Abstract In this paper, the effect of structural relaxation at temperatures below crystallization on internal stress Ni–Nb–Zr thin film amorphous alloy (including metallic glass: TFMG) diaphragms was investigated. We fabiricated diaphragm samples with four compositions. Before fabrication structure by etching, films Si substrate were annealed a temperature (473, 523, and 573 K) for relaxation. ...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

Structure of diaphragm was defined as a transverse strengthener beam which located between beams or girders to keep section geometry. It plays significant role provide the stability bridge and distribute vertical axial loads. The main objective this study investigate influence construction concrete diaphragms T-beams at different distances on dynamic static behavior T-beam structure. methodolog...

OBJECTIVE Diaphragm pacing by phrenic nerve (PN) stimulation is currently used for patients with central respiratory paralysis to be weaned from mechanical ventilation. Electrodes are inserted either through bilateral thoracotomy or through four ports laparoscopy. The aim of this experimental work is to demonstrate the feasibility of trans-mediastinal bilateral implantation of PN electrodes usi...

The flow of a viscous incompressible fluid in cylindrical duct with two serial diaphragms orifices different diameters was studied based on the numerical solution unsteady Navier-Stokes equations. algorithm finite volume method using second-order accurate difference schemes both space and time. TVD (Total-Variation Diminishing) form central-difference scheme flux limiter used for interpolation ...

One hundred prostitutes were interviewed about the prophylactic measures they took against infection. The use of contraceptive diaphragms and clandestine antibiotics correlated significantly with fewer gonococcal infections.
