In recent years, there has been a growing trend for the use of industrial by-products in the production of blended cements because of economical, environmental, ecological and diversified product quality reasons. Granulated blast furnace slag, a by-product of the transformation of iron ore into pig-iron in a blast furnace, is one of these materials which is used as a cementitious ingredient. The aim of this study is to investigate the properties of Portland slag cement (CEMII/B-S) by using separate grinding and intergrinding of granulated blast furnace slag and Portland cement clinker. For this purpose, granulated blast furnace slag was used as mineral admixture replacing 30% of the clinker. Clinker and granulated blast furnace slag were ground to four different Blaine fineness values of 3000 cm2/g, 3500 cm2/g, 4000 cm2/g and 4500 cm2/g by intergrinding and separate grinding in a laboratory ball mill. Then, eight Portland slag cement mixes and four Portland cement control mixes were prepared, in order to determine and compare 2-, 7-, 28-, and 90-day compressive and flexural strengths, normal consistencies and setting times. It was found that for the Blaine fineness values of 3000 cm2/g, 3500 cm2/g and 4000cm2/g, the 2-, 7-, 28-, and 90-day compressive strength of the interground Portland slag cements had higher values than the separately ground Portland slag cements. However, for the Blaine fineness values of 4500 cm2/g, separately ground Portland slag cement specimens had slightly higher 2-, 7-, 28-, and 90-day compressive strength values than the interground ones.

By considering San Francisco’s legal, social, and cultural history during the late 19th and early 20th centuries in relation to American law, missionary women, and Chinese American prostitutes, this thesis argues that by aggressively trying to control Chinese sexuality through laws, “yellow slave” narratives, Christianizing, and the immigration process, the American government and missionaries created an atmosphere ripe for Chinese prostitutes in America with varying degrees of sexual freedoms.

Rethinking education in rural areas firstly requires reviewing different legislation from a historical perspective and then reconsidering the place of education in the current rural development debate. To a large extent, rural areas have been neglected in development policies and similarly, the rural dimension of basic education issues, especially in South Africa, has been largely overlooked. Basic facts and figures, as elaborated in this thesis, shed light on the need to devote more attention to rural education. In this thesis, South African legislation in relation to basic education for Black people in rural areas during the colonial period up to the democratic era was investigated. The impact of South African legislation on Black education in rural areas is difficult to unravel and solve overnight since its thinking and practice was consolidated over centuries. However, an attempt was made to determine what the policymakers, mostly White dominated governments who ascribed to segregatory and racial attitudes, did to ensure that different policies enshrined in various legislation impacted negatively on education of people predominantly residing in rural areas. The research affirmed that education of Black people in rural areas was, in most instances negatively impacted by policies of previous White governments. The apartheid government (1948-1993) used poor funding strategies to ensure that there were low teacher-pupil ratios and teacher qualifications. Unequal pattern of education spending continued well into the democratic era. This poor funding which impacted negatively on, especially rural schools, made infrastructural provision in rural areas difficult. Even though the democratic government have competitive legislative policies in place, it was concluded that educational policies since 1994 were hastily implemented and insufficient consideration has been given to the contextual realities in South African schooling, particularly in rural areas. Hence the democratic government still need to give grave attention to the issue of education in rural areas. / Educational Studies / DED (HISTORY OF EDUCATION)

A presente tese estuda o negócio fiduciário e suas potencialidades no direito brasileiro, especialmente quando associado à técnica do patrimônio separado. Embora o legislador tenha se utilizado da titularidade fiduciária elemento essencial do negócio fiduciário e da afetação patrimonial para variadas atividades, não previu modelo geral que habilitasse os particulares a entabularem ajustes fiduciários com patrimônio separado para as mais diversas finalidades. Por isso que, no Brasil, falta instituto que pudesse ser equiparado ao trust contido na Convenção de Haia sobre a Lei Aplicável aos Trusts e sobre o Reconhecimento Deles. As tentativas de incorporação de tal modelo jurídico no direito pátrio não lograram êxito até o momento e o cenário normativo brasileiro permanece fragmentado. A tese, assim, examina a conformação atual do direito pátrio em relação ao negócio fiduciário e as utilidades que adviriam da introdução da fidúcia como categoria ampla de negócio fiduciário com patrimônio separado. Nessa direção, a tese investiga (i) a admissibilidade do negócio fiduciário no direito brasileiro; (ii) a disciplina jurídica que lhe é aplicável; (iii) os efeitos da utilização da propriedade resolúvel aos negócios fiduciários, bem como da aposição das cláusulas de inalienabilidade, impenhorabilidade e incomunicabilidade; (iv) as potencialidades funcionais e limites do negócio fiduciário; (v) a disciplina jurídica do trust a que se refere a Convenção de Haia; (vi) a adoção pelo legislador da técnica da separação patrimonial conjugada com a titularidade fiduciária; (vii) a tipificação do negócio de fidúcia como aquele que possibilitaria a criação, pelos particulares, de titularidade fiduciária e patrimônio separado; (viii) o negócio de fidúcia como maneira de se incorporar os elementos essenciais do trust contido na Convenção de Haia; e (ix) a relevância da tipificação do negócio de fidúcia como meio de suprir determinadas lacunas do direito brasileiro / This thesis studies fiduciary contracts and their potentials in Brazilian law, especially when they are associated with the technique of separate estate. Although Brazilian law already deploys fiduciary ownership an essential element of the fiduciary contract and separate estate as a mean to regulate many activities, it does not lay down a legal model enabling people to use these techniques for general purposes. Therefore, still lacks in Brazil a legal framework similar to the trust as described by The Hague Convention on the Law Applicable to Trusts and on their Recognition. Attempts to incorporate this legal model in Brazilian law have not been successful so far; therefore, Brazilian legal framework remains fragmented. In this context, the thesis examines the current regulation of the fiduciary contract in Brazilian Law, and the benefits that would result from the introduction of fiducia, understood as a comprehensive legal model combining the techniques of fiduciary contract and separate estate. To this end, the thesis investigates (i) the admissibility of fiduciary contracts in Brazilian law; (ii) the rules applicable to it; (iii) the stipulation of resoluble ownership in fiduciary contracts and the stipulation in these contracts of inalienability, unseazability and incommunicability clauses; (iv) the potentials and limitations of fiduciary contracts in Brazilian law; (v) the legal regulation of trusts as they are described by the Hague Convention; (vi) the use by Brazilian legislator of the legal technique of separate estate combined with fiduciary ownership; (vii) the adoption by Brazilian law of fudicia as the type of contract that will enable people to use the techniques of fiduciary ownership and separate estate; (viii) fiducia as a mean to incorporate in Brazilian law the essential elements of the trust described by the Hague Convention; and (ix) the importance of fiducia as a mean to fill in several gaps of the Brazilian law.

