A differential scanning calorimetric study of the interaction of zinc benzothiazole-2-thiolate, sulfur, stearic acid, and zinc stearate in the absence and presence of polyisoprene

Abstract: The interactions between mixtures of zinc benzothiazole-2-thiolate (ZMBT), sulfur, stearic acid, and zinc stearate were studied by DSC in the absence and presence of polyisoprene (IR). It was established that ZMBT reacts with stearic acid to form zinc stearate and 2-mercaptobenzothiazole (MBT). In the presence of stearate compounds, MBT is readily available from the start of vulcanization, whereas it becomes only slowly available in the absence of these compounds. The effectiveness of the vulcanization process increases for the systems IR/ZMBT/sulfur < IR/ZMBT/sulfur/stearic acid < IR/ZMBT/sulfur/zinc stearate. In view of the above results, interaction mechanisms are proposed for the different systems. © 1993 John Wiley & Sons, Inc.

The Informal Sector in Selected Residential Area of Port Elizabeth

Abstract: The Employment Research Unit undertook three surveys on the informal sector during 1985 and 1986, two among Blacks and one among Coloureds. The aim of the surveys was to establish the composition and nature of the sector in the Port Elizabeth/Uitenhage area. It was found that in both these sectors most of the respondents were involved in trading and that very few were involved in manufacturing. Incomes earned by most of the respondents were low. and compared to subsistence level incomes only, It also appeared that the employment creation spin‐off was low. Similar problems inhibited the growth and development of this sector for both Blacks and Coloureds. They were: short‐ and long‐term loans, accommodation, poor infrastructure, and legal restrictions.

Chiliasm: an escape from the present into an extra–biblical apocalyptic imagination

Abstract: The purpose of this paper is to give an overview of the origin, history and philosophy of chiliasm/millennialism. The origin of this concept is ascribed to an erroneous interpretation of Jewish apocalyptic imaginary. Christianity is shown to have been influenced via Judaism. Currently three versions of the concept are observed, namely premillennialism, amillennialism and postmillennialism. The conclusion arrived at is that chiliasm/millennialism is an escape from the present into extra-biblical apocalyptic imagination. Chiliasm does not fully appreciate the historical character of the Bible.
