Older Australians Can Achieve High Adherence To The Mediterranean Diet During A 6 Month Randomised Intervention; Results From The Medley Study, Courtney Davis, Jonathan M. Hodgson, Janet Bryan, Manohar Garg, Richard Woodman, Karen Murphy

Research outputs 2014 to 2021

Adherence to a Mediterranean diet (MedDiet) is thought to be achievable in non-Mediterranean regions, but this has yet to be investigated. We aimed to determine if an older Australian population could adhere to a MedDiet for six months. We conducted a randomised, parallel dietary intervention trial with two dietary arms: the Mediterranean diet (MedDiet) group and the habitual diet (HabDiet) control group. A 15-point Mediterranean diet adherence score and food and nutrient intakes were estimated from three-day weighed food records collected at baseline, two and four months. Erythrocyte fatty acids, serum carotenoids and urinary metabolites were assessed at baseline, three …

Prevalence And Molecular Epidemiology Of Clostridium Difficile Infection In Indonesia, Deirdre Collins, M. H. Gasem, T. H. Habibie, I. G. Arinton, P. Hendriyanto, A. P. Hartana, T. V. Riley

Research outputs 2014 to 2021

Clostridium difficile has not been studied in detail in Asia, particularly Southeast Asia. We thus performed a prevalence study across four hospitals in Central Java province, Indonesia. Stool samples were collected from patients with diarrhoea and tested by enzyme immunoassay for glutamate dehydrogenase (GDH) and toxin A/B (C DIFF QUIK CHEK COMPLETE, TechLab). Specimens were cultured and molecular typing was performed. In total, 340 samples were tested, of which 70 (20.6%) were GDH positive, with toxin detected in 19 (5.6%). Toxigenic C. difficile was isolated from 37 specimens (10.9%), while a further 36 (10.6%) nontoxigenic isolates were identified. The most …

Seagrass Halophila Ovalis Is Affected By Light Quality Across Different Life History Stages, Simone Strydom, Kathryn Mcmahon, Gary A. Kendrick, John Stratton, Paul Lavery

Research outputs 2014 to 2021

Seagrass meadows provide crucial ecosystem services to the coastal zone but are threatened globally. Seagrass loss to date has mainly been attributed to anthropogenic activities that reduce light quantity (amount of photosynthetic photon flux density), such as dredging, flooding and eutrophication. However, light quality (wavelengths of light within the visible spectrum) is also altered by these anthropogenic stressors. This study addressed the effect of light quality changes on seagrasses. Aquarium-based experiments were conducted to determine whether the seagrass Halophila ovalis (R.Br.) Hook f. responds to different light quality treatments. Separate experiments were performed in which adults, seeds or seedlings were …

Sirt1 Activation Mediates Heat-Induced Survival Of Uvb Damaged Keratinocytes, Leslie Calapre, Elin S. Gray, Sandrine Kurdykowski, Anthony David, Pascal Descargues, Mel R. Ziman Dr

Research outputs 2014 to 2021

Background

Exposure to heat stress after UVB irradiation induces a reduction of apoptosis, resulting in survival of DNA damaged human keratinocytes. This heat-mediated evasion of apoptosis appears to be mediated by activation of SIRT1 and inactivation of p53 signalling. In this study, we assessed the role of SIRT1 in the inactivation of p53 signalling and impairment of DNA damage response in UVB plus heat exposed keratinocytes.

Results

Activation of SIRT1 after multiple UVB plus heat exposures resulted in increased p53 deacetylation at K382, which is known to affect its binding to specific target genes. Accordingly, we noted decreased apoptosis and …

Hopeful Monsters - In Defense Of Quests To Rediscover Long-Lost Species, David M. Watson, Robert A. Davis

Research outputs 2014 to 2021

Wild goose chase, snipe hunt, fool’s errand—these retorts typify responses of many biologists to news that someone is searching for a species considered extinct. Although these ventures can damage reputations and may offer false hope regarding the finality of extinction, genuine conservation gains often result, even for those quests that prove unsuccessful. As well as enhanced protection for regions where rediscovered species persist and new information of direct management relevance for co-occurring species, well-planned searches for long-lost species represent valuable engagement opportunities to raise awareness in the wider community about biodiversity conservation and science generally. Indeed, we suggest that “Lazarus …

