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...
Abstract The petrochemical industry is a major contributor of industrial air pollutants which are known to have dire consequences on human health and the environment, neccesitating research into their dispersion and transport. The objective of the study, therefore, is to simulate the dispersion and transport of pollutants emitted during the processing of crude oil by the Tema Oil Renery in the Greater Accra region of Ghana using the California Pu (CALPUFF) modeling system. This thesis couples...
ABSTRACT Fluoride-contamination of groundwater [above the World Health Organization (WHO) recommended limit of 1.5 mg/L] in the Upper East and Northern regions of Ghana is a well-known problem. Fluoride is, however, beneficial to humans if present in drinking water at levels between 0.7 – 1.5 mg/L. Although, there are some efficient methods for defluoridation of drinking water using various adsorbents, the magnitude of the problem has made it imperative to develop economically viable water ...
ABSTRACT Currently, there are over 10,000 telecommunication base stations (BSs) in Ghana. Experts insist the number of BSs is practically inadequate to ensure quality service nationwide. However, in Accra and other urban centers the installation of BSs to expand coverage has met opposition from the public. Accra has a population density of over 15,000 persons per km2 with an annual growth rate of 4.4%; hence, the number of people estimated to live closer to BSs is higher in Accra than in any ...
ABSTRACT The Paleoproterozoic Birimian province of Ghana is made up basically of parallel and equally spaced NE-SW trending greenstone belts (with the exception of one which trends N-S), one of which is the Bole-Nangodi belt which outcrops in the northern parts of Ghana. These belts petrologically consists of metasedimentary and metavolcanic rocks, both of which are intruded by granitoids of various ages. These granitoids can broadly be grouped into four; the Cape Coast, Winneba, Dixcove and ...
ABSTRACT The study explored perspectives of rural food crop farmers in the Lawra District on SWFI communication and uptake. The study was conducted in 4 purposively selected communities. A qualitative approach was adopted and employed exploratory case study design in collecting the data using a convenience sample. Study employed Semi-structured questions and data collection techniques used were in-depth interviews, Focus Group Discussion, participant observations and audio-visual materials....
ABSTRACT The study investigated the impacts of the Pantang and Mallam landfill sites in the Greater Accra Region on the surrounding environment. The Pantang landfill site is an active site that still receives waste of all kinds from various parts of Accra. The Mallam landfill, on the other hand, was decommissioned over a decade ago. Samples of leachate from the two landfill sites and air in the vicinity of the respective sites were taken over a period of three months and analysed. Soil sample...
ABSTRACT Studies were earned out on the effects of variety and processed form of cassava chips on the development of Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) and Araecerus fasciculatus (Degeer) (Coleoptera: Anthribidae). Additionally, changes in the nutrient composition of the chips due to infestation, and the influence of major nutrients on the population parameters of these insects were also studied Statistical analysis of insect preference to the processed chips in a choice...
ABSTRACT The construction of dams on the Volta River and the consequent regulation of the river‘s flow pattern led to the development of a permanent sandbar at the Volta estuary that resulted in many problems for the estuary, with the major one being the disruption of salt water in-flow. Poor salinity conditions of the estuary resulted in, among other things, the development of freshwater plants which served as breeding grounds for some planorbid snails which harboured the parasites that ca...
ABSTRACT Honey is a universal product with a wide usage throughout the life spectrum. It is a substitute for sugar for many people, an energy booster, helps maintain the blood sugar level and research has shown that it has the potential for cancer prevention. The high sugar concentration of honey and its low pH gives honey antimicrobial properties and makes it difficult for microorganisms to grow. However, research has provided evidence of the presence of microbes in honey. The microbes are i...
ABSTRACT The Kpong Headpond was formed in 1982 when the Lower Volta River was dammed at Akuse. The main uses of the water in the Headpond are for hydroelectric power generation, domestic and industrial use and for irrigation. Several activities however, tend to put this body of water at risk of pollution. These include poor waste disposal, poor farming practices and extensive human and animal contact with the water. An eightmonth field study was undertaken to monitor the water quality of the ...
