  • Prospects for crossing territories in the area of transport hubs of railway transport

    This article is descriptive, in this scientific article the role of railway transport in the development of territories is determined, an analysis of domestic regulatory and technical literature in the field of pedestrian traffic, regulatory and methodological data in the field of transfer hubs, describes the formation of pedestrian flows to stopping points of railway transport, taking into account the indicators of the external environment, and also describes the method of forming passenger traffic in the city of Moscow at transport hubs of railway transport.

    Keywords: transport, pedestrian traffic, pedestrian flow, transport hubs, railway transport

  • Effect of additives on the properties of the alloy radio-Mg-Zn-ferrite obtained by sintering heat-radiation

    Promising absorbing materials along with a Ni-Zn-ferrites are Mg-Zn-ferrites, as they are also intensively absorbs electromagnetic waves in the frequency range from 50 MHz to 1000 MHz. The main advantage of the Mg-Zn-ferrite is used as an inexpensive raw material magnesium oxide. The paper presents the results of research to improve the efficiency of broadband radio-magnesium-zinc ferrite by increasing the contribution of the dielectric loss. The influence of alloying elements of the atmosphere gas and cooling after the sintering thermal radiation by absorption of electromagnetic waves. Confirmed cooling efficiency of products after sintering in an atmosphere with reduced oxygen partial pressure to increase the dielectric constant. A model is proposed to explain the increase in the dielectric loss ferrite during cooling in a reducing atmosphere.
