Understanding Bulk Behavior Of Particulate Materials From Particle Scale Simulations, Xiaoliang Deng

Dissertations

Particulate materials play an increasingly significant role in various industries, such as pharmaceutical manufacturing, food, mining, and civil engineering. The objective of this research is to better understand bulk behaviors of particulate materials from particle scale simulations.

Packing properties of assembly of particles are investigated first, focusing on the effects of particle size, surface energy, and aspect ratio on the coordination number, porosity, and packing structures. The simulation results show that particle sizes, surface energy, and aspect ratio all influence the porosity of packing to various degrees. The heterogeneous force networks within particle assembly under external compressive loading are investigated …

Engaging Diverse Students In Statistical Inquiry: A Comparison Of Learning Experiences And Outcomes Of Under-Represented And Non-Underrepresented Students Enrolled In A Multidisciplinary Project-Based Statistics Course, Lisa Dierker (Ae), Jalen Alexander, Jennifer L. Cooper, Arielle Selya, Jennifer Rose, Nilanjana Dasgupta

International Journal for the Scholarship of Teaching & Learning

Introductory statistics needs innovative, evidence-based teaching practices that support and engage diverse students. To evaluate the success of a multidisciplinary, project-based course, we compared experiences of under-represented (URM) and non-underrepresented students in 4 years of the course. While URM students considered the material more difficult than non-URM students, URM students demonstrated similar levels of increased confidence in applied skills and interest in follow up courses as non-URM students. URM students were found to be twice as likely as non-URM students to report that their interest in conducting research increased. Increasing student confidence and interest gives all students a welcoming place …

Alternative Representations In Algebraic Problem Solving: When Are Graphs Better Than Equations?, Marta K. Mielicki, Jennifer Wiley

The Journal of Problem Solving

Successful algebraic problem solving entails adaptability of solution methods using different representations. Prior research has suggested that students are more likely to prefer symbolic solution methods (equations) over graphical ones, even when graphical methods should be more efficient. However, this research has not tested how representation format might affect solution success, and whether the efficiency of solution varies depending on the nature of the problem solving task. This study addressed the question of whether symbolic or graphical representation format provides different affordances with respect to two different types of problems: computation and interpretation. Graphical representation was found to facilitate problem …

Research In Brief - Can They Teach Each Other? : The Restructuring Of Higher Education And The Rise Of Undergraduate Student “Teachers” In Ontario, Jennifer Massey, Sean Field

Journal of Critical Scholarship on Higher Education and Student Affairs

Changes to public funding regimes, coupled with transformations in how universities are managed and measured have altered the methods for educating undergraduate students. The growing reliance on teaching fellows, teaching assistants, and increasingly undergraduate peer educators (administering Supplemental Instruction [SI] programs) is promoted as a means toachieve a greater “return on investment” in the delivery of postsecondary education. Neoliberal discourses legitimating this downloading of teaching labour suggest it offers a “win-win” solution to the “problem” of educating growing numbers of undergraduate students. It proposes universities can deliver the same curricula, and achieve the same “outcomes” (primarily measured through grades and …

The Role Of Motivational Systems And Emotions In Virtual Work, Steven A. Murphy, Michael J. Hine, Sandra Kiffin-Petersen Dr

Communications of the IIMA

The purpose of this paper is to examine the role of the behavioural activation system (BAS), the behavioural inhibition system (BIS) and emotions in virtual work. BIS was found to have significant positive relationships with anger, anxiety, annoyance, nervousness, and distress. There were indications of emotional contagion between research confederates and participants. Self-report skill knowledge and the skill role of the research confederate both had significant relationships with performance. Self-report skill knowledge was fully mediated by the skill role played by the research confederate. Managers of virtual teams need to be aware of individual differences such as motivational systems and …

Differential α4(+)/(-)β2 Agonist-Binding Site Contributions To α4β2 Nicotinic Acetylcholine Receptor Function Within And Between Isoforms, Linda M. Lucero, Maegan M. Weltzin, J. Brek Eaton, John F. Cooper, Jon M. Lindstrom, Ronald J. Lukas, Paul Whiteaker

Translational Neuroscience

Two α4β2 nicotinic acetylcholine receptor (α4β2-nAChR) isoforms exist with (α4)2(β2)3 and (α4)2(β2)3 subunit stoichiometries and high versus low agonist sensitivities (HS and LS), respectively. Both isoforms contain a pair of α4(+)/(-)β2 agonist- binding sites. The LS isoform also contains a unique α4(+)/(-)α4 site with lower agonist affinity than the α4(+)/(-)β2 sites. However, the relative roles of the conserved α4(+)/(-)β2 agonist-binding sites in and between the isoforms have not been studied. We used a fully linked subunit concatemeric nAChR approach to express pure populations of HS or LS isoform α4β2∗-nAChR. This approach also allowed us to mutate individual subunit interfaces, or …

