    • Buffelgrass Expansion Rate and Dispersal Type on Recently Invaded Barry M. Goldwater Range of Southwestern Arizona

      Fehmi, Jeffrey S.; Damery-Weston, Jaron; McClaran, Mitch; Whittle, Richard (The University of Arizona., 2016)
      Land managers have struggled to develop successful control strategies to address buffelgrass invasion in the Sonoran Desert. Two important variables for control strategies are dispersal type and patch expansion rate (i.e. satellite or invasion front). We investigated these variables along a highway invaded within the last 10 years located south of Gila Bend, Arizona, USA. Dispersal type was calculated by documenting the location of each buffelgrass individual along a 16 km stretch of highway and using an average nearest neighbor analysis in ArcMap 10.2.2. Thirty-six patches were monitored for four years along a 56 km stretch of highway 85 by documenting the outlines of each patch. Dispersal type registered as satellite dispersal (i.e. clustered on the Nearest Neighbor test), z-score = -47.2, p < 0.01. Patch expansion exhibited a median doubling time of 0.81 years. The results of the dispersal type analysis represent an opportunity to enhance control strategies, by targeting buffelgrass satellites and theoretically reducing patch expansion exponentially. The patch expansion rates for buffelgrass were faster than found in past research, giving land managers a clearer understanding buffelgrass patch expansion behavior.
    • Building an expert system shell for design model synthesis in logic programming

      Rozenblit, Jerzy W.; Huang, Yueh-Min, 1960- (The University of Arizona., 1987)
      This thesis implemented a prototype of an expert system shell for support of engineering design activities in the way of logic programming. The development of the system is based on the theoretical framework for knowledge-based system design and the formal modeling concepts. Under the above methodologies, two knowledge representations, production rule system and system entity structure, are incorporated into the knowledge base for figuring design structures. Here the production system scheme is employed for synthesis of design models represented in the system entity structure. The whole system is coded in Turbo Prolog and a specific domain knowledge, namely a local area network, is currently used as a testbed environment.
    • Building Integrated Water Efficiency Strategies that Generate Energy and Enhance Human Thermal Comfort

      Chalfoun, Nader V.; Selim, Kareem Hassan; Chalfoun, Nader V.; Blowers, Paul; Moeller, Colby; Fredrickson, Mark (The University of Arizona., 2014)
      Building integrated water efficiency strategies can generate energy or reduce the energy consumption of the building. Solar and wind are two natural forces that are commonly used to provide energy to buildings today; water, on the other hand, is usually ushered off site and not utilized to its full potential. The question is how to find a way to reduce the energy used to get the water needed for the building, because water is an important aspect to care about and save. This will require several methods and strategies in order to find the best and most efficient way of doing this. This thesis is proposing a smarter way of utilizing one of earth's most precious resources as a guideline for the designer to conserve energy by using a water harvesting system, grey water system and reuse, water use reduction, water heating and cooling. Concentrating more on generating energy or reducing energy consumption using water by fuel cells, solar water heater, photovoltaic thermal and algae. Finally, the proposed method is to generate energy using algae, while growing it to the building's façade facing south. Algae panels use water and sunlight to grow, then are harvested in the building to generate enough energy to power it. Algae is the most known source of energy now and only used for industrial purposes, however applying it to a research building called Engineering Innovative building got 134 feet south façade, will be a huge source of energy to power it up. It also can be used for educational purposes to study.
    • Building Reuse: Beyond Preservation, Towards Policy

      Lovato, Michael J.; Jeffery, R. Brooks; Nequette, Annie; Bartlett, Susan (The University of Arizona., 2008)
      To be truly sustainable, a society must maximize the use and reuse of its existing resources. Yet the economics of the construction industry are designed to encourage the construction of new buildings as quickly and as cheaply as possible, and the demolition of existing buildings just as quickly. In order to achieve the levels of sustainability deemed essential by many of our nation’s leaders, the vast resource that our existing building stock represents can no longer be ignored, regardless of lack of historic signifi cance, perceived aesthetics, or energy effi ciency. Th is thesis summarizes and assesses the eff ectiveness of existing policies established in the interest of preservation, sustainability, and economic development that provide a strong framework for building reuse. Th is thesis outlines a feasible building reuse policy, conceived as largely independent from, but with the potential for, far-reaching benefi ts for preservation, sustainability, and economic interests.

