Evaluation of aquifer potential, geoelectric and hydraulic parameters in Ezza North, southeastern Nigeria, using geoelectric sounding

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

Estimation of hydraulic parameters in coastal aquifers is an important task in groundwater resource assessment and development. An attempt is made to estimate these parameters using geoelectrical data in combination with pore-water resistivity of existing wells. In the present study, 29 resistivity soundings were analysed along with 29 water samples, collected from the respective dug wells and boreholes, in order to compute hydraulic parameters like formation factor, porosity, hydraulic conductivity and transmissivity from coastal region of north Sindhudurg district, Maharashtra, India. The result shows some parts of the study area reveal relatively high value of hydraulic conductivity, porosity and transmissivity. Further, a negative correlation is seen between hydraulic conductivity and bulk resistivity. The hydraulic conductivity is found to vary between 0.014 and 293 m/day, and the transmissivity varied between 0.14 and 11,722 m2/day. The transmissivity values observed here are in good correspondence with those obtained from pumping test data of Central Ground Water Board. These zones also have high aquifer thickness and therefore characterize high potential within the water-bearing formation. A linear, positive relationship between transverse resistance and transmissivity is observed, suggesting increase in transverse resistance values indicate high transmissivity of aquifers. These relations will be extremely vital in characterization of aquifer system, especially from crystalline hard rock area.

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.
