A History of the Development of the University of Tennessee, Martin Branch

The University of Tennessee, Martin Branch, has developed through four distinct states in response to educational needs in upper West Tennessee. The State failed to support education adequately and other groups organized schools in response to this failure to meet the need in education. The local Baptist Association organized and supported Hall-Moody Institute in response to this need, and the school continued to operate until 1927, when the college was consolidated with Union University at Jackson, Tennessee. At the time that the Junior College was established at Martin, local citizen support was strong in the General Assembly. In fact, the support was strong enough that Dr. Andrew D. Holt, in his study conducted at Columbia University, credited the combined efforts of three groups--the Martin group, the Clarksville group, and the educational forces--with the success of three aspects of educational legislation. A junior college was established at Martin; a college was established at Clarksville; and the passage of favorable school legislation was accomplished. The timing of establishment was good since a physical plant and equipment were available for immediate use by the State of Tennessee. Tennessee Junior College, the official title given to the newly established junior college at Martin, replaced Hall-Moody Junior College and took possession of all property, including land, buildings, and equipment, that had been owned by the former school. The development of Hall-Moody, because of its location, is an integral part of the sequence of events in the development of the Junior College and the Martin Branch. Predictions based upon surveys and population estimates and trends indicate that present facilities and institutions of higher education are insufficient to provide the education needs of the future. The General Assembly of the State of Tennessee has already passed legislation providing for the limitation of enrollment in State colleges of Tennessee. It is appropriate at this time an analysis of the University of Tennessee, Martin Branch, development be made. The development pattern of the past may indicate steps that need to be taken at the present time and in the future to provide adequate higher education for citizens of upper West Tennessee

41SM195A, The Browning Site

A surface collection of early 19 \u27 century historic sherds led to archaeological investigations in 2002 and 2003 at the Browning site (41SM195A) in eastern Smith County, Texas. My interest was whetted by mention in the original land abstract that the property had once been deeded to the Cherokee Indians. In all, a total of 6.5 cubic meters of archaeological deposits was excavated at the site, including 22 shovel tests and 10 1 x 1 m test units, and fine-screen and flotation samples were taken from a prehistoric midden deposit identified during the work. As a result, 1075 prehistoric and historic artifacts were recovered, along with new information about Woodland period archaeology in this part of East Texas. The initial shovel tests found, in addition to the historic component, a buried midden with evidence of Woodland period occupation. Based on the excavations, the midden covered approximately 500 square meters. The 19th century historic artifacts were found in the upper sediment zone, a brown sandy loam that was mostly gravel- free) covering the midden. The buried midden was a dark yellowish-brown gravelly loam that contained prehistoric pottery, animal bone, charred wood and nutshells, lithic materials, including lithic debris, flake tools, arrow and dart points, and ground stone tools. A calibrated radiocarbon date of A.D. 625 to 880, with a calibrated intercept of A.D. 685, was obtained on charred nutshell from 40-50 em bs in the midden zone. A series of Oxidizable Carbon Ratio (OCR) dates from the midden indicate that the midden began to from about A.D. 147, with dates of A.D. 357-815 from the main part of the midden, indicating when the Browning site was most intensively occupied in prehistoric times

Recombinational DNA Repair: The RecF and RecR Proteins Limit the Extension of RecA Filaments beyond Single-Strand DNA Gaps

AbstractIn the presence of both the RecF and RecR proteins, RecA filament extension from a single strand gap into adjoining duplex DNA is attenuated. RecR protein alone has no effect, and RecF protein alone has a reduced activity. The RecFR complexes bind randomly, primarily to the duplex regions of the DNA, and the extension of the RecA filament is halted at the first complex encountered. A very slow lengthening of RecA filaments observed in the presence of RecFR is virtually eliminated when RecF is replaced with an RecF mutant protein that does not hydrolyze ATP. These observations are incorporated into an expanded model for the functions of RecF, RecO, and RecR proteins in the early stages of postreplication DNA repair

Simulator Sickness Questionnaire: Twenty Years Later

The present study used simulator sickness questionnaire data from nine different studies to validate and explore the work of the most widely used simulator sickness index. The ability to predict participant dropouts as a result of simulator sickness symptoms was also evaluated. Overall, participants experiencing nausea and nausea-related symptoms were the most likely to fail to complete simulations. Further, simulation specific factors that increase the discrepancy between visual and vestibular perceptions are also related to higher participant study dropout rates. As a result, it is suggested that simulations minimize turns, curves, stops, et cetera, if possible, in order to minimize participant simulation sickness symptoms. The present study highlights several factors to attend to in order to minimize elevated participant simulation sickness

Micromechanics of fatigue in woven and stitched composites

The goal is to determine how microstructural factors, especially the architecture of microstructural factors, control fatigue damage in 3D reinforced polymer composites. Test materials were fabricated from various preforms, including stitched quasi-isotropic laminates, and through-the-thickness angle interlock, layer-to-layer angle interlock, and through-the-thickness stitching effect weaves. Preforms were impregnated with a tough resin by a special vacuum infiltration method. Most tests are being performed in uniaxial compression/compression loading. In all cases to date, failure has occurred not by delamination, but by shear failure, which occurs suddenly rather than by gradual macroscopic crack growth. Some theoretical aspects of bridging are also examined
