Characterisation of signalling cascade by HBV genotypes in Hepatocellular Carcinoma progression
(2018)
Background
Hepatitis B virus (HBV) genotypes have different clinical outcomes in the progression of hepatocellular carcinoma. The HBV encodes two regulatory proteins, the LHBs and the HBx.
Methods
We analysed the impact ...
Water holes typology as a function of human and ungulate Activities in Hwange National Park, Zimbabwe
(University of Zimbabwe, 2018)
Small aquatic ecosystems in semi-arid environments are characterised by strong seasonal water level fluctuations. Artificial pumping of ground water to maintain water resources throughout the dry season may affect the ...
Deep learning for improved plant classification
(2018)
Plants are crucial in the ecosystem: they enable life by providing oxygen, they have medicinal properties, among many other uses, and hence their classification is vital. Automating plant identification has remained a ...
Effects of nitrogen fertilization and precipitation decline on tree-grass interactions in Southern African Savannas
(University of Zimbabwe, 2018-10)
Savannas are heterogeneous ecosystems comprising of a co-dominance of herbaceous and woody species and these ecosystems support millions of people as well as diverse mammalia species. Recent research has established that ...
Purification of water using surface engineered zeolites
(2018)
Coal fly ash obtained from Coca Cola Company in Harare was utilised in synthesis of zeolites by hydrothermal method using 3M NaOH. The Ze-ZnO nanoflakes and Ze-ZnO nanorods were successfully synthesised using a combination ...
Synthesis of a novel visible light responsive γ-Fe2O3/SiO2 /C-TiO2 magnetic nanocomposite for water treatment
(2018)
Recovery of TiO2 from a solution after photocatalysis is a matter of concern since it allows for reusability and better purification. Maghemite nanoparticles coated with silica and carbon doped titanium dioxide were ...
