The analytical linearity, detection limit, precision and accuracy, as well as diagnostic sensitivity, specificity and predictive values of red cell sorbitol (RCS) assay were evaluated using the fluorimetric enzymatic technique with the available laboratory facilities in a Nigerian Teaching Hospital. The assay was linear up to 40.0 nmol/ml. The detection limit was 0.55 nmol/ml. The within-assay coefficients of variation (CV) from low to high concentrations were in the range of 2.82% to 5.48%...

Responses to descriptions of racial bias toward African Americans by 84 Euro-Americans did not differ among Euro-American upper level students enrolled in Colleges of Education and Journalism.

The milk samples were collected from mothers who had lived in the area for at least 5 years, healthy and breast feeding their first, second or third child. Of the 175 mothers' milk samples analysed, the organochlorine pesticide residues were detected in the following order of frequency: pp-DDE, 100%; pp-DDT, 98%; and sum PCB, 53%. Of all the seven areas analysed the Kariba area had the highest mean level of sum DDT—25 259 ng/g milk fat and the lowest mean level of sum DDT of 1607 ng/g milk...

The present study was designed to examine whether a relationship exists between scores on simultaneous and sequential cognitive processes, on one hand, and performance on the Reading Decoding and Arithmetic subtests of the Kaufman Assessment Battery for Children (K–ABC), on the other hand, using a sample of 170 Egyptian school children in Grades 1, 3, and 5. To examine the differential magnitudes of the relationship between scores for cognitive processing and school achievement a two by two...

A number of thrusts were encompassed in the project scope, which was to examine the fatigue strength of extruded 6261-T6 I-beams with centrally located, welded cover plates under constant amplitude (CA) and variable (two-level repeated block) amplitude (VA) loading. The CA part of the work examined the effect of cover plate geometry, specimen size, thermal and vibratory...

It draws on two research...

New apatite fission track (AFT) data from the southern Red Sea volcanic and the Gulf of Aden nonvolcanic margins provide important constraints on the timing of crustal cooling relative to periods of volcanism and lithosphere extension. The AFT data define several regions of extension immediately adjacent to the Red Sea margin with AFT ages < 25 Ma and track-length distributions consistent with rapid cooling. Elevated Precambrian basement highs on the rift shoulder have AFT ages ⪢ 100 Ma and...

Abstract The social acceptance of a group of Zambian primary school children with intellectual disabilities by two groups of nondisabled children was examined. One group were in direct contact with the children with disabilities over a period of six months while the other was not. Nondisabled boys who had been in contact with children with disabilities had more positive attitudes than boys who had no direct contact, while no exposure effects were observed amongst girls. Gender differences...

ABSTRACT The article reports on relative gender access to secondary (grammar) school education from 1977 to 1990 in Imo State, Nigeria. To this end, time series data on secondary (grammar) school enrolment in Imo State from 1977/78 to 1989/90 were analysed. The findings are: (i) the existence of a gender imbalance in access to grammar school education in which the participation rate for girls was less than 40% up to 1980/81. This is discussed with reference to the prevalence of a...

Out of 2494 subjects screened in a Nigerian community, 28 patients with dementia were identified. Alzheimer's disease was diagnosed in 18 patients (64.3%), 16 of whom had probable Alzheimer's disease. Eight patients (28.6%) had vascular dementia while one patient each had parkinsonism with dementia and depression with dementia. Patients with Alzheimer's disease were significantly older, predominantly females and illiterates. Cognitive deficit commonly took the form of memory and judgment...
