| 1 | Radioprotective thermally generated free-radical dextrins显示文摘Effect of doses of the X-ray radiation from 0 to 400 Gy upon granular cornstarch and dextrins (British gums, BG) thermally generated from it at 230-300℃ was recognized with quantitative EPR and IR ab-sorption spectroscopy, molecular mass distribution in the depolymerization products, Scanning Elec-tron Microscopy, and X-ray diffractometry. Fractal analysis of the profiles of molecular mass distribu-tion showed that the depolymerization involved debranching of amylopectin. Roasting of cornstarch produced BG which differed in concentration and EPR parameters of stable free radicals from BG generated by X-ray radiation. Two types of stable free radicals, with Gaussian and Lorentzian shapes of EPR signals, were recognized. The shapes of the signals and temperature dependence on free radical intensity indicated exchanging interactions of the antiferromagnetic type, causing partial quenching of the spins at-196℃ (77K). Upon X-ray irradiation, new radicals were generated, the number and stability of which strongly depended on the types of radicals present before irradiation. These radicals slowly ceased because of a repolymerization of BG on storage. | Piotr TOMASIK Oskar MICHALSKI Ewa BIDZINSKA Antonina CEBULSKA-WASILEWSKA Krystyna DYREK Maciej FIEDOROWICZ Pawe OLKO | 2008 | Chinese Science Bulletin2008，53，7： | 3 |

| 15 | ON AN EQUATION CHARACTERIZING MULTI-CAUCHY-JENSEN MAPPINGS AND ITS HYERS-ULAM STABILITY显示文摘In this paper,we give two characterizations of multi-Cauchy-Jensen mappings.One of them reduces the system of n equations defining these mappings to a single functional equation.We also prove,using the fixed point method,the generalized Hyers-Ulam stability of this equation.Our results generalize some known outcomes. | Anna BAHYRYCZ Krzysztof CIEPLINSKI Jolanta OLKO | 2015 | Acta Mathematica Scientia2015，35，6： | 0 |
| 16 | Radioprotectors from pyrodextrins显示文摘Cornstarch heated in the range of 230-280°C depolymerized into pyrodextrins characterized by two-component EPR signals of relatively stable free radicals.These thermally generated radicals could serve as efficient scavengers for free radicals generated from pyrodextrins with the 200 Gy dose of γ-radiation.The most efficient traps/scavengers were produced from cornstarch at 250-280°C.IR data indicated incorporation of the OH groups to the pyrodextrins.These groups most probably originated from the OH· radicals formed by the radiolysis of water.EPR spectra provided evidence for trapping free radicals generated by γ-irradiation and for their subsequent annihilation on contact with pyrodextrins.Water affected radical processes occurring in pyrodextrins caused by γ-irradiation. | MICHALSKI Oskar BIDZINSKA Ewa BOROWSKI Micha DYREK Krystyna OLKO Pawe STOLARCZYK Liliana SWAKON Jan TOMASIK Piotr WENDA ElZbieta | 2010 | Chinese Science Bulletin2010，55，31： | 0 |
