Interaction of the dispersed phase of the fullerene C
60 hydrosol with cationic dyes, Indopolycarbocyanines, Methylene Blue and others, results in the adsorption of the dyes on the surface of ...colloidal particles. The phenomenon is accompanied by expressed changes in the absorption spectra of all the dyes, as well as in fluorescence quenching in the case of Indotricarbocyanine, and leads to the coagulation of the sol. The structural forces, caused by hydrophobization of the fullerene–water interface, play a decisive role in the coagulation phenomena.

The objective: to characterize tuberculosis in children exposed todrug-resistant tuberculosis in St. Petersburg.Subjects and methods. 51 children exposed to tuberculosis in their families were ...enrolled into the study; of them, 23 children were exposed to MDR TB; 7 children were exposed to other drug resistant patterns of the disease; 21 children were exposed to drug susceptible tuberculosis.Results. In St. Petersburg in 2015-2017, MDR TB cases prevailed among adult index cases to whom children were exposed. The course of tuberculosis was the most severe in children exposed to MDR TB. Such children were treated with regimen IV with high efficacy achieved, taking into account the severity of the disease, age, concurrent disorders, and tolerability of the drugs, as well as drug resistance of the index case.
The Spin Supercurrent and Bose-Einstein condensation of magnons, similar to an atomic BEC, was observed in 1984 in superfluid super(3)He-B. The same phenomena should exist in solid magnetic systems. ...We describe here the first observation of magnon BEC in solid easy plain antiferromagnets CsMnF sub(3) and MnC0 sub(3). We have observed magnon BEC on a mode of coupled Nuclear-Electron precession. The dynamical properties of this mode have many similarities with NMR of superfluid super(3)He-A. The frequency changes with deflection of nuclear magnetization. Furthermore, the involvement of electron ordered subsystem gives the magnon-magnon interaction, spin waves and spin supercurrent, while the nuclear subsystem gives the relatively long time of relaxation.
In the face of the scientific-technological revolution and the competition of the two social and economic systems, bourgeois economists are forced to devote much attention to the study of the role of ...man and live labor in social production. Bourgeois economic science is researching the economic significance of the qualitative state of the work force (its educational and skill level, mobility, etc.) within the framework of the theory of so-called human capital. This conception is one of the varieties of the bourgeois theories of the "transformation" of capitalism in which the working class is counted among the owners of "human" capital.

This paper presents the mathematical model constructed to estimate the achievable minimum of freight transportation cost with time constraints, including the intervals between flights. The model ...allows to compare alternative types of transport, optimizing the vehicles load capacity and the road network connectivity. The areas of unmanned aerial vehicles preferred application are identified.
Measurements of multiplicity fluctuations of identified hadrons produced in inelastic p+p interactions at 31, 40, 80, and 158~\GeVc beam momentum are presented. Three different measures of ...multiplicity fluctuations are used: the scaled variance \(\omega\) and strongly intensive measures \(\Sigma\) and \(\Delta\). These fluctuation measures involve second and first moments of joint multiplicity distributions. Data analysis is performed using the Identity method which corrects for incomplete particle identification. Strongly intensive quantities are calculated in order to allow for a direct comparison to corresponding results on nucleus-nucleus collisions. The results for different hadron types are shown as a function of collision energy. A comparison with predictions of string-resonance Monte-Carlo models: Epos, Smash and Venus, is also presented.
