Four-fold partially purified glucose-6-phosphate dehydrogenase
(G-6-PDH) from the obligately psychrophilic marine bacterium
Vibrio marinus was effected by thermally induced leakage of the
enzyme, ammonium sulfate fractionation and column chromatography
on Sephadex G-200 gel.
The effects of temperature, pressure, salinity, and pH were
determined for the various degrees of enzyme purity....
Seasonally, in 1998 and 1999, I examined spatial and temporal variation in fish assemblages of agricultural, forested, and acid mine drainage tributaries within the Wayne National Forest (WNF) in southern Ohio. Land use and natural disturbance explained patterns in stream fish assemblages. Creek chub and green sunfish were present in...
Purpose of the Study:
The purpose of this study was to analyze, in the mathematics
classrooms, career-oriented verbal mathematics problems on the
achievement and attitude of the vocational mathematics student.
These career-oriented mathematics problems, used as advanced
organizers, were contrasted with mathematics word problems of a
more abstract and generalized...
A study was performed to assess the uptake and retention patterns
of cesium-134 in the gray-tailed vole, Microtus canicaudus Miller. To
furnish a realistic source of contaminated food for the voles, wheat
seedlings were raised in hydroponic solutions to provide radiocesium
labeled wheat clippings. The hydroponic system was designed to...
The main objective of this research was to determine the professional
in-service development needs of fourth, fifth, and sixth grade
teachers in the metropolitan school districts of Portland and Seattle.
The primary objectives for conducting this research investigation were
as follows:
1. To determine the professional in-service development needs
of...
The purpose of the study was to explore a needs
assessment method for suggesting target-based training
interventions for managing conflict between the resource
user/interest groups in Oregon's riparian zones. An
instrument was developed and then validated by an expert
panel. The questionnaire addressed three potential
conflict management factors: multiple-use orientation,...
Water availability is a controlling factor in stream ecosystems with direct influences on habitat and aquatic ecosystem process, but little work has been done evaluating how biota respond to natural variations in low flow conditions during summer, and which biotic or abiotic features in the system may link most closely...
The creation of a new business venture is a
multidimensional event, but little research has addressed
the interaction of entrepreneurial characteristics and
their relationship to new venture creation. The purpose
of this study was to propose a conceptual framework for
systematically studying the entrepreneurial personality.
The major components of the...
