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...
Observations were made of downward solar radiation as a function of depth during an experiment in the North Pacific (35°N, 155°W). The irradiance meter employed was sensitive to solar radiation of wavelength 400–1000 nm arriving from above at a horizontal surface. Because of selective absorption of the short and long...
Theoretical scattering computations are performed on a phytoplankton model consisting of three
concentric spheres. The outer sphere represents the wall, membrane, or frustule and is assigned a
relatively high index of refraction with no absorption. The middle layer represents the chloroplasts
and is assigned a relatively low index of refraction...
