Hydroxyl Radical Formation In The Gas Phase Oxidation Of Distonic 2-Methylphenyl Radical Cations, Matthew Prendergast, Phillip A. Cooper, Benjamin B. Kirk, Gabriel Da Silva, Stephen J. Blanksby, Adam J. Trevitt

Adam Trevitt

The reactions of distonic 4-(N,N,N-trimethylammonium)-2-methylphenyl and 5-(N,N,N-trimethylammonium)-2-methylphenyl radical cations (m/z 149) with O 2 are studied in the gas phase using ion-trap mass spectrometry. Photodissociation (PD) of halogenated precursors gives rise to the target distonic charge-tagged methylphenyl radical whereas collision-induced dissociation (CID) is found to produce unreactive radical ions. The PD generated distonic radicals, however, react rapidly with O2 to form [M + O2]•+ and [M + O2 - OH]•+ ions, detected at m/z 181 and m/z 164, respectively. Quantum chemical calculations using G3SX(MP3) and M06-2X theories are deployed to examine key decomposition pathways of the 5-(N,N,N-trimethylammonium)-2-methylphenylperoxyl radical and rationalise …

A Quantitative Research On Self-Management Of Type 2 Diabetes, Rashid M. Ansari, Mark Fort Harris, Nicholas Arnold Zwar, Hassan Hosseinzadeh

Faculty of Social Sciences - Papers (Archive)

The self-management of type diabetes is an essential part of life for the patients with diabetes to have a better and a healthy lifestyle. In addition, diabetes self-management is related to enhanced knowledge of diabetes, improved overall behaviour and discipline to adhere to diet and physical activity recommendations resulting in a better outcome. Therefore, there is a need for all the required resources to be integrated in order to achieve the benefits associated with selfmanagement. Wagner et al. provided a framework for integrating the resources and supports for self-management with key components of clinical care in a chronic care model. …

Impact Of A Type 2 Diabetes Diagnosis On Mental Health, Quality Of Life, And Social Contacts: A Longitudinal Study, Xiaoqi Feng, Thomas E. Astell-Burt

Faculty of Social Sciences - Papers (Archive)

Aims The aim was to examine whether a type 2 diabetes mellitus (T2DM) diagnosis increases the odds of psychological distress, a worsening in overall quality of life, and a potential reduction in social contacts.

Method Longitudinal data were obtained from the 45 and Up Study (baseline 2006–2008; 3.4±0.95 years follow-up time). Fixed effects logistic and negative binomial regression models were fitted on a complete case on outcome sample that did not report T2DM at baseline (N=26 344), adjusted for time-varying confounders. The key exposure was doctor-diagnosed T2DM at follow-up. Outcome variables examined included the Kessler Psychological Distress Scale, self-rated quality …

An Analysis Of Metabotropic Glutamate Receptors 2/3 And 5 In Schizophrenia, Major Depression And Bipolar Disorder From The Stanley Neuropathology Consortium, N Matosin, E Frank, F Fernandez, C Deng, J Wong, Xu-Feng Huang, K A. Newell

Xu-Feng Huang

Purpose: Metabotropic glutamate receptors (mGluRs) are proposed novel therapeutic targets for a variety of brain disorders such as schizophrenia (SZ), bipolar disorder (BP) and major depression (MD). Despite their potential, the involvement of these receptors in these pathological processes is uncertain. This information is crucial to understand the efficiency of drugs that target these receptors. Methods: Using post-mortem human brains, mGluR2/3 and mGluR5 binding densities were measured in the anterior cingulate cortex of SZ, BP, MD and matched controls (CT) (n=15/group) by receptor autoradiography. Results: Whilst preliminary analyses indicated no diagnostic effect in mGluR2/3 or mGluR5 binding densities, mGluR2/3 binding …

Faculty of Social Sciences - Papers (Archive)

Introduction Physical inactivity has been described as a global pandemic. Interventions aimed at developing skills in lifelong physical activities may provide the foundation for an active lifestyle into adulthood. In general, school-based physical activity interventions targeting adolescents have produced modest results and few have been designed to be 'scaled-up' and disseminated. This study aims to: (1) assess the effectiveness of two physical activity promotion programmes (ie, NEAT and ATLAS) that have been modified for scalability; and (2) evaluate the dissemination of these programmes throughout government funded secondary schools. Methods and analysis The study will be conducted in two phases. In …

Af-Embeddability Of 2-Graph Algebras And Quasidiagonality Of K-Graph Algebras, Lisa Orloff Clark, Astrid An Huef, Aidan Sims

Faculty of Engineering and Information Sciences - Papers: Part A

We characterise quasidiagonality of the C*-algebra of a cofinal k-graph in terms of an algebraic condition involving the coordinate matrices of the graph. This result covers all simple k-graph C*-algebras. In the special case of cofinal 2-graphs we further prove that AF-embeddability, quasidiagonality and stable finiteness of the 2-graph algebra are all equivalent.

