  • Description: That certain bacteria in the rumen of sheep and cattle are attached to solid particles in the ruminal ingesta has been known for many years. In 1942 Baker published direct microscopical evidence that bacteria were attached to cellulose food particles and to starch granules in the rumen. The sites of attachment of these bacteria corresponded to sites of disintegration of the particles when viewed by polarised light. This indicated that at least bacteria attacking solid substrates such as cellulose and starch were attached to particles of ruminal ingesta. Van der Wath (1942) found rumen bacteria attached to particles of chemically pure cellulose and of crushed maize which he suspended in separate compartments of a pure silk bag inside the rumen of sheep. The bacteria associated with the particles of cellulose were mainly Gram negative rods , while clusters of iodophilic cocci were observed in most instances around the maize kernels . The latter organisms were isolated in pure culture and found to be heat-tolerant, short-chain, Gram positive cocci fermenting glucose, maltose, and other soluble sugars as well as starch. It was thus not surprising that many years later Schwartz et al (1964) obtained evidence which suggested that bacteria metabolising soluble substrates such as glucose also showed marked attachment to solid particles of ingesta.

Shylock's origins and evolution : the image of the Jew in English literature from the middle ages to the mid-seventeenth century

  • Description: [From Preface]. Any study centred in the exploratlon and analysis of the medieval and Elizabethen images of the Jew might, with some justification. seem redundant and impertinent to a modern reader; for the third quarter of this century has witnessed the almost total obviatlon of a great many such time-honoured images and symbols. The immemorial figure of the Wandering Jew, to cite a sIngle instance, has for the past two decades, attained his country and place of destination - history no longer condemning him to tarry until the Second Coming of the Messiah. Even the deicide Jew has been granted complete absolution, by an offlcial decree from the Vatican, for his complicity in the killing of Christ. It would seem, moreover, that the atrocities perpetrated against the Jews during the course of the Second World War have resulted in an alteration of the Jewish image radically transforming It from one of contempt into one of compassion a living symbol of "man's inhumanlty to man"; and the modern European dramatist has revived the Jewlsh figure on the stage as an instance of almost personal atonement or, alternatively, as a means of scourging the state of middle-class mind which abetted the persecution of the Nazi regime, attacking state policies of inactio and deploring the failure of influentlal powers to resist the blatant inhumanlty perpetrated within Its boundaries. Max Frisch's Andorre and Rolf Hochhuth's The Representative embody, each in its own way the 2Oth century's sense of shame and horror at those events with which the century has yet to come to terms. They are both extreme reactions agalnst the image of the Jew whlch the Nazi propogandized in the 1930s. And the image which the Nazis propogandized was curiously consistent wlth the medieval and Elizabethan images of the Jew.

The constituents of the resin of Euryops floribundus. N.E.Br.

- Woolard, Graham Robert

  • Authors: Woolard, Graham Robert
  • Date: 1966
  • Language: English
  • Type: Thesis , Masters , MSc
  • Identifier: vital:4510 , http://hdl.handle.net/10962/d1013449
  • Description: The aerial portions of the plant Euryops floribundus were extracted and shown to contain Euryopsonol and another sesquiterpenoid for which the name Euryopsol is proposed. An extraction of Euryops tenuissimus contained Euryopsol only. Euryopsonol, of empirical formula C₁₅ H₂₀ O₃, was previously shown to contain a hydroxyl group and a keto-group and to be doubly unsaturated. The hydroxyl group has been shown to be secondary, while the keto-group is ⋉, β, γ, δ-unsaturated, Spectroscopic and Mass spectrosmetric measurements showed euryopsonol to possess a furan ring and to be member of the eremophilane -9 of sesquiterpenoids . These proposals were confirmed by the conversion of euryopsonol to furanoeremophilone -9, thus establishing the stereochemistry at C₄, C₅ and C₁₀. This free hydroxyl group has been placed at C₃, but its stereochemistry is still unknown. Euryopsol, of empirical formula C₁₅ H₂₂ O₄, possesses an unstable furan ring and readily undergoes autoxidation, probably to a more stable ¥-lactone. It contains two vicinal hydroxyl groups, one of which was placed by Mass spectrometry at C₉. If euryopsol possesses the eremophilane skeleton the other hydroxyl group must be at C₁₀.

