ABSTRACT The study investigated the level of Implementation of Information Technology Policy and Students’ Computer Competency in selected Government secondary schools in Gaya Zone-Kano State, Nigeria. The study was guided by the three objectives: to determine the level of Implementation of IT Policy, to assess students’ computer competency and to establish the relationship between the implementation of IT Policy and Students’ Computer Competency. This study adopted mixed approaches, co...
Abstract Hydrogenated Amorphous silicon (a:Si:H) has low amounts of defects making it attractive for photovoltaic applications. To improve power conversion efficiency (PCE) of a:Si:H solar cells, this study investigated the effect of introducing FTO/TiO2 multilayer thin films into its structure to serve as antireflection coating. The multilayer thin films were characterized and optimized by optical simulations using a computer program, GLSIM (glazing simulator). The program was written in FO...
ABS TRACT A Web Browser is a computer application used to access information on the World Wide Web. The browser‟s parsing capability has advanced over years since its inception. The advancements have consequently increased demand for memory as manifested by computer crawl. Contemporary browsers are anchored on reference architecture that lacks memory control mechanism that can limit maximum memory a browser can use thus posing a challenge in multiprogramming environments with less memory th...
Abstract: The savanna elephant is a flagship species for conservation in Maputaland, a biologically diverse centre of endemism. At present Maputaland’s elephants are fragmented into two sub-populations, those confined to the Tembe Elephant Park (TEP) and those roaming across the Maputo Elephant Reserve (MER) and along the Futi Corridor. Fragmentation may have affected the sub-populations by skewing age and sex ratios, decreasing survival, isolating the sub-populations, and restricting land...
ABSTRACT Dye-Sensitized Solar Cells (DSSCs) are promising third-generation photovoltaic devices that offer the conversion of light energy into electricity at a lower cost. At the heart of this device is a sensitizer (dye) adsorbed on TiO2-photoanode, which is responsible for the harvesting of visible light energy. However, the currently used sensitizers offer little improvement to the overall cell efficiency and this constitutes the main challenge to this technology. This work reports a comb...
Land evaluation, characterization and classification of soil for the proposed oil palm plantation in Ekpri Ibami, Akamkpa Local Government Area, Nigeria was conducted on 50 ha of land using a combination of both conventional and digital survey methods. The objective of the research was to characterize, classify and evaluate the land for the proposed oil palm production. Three soil mapping units were identified (EKP I, EKP II and EKP III) and representative profile pits were du...
ABSTRACT The hydrogeological conditions of University of Ghana, Legon Campus was assessed using geophysical and numerical techniques. Data from borehole lithological logs and electrical resistivity survey was used to conceptualize the hydrogeological system of the terrain whiles using MODFLOW to generate groundwater flow simulation models under steady state conditions. The objective of the study was to conceptualize the hydrostratigraphy through geophysical techniques, develop a groundwater f...
ABSTRACT The main source of natural internal irradiation of man is radon and its decay products. In this study, the radon concentration levels in selected homes in Aburi of the Akuapim North Municipal Assembly in Eastern Region, Ghana were estimated using time-integrated passive radon detector; LR-115 Type II solid state nuclear track detector (SSNTD) technique. The primary objective of the study was to measure radon levels in 30 selected homes in the Aburi municipality and determine the unc...
ABSTRACT Mosquitoes are the primary vectors of arboviral infections. As there are no vaccines or effective therapeutic treatments for these diseases, vector control is an important approach for curbing their circulation or transmission. These vectors spend the first three of their four life stages in aquatic habitats where fitness and efficiency of adult mosquitoes to transmit arboviral infections is greatly influenced. Understanding ecology of mosquitoes in their aquatic habitats is therefo...
H. pylori is a microaerophilic organism and a gram negative bacterium which is found in the alimentary canal. It causes chronic gastritis and gastric ulcers. It is also linked to the development of duodenal ulcers and stomach cancer, conditions that were not previously believed to have a microbial cause. The persons infected with H. pylori usually have a 10 to 20% danger of developing peptic ulcersand a 1 to 2% likelihood of acquiring stomach cancerin lifetime. Nearly 15% of infected persons ...

ABSTRACT Although curriculum is the key to learning in every learning institution, there have been complaints about poor performance in certain schools, subjects and regions every year resulting from ineffective curriculum development and implementation. The purpose of the study was to find out the impact of CDF on secondary school Curriculum implementation in Nyahururu District.The objectives of the study were to find out the; extent to which CDF has addressed the textbooks shortages, infras...
ABSTRACT The past decade has seen a huge increase in the implementation and use of Electronic document and records management systems (EDRMS) in many public spheres. From the available literature, it seems that Government organisations and companies have been lagging behind in this regard. This Project rep011 investigates GESES Records Management System. This is being used by GESES Uganda Limited where traditional systems were found to be completely manual and subject to numerous problems li...
ABSTRACT Undergraduate medical education in Nigeria like other areas of human learning is under pressure due to students‟ over-population, unmanageable classroom and laboratory teachings coupled with the need to expose students to clinical, theatre and surgical experiences. Thus, this study was driven by the need to undertake a baseline investigation that will explore and evaluate strength and weaknesses in utilization and impact of Computer-Mediated Learning on medical undergraduate studen...
ABSTRACT This study investigated the effect of Computer Simulation and concept model on selected Senior High School conceptual understanding of cell cycle. The target population was SHS biology students in the Central Region of Ghana. The accessible population was second year elective biology students in Mfantseman Municipality in the Central Region. The study employed quasi-experimental design and 70 second year elective biology students were purposively selected to participate in the stud...
