Secondly, at higher Re values (Re > 50), vorticity development around the trailing bubble causes it to deviate away from the inline configuration, thus preventing the occurrence of a head-on collision between the two bubbles. The deviation of the bubble was found occur if a certain critical velocity is exceeded by the trailing bubble. The value of the critical velocity was found to decrease with increasing Re values. Further, an increase in Eotvos number (Eo = ριgD2/σ) tends to increase the critical velocity, indicating that enhanced bubble deformability actually improves the path stability of the trailing bubble.

The study shows that the number of arsenic contaminated samples (and wards) in the southern part of the KMC exceeds that of other parts of the city. The daily intake of arsenic from drinking water was estimated as 0.95 μg per kg bw and the cancer risk was estimated as 1425/106. Analyses of biological samples (hair, nail and urine) showed elevated concentrations of arsenic indicating the presence of subclinical arsenic poisoning, predicting an enhanced lifetime cancer risk for the population in southern part of the KMC. In the KMC, groundwater is not a sustainable source of freshwater due to arsenic, high iron, hardness and total dissolved solids. Its continued use is impelled by the lack of an adequate infrastructure to treat and supply surface water and in some wards the unaccounted for water (UFW) is even >45% incurred during distribution. The rare imposition of a water tax makes the water supply systems unsustainable and fosters indifference to water conservation. To mitigate the arsenic problem, continuous groundwater monitoring for pollutants, a treated surface water supply with strict policy implications, rainwater harvesting in the urban areas and introduction of water taxes seem to be long-term visible solutions.]]> Thu 14 Apr 2022 11:04:28 AEST ]]> Combined interdiffusion and self-diffusion analysis in Al-Cu liquid diffusion couple https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33290 65Cu sandwiched between the interdiffusion couple ends have been performed on liquid Al-Cu that is suitable for demonstration of the application of this analysis.

Participants were 429 schizophrenia/schizoaffective cases from the Australian Schizophrenia Research Bank (ASRB). Cognitive performance was assessed using the Repeatable Battery for Assessment of Neuropsychological Status (RBANS), Controlled Oral Word Association Test (COWAT), Letter Number Sequencing (LNS) test, and the Wechsler Test of Adult Reading (WTAR). Hierarchical regression was used to test the main effects and additive interaction effects of genotype and childhood trauma in the domains of physical abuse, emotional abuse, and emotional neglect, on cognition and symptom profiles of clinical cases. Consistent with previous findings, COMT Val homozygotes performed worse on cognitive measures in the absence of childhood adversity. In addition, a significant interaction between COMT genotype and physical abuse was associated with better executive function in Val homozygotes, relative to those of the same genotype with no history of abuse. Finally, the severity of positive symptoms was greater in Met carriers who had experienced physical abuse, and the severity of negative symptoms in Met carriers was greater in the presence of emotional neglect. These results suggest that the possible epigenetic modulation of the expression of the COMT Val158Met polymorphism and consequent effects on cognition and symptoms in schizophrenia, with worse outcomes associated with adverse childhood experiences in Met carriers.]]> Sat 24 Mar 2018 08:05:04 AEDT ]]> Detachment of particles from bubbles in an agitated vessel https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21418 Sat 24 Mar 2018 08:05:02 AEDT ]]> Identifying individual differences among doctoral candidates: a framework for understanding problematic candidature https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18277 Sat 24 Mar 2018 08:04:24 AEDT ]]> Allopregnanolone in the brain: protecting pregnancy and birth outcomes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16514 Sat 24 Mar 2018 08:04:18 AEDT ]]> Finite element analysis of a micromechanical model of bone and a new 3D approach to validation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20341 Sat 24 Mar 2018 08:02:57 AEDT ]]> Study of thermally conditioned and weak acid-treated serpentinites for mineralisation of carbon dioxide https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20855 Sat 24 Mar 2018 08:02:51 AEDT ]]> Computational Fluid Dynamics (CFD) modelling of transfer chutes: a study of the influence of model parameters https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18738 Sat 24 Mar 2018 08:02:49 AEDT ]]> Retrofitting cities: local governance in Sydney, Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20552 Sat 24 Mar 2018 08:02:40 AEDT ]]> Connecting filtering and control sensitivity functions https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19466 Sat 24 Mar 2018 08:02:23 AEDT ]]> Neuroactive steroids in pregnancy: key regulatory and protective roles in the foetal brain https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16519 Sat 24 Mar 2018 08:01:21 AEDT ]]> Modelling of the interaction between a falling n-heptane droplet and hot solid surface https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20753 Sat 24 Mar 2018 08:00:25 AEDT ]]> Cone penetration-induced pore pressure distribution and dissipation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20477 u), over-consolidation ratio (OCR) and rigidity index (Ir) of the soil.