  • Description: Rocks forming part of the Main-Bird Series and the Kimberley-Elsburg Series of the Upper Division of the Witwatersrand System are found in the mine. The sequence studied starts with the Middle or MB 6 Zone of the Livingstone Stage followed by the Upper or MB 5 Zone. The Vaal Roof, forming the base of the Vaal Stage, rests disconformably on the older rocks. The Stage is subdivided into the Vaal Reef Zone, the Lower Vaal Zone, the Argillaceous Zone and the Upper Vaal Zone. The lower and upper contacts of the Argillaceous Zone are gradational. The Kimberley Stage follows unconformably and comprises the basal Gold Estates Conglomerate Zone, the Denny's Zone and the Gold Estates Zone. The overlying Elsburg Stage may be subdivided into the Bastard Zone and the Upper Elsburg Zone on lithological grounds. Most of the rocks are indurated quartz wackes with only a few orthoquartzite horizons such as the Denny's Zone and the immediate hangingwall of the Vaal Reef. Microscopically the rocks consist of detrital quartz and chert grains in a fine-grained sericitic to partly siliceous matrix which may constitute more than 50 per cent of the rock. Heavy minerals, such as zircon, chromite, rutile, leucoxone, pyrite, tourmaline, epidete, apetite and magnetite, occur in most of the zones. The Vaal Reef, the economic horizon, is of small-pebble, oligomictic conglomerate, often containing thucholite seams and granules, and varying in thickness from a mere parting to more than five feet. There appears to be a correlation between greater pebble size and higher ore grade but no correlation of sorting coefficients and gold value. The mineralogy of the Vaal Reef was studied by means of polished sections and heavy mineral concentrates. The minerals identified include gold, pyrite of several ages, pyrrhotite, chalcopyrite, uraninite, galena, brannerite, gersdorffite or cobaltite, skutterudite, linnacite, danaite, niccolite, pentlandite, magnotite, zircon, chromite, rutile, leucoxine, monazite, sphalerite, tourmaline, and fluorite. From a study of the silver content of gold in the Vaal Roof it is concluded that the variations in apparent fineness are a reflection of the composition of the gold in the original source rocks. There is a definite uranium-gold relationship in the Vaal Roof. With increase in grade the amount of U₃O₈ increases but the U₃O₈:AU ratio decreases. Use of these reations may indciate the payability in cases of incomplete core recovery.The intrusive rocks were studies in detail. Six types of intrusive rocks were found. From oldest to youngest those are quartz diabase (of three varieties), amygdaloidal diabase, ilmenite mela-microdiorite, mottled microdiorite, olivine lamprophyre and ankeritic beforsite, ranging in age from Lower Ventersdorp to post-Karroo. Most of the intrusives are highly altered due to the effects of regional metamorphism and deuteric alteration. Later formations, such as the Langgeleven and Allanridge Formations of the Ventersdorp System and the Black Roof and Dolomite Series of the Transvaal System, occur on the property. The various formations have been subjected to faulting and folding.

The imagery of night: the significance of night in artistic images and philosophies

- Matthews, Thomas

  • Authors: Matthews, Thomas
  • Date: 1966
  • Subjects: Night in art
  • Language: English
  • Type: Thesis , Masters , MA
  • Identifier: vital:2455 , http://hdl.handle.net/10962/d1007616 , Night in art
  • Description: Introduction: At first glance, darkness is merely the absence of light, and is therefore negative; hence the traditional equation of night with death, evil and the creatures of the underworld. But a closer study will reveal that darkness is also a positive force; examples can be cited from various cultures where darkness was thought to have given birth to light. The subterranean is the realm of fertility; the worshippers of Dionysius realised this, as did the followers of the world-wide cult of the Great Earth Mother. The realm of darkness is also the habitat of the mystic. In this essay, we will attempt to define the nature of nocturnal imagery, and to trace the various ways in which mankind has sought to reconcile himself with the powers of darkness.

