Letter from Sister to T.J. Edson, 1865 April 10
No full textT.J. Edson fought with the 38th Iowa Infantry during the Civil War in the course of which he was stationed at Vicksburg, Miss. and later at Brownsville, Tex. Edson wrote copiously throughout the War to his family in Iowa. He was married (1858) to Amine Woodward whose family had intermarried with the Underwoods and had been friendly with the Blisses.https://scholarlycommons.pacific.edu/civil-war/1023/thumbnail.jp

Ion Thruster
No full textPropulsion systems for long-duration aerospace missions are fundamentally constrained by fuel mass and engine longevity. Ionic propulsion offers a promising alternative by utilizing high-voltage electrostatic ionization to generate thrust with minimal propellant usage. This project presents the design, simulation, and construction of an ion wind propulsion demonstrator, integrated with a microcontroller-based control system for thrust vectoring and performance telemetry.
The propulsion architecture is driven by a multistage high-voltage system designed to achieve a potential difference of approximately 50 kV. The full power stage was modeled in PSpice, beginning with a 5 V DC input stepped up through a DC-DC boost converter feeding a single-transistor self-oscillating flyback resonant driver (informally known as Slayer Circuit), followed by a multi-stage Cockcroft–Walton voltage multiplier. For the physical prototype, a commercial high-voltage module with comparable output characteristics was integrated to comply with campus safety protocols while validating the electrodynamic ionization behavior predicted by simulation. The resulting high-voltage field is applied across a custom emitter–collector grid, stripping electrons from atmospheric gas and accelerating ions to produce ionic wind without moving mechanical components.
A key contribution of this project is the integration of a digital control layer. An Arduino-based microcontroller serves as the primary computing unit, coordinating airflow sensors, electromagnetic field monitoring, and system-status telemetry. The controller implements a closed-loop logic scheme to regulate a servo-actuated vent, enabling adjustable thrust direction. All structural components - including electrode supports, dielectric housing, and vent assemblies - were designed in CAD software and fabricated using 3D printing to ensure precise electrode alignment and safe containment of high-voltage circuitry.
Experimental testing confirmed consistent ionic airflow exceeding 4 m/s, demonstrating the viability of a compact, solid-state propulsion system that merges high-voltage physics with embedded control. The resulting platform provides both a functional thrust demonstrator and a foundation for future research in high-altitude endurance drones, autonomous electrostatic propulsion systems, and next-generation ion wind technologies
And Yet She Persisted: An Autoethnographic Exploration of a Mature Doctoral Student Experiencing Grief and Loss During the Doctoral Journey
No full textThis evocative autoethnographic study explored the lived experiences of a mature doctoral student navigating grief and loss while progressing through a doctoral program. The research connected the personal narrative of the author a nurse, educator, wife, mother, and widow to broader themes of resilience, identity, and persistence in higher education. Using narrative inquiry and self-reflective vignettes, this dissertation sought to illuminate how grief intersects with academic life, shaping both personal meaning and scholarly perseverance.
The study was guided by four research questions: (1) What does it mean for the mature doctoral student to be successful in negotiating the doctoral journey while experiencing grief? (2) What challenges emerged during this process, and what factors contributed to overcoming them? (3) What can other doctoral students learn from this experience to support their own persistence? and (4) What can doctoral faculty learn from this narrative to better assist grieving students in the successful completion of their doctoral program?
Grounded in grief theory (Neimeyer, 2000) and resiliency theory (Richardson, 2002), the study used autoethnography to explore the meaning-making process of loss and the role of resilience in academic persistence. Data were derived from personal journals, coursework reflections, and field notes collected over several years, culminating in a series of vignettes that illustrate themes of humor, community, grief, and perseverance.
Findings revealed that grief, while profoundly disruptive, can also serve as a catalyst for growth, self-understanding, and renewed purpose. Supportive peer relationships, faculty compassion, and the use of humor emerged as protective factors that enhanced resilience. The study underscores that for mature doctoral students, persistence is often an act of healing—an embodiment of resilience cultivated through adversity.
Implications for higher education include the need for trauma and grief-informed approaches to doctoral mentoring, the creation of communities of practice to reduce isolation, and the recognition of grief as a significant but navigable aspect of doctoral persistence. This research contributes to the limited literature on mature adult learners in higher education and highlights the transformative potential of storytelling as both scholarship and self-preservation
