Biofilter Media Characterization Using Water Sorption Isotherms, Guilherme Del Nero Maia, George B. Day, Richard S. Gates, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

Compost material has been used extensively as a gas‐phase biofilter media for contaminant gas treatment in recent years. One of the biggest challenges in the use of this type of material is adequate control of compost moisture content and understanding its effect on the biofiltration process. The present work provides a methodology for characterization of biofilter media under low moisture conditions. Results indicated that low levels of equilibrium moisture content (EMC) were obtained for high levels of equilibrium relative humidity (ERH), i.e., 99% ERH produced EMC of approximately 20% (dry basis) at 25° C. Most bacteria struggle to survive in …

Evaluating Mitochondrial Uncoupling Potentials Of A7e And Dnp In Saccharomyces Cerevisiae : Implications For Human Obesity, Roger Vaughan Jul 2011

Evaluating Mitochondrial Uncoupling Potentials Of A7e And Dnp In Saccharomyces Cerevisiae : Implications For Human Obesity, Roger Vaughan

Individual, Family, and Community Education ETDs

Obesity is one of the most prevalent maladies in the United States and is a major cause of preventable death. Weight loss supplements frequently claim uncoupling as a mechanism of action. Uncoupling agents could be used for weight loss because they disrupt mitochondrial metabolism thereby reducing adenosine triphosphate (ATP) yield. Consequently, metabolic efficiency diminishes increasing basal metabolic rate. 2,4-Dinitrophenol (DNP) successfully uncouples but was banned in 1938 because of a narrow window between efficacy and toxicity. PURPOSE: To measure the ability of a blend that reportedly contains 17-dihydroxy-delta-5-etiocholane-7-one and p-methylcarbonylethylphenol and other substances (A7E), a purported uncoupling agent, to interfere …

When Knowing Just Isn't Enough: Examining The Role Of Moral Emotions In Health Decision Making Using The Theory Of Planned Behavior, Kate Duangdao Jul 2011

When Knowing Just Isn't Enough: Examining The Role Of Moral Emotions In Health Decision Making Using The Theory Of Planned Behavior, Kate Duangdao

Department of Psychology: Dissertations, Theses, and Student Research

A proposed integrated Theory of Planned Behavior (TPB) model aimed to examine the role of moral emotions and two health outcomes: prosocial behaviors and smoking outcomes. Based on Tangney’s work with shame and guilt-proneness, it was expected that those more prone to guilt would engage in more prosocial behaviors and those more prone to shame would engage in more smoking behaviors. Prosocial behaviors were found to be negatively associated with smoking outcomes. However, results suggested that guilt and shame-proneness seem to function similarly in predicting behavioral outcomes. Components within the TPB were generally positively correlated with each health outcome, however …

Throwing Precaution To The Wind: Nepa And The Deepwater Horizon Blowout, Sandra B. Zellmer, Joel A. Mintz, Robert Glicksman Jul 2011

Throwing Precaution To The Wind: Nepa And The Deepwater Horizon Blowout, Sandra B. Zellmer, Joel A. Mintz, Robert Glicksman

Faculty Law Review Articles

On April 20, 2010, British Petroleum's ("BP") Deepwater Horizon oil platform exploded, killing eleven workers. When the platform sank to the bottom of the Gulf of Mexico two days later, oil erupted out of the riser-a 5000-foot pipe connecting the platform to the well on the ocean floor. 2 Efforts to stem the flow failed when a safety device, the "blowout preventer," could not be activated.' Finally, after a number of attempts to stop the leak, BP capped the well on July 15.4 Nearly five million barrels of oil were released over the course of eighty-six days, making the Deepwater …

Beyond Structural Genomics: Computational Approaches For The Identification Of Ligand Binding Sites In Protein Structures, Dario Ghersi, Roberto Sanchez Jul 2011

Beyond Structural Genomics: Computational Approaches For The Identification Of Ligand Binding Sites In Protein Structures, Dario Ghersi, Roberto Sanchez

Interdisciplinary Informatics Faculty Publications

t Structural genomics projects have revealed structures for a large number of proteins of unknown function. Understanding the interactions between these proteins and their ligands would provide an initial step in their functional characterization. Binding site identification methods are a fast and cost-effective way to facilitate the characterization of functionally important protein regions. In this review we describe our recently developed methods for binding site identification in the context of existing methods. The advantage of energy-based approaches is emphasized, since they provide flexibility in the identifi- cation and characterization of different types of binding sites

Finite-State Markov Chains Obey Benford’S Law, Arno Berger, Theodore P. Hill, Bahar Kaynar, Ad Ridder Jul 2011

Finite-State Markov Chains Obey Benford’S Law, Arno Berger, Theodore P. Hill, Bahar Kaynar, Ad Ridder

