Hydrogen storage in Ti-based coatings and Ti6Al4V alloy
(University of the Western Cape, 2016)Hydrogen has been regarded as an ideal energy carrier for future, it can be stored as a liquid in cryogenic tanks, a gas in high pressure cylinders and as solid in metal hydrides. Hydrogen storage in metal hydrides is of ... -
Hydrogenisation of metals
(University of the Western Cape, 2013)Transition metals are a group of metals which are light in weight and have high hydrogen solubility. Their interaction with hydrogen is exorthermic and this phenomenon makes them “ideal” candidates for various applications ... -
Hydrogeomorphic controls on the longitudinal distribution and dynamics of reed beds in non-perennial river systems, Western Cape, South Africa.
(University of the Western Cape, 2019)There has been a growing interest in the role of interactions between vegetation and geomorphology in shaping fluvial environments, from evolutionary to modern-process timescales. However, much of this work has mainly ... -
Hydrogeophysical characterisation of shallow coastal aquifers in the Western Cape, South Africa
(University of the Western Cape, 2017)Coastal aquifers present a key groundwater resource for freshwater supply in many coastal zones of Africa, and its availability is largely driven by the physical hydrogeological properties. An understanding of the aquifer ... -
Hydrogeophysical characterization of coastal aquifers for solution-based modeling, West Coast, South Africa
(University of Western Cape, 2021)The need to improve groundwater security remains critical especially in urban areas where demand for groundwater as an alternative source of water supply increases. Declining trends in availability of surface water because ... -
Hydrological Characterisation of Wetlands: Understanding wetlands-catchment linkages
(University of the Western Cape, 2017)This study explores the hydrological processes of selected wetlands in four different catchments in South Africa (the Nuwejaars River in the Western Cape which has the Elandsdrift-Wiesdrift wetland; the Mohlapetsi river ... -
Hydrophilic Polysulfone-Hydrogel Membrane Material for Improved Nanofiltration in Wastewater Treatment
(University of the Western Cape, 2013)Over the last decade polysulfone membranes have been demonstrated to be one of the best membrane types in wastewater treatment, especially in ultrafiltration, owing to its mechanical robustness, structural and chemical ... -
Hydrosalinity fluxes in a small scale catchment of the berg river (Western Cape)
(2008)The objective of this study was to determine the hydrosalinity fluxes associated with overland and subsurface (vadose zone) flow for different soils and land uses. For this purpose, the following data were collected during ... -
Hydrosalinity Fluxes in a Small Scale Catchment of the Berg River (Western Cape)
(University of the Western Cape, 2008)The occurrence of dryland salinity is widespread throughout semi-arid regions of the world. The sources of salts may be either rock weathering or rain deposition. Clearing of natural scrubland to make way for cultivated ... -
Hydrothermal conversion of agricultural and food waste
(University of Western Cape, 2022)The global dependence on non-renewable fossil fuels to meet energy needs cannot be sustained for a long time and it is already evident in the escalation of fuel prices over the past decade. This research was performed ... -
Hydrothermal synthesis and optimisation of zeolite Na-P1 from South African coal fly ash
(2009)Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for energy. Management of this fly ash has been a concern and various approaches for its beneficial use have been investigated. ... -
Hydrothermal synthesis and optimisation of zeolite Na-Pl from South African coal fly ash
(University of Western Cape, 2009)Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for energy. Management of this fly ash has been a concern and various approaches for its beneficial use have been investigated. ... -
Hydrothermal synthesis of hierarchical ZSM-5 with different Si/Al ratio and their evaluation as catalysts in the catalytic cracking of hexane
(University of Western Cape, 2021)Ethylene and propylene are greatly used for their importance as feedstocks for producing useful materials. Due to rise in prices and the demand of ethylene and propylene, the need to increase the selective production of ... -
Hyperactivation in human semen and sperm subpopulations by selected calcium modulators
(University of the Western Cape, 2014)A functional sperm is critical for successful fertilization in order to deliver an intact genome to the site of fertilization. It is often characterized by high motility and normal morphology. Moreover, sperm hyperactivated ... -
Hyperglycinemia in captive-bred vervet monkeys with cataracts: genetic dynamics and associations
(University of the Western Cape, 2017)A small percentage (8%) of the captive-bred vervet monkeys (Chlorocebus aethiops) maintained at Primate Unit and Delft Animal Centre (PUDAC) of the South African Medical Research Council (SAMRC) were found to have high ... -
“I am a queen”: (Re)fashioning African female identities in everyday storytelling
(University of the Western Cape, 2018)This study aims to add to the rich body of work which explores our understanding of identity performances in narratives. It explores how a close knit group of five female friends use narrative structure and strategies ... -
I am not a colour: A novella
(University of the Western Cape, 2018)Nobathembu lifts her hand and waves at her neighbour. She is watering spinach in her garden with a jug from a bucket. At age sixty-nine, her beauty shines. The sun is high on the echoes of Nyanga village – echoes of ... -
“I felt like the words became a part of me”: South African feminist live poetry and the affective encounter
(University of the Western Cape, 2023)Live poetry exists as a powerful channel through which to protest against oppressive mechanisms prevalent in society. The platform – a safe space for the voices that are often silenced in other discursive spaces – has grown ... -
I'm going back to work: perceptions and experiences of back rehabilitated clients regarding their worker roles
(University of the Western Cape, 2004)Clinical research has shown that patients experience difficulty in adjusting to their pre-morbid worker roles after they have been through a back rehabilitation programme. The pressure and competitiveness of modern day ... -
