Journal of Asian Scientific Research , 2012,
Abstract: The antibacterial and antifungal activity of Garcinia kola of small and large seeds varieties were extracted in ethanol and water (cold and hot) and tested against some selected clinical bacterial and fungal isolates; Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis and Pseudomonas aeruginosa at concentrations of 10, 20, and 30 mg/ml. The same concentrations were used against the fungi Candida albicans and Aspergillus niger. Agar well diffusion method was employed to determine the antimicrobial activity of the extracts against test microorganisms. The results showed that the small seed ethanol and aqueous (hot water) extracts exhibited more antimicrobial activity at a concentration of 30 mg/ml, with zones of inhibition ranging from 17 to 23mm for ethanol. The aqueous (hot water) extracts showed zones of inhibition ranging from 20 to 27mm. The extracts also showed antifungal activity against Aspergillus niger. The minimum inhibitory concentration (MIC) showed antimicrobial activity at lowest concentration of 0.008mg/ml and maximum concentration of 5.0mg/ml against Staphylococcus aureus. There were presence of phytochemical compounds such as flavonoids, tannins, saponins, steroids, cardiac glycosides, and reducing sugars. The results imply that the ethanol and aqueous extracts of Garcinia kola seed posses strong antibacterial and antifungal properties when compared with standard antibiotics amoxicillin; ciproxin; tetracycline and streptomycin used during the investigation, and hence its potential as a useful chemotherapeutic agent in the treatment of bacterial and fungal infections in humans.

Journal of Food Technology in Africa , 2002,
Abstract: Kunun-zaki was produced from millet (Pennisetum typhodeum), sorghum (Sorghum bicolor) or maize (Zea mays) with or without the addition of hydrolytic enzymes obtained from ground-malted rice (Oryza sativa FARO 37) and analyzed for its chemical and organoleptic quality attributes. The results obtained show that there were 33, 44, 66% increases in crude protein 52, 117 and 91% increases in sucrose contents in those products (i.e. kunun-zaki produced from millet, sorghum and maize respectively) in which the extracts from ground-malted rice were incorporated. A similar increase was observed in acidity, iron, calcium and phosphorus contents. Furthermore, the sensory attributes of kunun-zaki produced using extracts from ground-malted rice did not differ (p>0.05) from the other products in appearance, taste, texture and sensory overall acceptability but differed (p<0.05) in aroma, which could be attributed to the production of more organic acids in these products by the fermenting microorganisms. The result obtained in this study therefore suggests that it could be economical and nutritious to use malted cereal grains in the production of kunun-zaki.

Vorobets, M.O;
Revista mexicana de física , 2010,
Abstract: barrier structures were produced using optical contact between the indium and gallium selenides. the effect of mechanical pressure ranging from 0 to 100 kpa on the electrical properties of the gase/inse heterocontacts was investigated. the data was analyzed assuming the sis (semiconductor - insulator - semiconductor) model. using this model we were able to explain the current - voltage dependence. it was found that the modification of heteroboundary significantly affects the electric transport.
PARASITIC INFECTIONS OF DRY SEASON FARMERS IN SOME PARTS OF PLATEAU STATE, NIGERIA
M.O. Okoronkwo
African Journal of Clinical and Experimental Microbiology , 2002,
Abstract: A parasitological survey was conducted among 1080 dry season farmers and controls spread over nine farming locations in the Jos and Barkin-Ladi areas of Plateau State, Nigeria, to provide data or parasitic infections in the area due to waste utilization. Standard laboratory procedures were adopted in the collection, processing and parasite identification in the stool samples. The rates of parasites infections in the farmers were 91.6% for helminthes and 86.4% for protozoa. Helminth infection rates but not those of protozoa, varied significantly between farmers and controls. Average infection rates were. Ancylostoma duodenale 91.9%. Ascaris lumbricoides 84.7%, Trichuris trichiura 74.2%, Strongyloides stercoralis 50.3%, Giardia lamblia 13.3%, Entamoeba coli 28.4%, Chilomastix mesnili 15.4%, Endolimax nana 17.3%, Isospora belli 6.3% and Lodoamoeba butshkii 11.5%. More males than females were infected. The rates of infection varied among farmers in the different locations, but younger farmers had higher prevalences. Significant correlations between infections and their symptoms were observed with diarrhoea and abdominal pains being most common. (Af.

