Magnetization Reversal Of Fe Films On Ag Submicrometer Pyramidal Islands, Chin-Chung Yu, Yeong-Der Yao, Sy_Hwang Liou Oct 2005

Magnetization Reversal Of Fe Films On Ag Submicrometer Pyramidal Islands, Chin-Chung Yu, Yeong-Der Yao, Sy_Hwang Liou

Sy-Hwang Liou Publications

Ag submicrometer pyramidal islands with a (100) truncated top and four (111) sidewalls were successfully fabricated on Si(100) substrates at a deposition temperature of 500/spl deg/C. The magnetization reversal of 30 nm thick Fe films grown on Ag pyramidal islands was studied by magnetic force microscopy. The magnetization reversal of Fe films was first started at the sidewalls of pyramidal islands. Then, the formation and propagation of wall-like structures were observed under a higher external magnetic field, namely 95 Oe. The magnetic domain images indicated that the Fe films grown on the sidewalls of pyramidal islands and the strength of …

Will Travel For Food: Spatial Discounting In Two New World Monkeys, Jeffrey R. Stevens, Alexandra G. Rosati, Kathryn R. Ross, Marc D. Hauser Oct 2005

Will Travel For Food: Spatial Discounting In Two New World Monkeys, Jeffrey R. Stevens, Alexandra G. Rosati, Kathryn R. Ross, Marc D. Hauser

Department of Psychology: Faculty Publications

Nonhuman animals steeply discount the future, showing a preference for small, immediate over large, delayed rewards [1–5]. Currently unclear is whether discounting functions depend on context. Here, we examine the effects of spatial context on discounting in cotton-top tamarins (Saguinus oedipus) and common marmosets (Callithrix jacchus), species known to differ in temporal discounting [5]. We presented subjects with a choice between small, nearby rewards and large, distant rewards. Tamarins traveled farther for the large reward than marmosets, attending to the ratio of reward differences rather than their absolute values. This species difference contrasts with performance on …

Review Of Amphibians And Reptiles Of Montana By J. Kirwin Werner, Bryce A. Maxell, Paul Hendricks, And Dennis L. Flath, Anthony Russell Oct 2005

Review Of Amphibians And Reptiles Of Montana By J. Kirwin Werner, Bryce A. Maxell, Paul Hendricks, And Dennis L. Flath, Anthony Russell

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This volume documents comprehensively Montana's herpetofauna in a field guide/natural history format. As such, it joins other relatively recently published guides to the herpetofaunas of the northern Great Plains states and provinces that border Montana to provide extensive background information about amphibians and reptiles across this broad region. Assembled by a consortium of authors with a wealth of first-hand experience, the guide is profusely illustrated with color photographs of habitats and animals in the field, almost all of good to excellent quality, though a few are too small or indistinct to illustrate clearly the features being considered. For the most …

Review Of Damselflies Of Alberta: Flying Neon Toothpicks In The Grass By John Acorn, Dennis Lehmkuhl Oct 2005

Review Of Damselflies Of Alberta: Flying Neon Toothpicks In The Grass By John Acorn, Dennis Lehmkuhl

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This book is small enough to fit into a field pack or be rolled up and put in your pocket, but don't be misled by the size: it contains many compelling topics in addition to identification and species accounts. Of special interest is the chapter on the history of damselfly study in Alberta. Settlement of many areas of the Canadian and American Plains occurred about a hundred years ago, and the pattern was similar in many places-avid amateurs or professional biologists began the study of local faunas, and the stories of their personal lives and experiences in those pioneer years …

Review Of Weeds Of The Great Plains By James Stubbendieck, Mitchell 1. Coffin, And L. M. Landholt, Craig Freeman Oct 2005

Review Of Weeds Of The Great Plains By James Stubbendieck, Mitchell 1. Coffin, And L. M. Landholt, Craig Freeman

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Alteration of the Great Plains landscape during the past two centuries has permitted scores of weedy plants to flourish and expand their ranges, often profoundly affecting the ecology and economy of the region. As their numbers have increased, weed identification has become progressively more challenging. More than 600 of the 3,600 species of flowering plants and ferns documented in the Great Plains were not here 200 years ago. This book, updating and replacing Weeds of Nebraska and the Great Plains (1994), intends to enable users to "identify or confirm the identity of the most important weeds in the Great Plains."

