  Religion and Juvenile Deviance

  Rachel Burton

  This research looks to analyze and identify a correlation or lack of correlation between religion and criminality. Past literature presents a variety of results that prevents any concrete determination of a correlation. Through a negative binomial regression, this research looks at data from interviews of juveniles ages 14 to 18 to see if a relationship exists between higher crime rates and the importance of spirituality in their lives. The results of this research contribute to a better understanding of spirituality on individual’s criminal behaviors and specifically adds a focus to the youth population.

  Renewable Natural Gas - Demonstrating the Potential of the World’s Biggest Battery

  Subathra Rajendran

  TITLE: Renewable Natural Gas - Demonstrating the Potential of the World’s Biggest BatteryI. ObjectivesThe proposed effort aims the development of commercial and technological models to demonstrate the feasibility of a closed loop renewable natural gas power production model. This process is also called Power-to-Gas (P2G).II. Method(s)Power-to-Gas represents the conversion of electrical power into a gaseous energy carrier such as methane. The overall proposed approach to P2G involves the conversion of renewable/excess electricity into natural gas using high temperature electrolysis, carbon capture in the form of CO2, and catalytic methanation. The electrolysis generates hydrogen (from water), which combined with the captured CO2 (i.e. from power plants’ flue gases) forms, under a catalytic environment, methane (methanation). In order to assess the feasibility of such an approach, the following steps will be carried out:•Identification of commercial-off-the-shelf (COTS) technologies for electrolysis/hydrogen production, carbon capture and methane production•Develop several integrated configurations of these technologies that are suitable for large-scale methane production (10 MW) and analyze their cost-benefit•Predict current and future costs associated with the proposed P2G systems III. SignificanceThe current geopolitical dynamics have more than ever highlighted the importance of energy independence. The existing US natural gas infrastructure has a capacity that would satisfy the domestic energy requirement for up to one year. However, it is only used at 30% of its capacity. Several countries, including the US, are racing to implement more renewable energy infrastructures. However, their dependence on natural events (sun exposure, wind intensity) often leads to peak energy productions where excess energy is lost. Thus, the ability to store such energy for later use would be of utmost importance. P2G offers a long-term and alternative solution to other energy storage technologies such as batteries or hydrogen storage. The methane produced from P2G can be stored directly in the existing infrastructure. Hence, an alternative to traditional batteries. Hydrogen storage has very strict requirements in terms of materials and safety, and the existing US natural gas infrastructure is not compatible for hydrogen storage. The proposed work will deliver several technological configurations and their associated costs for a large-scale P2G production. In addition, it will predict how improvements on existing technologies, in terms of costs and efficiencies, might affect P2G implementation costs in the future

  Resolving a gene network for a developmentally patterned and rapidly evolving fruit fly trait

  Corinne Stone, Rachel Stanojev, Emily Daniel

  Our research aims to further resolve a gene regulatory network (GRN) responsible forthe development of a male-specific (dimorphic) pattern of pigmentation on the abdomensegments of the fruit fly Drosophila (D.) melanogaster. The male A5 and A6 segments are blackin color from melanin pigment produced by the resident epidermal cells. These melanicsegments differ from the non-melanic A1-A4 segments, and the A5 and A6 segments offemales. Previous studies identified 30 regulatory genes whose functions are needed for thisdimorphic pigmentation, and found the cis-regulatory elements (CREs) that control theepidermis expression of four genes that encode pigment metabolism enzymes, and one CREthat controls expression of a key regulatory gene. Here we describe a plan to use RNA-interference to turn down the expression of these regulatory genes one-by-one, and determinewhat effects reduced expression has on the function of these five CREs. The results will revealconnections between regulators and their target genes that embody a pigmentation GRN.Abdomen pigmentation differs between fruit fly species, so success in characterizing this D.melanogaster GRN will bolster future studies on how this GRN evolved. Few animal GRNs havebeen characterized, and thus the breadth of regulatory genes and their CRE interactions remainunclear. While all traits have evolutionary histories, how they originate, become modified, andlost has not been characterized at the level of GRNs and CREs. However, fruit fly pigmentationpresents an ideal trait and species lineage to study GRNs, as its genetic tools are second tonone.

