In the present work, we report a suitable approach for the preparation of BaTiO3 nanostructures via the hydrothermal condition using Dolapix ET85 as surfactant. The powders were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), field emission transmission electron microscopy (FETEM), selected area electron diffra...

the ultra-nanocrystalline diamond (uncd) was synthesized by the detonation of a high explosive mixture in water confinement. the presence of a diamond phase was revealed by x-ray diffraction (xrd) and transmission electron microscopy (tem). x-ray line broadening (xrlb) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. the micro st...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...

PURPOSE To develop a rapid stimulated echo acquisition mode (STEAM) MRI technique for "black-blood" imaging of the human heart that overcomes the single-slice limitation and partially compromised blood suppression associated with double inversion-recovery techniques. MATERIALS AND METHODS Black-blood multislice images of the heart along anatomic orientations and triggered to end diastole were...

Pulsars discovered since the end of the EGRET mission coincident with unidentified highenergy γ-ray sources are prime targets for AGILE. Both general surveys and targeted observations have been successful in finding energetic young pulsars in the plane of the Galaxy. For the latter, hard X-ray imaging followed by deep radio searches of X-ray sources is a proven route. High-resolution Chandra X-...

In one space dimension the standard conservation law has the form A class of high resolution multidimensional wave-propagation algorithms is described for general time-dependent hyperbolic systems. The methods are based on solving Riemann problems and qt 1 f(q)x 5 0, (1) applying limiter functions to the resulting waves, which are then propagated in a multidimensional manner. For nonlinear syst...
