Description: The earliest reference to investigations of "black spot" in pineapples is made by Tryon (1898), who refers to the work of Dr A. A. Brown (1896) of the stock Branch, Victoria (Aus.), who sectioned diseased areas of pineapples and found fungal spores and hyphae in the tissues. The symptoms of this socalled "fruitlet core rot," are described by Tryon as: "well defined dark brown markings immediately beneath the surface, and passing inwards to a depth of 1/4" to 1/2"- the malady commencing in separate fruitlets, the central core of the fruit remaining quite healthy." (This description agrees with the symptoms referred to as "black spot" 1n this country). Subsequent culture of the spores (found by Brown) on slices of healthy fruit resulted in growth of Mucor racemosus. Brown regarded an invasion by this fungus as a primary cause of the disease.

Description: Parrot fishes are so abundant in the tropical parts of the Western Indian Ocean as to be of considerable economic significance. The majority are taken in traps and nets, some by spearing, fewer on lines. The flesh of even the largest is delicate and tasty, mostly eaten fresh as it is not easily preserved. It is esteemed by almost all races and classes, excepting only the Portuguese of Mozambique who do not regard these gaudy fishes with favour. In British territories, however, they are eagerly sought by the Whites. It has been stated that in some parts Parrot fishes are toxic, but as far as could be ascertained no species are ever unwholesome in East Africa or north of Madagascar to Seychelles. It is only in certain specific cases that laymen and even the native fishermen are able to distinguish individual species of Parrot fishes. Most species are more or less lumped together as “Parrots” with prefixes such as “Green” or “Red.” To the native fishermen they are known as follows: Red Sea to Suez, “Harid”; Somaliland, “Jello” or “Ponno”; Kenya to North Mozambique, “Pono”; Seychelles and vicinity, “KAKATOI”; Mauritius, “KAKATOI” or “GATEAU,” some species characterised more closely by descriptive adjectives. These fishes are commonly subject to what appears to be a parasitic infection of the nostrils, resulting in considerable swelling of the snout. , Rhodes University Libraries (Digitisation) , The main funds were provided by the South African Council for Scientific and Industrial Research, enabling expeditions to be made to Mozambique, Tanganyika, Zanzibar, Pemba, Kenya, Seychelles and the other islands north of Madagascar, whose authorities provided valuable aid and facilities in support. It had been intended to include French territories but this was unfortunately not possible. This publication and its ample colour illustration have been made possible by a generous special grant from the South African Council for Scientific and Industrial Research.

The voluntary welfare organisations of the Border and Transkei: a contribution to the sociology of social work

- Bettison, D G

Authors: Bettison, D G
Date: 1956
Subjects: Social service -- South Africa -- Transkei Social service -- South Africa -- Eastern Cape Volunteer workers in social service
Language: English
Type: Thesis , Doctoral , PhD
Identifier: vital:3314 , http://hdl.handle.net/10962/d1003102
Description: This research is intended to examine the internal organisational structure of the existing [voluntary welfare] organisations to ascertain what relationship may prove effective between themselves and the [Border Local Welfare] Board. This aim introduced the need to ascertain whether a) the organisations in any town were connected with organisations in other towns or to a central administrative office either in the area of investigation or outside it; or b) the organisations of any town were simply ad hoc units unrelated to any other organisation or similar organisations elsewhere. If the latter were the case then the difficulty of co-ordination and representation on the Board could probably be no better arranged than an ad hoc system as at present. If, however, the former was the predominant pattern, then it would suggest other and more convenient means to the end in view. Fourthly, it was hoped to gain some knowledge of the fund raising methods of welfare organisations, the nature of the people controlling them, the attitudes of managing committees to social work, and what they thought a case work agency should do; and, lastly, some indication of the history of social work as practised by the voluntary agencies in the area of investigation. These latter topics were not intended to form the principal subject matter of the work. They have not been treated fully in the text, but the information gathered has been included in appropriate places throughout.