Research Scholars in Residence

A sequence of real numbers(xn)is Benford if the significands, i.e. the fraction parts in the floating-point representation of (xn), are distributed logarithmically. Similarly, a discrete-time irreducible and aperiodic finite-state Markov chain with probability transition matrix P and limiting matrix P* is Benford if every component of both sequences of matrices (Pn −P*)and (P n+1-Pn) is Benford or eventually zero. Using recent tools that established Benford behavior both for Newton’s method and for finite-dimensional linear maps, via the classical theories of uniform distribution modulo 1 and Perron-Frobenius, this paper …

Reward, Punishment, And Cooperation: A Meta-Analysis, Daniel Balliet, Laetitia B. Mulder, Paul A. M. Van Lange Jul 2011

Reward, Punishment, And Cooperation: A Meta-Analysis, Daniel Balliet, Laetitia B. Mulder, Paul A. M. Van Lange

Research Collection School of Social Sciences

How effective are rewards (for cooperation) and punishment (for noncooperation) as tools to promote cooperation in social dilemmas or situations when immediate self-interest and longer term collective interest conflict? What variables can promote the impact of these incentives? Although such questions have been examined, social and behavioral scientists provide different answers. To date, there is no theoretical and/or quantitative review of rewards and punishments as incentives for cooperation in social dilemmas. Using a novel interdependence-theoretic framework, we propose that rewards and punishments should both promote cooperation, and we identify 2 variables-cost of incentives and source of incentives-that are predicted to …

Crosstalk Between Wnt And Rho Pathways In Ameloblast-Lineage Cells, Kate Shusterman Jul 2011

Crosstalk Between Wnt And Rho Pathways In Ameloblast-Lineage Cells, Kate Shusterman

PCOM Biomedical Studies Student Scholarship

Exposure to high levels of fluoride during tooth development will lead to mineralization defects and a decrease in enamel strength, known as enamel fluorosis. It has been proposed that fluoride may alter the cytoskeleton of ameloblasts, cells that secrete enamel during tooth development. This change is carried out through the Rho pathway, more specifically through RhoA. RhoA is stimulated by Wnt3a, a part of the Wnt pathway involved in regulation of cell proliferation and differentiation. The main component of the Wnt pathway, β-catenin, is expressed in dental epithelium and acts by linking cadherins to the actin cytoskeleton in cell adhesion. …

Revealing Student Thinking About Experimental Design And The Roles Of Control Experiments, Jia Shi, Joy M. Power, Michael W. Klymkowsky Jul 2011

Revealing Student Thinking About Experimental Design And The Roles Of Control Experiments, Jia Shi, Joy M. Power, Michael W. Klymkowsky

International Journal for the Scholarship of Teaching & Learning

Well-designed “controls” distinguish experimental from non-experimental studies. Surprisingly, we found that a high percentage of students had difficulty identifying control experiments even after completing three university-level laboratory courses. To address this issue, we designed and ran a revised cell biology lab course in which students participated in weekly “experimental control exercises.” To measure student understanding of control experiments, we developed a set of assessment questions; these were given to students prior to and following completion of either a standard cell biology lab course or the revised cell biology lab course. Not unexpectedly, the results indicate that the revised course led …

When Responsive Legislation Ignores The Forest For The Trees, Matthew G. Curtis Jul 2011

When Responsive Legislation Ignores The Forest For The Trees, Matthew G. Curtis

Law Student Publications

Large-scale financial disasters have resulted in equally large-scale overhauls of the system responsible for financial industry regulation. Choice over responding parties to these disasters is minimal, and the public inevitably looks to the government for assistance and explanation. The increasingly globalized economy causes any nationwide financial regulation in the U.S. to be felt throughout international markets. U.S. environmental regulation, while not felt immediately abroad, can have drastic impacts on business planning, environmental risk-management, and human rights in the developing world.

Sequential Assembly Of Flagellar Radial Spokes, Dennis R. Diener, Pinfen Yang, Stefan Geimer, Douglas G. Cole, Winfield S. Sale, Joel L. Rosenbaum

Biological Sciences Faculty Research and Publications

The unicellular alga Chlamydomonas can assemble two 10 μm flagella in 1 h from proteins synthesized in the cell body. Targeting and transporting these proteins to the flagella are simplified by preassembly of macromolecular complexes in the cell body. Radial spokes are flagellar complexes that are partially assembled in the cell body before entering the flagella. On the axoneme, radial spokes are “T” shaped structures with a head of five proteins and a stalk of 18 proteins that sediment together at 20S. In the cell body, radial spokes are partially assembled; about half of the radial spoke proteins (RSPs) form …
