microcephaly

Microcephaly

Microcephaly is a medical condition in which the brain does not develop properly resulting in a smaller than normal head. Microcephaly may be present at birth or it may develop in the first few years of life. Often people with this disorder have an intellectual disability, poor motor function, poor speech, abnormal facial features, seizures, and dwarfism. The disorder may stem from a wide variety of conditions that cause abnormal growth of the brain, or from syndromes associated with chromosomal

tetraethyllead

Tetraethyllead

Tetraethyllead, abbreviated TEL, is an organolead compound with the formula (CH3CH2)4Pb. TEL is a petro-fuel additive, first being mixed with gasoline beginning in the 1920s as a patented octane rating booster that allowed engine compression to be raised substantially. This in turn caused increased vehicle performance and fuel economy. TEL had been identified chemically in the mid-19th century, but its antiknock effectiveness was discovered in 1921 by the General Motors research laboratory, whic

drylands

Drylands

Drylands are defined by a scarcity of water. Drylands are zones where precipitation is balanced by evaporation from surfaces and by transpiration by plants. The United Nations Environment Program defines drylands as tropical and temperate areas with an aridity index of less than 0.65. One can classify drylands into four sub-types: dry sub-humid lands semi-arid lands arid lands hyper-arid lands Some authorities regard hyper-arid lands as deserts although a number of the world's deserts include bo
