Monitoring the temperature and humidity of the air in the premises of granaries and in containers with grain allows you to create automatic systems to maintain the storage conditions of grain, which is necessary to preserve its grade. This article proposes a system for wireless monitoring of temperature and humidity, reducing the cost of laying and operating cable thermometers in the infrastructure of the storage facilities, monitoring the temperature and humidity of air at different levels of grain mounds, and monitoring the temperature and moisture of the spent drying agent in silage.

The article deals with the problem of creating a system for conducting public accreditation of educational programs in educational organizations of the law enforcement system. The authors formulated proposals on the use of evaluation by independent associations of experts and representatives of the employer when conducting professional public accreditation in the educational organizations of the law enforcement system, taking into account its specific characteristics and conditions of a particular environment. With the participation of the authors, within the framework of the Comprehensive Plan for the Scientific Support of Activities for 2018, a study was conducted to substantiate and provide methodological support for conducting professional public accreditation of educational programs in educational organizations of the law enforcement system. The expected results of the introduction of the institute of professional and public accreditation in the departmental educational organizations are considered: improving the quality of educational programs implemented, the level of organization of staff training, the quality and relevance of educational services, and the image of departmental service.

Using laser ablation, nanoparticles of Sc, Ti, V, Cr, Mn, Fe, Co, Ni with controlled sizes and properties were obtained. To obtain nanoparticles of a given size, not only ablation of massive targets was used, but fragmentation (exposure to a mixture of micro- and nanoparticles by laser radiation). The evolution of the particle size distribution function in the process of their laser fragmentation is investigated and its key parameters determining it are established, such as the energy density of a laser beam in a medium and the peak power of laser radiation. Different schemes for introducing laser radiation into colloidal systems have been used. To obtain nanoparticles that do not contain oxide films, organic alcohols (ethanol and propanol-2) were used as the working fluid. The obtained nanoparticles met the following criteria: 1). at least 95% of the particles in the preparation have the specified diameter; 2). The shape of the nanoparticles is close to spherical; 3). The composition of the nanoparticles does not include a significant amount of impurities and oxides; 4). In most of the nanoparticles, a metal crystal lattice is observed, although under certain conditions it is possible to obtain nanoparticles, both with the outer oxide layer and entirely consisting of oxides. The stability of the obtained colloid nanoparticles was investigated. It is assumed that the solvent is saturated with molecular hydrogen to prevent oxidation of nanoparticles during storage.
