It is also called the Partition of Africa and the Conquest of Africa. In 1870, only 10 percent of Africa was under European control; by 1914 it had increased to 90 percent of the continent, with only Abyssinia (Ethiopia) and Liberia still being independent.he only colony the United States had claim to was Liberia which was established by the American Colonization Society on January 7, 1822. The Berlin Conference of 1884, which regulated European colonization and trade in Africa, is usually referred to as the starting point of the Conquest of Africa.

Duration is a time measure of a bond's interest-rate sensitivity, based on the weighted average of the time periods over which a bond's cash flows accrue to the bondholder. Time periods are weighted by multiplying by the present value of its cash flow divided by the bond's price. A bond's duration will almost always be shorter than its maturity, with the exception of zero-coupon bonds, for which maturity and duration are equal.
We find that carbon-hydrogen and carbon-carbon bond lengths are now closer to the correct values. Under the old eFF, carbon-carbon double bonds were nearly the same length as single bonds but under the new eFF are the correct 1.33 length.arbon-carbon bonds are found to be more rigid as well. Previously, had a central carbon-carbon bond distance of 1.708; with the new eFF, it is now a more correct 1.519 (versus an exact value of 1.592).
