  • Description: In 1985, the Central Statistical Services and the Chamber of Mines ceased publishing a racial breakdown of mining industry employment. This marked the end of a statistical series that dated back for almost 100 years. Since 1985, there is no official series of racially segmented data for the mining industry, while the racial breakdown of employment in all other sectors of the economy was published up until 1992. From 1993, the Central Statistical Services introduced a new “Unspecified Race” category into its published employment data, making the identification of trends in employment and income by race less certain. The statistical information on racial issues in this submission must reflect these difficulties with the data. In respect of gold and coal mines that are members of the Chamber of Mines, the Chamber periodically has made available unpublished information on employment and total wages after 1985, grouped into “skilled employees” and “unskilled / semi-skilled employees.” Until about 1989, when legal barriers to the employment of blacks in skilled jobs were removed, the two Chamber categories reflect the old “White” and “Non-White” categories used by the Chamber before 1986. Since 1989, a small, but slowly increasing number, of skilled workers have been black, but this has not been taken into account in any of the statistics presented for the gold and the coal sectors. “Black” employment in the gold and coal mining industry thus refers to employees in Categories 1 to 8, the only groups for which the NUM currently bargains with Chamber member mines.

  • Description: Numerous experiments in recent years have indicated differences in the bioavailability of corticosteroids from seemingly identical topical dosage forms. The human blanching assay was utilized in this study to assess the comparative blanching activities of various locally manufactured proprietary corticosteroid preparations. The first experiment was performed to assess the relative blanching activities of six semi - solid preparations containing the same concentration of betamethasone 17-valerate. The preparations used were Betnovate cream and ointment, Persivate cream and ointment and Celestoderm-V cream and ointment. This was followed, in the second experiment, by the investigation of the blanching activities of two lotions containing betamethasone 17-valerate (Betnovate and Celestoderm-V) and a lotion containing betamethasone 17,21- dipropionate (Diprosone). The third experiment involved a study of six semi-solid proprietary corticosteroid-containing formulations, viz. Dermovate (clobetasol propionate) cream and ointment, Betnovate (betamethasone 17-valerate) cream and ointment and Eumovate (clobetasone butyrate) cream and ointment. This investigation was prompted by claims in advertisements in the medical media that Dermovate is therapeutically more efficacious than Betnovate which is more efficacious than Eumovate. The penultimate experiment in this study served the purpose of finding a corticosteroid-containing preparation that falls into the moderately potent group of corticosteroid formulations, as described in the United Kingdom MIMS. This preparation was used in the final experiment which was undertaken to ascertain the potency category of Florone (diflorasone diacetate) cream and ointment.

  • Description: This thesis describes the design and development of a computer-based controller together with additional hardware that greatly extends the capabilities of a Barry Research VOS-1 Chirpsounder. The measurement of the virtual height of the ionosphere as a function of frequency using pulse- and frequency-modulated carrier wave (FMCW techniques is described and the concept of the so called "digital" ionosonde is introduced. The modifications required for the standard Chirpsounder to perform as a versatile digital chirp ionosonde are discussed. Simplified block diagrams are used to describe the Controller hardware which is fully described in two comprehensive service manuals which have been included as appendices. Important aspects of the Controller software and data storage formats are described in detail. The emphasis is then placed on system capabilities. An operators' software manual which describes system initialization and operation in terms of system commands is included as an appendix. Results of tests at both Grahamstown, South Africa , and at the SANAE base in the Antarctic are presented.

  • Description: A concurrent program is one in which a number of processes are considered to be active simultaneously . It is possib l e to t hink of a process as being a separate sequential program executing independently of other processes, although perhaps communicating with them at desired pOints . The concurrent program, as a whole, can be executed in one of two ways: il ii) in true concurrent manner, wi th each process executing on a dedicated processor in a quasi - concurrent manner, where a processor's processes . time is multiplexed between single the There are two motivations for the study of concurrency in programming languages : i) concurrent programming facilities can be exploited in systems where one has more t han one processor . As technology i mproves, machines having multiple processors will proliferate ii) concurrent p r ogramming facilities may allow programs to be structured as independent , bu t co - operating, processes which can then be implemented on a single processor system . This structure may be more natural to the programmer then the traditional sequential structures. An example is provided by Conway's - 1- Clearly, languages Pascal) problem [Ben82] . by their very nature, traditional sequential- type (Fortran, Basic, Cobol and earlier versions of prove inadequate for the purposes of concurrent programming without considerable extension (which some manufacturers have provided, rendering their compilers non standard-conforming). The general convenience of high level languages provides strong motivation for their development for rea l time programming. Modula - 2 [Wir83] is but one of a number of such r ecently developed languages, designed not only to fulfil a "sequential" role but also to offer facilities for concurrent programming. Developed by Niklaus Wirth in 1979 as a successor to Pascal and Modula, it is intended to serve under the banner of a generalpurpose systems - implementation language. This thesis investigates concurrency i n Modula - 2 and takes the following form: i ) an analYSis of the concurrent facilities offered ii) problems and difficulties associated with these facilities iii) improveme nts and enhancements, including the feasibility of using Modula - 2 to simulate constructs found in other languages, such as the Hoare monitor [Hoa74] and the Ada rendezvous [Uni81]. - 2- Each section concludes with an appraisal of the work conducted in that section . The final section consists of a critical assessment of those Modula - 2 language constructs and facilities provided for the implementation of concurrency and a brief look at concurrency in Modula, Modula-2's predecessor. - Introduction. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in

