Analysis of Relaxation Times of Radicals in Irradiated Black Pepper Using Pulse-ESR and CW-ESR

Pros and Cons of Pulse Dipolar Esr:

ESR spin trapping of hydroxyl radicals in aqueous solution irradiated with high-LET carbon-ion beams.

The aim of this study was to quantify the hydroxyl radicals (*OH) produced when aqueous solutions are decomposed by high-linear energy transfer (LET) 290 MeV/nucleon carbon-ion beams using an electron spin resonance (ESR) spectrometer. Aerated cell culture medium containing 200 mM 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) was irradiated with doses of 0 to 20 Gy with an LET of 20 to 90 keV/ micro ...

Electron Spin Resonance (ESR) studies on radical scavenging activity of gamma ray irradiated pepper

The properties of radicals induced in the gamma ray irradiated pepper were investigated by means of spin trapping method and CW-ESR spectroscopy. Three radicals were found in the specimens irrespective of irradiation. The representative ESR spectrum of pepper is composed of a sextet centered at g = 2.0, a singlet at the same g-value, and a singlet at g = 4.0. The first signal is attributable to...

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...
