Expectancy in double-blind placebo-controlled trials: An example from alcohol dependence
17 Jan 2019University of SydneyColagiuri, Ben Morley, Kirsten Boakes, Robert A Haber, PaulBackground: Double-blind placebo-controlled trials are intended to control for the impact of expectancy on outcomes. Whether they always achieve this is, however, questionable. Methods: Reanalysis of a clinical trial of naltrexone and acamprosate for alcohol dependence investigated this issue further. In this trial, 169 alcohol dependent patients received naltrexone, acamprosate, or placebo for 1…

Correlations for maximum penetration heights of transitional plane fountains in linearly stratified fluids
20 Dec 2021University of SydneyInam, Mohammad Lin, WenxianIn this study, a series of three-dimensional direct numerical simulations (DNS) were carried out using ANSYS Fluent for transitional plane fountains in linearly stratified fluids with the Reynolds number (Re), Froude number (Fr) and dimensionless temperature stratification parameter (s) over 28 ≤ Re ≤ 300, 3 ≤ Fr ≤ 10, and 0.1 ≤ s ≤ 0.5, to study and quantify the effects of these governing parame…

Variability in practices for drinking water vaccination of meat chickens against infectious laryngotracheitis
27 Sep 2022University of SydneyGroves, Peter J. Assen, Awol M. Etherington, Ashley Stillman, Mark Alfirevich, Sheridan Gerber, Priscilla F. Langfield, Alex-Kate Walkden-Brown, Stephen W.Context: Drinking water vaccination of young meat chickens with Infectious Laryngotracheitis (ILT) vaccine is problematic. Vaccine failure and adverse vaccine reactions are frequently reported. Variations in the technique of applying ILT vaccines by this mass vaccination method need to be understood to contribute to improving the success of vaccination. Aims: This study aimed to examine variation…

A performance comparison of individual and combined treatment modules for water recycling
01 Nov 2010University of EdinburghKhan, Stuart Wintgens, Thomas Sherman, Paul Zaricky, Jan Schäfer, AndreaAn Advanced Water Recycling Demonstration Plant (AWRDP) was commissioned and constructed by the Queensland State Government in Australia. The AWRDP was used to study the effectiveness of a variety treatment processes in the upgrading of municipal wastewater for water recycling applications. The AWRDP consists of eight modules, each housing an individual specific treatment process. These processes…

Adsorption of Estrone on nanofiltration and reverse osmosis membranes in water and wastewater treatment
10 Nov 2010University of EdinburghNghiem, D.L. Schäfer, Andrea Waite, T.D.Adsorption of the trace contaminant estrone, a natural hormone and commonly abundant in surface waters and in treated as well as untreated wastewaters, to eight commercial nanofiltration (NF) and reverse osmosis (RO) membranes was investigated under welldefined conditions. Experiments were conducted in stainless steel stirred cells by spiking trace levels (100ng.L-1) of estrone into five differen…

Physico-chemical water quality in Ghana: Prospects for water supply technology implementation
15 Nov 2010University of EdinburghSchäfer, Andrea Rossiter, H.M.A. Owusu, P.A. Richards, B.S. Awuah, E.During an extensive sampling trial in Ghana, a number of physico-chemical water quality problems have been identified. For example, pH values of the collected samples ranged from 3.69 to 8.88, while conductivity ranged from 10 to 45,000 mS/cm and turbidity from 0 to >542 NTU. Many water samples analysed breached the drinking water quality guidelines. High levels of heavy metals were found and als…

Estrogenic hormone removal from wastewater using NF/RO membranes
16 Nov 2010University of EdinburghNghiem, L.D. Manis, A. Soldenhoff, K. Schäfer, AndreaThis paper investigates the separation process of two estrogenic hormones, estrone and estradiol, using eight commercial NF and low pressure RO membranes. The results indicate that the separation mechanism of estrone and estradiol in membrane filtration processes is similar. While estrogenic hormone retention by porous membranes decreases with decreasing adsorption and the subsequent retention is…

Renewable energy powered membrane technology. 2. The effect of energy fluctuations on performance of a photovoltaic hybrid membrane system
16 Nov 2010University of EdinburghRichards, B.S. Capão, D.P.S. Schäfer, AndreaThis paper reports on the performance fluctuations during the operation of a batteryless hybrid ultrafiltration – nanofiltration / reverse osmosis (UF-NF/RO) membrane desalination system powered by photovoltaics treating brackish groundwater in outback Australia. The renewable energy powered membrane (RE-membrane) system is designed to supply clean drinking water to a remote community of about 50…

System design and performance testing of a hybrid membrane — photovltaic desalination system
16 Nov 2010University of EdinburghMasson, Laurent Richards, B. S. Schäfer, AndreaIn some areas limited water resources combined with the fast growing population are leading to a crucial situation because of the increase in water demand. Besides, an estimated one billion people are living both without access to clean drinking water or electricity. Therefore, a stand alone photovoltaic-power based hybrid membrane desalination prototype has been designed to meet this challenge. …
