On a finite group having a normal series whose factors have bicyclic Sylow subgroups
(Taylor & Francis Group, 2011)We consider the structure of a finite group having a normal series whose factors have bicyclic Sylow subgroups. In particular, we investigate groups of odd order and A4-free groups with this property. Exact estimations ...2020-11-10 -
On Boundary Value Problems for First-Order Elliptic Pseudosymmetric Systems in R^4
(Differential Equations, 2003)It is proved that there are no regularizing boundary-value problem for pseudo-symmetric elliptic systems of four equations of the first order in R^4.2020-11-10 -
On groups with biprimary subgroups of even order
(2017)We investigate groups in which maximal subgroups of even order are primary or biprimary. We also research soluble groups with restriction on a number of prime devisors of some proper subgroup orders. We give applications ...2020-11-10 -
On groups with formational subnormal Sylow subgroups
(De Gruyter, 2018)We investigate a finite group G with F-subnormal Sylow subgroups, where F is a subgroup-closed formation and A1A⊆F⊆NA. We prove that G is soluble and the derived subgroup of each metanilpotent subgroup is nilpotent. We ...2020-09-18 -
On the residual of a finite group with semi-subnormal subgroups
(2020)A subgroup A of a group G is called seminormal in G, if there exists a subgroup B such that G = AB and AX is a subgroup of G for every subgroup X of B. We introduce the new concept that unites subnormality and seminormality. A ...2020-11-10 -
Oт maximal subgroup of a finite solvable subgroup
(EURASIAN MATHEMATICAL JOURNAL, 2012)Let H be a non-normal maximal subgroup of a finite solvable group G, and let q ∈ π(F (H/CoreGH)). It is proved that G has a Sylow q-subgroup Q such that NG(Q) ⊆ H.2020-11-12 -
Phytomanagement and Remediation of Cu-Contaminated Soils by High Yielding Crops at a Former Wood Preservation Site: Sunflower Biomass and Ionome
(Frontiers Media, 2018-09-04)This long-term field trial aimed at remediating a Cu-contaminated soil to promote crop production and soil functions at a former wood preservation site. Twenty-eight field plots with total topsoil Cu in the 198–1,169 mg ...2020-09-16 -
POST-NON-CLASSICAL PEDAGOGICAL RESEARCH STRATEGIES
(European Proceedings of Social and Behavioural Sciences EpSBS, 2020)The article reveals the essence of the concept “methodological strategy of pedagogical research”, focuses attention on the potential of polyparadigmin pedagogical research, the alternative of scientific ideals, methodological ...2020-09-25 -
Predicted model of magnetocaloric effect in BiFeO3-based multiferroics.
(Elsevier B.V, 2019-06-20)Structure, magnetic properties and magnetocaloric effect in synthesized Bi-based multiferroics with a partial isovalent substitution of bismuth (III) cations for rare-earth elements (R = La, Nd, Sm, Eu, Gd, Dy, Er) have ...2021-12-22 -

Regularization of ill-posed problems in Hilbert space by means of the implicit iteration process
(Київський нацiональний унiверситет iменi Тараса Шевченка, 2015)The article substantiates the convergence of the method with a posteriori choice of the number of iterations in the original norm of Hilbert space in case of a self-adjoint operator on the assumption of existing errors in ...2020-09-18 -
Revised limit of the Saalian ice sheet in central Europe
(2018)Geological investigations in the southern part of the Polish-Belarusian cross-border area were focused on correlation of main Middle Pleistocene stratigraphic units and on extent of the ice sheet of the Saalian Glaciation. ...2020-12-14 -
Right-Side Hyperbolic Operators
(State University of Novi Pazar, 2014)In the paper a new class of linear operators was introduced: linear operator B is said to be right-side hyperbolic, if operators B−l I are right-sided invertible for any l from a neighborhood of the unit circle and moreover ...2020-09-17 -

Solvable groups with restrictions on Sylow subgroups of the Fitting subgroup
(World Scientific Publishing Company, 2016)In this paper, we study solvable groups in which rn(F) is at most 2. In particular, we investigated groups of odd order and A4-free groups with this property. Exact estimations of the derived length and nilpotent length ...2020-11-10 -
Some approaches to the calculation of the normalized Mott cross section, displacement cross section, and the Mott correction to the Bethe formula
(ELSEVIER, 2022)A new exact representation for the normalized Mott cross section is obtained. Some earlier exact and approximate methods for its calculation are compared with the method proposed in this work. It is demonstrated that applying ...2021-12-08 -
