Caleb University is a private university located in Imota Lagos Nigeria.The systematic history of CALEB UNIVERSITY dates back to 1986 when Prince Oladega Adebogun planted the initial seed for a nursery and primary school in the heart of Mainland Lagos. The seemingly intractable falling standard in public sector education and the demand amongst most parents for schools with high academic standards, as well as the inculcation of true Christian values served as the necessary impetus for the creation of Caleb Nursery and Primary School.The high academic attainment within the school, coupled with the exemplary moral behaviour of the students increased demand for places in the school. Parents also began to yearn for a secondary institution that emphasizes the same objectives, ambitions, values and teaching methods. This, logically, paved the way for the establishment of Caleb International College in Magodo GRA, Lagos, in 1995.The college served as a natural transition path for many pupils who have attended Caleb Primary School. Within a few years of establishment, the performances of the college students at the Junior and Senior Secondary School Certificate examinations quickly established Caleb amongst the ranks of high flying secondary schools in the Country. The college expanded its extra-curricular programme, expanded its music band, and included overseas study tours for its students from 1999.In 1999, application for places at the College reached unprecedented level, with full applications to every available place. Such positive interest agitated the need for a bigger location. Caleb International College continued the rich tradition of moral and academic excellence and sometime in 2003, a branch of the College was established in Lekki to cater for parents residing in the Ikoyi, Victoria Island and Lekki axis of Lagos.To maintain its position as a prime provider of qualitative education and respond to the industrial demands for staff of true international calibre, the establishment initiated the necessary process for the introduction of a Cambridge O level programme and International General Certificate of Education in 2004. Caleb's position as an international organization was truly recognized in 2004 when it was admitted as a full member of the International School's Association .Prince Adebogun also felt deeply inspired to establish a university that will do for tertiary education, what Caleb has creditably done for primary and secondary education and in response to the invitation of the Federal Government of Nigeria through Act no. 9 of 1993 to allow Private Corporate bodies or individual Nigerian Citizens to establish and run Universities, subject to meeting approved guidelines such as having an approved Academic Brief, Master plan, University Law and proven ability to finance such a project.By 2005 much progress had been recorded with the production of the Draft Academic brief, Draft University Law and purchase of over 100 Acres of land in Imota, Lagos State. By November of the year same, the first NUC- SCOPU verification visit took place while the final NUC-SCOPU verification was held in May, 2006. To the Glory of God, on May 17, 2007. The Federal Government of Nigeria granted probational operational License for Caleb University to operate as a private University. The University started full academic program with admission of its first set of students, a total of 83 male and 58 female students on Monday, January 7, 2008. Wikipedia.

Microbiological and Physicochemical survey was undertaken in produced water and its receiving environment with the aim of verifying the likely impacts of produced water constituents on the immediate receiving marine near shore shallow environment. The sampling was carried out in two seasons, late wet season and late dry season. The results obtained indicate that the chemical constituents of the discharged produce water are capable of sustaining microbial growth and proliferation. Produce water from Escravos tank farm had relatively moderate concentrations of hydrocarbon utilizing microorganisms and sulphate reducing bacteria and the concentration of these organisms were much higher at the point of discharge of the produced water. Physicochemical analysis showed that Produce water had lower salinity and sulphate levels than the receiving marine water but the reverse was the case with the BOD, COD and Hydrocarbon constituents. The two seasons under investigation showed similar results. From the analytical data, it can be advanced that the impacts of produced water microbial flora on the receiving environment is limited to the vicinity of the discharge point of about 100 m in diameter and also to some extent up to a distance of 500 m upstream along the direction of flow of produced water discharges. It is expected that while the hydrocarbon degrading microorganisms plays a beneficial role of degrading and detoxifying abundant produced water hydrocarbons in the sediment and the surface water, Sulphate reducing bacteria might at the same time be playing a detrimental role of oxidizing certain organic compounds or hydrogen and reducing sulphate and other reduced sulphur compounds in the marine water and sediment to hydrogen sulphide which can be very toxic to bacteria, aquatic animals and man. © 2010 Academic Journals.

