Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...

BACKGROUND The optimal site for local anesthetic placement during ultrasound-guided infraclavicular block remains controversial. METHODS Patients were randomized to receive lidocaine 2% 30 mL as a single injection posterior to the axillary artery (n = 51) or a triple injection ideally adjacent to each brachial plexus cord (n = 49). Pinprick sensory and motor block (3 = no block, 0 = complete ...

We report on the "rst lasing of a high-gain harmonic generation (HGHG) free-electron laser (FEL). The experiment was conducted at the Accelerator Test Facility (ATF) at Brookhaven National Laboratory (BNL). This is a BNL experiment in collaboration with the Advanced Photon Source (APS) at Argonne National Laboratory. A preliminary measurement gives a high-gain harmonic generation (HGHG) pulse e...

conclusions patients receiving a cpvb in addition to tpvb after ldf reconstruction experienced similar pain to those receiving tpvb alone. a larger, randomized clinical trial is warranted to fully determine the benefits of using cpvb in addition to tpvb for this procedure. results a total of 22 patients were included in this study (11-cpvb and 11-tpvb). the mean nrs pain score of cpvb patients ...

Ellis-van Creveld syndrome is transmitted as an autosomal recessive trait. This syndrome is accompanied in 60% of cases with congenital heart disease, mostly single atrium or large ASD. Patients are mostly symptomatic, but in this rare case despite 68 years of age, the patient was free of symptoms except for complete heart block for which pacemaker was inserted
