Natural products

Since the early days, natural products have played a significant role in drug discovery and development. However, the extraction process of these compounds often includes many complex steps, consumes a lot of energy and a large volume of solvents, which can have a significant impact on the environment as well as human health. Therefore, it is necessary to find better ways to improve the yield of extraction, while minimizing risks that may affect the environment and humans.

Atrophic scars are the result of natural healing leading to the formation of replacement fibrous tissue. The atrophic scar is a common undesirable complication of acne, chickenpox, herpes, trauma, etc. Although the disease does not cause dangerous complications, due to the location of the lesions on the face, it causes great aesthetic and psychological obstacles, and the patient is less confident in communication, profoundly affecting the patient's quality of life and labor productivity.

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.

3D animation software is extensively used to create graphics for special effects sequences in live-action films, in animated feature film production and for the generation of computer games and virtual reality content. It is a commonly held view within the computer graphics community that 3D animation software is ―just another tool‖ for self-expression. This research questions that view by examining the inherent nature of the tool itself. In doing so, some of the philosophical assumptions embedded in the design of the new digital tool are revealed.

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.

This research explores whether Environmental Management Accounting can be applied to assist an Australian cogeneration company in improving both its financial performance as well as its environmental performance. Cogeneration or 'combined heat and power', in this particular case, involves the simultaneous production of heat and electricity using a single fuel, that is, natural gas. The heat generated is then used to produce steam to meet the customers' requirements as well as boost the production of electricity.
