    No full text
    Recorded live at Southern Baptist Theological Seminary on May 20, 1996.An interview of G. Allen West about Professor R. Inman Johnson and his interview of Professor Johnson in 1984. Dr. West was a student under Professor Johnson in the 1930s at the Southern Baptist Theological Seminary. Dr. West discusses the life and character of Professor Johnson who died in 1991. He covered Johnson’s relationships with students, involvement in music and racial relations work in his retirement. Said Johnson was a "Southern gentleman, a Christian, a Baptist, a teacher, a musician, a vocalist, a humorist. He was an outstanding PR man, an outdoorsman, a hunter, a fisherman, a gardener ... this is Professor Johnson, the gentleman, the friend, the man who lived by the side of the road and became a friend to man." Much of the material for this presentation came from Professor R. Inman Johnson’s book "Of parsons and profs" and the Baptist minutes collection

    Compacted oxide layer formation under conditions of limited debris retention at the wear interface during high temperature sliding wear of superalloys

    For many applications, including power generation, aerospace and the automobile industry, high temperature wear provides serious difficulties where two or more surfaces are able to move relative to one another. It is increasingly the case that with for example, aerospace applications, demands for ever more powerful and efficient engines that thus operate at higher temperatures, conventional lubrication is no longer sufficient to prevent direct contact between metallic surfaces and consequent accelerated wear. One phenomenon that has been observed to reduce metallic contact and thus high temperature wear and friction is the formation of what are termed ‘glazes’, essentially layers of compacted oxide wear debris that becomes sintered together to form a low friction wear resistant oxide surface. This thesis studies the nature of the wear encountered with four different combinations of Superalloys, slid together using a ‘block-on-cylinder’ configuration developed for accelerated simulation testing of car engine ‘valve-on-valve-seat’ wear. Predominantly, Nimonic 80A and Incoloy MA956 were used as sample materials and Stellite 6 and Incoloy 800HT were used as counterface materials

    Panamericanismo y nación : La perspectiva de Samuel G. Inman

    No full text
    Panamérica es un término político utilizado en un ámbito diplomático más que un signo de identidad. Por tanto, no tiene el mismo peso simbólico de otros conceptos (como Latino, Ibero o Hispanoamérica). Sin embargo, las Conferencias Panamericanas de 1910 y 1923 coincidieron con la celebración de conmemoraciones relevantes (de independencia fundamentalmente pero también del Congreso de Panamá realizado por Simón Bolívar). Como mostramos en este trabajo, a través de la perspectiva de Samuel Guy Inman (estadounidense que estudió y participó en buena parte de dichos encuentros), las conmemoraciones tuvieron un papel menor y su incorporación en los debates fue utilizado para forzar a Estados Unidos a discutir temas pendientes en la agenda regional, como la Doctrina Monroe y la hegemonía de los Estados Unidos en la Unión Panamericana

    Marguerite Inman Davis: first progressive first lady of Virginia

    No full text
    Born to wealth, Marguerite Inman Davis (1870-1963), daughter of a New York cotton broker of Southern lineage, grew up in the best societies of Georgia and New York and studied piano in Bonn and Paris. After her marriage to Westmoreland Davis in 1893, she continued to travel extensively in Europe and the Orient. In 1903, after she and her husband purchased the 1,500 acre Morven Park estate in Loudoun County, Virginia, Mrs. Marguerite Inman Davis assumed the life of a hostess and pursued her talents as an equestrienne and gardener. As first lady of Virginia during World War I, Marguerite Davis consciously set an example for women·of the state and nation to enter war work. She volunteered, as president of the Woman's Munition Reserve, to sew silk bags and fill them with smokeless gun powder at Seven Pines outside Richmond. Later she helped save a peach crop from ruin during the war labor shortage. In the course of the Spanish influenza epidemic which swept Richmond between October, 1918, and November, 1919, she served as a volunteer nurse in the pneumonia ward of the John Marshall Emergency Hospital. Yet, while Marguerite Davis played the role of a modern woman and patriot, she also maintained the tradition of southern gentility and hospitality. Entertaining groups of soldiers, students, politicians, and suffragettes, she democratically made the people of the Old Dominion very much at home in the executive mansion during the Davis administration (1918-1922). From her husband’s defeat in the 1922 senatorial primary until her death, Mrs. Davis contributed generously to many philanthropic and social causes. Unable personally to work in the war effort of World War II as she had in World War I, Marguerite Davis donated two ambulances, several pedigreed Doberman Pinschers, and invested a large part of her husband's estate in war bonds. Throughout her life, Marguerite was generous in giving scholarships to deserving Virginia students. Mrs. Davis retired from public life after the death of her husband in 1943, and moved to her sister's home in Branford, Connecticut. She continued, however, despite her advancing age to attack the state of Virginia politics. Inflamed by the laudatory eulogies heaped upon Senator Carter Glass at his death in 1947, Mrs. Davis publicly condemned both Glass and the Byrd organization. In establishing the Westmoreland Davis Memorial Foundation, Marguerite Inman Davis displayed enlightened philanthropic views by providing munificently not only for ordinary scholarships but to make historic Morven Park an endowed center. She remained at Branford, Connecticut, until her death on July 15, 1963.Master of Art

    Overview of piezoelectric impedance-based health monitoring and path forward

    No full text
    In this paper we summarize the hardware and software issues of impedance-based structural health monitoring based on piezoelectric materials. The basic concept of the method is to use high-frequency structural excitations to monitor the local area of a structure for changes in structural impedance that would indicate imminent damage. A brief overview of research work on experimental and theoretical studies on various structures is considered and several research papers on these topics are cited. This paper concludes with a discussion of future research areas and path forward.This work was sponsored by the Department of Energy through Laboratory Directed Research Development, entitled “Damage Prognosis Solution”
