Ultrashort Laser Pulse Heating Of Nanoparticles: Comparison Of Theoretical Approaches, Thomas George, R. Letfullin

Chemistry & Biochemistry Faculty Works

The interaction between nanoparticles and ultrashort laser pulses holds great interest in laser nanomedicine, introducing such possibilities as selective cell targeting to create highly localized cell damage. Two models are studied to describe the laser pulse interaction with nanoparticles in the femtosecond, picosecond, and nanosecond regimes. The first is a two-temperature model using two coupled diffusion equations: one describing the heat conduction of electrons, and the other that of the lattice. The second model is a one-temperature model utilizing a heat diffusion equation for the phonon subsystem and applying a uniform heating approximation throughout the particle volume. A comparison of …

The Dynamic Evolutionary History Of The Bananaquit (Coereba Flaveola) In The Caribbean Revealed By A Multigene Analysis, Eva Bellemain, Eldredge Bermingham, Robert Ricklefs

Biology Department Faculty Works

BackgroundThe bananaquit (Coereba flaveola) is a small nectivorous and frugivorous emberizine bird (order Passeriformes) that is an abundant resident throughout the Caribbean region. We used multi-gene analyses to investigate the evolutionary history of this species throughout its distribution in the West Indies and in South and Middle America. We sequenced six mitochondrial genes (3744 base pairs) and three nuclear genes (2049 base pairs) for forty-four bananaquits and three outgroup species. We infer the ancestral area of the present-day bananaquit populations, report on the species' phylogenetic, biogeographic and evolutionary history, and propose scenarios for its diversification and range expansion.ResultsPhylogenetic concordance between …

The Plant Ontology Consortium (POC, http://www.plantontology.org ) is a collaborative effort among model plant genome databases and plant researchers that aims to create, maintain and facilitate the use of a controlled vocabulary (ontology) for plants. The ontology allows users to ascribe attributes of plant structure (anatomy and morphology) and developmental stages to data types, such as genes and phenotypes, to provide a semantic framework to make meaningful cross-species and database comparisons. The POC builds upon groundbreaking work by the Gene Ontology Consortium (GOC) by adopting and extending the GOC's principles, existing software and database structure. Over the past year, POC …

Puf1p Acts In Combination With Other Yeast Puf Proteins To Control Mrna Stability, Wendy Olivas, Randi Ulbricht

Biology Department Faculty Works

The eukaryotic Puf proteins bind 3′ untranslated region (UTR) sequence elements to regulate the stability and translation of their target transcripts, and such regulatory events are critical for cell growth and development. Several global genome analyses have identified hundreds of potential mRNA targets of the Saccharomyces cerevisiae Puf proteins; however, only three mRNA targets for these proteins have been characterized thus far. After direct testing of nearly 40 candidate mRNAs, we established two of these as true mRNA targets of Puf-mediated decay in yeast, HXK1 and TIF1. In a novel finding, multiple Puf proteins, including Puf1p, regulate both of these …

Electroconvulsive Therapy : A Brief Overview, Adam A. Sauceda

Graduate Research Papers

Electroconvulsive therapy (ECT) has been increasing in popularity for treating various types of mental health disorders. Although a notably controversial medical procedure, ECT continues to be an option when intense therapy and psychopharmacology fails. This research project will review the recent literature on ECT and provide useful information specific to mental health professionals. A definition, administration procedures, effectiveness, side effects, and specific disorders that have been targeted and most and least receptive for ECT treatment will be the focus of attention

Comparison Of Plant Growth-Promotion With Pseudomonas Aeruginosa And Bacillus Subtilis In Three Vegetables, A. O. Adesemoye, M. Obini, E. O. Ugoji

Department of Plant Pathology: Faculty Publications

Our objective was to compare some plant growth-promoting rhizobacteria (PGPR) properties of Bacillus subtilis and Pseudomonas aeruginosa as representatives of their two genera. Solanum lycopersicum L. (tomato), Abelmoschus esculentus (okra), and Amaranthus sp. (African spinach) were inoculated with the bacterial cultures. At 60 days after planting, dry biomass for plants treated with B. subtilis and P. aeruginosa increased 31% for tomato, 36% and 29% for okra, and 83% and 40% for African spinach respectively over the non-bacterized control. Considering all the parameters tested, there were similarities but no significant difference at P < 0.05 between the overall performances of the two organisms.