  Revealing the Dynamics of the Brain-Limb Axis During Limb Regeneration

  Ben Klocke, Jason Tornes, Kaitlyn Martin, Augustine Miller; external collaborators include Dr. Katia Del Rio-Tsonis at Miami University (Oxford, Ohio) and Dr. Mario Looso at the Max Planck Institute for Heart and Lung Research (Bad Nauheim, Germany).

  Complex tissue regeneration is an uncommon ability which can only be found in a small subset of vertebrates, with one of these being the amphibious axolotl, a salamander capable of regenerating its limbs following amputation. While the necessity of nerves in the process of limb regeneration has been well studied, the possible role of other components of the nervous system, such as the brain, is largely unknown. In the current study proteomics, gene expression and immunohistochemical approaches were employed to investigate changing protein expression patterns at various time-points throughout the process of limb regeneration. In the context of this presentation, we highlight intriguing neurobiological alterations that occur in the axolotl brain during limb regeneration, in an effort to shed light to the regulation of this fascinating physiological process.

  RFID based attendance system

  Kovidh Kumar Tatikonda

  The RFID attendance system project aims to create an efficient and accurate system for tracking attendance in educational institutions, offices, or any other organization. The system will use RFID technology to identify and record the attendance of individuals, eliminating the need for manual tracking and reducing errors.The system will consist of RFID tags, RFID readers, an Arduino microcontroller, and a database to store and manage attendance data. Each person will be assigned a unique RFID tag that they will carry with them. When the individual enters the premises or the classroom, the RFID reader will detect the tag, and the Arduino microcontroller will record the attendance in the database.The attendance data will be stored in a cloud-based database, which can be accessed by authorized personnel to view real-time attendance reports. The system will also send automated notifications to parents or supervisors in case of absence or tardiness.The project will also include an LCD screen for displaying attendance data, a buzzer for indicating successful attendance, and an LED for displaying system status. The system can be powered by either a battery or an AC adapter.Overall, the RFID attendance system project is a cost-effective and reliable solution for tracking attendance in any organization. It eliminates the need for manual tracking, reduces errors, and provides real-time attendance reports, making it easier for administrators and supervisors to manage attendance effectively.

  Right-Sizing Solar Systems for Low-Income Housing

  Rishabh Sanjaykumar Shukla, Phillip Clayton

  Tools for estimating the solar systems for a building often err in oversizing out of caution in their results. This is fine for people who can afford the upfront cost and can wait for the eventual payback. But this makes it difficult for people with lower income to afford a solar system for their home, and lower income families are often the ones who could most use a relief from high energy bills.Our goal is to create an analysis tool that estimates the right size of solar system needed to fulfil the energy needs of a building with the lowest payback period and the least amount of energy going back into the grid.Using data for houses in the Dayton area with average, low, and high energy usage, we have analyzed what the payback period, amount of the load is met, and how much power is going back to the grid for various sizes of solar and battery capacities in a system. We then shifted these data sets +/-4 hours to analyze different scenarios of when energy consumption may line up with solar system production.The results of this analysis have given us a good idea of how certain combinations of solar and battery capacity in a system can work in buildings of different amounts of energy consumption. We will be able to build on this research in the future, to look at what solar systems will be needed if all the energy requirements of a building are converted to electricity. We will also record the actual energy usage of low income homes in the Dayton area to compare to this analysis.

  Rising Interest Rates and Energy Price Trends in 2022

  Matthew Dahlke

  The macro environment in 2022 included a sustained effort by the US Federal Reserve to curb inflation through a major increase in the Federal Funds rate. In this study, I look at the growth rate trends in energy commodities (e.g. natural gas) and energy services (e.g. electricity) to see if their price trends are declining due to the Fed's policy of monetary tightening. I also compare the energy price growth rates to overall CPI growth rates to see if they trend together. I use year over year by month growth rates and rolling 3 month growth rates annualized to develop my trend analysis.

