OAS last meeting :: essays research papers

Organization of American States   Ã‚  Ã‚  Ã‚  Ã‚  The Organization of American States (OAS) brings together the countries of Western Hemisphere to strengthen cooperation and to advance common interests. It is the region’s premier forum for multilateral dialogue and concerted action. The OAS helps in many different ways to make changes around the world. Actually the OAS is having a meeting in Ft. Lauderdale (Florida) and some of their actions are showing their interest to defend democracy and human rights around Latin America as for example in Venezuela. Furthermore, the OAS demonstrates interest in Strengthening Security, and combating illegal drugs in Colombia (South America); one of the most important things the OAS is focused on is the fostering free trade between countries’ members association. This OAS meeting in Ft. Lauderdale is making history, focusing in the most critical problems that countries from Latin American are trying to combat.   Ã‚  Ã‚  Ã‚  Ã‚  The OAS plays a key role in strengthening democratic and human rights institutions and practices in the countries of the Americas. As for example in Venezuela during the meeting, the OAS shows their interest in the political tension that Venezuela is passing through after the last president elections. In Venezuela the opposition reclaims that past election was not totally legal, these accusations to Venezuelan’s government made the OAS to worry about the status of democracy and human right protection to Venezuelan society. According to news article on the Miami Herald another fact which makes the OAS worry about Venezuela’s situation is the actual President Chavez’s hostility against the United States type of democracy. The OAS discuses all these conflicts during the recent meeting and finally Venezuela accepts the role in the OAS for non-governmental groups that evaluates countries where democracy is allegedly at risk, such as Venezuela.   Ã‚  Ã‚  Ã‚  Ã‚  The OAS is working on different limit borders to make Latin American countries safer, and they are also looking forward to prevent terrorism by strengthening control borders, by trying to eliminate drug trafficking and also by increasing security among law enforcement authorities in different countries. For example in Colombia (South America); during the meeting the OAS members discuss Colombian treaties to acquire national peace; this process supports, informs, helps and verifies initiatives from Colombian people to defend their social security in small regions of their territory.   Ã‚  Ã‚  Ã‚  Ã‚  Since OAS’s creation, their main goal has been to create a hemisphere-wide trading zone, called Free Trade Area of the Americas (FTAA).

