the lack of complete understanding of the substrate effects on carbon nanotubes (cnts) growth poses a lot oftechnical challenges. here, we report the direct growth of nanostructures such as the cnts on stainless steel 304and brass substrates using thermal chemical vapor deposition (tcvd) process with c2h2 gas as carbon sourceand hydrogen as supporting gas mixed in ar gas flow. we used an especi...

Abstract Laser cutting of copper-based alloy sheets is very difficult due to their high reflectivity, which can be modified with graphitization. The optimal parameters for a 2.5 mm thick brass sheet were determined by examining the laser beam parameter variations and cut kerfs. best characteristics kerfs obtained when surface was graphitized, frequency 200 Hz, applied speed 1400mm/min on 2500 W...

BACKGROUND Embouchure dystonia is a focal task-specific dystonia affecting the complex interplay of lower facial, jaw, and tongue muscles in musicians playing brass or woodwind instruments. Although it is highly disabling for affected patients, little is known about the pathophysiologic basis of this rare movement disorder. METHODS We therefore studied sensorimotor activation patterns during ...

The main objective to introduce the ABS (Acryonitrile Butadyne Styrene) plastic substrate in place of RTDuroid substrate for microstrip filters is to reduce the cost. The cost of plated ABS plastic substrate is substantially less (Rs. 4/sq.inch) compared to the cost of RT-Duroid (US$ 02/-/sq.inch). Two microstrip (hairpin line) band pass filters at 1537.5 MHZ and 1575.42 MHz have been developed...
