The history of permafrost landscape map compilation is related to the study of ecological problems with permafrost. Permafrost-landscape studies are now widely used in geocryological mapping. Permafrost-landscape classifications and mapping are necessary for studying the trends in development of the natural environment in northern and high-altitude permafrost regions. The cryogenic factor in the permafrost zone plays a leading role in the differentiation of landscapes, so it must be considered during ...

Most high duty parts used in various fields of productions are forged parts made of steel. The conventional forging process chains include an induction heating systems and hot forming equipment. The large amount of consumed energy and an excess of material (flash) are the main factors motivating necessity to optimize the industrial technologies of metal hot forming. A significant economical effect can be achieved through optimization of heating modes and design parameters of induction heaters on ...

Abstract Lead‐free halide perovskites is a novel class of environment‐friendly nonlinear optical materials, that already demonstrate high potential for second harmonics generation (SHG). Here a synthesis protocol is optimized to create single‐crystal CsGeI 3 nanoparticles (NPs) supporting optical Mie resonances that efficiently convert infrared light to visible both via lasing and SHG mechanisms. Such high‐quality resonant NPs allow us to achieve up‐conversion lasing in the broadband excitation wavelength ( ...

As it is known the mining of oil and gas offshore is carried out using the drilling platforms, which are extremely massive and inert. In order to avoid excessive stresses on platform, which is highly inertial object, it consists of few large parts (normally base and legs). Four friction pendulum bearings are used for mechanical link between the base and legs. The bearings functionality is to provide the protection of the platform from all possible mechanical loadings on the legs that might affect ...
