Widening the gap – Indigenous affairs
No full textThe author points out the implications for aboriginal Australians of the decision to cut funding for Aboriginal and Torres Strait Islander Services. Curran gives individual examples to show how early intervention to give aboriginals effective access to services and avoid jail helps to close the gap between aboriginal and non-aboriginal people and saves taxpayers’ money

Excited state intramolecular proton transfer (ESIPT) efficiency enhancement in phenols due to o-alkyl groups
No full textWidely distributed in nature, phenols are a class of chemical compounds that consist of a hydroxyl group bonded directly to a carbon atom in an aromatic ring. Phenols are weak acids with pKa values around 10, but they become dramatically more acidic after they absorb light and enter their singlet excited state. The increased acidity of excited phenols can result in a reaction called Excited State Intramolecular Proton Transfer (ESIPT), in which an acidic hydrogen atom is transferred to a basic site on the same molecule. Fundamental to the function of human sunscreens, as well as the natural mechanisms used by plants and animals to protect themselves from the damaging effects of UV light, this process is biologically important.Four phenols were prepared with alkyl groups increasing in size at the ortho-position of the phenol OH via bromination, methylation, Suzuki coupling, and demethylation: 6-methyl-2-phenylphenol (22), 6-ethyl-2-phenylphenol (23), 6-isopropyl-2-phenylphenol (24), and 6-tert-butyl-2-phenylphenol (25). All four compounds were characterized using 1H nuclear magnetic resonance (NMR) spectroscopy and investigated using product studies, fluorescence spectroscopy, and mass spectrometry (MS). To determine ESIPT quantum yields, MS was used to track deuterium incorporation. The widely studied 2-phenylphenol (8) which only has a hydrogen at the 6-position was used as a reference standard.Compounds 22-25 successfully underwent ESIPT at the 2’-position followed by reverse proton transfer (RPT) to return to starting material. Quantum yields for 22-25 were 0.20, 0.24, 0.26, and 0.30, respectively, which suggested that the ESIPT reaction became increasingly efficient as the alkyl group added to the 6-position became larger. The addition of the tert-butyl group improved the ESIPT reaction efficiency the most dramatically, by nearly quadrupling the quantum yield of ESIPT compared to 8 from the literature (Φ = 0.082). Fluorescence measurements were also carried out to support the proposed mechanism. These results are consistent with the hypothesis that increasing the size of R groups added at the 6-position can increase ESIPT efficiency by forcing the molecule into a conformation that is ideal for ESIPT, where the phenol OH is pointed toward the phenyl ring.</p

Numerical prediction of vortex dynamics in inviscid sheet cavitation
No full textRecent studies have indicated that mass transfer models are able to correctly reflect the sheet cavitation dynamics of inertia driven flows, given that the mass transfer model constants governing the source term magnitude are sufficiently large (Koukouvinis and Gavaises 2015) and that enough temporal resolution is provided (Schenke and Van Terwisga 2017). The inertia driven dynamics, characterised by cavity collapse time, shedding frequencies and local pressure impact frequencies, were shown to be insensitive to variations of the mass transfer coefficients in this limit.This study focuses on an inviscid cavitating flow around a NACA0015 hydrofoil. The flow dynamics are driven by the re-entrant jet as the main mechanism of cavity shedding. A threshold of mass transfer magnitude, temporal and spanwise spatial resolution is identified, beyond which the frequency of local pressure impacts is model parameter independent. Although the excact values of peak pressure loads remain time step size, grid size and model parameter dependent, the sheet cavitation dynamics are considered as well resolved in this regime as far as shedding frequency and characteristic cavity collapse time are concerned. The results are compared to experimental results by Van Rijsbergen et al. (2012).Based on this, the study further focuses on the mechanism of vorticity generation and vorticity break-up, causing potentially erosive cavitating structures such as horseshoe cavities (Dular and Petkovˇsek 2015).Accepted Author ManuscriptShip Hydromechanics and Structure
“I will Tell my Story, and my Reader shall Judge for Me”: Mary Shelley’s Stories for The Keepsake
No full textBetween 1823 and 1839 Mary Shelley was a prolific writer and a steady contributor
to the annuals. After she moved back from Italy to London, she published
four novels and twenty-one stories as well as some poetical pieces. Her
literary contributions for the annuals were accompanied by illustrations of the
sort that characterized the periodical market of annuals and gift books of the
time. In many of these stories Mary Shelley employs gothic elements such
as the supernatural, the dangerous, and the mysterious, linking her later production
with her successful publication, Frankenstein. Thus, Shelley’s stories
written for the annuals can be read as an extension and development of the
gothic elements employed by the author in her first novel. Specifically, the
author is building on both the enduring public taste for those gothic elements
employed by Ann Radcliffe as well as experimenting with the new genre of the
short story. Mary Shelley’s editorial relationship with The Keepsake—a very
successful periodical for women that represented the refinements and elegance
pervading the English consumerist society of the 1830s—became a fruitful
endeavor not only for financial income, but also as a site of literary experimentation
in terms of genre and content
Addiction recovery stories: Neil Curran in conversation with Lisa Ogilvie
No full textPurpose This paper aims to explore the transition from addiction to recovery. It is the second in a series of recovery stories that examine candid accounts of addiction and recovery. Shared components of recovery are considered, along with the change and growth needed to support the transition. Design/methodology/approach The CHIME framework comprises five elements important to recovery (Connectedness, Hope, Identity, Meaning and Empowerment). It provides a standard to qualitatively study mental health recovery, having also been applied to addiction recovery. In this paper, an element for Growth is included in the model (G-CHIME), to consider both recovery, and sustained recovery. A first-hand account of addiction recovery is presented, followed by a semi-structured e-interview with the author of the account. This is structured on the G-CHIME model. Findings This paper shows that addiction recovery is a remarkable process that can be effectually explained using the G-CHIME model. The significance of each element in the model is apparent from the biography and e-interview presented. Originality/value Each account of recovery in this series is unique, and as yet, untold
Finite mass transfer effects in cavitation modelling
No full textOne of the key aspects classifying the various approaches in numerical simulation of cavitating flows is the equilibrium flow assumption. It states that internal processes in the flow always occur instantaneously compared to the time scale of the flow (s. Sezal (2009)). As a consequence, the density-pressure trajectory in a barotropic flow may follow a unique curve. Contrary to the equilibrium flow assumption, one may assume that the time to achieve a new state is governed by the magnitude of a finite mass transfer source term in a volume fraction transport equation (s. Asnaghi et al. (2015)). In this case, the set of possible density-pressure states is not predefined, but strongly depends on the rate at which pressure changes. Although it has been pointed out by Koukouvinis and Gavaises (2015) that the equilibrium assumption for a barotropic flow would theoretically be mimicked by the mass transfer model if the finite transfer rate tended to infinity, the model parameters triggering the finite transfer rate are generally considered as empirical (s. Frikha et al. (2008)).In this paper, effects of the finite mass transfer rate with special focus on condensation will be studied in detail. First, a cavity collapse will be considered to demonstrate how the finite transfer source term must be modified to satisfy the equilibrium flow assumption. Second, a single bubble collapse is studiednumerically and effects of the finite mass transfer rate will be discussed.Accepted Author ManuscriptShip Hydromechanics and Structure
