Synergistic Photodetectors Based On Sno2/Si With Cnts Via Vacuum Thermal Evaporation, Sozan A. Hassan, Walla M. Mohammd, Mohanad Q. Kareem, Kawkab D. Salim

Baghdad Science Journal

This study presents a precision-engineered carbon nanotube (CNT)-doped SnO₂/Si heterojunction photodetector, wherein interfacial physics governs performance beyond individual material capabilities. Stepwise CNT loadings (0, 0.03, and 0.07 wt.%) were deposited by vacuum thermal evaporation to systematically reconstruct the crystallographic, morphological and band-alignment landscape. A-sure X-ray diffraction demonstrates that the rutile phase remains, and atomic force microscopy and scanning electron microscopy confirm grain passivation at the nanoscale. High sub-bandgap light sensitivity can be achieved, benefiting from the built-in field-assisted carrier separation at the SnO₂/Si interface, whereby the redshifted absorption edge is indicative of intentional bandgap engineering.

Determining The Feasibility Of A Habituation Assessment In Managed Red Wolves, Emily C. Lynch, Joseph W. Hinton, Jennifer B. Nagashima, Curtis Malott, Natalie J. Johnson, Emily Haering, Robin Petersen, Allison Johnson, Julie K. Young

Wildland Resources Faculty Publications

For species extirpated from the wild, ex situ breeding programs are essential for providing the individuals necessary for re-establishing wild populations through reintroductions. However, repeated exposure to humans under managed care may reduce wariness and alter behavioral responses in ways that are maladaptive after release. Although some pre-release behaviors reflect natural responses essential for survival and reproduction, others may result from habituation to humans and increase the risk of conflict, recapture, or mortality following translocation. These risks underscore the need for behavioral assessments to help identify appropriate candidates for release. However, because the assessments themselves require some exposure to humans, …

Past The Watchful Dragons: How C. S. Lewis’S Fiction Humanizes The Analytical Framework Of The Problem Of Pain, Charlotte L. Hambrick

Masters Theses

C. S. Lewis was one of the 20th century’s greatest Christian apologists. Writing across multiple genres—from academic literary criticism to lay sermons, and from philosophical and theological analysis to several kinds of fiction—his impact on Christian thought remains profound. This thesis analyzes Lewis’s approach to the intellectual problem of evil in The Problem of Pain and demonstrates how he makes those starkly cold, prickly concepts more warm, human, and relatable in several of his works of fiction. It will first consider Lewis’s personal history with death, abuse, war, and grief, showing how his lived experiences with pain shaped his thinking …

Co-Dominion: The Changing Nature Of The Adamic Covenant In An Age Of Artificial Intelligence, Corey Hastings

Masters Theses

Theologians and religious bodies attest to the rising influence of artificial intelligence (AI) in governments, the economy, and the lives of the people of God. Through the covenant with Adam, God gave humans the blessing of dominion and capabilities unique to creation to till the earth. Today, humans retain the image of God but AI increasingly displaces human functions with coordinated agency. Using Hebrew language exegesis of passages from Genesis, Exodus, and Leviticus, this study compares capabilities gifted to humans with the scope of current and near future AI models.

Sovereign Borders: John’S Deuteronomic Framework For Israel And The Nations In The Apokalypsis, Kevin W. Mullen

Doctoral Dissertations and Projects

This dissertation concludes that John’s imagery of Israel and the nations in the Apokalypsis is distinctly shaped by his interpretation and incorporation of Deuteronomic theology. It employs a canonical and intertextual approach to inductively argue that Deuteronomy presents three pillars, or roles, for biblical nationhood: (1) objects of and instruments for divine judgment, (2) custodians to restrain evil, and (3) revelations of God’s sovereignty. These three Deuteronomic pillars establish the foundation for biblical nationhood and are expressed by John throughout his Apokalypsis. Moreover, this dissertation concludes that John’s imagery for the nations is due to his reliance upon the Deuteronomic …

Digital Presence In Live Hybrid Performance, Luke Cargill

Dartmouth College Master’s Theses

This thesis examines how digital presence, the sense that a digital performer is socially and performatively "there," is designed and tested in live hybrid performance. Drawing on four practice-based projects (Vicarious, Voltage, Vicarious: Encore Edition, and SUPER BLOOM), the first phase identifies a recurring but empirically untested claim: that digital presence depends on interactivity and co-presence with live performers, though these factors were always entangled in practice.

The second phase tests this claim directly. A new mini-performance, featuring the first fully AI-driven digital character in this line of work, was produced for controlled comparison. Using a 3 (intro type: AI-driven, …

Mobilizing The Church For Whole-Person Transformation In Addiction And Mental Health Recovery, Jacqueline A. Gillespie

Doctoral Dissertations and Projects

Individuals experiencing chronic addiction or mental health conditions are often separated from the broader church community and placed into isolated treatment programs, creating a disconnect between recovery efforts and long-term spiritual formation (Amos, 2023). Many churches that emphasize deliverance struggle to provide sustained discipleship, while congregations grounded in spiritual growth frequently lack the skills and structures needed to serve highly vulnerable populations. This mixed–methods study will explore how the local church can be mobilized to offer whole-person transformation for individuals affected by addiction and mental health challenges. Guided by the biblical vision of ongoing spiritual renewal—“being transformed into the same …

How Stress In Pastors May Contribute To Their Resignations, Roger Allen Cooper

Doctoral Dissertations and Projects

Throughout history, congregations have connected with and sought guidance from spiritual leaders. Spiritual leaders develop methods and teachings to aid congregants; however, these leaders often don’t receive the care they give others. Are they not also part of the congregation? It is often assumed that a leader has it all together, but this is not always true. There are many instances of pastors leaving their calling prematurely, although the reason is not always defined. General reasons are often expressed to ease the contention between members or prevent hurting their feelings. Regardless, the result is the same, and there is an …
