Chemical aspects of human plaque and enamel
(University of the Western Cape, 1982)The ideal conditions for the use of hydrazinium sulphate as a reducing agent to determine phosphorus in dental plaque were investigated. When this method was compared to the tin (II) chloride (Kuttner and Cohen, 1927) and ... -
Chemical compositions and leaching behaviour of some South African fly ashe
(University of the Western Cape, 2008)Fly ash is the most abundant of the waste materials generated from coal combustion in coal-fired power stations. South Africa uses more than 100 million tonnes of low grade bituminous coal annually to produce cheap electricity ... -
The chemical groundwater characteristics of the Sutherland area, Northern Cape
(University of the Western Cape, 1998)The objectives of the project were to establish, identify, interpret and map the chemical groundwater composition of the area surrounding the town of sutherland' Processes that govern the groundwater chemistry of the area ... -
Chemical interactions and mobility of species infly ash-brine co-disposal systems
(University of the Western Cape, 2010)The primary aim of these coal fired industries for co-disposing fly ash and brine was to use the fly ash as a sustainable salt sink. It is therefore important to study the interaction chemistry of the fly ash-brine systems ... -
Chemical investigation of some species of Amaryllidaceae from the Greater Cape Region of South Africa as a source of bioactive compounds
(University of the Western Cape, 2020)The family Amaryllidaceae is widely distributed in the southern hemisphere. Members of the family are well known for their content of pharmacologically active alkaloids and represent an important epicentre of Amaryllidac ... -
Chemical isolation and electro-chemical characterization of antidiabetic compounds from selected South African lamiaceae plant species
(University of the Western Cape, 2020)Diabetes mellitus (DM), being one of the most common metabolic disorders with an elevated morbidity and mortality rate around the world. It is characterised by deficiency in insulin secretion or degradation of secreted ... -
Chemical pressure-induced transition of the magnetic ground state from ferromagnetic to antiferromagnetic order in CeCuGe and DyCuIn alloys
(University of the Western Cape, 2023)Rare-earth intermetallic compounds continue to attract considerable attention, due to their fundamental importance in understanding physical properties and potential applications based on a variety of phenomena. The ternary ... -
The chemical stability of betamethasone valerate and fluocinolone acetonide cream and ointment in cetomacrogol and emulsifying cream and ointment bases
(University of the Western Cape, 2002)The corticosteroids are powerful anti-inflammatory molecules but their usage is hampered by adverse effects. To minimise their adverse reactions, proprietary brands of topical corticosteroids are commonly diluted with a ... -
Chemical studies on some natural products from Myrothamnus flabellifolius
(University of the Western Cape, 2014)Crude extracts from Myrothamnus flabellifolius were fractionated through variouschromatography techniques in order to achieve satisfactory separations. Two compounds, arbutin and lupeol, were isolated from ... -
Chemical, physical and morphological changes in weathered brine slurried coal fly ash
(University of the Western Cape, 2011)Energy production from coal comes with an environmental cost because of the toxic waste produced during coal combustion such as coal ash and brine which are potential water and soil pollutants. Coal ash and brine contain ... -
Chemical, physical and morphological changes in weathered coal fly ash : a case study of brine impacted wet ash dump
(University of the Western Cape, 2011)Fly ash is the major waste material produced by power plants in the combustion of coal to generate electricity. The main constituents of fly ash are Si, Al, Fe and Ca with smaller amount of S, Mn, Na, K, and traces of ... -
Cheminformatic Approaches to Hit-Prioritization and Target Prediction of Potential Anti-MRSA Natural Products
(University of the Western Cape, 2020)The growing resistance of Methicillin-Resistant Staphylococcus aureus (MRSA) to currently prescribed drugs has resulted in the failure of prevention and treatment of different infections caused by the superbug. Therefore, ... -
