ABSTRACT The study examined the role of anthropogenic disturbances, temperature, precipitation and evapotranspiration in the range shift of aquatic plants, fish and bird communities in six wetlands. It was conducted over a 2-year period. The dominance ratio approach was used to determine the range shift of plants. Ordination techniques were used to determine the influence of environmental factors on biological data-set. Of the 40 species of plants sampled, obligate species constituted 35%, wh...
ABSTRACT This research work focused on the effect of climate change on cocoa yield in some selected cocoa districts in the Eastern, Ashanti, Western and Central Regions of Ghana. For sustainable cocoa production, weather, which is an uncontrollable variable, is an important factor whose effect on cocoa is difficult to quantify in a field environment. This research has two components; effects of climate change on cocoa production in Ghana and coping strategies of cocoa farmers. The Heckman’s...
ABSTRACT The total investment cost of a pipeline network to transport carbon dioxide (CO2) from power plants for enhanced-oil-recovery (EOR) in oil fields in Texas Gulf Coast as CO2 mitigation has been estimated. The impact of the CO2 capture and transport on power generation cost, including the benefits of atmospheric CO2 mitigation has also been determined. 14 power plants comprising 55.7% of installed capacity in Texas Gulf Coast were selected. Geographical-informationsystem was used to op...

ABSTRACT Bambara nut was subjected to different treatments prior to mechanical dry dehulling and milling into flours. Physicochemical properties of the flours and sensory attributes of moin-moin prepared from the flours were compared with that of moin-moin from fresh pastes from cowpea and Bambara. The functional properties investigated included foam-ability, foam-stability, gelation capacity, dispersibility and dehull-ability while proximate chemical composition of the flours was also invest...
Abstract Terms Similarity (TS) in retrieval systems are based on lexical matching, which determines if query terms are useful and reflect the users‟ information need in related domains. Existing works on TS use Term Frequency-Inverse Document Frequency (TF-IDF) to determine the occurrence of terms in web documents (snippets) is incapable of capturing the problem of semantic language mismatch. This study was designed to develop a conceptual knowledge model to solve the problem of TS in web ...
ABSTRACT The ionospheric phase refractive index is a complex function that determines the attenuation and the trajectory of radio signals through the ionosphere. This complex refractive index model has been obtained using the Maxwell's equations, the tensorial conductivity equation, electron collision models, and the geomagnetic field model. The model has been used to study and investigate the phase refractive index on radio wave propagation for high latitude, low latitude and equatorial regi...
ABSTRACT Teaching is becoming one of the most challenging professions in our society. Knowledge is expanding rapidly and modern technology is demanding teachers and students to use technologies in teaching and learning. The study compared the students from two schools; the schools with computers and other schools without computers. Data for this study were collected by performance test and interview in Methodist Senior High School and Istiqarma Senior High School both in Wenchi Municipality. ...
ABSTRACT Watermelon fruits and soil samples (depth of 0 – 20 cm) were analysed for pesticide residues. Residues were extracted from 10.0 g of watermelon fruit using a multi-residue method for extracting pesticides from non fatty foods with acetone as the extracting solvent. Soil and okro from a nearby okro farm which were used as control to study the effect of pesticides on non target crops were also analysed. Extract clean up was done using a 10 mm chromatographic column with a 1:1 solvent...
Abstract This study was conducted to investigate effects of extrusion conditions on physicchemical properties of blend of yam and bambara nut flours. Blend of white yam grit (750 pm) and Bambara nut flour (500 pm) in ratio 4: 1 respectively was extrusion cooked at varying screw speeds 50-70rpm, feed moisture 12.5-17.5% (dry basis) and barrel temperatures 130-150 OC. Extrusion variables employed included barrel temperature (BT), screw speed (SS) and feed moisture content (FM), while physico-c...
ABSTRACT Greenhouse gases emitted from burnt fossil fuels are major contributors to global warming which currently threatens existence of life. Hence, the global campaign for the replacement of fossil fuels with solar energy. The Cu2ZnSnS4 (CZTS) thin film has emerged as a promising material for photovoltaic absorption layer in the fabrication of solar cells. Various methods of deposition have been used to fabricate superstrate CZTS thin film solar cells. However, there is limited informatio...
ABSTRACT The study investigated challenges of integrating information and communication technology (ICT) in basic schools of the Cape Coast metropolis in the Central Region of Ghana. The purpose of the study was to find out ICT resources available for use in Basic schools, ICT resources teachers actually use, ICT skills teachers have, factors that militate against the use of ICT in teaching and learning of various subjects, and possible solutions to the challenges of integrating ICT in teach...
ABSTRACT Radiological analysis was carried out on fish, crustacean and sediment samples collected from both fresh and marine water of river Igbokoda in the coastal area of Ondo State, Nigeria. The activity concentrations of radionuclides were determined using gamma spectrometry method. The means of the annual effective ingestion dose varied between 23.3 ± 10.2μSv.y-1 (OreochromisniloticusandGymnarchusniloticus) and 34.8 ± 1.7 μSv.y-1 (Parachnnaobscura) for fresh water fish samples and 6....
ABSTRACT My motivation to embark on this project work was triggered by the academic performance of the students in St. Joseph Senior High Secondary/Technical. The main objectives of this study were to compare the performance of male and female students, use principal components to determine indices for ranking the students in descending order. The Data used in the analysis were sourced from the students’ of St. Joseph Senior High Secondary/Technical third term terminal examination results...
Abstract Background: The most common cause of anemia is a deficiency of iron; but it may also be caused by deficiencies of folates, vitamin B12 and protein. Some anemias are not caused by nutritional factors, but by congenital factors and parasitic diseases such as malaria. This study attempted to estimate the prevalence of anemia among pre-school and school- aged children in two rural areas of Odogbolu Local government area, and to determine whether its cause was nutritional or could be att...
