Phenotypic Evolution of Circadian Rhythms in Arabidopsis thaliana

Stephanie Wakefield
Circadian rhythms are internal, repeating rhythms that can be set by environmental inputs such as temperature and light; because the diurnal cycle on earth is close to 24 hours, circadian cycles close to 24 hours are thought to be adaptive. I tested whether circadian rhythms evolved in the manner predicted, such that genotypes with period lengths greater than or less than 24 hours are at a selective disadvantage. I assayed 80 genotypes in total: 40...

Creation of a Recombinant Bacteriophage to Express Beta-Galactosidase

Catherine Swedberg & Heather Talbott
Human illness caused by the consumption of food contaminated with pathogenic bacteria is a worldwide problem that requires new detection methods to solve. The use of reporter bacteriophage as a device for detection of food-borne pathogens provides a promising new method to distinguish contaminated food and therefore prevent humans from infection. Creating a reporter bacteriophage requires modifying a bacteriophage to carry a reporter gene, which is produced during infection, allowing for rapid detection. A reporter...

Egyptian Feminism's Changing Relationship with Western Feminism

Ann Johnson
This research in progress examines how Egyptian feminism interacts with Western feminism. I hypothesized that a majority of Egyptian feminists would view Western feminism as a hindrance to "indigenous" feminism and therefore resist it. For example, some might feel that Western feminism places Egyptian women in a "victims" category, and therefore, reject it as a model of feminism in Egypt. Methods include identifying Egyptian women's organizations and literature for analysis. A historical literature review compares...

Sunrise Alarm Clock for the Hearing Impaired

Jim Follum
The Sunrise Alarm Clock is a device designed to be more effective than standard alarm clocks and more pleasant than specialty devices in waking the hearing impaired. This is accomplished with the inclusion of visual, physical, and audio alarms. The visual alarm stimulus is created by manipulating the light output of a bedside lamp to mimic the sunrise. This is achieved by varying the duty cycle of a pulse width modulated signal supplied through a...

The 5 meter diameter Big Spring in Hot Springs State Park, Thermopolis, Wyoming, has a 1-1.5-meterr outflow channel, 150 meters long to the first cooling pond. The average rate of flow is 14 million L/day at a temperature of 51-53°C, and is geologically controlled by an east-west trending fault. Fourteen sites are placed at 10 meter intervals from the source spring, except were the channel is dissected by the park road. The pH, temperature, and...

Testing for the Time Dependent Transition from a Rates Across Sites Model to a Covarion Model of Protein Evolution

Makayla Tisdell
Protein-coding gene sequences typically evolve constrained by the requirements for a protein to fold into its three dimensional structure. These constraints can dictate evolutionary rates at different sites, where residues in the hydrophobic core of a protein typically evolve more slowly than those on the surface. The exceptions to this are surface residues involved directly in functions of the protein such as binding, which are also conserved. A gamma distribution of rates across sites is...

The system has two components: the first is the system as it relates to the coal mine in question and all the information that is necessary to implement this system at the coal mine. The second component is a...

Creativity in Adaption: Where the Wild Things Are

Eric Lihammar
Where is place for wildness in our world? In Maurice Sendak's Where the Wild Things Are, first published in 1963, the character Max creates a space in the confines of his bedroom where being wild is not shunned but celebrated. In 2009 director Spike Jonze produced a film production of the book. The purpose of this study is to examine the thematic and visual adaptations involved in converting a story from one medium to another....

Stability of Motor Behavior Among Different Language Conditions

Elisabeth Boersma
Purpose: This study examines the relationship between an individual's language and motor production abilities. Understanding the bidirectional influence between language and motor ability is important for understanding basic theoretical processes underlying assessment and treatment programs. This feasibility study examines whether physiologic measures can detect differences in motor behavior among productions of high- and low-frequency words and their non-word, same syllable, counterparts. Method: Participants produced ten repetitions of 8 high-frequency real-words and their 8 non-word counterparts,...

