Bacterioplankton in the Oregon upwelling system: distribution, cell-specific leucine incorporation, and diversity

Creator:: Longnecker, Krista
Abstract:: Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...

The relationship of instructional delivery methods and individual differences to the training of operators of computer systems

Creator:: Kluge, E. Alan
Abstract:: The objectives of this study were to: (1) determine if individual differences in the learner characteristics of field dependence, state and trait anxiety, age, sex, and prior computer experience were related to performance in operating a computer system; (2) to determine if differences in performance would occur as a result...

Design techniques for low-power electrical and optical serial link receivers

Creator:: Bai, Rui
Abstract:: As computation power continues to grow, the demand for data transfer bandwidth is also rising. This is reflected in the increasing data-rate of high-speed links. However, the increase in data-rate is sustainable only if the I/O energy efficiency improves as well. This dissertation explores several techniques to enable high-speed links...

New application of crystalline cellulose in rubber composites

Creator:: Bai, Wen
Abstract:: Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

Factors affecting adventitious shoot formation and expression of microprojectile-introduced DNA in Douglas-fir cotyledons

Creator:: Goldfarb, Barry
Abstract:: Our goal was to develop knowledge that will enable insertion of foreign genes into Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] trees. This required improvement of a tissue culture system for producing adventitious shoots from cotyledons, and study of factors affecting gene delivery, expression, and analysis. Administering a short-duration, concentrated liquid pulse...

Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...

The effect of preplant nitrogen fertilization and soil temperature on biological nitrogen fixation and yield of alfalfa (Medicago sativa L.)

Creator:: Shuler, Philip E.
Abstract:: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...

Development of a model for context evaluation of community college competency-based curricula

Creator:: Noonan, Arthur Barry
Abstract:: Purpose of the Study: The purpose of this study was to develop and field test a model for context evaluation of objectives used in competency-based curricula at the community college level. The study: 1. Developed a decision and information matrix that identified objectives which should be considered for deletion from...
