The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape). Polyvinyl siloxane impressions and Type IV gypsum model...

OBJECTIVES The aim of this study was to investigate the internal fit (IF) of glass-infiltrated alumina (ICA--In-Ceram Alumina), yttria-stabilized tetragonal zirconia polycrystals (Y-TZP--IPS e.max ZirCAD), and metal-ceramic (MC--Ni-Cr alloy) crowns. MATERIAL AND METHODS Sixty standardized resin-tooth replicas of a maxillary first molar were produced for crown placement and divided into 3 grou...

PURPOSE To assess the internal reliability, construct and concurrent validity and responsiveness of the Northwick Park Therapy Dependency Assessment (NPTDA) scale. METHOD A cohort of 2505 neurorehabilitation patients submitted to the UK Rehabilitation Outcomes Collaborative database. Cronbach's coefficient-α was used to assess internal reliability and factor analysis (FA) to assess construct ...

Materials and Methods: This secondary analysis examines 200 Iranian mothers registered to receive prenatal care in health centers in Kerman, Iran. ...

Grid computing can be considered large-scale distributed cluster and parallel network processing. The two most important issues in managing user work are resource allocation scheduling of required resources. When jobs submitted, they managed by intermediaries who find allocate the right After stage, scheduled on existing resources according to user's In grid systems with traditional scheduling,...

Understanding the regulation of key genes involved in plant iron acquisition is of crucial importance for breeding of micronutrient-enriched crops. The basic helix-loop-helix protein FER-LIKE FE DEFICIENCY-INDUCED TRANSCRIPTION FACTOR (FIT), a central regulator of Fe acquisition in roots, is regulated by environmental cues and internal requirements for iron at the transcriptional and posttransc...