Primary Healthcare System Of Pakistan: Challenges To Self-Management Of Type 2 Diabetes, Rashid M. Ansari, Hassan Hosseinzadeh, Nicholas Arnold Zwar

Faculty of Social Sciences - Papers (Archive)

This review article is aimed at describing the primary healthcare system of Pakistan and its challenges in the face of epidemic of type 2 diabetes, focusing particularly on the middle-aged population of rural area of Pakistan. The main concern in Pakistan is that its middle-aged population is facing the onslaught of obesity and overweight due to lack of physical activity. In addition unhealthy eating habits making it more difficult for this population to control their weight. All these factors are contributing to a high risk of type 2 diabetes for the population of Pakistan. This article provides insight into the …

Segregation Of A Latent High Adiposity Phenotype In Families With A History Of Type 2 Diabetes Mellitus Implicates Rare Obesity-Susceptibility Genetic Variants With Large Effects In Diabetes-Related Obesity, Arthur B. Jenkins, Marijka Batterham, Dorit Samocha-Bonet, Katherine Tonks, Jerry R. Greenfield, Lesley V. Campbell

Dr Marijka Batterham

Background We recently reported significantly greater weight gain in non-diabetic healthy subjects with a 1st degree family history (FH+) of type 2 diabetes mellitus (T2DM) than in a matched control group without such history (FH−) during voluntary overfeeding, implying co-inheritance of susceptibilities to T2DM and obesity. We have estimated the extent and mode of inheritance of susceptibility to increased adiposity in FH+. Methods Normoglycaemic participants were categorised either FH+ (≥1 1st degree relative with T2DM, 50F/30M, age 45±14 (SD) yr) or FH− (71F/51M, age 43±14 yr). Log-transformed anthropometric measurements (height, hip and waist circumferences) and lean, bone and fat mass …

A Residue Formula For The Fundamental Hochschild 3-Cocycle For Suq(2), Ulrich Krahmer, Adam Rennie, Roger Senior

Associate Professor Adam Rennie

An analogue of a spectral triple over SUq(2) is constructed for which the usual assumption of bounded commutators with the Dirac operator fails. An analytic expression analogous to that for the Hochschild class of the Chern character for spectral triples yields a non-trivial twisted Hochschild 3-cocycle. The problems arising from the unbounded commutators are overcome by defining a residue functional using projections to cut down the Hilbert space.

Terahertz Spectroscopy Of 2,4-Dinitrotoluene Over A Wide Temperature Range (7−245 K), Lucia Lepodise, Josip Horvat, R A. Lewis

Faculty of Engineering and Information Sciences - Papers: Part A

Previous THz spectroscopy of the TNT explosive precursor, 2,4-dinitrotoluene (DNT), has been restricted to room temperature (apart from one set of data at 11 K). Here, for the first time, we investigate the spectrum as the temperature is systematically varied, from 7 to 245 K. Many new features appear in the spectrum on cooling below room temperature. As well as the five absorption lines observed previously, we observe five additional lines. In addition, a new room-temperature line at 8.52 THz (281 cm−1) is observed. Six of the lines red-shift with temperature and four of them blue-shift. The blue shift is …

In-Arrears Interest Rate Derivatives Under The 3/2 Model, Joanna M. Goard

Faculty of Engineering and Information Sciences - Papers: Part A

Lie symmetry methods are used to find a closed form solution for in-arrears swaps under the 3/2 model ( ( ) ) ˆ 3 dr = r A t −α r dt + cr 2dZ . As well, approximate solutions are found for short-tenor inarrears caplets and floorlets under the same interest rate model. Comparisons are made of the approximate option values with those obtained with a computationally-intensive numerical scheme. The approximate pricing is found to be substantially fast easy to implement, while the relative errors with respect to the “true” prices are very small.

