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....
Mariner 9 and Viking spacecraft observations provided evidence for planetary-scale, wavelike disturbances in the Mars winter atmosphere. Possible sources of the wave activity are dynamical instabilities, for example, barotropic and / or baroclinic instabilities. Other candidate sources are forced. quasi-stationary planetary waves—waves that arise predominantly via zonally asymmetric surface properties....
Mariner 9 and Viking spacecraft observations during the 1970's have provided
evidence for planetary-scale wave-like disturbances in the Mars atmosphere. It has
been suggested that possible sources of the wave activity are dynamical instabilities
(e.g., barotropic and/or baroclinic instabilities). An other candidate source is forced,
quasi-stationary planetary waves. In connection...
The purpose of this dissertation was to add to the professional literature in counselor education and supervision through inquiry and synthesis of research among online teaching, online counseling, and online communities of practice through the supervision lens of the Discrimination Model. A unique, research-informed framework for synchronous online supervision (i.e.,...
During the summers of 1975 and 1976 a sedimentation study
was conducted in the Bear Creek watershed, located in the southeastern
corner of Crook County, in central Oregon. The Rocky
Mountain infiltrometer was used to simulate high intensity rainfall
over 468 sedimentation plots. Rainfall and runoff were measured
and a...
A sensitive assay for the analysis of contaminating segments
in pseudorecombinants constructed from a seed-transmissible (CVM-Pg)
and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic
virus was developed using partial RNase T₁ digestion. Isolated
genomic RNA segments produced unique digestion patterns when 3'-
end labeled, treated with RNase T₁, and subjected...
This paper will identify selected biological, economic and political aspects of mountain pine beetle management
decisions. It has been developed to aid in determining if action should be taken to manage mountain pine beetle
attacks, and if action is taken, what type of action is most appropriate.
The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...
Large-scale engineering systems provide important functions and at the same
time address serious concerns to human society. Because of the complexity and
resources involved, the development of these systems is currently a challenging
undertaking. In this work, an axiomatic design approach, based on Suhs axiomatic
design theory, and combined with...
Grazing of riparian forage by livestock may alter stream channel morphology in ways that impact nearby aquatic habitat, bank stability, vegetative cover and water quality. A number of grazing management practices have been proposed as a means to reduce the amount of time cattle spend in the riparian zone. The...
