Features of the reproductive history and health status of elderly women in the mountains districts of the Republic of Dagestan
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 worldβs 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 personβs 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.ΠΠΎΡΠ»Π΅Π΄Π½ΠΈΠ΅ Π³ΠΎΠ΄Ρ ΠΎΠ·Π½Π°ΠΌΠ΅Π½ΠΎΠ²Π°Π»ΠΈΡΡ ΡΡΠΈΠ»Π΅Π½ΠΈΠ΅ΠΌ ΠΈΠ½ΡΠ΅ΡΠ΅ΡΠ° ΠΊ ΠΏΡΠΎΠ±Π»Π΅ΠΌΠ°ΠΌ Π»ΡΠ΄Π΅ΠΉ ΠΏΠΎΠΆΠΈΠ»ΠΎΠ³ΠΎ ΠΈ ΡΡΠ°ΡΡΠ΅ΡΠΊΠΎΠ³ΠΎ Π²ΠΎΠ·ΡΠ°ΡΡΠ°.

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