Boundary C^{2,\Alpha} Estimates For Monge-Ampere Type Equations, Yong Huang, Feida Jiang, Jiakun Liu

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we obtain global second derivative estimates for solutions of the Dirichlet problem of certain Monge-Ampère type equations under some structural conditions, while the inhomogeneous term is only assumed to be Hölder continuous and bounded away from zero and infinity. These estimates correspond to those for the standard Monge-Ampère equation obtained by Trudinger and Wang (2008) and by Savin (2013), and have natural applications in optimal transportation and prescribed Jacobian equations.

On Asymptotic Behaviour And W 2, P Regularity Of Potentials In Optimal Transportation, Jiakun Liu, Neil Trudinger, Xu-Jia Wang

Faculty of Engineering and Information Sciences - Papers: Part A

© 2014, Springer-Verlag Berlin Heidelberg. In this paper we study local properties of cost and potential functions in optimal transportation. We prove that in a proper normalization process, the cost function is uniformly smooth and converges locally smoothly to a quadratic cost x · y, while the potential function converges to a quadratic function. As applications we obtain the interior W2, p estimates and sharp C1, α estimates for the potentials, which satisfy a Monge–Ampère type equation. The W2, p estimate was previously proved by Caffarelli for the quadratic transport cost and the associated standard Monge–Ampère equation.

Shi Xue Dou

Sodium-ion batteries can be the best alternative to lithium-ion batteries, because of their similar electrochemistry, nontoxicity, and elemental abundance and the low cost of sodium. They still stand in need of better cathodes in terms of their structural and electrochemical aspects.

Alternative Al Production Methods: Part 2 - Thermodynamic Analyses Of Indirect Carbothermal Routes, M A. Dewan, M A. Rhamdhani, G A. Brooks, B J. Monaghan, L Prentice

Brian Monaghan

It has been widely claimed that direct and indirect carbothermic reduction of alumina for the production of aluminium have the potential to consume less energy, generate fewer perfluorocarbons and have lower total greenhouse gas emissions compared to the Hall-He´ roult process. A review of alternative aluminium production techniques focusing on the indirect carbothermal reduction routes has been presented in the Part 1 paper. In this Part 2 paper, systematic thermodynamic analyses of indirect carbothermal reduction routes are presented. These include the analyses of the Stage 1 of the process where alumina is converted to intermediate aluminium compounds before they are …

Reliability And Validity Of A Short Ffq For Assessing The Dietary Habits Of 2-5-Year-Old Children, Sydney, Australia, Victoria Flood, Li Ming Wen, Louise Hardy, Chris Rissel, J Simpson, Louise Baur

Hep-2 Cell Image Classification With Multiple Linear Descriptors, Lingqiao Liu, Lei Wang

Faculty of Engineering and Information Sciences - Papers: Part A

The automatic classification of the HEp-2 cell stain patterns from indirect immunofluorescence images has attracted much attention recently. As an image classification problem, it can be well solved by the state-of-the-art bag-of-features (BoF) model as long as a suitable local descriptor is known. Unfortunately, for this special task, we have very limited knowledge of such a descriptor. In this paper, we explore the possibility of automatically learning the descriptor from the image data itself. Specifically, we assume that a local patch can be well described by a set of linear projections performed on its pixel values. Based on this assumption, …

Synthesis And Anti-Leukaemic Activity Of Pyrrolo[3,2,1-Hi]Indole-1,2- Diones, Pyrrolo[3,2,1-Ij]Quinoline-1,2-Diones And Other Polycyclic Isatin Derivatives, Lidia Matesic, Julie M. Locke, Kara Vine, Marie Ranson, John B. Bremner, Danielle Skropeta

Danielle Skropeta

To further expand the structure–cytotoxic activity relationships of isatin derivatives and to reduce flexibility in substituent groups at nitrogen, 20 analogues incorporating a ring system between the N1 and C7 atoms of isatin were prepared using a variety of synthetic strategies. This yielded pyrroloindole-, pyrroloquinoline-, pyrroloacridine-, pyrrolophenanthridine- and benzopyrrolophenanthridine-based systems with embedded isatin moieties, the latter possessing a novel carbon skeleton. These compounds were subsequently assessed for their in vitro cytotoxicity against human U937 lymphoma cells, with the brominated pyrroloacridine dione 27 showing the most promising activity (IC50 3.01 μM) after 24 h.

