Summary The report provides a sound understanding of an ericoid endophyte associated with members of the Epacridaceae (Western Australian native heaths) in both soil and axenic culture, and describes for…
Summary A portable thoron-in-breath unit has been designed, constructed and then used to measure the quantity of thoron exhaled in the breath of employees in the mineral sands industry who…
Summary Mobile Metal Ion (MMI) responses were demonstrated on soil samples from sponsors’ sites, and showed subtle anomalies in active depositional environments where conventional geochemical methods had failed. The MMI…
Summary A novel application of recently discovered aromatic biomarkers has been used to characterise crude oils and their source rocks in a manner that enables genetic relationships to be recognised.…
Summary The development of a concept for a device to prevent a conveyance from free-falling down a shaft after a hoisting system failure is presented, and a survey of drum…
Summary New technologies to image coal seams using seismic methods in areas previously thought unsuitable for this method were established. Field studies were carried out in the Bowen, Sydney and…
Summary This report focussed on specific needs of highly salt tolerant plants to revegetate gold mining operations. It specifically addresses five aspects of highly salt tolerant individuals within species known…
Summary Two methods of wavefield transformation were developed to pre-condition pre-stack data to attenuate long period water bottom multiples. The first method is the radial trace transform which resamples data…
Summary This report sets out methods developed to: Increase accuracy of identification of species of Phytophthora; Increase sensitivity of detecting species of Phytophthora in samples retrieved from exploration tenements; Determine…
Summary The aim of the research was to define the extent of existing subsidence features and to assess common investigation techniques used for defining the controls on the formation of…
