|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.||Denise Costanzo||288||Alumni Hall, HUB-Robeson Center|
|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|
|Creation of a pollen database for forensic identification purposes||Nycol Cotto Flores||

|DEFINING STAGE-SPECIFIC AND CONSTITUTIVE PROMOTERS IN PLASMODIUM YOELII||Logan E Finger||
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.

|Designing and Testing a Shutter System to Simulate Unsteady Flow Conditions in a Wind Tunnel||Colin Vollmer||I'm designing a better system to create unsteady flow within a wind tunnel. Gaining a better understanding of how unsteady flow functions and influences heat transfer will allow for great improvements to turbine designs. I started by analyzing an existing prototype to improve on its design. After designing in SolidWorks, I used additive and traditional manufacturing to assemble a shutter system for other researchers to use that creates controllable unsteady flow.||Stephen Lynch||224||Alumni Hall, HUB-Robeson Center|
|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.||Claude dePamphilis||176||Alumni Hall, HUB-Robeson Center|
|Detection of Neutrinos with CRES||Jacob Miller||Neutrinos were first detected ~60 years ago, and yet remain one of nature's most elusive particles, with their fundamental properties still not quite resolved, and their mass still unknown. The Project 8 experiment seeks to determine the absolute neutrino mass via the precise measurement of the electron energy in beta decays, using a novel technique called Cyclotron Radiation Emission Spectroscopy (CRES), which allows single electron detection through the measurement of radiation emitted by magnetically-trapped electrons.||Luiz de Viveiros||345||Heritage Hall, HUB-Robeson Center|
|DETERMINING THE EFFICIENCY OF EMBOLI DETECTION WITH DOPPLER ULTRASONOGRAPHY||Cara Pearson||
In the United States, Pulmonary Embolism (PE) accounts for 100,000-200,000 deaths annually. Early identification and treatment of the presence of emboli in the systemic vasculature could decrease mortality. Detection of emboli with Doppler ultrasonography is a method in which efficacy is dependent upon embolus size, flow rate, and user error. The objective of this study is to quantify the efficiency of Doppler ultrasound at detecting emboli of various sizes over a range of physiological conditions.

|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.||Sophia McClennen||109||Alumni Hall, HUB-Robeson Center|
|Effect of Bt Cotton on Indian Farmers||Lacey Walker et al||
Cotton production in India has been facing difficulties as failures arose with Bt cotton. Bt cotton failure leaves India facing problems such as lower crop yields, costlier seeds, harmful environmental impacts as well as alarmingly high suicide rates. India also faces challenges with excessive use of pesticides that include health hazards and environmental pollution. Bt cotton has forced farmers to consider reverting back to traditional methods of production due to economic, sociocultural, and environmental issues.

|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.||Daudi Waryoba||121||Alumni Hall, HUB-Robeson Center|
|Effect of Inhaled Corticosteroids on Body Weight and Lung Inflammation in Mouse Model of Chronic Childhood Asthma||Allison Ching||Allergic asthma is a common chronic condition often treated with inhaled corticosteroids (ICS). Allergic asthma was induced in mice using intranasal administrations of house dust mite (HDM) three times a week during development. Fluticasone (ICS) was administered intranasally concurrently with HDM at three doses. Results showed that low and moderate doses decreased lung inflammation in mice treated with HDM. ICS also decreased body weight, mimicking a side effect seen in human children.||Sonia Cavigelli||151||Alumni Hall, HUB-Robeson Center|
|Effect of PdQV on PdPV in Pseudogymnoascus destructans||Sherveen Karbasiafshar||White nose syndrome is responsible for the death of over 5 million bats and is caused by the fungus Pseudogymnoascus destructans (Pd). Pd is infected with a novel partitivirus, Pseudogymnoascus destructans partitivirus (PdPV). Pd isolates from Pennsylvania often have an additional virus, Pseudogymnoascus destructans quintipartite virus (PdQV). To test the effect of PdQV on PdPV, Pd strains with and without PdQV were grown in culture and the levels of PdPV RNA were compared using q-RTPCR.||Marilyn Roossinck||242||Alumni Hall, HUB-Robeson Center|
|Effect of Prenatal Vitamin D Supplementation on Placental Terminal Villi in Bangladesh||Casey M Carr||
This study attempts to understand the effect of vitamin D on placental angiogenesis. Placental tissue samples (n=80) were obtained after delivery from a randomized, dose-ranging, placebo-controlled trial of maternal vitamin D supplementation with four groups. Angiogenic outcomes, terminal villi count, density, area, and VEGF expression, were quantified using ImageJ. Analysis shows vitamin D supplementation compared to placebo did not have a significant effect on any of the angiogenic outcomes.

