Land use/ land cover changes and stakeholders: Investigating sustainable natural resources management options for an a1 farm a case study of Essexdale farm in Marondera district, Zimbabwe
(2016-04)The tracking of the land use/land cover changes that took place in Essexdale Farm (a communal resettlement area in Marondera District of Zimbabwe) from the period 1985 to 2012 was conducted using the two methods: the ... -
The limnological status of the Gwebi river, Zimbabwe
(2016-10)The study aimed at assessing the limnological status of Gwebi River. Sampling was carried out from March to August 2015 on eight sites along Gwebi River. Five classes of land use/ land cover namely; woodland, grassland, ... -
Limnological study of Malilangwe reservoir in the South-eastern lowveld of Zimbabwe
(2014-07-17)The study provides a nine month record of the limnological investigation of the Malilangwe reservoir between February to October 2011. Malilangwe reservoir is large (211 ha), and shallow (mean depth 4.54) reservoir situated ... -
The Limnology and Ecology of Two Small Man-Made Reservoirs in Zimbabwe.
(2012-08-30)This study investigated the limnology of two small dams (< 5ha) built in series on Munwahuku river. Very little is known about the ecology of such small water bodies and the hydrological regime of these dams is that they ... -
Low-frequency asymmetric vibrations of a tn shell with sign-changing curvature.
(2012-09-03)Most problems in Applied Mathematics involving difficulties such as nonlinear governing equations and boundary conditions, variable coefficients and complex boundary shapes preclude exact solutions. Consequently exact ... -
The Macroinvertebrate Communities Of Two Upland Streams In Eastern Zimbabwe With Reference To The Impact Of Forestry
(2012-08-28)Benthic macroinvertebrates and physico-chemical parameters of the water were examined from two fast flowing streams, the Nyahode River which drains a pine monoculture catchment and the Haruni River which drains an undisturbed ... -
Magnetic nanopore composite beads for simultaneous removal of organic and inorganic pollutants in highly acidic water
(2016-10)A novel magnetic nanocomposite bead was synthesised for the simultaneous removal of cationic, anionic and organic pollutants removal in highly acidic water. Copper, chromium (III), phosphate and toluene were used as ... -
Maize Yield Forcasting in Malawi Using Satellite Data and a Soil Water Balance Modelling Aproach.
(2012-09-07)The potential of using Normalized Difference Vegetation Index (NDVI) and the AgroMetShell (AMS) to forecast and estimate maize yield at Rural Development Project (RDP) level in Malawi was investigated. NDVI is derived from ... -
Maize yield prediction using seasonal weather forecasts and a crop growth simulation model.
(2012-09-13)Maize production in marginal tropical regions is at great risk from rainfall variability. Farmers would benefit from the ability to forecast production likelihood. In this study we sought to develop a simple maize ... -
Malaria Vector Status and Insecticide Susceptibility Studies in Zimbabwe
(2012-08-29)The major problem that has evolved from malaria control progammes that utilize insecticides for vector control is the development of insecticide resistance. In Zimbabwe, despite decades of pesticide usage there is limited ... -
Management of Eutrophication in Small Dams with Both Urban and Rural Catchments in Zimbabwe: a Case Study of Rufaro Dam, Marondera, Zimbabwe.
(2012-08-28)An investigation was carried out on the limnological status and the nutrient loadings of Rufaro Dam, in Marondera. The limnological parameters of the water in the dam and the inflows that were measured were conductivity, ... -
MANETS/VANETS in AutomobileSystems: A Simulative Study into how Mobile Ad-hoc Networks can be used in Traffic Control Systems
(2012-08-29)This thesis describes the modeling and implementation of an advanced traffic signal control system within a simulation environment, thus creating a laboratory for the evaluation of advanced traffic control strategies ... -
Markers of inflammation, morbidity and mechanisms mediating resistance against Schistosoma haematobium infection in preschool age ahildren (Children aged five years and below).
(University of Zimbabwe, 2021-06-09)Schistosomiasis is caused by a blood fluke worm of the genus Schistosoma. Adult worms can live for decades in the human host releasing ova causing inflammatory and obstructive disease in the urinary system. The preschool-age ... -
A Mathematical Model Of Combined Pre-Exposure, Post-Exposure Vaccines And Treatment Of Tuberculosis
(2012-09-03)Due to high prevalence of tuberculosis (TB) in developing countries where HIV prevalence is also high, developing effective TB vaccines that will prevent infection and reactivation of latent infection is a high priority. ... -

(2012-08-30)Mining activity and mine wastes at Athens mine; Mvuma, Zimbabwe, have been generated since the 15th century accelerated significantly during the 20th century. The mine wastes constitute a potential source of contamination ... -
Minimal Variance Hedging In A Discrete Time Market Driven By Markov Process
(2012-09-03)Techniques in stochastic analysis are presented in a continuous time framework.We then review methods in quadratic hedging approaches with focus on minimal variance hedging in a discrete time framework. We also consider ... -
Modeling dependence across stock markets using copulas.
(2012-08-28)An important issue in multivariate statistical modeling is the choice of the appropriate dependence measure. Correlation has many pitfalls as it is associated with the elliptical distributions assumption of normality which ... -
