On the modularity of the lattice of Baer-σ-local formations
Autor: N. N. Vorob’ev
Publikováno v: Proceedings of the National Academy of Sciences of Belarus. Physics and Mathematics Series. 59:7-17
Throughout this paper, all groups are finite. A group class closed under taking homomorphic images and finite subdirect products is called a formation. The symbol σ denotes some partition of the set of all primes. V. G. Safonov, I. N. Safonova, A. N

Publikováno v: Siberian Mathematical Journal. 62:586-597
Let $ n>0 $ and let $ \sigma=\{\sigma_{i}\mid i\in I\} $ be a partition of the set of all primes $ {𝕇} $ . We prove that the lattice of all $ n $ -multiply $ \sigma $ -local formations is inductive and $ {\mathfrak{G}} $ -separated.

COMPUTATIONAL AND EXPERIMENTAL STUDY OF THE EFFECTIVE THERMAL CONDUCTIVITY OF FIBROUS MATERIALS
Autor: N. N. Vorob’ev, A.V. Zuev, S.I. Pakhomkin, D.Ya. Barinov
Publikováno v: Proceedings of VIAM. :95-102
The article is devoted to the evaluation of the effect of porosity on the effective thermal conductivity of thermal insulation materials. The main factors influencing the thermal conductivity of the material, such as density, the type of porous struc

Evaluation of the Variability of Glass Transition Temperature of Carbon-Fiber-Reinforced Plastic Fabricated by Autoclave Molding
Autor: N. N. Vorob’ev, A. N. Vasyukov, O. G. Ospennikova, P. S. Marakhovskii, S. Yu. Shorstov, D.Ya. Barinov
Publikováno v: Polymer Science, Series D. 13:73-79
In this work, temperature fields have been modeled during autoclave molding of VKU-46 carbon-fiber-reinforced plastic. It has been shown that a degree of conversion of 97.2–98.4% is achieved in the center of plate upon curing according to the chose

On Complete Sublattices of Formations of Finite Groups
Autor: N. N. Vorob’ev
Publikováno v: Russian Mathematics. 62:17-22
We prove that the lattice of all τ-closed saturated formations of finite groups is a complete sublattice of the lattice of all τ-closed solubly saturated formations of finite groups.
