background: parkinson's disease as a progressive disorder of the nervous system leads to the disability of postural control system. objectives: in the present study the effects of pilates exercises on functional balance in patients with parkinson's was investigated. materials and methods: this control trial included 30 patients with idiopathic parkinson's disease who were selecte...

The best plan for success is to begin with the end in mind. It generally is agreed that the successful treatment of a badly broken down tooth with pulpal disease depends not only good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy. The primary purpose of the post is to retain a core that can be used to retain definitive prostheses. A post an...

Since the advent of post and core systems, dentists have regularly accepted the traditional cast and post and core as choice of treatment modality to restore a badly broken root canal treated tooth. The important question being, if at all the cast, post is indicated in every case. Other concept being that a cast post compared to a prefabricated post improves the strength of a root canal treated...

The goal of this paper is the proposal and evaluation of a ray-casting strategy that takes advantage of the spatial and temporal coherence in image-space as well as in object-space in order to speed up rendering. It is based on a double structure: in image-space, a temporal buffer that stores for each pixel the next instant of time in which the pixel must be recomputed, and in object-space a Te...

A study is conducted on the state-of-the-art manufacturing practices of conventional industrial and research-and-development (R&D) firms manufacturing electric induction motors. It is found that current industrial processes cannot produce high-performance motors, and that current R&D processes are too costly. A new manufacturing process for fabricating the rotors of squirrel cage induction moto...

Centrifugal casting is one of the advanced casting branches widely used in the metallurgical industry in which the centrifugal force helps strengthen the workpiece material. The present work attempt to study the effect of the horizontal and vertical centrifugal casting parameters included the centrifugal mold rotation speeds and G-factors values on the quality of the product. The work has been ...

Many graphical objects can be represented by swept volumes (including its subset – generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept volumes using image templates. We utilise scalar fields as our underlying data type, and employ volume ray casting techniques for rendering swept volumes in their original s...
