During the past 20 years, a variety of alloplastic materials have been introduced for chin augmentation. Mersilene mesh (Ethicon, Sommerville, NJ), introduced in 1950, demonstrates many qualities that make it an ideal implant. This article reviews the senior author's (S.W.P.) successful 14-year experience using Mersilene mesh chin implants. Between 1983 and 1997, 264 patients underwent chin imp...

In this paper, a novel integrated structure is proposed in order to reduce the axial length of the high speed of a magnetically suspended motor (HSMSM) to ensure the maximum speed, which combines radial displacement sensor probes and the permanent magnet biased radial magnetic bearing in HSMSM. The sensor probes are integrated in the magnetic bearing, and the sensor preamplifiers are placed in ...

We consider luminescence in photo-excited neutral C60 using the Su-SchriefferHeeger model applied to a single C60 molecule. To calculate the luminescence we use a collective coordinate method where our collective coordinate resembles the displacement of the carbon atoms of the Hg(8) phonon mode and extrapolates between the ground state ”dimerisation” and the exciton polaron. There is good agree...

The present case report highlights about management of taurodontism which is a developmental anomaly characterized by the lack of constriction at the level of the cementoenamel junction, vertically elongated pulp chambers and apical displacement of the pulpal floor. Permanent molar teeth are commonly affected teeth. Its morphology might hamper the location of orifices and can create difficultie...

Introduction The costs of natural disasters, such as earthquakes and floods, and of wars and other man-made catastrophes go beyond the immediate loss of life, property, infrastructure and livelihood. The public health crisis that unfolds over ensuing weeks and months leaves much deeper, permanent scars in the form of reduced quality of life and disrupted national economies. 1 These effects are ...

In this paper, we discuss a force sensing by microrobot called magnetically driven microtool (MMT) in a microfluidic chip. On-chip force sensor is fabricated by assembling layers to neglect the friction issue and it is actuated by permanent magnets, which supply mN order force to stimulate microorganisms. The displacement is magnified by designing beams on the force sensor and the sensor achiev...

The article follows the deductive method, with a hermeneutic paradigm and qualitative approach. Online learning has allowed students to have academic preparation without having go traditional educational center, where there is already physical displacement are no pre-established schedules, in addition, they allow lowering travel tuition costs. Permanent relearning, asynchronous models self-lear...

We study the displacement memory effect and its connection with extended-BMS symmetries near horizon of black holes. show there is a permanent shift in geodesic deviation vector relating two nearby timelike geodesics placed close to holes, upon passage gravitational waves. also relate this asymptotic hole spacetimes. The relative position detectors shown be induced by combination BMS generators...

lateral and anterior displacements of mandible may cause malocclusion. the aim of this study was to determine the prevalence of these displacements in a population of 597 childrens age 12 in mashhad secondary schools. displacment of mandible was shown to be in 11.8 percent of the population (6.2 percent anterior and 5.6 percent lateral displacement).anterior displacement of mandible was diagnos...

OBJECTIVE To evaluate the incidence of intraoperative and early postoperative complications (up to two months after implant) of endocardial permanent pacemaker insertion in all patients under-going a first implant at a referral centre. METHODS Prospective evaluation of all endocardial pacemaker implantation procedures performed from April 1992 to January 1994 carried out by completion of stan...
