Sub-Saharan Africa is large and diverse with regions of food insecurity and high vulnerability to climate change. This project quantifies carbon stocks and fluxes in the humid forest zone of Ghana, as a part of an assessment in West Africa. The General Ensemble biogeochemical Modeling System (GEMS) was used to simulate the responses of natural and managed systems to projected scenarios of changes in climate, land use and cover, and nitrogen fertilization in the Assin district of Ghana. Model...

This study examined the relationships among self-efficacy beliefs, intrinsic and extrinsic motivation, and academic adjustment among 111 African American women in college. Results revealed that self-efficacy beliefs predicted Motivation to Know, Externally Regulated motivation, Identified motivation, and academic adjustment. Furthermore, Motivation to Know partially mediated the relationship between self-efficacy beliefs and academic adjustment. Contrary to prediction, extrinsic motivation...

The present study aimed to predict Tanzanian medical students’ Voluntary Counseling and Testing (VCT) participation intention using the Health Belief Model (HBM) as a theoretical framework. Further, differences between respondents who had previously participated in VCT and respondents who had not were assessed. Cross-sectional data were gathered from 186 Tanzanian medical students using a self-administered questionnaire. Almost half of the respondents (43.3%) reported having been tested for...

This paper describes the determination of the levels of lead (Pb), cadmium (Cd), zinc (Zn), calcium (Ca) and iron (Fe) in the toenails and fingernails of children under the age of six years in urban and rural areas in Kenya by atomic absorption spectrophotometer. Lead levels in urban areas ranged from 8.0-49.0 μg/g in fingernails and 7.0-62.0 μg/g in toenails as compared to those in rural areas (5.0-36.5 μg/g and 5.5-31.5 μg/g, respectively). A similar trend was observed for Cd where...

The unstable and turbulent environment in which higher education institutions all over the world currently have to operate poses many management and marketing challenges to such institutions. As non-profit organisations, the ability of higher education institutions to survive and grow would be enhanced by up-to-date knowledge and information regarding the higher education environment, and more specifically by having marketing and communication strategies that might influence students making...

This study determined, in comparison with guideline limits, the levels of Polycyclic Aromatic Hydrocarbons (PAH) in the soils at Eleme (highly industrialized) and Ahoada East (less industrialized) communities in the Niger Delta Area. Sixteen grab soil samples with 8 samples each from different locations in each community were collected at depth 0 - 15 cm using an auger. About 500 g of soil from each location were processed and analyzed for pH, moisture content, organic matter, phenol, and...

Twenty (20) Traditional Health Practitioners (THPs) from Khayelitsha Township in Cape Town were being trained in tuberculosis (TB), Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS). Khayelitsha is among the biggest townships in the City of Cape Town Metro pole. The city is about 30 km south of Cape Town. Based on scientific research articles Khayelitsha has a high prevalence of TB cases. The THPs were randomly selected from different sections of the township...

This study determined the susceptibility pattern and multiple antibiotic resistance (MAR) index of 92 Pseudomonas aeruginosa strains from clinical samples comprising mainly urine (51.1%) and wounds (41.3%) obtained from the surgical units of Ahmadu Bello University Teaching Hospital, Zaria, Nigeria; over a 24-month period. The strains were susceptible to imipenem (94.6%), ciprofloxacin (90.2%), amikacin (89.1%) and ceftazidime (78.3%) but resistant to ofloxacin (82.6%), perfloxacin (58.7%)...

The computer has witnessed a wide range of applications in virtually all human endeavours.
