The seafood sector has been followed and presented through different data collected as for example by FAO over several years. Often these studies are globally and/or macro-oriented market and even though these studies clearly add insight and understanding they do not provide the details needed for assessing the different sectors...
Farmed fish products in Europe are mainly addressed to the market of live and fresh whole fishes. Only for the trout sector, due to their vertical integration, is it common to process/transform the fish, offering a wider range of products to final consumers. One key factor that makes the supply...
Based on financial risk analysis and portfolio theory, this paper aims to estimate the underlying risk of the European fish quota distribution among European member States along the time. Firstly, we have assigned a fishing portfolio to each member state (FP(jt)) and its related value based financial portfolio (FPV(ijt)), where...
A cultural landscape analysis of two historic cemeteries in St. Paul, Oregon demonstrates that the residents of this early community were unknowingly using grave markers to express their worldview and the identities that they felt were most important. Because of the historical and cultural development of this community as the...
In the early part of his philosophical career, Paul Ricoeur worked out a general theory of symbols which he illustrated with the symbols of evil. He subsequently explained this theory in several essays (his final major statement on symbols can be found in Interpretation Theory: Discourse and the Surplus of...

Unfortunately, the work they so...
The Amsterdam-St. Paul Plateau is bisected by the intermediate-rate spreading Southeast Indian Ridge, and numerous geophysical and tectonic anomalies arise from the interactions of the Amsterdam-St. Paul hotspot and the spreading center. The plate boundary geometry on the hotspot platform evolves rapidly (on timescales <1 Myr), off-axis volcanism is abundant,...
This thesis traces the relationship between the First World War, constructions of masculinity, and the life and poetry of T.S. Eliot. Central to this relationship is a study of homoeroticism, which the author characterizes as different from homosexuality but not exclusive of it, in late 19th and early 20th century...
During his lifetime C. S. Lewis chose to speak to Christians in plain and simple language that they could understand. Lewis taught and defended truths that he felt were discernible through reason. Morality, free will, and the divinity of Jesus Christ were fundamental to his core beliefs and teachings. His...
Unpaved roads are a critical form of infrastructure in forested landscapes but also a potential source of fine sediment that can degrade sensitive ecosystems nearby. Improved management of aggregate road surfacing can reduce sediment generation, lengthen its useful life span, reduce maintenance costs, and more importantly, mitigate the impacts of...

forest structure could be mimicked in younger stands via
overstory manipulation. Cover and species composition of
understory plants were systematically sampled in sixteen
thinned second-growth stands and sixteen adjacent unthinned
second-growth Douglas fir (Pseudotsuga menziesii (Mirabel)
Franco.) stands. The stands were thinned...
Reforesting harvested lands in southwestern Oregon has been
difficult because of low rainfall, high evaporative demand, and
competitive understory vegetation. Herbicides have been a preferred
method to control competing vegetation but herbicide use on federal
lands was curtailed in 1984. As a result, interest in livestock
grazing as a vegetation...
The ability of controlled livestock grazing, in
combination with seeding of palatable forages, to reduce
understory competition and enhance conifer
establishment, was evaluated during 1985 and 1986, on
two adjacent sites in southwestern Oregon. In 1984,
Site 1 was clearcut and broadcast burned to remove
slash, and Site 2 was...
The evaluations performed in this thesis were intended to provide a partial basis for the selection of species and varieties for reseeding Central Tunisian rangelands.

