Dr Marijka Batterham
Several regulatory bodies have approved a health claim on the cholesterol-lowering effects of oat β-glucan at levels of 3·0 g/d. The present study aimed to test whether 1·5 g/d β-glucan provided as ready-to-eat oat flakes was as effective in lowering cholesterol as 3·0 g/d from oats porridge. A 6-week randomised controlled trial was conducted in eighty-seven mildly hypercholesterolaemic ( ≥ 5 mmol/l and < 7·5 mmol/l) men and women assigned to one of three diet arms (25 % energy (E%) protein; 45 E% carbohydrate; 30 E% fat, at energy requirements for weight maintenance): (1) minimal β-glucan (control); (2) low-dose oat β-glucan …

The performance of two redox mediating compounds, namely 1-hydroxybenzotriazole (HBT) and syringaldehyde (SA), was compared in terms of enhancement of enzymatic degradation of a diverse set of 14 phenolic and 16 non-phenolic trace organic contaminants (TrOCs) and the toxicity of the treated media. Extracellular enzyme extract (predominantly containing laccase) from Trametes versicolor culture achieved efficient degradation (70-95%) of nine phenolic and one non-phenolic TrOCs. Mediator dosing extended the spectrum of efficiently degraded TrOCs to 13 phenolic and three non-phenolic compounds, with moderate improvements in removal of a few other non-phenolic compounds. TrOC removal efficiency improved significantly as the HBT dose …

Effects And Measures Of Technostress Among Librarians In Selected University Libraries Of Delhi, Mayank Yuvaraj Dr., Amarjit Kumar Singh
Library Philosophy and Practice (e-journal)
Technology is a mobile and integral part of many work places, and computers and other information and communication technology have made many users’ work life easier, but technology can also contribute to problems in the cognitive work environment and, over time, create technostress. Much previous research on technostress has focused on the use of digital technology and its effects, measured by questionnaires. This paper applies a distributed cognition perspective to human–technology interaction, investigated through Limesurvey to examine technostress, its effects and measures taken to avoid it among librarians at university libraries in Delhi. About 200 library professionals participated in the …
The Impact Of Exchange Rate Fluctuations On Labor Migration: Evidence From U.S. Nonimmigrant Visa Statistics, Yaqi Gao
Honors Theses
Since mid-20th century, international migration has become a widespread phenomenon in nearly all industrialized countries and a major shaping force of the international labor market. Most economic theories consider labor migration to be an investment of human capital where workers seek to maximize household income and minimize financial risks. Because exchange rate changes affect prospective income and financial risks associated with migration, studying the responsiveness of skilled migrants to exchange rate fluctuations contribute to the studies of labor economics and international economics. This paper further investigates whether an appreciation in U.S. dollars incentivizes both skilled and unskilled workers to migrate …
The Effect Of A Class-Wide Training On Prosocial Bystander Behaviors, Charity Deanne Barnes
The Effect Of A Class-Wide Training On Prosocial Bystander Behaviors, Charity Deanne Barnes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study was to decrease school bullying by teaching defending steps and increasing incentives for bystanders, students who witness bullying but who are not necessarily involved in the violence. An established bullying prevention program was modified to increase the likelihood that bystanders would defend victims of bullying behaviors. The findings of the study suggested that bullying behavior decreased and defending increased. Further, acceptability of the intervention and the skills taught to children were rated as moderately high across all classrooms.

Atmospheric deposition represents a major input of mercury to surface environments. The phase of mercury (gas or particle) has important implications for its removal from the atmosphere. We use long-term observations of reactive gaseous mercury (RGM), particle-bound mercury (PBM), fine particulate matter (PM2.5), and temperature at five sites in North America to derive an empirical gas-particle partitioning relationship log10(K-1) = (10 ± 1) − (2500 ± 300)/T where K = (PBM/PM2.5)/RGM with PBM and RGM in common mixing ratio units, PM2.5 in μg m−3, and T in Kelvin. This relationship is in the range of previous work but is based …

Recently, there has been an increased interest in imaging different pulmonary disorders using PET techniques. Previous work has shown, for static PET/CT, that air content in the lung influences reconstructed image values and that it is vital to correct for this 'tissue fraction effect' (TFE). In this paper, we extend this work to include the blood component and also investigate the TFE in dynamic imaging. CT imaging and PET kinetic modelling are used to determine fractional air and blood voxel volumes in six patients with idiopathic pulmonary fibrosis. These values are used to illustrate best and worst case scenarios when …

Faculty of Engineering and Information Sciences - Papers: Part A
As twinning-induced plasticity (TWIP) steel is one potential material for shaped charge liner due to the combination of high strength and high plasticity, deformation mechanism at high strain rate and high temperature is required to study. Compression experiments of Fe-30Mn-3Si-4Al TWIP steel were conducted using a Gleeble-1500 thermal simulation machine and a split-Hopkinson pressure bar (SHPB) between 298 and 1073 K at strain rates of 10-3 and 700 s-1, respectively. Microstructures were observed using optical microscopy (OM) and transmission electron microscopy (TEM). Results show that flow stress and densities of deformation twins and dislocations decrease with increasing deformation temperature at …

