Dynamics of groundwater flow and upwelling pressure heads at a wetland zone in a headwater catchment
(Springer Nature, 2019)The rate and direction of groundwater flow are a function of the gradient of the hydraulic head, whose components are gravity head and pressure head. This paper presents results and analyses of field observations of pressure ... -
Effect of brining on the drying rate of tilapia (Oreochromis niloticus) in a solar tunnel dryer
(Acta Press, 2008)This study determined effect of on the drying rate of tilapia in a solar tunnel dryer. Tilapia fish was split into pieces of 4cm by 3cm by 9mm and soaked into four brine concentrations varying between 0-15%. Moisture content ... -
THE EFFECT OF FINE NON-METALLIC INCLUSIONS ON THE FATIGUE STRENGTH OF STRUCTURAL STEEL
(2015)The article discusses the results of a study investigating the effect of the number of fine non-metallic inclusions (up to2μm in size) on the fatigue strength of structural steel during rotary bending. The study was performed ... -
Effect of harvest age and thermal processing on poly-γ-glutamate folates and minerals in African cowpea leaves (Vigna unguiculata)
(Elsevier, 2012-03)Cowpea leaves (Vigna unguiculata) are highly consumed in Africa because the plant is easy to cultivate and highly disease/drought tolerant. The vegetables are harvested between 4 and 9 weeks of maturity. The objectives of ... -
Effect of Peripheral Velocity Difference Ratio on the Performance of Rubber Roll Huske
(The Japanese Society of Agricultural Machinery and Food Engineers, 2000)The difference in speed between the rubber rolls results in a shearing action on the rice grain as it passes between the rolls (Yamashita et al 1990, FA, 1995). The shearing force is thus dependent on the relative velocity ... -
Effects of Distributed Generation penetration on system power losses and voltage profiles
(International Journal of Scientific and Research Publication, 2013)In present times, the use of DG systems in large amounts in different power distribution systems has become very popular and is growing on with fast speed. Although it is considered that DG reduces losses and improves ... -
Effects of mildly heated, slightly acidic electrolyzed water on the disinfection and physicochemical properties of sliced carrot
(Elsevier, 2013)The efficacy of mildly heated, slightly acidic electrolyzed water (mildly heated SlAEW) at 45 °C for disinfection and maintenance of sliced carrot quality was studied. Mildly heated SlAEW (23 mg/L available chlorine, pH ... -
Effects of Polarization Mode Dispersion (PMD) on Raman Gain and PMD Measurement using an Optical Fibre Raman Amplifier
(IEEE, 2013-09-09)We experimentally investigate the effects of increase of the differential group delay (DGD) on Raman gain and gain value. It was found that the increase of DGD values lead to the formation and the increase in the number ... -
Emission Constrained Economic Dispatch Using Moth Flame Optimization and Bat Hybrid Algorithm
(International Journal of Engineering Research and Technology, 2018)This paper presents the application of a novel Moth flame optimization and Bat hybrid algorithm in the area of emission constrained economic dispatch with the main goal of minimizing the total cost of electric generation ... -
Enhancing household food and income securitythrough crop diversification in the Nzoia and Mumiassugarbelts in Kenya
(FACT Limited, 2009)Objective: Competition for land use among crops in the Nzoia and Mumias sugar belts hastened to favour sugarcane and maize at the expense of indigenous food crops such as onions, tomatoes, cassava and sweet ... -
Enhancing production through optimisation of DPPH and radical scavenging activity of grape seed extracts
(African Crop Science Society (Uganda), 2014)Polyphenols are important for their pharmacological activity and positive contribution to cellular processes within the body. They have the capacity to protect against oxidation of High Density Lipids (HDL) and, thus help ... -
Evaluation of Kenyan Bentonite Clay as Geothermal Well Drilling Mud
(2015)The quest for the development of geothermal plants with capacities up to 10,000 MWe in Kenya has recently placed greater demand on bentonite clay. Bentonite clay is at present largely imported into the country at the ... -
Evaluation of Solar-Energy Dryer Systems on Drying Behaviour and Quality Attributes of Amaranth Grains
(Science and Engineering Publishing Company, 2012)This work aimed at evaluating the thin layer drying behaviour of amaranth grains (Amaranthus cruentus) and comparing the quality of the grains dried under solar-energy tent dryer systems and the open sun. The dryers were ... -
Evaluation of the antimicrobial and antioxidant properties of extracts of Mondia whytei roots extracts
(Galati University Press, 2011)Extracts of Mondia whytei (M. whytei) root barks were screened for their inhibitory effects against Staphylococcus aureus (S. aureus) (ATCC 25923), Escherichia coli (E. coli) 0157:H7 (PSSCMI 0032), ... -
An experimental prototype for low head small hydro power generation using hydram
(2013)The global rise in energy demand has resulted to the over exploitation of both renewable and non renewable energy sources. Most feasible hydroelectric power (HEP) plants sites have been exploited and the current ... -
