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...

Equivalence relations on matrices

Creator:: Biegun, Barry Dow
Abstract:: Row equivalence, equivalence, and similarity of matrices are studied; some problems concerning an extension of these relations to infinite matrices are discussed.

The extension problem for functions invariant under a group

Creator:: Chang, Bai-Ching
Abstract:: Consider a transformation group G operating on a space X and a G- invariant function f defined on a G- invariant subset of X. By imposing suitable conditions on X, G, f and A, the author derives sufficient conditions for extending f invariantly to the whole space, and thus generalizing...

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...

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...

The automated inference of tree system

Creator:: Levine, Barry Arthur
Abstract:: Tree systems are used in syntactic pattern recognition for describing two-dimensional patterns. We extend results on tree automata with the introduction of the subtree-invariant equivalence relation R. R relates two trees when the appearance of one implies the appearance of the other in similar trees. A new state minimizing algorithm...

Trichoderma spp. : distribution in stumps infested with Phellinus weirii and growth and antagonism in vitro

Creator:: Goldfarb, Barry
Abstract:: To determine which isolates will most rapidly replace Phellinus weirii in stumps and roots, Trichoderma spp. were isolated from P. weirii-infested stumps and roots, identified, and examined for growth rates and lethal effects on P. weirii in vitro. Phellinus weirii-infested Douglas-fir stumps and stump roots were sampled for microorganisms by...
