Nigerian women embrace gender equality but dislike the social change that follows
(IFE Centre for Psychological Studies (ICPS), 2017)At a particular level of analysis, the focus of gender activism is to reverse and change the status quo in which men in the society are deemed to be superior to women in certain issues and have more opportunities to do ... -
Night shift working mothers and their adolescent children's mutual perception of their relationships
(North-West University, 2010)Night shift or non-standard work continues to grow throughout the economy (Beers, 2000). Women's roles in society are changing as they find themselves having to join the work force due to economic need. South African women ... -
Night shift working mothers: mutual perceptions with adolescent children
(Elliott & Fitzpatrick, 2011)The study investigated the mutual perception of relationships between mothers with day and night shift work and their teenage children. A cross-sectional survey using purposeful sampling was used. Two groups of 35 mothers ... -
Nikkel-bevattende bimetaal-nanodeeltjies as katalisatore vir elektrochemiese watersplyting
(North-West University (South Africa), 2023)The hydrogen evolution reaction (HER) can occur in an acidic or alkaline medium. The alkaline HER is very important for water-splitting electrolysers because contamination of H2 and corrosion of the electrolysers and ... -
NiSe-Ni3Se2/multiwalled carbon nanotube composites as efficient electrocatalysts for the oxygen evolution reaction in alkaline media
(Springer, 2020)The development of effective electrocatalysts for the oxygen evolution reaction (OER) is of great importance to combat energy-related concerns in the environment. Herein, we report a one-step solvothermal method employed ... -
Nitric oxide bioavailability and cardiovascular function in children and young adults
(North-West University (South Africa), 2020)Background and motivation: The global burden of cardiovascular disease (CVD) including hypertension is ever-increasing, especially in the South African context. Nitric oxide (NO) plays a vital role in normal vascular ... -
Nitric oxide involvement in the antidepressant-like effect of ketamine in the Flinders sensitive line rat model of depression
(Cambridge Univ Press, 2015)Objective: We investigated whether the nitric oxide (NO) precursor, L-arginine, can prevent the antidepressant-like action of the fast-acting antidepressant, ketamine, in a genetic rat model of depression, and/or induce ... -
Nitric oxide production in the striatum and cerebellum of a rat model of preterm global perinatal asphyxia
(Springer, 2017)Encephalopathy due to perinatal asphyxia (PA) is a major cause of neonatal morbidity and mortality in the period around birth. Preterm infants are especially at risk for cognitive, attention and motor impairments. Therapy ... -
Nitric oxide reduction by chars derived from high ash inertinite-rich discard coals
(North-West University, 2010)An investigation was performed to determine the kinetics of nitric oxide (NO) reduction by six different chars derived from inertinite-rich low grade coals. The experimentation involving the reduction of NO was confined ... -
Nitric oxide syntase inhibition by pentacycloundecane conjugates of aminoguanidine and tryptamine
(Wiley, 2009)This paper describes the synthesis and in-vitro activity of pentacycloundecane-conjugated aminoguanidine and tryptamine analogues on nitric oxide synthase (NOS) using rat brain homogenate. Both aminoguanidine and ... -
Nitric oxide synthesis capacity, ambulatory blood pressure and end organ damage in a black and white population: the SABPA study
(Springer, 2016)Nitric oxide (NO) synthesis capacity is determined by the availability of substrate(s) such as l-arginine and the influence of nitric oxide synthase (NOS) inhibitors, asymmetric dimethylarginine (ADMA) and symmetric ... -
Nitric oxide-related markers link inversely to blood pressure in black boys and men: the ASOS and African-PREDICT studies
(Springer, 2020)Nitric oxide plays an important role in maintaining endothelial function, while increased oxidative stress may lead to nitric oxide inactivation and cardiovascular disease. If nitric oxide biosynthesis/bioavailability is ... -
Nitrocatechol derivatives of chalcone as inhibitors of monoamine oxidase and Catechol-O-Methyltransferase
(Bentham Science, 2018)Introduction: The efficacy of L-dopa in the treatment of Parkinson’s disease depends on its metabolic conversion to dopamine in the brain, however extensive peripheral metabolism of L-dopa diminishes its availability for ... -
Nitrogen fixation of legumes in different growth mediums
(2015)South Africa has an array of mining commodities which all play an integral role in our everyday surroundings, income, and most importantly, in the economy of the country. These mining activities also produce vast amounts ... -
Nitrothiazole-thiazolidinone hybrids : synthesis and in vitro antimicrobial evaluation
(North-West University (South-Africa), 2023)Tuberculosis (TB), caused by the bacterium Mycobacterium tuberculosis (Mtb), is one of the world’s most fatal infectious diseases. Annually, 10 million people fall ill with TB and 1.5 million people die from it globally. ... -
No evidence for extensions to the standard cosmological model
(American Physical Society, 2017)We compute the Bayesian evidence for models considered in the main analysis of Planck cosmic microwave background data. By utilizing carefully defined nearest-neighbor distances in parameter space, we reuse the Monte Carlo ... -
No fitness costs associated with resistance of Busseola fusca (Lepidoptera: Noctuidae) to genetically modified Bt maize
(Elsevier, 2014)A concern regarding planting of Bt crops is that their widespread cultivation could lead to evolution of insect resistance to Bt toxins. In South Africa, the noctuid maize stem borer (Busseola fusca [Fuller]), is resistant ... -
No longer in suspense: clarifying the human rights jurisdiction of the SADC tribunal
(2015)The Southern African Development Community Tribunal's (SADC Tribunal) decision in the matter of Mike Campbell (Pvt) Ltd v Republic of Zimbabwe 2008 SADCT 2 (28 November 2008) demonstrated its ability to utilise the principles ... -
No man is an island…we are connected through the atmosphere / Pieter G. Van Zyl
(North-West University (South Africa). Potchefstroom Campus, 2022)Besides the obvious (as an atmospheric chemist presenting this inaugural address) – that we are all connected through the atmosphere (i.e. we all breathe the same air) – this presentation will also focus on the other, more ... -
“No more going to Nandos”: Rudimentary statistics and venal public servants in tender adjudication
(SAAPAM, 2014)This paper advances the notion that corruption in public service is perpetrated by the corruptibility of functionaries. The psychopathology of corruption demonstrates that hominids are inherently venal and will thus ...
