A crucial prerequisite for recycling forming an integral part of municipal solid waste (MSW) management is sorting of useful materials from source-separated MSW. The morphological composition of the waste generated in Russia was studied. Theoretical bases of management of the waste sorting conveyor have been developed taking into account failures such as uneven loading and uneven sorting of waste. The calculation of the waste material balance was based on solving the system of Euler equations and flow control. Control laws are defined to control the flow and density of waste on the conveyor. A relay-contact scheme for automatic sorting of waste to extract various fractions of recyclable waste, such as metal, plastic, paper, glass and organic matter from MSW was developed. The synthesis of a finite state of a machine control system for waste sorting is implemented on a programmable logic device Omron.

In the new millennium, humanity is faced with infectious diseases that no one previously knew about. In the end of 2019, an outbreak of a new coronavirus infection occurred in the People’s Republic of China (PRC) with an epicenter in the city of Wuhan (Hubei Province). On February 11, 2020, the International Committee on the Taxonomy of Viruses assigned an official name to the infectious agent - SARS-CoV-2. According to the results of serological and phylogenetic analysis, coronaviruses are divided into four genera: Alphacoronavirus, Betacoronavirus, Gammacoronavirus and Deltacoronavirus. Currently, four seasonal coronaviruses (HCoV-229E, - OC43, -NL63 and -HKU1) are circulating among the world’s population, which are present year-round in the structure of ARI, and, as a rule, cause damage to the upper respiratory tract of mild and moderate severity, as well as two highly pathogenic coronaviruses-Middle East respiratory syndrome virus (MERS) and new coronavirus infection COVID-19. To develop a model of human resistance to the disease caused by the coronavirus family, the elements, links and ways of protecting the Human-Virus-Environment system were identified. The destructive functions of sixteen proteins of the SARS-CoV-2 strain are considered. Deterministic and statistical models of cells infection risk development have been developed. A parameterized system of human protection against coronavirus infection is proposed.

The economic efficiency of intensive livestock farming on an industrial basis depends on the rational housing of animals, which is largely determined by the presence of an optimal microclimate in the premises. Whatever breed and pedigree qualities the animals may have, without creating the necessary microclimate conditions they are unable to maintain their health and show their potential productive capabilities due to heredity. Between 2018 and 2020, 11 farms in Perm Region were surveyed for respiratory and digestive diseases, skin diseases, and in some cases stress was observed in the animals. The costs of heating livestock buildings are, as a rule, much lower than the losses due to mortality, loss of productivity and overconsumption of feed. The physical properties of the air environment are factors that are not constant and are subject to large fluctuations. To optimize the microclimate in a livestock building, a program algorithm has been developed for a computer. That will create a system, which provides optimal conditions for the maintenance and service of animals and increase the life safety on livestock farms. In this regard, in order to improve conditions for keeping calves and cows, a project for a device to control the parameters of the microclimate in farms in the Perm region has been developed. The microclimate control system is developed on the basis of: Order of the Ministry of Agriculture of the Russian Federation from October 21, 2000 № 622 “On approval of Veterinary rules of keeping cattle for its reproduction, rearing and realization” and Set of rules 106.13330.2012 “Cattle - breeding, poultry - breeding and beast - breeding buildings and premises”. At the heart of the monitoring is an automated analysis and regulation of microclimate parameters. Hardware-software implementation is made on PLC Omron.
