(University of the Free State, 2014-07)
English: Changes in climatic variability and extremes of weather and climate events have
received increased attention in the last few years. Many studies have been done on
climate trends, especially for precipitation and ...
A generic assessment of waste disposal at Douala City practice, prinicipals and uncertainties
(University of the Free State, 2013-01)
English: One reason why groundwater, so often constitutes the main source of drinking water in many cities and towns around the world, is because it is frequently present in sufficient quantities at the point of demand. ...
Luminescent properties of Y2SiO5:Ce thin films
(University of the Free State, 2010-05)
The luminescent properties of yttrium silicate doped with cerium (Y2SiO5:Ce) phosphor thin films were investigated. A detailed investigation (cathodoluminescence (CL), photoluminescence (PL) and Gaussian peak fits) was ...
Yield stability and mega environment analysis based on the performance of quality protein maize in Sub-Saharan Africa
(University of the Free State, 2013-06-30)
English: Quality protein maize (QPM) which is nutritionally enhanced, has the potential to alleviate malnutrition and related diseases in communities where maize is a dietary staple and often the only source of proteins. ...

(University of the Free State, 2013-01)
The consumption of meat is increasingly linked to various diseases and this has already affected the growth of this sector of the food industry in some countries. Pork is seen as one of the major contributors to this ...
Improvement strategies for yield potential, disease resistance and drought tolerance of Zimbabwean maize inbred lines
(University of the Free State, 2012-06)
English: Breeding for drought and low N tolerant genotypes in Zimbabwe is an important intervention that will see the country curbing the food in-security problem. Both CIMMYT and DR&SS maize germplasm was used in this ...
Investigating the influence of hydrological phase on Baetidae and Simuliidae species composition in a South African non-perennial river: the Seekoei River
(University of the Free State, 2014-01)
All rivers should be monitored to detect changes and disturbances in order to be managed sustainably. Although non-perennial rivers are widespread and common in the semi-arid and arid areas of South Africa they have not ...
Synthesis and characterization of long afterglow phosphors (SrAl2O4:Ce³+, SrAl2O4:Tb³+, CaAlxOy:Tb³+, Y3Al5O12:Eu³+) using solution combustion method
(University of the Free State, 2011-11)
This work consists of several aspects of phosphor materials. Strontium, calcium and yttrium aluminate doped with rare earth (Ce, Tb and Eu) have been synthesized by solution combustion method using urea as a fuel for ...
