    • Early conservation by the Arizona Federation of Women's Clubs from 1900 to 1932

      Johnson, Sandra Jeanne, 1968- (The University of Arizona., 1993)
      Women have been historically written out of human achievement. This is especially true in organized conservation. Historical analyses of the Progressive conservation era and the period following to the New Deal have understated women's organized participation in conservation. Through an analysis of Women's Clubs' records, newspapers, and magazines from 1900-1932, Arizona clubwomen's activities regarding natural resources are examined. The clubwomen are found to have been mutually and simultaneously supportive of conservation, preservation, civic improvement, nature study, and recreation--antagonistic issues at differing times. They reconciled those conflicts by advocating management solutions based upon resource renewability. Behind a shield of patriotism, maternalism, and housekeeping, the clubwomen used resource conservation to encourage a healthy future for humans and the environment. Conservation also served to advance their status as women through community service and self-education.

      The purpose of this clinical project is to invent a new Pap smear collection instrument and describe beginning research that is intended to establish an increased endothelial cell yield with intact nuclei that will lead to increased sensitivity and specificity of Pap smears with the use of this new instrument.
    • Early embryos of dams of heat stress

      Johnsen, Suzanne Louise, 1960- (The University of Arizona., 1989)
      Increased environmental heat causes early embryonic death before implantation. This study was designed to examine tissues of dams exposed to environmental temperatures of 36°C and to examine 72 hour old embryos from these dams. Results showed adult mice exposed to heat stress had significant changes in liver morphology with hepatocyte swelling and vacuolization of the cytoplasm, organelles in the hepatocytes were displaced next to the cell membrane. After 48 hours of recovery from heat stress, liver morphology appeared normal. Embryos from heat stressed dams had delayed development indicated by increased 2alpha helical cellular inclusions. Embryos responded differently to different fixation techniques indicated permeability changes in either the zona pellucida or cellular membranes. Litter size or pup survivability from heat stressed dams allowed to recover indicated changes seen at this point were reversible
    • Early Native American women writers: Pauline Johnson, Zitkala-Sa, Mourning Dove

      Stout, Mary Ann, 1954- (The University of Arizona., 1992)
      Turn of the century Native American women's published writing is examined for the elements which presage contemporary Native American women's writing. In particular, three writers' works and biographies are examined in order to determine why they wrote, how they wrote and what they wrote. Pauline Johnson, Zitkala-Sa and Mourning Dove made early contributions to the field of Native American women's literature.
    • Early papers of Alfred Adler: The physician as educator and sexual problems in child rearing

      Williams, Ursula Hertha, 1942- (The University of Arizona., 1990)
      The first article, The Physician as Educator (1904), discusses the misconception parents and educators hold regarding child-rearing practices. Both believe they must continually try to mold a child according to their perceived ideal. Alfred Adler discusses the futility of such a notion and emphasizes that parents and educators can only develop or hamper children's natural tendencies, or better yet, direct them toward cultural goals. Adler feels that only the educator or physician, who has overcome his/her own shortcomings will be capable of developing the child's potential and reveal the healing power in the patient. The second article, The Sexual Problem in Child Rearing (1905), points to the importance of using children's sexual awakening for educational purposes. He warns of the dangers of sexual precocity and perversity caused by faulty upbringing, but states that sexual perversity can be cured through love.
    • Early parental death and its effects on the establishment of intimate relationships in adulthood

      Kirshenbaum, Leah Sharon, 1960- (The University of Arizona., 1993)
    • The early philosophy of George Bernard Shaw as evidenced in his serial novels

    • Earth dam seepage analysis with a programmable calculator

      Hutchison, William Ray. (The University of Arizona., 1983)
      A model was developed for the Texas Instruments Company TI-59 programmable calculator for estimation of seepage from a reservoir. The model, DAM SEEPAGE, separates flow through the dam and flow under the darn by assuming that the boundary between the dam and foundation is a streamline. The algorithm used is based on Darcy's law, Dupuit's assumptions, and Bear's hydraulic approach. DAM SEEPAGE was applied to three situations, two proposed dams in eastern Montana and one existing dam in central Oklahoma. The two proposed dams were compared on the basis of seepage loss. The existing dam, a well-documented site, was chosen to check the accuracy of DAM SEEPAGE. The results of the study are within 2 percent of previously modeled results and within 13 percent of previously measured results.
    • Earth fissures in the Stewart area of the Willcox Basin, Cochise County, Arizona

