8-(3-phenylpropyl)-1,3,7-triethylxanthine is a synthetic caffeine substitute with stronger metabolic modulator activity
(Elsevier, 2018)Caffeine is one of the most worldwide consumed methylxanthines. It is well-known for its thermogenic and cell metabolism modulating effects. Based on methylxanthines' chemical structure, 8-(3-phenylpropyl)-1,3,7-triethylxanthine ... -
8-Hydroxyquinoline as an Effective Corrosion Inhibitor for 7075 Aluminium Alloy in 3.5% NaCl Solution
(ESG, 2014)The inhibition of the corrosion of aluminium alloy in 3.5 wt.% NaCl solution by 8-hydroxyquinoline has been studied using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, scanning electrochemical ... -
8-Oxo-7,8-dihydro-2’-deoxyguanosine, reactive oxygen species and ambulatory blood pressure in African and Caucasian men: the SABPA study
(Taylor & Francis, 2014)Various studies indicate a relationship between increased oxidative stress and hypertension, resulting in increased DNA damage and consequent excretion of 8-oxo-7,8-dihydro-2’-deoxyguanosine (8-oxodG). The aim of this study ... -
A (2+1)-dimensional Korteweg-de Vries type equation in water waves: Lie symmetry analysis; multiple exp-function method; conservation laws
(World Scientific Publishing, 2016)We consider a (2+1)-dimensional Korteweg-de Vries type equation which models the shallow-water waves, surface and internal waves. In the analysis, we use the Lie symmetry method and the multiple exp-function method. ... -
A community-based HIV stigma reduction intervention for people living with HIV and their partners
(UP, 2016)The diagnosis of HIV impacts the lives and the relationships of both people living with HIV (PLWH) and their partners. The researchers aimed to describe the influence of a community-based HIV stigma reduction intervention ... -
A comparative analyses of granulometry, mineral composition and major and trace element concentrations in soils commonly ingested by humans
(MDPI, 2015)This study compared the granulometric properties, mineralogical composition and concentrations of major and trace element oxides of commonly ingested soils (geophagic soil) collected from different countries with a view ... -
A comparative analysis of the perceptions of business chambers in rural and urban South Africa on the developmental role of local government
(Czestochowa University of Technology, 2016)The local economic (LED) triangle consisting of coordinated partnerships between local businesses, government and communities is key for local regions to achieve acceptable levels of economic growth and development. From ... -
A comparative analysis of the potential protein value of some agro-industrial by-products for ruminant animals
(Tropical Agriculture, The University of the West Indies, St Augustine, 2016)This study evaluated the chemical composition, buffer N solubility and in vitro ruminal N degradability of three agro-industrial by-products; coconut (Cocos nucifera L.) seed meal (CSM), poultry by-product meal (PBPM), and ... -
A comparative study between Australian and South African university sport students volunteer motives and constraints
(2015)Volunteering plays an integral part in the success of numerous South African and Australian organisations and university students have been identified as a latent target population with the greatest potential for ... -
A comparative study of the stability of stem bromelain based on the variation of anions of imidazolium-based ionic liquids
(Elsevier, 2017)There are numerous applications of ionic liquids (ILs) particularly in biology since, some of the ILs stabilizes the protein and augment enzyme activity while some of them have opposite effect. We have explored the influence ... -
A concept analysis for improving working conditions
(UNISA Press, 2017)Improving working conditions is a concept of significance in the workplace, particularly in the public health setting. This is because working conditions in public hospitals have been described in literature as horrendous, ... -
A dimensional analysis of destination image variables in a south african context: an exploratory study
(The Social Sciences Research Society, 2016)It is generally accepted in tourism literature that destination image (DI), the importance of which is universally acknowledged, is often used as a significant element for local tourists in the choice of a vacation ... -
A dual version of Huppert's conjecture on conjugacy class sizes
(De Gruyter, 2015)In [J. Algebra 344 (2011), 205–228], a conjecture of J. G. Thompson for PSLn(q) was proved. It was shown that every finite group G with the property Z(G) = 1 and cs(G) = cs(PSLn(q)) is isomorphic to PSLn(q) where cs(G) is ... -
A game theory perspective on environmental assessment: what games are played and what does this tell us about decision making rationality and legitimacy?
(Elsevier Science Inc, 2016)Game theory provides a useful theoretical framework to examine the decision process operating in the context of environmental assessment, and to examine the rationality and legitimacy of decision-making subject to Environmental ... -
A highly resourceful magnetically separablemagnetic nanoparticles from aqueous peel extract of Bottle gourds for organic dyes degradation
(Elsevier, 2017)Present work, described the green synthesis of Pd supported Fe3O4 magnetic nanoparticles BG/Pd/Fe3O4MNPs from aqueous Peel extract of Bottlegourds (BG) which act as reducing and capping agent. Synthesized nanoparticles of ... -
A longitudinal study of the aftermath of rape among rural South African women
(American Psychological Association, 2017)OBJECTIVE: Sexual assaults against women are a global health crisis, with alarmingly high rates in South Africa. However, we know very little about the circumstances and the aftermath of these experiences. Further, there ... -
A model of collaboration between nursing education institutions in the North West Province of South Africa
(AOSIS, 2017)Background: Professional nursing in South Africa is obtained through a 4-year diploma offered at nursing colleges, or a 4-year degree in universities, and the South African Nursing Council (SANC) registered both for ... -
A multiple exp-function method for the three model equations of shallow water waves
(SpringerSpringer, 2017)In this study, we consider three model equations of shallow water waves. Shallow water equations model the propagation of strongly nonlinear waves up to breaking and run-up in nearshore zones. We perform multiple exp-function ... -
A new method for solving a coagulation-fragmentation equation
(SAS International Publications, 2016)In this paper, we study the well-posedness of a nonlinear non-autonomous integro-differential equation modeling coagulationfragmentation processes. We construct two monotone sequences of upper and lower solutions, and ... -
A new strategy for heavy metal polluted environments: a review of microbial biosorbents
