Objectives. The main indicator that determines electrical conductivity of rubbers is specific volumetric electrical resistance (ρv ). The purpose of this work is to investigate changes in this indicator during swelling and deswelling of electrically conductive rubbers. When considering the swelling...

The influence of morphological characteristics of carbon black on the critical shear stress in its model dispersions in dibutyl phthalate was established. The possibility of forecasting the properties of a number of rubber mixtures and rubbers by means of the critical shear stress was shown.

This article presents a detailed description of shifts in subsets of blood lymphocyte subpopulations associated with development of the corneal ulcerative lesions as well as during penetrating keratoplasty.We have revealed some general changes typical for patients with corneal ulcer and patients wit...

Herpes simplex viruses type 1 and 2 (HSV-1 and HSV-2) cause widespread lifelong infections. These characteristics of herpes simplex virus infections (HSVI) are associated with the presence of two phases in the infectious cycle: the lytic infection phase, which involves the formation of new viral par...
