OBJECTIVE The aim of the study is to evaluate the stress distribution in tooth supported 5-unit fixed partial denture (FPD) having tooth as pier abutment using rigid and nonrigid connectors respectively, under simultaneous and progressive loading. MATERIAL AND METHODS The three-dimensional (3D) finite element program (ANSYS software) was used to construct the mathematical model. Two 5-unit FP...
background and aims. there are many edentulous people with severely resorbed residual ridges and non-resilient lining mucosa that are unable to tolerate occlusal forces during functional and parafunctional movements. lining the tissue surface of dentures with a flexible material can theoretically distribute and absorb forces with cushioning effect. the aim of this study was to evaluate the effe...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
Stabilization of a bicycle with two-wheel steering and two-wheel driving by driving forces at low speed Chihiro Nakagawa, Yoshihiro Suda, Kimihiko Nakano and Shoichiro Takehara Department of Engineering Synthesis, University of Tokyo, 4-6-1, Komaba, Meguro, Tokyo, Japan Institute of Industrial Science, University of Tokyo, 4-6-1, Komaba, Meguro, Tokyo, Japan Department of Mechanical Engineering...
The grasping force of traditional under-actuated hands can hardly be kept during grasping. It is a crucial task to improve the grasping forces of robotic hands. Changeable grasping forces unit is one of the most effective solutions. This paper proposed a linkage changeable grasping force (CGF) unit integrated with linkage under-actuation mechanism in accordance with summary of proceeding work o...
Sustainable development requires a nondeclining growth of the productive base or comprehensive wealth an economy. We use concept inclusive (IW) to assess national and sustainability. IW comprises natural, human, produced capital. With multisource data GIS technology, this study created pixel-level database for China Japan in 2000, 2005, 2010, 2015. Using high-resolution data, we first conducted...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
