Galactic propagation of cosmic rays
(North-West University, 2011)The widely used steady-state, rotational symmetric models (2D models) of cosmic ray (CR) propagation, assume smeared-out sources, which do not necessarily result in the same local CR ux as the real local point sources. ... -
Galactosemia : the South African study
(North-West University, 2006)Classic galactosemia and congenital hypothyroidism are both inborn errors of metabolism. The biochemical and molecular detection of both disorders is already defined in scientific literature. Their management is also well ... -
Garlic extract nanoformulation intended for broiler growth performance
(North-West University (South Africa), 2017)Garlic and clove essential oils (EOs) have gained attention from swine and poultry producers, as a replacement to antimicrobial growth promoters (AGPs) because AGPs pose a threat to animal and human health. However, EOs ... -
Gastrointestinal nematodes infecting sheep in Limpopo province : Seasonal prevalence and anthelmintic resistance
(North-West University (South Africa), 2020)The annual cost associated with treatment of parasitic diseases in small ruminants is estimated to tens of billions of US dollars worldwide, from the sales of anthelmintic drugs by pharmaceutical companies, excluding ... -
Gastrointestinal parasites infecting ungulates, felids and avian species at National Zoological Gardens of South Africa
(North-West University (South Africa), Potchefstroom Campus, 2017)Zoological gardens are a form of ex-situ conservation which involves keeping valuable animal species, especially wild animals alive outside their natural environment for educational, research and recreational purposes. ... -
Gauteng farmers’market strategies of Indigenous Leafy Vegetables post COVID-19 outbreak
(North-West University (South Africa), 2023)Indigenous Leafy Vegetables (ILVs) have a high economic potential but there is little information on how to market them. Marketing strategies, how individuals seek information, communication and purchasing of goods have ... -
A gendered approach to climate smart agriculture adoption by smallholder farmers in Malawi and Zambia
(North-West University (South Africa), 2020)The negative impacts of climate change on smallholder agrarian livelihoods in developing countries will be devastating, threatening to negate even the development gains made thus far, while offering opportunities for ... -
A gendered approach to drought coping mechanisms : a case of the Lubombo Region, Swaziland
(North-West University, 2018)In the Lubombo region of Swaziland, one-third (300 000) of Swazis are living through the devastating impacts of drought on both their livelihoods and the environment they depend on. Drought, which has become recurrent, ... -
Gendered approach toward Disaster Risk Reduction: case study of Chobe District, Botswana
(North-West University, 2019)Available research shows an increase in the frequency and intensity of weather and climate-related hazards across the globe. This trend is leading to an increase in the occurrence of disasters and heightened disaster risk, ... -
Generation of a set of SA11 expression plasmids for the development of a T7-RNA polymerase-dependent rotavirus reverse genetic system
(North-West University, 2018)Rotavirus (RV) is a member of the family Reoviridae which contains a segmented double-stranded RNA genome comprised of 11 double-stranded RNA genome segments. Rotavirus is still the leading cause of severe diarrhoea worldwide ... -
A generic framework for promoting the implementation of environmental management systems at local government level in South Africa
(North-West University, 2005)Global environmental problems have been manifesting themselves at such an alarming rate, that the international community decided at the Rio Conference in 1992 that these global problems must inter aha also be attended to ... -
Generic source term determination for tailings storage facilities in the East Rand Basin
(North-West University, Potchefstroom Campus, 2018)The prolonged leaching of gold tailings is a continuous concern in the East Rand Basin typically resulting in acid generation and the release of elements. The leachable constituents from the tailings influences the water ... -

Genetic diversity and nitrogen fixation in underutilized tropical legumes
(North-West University (South Africa), 2019)Legumes in some cases are underutilized and form only a relatively small proportion of human diets. In general they fix atmospheric nitrogen which may provide an economic advantage for smallholder farmers. By appropriate ... -
Genetic diversity of Vetiver clones (Chrysopogon zizanioides and Chrysopogon nigritana) available in South Africa based on sequencing analyses and anatomical structure
(2014)Vetiver grass or Chrysopogon zizanioides (L.) Roberty (1960) is a sterile grass which can regenerate vegetatively from clumps of the rootstock. This, as well as its vigorous and deep root system and flood tolerance makes ... -
Genetic evaluation of growth and reproductive performance of the Afrikaner Cattle Breed