Verifying Gastric Tube Placement in the ED

Danielle Pantoya
The use of nasogastric and orogastric tubes are a standard practice in Emergency Departments that require verification of placement into the stomach prior to initiating any form of treatment to minimize the risk of an adverse event. Pulmonary complications are the main risks associated with gastric tube insertion as the tube could be accidently placed in the tracheobronchial tree. Research was conducted to assess the reliability of the bedside verification methods of pH strips and...

Land for Livelihood or Profit?: Land Grabbing in Latin America

Caitlyn Skavdahl, Ryan Kennington & Christal Rohan
The act of land grabbing, or the purchase of large amounts of land by state and/or large corporations has been very prevalent in recent years in the developing world, particularly in Latin America. Populations, such as indigenous groups and afro-descendants, are extremely marginalized because of the effects of land grabbing. Consequences including reinforced income inequality, forced migration, and loss of territorial claims are occurring in countries such as Bolivia and Brazil. This practice has ties...

Compositional Techniques that Portray Characters, Ideas, or Emotions in Oboe and English Horn Repertoire

Kathryn Thayer
Using music to portray an idea or reflect on an emotion or character is a long-standing idea. An individual is capable of recognizing these qualities, even without being classically trained in music. In a movie, certain musical styles and techniques may predict ominous events. We have heard music that makes us feel sad; or happy. We all have a reason why certain artists or songs appeal to us, while others may not. Similarly, composers can...

Irish Oral Tradition

James Bland
Stories define culture through the villains and heroes. In a given culture or identity, stories prepare their audience by showing what to expect. Heroes exemplify positive traits to be mimicked, and villains and obstacles offer warnings for future challenges. The tone of stories, their length and their moral all vary depending on the medium, culture, and audience. The study of "stories" is separated from mass media by the academic community, and often by the general...

Dominant Negative Inhibition in Prion Protein

Arla Mistica
A prion is a non-conventional pathogen that consists solely of the infections isoform of prion protein (PrP-SC). Prions do not have any nucleotide genome but it causes lethal neurodegenerative diseases including Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (BSE) in cattle, and chronic wasting disease (CWD) in cervids. Prion infections occasionally pose threat to human health, for example, BSE in Europe and CWD in North America, whose zoonotic potential is still not fully understood....

This research project attempted to optimize the Nafion membrane fuel cell and compare the electrical output of microfluidic fuel cells with external and deposited electrodes. There were three objectives to this research: first, test all the fuel cells using the membrane preparation technique...

Ethnicity, Family, and Religion as Cultural Barriers among GLBTQ Students in the Rural College Community

Andre Fleak, Carie Vodopich & Maya Martinez
Research h as shown that classifications such as gender, ethnicity, race, age, sexuality and class have an impact on marginalization of individuals. Marginalization automatically places an individual in a position of being labeled as different. Any classification or other component of a social category has the power for inclusion and exclusion. We believe that marginalization is a result of various cultural barriers that affect minority populations, specifically the Gay, Lesbian, Bisexual, Transgendered, and Queer (GLBTQ)...

Influence of Photoperiod on Reproductive Success in House Sparrows

Rachel Bernard
Many features influence reproductive success, and discerning the importance of specific features requires the ability to control and modulate variables independently. Previous studies have indicated that the amount of light that an animal is exposed to each day (photoperiod) is an important factor in determining reproductive success. Songbirds are ideal subjects for these studies because they are seasonal breeders, with breeding only occurring in the spring and summer. To modulate the photoperiod independently from the...

Synthesis and Evaluation of anti-Nonspecific Binding Coating in Microfluidic Devices for ELISA Bioassays

Melissa J. Gelwicks
A common ELISA (Enzyme Linked Immunosorbant Assay) method for detection of biomolecules utilizes antibody coatings on surfaces that bind specific antigens. An enzyme-antibody conjugate that also binds to the antigen is then added, followed by a substrate that is converted by the enzyme to a detectable product. The sensitivity and reliability of these assays may be significantly reduced by the phenomenon of non-specific binding (NSB), in which the enzyme-antibody conjugate binds not only to the...