East London: the creation and development of a frontier community, 1835-1873

  • Description: From Preface: Although East London exists today as one of the major ports of South Africa, the city appears to have been forgotten by historians. Little has been done to chronicle its history. In 1932, Bruce Gordon set out to initiate this research and he investigated East London's history to the end of 1865. However, Gordon's thesis, though accurate, is short and inadequate by today's standards. Furthermore, no-one continued from where Gordon left off. Several articles have been written over the previous six decades, each dealing with aspects of East London's past but these, on the whole, are inaccurate and misleading. The time is ripe, therefore, to begin again the research into the history of East London. East London owed its foundation to the state of unrest which existed on the eastern frontier of the Cape of Good Hope between 1834 and 1847. Although the geographic and climatic conditions were in the port's favour, East London remained in a suppressed condition until about 1870. It is the purpose of this thesis to examine the factors which gave rise to this truncated growth. The thesis will examine first the wider perspective of imperial and colonial policy in which East London was conceived and in which it had its early existence. The implications of this policy for East London at the various levels of the port's development will be explored in subsequent chapters. British and Cape colonial policy, however, evolved in a chronological sequence and so the examination of this policy likewise will tend to follow a chronological pattern within each chapter. The establishment of Port Rex in November/December 1836 enters into East London's story in several ways: its political development, the creation and development of the harbour on the Buffalo River, the evolution of trade, the growth of the community and the status of the black population at the mouth of the Buffalo River. It has been found necessary, therefore, to refer often to this beginning of East London's history. Although several theses have already been written which deal with topics related to British Kaffraria, none of these do more than allude to the creation and development of East London. Although, for example, the German Settlers played an important role in the growth of the port, Schnell's thesis hardly mentions the two communities at Panmure and Cambridge. The research for this thesis led me to two important and little known sources of early information, both in Cape Town. The first was the multiple volumed "Unsorted Archives" on East London which consists of reports and letters to the Resident Magistrate. It is a treasure chest of information on East London's early years. The second source was G.M. Theal's newspapers, The Kaffrarian Recorder and East London Shipping Gazette and, later, The Kaffrarian, East London's second newspaper which was believed to have been lost until copies were discovered recently in the South African Library in Cape Town. Theal, later prominent as a historian, had a clear insight into the problems which confronted the community at East London and the editorials of his newspaper make interesting reading. East London's first newspaper is, unfortunately, still lost. It was the East London Times which had its first issue in January 1863, and lasted a mere two months. It consisted of half a sheet of foolscap printed on one side, the other side being left blank, the editor of the King William's Town Gazette wrote, "'for want of room' or from lack of matter."

  • Description: Human locomotor economy and efficiency are highly variable. This study investigated the role that stature plays in this variation, by evaluating metabolic and respiratory responses to walking and running at speeds set relative to one's stature. Four groups of subjects: male, high V0₂ max (n = 11); male, average V0₂ max (n = 10); female, high V0₂ max (n = 10); and female, average V0₂ max (n = 11) were habituated to treadmill locomotion prior to the measurement of maximal oxygen consumption (V0₂ max). The V0₂ max test entailed 1 km.h⁻¹ increases per min from 3 to 6 km.h⁻¹ walking, and 7 - 17 km.h⁻¹ running then 1% grade increments per min until exhaustion. On each of four other occasions, the subject walked or ran at 6 of a variety of relative speeds - walking at 0.5, 0.7, 0.9, 1.1, 1.3; running at 1.5, 1.7, 1.9 and for selected subjects 2.1, 2.3 and 2.5 statures.s⁻¹ ,and grades - 0%, +3%, -3%. Steady-state respiratory and metabolic responses, and treadmill speed were monitored by an on-line computer system developed for this study. Cadence and RPE were also monitored. All subjects demonstrated an exponential relationship between V0₂ and walking relative speed (st.s⁻¹) (RS) . V0₂ (ml.kg⁻¹.min⁻¹ ) = 4.747 * e(1.371*RS) During running this relationship was essentially linear . The variability of economy at relative speed (9.08%) and absolute speed (9. 01%) did not differ. Male and female subjects did not differ in response to absolute speed but females were more economical at relative speeds (p<0.05). Those with high and average aerobic capacity did not differ in locomotor economy at relative speed. Higher freely-chosen stride length was associated with a higher V0₂ response as velocity increased. The V0₂ of uphill walking was 1.4 times greater than that for downhill walking (running: 1.28 times) . Stride length decreased with increasing speed in uphill locomotion but the reverse was the case for downhill. The economy and efficiency of walking was greater than that of running. Walking economy was maximal between 0.7 and 0.9 st. s⁻¹. Running economy remained essentially unaffected by increased velocity. The setting of locomotor velocity relative to stature does not minimize inter-subject variability in metabolic and respiratory response .
