This research was on the irreversible oxidation of trimethylamine by copper(II) chloride, which takes place at temperatures of about 75° and higher. The coordination of trimethylamine by copper(II) chloride, which is a preliminary reaction to the oxidation, was studied at 0°. The coordination of trimethylamine by the potential reduction product,...
During early embryonic development, endodermal cells leave the inner cell mass (ICM) and migrate over an extracellular matrix (ECM), located on the blastocoelic side of the trophectoderm, to form a continuous layer of extraembryonic endoderm. Cell migration events depend on a family of cell surface proteins known as integrins that...
The Eastern black rail (laterallus jamaicanesis) is the smallest of the rail species and facing catastrophic decline throughout its home range. According to the U.S. Fish and Wildlife Service, the black rail population has decreased as much as 90%, leading to its proposed Federal listing as threatened under the Endangered...
With indications that fisheries production has plateued at a global capacity of 85 million metric tons in the 1990's, further exploitation of marine stocks on a sustainable basis is unrealistic. Economic development of coastal and regional economies will benefit from new approaches to maximizing benefits from harvested products that include...
The epoxide deoxygenation reaction is formally the reverse of theepoxidation reaction. Compared to epoxidation, which has reached its fullmaturity, epoxide deoxygenation has not been as intensively developed.Among the few deoxygenation reagents, a handful are catalytic in a metalcomplex, show high stereospecificity and operate under mild conditions. Acommon feature of all...
Environmental education programs seek to foster an appreciation for the natural world while introducing students to scientific thinking. Citizen science engages non-scientists in the systematic collection and analysis of data. The Betts Forest Landscape Ecology Lab combines both goals by inviting teachers in Corvallis, Oregon, and surrounding areas to participate...
The effects of freeze-drying and flake freezing of surimi on biochemical and physical properties as affected by various storage conditions were examined. Using three cooking parameters shear stress and strain values were evaluated to measure gelation properties of surimi gels. Stress values increased up to 3 months and then decreased...
Milk fever (MF), retained placenta (RP), and left displaced abomasum (LDA) are three common and costly metabolic diseases in cows during the first days of lactation. Some studies suggest that circulating concentrations of α-tocopherol (ATOC) are decreased by these three diseases. It is, however, unknown if and how long lower...
The relationship between intrinsic fish quality (fish condition before handling), production efficiency, product price, and the optimal management of commercial "wild" fisheries was explored in four companion papers. The optimal management plan-consisting of quotas and harvest schedules - would maximize the discounted net industry revenues (NPV) given a minimum biomass...