  The 2023 cohort of the University of Dayton River Stewards, the flagship program of the Rivers Institute, partnered with Dakota Center, a community partner located in West Dayton. The Rivers Institute, housed with other leadership development programs in the Fitz Center for Leadership in Community, uses a watershed model of community to promote service, learning, and leadership in Dayton and its neighboring communities. Capitalizing on an established relationship with the Dakota Center, the River Stewards began work towards revitalizing outdoor space at the Dakota Center, an under-utilized asset of the organization that could better serve both the afterschool and the senior programs there. The senior cohort organized volunteers from other cohorts in various garden days at the center and successfully wintered the garden, improved the raised beds, and prepared the garden for spring planting. In the off-season, the cohort developed a sustainability curriculum for the center’s afterschool program. These lesson plans drew upon the cohort’s interdisciplinary expertise, with a myriad of topics spanning from food sustainability to insect observation. As graduating seniors, the cohort intends for younger cohorts to continue nurturing this partnership; seniors compiled comprehensive lesson plans so future cohorts can continue the sustainability curriculum and garden days at the Dakota Center. The River Stewards hope that this project strengthens their partnership with the Dakota Center, that the curriculum enhances young people’s understanding and practice of sustainability, and that the garden days improve a space that inspires the joy of the outdoors in the greater Dayton community. The cohort thanks Mike Miller, Erin Wilson, Kristine Irby, Leslie King, and Kam Lee for their support and mentorship on this project.

  Robotic Additive Manufacturing

  Ajith Kumar Veeraboina

  Additive manufacturing (AM) is a technology that produces a physical part directlyfrom its corresponding digital 3D model design. AM technology has been widely used in manyfields for rapid prototyping. Technological advancements in AM have shifted its purpose tomanufacturing. However, when compared to traditional manufacturing, AM is a slow process.So, the fabrication process speed must be improved by developing new mechanisms and slicingalgorithms and a model can be printed faster without sacrificing the surface quality and itsmechanical properties. Moreover, the 3D part fabrication time is dependent on the CAD model’scomplexity, such as overhanging structures. Most of the commercial 3D printers are based on agantry system, so printing such complex models requires support structures. So, it takes moretime and material to print both the support and the actual part. Therefore, developing multi-directional tool-path algorithms can minimize fabrication time. However, such algorithms canbe implemented only with a higher degree of freedom (DOF) mechanism, like industrial roboticarms. In this report, we have discussed about printing process architecture with a one six DOFmanipulator and testing a novel tool-path planning to improve mechanical properties with smoothsurface quality. Tensile tests are performed as per the ASTM D638-20 standards.

  Role of M1BP, a transcriptional pausing factor in JNK-mediated cell death during eye development

  Hannah Darnell, Anuradha Chimata Venkatakrishnan

  During development, transcriptional regulation is a fundamental mechanism(s) to regulate differential gene expression. Recently, we have shown that M1BP, a transcriptional pausing factor and a functional homolog of ZKSCAN3, promotes cell survival in developing eyes by suppressing wingless (wg). We performed a forward genetic screen, to identify other targets of M1BP mediated transcriptional repression that may contribute to eye suppression phenotype. We identified members of Jun-amino-terminal-(NH2)-Kinase (JNK) signaling pathway as modifiers of the “no-eye” or “reduced-eye” phenotype of MIBPRNAi. We hypothesized that M1BP may promote cell survival in developing eyes by downregulating JNK signaling. Using the Gal4-UAS system, we modulated both JNK signaling components along with downregulation of M1BP function and assayed their role in cell survival during eye development. We found that downregulation of M1BP results in activation of JNK signaling which in turns activates both apoptosis as well as autophagy. Activation of JNK signaling enhances M1BPRNAi phenotype and downregulation of JNK signaling rescues the M1BPRNAi “no-eye” phenotype. Secondly, blocking cell death or autophagy alone genetically does not completely rescue M1BPRNAi phenotype of “no-eye”. Finally, downregulation of M1BP along with blocking both apoptosis and autophagy resulted in a significant rescue of the M1BPRNAi ”no-eye” phenotype. Here, we present the role and mechanism by which transcriptional pausing promote cell survival in developing eye.

