Empire Building in Africa - Research Paper Example Many of the European Nations developed an interest in Africa due to various reasons. First, in the wake of industrial revolution, these nations realized that they required extra raw materials to use in their newly established industries. In addition, these European nations required new markets for their manufactured goods, which stirred up competition for Africa. Due to this, many European nations or colonial powers confiscated large segments of Africa and established empires (Lakeview.org, 2008). In addition to need for markets and raw materials, the European nations also wanted to acquire power and reputation. In this regard, these nations competed for a larger control of Africa. The nations thought that they would be more powerful and would have more reputation if they control and rule over a large territory. The combination of these factors led for the scramble for Africa and eventually the establishment of colonial rule in the continent (Lloyd, 2009). Before the 19th century, the whole world regarded Africa as the Dark Continent. This is because a part from the inhabitants of Africa, the rest of the world did not know anything concerning this continent. The first contact between the Europeans and Africans was through trade, which gradually begun between the Europeans and African traders in the coast of Africa. Conversely, since this trade occurred at the coast, the Europeans were interested with the interior of Africa, and some started to explore this continent in the early 19th century. The first European explorers in Africa were the missionaries who had the sole purpose of spreading the gospel to Africans as well as to eliminate slave trade. These missionaries deemed that slave trade was poisonous and had negative consequences to most African poor (Nosotro, 2010). As the Europeans endeavored to explore Africa’s interior, they encountered a problem. They could not travel in to the interior in large numbers due to inconveniences

Casein micelle structure Models and muddles Assignment

Casein micelle structure Models and muddles - Assignment Example All models that are proposed and should be working should be constructed in a way that it can imitate the behaviors of the represented structure. From the article, we can say that both models being used for representations are muddles. Both models are seen to be reaching their ends. It is imperative to note that milk composition do vary greatly in and in the total concentration of proteins, as well as their relative proportion. From this idea, we can summarize that in every model formed to explain the casein and casein micelle properties, the model cannot be specific to the species from which the milk comes from. Nonetheless, the model should be looking forward to recognizing that all milk from all mammals share same characteristic in that they all contain casein micelles (Horne 2006, pp. 148-153). There are various models put across by scholars. All the scholars have been speculating and striving to come up with a clear model. Each model do possesses its own weaknesses and strengths. The researchers have to come up with the restrictions and any raised requirements prior to choosing the best applicable model. In addition, the micelle system is exposed to advanced physical and technological environment to dig out their properties. The properties and the composition of milk molecules vary. The phosphoproteins are the casein proteins, and they are divided majorly into two groups. These two groups are responsible for the casein properties in mixtures where it prevents calcium from precipitating the groups that are calcium-sensitive. Two more groups that are considered to analogs of the two major groups have also been identified. This makes the total molecules of caseins to be four in total. Through research, it noted that most of the mammalian milk contains the four molecules that include k- casein, alpha â€Å"s1†, alpha â€Å"s2† and beta
