Causes and possible consequences of hybridisation in angelfishes at Christmas Island
… of reef fishes, with 26 species implicated in hybridisation. However, very little is known about hybridisation in angelfish, especially in terms of fitness of the hybrids and possible ecological consequences. Hybrids between three species (C. flavissima, C. eibli and C. vroliki) in the genus …

Shaping a “Glocal” Premier League in Distinct Markets: Localisation and Hybridisation
The modern English Premier League (EPL) has become an institution with global reach. EPL has achieved substantive global success since its inception in 1992, bringing significant revenue from overseas markets. Given EPL’s worldwide market footprint, this dissertation focuses on the processes of …

Optimisation of interphase fluorescence in situ hybridisation for detection of common aneuploidies
… colours. The steps of denaturation, hybridisation and detection are the same as those used in a uni-colour FISH experiment. The results obtained from hybridisation of an unselected series of 20 uncultured lymphocytes and 27 uncultured amniocytes indicate that the technique is reliable …

The influence of fiber hybridisation on dynamic mechanical behavior of natural based composites
The relatively higher costs of synthetic fibres (glass, carbon, kevlar fibre) used in fibre reinforced composite materials make it desirable to investigate natural fibres as a source of possible reinforcement in low-cost applications. Natural fibres are abundant and represent a significant cost …

Harakeke fibre as reinforcement in epoxy matrix composites and its hybridisation with hemp fibre
… in polymer composites and to assess the hybridisation of harakeke/hemp hybrid composites. Both short and long fibres were used as reinforcement, while a low viscosity epoxy resin was used as the matrix. Short fibres were alkali treated before being used to reinforce epoxy, while long …

Genetic diversity and hybridisation estimates of Arctocephalus tropicalis and A. gazella from Marion Island
In this study, hypervariable region I (HVRI) of the mitochondrial DNA (mtDNA) control region, and five microsatellite loci were used to assess genetic variability and the extent of hybridization between the two fur seals (Arctocephalus tropicalis and A. gazella), that occur on Sub-Antarctic Marion …

Mechanisms and consequences of hybridisation between Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
… trout, S. trutta, to investigate mechanisms of hybridisation through sperm-egg interactions, much of which is poorly understood. Salmon and trout experience conspecific sperm precedence during in vitro sperm competition experiments, when sperm volumes and release times are equalised. This thesis …

Hybridisation of dental hard tissues with modified adhesive systems: therapeutic impact of bioactive silicate compounds on bonding to dentine
… as well as adhesion testing, about dentine hybridisation and about the drawbacks of contemporary bonding systems. Several studies revealed excellent immediate and short-term bonding effectiveness of etch-and-rinse adhesives, yet substantial reductions in resin- dentine bond strength occur …

The added value of BAP1 immunohistochemistry and fluorescence in situ hybridisation for CDKN2A/p16 and NF2 in the diagnosis and prognostication of pleural mesothelioma
… inhibitor 2A gene (CDKN2A) fluorescence in situ hybridisation investigations (FISH) were performed. Two patients whose cases highlighted the importance of molecular based analysis were selected and further explored in the form of two case reports. The final retrospective study involved the …

Nanoparticle sensors for the detection of DNA related to disease
… the stability of the conjugates and their hybridisation efficacy was investigated. It was discovered that the thioctic acidmodified oligonucleotide-nanoparticle conjugates remain stable under these conditions for a substantial period of time compared to thiol-modified oligonucleotide …

Modified oligonucleotides for the functionalisation of nanoscale materials
… of a nanostructured surface for the detection of hybridisation events by surface enhanced resonance Raman scattering (SERRS). Thioctic acid was considered a suitable linker group with which to tether oligonucleotides to nanoparticle substrates. As such, routes to the modification of …

The search for hybrid tectonics in contemporary African architecture: encounters between the global and the local
… that there is an emerging phenomenon of tectonic hybridisation in contemporary architecture in Africa where global and local ways of making are being combined. A growing awareness of this tendency was informed by an extended period of practicing, teaching, and re - searching architectural …

An evidence-based policy for the provision of subsidised fertility treatment in California: Integration of array comparative genomic hybridisation with IVF and mandatory single embryo transfer to lower multiple gestation and preterm birth rates
… of embryos with array comparative genomic hybridisation (aCGH). This investigation considers the interconnected problems of preterm birth and multiple gestation in a demographic context, showing that although the contribution made by conventional IVF to these adverse outcomes in California …

Urban hybridity: an alternative development strategy for Woodstock
… concept lay in understanding the influence of hybridisation on contemporary urban society and how this, in turn, affects and changes places within the city. I find this subject interesting as I personally feel influenced by the hybridisation of global and local conditions. As technology …

Hybrid governance in the global south: A case study of collusion within the South African construction industry
… of hybrid governance. To analyse the process of hybridisation I draw on the concepts of corruption, authority and governmentality as lenses through which to analyse the rationalities, strategies and practices used in the enactment of authority. The research findings reveal that the process of …

A study of some co-ordination compounds formed between nickel diammines and the nitrite ion
Pauling (1931) introduced the concept of the hybridisation of (n - 1)d, ns and np orbitals to explain the two classes 'ionic' and 'covalent' into which co-ordination compounds of transition metals appeared to fall. These two classes in general have different numbers of unpaired spins, hence they …

Rapid diversification and wing colour pattern evolution in tropical butterflies
… phylogeographic relationships and patterns of hybridisation in three ithomiine genera: Melinaea (chapter 2), Mechanitis (chapter 2) and Ithomia (chapter 5). I also study the genetic architecture underlying wing pattern divergence in these genera (chapter 3-5) and in Heliconius (chapter 4), to …

Study of virulence factors of Staphylococcus aureus
… mutagenesis (STM) uses comparative hybridisation to isolate mutants unable to survive specified environmental conditions and has been used to identify genes critical for survival in the host. Both methods have been used to identify virulence genes in S. aureus. The main aim of this …
