All-Plasmonic Switching Effect in the Graphene Nanostructures Containing Quantum Emitters.

Nonlinear plasmonic effects in perspective 2D materials containing low-dimensional quantum emitters can be a basis of a novel technological platform for the fabrication of fast all-plasmonic triggers, transistors, and sensors. This article considers the conditions for achieving a strong coupling between the surface plasmon-polariton (SPP) and quantum emitter taking into account the modification of local density of optical states in graphene waveguide. In the condition of strong coupling, nonlinear interaction between two SPP modes propagating along the graphene waveguide integrated with a stub nanoresonator loaded with core-shell semiconductor nanowires (NWs) was investigated.

[MICROCLIMATE CONDITION IN SUBWAY CARS IN THE SUMMER PERIOD OF THE YEAR].

There are presented the results of the work, which aims to identify the relationship between the temperature of air in the salons of subway cars from the heat output of passengers in different people occupancy of cars during "peak hours", and to determine the efficacy offorced air handling regular ventilation or air conditioning system to remove the elevated heat load on passengers. In the work there was used the method of calculating the amount of heat output of 215 passengers (nominal fullness of the chamber) and the simulation method of heat and moisture output of the same number of passengers. The operating system of ventilation has been shown to fail to decline the average temperature of the air in the passenger compartment to the optimum values and most efficient approach for the reducing the heat load on the passengers is the use of air conditioning systems.

[To the issue on the optimization and regulation of microclimate in the subway trains and stations].

There is presented an overview of currently existing regulatory framework governing the parameters of the microclimate in the salons of subway passenger cars and stations. Analysis of the normative documents indicated that they contain very incomplete, contradictory, often unfounded information about the parameters of microclimate parameters in salons of subway rolling stock. Also, there are no clear cut hygienically-sound requirements for the work of imposed on the rolling stock subway systems provide microclimate, including new systems for air conditioning and disinfection.

[Physical factors of the industrial environment and traffic safety].

The paper deals with the problem of optimization of working conditions of engine drivers in the control cabs of up-to-date locomotives, by toughening the sanitary-and-hygienic requirements for the levels of bad industrial factors. The authors associate the optimization of working conditions with the necessity of strengthening the reliability of their driving activity due to the increasing rail movement speeds and the transfer to one-person rolling-stock operation, and other factors.

[Sanitary epidemiologic safety and technical regulations on railway transport].

The author necessitated that requirements on sanitary and epidemiologic safety of life support systems for engine driver cabin (microclimate maintainance system, protection from vibration and noise, illumination, workplace ergonomics, etc) should be included into technical regulations for railway vehicles, both newly constructed and modernized.
