Statistical clumped isotope signatures
High precision measurements of molecules containing more than one heavy isotope may provide novel constraints on element cycles in nature. These so-called clumped isotope signatures are reported relative to the random (stochastic) distribution of heavy isotopes over all available isotopocules of a molecule, which is the conventional reference. When multiple indistinguishable atoms of the same e...
متن کاملTriple oxygen isotope variations in sedimentary rocks
Relatively large (P0.2&) O anomalies in the geologic record have been used to recognize atmospheric processes such as photochemical reactions and to trace changes in the partial pressures of O2 and CO2 in Earth’s atmosphere through time. However, recent oxygen isotope measurements of terrestrial rocks, minerals and waters also reveal common, smaller (but statistically significant) deviations fr...
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 اولHerbivore tooth oxygen isotope compositions: Effects of diet and physiology
-The applicability of rapid and precise laser probe analysis of tooth enamel for 6 ~O has been verified, and the method has been applied to different modern herbivores in East Africa. Sampling and pretreatment procedures involve initial bleaching and grinding of enamel to <75 /~m, and elimination of adsorbed water and organic compounds with BrFs. Typical analytical reproducibilities for 0 .5-2 ...
متن کاملOxygen- and Mg-isotope Compositions of Cais from Rumuruti
Introduction: We have recently characterized the mineralogy and petrography of ~ 100 CAIs from ~20 R chondrites [1]. Here we report O-isotope compositions of ten R CAIs and Mg-isotope composition of three hibonite-bearing CAIs: H030
