statement of the problem: although all-ceramic restorations are broadly used, there is a lack of information concerning how their fit is affected by fabrication procedure and marginal configuration. purpose: the purpose of this study was to evaluate the marginal fit of zirconia cad/cam ceramic crowns before and after porcelain firing. the influence of finish line configuration on the marginal f...

INTRODUCTION Renal allograft half-life time (t½) is the most straightforward representation of long-term graft survival. Since some statistical models overestimate this parameter, we compare different approaches to evaluate t½. PATIENTS AND METHODS Patients with a 1-year functioning graft transplanted in Spain during 1990, 1994, 1998 and 2002 were included. Exponential, Weibull, gamma, lognor...
critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Abstract Bispecific antibodies (bsAbs) are often composed of more than two component chains, such as Fabs-in-tandem immunoglobin (FIT-Ig) comprising three different which bring challenges for generating a high proportion the correctly assembled bsAbs in stable cell line. During CHO-K1 line construction FIT-Ig, we investigated FIT-Ig chain ratio transfection, where sets expression vectors were d...
educational researchers have provided evidence that teachers’ emotional intelligence has strong effects on various aspects of teaching and learning. yet, in the field of teaching english to speakers of other languages (tesol), inquiry into teachers’ emotional intelligence is nearly limited. given its documented powerful impact on teaching practices and student learning, it is critical to pursue...
Squares are experimental force versus extension data for 97 kb X-DNA dimers from figure 3 of (2); solid line is a fit of the entropic force required to extend a worm-like polymer. The fit parameters are the DNA length (L = 32.80 + 0.10 plm) and the persistence length (A = 53.4 ± 2.3 nm). Shown for comparison (dashed curve) is the freely jointed chain model (2) with L = 32.7 KILm and a segment l...
Background and purpose: One of the major challenges for dentists is providing the patients with a crown of appropriate marginal fit and marginal gap. Preparation of a 135° finish line has some advantages such as technical ease and appropriate finish line record. Nevertheless, few studies investigated this type of finish line. The current study aimed at comparing marginal fit and marginal gap in...
