and timing of depositional sequences, the sediments...
Forest recreation is one of the many non-commodity functions of forests that have
experienced a rapid growth in demand in the past few decades. Even faster growth in
demand for recreation is expected for several decades. However, such growing demand
for forest recreation is often not well perceived by owners...
The main objective of this thesis was to determine the influence of tree vigor on susceptibility to Armillaria root disease. First, the effect of thinning, fertilizing and pruning on tree vigor of four young Douglas-fir (Pseudo tsuga menziesii var. menziesi,) plantations was explored. Tree vigor was calculated by measuring wood...
The goal of these experiments was to ensile combinations of shrimp or crab waste
with perennial ryegrass straw and analyze it for silage quality and ruminal degradability.

Three-dimensional gravity analysis is the process of removing the predictable
components from the free-air gravity anomalies and has proven to be useful for
interpreting the subsurface structures and active processes at mid-ocean ridges. The
three-dimensional effects of the seafloor and Moho topography, assuming a constant
crustal thickness and constant crust...
Abraham Heschel wrote that a philosopher's primary task was not merely to describe and judge the modes and facts of actual human behavior, but also to examine and understand the meaninq of those descriptions and judgements of modes and facts (Bella, 1978). Our values are critically tied to our structures...
The cell survival curve is the only means by which to both qualitatively and
quantitatively assess morphologic alterations directly resulting from in vitro irradiation of
the cell. A ⁶⁰Co cell survival curve experiment has successfully demonstrated the
response of the AtT-20 clone mammalian cell line to the effects of gamma...
Transitional areas between upland and aquatic habitats, commonly known as
wetland, were once viewed as unproductive areas and were drained for farming or
pasture. Wetlands are now accepted as significant ecological resources, and their
protection is a mandate of federal, state, and local land managers. Due to the
diversity of...
The study of the social dimensions of Shakespeare's art is represented by the work of Mikhail Bakhtin, C.L. Barber, Robert Weimann, Edward Berry, and Michael Bristol. Their work analyzes the background in Elizabethan social practices and popular dramatic traditions that contribute to the form, structure, and meaning of Shakespeare's comedies....
Cellular Manufacturing Systems (CMS) have provided
significant increase in manufacturing productivity over the
last two decades. This has been achieved because CMS can
overcome the problems due to frequent setups, high in-process
inventories, long throughput times and complex
planning and coordination commonly associated with a batch-type
manufacturing operation. The underlying...
The self-efficacy construct has been determined to be an effective method of
stimulating desired eating behavior in diabetics and obese adults and exercise behaviors in
pulmonary rehabilitation patients. Although the self-efficacy construct has been shown to
mediate eating habits, practical classroom application of the construct has been rarely used
in...
This study examines empirically the relationship of value
orientation to meanspiritedness. Meanspiritedness (a collection of
acts, thoughts and/or attitudes which are intentionally malicious)
was defined and a scoring method was designed. The management
level of self-interest in individuals as indicated by their value
orientation and religious orientation was examined. Additionally,...
The present study examined the influence of the
demographic variables of age, gender, major in college, and
level of education or class standing on individuals' stage
of moral development. Trevino's interactionist model,
combined with the basic principles of cognitive moral
development, provided the theoretical basis for this study.
One-hundred and...
The hop (Humulus lupulus L.) is a dioecious, diploid (2n=2x=20) species. Triploid
hops (2n=3x=30) are easily obtained from tetraploid by diploid crosses and are preferred
because of their natural seedlessness and increased vigor. The female inflorescence is used
for flavoring beer. Because brewers require product consistency, the brewing characteristics
of...
Anthesis of both staminate and pistillate flowers of Corylus occurs in midwinter. To insure adequate pollination and nut set, these flowers must attain a sufficient hardiness level to withstand low temperatures. This study estimated cold hardiness of Corylus cultivars and species using laboratory freezing of shoots without artificial hardening. In...
This study examines the impact on Pacific Northwest
seafood exporters of the European Union Directive on packaging
and packaging waste management.
