OBJECTIVE This study aimed to compare skeletal, dentoalveolar and soft tissue characteristics in white and black Brazilian subjects presenting normal occlusions. MATERIAL AND METHODS The sample comprised the lateral cephalograms of 106 untreated Brazilian subjects with normal occlusion, divided into two groups: Group 1- 50 white subjects (25 of each gender), at a mean age of 13.17 years (stan...

Thin, flexible silicon crystals are starting up applications such as light-weighted flexible solar cells, SOI, flexible IC chips, 3D ICs imagers and 3D CMOS imagers on the demand of high performance with low cost. Kerfless wafering technology by direct conversion of source gases into mono-crystalline wafers on reusable substrates is highly cost-effective and feedstock-effective route to cheap w...

OBJECTIVE The purpose of the modified repositioning appliance was to overcome the shortcoming of existing design for repositioning protruded premaxilla in a child with bilateral cleft lip and palate. METHODS The basic principles of design were similar to Latham's appliance but the surgical pinning of premaxillary segment was avoided and instead acrylic splint was prepared. CONCLUSIONS This ...

This paper introduces a displacement mapping algorithm that represents protruded shapes on the surface of an object. Two verticalsurfaces that are perpendicular to the underlying surface are added along the boundary of the polygon surface in order to represent pixels overflowing acrossthe boundary of the polygon surface. The proposed approach can accurately represent the silhouettes of protrude...

A series of 14 patients with a protruded thoracic intervertebral disc is reported. We believe that the true incidence may be as high as one patient per million population per annum. Trauma, sometimes mild, seems to have played a significant role in this series. This fact coupled with pronounced numbness and disagreeable paraesthesiae should suggest the diagnosis with thoracic spinal lesions. Ar...

At 3 a.m. 01116th ultimo a woman was brought to the dispensary by the Police from a village some 25 miles away.