Dams, Duties, And Discretion: Bureau Of Reclamation Water Project Operations And The Endangered Species Act, Reed D. Benson

Faculty Scholarship

Nearly thirty years ago, the U.S. Supreme Court decided whether the survival of a relatively small number of three-inch fish among all the countless millions of species extant would require the permanent halting of a virtually completed dam for which Congress has expended more than $100 million.' Stunningly, the fish won, because the language, history, and structure of the Endangered Species Act showed 'beyond doubt that Congress intended endangered species to be afforded the highest of priorities.' The Court acknowledged that this view of the statute would carry substantial economic costs, but was persuaded that '[t]he plain intent of Congress …

Voluntary Exercise Inhibits Intestinal Tumorigenesis In Apc(Min/+) Mice And Azoxymethane/Dextran Sulfate Sodium-Treated Mice., Jihyeung Ju, Bonnie Nolan, Michelle Cheh, Mousumi Bose, Yong Lin, George C. Wagner, Chung S. Yang

Department of Nutrition and Food Studies Scholarship and Creative Works

BACKGROUND: Epidemiological studies suggest that physical activity reduces the risk of colon cancer in humans. Results from animal studies, however, are inconclusive. The present study investigated the effects of voluntary exercise on intestinal tumor formation in two different animal models, Apc(Min/+) mice and azoxymethane (AOM)/dextran sulfate sodium (DSS)-treated mice. METHODS: In Experiments 1 and 2, five-week old female Apc(Min/+) mice were either housed in regular cages or cages equipped with a running wheel for 6 weeks (for mice maintained on the AIN93G diet; Experiment 1) or 9 weeks (for mice on a high-fat diet; Experiment 2). In Experiment 3, male …

An Examination On The Impact Of School Grade Configuration On Eighth Grade Student Academic Achievement In Reading, Writing, And Math, Joyce Lutrey

Master's Theses and Doctoral Dissertations

The purpose of this research effort was to examine the impact of grade configuration on eighth grade student achievement in Math, Reading, and Writing. The quantitative research design used publicly available data and studied the 2000 through 2007 Arizona standards-based, eighth grade student test results across six grade configurations for all Arizona eighth grade students. Additional variables included student gender, ethnicity, socio-economic status, and charter versus public schools.

Chi-square testing showed there were student achievement differences in Math, Reading, and Writing across grade configuration, ethnicity, socio-economic status, and between charters and public schools. These differences were likely due to the …

An Examination Of The Relationship Of Six Risk Factors Associated With Dropping Out Of High School For Students With Disabilities In South Central Michigan, Dawn Gallup

Master's Theses and Doctoral Dissertations

The purpose of this non-experimental, quantitative, retrospective (ex post facto), research in south central Michigan was to determine the relationship of six risk factors associated with dropping out of high school to students with disabilities (SWDs). The six risk factors were (a) grade retention (never held back or held back one or more times), (b) age compared to peers (same age as peers or one year or older than peers), (c) limited English proficiency (English speaking or English as a second language), (d) category of disability (learning disabled/emotionally impaired or cognitively impaired/other), (e) mobility (the number of school districts or …

The Space Between Aristotle And The Bush Administration: Considering The Impact Of "Goodwill" On International Relations, Anke Thorey Wolbert

Master's Theses and Doctoral Dissertations

Focusing on the Bush Administration’s post-September 11 rhetoric, this thesis investigates the impact this rhetoric had on the Administration’s perceived credibility by the international community with specific focus on Germany’s, France’s, and Great Britain’s reactions. Of particular interest is the importance of eunoia (goodwill) as an aspect of the speaker’s ethos. Considering that goodwill has been viewed as the lost dimension of Aristotle’s ethos (credibility) this analysis provides the basis to argue that goodwill should be treated as a major component of ethos.

