Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 4 , A commercial haul off the Limpopo River mouth in 260 - 270 fathoms collected 35 eels of the genus Bathymyrus Alcock, 1889, described here as B. smithi sp. nov. This has a shorter head and pectoral and a more posterior dorsal origin relative to the pectoral fin than in B.echinorhynchus Alcock, 1889 from the Bay of Bengal and B.simus Smith, 1965 from the South China Sea. B.smithi is also distinct in having extra-oral rostral teeth present but less conspicuously developed, more numerous vertebrae (150 — 155, compared with about 125 — 130 in the other species) and drab coloration. An osteological study shows that, although it has certain unique features, B.smithi is very closely similar to congrids of the subfamily Anagoinae. There are valid reasons for using the term Bathymyrinae for this group of congrid eels.

Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 3 , An examination of vertebral numbers in a series of eels of the genus Moringua Gray, 1831 from the western Indian Ocean clearly indicates three species, with about 105—113, 115—125 and 153—160 vertebrae respectively. These counts are matched by proportionately shorter head and greater slenderness of body, which are not correlated with total length in each group. Lateral line pore counts and position of heart confirm the presence of three species. A study of the moringuid literature and of certain type material shows that the names Moringua microchir Bleeker, M.ferruginea Bliss and M.javanica (Kaup) may be applied to these. Aphthalmichthys abbreviatus Bleeker is almost certainly based on immature females of M.microchir and is considered a synonym. A vertebral count on the holotype of M.bicolor Kaup suggests that it may be the male form of M.javanica. Aphthal— michthys macrocephalus Bleeker is probably a synonym of M.macrochir Bleeker and the latter shows close similarities to M.raitaborua Hamilton—Buchanan. Growth in moringuids appears to be most rapid at a point a few segments in advance of the vent.

Description: [From Chapter 1]. The first point I wish to make, in fact it can be considered the primary one in this essay for what is to follow is a response to it, is that theology must be responding theology. This is a theology which takes the world seriously and responds to it in a Christian way. This is the approach we find in the New Testament: particularly in the Epistles, concrete problems and behaviour in the lives of his converts to which St. Paul responded prompted the didactic sections of his epistles. J. G. Davies supports this view in Planning for Mission "There are ... two primary realities'' he says "with which the congregation must be concerned: The Gospel of God and the world to which it is sent. 'Authentic theology' emerges out of the dialogue between the Gospel and the world." This is what Tillich calls the method of correlation. First we make an analysis of our situation and then try to relate the Christian message to the problems within it. While this compels us to rethink and reformulate many traditional Christian views, nothing "can change the substance of ... the ... answer, because this is the logos of being, manifest in Jesus as the Christ." This does not say that "we have all the answers" (in fact it will become clear that we do not), but it does express our conviction that the Christian Gospel has to do with life in all its aspects.

Description: A highly sulphated, methylated polysaccharide, aeodan, isolated from the red seaweed Aeodes orbitosa was shown to contain galactose, 2-̲̲O-methyl-D-galactose, 4-O̲-methyl-Lgalactose, 6-O̲-methyl-D-galactose, xylose, and glycerol. The polysaccharide was desulphated with methanolic hydrogen chloride. Periodate oxidation of aeodan and desulphated aeodan, followed by reduction and hydrolysis, revealed the presence of 1,4- and 1,3-linked galactose residues and 1,3-linked 6-O̲-methy l-D-galactose residues in aeodan. Treatment of aeodan with sodium hydroxide revealed that the majority of the ester sulphate groups were alkali stable. Methylation of desulphated aeodan revealed that the polysaccharide was composed entirely of 1,3 and 1,4 links. Methylation of aeodan revealed the presence of 1,3- and 1,4- linked units, 1,3-linked galactose-2-sulphate, and 1,3-linked galactose-2, 6-disulphate units in the polysaccharide. Partial hydrolysis of aeodan resulted in the isolation and characterisation of 3-O̲-D-galactopyranosyl-D-galactose and 4-O̲-ß-D-galactopyranosyl- D-galactose. A sulphated, methylated polysaccharide, phyllymenan, isolated from the red seaweed Phyllymenia cornea was shown to contain galactose, 2-O̲-methyl-D-galactose, 4-O̲-methyl L- galactose , 6-O̲-methyl -D-galactose, and xylose. The polysaccharide was completely desulphated with methanolic hydrogen chloride. Periodate oxidation of phyllymenan before and after desulphation revealed that removal of the sulphate ester groups had not produced any new adjacent hydroxyl groups. Alkali treatment of phyllymenan revealed that the ester sulphate groups were alkali stable. Methylation studies on phyllymenan revealed the presence of 1,3- and 1,4-linked units, 1,3-linked galactose-2-sulphate, and 1,3-linked galactose- 2,6-disulphate units in the polysaccharide. Partial hydrolysis of phyllymenan revealed the presence or 4-O-̲ß- D-Dgalactopyranosyl- D-galactosc, 4-O-̲ß-D-galactopyranosyl -2-0- methyl-D-galactose, a galactosylgalactose composed of D and L-galactose, and adjacent 6-O̲-methyl- and 2-O̲-methyl-D- galactose units in the polysaccharide.

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.

An analytical commentary on Act No 40 (Welfare Organisations Act) of 1947 and its relation to Act No 79 (National Welfare Act) of 1965

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.

Description: This investigation deals with three leading representatives of the North German Pre-Clasaical School. The sonatas of W.F. Bach and G. Benda have as yet received little attention. 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.
