251. [Article] Quench Factor Characterization of Steel Hardening: A Review
A quench factor, Q, has been derived that quantifies the overall severity of the steel hardening process—quench severity by interrelating steel hardenability with quenching variables including: the specific ...Citation -
252. [Article] Regeneration Patterns and Facilitation Following Blowdown in a Self- Replacing Lodgepole Pine (Pinus contorta) Stand in Central Oregon
Nurse plant and object facilitation is an important factor mitigating abiotic stress, improving seedling recruitment, and shaping the fine-scale spatial patterns of many plant communities. I investigate ...Citation -
253. [Article] An Empirical Study of Particulate Matter Exposure for Transit Users at Bus Stop Shelters
Congested traffic corridors in dense urban areas are key contributors to the degradation of urban air quality. While waiting at bus stops, transit patrons may be exposed to greater amounts of vehicle-based ...Citation -