    • A Built Environment with Architectural Parameters in Sustainability That Mitigates the Onset of PTSD in High Armed Conflict: Physiological, Cognitive, Psychoanalytic, And Social/Behavioral Stimuli to Induce Cognitive Processing for Self-Healing

      Chalfoun, Nader; Havelka, Heather Leigh; Chalfoun, Nader; Moeller, Colby; Youssef, Omar (The University of Arizona., 2018)
      Post-Traumatic Stress Disorder (PTSD) was first recognized in veterans of war and called shellshock, and in later years defined by numerous other names. Since 2001 the rate of PTSD within Veterans has increased to the same percentage as that found in the Vietnam War, and I’ve questioned, “what is being done for them on an environmental level”? How is the built environment benefiting them by reducing forms of stimulation that “triggers” or induces unstable behavior? With extensive research the clear answer was that nothing is being done within our built environment, aside from a few guidelines to design to lessen negative impacts. Equally, nothing out in high armed conflict nor in overseas installations that provide rehabilitation care units to wounded warriors are bridging therapy done out there to that done in the United States. The fact is that there is a lack of connection and familiarity with a “sanctity” out in warfare for those with PTSD and this is what inspired this thesis and the innovative design it discusses. A built environment with sustainable architectural parameters will not only allow a “sanctity” to be undetectable and a secure unit for self-rehabilitation as a parallel helper to other forms of therapy for PTSD in conflicted areas, but will equally create an intimacy with the built environment that leads to personal security to enable one to take the necessary steps to continuing rehabilitation after returning home to the United States.
    • The bulk modulus of hydraulic fluids at elevated temperatures

    • Burakku Metaru (ブラック ・メタル): Japanese Black Metal Music and the ‘Glocalization’ of a Transgressive Sub-Culture

      Smith, Nathaniel M.; Coulombe, Alexander Paul; Ren, Hai; Pinnington, Noel J. (The University of Arizona., 2018)
      This thesis will demonstrate how Black Metal music became established in Japan, how it evolved, and how musicians situate themselves in a globalized form of community. It is a study of how Japanese Black Metal functions in the tensions between globalization and localization, a term called “glocalization” (Victor Roudometof 10). Japanese Black Metal is globalized around a set of rules and ideas, a term Deena Weinstein uses to describe Heavy Metal music called “codes” (Heavy Metal the Music 100). Additionally, as this music is localized, it reveals how many Japanese musicians express uniquely cynical viewpoints of religion and established authority using these globalized codes. Due to its anti-Christian and brutal history in other countries, Black Metal is seen as transgressive against mainstream society. Through electronic ethnographic research with Japanese Black Metal artists, this thesis finally examines how Black Metal is at once desirable yet also transgressive in Japanese society, a country with a comparatively low population of Christians.
    • Burden of illness, resources, and quality of life in persons with rheumatoid arthritis, persons with other arthritic conditions, and persons with systemic lupus erythematosus

      May, Kathleen M.; Chiang, Hui-Ling (The University of Arizona., 1995)
      The purpose of this secondary data analysis was to investigate the difference in burden of illness and resources and relationships among burden of illness, resources, and quality of life in persons with rheumatoid arthritis, persons with other arthritic conditions, and persons with systemic lupus erythematosus. In burden of illness there was a significant difference in number of years ill, dependency, and uncertainty among the three groups. There was no difference in resources among the three groups. Except for disability payments and having attended self-help classes, there was a negative relationship between burden of illness and resources in persons with rheumatoid arthritis, persons with other arthritic conditions, and persons with systemic lupus erythematosus. A negative correlation was found between burden of illness and quality of life. Except for disability payments, there was a positive correlation between resources and quality of life.
    • Burrow selection by burrowing owls in an urban environment

      Mannan, R. William; Estabrook, Tracy Starr (The University of Arizona., 1999)
      I surveyed parts of Tucson, Arizona to determine numbers of burrowing owl (Speotyto cunicularia) burrows present, identify characteristics associated with burrow sites, and assess reproductive success. I measured habitat characteristics at 48 winter, 58 breeding, and 48 random burrows. Random burrows were closer to perches (P) and farther from wash banks (P) than were active burrows, and had smaller entrance dimensions (P). Winter burrows were farther from human activity than were breeding burrows (P). Active sites had less total vegetation, and less visual obscurity than did random sites. Owls may have selected open sites to facilitate detection of predators or prey. Urbanization sometimes created conditions which appeared to attract owls, but also destroyed burrows. An average of 2.31 young fledged from 116 active burrows during 1997-1998. While comparable to other studies of burrowing owls occupying urban environments, this was lower than rates typically reported for the species.
