Competition between two Type VI positive strains of V. fischeri Anjali Mcneil The Type VI secretion system (T6SS) is a contact-dependent killing mechanism employed by many bacteria, including V. cholerae, P. aeruginosa, and several strains of V. fischeri, in competition for a niche. While interactions between T6SS+ and T6SS- strains are clearly defined and well studied, my project looks into interactions between two different strains that both have T6SS. This holds applications in studying competition mechanisms in larger microbiomes and in pathogenesis. Timothy Miyashiro 270 Alumni Hall, HUB-Robeson Center

Connecting the Growing Nonreligious Population to Their Religious Past through Architecture Kaila Hanln Christianity, among other religions, used to be a way of life rather than a belief. Yet, today, people are increasingly identifying with the "none" category when asked their religion. This can create a disconnect between this nonreligious population and their religious past. Modern religious architecture, starting with the Sagrada Familia, using a modernization and abstraction of religious themes and traditions modern religious architecture, helps to reconnect these people with their religious roots.

Correlating Platelet Adhesion and Surface Roughness in the Penn State Pediatric Ventricular Assist Device Cecilia Richardsen The Penn State pediatric ventricular assist device (PVAD) was designed as a bridge-to-transplant device for children on the heart transplant waiting list, but thrombus formation on the polyurethane urea blood sac remains an issue. After PVAD ovine studies, blood sacs were evaluated using immunofluorescence and confocal microscopy, environmental scanning electron microscopy (ESEM), and optical profilometry (OP). These data were correlated, demonstrating that areas of higher surface roughness could facilitate deposition of platelets and fibrin. Keefe Manning 316 Heritage Hall, HUB-Robeson Center
Costa Rica: Preventative vs. Reactive Medicine Aminah A Henderson

Costa Rica manages to spend less on healthcare then the United States, and yet manages to have better outcomes. So how do they accomplish this? What is being practiced in Costa Rica that makes their healthcare system so effective? Could it be due to a combination of, universal healthcare, cultural practices, work life balance, and diet? My research will look into these aspects as preventative measures and compare it to the United States.

Creating a dynamic model of the relationship between the input to a cruise controller and the ultimate vehicle velocity as a function of time. Nikita Arbuzov Today, engineers are struggling to create an efficient Adaptive Cruise Controller that can adjust speed trajectory of the vehicle depending on traffic lights information and nearby vehicles' behavior. In order for such cruise controller to change the vehicle's velocity accurately, we need to take into account the delay in implementing its commands. So, our project focuses on identifying this delay to pre-compensate it and further improve the efficiency of Adaptive Cruise Control Systems. Hosam Fathy 197 Alumni Hall, HUB-Robeson Center

Genetically-attenuated malaria parasites lacking essential genes are used as potent malaria vaccine candidates. CRISPR/Cas9-based gene editing is now a preferred method to create these parasites. However, these parasites must still be viable when administered as a vaccine, but completely arrested in the recipient. Therefore, precise, temporal expression of Cas9 is critical. To accomplish this, we have used a GFP reporter system to characterize the expression patterns of Plasmodium yoelii stage-specific promoters for expression of Cas9.

Detecting mobile DNA movement between host and parasitic plant, a potential mechanism of HGT Itsuhiro Ko Recently, several published studies have presented evidence of substantial horizontal gene transfer (HGT) events in parasitic plants. Interestingly, the "stolen" genes from the host have been incorporated into the parasitic plants' genomes. In this research, I'm seeking to detect genomic DNA uptake in Cuscuta from its host plant Arabidopsis, by nested polymerase chain reation (PCR), giving direct evidence of DNA transfer that has been hypothesized to facilitate HGT events.

Determining the Role of HMGA2 in Stress Erythropoiesis Krista Grennan Stress erythropoiesis is a process that the body utilizes to maintain homeostasis under stress conditions caused by anemia. Fetal hematopoiesis utilizes the Lin28b-let-7-Hmga2 axis to produce erythrocytes in a way that is similar to stress erythropoiesis. I hypothesized that the HMGA2 gene is upregulated during stress erythropoiesis as part of the Lin28b-let-7-Hmga2 axis in order to maintain homeostatic concentrations of oxygen in systemic tissue. HMGA2 targeted gene therapy may be the key to treating anemia. Robert Paulson 292 Alumni Hall, HUB-Robeson Center
Developing an alternative approach to RNA-Seq Julia Frances Cipparulo

Sequencing messenger RNA provides a readout of gene expression, which is misregulated in many diseases. However, standard RNA-Seq protocols have many steps that require trained hands to perform. We are attempting to develop a simplified approach to study gene expression that uses a provided probe library and an overnight hybridization step with isolated mRNA. By streamlining sample preparation, we hope this method will be an easier, cost-effective alternative to RNA-Seq.