Pso Algorithm For An Optimal Power Controller In A Microgrid, Waleed Al-Saedi, Stefan Lachowicz, Daryoush Habibi, Octavian Bass

Research outputs 2014 to 2021

This paper presents the Particle Swarm Optimization (PSO) algorithm to improve the quality of the power supply in a microgrid. This algorithm is proposed for a real-time selftuning method that used in a power controller for an inverter based Distributed Generation (DG) unit. In such system, the voltage and frequency are the main control objectives, particularly when the microgrid is islanded or during load change. In this work, the PSO algorithm is implemented to find the optimal controller parameters to satisfy the control objectives. The results show high performance of the applied PSO algorithm of regulating the microgrid voltage and …

Drilling Reconfigurable Machine Tool Selection And Process Parameters Optimization As A Function Of Product Demand, Ana Vafadar, Kevin Hayward, Majid Tolouei-Rad

Research outputs 2014 to 2021

Special purpose machines (SPMs) are customized machine tools that perform specific machining operations in a variety of production contexts, including drilling-related operations. This research investigates the effect of optimal process parameters and SPM configuration on the machine tool selection problem versus product demand changes. A review of previous studies suggests that the application of optimization in the feasibility analysis stage of machine tool selection has received less attention by researchers. In this study, a simulated model using genetic algorithm is proposed to find the optimal process parameters and machine tool configuration. During the decision-making phase of machine tool selection, unit …

Insulin Resistance Is Associated With Reductions In Specific Cognitive Domains And Increases In Csf Tau In Cognitively Normal Adults, Simon M. Laws, Scott Gaskin, Amy Woodfield, Velandai K. Srikanth, David G. Bruce, Paul E. Fraser, Tenielle Porter, Philip N. Newsholme, Nadeeja Wijesekara, Samantha C. Burnham, Vincent Doré, Qiaoxin Li, Paul T. Maruff, Colin L. Masters, Stephanie R. Rainey-Smith, Christopher C. Rowe, Olivier Salvado, Victor L. Villemagne, Ralph N. Martins, Giuseppe Verdile

Research outputs 2014 to 2021

Growing evidence supports the hypothesis that type 2 diabetes (T2D) increases the risk of developing dementia. Experimental evidence from mouse models demonstrates that the induction of T2D/insulin resistance (IR) can promote the accumulation of Alzheimer's disease (AD) pathological features. However, the association of T2D with pathological and clinical phenotypes in humans is unclear. Here we investigate the relationship of indices of IR (HOMA-IR) and pancreatic β-cell function (HOMA-B) with cognitive performance across several domains (Verbal/Visual Episodic Memory, Executive Function, Language and a measure of Global cognition) and AD biomarkers (CSF Aβ42, T-tau/P-tau, hippocampal volume and neocortical Aβ-amyloid burden). We reveal …

Clostridium Difficile Infection In The Lao People's Democratic Republic: First Isolation And Review Of The Literature, Elaine Cheong, Tamalee Roberts, Sayaphet Rattanavong, Thomas V. Riley, Paul N. Newton, David A.B. Dance

Research outputs 2014 to 2021

Background

Current knowledge of the epidemiology of Clostridium difficile infection in Asia, and in particular the Greater Mekong Subregion, is very limited. Only a few studies from Thailand and Vietnam have been reported from the region with variable testing methods and results, and no studies from Lao People’s Democratic Republic (PDR). Therefore we investigated the presence of C. difficile in a single centre in the Lao PDR and determined the ribotypes present.

Method

Seventy unformed stool samples from hospital inpatients at Mahosot Hospital, Vientiane, were tested for the presence of C. difficile using selective differential agar and confirmed by latex …

Fretting Wear Behaviors Of Aluminum Cable Steel Reinforced (Acsr) Conductors In High-Voltage Transmission Line, Xingchi Ma, Lei Gao, Junxi Zhang, Laichang Zhang

Research outputs 2014 to 2021

This work reports the fretting wear behavior of aluminum cable steel reinforced (ACSR) conductors for use in high-voltage transmission line. Fretting wear tests of Al wires were conducted on a servo-controlled fatigue testing machine with self-made assistant apparatus, and their fretting process characteristics, friction force, wear damage, and wear surface morphology were detailed analyzed. The results show that the running regime of Al wires changes from a gross slip regime to a mixed regime more quickly as increasing contact load. With increasing amplitudes, gross slip regimes are more dominant under contact loads of lower than 30 N. The maximum friction …

Research outputs 2014 to 2021

Introduction

The findings of three recent phenomenographic studies conducted by a practitioner-researcher team (the information literacy experiences of English as a foreign language (EFL) students, how international branch campus faculty members experience the academic library and the open access experiences of faculty members in online education) are analysed to discover what practical implications were revealed from the categories of description that can be used in practice.

