    The last years were marked by a growing interest in the problems of people of the elderly age. The reason for this was the phenomenon of the aging of the world’s population. In implementing the concept of Β«healthy or the benefits of agingΒ», considered by UN experts as one of the main directions of the Β«Program of Scientific Research work of the problems of Aging in the 21st CenturyΒ», great importance is attached to changing a person’s life (refuse of bad habits, the time of beginning of sexual activity, dietary habits and others), which can prove to be very effective not only in increasing life expectancy, but also in improving its quality. For medical care. This article provides information about the health condition of elderly women in the foothill areas of Dagestan, using the example of the Akushinsky district for identifying priorities for older women and developing proposals for executive bodies, which was the purpose of this study.ПослСдниС Π³ΠΎΠ΄Ρ‹ ознамСновались усилСниСм интСрСса ΠΊ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΠ°ΠΌ людСй ΠΏΠΎΠΆΠΈΠ»ΠΎΠ³ΠΎ ΠΈ старчСского возраста.

    Development of singularities for the compressible Euler equations with external force in several dimensions

    Full text link
    We consider solutions to the Euler equations in the whole space from a certain class, which can be characterized, in particular, by finiteness of mass, total energy and momentum. We prove that for a large class of right-hand sides, including the viscous term, such solutions, no matter how smooth initially, develop a singularity within a finite time. We find a sufficient condition for the singularity formation, "the best sufficient condition", in the sense that one can explicitly construct a global in time smooth solution for which this condition is not satisfied "arbitrary little". Also compactly supported perturbation of nontrivial constant state is considered. We generalize the known theorem by Sideris on initial data resulting in singularities. Finally, we investigate the influence of frictional damping and rotation on the singularity formation.Comment: 23 page

    Sonochemically-Produced Metal-Containing Polydopamine Nanoparticles and Their Antibacterial and Antibiofilm Activity

    No full text
    A facile one-pot sonochemical synthesis of Cu-, Ag-, and hybrid Cu/Ag-based polydopamine nanoparticles (Cu-, Ag-, and Cu/Ag-PDA-NPs) and the mechanisms by which they exert antibacterial and antibiofilm activities are reported. We showed that the nanoparticles are spherical with a core–shell structure. Whereas Cu is chelated to the shell of Cu-PDA-NPs in oxidation states of +1/+2, the core of Ag-PDA-NPs is filled with elemental AgΒ°. Sonochemical irradiation of dopamine in the presence of both Cu<sup>2+</sup> and Ag<sup>+</sup> generates hybrid Cu/Ag-PDA-NPs, whose shells are composed of Cu-chelated PDA with AgΒ° in the core. The redox potential of the metals was found to be the main determinant of the location and oxidation state of the metals. Leaching studies under physiological conditions reveal a relatively fast release of Cu ions from the shell, whereas Ag leaches very slowly from the core. The metal-containing PDA-NPs are highly microbicidal and exhibit potent antibiofilm activity. The combination of both metals in Cu/Ag-PDA-NPs is especially effective against bacteria and robust biofilms, owing to the dual bactericidal mechanisms of the metals. Most importantly, both Ag- and Cu/Ag-PDA-NPs proved to be significantly more antibacterial than commercial Ag-NPs while exhibiting lower toxicity toward NIH 3T3 mouse embryonic fibroblasts. Mechanistically, the metal-containing PDA-NPs generate stable PDA-semiquinone and reactive oxygen species under physiological conditions, which contribute at least partly to the antimicrobial activity. We also demonstrated that simple treatment of surfaces with Ag-PDA-NPs converts them to antibacterial, the activity of which was preserved even after prolonged storage under ambient conditions
