During photometric measurements involving the use of photometric lamps it is necessary that the filament of lamp takes a strictly predetermined position with respect to the photodetector and the optical axis of the photometric setup.The errors in positioning of alignment filament with respect to the optical axis of the measuring system lead to incr
The spatial layout and arrangement of obstacles in the built environment significantly affect its evacuation performance.However, few researchers focus on pedestrian simulation-based design optimization of built environment under emergency evacuation conditions.In this paper, we aim to evaluate the evacuation performance of optimized design Wok Set
The article considers a chemical variation of accessory and ore-forming chrome spinels from the Kraka ultramafic massif at the different scales, from the deposit to the thin section.A correlation analysis of compositional and structural features of ultramafic rocks and ores was performed.The ultramafic rocks and chromitites in the studied massif sh
