The race that stops the nation also holds many weird and wonderful stories
No full textIt's that first Tuesday in November again, which means that famous Australian horse race - you know the one - will be run this afternoon. It has produced many wonderful stories in its long history and today, author Wayne Peake writes about some of the lesser known (and rather quirky) Cup tales

Peake Creek Seismic, Gravity (P197046), gravity point data
No full textMaintenance and Update Frequency: notPlannedStatement: This Peake Creek Seismic, Gravity (P197046), gravity point data contains ground gravity point data for the Peake Creek Seismic, Gravity (P197046) survey acquired for Pexa Oil NL. This dataset contains a total of 378 point data values. The data is located in SA and were acquired in 1970. The point located data were collected in grid layout at an average station spacing of 533 metres.
Terrain corrections were calculated using the INTREPID Geophysics software package. The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose.
All data are provided in EPSG:4283 coordinates, Australian Height Datum (AHD) and gravity datum of AAGD07. The units are degrees, meters, and micrometres per second squared, respectively.

Intrepid Geophysics, http://www.intrepid-geophysics.com.Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.<br/> This Peake Creek Seismic, Gravity (P197046) contains a total of 378 point data values acquired at a spacing of 533 metres.

Establishing an interconnected mineralisation history of the Mount Isa Province and the Peake and Denison Domain, northeastern Gawler Craton
No full textThis item is only available electronically. Whole thesis (as available).The Mesoproterozoic period saw extensive IOCG mineralisation of the Mount Isa Province at c. 1550-1490 Ma. Tectonic reconstructions of Paleoproterozoic and early Mesoproterozoic Australia situate the Peake and Denison Domain of the northeastern Gawler Craton at the boundary of the NAC and SAC during this time. Recent geochronology of zircon and titanite suggests an interconnected hydrothermal history between the Peake and Denison Domain and Mount Isa Province during the early Mesoproterozoic. This project presents new U-Pb LA-ICP-MS geochronology of zircon and titanite, and multi-method (U-Pb, Lu-Hf) LA-ICP-MS geochronology of apatite from IOCG-style mineralised core of the Peake and Denison Domain. Zircon analysis interprets a c.1775 Ma upper intercept age for the metasedimentary protolith. Titanite analysis constrains the timing of mineralisation to 1500 Ma. Apatite U-Pb analysis presents mineralisation ages of c.1490-1470 Ma, while Lu-Hf analysis constrains the timing of mineralisation to c.1530-1490 Ma. These results suggests that the c.1550-1490 Ma mineralising systems of the Mount Isa Province also governed the Peake and Denison Domain and subsequent northeastern Gawler Craton, separate from the c.1600-1570 Ma mineralising system of the central Gawler Craton. These interpretations align with the Mesoproterozoic amalgamation of the NAC and SAC. Establishing an interconnected mineralisation history of the Peake and Denison Domain and Mount Isa Province implies that the northeastern portion of the Gawler Craton is likely prospective for Isan-style mineralisation, thereby creating incentive for future mineral exploration.Thesis (B.Sc.(Hons)) -- University of Adelaide, School of Physical Sciences, YEA
Fine structure of the peaks of the correlation function in acoustic black holes: A complete analytical model
No full textThe detailed structure of the peaks appearing in the density-density correlation function for an acoustic black hole formed by a Bose-Einstein condensate is analytically discussed for a particular, but physically meaningful, sound velocity profile that allows the field modes to be exactly computed

The acoustics of curved and lined cylindrical ducts with mean flow
No full textThis thesis considers linear perturbations to the steady flow of a compressible inviscid perfect gas along a cylindrical or annular duct. Particular consideration is given to the model of the duct boundary, and to the effect of curvature of the duct centreline. For a duct with a straight centreline and a locally-reacting boundary, the acoustic duct modes can be segregated into ordinary duct modes and surface modes. Previously-known asymptotics for the surface modes are generalized, and the generalization is shown to provide a distinctly better approximation in aeroacoustically relevant situations. The stability of the surface modes is considered, and previous stability analyses are shown to be incorrect, as their boundary model is illposed. By considering a metal thin-shell boundary, this illposedness is explained, and stability analysed using the Briggs–Bers criterion. The stability of a cylindrical thin shell containing compressible fluid is shown to differ significantly from the stability for an incompressible fluid, even for parameters for which the fluid would otherwise be expected to behave incompressibly. The scattering of sound by a sudden hard-wall to thin-shell boundary change is considered, using the Wiener–Hopf technique. The causal acoustic field is derived analytically, without the need to apply a Kutta-like condition or to include an instability wave, as had previously been necessary. Attention is then turned to a cylindrical duct with a curved centreline and either hard or locally-reacting walls. The centreline curvature (which is not assumed small) and wall radii vary slowly along the duct, enabling an asymptotic multiple scales analysis. The duct modes are found numerically at each axial location, and interesting characteristics are explained using ray theory. This analysis is applied to a hard-walled RAE 2129 duct, and frequency-domain solutions are convolved to give a time-domain example of a pulse propagating along this duct. Finally, some numerical work on the nonlinear propagation of a large-amplitude pulse along a curved duct is presented. This is aimed at modelling a surge event in an aeroengine with a convoluted intake
Gary D. Peake Excavating v. Town Bd. of Hancock, 93 F. 3d 68 - Court of Appeals, 2nd Circuit 1996
No full textPlaintiffs-appellants Gary D. Peake Excavating, Inc. and Gary D. Peake (together, the Plaintiffs ) appeal from a judgment entered in the United States District Court for the Northern District of New York (McAvoy, Ch. J.) granting in part their motion for summary judgment and granting in part the motion for summary judgment of defendant-appellee Town Board of the Town of Hancock. The district court determined that Section 5 of Local Law No. 1 of the Town of Hancock ( Law No. 1 or the ordinance ) violated the Commerce Clause of the United States Constitution by discriminating against out-of-state waste. The district court severed Section 5 from Law No. 1 and determined that the remainder of the ordinance did not violate the Commerce Clause. On appeal, the Plaintiffs contend that severance of Section 5 of Law No. 1 was inappropriate, and that Law No. 1, following the severance of Section 5, violates the Commerce Clause. For the following reasons, we affirm the judgment of the district court
