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 ...
The economics of climate change adaptation strategies in the Ceres Region, Western Cape
(University of the Free State, 2013-07)
The Western Cape (WC) region of South Africa, with its Mediterranean-type climate and predominantly winter rainfall, has been identified as highly vulnerable to projected climate change within both global and national ...
Red emission of Praseodymium ions (Pr ³⁺)
(University of the Free State, 2011-11)
English: Red glowing phosphors were prepared by adding Pr3+ ions as activators to several oxide host matrixes; CaTiO3, LaTaO4, YTaO4, and GdTaO4. The perovskite CaTiO3:Pr3+ compound is a phosphor that glows with a single ...
Synthesis, electrochemistry and density functional theory calculations on chrome and cobalt carbene and betadiketonato complexes
(University of the Free State, 2014)
English: Two series of metal(β-diketonato)3 complexes were synthesized: tris(β-diketonato)chromium(III) complexes (where β-diketonato = [R1COCHCOR2]- = acac, ba, dbm, tfba, tfth, tffu, tfaa, hfaa) and tris(β-diketonato)cobalt(III) ...
Analysis of zirconium containing materials using multiple digestion and spectrometric techniques
(University of the Free State, 2014-10)
English: The preparation of pure zirconium metal for nuclear applications is difficult due to the
non-reactivity of zirconium minerals, such as zircon. The ability to accurately analyse
zirconium-containing materials ...
Preparation, characterisation and selective hydrocarbon transformation applications of flatmodel and zeolite-supported platinum catalysts
(University of the Free State, 2014-10)
English: Allyl, amino and silanol (Si-OH) functionalised silicon wafers with epitaxial layer of SiO2
(SiO2/Si-wafers) were used as two-dimentional supports to prepare flat model Pt/SiO2/Si-wafer catalysts by
spin coating ...

(University of the Free State, 2006-05)
The study was conducted in the Somali region of eastern Ethiopia, with an arid to semiarid climate. The study aimed at the characterization of the rangeland resources, assessing the current condition of the rangeland, ...
Identification and expression analysis of flavonoid biosynthetic genes in the genus Clivia
(University of the Free State, 2010)
English: Anthocyanins belong to a large group of secondary plant metabolites, the flavonoids, and fulfil a range of biological functions that include the cyanic pigmentation they provide to flowers, fruits, vegetables and ...
Mixogram parameters and their relationship to bread wheat quality characteristics
(University of the Free State, 2010-11)
English: The main objective of this research was to determine relationships between selected mixogram parameters and grain, milling, rheological, baking qualityrelated and baking quality characteristics to assist wheat ...
