The development of bioenergy from biomass has dominated the minds of forest engineering researchers over the last decade. One of the main themes that has been generated from that research is that bioenergy from biomass has major operational hurdles to overcome before becoming economically feasible. More directly, the impact of...
Angry driving behaviors that lead to acts of road rage have become a major public health concern. Understanding the differences between people who drive with a high level of anger and those who do not provides insight into possible prevention approaches. This study applied Richard Lazarus' Cognitive-Motivational-Relational (CMR) Model to...
The study of the subsurface flow and distribution of water is critical to the
evaluation of the unsaturated zone for a potential geologic high-level radioactive
waste repository. This site is located at Yucca Mountain, Nevada in the northern
Mojave Desert. and was chosen on the basis of its low precipitation,...

Land-use change in forested regions of the tropics is currently one of the largest
anthropogenic perturbations on earth; it is a force capable of altering biogeochemical cycles at local, regional, and global scales. However, significant uncertainties exist concerning the impact of land-use change on biomass and elemental pools of tropical...
Natural hydraulic barriers exist at Yucca Mountain, Nevada, a potential high-level nuclear waste repository, that have been identified as possible lateral diversions for reducing deep percolation through the waste storage area. Historical development of the conceptual model of lateral diversion has been limited by available field data, but numerical investigations...
Measurements for water retention calculations and physical
characterization were made on skeletal and non-skeletal soils in
southwest Oregon. A new bulk density sampler was designed for the
physical characterization of the steep, skeletal soils commonly
encountered in this area. The new sampler and the techniques
required for the measurement and...
In order to develop three models for use in quantifying the
environmental conditions of reforestation, extensive measurements
required for energy balance calculations were taken for a
reforestation site in southwest Oregon. The models are used to
decrease the number of measurements required to properly evaluate
the potential for heat or...
A two year study with 500 seedlings was conducted
in the harsh, drought prone southwest Oregon
environment to assess the effects of 12 soil surface
shading, mulching and vegetation control techniques on
soil temperature and moisture environments and seedling
growth. Treatments modified, to various degrees, soil
surface temperatures, reduced soil...
Luteinizing hormone (LH) is secreted in low-amplitude pulses in sexually intact dogs to stimulate synthesis of estrogen and testosterone in females and males, respectively. LH is mainly considered a reproductive hormone, but LH receptors (LHR) have been identified in non-reproductive tissues, including in canine lymphoma and isolated canine T-cell lymphoma...
Natural products have long been an important source of resources for humans. Many of these compounds possess unique chemical structures and potent biological properties. By targeting natural products with specific chemical properties, we can gain a better understanding of the roles these compounds play in the environment and their interactions...
