BACKGROUND The symmetrical Lyon brace is a brace, usually used to maintain correction after a plaster cast reduction in the Cotrel's EDF (Elongation-Derotation-Flexion) frame. The new Lyon brace or ARTbrace is an immediate corrective brace based on some of the principles of the plaster cast which are improved due to advances in CAD/CAM technology. The aim of this paper is to describe concepts o...

One-hundred percent local plaster-based building materials were developed using Alfa (Stipa tenacissima L.) fibers from eastern Morocco region. Indeed, the incorporation of natural in is one promising approaches to design new bio-based and green sector. The present study concerns fabrication, investigation thermophysical properties energy saving potential Alfa-plasterboard for roofing applicati...

Owing to the insufficient converter heat, IF steel is produced via BOF–LF–RH–CC process in Pangang Group Xichang Steel and Vanadium Co., Ltd. To clarify evolution of inclusions control strategy improve cleanliness molten Ti-bearing long process, scanning electron microscopy with energy spectroscopy analysis automatic were employed analyze number, size, type morphology from RH tundish. The resul...

During continuous casting, argon blowing from tundish cover (ABTC) can greatly prevent the flow of remaining air and decrease reoxidation molten steel in tundish. In current study, a numerical model based on two-strand slab casting machine was established to investigate feasibility evaluate protective effect ABTC process. The influence operation parameters, including sealing schemes holes rate ...

Objective : We report here results obtained concerning the authenticity of Napoléon’s RUSI death mask Napoléon. Methods mtDNA analyses three hairs included in plaster inter eyebrowed region mask, and SEM-EDX plaster, pencil lead used for inscription are realized. Results is “plâtre de Paris” soft graphite. The studied showed presence 16184T mutation ; that confirms an authentic replicate original

background: human malaria remains a major malady in eastern iran. vector control interventions such as indoor residual spraying are used to fight with the disease. this study was undertaken to determine the lethal and residual effects of three different pyrethroid insecticides on adult mosquitoes of anopheles stephensi on different surfaces in iran, as part of a national program to monitor inse...

Measuring plaster models by hand is the traditional method of assessing malocclusion. Recent technologic advances now allow the models to be digitized, measured with software tools, stored electronically, and retrieved with a computer. OrthoCAD (Cadent, Fairview, NJ) performs this service. The purpose of this study was to evaluate the reliability of the OrthoCAD system. Two independent examiner...