  Role of ZFP36L1 in suppressing human coronavirus replication

  Andrew Villasenor, Tooba Shafeeque Ahmed Momin, Malabika Bhowmik

  ZFP36L1 is a CCCH-type zinc figure protein (ZFP) where zinc ions coordinate the protein structure in a tetrahedral geometry by binding to cystine-cystine or cysteine-histidine amino acids. ZFP36L1’s unique structure enables it to interact with a wide variety of molecules including RNA; thus, it could modulate several cellular processes including virus replication. Several CCCH-type ZFPs have shown their antiviral efficacy against various DNA and RNA viruses. However, the role of ZFP36L1 in the human coronavirus is little explored. We used human coronavirus (HCoV)-OC43 to determine the role of ZFP36L1 on its replication. We overexpressed and knockdown ZFP36L1 in HCT-8 cells individually using lentivirus transduction. Wild type, ZFP36L1 overexpressed, and ZFP36L1 knockdown cells were each infected with HCoV-OC43, and the virus titer in each cell line was measured over 96 hours post-infection (p.i.). Our results show that HCoV-OC43 replication was significantly reduced with ZFP36L1 overexpression while ZFP36L1 knockdown significantly enhanced virus replication. ZFP36L1 knockdown HCT-8 cells started producing infectious virus at 48 hours p.i. which was an earlier timepoint as compared to wild-type and ZFP36L1 overexpressed cells. Wild-type and ZFP36L1 overexpressed HCT-8 cells started producing infectious virus at 72 hours p.i. Overall, the current study showed that overexpression of ZFP36L1 suppressed human coronavirus (OC43) production

  Runoff to the Mangroves: Agricultural Runoff over Time in Volusia County, Florida

  Lauren Corrigan

  Mangrove habitats are coastal wetlands that make up less than 2% of marine environments. In the United States, mangrove habitats are located along the coast of Florida. These mangrove habitats are important because they protect the coast from erosion, are habitats to many organisms, and serve as a filter to rid carbon dioxide. It is important to monitor anthropogenic disturbances since mangroves play a crucial role in the ecosystem. This study will display geographic data of agricultural runoff over time. It will show total nitrogen and phosphorus inputted into the environment over about a ten year time frame in Volusia County, Florida. It will help show how agricultural runoff can cause possible transgenerational effects in organisms that live in these areas by showing areas of high runoff overtime.

  Saving Light

  Trevor Benning

  From the moment you walk in a room and turn on the light, how much energy is used? To solve this, an Arduino microcontroller will be used to automatically detect when a door is opened and track how much energy is being consumed from lighting the room. Utilizing Arduino and Node Red, the data that tracks the energy consumption will be sent to a virtualization platform where the data will be analyzed and displayed. This data will help limit the amount of wasted energy by only turning the light on when someone enters the room and turns the light off when they leave.

  Scalable purification of High Purity Recombinant Lanthanide Ion Selective Protein from Methylorubrum extorquens and metal binding affinities

  Courtney Henthorn

  I will be discussing a novel purification method for isolating the lanthanide-sequestering protein, Lanmodulin, from an E.coli expression process, in addition to discussing comparative metal binding affinities of Lanmodulin to Europium(III) and Iron(III). This research topic is of major interest due to the unfulfilled demand for a national, sustainable supply of rare earth elements (REEs), for applications such as permanent magnets, energy storage devices, biomining, and metal waste valorization. My findings include a reproducible and scalable purification method for the isolation of His6-tagged LanM, its resulting activity compared to a LanM purified using a published method, and confirmation that heat treatment does not hinder the metal binding properties of LanM nor reduce the yield of the LanM.

