The thesis was an investigation into the mechanism of precipitation
from solid solution in an Aluminum-0.7% Magnesium-0.6%
Silicon alloy containing iron impurities. Laue x-ray diffraction patterns
were obtained from solution heat treated and aged single crystal
specimens in various crystallographic orientations. Precipitation
related streaking was detected on some of the...

This publication identifies and describes the natural occurring plant associations within the central Oregon Pumice deposition zone. A dichotomous vegetation-site key is provided toward the front of the publication to assist administrators and field personnel in on-site identification of the associations. The descriptions are grouped according to similarities in dominant...
A pest management program for variegated cutworm (VC), Peridroma
saucia (Hubner), in Oregon peppermint was developed based on studies
of pheromone trapping, sampling methods, and economic thresholds.
Pheromone traps effectively trapped VC males and were used to
reflect development and oviposition trends. Trap height was linearly
correlated to moth catch...
Beer, nonfat dry milk, fried bacon and microwave baked fish were
treated under simulated gastric and extreme nitrosation conditions to
estimate their capacity for generation of endogenously formed
N-nitrosamines. The level of nitrosamines in beer increased from 0.1
ppb N-nitrosodimethylamine to 0.4 ppb N-nitrosodimethylamine (p < 0.05) under simulated gastric...
This investigation was designed to analyze change in critical .
thinking between students in laboratory-centered and lecture-demonstration-centered patterns of instruction in high school biology.
Twenty biology classes were randomly selected from the four
senior high schools in the Salt Lake City School District. Class enrollment
ranged from nine students in...
