An estimate for the Dirichlet series in a half-strip in the case of the irregular distribution of exponents. II

We study the Dirichlet series that are convergent only in a half-plane and whose sequence of exponents extends to a “regular” sequence. We establish some unimprovable estimates for the order of the sum of the Dirichlet series in a half-strip whose width depends on the special distribution density of the exponents.     

Effect of dispersity and drying mode of silica on deformation-strength properties of latex films

Effect of dispersity, content, and nature of silica on the deformation-strength parameters of latex films obtained under various conditions was studied.     

Evolution of the ice breaking process

The spatial problem of the stress-strain state of an ice sheet of finite thickness broken by a patented method is solved using the theory of small elastic strains and a proven numerical method. __________ Translated from Prikladnaya Mekhanika i Tekhnicheskaya Fizika, Vol. 49, No. 1, pp. 114–119, January–February, 2008.
