- Description: 1) An investigation was undertaken into the various activity rhythms found in the larvae of Myrmeleon obscurus (Neuroptera, Myrmeleontidae). Pit construction was used as the criterion of activity. 2) The capacity sensitive electronic circuit used to monitor the daily pit building activity is described. 3) Various factors affecting the size of the pits constructed by ant-lion larvae were investigated. Pit size was found to be correlated with the size of the larvae, larger larvae constructing bigger pits. Population size was also shown to have an effect, since the more crowded the animals were the smaller and closer together their pits became. The death rate due to competition between the larvae also increased as the ant-lions became more crowded. 4) Feeding frequency also affected pit size. Ant-lions which were starved constructed very small pits. 5) Pit size was affected by the texture of the sand, maximal pit size being attained in sand with a grain size of between 353 μ and 211 μ. This was shown to be the most abundant grain size in sand from the natural habitat. In sand coarser or finer than this, pit size was reduced. 6) Generally smaller pits were constructed at lower temperatures, but this response depended largely on the lunar cycle. The upper and lower critical limits for pit construction were found to be 11° C and 42° C. Below and above these temperatures no pits were constructed, although the ant-lions remained alive. 7) Daily destruction of the pits decreased the pit size. 8) The existence of the daily pit building activity rhythm, which occurs at dusk, was demonstrated in individuals and in populations of ant-lion larvae. This rhythm was studied using the capacity sensitive circuit, and also by direct observation of groups of animals over a 24 hour period. 9) The daily activity rhythm appeared to be endogenous, since it continued for at least a month both in constant light and in constant dark. The rhythm was altered by reversals in the daily light-dark cycle, and it was concluded that light was the main phase setting factor. 10) An attempt was made to determine the location of the "clock" or "clocks" controlling the daily activity rhythm. This was investigated by chilling the heads of individual ant-lions with a fine copper wire, and also by chilling large groups of animals in the refrigerator. From these experiments no definite conclusions could be drawn about the location of the "clock". 11) The existence of a lunar pit building cycle was demonstrated in both field and laboratory populations of ant-lions. Maximal pit size was attained at full moon. Very low temperatures were found to suppress these lunar peaks. 12) The lunar pit building rhythm was shown to be endogenous, since it continued for at least two months in constant dark and one month in constant light. 13) The lunar pit building rhythm of very young larvae was investigated, and it was shown that while larvae which hatched in the field appeared to possess a lunar rhythm, larvae which were hatched in the laboratory did not have a rhythm. It was therefore concluded that the light of the moon was necessary to establish the lunar rhythm. 14) Some possible explanations for the lunar cycle were investigated experimentally. It was concluded that the lunar rhythm was not related to the number of prey present at various times of the lunar cycle or to the spacing of the animals in their habitat. The lunar rhythm was shown to be due to the combination of a lunar day activity rhythm and a solar day activity rhythm. 15) Some aspects of the daily rhythm are discussed, and this rhythm is compared with those found in other insects. Probable functional reasons for the rhythm are presented. Summary, p. 133-136.

- Description: From Introduction: Act No. 40 of 1947, after nineteen years in operation has been superseded by Act No. 79 of 1965. Here an attempt will be made to establish first those conditions which, in the years preceding 1944, produced a demand, both from the general electorate, from members of the legislature and from those actively concerned with the problems of social welfare in South Africa, that appropriate legislation be promulgated to alleviate the conditions. As Act 40/1947 was drafted in an attempt to remedy antecedent conditions, so it is hoped to show that in its provisions, and their attempted execution by the organs established in terms of the Act, there may be discerned the germs of at least some of the provisions of Act 79/1965. Effects of past economic depressions as well as a more recent increased awareness of overseas conditions and thinking, coupled with the war-time atmosphere and the start of rapid industrialisation all .affected the legislation that was finally passed. The degree of unanimity amongst those who advocated control of Welfare bodies through legislation will be considered, as well as the adequacy of the means available for its enforcement. So, too, will habits of thought and action which both affected interpretation and limited co-operation on several levels, for they also are amongst the factors which, by limiting the Act's effectiveness, strengthened the demand for new legislation. Attention will also be paid to that reaction against things regarded as "foreign” which, always present in South Africa, gathered strength from the 1860's, gained expression in official quarters especially after 1948 and which, together with the policy of separate development, greatly affected activities in terms of Act 40/1947.

