Avocado seed starch and carboxymethyl cellulose superabsorbent polymer: Synthesis and characterisation.
(2016)
Superabsorbent polymers (SAPs) of crosslinked avocado seed starch and carboxymethyl cellulose were synthesized and their performance as fluid absorption materials was assessed by comparing them with those made from analytical ...
Trends in spatial distribution of alien woody species and primary production on invaded sites in Nyanga National Park, Zimbabwe
(2016-04)
The study sought to establish trends in spatial distribution of the invasive plants, Acacia
mearnsii (black wattle) and Pinus spp (pines) and assess their impact on primary production
in Nyanga National Park, Zimbabwe, ...
Assessment of the impacts of artisanal small scale gold mining on environmental governance within the Mazowe catchment
(2016-06)
This study focused on assessing the impacts of artisanal small-scale gold activities on the environmental governance of the Mazowe catchment. A representative sample of 32 respondents was selected from three sites with the ...
Determination of platinum, palladium, rhodium and gold in ores and concentrates using iridium and ruthenium as co-collectors by fire assay
(2016-04)
Determination of platinum group metals (PGMs) and gold also known as precious metals is always a very difficult task, this is due to their availability in trace amounts in sample types of complex composition. Little research ...
Finite element method with quasi-linearization for solving Bratu's problem
(2016-04)
This work presented here is the solution of one-dimensional Bratu’s problem. The major aim of
this research is to master the techniques used to solve the Bratu problem. The nonlinear Bratu’s
problem is first linearised ...
A Note on the Discrete Spectrum of Gaussian Wells (I): The Ground State Energy in One Dimension
(Hindawi Publishing Corporation, 2016-02-07)
The ground state energy 𝐸 0(𝜆) of 𝐻 𝜆 = − 𝑑 2 /𝑑𝑥 2 − 𝜆 𝑒 −𝑥2 is computed for small values of 𝜆 by means of an approximation of an integral operator in momentum space. Such an approximation leads to a transcendental ...
Modeling Habitat Selection for Southern White Rhino (Ceratotherium Simum Simum) in Matopos National Park
(University of Zimbabwe, 2016-06)
In this study we modeled wet and dry season habitat selection of the Southern white rhinoceros (Ceratotherium Simum Simum) in Matopos National Park. We tested whether wet and dry season habitat selection was influenced by ...
Possibilities of water pollution in Cheche and Mtilikwe rivers by stillage from Triangle
(2016-04)
The main aim of this project was to perform an investigation on the possible impact of
Triangle limited stillage on Cheche and Mtilikwe river water quality. This was done by
measuring physico- chemical parameters and ...
Preliminary studies on the winter season abundance and fitness of tephritid fruit flies in the Harare area, Zimbabwe
(2016-04)
Fruit flies (Diptera: Tephritidae) are among the major constraints in commercial fruit
production in many developing African countries. Due to their economic importance,
knowledge of the tephritid fruit fly spectrum ...
Accuracy assessment of MODIS fire products in African Savanna woodlands
(University of Zimbabwe, 2016-06)
Fire poses a continuous threat to forest ecosystems and can dramatically reduce valuable timber species in forest woodland areas. The occurrence of fire in Baikiaea plurijuga woodlands warrants the need of an active and ...
