ABSTRACT Stagnation-point flow of an electrically conducting fluid over a continuously stretching surface in presence of magnetic fields is significant in many industrial processes such as the metallurgy, polymer processing, glass blowing, filaments drawn through quiescent electrically conducting fluid subject to magnetic fields, cooling of metallic plate, hot rolling, wire drawing, aerodynamic extrusion of plastic sheets, crystal growing. In these applications of stagnation point flow, the d...
ABSTRACT Nutritional quality of market samples of some fruit drinks were assessed through laboratory analysis. The assessment covered the determination of quality parameters of six brands of fruits drinks which include California brands of orange and pineapple drinks, orange and pineapple fruta drinks and 5 – alive orange and pineapple drinks. The assessment indices included the determination of proximate compositions, mineral composition and vitamin composition of the drinks. From the res...
ABSTRACT Liberalization of Telecommunication Industry was established in 2001 by the Olusegun Obasanjo administration and since then, it is a common knowledge that Nigeria’s Tele-density have improved. However, it is the researcher’s intention to put this level of improvement in quantifiable terms vis-a-viz certain factors and distribution pattern. This study span for ten years [2001-2011] and four leading telecommunication firms were selected to represent the entire Telecommunication In...
ABSTRACT Soybean is one of the most important sources of protein and vegetable oil in the world. The demand for soybeans in Kenya is high yet production is negligible due to various challenges, one of which is lack of a well-organized soybean seed system. Soybean seed has been known to deteriorate rapidly in the tropics but the rates vary with the environment, initial quality of the seed and genotype. The broad objective of the research was to enhance soybean seed longevity and vigor through ...
ABSTRACT Fault seal analysis in fault dependent reservoirs were carried out at different reservoir levels in the Baka Field, Niger Delta. These involved stratigraphic correlation, 3-D seismic interpretation of faults and horizons, time-depth conversion of all interpreted faults and structural maps using both check-shot and synthetic seismogram. Also, static models of all interpreted reservoir levels, and 3-D deterministic and stochastic fault seal integrity models were carried out. The deter...
ABSTRACT Some selected tropical root and stem tubers (cassava, cocoyam, sweet potato and yam) were dried and processed into flours. The cassava tuber was processed into flour using the high quality grading method. Bambara groundnut was processed to obtain the conventional bambara groundnut flour, bambara groundnut cotyledon flour and the steamed bambara groundnut cotyledon flour. Composite flours were formulated using each of the root tubers and each of the bambara groundnut treatments in th...
ABSTRACT The antimicrobial activities and preservative potentials of crude plant extracts of stem bark of Alstonia boonei, leaves of Euphorbia hirta and seeds of Moringa oleifera were studied. Soxhlet extraction method and cold ethanol extraction method were used for the extraction of the dried and ground plant samples. The well in agar diffusion method was used for the antibacterial screening at different concentrations of 25mg/ml, 50mg/ml, 100mg/ml and 200mg/ml on Eschericia coli, Bacillus...
ABSTRACT Fisheries in the East Africa region have suffered due to less emphasis given to some fishery specifically Dagaa (Rastrineobolaargentea), whose quantity is the highest of all the species in the Lake Victoria. Despite the importance of this resource in Kenya, there has been a concern of gender parity and inequality in terms of roles played by both gender in harvesting, processing, trading and marketing in the Dagaa fishery. This study analyzed gender roles in Dagaa Fishery Value Chain ...
ABSTRACT High adult mortality due to various causes like HIV and AIDS has led to an upward trend of the number of orphans and vulnerable children. Extended family networks have taken the responsibility of caring for these children but lack of adequate resources for their care has forced the caretakers of these children to take them to orphanages. As a consequence to the ever-increasing number of orphans, there has been mushrooming of orphanages in the country. Appropriate childcare practices ...
Weed infestation is one of the major biotic constraints in wheat production. Wheat is infested withdiverse type of weed flora, as it is grown under diverse agro climatic conditions, different cropping sequence, andtillage and irrigation regimes. For controlling weeds in wheat, growers mostly rely on herbicides due to cost and timeeffectiveness. For control of diverse weed flora in wheat combination of herbicides or as sequential, if not compatibleare required. However, sole dependence on herb...
ABSTRACT Ground gravity survey covering an area of 60km2 in Kimachia and Mbeu, area of Tigania- West Sub-County of Meru County, Kenya was conducted to establish iron ore extent in the area. A Sodin 410 gravimeter was used to measure the gravity field‟s variations in the 278 established stations. At each station the location coordinates and elevation were obtained using Global Positioning System, Garmin 45 model. The time of measurement at each station was also recorded. Gravity reducti...
Abstract Resistance to drugs especially antibiotics has become a major challenge facing the medical fraternity today. Most antibiotics that were once effective against pathogenic micro-organisms have now been rendered ineffective owing to resistance developed by these pathogens. This scenario has been complicated by the emergence of HIV/AIDS, which renders the victims immuno-compromised, and open to opportunistic infections. At the same time, most of the African population lives below the pov...
ABSTRACT To Plagiarise is to include another person’s work, idea, method or results without due acknowledgement. In this work, we developed an innovative algorithm to detect external plagiarism in documents, using a combination of Word-n-gram and string matching technique. The suspicious document was split into sentences and further split into word n-gram and each n-gram was used to perform a pattern match on a standard PAN-09 corpora. We discovered that the best plagiarism detection occur...
ABSTRACT There is a growing increase in biofuel consumption around the world. Currently there is a desire to enhance biodiesel and biodiesel blends properties by use of multifunctional additives. This project sought to evaluate the miscibility of fatty acid ethyl ester blends from algae and Jatropha curcas L. oils and also synthesise hydrogenated and oxygenated derivatives of d-limonene as potential additives. Sampling of citrus peels was done from Milly Fruit Processors and Kongowea Mombasa....
