Optimal Sizing and Analysis of a Hybrid Energy System for a Community Microgrid in Nigeria
(Medwell Journals, 2019)This study focuses on determining the optimal size of each component of a hybrid energy system to meet the energy demand of Itele community in Nigeria at minimum Net Present Cost (NPC). The hybrid energy system consists ... -
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 ... -
Influence of Brining on the Drying Parameters of Tilapia (Oreochromis Niloticus)in a Glass-Covered Solar Tunnel Dryer
(2009)The objective of this study was to determine the effect of brining on the drying rate of tilapia (Oreochromis niloticus) in a glass-covered solar tunnel dryer. Tilapia fish, eviscerated, and split into pieces ... -
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), ... -
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 ... -
The contribution of Framed Chainsaw System to Improvement of Sawn Timber Quality
(International Journal of Current Research, 2013)In this study, the effect of framed chain sawing system with optimized chain on timber size uniformity and surface roughness was analyzed and compared with the freehand chainsaw system and band saw as control. The surface ... -
Simulation model for solar energy harnessing by the solar tunnel dryer
(2010)Models were developed to predict global solar radiation and the energy harnessed by a solar tunnel dryer, and simulated in Visual Basic 6. In addition, the simulated data were compared with actual data. Using a 10% absolute ... -
Husking Characteristics of Short and Long grain Rice byRubber roll Husker (Part 1): Dynamic Analysis of a Single Grain Motion
(The Japanese Society of Agricultural Machinery and Food Engineers, 2001)Dynamic analysis of grain motion in an experimental rubber roll husker was carried out using short and long grain rice. The short grain rice variety used was Akitakomachi and the long grain rice varieties were Delta and ... -
Properties of Prosopis juliflora and its potential uses in ASAL areas of Kenya
(2013)A study was done to determine the potential for processing and using prosopis juliflora for commercial purpose. The effects of the plant on the soil were evaluated as a measure of determining its influence on the environment. ... -
Performance Characteristics of Blended Rice Bran Biodiesel In aDiesel Engine
(2013)Rice bran is a by-product of the rice milling process and contains 10–25% oil depending on rice variety, milling procedure, and other agro-climatic factors. To supplement the dwindling fossil ... -
Modeling Thin Layer Drying of Amaranth Seeds under Open Sun and Natural Convection Solar Tent Dryer
(2009)Thin layer drying studies of amaranth (Amaranthus cruentus) seeds were carried out under open sun and natural convection solar tent dryer. The ambient temperature and relative humidity ranged from 22.6–30.4 ... -
Drying characteristics and some quality attributes of Rastrineobola argentea (Omena) and Stolephorus delicatulus (Kimarawali)
(AFRICAN SCHOLARLY SCIENCE COMMUNICATIONS TRUST, 2010)Rastrineobola argentea common name Omena and Stolephorus delicatulus common name Kimarawali are fishes that live in the freshwater and marine waters, respectively. Both are small in size, move in ... -
Performance Analysis of an Impeller Husker considering the Physicaland Mechanical Properties of Paddy Rice
(Academic Press, 2001)Some physical and mechanical properties of three varieties of rice namely; Akitakomachi (short grain), Delta and L201 (long grain) were determined and used in the performance analysis of an impeller husker. Grain motion ... -
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 ... -
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 ... -
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 ... -
Dynamics of groundwater flow and upwelling pressure heads at a wetland zone in a headwater catchment
