An Environment For Mobile Context-Based Hypermedia Retrieval, James Carswell

Conference papers

This paper proposes a novel solution to querying hyperlinked multimedia cultural heritage datasets based on the user's context. Context in this sense is defined as the user's location in virtual space and the particular mobile device being modeled together with user preferences or profile. The purpose is to automatically push relevant data from the database server to the client based on this comprehensive definition of the user's context. Consideration in regard to which mobile device is currently being modeled is a primary filter for determining what data will be sent and in what format. For example, image data will not …

Teacher Persistence: A Crucial Disposition, With Implications For Teacher Education, Karl F. Wheatley

Essays in Education

Teacher persistence helps foster effective teaching. Specifically, teacher persistence may promote high expectations for students, the development of teaching skills, teachers’ reflectiveness, responsiveness to diversity, teaching efficacy, effective responses to setbacks, and successful use of reformed teaching methods. Common evaluation practices in teacher education may undermine teacher persistence. Teacher educators might support the development of teacher persistence by emphasizing the knowledge that makes persistence a rational response to setbacks, by teaching self-regulation skills that support persistence, and by using evaluation practices that require greater effort and persistence of students. The importance of fostering thoughtful teacher persistence is discussed, along with …

Charter Schools And Equal Access: Implications For Magnet And Other Choice Schools, Carrie Ausbrooks

Essays in Education

American public schools have been entrusted with the responsibility of inculcating citizens with democratic values. However, schools have come under attack for a variety of reasons. School choice provides parents with opportunities to select from options, both within and outside the public system of schooling, which will provide their children with the type of education they desire. Among these school choice options are charter and magnet schools. This article begins with a discussion of the basic similarities between magnet and charter schools, followed by a discussion of a legal research study which examined the extent to which U.S. charter school …

Coupling Of Termination, 3′ Processing, And Mrna Export, C. M. Hammell, Stefan Gross, Daniel Zenklusen, Catherine V. Heath, Francoise Stutz, Claire Moore, C. N. Cole

Dartmouth Scholarship

In a screen to identify genes required for mRNA export in Saccharomyces cerevisiae, we isolated an allele of poly(A) polymerase (PAP1) and novel alleles encoding several other 3′ processing factors. Many newly isolated and some previously described mutants (rna14-48, rna14-49, rna14-64, rna15-58, and pcf11-1 strains) are defective in polymerase II (Pol II) termination but, interestingly, retain the ability to polyadenylate these improperly processed transcripts at the nonpermissive temperature. Deletion of the cis-acting sequences required to couple 3′ processing and termination also …

Seeking Salvation For Accountability, Melvin J. Dubnick

Faculty Publications

This is a paper in defense of a concept that is threatened by its popularity and undermined by those who use it most. It is a call for a reexamination and reaffirmation of “accountability” from the perspective of its central role in modern governance. It is a plea for saving the concept of accountability from the abuses it suffers in the hands of friends and advocates. It is an effort at salvation for a concept that has lost its meaningful “soul” in a world filled with rhetoricians, reformers, and functionalists – all well intentioned, but each contributing to accountability’s fall …

Seedlayer And Preheating Effects On Crystallography And Recording Performance Of Cocrptb Perpendicular Media, Min Zheng, Geon Choe, Kenneth E. Johnson, Lan Gao, Sy_Hwang Liou

Department of Physics and Astronomy: Faculty Publications

The effects of seedlayer (SL) and preheating on the crystallographic, magnetic, and recording properties of CoCr₁₈Pt₁₆B₄ granular perpendicular magnetic media have been investigated. For the media with Ru as underlayer, although higher preheating improves both coercivity and squareness, the media is much noisier. With introducing Ta SL, Ru (0002)/Co (0002) crystallography is greatly enhanced. High coercivity, unity squareness, and negative nucleation field are achieved even at low preheating without degrading signal-to-noise ratio. In addition, the media is magnetically stable for a wide range of recording density.

Closed-Form Solution For The Size Of Plastic Zone In An Edge-Cracked Strip, Xiang-Fa Wu, Yuris A. Dzenis

Department of Engineering Mechanics: Faculty Publications

This paper is concerned with the problem of plastic zone at the tip of an edge crack in an isotropic elastoplastic strip under anti-plane deformations. By means of complex potential and Dugdale model, the stress intensity factor and the size of plastic zone are obtained in closed-form. Furthermore, the analytic solutions for an edge crack at the free boundary of a half-space and a semi-infinite crack heading towards a free surface are determined as the limiting cases of the strip geometries.