Getting Out, Jeff Coussens

2010-2019: All Shows

Released from prison "Arlene" returns to a rundown apartment in Louisville, intent on starting her life over. Rebellious and disruptive as a young girl, she has found strength in religion and wants to put her youth (as "Arlie") behind her. But her struggle to find her way in the present (as "Arlene") is counterpointed by flashbacks of her past (as "Arlie"), her two personalities being represented by two performers, who sometimes appear on stage simultaneously. We meet the guards and prison officials with whom "Arlie" waged a running battle; and the unfeeling, slatternly mother, the lecherous former prison guard, the …

Significance Of Polyphenol Metabolism In Explaining The Bioactivity Of Polyphenol-Rich Foods, Liyang Xie

Doctoral Dissertations

Dietary polyphenols are non-essential phytonutrients that are extensively metabolized upon consumption. We hypothesized that the bioavailability of polyphenol metabolites is more important than unmetabolized polyphenols for the health promoting effects of polyphenol-rich foods. First, we developed a more complete polyphenol profile for almond, by characterizing its extensively metabolized polyphenol composition. In almond, hydrolysable tannin content was 54.7 ± 2.3 mg ellagic acid and 27.4 ± 7.3 mg gallic acid per 100 g almond among varieties. Resveratrol-3-O-glucoside was identified in almond extracts, with 7.19–8.52 μg/100 g almond. Second, we determined the efficiency by which aronia berry polyphenols are metabolized in an …

White-Nose Syndrome Without Borders: Pseudogymnoascus Destructans Infection Tolerated In Europe And Palearctic Asia But Not In North America, Jan Zukal, Hana Bandouchova, Jiri Brichta, Adela Cmokova, Kamil S. Jaron, Miroslav Kolarik, Veronika Kovacova, Alena Kubátová, Alena Nováková, Oleg Orlov, Jiri Pikula, Primož Presetnik, Jurģis Šuba, Alexandra Zahradníková, Natália Martínková

KIP Articles

A striking feature of white-nose syndrome, a fungal infection of hibernating bats, is the difference in infection outcome between North America and Europe. Here we show high WNS prevalence both in Europe and on the West Siberian Plain in Asia. Palearctic bat communities tolerate similar fungal loads of Pseudogymnoascus destructans infection as their Nearctic counterparts and histopathology indicates equal focal skin tissue invasiveness pathognomonic for WNS lesions. Fungal load positively correlates with disease intensity and it reaches highest values at intermediate latitudes. Prevalence and fungal load dynamics in Palearctic bats remained persistent and high between 2012 and 2014. Dominant haplotypes …

Predator Diet And Trophic Position Modified With Altered Habitat Morphology, Alexander Tewfik, Susan S. Bell, Kevin S. Mccann, Kristina Morrow

Integrative Biology Faculty and Staff Publications

Empirical patterns that emerge from an examination of food webs over gradients of environmental variation can help to predict the implications of anthropogenic disturbance on ecosystems. This “dynamic food web approach” is rarely applied at the coastal margin where aquatic and terrestrial systems are coupled and human development activities are often concentrated. We propose a simple model of ghost crab (Ocypode quadrata) feeding that predicts changing dominant prey (Emerita talpoida, Talorchestia sp., Donax variablis) along a gradient of beach morphology and test this model using a suite of 16 beaches along the Florida, USA coast. …

The Grass Is Not Always Greener: Congressional Dysfunction, Executive Action, And Climate Change In Comparative Perspective, Hari M. Osofsky, Jacqueline Peel

Chicago-Kent Law Review

Partisan climate change politics, paired with a legislative branch that is often deeply divided between two parties, has led to congressional gridlock in the United States. Numerous efforts at passing comprehensive climate change legislation have failed, and little prospect exists for such legislation in the foreseeable future. As a result, executive action under existing federal environmental statutes—often in interaction with litigation—has become the primary mechanism for national-level regulation of greenhouse gas emissions from motor vehicles and power plants.

Although many observers critique this state of affairs and wish for a legislature more able to act, this essay argues that more …

Chao Yuanfang: Imperial Physician Of The Sui Dynasty And An Early Pertussis Observer?, Yan Liang, Abdulbaset M. Salim, Wendy Wu, Paul E. Kilgore

Department of Pharmacy Practice

Early Chinese texts contain extensive disease descriptions, including various texts that contain descriptions of modernday conditions. During the Sui Dynasty, a leading scholar, Chao Yuanfang, may have authored a leading treatise 1400 years ago. Although these texts are the subject of ongoing research, evidence suggests that a clinical syndrome consistent with pertussis was observed in ancient China.
