OBJECTIVE To identify the effect of serial casting combined with Botulinum toxin type A (BTX-A) injection on spastic equinus foot. METHOD Twenty-nine children with cerebral palsy who had equinus foot were recruited from the outpatient clinic of Rehabilitation Medicine. The children were divided into 2 groups, one of which received serial casting after BTX-A injection, and the other which only...

The problem of voids and porosity has long plagued the dental technician. Many times an otherwise acceptable casting has had to be discarded because voids or porosities have developed within the casting. Because of numerous variables a technician often does not know the cause of the casting failure. Many investigators have studied variables that may affect the occurrence of voids and porosities...

Casting has various processes like Pre casting Processes, pattern making, core making, molding and mold assembly making, Casting Processes, furnace charging, melting, holding and pouring, and Post casting Processes, shakeout, inspection and dispatch etc. In India there are many foundry have followed conventional and manual operations. Today’s competitive environment has, lower manufacturing cos...

Counteracting the atrophy of skeletal muscle associated with disuse has significant implications for minimizing the wasting and weakness in plaster casting, joint immobilization, and other forms of limb unloading, with relevance to orthopedics, sports medicine, and plastic and reconstructive surgery. We tested the hypothesis that antibody-directed myostatin inhibition would attenuate the loss o...

During casting of aluminum alloys, the partially solidified material is submitted to thermally induced strains that can lead to severe casting defects, such as hot tearing. In this work, carried out in the frame of the European project VIR[CAST], the rheological behavior of a partially solidified AA5182 aluminum alloy has been investigated in order to provide constitutive equations to predict h...

Interactive high quality volume rendering is becoming increasingly more important as the amount of more complex volumetric data steadily grows. While a number of volumetric rendering techniques have been widely used, ray casting has been recognized as an effective approach for generating high quality visualization. However, for most users, the use of ray casting has been limited to datasets tha...

In this article we address the problem of catching objects that move at a relatively large distance from the robot, of the order of tens of times the size of the robot itself. To this purpose, we adopt casting manipulation and visual-based feedback control. Casting manipulation is a technique to deploy a robotic end-effector far from the robot's base, by throwing the end-effector and controllin...

A study was conducted to measure the variation in propellant properties for three consecutive batches of an identical formulation. A secondary study was performed to assess the effect of casting vacuum on propellant density, hardness, mechanical properties and burn rate. Only small differences in properties between batches were evident and most were assessed as being within the uncertainty of t...

3D mili-scale channel representing simplified anatomical models of blood vessels were constructed in polidimethylsiloxane (PDMS). The objective was to obtain a sequential method to fabricate transparent PDMS models from a mold produced by rapid prototyping. For this purpose, two types of casting methods were compared, a known lost-wax casting method and a casting method using sucrose. The chann...

For steel castings produced in sand moulds, the expansion of the sand and have a significant impact on the final size and shape of the casting. Experiments are conducted using a cylindrical casting to study this effect for different sands (silica and zircon) and different sand binder systems (phenolic urethane and sodium silicate). The type of sand has a significant effect on the final casting ...
