In this research, microstructure and mechanical properties of laser welded joints between 2304 duplex stainless steel and Inconel 718 nickel-based super alloy were investigated. Microstructural evolution in the various areas of welded joints and also the effect of welding parameters on the mechanical properties of dissimilar joints were studied. Response surface methodology based on the central...
BACKGROUND Liposuction is a type of aesthetic surgery that has been performed on humans for decades. There is not much literature addressing the subject matter of pre- and post-surgery blood parameters, although this information is rather interesting. Documentation on patients who received laser-assisted liposuction treatment is particularly scarce. Until now, there has been no literature showi...
The purpose of this pilot study was to evaluate periodontal tissue repair after CO2 laser applications in the treatment of severe periodontal defects. Five patients, three men and two women, age range 37 to 55 years, were enrolled. All of the participants in the study were in good general health and presented with at least one tooth with PD of 6 to 9 mm and bleeding on probing. At baseline, all...
Nowadays in highly competitive precision industries, the micromachining of advanced engineering materials is extremely demand as it has extensive application in the fields of automobile, electronic, biomedical and aerospace engineering. The present work addresses the modeling and optimization study on dimensional deviations of square-shaped microgroove in laser micromachining of aluminum oxide ...
Background: Laser surgery and radiotherapy are commonly used to treat glottic cancer. Objective of Review: To compare outcomes and cost of laser surgery versus radiotherapy for T1–T2N0 glottic cancer. Type of Review: Meta-analysis. Search Strategy: The Cochrane Central Register of Controlled Trials, Ovid MEDLINE In-Process & Other NonIndexed Citations, Embase, Web of Science (1990–2010) were se...

The objective of the present study was to evaluate changes in optic nerve head parameters, measured by confocal laser tomography, before and after trabeculectomy in order to identify outcome measures for the management of glaucoma. The optic nerve head of 22 eyes (22 patients) was analyzed by confocal laser tomography with the Heidelberg retinal tomogram (HRT) before and after trabeculectomy. T...
introduction: carpal tunnel syndrome (cts) is the most common type of entrapment neuropathy. conservative therapy is usually considered as the first step in the management of cts. low level laser therapy (lllt) is among the new physical modalities, which has shown therapeutic effects in cts. the aim of the present study was to compare the effects of applying laser and splinting together with sp...
In the present study, the optimization of pulsed Nd:YAG laser welding parameters was done on a lap-joint of a 316L stainless steel foil in order to predict the weld geometry through response surface methodology. For this purpose, the effects of laser power, pulse duration, and frequency were investigated. By presenting a second-order polynomial, the above-mentioned statistical method was manage...