|Effect of Student Living Environments on Physical Activity Levels||Lucas Elliott||This study analyzed data from Penn State students to determine their activity levels relative to living environment. Comparing students living more than 15 minutes from campus with better amenities for physical activity and those living less than 15 minutes from campus; we discovered trends in physical activity among the populations. Although students living farther from campus had better amenities, they were less active. Universities should encourage the use of active transport instead of sedentary resources.||Melissa Bopp||246||Alumni Hall, HUB-Robeson Center|
|Effects of Anthropogenic Noise on Nesting Time and Fledging Success of Songbirds||Hunter Kauffman||
The effects of anthropogenic noise from shale gas compressors on the nesting time and fledging success of Eastern Bluebirds and Tree Swallow was studied throughout one summer at the Rock Springs Research Facilities in Centre County, PA by tracking 40 constructed pairs of nest boxes with either a noise treatment and a silent control. We looked at the time of nesting and fledging success of birds at both experimental and control pairs of boxes.

|Effects of Butyrate on Lamb Blood Results||Morgan Hultman||Objectives were to determine effects of butyrate concentrations in lambs fed 85% concentrate. 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.||Roberto Iglesias-Prieto||324||Heritage Hall, HUB-Robeson Center|
|Effects of elevated beat rate on the hemodynamics of the Penn State pediatric ventricular assist device||Brady Houtz||
Penn State has developed a pulsatile pediatric ventricular assist device (PVAD) to reduce the mechanical circulatory load for children on the heart transplant waiting list. The average pediatric heart rate ranges from 100-180 bpm. The hemodynamics of the PVAD with an elevated beat rate of 125 bpm was quantified using particle image velocimetry. The higher beat rate created a stronger inlet jet and a more sustained recirculation, suggesting a reduced susceptibility to clotting.
|Keefe Manning||347||Heritage Hall, HUB-Robeson Center|
|Effects of Inhaled Corticosteriods on Anxiety-Like Physiology and Behavior in Mouse Model||Samantha Studer||Inflammation associated with allergic asthma is often controlled with inhaled corticosteroids (ICS). Here, we used an allergic asthma mouse model to study ICS's effects on anxiety-like physiology and behavior. We measured corticosterone levels in serum and feces, and we measured anxiety-like behavior on the elevated plus maze in mice treated chronically with house dust mite allergen and ICS. Our results showed that there was a negative relationship between the doses of ICS and anxiety-like behavior.||Sonia Cavigelli||268||Alumni Hall, HUB-Robeson Center|

This study explores possible mechanisms creating long-term change of forest soil nutrients, namely mycorrhizae types and root thickness, using 6 tree species from a common garden in central Pennsylvania. Analysis showed significant variation between species in soil nutrient contents, and soil carbon, nitrate, ammonium, and pH of arbuscular mycorrhizal species were significant higher than ectomycorrhizal species.||David Eissenstat||150||Alumni Hall, HUB-Robeson Center|
|Elucidation of Novel Delayed Hatching Phenotype Observed in Caenorhabditis elegans||Teniola Idowu||C. elegans containing a knock-out mutation in the nmrk-1 gene do not synthesize an enzyme known as nicotinamide riboside kinase which is involved in the synthesis of NAD+. Preliminary results suggest that a combination of this genetic mutation and an environmental stressor result in a novel delayed hatching phenotype exhibited in eggs laid by nmrk-1 mutants. Our results provide more details about possible factors that may affect the strength of this observed phenotype.||Wendy Hanna-Rose||378||Heritage Hall, HUB-Robeson Center|
|Engineering Teams: Understanding the Process and the People behind the Products||Krina Patel||Working in teams is often difficult for many engineers, because the teams are impacted by an engineer's personality, behavior, and experience. Alongside these influences, the design process and the team interactions also impact the results of team projects in both industry and academic settings. The research study analyzes team interactions and behavior patterns, along with individual team member characteristics, to identify factors that influence the relative success or failure of each team's design process.||Kathryn Jablokow||191||Alumni Hall, HUB-Robeson Center|
