- Description: War is a condition of this world. From man to the smallest insect, all are at strife, yet man has a "quality which makes him overlord of all; for whereas the creatures of the forest and plain kill only to eat, or to lead the herd ... man will kill for no reason at all. This makes him terrible among the creatures, for he is the very God of Destruction. And from man's pride in his weapons that give him power has grown his art." Warfare in its primeval state is a direct result of a natural phenomenon, springing from the discovery that certain grass seeds could be cultivated and that certain grass feeding animals could be domesticated. From these roots sprouted two very differently organised communities, the agricultural and the pastoral, who clashed for the first time in the third millenium B.C. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1968

- Description: As has been noted in the previous section little or no complex formation occurs with either formate or acetate except possibly above pH 9*0 or so. These anions do not stabilise the aluminium solutions to precipitation - they may* however, be of value in controlling pH, as solutions of these salts buffer strongly in the region pH 4 to 5. The other salts, lactate, tartrate and citrate all show tendencies to complex formation though the degree to which this occurs varies with the anion. The complexes formed by lactate at high pH must be very unstable because on the addition of acid the pH corresponds to the calculated blank. Below pH 9.0 however, the curves deviate quite considerably showing that more acid must be added to reach a certain pH value than is required by the blank. This means complex formation has occurred with loss of -COGH groups. In this system too, buffering is apparent. The same is true of tartrate but this salt is not as efficient a buffering agent. This is probably due to the fact that the excess tartrate is not available as a buffer as it is precipitated as the acid salt which is only sparingly soluble. Citrate on the other hand must form very stable complexes, the effect of which is apparent at even very high pH values. In other words, addition of strong acid liberates free -GOGH groups which are immediately incorporated in the complex. This evidently does not occur with lactate or tartrate until lower pH values are reached. The ratio of lactate and citrate to aluminium appears to have some influence on the degree of masking as greater complex formation is found to occur at the higher ratio levels. Tartrate on the other hand apparently has a fixed complex forming capacity between 1 and 4 mols/mol aluminium, since the same deviation from the blank was observed irrespective of which ratio of the masking agent to aluminium, was employed. However, at ratios of less than 1 mol tartrate/mol aluminium, deviations from the blank were reduced and less stabilisation occurs as evidenced by the formation of precipitates containing aluminium under these conditions. In view of these facts it may be suggested that 1 mol tartrate combines with 1 mol aluminium to form a complex containing equimolar proportions of aluminium and tartrate. The effect of boiling apart from one or two exceptions always has the same effect, i.e. a shift to the acid side of the curve. Free acid must have been liberated which is an indication that olation might have occurred. In the lactate and citrate series dilution appears to reduce the complex forming capacity of these ions but tartrate is unaffected. Thus it would appear that the tartrate complex is more stable than those formed by lactate. Citrate stabilises aluminium solutions with fewer equivalents than tartrate, but the complex does not contain a constant ratio of masking agent to aluminium further quantities of tartrate cannot enter the complex even in the presence of large excess of the anion probably due to the effect of steric hindrance. , Thesis (Dip) -- Leather Industries Research Institute, 1950

- Description: Earthworms of the genus Microchaetus, Rapp.1849, are abundant in the Grahams town district. Microohaetus saxatilis, Rosa, 1S98,has been chosen as a subject for investigation as it is a valuable type for laboratory work, and it showed interesting characters which required detailed study. Members of the genus Micro chaet us are available in many regions of South Africa and are useful for work in South African schools and Universities. Micro chaetus saxatills is an 01igochaete worm belonging to the family Glossoseolecidae. These wonns were originally placed in the Lumbricina by Grube, (1850 p.345), but Rosa in 1887 (p.7) formed a separate family naming it the Geoscolecidae. He divided it into two sub-families :- (1) Geoscolecinae, and (B) Microchaetinae. Beddard was studying the classification of this family at the same time as Rosa. He spelt the name slightly differently, calling the family the Geoscolicidae, but he arrived independently at the same division into subfamilies (1888, pp. £43-278), although he suggests that perhaps an additional sub-family - the Homo gas. tridae - should be formed. Homo gas ter is undoubtedly an aberrant type, and it seems strange that Rosa who studied this genus should not have placed it in a separate sub-family. , Thesis (MSc) -- Faculty of Science, Zoology, 1941

