(2020)The Nguni is indigenous multi-purpose cattle breed that plays an important role in both commercial and communal farming systems in South Africa (SA). Unfortunately, the breed is currently under threat of diminishing ...
-
(2020)Stillbirth is a trait of high economic importance in dairy cattle and is increasingly being included in dairy cattle breeding objectives worldwide. In South Africa, however, there is limited information on stillbirth ...
-
(2021)Temperature extremes have a crucial impact on agricultural, economic, health and energy sectors due to the occurrence of climate extreme events such as heat waves and cold waves. Limpopo province is among the hottest ...
-
(2020)Avocado fruit ‘Hass’ harvested during early-season and exposed to temperature at 5.5°C for 28 d are susceptible to chilling injury (CI); and therefore, develop poor skin colour during ripening. In ‘Hass’ avocado fruit, ...
-
(2020)Peritoneal Dialysis (PD) is a process of replacing kidney function which cleans waste from the blood and remove extra fluid from the body. In most cases, the process of PD is slowed down by a peritoneal membrane infection ...
-
(2020)The aim of the study was to assess the extent to which biological indicators and biomarkers can be used to monitor the pollution status of the Sand and Blood Rivers. Physico-chemical parameters were assessed as a primary ...
-
(2020)In this study we present the numerical solution o fboundary value problems for the reaction-diffusion equations in 1-d and 2-d that model phenomena such as kinetics and population dynamics.These differential equations ...
-
(2020)The aim of this study was to investigate the role of Information Communication Technology tools in facilitating development within Community-Based Farming Projects (CBFPs) served by Mankweng Service Centre (MSC). The ...

Lithium manganese oxide (LiMn2O4) spinel surfaces and their interaction with the electrolyte content (2020)This dissertation presents the results of the ab-initio based computational studies of spinel lithium manganese oxide (LiMn2O4) bulk, surfaces, and the adsorption of an organic electrolyte, ethylene carbonate. The ...
-
(2020)Language modelling (LM) work for under-resourced languages that does not consider most linguistic information inherent in a language produces language models that in adequately represent the language, thereby leading to ...
-
(2020)In nature, saccharification is done by a variety of microorganisms, secreting a variety of cellulase in addition to other proteins. Co-culturing enables the production of more efficient enzyme preparations that would mimic ...
-
(2019)Functional Itˆo calculus is based on an extension of the classical Itˆo calculus to functionals depending on the entire past evolution of the underlying paths and not only on its current value. The calculus builds on ...
-
(2020)South African dairy cattle industry is characterized by a dual production system, comprising of a high input commercial production system and low input smallholder and emerging dairy herds. Performance data from both systems ...
-
(2020)The main purpose of modelling rare events such as heavy rainfall, heat waves, wind speed, interest rate and many other rare events is to try and mitigate the risk that might arise from these events. Heavy rainfall and ...
-
(2020)Bush encroachment is a major problem in arid and semi-arid savannas characterized by a grass layer interspersed with a shrub stratum. Land cover change as a result of rapid proliferation of woody species in previously open ...
-
(2020)Production of bioethanol from lignocellulosic biomass has gained significant attention worldwide as an alternative fuel source for the transportation sector without affecting food supply. Efficient conversion of pentose ...
-
(2020)Spectrum scarcity is one of the major problems affecting the advancement of wireless technology. The world is now entering into a new era called the “Fourth Industrial Revolution” and technologies like the Internet of ...
-
(2020)Surface properties of pyrite (FeS2), chalcopyrite (CuFeS2), galena (PbS) and sphalerite (ZnS) most thermodynamically stable surfaces have been studied using first priniciples density functional theory. The most stable ...
-
(2020)The flow of electrically conducting fluids in the presence of a magnetic field has wide applications in science, engineering and technology. Examples of the applications include industrial processes such as the cooling ...
