Geophysical Information

A priori geologic and geophysical information has been used to construct conceptual VLF experiments on conductively and inductively coupled overburden geological models of the lead-zinc (Pb-Zn) mineralization zone found in southeastern Nigeria. This is based on the finite element approach to (1) simulate different geologic situations of overburden occurrence, (2) examine the roles played by overburden in modifying and masking VLF responses of a buried conductor target, and (3) confirm the effectiveness of VLF method in mapping lead-zinc lodes found in sedimentary terrains. The computed theoretical model curves and field examples are expected to serve as guide for VLF anomaly pattern recognition due to overburden thickness, resistivity and width of conductor in similar terrain as the study area.

A Prospective Study

Aims: To determine the prevalence of Trichomonas vaginalis and Candida albican infection among anasymptomatic pregnant population and to document their pregnancy outcomes.Methods: This was a prospective study involving antenatal clinic attendees at the Ebonyi State UniversityTeaching Hospital, Abakaliki, Nigeria. They were randomly recruited and informed consent obtained. Vaginalspecimens were collected from them and analyzed in the laboratory. They were followed up till delivery andpregnancy outcomes documented.Results: Two hundred expectant mothers were recruited. The prevalence rate of Trichomonas vaginalis andCandida albicans were 0.5% and 27.5% respectively. Due to the high dropout rate in the study, it wasimpossible to make any reasonable inference about the pregnancy outcomes associated with these conditions.Conclusion: There is probably the need for the use of more sophisticated methods for the detection ofTrichomonas vaginalis. The existing methods in most laboratories in the country may not be adequate. Thereis also probably the need for a larger sample size and a stricter follow up of the patients in order to documentany adverse pregnancy outcomes associated with these conditions.Keywords: Prevalence; Trichomonas vaginalis; Candida albicans; antenatal careDOI: 10.3126/njog.v4i1.3325Nepal Journal of Obstetrics and Gynaecology June-July 2009; 4(1): 11-14

Eight vegetable crops were sampled at five localities in Southeastern Nigeria and were found to harbour one or more species of thrips. The crops were Amaranthus hybridus, A. spinosus, Basella rubra, Solanum incanum, S. melongena, Hibiscus esculentus, Telfairia occidentalis and a species of Solanum. The sampled localities, with the frequency of occurrence of thrips, were Umuahia (29.6%), Owerri (28.5%), Port Harcourt (25.7%), Calabar (18.7%) and Enugu (6.0%). The studies revealed that crops with very heavy infloresences, e.g. Amaranthus hybridus, had a higher number of thrips (40%) per flower/leaf, while simple flowered crops like Telfairia occidentalis could only harbour a far lower number of thrips per flower/leaf. This showed a preference of these thrips for plants with heavy inflorescences which provided them with more protection, especially their larvae. Taxonomic/microscopic studies identified three species of thrips: Haplothrips gowdeyi that attacked 63% of all the sampled crops, Frankliniella schultzei was hosted by 50% of the crops, and Megalurothrips ventralis also preyed on 50% of the plant samples.
