  • Description: [Summary] Chapter I . The general characteristics of solar radiation at metre wavelengths are described, with reference to data published in the literature. A brief description of some aspects of solar physics relevant to the study of solar noise is given, and the literature relating to the correlation of radio effects with solar disturbances is reviewed. Chapter II. A concise description of the apparatus constructed for the continuous recording of the flux density of solar radio noise at a frequency of 300 Mc/s is given, with some mention of difficulties experienced, and how these were overcome. Full circuit diagrams of electronic apparatus, and illustrative photographs, are supplied. Chapter III. The development of theories of the origin and propagation of solar noise radiation is historically reviewed and the success of each theory in explaining or predicting observed phenomena, is assessed. A working model is chosen from among these theories, and reasons for its adoption are given. Chapter IV. Observations made by the author of solar radiation at a frequency of 300 Mc/s are described, together with a description of the objects and methods, of analysis of the records. Chapter V. Phenomena observed by the author are compared with those observed by other workers. It is concluded that storm bursts are caused by transients similar to those producing Type II and Type ITI bursts, and a model for the production of storm bursts is tentatively suggested. Chapter VI. Suggestions for further research, including suggestions for methods of testing the author's conclusions, are made.

  • Description: Gobioid fishes are not popular with most ichthyologists, which is understandable, for most species are small to minute, and of neither commercial nor angling significance. Although almost all live in shallow water, many Gobies are so expert at concealment, that only the most thorough collecting brings them to light. Thirty years ago only 16 species were known in purely South African waters, where as in the present review, no less than 46 species are described from the South African zone, which is here taken as the area between Walfish Bay and Delagoa Bay. Critical revision of the South African species is long overdue, as the results of this review clearly reveal. Not only have there been malidentifications but also much confusion, e.g. it has been found that in nudicepts C & V, 1837, no less than four species have been confused. In addition, there have been constant new discoveries. , Rhodes University Libraries (Digitisation)

  • Description: The work described in this dissertation was undertaken in an attempt to obtain a better understanding of the causes and relationships of insecticide resistance in Blue Tick, Boophilus decoloratus Koch, which has become an acute problem in some localities of the country. The work was undertaken at the Research Department of African Explosives and Chemical Industries Limited over a period of six years from 1953 to 1958. An attempt has been made to keep up to date with the published literature on the various aspects of these investigations up until the end of 1958. Information gained from the literature subsequent to end of 1958 has been made use of but it has not been possible for a number of reasons to follow all recent developments in the various aspects of insecticide resistance published during 1959. In the execution of this work assistance has been obtained from colleagues better equipped in the field of organic chemistry, biochemistry and statistics, than the author. Where information so gained has been used it has been duly acknowledged. Considerable assistance was rendered by laboratory assistants who were responsible for performing the considerable amount of routine collection, breeding and testing of the biological material. The blue tick is not a convenient experimental organism for studies on insecticide resistance. Even with the best facilities the tick cannot be bred satisfactorily and in consequence all supplies had to be collected from naturally-occurring populations. Although this had decided advantages in some aspects of the work, a great deal of useful information might have been obtained if certain strains of ticks could have been maintained. The lack of a standard sensitive reference strain has been a considerable disadvantage which could not be overcome and which has influenced the manner in which this work has been carried out. Because the tick could not be bred artificially the work could only be undertaken with unfed larvae and fully engorged adult females . Larvae are extremely small and in consequence could only be handled in batches while the fully engorged female is sluggish and contains a large quantity of semi-digested mammalian blood which invariably interfered with chemical or biochemical studies.

  • Description: [Summary] Some properties of zirconium compounds in aqueous solution have been determined using physico-chemical techniques. Zirconium oxychloride was used as the source of zirconium in all detailed investigations; zirconium sulphate was used in a few cases for comparative purposes. The Stokes diaphragm cell method has been used to determine the diffusion coefficient of zirconium in hydrochloric acid solution. It was found that the diffusion coefficient fell progressively with time, a limiting value being reached 4 to 5 weeks after dissolving the salt, and it was demonstrated that particles in the aged solutions were more homogeneous than in freshly prepared solutions. The limiting values were concentration dependent; dilute solutions had a lower diffusion coefficient than the more concentrated solutions when measured at the natural pH. In the presence of added acid the rate of diffusion was increased until a limiting value was reached in 0.5 M acid. The addition of alkali or complexing acids reduced the rate of diffusion.

