METALLURGICAL CHARACTERISTICS OF ARMOUR STEEL WELDED JOINTS USED FOR COMBAT VEHICLE CONSTRUCTION


Evolution of the Upper Reaches of Fluvial Systems within the Area of the East European Plain Glaciated during MIS 6

The headwaters of fluvial systems on the East European Plain Gaming Accessory between the boundaries of the Marine Isotope Stage 2 (MIS 2) and MIS 6 glaciations evolved during the last 150,000 years.At least three main events of high surface runoff caused intensive erosion: at the end of MIS 6, at the end of MIS 2 and in the Middle Holocene.Erosion

Ephemeral superconductivity atop the false vacuum

Abstract A many-body system in the vicinity of a first-order phase transition may get trapped in a local minimum of the free energy landscape.These so-called false-vacuum states may survive for exceedingly long times if the barrier for their decay is high enough.The rich phase diagram obtained in graphene multilayer devices presents a unique opport

Center of Rigidity and Center of Shear in Wall-Frame Systems

In case of torsion in buildings, additional earthquake forces affect the structure and internal forces and displacements increases.For this reason, it is important to place the bearing systems in the plan as much as possible to reduce the torsion effect.To minimize torsion effects, the center of mass and center of rigidity should be as close as pos
