The sperm mucus penetration test checks whether a man's sperm can move through the cervical mucus. This test is not done very often because there are other fertility tests that give more information about the fertility problem.
The current system of shifting cultivation can best be described as neo-traditional, composed of modern (colonial) and traditional (pre-colonial) structural elements. It is a locally adapted version of what was introduced by the Belgian Colonial Administration into the Ituri Forest under the heading of paysannat indigÃ¨ne including resettlement schemes and compulsory cultivation [Jurion and Henry 1967].
Horticulture is small scale, low intensity farming. This subsistence pattern involves at least part time planting and tending of domesticated food plants. Pigs, chickens, or other relatively small domesticated animals are often raised for food and prestige.or instance, in North America, it takes about 2 pounds of oil to produce one pound of wheat. In contrast, horticulture is labor intensive but not capital intensive. Horticulture is only economically practical as long as the population density remains low and land for new fields is readily available.
