ABSTRACT Twenty (20) accessions of hot pepper (Capsicum spp L.) were collected from eight geographical regions of Ghana for genetic diversity studies. The objective was to assess genetic relationship among them using phenotypic and molecular traits and to evaluate their elemental composition. A replicated field experiment was conducted to assess their genetic diversity based on 13 quantative traits and 22 qualitative traits using the IBPGR descriptor list for Capsicum. Confirmation of their i...
ABSTRACT Operational power of a nuclear reactor core is limited by thermal considerations. In principle, the allowable core power is restricted by the rate at which the heat can be transferred from the fuel to the coolant. Unlike in conventional combustion facilities where the heat is released in gas-flows, heat in the nuclear reactor core is mainly released in the structural material. If not properly removed the structural materials inevitably melt causing release of radioactive material. ST...
ABSTRACT The Paboase deposit located in the Chirano gold district is hosted in Paleoproterozoic rocks within the Sefwi-Bibiani volcanic belt of the Birimian, which has been regionally metamorphosed to greenschist facies. Gold mineralization at Paboase is largely hosted by albite-pyrite-carbonate altered mafic and porphyry intrusive rocks rather than Birimian sedimentary rocks and graphitic shear zones which are well known style of mineralization in southwest Ghana. Multi-element geochemistry ...
ABSTRACT Sweet potato (Ipomoea batatas Lam.) is a staple food crop for a large proportion of the population in sub-Saharan Africa. One important factor limiting its production and utilisation is infestation by weevils belonging to the genus Cylas, commonly known as sweetpotato weevils. The use of host plant resistance is an essential component for the integrated pest management of sweetpotato weevils. In this study, the susceptibility of some Ghanaian sweet potato varieties to infestations by...
ABSTRACT Organic nutrient sources such as compost could be used to improve the low fertility of tropical soils as it has the potential to enhance soil physical, chemical and biological properties and improve growth, yield and quality of crops. Pot and field experiments were conducted to investigate the effect of compost on growth, yield and nutritional quality of okra, Abelmoschus esculentus (L.) Moench. The pot experiment was done using the Completely Randomized design while field trial was ...
ABSTRACT Gas–liquid bubbly flows are commonly encountered in many industrial processes. In many cases, the evolution of bubble size distribution is a crucial factor governing the momentum, heat and mass transfer between phases within the system. In this thesis, numerical investigation of gas-liquid bubbly flows is achieved by coupling a population balance model with the three-dimensional, two-fluid model. With the aim of evaluating the capabilities of the population balance model, a model v...

ABSTRACT The study assessed the impact of an operating Tailings Storage Facility (TSF) of Adamus Resources Limited (Nzema Gold Mine) in the Ellembele District, Western Ghana, on catchment surface and groundwater quality. Water samples were collected between June and December 2014 from seventeen (17) sampling sites including the TSF decant water (TSF-DW), three (3) streams, a water storage dam, a pond and eleven (11) groundwater monitoring boreholes within 500m radius of the mine’s Tailings ...
ABSTRACT Agricultural waste can be processed under pyrolysis to generate energy for cooking, resulting in a byproduct called biochar. Biochar has the potential to be used as a soil amendment but this facility has not been explored by researchers. Unpelletized corn cob and oil palm press were subjected to water boiling test, burning duration test, biomass consumption rate, biochar yield, pH of residual water and flame characteristics using Lucia stove. The results generally indicated that corn...
ABSTRACT The construction of the Akosombo and Kpong dams have led to a change in the watershed ecology which has in turn contributed to the change in land use and land cover of the Lower Volta Basin (LVB). Inevitable changing global climate has also played a role in the alteration of land cover and crop production which have affected livelihoods. In this study, a post-classification comparison change detection algorithm was used to determine changes in land use and land cover that have taken ...
ABSTRACT Changes in river flows for hydro-electric power generation, agricultural purposes and water conservation, and other land use changes have had major ecological, social and economic consequences, which include but are not limited to disasters. The poor who mainly live in rural areas directly depend on most of these ecosystems and the services they provide for their livelihood, and so are more vulnerable to changes in ecosystems. This study was carried out to identify communities in the...
This study was carried out with the aim of assessing the rattle tree (Albizia lebbeck) effects on soil properties and Irish potato (Solanum tuberosum) productivity on the Jos Plateau, Nigeria. In carrying out the research, a randomized complete block design (RCBD) was employed consisting of five treatments and three replicates. The five treatments applied were as follows: Treatment 1 (T1): Irish potato planted in the alley (space) between A. lebbeck tree rows without green manure; T2: P...
ABSTARCT A seismological and geological investigation for earthquake hazard in the Greater Accra Metropolitan Area was undertaken. The research was aimed at employing a mathematical model to estimate the seismic stress for the study area by generating a complete, unified and harmonized earthquake catalogue spanning 1615 to 2012. Seismic events were sourced from Leydecker, G. and P. Amponsah, (1986), Ambraseys and Adams, (1986), Amponsah (2008), Geological Survey Department, Accra, Ghana, Ampo...

ABSTRACT The biodiversity conservation projects that were implemented at Gomoa Okyereko and Gomoa Adam in Gomoa East and Gomoa West Districts in the Central Region were to conserve degraded forests in the two communities. The main problems had to do with using chemicals in hunting of wildlife, regular bush fires, pollution of water bodies, indiscriminate cutting of trees and frequent wind damages. This study therefore assessed the impact of the project intervention in the light of the problem...
