Abstract: This paper focuses on the study and application of a scissor structural element, termed non-crossing angulated element (NCAE). After studying a special NCAE with a constant subtended angle ...

Abstract: In this paper, an annular piezoelectric actuator which can realize reciprocating motion is proposed to provide power for deep-sea bionic system. The actuator adopts a fully open structure, ...

Kilmar Abrego Garcia filed a motion to dismiss the criminal case filed against him arguing that it constituted selective and vindictive prosecution, specifically arguing that the three-year gap ...

Objective: To compare the root canal preparation of primary teeth with reciprocating and rotary NiTi instruments. Material and Methods: Electronic databases (PubMed/MEDLINE, Web of Science, TRIP, ...

Almost every internal combustion vehicle on the planet today uses the classic piston engine. These run by converting heat energy into reciprocating motion, and then rotary motion that ultimately ...
