Five Promises More Powerful Than Fear, Trevor A. O'Reggio

All Books

---

The genesis of this book grew out of an unforgettable experience with students from the SDA Seminary at Andrews University during the summer of 2023, when we traveled to Zambia to conduct a series of evangelistic meetings. Each day, I encouraged the students to memorize and recite Isaiah 41:10 as a source of courage, strength, and inspiration. That powerful verse became a daily reminder that God’s presence is greater than any fear or challenge we may face.

After returning from Zambia, I felt impressed to preserve the impact of that experience by writing this small book based on Isaiah 41:10. …

Gradual Disordering, Billie June Brand

Art and Art History Honors Projects

---

My Studio Art Honors Project engages the grid as a contradictory format: one that simultaneously represents empirical order (graphs and maps), and a domestic visual language that rejects a single point of view (weaving). Gradual Disordering exists within this tension: referencing cluttered interior space, non-linear organizations, and repetition as world-building. I layer materials–photos, archival images, and journal pages–into multiple woven, painted, and ceramic abstractions. Nest-like objects perch out of reach, viewed from below. Large-scale grids and paper weavings warp in space, looked at and looked past. With additions and deletions in each iteration, the grid continually changes.

Impact Of Land Use On Soil Properties, Clay Mineralogy, And Behavior Of Ammonium Across A Precipitation Gradient, Isabel Delamater

Theses and Dissertations--Plant and Soil Sciences

---

Like soil texture, clay mineralogy is considered a permanent or inherent characteristic of soils reflecting the influence of soil forming factors over long periods of time. Despite the importance of clay mineralogy in providing ecosystem services, much remains unknown about whether land use (native grassland sod versus no-tillage) can modify clay mineralogy under short periods of time. Furthermore, in no-tillage agroecosystems, lower crop yields are often ascribed to immobilization of added N fertilizer where inorganic nitrogen (such as ammonium) is converted to organic nitrogen. The possible role of clay mineralogy in retaining added ammonium has been overlooked in no-tillage systems. …