Emancipating Women Through Technological Empowerment: Aid to Sustainable Development
M.O. Asokhia
Asian Journal of Information Technology , 2012,
Abstract: The study looked at how the knowledge and positive involvement of women in Information Communication Technology (ICT) can assist in emancipating them. Women are integral part of the population that a country needs in development. However, the women of Nigeria for a long time in the history of the nation s development have not been given their right of place. Information Communication Technology is a potent tool in meeting human basic needs. Unfortunately, the women that are the fulcrum on which development depends do not have good exposure to ICT. The study highlighted some of the problems inhibiting women s effective participation and proffered useful solutions that will assist them in being fully functioning in the use of Information Communication Technology.
Socio-Cultural Practices Promoting the Transmission of Urinary Schistosomiasis among School Aged Pupils in a South Western Village in Nigeria
M.O. Oniya
Research Journal of Biological Sciences , 2012,
Abstract: Studies were carried out on the epidemiology of urinary schistosomiasis among school-aged pupils in a Nigerian Village endemic for the disease. Prevalence of infection as at the time of survey was 59% and results obtained via questionnaire administration on socio-cultural practices promoting transmission revealed that there was a dearth of information about the aetiology and transmission of the disease, which still remained the major public health problem in the community. Increased community based education by qualified personnel and committed control measures against parasite and snail host over a long term basis, were identified form this study as probable methods of eradicating the scourge.
Comparison of Various Fatty Acid Sources for Making Soft Soap (Part 1): Qualitative Analysis
M.O. Edoga
Journal of Engineering and Applied Sciences , 2012,
Abstract: This study compared the various fatty acid sources for making toilet soap via conventional method. These included palm oil, Palm Kernel Oil (PKO), groundnut oil and tallow fat. The toilet soap samples were developed using hot batch process by reacting 16.8 g caustic potash with 50 g oils/fats. The mixture was continuously stirred via electrically operated mechanical stirrer for 25-30 min. Later, 20 g of water was added to the system to break-up the foams, as well as aid the saponification process. Stirring was continued for 40-60 min, after which the salting process was carried out by adding the mixture to a solution of saturated sodium chloride. Also, stirring continued until the paste became thicker thereafter the reaction was stopped and was allowed to stand for several hours to cool and solidify. Analysis of the various soap samples was carried out to test for formability, corrosiveness, hardness, pH, rate of wear, acid value, saponification value and iodine value. Formability and corrosiveness results obtained are as follows: 9.90 cm for palm oil, 10.70 cm for (PKO), 10.74 cm for groundnut oil and 11.58 cm for tallow fat and 2.76% free alkaline for palm oil, 2.62% free alkaline for PKO, 2.60% free alkaline for groundnut and 2.52% free alkaline for tallow fat soap, respectively. The pH values are also given as 11.63 for palm oil-based soap, 11.0 for PKO-based, 10.30 for groundnut oil-based and 10.46 tallow oil-based soap.

M.O. Ofomola
Journal of Engineering and Applied Sciences , 2012, DOI: 10.3923/jeasci.2011.231.236
Abstract: The uphole refraction survey was carried out in YOM field 4-D prospect to evaluate the weathering thickness and velocity of the Low Velocity Layer (LVL). Five uphole locations were occupied in the study area and the time intercept technique of the seismic refraction interpretation was employed. For the different locations (A-E), the weathering thickness was found to vary from 0.9-1.9 m with velocity from 250-800 m sec-1. A sub weathering layer was also observed in all locations except A. Also, the velocity of the consolidated layer was found to vary from about 1750-1800 m sec-1 with a mean velocity of 1766 m sec-1. Using this result to eliminate the effect of LVL on reflection data from the graphical approach, it was observed that the elevation and weathering correction (static correction) was found to be eliminated at a datum of 2 m deep.

M.O. Durowoju
Journal of Engineering and Applied Sciences , 2012,
Abstract: Fractal analysis was used to observe the size, shape and distribution of pores in Al-V2O5 mechanically alloyed composite. The analysis reveals that the pores are of irregular shapes, i.e shrinkage pores, with sphericity < 0.3.The `worst` of the shapes is the pore with = 1.0254e-009 and D = 1.8541, while the `best` shape is the pore with = 4.8309e-004 and D = 1.6521. Also, the graph of against D shows that as decreases the D values increases. This is in agreement with the theoretical background.
Economics of Maize Storage Techniques by Farmers in Kwara State, Nigeria
M.O. Adetunji
Pakistan Journal of Social Sciences , 2012,
Abstract: Maize Storage Technologies (MST) are diverse among farmers and these variations have economic implications, this study, therefore, examines the benefit of using various Storage Techniques (MST) in Kwara State. Multi-stage sampling technique was used to choose 8 local government areas from the four zones, five villages were selected from each LGA. One hundred and eighty eight maize farmers were selected using probability proportionate to number of farmers in each village as contained in the ADP household lists. Structured questionnaires covering socio economic characteristics, quantity of maize stored, types of storage, length of storage, cost and returns on the use of storage were administered to the maize farmers. Descriptive, budgetary, partial budget analysis and multinomial logit regression were used to analyse the data. Three maize storage techniques being used by the respondents were: Local Storage (LS), Semi Modern Storage (SMS) and Modern Storage(MS). Among maize farmers, 37.9, 20.7 and 10.6% used LS, SMS and MS, respectively, while 30.8% did not store their maize. The gross margin for using various storage technique were N8,345/t (LS), N11,135/t (SMS), N12,435/t (MS). The modern storage had the highest incremental gross margin (N8,135/t), compared with the control (i.e., no storage). The result from partial budgeting and marginal analysis shows that modern storage techniques is the best because it has the highest difference in gross margin and highest marginal rate of return. Multinomial logit model results reveal the odds of using different storage techniques by farmers. It could be seen that rise in transportation cost, labour cost and farmers household size enhance the probability of using no storage. The probability of using local storage is enhanced by farmer s age, semi modern is likely influenced by quantity of maize stored, while the probability of using modern storage is increased by years of experience, educational level of the farmers and quantity of maize stored by the farmer. Modern storage technology usage, improvement in literacy level and large quantity of maize stored would enhance farmers income.
