Intravenous dexamethasone and diclofenac were evaluated in a double blind randomised trial, relative to an opioid (pentazocine) and placebo (saline), in 160 patients undergoing extraction of impacted lower third molar teeth. Test drugs were administered intravenously before surgery to provide postoperative analgesia. Following the operation, pain was assessed using a 10 cm visual analogue scale...

A method of machining the internal double-arc spiral bevel gear with a finger milling cutter was presented. The mathematical model tooth profile established considering principle by generating method, and three-dimensional (3D) graph developed. Subsequently, applying meshing theory, 3D alignment curve for established. Based on surface equation crown gear, intercept derived. divided into four cu...

Abstract To grasp thermal elastohydrodynamic lubrication (TEHL) characteristics of the conjugating tooth-pairs inclined double-roller enveloping hourglass worm drive in transmission process. The numerical solutions line contact EHL were obtained based on meshing theory this and EHL. TEHL solution is solved by using multigrid method, film pressure thickness are got at same time. effects roller r...

The most essential components in escort farming are the determination of airflow patterns and distribution impact microclimate temperature variables. objective this study is to use Computational Fluid Dynamics (CFD) models ascertain aerodynamic thermal dynamics protected agricultural greenhouses suitable for cultivation tropical Northeastern crops Thailand by defining differences greenhouse lay...

IntroductionTooth segmentation on cone-beam computed tomographic (CBCT) imaging is a labor-intensive task considering the limited contrast resolution and potential disturbance by various artifacts. Fully automated tooth cannot be achieved merely relying CBCT intensity variations. This study aimed to develop validate an artificial intelligence (AI)-driven tool for imaging.MethodsA total of 433 D...

Skiving is an efficient gear cutting technology with relatively high machining accuracy, especially for internal gears. Nevertheless, the accuracy can hardly be satisfied if skived modified, so we try to extend definition and hypotheses domain of previous works. In this paper, fundamental research conducted further improve skiving accuracy. Firstly, a new type tool double rake faces proposed fl...
