Description: The study of the ionosphere over the sunrise period is necessary for an understanding of the vtiriations in layer structure with time and has been a topic of research of many workers. On the whole these investigations have been restricted to a study of critical frequency variations with relatively short intervals of a few minutes between successive records, of N-h curves deduced from ionograms with long intervals (15 minutes or so) between successive N-h curves or of continuously monitored single frequency reflections. Not one of the three techniques is entirely satisfactory for a detailed study of ionospheric behaviour over sunrise. The first two do not give a sufficiently clear indication of what happens in the initial stages of layer development, while from the third incomplete data is obtained as to what is happening at a specific electron-density level. For this reason a preliminary investigation of the ionosphere over sunrise was made at Rhodes University during August, 1959. The records were obtained at four-and-a-half minute intervals and scaled by the method of KELSO (1952 ). "Many of t he results were inconclusive but it appeared that records would have to be taken at approximately one minute intervals and reduced to N-h curves by a scaling technique which made full allowance for low-level ionization if useful results were to be obtained. An attempt has been made in this thesis to investigate the behaviour of the ionosphere over sunrise more fully than can be done by the three techniques referred to. A number of observed phenomena are also examined. Part I deals with the theoretical background to ionosphere physics in general and describes the equipment, equipment modifications and experimental procedure. Part II presents the results obtained. The records for a largescale travelling disturbance are analysed. Various observed phenomena are described and discussed. A simple method of obtaining production rates from experimental data is described. The implications of the observed variations of production rates with height and time are discussed. Suggestions for further research and improvement of the methods used arc made in Charter 9.

Description: In only few cases is anything definite known about the reproduction of Clingfishes. Probably all produce eggs, in some cases (see Eckloniaichthys below) this somewhat abnormally follows internal fertilization by copulation. In those cases that have been studied the eggs are laid in a single layer and are strongly adhesive to the surface of the rock, weed or shell on which they are deposited. The number of eggs varies from about a dozen to many hundreds. The female of the large South African Chorisochismus dentex has been observed to guard the eggs and to assist aeration by fanning. In some species there is marked sexual dimorphism in body shape and in dentition, while males may have a large genital papilla. , Rhodes University Libraries (Digitisation)

The meaning and connotation of the root [Hebrew characters] in the Old Testament

- Craig, Glen Stuart

Authors: Craig, Glen Stuart
Date: 1964
Subjects: Hebrew language -- Roots , Bible -- Criticism, Textual
Language: English
Type: Thesis , Bachelor , BDiv

Description: In Chapter One, mention is made of certain features of Old Testament study which should be kept in view in any study such as this. e.g. The Old Testament is a book about God and His relation to man. It is essentially practical in its thought. The conception of Corporate Personality was very fully developed in Israel, and needs to be borne in mind, particularly for an understanding of pre-exilic Israel. Then, too, the Old Testament Is not homogenous in thought, but is virtually a library of books by different authors, written at different times, and in different circumstances. Chapter Two begins with a brlef survey of the relation of the Hebrew root [Hebrew characters] to other Semitic languages with basic connotations. ThIs is followed by a long and detailed analysis of the use of the root [Hebrew characters] in the Old Testament. In this section, the use of the various grammatical forms - the Verb (Qal, Pi'ēl and Riph'îl), Adjective and Noun, are examined with reference to men and animals, in their metaphorical use and in certain set phrases. Throughout an attempt is made, according the context, to differentiate between its use with the following connotations: being animated, purely physical existence, activity, revival from ill- health, revival from death, and general prosperIty and welfare. The section is concluded with a brief analysis of some words used as parallels to the root [Hebrew characters]. Bearing in mind that the main purpose of this thesis is to try to discover whether, as used in the Old Testament, the root has any deeper significance, an examination is made in Chapter Three of its use in the context of various relationships. After touching briefly on relationships of animals, a detailed study is made of relationships entered into by man; first in a general sense and then more specifically in the context of Election, Covenant, Cultus and Holy Places, as governed by the Torah and finally, as enjoined by Wisdom teachlng. Although relationships between men and other men, and between men and animals, are discussed, the main emphasis is always on the relationship between man and God. The conclusion drawn is that the root [Hebrew characters] is used to denote an intimate relationship between God and man - a relationship though, in which God is by far the more senior partner. Chapter Four is a brief study of the development of a belief in an After-Life in the Old Testament, emphasizing only those aspects which are relevant to the purpose of this Thesis. A brief description of early beliefs in an After-Life is followed by a discussion of tho Prophetic influence and the resistance to any such belief until after the Exile. Post-exilic developments, which took the Hebrews almost to the point of belief in a life after death, are discussed under the headings: "The Problem of Reward and Retribution" and "The Religious need for God". Finally a brief examination is made of the two late passages in the Old Testament where definite reference is made to a life after death. The Root, [Hebrew characters], it is concluded, is used to describe the deepest of all experiences of men - everlasting fellowship with God.

