In orthodontics there has been a change in the treatment plan of crowding cases from extraction protocol. This was mainly due to introduction self-ligating bracket and temperature activated wires. Even though are certain exceptions, have evolved because its advantages such as low friction, shorter duration increased efficacy. Damon’s system existence since 1930 but it well developed past 30 yea...

This paper addresses the task of nuisance reduction in twowire speaker recognition applications. Besides channel mismatch, two-wire conversations are contaminated by extraneous speakers which represent an additional source of noise in the supervector domain. It is shown that two-wire nuisance manifests itself as undesirable directions in the interspeaker subspace. For this purpose, we derive tw...

OBJECTIVES To investigate the reproducibility of wire codes to characterise residential power line configurations and to determine the extent to which wire codes provide a proxy measure of residential magnetic field strength in a case-control study of childhood leukaemia conducted in nine states within the United States. METHODS Misclassification of wire codes was assessed with independent me...

a 3-year-old arabian colt was presented for a major gingiva wound at the right rostral part of mandible. after clinical assessments, rostral mandibular fracture was determined. stabilization of fractured region was achieved via cerclage wire application under general anesthesia. fixation wires were left in place for 6 weeks. a 3 -month follow up revealed complete fracture healing. the purpose o...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

When the self-ligating brackets were introduced the scope was first and foremost to facilitate the daily work for the orthodontist and their staff members. The development within fixed appliances had focused on other aspect of the facilitation by the introduction of prescription brackets making first , second and third order bend superfluous and although there was a pronounced difference betwee...

The medial axis transform is valuable for shape representation as it is complete and captures part structure. However, its exact computation for arbitrary 3D models is not feasible. We introduce a novel algorithm to approximate the medial axis of a polyhedron with a dense set of medial points, with a guarantee that each medial point is within a specified tolerance from the medial axis. Given th...

In this paper we present a new environment for supporting Web user interface migration through different modalities. The goal is to furnish user interfaces that are able to migrate across different devices offering different interaction modalities, in such a way as to support task continuity for the mobile user. This is obtained through a number of transformations that exploit logical descripti...