  Screen Printing Liquid Metal Ink for Wearable Technology Applications

  Elizabeth Shafer

  Liquid metal inks are printed onto a variety of substrates to create stretchable, flexible, wearable technology. Methods like blade coating and drop coating have been consistently effective to print liquid metal inks through masks onto flexible, stretchable substrates. These methods require a significant amount of time and manual labor to create each individual print. While effective, there is a need for a more efficient method to make this technology more accessible. We demonstrated that screen printing is an effective and efficient process to print liquid metal ink. It is simple, repeatable, and accessible. Anyone with the resources could learn how to print liquid metal ink. Screen printing also makes it possible to cleanly print smaller features than blade coating or drop coating. Intricate, precise masks can be designed and created.

  Secondary “Success”-ion: Healing Post-Agricultural Soils Through Prairie Plantings

  Valerie Thurston

  Ecological restoration in landscapes heavily impacted by industrial agriculture is a pressing scientific concern that will require the development of techniques that facilitate the establishment of biodiverse habitats in post-agricultural fields. Ecological invasion is a significant concern in old-fields of the American Midwest and early establishment of problematic trees such as Pyrus calleryana may alter the course of secondary succession. Some evidence suggests that more biodiverse habitats may inhibit ecological invasion in some settings (i.e. the diversity-resilience hypothesis), but little is known about how prairie diversity may influence woody establishment in Midwestern old-fields. Working with our community partners at the Five Rivers Metroparks (Dayton, Ohio), we have established a fully replicated long-term restoration experiment on a 30-acre former agricultural field. The long-term management goal for this abandoned farmland is to establish a prairie community that transitions to mature oak forests. The experimental design includes four prairie seed mix treatments each replicated 5 times in 50 × 50 m plots and applied in spring of 2020: (1) high diversity with high legume content; (2) high diversity with low legume content; (3) low diversity with high legume content; (4) low diversity with low legume content. Each of the plots was then subdivided into four subplots and each of these received one of four soil amendment treatments: (i) leaf mulch; (ii) whole soil inoculation; (iii) whole soil + leaf mulch and (iv) control. Vegetation was assessed systematically using two transects to establish six 1m² quadrat within each subplot. Initial observations suggest that higher diversity seed mixes establish more diverse plant communities, and those diverse communities garner more niche space in the plant community. These results offer preliminary support for the diversity – resilience hypothesis given that a reduction in open space in the community should make it more difficult for invasive species to establish. Ongoing work seeks to discern the presence of exotic and invasive species throughout the restoration experiment and relate the abundance of invasive species to biodiversity of the established prairie community.

  Seizure Identification and Prediction Using DeepLearning

  Abigayle Hahn

  Epilepsy is often characterized by uncontrolled electrical activity in the brain that manifests as seizures. Behavior has been used to identify seizure activity in humans for a long time and it is the most commonly used way to identify human patients with epilepsy. However, most of the behavioral scales that are used to identify seizures are observer biased and do not capture the dynamics of seizure activity. Importantly, we don’t have any reliable methods to predict the onset and severity of seizures. Recent advances in machine learning and artificial intelligence offer us new avenues to automate the identification of seizures from video datasets. We hypothesize that seizure activity in a preclinical mouse model of epilepsy can be reliably captured using a DeepLearning approach. Using a large dataset of clinically-relevant seizure activity in mice, we have annotated key anatomical features across different epileptic stages. We used the DeepLabCut toolbox to train a model to identify 28 key body components across our entire dataset. Our model is able to capture kinematic data in novel seizure videos with a high degree of accuracy. We plan to further refine the accuracy of our model using an active learning approach and by increasing the amount of training data. Using the kinematic data from our video data sets, we plan to identify and define seizure states from a purely data-driven standpoint. Our ultimate aim is to translate our approach to a clinical setting in order to prevent Sudden Unexpected Death in Epilepsy (SUDEP).
