The high performance liquid chromatography (HPLC) analysis of ultraviolet (UV) irradiated chlorophyll a and secondary plant compounds
(Academic Journals, 2011)A large number of diseases such as cancer, cardiovascular disease, inflammatory disease, neurodegenerative disorders and ageing are consequences of reactive oxygen species (ROS) and reactive nitrogen species (RNS). ... -
The high resolution melting analysis (HRM) as a molecular tool for monitoring parasites of the wildlife
(Cambridge Univ Press, 2017)In an interconnected world, the international pet trade on wild animals is becoming increasingly important. As a consequence, non-native parasite species are introduced, which affect the health of wildlife and contribute ... -
High sedentary behavior is associated with depression among rural South Africans
(MDPI, 2019)The study aimed to investigate the association between sedentary behavior and depression among rural South Africans. Data were analyzed from the cross-sectional baseline survey of the “Health and Aging in Africa: A ... -
High sedentary behaviour and low physical activity are associated with anxiety and depression in Myanmar and Vietnam
(MDPI, 2019)The study aimed to estimate independent and combined associations of sedentary behaviour and physical activity with anxiety and depression among chronic disease patients in Myanmar and Vietnam. The cross-sectional sample ... -
High sedentary behaviour and low physical activity are associated with lower health related quality of life in Myanmar and Vietnam
(Cogent OA, 2019)The study aimed to estimate independent and combined associations of sedentary behaviour and physical activity with health related quality of life (HRQoL) in Myanmar and Vietnam. The cross-sectional sample included 3201 ... -
High-energy emission from Black Widows and Redbacks
(Sissa Medialab, 2015)A large number of new black widow and redback energetic millisecond pulsars with irradiated stellar companions have been discovered through radio searches of unidentified Fermi sources. We construct a 3D emission model ... -
High-energy emission properties of pulsars
(PoS, 2017)The sheer number of new γ-ray pulsar discoveries by the Fermi Large Area Telescope since 2008, combined with the quality of new multi-frequency data, has caused a revolution in the field of high-energy rotation-powered ... -
The high-energy impulsive ground-level enhancement
(IOP Publishing, 2012)We have studied short-lived (21 minute average duration), highly anisotropic pulses of cosmic rays that constitute the first phase of 10 large ground-level enhancements (GLEs), and which extend to rigidities in the range ... -
High-energy pulsar light curves in an offset polar cap B-field geometry
(HEASA, 2016)The light curves and spectral properties of more than 200 γ -ray pulsars have been measured in unsurpassed detail in the eight years since the launch of the hugely successful Fermi Large Area Telescope (LAT) γ -ray ... -
High-energy pulsar models: developments and new questions
(Wiley, 2014)The past few years have seen a major advance in observational knowledge of high-energy (HE) pulsars. The Fermi Large Area Telescope (LAT) and AGILE have increased the number of known γ-ray pulsars by an order of magnitude, ... -
The high-energy γ-ray emission of AP Librae
(EDP Sciences, 2015)The γ-ray spectrum of the low-frequency-peaked BL Lac (LBL) object AP Librae is studied, following the discovery of very-high-energy (VHE; E> 100 GeV) γ-ray emission up to the TeV range by the H.E.S.S. experiment. This ... -
A high-fat diet exacerbates depressive-like behavior in the Flinders Sensitive Line (FSL) rat, a genetic model of depression
(Elsevier, 2011)Major depressive disorder (MDD) and diabetes mellitus type II (T2DM) are two of the major health challenges of our time. It has been shown that MDD and T2DM are highly co-morbid, and recent work has proposed a bi-directional ... -
High-glycolytic cancers and their interplay with the body's glucose demand and supply cycle
(Elsevier, 2011)Many difficult-to-treat solid cancer tumours and metastases have high-glucose uptake, usually under hypoxic conditions. Hypoxic tumours suppress the immune system and are insensitive to traditional chemoradiotherapies. The ... -
High-temperature granulites and supercontinents
(China University of Geosciences (Beijing) and Peking University, 2016)The formation of continents involves a combination of magmatic and metamorphic processes. These processes become indistinguishable at the crust-mantle interface, where the pressure-temperature (P-T) conditions of (ultra) ... -
High-temperature thermal plasma treatment of monazite followed by aqueous digestion
(SAIMM, 2016)Monazite is a chemically inert, radioactive phosphate mineral that contains the light rare earth metals (Ce, La, Nd, Pr and Y), thorium and uranium. A new process, which improves the extraction efficiency of monazite, ... -
High-throughput sequence analyses of bacterial communities and multi-mycotoxin profiling during processing of different formulations of Kunu, a traditional fermented beverage
(Frontiers Media, 2019)Kunu is a traditional fermented single or mixed cereals-based beverage popularly consumed in many parts of West Africa. Presently, the bacterial community and mycotoxin contamination profiles during processing of various ... -
High-throughput sequence analysis of bacterial communities in commercial biofertiliser products marketed in South Africa: an independent snapshot quality assessment
(Springer, 2019)The genetic and predicted functional diversity of bacterial communities in 12 commercial biofertiliser products were evaluated using high-throughput sequencing of the 16S rRNA gene. Proteobacteria, Firmicutes and Bacteroides ... -
Higher degree committee members' perceptions of quality assurance of Doctoral education: a South African perspective
(Information Science Institute, 2016)In South Africa four key policy discourses underpin doctoral education: growth, capacity, efficiency, and quality discourses. This article contributes to the discourse on quality by engaging with quality assurance from the ... -
