Physio-biochemical characterization of two wheat cultivars to Fusarium proliferatum infection
(University of the Western Cape, 2019)Wheat is a key global commodity in terms of acreage and tradeable value and as a staple in household diets. Many factors including biotic stress conditions have detrimental effects on global wheat production and yield. ... -
Physiological and biochemical characterization, of antimony stress, responses in Phaseolus vulgaris
(University of the Western Cape, 2018)The mining industry in South Africa is of immense importance as this sector contributes largely to the countries income. In the Limpopo province, a large production of antimony (Sb) is generated per year. Antimony (Sb) is ... -
Physiological and cellular characterization of a plant natriuretic peptide
(University of the Western Cape, 2005)Plants in the field are exposed to multiple stresses and their response to these various stresses determines their capacity to survive. Plants can use multiple signaling pathways and signals to mediate their response; for ... -
Physiological and molecular characterization of wheat cultivars to Fusarium oxysporum infection
(University of the Western Cape, 2019)Biotic stress is one of the main causes for agricultural loss of economically important cereal crops. The increasing prevalence of biotic stress inflicted by fungal species such as Fusarium has significantly reduced yields ... -
Phytochemical and antimicrobial studies on Rhus natalensis
(2011)Extracts from the root bark, stem bark, and leaves of R. natalensis were screened for antibacterial activity against standard bacterial strains; Staphylococcus aureas, Escherichia coli and Pseudomonas aureginosa, and fungi; ... -
Phytochemical and antimicrobial studies on Rhus natalensis
(University of the Western Cape, 2011)Extracts from the root bark, stem bark, and leaves of R. natalensis were screened for antibacterial activity against standard bacterial strains; Staphylococcus aureas, Escherichia coli and Pseudomonas aureginosa, and fungi; ... -
Phytochemical and biological studies of extracts from selected South African indigenous medicinal plants: Bulbine and helichrysum species
(University of the Western Cape, 2022)Medicinal plants from the Asteraceae and Asphodelaceae families are among the most widely recognized in South African traditional medicine for managing diabetes mellitus. Diabetes mellitus is a universal epidemic, yet there ... -
Phytochemical and biological studies of Helichrysum cymosum
(University of the Western Cape, 2020)Diabetes mellitus (DM) is well known as a group of systemic metabolic disorders with a considerable mortality rate around the world. Hyperglycemia is the main consequence of DM, which results from the shortage in insulin ... -
Phytochemical and biological studies on some South African plants used in traditional medicine for skin hyperpigmentation.
(University of the Western Cape, 2017)The regulation of the Western beauty care products is currently inadequate and a huge concern to consumers throughout the world, as most of the products manufactured by personal care industry are made of synthetic additives, ... -
Phytochemical studies of extracts from Aloe succotrina
(University of the Western Cape, 2017)Global climate change and geographical differences are two major parameters known to have, either, direct or indirect influence on the production of secondary metabolites in plants, which in-turn may affect the quality ... -
Phytochemical studies of Helichrysum patulum
(University of the Western Cape, 2006)Since Helichrysum is known by the indigenous people of Africa for therapeutic properties, such as against colds, flu and wounds, the aim of this study was to focus on the patulum species found predominantly in the Western ... -
Phytochemical studies on extracts of selected South African indigenous medicinal plants
(University of the Western Cape, 2022)Nature has been identified as a rich source of potentially useful chemicals. Throughout the years, phytochemical studies have led to the unearthing of a huge number of natural products, their chemical diversity is unique ... -
Phytochemical study of Rhoicissus tomentosa
(University of the Western Cape, 2008)This investigation focused on Rhoicissus tomentosa, belonging to the family, Vitaceae in an attempt to assess the phytochemistry of this plant which is widely used by traditional healers in South Africa to ensure the safe ... -
Phytochemical synthesis and antimicrobial application of gold nanoparticles from extract of Artemisia annua
(University of the Western Cape, 2023)Metallic nanoparticles synthesized using chemical methods and physical methods are considered toxic to the environment due to the use of toxic solvents. The biological synthesis methods such as the use of plant extracts ... -
Placing the dead: the spatial distribution and spread of HIV in a major South African city
(University of the Western Cape, 2005)The aim of this study was to establish a new understanding of the epidemiology of HIV/AIDS at the municipal level, but at the same time upholding the anonymity of the HIV infected and AIDS sufferers. Innovative research ... -
Plant natriuretic peptides - elucidation of the mechanisms of action
(University of the Western Cape, 2009)Several lines of cellular and physiological evidence have suggested the presence of a novel class of systemically mobile plant molecules that are recognized by antibodies generated against vertebrate atrial natriuretic ... -
Plasma characterisation of an electron cyclotron resonance ion source by means of x-ray spectroscopy
(University of the Western Cape, 2012)The ultimate aim of any multiply-charged ion source, like the Electron Cyclotron Resonance Ion Source, ECRIS, is the production of multiply-charged ions, in sufficiently large quantities. These multiplycharged ions, in the ... -
Platinum based catalysts for the cathode of proton exchange membrane fuel cells
(University of the Western Cape, 2018)Oxygen reduction reaction (ORR) is carried out in the cathode of the proton exchange membrane fuel cell (PEMFC) and it is known for its sluggish kinetics and the existence of two-pathway mechanism, related with the production ... -
Point source simulations and Foreground cleaning techniques for HI intensity mapping
(University of the Western Cape, 2018)We created a full sky point source catalogue at frequencies around 1 GHz, including the intensity, polarisation, rotation measure and spectral index of the point source. These values were matched to data where available ... -
Polarizability effects due to low-energy enhancement of the gamma-strength function
(University of the Western Cape, 2018)Physics is the study of natural phenomena. Nuclear physicists have since the discovery of the nucleus been working on understanding its dynamics. The nuclear chart, analogous to the periodic table of elements, is illustrated ...
