Theory and observation of double discontinuities
Recent research using high-resolution magnetic field data to examine the interior structures of MHD shocks in interplanetary space and in the magnetotail led to a surprising discovery that a slow-mode shock is often followed by an adjoining rotational discontinuity layer on the postshock side. The thickness of each layer is of the order of a few ion inertial lengths. Such a compound structure i...
متن کاملDo double ‘SS precursors’ mean double discontinuities?
S U M M A R Y Stacks of SS precursors have been widely used in the past two decades to investigate the existence and characteristics of upper mantle discontinuities on a global scale as well as in several regional cases. Here, we present observations of SS precursors from an Mb 6.7 earthquake recorded at the US Transportable Array in 2010. In this particular case, the S660S precursors on the tr...

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 اولThe theory of observation Logico-historical philosophy of as a transformative theory of sciences
Innovation and evolution in sciences needs to its own logical methodology. This paper, considering the necessity of evolution in sciences, has intended to establish a theory called the theory of observation. It would be counted as a model for the philosophies of with a logico-historical approach. Following the purpose, the author has explained technical terms such as research method, theory,...
متن کامل33 Do ” double SS precursors ” mean double discontinuities ?
SS precursors are the underside reflections from the upper mantle discontinuities such as those at 410 and 660 km. They are important tools for studying the existence and characteristics of mantle discontinuities both on the global and regional scales (see Deuss, 2009 for a review). Due to their sensitivity at the midpoint between source and receiver, coverage for oceanic regions is achieved wh...
