A set of simulations with the NASA Ames Mars general circulation model (GCM) has been analyzed to define the basic properties and dynamics of quasi-stationary eddy circulations in the winter hemisphere. These circulations, differing substantially from those in low latitudes and the summer hemisphere, extended from the surface to the...
The NASA Ames Mars general circulation and boundary layer models are used as guides to forecast the meteorological environment of the Pathfinder lander site. Based on these models we predict that for a Viking-like atmospheric dust loading, significant vertical wave structure will be seen in the entry temperature profile above...
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....
A large number of bacterial and yeast isolates were obtained
from meat and poultry processing plants by swab and contact plate
sampling methods. Most of the isolates were subjected to a brief
taxonomic study and listed according to their sources. Representative
food spoilage, indicator and pathogenic organisms were identified
In order to determine the source of bacteria in Tillamook Bay,
Oregon, water samples were collected monthly for six months during
the rainy season from October 1975 through March 1976 from the bay
and its tributaries, the Kilchis, Trask, Tillamook, and Wilson
Fecal coliform levels of these samples were...
The use of the exponential-transfer-characteristics of a transistor
junction as a means of giving a logarithmic sweep calibration to a
sampling oscilloscope is presented. The prior work in logarithmic
converters leading up to the use of the transistor's transfer properties
is explored. A circuit adapting a sampling oscilloscope to a...
Two studies were conducted to determine the effect of varying vitamin B-6 (B-
6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP)
concentration in peripheral blood mononuclear cells (PBMC) in young women. In the
first study, women were fed 1 mg/d for the first week and 1.5, 2.1 and...
