(1977)A dense algal population is of primary importance in sewage maturation ponds for the removal of plant nutrients, especially ammonia and orthophosphate. In the Republic of South Africa and in South West Africa sudden algal ...
-
(1979-11-15)As a result of potential toxin production the blue-green alga microcystis aeruginosa is a serious problem in eutrophic impoundments in South Africa. This study reports on growth characteristics of M. aeruginosa in the ...
-
(South African Conference on Computational and Applied Mechanics, 2010-01)This study examines the results of a CFD and rotating experiment, comparing an annular and a generic end wall design for a model turbine rotor in a 1½ stage turbine at the CSIR, in an attempt to draw some conclusions ...
-
(AGU Publications, 2016-08)Analyzing eddy characteristics from a global data set of automatically tracked eddies for the Agulhas Current in combination with surface drifters as well as geostrophic currents from satellite altimeters, it is shown that ...
-
(Deutsche Physikalische Gesellschaft, 2012-05)The 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 ...
-
(Springer Netherlands, 2014-06)The Agulhas Current is a challenging region for satellite remote sensing observations. Strong evaporation rates above the current core and the Retroflection reduce the number of cloud-free observations from Infra-Red ...
-
(PRASA, 2005-11)In this paper the authors describe a new approach to rewrite rule extraction and analysis, using Minimal Representation Graphs. This approach provides a mechanism for obtaining the smallest possible rule set – within a ...
-
(Elsevier, 2012-09)The 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 ...
-
(Springer, 2016-08)In 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 ...
-
(1998-10)The review output of the project comprised three main sections, literature, gas incidents and accidents, and technical interviews with mine personnel. Literature covered combustible gas emissions in mining operations in ...
-
(Springer Netherlands, 2014)The Benguela, as a highly productive upwelling system, suffers from the occurrence of a variety of harmful algal blooms, most of which are associated with elevated biomass; a feature common to the shelf environment of ...
-
(Taylor & Francis, 2016-12)South 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 ...
-
(CSIR, 2015-10)South Africa’s exclusive economic zone (EEZ) covers over 1.5 million km2 and comprises the remote waters around the Prince Edward Islands in the Southern Ocean. The benefits of an EEZ come with the responsibility of managing ...
-
(American Geophysical Union, 2009-12)This 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 ...
-
(SASAS, 2011-09)This paper introduces the South African Weather Service's coupled ocean-atmosphere model. The paper also demonstrates the advances made in configuring an operational coupled ocean-atmosphere model in South Africa for ...
-
(Bureau for Scientific Publication, 2001-03)In the last few decades, a great deal of work has been carried out on the nature of the oceanic circulation around southern Africa. Attempts have been made to determine regional ocean-atmosphere interactions and the effect ...
-
(2006)The community’s “strength in diversity” was evident throughout the discussion diversity in terms of the members, their perspectives, interests, activities, offerings and contributions. The dynamic list of questions is a ...
-
(CSIR, 2014-01)Improving ambient air quality has proven to be a difficult task in South Africa and internationally, particularly for secondary pollutants. In order to achieve the goal of full compliance, a variety of regulatory tools are ...
-
(Elsevier Science BV, 2006-04)The Okavango basin comprises the Cuito and Cubango active catchment areas in Angola, in addition to the Kavango-Okavango non-active catchment in northern Namibia and Botswana. The Okavango River water and its ecosystem ...
-
(CSIR, National Research Institute for Oceanology, 1984-07)In this report available historical information on Olifants estuary and abiotic and biotic characteristics found in the estuary are presented. The Olifants River system was explored early in the colonization of the Cape ...
