The impact of livestock grazing on plant diversity: an analysis across dryland ecosystems and scales in southern Africa
(Ecological Society of America, 2014)A general understanding of grazing effects on plant diversity in drylands is still missing, despite an extensive theoretical background. Cross-biome syntheses are hindered by the fact that the outcomes of disturbance studies ... -
Impact of magnetic activity on occurrence of ionospheric amplitude scintillation over Lagos, Nigeria
(IEEE, 2017)With the increasing researches in the understanding of the ionospheric irregularities' behaviour near the magnetic equator, an attempt has been made to study the impact of magnetic activity on occurrence of Amplitude ... -
The impact of major environmental, social and economic forces on the field of industrial enigineering
(SAIIE, 2016)Every profession is bound to adapt in response to changes in the macro environments. Industrial Engineering is especially affected due to its broad application across various fields, i.e. manufacturing, customer service ... -
The impact of monetary policy on financial market in South Africa: A VAR analysis
(International Foundation For Research and Development, 2014)Like in many other countries, the South African financial market facilitates the process of raising capital by channelling funds to more productive economic activity, thereby building the nation's economy while enhancing ... -
Impact of off-road vehicles (ORVs) on ghost crabs of sandy beaches with traffic restrictions: a case study of Sodwana Bay, South Africa
(Springer Verlag, 2014)Off-road vehicles (ORVs) are popular in coastal recreation, although they have negative impacts on sandy shores. In South Africa, ORVs are banned from most coastal areas, while some areas are designated for restricted ORV ... -
Impact of ordered and disordered magnetic fields on multiwavelength emission of blazars
(IOP Publishing, 2020)We present a detailed analysis of the effects of magnetic field topology on the spectral energy distribution (SED) and spectral variability patterns (SVPs) of blazars. In order to study these effects, we have extended our ... -
The impact of particle size and maceral segregation on char formation in a packed bed combustion unit
(ELSEVIER, 2013)Highveld parent coal was crushed into three size fractions, namely: 5 mm–75 mm, 5 mm–53 mm, and 5–37.5 mm. The crushed samples were subjected as feed coals to heating in a packed-bed reactor to investigate the influence ... -
The impact of PD-LGD correlation on expected loss and economic capital
(Klute Institute, 2017)The Basel regulatory credit risk rules for expected losses require banks use downturn loss given default (LGD) estimates because the correlation between the probability of default (PD) and LGD is not captured, even though ... -
