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...

Study of point defects in CdTe and CdTe:V by cathodoluminescence

The defect structure of CdTe substrates has often been investigated with luminescence techniques. In particular, a luminescence band normally referred as the 1.40 eV band, has been associated with recombination processes involving defects but its nature seems to be complex. Myers et al.’ in their photoluminescence study of CdTe wafers concluded that a significant part of the 1.40 eV band is dir...

Cathodoluminescence and photoinduced current spectroscopy studies of defects in Cd0.8Zn0.2Te.

Deep levels in Cd12xZn xTe have not yet been fully characterized and understood, even though this material is very promising for medical and optoelectronic applications. We have investigated p-type semi-insulating Cd0.8Zn0.2Te with cathodoluminescence ~CL! and photoinduced current transient spectroscopy ~PICTS! methods. PICTS analyses allow detection of deep levels which are not revealed by oth...

Intrinsic Defects in Semiconductors

In all previous consideration of crystal structure and crystal growth, for simplicity it has been assumed that the silicon crystal lattice is entirely free of defects. Of course, in reality, this cannot be true since at any temperature greater than absolute zero, no crystal of finite size can be absolutely perfect. Indeed, there are a number of different types of defects that can exist within t...
