This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...

BACKGROUND Facial reticular blue veins are of esthetic concern. Most often these veins develop on the lower lids. The safest and most effective way of treatment is by vascular lasers. CASE REPORT We report on a successful reticular vein treatment using a long-pulsed 1064 nm Nd: YAG laser. We present a follow-up of 8 years with constant esthetic improvement without unwanted adverse events. C...

STUDY OBJECTIVE To evaluate the cost effectiveness of the Nd-YAG laser and bronchoscopic electrocautery for palliation in patients with symptomatic tumor obstruction. DESIGN A retrospective study. SETTING Bronchoscopy unit of a university hospital. PATIENTS AND INTERVENTION Thirty-one consecutive patients with inoperable non-small cell lung cancer and symptomatic intraluminal tumor underw...

Graphene oxide was prepared using modified Hummers method. Stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. Nd: YAG pulsed laser was applied to prepare reduced nanofluids. Experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (GO) in ethylene glycol. The enhancement ratio of...
