In friction stir welding frictional heat is generated by the rotating tool, sliding over the stationary plate along the weld centre. Tool being the only source of heat producing member, its geometrical design influences the heat generation rate. In this present work, effects of variation in tool shoulder and tool pin taper angles on thermal history during joining are analysed. Tools with triang...

OBJECTIVE Observe the effect of Tai Chi in combination with auricular plaster therapy on treating obesity patient with secondary hyperlipidemia. METHOD Select 45 patients who suffer from simple obesity and secondary hyperlipidemia and then adopt random digital table to divide them into a Tai Chi group, an auricular plaster therapy group and a combination group. Each group consists of 15 patie...

PURPOSE To evaluate the effect of particulate dentin-plaster of Paris with and without platelet-rich plasma (PRP) on bone healing and new bone formation around titanium dental implants in a canine model. Histologic sections and histomorphometric analysis of the defects were obtained at 6 and 12 weeks after surgery. MATERIALS AND METHODS Three circular bone defects were surgically prepared in ...

A plaster statue is an object created from a mold made from a stone statue, for example, and into which plaster is poured and hardened. The delicate shape is lost, however, during the molding process, and an issue arises in that the plaster statue has a smoother shape than does the original statue. Consequently in this research, by applying a sharpening filter to the 3D shape data of a plaster ...

Material and methods In 1965, Cotrel and Morel describing the EDF plaster jacket technique stated that “in young children, it should be feasible not only to prevent further progression but above all to use the child’s growth to regress structural vertebral and thoracic deformities”. Before the child start walking, we use a plaster shell in bending correction. After walking, an underarm plaster ...

Hypertrichosis refers to increased vellus hair growth and is independent to androgen excess. The acquired localized hypertrichosis (ALH) is one of the typical hypertrichosis, which mainly results from chronic irritation, inflammation, friction, and occlusion by plaster of Paris. Here, we report a young boy who had ALH on his right hand following a closed fracture with internal fixation and plas...

Background: The orthodontic models can be divided into two categories, namely, working models and study models. Shaping study model is required for orthodontists. Traditionally, we shape the model with a trimmer or a base. The objective of this study was to establish the process of manufacturing orthodontic study models with the support of Computer-Aided Design (CAD) and Fused Deposition Modeli...
