The porosities of ordinary chondrites: Models and interpretation

Densities and Porosities of Ordinary Chondrites; Do High Porosity Meteorites Represent Regolith Materials?

Introduction: Densities and porosities of meteorites provide information about the physical properties of their parent bodies (asteroids). Recent studies report the densities and porosities of ~40 ordinary chondrite (OC) meteorites [1,2]. In this study, we present 42 additional measurements of OC densities and porosities, and provide a rigorous analysis of the errors in the method. Additionally...

Oxygen isotopes in R-chondrite magnetite and olivine: Links between R chondrites and ordinary chondrites

Ion-microprobe studies yield DO (5dO 2 0.52 z dO) values in magnetite from the Rumurti chondrite (RC) PCA91241 (which is paired with PCA91002) of 13.1 to 13.9‰, slightly higher than that in O from whole-rock R samples. Despite DO values in whole-rock RCs that are much (by ca. 1.6‰) higher than in whole-rock LL chondrites, the DO in R magnetite is much lower (by ca. 2‰) than the values (14 to 17...

Be-B IN ENSTATITE AND ORDINARY CHONDRITES: A PRELIMINARY STUDY

the 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...