Aim: The patho-physiology of pre-eclampsia is not fully understood. This study determined the plasma levels of markers of oxidative stress, thyroid hormones, nitric oxide, C-reactive protein, and nutritional profiles in pre-eclamptic patients. Methods: Thirty-two pregnant women with pre-eclampsia and 40 women with normal pregnancy (controls) participated in this study. The pre-eclamptics were recruited after 20 weeks of gestation. They presented with hypertension (systolic pressure = 169 ± 26.0 mmHg, diastolic pressure = 102 ± 11.0 mmHg), significant proteinuria (368 ± 39 mg/24 h), severe headache, abdominal pain and vomiting. The plasma levels of total antioxidant potential (TAP), total plasma peroxides (TPP), total cholesterol (TC), total protein (TP), albumin, globulin, nitric oxide (NO), C-reactive protein (CRP), total tri-iodotyronine (TT3) and thyroid stimulating hormone (TSH) were determined in them using spectrophotometry, radial immunodiffusion and enzyme linked immunosorbent assay (ELISA) methods, respectively. Oxidative stress index (OSI) was calculated as the percent ratio of TPP and TAP. Results: The weight and body mass index of pre-eclamptics increased significantly (p < 0.05) when compared with the controls. The mean systolic and diastolic blood pressure increased significantly (p < 0.001) in pre-eclamptics when compared with the controls. Plasma mean values of TAP, NO, albumin, TP and TT3 decreased significantly (p < 0.05) in pre-eclamptics when compared with the controls. The plasma mean values of TSH, TPP, OSI, CRP, and TC increased significantly (p < 0.05) in pre-eclamptics when compared with the controls. There was no significant change in the plasma value of globulin when compared with the controls. TT3 correlated positively with plasma TP and globulin in the pre-eclamptics. Conclusion: It could be concluded that hypothyroidism, hypercholesterolemia, oxidative stress and deranged inflammatory responses are possible features of pre-eclampsia. © 2013 Springer-Verlag Berlin Heidelberg.

Synthetic-based fluids (SBF), which are composed mostly of linear alpha Olephins, Esters and Paraffins are used in drilling mud to lubricate the drill bit, control reservoir pressure and bring rock chips and cuttings to the surfaces which are subsequently released into the marine environment as a residue on the cuttings as they are discharged. Aerobic biodegradation is a major criterion for selecting synthetic -based fluids for drilling mud. In the present study, sediments were collected from four different locations in the Gulf of Guinea measuring from 100- 500m depth and were used in indoor basin benthic chamber tests to measure degradation rates of 4 different Ester based synthetic fluids at room temperature over a 120 day test period. At each 30 day interval, residual organic carbons were measured by gas chromatograph while microbial populations were quantified with the most probable plate number method (MPN). At the end of the 120-day monitoring period, the following % degradation rates were recorded for the different ester based fluids used in the study; BR-EST (94%), CH-EST (91%), PFB-009 (94.8%), PFB-008 (93.8%). This result indicate that the Ester based fluids used in the experiment are readily biodegradable and the Gulf of Guinea sediments harbour considerable populations of indigenous hydrocarbon utilizing microorganisms that are capable of degrading the exogenous ester based synthetic fluids. This study addressed the fate of the synthetic ester base fluid portion of the drilling mud in Gulf of Guinea sediments by determining the potential of indigenous marine sediment microbes to degrade representative SBF under natural conditions.

Aerobic biodegradation of synthetic Paraffins and Olefins in the Gulf of Guinea sediments were monitored over a 120 day period in an indoor benthic chamber basin tests measuring 18 x 30 inches. At each 30 day interval, residual hydrocarbons were measured with gas chromatograph while microbial populations were quantified with the most probable plate number method (MPN). At the end of the 120 day monitoring period, the following % degradation rates were recorded for different hydrocarbon substrates; Linear Olefin (90%), Synthetic Paraffin (82%), and Internal Olefin (86%). The overall degradation sequence showed that the Olefins degraded faster than the Paraffins but both hydrocarbon substrates were readily biodegradable by the indigenous microbial flora of the Gulf of Guinea sediments. This study demonstrated that over 85% of the degradation of Synthetic Paraffins and Olefins on the surface of sediments were carried out by aerobic microorganisms. Source

Samples were obtained from the Obigbo field, located onshore in the Niger delta, Nigeria, from which oil is produced by injection of low-sulfate groundwater, as well as from the offshore Bonga field from which oil is produced by injection of high-sulfate (2,200 ppm) seawater, amended with 45 ppm of calcium nitrate to limit reservoir souring. Despite low concentrations of sulfate (0-7 ppm) and nitrate (0 ppm), sulfate-reducing bacteria (SRB) and heterotrophic nitrate-reducing bacteria (NRB) were present in samples from the Obigbo field. Biologically active deposits (BADs), scraped from corrosion-failed sections of a water- and of an oil-transporting pipeline (both Obigbo), had high counts of SRB and high sulfate and ferrous iron concentrations. Analysis of microbial community composition by pyrosequencing indicated anaerobic, methanogenic hydrocarbon degradation to be a dominant process in all samples from the Obigbo field, including the BADs. Samples from the Bonga field also had significant activity of SRB, as well as of heterotrophic and of sulfide-oxidizing NRB. Microbial community analysis indicated high proportions of potentially thermophilic NRB and near-absence of microbes active in methanogenic hydrocarbon degradation. Anaerobic incubation of Bonga samples with steel coupons gave moderate general corrosion rates of 0.045-0.049 mm/year, whereas near-zero general corrosion rates (0.001-0.002 mm/year) were observed with Obigbo water samples. Hence, methanogens may contribute to corrosion at Obigbo, but the low general corrosion rates cannot explain the reasons for pipeline failures in the Niger delta. A focus of future work should be on understanding the role of BADs in enhancing under-deposit pitting corrosion. © 2014 Society for Industrial Microbiology and Biotechnology. Source
