Integrated Density Functional Theory And Experimental Study Of Optical And Electronic Properties For Mos2/ (Metal=Au, Pt, Ni, Cu) And Mos2/Graphene/Metal Heterointerfaces, Shishir Timilsena, Sanju Gupta, Muhammad I. Bhatti, Nicholas Dimakis

School of Integrative Biological & Chemical Sciences Faculty Publications

We present computational simulations and experimental analyses of various heterointerfaces constructed from two-dimensional molybdenum disulfide (MoS2) and graphene on gold (Au), platinum (Pt), nickel (Ni), and copper (Cu) substrates. We combined density functional theory electronic structure, optical properties, and work function to elucidate heterostructure changes due to metal selection, corroborated with experimentally determined surface electronic properties. Here, we correlate shifts in the metal d-band center relative to the Fermi energy with the MoS2 bandgaps and bandgaps in the Dirac point region of the MoS2/graphene/Metal heterointerfaces. For the Ni heterointerfaces, the upshift of the metal d-band relative to the Fermi energy …

Molecular Mechanisms Of L-Type Calcium Channel Dysregulation In Heart Failure, Arbab Khalid, Abu-Bakr Ahmed, Randeep Gill, Taha Shaikh, Joshua Khorsandi, Ali Kia

Department of Internal Medicine Faculty Research

The L-type calcium channels (LTCCs) function as the main entry points that convert myocyte membrane depolarization into calcium transients, which drive every heartbeat. There is increasing evidence to show that maladaptive remodeling of these channels is the cause of heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). Recent experimental, translational, and clinical studies have improved our understanding of the roles LTCC expression, micro-domain trafficking, and post-translational control have in disrupting excitation–contraction coupling, provoking arrhythmias, and shaping phenotype specific hemodynamic compromise. We performed a systematic search of the PubMed and Google Scholar databases (2015–2025, …

Pvc Biodegradation Potential Of Native Fungal Strains From Mt. Hood National And Tillamook State Forests, Bristol Ozturgut

University Honors Theses

Polyvinyl chloride (PVC) is a toxic, degradation-resistant environmental waste product. Recent research has revealed fungal enzymatic activity capable of biodegrading plastics. As PVC infiltrates local environments, it becomes imperative to determine the adaptability of local fungi to PVC substrates. In this experiment, 100 local native fungal strains sampled from the Tillamook State and Mt. Hood National forests and one commercial strain of common oyster mushroom were investigated for their ability to colonize and digest PVC by direct isolation on 0.1% and 0.2% PVC-enriched limited growth media. Substrates for positive cultures were imaged using Fourier transform infrared spectroscopy to analyze potential …

At Home In Horror: Women And Body Horror, Brooklynn Kreps

University Honors Theses

While most discussion around the subgenre of body horror focuses on its birthplace of film, the richest iterations come from women writing body horror fiction to explain the experience of womanhood. As body horror focuses on fear of painful or absurd mishap with the body. Women experience pain or absurdity in their own bodies every day with processes like menstruation, pregnancy, puberty, and heightened chances of becoming a victim of sexual assault. Furthermore, women experience society's forceful shaming and fear about natural processes of the body and experiences such as anger and sexual desire. Using this idea as a framework, …

So Who Gets To Be Modern? Jadidism And Reform In Late Nineteenth And Early Twentieth Century Russia, Grant Douglas Linville

University Honors Theses

Jadidism was a sociocultural reformist project from the 1880s to 1920s developed by Muslim intellectuals in the Russian Empire and the Soviet Union. The Jadidist movement derives its name from the "new-method" (usul-al Jadid) schools that spread Jadid pedagogy, which revolved around the inclusion of secular topics and Western knowledge as well as instruction in local, Tatar, and Russian languages, in addition to the already present religious studies accompanied by Arabic and Persian taught in the Islamic educational institutions the maktab and madrasa (primary and higher education respectively). Over time Jadidism grew to encompass a host of societal …

Self-Representation In Manga: The Importance Of Gay & Lesbian Visibility In Japanese Society, Rylan Newsom

University Honors Theses

This thesis examines the evolving landscape of gay and lesbian self-representation in Japanese manga through a hermeneutic analysis of three key texts: My Lesbian Experience with Loneliness by Kabi Nagata, and My Brother's Husband and Our Colors by Gengoroh Tagame. It investigates how manga functions not only as a storytelling medium but as a sociocultural mirror, uniquely positioned to illuminate the often-invisible negotiations of identity, shame, and social position that queer individuals experience in Japan. Through the lens of Takie Lebra's concept of bun (role or place in society), this project explores the ways in which queer characters seek legitimacy, …

