Inclusion compounds of multipedal hosts
… selected inclusion compounds and the a-phases of hosts 1 and 3 are presented. The hydrogen bonding patterns and host-guest interactions are analysed. The packing motif of the host compounds and host conformation within each structure is also discussed. The thermal decomposition behaviour of these …

Exogenous donor-derived hepatogenesis in chimeric hosts
… for generating donor-derived organs in chimeric hosts. In this dissertation, we begin with a comprehensive review of the literature (Chapter I) regarding histology and anatomy of liver, cardinal functions of the liver, followed by an overview of the current knowledge of embryonic liver …

Calixarene and coordination complex hosts for anions.
… based on ‘calixarene and coordination complex hosts for anion’. The research is to make synthetic chloride ion channels for possible treatment of cystic fibrosis. Our approach is based on derivatives of larger calix[n]arenes. Calixarenes are chalice-shaped molecules that form readily under base …

Clathration by diol hosts : thermodynamics and structure
… the inclusion compounds and of the a-phases of Hosts 2 and 5 were elucidated using single crystal X-ray diffraction methods. Thermal decomposition studies using thermogravimetry and differential scanning calorimetry (DSC) were carried out in order to relate the strength of the host-guest …

Interacting populations : hosts and pathogens, prey and predators
… it only for food, whereas parasites use their hosts both as their habitat and their food. I am particularly interested in microbial parasites (including bacteria, fungi, viri, and some protozoans) since they cause many infectious diseases. This thesis considers two different points in the …

The perception of Australian hosts by Japanese tourists
… on the effect of tourists' presence on hosts' communities (economic, social, environmental impacts). Only a few studies have been concerned with the influence of hosts' communities on tourists, particularly in shaping tourists' reactions to hosts' communities and the destination visited. …

Binding and Detection of Anions Using Tripodal Hosts
The aim of this project was to investigate the anion-binding properties of a range of different receptor compounds. For the most part, the receptors reported here were tripodal in nature, wherein three hydrogen-bonding receptor groups, including amines, amides and ureas, are linked around a common …

Design of multi-homing architecture for mobile hosts
… a mechanism is introduced to allow legacy hosts to communicate with MNS-MIP6 MNs and gain the benefits of reliability, load sharing and seamless handover. The mechanism involves introducing middle boxes in CN’s network. These boxes are called Proxy-MNS boxes. Context is established between …

Identifying floral hosts of cerambycid beetles using palynology
Pollen is an important food source for many insects including the adults of beetles whose larvae are important forest pests. I quantified the distribution of pollen-feeding in adults of several species of long-horned beetles (Coleoptera: Cerambycidae). Palynivory by cerambycid beetles is common in …

Coevolution between brood-parasitic honeyguides and their hosts
… world around us. Avian brood parasites and their hosts are now model systems for studying such coevolutionary interactions between species, providing striking examples of the adaptations that arise when the life histories of two species become entangled. In this thesis I highlight the adaptations …

Distributed IP mobility management for hosts and networks
… for individual mobile nodes (i.e., mobile hosts) during mobility events. DM-RMG also implements a mechanism to optimize the handover delay. The results obtained from analytical modelling and simulation show that the DM-RMG scheme outperforms the centralized mobility management schemes, as …

Mechanisms of Emerging RNA Virus Adaptation to Hosts
… by which emerging RNA viruses adapt to hosts can inform public health strategies targeting the appropriate vectors and reservoirs of the virus or the design of effective therapeutics. Therefore, we sought to identify the viral genetic determinants of host adaptation of two contrasting …

Interactions between calanoid copepod hosts and their associated microbiota
Copepods are highly abundant environmental reservoirs of many bacterial pathogens. This thesis investigates whether copepod physiology influences the abundance and community structure of its microbiome. To this end, we first examined the ability of the oceanic copepod Calanus finmarchicus to …

Monitoring security of enterprise hosts via DNS data analysis
… mirror TCP/UDP flows (between internal hosts and malware servers) pertinent to DGA queries for diagnosis by the trained models. We deploy our system in the field and evaluate its performance to show that it flags more than 2000 internal assets as potentially infected, generating more …

Nanoporous hosts for the encapsulation of conductive nanostructured materials
… conductive nanostructures in ordered mesoporous hosts is exemplified with several distinct cases by developing new synthetic methods for selective confinement of the guest structures. Namely, carbon filaments and nanotubes, metal nanowires and nanoarrays, and semiconducting nanoparticles and …
