ABSTRACT Recent introduction of man-made toxic chemicals, and the massive relocation of natural materials to different environmental compartments like soil, ground water and atmosphere, has resulted in severe pressure on the self-cleansing capacity of recipient ecosystems. Various accumulated pollutants and contaminants such as polychlorinated biphenyls (PCBs) are of much concern relative to both human and ecosystem exposure and potential health impact. PCBs which are resistant to degradati...
ABSTRACT The study area, Ijesha-Ijebu falls within the Nigeria sector of the Eastern Dahomey Basin. It lies within the contact zone between the south-western basement rocks and the Eastern Dahomey Basin. The principal objective of this project work is to deduce the depositional environment and identify the formations in the study area. The field and laboratory investigation were carried out during this project work. Nineteen (19) rock samples collected were described for its: grain texture, ...
ABSTRACT The Turonian Nkalagu Formation exposed at NIGERCEM (Nigerian Cement Company) within the Lower Benue Trough was studied in this work in order to determine and establish the lithostratigraphic successions and reconstruct the paleoenvironment of the deposition. Two major litho-facies were delineated. The first is matrix-supported bioclastic shell lag wackestone facies which account for about 70% of the carbonates. The second is a massive fossil-poor micritic limestone. However, using th...
ABSTRACT The aim of the study was to assess the reported health problems associated with the burning of biomass fuel for fish smoking. A cross-sectional study was conducted from December 2016 to May 2017 among fish smokers at Abuesi in the Western Region of Ghana. A total of 434 fish smokers were selected to assess their level of knowledge of health effects associated with fish smoking as well as disease symptoms they have encountered as a result of smoking fish. Additionally, 60 smoke houses...
ABSTRACT The changing climate pattern in the Northern Regions of Ghana has influenced the movement of people, especially the youth, out of the Lawra District in the Upper West Region. Smallholder farmers that still live in the District tend to rely on remittances sent by their migrant relatives to support their livelihoods, however, little is known about how these remittances influence their adaptation processes. This study assesses smallholder farmers‘ perception on climate change and its ...
ABSTRACT The effect of different soil amendment strategies, and neem products for the management of insect pests of okra was studied in the field at the Ashaiman irrigation project site. The insect pests encountered fell into seven orders belonging to twenty-three families. The important ones among these were Aphis gossypii (Glov.), Bemesia tabaci (Genn.), Dysdercus spp. Podagrica uniformis (Jac.), Heliothis armigera (Hb.) synonym Helicoverpa armigera (Hb,), Sylepta derogata (Fab.), Anthonomu...
ABSTRACT Nuclear power plants vary based on their technology, design and material composition of the various components of the reactor. Nigeria's decision to adopt nuclear technology for power generation presents the need for comparison of the different types of nuclear power plants based on waste generation, to help in choosing which of the reactors to adopt using Open Fuel Cycle, knowing that the generation of waste during the lifetime and operation of a Nuclear Power Plant (NPP) is a point...
ABSTRACT The effect of Neem Seed Water Extract (NSWE) on insects and growth performance of eggplant (local garden egg) was evaluated in the field from June to October 1998 at Ekoso in the Eastern region, Ghana. The extract was applied at the rate of 75 g of seed per litre of water and compared with a standard insecticide (Karate), a registered Bacillus thuringiensis Berl. (Biobit) and water only as control. The effect of each treatment on leaf, shoot and fruit damage caused by defoliators, sh...
ABSTRACT Livestock are important contributors to food production in Ghana, providing meat, milk and a source of income for many. Rearing of livestock is practiced by the majority of the farming communities in which they are considered as an investment and insurance against risk and to meet seasonal and emergency purchases such as food crop, improved seed, fertilizers and medicine. However, production of animals is constrained by compound effects of parasitic infestation, diseases, poor feedin...
ABSTRACT An x-ray dose above the maximum permissible limit is harmful to human beings. A study of x-ray attenuation by materials is an important subject in protecting humans from harmful effects of radiation. Thus it is desirable to have knowledge about materials for effective x-ray shielding. Concrete is the most widely used construction material for this purpose and its composition plays an essential role in modifying the mechanical properties which affects significantly the shielding prope...
ABSTRACT In this study, the Monte Carlo N-particle simulation code MCNPX-2.6.0 was used to determine the shielding effectiveness of clay, wood and sandstone. This was done by determining the transmission of 60Co gamma and X-rays with energies 60 keV, 120 keV and 300 keV through wood, clay and sandstone. The transport computations were done for slab shield, computing half-value layers (HVLs), tenth-value layers (TVLs), buildup factors, and attenuation coefficients (both linear and mass attenua...
ABSTRACT Access to kindergarten education has increased in Ghana currently, however, due to poor monitoring and evaluation systems, standards are often compromised. This study sought to assess quality kindergarten education using one hundred and two (102) public (52) and private (63) kindergartens in the Tamale Metropolis, of Ghana. A crosssectional design with mixed method approach was used to sample one hundred and twenty (120) teachers and ten (10) head teachers from the sampled schools. T...
ABSTRACT Groundwater samples collected from 40 institutions and public boreholes within the Twifo Hemang Lower Denkyira (T), Assin North (AN) and Assin South (AS) districts of the Central Region of Ghana were assessed to determine their suitability for domestic and agricultural purposes, based primarily on recommended permissible limits for parameters stated by World Health Organisation. The area covers an area of about 4,199 km2 . The quality assessment was made through the estimation of Ca2...
Abstract Resistance to the cowpea aphid is important component of integrated pest management of cowpea cropping systems most especially at the vegetative stage. The objective of this study was to demonstrate the effectiveness of the aphid resistance locus identified in advanced breeding line SARC 1-57-2 in reducing damage from the cowpea aphid in Ghana. Using an F2 population developed from Apagbaala x SARC 1-57-2, the resistance locus was tagged with the SSR marker CP 171F/172R with a recom...
The study was conducted to determine the relationship between climatic variation and agricultural production as well as to identify their impact in Makurdi Local Government Area. The research went further to determine effective weather for livestock production in Fiidi, Wailomayo, Wadata, agan, Bar, Mbalagh, market Clark, modern market, NorthBank 1, Northbank II and Mission Wards which constitute the study area. The result shows that there is marked inter annual variations in the rainfal...
