Data fabrication and article retraction: how not to get lost in the woods.
ON February 12, we retracted, via electronic publication ahead of print, three articles after we were notified that the lead author, Scott Reuben, fabricated data in these reports.* As I write this, several more articles published in other journals are in the process of being retracted from this author for the same reason. The purpose of this editorial is not to discuss the everpresent problem ...
متن کاملgingival retraction methods for fabrication of fixed partial denture:literature review
abstract fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. this is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). if the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among ...
متن کاملDesign and fabrication of an ultrasonic thermoacoustic generator using metal nanocoatings (Research Article)
In this paper, we design, simulate, and build an ultrasonic heat generator. In thermoacoustics, heat generated by the passage of alternating current through a thin conductor produces a sound wave. In this method, unlike other methods of sound production, moving parts are not used to vibrate air molecules, and as a result, the frequency response of these generators is flatter than other sound ge...
متن کاملRetraction of article: Stable chloroplast transformation of immature scutella and inflorescences in wheat (Triticum aestivum L.).
Dear editor; After receiving the comments from the readers, we checked the results carefully and decided to repeat all the experiments. As the first author has already left the lab, other members are still trying to repeat these experiments. Because it takes a long time to have these experiments redone, we decide to retract our paper entitled “Stable chloroplast transformation of immature scute...
