With climate change and warming temperatures, ice cover duration in lakes across the world is becoming shorter. Duration of ice cover is tightly linked to oxygen concentrations at lake bottoms, with longer periods of ice cover associated with lower oxygen concentrations, which are detrimental for biological processes and food web interactions. I researched how this […]
B08-P: A Morphometric Analysis of Leaf Shape Responses to Abiotic Stress
Soil salinity causes an estimated $27 billion in agricultural losses every year, and these losses are predicted to be exacerbated by climate change. Brassica rapa is an important oil seed and vegetable crop that includes leafy greens such as bok choy. How B. rapa reacts to abiotic stresses such as soil salinity could greatly affect […]
A13-T: Using Diffuse Reflectance Spectroscopy (DRS) to Observe the Development of Pressure Injuries
Pressure Injuries are a major concern in medicine, yet their origins and pathologies are relatively unknown. The origins of these issues are continually studied but they are relatively unknown and cost the healthcare industry millions of dollars each year. Low-cost alternatives include optical techniques, which have previously been used to study tissue sample compositions and […]
C21-P: Quantifying Groundwater and Surface Water Interactions in the Four Mile Creek Alluvial Buried Aquifer
Many municipal water supplies come from groundwater pumped from wells that are set near surface water to take advantage of induced infiltration. By inducing surface water to enter the groundwater system, drawdown in the wells is minimized and the pumping capacity is increased. There are two potential problems that can result, however. First, there is […]
A11-P: The Effects of Ocean Acidification on the Seafood Industry and the Implications on Human Health
Over the past 50 years, global seafood consumption has increased, with the most noticeable changes taking place in the least developed and food insecure countries. However, the threat of climate change and its effects on ocean chemistry, have the potential to seriously jeopardize the health of marine organisms and their consumers alike. The purpose of […]
C10-T: Facial Movements of Native-Signing Children with and without ASD
This study is an investigation of how different populations–specifically individuals with autism spectrum disorder (ASD)–communicate and express themselves using American Sign Language (ASL). Previous research has found that hearing children with ASD produce more atypical, awkward, and slower facial expressions than typically developing (TD) children. Since sign language involves practice with facial expressions, we were […]
C29-P: Nutrient Deficiency Treatment on an Enrichment Culture from Lake Fryxell
Novel bacteria taken from the Antarctic lake, specifically from Lake Fryxell is tested under a nutrient deficient stress with the purpose of learning about the diversity of microbial communities. The goal of the research is to observe the community structure under nutrient deficient conditions and how these conditions affect the original enrichment culture. The growth […]
B14-T: Contributions of the Mesolimbic Dopamine Pathway in Reversal Learning
Cognitive flexibility, which can be measured with reversal learning, is the ability of an individual to alter their behavior in response to changing environmental conditions. Past studies have found that dopamine (DA) is released in the nucleus accumbens (NAc) during reversal learning (Radke et al., 2019, Klanker et al., 2017). The present study sought to […]
A50-P: When Less is Not More: A Phenomenographic Investigation of High School Teachers’ Storyboards
Bulk water is an essential component for dissolution-the process in which ionic compounds are broken down into constituent charged species. Water solvates ions, engages in hydrogen bonding, exerts electrostatic forces, and contributes to the effects of entropy and enthalpy. Despite bulk water’s importance, its submicroscopic presence is often omitted from high school instructors’ pedagogical practices. […]
B21-P: Complementarity of Endoplasmic Reticulum and Bacterial Molecular Chaperones
This project is in the area of biochemistry and addresses research into prevention of protein aggregation-based diseases such as Alzheimer’s. In cells, molecular chaperones assist with correcting protein folding to prevent diseases caused by misfolded protein aggregation. Cochaperones stimulate and enhance chaperone activity by facilitating client protein presentation and ATP hydrolysis. Heat shock proteins (Hsps) […]
