ABSTRACT The aim of this study was to determine the resting behaviour and factors that influence the choice of resting sites by endophilic anopheline mosquitoes in southern Ghana. The study was carried out in six villages across three ecological zones of southern Ghana, including: the forest ecological zone (FEZ), the coastal savannah ecological zone (CSEZ) and the forest-transition ecological zone (FTEZ). For every mosquito collected, the indoor resting sites was characterised and microclima...
ABSTRACT The major setback in the exploitation of groundwater in the Central Region of Ghana is poor water qualitydue to high salinity. The source of salinity has not been adequately addressed. The focus of this study was, therefore,to understandthe hydrogeochemical processes occurring in the study area in order to determine the origin of salinity and groundwater residence time. The methodology involved desk study, fieldwork, and laboratory work. The desk study comprised review of literature,...
ABSTRACT Beach sands are known host of different heavy minerals, which occur mostly as placer deposits and are of great importance to the electronics, metallurgy, medical, defense, and automobile industries. Typical examples of such heavy minerals are the rare earth-associated minerals (e.g. monazite, bastnaesite, xenotime and euxenite). Some of these rare earth elements-containing ores are known to occur in association with naturally occurring radioactive uranium (U-238) and thorium (Th-232)...
ABSTRACT Hydrogeochemical and social impact studies were carried out within the Lower Pra Basin where groundwater serves as a source of potable water supply to majority of the communities. The main objective of the study was to investigate the hydrogeochemical processes and the anthropogenic impact that influence groundwater as well as the perception of inhabitants about the impact of their socio-economic activities on the quality of groundwater and subsequently make recommendations towards p...
ABSTRACT Miospores and dinoflagellates recovered from sediments from the ST – 5 and ST – 6 wells, offshore Tano Basin, Western Ghana were studied in order to determine their ages, establish palynostratigraphy and determine environments of deposition. Based on First Appearance Datum (FAD) and (LAD) of marker palynomorphs, three (3) biozones were erected for miospores and dinoflagellates respectively. The characteristic taxa of each of the biozones have been discussed in detail. The three b...
ABSTRACT The use of petroleum products (fossil fuels) has raised a lot of environmental concerns over the past years. This is due to the fact that most of the machines and devices manufactured are engineered to use these conventional fuels which include petrol, diesel and natural gas. However, these fuels substances pollute and deteriorate the quality of the environment. Some of these pollutants include sulphur oxides, nitrogen oxides, particulate matter, and ozone. These gases are called gre...
ABSTRACT Zoonotic diseases are infections acquired from vertebrate animals (wild or domesticated) animals to humans through direct or indirect contact with live animals, their derivatives or contaminated surroundings. The aim of this study is to determine the prevalence of potential bacterial zoonoses in selected trophy hunted species Loxodonta Africana (African Elephant), Syncerus caffer (African Buffalo), Tragelaphus strepsiceros (Kudu), Hippopotamus amphibious (Hippopotamus), Hippotragus ...
ABSTRACT Like terrestrial systems, marine ecosystems are constantly impacted upon by conditions arising from anthropogenically modified abiotic environments, climate change, as well as biotic agents. Marine mussels are widely regarded as ecosystem engineers. The Brown mussel species Perna perna is one such species. Mussels offer a wide range of advantages to intertidal communities through their structure and biomass, as they help increase the spatial heterogeneity in benthic processes, by se...
ABSTRACT There is a connection between urban land use planning and urban sanitation management. The rationale of land use planning is to protect and create attractive urban environments. However, despite the land use planning rationale, there is a sanitation mess in the built environment of the Wa Municipality. This study investigates the implications of land use planning on the provision and management of public sanitation facilities in the Wa Municipality. The study adopted the mixed metho...
ABSTRACT In Rivers State, about three-quarter of its land is covered by water and approximately 70% of all travel between its capital, Port Harcourt and access to most of her Loca l Government Areas is via rivers. Unfortunately, the state and its capital in particular lacks Boat Terminal infrastructure. Apart from this fact and the actual trip was undertaken, other diverse and complex requirements of travellers must be adequate, considered and tackled. The imp importance of public transit sy...
ABSTRACT: Every decision that architects, engineers, builders, and homeowners make about the design and operation of their buildings carries with it an energy cost, and all energy costs in turn have environmental costs. For example, changing the orientation of a window, or the colour of the roof, or adding a sun control will change the amount of electricity it uses for lighting and air conditioning. Passive design; an idea within the growing trend of green buildings, is a creative way to...
ABSTRACT Invasive alien species (IAS) are non-native species that cause, or have the potential to cause, harm to the environment, economies, or human health. The threat to biodiversity due to invasive alien species is considered second to that of habitat loss. The focus of the 2 study was on one of the invasive alien plant Datura innoxia. The study was conducted in the City of Windhoek, the capital of Namibia, situated at 22.56°S, 17.09°E. The aim of the research project was to study the d...
ABSTRACT This study was conducted to investigate the patterns of genetic differentiation of Cape hake (Merluccius capensis) across Southern Africa, using eight nuclear microsatellite markers to understand the seasonal movements of the two previously identified stocks. The aim of the project was to assess the position of the genetic break in two different temporal sampling events: summer months (February – March) and winter months (June – August) and to investigate the level of genetic di...
ABSTRACT This study evaluated the effectiveness of a nutrition education intervention for improved child feeding and caregiving behaviours of rural mothers of poor farm households of Enugu State, Nigeria, using a positive deviant approach. A cross-sectional quantitative and qualitative survey (using an experimental design) was conducted to identify positive deviant mother-child pairs and their uncommon feeding and care practices. A multistage sampling technique was used in the selection...
ABSTRACT The study was undertaken to assess the feeding practices, anthropometric indices, vitamin A, zinc and iron status of under-five orphans living in Federal Capital Territory orphanages, Abuja. A cross sectional descriptive study was conducted using 200 orphans (96 males and 104 females) aged between 0-5 years living in ten orphanages. The subjects were purposively selected for the study and 20% of sub-sample was randomly selected for biochemical analysis and weighed food intake asses...
