A vapour-liquid equilibrium study on sub-critical systems using a static apparatus.
(2009)High pressure vapour-liquid equilibrium experiments were undertaken with a static high-pressure apparatus designed by Prof. J. D. Raal and commissioned by Prof. D. Ramjugernath. Isothermal VLE binary data data was measured ... -
Variability of radiation balance in sloped terrains and its impact on microclimatic characteristics of field crops.
(2018)Abstract available in PDF file. -
Variable sensor system for guidance and navigation of AGVs.
(2008)Automated Guided Vehicles (AGVs) depend on sensor systems to guide and navigate in manufacturing environments. The sensor system must ensure the correct path is followed and monitor the vehicle’s progress as it proceeds ... -
Variations in growth yield and metabolities of African ginger (Siphonochilus Aethiopicus) in response to irrigation regimes and nitrogen levels.
(2017)Medicinal plants are valuable natural resources used as traditional medicine and have economic significance. African ginger (S. aethiopicus) (Schweinf.) B.L. Burtt is one of the most important rhizomatous plants, ... -
Variations in growth, yield and metabolites of African ginger (Siphonochilus aethiopicus) in responses to irrigation regimes and nitrogen levels.
(2017)Medicinal plants are valuable natural resources used as traditional medicine and have economic significance. African ginger (S. aethiopicus) (Schweinf.) B.L. Burtt is one of the most important rhizomatous plants, highly-valued ... -
Varieties of recontextualisation in the implementation of the FET curriculum reform : a study of three schools in the Umzinyathi District KwaZulu-Natal.
(2008)This dissertation contains three schools used as the sample when conducting the study on curriculum reform implementation. This change in curriculum follows the change in the South African politics in 1994. The year 2006 ... -
Varying degrees of fear : how do large herbivores adjust their anti-predator behaviour in response to different predators?
(2016)Large predators are returning to areas where they have previously been absent through both predator reintroductions and natural range expansion. As a result, these re/introductions are changing the nature of predator-prey ... -
Varying levels of incident solar irradiance and microclimatic variations on banana (Musa spp) growth and productivity.
(2001)A field experiment was conducted at Inselele, KwaZulu-Natal South Coast, South Africa, in 1999/2000, to assess the influence of shading as related to varying levels of incident solar irradiance as well as microclimatic ... -
Varying soil nutrition in grassland and savanna ecosystems affect plant-microbe symbiosis, nitrogen nutrition and growth of Pisum sativum L.

Vector graphics to improve BLAST graphic representations
(2007)BLAST reports can be complicated. Viewing them graphically helps to understand them better, especially when the reports are long. At present "Web BLAST" and the stand-alone "wwwBLAST" versions, distributed by the NCBI, ... -
Vegetation and ant dynamics in the southern Karoo.
(1997)The aim of this thesis was to describe the structure and dynamics of ant and plant communities in the southern Karoo and to assess mechanisms of species coexistence in ant and plant communities. The role of species ... -
Vegetation change in Northern KwaZulu-Natal since the Anglo-Zulu war of 1879.
(2013)Historic photographs have been successfully used to compare landscape change over time. I used photographs taken of the grassland biome during and just after the Anglo-Zulu War (1879) in KwaZulu-Natal (South Africa), which ... -
Vegetation change over fifty years in humid grasslands of KwaZulu-Natal (Acocks's sites)
(1997)Eighty three of Acocks's sites, originally surveyed about 50 years ago, were resurveyed in 1996 to determine the extent of grassland change in the humid grasslands of KwaZulu-Natal. Sites were relocated using 1:10 000 ... -
The vegetation ecology of the lower Mkuze river floodplain, Northern KwaZulu-Natal : a landscape ecology perspective.
(2001)The overall aim of this study was to develop an understanding of the vegetation ecology of the lower Mkuze River floodplain from a landscape ecology perspective. The lower Mkuze River floodplain and its associated wetlands ... -
Vegetation succession and soil properties following the removal of pine plantations on the eastern shores of Lake St Lucia, South Africa.
(1998)Pine plantations have been established on secondary grassland on the dune systems of the Eastern Shores of Lake St Lucia, KwaZulu-Natal, South Africa for the past 40 years. These plantations have been progressively felled ... -
