Chitin and chitosan with degree of deacetylation (DD) 57, 85, 89, and 90% were obtained as 250-μm microparticles. Their behavior with shear flow in aqueous and acidic solutions was studied. It was found that chitosan microparticles with various DD converted into gels as a result of swelling in water. Chitosan hydrogel particles with DD >85% were destroyed in shear flow without destroying the chains. The macromolecules were ordered in the direction of the flow. © 2016 Springer Science+Business Media New York Source

We study the pursuit-evasion problem for a model game with simple motions when pursuer controls are subject to both integral and geometric constraints while evader controls are only subject to geometric ones. Depending on initial conditions of the players and parametric values participating in control constraints, we prove the theorem of alternative. To solve the pursuit problem, we propose a parallel pursuit strategy (Π-strategy) that ensures optimal convergence of the players and study its structure depending on the parameters. To solve the evasion problem, we find lower bounds on the convergence that also depend on given parameters. This work develops and extends the works of Isaacs, Petrosyan, Pshenichnyi and other researchers, including the author. © 2013 Pleiades Publishing, Ltd. Source

The paper studies problems of group pursuit for differential games with integral constraints imposed on the controls of players such as the Pontryagin control example and a group pursuit with a simple motion for the case of l-catch. The problems are solved on the basis of Chikrii's method of resolving functions. A structure to construct the resolving function is proposed, which substantiates the parallel approach strategy, i.e., the Π-strategy for pursuers. New sufficient solvability conditions for problems of group pursuit are obtained. © 2013 Springer Science+Business Media New York. Source

The paper studies problems of group pursuit for linear differential games with integral constraints. The problems are analyzed on the basis of Chikrii's method of resolving functions. The proposed method substantiates the parallel approach strategy, i.e., the Π-strategy. The new sufficient solvability conditions are obtained for problems of group pursuit. As an example, two classes of problems are considered, namely, the Pontryagin control example and a group pursuit with a simple motion for the case of "l-catch." © 2013 Springer Science+Business Media New York.

We study the Potts model on the Cayley tree. We demonstrate that for this model with a zero external field, periodic Gibbs measures on some invariant sets are translation invariant. Furthermore, we find the conditions under which the Potts model with a nonzero external field admits periodic Gibbs measures. © 2013 Pleiades Publishing, Ltd. Source
