This study develops an econometric acreage response model for wheat in the Pacific Northwest (Oregon, Washington, and Idaho) and tests several alternative specifications of risk and their effects on wheat acreage response. Results indicate that the existence of a significant relationship between risk and wheat acreage response depends on the...
This publication collates the published ranges of fuelwood characteristics for 33 conifer and 20 hardwood species in the Pacific Northwest. The following characteristics are covered: specific gravity, percent moisture content, higher heating value, and percent ash of wood and bark; percent bark by volume; and ultimate analysis (percent carbon, hydrogen,...
A technique for solving efficiently the catenary problem encountered in surveying with tapes is presented. The theory of the catenary solution is outlined, and our technique is shown to solve correctly the catenary for all conditions. Analysis of error that compared the catenary correction to the more commonly used parabolic...

The NASA Ames Mars General Circulation Model is used to interpret selected results from the Mars Pathfinder atmospheric structure instrument/meteorology (ASI/MET) experiment. The present version of the model has an improved soil thermal model, a new boundary layer scheme, and a correction for non-local thermodynamic equilibrium effects at solar wavelengths....
An instrument on the Pathfinder lander has been designed to measure the structure of Mars’ atmosphere during spacecraft entry and descent from ~150 km altitude to the surface, and to measure meteorological parameters after landing for the landed duration of the mission. This is specified to be nominally 30 Mars...

Plagiobothrys hirtus is Oregon’s top priority for endangered plant species recovery, and the wetlands of Douglas County provide the only habitat for this plant in the world. The goal is to downlist this species from endangered to threatened, and in order to do that, existing populations must be protected, and...
