The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...
To remove small-scale variance and noise, time series of data are generally filtered using a moving window with a specified distribution of weights. Such filters unfortunately smooth sharp changes associated with larger scale structures. In this study, an adaptive low-pass filter is developed that not only effectively removes random small-scale...
A synthetic approach toward the two major fragments of cathedulin K-19,
euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of
dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed
towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran
sesquiterpene, was advanced to a stage in which...
The engineering design process and the advancement of future computer-aided-design systems need new design aids to be used during the conceptual design phase. This design phase is where information gathering and understanding of the problem are developed, analyzed and broken into small more manageable elements. These elements consist of customer...
The U.S. wood window and door industry has experienced much growth
for the past decade. However, to date, little information on factors that could
affect marketing strategies exists. This research represents an initial step for
providing this information.
A mail survey of U.S. wood window and door manufacturers was used...
The primary purpose of this study was t determine the
difference in "career progress" and satisfaction between
cooperative education/internship graduates and non-coop/
intern graduates of a small, private, non-engineering
college. A secondary purpose was to determine which other
independent variables (age; gender; SAT score; GPA; percent
of related work) contributed...
Current research on sport motivation has focused primarily on
goal perspective approaches in an attempt to understand behavior in
achievement situations (Ames, 1984; Nicholls, 1984). According to
Nicholls' (1984) theory, the achievement goal orientation an
individual develops may be influenced by both individual differences
and situational factors.
Relative to situational...
The topic of this thesis is to discuss an
investigation made for a fluid velocity measuring device.
The OSU thermal hydraulic testing facility is interested
in using a small probe to measure fluid velocities in the
annular region of a model nuclear reactor vessel. A
heater with a thermocouple embedded...
This document recreates an historically valuable report prepared by George A Bright in 1914 It
describes an extensive reconnaissance of the Wenaha National Forest that Bright completed in
1913 In addition to narratives about the natural resources, existing uses, and management
opportunities of the Forest, the report includes 42 black-and-white...
Tolerance analysis and synthesis plays a vital role in the success of a product design because it directly affects product quality and manufacturing cost. It also affects manufacturing process selection and planning. This research provides a review of several commonly used assembly tolerance analysis models and evaluation of their limitations....

Deforestation and forest fragmentation are the primary threats to the habitat
of endangered lion-tailed macaques, Macaca silenus, in Karnataka, India. Landsat
satellite images of northwest Karnataka, India, from 1977 and 1990 were analyzed.
Two study sites, measuring 16.35 x 19.14 km (31,213 ha) and 14.34 x 21.44 km (30,561
ha),...
Vegetation along the banks of mountain streams in the western Oregon
Cascades comprises an integral part of the transition zone between land and
water based ecosystems, and as such, is a vitally important and unique natural
resource. Forestry is a major land use in this region, and harvesting riparian
vegetation...
Three aspects of Subsynchronous Resonance (SSR) related problems in power
systems are addressed in this dissertation which aims at contributing to a better
understanding of these problems.
Subsynchronous Resonance (SSR) problems in series compensated steam-turbine
power systems co-exist with the beneficial effects provided by the series capacitors.
Since the early...
This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
Under what circumstances and in what ways can public participation be utilized in managing Finland's
national forests? In the first chapter, a framework for answering this question is set by analyzing Finnish
legal, cultural, historical and political background. The frame defines the Finnish Forest and Park
Service's (FPS) decision making...
Field and laboratory work was undertaken in 1993 to increase understanding of the life history and ecology of the brown jellyfish,
Chrysaora fuscescens, a large semaeostome typically abundant in the neritic regions of the Oregon coast during summer months. Few
medusae were found during 1993, possibly the result of anomalous...
The groundfish trawl fishery operating off the coasts of Oregon
and Washington 1985-1987 caught six major assemblages of species
which could be treated as units in developing mixed-species
management plans. Eighty-one percent of the tows observed on
commercial vessels were consistently placed in one of the assemblage
designations using three...
Tolerance analysis is a major link between design and
manufacturing. An assembly or a part should be designed
based on its functions, manufacturing processes, desired
product quality, and manufacturing cost. Assembly tolerance
analysis performed at the design stage can reduce potential
manufacturing and assembly problems. Several commonly used
assembly tolerance...
Hyphal fragments and protoplasts of two wood-degrading fungi, Postia placenta and Trametes versicolor, were used to examine the effects of two fungicides, copper sulfate and azaconazole, on fungal health (as measured by oxygen consumption, glucose utilization, potassium levels, cell regeneration, and copper uptake). Although both cell systems responded to the...
Involving the public in wildlife management is important to achieve effective and acceptable policies. An accurate assessment of public opinion can be complicated by the public's prior knowledge, perceptions, and the method of public input used. This paper evaluates some factors which may have influenced a public involvement project the...
There are many combinatorial structures which can be regarded as complexes of certain basic
blocks. Familiar examples are involutions, finite graphs, and Stirling numbers of the first and
second kind. Generating functions for these complexes have special forms relating the number
of basic blocks to the number of complexes. Previous...
Alcoholic off-flavor and accompanying volatile compounds produced by bananas (Cavendishii spp) held at 20°C and subjected to aerobic (air control treatment) or anaerobic conditions (nitrogen treatment) were compared by solid phase micro extraction (SPME), a newly developed method for volatile separation. In general, volatile production was suppressed under anaerobic conditions...
The development of a Marine Pollution Monitoring Program (MPMP), in any coastal area of the world, requires a precise knowledge of the functioning of the local ecosystem. Because of the differences found in every coastal ecosystem, it is important to recognize and characterize the reservoirs and significant environments that maintain...
In addition to statistics on bay clams, the report mentions an effort to plant native (Olympia) oysters (Ostrea lurida / Ostrea conchaphila) in Netarts Bay.
The BEST (Benguela Source and Transport) project was designed to investigate the form
of the Benguela Current and ratio of the Aguhlhas Current and South Atlantic Current
source waters masses. The transport of the Benguela Current and its variability was
measured by a moored array of instruments, inverted echo sounders...
Length of survival of the monogenetic trematode Gyrodactylus stellatus in serum and mucus collected from English soles Pleuronectes vetulus at different stages of a laboratory epizootic suggests that both the mucus and serum may be involved in resistance to the parasite. In general, trematode survival was shorter in the serum...