- Description: This introduction and ensuing essay are something in the nature of a personal confession. Deemed as such what I have written concerning Samuel Palmer has not, in any way, been written as an exercise, but rather for the purpose of self-edification. This I will elaborate upon while disclosing my motive for writing on Palmer. Palmer's works - when I first saw them - were something of a revelation. They seemed the alpha and omega of my own artistic endeavour. Perhaps the term which best describes the euphoria I felt is 1deja vu1, because although it describes a connectedness of sorts, the words have in their sound an exotic ring. There is in it an implied equivocation - and equivocality best describes my understanding of Samuel Palmer at that juncture. This euphoria I felt dimmed with the realisation that by purportedly claiming, as I was, Samuel Palmer's visionary landscapes as my goal I was treading on sacred ground; I'd arrived, as it were, in another's Paradise. The effects of this upon my own creativity were completely negative. Worse still, I lacked the necessary means to extricate myself from Palmer's paradisiacal visions. His influence was incapacitating and convoluting my own growth. It was obvious then that I had to be rid of Samuel Palmer. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 1939

- Description: The development of Soil Science in western Europe, eastern North America, and later in other countries, which, in its modern form only started about the beginning of the last century, might be said to mark the first step in the consideration of Soil Erosion from a scientific aspect, although it was some time before scientists began to concentrate on and study the problem as one which demanded a detailed investigation. Empirically, erosion has been noted and, where the value of the land warranted it, practical methods adopted for its control, in many cases with no small measure of success, for centuries, but the methods adopted were localised to small regions, and the major destruction went on unchecked. The seriousness of this destruction was usually not realised until too late, and striking examples exist of the complete desiccation resulting from this neglect. Those of China, Arabia, Mesopotamia and other countries have often been quoted, and need not be described again here. , Thesis (MSc) -- Faculty of Science, Chemistry, 1936

- Description: An estimated third of the 29 million tons of food produced annually in South Africa goes to waste (Oelofse, 2014). Fifty percent of this waste (by mass) occurs during the agricultural production and post-harvest handling and storage stages (von Bormann et al., 2017). At the same time 13 million South Africans routinely experience hunger, with malnutrition a serious concern for early childhood development (StatsSA, 2018). This disconnect between the need for food and the food that is available for consumption but being wasted, has profound social, environmental and economic impacts. This, in turn, suggests that there must be opportunities to create social, environmental and economic value through innovative and transformative initiatives that link food producers with food consumers in South Africa, particularly those in need. Food for Us is a sustainable food systems mobile phone learning pilot project initiated in 2017 by a consortium of partners in South Africa working with the United Nations (UN) Sustainable Lifestyles and Education Programme within the One Planet Network. The intention was to design and develop a mobile application (app) that could help reduce on-farm food surplus, while also supporting social learning. The initial phase of the project was 18 months. This publication shares what has been learned and can also be considered a springboard for the potential that is possible.

- Description: The child's language development is one of the most notable achievements of the preschool years. Children must develop their language skills effectively to access the curriculum. Practitioners of Early Childhood Development (ECD) have a substantial impact on children's spoken language development. As a result, three centers in the Buffalo City Education District are the subject of this dissertation's investigation into how ECD practitioners contribute to children's oral language development. The applicable theory used in the study was Vygotsky's Zone of Proximal Development (ZPD) theory. The existent phenomenon was examined using the interpretivist research paradigm and the qualitative research methodology. The study used a phenomenological research approach to examine the perspectives, functions, and experiences of individuals (ECD practitioners) in the growth of children's oral language. The study used purposive sampling. Participants were purposively selected as because of their proximity to the researcher’s workplace. The fifteen practitioners in the chosen ECD centers were interviewed in semi-structured interviews, and data were also gathered through observations. Following transcription, sorting, and categorization, the gathered data were thematically analysed using themes inferred from the study objectives. The study's conclusions showed that ECD specialists help children improve their oral language in a useful way. As a result, they require training in the creation and application of various strategies for fostering oral language in young children. Short courses will also assist practitioners in fostering the overall development of children. One of the key elements that interferes with effective teaching and learning at ECD centers, though, is a shortage of resources. , Thesis (MEd) -- Faculty of Education, 2023
