Abstract The prevalence of diverse factors affecting maintenance management determines the impact of such factors on the maintenance of prison facilities. This study investigates factors that affect the maintenance management of prison facilities in South-West, Nigeria. Questionnaires were used to collect data from the prison staff in the maintenance unit of all prisons situated in South-west, Nigeria. The statistical tools employed for the study were percentage, mean scores, kendall's coeff...
ABSTRACT BACKGROUND: Escherichia coli (E. coli) is a bacterium that can asymptomatically colonize a woman’s vagina and up to 31% of pregnant women are colonized worldwide. Furthermore, vaginal colonization with E. coli is associated with adverse pregnancy outcomes, such as preterm birth and stillbirth. It is also associated with neonatal sepsis or meningitis when transmitted to the foetus through amniotic fluid or to the neonate during delivery. To date in Namibia data on the colonization a...
ABSTRACT Respiratory infections represent a major global health problem, and occurrences of respiratory diseases have been increasing in Southern Africa countries including Namibia due to anthropogenic activities. This study was conducted in Tsumeb, a municipal township located in the Northern part of Namibia. It aimed at determining the prevalence of respiratory ailments among the residents, identify risk factors associated with the prevalence and recommend appropriate measures to prevent ex...

Abstract This study assesses the sustainability of locally initiated community gardens as an adaptation strategy against climate change-induced food insecurity in Chikato ward 7 of Shurugwi district. Triangulation approach was employed in this study in which both qualitative and quantitative methods were used to collect data. Qualitative techniques included open-ended questionnaires, interviews, observations, focus group discussions and secondary data. Quantitative techniques comprised of clo...
ABSTRACT The fast food industry has an important role in meeting the ever increasing food demands of the urban dwellers in developing countries. The catering industry in Zimbabwe is growing exponentially as evidenced by the opening of new takeaways, restaurants, lodges and hotels. It is estimated that 15 percent of the total population in Zimbabwe buy food from various food outlets on a daily basis. The aim of the study was to make an inference on the food handling practices currently prevale...

Abstract Leaching and speciation of heavy metals in stabilized gold mine tailings were investigated by using leaching tests and leaching model (Visual MINTEQ 3.1®) respectively. Results indicate that the Stabilized/Solidified (S/S) tailings has high acid neutralizing capacity, which is dependent on binder content used. The dissolution of alkaline metals and oxyanions (such as SO4 2-, HCO3 2-) raises both the pH and electric conductivity of the leachant and, in-turn, affects leaching of the ...
Abstract This paper presents results of the investigation of Chromium III removal from tannery wastewater using groundnut shells under laboratory scale batch experiments. The effects of pH, contact time, particle size and dosage of the adsorbent on the adsorption of Cr (III) were studied. Determination of Chromium ion concentration in the wastewater was done using Atomic Absorption Spectrophotometer (AAS). Results show that removal mechanism is dominantly adsorption, which is dependent of th...
Abstract The impacts of teenage pregnancy, HIV/AIDS and other sexually transmitted infections among the youth such as dropout from school, long term effects and death is felt by most people worldwide. As a result of this, teenagers are in need of information regarding sexuality and safer sex to enable them to protect themselves against HIV/AIDS and other sexually transmitted infections and to prevent unintended pregnancies. The purpose of this study was to explore and describe knowledge, atti...
ABSTRACT The objective of this study is to analyse the Physico-chemical and bacteriological parameters, evaluate the performance of domestic sewage ponds at the Accra sewage treatment plant at Legon. The aim is to assess the suitability of the final effluent for irrigation and the quality of sludge for agriculture use. A total of 36 wastewater samples and forty-eighty (48) sludge samples were therefore taken for six (6) consecutive months from the sedimentation tank (inlet) and maturation po...
ABSTRACT A significant proportion of people in semi-arid regions depend on climate variables and agroecosystem services to sustain their livelihoods. These livelihoods are threatened by the deterioration of agroecosystem services and climate variability. Recently, many communities exhibit low levels of adaptive capacity due to maladaptation and the lack of understanding of the patterns of vulnerabilities. This study examined the scope and nature of vulnerability and adaptation strategies of s...
ABSTRACT Forests are considered to be a strategic resource for national development and have great importance on a nation’s environment. Despite increasing concern over the loss of tropical forests and the significant local and international efforts to find solutions to the problems, the rate of deforestation in the tropics continues to increase. Though Ghana’s timber export is the fourth largest industry after gold, tourism and cocoa, her primary rain forest has reduced drastically over...
ABSTRACT Coastal zones are considered as one of the productive zones of the world. With diverse ecosystems, they provide humankind with immense ecological services. However, coastal aquatic ecosystems have been increasingly threatened as a result of population growth and increased rate of economic development. To address this issue, there is the need to reshape attitude and practices in the current rate of development, for the mutual benefit of aquatic ecosystems and human societies. This st...
SUMMARY We present a joint analysis of newly acquired gravity and teleseismic data in the North Tanzanian Divergence, where the lithospheric break-up is at its earliest stage. The impact of a mantle upwelling in more mature branches of the East African Rift has been extensively studied at a lithospheric scale. However, few studies have been completed that relate the deep-seated mantle anomaly detected in broad regional seismic tomography with the surface deformation observed in the thick Arc...
