The behavior and structure of Rb are explored up to 264 GPa, a pressure at which the density is increased more than eightfold. previously predicted double-hexagonal close packed stable above 200 while lower pressures change in compressibility 30 GPa arises from $s$-$d$ charge transfer. Above authors find that has regular compression $d$-type transition metal.

eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...

Pressure sores are a major problem frequently encountered by persons who use wheelchairs. Custom seat design, including contoured seating and various modular seating devices, has become an important option for pressure relief, especially when the market size is small and the variations of individual needs and requirements are large. An alternative approach in custom seating design for pressure ...

Retrograde locked intramedullary nailing has gradually been widely used to treat femoral supracondylar fractures. Because a standard femoral supracondylar nail has unique disadvantages: high price and potentially inducing a femoral shaft stress fracture, it is often replaced by a traditional femoral or tibial locked nail. A biomechanical comparison was therefore made between both traditional lo...
