Western Atlantic synodontid species were studied as part of an ongoing effort to reanalyze Caribbean shorefish diversity. A neighbor-joining tree constructed from cytochrome c oxidase I (COI) data revealed 2 highly divergent genetic lineages within both Synodus intermedius (Agassiz, 1829) (Sand Diver) and S. foetens (Linnaeus, 1766) (Inshore Lizardfish). A...
The biochemical composition of ten species of estuarine phytoplankton
was determined. Studies were made of their growth in
various culture media and of their relative value as food for oyster
larvae. Nine of the species were isolated from Yaquina Bay, Oregon.
An attempt was made to select species which commonly...
This investigation was undertaken to determine 1) the effects
of various carbon sources in defined media on pectolytic enzyme production,
2) the effect of the incubation period on pectolytic enzyme
activity, and 3) the development of improved methods for the purification
and characterization of the polygalacturonases (PG) produced
by Fusarium...
The objectives of this study were to 1) develop a relatively quick staining procedure that would detect incipient decay by color differentiation under fluorescence, 2) quantitatively assess the amount of decay present with the use of an image analyzer, and 3) re/ate loss in strength at various decay levels to...
While water scarcity and energy demand are continuously increasing in the world, alternative sources are needed to meet the requirement of a growing population. Microbial Fuel Cell (MFC) is a sustainable technology that converts organic matter in wastewater into electricity, thus it can be a potential alternative source for water...
The purpose of this study was to isolate and characterize any
segregants of the heterogenotes formed from sexduction by an F'
donor. Following the mating of F' W4520, carrying an F' gal₁⁺
gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of
recombinant clones were picked and examined for...
This study examines two major issues: (1) to what extent have the
conditions at non-reservation Indian boarding schools, as described by
the Meriam Report of 1928, been in evidence from the beginning?; and
(2) to what extent have these conditions improved since 1928?
The conditions examined are: (1) General Conditions...
The purpose of this annotated bibliography is to guide middle school and high school students into critical thinking about environmental issues. Through keen observation of their bioregion and through an integration of interdisciplinary literature which focuses on Oregon writers, students will be challenged to think, write, and discuss current issues...
Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...
A recent article by Cozzi and Kelliher [3] has demonstrated a sense of "locality" to the incompressible Euler equations which mirrors physical fluid behavior. We further develop the corresponding notion of "damping," and identify both temporal and local damping behaviors. To represent this problem, we perturb the initial condition of...
As with other areas of the curriculum home economics
tends to respond to the objectives of powerful interest
groups rather than to the work of recognized scholars and
the ideals of democracy.
The philosophical orientation of this study is derived
from the work of Jurgen Habermas, a dominant figure in...
A study was made on the effect of CCC (2-chloroethyl)-trimethyl-ammonium
chloride), a plant growth retardant, on the RNA (ribonucleic
acid) content of wheat plants, It was found that the RNA content of
wheat leaves generally decreased with increasing levels of CCC up to
1x10⁻⁵M. Thereafter, the RNA content again increased...
My thesis examines how the American identity is constructed through thinking shaped by deception and domination, as James Baldwin argues in the corpus of his work. I rely on the work of Eddie Glaude Jr., Sean Kim Butorac, and Joel Schlosser to forward love in Baldwin’s political vision as being...
Mesoscale physical oceanographic features, such as jets and eddies, can influence the structure of marine ecosystems. We used trophically transmitted parasite communities of pelagic fishes in the northern California Current to examine effects of physical oceanographic features on pelagic ecosystem structure. We tested the hypotheses that (1) oceanographic features associated...
There is an urgent need to clarify how different stocks, or subpopulations of fish species, are vulnerable to fishing pressure and unfavorable ocean conditions because of the increasing demand on fisheries for human consumption. For marine fishes, the potential for high gene flow increases the difficulty in determining the number...
My thesis examines perceptions of power in relation to white and black masculinity in the United States. The introduction invokes the work of Mireille Miller-Young, Hortense Spillers, Vincent Woodard and Hiram Pérez as a foundation to ground my discussion of agency, consumption, desire, homoeroticism and the characteristics of the Mandingo,...
Dans un marché de libre concurrence, certains paramètres tels que la saison de pêche et la taille des produits halieutiques ont une très grande importance sur la fixation des prix et la volonté à payer du consommateur. Afin de valider ces données, des échantillons de palourdes de l'Atlantique (Spisula solidissima),...
The quest from tourists and visitors for authentic places with a real identity can lead to an opportunity to maintain some fishing activities at the seaside. In this context, fishing activities not only provide commodity goods but also have other functions (environmental, social, and territorial, among others). In this respect,...
A summary of one phase of a direct observational program conducted
in the coastal region off Oregon is presented. The measurements were
made primarily on the continental shelf in late coastal upwelling season
(August and September 1966). The principal measurements were time
series of horizontal current velocity and temperature fields;...

In the context of the restriction of production, French agriculture modifies its activities by developing multifunctionality. This concept translates the fact that, beyond the saleable production of agricultural and food processing products, the agricultural activity fulfills other functions: economic, social, environmental. Multifunctionality of agriculture is implemented in a number of...
While French marine fisheries must cope with increasing difficulties, the concept of
multifunctionality of fisheries (as previously observed in agriculture) is emerging
through a diversification of activities. Indeed, fishers resort to alternatives in order to
sustain their activity by calling on new ways to interact with environment, institutional
players, scientists,...

Conservation conflicts may develop on restoration sites with multiple species recovery objectives. For example, on Pacific Northwest prairies, the co-planting of the diploid cytotype of the common native wildflower Castilleja hispida with the endangered wildflower C. levisecta has resulted in putative Castilleja hybrids on restoration sites, prompting fears that genetic...
Lycopodium alkaloids have shown widespread and noteworthy biological activity, consisting of over 250 known natural products. Moreover, their structural complexity and diversity have attracted considerable attention from numerous laboratories including our own. Recently, we have developed a unified approach that would provides access to numerous, previously unprepared C₁₀-functionalized lycopodium alkaloids....
The increasing knowledge of the significance of vitamin B₆ in
human metabolic processes has emphasized the importance of developing
reliable means of assessing nutritional status with respect to
this vitamin. One possible approach to this end is the measurement
of pyridoxal phosphate in blood or plasma, particularly since this
phosphorylated...
Two novel and highly related C₂H₂ zinc finger proteins (CTIP1/BCL11A/EVI9 and CTIP2/BCL11B/Rit1) have been implicated in COUP-TF signaling, etiology of myeloid and lymphoid malignancies, and hematopoietic cell development. However, the precise cellular function(s) and the contribution of these proteins to neoplastic processes and hematopoietic cell development remain unknown. The goal...
This thesis describes the development of a new enantioselective synthetic method employing chiral cis-2,5-diaminobicyclo[2.2.2]octane-based organometallic catalysts. The significance of this new method to organic synthesis is illustrated with preparation of enantioenriched products that are transformed to important pharmaceutical agents. Chapter 1 provides a brief historical overview of asymmetric catalysis, especially...
To determine if 6 weeks prior supplementation with vitamins E and C
