The Enugu State University of Science and Technology was founded in 1979 by Chief Jim Nwobodo as the Anambra State University of Science and Technology Enugu. It was the first ever state owned university in Nigeria. It was conceived with three campuses at Awka, Abakaliki, and Enugu. It had the first state funded Teaching hospital in Nnewi.Following the creation of Enugu State in 1991, the University took its present name. A large project by the Government of Enugu state to relocate the University has been underway in recent years. Early in 2006, the permanent site of the University in Ebeano City, with ultramodern facilities, became home to the first group of students and faculty to relocate from its temporary site.However, the hostels are still under construction following the recent transition of government It contains few number of faculties i.e.Faculty of MedicineFaculty of Social scienceFaculty of EducationFaculty of Natural scienceFaculty of Engineering among others;Current Pro-Chancellor - David OgbodoCurrent Vice-Chancellor - Professor Cyprian OnyejiRegistrar - Barrister Chris IgbokweBursar - Aloysius Chukwuemeka OkaforUniversity Librarian - George Igwebuike Wikipedia.

There are limited reliable information on the commercial production and utilization of proteases for detergent and other industrial uses in Nigeria. Hence, the purification and characterization of Bacillus sp. Gs-3 protease for its potential industrial uses were investigated. The dialyzed crude enzyme was purified 17-fold in a two-step procedure involving carboxymethyl sepharose ionic-exchange chromatography and phenyl sepharose 6-fast flow hydrophobic interaction chromatography. The purified enzyme had its optimal activity at pH 9.0 and 90°C and was stable over a pH range 8.0-11.0. It readily hydrolyzed all the tested protein substrates but exhibited highest affinity for gelatin (Km 0.15 mg mL -1). It retained at least 66.2±0.02% of its original activity in the presence of the tested local commercial detergents and removed bloodstains completely. Its activity was significantly (p>0.05) enhanced by Cu 2+ ion but strongly inhibited (75.6±0.07%) by Phenyl-methyl Sulfonyl Fluoride (PMSF). Thus, the enzyme demonstrated desirable properties suitable for its biotechnological applications especially in detergent industry. © 2011 Asian Network for Scientific Information.

Expert Systems with Applications | Year: 2010
Medical laboratory diagnostic report system in developing countries like Nigeria is awash with data that the medical expert is expected to correctly classify or interpret visually in consultation with medical literature. The advent of more system components (diseases, tests, et cetera) and growing pressure caused mostly by shortage of medical experts render a process that is time consuming, costly and unreliable. With proper knowledge elicitation, an expert system can automate the interpretation of medical diagnostic data based on knowledge elicited from human expert classifiers. There are numerous methods for eliciting expert knowledge, all aimed at ensuring that the data collected is valid and reliable. This paper proposes a framework for implementing an elicitation process aimed at extracting valuable knowledge (in production rules) required to build a medical laboratory diagnostic expert system expected to interpret medical laboratory test reports on areas of limited domains in medicine. We have implemented a prototype expert system that operationalizes this framework for tests on urine and blood samples. Preliminary results indicate that the framework is able to facilitate effective elicitation of parameters needed for a medical laboratory diagnostic experts system. © 2009 Elsevier Ltd.

The production of most bacterial proteases has always been with expensive refined substrates which tend to increase the production cost. Hence, a low-cost substrates and culture conditions capable of optimizing protease production by an isolated Bacillus sp. were studied. Bacillus sp. SW-2 which demonstrated the highest protease activity was selected and used for protease production by shake-flask fermentation technique at 180 rpm. The maximum protease yield for 72 h (2.697±0.19 IU mL-1) was achieved under optimized culture conditions of pH 9.0, temperature of 45°C and 5% inoculums density with soy meal (1%) and sugar cane bagasse (1%) as nitrogen and carbon sources of the fermentation medium. The protease yield obtained from using the cheap substrates at 72 h incubation was significantly (p>0.05) higher than that obtained from expensive substrates. The protease achieved >85.7±0.08% hydrolytic activities on the tested nitrogen wastes with soybean waste being the mostly hydrolyzed (96.3±0.13%). This result indicated the use of soy meal and sugar cane bagasse as rich substrates for maximum protease yield and the enzyme hydrolytic activity on nitrogen wastes suggests its application in environmental waste degradation. © 2012 Academic Journals Inc.