Grain Size Effect Of Thickness/Average Grain Size On Mechanical Behaviour, Fracture Mechanism And Constitutive Model For Phosphor Bronze Foil, Zhi Fang, Zhengyi Jiang, Xiaogang Wang, Cunlong Zhou, Dongbin Wei, Xianghua Liu
Faculty of Engineering and Information Sciences - Papers: Part A
Size effects play a significant role in microforming process, and any dimensional change can have a great impact on materials' mechanical properties. In this paper, the size effects on deformation behaviour and fracture of phosphor foil were investigated in the form of grain size effect: the ratio of materials' thickness (T) to average grain size (D) by micro tensile tests. The ratio was designed to be closed to but larger than, less than and equal to 1, respectively. The results show that the amount of plastic deformation decreases with the decrease of the ratio of T/D, which indicates that the …
The Bulk-Edge Correspondence For The Quantum Hall Effect In Kasparov Theory, Christopher J. Bourne, Alan L. Carey, Adam C. Rennie
The Bulk-Edge Correspondence For The Quantum Hall Effect In Kasparov Theory, Christopher J. Bourne, Alan L. Carey, Adam C. Rennie
Faculty of Engineering and Information Sciences - Papers: Part A
We prove the bulk-edge correspondence in K-theory for the quantum Hall effect by constructing an unbounded Kasparov module from a short exact sequence that links the bulk and boundary algebras. This approach allows us to represent bulk topological invariants explicitly as a Kasparov product of boundary invariants with the extension class linking the algebras. This paper focuses on the example of the discrete integer quantum Hall effect, though our general method potentially has much wider applications.

High-speed steel (HSS) materials are universally used as work rolls for the hot rolling of stainless steels. Their use has increased the output of the rolling mill and decreased roll material consumption and grinding. Sticking defects often occur, however, during the hot rolling process. In this article, extreme pressure (EP) additives were dropped on the HSS samples at high temperature. Zinc dialkyl dithiophosphate (ZDDP) was chosen as the most effective EP additive by scratch tests on the HSS samples. In order to determine the optimum proportion of ZDDP in the lubricant, two reduction rates were tested on a Hille 100 …

The Effect Of Nb On The Continuous Cooling Transformation Curves Of Ultra-Thin Strip Castrip© Steels, Kristin R. Carpenter, Chris R. Killmore
Faculty of Engineering and Information Sciences - Papers: Part A
The effect of Nb on the hardenability of ultra-thin cast strip (UCS) steels produced via the unique regime of rapid solidification, large austenite grain size, and inclusion engineering of the CASTRIP© process was investigated. Continuous cooling transformation (CCT) diagrams were constructed for 0, 0.014, 0.024, 0.04, 0.06 and 0.08 wt% Nb containing UCS steels. Phase nomenclature for the identification of lower transformation product in low carbon steels was reviewed. Even a small addition of 0.014 wt% Nb showed a potent effect on hardenability, shifting the ferrite C-curve to the right and expanding the bainitic ferrite and acicular ferrite phase …

Effect Of Mesh On Springback In 3d Finite Element Analysis Of Flexible Microrolling, Feijun Qu, Zhengyi Jiang, Haina Lu
Faculty of Engineering and Information Sciences - Papers: Part A
In flexible microrolling, springback in thickness direction is a critical indicator to determine the forming quality. Accurate prediction of springback is one of the significant aspects in the finite element analysis of flexible microrolling. Meshing is a step of great importance in finite element analysis of manufacturing process as it directly determines the accuracy of the FEA results as well as the requested computational time. This paper presents a numerical study on revealing the mesh effects on the accuracy of springback estimation utilising ABAQUS/Standard for modelling and analyses. Two types of meshes with six mesh sizes for each mesh type …

Faculty of Engineering and Information Sciences - Papers: Part A
A refined microstructure consisting of martensite and retained austenite at room temperature has been produced in a Nb-microalloyed low carbon Si-Mn steel by a novel heat-treatment, pre-quenching prior to quenching and partitioning processes (Q&Q-P). The results showed that compared with the conventional quenching and partitioning steel the mechanical properties of steel obtained by the novel treatment have been significantly improved, with a good combination of ultimate tensile strength (1000MPa) and total elongation (above 30%). Meanwhile, the volume fraction of retained austenite has been increased. It was found that the improvement of mechanical properties was mainly attributed to the enhanced TRIP …

Effects Of Mild To Moderate Stress On Mental Rotation, James Frederick Bell
Effects Of Mild To Moderate Stress On Mental Rotation, James Frederick Bell
Walden Dissertations and Doctoral Studies
Mental rotation (MR) is the ability to mentally shift one's visual perspective of any object by changing the orientation of a mental image of that object. Research into the effects of stress on MR could be used to help improve understanding of a variety of visual-spatial tasks performed in hyper-vigilance situations. However, until the present study, there has been no research on the effects of stress on MR. The Yerkes-Dodson Law predicts performance will be improved when an individual is exposed to mild to moderate stress. The purpose of this study was to answer three research questions. The questions examined …
The Syntax-Space Effect, Timothy W. Boiteau
The Syntax-Space Effect, Timothy W. Boiteau
Theses and Dissertations
Previous research has linked the concept of number and other ordinal series to space via a spatially-oriented number line. Other researchers have shown that language as well may have an underlying spatial representation, though this seems to be tied to visual scene recognition and production and is potentially an idiosyncratic effect of a limited set of concrete verbs. In this dissertation, employing a novel method that measures the underlying spatial biases of actors in transitive sentences, I show that findings from previous studies showing a relationship between transitivity and space reflect an interaction between word order in the sentence, order …
