Creator:: Sumich, James L.
Abstract:: Allocentrotus fragilis (Jackson) was obtained from six stations at depths of 100 to 1260 m on the continental shelf and upper slope off Newport, Oregon. Ages and growth rates of A. fragilis were determined by two methods: 1) A procedure was developed to make growth zones of the skeletal test...

Creator:: Guthrie, J. L. (James Leonard), 1937-
Abstract:: 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...