The morality play as prelude to Elizabethan drama

  • Description: Although it is generally accepted that the Morality Plays greatly influenced Elizabethan drama, this statement is often followed by the rider that they are dull and lifeless and that their chief legacy is a sense of moral earnestness which also characterises the best Elizabethan drama. The aim of this thesis has been to read the Morality Plays closely and in an appreciative spirit in order to find out what significant contribution they do make to the techniques of Elizabethan drama and to a proper understanding of it. Chapter I discusses the earliest complete Morality, The Castle of Perseverance, which is the longest and most comprehensive of all the Moralities. The chapter tries to show what a Morality is about and how it differs from the great mediaeval cyclus, the Mystery Plays. It is also an attempt to relate the early Morality Play to other mediaeval literature and to show that it is closely linked to the homeletic literature of the period. Chapter II is a study of three Moralities of the period 1500- 1520. There are fewer Moralities in this period and the plays chosen show a marked similarity to The Castle of Perserverance in their structure, although they differ from the earlier Moralities in their attitude to their subject matter and in their portrayal of the different allegorical characters. The plays under discussion are Nature, Mundus et Infans and Magnyfycence Chapter III; the period after 1535 was a period of great political and religious upheaval and this chapter discusses the plays written for propaganda purposes in the strife between Catholic and Protestant. John Bale's Three Laws, an anti-Catholic play, was chosen because Bale is a startlingly original dramatist who makes use of techniques derived from the liturgy and from emblematic devices, and because he tries to mould the Mystery Plays and the History Plays into a Morality framework. The other plays The Conflict of Conscience was chosen because of its affinity to Dr Faustus and also because it tries to show the psychomachia in psychological, personal terms rather than in a general allegorical manner. Chapter IV discusses three later Moralities, Cambyses, Horestes and Appius Virginia, which portray historical or fictional characters in situations of conflict. They were chosen because they seem to show that the Morality Plays laid the bases for the Elizabethan tragic situation and the Elizabethan tragic hero. With such diverse material, it is difficult to trace a clear line of development from one play to the next, but each group of plays has its own contribution to make to our understanding of Elizabethan drama.

The priesthood of all believers : a re-statement

  • Description: From Preface: In this age of ecumenical discussion it has becone necessary for all Christian communions to examine afresh their traditional beliefs. This has frequently led to restatement and reformulation of such traditional beliefs. It has also driven us back to seek new light from the Biblical sources. It seemed that such a re-examination of the traditional doctrine of the priesthood of all believers was necessary so that those who claim to hold it know what they hold, and so that those who do not may know what it is that their fellow-Christians believe, and why. This was the first reason for this study.

The salinity tolerance of some Eastern Province fish in relation to their known distribution

  • Description: The tolerances to sea water, sodium chloride and sodium sulphate of various cichlid, cyprinid and anabantid species which occur naturally in or near the Eastern Province region of Southern Africa, were determined, and correlated with their distribution ranges. Of the nine freshwater species tested, only Tilapia mossambica is able to disperse through the sea and is therefore the only member of the secondary division (Myers 1937) present in this region. The remaining species are possibly all limited to the use of freshwater links for dispersal between river systems. Death of fish in sea water and in sodium chloride is chiefly due to loss of osmotic control, but in solutions of sodium sulphate a pronounced toxic effect is responsible for death. In all the solutions used, an inverse relation between survival time and concentration is present. No evidence of any cells specialised for salt excretion was found in the gills of fish exposed to various salt concentrations.

  • Description: The chemical reactivity of a solid is influenced to a marked degree by the presence of imperfections or defects in the solid. Bond strengths are considerably weaker at points of imperfection than elsewhere in the solid, and hence the initiation of reaction is favoured at these sites due to the relative ease of bond rupture. Line defects, such as edge or screw dislocations, jogs, Smekul cracks etc, are of prime importance in such changes. The surface of a solid or in intergranular boundaries, where a state of strain exists, are also favourable places for the initiation of a reaction, Point defects e.g. vacancies or interstitialions or atoms also play important roles in chemical change, often in conjuction with line defects.