Method

Meta-analysis of the categories of description of three phenomenographic studies was conducted.

Analysis

Categories of description were analysed iteratively in order to identify which library services and processes could be informed by the …

The Panopticon Kitchen: The Materiality Of Parental Surveillance In The Family Home, Donell Holloway

Research outputs 2014 to 2021

This article examines the production and performance of parental surveillance of children’s internet activities within the family home. Through an analysis of qualitative interviews in the family homes of children aged from five to twelve years, the manner in which parents are positioned as ‘instruments of surveillance’ and the materiality of this surveillance are discussed. Parents’ worldly surveillance of their younger children’s internet use in Australian family homes can often be likened to Foucault’s panopticon, where the site of central inspection is often the family kitchen. This is because the physical positioning of spatial dimensions in the standard Australian home …

Ethnographic Insights Into Safety Communication For Frontline Workers, Kelly Jaunzems, Lelia Green, David Leith, Christine Teague

Research outputs 2014 to 2021

Recent calls for organisation studies to embrace ‘the practice turn’ (Whittington, 2011) have expanded into an understanding of the potential for ethnographic research in occupational health and safety (OHS) research (Pink et al., 2016). The ethnographic project described here, with fieldwork conducted between 2008 and 2010, is one element of this growing appreciation of the potential for qualitative research in industrial settings. Ethnographies have not often been used in OHS settings, and ‘much practicebased knowledge remains undocumented, informal, unspoken and thus unaccounted for’ (Pink et al., 2016, p. 27). This study was motivated by an aim to make explicit the …

The purpose of the study was to examine existing literature related to the involvement of parents of urban middle and high school students and its impact on academic success.

The research method used in this study was a systematic review of the literature following the protocol outlined by the Campbell Collaboration …

A Newly Discovered Letter Of 1827 By Fernando Sor, Erik Stenstadvold

Soundboard Scholar

This article discusses a hitherto unknown letter, written by Sor in Saint Petersburg in April 1827. It provides new insight into the publishing and personal relationship between Sor and his Paris publisher, Antoine Meissonnier, to whom the letter was addressed. We learn about three airs with variations Sor was busy composing at the time; he was particularly pleased with the variations Meissonnier later published as op. 30. The letter also mentions some unknown Sor works, including a book of drafts at Málaga, and it reveals that Meissonnier had published, without Sor’s knowledge, music that he had received from sources other …

AndréS Segovia’S Unfinished Guitar Method: Placing His “Scales” In Historical Context, Andreas Stevens

Soundboard Scholar

For over sixty years, guitarists of my generation have been familiar with the so-called Segovia Scales—the systematic scale fingerings advocated by the Andalusian maestro. They have been an influential—some might say a definitive—bestseller since their first USA publication in 1953. Countless guitar students have incorporated them into their daily practice routines. For the publisher, Columbia Music, they seem to be the goose that laid the golden egg. Are they everything that Segovia wanted them to be? Two books of recent date on guitar technique attest to their enduring value and relevance. Thomas Offermann wrote in 2015: “The fingerings of the …

Guitar Music In Collections: A New Web-Based Index Is Launched, Ellwood Colahan

Soundboard Scholar

Is there any really good way to locate specific pieces of guitar music within published collections and anthologies? Might there be already a best way? Anyone who has taught or studied classical guitar is familiar with collections like Das Gitarrespiel or the Noad anthologies. But it is hard to remember with accuracy which pieces are in which of these editions or in dozens of others like them. Library and trade catalogs are not of much help. What is needed for this problem is in-depth indexing rather than traditional cataloging. These print indexes of song anthologies and collections have more recently …
