    Abdominal decompression: a monograph
    (1963) Heyns, O. S.
    A short explanatory foreword to this monograph appears imperative. Abdominal decompression is the device offered for study and consideration to the reader of the following pages. If that reader accepts, for various cogent reasons, that abdominal decompression has certain effects upon the human organism— these being beneficial—and wishes to try its application, this is simple. Nothing is needed beyond the knowledge that the atmospheric pressure around the human trunk is to be reduced by one to three pounds a square inch of surface. The reader can then improvise some simple equipment and observe the effects of decompression upon him- or herself, upon another laboratory subject or on a patient who is pregnant, in labour, or suffering from menstrual pain or ordinary acute backache. The present work is but a record of the observable phenomena and their variations : matters which can be ascertained independently by the reader. As there is a wide range of application of the method and much time is needed to put possibilities to the test, an experimenter will be saved two years of work if he or she sets out equipped with the knowledge at present available.

    The active failure of embankments of cohesionless materials
    (1965) Marais, G. v. R. (Gerrit van Rooyen)
    There are two methods available for the calculation of the disturbing forces in the active failure by sliding embankments of cohesionless material. The first is due to Hummel & Finnan (1921) and Trollope (1951) and the second is due to Rendulic (1938). Using these two methods in the stability analysis of a sliding failure of a 260 ft high earth dam at Cullinan, South Africa, showed that there was a significant difference in the horizontal thrusts as determined by the two methods.

    Observations on intermediary metabolism in the human forearm
    (1962) Rabinowitz, David
    Th.e energy mechanisms present in skeletal muscle have been extensively studied by biochemists using in vitro system s. (Per example see 1, 2, 3). By contrast, attempts to quantify skeletal muscle metabolism in situ — and thereby to establish the pattern of energy metabolism in use, rather than that which is potentially available — have been relatively Infrequent. While the human forearm is undoubtedly composed of a number of different tissues, by far its greatest bulk is skeletal muscle. Correctly used, it provides a readily accessible tool for the appraisal of skeletal muscle metabolism in situ. The material to be presented in this dissertation describes the results of studies of basal metabolism of skeletal muscle and adipose tissue in the human forearm in control subjects and in individuals in whom metabolism was altered either by obesity or by endocrine disease. The studies are based upon the application of, and strict adherence to the principle outline by Pick in 1870 (4).

    Studies on lactobacilli
    (1968-05) De Klerk, Henry Charles.
    The incidence of dental caries in South Africa is high (Ockerse, 1947) and in 1955 the Minister of Health and Nutrition instructed his departments to appoint a committee to investigate methods by which dental health in this country could be improved. In 1957 a report submitted by this committee emphasized, among other recommendations, the need for fundamental research into dental health. The report was accepted by the Minister and implementation of its proposals was begun in the same year by the establishment of the Nutrition and Dental Health Research Group of the South African Council for Scientific and Industrial Research under the honorary directorship of Professor C.L. de Jager, Head of the Department of Oral and Dental Pathology, and Dean of the Faculty of Dentistry of the University of Pretoria.

    The geology and engineering properties of South African calcretes.
    (1969) Netterberg, F
    This report describes the results of a comprehensive investigation into the classification, distribution, composition, origin, age, and engineering properties of calcretes in South West Africa and the Republic of South Africa. Methods of prospecting for calcretes and tests and specifications for their use in road construction in these countries are also considered. All previously published information on Southern African calcretes and much of the world literature is reviewed, the results of the author's own research reported, conclusions drawn on the basis of both, and aspects worthy of further investigation indicated. 1,070 pages, 75 plates, 106 figures, 172 tables, 13 maps.

    Primaquine sensitivity: Some epidemiological and biochemical aspects
    (1962-09) Charlton, R. W.
    Plasmoquine (piasmochin, paiuaquin) was the first synthetic antimalarial drug, and it aroused a great deal of interest when it became available in 1926. Dixon (1933) estimated that at least 415 papers relating to plasmoquine hid appeared in the first 4 years following iti introduction, thereafter the volume of communications decreased somewhat,until fresh interest was stimulated by the Second world <.ar and the horean »,ar with fighting in maiariou. areas

    The role of ferritin in iron absorption
    (1967-01) Torrance, J. D.
    Although reports of the medicinal use of iron date back to ancient times it was not until the present century that the many functions of iron in the body were studied. Once started, the investigation received impetus from the seriousness of iron deficiency anaemia, a major cause of ill health throughout the world. The introduction of radio-isotope tracer techniques in 1939 greatly facilitated investigation of absorption, excretion and the metabolic pathways of iron. The tremendous amount of work already carried out has led to a fairly comprehensive knowledge of the various aspects of iron metabolism. Nevertheless, there remain wide gaps in the overall picture.
