BACKGROUND The Ponseti method of congenital idiopathic clubfoot correction has traditionally specified plaster of Paris (POP) as the cast material of choice; however, there are negative aspects to using POP. We sought to determine the influence of cast material (POP v. semirigid fibreglass [SRF]) on clubfoot correction using the Ponseti method. METHODS Patients were randomized to POP or SRF b...

Pure whey protein isolate (WPI)-based cast films are very brittle due to its strong formation of protein cross-linking of disulphide bonding, hydrogen bonding as well as hydrophobic and electrostatic interactions. However, this strong cross-linking is the reason for its final barrier performance. To overcome film brittleness of whey protein layers, plasticisers like glycerol are used. It reduce...

This paper addresses a basic security requirement of electronic voting, namely that a voter can correct or abort his vote at any time prior to his final vote casting. This requirement serves as a protection against voter precipitance (haste). We specify rules for a reset and cancel function that implement the correction and abort requirement. These rules are integrated in an extended version of...

background numerous factors have an effect on the accuracy of an impression and resultant cast, and these include: impression material, impression technique, tray selection, impression disinfection, storage time of impression before pouring, stone type used for fabrication of cast. up to now, there has been little research conducted on the effect of contact time of a cast with an impression, on...

BACKGROUND The use of an oscillating saw for cast removal creates a potential for iatrogenic injury and patient discomfort. Burns and abrasions can occur from the heat created by frictional forces and direct blade contact. With use of a cadaver model system, skin temperature measurements were recorded during cast removal with an oscillating saw. METHODS Casts of uniform thickness were applied...

OBJECTIVE The shear bond strengths of two hard chairside reline resin materials and an auto-polymerizing denture base resin material to cast Ti and a Co-Cr alloy treated using four conditioning methods were investigated. MATERIAL AND METHODS Disk specimens (diameter 10 mm and thickness 2.5 mm) were cast from pure Ti and Co-Cr alloy. The specimens were wet-ground to a final surface finish of 6...

In this paper, I ask whether educational value is determined in any way by intrinsic value. The aim of the paper to explore appeals an activity or state affairs can justify proposed turn Korsgaard's work on concept cast light relationship between and Korsgaard claims that often held distinction instrumental conflates two separate distinctions. These are intrinsic/extrinsic final/instrumental di...

Introduction Loss of an auricle may be due to congenital disease, trauma, or surgical removal of benign or malignant tumors. Auricular defects can be repaired, or reconstructed with autogenous tissue, but this may be unsuitable in many situations. Additionally the use of autogenous tissues requires harvesting a graft there by adding a surgical site. A good alternative is to develop an auricular...
