Growing demand for limited quantities of fish has led to systematic
planning for the conservation and management of U.S. fishery resources.
There is a need for better understanding of the complex biological and
social environment on which regulation for conservation, social, and
economic purposes is imposed. The behavior of commercial...
The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...
Literary fairy tales facilitate a specific inquiry into heroine quests. Due to the flexibility of the fairy tale genre, a variety of heroine tales have been produced. The specific stages of a heroine quest must be described in order to understand the direction and goals of these quests. In order...
This work consolidates from many sources features of the fresh frozen shrimp industry in terms of its product volume, value, growth trends and position relative to other Oregon seafood commodities. Market structure and functions are described as the product moves from the fisherman through the processor, broker, wholesaler and retailer...
In western Oregon the titratable acidity of grapes at
harvest may in some seasons be higher than desirable for
making quality wine, due to the retention of malic acid.
The purposes of this study were 1) to investigate the
effects of a vineyard cultural practice, cluster exposure
at veraison by...
The enantioselective total synthesis of quinolizidine-containing natural product cermizine D and formal syntheses of senepodine G and cermizine C has been achieved. These natural products are members of the lycopodium alkaloids, which have attracted significant attention due to their exciting biological activities and the diverse structural scaffolds. Key steps in...
Azaspiracid-1, a novel marine toxin that contains 9 rings and 20 stereogenic centers, has drawn considerable attention from synthetic groups worldwide due to its structural complexity, which includes a unique trioxabisspiroketal fused to a tetrahydrofuran ring (ABCD rings), a piperidine-tetrahydrofuran spiroaminal system fused to a 2,9-dioxabicyclo[3.3.1]nonane system (FGHI rings), a...
As the future electrical power systems tend towards smarter and greener technology, thedeployment of self-sufficient networks, or microgrids, becomes more likely. Microgridsmay operate on their own or synchronized with the main grid, thus control methodsneed to take into account islanding and reconnecting said networks. Isolation of subnetworks may be necessary...
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.