A critical study of methods for the determination of zinc in soils and plant materials

- Eve, Desmond John

Date: 1955
Subjects: Soils -- Zinc content , Soils -- Analysis , Plants -- Analysis
Language: English
Type: Thesis , Masters , MSc
Identifier: vital:4468 , http://hdl.handle.net/10962/d1011770 , Soils -- Zinc content , Soils -- Analysis , Plants -- Analysis
Description: Although it is only fairly recently that the importance of trace elements in plant nutrition has been established, enormous advances have been made in this field of research and numerous publications of considerable scientific and economic importance, dealing with the subject, have appeared. The physiological functions of zinc in promoting plant growth have not all been satisfactorily identified as yet. There are indications, however, that zinc acts as a catalyst or regulator in plant metabolism. It appears too, that the element plays some role in chlorophyll formation. Zinc deficiency is associated with leaf chlorosis and a general collapse of v ital processes. The analysis of leaves and soils has become an essential part of the study of the nutritional diseases of plants and it is imperative that accurate and reliable methods of analysis should be available.

Description: [From Introduction]. It is the purpose of this thesis to examine some of the broad relationships which exist between different land use types and farming practises on the one hand and the geographical environment on the other. The enquiry is confined to the study of a number of farm units which have been selected within the area enclosed by the District of Albany and Bathurst situated in the south-East coastal belt of the Cape Province. The procedure adapted conforms broadly to that of a project carried out in South America by R.S. Platt of the University of Chicago and embodied in hls book "Latin America, Countryside and United Regions." Platt's project, he notes, consists of a collection of "small field studies in a frame of complex generalisations." It does not aim to give a complete geographical account of the regions he selected for investigation, but is an attempt to enlarge geograpical understanding of the respective areas.

Description: In searching for information concerning the chain of stations that William Shaw established from the Eastern Frontier of the Cape Colony towards Natal, I found that I had to consult many books. Many sources of information have recently come to light and this had to be analysed as well. In this work much had to be included that did not directly refer to Mount Coke, but it is relevant in that it affected the history of the Mission, and the effect of the Mission on the community as a whole. When histories of all the stations are written the incidents should show up in the right perspective.

Description: In the course cf the last fifteen years the general lnsect ecology of citrus orchards in the Eastern Cape has provided the subject matter of four theses presented for the degree of M.Sc. of Rhodes University. The false codlin moth, Argyroploce leucotreta Meyr., formed the subject of a thesis by Horne in 1939. Then in 1941 the same insect formed the subject matter of a thesis by Harris. The general ecology of a citrus orchard, with special regard to the biological control of citrus red scale, Aonidiella aurantii Mask., was the subject matter of Whitehead's thesis in 1948. This was a much more general investigation than the preceding two theses, and touched on many more aspects of citrus ecology. Another thesis dealing with more general citrus ecology was that of Smithers in 1953.

Description: In this thesis I have given an account of the work carried out by me on the measurement of the spectra and decay times of a few selected organic phosphors under ultraviolet and ionising radiation. The purpose of the investigation has been to attempt to throw more light on the mechanism by which energy migrates within the crystalline lattice. A general introduction is given to the process of fluorescence and the various proposed theories by which the excitation energy, which eventually appears as fluorescence light, is able to move about in the crystalline lattice.

Description: [Introduction, p. 3] The solubilities of the silver halides cannot be determined by the conventional methods of analytical chemistry because they are too sparingly soluble (of the order 1 x 10⁻⁵ to 1 x 10⁻⁶ g . equiv./1. at 25°C.) However, electrical, and to a lesser extent optical methods, are admirably suited because of their greater sensitivity. The conductometric and potentiometric methods are the two most important electrical techniques for the measurement of the solubilities of sparingly soluble salts, and are the ones employed in this research. There are large discrepancies between the published values for the solubility of silver chloride. Results obtained by the conductometric and potentiometric methods disagree. In addition, figures quoted by independent authors using the same method differ by as much as 15%.
