Further inspection revealed that this mutant was a cell cycle mutant and cells in the mutant arrest during metaphase as early as the 5-somite stage (11.6 hours of development). A similar phenotype is seen in the Drosophila melanogaster cell cycle gene fizzy, known to be to be a homolog of the Saccharomyces cerevisiae gene, cell division cycle 20 (cdc20). CDC20 is an activator protein of the anaphase promoting complex/cyclosome (APC/C), an ubiquitin E3 ligase that is …

Recommendations For The Development Of New Hospital Guidelines Due To The Effects Of Antibiotics On Clostridium Difficile Colitis, Megan Kohsel

Honors Theses

Clostridium difficile colitis is an infection that causes inflammation of the colon and diarrhea. This can even lead to death in some cases. The incidence of this infection and its overall effects have been on the rise throughout the last twenty years as antibiotics have been prescribed more frequently. Therefore, it is necessary that the rate of C. difficile infection is lowered by improved guidelines for hospitals, so that fewer people are infected and also that fewer antibiotics are prescribed to avoid the infection with C. difficle.

Check-In Frequency With Friends On Location-Based Social Networks: A Look At Homophily And Relational Closeness, Jacqueline H. Vo

Dissertations and Theses

This study examines factors associated with the frequency with which users of location-based social networks (LBSNs) "check-in" with their "friends." In addition to a variety of control factors (i.e., sex homophily, race homophily, geographic proximity, length of friendship, and "friendship" type, including non-romantic friend, romantic partner, and family), the central factors of interest were users' background and attitude homophily with, and relational closeness to, their "friends." Results demonstrate that relational closeness and "friendship" type (i.e., romantic partner) were significantly, positively associated with "check-in" frequency.

Coyotes On The Web: Understanding Human-Coyote Interaction And Online Education Using Citizen Science, Zuriel Anne Rasmussen

Dissertations and Theses

Coyote (Canis latrans) numbers are increasing in urban areas, leading to more frequent human-coyote interactions. Rarely, and particularly when coyotes have become habituated to humans, conflicts occur. Effective education about urban coyotes and how to prevent habituation reduces conflict. Citizen science, in the form of online education, can be used to engage and educate city dwellers about urban coyotes. In this research, I explore Portland Metropolitan Area (PMA) residents' baseline experiences with, and attitudes toward, urban coyotes. Next, I investigate citizen science as a tool for education. Using the Portland Urban Coyote Project (PUCP), a citizen science project, as a …

Cold In-Place Recycling Characterization Framework For Single Or Multiple Component Binder Systems, Ben C. Cox

Theses and Dissertations

Cold in-place recycling (CIR) is a pavement rehabilitation technique which has gained momentum in recent years. This momentum is due partly to its economic and sustainability characteristics, which has led to CIR market expansion. When pavement network deterioration is considered alongside increasing material costs, it is not beyond reason to expect demands on CIR to continue to increase. Historically, single component binder (SCB) systems, those with one stabilization binder (or two if the secondary binder dosage is 1% or less), have dominated the CIR market and could be considered the general state of practice. Common stabilization binders are either bituminous …

Design, Synthesis, And Testing Of Bis-Corannulene Receptors For Fullerenes Based On Klärner’S Tethers, Peumie Luckshika Abeyratne Kuragama

Theses and Dissertations

The discovery of the new allotropic forms of elemental carbon (e.g. fullerenes and carbon nanotubes) introduced a novel motif in supramolecular chemistry based on dispersion interactions of curved networks of sp2 hybridized carbon atoms. Buckybowls, the curve-shaped polycyclic aromatic hydrocarbons, appear to be ideal candidates for molecular receptors to recognize fullerenes. Corannulene, the smallest and the best studied buckybowl, has been recognized as one of the important pincers in developing molecular receptors for fullerenes. The main goal of our research is to synthesize corannulene-based molecular receptors for fullerenes with high binding affinities with the use of the pincers preorganized on …

Conserving The Mississippi Gopher Frog (Lithobates Sevosa) Through The Use Of Assisted Reproductive Technologies, Katherine Michelle Graham

Theses and Dissertations

The Mississippi gopher frog (MGF, Lithobates sevosa) is a critically endangered amphibian which requires the use of assisted reproductive technologies (ART) to successfully reproduce in captivity. Several challenges to successfully breeding MGFs were investigated to improve reproduction in this species. Accurate identification of biological sex is a necessary first step to reproducing species, thus several non-invasive techniques for sex identification were compared in the weakly dimorphic MGF. Reliably obtaining eggs from female MGFs has also proved difficult, therefore, four exogenous hormone therapies were compared for their success to induce ovulation. Ultrasound imaging was used alongside hormone treatments to improve understanding …
