ABSTRACT An investigation was carried out to determine the nutritional composition of some selected dominant aquatic plants and their significant effect on chemical and physical characteristics of the water. Four aquatic plants namely Nymphaea lotus, Ipomoea aquatica, Typha ausralis. and Scirpus cubensis were sampled, identified and authenticated at the Ghana Herbarium. The proximate nutritional compositions of the plants were determined using standard procedure outlined in Association of Of...
ABSTRACT Shoreline change analysis provides important information upon which most coastal zone management and intervention policies rely. Such information is however mostly scarce for very large and inaccessible shorelines mostly due to expensive field work. This study investigated the reliability of medium resolution satellite imagery for mapping shoreline positions and for estimating historic rate of change. Both manual and semi-automatic shoreline extraction methods for multi-spectral sat...
Abstract Large-scale production of mine wastes and their secure disposal has been a problem of global concern. In this work, the chemical kinetics of roasting of crude pyrite, a mine waste from Merelani to form sulphur dioxide, a key precursor in the production of sulphuric acid was studied. Conversion of pyrite into sulphur dioxide revealed pseudo first order kinetic with respect of solid reactant in gas-solid system. The activation energy (Ea) value of 15kJ/mol was deduced from Arrhenius e...
ABSTRACT The benefit of breastfeeding to mother and infant is replete in literature. This study investigated perinatal feeding practices in terms of initiation of breastfeeding, use of colostrum and prelacteal feeds among mothers attending Primary Health Care facilities in Isiuzo LGA. Specifically the objectives were to determine: (i) the timing of breastfeeding initiation among women in Isi-uzo Local Government Area. (ii) what women in Isi-uzo Local Government Area use colostrum for. (i...
ABSTRACT Men involvement in family planning would increase its recognition, acceptance and practice by people especially within the rural communities. This is because in rural communities in Nigeria including Enugu, men are still the gate keepers in our families who control power and major decision making. Some of them decide whether their wives will practice family planning or not and the methods to be adopted. This implies the men seem to have the finally say on the number of children the ...
ABSTRACT The purpose of this study was to determine the knowledge and utilization of post abortion care among women of reproductive age (15 – 49 years) in Obanliku Local Government Area of Cross River State, Nigeria. The research utilized a descriptive survey design and a sample size of 350 women of reproductive age (15 – 49), selected from each of the 10 communities in the area. A structured questionnaire was used as instrument to collect data. Information obtained from the question...
ABSTRACT The management of hypertension is tripartite in nature: medication, physical exercise and dietary modification. While medication is curative, physical exercise and dietary modification are both preventive and curative. Dietary and lifestyle changes can improve blood pressure control and decrease the risk of health complications, although treatment with medication is still often necessary in people for whom lifestyle changes are not enough. Physical exercise regimes which are shown t...
Abstract Urban open spaces are an important component of any urban fabric, embracing the activities of different populations. It is one of the most visible elements of the relationship between man and the environment in which he lives, and reflects the general picture of any city. This paper examines the impact of parks and gardens on environmental sustainability in Khartoum city (C.B.D). Urban open spaces, especially parks and gardens, were chosen because they represent the basic elemen...
This research examines four environmental factors influencing women farmers’ adoption of conservation agriculture (CA) in Nakuru County, Kenya. About 30% of environmental problems in the world, and particularly in the study area emanate from poor agricultural practices. CA is currently being promoted as a better practice than the conventional farming methods because CA has been found to result in optimum agricultural production. In addition to resulting in better agricultural yields, CA pro...
Abstract Heavy metals in soil and water were determined at four points along Msimbazi River valley in Dar es Salaam city, which is popular for vegetable farming. Results indicated that the concentration of chromium in water ranged from (1.414±0.922) to 0.01 mg/L. Maximum and minimum lead concentrations of 0.113 and 0.083 mg/L were detected. The concentration of copper was generally low at all sites, ranging from (0.013±0.005) to (0.016±0.005) mg/L. The concentration of lead in water throug...
ABSTRACT In South Sudan like in many other developing countries, one to two thirds of the solid waste generated is not collected. There is a great problem in the household’ management of solid wastes in the rapid growing town of Bor in South Sudan. This study sought to generate information on solid waste handling practices, which could provide appropriate data that can be used to come up with strategies for managing solid waste. The research focussed on 384 respondents in Bor Town in order...
ABSTRACT Climate variability is an emerging global environmental issue of concern, posing a threat especially for pastoral livelihoods of communities in arid and semi-arid lands (ASALs), necessitating an understanding of the emerging climate variability effects on local ecosystems. This study sought to understand the effects of climate variability on pastoralism, focusing on Turkana Central Sub-County in Kenya. The specific objectives of the study were: to analyse rainfall and temperature va...
ABSTRACT Given the subsequent degradation and potential encroachment of mangrove ecosystems, the slow recovery nature of these systems and huge restoration failure efforts (100% mortality after planting in some cases) of mangrove ecosystems, quantification of the role of early colonizing vegetation to mangrove systems recovery is necessary. While sea blight (Suaeda monoica) is common in the degraded sites of Mwache Creek mangrove forest in Kenya and within its growing patches a marked regene...
ABSTRACT The rapidly increasing human population and consequently the human activities carried out especially around wildlife areas such as Mount Elgon trans-boundary ecosystem have increased the pressures on wildlife found in the ecosystem. These pressures occur in the form of habitat loss, poaching and trafficking. Poaching whether commercial or subsistence is a major threat to the viability of wildlife. Not only does it lead to decimation and extinction of some vulnerable species but also...
ABSTRACT Allergic conjunctivitis is a common problem affecting about 20% of the world’s population. In Kenya, it constitutes one fifth of all the total diagnoses made in eye clinics with school teachers in Nakuru North Sub-County in Nakuru County having a prevalence of 51.2%. Untreated allergic conjunctivitis can cause injury to the conjunctiva and the eye lids while some of the drugs used to treat can cause life threatening diseases. Irritants such as the volatile organic compounds which ...
