چکیده
Silver nanoparticles stabilized in sodium-carboxymethyl cellulose (Na-CMC) solution with degree of substitution 0,65-0.85 and polymerization 200-600 were synthesized. The structure, physico-chemical, mechanical properties bactericidal activity films obtained from solutions Na-CMC containing silver studied. shape size structure determined using atomic force microscopy UV - spectroscopy. It is established that an increase nitrate concentration film, the changed during photo irradiation. Studies have shown shape, number their biological activity. was found sizes 5-25 nm contributes to films. A basic technological scheme production technology for biodegradable contained specified dimensions bacteriostatic properties, intended treatment burns trophic ulcers, been developed.

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...

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...
