Transition-metal complexes of the types [Re(CO)3Cl(NN)], [Re(CO)3py(NN)]+, and [Cu(PPh3)2(NN)]+, where NN = 4,4′-bis(5-phenyl-1,3,4-oxadiazol-2-yl)-2,2′-bipyridine (OX) and 4,4′-bis(N,N-diphenyl-4-[ethen-1-yl]-aniline)-2,2′-bipyridine (DPA), have been synthesized and characterized. Crystal structures for [Re(CO)3Cl(DPA)] and [Cu(PPh3)2(OX)]BF4 are presented. The crystal structure of the rhenium complex shows a trans arrangement of the ethylene groups, in agreement with density functional theory calculations. The structure of the copper complex displays the planar aromatic nature of the bpy–oxadiazole ligand. Density functional theory modeling of the complexes was supported by comparison of calculated and experimental normalized Raman spectra; the mean absolute deviations of the complexes were <10 cm–1. The Franck–Condon state was investigated using UV–vis and resonance Raman spectroscopic as well as density functional theory computational techniques. It was shown that the lowest energy absorption peaks are metal to ligand charge transfer and ligand-centered charge transfer for the oxadiazole- and diphenylaniline-substituted bipyridine ligands, respectively. The lowest energy excited states were characterized using transient emission and absorption spectroscopic techniques in conjunction with density functional theory calculations. These showed that the DPA complexes had ligand-centered nonemissive “dark” states with lifetimes ranging from 300 to 2000 ns.
'Redneck, Barbaric, Cashed Up Bogan? I Don't Think So': Hunting And Nature In Australia, Michael Adams
'Redneck, Barbaric, Cashed Up Bogan? I Don't Think So': Hunting And Nature In Australia, Michael Adams

Hunting is a controversial activity in Australia, and much debated in international research. Positions range from 'the first hunters were the first humans' to the 'meat is murder' argument. There is, however, very little research on non-Indigenous hunting in Australia, particularly on the social aspects, but also on biological and ecological issues. In contrast to a general lack of research on non-Indigenous hunting, there is extensive literature on Indigenous hunting. This paper reviews initial research exploring hunting participation and motivation in Australia, as a window into further understanding connections between humans, non-humans and place. My focus is on an analysis …
Secure Id-Based Linkable And Revocable-Iff-Linked Ring Signature With Constant-Size Construction, Man Ho Au, Joseph K. Liu, Willy Susilo, Tsz Hon Yuen
Secure Id-Based Linkable And Revocable-Iff-Linked Ring Signature With Constant-Size Construction, Man Ho Au, Joseph K. Liu, Willy Susilo, Tsz Hon Yuen

In this paper, we propose a new ID-based event-oriented linkable ring signature scheme, with an option as revocable-iff-linked. With this option, if a user generates two linkable ring signatures in the same event, everyone can compute his identity from these two signatures. We are the first in the literature to propose such a secure construction in an ID-based setting. Even compared with other existing non ID-based schemes, we enjoy significant efficiency improvement, including constant signature size and linking complexity. Our scheme can be also regarded as a normal ID-based ring signature. We are also the first to propose such a …

Quartz and carbonaceous materials, which are used in the production of silicon as well as electrodes and refractories in the silicon furnace, contain trace elements mostly in the form of oxides. These oxides can be reduced to gaseous compounds and leave the furnace or stay in the reaction products—metal and slag. This article examines the behavior of trace elements in hydrothermal quartz and quartzite in the reaction of SiO2 with Si or SiC. Mixtures of SiO2 (quartz or quartzite), SiC, and Si in forms of lumps or pellets were heated to 1923 K and 2123 K (1650°C and 1850°C) in …

Ice core data are combined with RACMO2 regional climate model (RCM) output (1958-2010) to develop a reconstruction of the Greenland ice sheet net snow accumulation rate (Ât(G)) spanning years 1600-2009. Regression parameters from RCM output regressed on 86 ice cores are used with available cores in a given year resulting in the reconstructed values. Each core site’s residual variance is used to inversely weight the cores’ respective contributions. The interannual amplitude of the reconstructed accumulation rate is damped by the regressions and is thus calibrated to match that of the RCM data. Uncertainty and significance of changes is measured using …

Purpose: The purpose of this study was to measure the dose distributions for different Radiation Oncology Physics and Engineering Services, Australia (ROPES) type eye plaques loaded with I-125 (model 6711) seeds using GafChromic R EBT3 films, in order to verify the dose distributions in the Plaque SimulatorTM (PS) ophthalmic 3D treatment planning system. The brachytherapy module of RADCALC R was used to independently check the dose distributions calculated by PS. Correction factors were derived from the measured data to be used in PS to account for the effect of the stainless steel ROPES plaque backing on the 3D dose distribution. …

Drive-in steel storage racks represent a popular alternative to the more common selective racks when available space is restricted or when storing the same good. In drive-in racks, the forklift truck drives into the rack and stores the pallets on beam rails on the "first-in last-out" principle. Recent experimental studies have shown that by acting as horizontal ties between uprights, pallets significantly influence the structural behaviour of the rack. However, due to the uncertainty in the degree of friction between the rail beams and the pallets, current industry design practice does not consider this effect. This paper quantifies the influence …
