Different dietary fatty acids are associated with blood lipids in healthy South African men and women: the PURE study
(Elsevier, 2014)Background: Preliminary data from the baseline Prospective Urban Rural Epidemiology (PURE) study in South Africa indicated a higher prevalence of dyslipidemia than previous South African studies. The intake of specific ... -
Different techniques for reducing DLOFC fuel temperatures in a PBMR-DPP-400 core
(Elsevier, 2018)This article addresses the topic of modifying the fuel cycles of Pebble Bed Reactors in order to reduce their maximum fuel temperatures during Depressurised Loss of Forced Coolant (DLOFC) accidents, in order to prevent ... -
Different venues, different experiences: evidence from live music performances
(University of Stellenbosch, 2015)The purpose of this research was to determine whether visitors who attend the same live music performance at four different destinations/locations vary and whether their needs were the same for a memorable visitor ... -
A different view on evaluating the performance of bootstrap critical values
(SASA, 2012)Two methods to evaluate the performance of bootstrap-based tests are discussed. The first is one that is traditionally used in the literature, while the second is an alternative method that we propose. To illustrate ... -
Differential effect of wealth quintile on modern contraceptive use and fertility: evidence from Malawian women
(BioMed Central Ltd, 2014)Background High fertility and wide inequality in wealth distribution are phenomenal problems in sub-Saharan Africa. Modern Contraceptives (MC) are useful for limiting fertility, but are not always easily accessible in ... -
Differential effect of wealth quintile on modern contraceptive use and fertility: Evidence from Malawian women
(BioMed Central; The Open Access Publisher, 2014)Background High fertility and wide inequality in wealth distribution are phenomenal problems in sub-Saharan Africa. Modern Contraceptives (MC) are useful for limiting fertility, but are not always easily accessible in ... -
Differential effects of social isolation rearing on glutamate- and GABA-stimulated noradrenaline release in the rat prefrontal cortex and hippocampus
(Elsevier, 2020)Social isolation rearing (SIR) provides an excellent model of early life adversity to investigate alterations in brain function. Few studies have investigated the effects of SIR on noradrenaline (NE) projections which arise ... -
Differential expression of postsynaptic NMDA and AMPA receptor subunits in the hippocampus and prefrontal cortex of the flinders sensitive line rat model of depression
(Wiley, 2016)Glutamatergic abnormalities have recently been implicated in the pathophysiology of depression, and the ionotropic glutamate receptors in particular have been suggested as possible underlying molecular determinants. The ... -
Differential interaction with the serotonin system by S-ketamine, vortioxetine, and fluoxetine in a genetic rat model of depression
(Springer, 2016)Rationale The mechanisms mediating ketamine’s antidepressant effect have only been partly resolved. Recent preclinical reports implicate serotonin (5-hydroxytryptamine; 5-HT) in the antidepressant-like action of ketamine. ... -
Differential responses of resistant and susceptible groundnut genotypes at cellular level to Ditylenchus africanus
(Brill Academy Publishers, 2011)Ditylenchus africanus causes cellular breakdown in pod tissue of susceptible groundnut cultivars. The histopathology of this nematode on a resistant genotype was studied using light microscopy and compared with the ... -
Differential rotation in K, G, F and A stars
(Oxford University Press, 2016)Rotational light modulation in Kepler photometry of K-A stars is used to estimate the absolute rotational shear. The rotation frequency spread in 2562 carefully selected stars with known rotation periods is measured using ... -
Differentially susceptible host fishes exhibit similar chemo-attractiveness to a common coral reef Ectoparasite
(Springer, 2020)Gnathiid isopods are common crustacean parasites that inhabit all oceans from shorelines to depths of over 3000 m and use chemical cues to find their marine fish hosts. While gnathiids are host-generalists, hosts vary in ... -
Diffuse galactic gamma-ray emission with H.E.S.S.
(APS, 2014)Diffuse γ-ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeVenergies over several decades, assessments of diffuse γ-ray ... -
Diffuse reflectance spectroscopy versus Mexameter® MX18 measurements of melanin and erythema in an African population
(Wiley, 2016)Melanin provides protection against excess exposure to solar ultraviolet radiation (UVR) and related adverse health effects. Diffuse reflectance spectroscopy (DRS) can be used to calculate cutaneous melanin and erythema, ... -
Diffusion in pulsar wind nebulae: an investigation using magnetohydrodynamic and particle transport models
(Oxford Univ Press, 2016)We study the transport of high-energy particles in pulsar wind nebulae (PWN) using three-dimensional magnetohydrodynamic (MHD) and test-particle simulations, as well as a Fokker–Planck particle transport model. The latter ... -
Digeneans of northern fur seals Callorhinus ursinus (Pinnipedia: Otariidae) from five subpopulations on St. Paul Island, Alaska
(Springer, 2018)A parasitological survey of 651 northern fur seals Callorhinus ursinus L. from five subpopulations was conducted on St. Paul Island, Alaska, during July–August 2012–2014. Digenean trematodes were found in 210 of 651 fur ... -

The dilemma of diagnosing coenzyme Q10 deficiency in muscle
(Elsevier, 2018)Background Coenzyme Q10 (CoQ10) is an important component of the mitochondrial respiratory chain (RC) and is critical for energy production. Although the prevalence of CoQ10 deficiency is still unknown, the general consensus ... -

Diligence in determining the appropriate form of stationarity
(AOSIS, 2014)Orientation: One of the most vexing problems of modelling time series data is determining the appropriate form of stationarity, as it can have a significant influence on the model’s explanatory properties, which makes ...