Spectral Flow Invariants And Twisted Cyclic Theory For The Haar State On Suq(2), A L. Carey, A Rennie, K Tong

Associate Professor Adam Rennie

In [A.L. Carey, J. Phillips, A. Rennie, Twisted cyclic theory and an index theory for the gauge invariant KMS state on Cuntz algebras. arXiv:0801.4605], we presented a K-theoretic approach to finding invariants of algebras with no non-trivial traces. This paper presents a new example that is more typical of the generic situation. This is the case of an algebra that admits only non-faithful traces, namely SUq.2/ and also KMS states. Our main results are index theorems (which calculate spectral flow), one using ordinary cyclic cohomology and the other using twisted cyclic cohomology, where the twisting comes from the generator of …

Marrying Out Part 2- Between Two Worlds, Siobhan Mchugh

Siobhan McHugh

MARRYING OUT: a documentary radio series about mixed marriage and religious bigotry: 2 x 55mins A woman is denied a deathbed visit to her father. A couple’s honeymoon vehicle is sabotaged. A man is cut out of three wills. Children practise their faith in secret. A quarter of the population is barred from applying for jobs. The cause: religion. The place: Australia. The time: until the 1960s. Just two generations ago, before multiculturalism was the norm, Australian society was polarised between two groups: Protestants and Catholics. Religion was code for identity, with tensions fuelled by historical grievances that dated back …

Concerted Ho2 Elimination From Alpha-Aminoalkylperoxyl Free Radicals: Experimental And Theoretical Evidence From The Gas-Phase Nh2 Chco2 - + O2 Reaction, Gabriel Da Silva, Benjamin Kirk, Celli Lloyd, Adam Trevitt, Stephen Blanksby

Adam Trevitt

We have investigated the gas-phase reaction of the α- aminoacetate (glycyl) radical anion (NH2 •CHCO2−) with O2 using ion trap mass spectrometry, quantum chemistry, and statistical reaction rate theory. This radical is found to undergo a remarkably rapid reaction with O2 to form the hydroperoxyl radical (HO2 •) and an even-electron imine (NHCHCO2−), with experiments and master equation simulations revealing that reaction proceeds at the ion−molecule collision rate. This reaction is facilitated by a low-energy concerted HO2 • elimination mechanism in the NH2CH(OO•)CO2− peroxyl radical. These findings can explain the widely observed free-radical-mediated oxidation of simple amino acids to amides …

Gas-Phase Reactions Of Aryl Radicals With 2-Butyne: An Experimental And Theoretical Investigation Employing The N-Methyl-Pyridinium-4-Yl Radical Cation, Adrian Lam, Cong Li, George Khairallah, Benjamin Kirk, Stephen Blanksby, Adam Trevitt, Uta Wille, Richard O'Hair, Gabriel Da Silva

Adam Trevitt

Aromatic radicals form in a variety of reacting gas-phase systems, where their molecular weight growth reactions with unsaturated hydrocarbons are of considerable importance. We have investigated the ion–molecule reaction of the aromatic distonic N-methyl-pyridinium-4-yl (NMP) radical cation with 2-butyne (CH3C≡CCH3) using ion trap mass spectrometry. Comparison is made to high-level ab initio energy surfaces for the reaction of NMP and for the neutral phenyl radical system. The NMP radical cation reacts rapidly with 2-butyne at ambient temperature, due to the apparent absence of any barrier. The activated vinyl radical adduct predominantly dissociates via loss of a H atom, with lesser …

Web 2.0 Adoption And User Characteristics, Jennifer Allyson Dooley, Sandra C. Jones, Donald C. Iverson

Sandra Jones

A literature review and online search were conducted to document the rate of Web 2.0 adoption and to profile user characteristics. Substantial increases over time in reach and growth of the Internet and Web 2.0 by geography, technology, and age were found. Usage of the Internet, blogging, wikis, video sharing, and social networking demonstrates initially high rates among teens and young adults; recent shifts suggest older age categories are now also using Web 2.0. Internet users engage in Web 2.0 for various reasons, such as to seek or create news, entertainment, and even health information. Findings illustrate the potential for …
