size reduction of high energy materials such as 1, 3, 5, 7-tetranitro- 1, 3, 5, 7-tetraaza cyclooctane (hmx) has considerable influences on improving their explosive characteristics. in this study, nanosized hmx par­ticles were produced using ultrasonically reprecipitation method by applying water as a safe and accessible antisolvent instead of unsafe conventional methods. sem photographs revea...

Rhodamine B, a fluorescent substance, was used as a tracer to investigate in vitro early microleakage from around amalgam restorations in machinable mica glass-ceramic after thermal stress. Five types of amalgam, i.e., low-copper spherical, low-copper lathe-cut, high-copper admixture, high-copper lathe-cut, and high-copper spherical, were examined in the present study. The results indicated tha...

Abstract. The Mediterranean atmosphere is impacted by a variety of natural and anthropogenic aerosols which exert complex variable pressure on the regional climate air quality. This study focuses Western Sea (west longitude 20∘ E) using full POLarization Directionality Earth's Reflectances version 3 (POLDER-3)/Polarization & Anisotropy for Atmospheric Sciences coupled with Observations ...

Abstract The hydromechanics of the fluidized bed processing medium is presented; conditions for its formation, stability, and limits existence are given. stochasticity a two-phase hydromechanical process in has been determined. boundary on surface spherical processed part vibrating machine reservoir considered. It was found that velocity granules during collision with part, addition to chaotic ...

In this paper, a near-field to far-field (NF–FF) transformation for the case of spherical scanning using equivalent magnetic currents (EMCs) and matrix methods is addressed. It is based on the decoupling of the field components and the iterative retrieval of the radial component of the electric field. The technique is applied for far-field calculation as well as for the estimation of the curren...

Analytic results for twoand three-centre integrals are derived for the truncated spherical-wave basis set designed for first-principles pseudopotential calculations within density-functional theory. These allow the overlap, kinetic energy and non-local pseudopotential matrix elements to be calculated efficiently and accurately. In particular, the scaling of the computational effort with maximum...

Apolipoprotein E (apoE) enters the plasma as a component of discoidal HDL and is subsequently incorporated into spherical HDL, most of which contain apoE as the sole apolipoprotein. This study investigates the regulation, origins, and structure of spherical, apoE-containing HDLs and their remodeling by cholesteryl ester transfer protein (CETP). When the ability of discoidal reconstituted high d...

PURPOSE The purpose of this study was to characterize the central and peripheral refraction across the horizontal meridian of the visual field before and after myopic corneal refractive therapy (CRT) with contact lenses. METHODS Twenty-eight right eyes from 28 subjects (mean age +/- SD = 24.6 +/- 6.3 years) were fitted with Paragon CRT contact lenses to treat myopia between -0.88 and -5.25 D ...
