Temporal nature of plasticity in the design of materials

A full spectrum of materials responses to dynamic loading and observed temporal effects of plasticity from a united viewpoint are analyzed. The relaxation model of plasticity with characteristic time idea is capable to effectively predict the instability of the stress-strain dependencies on strain rates. It is shown that empirical models cannot simultaneously simulate the appearance and disappearance of the yield drop unlike the relaxation model of plasticity presented in the paper

STUDYING OF DRYING CONDITION IMPACT ON GINSENG TISSUE CULTURE BIOMASS QUALITY INDICATOR

At the moment the task of obtaining high-efficient plant medicinal with wide range of action to be used for pharmaceutical, cosmetic, food industry as a biologically active additives remains valid. The ginseng tissue culture drying parameters impact on the biomass quality (chemistry of biologically active substances and antioxidant activity) is studied in this article. It was identified that increasing temperature and decrease the drying time of ginseng tissue increases antioxidant activity. Qualitative and quantitative analyses confirmed authenticity of the biomass compared to the control (ginseng root tincture)