Review Of Every Farm A Factory: The Industrial Ideal In American Agriculture By Deborah Fitzgerald, Kimberly Porter Oct 2005

Review Of Every Farm A Factory: The Industrial Ideal In American Agriculture By Deborah Fitzgerald, Kimberly Porter

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

In many ways Deborah Fitzgerald's Every Farm a Factory is a familiar story. Students of early twentieth-century American agriculture will find recognizable contours: mechanization, standardization, economies of scale, depopulation, professionalization, and a developing managerial mind-set. What makes Fitzgerald's work an invigorating contribution to the history of rural America is her framework. The new "opportunities and constraints" confronting farmers and their families in the 1920s, she argues, were not an accidental convergence.

Review Of On The Great Plains: Agriculture And Environment By Geoff Cunfer, Gary Libecap Oct 2005

Review Of On The Great Plains: Agriculture And Environment By Geoff Cunfer, Gary Libecap

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Geoff Cunfer has written an important book about the interaction between humans and nature in the Great Plains between 1870 and the end of the twentieth century. It will be useful to those involved in environmental and ecological science, agriculture and agricultural history, as well as economic history and economic development. One of the largest agricultural landscapes in the U.S., the Great Plains was at one time thought of as "the Great American Desert," and the Northern Great Plains was the last region to be settled on the agricultural frontier. Interpretation of Great Plains history is split between two camps. …

Review Of Perilous Voyages: Czech And English Immigrants To Texas In The 1870s By Lawrence H. Konecny And Clinton Machann, Eva Eckert Oct 2005

Review Of Perilous Voyages: Czech And English Immigrants To Texas In The 1870s By Lawrence H. Konecny And Clinton Machann, Eva Eckert

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Perilous Voyages exemplifies the fact that one can learn much about immigration by focusing on specific journeys. As Konecny and Machann show, this focus enables readers to view immigration as a set of complex decisions of troubled individuals rather than as a movement of masses. The authors have unearthed critical historical materials that shed new light on Texas immigration. The book communicates not only valuable facts but also excitement over discovering previously unpublished materials of narrative interest and historical power: Texas travel adventure in the diary of William Wright (April-May 1879), oral history about the voyage of thirty-six Moravians (1873), …

Language Skills Of Elementary-Aged Children With Emotional And Behavioral Disorders, Gregory Benner Oct 2005

Language Skills Of Elementary-Aged Children With Emotional And Behavioral Disorders, Gregory Benner

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

A cross-sectional design was used to assess the language skills and prevalence of language disorders among 84 randomly selected public school children (K-5) receiving special education services for emotional and behavioral disorders (EBD). The mean receptive language standard score fell in the nonclinical range, whereas the mean total and expressive standard scores fell in the clinical range. The prevalence rates of total, expressive, and receptive disorders among children with EBD were 54%, 55%, and 42%, respectively. Approximately two-thirds of children experienced a language disorder (i.e., total, expressive, and/or receptive). Half of those experiencing a language disorder met clinical criteria in …

Breeding Bird Communities In Riparian Forests Along The Central Platte River, Nebraska, Craig Davis Oct 2005

Breeding Bird Communities In Riparian Forests Along The Central Platte River, Nebraska, Craig Davis

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The Platte River has changed from a nearly treeless prairie river to a heavily forested river. These habitat changes have likely benefited many woodland birds, but have harmed other migratory birds such as cranes. In response to this impact on migratory birds, conservation groups implemented a tree-clearing program to enhance habitat for these species. This practice is not without controversy because of concerns about its effect on woodland birds. The goal of this study was to determine the composition and abundance of breeding birds that use these forests and discuss the potential impacts of tree clearing on woodland birds. Surveys …

Assessing The Economic Development Of Nature Tourism, Nancy Hodur, F. Larry Leistritz, Kara Wolfe Oct 2005

Assessing The Economic Development Of Nature Tourism, Nancy Hodur, F. Larry Leistritz, Kara Wolfe

