Study The Effect Of Climate Change On Barley Crop (Hordeum Vulgare L.) And Improving Its Productivity Through Municipal Treated Wastewater Utilization, Wasef A. Alzayadneh

Thesis/ Dissertation Defenses

Climate change presents a complex risk to crop productivity, with elevated temperatures, rising CO2 and UV-B enhancement profoundly impacting growth. Although the effects of individual stressors are well-documented, limited information is available regarding the combined effects of variables such as elevated CO₂ (eCO2), UV-B radiation, and elevated temperature (eT). This knowledge gap is especially critical for major cereal crops such as barley (Hordeum vulgare L.), which ranks fourth in global production and serves as a valuable source of forage for livestock. However, traditional forage production is unsustainable in arid regions, where water shortage and extreme weather conditions are present, as …

How Journal Editors Are Addressing Challenges With No-Fee Open Access, Colleen Lyon, Christopher Hollister

All Things Open

No-fee or “diamond” open access embodies the principles of the UNESCO Recommendation on Open Science, particularly openness, inclusivity, and collaboration. This model of publishing strengthens equitable access to knowledge, promotes multilingualism, and democratizes science.

Unique among open access models, no-fee open access eliminates both APCs and subscription fees, making it completely free for both authors and readers. This model is often funded by academic institutions, governments, or non-profit organizations, focusing on equity, inclusivity, and accessibility.

To investigate the efficacy of this model, the presenters administered a survey of North American no-fee journal editors to explore the challenges of managing no-fee …

Studying The Role Of Combitional Flavonoids Against Toxicity Of Chemothrapeutic Drugs In Human Fibroblast Cells, Hussain Al Zouabi

Thesis/ Dissertation Defenses

Chemotherapy remains the primary treatment strategy for cancers; however, its clinical efficacy is often limited by severe toxic effects resulting in normal cells. The study investigated the protective potential of the flavonoids epigallocatechin-3-O-gallate (EGCG) and quercetin, used in combination, against chemotherapy-induced toxicity in human fibroblast F-180 cells. Cells were exposed to three commonly used chemotherapeutic agents, doxorubicin, cisplatin, and etoposide, in the presence or absence of EGCG and quercetin at concentrations of 25 and 50 μM. cells viability was assessed using the MTT assay, while oxidative stress and antioxidant capacity were evaluated by intracellular reactive oxygen species (ROS) and total …

Greenaissance? Zero-Embargo Funder Mandates And Green Open Access, Josh Cromwell

All Things Open

Recently, several funder-driven Open Access mandates, such as Plan S in Europe or the NIH Public Access Policy in the US, have indicated a desire to shift away from allocating funds for article processing charges (APCs) and have instead called for significantly reducing or eliminating embargo periods on accepted manuscripts (AMs) to make them a viable pathway to compliance for researchers.

This talk will address how these policies can significantly revitalize Green Open Access and open repositories, and will discuss strategies for researchers and librarians to use these new policy changes as an opportunity to share their research openly without …

New Directions In Gear Up Stem Camps: How Activity Design Shapes Socio-Emotional And Stem Outcomes, Lilly Rogers

ATU Scholars Symposium

This mixed-methods study examined the impact of GEAR UP week-long middle-school STEM summer camp on students’ socio-emotional learning (SEL) and STEM engagement. Using pre- and post-intervention surveys (N = 45), an exploratory factor analysis identified two underlying competency dimensions: Socio-Emotional Skills and STEM Engagement & Spatial Skills.

Computational Approaches To Laser Alignment And Phase Correction, Joseph E. Temple

ATU Scholars Symposium

The goal of our work is to automate the tedious and delicate process of optical alignment (rotating mirrors, shifting lenses by millimeters, and iterating endlessly) in the context of generating vortex beams from a Gaussian laser beam. We create vortex beams by illuminating a digital hologram displayed on a spatial light modulator (SLM). Two main issues arise: misalignment and phase imperfections in the input beam. If the beam does not pass directly through the center of the SLM, or if it deviates from an ideal Gaussian profile, the resulting vortex beam becomes distorted.

Last semester, we developed two methods to …

Interacting Dark Energy Models And The Cosmic Coincidence Problem, Gunner W. Hodges

ATU Scholars Symposium

Cosmological models are a tool used to understand the mysterious nature of dark energy and dark matter by predicting how these dark sector components have shaped the expansion of the universe. The cosmic coincidence problem stems from the present day densities of dark energy and matter sharing very similar magnitudes when previously we expect a much larger difference in orders of magnitude. The current best-fit model, ΛCDM , assumes dark energy is non-interacting; however, assuming that dark energy instead does interact could serve to alleviate this cosmic tension. We define an interaction where we relate the density of dark energy …

Automatic Three Phase Balancing In Utility Applications, Ryan Morris

ATU Scholars Symposium

Balancing three-phase power has become more important as modern loads like EVs and large agricultural fans create fast and uneven changes in distribution systems. Manual balancing is slow, inconsistent, and often only done during certain “seasons,” which leaves long periods of imbalance. This paper reviews existing automatic methods such as the Fast-Switching Relay method, the Practical Balancing Algorithm, and the Phase-EQ system and highlights their benefits and limitations. Based on this analysis, a new method called the Predicted Practical Balancing Algorithm (PPBA) is proposed. The PPBA combines the stability of threshold-based switching with historical data to predict when imbalances are …