Characterization Of The Quaternary Active Twin Lakes Fault, Mount Hood, Oregon, Johnathan Peterson

University Honors Theses

The High Cascades chain of volcanoes results from Cascade Arc volcanism and is responsible for the generation of the highest topography in the state of Oregon. Surrounding Mt. Hood at the crest of the Cascade chain in northern Oregon is the Mt. Hood Fault Zone, an extensional fault zone of generally north-south trending normal faults that down-drop this high volcanic topography. The Twin Lakes Fault is located just south of Mt. Hood and is one of the southernmost faults in the Mt. Hood Fault Zone, previously mapped as approximately 12-13 km in length. This study provides the first in-depth characterization …

Is Anoxia Tolerance A Common Trait In Fish Cell Lines?, Lori Tran

University Honors Theses

Most vertebrates need a constant supply of oxygen to sustain life, with disruption to O₂ supply or delivery quickly leading to cell and tissue damage and death. Many aquatic species are able to withstand long periods without O₂ due to evolving to survive the regular periods of hypoxia and anoxia in their natural habitat. The Austrofundulus limnaeus, or the annual killifish, in particular have shown the highest anoxia tolerance in all vertebrates and is a promising model for developing effective treatments for anoxia-related damage, such as heart attacks and strokes. The A. limnaeus are not the only …

Beyond Capitalist Realism: Indigenous Worldviews As Critique And Alternative, Celine Jessup

University Honors Theses

This paper engages Mark Fisher's Capitalist Realism: Is There No Alternative? as a foundational critique of late capitalism's ideological dominance, and proposes Indigenous worldviews as both a critical lens and a generative alternative. Fisher defines capitalist realism as a pervasive structure that colonizes imagination, depoliticizes systemic crises, and renders other ways of living unthinkable. He illustrates how capitalism commodifies resistance, pathologizes dissent, and obscures accountability, particularly through institutions like the call center and discourses on mental health and climate change. In contrast, the paper turns to Indigenous political theories—drawing on thinkers such as Kim TallBear, Daniel Heath Justice, Ocean Ripeka …

The Correlation Of Trauma-Informed Classrooms Without Support Infrastructure And Teacher Burnout, Sunshine O'Connor

University Honors Theses

This thesis examines the impact of Trauma-Informed Care (TIC) implementation in classrooms on teacher burnout, specifically focusing on settings with insufficient support infrastructure. While TIC is recognized as beneficial for all students, not just students affected by trauma, a synthesis of scholarly literature highlights the significant challenges faced by educators when proper resources, training, and institutional backing are lacking. Existing research indicates that teachers implementing TIC in inadequately supported environments report higher levels of emotional exhaustion, depersonalization, and overall burnout. These challenges appear most acute for teachers in schools with limited professional development, insufficient mental health resources, and weak administrative …

Testing Their Limits: Impact And Intentions Of Standardized Testing In K-12 Schools, Grace O. Herd

University Honors Theses

The integration of High-Stakes standardized testing into U.S. public education to serve as an accountability system has been a disputed issue since the No Child Left Behind Act (NCLB) mandated these assessments nationwide in 2002. NCLB aimed to locate and identify schools failing to reach Adequate Yearly Progress (AYP) and trigger a chain of interventions based on student performance, as an effort to track measurable outcomes from federal education funding. While supporters view these standardized tests as quantifiable data for school effectiveness in academics, critics challenge the claim of validity.

This review integrates current psychological research in the area of …

Virtual Versus In-Person Rose Program (La Luz) As Universal Prevention For Perinatal Depression: Protocol For A Randomized Controlled Trial In A Safety Net Hospital, Daphne Y. Liu, Nicholas S. Perry, Catherine H. Demers, Jennifer S. Hyer, Anely Alamo, Paige Vuksanovich, Nandi Dube, Erin R. Flanagan, Robert J. Gallop, Galena K. Rhoades, Elysia Poggi Davis