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Nature tourism is increasingly being considered as an economic development opportunity for rural areas of the Great Plains. As rural communities seek to develop nature tourism, questions regarding the attributes and interests of the nature tourist arise. This study sought to address these questions through a survey of participants at a birding festival held in central North Dakota in June 2004. The festival participants were predominately from outside the local area, and most of these visitors were from out of state. The festival participants were middle-aged and highly educated, and had relatively high income. The visitors spent an average of …

Damage-Induced Modeling Of Asphalt Mixtures Through Computational Micromechanics And Cohesive Zone Fracture, Yong-Rak Kim, D. H. Allen, D. N. Little Oct 2005

Damage-Induced Modeling Of Asphalt Mixtures Through Computational Micromechanics And Cohesive Zone Fracture, Yong-Rak Kim, D. H. Allen, D. N. Little

Department of Engineering Mechanics: Faculty Publications

This paper presents a computational micromechanics modeling approach to predict damage-induced mechanical response of asphalt mixtures. Heterogeneous geometric characteristics and inelastic mechanical behavior were taken into account by introducing finite element modeling techniques and a viscoelastic material model. The modeling also includes interface fracture to represent crack growth and damage evolution. The interface fracture is modeled by using a micromechanical nonlinear viscoelastic cohesive-zone constitutive relation. Fundamental material properties and fracture characteristics were measured from simple laboratory tests and then incorporated into the model to predict rate-dependent viscoelastic damage behavior of the asphalt mixture. Simulation results demonstrate that each model parameter …

Nurse Gordon On Trial: Those Early Days Of The Birth Control Clinic Movement Reconsidered, Rose Holz Oct 2005

Nurse Gordon On Trial: Those Early Days Of The Birth Control Clinic Movement Reconsidered, Rose Holz

Women's and Gender Studies Program: Faculty Publications

It is a story many of us know well. As historian Linda Gordon explained nearly thirty years ago, in the early days of the teens Margaret Sanger was a radical. She talked about sex. She talked about revolution. She criticized doctors. She even opened a clinic in overt defiance of the law. And in this clinic she exercised her skills as a nurse and educated women about birth control. But then, as Gordon’s story also goes, by the 1920s Sanger shifted tactics: she softened her critique and she put a doctor in charge of her new facility, with the message …

Enhanced Pathogenicity Of Candida Albicans Pre-Treated With Subinhibitory Concentrations Of Fluconazole In A Mouse Model Of Disseminated Candidiasis, Dhammika H.M.L.P. Navarathna, Jacob M. Hornby, Natasha Hoerrmann, Anne M. Parkhurst, Gerald E. Duhamel, Kenneth Nickerson Oct 2005

Enhanced Pathogenicity Of Candida Albicans Pre-Treated With Subinhibitory Concentrations Of Fluconazole In A Mouse Model Of Disseminated Candidiasis, Dhammika H.M.L.P. Navarathna, Jacob M. Hornby, Natasha Hoerrmann, Anne M. Parkhurst, Gerald E. Duhamel, Kenneth Nickerson

School of Veterinary and Biomedical Sciences: Faculty Publications

Objectives: To investigate the relative pathogenicity of Candida albicans treated with subinhibitory concentrations of fluconazole in a mouse model of disseminated candidiasis. Previous studies indicate that these cells secrete 10 times more farnesol than do untreated cells. In our usage, subinhibitory means a concentration which causes a prominent decrease in turbidity but still allows some cell growth. Methods: C. albicans A72 cells were grown overnight in 0–5.0 mM fluconazole, washed, and inoculated in mice by tail vein injection. Groups of 15 or 16 mice were injected with 1.3 • 106cells and mortality was recorded for 7 days post-inoculation. …

A Herpes Simplex Virus Type 1 Mutant Expressing A Baculovirus Inhibitor Of Apoptosis Gene In Place Of Latency-Associated Transcript Has A Wild-Type Reactivation Phenotype In The Mouse, Ling Jin, Guey-Chuen Perng, Kevin R. Mott, Nelson Osorio, Julie Naito, David J. Brick, Dale Carpenter, Clinton J. Jones, Steven L. Wechsler Oct 2005

