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...

Nuclear Dipolar Relaxation in Pure Solids

Relaxat ion o f the nuclear dipolar energy ( J ^ u / is considered. The static part o f J^D sets up an energy reservoir, and its dynamic part is taken as the predominant cause for the spinlattice relaxation. This situation m a y be realized in nature in such pure solids in which molecular reorientations are frequent. Relaxation steps in which the total nuclear spin quantum number does no t chan...

Theory of nuclear magnetic relaxation in Haldane-gap antiferromagnets.

A Theory of Nuclear Magnetic Resonance (NMR) is developed for integerspin, one-dimensional antiferromagnets, which exhibit the Haldane gap. We consider free boson, free fermion and non-linear σ-model approaches, all of which give similar results. Detailed anisotropy and magnetic field dependence is calculated and compared with experiment. 75.10 Jm Typeset using REVTEX 1

Nuclear Magnetic Relaxation

High-resolution nuclear magnetic resonance of solids.

The development of line-narrowing techniques, such as magic-angle spinning (MAS) and high-power decoupling, has led to powerful high-resolution nuclear magnetic resonance approaches for solid samples. In favorable cases (for instance, where high abundances of protons are present) cross polarization (CP) provides a means of circumventing the time bottleneck caused by inefficient spinlattice rela...
