Philip Kindred Dick (December 16, 1928 – March 2, 1982) was an American science fiction novelist, short story writer, and essayist. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in mysticism and theology. He often drew upon his own life experiences and addressed the nature of drug use, paranoia and schizophrenia, and mystical experiences in novels such as A Scanner Darkly and VALIS.

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 main aims of physical geodesy are to study the shape of the Earth, its gravity field and the geoid which is an equipotential surface closest to the mean sea level. Precise geoid determination has been an important research topic in geodesy and geophysics in the past two decades. Scientists and government agencies all around the world have made great efforts on the development of highaccuracy geoid models.

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 examines how parametric loudspeakers may be considered unique acousmatic musical instruments; how the parametric acoustic array (PAA) can potentially make new forms of music and listening experiences; and how PAA-design problems can be overcome. Interdisciplinary in nature, the study uses grounded theory and experimental music practice within a design research methodology. Theory emerges from data, in concert with analysis and framing that draws on areas such as electroacoustic music, spatial composition, acoustics, PAA science/theory, modulation theory, and medium theory.
