Adipokines and cardiometabolic function: how are they interlinked?
(Elsevier, 2010)Objective Adipokines contribute directly to the coexistence of insulin resistance and endothelial dysfunction. Most studies focus on a single adipokine. We therefore investigated the independent relationships of leptin, ... -
Adiposity and physical activity are related to heart rate variability: the African-PREDICT study
(Wiley, 2020)Background Physical inactivity contributes significantly to the development of obesity‐related cardiovascular disease. Adiposity may lead to reduced heart rate variability (HRV), whereas increased physical activity (PA) ... -
Adjusting haemoglobin values for altitude maximizes combined sensitivity and specificity to detect iron deficiency among women of reproductive age in Johannesburg, South Africa
(MDPI, 2020)In South Africa, haemoglobin (Hb) is measured to screen for iron deficiency (ID). However, low levels of Hb are only a late stage indicator of ID. Furthermore, Hb values are generally not adjusted for altitude even though ... -
Adjustment outcomes of immigrant children and youth in Europe: a meta-analysis
(Hogrefe & Huber Publishers, 2016)Compared to natives, immigrants have been reported to display either more (migration morbidity) or fewer (immigrant paradox) adjustment problems. We examined these two perspectives using a meta-analysis from 51 studies (N ... -
Adjustment, psychological well-being and mental health of first year students in a South African university
(NAJP, 2017)The relationships among adjustment, psychological well-being, and the mental health of first year students in a South African university were assessed. We also determined if relationships differed between male and female ... -
Adjustments to the preanalytical phase of quantitative cell-free DNA analysis
(Elsevier, 2016)Evaluating the kinetics of cell-free DNA (cfDNA) in the blood of cancer patients could be a strong auxiliary component to the molecular characterization of cfDNA, but its potential clinical significance is obscured by the ... -
An administrative justice perspective on improving EIA effectiveness
(Taylor & Francis, 2020)The aim of this letter is to provide an administrative justice perspective on EIA effectiveness. EIA is described as essentially an administrative instrument, reflecting a number of principles that revolve around an ... -
Adolescent experiences of sense of self in the context of family violence in a South African community
(Taylor & Francis, 2017)This study explored the self-identity constructions of South African adolescents with a history of family violence Twelve school learners were purposively selected for the study (11 females, ages 15-18 years) They completed ... -
Adolescents' lived experiences of their pregnancy and parenting in a semi-rural community in the Western Cape
(University of Stellenbosch, 2015)This qualitative study aimed to illuminate the pregnancy and parenting experiences of adolescents from Sir Lowry's Pass Village in the Helderberg Basin. Participants were recruited through snowball sampling and participated ... -
Adolescents' precocious and developmentally appropriate contributions to their families' well-being and resilience in five countries
(Wiley, 2011)An exploratory qualitative study of 16 disadvantaged youth in 5 countries suggests that making both precocious and developmentally appropriate contributions to their families' well-being is advantageous to adolescents ... -
Adolessente se ervaring binne 'n lesbiese ouerhuis: n Pastorale–Gestaltteoretiese hulpverlening
(University of Pretoria HTS, 2015)The article describes the development of adolescents for a sense of self in a lesbian home," in order to compile guidelines for lesbian parents as well as pastoral counsellors to help "and guide adolescents to ... -

(AOSIS, 2015)The article describes the development of adolescents for a sense of self in a lesbian home, in order to compile guidelines for lesbian parents as well as pastoral counsellors to help and guide adolescents to develop a ... -
Adoption and diffusion of open source software in Tanzania: a way forward
(IST-Africa, 2013)The use of ICT in world has increased significantly in the last two decades. This increase is far pronounced in developing countries. While the use of ICT promises to be a major instrument in poverty reduction, it is clear ... -
Adoption of human resource practices within a South African small business: a case study
(World Scientific Publishing, 2012)Until recently, human resource management has been considered inappropriate and too costly for small businesses and consequently research in this direction has been at a relatively minimum level. It is also evident that ... -
The adoption of m-commerce applications: rural dwellers’s perspectives
(IADIS, 2019)In recent years, mobile applications (mobile apps) have gained widespread acceptance. Mobile apps services have effectively encircled most of the human activities, with the purpose of improving the living standard of the ... -
Adsorption and coadsorption of single and multiple natural organic matter on Ag (1 1 1) surface: a DFT-D study
(Elsevier, 2020)The nature of the interaction of low molecular weight natural organic matter (NOM) with the Ag (1 1 1) surface is of crucial importance in the environment. The low molecular weight organics used in this study are formic ... -
Adsorption and corrosion inhibition properties of N-{n-[1-R-5-(quinoxalin-6-yl)-4,5-dihydropyrazol-3-yl]phenyl}methanesulfonamides on mild steel in 1 M HCl: experimental and theoretical studies
(Royal Society of Chemistry, 2016)Six quinoxalinyl-dihydropyrazolyl-phenyl-methanesulfonamides were investigated for their adsorption characteristics and inhibition of mild steel corrosion in 1 M HCl medium. Tafel polarization measurements revealed that ... -
Adsorption and corrosion inhibition studies of some selected Dyes as corrosion inhibitors for mild steel in acidic medium: gravimetric, electrochemical, quantum chemical studies and synergistic effect with Iodide Ions
(MDPI, 2015)The corrosion inhibition properties of some organic dyes, namely Sunset Yellow (SS), Amaranth (AM), Allura Red (AR), Tartrazine (TZ) and Fast Green (FG), for mild steel corrosion in 0.5 M HCl solution, were investigated ... -
Adsorption behavior of glucosamine-based, pyrimidine-fused heterocycles as green corrosion inhibitors for mild steel: experimental and theoretical studies
(American Chemical Society, 2016)Effects of electron donating (−CH3 and −OH) and electron withdrawing (−NO2) substituents on the corrosion inhibition efficiency of four glucosamine-based, substituted, pyrimidine-fused heterocycles (CARBs) on mild steel ... -
