Abia State University is one of the state owned universities in Nigeria.And best state university in nigeria These state academic institutions were created to expand admissions and bring professional skills, expertise and modern research facilities close to the city and rural dwellers; and have helped talented students to obtain Higher education.The inception of the university was in 1981 in the former Imo State under the name of Imo State University, Uturu, Okigwe. The university was established by Sam Mbakwe when he was Governor of old Imo State. Following the creation of Abia State in 1991, the Uturu campus of the University was ceded to Abia State; and is now known as Abia State University Uturu, Isuikwuato Local Government Area, Abia State, Nigeria. The university is organized in colleges and schools having been founded on the same collegiate system operated by University of Nebraska. Abia State University offers undergraduate, graduate and doctorate degree; and has two campuses with its main campus located in Uturu while its College of Agriculture and Veterinary Medicine is housed by the campus in Umuahia, Abia State capital.

Geohydraulic parameters are essential elements in groundwater resource management and conservation. Most of these parameters especially the hydraulic conductivity and transmissivity are usually estimated from pumping test carried out on drilled boreholes. This paper presents a study conducted in Abi area of the Ikom-Mamfe Embayment with the objective of estimating aquifer parameters from 30 evenly distributed vertical electrical soundings using the Schlumberger configuration and hydrogeologic measurements from 28 boreholes within the area as an alternative way of generating an initial data for groundwater characterisation and quality assessment in the area. The results showed low resistivity ≤45Ωm, hydraulic conductivity ≤2.0×10-5m/s (≤1.7m/day) and transmissivity ≤5.2×10-4m2/s (≤45m2/day) for the water-bearing aquifer horizons in the northeastern and northwestern parts of the study area due to the nature of the aquifer system that were predominantly fractured shale. The sand based aquifers had higher values in the neighbourhood of ~100-800Ωm, ~4.0×10-5-1.0×10-4m/s (~3.46-9.04m/day) and ~6.94×10-4-3.81×10-3m2/s (~60-330m2/day) for the respective parameters mentioned above. The potability of the groundwater system as observed from hydrogeologic measurements of water samples from most boreholes were relatively poor, having electrical conductivity and total dissolved solids values of ~250-931.0μS/cm and ~500-623.77mg/l respectively due to the influence of clay minerals within the aquifer horizon. Some of the vertical electrical sounding points were taken in the vicinity were pumping tests and lithologic data were available for adequate comparison of the results. © 2014 Elsevier Ltd. Source

Intracranial calcifications underlie certain brain diseases which may be de novo or systemic. But calcifications un-connected to pathologies are classified physiological. To evaluate physiological intracranial calcifications in Douala with establishment of earliest age range of detection. Prospective study of brain computed tomograms was done from April to October 2009 using Schumadzu CT Scan machine. Axial, reconstructed and bone window images as well Hounsfield unit measurements were used for final evaluations. RESULTS were analysed with SSPS 3. 132 patients with 75 males and 57 females were studied and 163 separate calcifications were identified due to co-existent calcifications. The highest calcification was in choroid plexi, constituting 56.82% of the studied population. This was followed by pineal gland. Both were commonly co-existent with advancing age. These calcifications were first seen at 10-19 years. No type of physiological intracranial calcification was seen below age 10. The least calcification of 0.76% of population was in dentate nucleus. No intra-cranial physiological calcifications started earlier than 9 years in Douala, a city in Cameroon, Central Africa. Source

The aim of this study was to determine the concentrations of Pb, Cd, Co, and Cr in cosmetic talcum powders regularly used in Nigeria. The samples were mineralized using acids and the trace metal concentrations measured using flame atomic absorption spectrophotometer. Mean concentrations of the trace metals analyzed were 5.0±1.0 mg kg -1 for Pb, 2.1±0.3 mg kg -1 for Cd, 0.7±0.1 mgkg -1 for Co, and 0.2±0.1 mg kg -1 for Cr. Higher metal concentrations compared to others were obtained in few samples manufactured by certain companies, indicating that raw materials used and exogenous contamination could be major contributory factors. The results of this study were generally within regulatory limits. The slightly elevated levels of Pb in few samples indicate that the use of certain talcum powder products could constitute trace metal exposure routes to users. Thus, there is a need for regulation of trace metal levels in cosmetic powders through the establishment of national guidelines. © 2011 Taylor & Francis. Source

Background: Low birth weight deliveries are major causes of a huge health burden on poor economies around the globe. It is even more worrisome in developing countries. Materials and Methods: The obstetric records of all low birth weight (LBW) deliveries were reviewed from 1st June 2005 to 30th May 2009. Results: The prevalence of LBW deliveries was 8.3%. Of the LBW babies, 68.4% were preterm, 53.6% were small for gestational age (SGA) and 12.6% were products of multiple gestations. Predominant factors associated with LBW delivery included nulliparity, low parities (1 and 2), parturient aged 25-35 years (80.6%), hypertensive disorders of pregnancy, and short birth spacing (84.4%). Conclusion: Most LBW babies were preterm delivered by low parity parturient aged 25-35 years with short inter-pregnancy intervals. Effective family planning and antenatal services provided particularly for these categories of potential parturient could help to curb the incidence. Source

The concentrations of lead and copper in sclerotium of the mushroom Pleurotus tuber-regium widely consumed in Southeastern Nigeria were determined. The specimens purchased from different markets were mineralized with H 2SO 4 and H 2O 2 and analyzed using flame atomic absorption spectrophotometer. The concentrations of Pb ranged from 0.2±0.1 mg kg -1 to 0.8±0.5 mg kg -1 with approximately 91% of the results being below 1mg kg -1. The concentrations of Cu ranged from 0.5±0.2 mg kg -1 to 1.2±0.6 mg kg -1 with 78% of the results below 1mg kg -1. The results were compared with the literature and levels set by regulatory authorities, with the conclusion that the consumption of sclerotium does not pose a toxicological risk. The low Pb content of the studied products would contribute to only about 1% of the provisional tolerable weekly intake of Pb. The Cu contents would contribute to nutritional intake of the metal in the general population. It is recommended that the outer layers of the sclerotia be properly scrapped before use to reduce metal contamination from exogenous sources. © 2011 Taylor & Francis. Source
