  • Van Straaten, JF; Lotz, FJ (CSIR Division of Building Technology, 1974-10)
    The need for conserving energy is emphasised. Recommendations are made to ensure the best thermal performance under the relevant climatic conditions. Several construction methods are discussed against a thermal comfort ...
  • Beyers, ME (American Institute of Aeronautics and Astronautics, 1975)
    A technique based on superposition of tricyclic solutions has been proposed for smoothing free-flight angular motion. When incorporated into a conventional tricyclic data reduction program, the method is convenient to use ...
  • Giffen, MH (1975)
    The diatom flora from several stations on the eastern shore of Saldanha Bay (South Africa) has been studied. Saldanha bay is situated on the western coast of South Africa 110Km north of Cape Town.
  • Grobbelaar, C.S; Billinggum, P.A (NBRI/CSIR, 1975)
    The most basic function of a building is to protect its occupants and their possessions from the weather. It is no wonder therefore that a leaking root, or finishes marred by dump, leave the owner feeling cheated- his ...

    This report provides highlights on the activities and achievements of CSIR in the year 1975. An outline of the CSIR structure and financial statements are also presented in the report.
  • Hirst, SM (National Scientific Programmes Unit: CSIR, 1975-12)
    The period under review was devoted essentially to a pilot study of the Burked ecosystem, which aimed at an initial, albeit crude, quantitative appraisal of the total system to define the overall structure and the most ...
  • CSIR National Scientific Programmes Unit, CSIR (National Scientific Programmes Unit: CSIR, 1975-12)
    The savanna ecosystem project being undertaken at Nylsvley in the northern Transvaal is an attempt to improve our ability to predict events within the savanna grazing lands of southern Africa, in particular to predict the ...
  • Getz, WA; Starfield, AM (National Scientific Programmes Unit: CSIR, 1975-12)
    The construction of a linear compartmental model of the savanna ecosystem at Nylsvley is discussed. Using crude estimates for the standing crop of the compartments and intercompartmental flow rates the sensitivity of the ...
  • Scholtz, MT; Brouckaert, CJ (National Scientific Programmes Unit: CSIR, 1976)
    The flow of stable air over a general region of complex topography and non-uniform surface temperature has been investigated. In order to gain further understanding of the motion of surface air, it was necessary to study ...
  • Cawood, WN (NBRI/CSIR, 1976)
    Since primitive man first set fire to a heap of twigs to warm his cave, mankind has been making use of the earth's energy resources. Fortunately, we still have the sun, which offers us an inexhaustible source of non-polluting ...
  • Giffen, MH (1976)
    This paper deals with the continuation of an investigation of the marine littoral diatom flora of the Saldanha bay Lagoon, situated on the west coast of South Africa.
  • CSIR (CSIR, 1976)
    This report provides highlights on the activities and achievements of CSIR in the year 1976. An outline of the CSIR structure and financial statements are also presented in the report.
  • Steyn, DJ; Toerien, DF; Visser, JH (Water Research Commission, 1976-01)
    Algal bioassays indicated that the waters of Roodeplaat dam are severely eutrophied since algal growth potentials (AGP) of up to 200 mg/l and batch culture algal growth rate of up to 2,2 d were registered with selemastrm ...
  • Steyn, DJ; Toerien, DF; Visser, JH (Water Research Commission, 1976-04)
    The purpose of this study was to determine the present eutrophication levels of the Vaal dam, to determine how it might be affected by increased discharged of secondary treated sewage effluents
  • Siegfried, WR; Frost, PGH; Cooper, J; Kemp, AC (National Scientific Programmes Unit: CSIR, 1976-06)
    Data sheets are provided on 101 South African bird species thought to be eligible for conservation attention. A list is also provided of 35 species which might qualify for inclusion in a revised South African Red Data Book.
  • Nurse, RH; Symindton, NC; Brooks, GR; Dev, LJ (National Scientific Programmes Unit: CSIR, 1976-06)
    The National Programme for Environmental Sciences aims at identifying, evaluating and working towards solutions for environmental problems through cooperative studies drawing together interested scientists from various ...
  • Noble, RG (National Scientific Programmes Unit: CSIR, 1976-06)
    The importance of solid wastes management in environmental pollution control cannot be over-emphasised. Increased socio-economic development in South Africa has brought with it increasing volumes of urban, industrial and ...
  • Darracott, DA; Cloete, CE (National Scientific Programmes Unit: CSIR, 1976-06)
    The South African Committee in Oceanographic Research (SANCOR) has been requested to compile a comprehensive bibliography on marine biology in South Africa. It is hoped that it will appear in 1977. SANCOR has made funds ...
  • Cloete, CE; Oliff, WD (National Scientific Programmes Unit: CSIR, 1976-09)
    A national marine pollution survey was initiated in 1974 to determine and assess pollution around the coast of South Africa. Impact area surveys, coastal (including estuarine) reference surveys and oceanic reference surveys ...