The cost of discipleship and the reward of righteousness

  • Description: CHAPTER ONE. In the Old Testament we meet with the problem of suffering and reward, and the attempts made to resolve it. It becomes the one great problem after the time of the Exile. Most commentators are agreed that it grew to hold that place in relation to the increase of importance of the individual in Hebrew thinking. While certain aspects of the problem are presented in Jeremiah, Ezekiel, Isaiah, and Psalm 73, the most important contributions are made by the Deuteronomist and the poet who wrote the Book of Job. The Deuteronomist theory presents the belief that there is a rigid correspondence between the sins of the individual and his suffering. The reply in Job makes it clear that this is not so. Job himself passes through the desperate situation of feeling deserted by God to a certain faith that whatever happens to him, God is faithful. CHAPTER TWO. Jesus' teaching on "discipleship". Basically Jesus's teaching centres around Mark 8 : 34, "Whosoever will come after me, let him deny himself and take up his cross, and follow me". The cost of discipleship from this point of view means, then, that even as Jesus Himself bears the cross for the salvation of the world, so the disciple is called upon to bear that cross in association with his Lord. Jesus offers the reward of both a present foretaste and a future consummation of eternal life, as the disciple shares in His resurrection. St. Paul's teaching of "Life in Christ". The central teaching of Paul is found in Romans 6 : 11, "Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord." The cost of discipleship is death, the death of self- will. It means being crucified with Christ. The reward of the righteous man is both a present and future participation in the risen life of Christ. CHAPTER THREE The need of man. Because man is a sinner, being estranged from God in whose image he was created, he stands in need of being reconciled to God. This he cannot do himself because, to his sin, he is not able to make the full sacrifice of his self-will. "Man requires to be put right with God because as a matter of fact he is not right." The Christ. Only in the person of the God-man is God able to effect man's resolution. Jesus, the Christ, who alone of all men did not participate in the sinfulness of man, is this God-man, realising in Himself the fact that salvation can only be wrought by one who is both God and man. The necessity of the Cross. The death of the Christ is seen to be necessary both from the side of man and from that of God. It was essential that the Christ should give His life for man; everything for His purpose of salvation turns on the will to die. He must give himself to reconcile man to God. The sacrifice of the Cross. Seen in the context of the Old Testament sacrificial system, what is important about the sacrifice of the Christ is that on the cross He offered up His life for man. The sacrifice of the Christ is both in the category of divine revelation and that of human response. It is the love of God in its utter self-offering making a way whereby the sinner might be reconciled to Him. The use of the Ransom Theory of the atonement is regarded as inadequate for expressing this cost. Basically it is a costly sacrifice because it is the self-offering of the Son of God upon the cross. CHAPTER FOUR The New Testament picture. A closer analysis is made of the New Testament teaching of discipleship, where it is seen that it is required of men that he should make, like the Christ, the costly sacrifice of himself. Soren Kierkegaard. This existential thinker felt the need of awakening men to a full recognition of the costliness of life. Despair. Man, due to his state of sinfulness is in despair, for "sin can be defined as despair at not willing to be oneself or not willing to be oneself before God." It is necessary to make the leap of faith to pass from this despair. The Three Stages. These are the aesthetical, ethical and religious stages. The individual must enter the last by making the leap of faith out of his despair; and this leap means the costly commitment of the self to the Christ. "Purify your hearts." In this book, Kierkegaard analyses man's double-mindedness. He comes to two conclusions. "If anybody would will the Good truly, then he must with knowledge of himself be ready to renounce all double-mindedness. If anybody would will the Good truly, then he must be ready to do all for the Good, and suffer for for the Good." His teaching on the cost of discipleship could be summed up thus : "The negating of one's finite self, or the negating of one's finitude means for him nothing less than the conscious sacrifice of all that is finite." Paul Tillich. Tillich deals with the ultimate problem of being and non-being, and in the "Courage to be" he develops the reactions of the individual when he is faced with the possibility of his non-being. The individual can either lose himself in his world by the courage to be as a part, or lose his world in himself by the courage to be as himself. These two forms of courage are transcended by the courage to accept acceptance, which is the ultimate courage to be, in which the individual accepts the fact that though he is sinful, yet God accepts him. This courage is the outcome of faith, which is found in an encounter with the New Being, in which the self is lost in the Christ, being found also in the Christ. The disciple surrenders himself that he may be made more truly himself. CHAPTER FIVE In this chapter an attempt is made to analyse the reward of righteousness. This reward is firstly seen to be the outcome of the life of discipleship and not its motive. Basically it is found in the new quality of life which is called eternal life. It is a reward both in the future and in the present. In the future it is the fullness of life in communion, peace and joy in the presence of God. In the present it is a foretaste of that life which is to come, a present possession in the midst of finitude of communion, peace and joy with God. Ultimately this means participation in the resurrection of the Christ. CHAPTER SIX We can conclude from this thesis, then, that Jesus the Christ is the prototype of the Christian. Discipleship is costly because it means participation in His utter self-offering of Himself; and the righteous man, who is the one who by faith commits himself to and in the Christ, is rewarded with the new quality of eternal life. The death and resurrection of Jesus the Christ are the criteria of the cost of discipleship and the reward of the righteous man.