- Description: This thesis describes the investigation carried out on the propagation of radio pulses of frequency 4.73 Mc/s between Grahamstown and Durban. The thesis is divided into two sections - A and B. Section A consists of two chapters. The introductory chapter gives a brief account of how the existence of the ionosphere came to be known. Then follows a description of the different layers of ionization and a review of the theories that have been propounded on the formation of these layers. Chapter 2 deals with the apparatus which includes the transmitter in Grahamstown and the receiving apparatus in Durban. The receiving apparatus comprises: i) a superheterodyne receiver whose gain was high (between 130 and 140 dbs); (ii) a time delay calibrator which could measure time differences of 100 μsec fairly accurately; (iii) a 310 A Tektronix oscilloscope; (iv) a continuously running 35 mm recording camera. Section B is made up of three chapters and is concerned with the actual analysis of the data recorded. The theory of propagation of radio waves in the ionosphere is discussed in Chapter 3. The effects of the magnetic field are neglected since it is found that the error introduced would not make the results unacceptable. Chapter 4 contains the analysis of the data recorded. One summer day and one winter day are discussed in detail in order to obtain the pattern of the diurnal variations for both summer and winter. Some interesting phenomena are also dealt with. An attempt to do ray tracing was successful and the paths followed by a Pedersen and a lower ray from Grahamstown to Durban have been drawn. New topics for further research are discussed in Chapter 5. There are two appendices. Appendix I gives the time delays of all the pulses recorded and their possible identifications. An overall picture of the propagation via the various layers throughout the day (both for summer and for winter is presented in Appendix II.

- Description: This study describes the preparation, characterization and evaluation of new composite membranes with embedded dendrimer hosts and Fe/Ni nanoparticles. These new reactive membranes consist of films of cyclodextrin–poly(propyleneimine) dendrimers (β-CD–PPI) that are deposited onto commercial polysulfone microporous supports and crosslinked with trimesoyl chloride (TMC). The membranes were subsequently loaded with Fe/Ni nanoparticles and evaluated as separation/reactive media in aqueous solutions using 2,4,6-trichlorophenol as model pollutant. The morphology and physicochemical properties of the composite membranes were characterised using high-resolution transmission electron microscopy (HR-TEM), atomic force microscopy and measurements of contact angle, water intake, porosity and water permeability. The sorption capacity and catalytic activity of the membranes were evaluated using ion chromatography, atmospheric pressure chemical ionisation-mass spectrometry and UV–Vis spectroscopy (UV–Vis). The sizes of the embedded Fe/Ni nanoparticles in the membranes ranged from 40 to 66 nm as confirmed by HR-TEM. The reaction rates for the dechlorination of 2,4,6-trichlorophenol ranged from 0.00148 to 0.00250 min−1. In all cases, we found that the reaction by-products consisted of chloride ions and mixtures of compounds including phenol (m/z = 93), 2,4-dichlorophenol (m/z = 163) and 4-chlorophenol (m/z = 128). The overall results of this study suggest that β-CD–PPI dendrimers are promising building blocks for the synthesis of composite and reactive membranes for the efficient removal of chlorinated organic pollutants from water.

E .Bach, on the other hand, was always regarded as the most influential composer in the early history of the German piano sonata. Nevertheless, the existing literature on C.P.E. Bach is concerned with certain aspects or his works only or is devoted to introductory discussions. The aims of this research is to trace the development of the piano sonata and in particular the evolution of the 'sonata form' within the German Pre-Classical School. The works of W.F. Bach present the earliest stage in this development, which reaches its culmination with C.P.E. Bach. The final consolidation of the sonata form is then achieved in the piano sonatas of G. Benda.

