Text in Afrikaans / Die herscomgestelde gesin word in hierdie navorsingstudie ondersoek as 'n kompleksa alternatiewe gesinstruktuur met eiesoortige strukturele kenmerke, probleemarecs en rituele wat nie aan die norm von die kerngesin ontleen kan word nie. In die literotuuroorsig word hierdie aspekte van nader beskou en tot die gevolgtrekking gekom dot die belangrike rol van die eie ouer in die hersoomgestelde gesin grootliks misgekyk word. Die verbondenheid van die eie ouer aan beide die ouer-kind- en die nuwe egpoorsisteme mack ditvir hom/hoar moontlik om 'n sleutelrol te vervul tydens gesinsinteroksies, eenheidsvorming en die opvoedingsgebeure in die hersoamgestelde gesin. Dit is moontlik vir die eie ouer om vanuit 'n unieke posisie as 'n buffer te dien in die problemotiese stiefouer-stiefkindverhoudinge. Hierdie maontlikheid bestaon egter slegs indien die eie ouer oor voldoende kennis, insig en voardighede beskik. 'n Uitgebreide kwalitatiewe ondersoek aan die hand van semi-gestruktureerde onderhoude met die lede van ses hersaamgestelde gesinne het die volgende tendense aan die lig gebring: • Eie overs verwag van nuwe egliede om kinders in die hersaamgestelde gesin uit die staanspoor te aanvoor en lief te he. • Eie overs koester konflikterende gevoelens ten opsigte van die dissiplinering van hul kinders deur die stiefouer. • Eie ouers, sfiefouers en kinders in hersaamgestelde gesinne goon dikwels gebuk onder d\e los van onverwerkte gevoelens van verdriet en verlies. • Die hantering van finansies ten opsigte van inwonende eie en stiefkinders, asook nie-inwonende kinders en vorige egliede skep spanning en bemoeilik goeie verhoudinge. • Eie ouers is dikwels so verdeeld tussen die belange van nul kinders en die van hul nuwe moats dot hulle dit moeilik vind om in 'n tweede huwelik 'n betekenisvolle verhouding met hul nuwe lewensmaat op te bou. Genoemde tendense het 'n bepolende rol gespeel in die ontwikkeling von 'n begeleidingsprogram vir eie ouers. Agt sessies met doelwitte geboseer op hierdie probleemoreas is gestruktureer om die eie ouer met noodsaaklike kennis en vaardighede toe te rus ten opsigte van harmoniese verhoudingstigting en -onderhouding in hersaamgesfelde gesinne. Die begeleidingsprogram is deur middel van 'n fokusgroeponderhoud aan die evaluering von vier ouerpare in hersaamgestelde gesinne onde&Werp en is aon die hand van hul aanbevelings verfyn en gefinaliseer.

The global energy sector is facing a crisis caused by the increasing demand for energy. Non-renewable energy sources, such as fossil fuels produce greenhouse gases that are largely blamed for climate change. The Kyoto protocol requires industrialised nations to reduce their collective greenhouse gas emissions. Hydrogen as an alternative fuel can serve as a substitute. Hydrogen production is expensive and the gas is largely derived from fossil fuels by a process that releases large quantities of greenhouse gases. In South Africa work on hydrogen production was first done on the Hybrid Sulphur cycle. The high operating temperature and highly corrosive environment involved in the process makes this cycle difficult to work with. The copper-chloride cycle has a lower operating temperature and uses less corrosive materials, making the cycle potentially more economical. Evaluation of the cycle started with the development of four models: the Base model, the Canadian model (developed in Canada) the Kemp model and the Excess model. The Kemp model has the best overall efficiency of 40.89 %, producing hydrogen at a cost of US$4.48/kg. The model does not however provide the excess steam required for the cycle. The Excess model which is based on the Kemp model does provide the excess steam and produces an overall efficiency of 39 % and hydrogen at a cost of US$4.60/kg. The copper-chloride cycle has an improved efficiency and produces hydrogen at a lower cost when compared to the hybrid sulphur cycle. The final conclusion of this thesis is that the copper-chloride cycle should be investigated further and an expected capital and operational costs estimate should be developed to obtain more accurate figures. / Thesis (M.Ing.
