the effect of low intensity laser radiation in the treatment of acute and chronic pain is now established in many studies. trigeminal neuralgia is a pain passes through nerve’s branches and its trigger is located in skin or mucosa that could lead to pain with a trigger stimulus. the pain involved branches of trigeminal nerve that sometimes has patients to seek the treatment for several years. n...

background: neuropathic pain (np) is a serious suffering medical condition that frequently leads to disability and life style changes. although the exact mechanisms of np are still unknown, recently the role of reactive oxygen species (ros) reported as an important factor for np. apoptosis, increase of atp production and reduction of antioxidants are also the other factors influencing in np. th...

Title of Document: VARIABILITY OF THE GREAT PLAINS LOW-LEVEL JET: LARGE SCALE CIRCULATION CONTEXT AND HYDROCLIMATE IMPACTS Scott J. Weaver, Doctor of Philosophy, 2007 Directed By: Professor Sumant Nigam, Department of Atmospheric and Oceanic Science Variability of the Great Plains Low-Level Jet (GPLLJ) is analyzed from the perspective of larger-scale, lower-frequency influences and regional hyd...

low-level laser therapy (lllt) provides several benefits for patients receiving orthodontic treatment. according to some literatures, orthodontic tooth movement (otm) can be enhanced but some investigators have reported contradictory results. this article reviews the literature regarding the different aspects of the use of lllt on otm and its alterations. the general data regarding the study de...

introduction: tonsillectomy is among commonest otorhinolaryngologic surgeries. many methods have been used to control post surgical pain, but despite it, pain is still one of the problems related to this operation. recently, due to the non invasiveness of low level lasers, this modality has attracted attention. the purpose of this study is to evaluate the effects of low level laser irradiation ...

In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...

We propose a dynamic hedging strategy for jet fuel which strikes a balance between hedging against jumps in the price of jet fuel and placing bets that the price will rise, lowering the overall cost of jet fuel. We model the commodity price using an unobservable two-factor model that allows mean-reversion in short-term prices and uncertainty in the equilibrium level to which prices revert. We c...

radiotherapy in the head and neck region and chemotherapy might give rise to oral mucositis which is a severe and painful inflammation. there is no known definite cure for mucositis. a number of studies have attempted to evaluate the effect of low-power laser on radiotherapy- and chemotherapy-induced mucositis. the present study was undertaken to evaluate the effect of low-power laser on the pr...

A model of sound generated in an ideally expanded supersonic (Mach 2) jet is solved numerically. Two con gurations are considered; (i) a free jet and (ii) an installed jet with a nearby array of exible aircraft type panels. In the later case the panels vibrate in response to loading by sound from the jet and the full coupling between the panels and the jet is considered, accounting for panel re...