Psychology: Faculty Scholarship

Perinatal depression disproportionally affects underserved communities, who need effective and accessible prevention programs. Reach Out, Stay strong, Essentials for new mothers (ROSE) has demonstrated effectiveness in preventing postpartum depression in underserved populations when delivered in person. This ongoing randomized controlled trial (RCT) tests the novel virtual implementation of ROSE as universal prevention in a Federally Qualified Health Center setting. We adopted the name, La Luz, for ROSE to be culturally relevant to our population. Pregnant individuals < 30 gestational weeks (target N = 900) are randomized to either the virtual or in-person La Luz program, which consists of four 90-min group sessions. Groups are offered in English and Spanish, based on participants' preference. Participants complete surveys at seven timepoints: before program, 28 gestational weeks, 35 gestational weeks, and 6-weeks, 3-months, 6-months, and 12-months postpartum. Primary outcomes are postpartum depression severity measured by the 20-item Symptom Checklist (SCL-20) and 10-item Center of Epidemiologic Studies Depression Scale (CESD-10). We will perform intent-to-treat analysis to test whether virtual La Luz is non-inferior to in-person La Luz. This study also evaluates implementation process and outcomes of both modalities of La Luz to inform the development of an implementation toolkit. This RCT contributes to our knowledge of perinatal depression prevention and addresses access barriers for underserved populations. If effectiveness of virtual La Luz is demonstrated, the new evidence for a scalable low-cost prevention can be used to reduce perinatal depression and offer accessible treatment options for people who face significant barriers to care.

Design And Evaluation Of An Innovative Biomimetic Coral Transport Container, John-Christopher L. Calulo, Wilfredo Y. Licuanan, Leah D. Madrazo, Dana Isabelle P. Villano, Angel Nicole B. Villanueva

Sinaya: A Philippine Journal for Senior High School Teachers and Students

Coral reefs are vulnerable to disruptive human activities such as pollution, overfishing, and coastal development—degrading water quality and reef structures. Active reef restoration entails temporarily relocating several corals to aquaculture facilities to achieve successful rehabilitation; however, current coral transport methods pose certain risks, such as stress-induced mortality, which can result from physical damage during transportation. Existing studies on coral transport have explored various techniques for collecting, shipping, and maintaining live coral specimens. The design consists of petal-shaped areas where the waves gather, akin to a coral reef’s grooves, separated by wedges—the spurs—that cause waves to divide. The different design modifications …

You're Such A Princess, Andree Sole

Dartmouth College Master’s Theses

You’re Such a Princess is a five-play anthology that reimagines well-known folk tales. By re-imagining four Brothers Grimm tales and one by Hans Christian Andersen, I follow a centuries-old tradition. As scholar Donald Haase explains, folk tales evolve with each retelling, allowing their ‘morals’ to shift over time. I have created encounters between real people (extending characters beyond Vladimir Propp’s Dramatis Personae) and revised the endings to challenge the audience. My Snow White character hews closer to the pejorative implications of calling someone a ‘princess’ in our society: entitled, arrogant, spoilt. Two of my storylines (Little Red Cap and The …

Late Holocene To Modern Dust Increases In Antarctic Ice Cores, Lillian D. Tipton

Dartmouth College Master’s Theses

Dust aerosols impact global climate by influencing direct and indirect radiative forcing, serving as cloud condensation nuclei, and supplying trace nutrients to the ocean that affect the marine biological pump. Antarctic ice core dust records show dust deposition changing in step with global climate over the past eight ice-age cycles. However, fewer studies have focused on Antarctic dust deposition during the late Holocene-to-modern period. Notably, 20^th-century increases in dust deposition have been observed in ice cores from James Ross Island (JRI) and Dronning Maud Land, with the JRI record hypothesized to reflect desertification and land-use changes in Patagonia. …

Devices Related To Electrical Fast-Transient Protection And Detection, Cameron D. Harjes

Electrical and Computer Engineering ETDs

Electrical energy from natural occurring phenomena, such as an indirect lightning strike, can electromagnetically couple with nearby electronics thereby generating unwanted electrical fast-transients (EFT) signals in the circuit. Highly energetic EFT can interfere with a circuit’s normal operation or even destroy some circuit components entirely. Mitigating EFT has been a subject of research for decades and led to the development of devices such as lightning surge arresters (LSAs). These devices are critical for the protection of the electrical power grid from lightning induced EFT, however electromagnetic pulses (EMP) and other high-power radio frequency (RF) sources can generate much higher frequency …

Hydropneumopericardium Due To Esophageal-Pericardial Fistula: A Rare Complication Of Esophageal Stenting, Svenja Schneider, Margaret Doyle, Suzanna Talento, Waqas Ullah, Gregary D. Marhefka

Division of Cardiology Faculty Papers

We present a case of a 53-year-old woman with a history of ulcerative esophagitis and esophageal stricture status post esophageal stenting that was complicated by stent migration. She presented with fatigue, melena, and dark output from her percutaneous endoscopic gastrostomy tube. An echocardiogram showed hydropneumopericardium with cardiac tamponade physiology requiring emergent pericardiocentesis. The aspirated fluid was brown and cloudy; pathology of the fluid showed meat and vegetable matter consistent with food. She ultimately required esophagectomy with esophagostomy. This case highlights the importance of early recognition of esophageal-pericardial fistulas, as delay in the management carries a high risk for morbidity and …
