The author describes an investigation into the use of West African folklore in the school curriculum by means of an African folktale which became the basis for a project in the class music lessons. Starting with research into West African folklore, particularly children's stories and songs, in Ghana and Nigeria between 1979 and 1983, music was composed in a basically African style to go with an adaptation of one of the stories. The practical work in a London primary school investigated ways...

In 1973, the Benin University introduced demography training in its geography and economic courses, but it is only since the creation, in 1975, of the Demographic Research Unit, in the bosom of the school of economic technics and management, that demography training has been extended to other fields: social sciences, urbanization medicine, and science. At a university level, it is through courses that basic demography training is given, with specific applications for each field. At the...

The parity and the perinatal mortality of 226 married Nigerian female diabetics, aged 20 to 76 years (mean 47.1 years), and 226 married female nondiabetics matched for age and educational level with the diabetics were studied. There was no statistically significant difference between the diabetics and nondiabetics in terms of primary infertility, irrespective of age of onset of diabetes. In the group with one to four deliveries, the nondiabetics significantly outnumbered the diabetics (P...

This paper deals with the geological structure and the petrologie evolution of Karisimbi, the highest volcano in the Virunga region. As this paper is intended to be understood by non-geologists, a brief review about the methods used by volcanologists, should make things clear for the reader. The field-work data enabled us to describe the morphology, structure and the evolution of Karisimbi. The results of the laboratory studies are summarized in the section petrography-petrochemistry, where...

The biosynthetic activation of many hormonal peptides requires enzymatic alpha-carboxyamidation via glycine-extended intermediate forms. By specific radioimmunochemical measurement on extracts of guinea pig antra, we found that vitamin C deficiency induced a 30-fold increase in glycine-extended (i.e. inactive) gastrins. The results indicate that ascorbic acid is necessary for alpha-carboxyamidation in vivo, and thus, that the biosynthetic activation of hormonal peptides can be modified by simple dietary means.
