Labarotary - Lab Report Example In addition, infants have still to develop a urinary system that concentrates or dilutes urine in response to changes in extracellular fluid. Aside from that, they are still unable to effectively communicate their complaints, It is thus important that an outside monitoring of water loss and input be conducted to prevent complications such as dehydration or edema (Ambalavanan, 2010). Early determination of abnormal fluid levels gives room in early intervention and prevention of complications. Usually, one can predict predilection of infants to abnormal fluid levels by the maternal and newborn history. As well, measuring of fluid output through urine, stool, nasogastric, orogastric, and cerebrospinal fluid may be conducted (Ambalavanan, 2010). For this experiment, four nappies per pair were prepared. After previously weighing all four, two (labelled 1 and 2) were added with 15-50 ml water, while the remaining were added with 15-50 l of concentrated salt. Weight differences between unused and wet nappies were then determined and presented in the tables below. Table 1 summarizes the data collected by the pair of experimenters. As can be seen, the differences among the unused nappy weights were minimal, with the mean weight at 10.2 Â ± 0.2 grams. Any detected differences among wet nappies, must thus be because of the fluids they contain, and not of the material they are made of. Looking at the data of other pairs (table 2), specifically of group 2, it can be seen that equal volumes of water and salt solution does not cause any significant differences in the change of nappy weight. In support of this data, group 3 found that pouring a volume of the salt solution that was twice as much as the volume of water caused almost twice as high weight difference as that recorded in nappies added with the same amount of water. Data gathered by this pair of experimenters, as well as of other groups were not used in

What are the main features of a bipolar world Illustrate your answer with examples - Essay Example The bipolarity as explained above was a period in which US, her allies, the USSR, and her allies held extreme views in all manner of sense; from political to economic issues. The period was also characterized with suspicion and propaganda, the suspicion that USSR or United States were in the process of developing weapons of mass destruction. It must be noted that there were no formal confirmation of this allegation rather a state of being insecure given that both USSR and the US emerged as the World super power and had Veto powers in the UN council (Hunt, 147). It can be believed that the war bipolarity was necessitated by the fact that both USSR and US emerged as super powers and were posing significant threat to each other, the only way they could deal with the situation was holding contrary view. It accentuates our belief that way because in any event, the two countries were in the same front all along from 1914-45. Even though in the bipolar world there were no direct military confrontations, most of the historian have alluded that it can be termed as the world war III. This is because the two opposing groups, USSR, and U.S were involved in indirect wars by supporting their proxies with military and economic aids. The situations were glaring in the cases of Korean and the Vietnam. The Cuban missile crisis was also a manifestation of the proxy involvement of the two antagonistic sides in 1962. Some of the factors that led to the bipolarity were; The Soviet were in a mad rush to spread communism ideology in the world as a matter of having no option to even the minority countries, this was against the American position that was hinged more on democracy. The American acquisition of the all-lethal atomic bomb made USSR restless considering that they were also super powers. In as much as the two countries emerged super powers in the concluded world wars, they had
