The Physical Chemistry of pMDI Formulations Derived from Hydrofluoroalkane Propellants. A Study of the Physical Behaviour of Poorly Soluble Active Pharmaceutical Ingredients; Bespoke Analytical Method Development Leading to Novel Formulation Approaches for Product Development.
… reduction in oropharyngeal deposition. The physical properties of HFA propellants are however poorly understood and their capacity for solubilising inhaled pharmaceutical products (IPPs) and excipients used historically in CFCs differ significantly. There is therefore a drive to establish …

Exploring the relationship between patterns of physical activity, sedentary behaviour and cardiometabolic health in middle-aged Irish adults
Background and Study Rationale Being physically active is a major contributor to both physical and mental health. More specifically, being physically active lowers risk of coronary heart disease, high blood pressure, stroke, metabolic syndrome (MetS), diabetes, certain cancers and depression, and …

Functional and patient outcomes following Total Knee Arthroplasty : a multiple-methods approach
… individuals’ experiences? Do they improve their physical behaviour?Methods: A multiple-methods approach was used to attain the research objectives, using different philosophical traditions (paradigms) to improve the accuracy of the findings and gain a complete picture of outcomes. It provided an …

Finite element method using vector finite elements applied to eddy current problems
… Electromagnetic vector fields possess different physical behaviour patterns and different properties in comparison to the other vector fields and therein lies the necessity of the development of a finite element which would be able to cater for these differences . The vector finite element was …

WDM of solitons in dispersion managed transmission systems
This thesis investigates the physical behaviour of solitons in wavelength division multiplexed (WDM) systems with dispersion management in a wide range of dispersion regimes. Background material is presented to show how solitons propagate in optical fibres, and key problems associated with real …

An investigation into the use of smectitic clay soil for the containment and treatment of petrochemical waste
… is required concerning the chemical and physical behaviour of organic chemicals in the soil environment in order to implement measures that will protect groundwater but also permit reasonable usage of soil for waste containment. This study deals with the interactions of a smectitic clay …

Advanced design and experimental validation of MRI contrast agents for fluid pressure mapping using microbubbles
… used to assess the contrast agent for its physical behaviour. These techniques include rheometry, light scattering, optical and scanning electron microscopy. Six MRI experiments in total were performed: The first two experiments use standard spin echo imaging techniques to test various …

Modified Gravity with Torsion
… by high precision cosmological and astrophysical data. The work in this thesis focuses on applications of a particular modified gravity theory, the extended Weyl Gauge Theory (eWGT), that was recently developed by Prof. Lasenby and Prof. Hobson. The applications corresponds to subsets of …

The interaction of periodic surface gravity waves with slowly varying water currents
… plus a detailed discussion of the qualitative physical behaviour implied by the equations. Particular solutions are usually given only where they serve to clarify the general method or some physical feature of the analysis. The thesis proper is introduced by a derivation of wave kinematics on …

Combined NMR and simulation study of carbohydrate linkage dynamics
… however, will depend on understanding its physical behaviour, so that intelligent modifications can be made to enhance its properties. The most effective way of changing a polymer's properties is by modification at the chemical level, since ultimately it is this which determines the …

Microstructural evolution of silicate immiscible liquids in solidifying ferrobasalts
… rapidly cooled rocks. Crucially, the different physical properties of these unmixed liquids mean that they may migrate and separate within a granular medium, forming chemically distinct accumulations. I combine experiments, geochemistry, image analysis and field observations to better quantify …
