Ground Control Support Consideration For Pre-Driven Longwall Recovery Rooms., Stephen Cesare Tadolini Jan 2003

Ground Control Support Consideration For Pre-Driven Longwall Recovery Rooms., Stephen Cesare Tadolini

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pre-driven longwall recovery rooms can be used to safely recover longwall equipment from the current coal panel. The entry is developed and supported ahead of time so that the required combinations of standing and internal supports can be installed before the longwall face approaches. The combination of the internal bolting system and the standing concrete supports are critical for the successful and safe extraction of the longwall equipment. A combined support system that is too soft or too stiff can result in excessive recovery room closures or brittle failures of the concrete crib systems. Three-Dimensional finite element models, combined with …

Second Natures: Media, Masculinity And The Natural World In Twentieth-Century American Literature And Film., Jeanne E. Hamming Jan 2003

Second Natures: Media, Masculinity And The Natural World In Twentieth-Century American Literature And Film., Jeanne E. Hamming

Graduate Theses, Dissertations, and Problem Reports (ETD)

This multidisciplinary dissertation examines the cultural anxieties associated with masculine identity in relation to both technology and nature in key literary texts and contemporary films of the twentieth-century: Ray Bradbury's “The Veldt” and The Martian Chronicles, Philip K. Dick's Do Androids Dream of Electric Sheep?, James Dickey's Deliverance , Don DeLillo's White Noise, Fight Club, American Psycho, Brazil, 12 Monkeys, and Dark City. Exploring the theoretical intersections of technoculture, ecocriticism, and gender studies, this dissertation analyzes the relationship between masculine identity and nature, as it is mediated by American technoculture. This relationship is marked by a discernible cultural malaise—a sense …

Epr And Endor Studies Of Point Defects In Lithium Triborate And Beta-Barium Borate., Wei Hong Jan 2003

Epr And Endor Studies Of Point Defects In Lithium Triborate And Beta-Barium Borate., Wei Hong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electron paramagnetic resonance (EPR) and electron-nuclear double resonance (EN-DOR) have been used to identify and characterize point defects in nonlinear optical crystals of lithium triborate (LiB3O5) and beta barium borate (β-BaB2O4). Two similar hole centers, one (Hole Center A) stable below approximately 130 K and the other one (Hole Center B) stable below approximately 170 K, were observed in LiB3O 5. For both centers, there is a major hyperfine interaction with only one 11B nucleus. The g matrix and the 11B hyperfine and nuclear quadrupole matrices have been determined for each hole center. I suggest Hole Center A is a …

Framing The View: The *Western Landscape And Nineteenth-Century Narratives Of Expansion., Thomas P. Kinnahan Jan 2003

Framing The View: The *Western Landscape And Nineteenth-Century Narratives Of Expansion., Thomas P. Kinnahan

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study traces the flowering of Western scientific exploration during the fifteen years following the Civil War. During these years, the empirical modes of perception and representation associated with Western exploration gained growing cultural authority and increasingly came to frame discussions of Western policy. At the same time, the systematic exploration of the West revealed the region in new and sometimes startling ways, in some cases prompting far-reaching revisions in the nation's self-perception. The stakes of these revisions became especially acute in the 1870's as the nation's frontier line flowed toward the alien landscapes of the arid West, prompting both …

The Impact Of Student Discourse And Journal Writing On The Mathematics Achievement Of Fifth-Grade Students., Lesley A. Klishis Jan 2003

The Impact Of Student Discourse And Journal Writing On The Mathematics Achievement Of Fifth-Grade Students., Lesley A. Klishis

Graduate Theses, Dissertations, and Problem Reports (ETD)

In its Curriculum and Evaluation Standards for School Mathematics, the National Council of Teachers of Mathematics called for a new vision of what is means to be mathematically literate (NCTM, 2000). A major goal of this reform movement has been to provide students with opportunities to develop "mathematical habits of the mind to not only know the signs, symbols, and terms of mathematics, but to read, write, and discuss mathematics. This study investigated the relationship between instructional strategies and student understanding in mathematics. Specifically, the study explored whether student discourse is a desirable prerequisite of journal writing, and whether the …

