A case of Spousal Abuse? A study of the Marriage of Jeroboam I (1 Kings 14:1-18)
(Faculty of Theology, North West University, 2009)The biblical text introduces Jeroboam with high praise as a hayil, a man of standing (1 Kgs 11:28). However, something is wrong in his household. Using a cross-disciplinary approach incorporating a close textual reading ... -
Case study for evaluating benefits of pavement research: final results
(The National Academies of Sciences, Engineering, and Medicine, 2013)Heavy-duty pavement innovations developed through research for a major rehabilitation project in California were evaluated. The performance benefits of the innovations were examined, and the economic benefits from ... -
Case study of effect of glyphosate application on plant-parasitic nematodes associated with a soybean-maize rotation system in South Africa
(Taylor & Francis, 2019)Information on the effect of the herbicide glyphosate on nematodes in the field is limited and contradictory. A small field experiment was conducted during two consecutive summer-growing seasons to investigate the response ... -
Case study of postgraduate student dropout rate at South African universities
(Clute Institute, 2015)Public funding for higher education in South Africa is a significant investment. Large amounts of funds are invested in students and there is a national shortage of high quality students in scarce skills - in particular, ... -
A case study to determine the efficacy of ozonation in purification processes
(South African Water Research Commission, 2012)The aim of this study was to determine the efficacy of ozone in water purification processes at the Midvaal Water Company, which uses the hypertrophic Middle Vaal River for source water. It was found that pre- and ... -
Case study: Apparel industry waste management: A focus on recycling in South Africa
(International Solid Waste Association, 2010) -
Case study: energy savings for a deep-mine water reticulation system
(Elsevier, 2012)In deep level mining, water reticulation systems are one of the major consumers of electricity. The refrigeration plants, together with the underground water supply and dewatering systems are integrated to form one complete ... -
Case study: the effects of a variable flow energy saving strategy on a deep-mine cooling system
(Elsevier, 2013)Cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water to the mine as well as cooling for mine ... -
Catalogue of snout mites (Acariformes: Bdellidae) of the world
(Magnolia Press, 2016)Bdellidae (Trombidiformes: Prostigmata) are moderate to large sized predatory mites that inhabit soil, leaves, leaf litter, and intertidal rocks. They are readily recognized by an elongated, snout-like gnathosoma and by ... -
Catalysis of linear alkene metathesis by Grubbs-type ruthenium alkylidene complexes containing hemilabile α,α-diphenyl-(monosubstituted-pyridin-2-yl)methanolato ligands
(Beilstein-Institut, 2019)Four new Grubbs-type precatalysts [RuCl(H2IMes)(O^N)(=CHPh)], where [O^N = α,α-diphenyl-(3-methylpyridin-2-yl)methanolato, α,α-diphenyl-(4-methylpyridin-2-yl)methanolato, α,α-diphenyl-(5-methylpyridin-2-yl)methanolato and ... -
Catalytic dehydrogenation of the liquid organic hydrogen carrier octahydroindole on Pt (111) surface: ab initio insights from density functional theory calculations
(Elsevier, 2019)Ab initio calculations based on dispersion-corrected density functional theory were used to gain insight into the adsorption properties of reactants and products involved in the catalytic dehydrogenation of octahydroindole ... -
Catalytic dehydrogenation onset of liquid organic hydrogen carrier, perhydro-dibenzyltoluene: the effect of Pd and Pt subsurface configurations
(Elsevier, 2019)Perhydro-dibenzyltoluene (H18-DBT) is the hydrogen-rich form of the liquid organic hydrogen carrier (LOHC), dibenzyltoluene. The reversible catalytic hydrogenation and dehydrogenation of LOHCs has made them highly favored ... -
The catalytic effect of Benfield waste salt on CO2 gasification of a typical South African Highveld coal
(Springer, 2019)The possible catalytic effect of a 5% loading by mass of crystallized salt from spent Benfield solution (SBFS) was investigated and compared with the catalytic influence of a 5 mass% loading of K2CO3 on the char–CO2 ... -
