Remote sensing patterns of net primary productivity in the Great Limpopo Transfrontier Conservation Area (GLTFCA) in relation to land use and land tenure
(2014-10-07)
Net Primary Productivity (NPP) is an important indicator of ecosystem health and its
estimation and understanding of factors determining its spatial and temporal variations is
critical. Previous studies have mainly ...
On Groups which are Products of Weakly Totally Permutable Subgroups
(2014-04-24)
This work is a contribution to the theory of products of finite groups. A group G = AB is a
weakly totally permutable product of subgroups A and B if every subgroup, U of A such that
U ≤ A ∩ B or A ∩ B ≤ U, permutes with ...
Molecular Typing of Salmonella Serotypes Isolated from Wildlife, Domesticated Animal Species and Humans in Zimbabwe
(2014-04-10)
Salmonella enterica serovar enteritidis (S. enteritidis) is one of the major causative agents of diarrhoea in humans and is associated with the ingestion of contaminated animal products such as meat, poultry and poultry ...
Nutritional content, phenolic compounds composition and antioxidant activities of selected indigenous vegetables of Zimbabwe
(2014-07-21)
Foods of plant origin may contain many phytochemical compounds such as phenolic
compounds in addition to commonly identified nutrients. Interest in phenolic compounds
has greatly increased recently because these ...
Remote sensing of waterhole distribution and its impact on wildlife and livestock interactions across a gradient of land use in a Southern African savanna
(2014-10-07)
Arid and semi-arid ecosystems are water limited ecosystems. Thus, understanding the spatial and
temporal dynamics in water availability is critical. In this study, we tested whether and to what
extent we can use remotely ...
The effects of Trojan Mine waste rock dump and Madziwa tailings dump on the environment
(2014-06-26)
The Mazowe Valley contains several of Zimbabwe‘s largest current and closed mining operations. It is densely populated and is also a major agricultural area. The urban and rural areas of Bindura, Goromonzi, Shamva, Marondera, ...
Optimal stochastic control and risk minimisation in Insurance
(2014-06-17)
The thesis examines a generalised problem of optimal control of a firm through
reinsurance, dividend policy and convex risk minimisation in the presence of
market friction. The major mathematical tool applied is the ...
Spatial distribution of elephants (LOXODONTA AFRICANA) in Hwange Mining Concession area
(2014-10-07)
In this study we tested whether and how environmental factors such as distance from water
points inside mine dumps, distance from water points outside mine dumps, distance away from
settlements, distance away from ...
A universal electronic payment model in Zimbabwe integrating with Small and Medium Enterprises and working with mobile databases
(2014-07-17)
Electronic payment systems are proliferating in banking, retail in government and everywhere
money needs to be exchanged. Electronic payment systems are the everyday technology under
use, they are the relevant systems ...
Modelling of the response of sable antelope (Hippotragus niger niger) to trophy hunting: A GIS and remote sensing approach
(2014-10-07)
The main objective of this study was to test the impact of hunting on sable (Hippotragus
niger niger) habitat selection using a combination of satellite remotely sensed data and GIS
based spatial analysis. Firstly, we ...