- Description: From thesis: The Egyptian civilization was regarded by the ancients as the ultimate example of' a morally regulated way of life; their judicious political economy was the admiration of the Elians and both Pythagoras and Plato accepted it as ideal, the former in a small select society and the latter on a larger scale .However a society like this,which is accepted, and acted upon as a completed one, in which everything has been considered, (especially the education of and the habituation to it, to make it second nature), does not take the nature of spirit into consideration, because it is precisely that infinite impulse which acts in contemporary life, and changes its very form. This impulse expressed itself in Egypt in a peculiar way. One would expect that a society, which appears to have been so complete, so fixed in every way, could have no characteristic of its own. Religion, one would expect would have been introduced in the same calm peaceful way, in accordance with the regular order of things. Unlike the Chinese civilisation, where every change is excluded, and the fixedness of character recurs perpetually, this calm order in Egypt was threaded with a spirit full of stirring and urgent impulses. We have here the Oriental Massiveness in combination with the African element. It is a spirit which begins to emerge from the merely natural, without freeing itself from nature. It cannot reach free consciousness of being, it only produces this as a problem: the enigma of its being. One half emerges, the other half is hidden. The buildings of the Egyptians are half below the ground while half rises into the air. The whole country is divided into a Kingdom of life and a Kingdom of death. This, however, is in reality no division, but a unity. The fundamental conception of that which the Egyptians regarded as the essence of being, rested on the fixed character of the natural world - in particular the fixed physical cycle of the Nile and the Sun. These two elements, strictly connected, formed the basis of a very simple and unchanging mode of life. Unchanging, because there is a definite physical cycle which the Nile, in connection with the sun, pursued. The sun rises, reaches its culmination, and then retrogrades. So does the Nile.

- Description: From thesis: The Egyptian civilization was regarded by the ancients as the ultimate example of' a morally regulated way of life; their judicious political economy was the admiration of the Elians and both Pythagoras and Plato accepted it as ideal, the former in a small select society and the latter on a larger scale .However a society like this,which is accepted, and acted upon as a completed one, in which everything has been considered, (especially the education of and the habituation to it, to make it second nature), does not take the nature of spirit into consideration, because it is precisely that infinite impulse which acts in contemporary life, and changes its very form. This impulse expressed itself in Egypt in a peculiar way. One would expect that a society, which appears to have been so complete, so fixed in every way, could have no characteristic of its own. Religion, one would expect would have been introduced in the same calm peaceful way, in accordance with the regular order of things. Unlike the Chinese civilisation, where every change is excluded, and the fixedness of character recurs perpetually, this calm order in Egypt was threaded with a spirit full of stirring and urgent impulses. We have here the Oriental Massiveness in combination with the African element. It is a spirit which begins to emerge from the merely natural, without freeing itself from nature. It cannot reach free consciousness of being, it only produces this as a problem: the enigma of its being. One half emerges, the other half is hidden. The buildings of the Egyptians are half below the ground while half rises into the air. The whole country is divided into a Kingdom of life and a Kingdom of death. This, however, is in reality no division, but a unity. The fundamental conception of that which the Egyptians regarded as the essence of being, rested on the fixed character of the natural world - in particular the fixed physical cycle of the Nile and the Sun. These two elements, strictly connected, formed the basis of a very simple and unchanging mode of life. Unchanging, because there is a definite physical cycle which the Nile, in connection with the sun, pursued. The sun rises, reaches its culmination, and then retrogrades. So does the Nile.

From myth to allegory: a study of the poetry of W.H. Auden, with special reference to the poet's intention
- Authors: Bell, I M

- Subjects: Auden, W. H., (Wystan Hugh), 1907-1973 -- Criticism and interpretation
- Language: English
- Type: Thesis , Doctoral , PhD
- Identifier: vital:2290 , http://hdl.handle.net/10962/d1009514 , Auden, W. H., (Wystan Hugh), 1907-1973 -- Criticism and interpretation
- Description: The more attentively Auden's poetry is studied, the more one critical problem emerges. How can the poet of the "twenties and ' thirties be reconciled with the poet of the last three decades? "We've all got to come to terms with the later Auden" writes Professor Richard Hoggart, but he does not explain how. The man who wrote the pungent early poetry with its constant reiteration of warnings to a sick society that what was needed was " … death, death of the grain, our death, Death of the old gang … " before it could achieve "new styles of architecture, a change of heart", seems an entirely different person from the man who is on the side of Authority to-day; that is to say in so far as Auden can ever be said to be definitely on one side or another. Intro. p. 1.