The separate sphere ideology, dominant but never hegemonic in Victorian Britain, dictated that women’s natural vocation was to be wives and mothers. Between the years 1850 to 1901, the surplus woman problem and a nascent feminist movement challenged the separate sphere ideology. It was also reinforced by imperialist ideologies that held the British family as a sign of Britain’s superiority, and eugenics which placed great importance on heterosexual marriage and reproduction. How did novelists, especially women novelists, respond to the challenges against the separate sphere ideology? How did they depict unconventional women such as surplus women, women who behaved in transgressive ways, feminist women, lesbians, and women who were in interracial relationships? The conventional narrative stressed the importance of marriage, and unconventional characters either reformed themselves or met tragic fates. This remained consistent throughout the second half of the 19th century. At mid-century, unconventional women were the ones who rejected marriage, had an affair, etc. As women began to gain rights in education, work, and civic rights, the temptations that drew middle class women away from conventional life shifted to wanting to work or becoming feminists. Novels also depicted alien others, such as lesbians and non-white people, as menaces and threats to conventional marriage. Acceptable unconventionalities were limited: it was acceptable for women to be unconventional if they were exceptional or they broke one convention but upheld another, such as motherhood. At the end of the century, New Women novelists and other novelists that sympathetically depicted unconventional women critiqued the separate sphere ideology, but were overwhelmingly pessimistic about the possibility that women could escape convention.

The Master’s Thesis aims to laboratory test the possibilities of utilization mica separate, which arises during the process of floating kaolin as a by-product together with sand. Mica and sand are then separated by flotation or vibration. The mica separate thus formed was subjected to analysis. XRD and heating microscopy methods were used for analysis. Subsequently, experiments with mica separation as a filler in composites based on epoxy resins were set up and performed. Furthermore, the separate was tested as a part of plasters and visual building elements. Last but not least, the separate was mixed into the ceramic, which was then subjected to firing in the selected mode. The diploma thesis provides a comprehensive overview of the above-mentioned possibilities of using mica separation, which is based on a sufficient amount of experimental data.

Magister Artium - MA / The way in which people utilise their FREE TIME [that is time left after all commitments (social and physiological) have been met] forms the central theme of this study. An important aspect of this theme for the geographer is the interaction between supply and demand of recreational facilities, because determines the spatial location of facilities in urban areas. In the South African society certain factors which influence the normal interaction between supply and demand have developed which can be identified as problems. In this study the problems which exist regarding recreation and the use of free time are examined with specific reference to the people living in Bellville South, a "Coloured" Group Area on the Cape Flats. Data for the study was collected with the air of a structured questionnaire and thereafter statistically analysed with the intention of answering the following questions: What is the nature and extent of the use of free time during the day, over weekends and during vacations of the inhabitants of Bellville South? How does the politico-economic structure influence the supply of facilities for recreation in Bellville South? What is the influence of the politico-economic structure on the demand for facilities (the recreational behaviour) for the inhabitants of Bellville South? The data which had been collected with the aid of questionnaire, was further supplemented with personal interviews. In order to answer the above questions satisfactorily, recreation resource base in Bellville South was looked firstly. The local supply was measured according to national and international norms based on information obtained from the relevant literature. An attempt was made secondly to determine the demand for recreation generated by the community. It was evident from the literature that the socio-economic level of communities played a vital role in the determination of the extent of their demand. By examining certain socio-economic parameters, it was found that the community of Bellville South consisted mostly of people from the working-class. Subsequently the factors which have an influence on the recreational behaviour of the respondents during the day, weekend and vacation time-periods, were examined. It was found that, as one can expect from a predominantly working class community, recreation was mostly directed at the home environment during all three time-periods. This can be explained by referring to the constitutional constraints (Group Areas Act, Separate Amenities Act), socio-economic constraints and the inadequate recreational facilities in the study area. The interaction between demand and supply within the prevailing politico-economic structures was subsequently examined. The correlation between demographic and socio-economic variables and recreational activities was examined with the aid of crosstabulations. The resulting spatial pattern of the recreational behaviour of the respondents was analysed cartographically. By examining the latent and potential demand for recreational facilities it was found that there are very real needs in the study area. Lastly, recommendations were made with a view of alleviating the problems which have been identified. It was felt that immediate attention should be paid to shortcomings in the supply and maintenance of recreational facilities in Bellville South, while the political problems which make a meaningful utilisation of recreational facilities by everybody in South Africa impossible at the moment, should also be removed.
