Laser is one of the sources that induce a biological effect in higher plants. The positive effect of laser on some crops has been proved. This research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (Triticum aestivum cv. Kavir) under different NaCl treatment levels. Semi-coherent red beam, infrared beam and one-second harmonics of Neodymiu...

introduction: laser-assisted vaporization of prostate tissue by means of the potassiumtitanyl- phosphate (ktp) laser is in clinical use. alternative laser sources are available but are lacking clinical experience.the 980 nm wavelength diode laser provides good hemostasis, in addition to a more rapid ablation rate. the aim of this study is approving the capability, feasibility, and good post-ope...

This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...

Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...

low-intensity laser therapy (lilt) is defined to supply direct biostimulative light energy to the cells. while several studies have demonstrated that lilt has stimulating effects on bone cells and can accelerate the repair process of the bone, others reported delayed fracture healing or no effects after lilt. the aim of this article was to review the studies evaluating the biomodulation effects...

used in conjunction with or as a replacement for traditional methods, it is expected that specific laser technologies will become an essential component of contemporary dental practice over the next decade. the current review is designed to focus on the acid resistance of laser application and tries to introduce laser settings capable to achieve this feature for clinical application. applicatio...
