    The .577 Nitro Express is a large-bore centerfire rifle cartridge designed for the purpose of hunting large game such as elephant. This cartridge is used almost exclusively in single-shot and double express rifles for hunting in the Tropics or hot climates in general and is a cartridge associated with the golden age of African safaris and Indian shikars.

  4. Moving heat source model for thin plates - Wikipedia

    en.wikipedia.org/wiki/Moving_heat_source_model...

    Moving heat source in on a thin plate. In heat transfer, moving heat sources is an engineering problem, particularly in welding. In the early 20th century, welding engineers began studying moving heat sources in thin plates, both empirically and theoretically. [1] Depending on welding parameters, plate geometry and material properties, the ...

  8. Metal profiles - Wikipedia

    en.wikipedia.org/wiki/Metal_profiles

    Metal profile sheets are metal structural members that due to the fact they can have different profiles, with different heights and different thickness, engineers and architects can use them for a variety of buildings, from a simple industrial building to a high demand design building. Trapezoidal profiles are large metal structural members ...

  9. Steel plate shear wall - Wikipedia

    en.wikipedia.org/wiki/Steel_plate_shear_wall

    A steel plate shear element consists of steel infill plates bounded by a column-beam system. When these infill plates occupy each level within a framed bay of a structure, they constitute an SPW. Its behaviour is analogous to a vertical plate girder cantilevered from its base. Similar to plate girders, the SPW system optimizes component ...
