    • Hyperfine structure in the microwave spectra of the iodine fluorides iodine heptafluoride and iodine pentafluoride and of the weakly bound complex hydrochloric acid...nitrous oxide

      Shea, James Christopher, 1964- (The University of Arizona., 1989)
      A pulsed-beam fourier transform microwave spectrometer was used to measure the rotational spectra of iodine heptafluoride, iodine pentafluoride, and the weakly bound complex, HCl...NNO. For IF7, only five rotational transitions were observed, and no resolvable hyperfine structure was detected. Based on this data, the A, B, and C rotational constants were determined to be 1746(3) MHz, 1732.0(8) MHz, and 1553.0(2) MHz, respectively. The existence of a pure rotational spectrum confirms that this molecule undergoes polar distortions. Twenty-two hyperfine components of the IF5 spectrum were recorded. The B rotational constant for this molecule was determined to be 2727.421(3) MHz, and the quadrupole coupling constant was found to be 1069.35(13) MHz. Though the work is still in progress on HCl...NNO, nine transitions have been recorded. In addition, five transitions have been recorded for an apparent trimer species composed of HCl, NNO, and an as yet unidentified third species.
    • HYPERHOMOCYSTEINEMIA: GENETIC POLYMORPHISMS AND RISK OF CORONARY ARTERY DISEASE

      Hayashi, Satomi; Wung, Shu-Fen; Wung, Shu-Fen; Ritter, Leslie; Merkle, Carrie (The University of Arizona., 2003)
      This comprehensive literature review focuses on homocysteine, gene polymorphisms related to homocysteine metabolism and their relationship to coronary artery disease (CAD). Currently, CAD is known as a multifactorial genetic disease, resulting from complex interactions between genetic factors and various environmental influences. In recent years, tremendous knowledge about the hereditary aspect of CAD has been gained, including an understanding of CAD as a multifactorial condition resulting from complex interactions between genetic factors and various environmental influences that trigger, accelerate, or exacerbate the disease process. Among the risk factors for CAD, hyperhomocysteinemia has been recognized for its relation to atherosclerotic alterations in the vessels. In addition, gene polymorphisms in methylene - tetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR), methionine synthase (MS), and cystathionine ß - synthase (CßS), which are involved in homocysteine metabolism, have been identified as a result of advances in genetic research related to cardiovascular pathophysiology. In particular, the results of recent salient studies have provided evidence of significant association of these genetic polymorphisms and CAD in Japanese and part of European populations but not in the United States, Australian, and part of European populations. This disparity may explain the variation of prevalence of CAD among different populations. Potential gene - environment interactions may elevate homocysteine levels and increase the risk of CAD. This discussion includes the pathogenesis of hyperhomocysteinemia, definitions of normal and elevated homocysteine levels, the physiological background of homocysteine metabolism, polymorphisms of genes involved in homocysteine metabolism from the perspective of CAD risk, and implications for nursing practice based on emerging information regarding hyperhomocysteinemia as a risk factor for CAD. Findings from these recent studies are important for nurses, clinicians, and researchers to be able to incorporate cardiovascular genetic information in their practice and research and provide more adequate care to reduce the risk for CAD and improve patient outcomes.

    • Hypoxic/aglycemic stress alters blood-brain barrier transport systems

      Davis, Thomas P.; Hom, Sharon; Larson, Douglas F.; Sethi, Gulshan K. (The University of Arizona., 1999)
      Increased cerebrovascular permeability is an important factor responsible for the development of ischemic brain injury and edema formation associated with stroke pathophysiology. Extensive studies of stroke research have centered primarily on the response of neurons and astrocytes to hypoxic or ischemic insult. The response of cerebral capillary endothelial cells to hypoxia is not well understood. Damage to the blood-brain barrier (BBB) induced by hypoxia/ aglycemia may influence BBB permeability and transport mechanisms, thereby contributing to the development and severity of stroke. The development of a low flow in situ brain perfusion model was used in this study to illustrate the effect of ischemia/hypoperfusion coupled with hypoxia and aglycemia on BBB transport mechanisms. Three transport markers were used in various combinations of low flow, hypoxia, and aglycemia to characterize BBB transport mechanisms. The results of this study suggest BBB basal permeability is not com promised during low flow perfusion, however in the presence of hypoxia/ aglycemia, a significant change in BBB permeability is observed among the three transport markers. Thus, the effects of ischemia as produced by low flow, hypoxia, and aglycemia alter BBB permeability due to the probable impaired action of many transport systems under these adverse conditions.
    • I Am The Space Where I Am: An Arts-Informed Autoethnographic Inquiry on Place-Conscious Education In The Community