Xanthohumol [XN, (E)-6´-methoxy-3´-(3-methylbuten-2-yl)-2´,4´,4´´-trihydroxychalcone], the principal prenylated chalcone from hops, and its 2,3-dihydro- (DXN) and O6-desmethyl-2,3-dihydro- (DDXN) congeners, are of potential utility for the amelioration of metabolic syndrome; however, their complex bioactivity profiles cannot be properly studied and understood without access to appropriately produced synthetic materials.
In the first part of...
Current evidence suggests that temporal regulation of gene
expression in eucaryotic organisms relies primarily upon localized
structural modifications of chromatin. One possible means of
changing chromatin structure is through varying the level of
acetylation of the histone proteins. Sodium butyrate has been found
to inhibit the activity of histone deacetylase...
PDMS membrane-based microvalves are becoming increasingly more important for the control of fluid flow within MECS applications such as microreactors used to synthesize nanoparticles and biological macromolecules. The motivation for pursuing PDMS membrane-based microvalves is for implementing a plug flow microreactor to simulate slug flow yielding a narrower residence time...
St. Joseph's College was located within St. Paul, Oregon, the first Roman Catholic mission in the Pacific Northwest. The St. Paul mission was finally established in 1839 by Father Francois Blanchet, four years after the French-Canadian settlers in the area, appropriately known as French Prairie, had requested the presence of...
Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....
Technological advances of the last three decades have caused an enormous increase in the amount of published and unpublished information generated by our society. This inflation has created the need for improved information management systems. Existing systems are inadequate primarily because they are discipline-oriented and lack the flexibility that is...
The implicit Monte Carlo (IMC) method [16] for radiative transfer, developed in 1971, provides numerical solutions to the tightly-coupled, highly-nonlinear radiative heat transfer equations in many physical situations. Despite its popularity, there are instances of overheating in the solution for particular choices of time steps and spatial grid sizes. To...

7,7'-Dihydroxy-8,8'-biquinolyl (azaBINOL) was prepared from 7-hydroxyquinoline via N,N-dimethyl O-quinol-7-yl carbamate by directed ortho-metallation followed by FeCl₃-mediated oxidative coupling of the 8-lithioquinoline intermediate. Saponification of the resulting dicarbamate provided crystalline (±)-azaBINOL in 56% overall yield. 6,6'-Bis(dimethylaminocarbonyl)-7,7'-dihydroxy-8,8´-biquinolyl was prepared from the same dicarbamate by a double anionic-Fries rearrangement in 43% yield. 7,7'-Bis(diethylamino-carbonyloxy)-6,6'-diiodo-8,8´-biquinolyl...
This study was conducted at portions of Trap Bay Creek, a medium-sized third-order stream on Chichagof Island, Southeast Alaska, to
1) quantify short-term sediment transport and channel morphology changes, 2) relate measured sediment transport rates to the major hydrologic parameters that appeared to determine the mechanisms of sediment transport, and...
Sulfoxide-ligand exchange (SLE) and asymmetric halogen-metal exchange (AHME) processes were separately examined for the enantioselective synthesis of functionalized alpha-haloalkylmetal (carbenoid) reagents. Carbenoids derived from SLE were used to effect stereospecific reagent-controlled homologation (StReCH) of boronic esters and those generated via AHME were engaged in Darzens-type chemistry with aldehydes.
Abstract for...
The fermentation of honey-based musts has been a feature of civilization for millennia. Typically comprised of 75-90% (w/w) simple (i.e. fermentable) sugars, the glucose and fructose present are readily fermented by either pitched or adventitious micro-organisms. Nevertheless, despite its venerable heritage, honey-based fermentations are prone to inconsistency, and it is...
Sequential machines uniquely determine directed graphs. A path in a sequential machine may be specified by a starting state and an input sequence. A uniform Hamiltonian touring sequence (UHTS) is an input sequence that specifies a Hamiltonian path regardless of the starting state. We present a polynomial time algorithm that...
A graph may he drawn in many different ways. We investigate how to draw a graph nicely, in the sense of being visually pleasing. We discuss the history of this field, and look at several algorithms for drawing graphs.

The general problem of classroom scheduling is well known to be NP-complete. A typical classroom scheduling problem is that of assigning students to a limited number of pieces of laboratory equipment. Frequently several identical pieces of equipment are available only at fixed hours and have limited access due to physical...
Why are the fast Fourier transform and the fast
Hadamard transform fast? A transform can be computed by
multiplying a matrix times a vector, which normally requires 0(n²) operations. The matrices corresponding to
these transforms can be rearranged to eliminate redundant
computations resulting in O(nlogn) operations.
We investigate algebraic reasons...
Loss of wetlands within Oregon has led to strong interest in restoring wetlands that once existed. Restoration practitioners are currently using knowledge they have gained from many years of working with wetlands to design and carry out restoration projects. There is much variability between tidal wetlands within coastal
