, 2000). The main objective here is local procurement of goods, not aid with conditions.America must move away from tied aid to make its foreign aid policy effective. The global economic crisis has led to questions about the general effectiveness of foreign aid. Questions as to how aid can be sustained continuously in times of economic recessions must be answered to achieve high performance. At the moment, American legislation demands that 50% of aid commodities must be processed and packed at home before shipment. Furthermore, 75% of food aid is managed by the USAID and 50% is under the management of US department of agriculture (Guillaumont & Chauvet, 2001).These commodities must be shipped in vessels flying US flags. Such conditions must be constantly reviewed to do away with long procedures of aid handling and delivery. While there are efforts to reform the aid policy, it is expected to take time before full effectiveness is achieved. The 1961 Foreign Assistance Act and the Farm Bill under President George Bush are some efforts to restructure United States foreign aid policy. An examination into different types of foreign aid reveals a complex scenario on how effective its overall objectives are.The reconstruction of countries reel ing from effects of war such as Iraq and Afghanistan are always controversial in nature. Given the overlap in time due to security related issues, it is almost impossible to accurately determine how much and to what level of effectiveness these aid constitute (Dalgaard & Hansen, 2007). Another area that requires total change is the technical cooperation. This is poorly defined due to its ambiguity and thus hard to measure. They are always under criticism due to the huge amounts involved but often not properly accounted for.Technical cooperation always means transfer of skills and knowledge from the donor country to the beneficiary country but always become controversial when they involve military aid assistance such as generous packages to Israel and Egypt. The so-called aid for national interest always attracts huge aid packages than moral areas such as poverty and disease alleviation. Pakistan is a major recipient of United States aid due to its influence and geographical location with Afghanistan and receives this foreign aid to maintain stability and peace in the region. America must do away with some aid conditionality.The imbalance in aid contracts creates conditions which translate into donor demands for change in social, political and economic affairs (Burns, 1984). One of the most absurd conditions from the western donors is the system of state control over all sectors of the economy. The demand for democratic states and good governance, free and fair elections, constitute to some of these conditions. Considering achievement of these conditions a yardstick to receiving foreign aid undermines its role and objects and thus makes it a political tool to control affairs of other countries.Reforms must be made on how aid is channeled to the beneficiary countries. Multilateral aid is always channeled through World Bank and other regional development banks while bilateral aid is paid direct to the beneficiary countries (Miyashita, 2003). Multilateral aid has so far recorded greater success than bilateral aid since it is not selective and undertakes its programmes on neutral basis. These aids are in the form of grants that ensure maximum utilization for the set objectives. Reforming policies in these sectors to ensure maximum transparency and reduce levels of political interference would definitely improve its performance.Conclusion Bilateral aid must not be used to hood-wink political leaders. It is obvious that some developing countries whose economic performances are poor depend mainly on foreign aid to support their programmes. Application of selective strategies and tough conditions driven by greed to control the smaller nations will eventually render the foreign aid ineffective. The way to go in improving the performance is forging a close alliance with the beneficiaries and improving levels of transparency (Toye, Harrigan & Mosley, 1995).The handling of foreign food must take into consideration the overall improvement of agricultu re and provision of close markets for agricultural markets to regions close to the beneficiary country. Foreign aid must therefore seek to improve the level of human development. References: Burns, W. J. , (1984), Economic Aid and American Policy towards Egypt. Sunny Press Dalgaard, C.