Carbon Balance and Management | Year: 2010
Background: Changes in agricultural practices-notably changes in crop varieties, application of fertilizer and manure, rotation and tillage practices-influence how much and at what rate carbon is stored in, or released from, soils. Quantification of the impacts of land use on carbon stocks in sub-Saharan Africa is challenging because of the spatial heterogeneity of soil, climate, management conditions, and due to the lack of data on soil carbon pools of most common agroecosystems. This paper provides data on soil carbon stocks that were collected at 10 sites in southeastern Nigeria to characterize the impact of soil management practices.Results: The highest carbon stocks, 7906-9510 gC m-2, were found at the sites representing natural forest, artificial forest and artificial grassland ecosystems. Continuously cropped and conventionally tilled soils had about 70% lower carbon stock (1978-2822 gC m-2). Thus, the soil carbon stock in a 45-year old Gmelina forest was 8987 gC m-2, whereas the parts of this forest, that were cleared and continuously cultivated for 15 years, had 75% lower carbon stock (1978 gC m-2). The carbon stock of continuously cropped and conventionally tilled soils was also 25% lower than the carbon stock of the soil cultivated by use of conservation tillage.Conclusion: Introducing conservation tillage practices may reduce the loss of soil carbon stocks associated with land conversion. However, the positive effect of conservation tillage is not comparable to the negative effect of land conversion, and may not result in significant accumulation of carbon in southeastern Nigeria soils. © 2010 Anikwe; licensee BioMed Central Ltd.

Sixty six vertical electrical soundings (VES) have been used to evaluate the ground water potential in Nsukka Local Government Area of Enugu State, Nigeria. The project domain lies within longitudes 7°13′00″ - 7°35′30″ and latitudes 6°43′30″ - 7°00′30″ and covers an area of about 480 km2 over three main geological formations. The resistivity and thickness of the aquiferous layer at various observation points were determined by the electrical survey. Also zones of high yield potentials were inferred from the resistivity information. Transmissivity values were inferred using the calculated Dar Zarrouk parameters. Results show highly variable thickness of the aquiferous layer in the study area. Aggregate transverse resistance indicates greater depth of the substratum in the southeastern part of the study area, underlain mostly by the Ajali Formation. High values of transmissivity also predominate, thus suggesting thick and prolific aquiferous zone. © 2010 Academic Journals.

Geochemical and microbial studies were carried out on surface and groundwater from the Abakaliki shales, Enugu, Nigeria. The study involved a total of twenty-five samples, which were analyzed to determine major ion concentrations and coliform status. Results of the analyses show that the pH of the waters range from 6.8 to 8.4 with most values clustering around 7.0 (neutral). Values of total dissolved solids concentration range from 827.8 to 1334 mg/l which suggest brackish water. High values of dissolved oxygen indicated strong oxidizing conditions in the regolith aquifer. The interpretation of ionic concentrations suggests that the chemistry of the ground water in the aquifer is established initially by the composition of ancient connate water trapped in the sediments. As the aquifer becomes increasingly recharged by rainwater there is a corresponding dilution plus the incipience of important reactions like natural softening and pyrite oxidation. The origin of the connate water is most probably marine. Microbial studies revealed that all the waters are heavily polluted with respect to coliform bacteria. The presence of specific pathogens like Salmonella spp, E. Coli and Pseudomonas spp in some of the samples suggest that the water supply of Abakaliki City should never be used without thorough treatment.

