Compacton-like solutions of the hydrodynamic system describing relaxing media
We show the existence of a compacton-like solutions within the relaxing
hydrodynamic-type model and perform numerical study of attracting features of
these solutions
Structural stability of simplest dynamical inequalities
The structural stability of families of orbits is proved for the simplest generic smooth dynamical inequality in the plane with bounded complement of the domain of complete controllability. Typical singularities of the boundaries of nonlocal transitivity zones for such inequalities are found. The stability of these singularities under small perturbations of the generic inequality is proved
On Structural Stability of Characteristic Nets and the Cauchy Problem for a TricomiβCibrario Type Equation
For a generic second-order linear partial differential equation on the plane, we discuss the problem of nonlocal normal forms and invariants of the family of its characteristics, as well as the current state of the corresponding theory. As an example of potential applications of this theory, we solve a special Cauchy problem for a mixed-type equation

The application of technological advances discussed in this article provides the opportunity to expand the indications for the use of implants of reduced diameter for further highly aesthetic prosthetics of included defects in the dentition under conditions that are initially characterized by adverse parameters. The article substantiates that the advantages of using implants of reduced diameter with included defects in the dentition, in clinical situations that, at first glance, make standard implantation with subsequent prosthetics impossible, outweigh the possible disadvantages.ΠΡΠΈΠΌΠ΅Π½Π΅Π½ΠΈΠ΅ ΡΠ΅Ρ

On the use of zirconium dioxide suprastructures, which have become widely used in the practice of aesthetic dentistry of the XXI century, the first publications appeared in 2003. Due to the mechanism of transformational hardening, this material has a unique biocompatibility and the ability to restrain the spread of microcracks under excessive loads. In this article we have conducted an extensive analysis of foreign publications devoted to the most controversial issues related to orthopedic constructions of zirconium dioxide: their biocompatibility, cytotoxicity, strength, durability.Π ΠΏΡΠΈΠΌΠ΅Π½Π΅Π½ΠΈΠΈ ΡΡΠΏΡΠ°ΡΡΡΡΠΊΡΡΡ ΠΈΠ· Π΄ΠΈΠΎΠΊΡΠΈΠ΄Π° ΡΠΈΡΠΊΠΎΠ½ΠΈΡ, ΠΊΠΎΡΠΎΡΡΠ΅ ΡΡΠ°Π»ΠΈ ΡΠΈΡΠΎΠΊΠΎ ΠΏΡΠΈΠΌΠ΅Π½ΡΡΡΡΡ Π² ΠΏΡΠ°ΠΊΡΠΈΠΊΠ΅ ΡΡΡΠ΅ΡΠΈΡΠ΅ΡΠΊΠΎΠΉ ΡΡΠΎΠΌΠ°ΡΠΎΠ»ΠΎΠ³ΠΈΠΈ XXI Π²Π΅ΠΊΠ°, ΠΏΠ΅ΡΠ²ΡΠ΅ ΠΏΡΠ±Π»ΠΈΠΊΠ°ΡΠΈΠΈ ΠΏΠΎΡΠ²ΠΈΠ»ΠΈΡΡ Π΅ΡΠ΅ Π² 2003 Π³ΠΎΠ΄Ρ.
