In this study, the effects of methanol-to-oil molar ratio, catalyst amount and reaction time on the transesterification of waste cooking oil (WCO) to biodiesel were investigated. Methanol with calcium oxide as a heterogeneous catalyst was used for the transesterification process...
The present investigation was conducted to study the effects of different concentrations of picloram on somatic embryogenesis induction, development and maturation of three strawberry (Kurdistan, Paros and Camarosa) cultivars. For this purpose, leaf blade, nodal, petiole, stamen...

In Benin, the use of synthetic pesticides in vegetable production poses a risk to the environment and human health. Vegetables, water and soil quality assessment is very important for monitoring and mitigation of these risks. The evaluation of pesticide contamination of vegetable...
The present study investigated the role of soil pH adjustments in heavy metals concentrations in waste engine oil (WEO) - polluted soils. Sun-dried top soil (0-10cm) was measured into buckets. WEO was added to soil and mixed thoroughly to obtain similar concentrations of 2.5% w/w...
Molecular microbiology techniques have revolutionized microbial ecology by paving the way for rapid, high-throughput methods for culture-independent assessment and exploitation of microbial communities present in complex ecosystems like crude-oil/hydrocarbon polluted soil. The so...
Aims: To assess the effects of initiating antihypertensive therapy with amlodipine (AML) or hydrochlorothiazide (HCZ) for 48 weeks on creatinine clearance (Clcr) in hypertensive Nigerians with type 2 diabetes mellitus (DM). Study Design: Randomized, open-label, prospective, outpa...
Endo-1, 4-β-xylanase (Endo-β-1, 4-xylan, xylanohydrolase; EC. 3.2.1.8, commonly called xylanase) is an industrially important enzyme which degrades xylan randomly and produces xylooligosaccharides, xylobiose and xylose. It is mainly present in microbes and plants but not in anima...
Fifteen genotypes of pearl millet (Pennisetum glaucum L. R. Br.) were evaluated at Sudan University of Science and Technology, The Demonstration Farm, College of Agricultural Studies, Shambat, during the summer season 2009 and 2010. The present study was conducted to assess the m...
In order to make organic fertilizer more quantifiable and attractive to farmers, a pelletizing machine was fabricated locally to produce pellets from powdery fertilizer. However, concerns have been raised on the potential impacts this process could have on the quality of organic...
Aims: To elucidate the effect of estrogen and folic acid on high fat (butter) induced lipid profile (total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), and triglyceride (TG)) and on tissue texture changes in mice. Designs: Randomized block desi...
Aims: The objective of the work is to remove Pb2+ by Pleurotus florida and Trichoderma viride in batch studies and to study the kinetics and adsorption isotherm of Pb2+ adsorption by fungal species and to determine the desorption performance by suitable desorbing agents. Study D...
Present research was aimed towards designing and construction of efficient plastic media-trickling filter (TF) for the treatment of domestic wastewater. The hydraulic flow rate through the TF was maintained at 80±2 ml/min at a temperature range of 5-15ºC by selecting treatment ti...
Aims: The present study aimed to evaluate and ascertain the protective role of methanolic/ethanolic/water extracts of Convolvulus pluricaulis against H2O2 induced cytotoxicity in IMR32 Neuroblastoma cell line as model system and identify the factor responsible for the protective...
The evaluation of selection criteria using correlation coefficients, multiple regression and path analysis was carried out for a period of two years on sixteen genotypes of rice (Oryza sativa L.).These genotypes were studied during 2008 and 2009 summer seasons at EDduim and Kosti...
Aims: To identify putative Vibrio isolates obtained from processed hake, pilchards and horse mackerel using Thiosulphate-Citrate-Bile-Sucrose (TCBS) agar. Place and Duration of Study: Sampling during April – June 2005 in Walvis Bay Namibia. Further analyses performed at the Depar...
