This article concerns the stability of the air-water interface subjected to a 2D attractive van der Waals stress. The physical problem models the setup of a Wilhelmy plate experiment prior to three-phase contact line formation. We present and employ an unambiguous condition to quantify the stability limit in terms of the distance of closest approach of a solid cylindrical plate of parabolic cro...

We are concerned with texture-mapping recovered geometry with photographs. The photographs overlap, and typically a point in the geometry is covered by multiple photographs. The geometry is represented as a triangular mesh which may be recovered either from photographs or from laser range data. From photographs that have been aligned with the geometry, we wish to manufacture specialized texture...

In this study the effects of corrugated absorber plate and using aerosol-carbon black nanofluid on heat transfer and turbulent flow in solar collectors with double application and air heating collectors, were numerically investigated. The two-dimensional continuity, momentum and energy equation were solved by finite volume and SIMPLE algorithm. In the present investigation all the simulations w...

The clavicle has a complex geometry that makes plate fixation technically difficult. The current study aims to measure the anatomical parameters of Chinese clavicles as reference for plate design. One hundred clavicles were analyzed. The clavicle bone model was reconstructed by using computed tomography images. The length, diameters, and curvatures of the clavicle were then measured. The female...

An exact solution of the convective-dlffuslon equation for fully developed parallel plate lammar flow was obtamed It allows the denvatlon of theoretical relatlonshps for calculating the Peclet number m the axmlly dispersed plug flow model and the concentration dlstrlbutlon perpendicular to the direction of the flow, provided that the correspondmg solution of this model IS known. The convective-...

In this paper, we investigate rarefied jet gas flows out of a two-dimensional slit and impinges on a flat plate which is set vertically to the plume flow direction. With a relation between velocity-directions and geometry-positions, we obtain several analytical collisionless flow property distributions in front of the plate. This study further provides near-plate collisionless flow properties i...

The coupling between plate motions and mantle convection is investigated using a fully dynamic numerical model consisting of a thin non-Newtonian layer which is dynamically coupled to a thick Newtonian viscous layer. The non-Newtonian layer has a simple power-law rheology characterized by power-law index n and stiffness constant pp. A systematic investigation of steady, single cell configuratio...

Background Reverse total shoulder arthroplasty is an increasingly utilized treatment option for glenohumeral arthritis with massive, irreparable rotator cuff disruption associated with loss of glenohumeral stability and function. Several reverse shoulder implant designs from different manufacturers have been introduced to the market in recent years. Fixation of the glenoid base plate has been s...
