ABSTRACT Elite cowpea varieties IT84E-124 and Vita 7 of the International Institute for Tropical Agriculture, Ibadan, were exposed to varying doses of chemical and physical mutagens. Optimum doses of 10mm EMS for 6 hours and 0.1mM and 1.0mm NaN, for 2 hours, determined from seedling growth tests, and 100R and 200R gamma radiation were applied to seed samples of cach genotype. A total of 2000 seeds from each cultivar/treatment were planted. The suitability and efficacy of the treatment regimes...
ABSTRACT The public sector is witnessing a digital revolution and are being challenged by many obstacles as correct electronic platforms are provided for the improvement of collaborative activities, sharing of information and knowledge, regardless of time, space or location. In this study the focus was on three main subject matters: decision-making, tools for collaboration, and challenges that may arise when using these tools for collaborative activities. The empirical part of the thesis empl...
SUMMARY Antisera were produced against the most prevalent Campylobacter strains 'LA 4', LA 12', 'LA 36', 'LA 53, LA 78 and 'LA 1214' isolated and identified in Lagos, Nigeria. A total of two hundred other Campylobacter strains were screened using the six antisera produced to determine their serogrouping, Eight (4.08) of the strains reacted positively with antiserum raised against strain LA 4", seventy-seven (38,58) with antiserum raised against strain 'LA 36"; eleven (5,5%) reacted with the a...
ABSTRACT This document entails full details of research given in phases of the development of the Adverse behaviour and protest prediction system for Zimbabwe Ezekiel Guti University (ZEGU). It is a sentiment analysis system designed to read sentiments in text posted by students and members of the university community at large in order to aid the institution’s administration in predicting possibility of protests at the university. It was seen necessary to develop this system due to several ...
ABSTRACT Urinary Tract Infections (UTIs) are a serious problem globally and are some of the most common diseases encountered in medical practice today. Despite the widespread availability of antibiotics, UTIs remain a problem because of antimicrobial resistance. Antimicrobial susceptibility testing therefore provides information that allows physicians to select the most appropriate antibiotics for UTIs. This study was carried out to: (i) determine the prevalence of UTIs among patients present...
Abstract The purpose of this study is to unpack computer aided teaching. It focuses on an exploration into the methods of using a computer as a teaching tool for ordinary level students in Shurugwi District Urban Cluster located in the Midlands Province. A multiple case study approach was used to gather relevant data required for the study. Three School Heads, three computer science teachers and six pupils from form three and four purposively participated in the study. The research attempted ...
ABSTRACT Steady-state problems in Engineering and Applied Science can be modelled in a way that requires the solution of differential or integro-different in equations, involving the Laplacian equation. Numerical procedures instead of variation and analytical tecniques) are often applied through the finite difference approximations among other techniques. In this research, the finite-difference expressions for two two, three and n-dimensional Laplacian operator based on linear, quadratic and ...
ABSTRACT This thesis reports on a statistical analysis on risk factors associated with under-five mortality in Namibia. Secondary data were obtained from the 2013 Namibia Demographic and Health Survey data. Children survival was measured by age at death and the event variable was whether the children were still alive or dead after the first five (years) of their lives. Variables included were maternal education, mother’s marital status, the age of the mother at first birth, preceding birth ...
ABSTRACT The need for utilizing renewable resources to meet the future demand for fuel and other value added products has increased the attention on lignocellulose, the most abundant and renewable resource in the world. Lignocellulose is degraded by lignocellulolytic enzymes produced by fungi and bacteria. Mutagenic agents can be used to achieve improvement of these strains. However, there has been a challenge in improving and optimizing fermentation process which in most cases has been carr...
ABSTRACT Four thousand, three hundred and ninety five throat, 4,395 nasal and 58 skin lesion swab-specimens were examined bacteriologically out of which 401 (9.12%) were positive for beta-haemolytic streptococel (GHS) and 11 (0.25%) for non- haenolytic streptococci (NS). On the basis of Lancefield group polysaccharide antigens, the 1solates were classified into groups A, C, D, G and non-groupable BHS strains. On the basis of bacitracin sensitivity and blochemical analysis, these groups and un...
ABSTRACT The main objective of mobile operators is to enable mobile users to stay connected while roaming across heterogeneous networks. As cellular networks evolve from the third generation Universal Mobile Telecommunication System (UMTS) to the Long Term Evolution (LTE), a new Evolved Packet Core (EPC) will support heterogeneous radio access networks on the same platform. UMTS provides voice services in the circuit switched domain; while LTE operates in the packet switched domain. Cellular ...
ABSTRACT Aphids (Myzus persicae nicotianae) cause damage by sucking sap from the plants leading to distortion and wilting of the foliage, and eventually reducing economic yields. In order to minimise losses to viral diseases, it is important to use insecticides in association with fungi to control insect pests in an environmental and ecological friendly way without contaminating the environment. A study was carried out from October, 2013 at Kutsaga Research Station in the laboratory to evalua...
ABSTRACT Aeronautical Publications and Flight Permits Processing System is a web-based computer system that automates all the processes that are involved in issuing flight permits, as well as recording and management of publications. Its major thrust is to provide a secure platform to issue flight permits for over flight and landing, and to conduct Airport surveillances online. The system deals with the creation and management of applicants or operators’ accounts since some Aircraft operato...
A BSTRACT “Technological process is like an axe in the hands of a pathological criminal.” (Einstein 2015).The non-existent mobile payment security governance framework for Mobile Network Operators (MNOs) is directly or otherwise, causing constant challenges to mobile payment systems (MPS) subscribers who include systems and service providers, and operators and general clients in Zimbabwe. Consequently, there is perceived yet undetermined lack of clientele trust, confidence and convenience...
ABSTRACT The purpose of this research was to provide a working and lasting solution to the challenges being faced by the Zimbabwe Republic Police (ZRP) at Criminal Investigations Department (CID), Central Criminal Bureau (CCB) in particular. To achieve the best results for this project, a number of methodologies, information gathering techniques and development tools were carefully used.
