The main purpose of this research is to provide the
commercial seafood industry of the Pacific Northwest
information on preferences of restaurateurs, retailers, and
wholesalers for whole albacore, low-value added albacore
products (chunks, medallions, and steaks), albacore loins,
and high-value added albacore products (hot smoked and lox).
All of these...
Tuna fishery is an important activity worldwide. In the
eastern Pacific Ocean the effort applied by the Pacific Ocean
fleet to catch tuna fish is considerable. The eastern Pacific
tuna fleet harvests throughout the oceans and captures an
important fraction of this resource. For instance, in 1980 the
total catch...
There is no information available on water management of birdsfoot
trefoil grown for seed. Information is also not available describing how to
minimize seed losses due to shattering in order to obtain consistently high
birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify
crop water use,...
Red radish anthocyanin extract (RAE) was investigated for coloring brined
cherries as an alternative to FD&C Red No. 40. Red radish (Raphanus sativus L.)
anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using
acetone, partitioned with chloroform, and isolated using C-18 resin. The monomeric
anthocyanin content was determined by...
Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid
nitrogen powdered epidermal tissue using acetone and chloroform and isolated using
C-18 resin. Chemical structure and conformation of major pigments were elucidated
by 1-D and 2-D NMR, Mass Spectroscopy, HPLC, and spectral analyses. Two novel
di-acylated anthocyanins, pelargonidin 3-0-[2-0-(β-D-glucopyranosyl)-(6-0- trans-p-coumaroyl-...
This thesis outlines dominant ideologies and practices that affect women's authority in the urban social milieu of north India. Theories that consider the causes of social stratification by gender as well as social movement patterns are useful for understanding the durability of gender roles. The utility of these theories for...
This study describes the composition of forest landscapes surrounding
northern spotted owl (Strix occidentalis caurina) nests in the central Cascade
Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair
territories with forest composition around 119 points drawn randomly from all
terrestrial cover-types, and around 104...
Unknown questions remain concerning the health of migrant farm workers,
seasonal farm workers, and other rural poor people. The objectives of this study were to
determine the demographic profile of a sample from a Community and Migrant Health
Center; to determine the prevalence of disease in migrant farm workers, seasonal...
This is a bibliography of doctoral dissertations and masters' theses in forestry and related topics issued during the period from July 1981 through June 1990. The colleges and universities included are all accredited by the Society of American Foresters. The actual listings were supplied by the individual institutions. Topics covered...
Rainbow trout cystatin C cDNA has been isolated from
trout liver. The full-length cystatin cDNA (674 bp)
included the 5'untranslated region and the polyadenylation
signal sequence AATAAA in the 3' region. Translation of
the cDNA defines 132 amino acid residues. Comparison of
the amino acid sequence with those of family...
Pacific whiting and its by-products were good raw materials for high quality fish sauce production. Heat stable and salt activated enzymes were responsible for autolytic activity in Pacific whiting and by-products. According to temperature profiles of raw materials at various salt concentrations, two fermentation temperatures, 35°C and 50°C, were selected...
Changing demographics in Oregon, accompanied by a rising Latino population, serve to dispel myths that we live in homogeneous, monolithic communities. Migration studies indicate migration is reshaping communities, contributing to ethnic diversity thus challenging our notion of identity and culture. Through the medium of oral histories and ethnography, this study...
Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat
production in the Pacific Northwest. Development of resistant cultivars has been
hindered by the lack of adequate levels of genetic resistance and screening techniques
which can consistently detect desired genotypes.
Studies were conducted to determine if the reported...
The success of the U.S. government in persuading Japan to
liberalize the beef market is viewed as a relief to the U.S.
beef industry. The economic benefit (to the U.S. beef
producers!) of the trade liberalization however is yet to be
seen. The size of this benefit is determined, among...
This thesis research is a series of five studies dealing
with various aspects of hazelnut quality:
1. Identification of kernel mold and its incidence among
hazelnut varieties.
2. Seasonal development and composition of kernels.
3. Hazelnut oil composition (fatty acids and
tocopherols) of seventeen varieties.
4. Hazelnut oil composition compared...
The objective of this research was to improve our understanding of how
changes in the environment affect ecological processes. Change detection is often
confounded by the large variation found in ecological data due to the difficulty of
finding replicates in nature. Intertidal communities were chosen for studies of biophysical
interactions...
During the U.S. military interventions in Nicaragua, the Dominican
Republic, and Haiti between 1915 and 1934, Washington equipped
members of the its armed forces with civil and political powers that
represented a radical departure from the North American military tradition.
This abandonment of tradition decisively contributed to both the
disappointments...
This thesis is the first of three sections in what will be a book-long project of creative nonfiction essays. The book will parallel the author's diary with three other family diaries, spanning four generations. This thesis deals with the first of those diaries, written by Antonio Bonetti's, the author's great-grandfather....
Environmental contamination along roadways with lead from processed
petroleum and automotive residues has been reported. Toxicity to the herbivores grazing these areas has not been well studied. Comparison of lead concentrations adjacent to roads in Kuwait and in Oregon, USA was studied. Soil samples were taken from three sites at...
Fusion reactions with radioactive neutron-rich projectiles have been the subject of much recent theoretical and experimental interest. Predictions of enhancement of the cross section due to the use of a neutron-rich projectile may have implications for synthesis of heavy nuclei. In this work, the fusion-fission excitation functions were measured for...
This thesis presents a discussion of the main materialistic theories proposed to explain the process of development among the indigenous population of Latin America. Four theoretical approaches are presented and discussed. The first one deals with the social group referred to as peasants. The second one explains the process of...
The first committed step in DNA biosynthesis occurs by direct reduction of
ribonucleotides. This reduction is catalyzed by ribonucleotide reductase (RNR), an
enzyme which uses a unique radical mechanism to facilitate the transformation. All four
DNA precursors are synthesized by a single enzyme. Therefore, an intricate pattern of
regulation has...
Throughout the 20th century, windthrow has affected forests in the Bull Run watershed, a 26,500 ha basin that is the principal water source for the city of Portland, Oregon. Windthrow from storms in 1973 and 1983 was mapped into a geographic information system (GIS) and compared to a 1931 windthrow...
The Forest Service and the Bureau of Land Management propose to adopt coordinated ecosystem management direction for the lands they administer within the range of the northern spotted owl. This Supplemental Environmental Impact Statement (SETS) presents as alternatives the options, with slight modifications, developed by the Forest Ecosystem Management Assessment...
