'n Ondersoek van alkynmetatese deur middel van molekuulmodellering en laboratoriumeksperimentering
(North-West University, 2004)
In this study, the metathesis reaction of alkynes was investigated with the classic
Mo(CO)6/PhOH-catalyst system by utilizing both laboratory experimentation and molecular modelling. The reaction was optimized by using ...
Data dependent choice of the tuning parameter for the modified bootstrap
(North-West University, 2004)
It is the purpose of this study to investigate a procedure for estimating the tuning parameter, m, in the modified bootstrap (also known as the m-out-of-n bootstrap, the moon bootstrap or the m/n bootstrap). The procedure ...
Optimization of network mesh topologies and link capacities for congestion relief
(North-West University, 2004)
Network design problems usually include the selection of nodes and arcs from lists of
potential sets to accomplish certain desirable properties. Foremost is often the capability
to accommodate the flow demands at a ...
Effects of termination shock acceleration on cosmic rays in the heliosphere
(North-West University, 2004)
The interest in the role of the solar wind termination shock (TS) and heliosheath in cosmic ray (CR) modulation studies has increased sigm6cantly as the Voyager 1 and 2 spacecraft approach the estimated position of the TS. ...
Synthesis and modeling of alicyclic organic ligands
(North-West University, 2004)
The study of alicyclic cage molecules has in recent years increased due to the possibilities in application of these compounds. The photocyclization of the endo conformation Diels-Alder adduct of p-benzoquinone and ...
A systematic revision of Drimiopsis Lindl. & Paxt. (Hyacinthaceae)
(North-West University, 2004)
Drimiopsis Lindl. & Paxt. is one of many genera within the Hyacinthaceae that have
not been comprehensively reviewed. In this study, a comprehensive systematic
revision of Drimiopsis is accomplished through examination ...
A guideline document for the application of an appropriate EMS for greener governance within DWAF
(North-West University, 2004)
The purpose of this study is to establish whether an environmental management
system will be beneficial for the Department of Water Affairs and Forestry
(DWAF) as a tool by which to apply "greener governance•, and if so, ...
Evaluation of fluidised-bed reactors for the biological treatment of synthol reaction water, a high-strength COD petrochemical effluent
(North-West University, 2004)
Reaction water, a high-strength COD (chemical oxygen demand) petrochemical effluent, is generated during the Fischer-Tropsch reaction in the SASOL Synthol process at SASOL SynFuels, Secunda, South Africa. Distillation of ...
The application of diatom-based pollution indices in the Vaal catchment
(North-West University, 2004)
South Africa is a semi arid country and the provision of water clean water to a steadily
growing population is currently one of the major challenges facing governmental
organisations. Water resources in South Africa are ...
Comparison of complete mitochondrial genome sequence between different ethnic groups from Southern Africa
(North-West University, 2004)
The human mitochondrial genome is a 16,569 base pair double-stranded deoxyribonucleic acid (DNA) molecule located in the mitochondrion. The mitochondria1 genome sequence is
conserved, maternally inherited and undergoes ...