The meaning and significance of intercessory prayer for the Christian

Description: [From Introduction] ‘It is a difficult and even formidable thing to write on prayer, and one fears to touch the Ark. Perhaps no one ought to undertake it unless he has spent more toil in the practice of prayer than on its principle. But perhaps also the effort to look into its principle may be graciously regarded by Him who ever liveth to make intercession as itself a prayer to know better how to pray'. So wrote P.T.Forsyth in the opening chapter of his work on prayer, 1, and at the outset of this study of the meaning and significance of Christian intercession one finds oneself echoing and endorsing his words. Intercession, of course, is only a single aspect of a far greater whole. The whole, to use Francis Thompson's phrase, is a 'many-splendoured thing'. No attempt to define and designate the limits of each of the elements which together make up prayer in its Christian fulness has ever been either entirely satisfactory or generally acceptable. But roughly speaking, there are seven colours on the palette of prayer or, to change the metaphor for one used by Leslie Weatherhead, 2, there are seven rooms in the house of prayer : Affirmation or Invocation of the Divine Presence; Adoration and Praise; Confession and the penitent seeking of Forgiveness, with the Positive Affirmation and Reception of that Forgiveness; Thanksgiving; Petition; Intercession; and Meditation. There are as well the more mystical forms of prayer admirably analysed and distinguished, for example, by Bede Frost.3. In practice, no element can be isolated or divorced from the other elements which with it make up the whole. Affirmation of God's presence issues quite naturally in adoration, which in turn leads spontaneously into confession, and so on. Each aspect of prayer acts and reacts on the others. To single out Intercession (and, insofar as it is related to it, Petition) and to write on it alone would therefore seem to require some explanation.

Description: Field work and mapping with the aid of aerial photographs have shown the north Gap Dyke to be a vertical intrusion 93½ miles long . It extends from a point about 4½ miles south of Cathcart to the coast where it enters the sea about 100 yards north of the Ngadla R lver mouth. It is composed of several rock types including dolerite pegmatite, granophyric dolerite, subophitic dolerite, and it has a more or less central core of mobilized sediment at the western end. The essential minerals of the dolerite types include zoned plagioclase, which is described in some detail, and augite. Less important are hornblende and micropegmatite. Accessories include apatite, ilmenite, magnetite, quartz, actinolite, prehnite, calcite and epidote. Iddingsite (?), saussurite and chlorite occur as alteration products. The mode of origin of the Gap Dyke magma remains an open question: it may have arisen as a result of normal crystal fractionation or as the result of hybridization in depth followed by differentiation.

The South Atlantic radiation anomaly

- Van Rooyen, H O

Authors: Van Rooyen, H O
Date: 1964
Subjects: Terrestrial radiation , Atmospheric radiation , Geomagnetism , Electron precipitation , South Atlantic Ocean -- Radiation

Description: Part I. (1) An elementary treatment of the motion of charged particles in a magnetic field is presented. The concept of guiding centre motion is introduced, and is used in outlining the theory of particle drifts. (2 ) The motion of charged particles in the geomagnetic field is discussed, and the concept of adiabatic invariance introduced. (3) Mc Iliwains coordinates for mapping the distribution of charged particles trapped in the geometric field are defined and briefly discussed. (4) A survey of present knowledge of the Van Allen radiation zones is made. Particular attention is given to the distribution, characteristics, and variability of the trapped radiation. (5) The Cape Town magnetic anomaly, the Brazil radiation anomaly and the South Atlantic radiation anomaly are discussed. The electrons entering the South Atlantic radiation anomaly are shown to be those monitored over Iowa by the US satellite Injun I. Part 11. (1) It is shown how the geomagnetic field can, at high altitudes and over relatively short distances, be approximated by the field of a monopole. A new method is developed which enables one to plot the energy absorbed from an electron (which moves in a monopole field in the atmosphere) against altitude, given the initial energy and pitch angle of the electron. Some numerical computations using this method are described, and the results discussed. These results are used, in conjunction with US satellite Injun I for the Iowa region, to estimate the energy inout to the atmosphere in the South Atlantic radiation anomaly. The main approximations and simplifying assumptions made in this treatment, are discussed. (2) Geophysical effects generally recognized to be connected with the precipitation of charged particles are discussed. In the course of this discussion the two main theories of the connection between the radiation zones and the auroras are examined. (3) A preliminary discussion, based on the work summarized in point (1) of detectable geophysical events associated with the precipitation of electrons into the South Atlantic radiation anomaly is given. It is concluded that auroral emission, X-ray bursts, and ionospheric ionization in the E region should be more frequent and pronounced in the South Atlantic radiation anomaly than in any other region of comparable invariant latitudes and that the effects of atmospheric heating by precipitated electrons should be detectable over the anomaly. (4) An assessment is made of the value of the method referred to in point (1). Suggestions for its modification and extension are put forward. It is suggested that if more extensive rocket and satellite data on the low energy component of the electron flux become available, this method can be employed in a rigorous theoretical investigation of the South Atlantic radiation anomaly. Summary, p. 98-100.

The use of certain myths in the work of T.S. Eliot

Description: T.S. Eliot's statement that myth is an ordering device in literature 'is constantly belied by his use of myth in his own poems'. This is the belief of the American critic Richard Chase, noted for his work on myths and mythological themes in English and American literature. Whether or not Chase is right must emerge from the chapters which follow. The purpose will be to examine the effects of the use of myths and mythological patterns on Eliot's work in general, rather than to annotate individual mythological allusions. Simply to recognise an allusion is to raise a question, not to answer one: for we have then to decide what the writer hope to achieve by its use, and whether or not he has succeeded. Unless they lead on to such questions, lists of sources contribute little to our understanding of a work. Far more important than incidental allusions are the mythological themes and patterns on the larger scale, which reveal themselves in recurrent allusions and in basic patterns of symbolism. Again, merely to recognise such a pattern is inadequate: in every case a discovery of its function in both the poem's (or play's) structure and the poet's technique should be our main concern. ... Eliot himself has made it clear that in his case the use of myths and mythological patterns has often been a fully conscious, even self-conscious process. Therefore we may apply to his work the questions mention by Norman: what functions the myths fulfil within individual works; and why Eliot uses them in the first place. This last question leads us back to a more fundamental one; why do many writers, especially modern ones, use myths 'in the first place'? The problem involves discussion of the relation between myths and literature and of the nature of myths themselves, this forms the material of the first chapter. The other chapters will deal with some of Eliot's works, attempting to explain and analyse his use of myths in them, and to illustrate its importance in each case.
