one common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. different methods have been used to prevent demineralization such as fluoride therapy and application of sealant to prevent caries. the recent effort to improve the resistance against the demineralization ...
In this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. We prove a posteriori $ L^2(L^2)$ and error estimates for this method under minimal regularity hypothesis. Test problem of an application of the wave equation in the laser is presented to verify the efficiency and accuracy of the method.
The non-continuous laser beam in pulsed lasers allows the mechanical peening between two consecutive beams on a still hot weld bead. At a very short time (20, 150 and 300 ms) after laser pulse application, mechanical peening was performed on the welding bead. To achieve these short times, the light sensor detects the nth laser pulse and the mechanical arm starts moving. Upon reaching the tip of...
background: acupuncture is an indispensable part of traditional chinese medicine for relief of pain. the purpose of this study was the immediate & latent of low power laser ga-al-as irradiation applied to acupuncture points on experimental pain threshold. methods: this quasi-experimental study was conducted on seventy adult women ranging from 20 to 40 years old assigned randomly into two groups...
