The authors investigate the fire-protective efficiency of a basalt roll material, which is used for light steel thin-walled structures. The values of fire-protective efficiency for the steel C-shaped profiles without fire protection made of basalt wo

We report on the observation and study of the magneto-ratchet effect in a graphene-based two-dimensional metamaterial formed by a graphite gate that is placed below a graphene monolayer and patterned with an array of triangular antidots. We demonstra

The article demonstrates the both theoretical and actual fire resistance limits of the composite I-shaped and box-shaped thin-walled steel structures in compression conditions under the standard fire load. The calculation was based on the Eurocode 3

Our studies of the cyclotron resonance (CR) photoresistance in GaAs-based two-dimensional electron systems (2DES) reveal an anomalously low sensitivity to the helicity of the incoming circularly polarized terahertz radiation. We find that this anomal

The article discusses the possibility of using the elevators as the main evacuation path from high-rise buildings. It starts by analysis of the reasons, which make effective evacuation of people from high-rise buildings difficult. The high multi-stor

The article considers elevator application as an integral part of the main evacuation path from high-rise multi-storey buildings and structures. The evacuation ways are rather long in this building type. It makes the evacuation process difficult and
