Synthesis and characterisation of a selection of phthalocyanines covalently bonded to water-soluble polymers and a ferrocenyl fragment
(University of the Free State, 1998-06)
English: This thesis is concerned with the synthesis of phthalocyanine derivatives and their anchoring onto
water-soluble polyaspartamides to produce compounds that may have biomedical applications,
especially in the ...
Chemical kinetics, electrochemistry and structural aspects of ferrocene-containing b-diketonato complexes of rhodium(I) and iridium(I)
(University of the Free State, 1999)
English: Synthetic routes to prepare new Rh(I)-β-diketonate complexes [Rh(FcCOCHCOR)(CO)2] and [Rh(FcCOCHCOR)(CO)(PPh3)] with Fc = ferrocenyl and R = Fc, C6H5, CH3 and CF3 have been developed and optimized. Optimized ...
The genus Cheiracanthium (Araneae: Clubionidae) in southern Africa
(University of the Free State, 1995-11)
English: The southern African representatives of Cheiracanthium C.L. Koch, 1839 are revised after examining 617 adult specimens. Eight species of Cheiracanthium are recognized from this region, four are new (C. dippenaarae, ...
The development of a virtual reality simulator for certain gastrointestinal endoscopic procedures
(University of the Free State, 1999-05)
English: A Virtual Reality Gastrointestinal Trainer/Simulator has been developed to enable the
simulation of gastrointestinal procedures on a personal computer (PC). Virtual Reality
(VR) techniques are used in the ...
A system for drought monitoring and severity assessment
(University of the Free State, 1995-02)
English: The objectives of this study were:
(i) to develop a near real-time crop-specific drought
monitoring system that delimits drought stricken areas and
assesses the severity of droughts in these areas,
(ii) to ...
The expression of leaf rust resistance in wheat lines containing Lr12 and Lr13
(University of the Free State, 1995-11-30)
Monogenic resistance in wheat (Triticum aestivum L.) to leaf rust, caused by Puccinia
recondita Rob. ex. Desm. f. sp. tritici, has generally not been durable. One strategy of
attaining durable resistance to rust diseases ...
Grain yield and breadmaking quality of wheat lines with leaf rust resistance genes Lr29, Lr34, Lr35, and Lr37
(University of the Free State, 1999-06)
English: 1. The aim of this study was to determine if the leaf rust resistance genes Lr2g, Lr34,
Lr35 and Lr37 have an effect on the quality and yield characteristics of a cultivar it is
incorporated into.
2. Near-isogenic ...
The hydrolysis of linalyl acetate and α-terpinyl acetate by yeasts
(University of the Free State, 1999-06)
English: Hydrolysis of esters by means of hydrolases such as proteases (Jones and
Beck, 1976), lipases (Santiello et al., 1993) and esterases (Boland et al.,
1991) has become a well established method for the resolution ...
Transfer and adoption of technology: the case of sheep and goat farmers in Qwaqwa
(University of the Free State, 1998-12)
English: It is evident from the literature studied that very little is known about the characteristics and farm
level factors (predictors) contributing to or affecting the adoption of livestock veterinary
technologies ...
The use of different anabolic agents in gilts
(University of the Free State, 1995-07)
24 Crossbred gilts (Large White x Landrace) purchased as weaners were randomly
allocated to four treatment groups (n = 6) and submitted for an observation period of
three phases: Phase I, in which the animals were treated ...