      Anderson, Steven Robert. (The University of Arizona., 1979)
      Large amounts of ground water have been pumped from alluvial deposits in southern Arizona basins since the late 1940's. Significant declines of ground-water levels have occurred in some of the basins. Ground subsidence and earth fissures, believed to be related to the large declines, have been observed. Striking examples of the earth fissuring phenomenon occur in the Stewart area of the Willcox basin. Water levels have declined more than 100 ft (30.5 m) in the past 30 years due to agricultural pumping. Subsidence of 1 to 2 in (3.3 to 6.6 ft) has been recorded near the area of maximum water-level decline. Earth fissures associated with the water-level declines and subsidence have appeared at the basin floor margins near the Winchester Mountains, the Circle I Hills, and the Spike E Hills. The fissures occur in areas where alluvial sediments come into contact with Pleistocene lacustrine clays. Dense mesquite forests, with some unusually large members (some of which seem to be dying), commonly mark the boundaries. Two types of fissure patterns, semipolygonal to polygonal and semicurved to linear, are found intermixed in the Stewart area. The fissures in polygonal patterns appear narrower and shallower than linear fissures. The polygonal patterns suggest that some fissures may be due to horizontal contraction of clayey sediments. Some linear fissures may be the result of differential subsidence.

    • Earth Integration and Thermal Mass (for Global Energy Use Reduction)

      Wright, Jim Allen (The University of Arizona., 2016)
      As the rest of the world under development catches up economically with the developed nations, adoption of western tastes is projected to lead to enormous increases in energy use. Specifically, air conditioning use within countries with low saturation rates and high cooling degree rates (India and China) have a potential demand of up to 5 times that of the U.S. market. This growth in HVAC (Heating Ventilation&Air Conditioning) means billions of tons of increased carbon dioxide emissions and trillions of dollars in investment in electricity generation and transmission infrastructure.If there is adoption of Earth sheltering and integration design within these geographical areas, then it might be possible to mitigate the need for such high increase in electricity demand.Ultimately, an estimate of how much quantifiable impact wide adoption of earth integration can have in the regions in question needs to be calculated and compared to projected energy demand if things continue as they are. To do so, parameters need to be determined to see how much of the future air conditioning demand can be met through thermal mass/earth integration. That is, how much future energy demand can be avoided through earth sheltering? To do so:1-Determine what areas account for the greatest projected demand in future air conditioning use.2-See how much of the projected demand can be met through Thermal Mass and Earth Integration (T.M./E.I.) within these areas.3-A design/energy modeling exercise showing proper use and implementation of Earth sheltering within our local climate will be carried out to prove effectiveness of varied strategic thermal mass applications.4-Compare the relative savings of different levels of Earth Integration to arrive at an average overall savings if universal adoption takes place.Top-down approach to energy savings (HVAC efficiency) is not enough to offset projected adoption and its impact on the local and global environments. Energy efficient design is necessary to deal with as much of the increase in projected demand as possible. The use of earth as a building material can be a powerful tool in the fight against increasing energy demands and accompanied destructive environmental effects and needs greater consideration and adoption.
    • Earth orbiting objects observed by the infrared astronomical satellite

      Dow, Kimberly Lynn, 1963- (The University of Arizona., 1992)
      A systematic search (Dow and Sykes 1988) for cometary dust trails in the Infrared Astronomical Satellite (IRAS) Sky Brightness Images (1988) resulted in the discovery of 466 sources (Dow et al. 1990) that are not in the IRAS Point Source Catalog (Version 2 1988) or in the IRAS Small Scale Structure Catalog (1988). Nearly all of the sources that were found are best explained as artificial satellites or pieces of Earth orbiting debris. This study addresses two questions. To what degrees have the Sky Brightness Images been contaminated by orbital debris? Second, can valuable information concerning the thermal characteristics of these sources be obtained by suitably analyzing IRAS data? Fifty-four sources, covering a range of positions and observed fluxes, were selected from the main sample to determine their angular motion, flux density and color temperature distributions. Four of these objects were correlated with known artificial satellites. (Abstract shortened with permission of author.)
