The Beta Subunit Determines The Nucleotide Specificity Of Atp-Specific And Gtp-Specific Succinyl-Coa Synthetases In Vertebrates., James Darwin Johnson

Theses and Dissertations

Two isoforms of succinyl-CoA synthetase (SCS) have been purified from breast muscle and liver in pigeon, one highly specific for adenine nucleotides (A-SCS), the other for guanine nucleotides (G-SCS), respectively. Nucleotide specificity studies demonstrated that A-SCS could not utilize guanine nucleotides and that G-SCS could not use adenine nucleotides. Enzymatic assays of tissue extracts detected both isoforms in kidney, heart, and brain, while only A-SCS was in breast muscle, and G-SCS in liver. Highly purified A-SCS and G-SCS each possessed the α and β subunits that are common to all previously purified SCSs. Characterization studies of the two isoforms by …

Cytotoxin Targeting Of Oxytocin (Ot) Receptive Cells: Ot Receptors And Salt Appetite., Trini Troy Vargas

Theses and Dissertations

The targeting of oxytocin (OT) receptive cells with a novel cytoxin (ricin A-chain oxytocin conjugated to oxytocin; rAOT) has revealed a potential role for OT in the osmolality-related inhibition of salt appetite seen in two model systems. The experiments in this study were designed to test the hypothesis that intraventricular (icv) treatment with rAOT results in the loss of [I 125]-OVTA binding sites in the central amygdala in these two model systems (Experiment 1: Mannitol Challenge; Experiment 2 PEG/Mannitol Challenge). Experiment 1 (Mannitol Challenge; produces hyperosmotic/hyponatremic conditions in the rat) and Experiment 2 (PEG/Mannitol Challenge; produces hypovolemic/hyperosmotic/hyponatremic conditions in the …

Jewish Exile And Immigration: Re-Imagining Home On The North Dakota Prairie, Jason Zevenbergen

Theses and Dissertations

From the memoirs of several Jewish homesteaders in North Dakota, one observes a series of binaries between Diaspora and homeland and between Jewish Orthodoxy and more liberal forms of Jewishness. The writers of these memoirs generally produce these binaries through two methods. First, the content they introduce in their stories reflects opposing categories of Jewishness, such as Orthodox and Reform Judaism, that significantly frame the nature of their relationships to their families, local community, and country. Second, when the writers transfer stories from their past into the contemporary moment, they juxtapose a previous self with their present self at the …

Communicating Through Photographs: A Guide For Public Relations Professionals, Carol Ann Desimine

Theses and Dissertations

The purpose of preparing this guide was to create a resource for public relations professionals to refer to when faced with the task of placing photographs in publications. The assumption is that most public relations professionals are not trained to think visually, partly because their education is focused on writing and virtually ignores aesthetics. Since readership surveys find that people prefer photographs over the written word, and that pictures capture attention quicker than headlines, it is essential that public relations people know how to use visuals to enhance a message. The primary research methods of this study were examination of …

Scan-It: A Computer Vision Model Motivated By Human Physiology And Behavior, John G. Keller

Theses and Dissertations

This dissertation details the development of a new computational vision model motivated by physiological and behavioral aspects of the human visual system. Using this model, intensity features within an artificial visual field of view are extracted and transformed into a simulated cortical representation, and a saccadic guidance system scans this field of view over an object within an image to memorize that object. The object representation is thus stored as a sequence of feature matrices describing sub-regions of the object. A new image can then be searched for the object (possibly scaled and rotated), where evidence of its presence is …

The Effects Of Thought Suppression On Later Recall Of Valenced, Self-Referenced Adjectives, Danial S. Sturgill

Theses and Dissertations

This study examined the effects of thought suppression on later recall of valenced material. According to Wegner's (1994) theory of ironic mental processes, effortful attempts at thought suppression result in an increased accessibility of the to-be-suppressed thought under conditions of high cognitive load. Participants (N = 180) received an induced-sadness manipulation before being asked to concentrate on associations between visual images (either a white bear or an brown rabbit) and 28 adjectives (14 positively-valenced, 14 negatively-valenced). After a five minute period of suppressing thoughts of one of the visual images, participants were asked to remember as many of the 28 …

Image Fusion Using Autoassociative-Heteroassociative Neural Networks, Claudia V. Kropas-Hughes

Theses and Dissertations

Images are easily recognized, classified, and segmented; in short, analyzed by humans. The human brain/nervous system; the biological computer, performs rapid and accurate image processing. In the current research the concepts of the biological neural system provide the impetus for developing a computational means of fusing image data. Accomplishing this automatic image processing requires features be extracted from each image data set, and the information content fused.
