Energy spectrum of primary cosmic rays at energies of 2 × 10<Superscript>13</Superscript> to 5 × 10<Superscript>17</Superscript> eV,according to Tien Shan data

The primary cosmic ray energy spectrum at energies of 10¹⁵ to 5 × 10¹⁷ eV is presented using the results from observations by the Tien Shan HADRON array. The spectrum was obtained from the spectrum of showers according to the number of electrons using a new way of determining the parameter of spatial distribution function S of electrons. The energy spectrum can be extended to low energies up to 2 × 10¹³ eV using data from separate experiments at the former Tien Shan array. Conclusions are drawn regarding changes in the form of the spectrum and its chemical composition at energies over 10¹⁶ eV. The spectrum is compared to the results from the TUNKA installation.

Time-temperature superposition and the relaxation flow mechanism of rubbers and rubber compounds

It is shown that there is a universal relaxation spectrum for all rubbers and rubber compounds. The relaxation spectra of different rubbers and rubber compounds differ only with respect to the extent and location of the region of existence and the absolute value of the area bounded by the curve of the spectrum in H()- coordinates.Mekhanika Polimerov, Vol. 4, No. 3, pp. 523–530, 1968
