Pressure effects on the electron transport and structure of Nd12xSrxMnO3 (x50.45, 0.5) were investigated in the range from ambient to ;6 GPa. In Nd0.55Sr0.45MnO3, the low-temperature ferromagnetic metallic state is suppressed and a low-temperature insulating state is induced by pressure. In Nd0.5Sr0.5MnO3, the CE-type antiferromagnetic charge-ordering state is suppressed by pressure. Under pres...

background central dialysate fluid delivery systems (cdds) are used by dialysis centers in japan, and although these systems are effective at delivering dialysate, they have a complex piping network with numerous sites where contamination can develop. in japan, cleaning disinfectants have been clinically evaluated based on endotoxin levels and bacterial counts, but there have been no published ...

Spectroscop ic studies of laser -induced p lasm a from a high -temperature superconducting mater ial, v iz., YBa2Cu 3O7 (YBCO), have been carried out. Electron temperature and electron density measurements were made from spectral data. The Stark broadening of emission lin es was used to determ ine the electron density, an d the ratio of line in tensities was exploited for the determ ination of ...

In this paper, a numerical study of barrier characterization effects on the high-temperature internal performance of an InGaAsP multi-quantum well laser is presented. The softwareused for this purpose self-consistently combines the three-dimensional simulation of carrier transports, self-heating, and optical waveguiding. The laser model calculates all relevant physical mechanisms, including the...

Nonlinear gyrokinetic simulations of microturbulence simultaneously driven by electron temperature gradient modes, trapped electron modes, and ion temperature gradient modes are presented, covering both electron and ion spatiotemporal scales self-consistently. It is found that, for realistic ion heat (and particle) flux levels and in the presence of unstable electron temperature gradient modes,...

Irradiation of polymers is one of the most effective and economical methods for modifying their properties and for changing their applications. In this study, an extrusion grade polypropylene (PP) was treated by electron beam irradiation to produce a PP suitable for injection molding. Irradiation was carried out at different doses (0-80 kGy) under atmosphere air and at ambient temperature. Melt...