Government policy and industrial location in South Africa

- Description: Governments, naturally, pursue social and political as well as economic objectives. The degree to which economic and non-economic objectives harmonise with one another without government interference, however, obviously varies a good deal according to time and place. For instance in the nineteenth century, the priorities of British governments made possible a high degree of individual freedom in the economic sphere. This century, however, as Robbins suggests, has seen a great extension of state activity in the economic sphere, for both economic and non-economic reasons. This tendency, then, is not peculiar to South Africa, but the border industries policy, largely because of its ideological associations and the degree of intervention which it seems to imply, is a particularly controversial example. Chapter 1 para 2.

Man, machines, and society: lectures in industrial sociology

- Description: The machine had been slowly developing for centuries before it became incorporated as the leading element in a new type of civilisation significantly different from any previous society or culture the world had seen. It required a particular set of circumstances to integrate it and these circumstances determine its emergence and the specific form the emergence took. We are looking at a new and complete society in which previously existing elements are rear ranged into a new pattern. Throughout this discussion the relativity of the industrial order to other aspects of the modern society must be seen; it cannot be isolated from its complex back grounds else the effects it has upon simpler societies will not be grasped. It is a complete way of life competing with other complete ways of life and, its power being greater, it substitutes where the competition takes place. It will be observed that it is not identical with a specific kind of economic order so far as it appears to be able to operate in the great capitalist states like America and Britain and yet to function as well in a socialist order. No greater mistake could be made than to confuse industrialisation with a specific economic system although, historically , its association is greater in time than with the newer forms of society of a socialist type. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: Citrus is grown as a commercial crop in several areas surrounding Grahamstown in the Eastern Cape Province of South Africa. Twelve miles South-west of Grahamstown is an orchard of about 6000 trees on the farm "Mosslands". This orchard attracted attention as the insect pests of citrus have been kept at a sub-economic level by natural biological control since 1949. This orchard is completely surrounded by indigenous bush and originally the object of this study was to see, in how far, the insect fauna of the indigenous bush was infuencing the biological control which had been achieved in the orchard. As citrus is a member of the family Rutaceae, four indigenous plants in this family, which occured in the indigenous bush, were chosen for a closer study of their associated insect fauna. This study continued for a year during which time a bewildering number of insects and their parasites were collected and it was realized that only an investigation of a very specific aspect of the problem could possibly yield meaningful results. As a starting point, therefore, Trioza erytreae (Del Guercio) (Homoptera: Psyllidae), the South African citrus psyllid, was singled out. This psyllid was found on citrus at "Mosslands" and was also found on all but one of the indigenous rutaceous plants. It was chosen for study because of its polyphagous habit and because very little is known of the biology of this economically important species in South Africa. Also very little work has been done on the Psyllidae generally. Intro., p. 1.

- Description: The eel family Congridae is now known to be represented in the western Indian Ocean (here regarded to be west of 60 E. from and including the Red Sea, to Cape Point) by 11 genera and 19 species as well as at least five distinct larval forms which have not yet been identified. More than half of these species inhabit the shallow and offshore waters of the tropical western Indian Ocean. The remainder are known only from cool-temperate waters off the Cape, with one deep-water Atlantic species and one Mediterranean species also present in this area. Considerable additions to this fauna can be expected as the deep waters off the east coast are more fully sampled. Congrina wallacei sp. nov., de- scribed here from 260-270 fathoms off southern Mozambique and Durban, has rather large teeth on the jaws, a long snout and about 168 vertebrae. At least one species spawns off the Cape, but the majority probably do so over the western edge of the oceanic basins north and south of Madagascar. The shallow-water species show strong affinities with the tropical and cool-temperate Indo-Pacific. , Rhodes University Libraries (Digitisation)
