The laser scalpel and the laser coagulator are representative in laser medicine. However the biostimulative effect of laser with low power is getting the focus of attention, since acceleration of wound healing has been proved by laser radiation. Recently laser acupuncture was initiated as an unique therapeutic application in Europe and China. In Japan the authors have developed YAG laser acupun...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
The purpose of this study were to 1) demonstrate the effect of infrared laser radiation on the sensory nerve latency of peripheral nerve, and 2) determine temperature changes in the tissue surrounding of the treated area. Fifty health subjects without an history of right and left upper extremity pathological conditions were divided into two groups: laser (n=30) and placebo (n=20) groups. Six 1 ...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...
The induced flow effect is the rotary motion generated in the fluid flow due to the temperature gradient. The phenomenon of thermophoresis is the movement of particles from the warmer side of the fluid to the cooler side. Laser is a very suitable device for creating a temperature gradient due to its unique features such as high power density, harmonic waves, single wavelength and very low diver...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
introduction: the aim of this study was to evaluate the effect of various concentrations of naocl on shear bond strength of composite resin to dentin of primary teeth, prepared with laser and bur. methods: in this in vitro study, 48 primary molars were sectioned at mesiodistal direction and were randomly divided into 6 groups; g1: bur, g2: bur + naocl 2.5%, g3: bur + naocl 5.25%, g4: laser, g5:...
