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 ... -
Game farms as sustainable ecotourism attractions
(North-West University, 2004)It is clear that tourism, especially ecotourism, in South Africa is growing at a rapid pace. Each year more and more tourists travel to South Africa with their main aim to visit places that are based on the natural ... -
A game theoretic analysis of South Africa's cellular information and communication technology sector
(North-West University (South Africa), 2001)A game theoretic approach of South Africa's cellular information and communication sector The "new economy" has become a reality for South Africa. An economy driven by factors such as globalisation and technology. If ... -
A game theoretic approach to improve energy efficiency of wireless sensor nodes
(2015)Wireless sensor networks (WSNs) are becoming increasingly pervasive in a number of applications. Due to the nature of WSNs, one of their biggest constraints is limited node energy. As WSNs grow in popularity, the prevalent ... -
GARCH models based on Brownian Inverse Gaussian innovation processes
(North-West University, 2006)In classic GARCH models for financial returns the innovations are usually assumed to be normally distributed. However, it is generally accepted that a non-normal innovation distribution is needed in order to account for ... -
Garlic extract nanoformulation intended for broiler growth performance

Gas separation of steam and hydrogen mixtures using an ?-alumina-Alumina supported NaA membrane
(North-West University, 2007)In this study, the feasibility of a NaA zeolite membrane for the gas phase separation of steam and hydrogen mixtures was determined. The Fischer-Tropsch (FT) process, which produces high value fuels and chemicals from coal ... -
Gas utilization in Nigeria : an economic comparison of gas-to-liquid and liquefied natural gas technologies
(North-West University, 2008)Natural gas is a versatile resource that can be used as a fuel or as a feedstock for conversion to higher priced products. Nigeria has a huge natural gas reserve of about 187 trillion cubic feet (TCF) and the drive to ... -
Gasification and combustion kinetics of typical South African coal chars
(2015)An investigation was undertaken to compare the kinetics of combustion and gasification reactions of chars prepared from two South African coals in different reaction atmospheres: air, steam, and carbon dioxide. The two ... -
Gasification kinetics of blends of waste tyre and typical South African coals
(2015)With increasing energy demand globally and, in particular, in South Africa coupled with depletion of the earth’s fossil energy resources and growing problem of disposal of nonbiodegradable waste such as waste tyres, there ... -
