Master's thesis of Applied Science

This research focuses on two key research questions: how to measure spatial accessibility to green space in urban areas at fine resolution; and what is the status of spatial inequity in accessibility to green space in the MMA. Guided by the two research questions and based on a systematic review of literature on accessibility in general accessibility to green space in particular, a methodology has been developed for producing results needed to answer the research questions.

Brachytherapy is a form of radiotherapy in which radioactive sources are placed at short distances from, or even inside the target volume. The use of high dose rate brachytherapy is a widely accepted and clinically proven treatment for some stages of prostate cancer. The aim of this project was to investigate potential improvements on two of the most important aspects of high dose rate (HDR) and pulsed dose rate (PDR) prostate brachytherapy - prostate definition and treatment delivery verification.

This research investigates other built-in sensors and develops methods for improving the accuracy of indoor positioning. Combination with the wireless network, it can be a viable alternative solution for the indoor positioning purposes of the smartphone users. The main advantage of this solution is that it can be deployed with a minimal cost, as no specialized hardware is necessary for setting up the system.

To achieve the aim, the first objective is preliminary experiments on preparation of polypropylene blends with silicone elastomer masterbatch and characterize by analysis of mass composition, mechanical properties, and dynamic mechanical properties to investigate any improvement of properties. The silicone elastomer masterbatch will then be substituted with propylene-maleic anhydride graft copolymer waxes or other compatibilizers.

This purpose of this work was to investigate the patient radiation doses and image quality of a Philips/Agfa computed radiographic (CR) system and a Philips indirect-capture digital radiographic (DR) system in a paediatric setting. A CDRAD digital radiographic contrast-detail phantom was used to assess radiographic image quality. Perspex slabs of three different thicknesses (6, 11 and 16 cm) were used to simulate paediatric patients of three arbitrary ages.

This research has raised the question of whether the vibration transmission at a wall junction depends on how the wall is excited (by either a sound wave or a mechanical shaker). The aim of this research is to investigate this question and hence contribute to the revision of the series of standards. Villot and Guigou-Carter (2000) have considered this problem but their equations (10) and (13) appear to be in error. This research will endeavour to derive the correct equations and r epeat Villot and Guigou Carter’s calculations.

The primary objective of the research is to develop a balanced scorecard framework for construction contractors and measu re performance of contractors using that framework. The results of the questionnaire survey carried out and follow-up interviews conducted among 34 senior managers in Melbourne revealed that the above performance measurement framework is appropriate to use in a contracting organisation. The respondents perceive that the process management perspective measurement is more desirable than others.

This history of antimicrobials is marked with impressive discoveries, the majority of which have their origin in natural products. However in this work, the antimicrobial activity of β- nitrostyrenes and related compounds of synthetic origin is reviewed and investigated with a particular focus on the influence of fluorine functionality. Various fluorinated β-methyl-β-nitrostyrene compounds were prepared, their minimum inhibition concentration in cultures of Gram positive, Gram negative and a fungus and their lipophilicity was determined.

The aim of this thesis is to ensure that accurate calibration factors are provided to radiotherapy clinics when moving to the new linac-based primary standard calibrations. Specifically, this thesis quantifies the error introduced when using a calibration factor from the ARPANSA Elekta linac on a Varian high energy platform beam at 6 MV.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The alumina refining industry is one of a number of global industries that produce process waters containing mercury. The research program detailed in this dissertation focuses on processes for removing mercury from Bayer digestion condensate streams. Bayer refinery digestion condensate is chemically unique because it exhibits high pH and is chemically reducing, thermodynamically favouring the presence of elemental mercury.

This study investigated trace essential metals (Cu, Zn and Cr) and non-essential metals (Pb, Cd and Hg) in water, sediment and tissues of water spinach, snake head fish and swamp eel from the Saigon River. Sampling was conducted from January to December 2004 at three sites. Three water and sediment samples, edible parts of twenty water spinach (Ipomea aquatica) samples (leaves and stems), twenty snake head fish (Channa striata) and twenty swamp eels (Monopterus albus) were collected at each site.

This thesis documents a research program in which Australian grown Danshen extracts and related bioactive compounds have been demonstrated to be effective in scavenging free radicals, namely ROS generation, in a cell free system and NADPH oxidase derived superoxide (O2-) generation in vascular tissue (rat aorta). Danshen extracts, both aqueous and ethanol, and their active compounds (Tanshinone IIA, Salvianolic Acid B and Danshensu) demonstrated anti-oxidant activity however findings exhibited stronger activity in a cell free system than in the aortic vascular tissue.

This study investigated the sublethal effects of salinity on four macroinvertebrate species commonly occurring in Australian freshwater ecosystems. These were; the introduced worm Lumbriculus variegatus Müller (Annelida: Oligochaeta), the introduced snail Physa acuta Draparnaud (Gastropoda: Physidae), the shrimp Paratya australiensis Kemp (Decapoda: Atyidae) and the midge Chironomus tepperi Skuse (Diptera: Chironomidae). The effects of salinity on growth, development and reproduction of these species were investigated through a series of laboratory tests.

This research thesis will explore, from the results of the life experiences of families and couples who lived through the Wangary fire (South Australia, January 2005), the complexities of work, parenting, relationships, changing responsibilities and roles and sense of place. All of these factors have relevance to the review and development of bushfire management policy and related community awareness and preparedness programs.
