Abstract Wonchi volcano (Ethiopia) is the second locality for wilkinsonite, the new mineral related to aenigmatite via the coupled substitution 2Fe 3+ = TiFe 2+ . Wilkinsonite occurs as relics surrounded by rims of riebeckite and biotite in a syenitic ejectum which also contains microphenocrysts of aenigmatite. The two minerals do not represent an equilibrium pair. They both formed in the magma chamber under plutonic to hypabyssal conditions, but during two following stages of...

As part of an overall research program concerning the broader aspects of policy development, in relation to liquid waste disposal in a developing nation, the need was identified to characterize the liquid wastes themselves. Only then can options be considered for disposal in relation to policy implementation and outcomes. This paper presents the results from the investigation of one of these liquid waste streams, that of sullage disposal in an Egyptian village. Results are presented for the...

The migrants are examined in contrast to women who remained residents in the rural home community. The major focus is on male‐female relations in the household. Findings indicate an erosion of the private status or domestic power of educated urban women, living in monogamous, nuclear family households.

Nigeria, like other countries faced with balance of payment difficulties and fall in commodity prices, started implementing a World Bank-sponsored structural adjustment program (SAP) as a strategy for economic recovery and growth. Available evidence has shown that the SAP has lowered real income value and increased malnutrition due to inaccessibility of the poor to nutritious food, with resultant nutritional consequences. Nutrition Education has been acknowledged as the most important method...

The pathological basis of hearing loss in bacterial meningitis was investigated using an animal model of Streptococcus suis meningitis. Forty guinea‐pigs were infected after their hearing had been assessed by brain stem auditory evoked potentials. In 17 animals, it was possible to repeat the procedure at the onset of meningitis; this included one animal with subclinical disease. Fifteen animals showed evidence of hearing loss, which on subsequent histological examination was found to be...

Some 288 Nigerian high school male adolescents in two different age brackets were administered the perceived somatotype scale and the Tennessee self-concept scale to determine the trend of self-concept ratings among subjects differentiated according to perceived somatotype-self, ideal and self-ideal discrepancy. Series of one-way ANOVA revealed significant differences in global self-concept among the perceived somatotype-self (PSS), the perceived somatotype-ideal (PSI) and perceived...

There is relatively little information about the dental health of Libyan children, so this study was initiated to assess the level of oral hygiene and the gingival and periodontal status in children living in urban and rural parts of Libya. Two thousands and fifteen children aged 7-16 years were examined during 1987 using World Health Organization criteria. The oral hygiene was found to be good (mean oral hygiene index = 0.12); boys demonstrated significantly worse oral hygiene than girls (P...

The module was developed around a nationally endorsed weaning food, “Weanimix”. PEMCOM interactive lectures were conducted with students at Specialist Teacher Training College, Winneba to test the module. The students had no prior training in...

To understand what people do and why, we need to know something about what they have done. Rarely, however, are social scientists direct observers of all events of interest to them. Hence, most often we rely on information that someone else has collected, more or less systematically, usually for some other purpose. The behavioural revolution in the social sciences, with its shrill cries of ‘falsifiability!’ and ‘reproducibility!’, has pushed us towards the sort of evidence that can be...

There is little doubt that American women are concerned with their appearance. Americans spend billions trying to improve their health, bodies, and appearance. In general we are healthier and more fit than ever, but less satisfied with the way we look (Cash, Winstead, & Janda, 1986). Despite their efforts to attain what is often an unattainable image, many women are dissatisfied with their own appearance. Psychological researchers have rigorously addressed the issue of physical appearance...