Technological Evaluation Of Mineral Sequestration Of Carbon Dioxide By Carbonation., Xinchao Wei Jan 2003

Technological Evaluation Of Mineral Sequestration Of Carbon Dioxide By Carbonation., Xinchao Wei

Graduate Theses, Dissertations, and Problem Reports (ETD)

Increase in CO2 emissions has led to development of various mitigation technologies for avoiding CO2 building up in the atmosphere. One of CO2 sequestration technologies is mineral sequestration, a way of permanent storage of CO2 in solid minerals. This technology attracts the attention of many investigators to study and develop various carbonation approaches. The chemistry and thermodynamic studies show that mineral carbonation reactions with silicate minerals are spontaneous and exothermic. A variety of measures are needed to enhance the carbonation kinetics. The main minerals used for mineral sequestration are serpentine and olivine, which exist in vast quantities worldwide. Implementation of …

Affective Factors In Second Language Acquisition: A Critical Review Of The Literature., Laura M. Yokochi Jan 2003

Affective Factors In Second Language Acquisition: A Critical Review Of The Literature., Laura M. Yokochi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Learning a second language is fundamentally different from child language development as well as from the study of other academic disciplines. One reason may be that the study of a second language involves the emotions and the identity in a way other subjects do not. Schumann (1998) argues that emotion filters all learning and cognition. If this is true then the study of affective factors in second language learning is important. What research has been done in this area and what does it show? The purpose of this paper is to conduct a critical review of empirical studies on the …

A Study Of Classic Films And Their Portrayal Of The Mentally Ill., Allison Marie Plants Jan 2003

A Study Of Classic Films And Their Portrayal Of The Mentally Ill., Allison Marie Plants

Graduate Theses, Dissertations, and Problem Reports (ETD)

The media have an enormous influence on the way the public views mental illness. Their frequent and often flawed portrayals of the mentally ill cause negative feelings to develop. Media framing plays a powerful role in the portrayal of the mentally ill. The way the media portray the mentally ill directly affects how they are viewed in real life.

Martel's Routes In Mammoth Cave, Kentucky, 1912, Trevor R. Shaw Jan 2003

Martel's Routes In Mammoth Cave, Kentucky, 1912, Trevor R. Shaw

International Journal of Speleology

Martel’s own copy of the Hovey 1912 guidebook to Mammoth Cave has his routes marked faintly in pencil on the printed cave plans. These plans are reproduced here, with his routes indicated on them. He generally followed the four standard tourist routes which now included Kaemper’s 1908 discoveries to Violet City, but instead of visiting the Maelstrom he went to Hovey’s Cathedral and Gerta’s Grotto.

Human Impact On Karst: The Example Of Lusaka (Zambia), Jo De Waele, Roberto Follesa Jan 2003

Human Impact On Karst: The Example Of Lusaka (Zambia), Jo De Waele, Roberto Follesa

International Journal of Speleology

Lusaka, the capital of Zambia with over 2,000,000 inhabitants, is built on an extensive plateau composed mainly of schists and dolomitic marbles, constituting a very important aquifer that provides the city with almost half of its drinking water needs. Recent demographic growth, leading to uncontrolled urban expansion, and mismanagement of the water resource and of urban waste has lead, in the past 20 years, to an overexploitation of the aquifer and to a generalised water quality depletion, putting in serious danger the future social and economical development of the capital. This third world city has, for these reasons, become a …

A search for narrow-width resonances that decay into electron+jet or neutrino+jet has been performed with the ZEUS detector at the DESY ep collider HERA operating at center-of-mass energies of 300 and 318 GeV. An integrated e+p luminosity of 114.8 pb-1 and e-p luminosity of 16.7 pb-1 were used. No evidence for any resonance was found. Limits were derived on the Yukawa coupling λ as a function of the mass of a hypothetical resonance that has arbitrary decay branching ratios into eq or vq. These limits also apply to squarks predicted by R-parity-violating supersymmetry. Limits for the production of leptoquarks described …