A textual analysis of rhetorical acts as well as media reactions sheds light on the role goodwill …

Approaches To Personality Disorder Diagnosis: Comparing The Cognitive Affective Processing And The Five Factor Models Of Personality, Cortney C. Rhadigan

Master's Theses and Doctoral Dissertations

The Cognitive-Affective Processing Model (CAPS) suggests that personality is best understood as a collection of cross-situationally consistent traits that are expressed based upon features of the situation. This differs from the Five Factor Model (FFM) of personality, in which personality is believed to be composed of five broad trait domains that are observed consistently across multiple situations. This study compares the diagnostic accuracy of 202 licensed members of the Michigan Psychological Association who assessed personality pathology using short vignettes written to represent situationally-specific expression of traits (CAPS) compared to vignettes written with FFM trait description and DSM-IV TR description. The …

The Development Of Caching Behavior, Cache Site And Cache Item Defense Tactics, And Cache Site And Cache Item Sharing In Orphaned Fledgling Blue Jays (Cyanocitta Cristata) At A Songbird Rehabilitation Center, Deanna Martinez

Master's Theses and Doctoral Dissertations

One of the primary goals of songbird rehabilitators is to promote controllable factors that increase survivorship in orphaned songbirds upon to release. As caching serves an important function in corvid life, this study sought to determine if this behavior would develop with or without outside input. Eight orphaned blue jays (consisting of both hatchlings and nestlings) were brought into the care of the Bird Center of Washtenaw County, Inc. in Ann Arbor, Michigan. Birds were videotaped and observed for the development of caching behavior, cache item and cache site sharing, and cache defense tactics. Caching behavior and cache defense tactics …

An Improved String Composition Method For Sequence Comparison, Guoqing Lu, Shunpu Zhang, Xiang Fang

Department of Statistics: Faculty Publications

Background: Historically, two categories of computational algorithms (alignment-based and alignment-free) have been applied to sequence comparison–one of the most fundamental issues in bioinformatics. Multiple sequence alignment, although dominantly used by biologists, possesses both fundamental as well as computational limitations. Consequently, alignment-free methods have been explored as important alternatives in estimating sequence similarity. Of the alignment-free methods, the string composition vector (CV) methods, which use the frequencies of nucleotide or amino acid strings to represent sequence information, show promising results in genome sequence comparison of prokaryotes. The existing CV-based methods, however, suffer certain statistical problems, thereby underestimating the amount of evolutionary …

Amphetamine Selectively Enhances Avoidance Responding To A Less Salient Stimulus In Rats, Ming Li, Wei He, Rebecca Munro

Department of Psychology: Faculty Publications

This preclinical study examined the psychological processes affected by amphetamine that contribute to human psychosis. Using a novel avoidance conditioning paradigm involving two conditioned stimuli (CS) with varied salience, we found that acute amphetamine (1.5 mg/ kg, i.p.) selectively enhanced avoidance responding to a less salient stimulus, but not to a salient one. These findings suggest that elevated dopaminergic activity selectively enhances the attributions of motivational salience to a less salient stimulus, a process that may bear relevance to the development of human delusional thoughts.

Breakfast At The Cockpit Café And Other Innovations In Protected Area Outreach, Christine Baumann Feurt, Ward Feurt

United States Fish and Wildlife Service: Publications

Fundamental changes in protected area outreach and education strategies are dissolving old boundaries and fostering innovative approaches to civic engagement. The practice of community-based ecosystem management as presented by Meffe et al. (2002) provides an organizing framework blending ecological, institutional and sociocultural perspectives. This framework flows from a definition of ecosystem management that considers sustaining ecosystem structure and processes across spatial and temporal scales in tandem with societal priorities. The decision-making authority in this system, envisioned as collaborative and participatory, can present challenges for traditionally trained protected area managers. This definition views ecosystem management as: . . . an approach …

American Woodcock Population Status, 2008, Thomas R. Cooper, Keri Parker, Rebecca D. Rau

United States Fish and Wildlife Service: Publications

Singing-ground Survey data for 2008 indicated that the numbers of displaying American woodcock (Scolopax minor) in the Central Region declined 9.2 % from 2007; however, the Eastern Region was unchanged. There was no significant 10-year trend for woodcock heard in the Eastern Region during 1998-2008, while there was a significant decline in the Central Region. This represents the fifth consecutive year that the 10-year trend estimate did not indicate a significant decline in the Eastern Region, while it marks the first time since 2003 that the Central Region has had a declining 10-year trend. There were long-term (1968-08) …