This is thought to reflect incongruent dissolution of Mg-rich phases. Correction of Sr concentrations for contributions from airborne exogenic Sr, based on 87Sr/86Sr ratios, yields the bedrock-only contribution (Src). Src variation in stalagmite calcite is influenced by speleothem growth rate and by variation of the calcite-water Sr partitioning in wet and dry phases, and only to a minor extent by incongruent dissolution of Mg-rich phases. Concentration profiles for Mgc and Srcg (corrected for growth rate effects) show inverse correlations and are inferred to show hydrological significance which is captured in a hydrological index, HI. We suggest HI provides robust information on water–rock interaction related to hydrological changes and can be utilized in both wet and semi-arid environments, provided the corrections for soil Mg and exogenic Sr can be applied with confidence. Application of the HI index allows correction of Grotta Savi oxygen isotope data, to yield a δ18Oc time series that shows when changes in moisture sources and atmospheric reorganization, or changes in moisture amount, were significant. This is especially evident during the Younger Dryas (YD). The Savi record supports the concept of a two-phase YD, marked by an increase of moisture and stronger impact of Adriatic and Mediterranean Sea influences over the northern Adriatic region from 12.3 ka onwards. Then, a large-scale atmospheric reorganization and gradual northward shift of the Polar Front caused a progressive reduction of sea influence over the region from 12.1 ka, supporting the concept of a hemispheric change.]]> Sat 24 Mar 2018 07:41:31 AEDT ]]> Evaluating the mobility of polymer-stabilised zero-valent iron nanoparticles and their potential to co-transport contaminants in intact soil cores https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30122 Sat 24 Mar 2018 07:37:58 AEDT ]]> Effect of turbulence on particle and bubble slip velocity https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28747 dPD=5–12 mm) and single air bubbles (dB=1–4 mm) has been measured in a solid–liquid fluidized bed of uniform size borosilicate glass beads (dP=5 and 8 mm) as a function of liquid superficial velocity. The homogeneity and intensity of the turbulence within the fluidized bed has been quantified and directly related to the slip velocity of the foreign (steel or bubble) particle. It was found that the turbulence resulted in an increase in the computed drag coefficient for all of the experimental conditions investigated.]]> Sat 24 Mar 2018 07:37:35 AEDT ]]> Mapped infinite patches for the NURBS based boundary element analysis in geomechanics https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26210 Sat 24 Mar 2018 07:36:32 AEDT ]]> Qualitative evolving rockfall hazard assessment for highwalls https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30880 Sat 24 Mar 2018 07:30:37 AEDT ]]> Static spatial descriptions in five Germanic languages https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28910 stands on the table vs. the cup is on the table). The main focus lies on a detailed description of the modalities and proportions of this additional expression of information on the spatial scene in the five languages. Distributed expression of spatial relational semantics, posture verb usage and resultative constructions are analyzed. Descriptive and inferential methods are used to show the similarities and differences across the five languages, on the level of group tendencies (means), of individual speakers, and of individual stimulus items. The analyses show considerable differences across the languages. Speakers of Standard German and Frisian are most prone to integrate additional manner information into the descriptions, whereas speakers of Icelandic, Norwegian or Swiss German only rarely integrate this kind of information into their spatial descriptions.]]> Sat 24 Mar 2018 07:26:00 AEDT ]]> Scheduling network maintenance jobs with release dates and deadlines to maximize total flow over time: bounds and solution strategies https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27960 Mon 23 Sep 2019 11:29:20 AEST ]]> Single-stage recovery and concentration of mineral sands using a REFLUX™ Classifier https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30304 3, with the majority in the size range from 50 to 150 µm. The overall recovery of the heavy minerals component was approximately constant at 85% for solids throughputs of 10-18.5 t/(m2 h). The unrecovered heavy mineral had an average density close to that of the gangue, hence was deemed unrecoverable by gravity separation. The recovery of the denser and more liberated zirconium mineral exceeded 95%. So this work demonstrated the potential for the heavy mineral to be upgraded by a factor of 16 or more in a single stage operation.]]> Mon 23 Sep 2019 11:23:20 AEST ]]> In situ scanning tunneling microscopy (STM), atomic force microscopy (AFM) and quartz crystal microbalance (EQCM) studies of the electrochemical deposition of tantalum in two different ionic liquids with the 1-butyl-1-methylpyrrolidinium cation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22100 5 in two hydrophobic ionic liquids (1-butyl-1-methylpyrrolidinium tris(pentafluoroethyl) trifluorophosphate ([Py1,4]FAP) and 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) amide ([Py1,4]TFSA) is probed using three in situ techniques: scanning tunneling microscopy (STM), atomic force microscopy (AFM), and electrochemical quartz crystal microbalance (EQCM). These techniques reveal that under similar conditions TaF5is more easily reduced in the liquids with [TFSA]− than [FAP]−anions. Increasing the temperature reduced the viscosity and density of the ionic liquids which facilitates TaF5 electroreduction, in particular, in [Py1,4]TFSA. A herringbone reconstruction of the Au electrode was observed by STM for both ionic liquids with and without TaF5. Ta deposition was proved by STM and EQCM in [Py1,4]TFSA. Cracked layers, with ionic liquid trapped inside, were obtained by direct plating from the [TFSA]− ionic liquid.

To solve this problem, a Fenton-like system consisting of nanoscale zero-valent iron (nZVI) and hydrogen peroxide was used for further oxidation of the metabolites after biodegradation. Results showed that the total COD removal increased from 56.8% to 89% under the optimal condition. In addition, effects of initial pH (2.0–9.0), ZVI dosage (0–2.0 g L-1), hydrogen peroxide (H₂O₂) dosage concentration (0–15 mmol L-1) and temperature (298–308 K) on the treatment efficiency of the combined process were studied. Scanning electron microscopy (SEM) demonstrated that changes to the surface of nZVI occurred. GC-MS revealed that the degraded metabolites were mineralized practically by nZVI/H₂O₂ system. The results points towards the potential of Fenton-like oxidation as a short post-treatment after a biological process for the treatment of organic pollutants in wastewater.]]> Fri 17 Nov 2023 11:42:05 AEDT ]]>