A Herpes Simplex Virus Type 1 Mutant Expressing A Baculovirus Inhibitor Of Apoptosis Gene In Place Of Latency-Associated Transcript Has A Wild-Type Reactivation Phenotype In The Mouse, Ling Jin, Guey-Chuen Perng, Kevin R. Mott, Nelson Osorio, Julie Naito, David J. Brick, Dale Carpenter, Clinton J. Jones, Steven L. Wechsler

School of Veterinary and Biomedical Sciences: Faculty Publications

The latency-associated transcript (LAT) is essential for the wild-type herpes simplex virus type 1 (HSV-1) high-reactivation phenotype since LAT- mutants have a low-reactivation phenotype. We previously reported that LAT can decrease apoptosis and proposed that this activity is involved in LAT’s ability to enhance the HSV-1 reactivation phenotype. The first 20% of the primary 8.3-kb LAT transcript is sufficient for enhancing the reactivation phenotype and for decreasing apoptosis, supporting this proposal. For this study, we constructed an HSV-1 LAT- mutant that expresses the baculovirus antiapoptosis gene product cpIAP under control of the LAT promoter and in place of …

Mountain Plover Population Responses To Black-Tailed Prairie Dogs In Montana, Stephen J. Dinsmore, Gary C. White, Fritz L. Knopf Oct 2005

Mountain Plover Population Responses To Black-Tailed Prairie Dogs In Montana, Stephen J. Dinsmore, Gary C. White, Fritz L. Knopf

United States Geological Survey: Staff Publications

We studied a local population of mountain plovers (Charadrius montanus) in southern Phillips County, Montana, USA, from 1995 to 2000 to estimate annual rates of recruitment rate (f) and population change (λ). We used Pradel models, and we modeled λ as a constant across years, as a linear time trend, as year-specific, and with an additive effect of area occupied by prairie dogs (Cynomys ludovicianus). We modeled recruitment rate (f) as a function of area occupied by prairie dogs with the remaining model structure identical to the best model used to estimate λ. Our results indicated …

The Finding Of Echinostoma (Trematoda: Digenea) And Hookworm Eggs In Coprolites Collected From A Brazilian Mummified Body Dated 600–1,200 Years Before Present, L. Sianto, Karl J. Reinhard, M. Chame, S. Chaves, S. Mendonça, M. L. C. Gonçalves, A. Fernandes, L. F. Ferreira, A. Araújo

School of Natural Resources: Faculty Publications

The identification of parasites from ancient cultures expands our list of parasites infective to extant humans. A partially mummified human body from the archeological site of Lapa do Boquete, Minas Gerais State, Brazil, was recently discovered. It was interred between 600 and 1,200 yr ago. Dietary analysis showed that the mummified body was from a society that had a mixed subsistence of agriculture and gathering of wild foods. Coprolites from the body contained numerous helminth eggs. The eggs were identified as those of Echinostoma sp. and hookworm. Hookworm infection in pre-Columbian populations is already established, but this is the first …

Nurturing The Spirit At Work: Impact On Work Unit Performance, Dennis Duchon, Donde Ashmos Plowman Oct 2005

Nurturing The Spirit At Work: Impact On Work Unit Performance, Dennis Duchon, Donde Ashmos Plowman

Department of Management: Faculty Publications

Workplace spirituality is defined as a workplace that recognizes that employees have an inner life that nourishes and is nourished by meaningful work that takes place in the context of community. This definition, based on three fundamental spiritual needs, has implications for how leaders can enhance work unit performance by nurturing the spirit at work. In an exploratory study of six work units in a large hospital system we used an instrument that measures workplace spirituality. The results led to propositions concerning the effect of work unit spirituality on work unit performance and the relationship between work unit spirituality and …

Good Faith Business Judgment: A Theory Of Rhetoric In Corporate Law Jurisprudence, Sean J. Griffith Oct 2005

Good Faith Business Judgment: A Theory Of Rhetoric In Corporate Law Jurisprudence, Sean J. Griffith

