Creator:: Sarkar, Aveek, 1974-
Abstract:: Radiation studies were performed on compound semiconductor heterostructure devices. The objective was to understand the degradation processes caused by the exposure of these devices to radiation. Preliminary experiments were focussed on studying the degradation phenomenon in single heterojunctions and single quantum wells. It was found that ionizing radiation like gamma...

Creator:: Boone, Darren M.
Abstract:: Exposure to moderately high levels of ionizing radiation (<20 Gy) has in some instances shown a hormetic effect in numerous vegetable-type crops. Past experiments performed in outdoor cultivars have shown a somewhat unpredictable increase in growth rate with a higher overall yield in a specified time when the seeds are...

Creator:: Tami, Mohamed
Abstract:: Five nutritional aspects of 'Valencia' orange production in Agadir, Morocco during 1989-1991 were evaluated: 1) the effect of N and K on yield and fruit quality, 2) leaf sampling time and diagnostic approaches to optimize mineral nutrition, 3) mass and mineral partitioning within individual trees, 4) K-Rb relationships, and 5)...

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

Creator:: Bostick, Kent C.
Abstract:: The ion implantation process is a very precise, controllable, and reproducible method used to enhance material properties of finished components such as ball bearings. Essentially, the target material is bombarded by accelerated ions to form a thin alloyed layer in the substrate. As the ions deposit their kinetic energy in...

Resource Type:: Dissertation
Full Text:: Doctor of Philosophy in Genetics presented on December 17, 1992. Title: Isolation and Characterization

Creator:: Govier, R. D.
Abstract:: The inert gas ion bombardment of solid surfaces has found many uses in the field of analytical chemistry. In one method of spectrochemical analysis, inert gas ion bombardment in a glow discharge is used to produce an atomic vapor, representative of the sample bulk, which is analyzed using atomic absorption...
