Internationalisation of business clusters: the case of fruit processing clusters in Ghana
Since Alfred Marshall propounded industrial clusters, the study of spatial organisation over the years has revealed numerous benefits of agglomeration to businesses, countries and regions. Until recently, discussions on the gains associated with internationalising clusters have mainly been situated …

Cancer Related Symptom Clusters
… of psychological and physical symptom clusters are increasing, yet they are under-reported and under treated. The current study, informed by the Theory of Unpleasant Symptoms, explores a large sample with a diverse representation of cancer diagnoses, examining the relationship between …

Masses of globular clusters
… dispersions have been derived for 10 globular clusters from high dispersion (6.7A mm-1) coude spectra of the integrated light. Two methods were used. The first involved the comparison of the cluster spectra with star spectra convolved with an appropriate velocity distribution function. This is …

Old southern open clusters
… years spent in the investigation of old open clusters at the SAAO. Each chapter is a preprint of a paper which has been submitted or accepted for publication and is therefore an independent entity with its own list of acknowledgements and references. Since each chapter is intelligible without …

Polygons, stars, and clusters
One technique for displaying a set of quantitative variables is to represent the set as a polygon. Such displays allow the observer to visualize complex information quickly, as a whole. Polygon displays have been employed to display information for analysis, status, or presentation. An experimental …

Importance of Self-Interaction Correction in Hydrogen-Bonded Water Clusters and Water-Ion Clusters
… complexes and interaction of ions with water clusters. The strongly constrained and appropriately normed (SCAN) density functional approximation (DFA) has been found to give the correct energy ordering of low-lying isomers of water hexamers, resolves the density anomaly between water and ice, …

Cosmology with clusters of galaxies : high-redshift clusters and the evolution of cluster substructure
Clusters of galaxies have become an important cosmological tool, yet we do not un-erstand many aspects of their formation and development. In this thesis, I pursue two projects aimed at using clusters to constrain cosmology and better understanding cluster evolution. First, I examine the Chandra …

Fragmentation of Charged Binary Clusters
Fragmentation of binary mesoscopic clusters composed of H2O/CH3OH and charged with ions (Na+, K+, Cs+,F^, Cl-, I-) of similar sign are studied by molecular simulation. The fragmentation involves the departure of a cluster containing one or more ions from the parent droplet by a break-down of the …

Metalloid aluminum clusters with fluorine
… interest in using molecular-scale metalloid clusters as a way to achieve very rapid rates of metal combustion. These clusters contain a mixture of low-valence metals as well as organic ligands. Here we investigate a prototypical aluminum metalloid cluster to determine system stability if the …

Evolution of Galaxies in Clusters
In dieser Doktorarbeit studiere ich die Entstehung und Entwicklung von Galaxien in Galaxienhaufen sowohl theoretisch als auch unter Einbeziehung von Beobachtungsdaten. Diese Doktorarbeit gliedert sich in zwei Teile: Einem theoretischen Teil schliesst sich eine Datenanalyse an. Im ersten Kapitel …

New high nuclearity carbonyl clusters
… of a series of new Rhodium and Au-Fe carbonyl clusters. Most new high-nuclearity rhodium carbonyl clusters have been obtained by redox condensation of preformed rhodium clusters reacting with a species in a different oxidation state generated in situ by mild oxidation. In particular the …
