Dispersion properties of a viscoelastic layer and a thin-walled hollow circular cylinder are studied by asymptotic methods. The viscoelastic properties of the material are described by the constitutive equations in the integral form with the fractional exponential Rabotnov's function as a kernel of the integral operators. For both types of waveguides, the generalized power series expansion are used...
After stress (immobilization in cages) plasma corticosterone level in prematurely aging OXYS rats was higher, while the content of NO metabolites was much lower than in Wistar rats. Stress increased blood pressure in OXYS and Wistar rats, the maximum values were observed in control and stressed OXYS rats. The concentration of reduced glutathione in the brain of OXYS rats was lower than in Wistar rats...
