Electric power needs will only grow over the next decades as more humans ascend from poverty into the middle class. Currently, the majority of electric power is generated by burning fossil fuels. To help mitigate the undesirable effects of burning fossil fuels research is being done to increase the efficiency...
Andic soils (aka Andisols) have unique properties that are important to society. For soil scientists, the genesis and taxonomy of Andisols is often confused because they can form in both volcanic and non-volcanic material. This dissertation seeks to address such confusion by looking at andic soil development in the Cascade...
This dissertation reports on four related, though separate projects. The first project details the process of carrying out a digitally augmented soil mapping (DSM) effort alongside an ongoing survey in Oregon's Ochoco National Forest (ONF) using a Random Forest algorithm. The second chapter describes a initial soil survey in Oregon's...
The yeast two-hybrid system was used to examine
interactions between the nine proteins involved in baculovirus DNA
replication. From the six proteins required for DNA replication,
four protein-protein interactions were identified, including an
interaction between LEF-1 and LEF-2, LEF-3 and itself, LEF-3 and
P143 (Helicase), and an interaction between IE-1...
Stream discharge is a key water balance component and important factor in global change evaluations. Nevertheless, the mechanisms for streamflow generation are poorly understood. Near- stream surface saturation during precipitation events is one of the most iconic, visible indicators of rapid runoff production in upland humid catchments around the world....
Firefighting is a very hazardous profession. Firefighters experience an injury rate that is three times higher than other physically demanding professions and the death rate in the fire service is also much higher compared to typical. Throughout the literature, data suggest the physical nature of firefighting contributes to the high...
State-and-transition models (STMs) have been successfully used to
describe ecological dynamics in woodlands, shrublands, grasslands, and several other ecosystems. Changes in vegetation and soil are measured to gauge and predict plant community dynamics within ecological states and transitions between alternative ecological states. Ecological states and their boundaries are defined by...
Work-related hazards and exposures affect human health and well-being. Occupational Safety and Health (OSH) surveillance is fundamental to the public health approach. OSH surveillance provides important data on the occurrence and magnitude of the problem and risk/protective factors. A wide variety of OSH surveillance programs and systems have been established...
This dissertation serves as a contribution to the study of the prehistory of the Central Desert region of Baja California, Mexico. Between 2007 and 2011, a trans-peninsular archaeological survey and excavation program―the Central Desert Early Prehistory Project (CDEPP)―was completed for a portion of the Baja California peninsula extending from the...
