No full textGSWA Collie Uranium Grid Geodetic
No full textMaintenance and Update Frequency: notPlannedStatement: This GSWA Collie Uranium Grid Geodetic is an airborne-derived radiometric uranium grid for the South West (Cape Leeuwin - Collie), WA, 2011. The survey was acquired under the project No. 1244 for the geological survey of WA. The grid has a cell size of 0.00042 degrees (approximately 42m). A total of 101882 line-kilometres of data at a line spacing between 200m and 400, and 50m terrain clearance were acquired to produce this grid. This radiometric uranium grid shows uranium element concentration of the South West (Cape Leeuwin - Collie), WA, 2011 in units of parts per million (or ppm). Noise-adjusted singular value decomposition (NASVD) has been applied to the data. NASVD is a spectral component analysis procedure for the removal of noise from gamma-ray spectra. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). This Index is also available online at http://pid.geoscience.gov.au/dataset/79134.

Lithium transport in crown ether polymers
No full textA series of 12-, 13-, and 14-membered crown ether rings bearing polymerisable side-chains has been synthesised. The crown ethers were attached to a methacrylate or acrylate polymerisable group either via a short link (Ring-CH(_2)-O-Polymer) or via a spacer group. Both hydrocarbon and ethylene oxide spacer groups were used, giving structures of the form (Ring-CH(_2)-O-(CH(_2))(_6)-O-Polymer) and (Ring-CH(_2)-O-((CH(_2)CH(_2))(_2)O)-Polymer). The ethylene oxide chain can potentially bind to a Li(^+) dopant ion. The relative Li(+) binding affinity of 12-, 13-, and 14-membered mono- and disubstituted crown ethers has been assessed by variable temperature (^13)c and (^7)Li NMR. The crown ether bearing monomers were polymerised using standard free-radical polymerisation methods to yield amorphous materials whose glass transition temperature (T(_g)) was controlled principally by the nature of the spacer group. On doping with lithium triflate (LiCF(_3)SO(_3)), the polymers exhibit high ionic conductivity. The conductivity was primarily dependent on polymer T(_g), but was also found to be higher for 12-crown-4 based systems than for 13-crown-4 and 14-crown-4 based analogues. This behaviour was consistent with the results of the NMR studies, which showed that Li(^+) exchange occurs more readily between 12-crown-4 rings than 13- or 14-crown-4 rings. The NMR studies also showed that 12-crown-4 systems have a higher tendency to form 2:1 (ring : Li(^+)) complexes. Within a polymer matrix, the presence of 2:1 complexes allows Li(^+) migration via an association-disassociation mechanism, avoiding the high energy intermediate state of a free or weakly bound Li(^+) ion. The greater encapsulation provided by 2:1 complexation may also aid in ion pair separation
TARIFFS AND SUBSIDIES UNDER ASYMMETRIC OLIGOPOLY: AD VALOREM VERSUS SPECIFIC INSTRUMENTS
No full textThis paper analyses the welfare effects of ad valorem and specific trade policy instruments (import tariffs and production subsidies) under asymmetric Cournot oligopoly and then compares the efficiency of ad valorem with specific instruments. It is shown that these trade policy instruments have rationalization effects similar to those in Collie (European Journal of Political Economy, Vol. 9 (1993), pp. 275-280), and that an ad valorem production subsidy will have an additional negative rationalization effect. Also, it is shown that an ad valorem production subsidy yields lower welfare than a specific production subsidy due to this additional negative rationalization effect, and that combining ad valorem and specific instruments yields welfare gains.

Albany-Fraser Block (Collie, Pemberton), WA, 1980 (P456), radiometric line data, AWAGS levelled
No full textMaintenance and Update Frequency: notPlannedStatement: This Albany-Fraser Block (Collie, Pemberton), WA, 1980 (P456), radiometric line data, AWAGS levelled is an airborne-derived radiometric data for the Albany-Fraser Block (Collie, Pemberton), WA, 1980. The data was acquired under the project No. 456 for the geological survey of WA. A total of 18835 line-kilometres of data at a line spacing of 1500m were acquired during this survey. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data (Milligan et al., 2009). This survey data is essentially levelled to AWAGS. Noise-adjusted singular value decomposition (NASVD) has been applied to the data. NASVD is a spectral component analysis procedure for the removal of noise from gamma-ray spectra. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014).

DRD2 is associated with fear in some dog breeds
No full textBehavioral problems occur frequently in dogs and represent a significant threat to dog welfare. Anxiety, phobias, and fears comprise most of the canine behavioral conditions. The identification of an association between specific behavioral phenotypes and genetic variants of candidate genes would be a valuable tool in selection for dogs less susceptible to anxiety and fear, which may improve animal welfare. The DRD2 gene encodes the dopamine receptor 2. In this study, we found 8 SNPs in the DRD2 gene of the Havanese, a breed that shows large variation in a behavioral phenotype that manifests itself as a tendency to react fearfully by withdrawing in social situations. Significant associations were detected between 2 SNPs in exon 2 of the DRD2 gene and increased social fear in Havanese dogs (n = 158), as evaluated through observation by an external evaluator (respective allelic odds ratio: 4.35, 4.07) and through owner questionnaires (respective allelic odds ratio: 1.96, 2.2). Because different types of fear-related behavioral disorders commonly co-occur, the SNPs in exon 2 were also investigated for possible association to noise reactivity in 5 breeds: Havanese (n = 121), collie (n = 94), Irish soft-coated wheaten terrier (n = 44), Nova Scotia duck tolling retriever (n = 33), and standard poodle (n = 29). Significant associations were detected between SNPs in exon 2 of the DRD2 gene and noise reactivity in the Irish soft-coated wheaten terrier (respective allelic odds ratio: 2.64, 2.88) and collie (allelic odds ratio: 3.03). The same SNP alleles were associated with the beneficial phenotypes in the 3 breeds
End-to-end foodweb control of fish production on Georges Bank

The definitive version was published in ICES Journal of Marine Science: Journal du Conseil 66 (2009): 2223-2232, doi:10.1093/icesjms/fsp180.The ecosystem approach to management requires the productivity of individual fish
stocks to be considered in the context of the entire ecosystem. In this paper, we derive an
annual end-to-end budget for the Georges Bank ecosystem, based on data from the
GLOBEC program and fisheries surveys for the years 1993-2002. We use this budget as
the basis to construct scenarios that describe the consequences of various alterations in
the Georges Bank trophic web: reduced nutrient input, increased benthic production,
removal of carnivorous plankton such as jellyfish, and changes in species dominance
within fish guilds. We calculate potential yields of cod and haddock for the different
scenarios, and compare the results with historic catches and estimates of maximum
sustainable yield (MSY) from recent stock assessments. The MSYs of cod and haddock
can be met if the fish community is restructured to make them the dominant species in
their respective diet-defined guilds. A return to the balance of fish species present in the
first half of the 20th century would depend on an increase in the fraction of primary
production going to the benthos rather than to plankton. Estimates of energy flux through
the Georges Bank trophic web indicate that rebuilding the principal groundfish species to
their MSY levels requires restructuring of the fish community and repartitioning of energy
within the food web.We acknowledge NOAA-CICOR award NA17RJ1233 (J.H. Steele) and NSF
