As mobile multimedia services expand, user behavior will become more diverse and the control of service quality from the user’s perspective will become more important in service design. The quality of the network is one of the critical factors determining mobile service quality. However, this has mainly been evaluated in objective physical terms, such as delay reduction and bandwidth expansion....

The purpose of this study is to evaluate the possibility of developing a cylindrical sustained-release dosage form for theophylline directly by means of a ram extrusion process. In particular, the formulations contained: stearic acid as a low melting binder, monohydrate lactose and polyethylene glycol 6000 as hydrophilic fillers. The influence of type and percentage of the components was studie...

The aim of this study was to determine surface roughness and topography of polished dental resin-based nanocomposites. Four representative dental resin-based nanocomposites were tested in the study: two nanohybrids (Filtek Z550 and Tetric EvoCeram) and two nanofilled (Filtek Ultimate Body and Filtek Ultimate Translucent); and two reference materials: one microfilled (Gradia Direct) and one micr...

X-ray computed tomography (XCT) provides a volumetric map of a specimen in three dimensions, generated from a set of radiographs. Due to the speed and quality of measurement, XCT systems with cone beam geometry and matrix detectors have become widely used. Continuous improvements in the quality and performance of Xray tubes and devices have led to cone beam XCT systems which can now achieve spa...

Cohesive polydensified matrix (CPM®) hyaluronic acid fillers are now available with or without lidocaine. The aim of this study was to investigate the safety and performance of CPM® fillers with lidocaine in the clinical setting. In an open-label, prospective, postmarketing study, 108 patients from seven sites in Germany and Denmark were treated with one or more lidocaine-containing CPM® filler...

In this study, we investigate the use of pauses and pause fillers in Mandarin Chinese. Our analysis is based on 267 spoken monologues from a Mandarin proficiency test. We identify two basic pause fillers in Mandarin: e and en. We find that males use more e than females, but there is no difference between them on the frequency of en. Therefore, the proportion of nasal-final pause fillers is high...

normal 0 false false false en-us x-none fa background : the growing interest in filler injection requires a more comprehensive knowledge about the complications of this procedure. methods : a total of 5 cases with debilitating chronic complications following filler injection who were referred to al-zahra hospital, isfahan are presented in this report. results : the outcome of treatment for two ...

This study evaluated weight loss and surface roughening after toothbrushing of different resin composites: one packable (Solitaire 2, Heraeus Kulzer), one microhybrid (Charisma, Heraeus Kulzer), one nanohybrid (Simile, Pentron) and one microfilled (Durafill VS, Heraeus Kulzer). Cylindrical specimens (n = 20) were prepared. Half of the samples were submitted to 60,000 strokes, at 4 Hz, with a de...

chewable ferrous fumarate tablet is the best iron dosage form for children due to better compliance and lower teeth staining compared to the oral drop. because of the different desirable properties of chewable tablets and the opposing effects of fillers on them, the mathematical experimental design was used as the formulation approach. different series of formulations based on single filler (la...

Over the years, the ev8 code has been a very useful tool for the study of nuclear mean-field theory. Its main characteristic is that it solves the Hartree-Fock plus BCS equations for Skyrme type functionals via a discretization of the individual wave-functions on a three-dimensional cartesian mesh. This allows maximal flexibility in the determination of the nuclear shape by the variational proc...
