Respirable Crystalline Silica Exposures among Stoneworkers involved in Stone Restoration Work
(2014-05-02)
Exposure to respirable crystalline silica (RCS) can result in the development of a range of adverse health effects including silicosis and lung cancer. Although exposure to RCS has been characterised in many occupational ...
A morpho-kinematic and spectroscopic study of bipolar planetary nebulae
(2015-09-28)
In this thesis, studies of the kinematic properties for a sample of Galactic bipolar planetary nebulae, based on optical and infrared observations, were performed us- ing a morpho–kinematic code, optical and NIR diagnostic ...
Semi-automated segmentation of pleural effusions in 3D thoracic X-ray computed tomography
(2014-09-27)
A pleural effusion is excess fluid that collects in the pleural cavity, the fluid-filled space that surrounds the lungs. Surplus amounts of such fluid can impair breathing by limiting the expansion of the lungs during ...
Structure and evolution of classical Nova Shells
(2017-09-22)
This thesis focuses on shells ejected during classical nova events. Novae are due to thermonuclear runaway on the surface of a white dwarf in a binary system. The work herein concentrates on nova shells individually to ...
Quantum dots in bio-imaging and drug delivery
(2015-11-23)
This work explores a range of bionanomaterials, with particular attention to their influence on cell growth, function and fate. Also the issue of intracellular nanoparticles quantification has been addressed in experimental ...
A study on human error, safety culture and risk in radiation oncology
(2017-05-12)
In 2010 the New York Times wrote a series of articles on different radiation procedures including radiotherapy treatments. These articles highlighted a number of incidents that have occurred in the course of radiotherapy ...
Ultrasound imaging in radiotherapy and dosimetric quantification with Monte Carlo techniques
(2017-12-21)
This thesis considered the use of ultrasound-based image guidance systems, employed to account for internal motion of the prostate gland during radiotherapy. A clinical evaluation of the Clarity soft tissue visualisation ...
IMPAIR: Massively parallel regularised Richardson-Lucy deconvolution on heterogeneous hardware
(2017-10-27)
This thesis investigates the comparative performance of multicore CPU and general purpose GPU on a commodity desktop computer. To investigate this, an image deconvolution software package (IMPAIR) was updated from its ...
Air to sea gas exchange of CO2 in the north-east Atlantic Ocean
(2011-12-08)
Atmospheric carbon dioxide concentrations have been rising for the past 200 years, and started increasing at a faster rate during the last 60 years. The world's oceans act as a reservoir for large amounts of CO_2. How they ...
Measuring Aerosol Particle Behaviour due to Human Activity Indoors for Re-Exposure Evaluation
(2013-10-31)
The transport and fate of hazardous aerosols, including those of a radiological and biological nature, have been extensively studied both experimentally and theoretically. However, less attention has been given to the ...