Mycobacterium Smegmatis L-Alanine Dehydrogenase (Ald) Is Required For Proficient Utilization Of Alanine As A Sole Nitrogen Source And Sustained Anaerobic Growth, Zhengyu Feng, Nancy E. Caceres, Gautam Sarath, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

NAD(H)-dependent L-alanine dehydrogenase (EC 1.4.1.1) (Ald) catalyzes the oxidative deamination of L-alanine and the reductive amination of pyruvate. To assess the physiological role of Ald in Mycobacterium smegmatis, we cloned the ald gene, identified its promoter, determined the protein expression levels, and analyzed the combined effects of nutrient supplementation, oxygen availability, and growth stage on enzyme activity. High Ald activities were observed in cells grown in the presence of L- or D-alanine regardless of the oxygen availability and growth stage. In exponentially growing cells under aerobic conditions, supplementation with alanine resulted in a 25- to 50-fold increase in the …

Closed-Form Solution For A Mode-Iii Interfacial Edge Crack Between Two Bonded Dissimilar Elastic Strips, Xiangfa Wu, Yuris A. Dzenis

Department of Engineering Mechanics: Faculty Publications

A closed-form solution is obtained for the problem of a mode-III interfacial edge crack between two bonded semi-infinite dissimilar elastic strips. A general out-of-plane displacement potential for the crack interacting with a screw dislocation or a line force is constructed using conformal mapping technique and existing dislocation solutions. Based on this displacement potential, the stress intensity factor (SIF, K_III) and the energy release rate (ERR, G_III) for the interfacial edge crack are obtained explicitly. It is shown that, in the limiting special cases, the obtained results coincide with the results available in the literature. The present …

Tuberculosis Of The Knee, Umayya M. Musharrafieh, George F. Araj, Ghazi S. Zaatari, Ramzi S. Musharrafieh

Saudi Medical Journal

Tuberculosis is a worldwide problem that has persisted in developing countries and is re-emerging in developed ones. Infectious complications with Mycobacterium tuberculosis have also been reported with increasing frequency. Among these, skeletal and intra-articular infections continue to affect patients and pose a difficult diagnostic problem to physicians and orthopedic surgeons. This is so, as the non-specific clinical presentation which, overlaps with several infectious and non-infectious diseases, and the latency period of this bacteria that can persist up to several years after the initial infection, contribute to diagnosis and management delay. Thus due to the paucity of the disease, physicians should …

Comparative Literature In An Age Of "Globalization", Lois Parkinson Zamora

CLCWeb: Comparative Literature and Culture

Lois Parkinson Zamora, in her paper "Comparative Literature in an Age of 'Globalization'," presents a definition of globalization and considers how its cultural and spatial displacements have, and might, change traditional disciplinary practices of comparative literature. Zamora discusses how contemporary Latin American writers dramatize and evaluate the forces of globalization in their fiction and she exemplifies her observations with texts by Carpentier, Borges, Paz, Fuentes, Puig, García Márquez, and Vargas Llosa. Further, the author proposes that the cultural specificity of fictions by contemporary Latin American writers may serve as an antidote to current processes of cultural homogenization.

Remediation Of Chromium Contaminated Soils With Colloidal Silica, Netnapid Yossapol

Dissertations

The low-viscosity stabilizer, colloidal silica, is extensively used as a grouting material in the construction of grout curtains. It has low viscosity and is non-toxic, which is suitable for injection to stabilize fine-grained soils. It is also applied as a stabilizer in the in-situ treatment of hazardous waste. Once the colloidal silica solution is injected into contaminated soil, it moves through the pores inside the soil matrix, initiating the stabilization process. The viscosity of the colloidal silica mixture increases while it moves until solidifications. This process is called gelation and results in the creation of a gel barrier around contaminated …

Catalytic Reduction Of Nitric Oxide By Solid Carbonaceous Material Under Lean Condition, Shan Xiao

Dissertations

The reactions of O₂, NO_x and soot from Diesel exhaust over Cu containing catalysts can significantly reduce soot and NO_x emissions while producing N₂ and CO₂. The author has evaluated the performance of Cu ion exchanged ZSM-5 and Cu adsorbed on Granulated Activated Carbon (Cu-GAC) using GAC as a surrogate for soot in a packed bed reactor. CO, formed primarily by the oxidation of GAC with O₂, appears to be a stable intermediate in the reduction of NO. With experimental parameters chosen to simulate Diesel exhaust conditions, Cu-GAC is much more …

Atomic Force Microscopy Used To Determine The Young's Modulus Of Vascular Smooth Muscle Cells, Samuel C. Lieber

Theses

The Young's modulus of cultured mouse and rat vascular smooth muscle cells (VSMC) was measured with an atomic force microscope (AFM). The AFM can image the three-dimensional structure of biological cells in a physiological environment enabling real-time biochemical and physiological processes to be monitored at a resolution similar to that obtained for the electron microscope (EM). Cellular mechanical properties were determined by indenting the cell's body, and analyzing the indentation data with classical infinitesimal strain theory. This calculation was accomplished by modeling the AFM probe as a cone. as well as a blunted cone. The blunted cone geometry fits the …