Patient Preference and Adherence | Year: 2011
Background: The purpose of this study was to investigate the influence of locus of control on adherence to a treatment regimen among hypertensive patients. Methods: The participants were 100 previously diagnosed hypertensive patients drawn from the Ituku-Ozalla University of Nigeria teaching hospital, using a purposive sampling technique. All participants were individually administered the Wallston, Wallston & Devellis (1978), Multidimensional Health Locus of Control (MHLC) scale, and Drug Adherence Questionaire (DAQ) by the researchers. A one-way factorial design and analysis of variance with unequal sample sizes were used to analyze the data. Results: Internally-oriented patients adhered more to their treatment regimen than externallyoriented patients, F(1.98) = 18.2 (P< 0.01). Conclusion: Locus of control should be taken into consideration in the review of treatment packages for patients. This is because the efficacy of drugs depends to a reasonable extent on adherence to the schedule. If drugs are not taken as prescribed, their potency may be affected or wrongly assessed. © 2011 Omeje and Nebo, publisher and licensee Dove Medical Press Ltd.

Three hundred and twenty two vertical electrical soundings (VES) have been used to evaluate the hydraulic properties of aquifers in Enugu State, Southeastern Nigeria. The project domain lies within longitudes 7° 6' E to 7° 54'E and latitudes 5° 56'N to 6 °52'N, and covers an area of about 7161 km2 over eight main geological formations. The thickness, lateral extent and resistivity of the aquiferous layers were determined by the electrical survey. Also, zones of high yield potentials were inferred from the resistivity information. Transmissivity values were inferred using the empirical relationship between hydraulic conductivity and formation factor. Results show highly variable thickness of the main aquifer in the study area. Aggregate longitudinal conductance indicates greater depth of the substratum in the central part of the area, underlain by the Ajali and Nsukka Formations. High values of transmissivity, specific yield and moderate porosity also predominate, thus suggesting thick and prolific aquiferous zone. Lower average values of these parameters were obtained in southwestern and eastern parts underlain by the Imo and Ezeaku/ AwguNdeaboh/ Nkporo Formations, with the eastern part recording the lowest values, except porosity with the highest estimated average value. Maps of various geoelectrical and hydraulic parameters have been produced and the overall results can serve as a useful guide in planning a drilling program in the study area. © 2011 Academic Journals.

Antifungal evaluation of the rhizome, stem and leaf extracts of Anchomanes difformis (Blume) Engl on post-harvest rot fungi of root and tuber crops in Nigeria at different concentrations were investigated. The rot fungi screened were Botryodiplodia theobromae Pat; Sclerotium rolfsii Sacc; Fusarium solani (Mart) Sacc; Rhizopus stolonifer (Ehren ex.Fr.) Lind, Aspergillus niger van Tiegh and Pénicillium oxalicum Currie and Thiam. Results showed that all the extracts at different concentrations of 100 mg/mL, 80 mg/mL, 60 mg/mL, 40 mg/ mL and 20 mg/mL inhibited mycelial growth of the test fungi. Growth inhibition of these root and tuber rot fungi increased with increasing concentrations of each extract. The extracts of rhizome showed more inhibitory potency followed by the leaf extracts on all the six test fungi than the stem extracts. The significance of these results on the storage of root and tubers crops was discussed. © Global Science Publications.

Unaffordable medical bills is a major barrier to utilization of maternal and child healthcare services. This is associated with very high maternal and perinatal mortality and the inability to attain the MDG4 and MDG5 in many developing countries. This study examined the uptakes of obstetric services following introduction of Free Maternal and Child Health Care (FMCHC) in Enugu State University Teaching Hospital, Southeast Nigeria and its impact on the maternal and neonatal healthcare outcome. A retrospective comparative study of the utilizations of maternal and child healthcare services from June to August in 2008 with that of September to November in 2008 after commencement of the FMCHC. Information on all the pregnant women and neonates in their first week of Life that attended clinic within the period under review was collected from the Medical Records department of the hospital. FMCHC caused tremendous increases in the uptakes of antenatal booking (202.2%), and hospital delivery (151.8%). It also resulted in decreased maternal and perinatal mortality by 16.4% and 34% respectively. Implementation of FMCHC can make MDG4 and MDG5 attainable in sub-Saharan Africa.