The frontier in South African English verse : 1820-1927

  • Description: The concept of a distinctively South African poetry in English has been, and still is, derided as a "pipe dream" as part of the fallacy which stems from the desire for a "national" literature. In 1955, for instance, C.J. Harvey (in an article containing much common sense as well as sound literary judgment) denounced the self-conscious hunting for "Local Colour" which engrosses so many South African writers. Harvey claimed: "Our civilization is not "South African", except in trivial details, it is Western European, and more specifically as far as poetry written in English is concerned, English ... ". There is a serious error of emphasis here. It would be more accurate to say that our ancestors brought Western European civilization to this continent. To imagine that this civilisation has not undergone and is not still constantly suffering a subtle but far-reaching metamorphosis in Africa would be to fly in the face of reality. White South Africans do not only carry the same identity-card but they can be distinguished from Frenchmen, Englishmen or Irishmen by more than "trivial details". This thesis is an examination of some af the earliest English written in southern Africa, particularly of the verse produced by our poetasters and near-poets. It attempts, during the course of this examination, to call attention to a few of the more significant changes which have arisen as the result of the importation of Western civilsation to an African frontier. Further I hope to show some at the varying ways in which these differences affected the white pioneer and how this has been reflected in our verse since pioneering times. In this sense the Frontier may be thought of as the background against which South African English writers developed certain characteristic traits. Intro., p. 1-2.

  • Description: [From Introduction]. The thermal decomposition of solids is characterized by the formation and growth of nuclei at sites on the surface of the solid or within the crystal lattice. Such nuclear formation is favoured by disorganisation of the crystal either by mechanical damage, or by the presence of impurities. Disorganisation results in positions which have a high thermodynamic instability. The nuclei are likely to be formed initially at the corners and the edges of the crystal since these are more prone to damage. Careful handling and storage in vacuo often leads to a large reduction in their number, while deliberate scratching of the surface facilitates their production. The number of potential sites for nuclear formation is also increased by pre-irradiation with ultra-violet light, though there are indications that a different type of nucleus may be produced. Nucleation can be facilitated by pre-irradiation with electrons, neutrons, X-rays, gamma-rays and atomic particles. The nature of the nuclei is not always clearly defined, but it is generally accepted that they are composed of solid reaction products e.g. in the decomposition of barium azide and silver oxalate, nuclei of metallic barium and silver, respectively, are formed.
