Objectives: To determine whether information available prior to and during anesthesia residency training can predict American Board of Anesthesiology (ABA) Part 1 (Written) performance and help identify anesthesia residents at risk for failure. Methods: Retrospective analysis of 97 anesthesiology residents’ academic files at a single Midwestern residency program. ABA Part 1 score was used as th...

to evaluate the ultimate compressive strength of five composite resins after 1 hour, 24 hours, 7 days and 1 month. twenty four cylindrical 4 mm×8mm specimens of each commonly used composite resins in posterior region (nulite-f , z250 , p60, biscore, tetric ceram hb) were prepared. each group of composite resins were divided into four time groups of 1 h, 24 h, 7 days and 1 month. all of specimen...

BACKGROUND The In-Training Examination in Internal Medicine (IM-ITE) has been offered annually to all trainees in U.S. medical residency programs since 1988. Its purpose is to provide residents and program directors with an objective assessment of each resident's personal performance on a written, multiple-choice examination and the performance of the residency program compared with that of its...

In this work, we examine the advantages of using multiple types behaviours in recommendation systems. Intuitively, each user often takes some implicit actions (e.g., click) before making an explicit decision purchase). Previous studies show that and feedback has different roles for a useful recommendation. However, these either exploit separately or ignore semantics sequential interactions betw...

The marginal fracture toughness of several types of composite resins was determined by means of the rattler test. Microparticle-filled resins showed significantly higher marginal fracture toughness than conventional composites. Posterior restorative composites were intermediate between MFRs and conventional composites. Amalgams were inferior to restorative resins. These data correspond with the...

This article focuses on the use of lesson study (LS) in initial teacher education (ITE) from a mapping review international research published peer-reviewed journals. method enables identification characteristic features field along with any gaps existing evidence base. The authors map out variations ITE LS practices by employing seven-dimensional framework to illustrate range and draw conclusi...

Strong base anion-exchange resins represent an important option for water utilities and homeowners to address growing concerns with nitrate, arsenate, and perchlorate contamination of source waters. Most commercially available anion-exchange resins employ quaternary amine functional groups. Previous research has provided contradictory evidence regarding whether these resins serve as sources of ...

BACKGROUND Chemicals that have estrogenic activity (EA) can potentially cause adverse health effects in mammals including humans, sometimes at low doses in fetal through juvenile stages with effects detected in adults. Polycarbonate (PC) thermoplastic resins made from bisphenol A (BPA), a chemical that has EA, are now often avoided in products used by babies. Other BPA-free thermoplastic resins...

A new, easy and cost-effective synthetic procedure for the preparation of thermosetting melamine-based epoxy resins is reported. By this innovative synthetic method, different kinds of resins can be obtained just by mixing the reagents in the presence of a catalyst without solvent and with mild curing conditions. Two types of resins were synthesized using melamine and a glycidyl derivative (res...
