Lab essays The purpose of this experiment was to understand how water is purified and the process that it goes thru. To find out how water is purified you will need 100 ml of foul water and you also need a funnel to set on the clay triangle support that goes the ring of the stand. You will also need a rubber tube that will connect to the funnel, and you must pinch it with your fingers to keep the water from flowing thru. Before you pour the water in the funnel you must stir it. Exactly at the moment you stop stirring it you will pour half of the water into the funnel, and tap the funnel so that the layers may separate. Once the layers have separated unpinch the lightly and let about half of the water flow into a clean beaker and label it beaker 1. Then you grab another clean beaker and drain the rest of the water into it and label it beaker 2. Pinch the tube and repeat the same steps again with the rest of the foul water and make observations and record it into your data table. Now you need to get a plastic cup and make holes on the bottom and put layers of gravel and sand in the cup. Set this cup on top of a clean beaker and pour the water from beaker 1 into the plastic cup and let the water filter. You can now get rid of the sand and gravel but whatever you do dont dump it down your sink and make observations and record the data from the purified water. You will now need some filter paper and fold it as instructed to fit in the funnel and this will act as a filter. Place the triangle thing on the on the ring of the holder and put the filter in the funnel. Put a clean beaker under the funnel and the funnel must be about 2-3 cm over the beaker. Put a teaspoon of charcoal in the purified water and pour the water into a 125 ml or a 250 ml Flask. Swirl the mixture for several seconds and pour it into the filter. Pour your water into a cylinder and make your observations and record your data. ...

Brandt Wallace essays Is language, or the actual act of speaking, solely created by the organs of speech? It is possible that some scholars might agree that communication is not totally vocal, yet how many of these same scholars would agree that language is not restricted to the vocalized speech that is so common in everyday life? This paper will argue that music, specifically instrumental jazz, can be characterized as an alternative language method. In order to gather information to write this paper, research was conducted at a downtown bar by observing a four piece jazz band and its audience. On first observing with the notion of "jazz as language" in mind, one very important question arose-what types of things does language convey? Frankly, the answer to this question could continue into book length, but there are several key correlations that the research revealed between the functions of jazz and verbal speaking as language types. The most obvious similarity is that jazz, like verbal speaking, is used to explain ideas and stories in great detail and emotion. Jazz expresses these ideas and stories to the audience through two distinct entities, group conversation and personal interpretation. On explaining these entities, one must understand the order in which they are given to the audience. The majority of the pieces that were performed used a common theme or melody, some songs having multiple melodies. In each song, this melody was expressed in one of two ways. In some songs, the band would start with the melody and then enter a "solo period," where each musician would solo. Before concluding the piece, the band would tie the piece together by playing the melody again. In other songs, the band would switch between melody and solo until each musician had soloed. The melody will be referred to as the "conversation." The solo is like an individual's personal thoughts on the conversation. In the jazz melody, or con...

Influence of Colonialism on Politics and Economics of Africa Nations Essay

Influence of Colonialism on Politics and Economics of Africa Nations - Essay Example A lot of literature exists on the influence of colonization on countries. However, most political science and history research analyzes the implication of colonialism in a holistic manner. Ziltener and Kunzler observe that this analysis is not sufficient as different colonial methods were used in different colonies (305). Moreover, the debate of the political and economic influence of colonialism in Africa is still open with some school of thoughts arguing that colonialism has assisted Africa more than exploited it. The assistance in form of infrastructure, education, urbanization, new political and economic systems is often cited. This paper will attempt to weigh in on the debate by using secondary data to explore the influence of colonialism in Africa by observing three African countries with distinct colonial history. This study will look at the historical and current political and economic structures of three African countries (Algeria, Liberia and South Africa). Since Liberia was not colonized by Europeans, Algeria attained independence in the late 60s and South Africa attained independence in the 1990s, the study assumes that the trends in their political and economic structures are directly linked to the nature of colonization. In order to