Duke Law Journal

This Article develops a theory of rhetoric in corporate law jurisprudence. It begins by examining a recent innovation in Delaware case law: the emerging principle of "good faith." Good faith is an old notion in law generally, but it offers to bring significant change to corporate law, including realignment of the business judgment rule and a shift in the traditional balance between the authority of boards and the accountability of boards to courts. This Article argues, however, that good faith functions as a rhetorical device rather than a substantive standard. That is, it operates as a speech act, a performance, …

Coarse-Grained Free-Energy-Functional Treatment Of Quasistatic Multiscale Processes In Heterogeneous Materials, H. Zhou, Ruqiang Feng, Dennis J. Diestler, Xiao Cheng Zeng Oct 2005

Coarse-Grained Free-Energy-Functional Treatment Of Quasistatic Multiscale Processes In Heterogeneous Materials, H. Zhou, Ruqiang Feng, Dennis J. Diestler, Xiao Cheng Zeng

Xiao Cheng Zeng Publications

A new treatment of quasistatic (reversible) multiscale processes in heterogeneous materials at nonzero temperature is presented. The system is coarse grained by means of a finite-element mesh. The coarse-grained free-energy functional (of the positions of the nodes of the mesh) appropriate to the thermodynamic-state variables controlled in the relevant process is minimized. Tests of the new procedure on a Lennard-Jonesium crystal yield thermomechanical properties in good agreement with the “exact” atomistic results.

Performance Evaluation Of Distributed Security Protocols Using Discrete Event Simulation, Meiyuan Zhao Oct 2005

Performance Evaluation Of Distributed Security Protocols Using Discrete Event Simulation, Meiyuan Zhao

Dartmouth College Ph.D Dissertations

The Border Gateway Protocol (BGP) that manages inter-domain routing on the Internet lacks security. Protective measures using public key cryptography introduce complexities and costs. To support authentication and other security functionality in large networks, we need public key infrastructures (PKIs). Protocols that distribute and validate certificates introduce additional complexities and costs. The certification path building algorithm that helps users establish trust on certificates in the distributed network environment is particularly complicated. Neither routing security nor PKI come for free. Prior to this work, the research study on performance issues of these large-scale distributed security systems was minimal. In this thesis, …

The Cytolethal Distending Toxin B Sub-Unit Of Helicobacter Hepaticus Is A Ca2+- And Mg2+-Dependent Neutral Nuclease, Rohana P. Dassanayake, Mark A. Griep, Gerald Duhamel Oct 2005

The Cytolethal Distending Toxin B Sub-Unit Of Helicobacter Hepaticus Is A Ca2+- And Mg2+-Dependent Neutral Nuclease, Rohana P. Dassanayake, Mark A. Griep, Gerald Duhamel

Mark A. Griep Publications

The cytolethal distending toxin B (CdtB) of the mouse pathogen Helicobacter hepaticus has cation binding and DNA catalysis residues in common with members of the mammalian deoxyribonuclease I (DNase I) family. The purpose of the present study was to characterize CdtB nuclease. To establish optimal digestion conditions and to evaluate co-factor requirements, a novel and sensitive fl uorometric assay that quantitatively determines double stranded DNA digestion was developed. Although the Ca2+- and Mg2+-dependence and neutral properties of CdtB were similar to DNase I, hydrolysis of DNA by CdtB was approximately 100-fold less active than DNase I …

Upfc Control Employing Gradient Descent Search, William M. Siever, Radha P. Kalyani, Mariesa Crow, Daniel R. Tauritz Oct 2005

Upfc Control Employing Gradient Descent Search, William M. Siever, Radha P. Kalyani, Mariesa Crow, Daniel R. Tauritz

Electrical and Computer Engineering Faculty Research & Creative Works

Increasing demand coupled with limitations on new construction indicate that existing power transmission must be better controlled in order to continue reliable operation. Recent advances in FACTS devices provide a mechanism to better control power flow on the transmission network. One particular device, the unified power flow controller (UPFC), holds the most promise for maintaining operation even when the system has suffered partial failure (either naturally occurring, due to human error, or a malicious attack). In addition to the capital cost, the primary obstacles to widespread UPFC use are the combined problems of selecting the most cost effective locations for …