Dynamics Associated with Bacteriocin Resistance in Pseudomonas syringae Andrew May Pseudomonas syringae pv. actinidiae causes Bacterial Canker of Kiwifruit. A competing Pseudomonas strain produces two toxins, with the second only active after resistance to the first develops. Resistant strains were sequenced to determine the second toxin's target, identifying four genes as candidates. Growth assays of these mutants determined that 2 of the 12 had slower growth rates. Understanding this system could lead to better response to outbreaks and development of biological controls in the future. Kevin Hockett 236 Alumni Hall, HUB-Robeson Center
ECONOMIC MARGINALIZATION ON MIGRANTS IN HOST COUNTRIES: AN INTERNATIONAL COMPARATIVE POLICY ANALYSIS Zachary Adams Refugees from hotspot countries of internal conflicts have re-assimilated themselves mainly into the European Union, the U.S., and Canada, as host countries for asylum and economic opportunities. However, many refugees have become economically marginalized via host country resettlement programs regarding the amount of assistance that is required for them to start a new life. What has manifested now is intense economic marginalization in these host countries through the lack of provisions in country-specific resettlement programs.

Effect of Chronic Stress on Somatostatin-Positive GABAergic Interneurons Shreya Bhatt Stress increases risk of developing Major Depressive Disorder. The brains of mice subjected to six weeks of Unpredictable Chronic Mild Stress (UCMS) show a reduced density of somatostatin immuno-positive cells. We are comparing the density of genetically labeled somatostatin cells and the density of somatostatin immuno-positive cells between UCMS mice and UCMS mice that underwent six weeks of recovery. We predict that the density of somatostatin immuno-positive cells returns to baseline after recovery from stress. Bernhard Luscher 259 Alumni Hall, HUB-Robeson Center
Effect of Hybrid Post-Sinter Treatment on Sinter Hardened (SH) Structural Parts from PM Steels Andrew Serafini Copper Infiltration (CI) with sinter hardened parts is utilized to ensure sufficient mechanical properties. However, CI usage results in cost increase and dimensional inconsistency. This study regards using an inorganic sealant (IS) by vacuum impregnation in place of, or along with, CI. The results show the effect on different mechanical properties and how this process can increase or match the use of just CI along with being a more cost effective method.

Treatments fed were: no butyrate, 1% butyrate, and 2% butyrate. Subjects were evaluated based on blood total protein, BHBA, and glucose. There were no interactions for blood parameters nor any treatment effects. BHBA decreased on d28 and d56 compared to d0. Glucose was greatest on d56 and least on d28; d0 was intermediate and not different from d56 or d28. Tara Felix 296 Alumni Hall, HUB-Robeson Center
Effects of butyrate on lamb growth and alleviating acidosis Morgan Brumbaugh The effects of increasing butyrate concentrations in lambs fed 85% concentrate were determined. Treatments: no butyrate (CONT), 1% butyrate (BUT1), and 2% butyrate (BUT2). Fecal scores, body weight and feed intake were recorded by pen. There were no treatment by day interactions (P= 0.9363); however, lambs fed BUT1 had the lowest fecal scores (P= 0.0144) and fecal score differed by day (P< 0. 01). Improved fecal scores corresponded to enhanced lamb performance and ameliorated acidosis. Tara Felix 298 Heritage Hall, HUB-Robeson Center
Effects of Coral Skeleton Multiple Light Scattering on the Light Absorption Efficiency of Coral Symbionts (Symbiodiniaceae) Theresa Hong The coral skeleton and its optical properties are suspected to have a role in coral symbiont efficiency to collect light. White skeletons allow for multiple scattering of light, increasing the light field of the symbionts. In excess light, the efficiency becomes too high, resulting in dinoflagellate photosynthetic damage and sometimes, death. It is hypothesized a decrease in multiple scattering will reduce the light field within the coral tissue and decrease the symbiont light absorption efficiency.