      Hochtritt, Lisa; Miller, Taylor Kathryn; Sharma, Manisha; Reid, Natasha (The University of Arizona., 2016)
      This thesis investigates how my representations of experience through arts-informed autoethnographic research are significant in establishing the pedagogical nature of place. I seek to understand how place-conscious education in a community setting can encourage students' relationships with the spaces they inhabit and lend to a more just learning environment. Many educative tools are provided and analyzed which are derived from wayfinding and psychogeographic methods. Data was collected over two months throughout the Summer of 2015 while participating in the Onward Israel service learning program in Israel and Palestine. My digital photographs and excerpts of stream-of-consciousness style poetry serve as the data set to illuminate the rich sensory encounters and art making processes indicative of experiential learning. This context-driven artwork encourages questions and dialogue about sociopolitical conflict and wars, migration and occupation. It is concerned with physical as well as psychological borders, checkpoints and boundaries. I utilized poetic and photographic inquiry as well as cognitive mapping to explore how concepts of travel are intricately linked to practices of self-reflexivity, community building and alternative curricula development outside of the formal classroom setting. This qualitative data is not a strictly defined set of interviews or statistics. Instead, vignettes of a more totalizing experience can be extracted, analyzed, dissected and/or rearranged. It is an exploration of identity, agency and untraditional ways of knowing the self/Other. I underscore how new pathways and possibilities for teaching emerge from a greater acceptance and validation of experiential knowledge and an attuned consciousness to place.
    • “I Can’t Dance in Two Weddings”: Marriage as an Articulation of Emerging and Transforming Fractures in the Iraqi Ezidi Refugee Community in Germany

      Green, Linda; Stuewe, Allison; Hudson, Leila; Betteridge, Anne (The University of Arizona., 2018)
      As a lens for analyzing the frictions in the Iraqi Ezidi refugee community in Germany, I consider marriage as a lived daily reality, an idealized concept, and ritualized life cycle event. I evaluate the ways tensions between Ezidis and between Ezidis and non-Ezidis are enacted through these myriad aspects of marriage. In addition to exploring the particular ways these tensions have emerged, been strengthened, or transformed within the Ezidi refugee community and between non-Ezidi others, this paper argues that Ezidi refugees are uniquely situated to highlight the loss and precarity created by migration even when the community in question has been bestowed a certain amount of privilege vis-à-vis other migrant groups inside of Germany and in other countries. The numerous topics that are increasingly dividing the community include marriage rules, traditional authority structures, caste tensions, connections to Kurdish culture and politics, thoughts on the influence of Islam on Ezidism, and what it means to be a “good” Ezidi. The fractures that emerge around these topics divide the community along region of heritage, generational, gender, and class lines. In analyzing these fractures, I emphasize the overwhelming sense of instability in the Iraqi Ezidi refugee community and argue that this instability is enhanced by the political acts of the German government and the governments or leaders from back home, including but not limited to the Kurdish political parties and the Iraqi central government.
    • I relate to the sense of not belonging: Native American perspectives of homelessness

      Stauss, Joseph; Mortensen, Margaret Ann, 1972- (The University of Arizona., 1998)
      Responses of ten Native American men, who reported being homeless for at least six months, waiver slightly from the hypothesis that their concept of home denotes community, family, and an indigenous connection to the land. However, they did strategically cope to create home-like atmospheres. Direct answers show that home provides basic necessities, safety, and emotions of well-being, like belonging. Scrutiny of the complete contexts of these men's lives show that friendship often replaced a lack of family. Some participants referred to an indigenous connection to the land and to home as being more than one place, including a natal reservation. Adoption and a period of time away from culture, an uprootedness, also characterized these lives. Researcher recommendations include a permanent wet/dry residence, a camping area, and provisions for more culturally specific homeless services.
    • "I've needed a friend my whole life". Voices offormer gang members: An ethnodrama

      McCammon, Laura A.; Roberts, Christine Elizabeth (The University of Arizona., 2002)
      This thesis set about to achieve three goals. First it discusses street gang research, assessment of the gang problem, and in particular the forces that push and pull American youths into the street gang lifestyle and the gang member experience. Second, it explores how alternative forms of data presentation, such as ethnodrama, blur the boundary lines between art and scientific research and demonstrates that the embodiment of human experience through artistic means enhances our understanding of the gang problem and creates context. Third, it includes an ethnodrama text constructed from qualitative interviews of three former gang members, in support of narrative inquiry research methods, and illustrating how three young men were drawn into the gang lifestyle, what they experienced by being in a gang, and the factors that helped them to leave the gang and lead them to make positive changes in their lives.

    • IC defect detection using color information and image processing

      Schowengerdt, Robert; Yang, Hsien-Min, 1957- (The University of Arizona., 1988)
      Most current commercial automated IC inspection systems use gray-level or binary images for IC defect detection in spite of the fact that color permits defect detection where gray-level information is insufficient. Three color image processing techniques including the spectral-spatial clustering, principal components, and hue-saturation-value (HSV) color features have been investigated to evaluate the usefulness of color for IC defect detection. The AMOEBA spectral-spatial clustering algorithm, an un-supervised color segmentation approach, with a sequence of image processing procedures resulted in segmentation results with high accuracy and discriminated successfully an isolated and homogeneous defect with an unique color signature. The principal components transformation and the HSV color features, two color enhancement/separation algorithms, have proven useful for enhancing and isolating weak spectral signatures in the defect regions. The results of this investigation into the use of color are promising.