Results and Discussion Example

Results In this experiment we used paper chromatography to determine the amount of chlorophyll a, chlorophyll b, xanthophyll, and beta-carotene in a tube of blended leaf extract. We recorded our findings on the table labeled table 1. Table 1 shows the transmittance at each wavelength on a table from 400 to 720. The information on Figure 1 came from the leaf extract on the paper chromatography that we used; with the help of acetone we saw the spectrum and the differences of the different pigments.Percentage transmittance in Table 1 show that the lower the number, the more dense that solution is at that specific wavelength. As the numbers get higher, the less dense it is and if the number is 100 at a specific wavelength then the solution was clear. As we can see from Table 1, each of the pigments had different low transmittance based on how high the absorption was in each of the pigments. For this we calculated that at there was a peak on the graph at the lowest points in table 1.For i nstance, in the chlorophyll a column in Table 1 the lowest points on the graphs at 8 and 28 and also at 44, which shows that there will be a peak around those points. In chlorophyll b, the lowest points are from 25. 2, 12. 4, and 9. 4, which would be the first peak and the next will be at 55. 6. In Xanthophyll, the points were the first peak will be are 52. 4, 43. 6, 44. 8, and 53. 0. Lastly in Carotene, the graph will peak at 92. 2, 93. 6, and 92. 4. By using these points we predicted the behavior of the graph.TABLE 1| | | Wavelength| Chlorophyll a| Chlorophyll b| Xanthophyll| Carotene| 400| 12| 42| 61. 8| 96. 8| 420| 8| 25. 2| 52. 4| 99. 6| 440| 28| 12. 4| 43. 6| 92. 2| 460| 71. 5| 9. 4| 44. 8| 93. 6| 480| 81| 48. 4| 53| 92. 4| 500| 88| 88. 6| 83. 2| 99. 2| 520| 88| 91. 4| 94. 2| 100| 540| 84. 5| 87. 4| 95. 6| 100| 560| 83| 85. 2| 96. 4| 99. 2| 580| 71. 5| 83. 4| 96. 2| 100| 600| 72. 5| 76. 8| 96| 100| 620| 61. 5| 78. 2| 94. 4| 100| 640| 61. 5| 59. 6| 94. 6| 100| 660| 44| 55. 6| 9 3. 2| 100| 680| 48. 8| 67. 8| 92. 6| 99. 8| 700| 64. 6| 60| 91. 4| 92. 8| 720| 50. 6| 52. 4| 89| -|On the graph labeled Figure 1, it shows the absorbance of each of the pigments that are shown in Table 1. The difference between Table 1 and Figure 1 is that where table 1 shows the transmittance points of each wavelength of each pigment, Figure 1 shows the absorption peaks of each of the wavelengths. For chlorophyll a, the highest peaks are at 420, but then the graph plummets at around 450 and has another peak between 650 and 700. For chlorophyll b, the highest peaks of absorbance are between 450 and 500 then it makes a big plummet around 500 and has another peak between 640 and 660.For Xanthophyll, the only peak is between 420 and 480, then the graph as minimal movement from there and stays in the 90 range never hitting 100. Lastly, beta-carotene has small peaks at 440 and 460 and then the graph stays almost stagnant at 100. Discussion The purpose of this experiment was to find out w hy the leaves on a tree changed color in the fall. We predicted that the molecules in the leaves of the tree attributed to the change. We found out that the molecules: Chlorophyll a, Chlorophyll b, Xanthophyll, and Beta-carotene are the main molecules that reside in a leaf.We also stated that the tree absorbs the elements found in some of these molecules so that they can be used in the spring, when the trees are green once more. This prediction came from when we studied the molecular composition of each of the molecules and correlated the results the experiment and the specific elements that the tree would have needed for another year. The results of this experiment show that at there is less chlorophyll a and chlorophyll b in the composition of the leaves that were used.This meant that when the season is changing, the molecules in these structures start to be absorbed back into the tree. This conclusion came from the fact that in table 1 from 420 and 440 Nano meters there was a low transmittance rate of these two molecules, which means that the absorbance rate was high. During the fall season there is not enough sunlight for the trees to perform photosynthesis to make their own food, what a plant needs to survive would be the Magnesium and Nitrogen that are found in the molecular structures of chlorophyll a and b.Therefore they absorb all of these nutrients that the tree needs to survive so that they can make it thorough the winter. Errors could have been made with this experiment. Some of them include that the individuals in different groups did not have the same control as the others. We did not measure the same amount of acetone in each vial nor did we measure how much of the leaf extraction each person used. Another source of error would be how the spectrometer was used, if it was reset the same at each wavelength each time.Compared to previous experiments the information that was collected in this one was accurate. The peaks for each pigment were roughly around the same wavelength. The standard for chlorophyll a was peaks at 430 and 662, chlorophyll b peaks at 453 and 642, xanthophyll a range from 450 to 550 and for the beta-carotene peaks at a range from 450 to 550. Our results were roughly around the same as you can see from Table 1. The end result of the experiment was successful, because of the results that we produced were similar to the results of previous experiments.

International Trade Essay - 814 Words

International Trade In today’s world there are many issues in need of reformation, one of which is international trade, otherwise known as globalization. Although there are a great deal of rules, regulations, and policies imposed on international trade, the manner in which those rules have been enforced is a major controversy that seems to be escalating day by day. At the center of the controversy is the World Trade Organization (WTO). The WTO was established in 1995 in order to transform the General Agreement on Tariffs and Trade (GATT) into an enforceable global commercial code. Critics of the WTO say that instead of being run democratically and in the interest of member countries, it has become the enforcer of corporate managed†¦show more content†¦Once again they are demonstrating that the pursuit of wealth is it’s number one goal and ignoring massive protests launched by American labor unions who argue that the pact could cost hundreds of thousands of American jobs due to an increase in Chinese imports and companies who may decide to relocate factories to China, where cheap labor can be utilized. Another prominent issue concerning the WTO is organically produced foods, which have become a highly demanded product in the last few years. Countries take part in distributing and manufacturing foods because it has led to an increased amount of trade (increasing exports and minimizing imports). The parties that have benefited most from organically produced foods are farmers and agricultural businesses in other countries. But a negative impact would be increased competition among businesses. This represents a rational point of view. Competitors are only concerned with their own wealth and distinction. The company and its well-being is their self interest. Their primary goal is success. Businesses expect other businesses, along with the customers, to show obedience. Companies, individuals and countries alike all view the perspective of the rational dimension. The economy as a whole is rational. Groups such as the World Trade Organization (WTO) are using their hierarchy of power to benefit themselves.
