An accurate transfer of the inter-occlusal relationship to the articula-tor is essential for the fabrication of a prosthesis. 1 The accurate articulation of working casts results in less time spent adjusting occlusion. This has a direct effect on the quality of the restoration and the operational cost of treatment. 2 Therefore, an ideal registration material and technique combination would allo...

Intrinsic membrane proteins represent a large fraction of the proteins produced by living organisms and perform many crucial functions. Structural and functional characterization of membrane proteins generally requires that they be extracted from the native lipid bilayer and solubilized with a small synthetic amphiphile, for example, a detergent. We describe the development of a small molecule ...

This study investigates the seismic response of a horizontal axis wind turbine on two bottom-fixed support structures for transitional water depths (30-60 m), a tripod and a jacket, both resting on pile foundations. Fully coupled, nonlinear time-domain simulations on full system models are carried out under combined wind-wave-earthquake loadings, for different load cases, considering fixed and ...

There are many tools that carry cameras. Their working domain is usually surveillance, surface inspection, and broadcasting. Devices like rovers, gantries, and aircrafts often possess video cameras. The task is usually to maneuver the vehicle and position the camera to obtain the desired fields-of-view. A platform widely used in the broadcasting industry can be seen in Figure 1. The specific pa...

This paper applies dimensional synthesis to explore the geometric design of dexterous three-fingered robotic hands for maximizing precision manipulation workspace, in which the hand stably moves an object with respect to the palm of the hand, with contacts only on the fingertips. We focus primarily on the tripod grasp, which is the most commonly used grasp for precision manipulation. We systema...

BACKGROUND Clinical features of Charcot-Marie-Tooth disease type 1A (CMT1A) include slowly progressive distal muscle weakness, atrophy and sensory loss. Upper-limb involvement results in reduced manual dexterity interfering with the execution of daily activities. OBJECTIVE To identify which hand function impairments are determinants of manual dexterity in CMT1A. METHODS In a cross-sectional...

There is presently a lack of knowledge of scour progression for complex offshore foundation structures, such as Tripod foundations for offshore wind turbines. Typically, scour is investigated in physical model tests. As an extension, parts of the investigations could be carried out by using numerical methods; however, such numerical methods require that all relevant processes leading to scour a...

Distinct electromagnetic properties can emerge from the three-dimensional (3D) configuration of a plasmonic nanostructure. Furthermore, the reconfiguration of a dynamic plasmonic nanostructure, driven by physical or chemical stimuli, may generate a tailored plasmonic response. In this work, we constructed a 3D reconfigurable plasmonic nanostructure with controllable, reversible conformational t...

the undesirable effects and consequences of occupational fatal accidents have placed a great emphasis on applying preventive measures. this study was aimed to analyze and specify the latent causes of occupational fatal accidents in exir chemical plant, urmia - iran in 2008-2009. the analytical tripod-beta method was used. a geographic information system (gis) was then used to determine a list o...
