H.G. Stoker (1999-1993) as Christelike filosoof: ’n Historiese legende en ikoon, of nog steeds ’n kontemporêre mentor?
(OASIS, 2013)’n Tradisie, wat ’n filosofiese tradisie insluit, kan alleen lewend bly as die verhaal daarvan aan die jonger geslag oorvertel word. Daarom bied hierdie inleidende en oorsigtelike artikel aan die leser iets oor die unieke ... -
H.G. Stoker se gedagtes oor die gemeenskapsuniversiteit
(Vereeniging vir Christelike Hoër Onderwys, 2015)Die oorspesialisering binne universiteite het die taak van 'n universiteit verander. Die artikel toon aan dat talle universiteite nie meer bekend kan staan as universiteite nie, maar eintlik multiversiteite genoem moet ... -
H2 production through electro-oxidation of SO2: identifying the fundamental limitations
(RSC, 2014)Sulphur dioxide (SO2), a known industrial pollutant and pulmonary irritant, is emitted to the atmosphere in excess of 120 Mt per annum. Great strides have been taken to reduce SO2 emissions, but with the growth of ... -
H2SO4 stability of PBI-blend membranes for SO2 electrolysis
(Elsevier, 2012)For hydrogen to become a serious contender for replacing fossil fuels, the manufacturing thereof has to be further investigated. One such process, the membrane based Hybrid Sulfur (HyS) process, where hydrogen is produced ... -
H2SO4 stability of PBI–blend membranes for SO2 electrolysis
(North-West University, 2011)Alternative energy sources are needed if the current use of energy is to be sustained while reducing global warming. A possible alternative energy source that has significant potential is hydrogen. For hydrogen to become ... -

Habakkuk: a guide to prayer
(Sage, 2012)We often do not know how to pray, especially when we are faced with overwhelming questions, blatant injustice or likely disaster. The book of Habakkuk can profitably be seen as a prayer guide, especially for such times. ... -
Habitat associations of fish-parasitic gnathiid isopods in a shallow reef system in the central Philippines
(Springer, 2019)Gnathiid isopods are among the most common ectoparasitic organisms infesting marine fishes in benthic marine environments, and are best known in coral reef ecosystems. These micropredators are ecologically important, as ... -
Habitat preferences and movement of adult yellowfishes in the Vaal River, South Africa
(Academy of Science of South Africa (ASSAf), 2013)The yellowfishes of the Vaal River (Labeobarbus kimberleyensis and L. aeneus) are charismatic, socially and economically important fishes, but very little is known about their interspecies habitat preferences and movement. ... -
Habitat uncertainty explains variation in offspring provisioning strategies in a temporary pond crustacean
(Springer, 2017)In temporally variable environments producing offspring with variable phenotypes can help parents to buffer against different future environmental conditions. Freshwater zooplankton can produce clutches with eggs of different ... -
The habits of highly effective community development practitioners
(Taylor & Francis, 2011)This paper is the result of a study aimed at answering the question: ‘What makes effective community development practitioners effective?’ In it, all the articles published over a 10-year period in the Community Development ... -
Habituation time and other standardisation parameters for select behavioural tests in Flinders Sensitive Line rats
(North-West University (South-Africa), 2019)With the aim of refining experimental procedures for animal behavioural tests commonly performed in our laboratory, this study aimed to provide empiric-evidence for specific aspects of the methodological approach of select ... -

Hadronic models of blazars require a change of the accretion paradigm
(Oxford University Press, 2015)We study hadronic models of broad-band emission of jets in radio-loud active galactic nuclei, and their implications for the accretion in those sources. We show that the models that account for broad-band spectra of blazars ... -
A hadronic synchrotron mirror model for blazar - Application to 3C279
(North-West University (South Africa), 2021)Blazars are a class of Active Galactic Nuclei (AGN) that are radio loud and have a small angle between the jet and the observer's line of sight, found in the centres of elliptical galaxies. In some cases, aring events ... -
Haemolymph parameter changes in the South African Mooi River crab Potamonautes warreni during prolonged starvation
(Natl Inquiry Services Centre Pty Ltd, 2015)Animals in the wild are constrained by food resources. To understand the severity of starvation events on their biology, starvation in all its manifestations must be documented. Male Potamonautes warreni Calman crabs were ... -
Haemoprotozoans infecting near-shore catsharks (Elasmobranchii: Scyliorhinidae) off the Western Cape
(North-West University (South Africa), 2021)Little is known on blood parasites or haemoprotozoans (haemogregarines and trypanosomes) infecting elasmobranchs worldwide, and knowledge on these parasites in South African cartilaginous fishes is even more limited. Even ... -
Haemostatic markers and cardiovascular function in black and white South Africans : the SABPA study
(2015)Motivation - In the black population of South Africa, cardiovascular disease (CVD) is rapidly increasing due to urbanisation. Stroke is usually accompanied by a pro-thrombotic haemostatic profile. Changing lifestyle factors ... -
Haemostatic variables in African adolescents : the PLAY study
(North-West University, 2006)Cardiovascular disease (CVD) is a major cause of adult morbidity and mortality in developed as well as in developing countries. In black population groups, stroke is more prominent than ischaemic heart disease. This may ...
