Some processes of irrational rationalization and two-sided evaluation of a single number series
Annotation: In this article we consider some fractional-irrational expressions and prove the assertion that reduce them to fractional-rational expressions and also consider one general lower-and-upper bound (two-sided estimate) for one numerical series.

Graphite laminated materials strength properties and energy characteristics of polymer binders
Annotation: The approach which was proposed earlier for composite materials strength prediction using contact angle measurements was applied for graphite laminated materials. It was shown that the calculation of the work of adhesion to polar and non-polar model liquids can be applied to the choice of polymer binder.
