Author:Naidoo, Darryl; Ait-Ameur, K; Litvin, I; Fromager, M; Forbes, ADate:May 2012The mode inside a laser cavity may be understood as the interference of two counter-propagating waves, referred to as the forward and backward waves, respectively. We outline a simple experimental procedure, which does not require any additional ...Read more
Author:Wokadala, OC; Ray, Suprakas S; Naushad Emmambux, MNDate:Sep 2012The occurrence of amylose–lipid complexes was determined in maize and teff starch biphasic pastes i.e. peak viscosity pastes at short and prolonged pasting times. Maize and teff starches were pasted for 11.5 and 130 min with or without added ...Read more
Author:Abia, ALK; Ubomba-Jaswa, Eunice; Momba, MNBDate:Aug 2016In most developing countries, especially in Southern Africa, little is known about the presence of diarrhoeagenic Escherichia coli (DEC) pathotypes in riverbed sediments. The present study sought to investigate the presence of DEC virulence ...Read more
Author:Krug, Marjolaine J; Swart, S; Hermes, JDate:Jun 2018Off the east coast of South Africa, robotic ocean gliders deployed in the Agulhas Current capture new data that help us better understand how energy dissipates in the ocean.Read more
Author:Swart, S; Zietsman, JJ; Coetsee, JC; Goslett, Daniel G; Hoek, A; Needham, D; Monteiro, Pedro MSDate:Dec 2016South Africa’s small pelagic fishery is an important component of the country’s commercial fisheries sector, second in value only to the demersal trawl fishery. Management of this sector relies on frequent hydro-acoustic surveys, which provide ...Read more
Author:Blanke, B; Penven, P; Roy, C; Chang, Nicolette; Kokoszka, FDate:Dec 2009This study analyzes the oceanic pathway connecting the Agulhas Bank to the southern Benguela upwelling system by means of a quantitative Lagrangian interpretation of the velocity field calculated by a high-resolution numerical simulation of ...Read more
Author:Lutjeharms, JRE; Monteiro, Pedro MS; Tyson, PD; Obura, DDate:Mar 2001In the last few decades, a great deal of work has been carried out on the nature of the oceanic circulation around southern Africa.
