INTRODUCTION Emulsion formulations are one of hard tasks since there are a lot of emulsifiers which can be selected. To save time in emulsifier selection, the hydrophile-lipohile balance (HLB) system has been used for choosing proper emulsifiers. Lipophilic compounds (oils, fats, and waxes) have an individual value called “required HLB”. An emulsifier or blend of emulsifiers, having an HLB equa...

The intrinsic magnetic relaxations in metallic films will be discussed. It will be shown that the intrinsic damping mechanism in metals is caused by incoherent scattering of itinerant electron-hole pair excitations by phonons and magnons. Berger @L. Berger, Phys. Rev. B 54, 9353 ~1996!# showed that the interaction between spin waves and itinerant electrons in multilayers can lead to interface G...

The design and fabrication of oxygen barrier films is important for both fundamental and industrial applications. We prepared three different thin films composed of graphene oxide (GO) and laponite (LN), a typical low cost inorganic clay, with the GO/LN volume ratios of 1.9/0.1, 1.7/0.3 and 1.5/0.5 together with a double layer film of the GO and LN. We found that the films with GO/LN = 1.9/0.1 ...

Abstract A nuclear emulsion film is a three-dimensional tracking device that widely used in cosmic-ray and high-energy physics experiments. Scanning with wide angle acceptance crucial for obtaining track information films. This study presents new method developed high-speed recognition of films neutrino–nucleus interaction measurements. The technique can be to measure tracks charged particles f...

OBJECTIVES To examine whether a mixed lipid emulsion reduces the incidence of parenteral nutrition associated cholestasis (PNAC) in extremely low birth weight (ELBW, <1000 g) infants. STUDY DESIGN This double-blind randomized trial of 230 ELBW infants (June 2012-October 2015) was performed at a single level IV neonatal intensive care unit. Patients received either a mixed lipid emulsion compo...

abstractbackgrounds: md-55-2 is one of the radiochromic film models with the sensitivity suitable for dose measurements ranging from 5 to 100 gy.  however, this lower limit makes the film impractical for its applications in many areas such as brachytherapy source dosimetry.materials and methods: in this project, the useful range of the film has been extended by using a multilayer film technique...

This study investigates an X-ray dose measurement method for computed tomography using Gafchromic films. Nonuniformity of the active layer is a major problem in Gafchromic films. In radiotherapy, nonuniformity error is reduced by applying the double-exposure technique, but this is impractical in diagnostic radiology because of the heel effect. Therefore, we propose replacing the X-rays in the d...
