Biochemical indicators of muscle growth in the snow crab Chionoecetes opilio (O. Fabricius).
This study examined the relationships between muscle growth rate, the activity of metabolic enzymes and the RNA:DNA ratio, in adult snow crabs Chionoecetes opilio. After moulting, crabs were assigned to three feeding rations to attain a range of tissue growth rates. Muscle growth rate, estimated by the variation in dry tissue content per ml of merus of the first walking leg, was positively corr...
متن کاملSedimentary Carbon Oxidation and Denitrification on the Shelf Break of the Alaskan Beaufort and Chukchi Seas
Sediment-water fluxes were measured on transects across the northern Alaskan continental margin. Dissolved oxygen fluxes approximated total carbon dioxide fluxes when fluxes were low, but oxygen underestimated the higher total carbon dioxide fluxes. This follows a diagenetic model in which aerobic sediments occur below 86 μmol total carbon dioxide m -2 h -1 and anaerobic conditions intensify wi...
متن کاملStorm Surges in the Beaufort and Chukchi Seas
Specific problems of storm surge modeling in the polar seas are analyzed. The vertically integrated equations of motion and continuity are applied to the prediction of the storm surge wave in both the ice-free and ice-covered seas. The interactions of atmosphere, ice, and water are expressed by the normal and tangential stresses. A numerical grid is set over the Chukchi and Beaufort seas, and t...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولA Brief and Preliminary Look at SNPs Data for some Bering-Chukchi- Beaufort Seas Bowhead Whales
We present preliminary analyses of 18 single nucleotide polymorphism markers (SNPs) for 106 bowhead whales from Barrow and St. Lawrence Island. We find no evidence for disequilibrium, population substructure, or genetic variation associated with temporal spacing of whales in the migration. Introduction We present here a preliminary examination of a small dataset of single nucleotide polymorphis...
