Item Metadata only Vegetation of North-eastern South Australia(Nature Conservation Society of S.A., 1981) Lewis, M.Item Metadata only Women in environmental sciences: an investigation of increased female participation in environmental education and careers(Department of Employment, Education & Training, 1989) Lewis, M.; Schaffer, K.This study investigates student' motivation to pursue careers and courses in environmental sciences with particular reference to the differential experiences of males and females involved in non-traditional training and career areas for females. Although males and females were found to have much in common some important differences emerged in relation to perception of skills and abilities, experience of sexual bias, relationships with educators and the importance of certain role models. These results may have implications for further research, training and education programmes, teach staff/student relationships and the role of on-the-job supervisors.Item Metadata only Current research in active control of noise(Auburn University, 1994) Hansen, C.Item Metadata only Species composition related to spectral classification in an Australian spinifex hummock grassland(Taylor and Francis, 1994) Lewis, M.This paper demonstrates a methodology for relating objective vegetation classifications to spectral classifications in order to map variation in species composition within natural vegetation. Landsat MSS data was used to map spinifex-dominated vegetation units for an island conservation reserve and oil production field on the north-western shelf of Western Australia. A significant relationship was established between an agglomerative hierarchical classification of ground samples, characterized by percentage cover of plant species and physical cover components, and a similar classification of spectral means for sample pixels. Assignment of spectral means to mapping classes was guided by both ground and spectral sample clustering. The strong relationship between the spectral classification and vegetation groups meant that cover classes mapped on the basis of spectral properties could be characterized by quantitative ground data meaningful to vegetation ecology. The resultant groups were differentiated largely on the basis of percentage cover of the three major spinifex species and the proportion of plant litter and exposed soil and surface rock. The study confirms the utility of ground cover as a quantitative variable for developing relationships with spectral classifications, and demonstrates a methodology which may have a wider application for mapping natural vegetation communities.Item Metadata only Complexation of fluorinated amino acid derivatives by b- and g-cyclodextrin in aqueous solution.

A 19F nuclear magnetic resonance study(Royal Society of Chemistry, 1995) Brown, S.; Easton, C.; Lincoln, S.Item Metadata only The quasi-stationary behavior of quasi-birth-and-death processes(Institute of Mathematical Statistics, 1995) Bean, N.; Bright, L.; Latouche, G.; Pearce, C.; Pollett, P.; Taylor, P.For evanescent Markov processes with a single transient communicating class, it is often of interest to examine the limiting probabilities that the process resides in the various transient states, conditional on absorption not having taken place. Such distributions are known as quasi-stationary (or limiting-conditional) distributions. In this paper we consider the determination of the quasi-stationary distribution of a general level-independent quasi-birth-and-death process (QBD). This distribution is shown to have a form analogous to the matrix-geometric form possessed by the stationary distribution of a positive recurrent QBD. We provide an algorithm for the explicit computation of the quasi-stationary distribution.Item Metadata only Reduction of radiated sound by use of actively controlled perforated panels(Elsevier, 1995) Burgemeister, K.; Hansen, C.Item Metadata only Stable coexistence of grandiderite and kornerupine during medium pressure granulite facies metamorphism(Mineralogical Society, 1995) Carson, C.; Hand, M.; Dirks, P.AbstractPetrological and mineral chemical data are presented for two new occurrences of co-existing borosilicate minerals in the Larsemann Hills, East Antarctica. The assemblages contain kornerupine and the rare borosilicate, grandidierite (Mg,Fe)A13BSiO9. Two distinct associations occur: (1) At McCarthy Point, 1–10 mm thick tourmaline-kornerupine-grandidierite layers are hosted within quartzofeldspathic gneiss; and (2) Seal Cove, where coexisting kornerupine and grandidierite occur within coarse-grained, metamorphic segregations with Mg-rich cores of cordierite-garnet-spinel-biotite-ilmenite and variably developed plagioclase halos. The segregations are hosted within biotite-bearing, plagio-feldspathic gneiss. Textural relationships from these localities indicate the stability of co-existing kornerupine and grandidierite.The grandidierite- and kornerupine-bearing segregations from Seal Cove largely postdate structures developed during a crustal thickening event (D2) which was coeval with peak metamorphism. At McCarthy Point, grandidierite, kornerupine and late-tourmaline growth predates, or is synchronous, with F3 fold structures developed during a extensive granulite grade, normal shearing event (D3) which occurred prior to, and synchronous with, near-isothermal decompression. Average pressure calculations on assemblages that coexist with the borosilicates at Seal Cove, indicate the prevailing conditions were 5.2–5.5 kbar at ∼ 750°C for formation of the grandidierite-kornerupine assemblage.Item Metadata only Fuzzy motion estimation(Centre of Intelligent Information Processing Systems, 1995) Kouzani, Abbas Z.; Bouzerdoum, A.; Liebelt, Michael J.Item Metadata only The effect of crossflow on Gortler vortices(1995) Otto, Stephen Robert; Denier, James PatrickItem Metadata only Dynamic effective bandwidths using network observation and the bootstrap(Telecommunication Society of Australia, 1995) Bean, N.Item Metadata only Asymptotic analysis of single resource loss systems in heavy traffic, with applications to integrated networks(Applied Probability Trust, 1995) Bean, N.; Gibbens, R.; Zachary, S.In this paper we consider the analysis of call blocking at a single resource with differing capacity requirements as well as differing arrival rates and holding times. We include in our analysis trunk reservation parameters which provide an important mechanism for tuning the relative call blockings to desired levels. We base our work on an asymptotic regime where the resource is in heavy traffic. We further derive, from our asymptotic analysis, methods for the analysis of finite systems. Empirical results suggest that these methods perform well for a wide class of examples.Item Metadata only Control of flexural vibration in a stiffened plate using piezoceramic actuators and an angle stiffener(Elsevier, 1995) Young, A.; Hansen, C.Item Metadata only Amino substituents as probes of reactions of phenyl acetates with cyclodextrins(CSIRO, 1995) Easton, C.; Kassara, S.; Lincoln, S.; May, B.Item Metadata only Sandy Inland Mouse-Pseudomys hermannsbergensis(Reed Books, 1995) Breed, W.Item Metadata only Project Database and List of Publications relating to Dryland Salinity in South Australia 1991-1994.(South Australian Dryland Salinity Committee, 1995) Fitzpatrick, R.A Technical Strategy to address dryland salinity in South Australia was released in 1990 following the formation of the State Dryland Salinity Committee in 1989. This second report complements the first by being a database of the projects that have been in progress during the years 1991-1994 and the list of publications arising from those projects. Each of the representatives on the South Australian Dryland Salinity Committee was asked to provide information on projects conducted by their institution according to a proforma. The projects and publications were logically grouped under the following nine headings: 1 state (ie State-wide), 2 South-East, 3 Riverland/Mallee, 4 Mt. Lofty, 5 Kangaroo Island, 6 Mid-North, 7 Yorke Peninsula, 8 Eyre Peninsula and 9 Other Relevant Projects. -from EditorsItem Metadata only Fergusobia/Fergusonina galls on Eucalyptus(Australasian Association of Nematologists, 1995) Davies, K.; Lloyd, J.; Taylor, G.Item Metadata only Seasonal changes of iron and dissolved organic carbon concentrations in streams in the Warren Catchment, South Australia(CSIRO Publications, 1995) Naidu, R.; De Lacy, N.; Hollingsworth, I.; Fitzpatrick, R.
