Metal surface flaws on can be detected using the frequency transmission characteristics of surface acoustic waves (SAW). In addition, noncontact, remote detection can be made possible by using laser ultrasound. So far, broadband SAW generated by a single generation laser has been used for surface flaw detection[1]. Results have shown that the SAW transmitted across a slit of depth 0.5 mm showed...

The International Journal of Health Policy and Management (IJHPM) is a new journal that aims to stimulate not only inter-disciplinary research relating to health, but even an entire new generation of such journals. The challenges of improving human health worldwide clearly suggest ‘why’ such a journal is needed, but ‘how’ bridges and junctions across fields of study towards this end might be fo...

During the spread of pandemic disease, dental practice come across highest risk corona virus infection by exposure from patient saliva, aerosols generation during procedure, blood contamination oral surgical procedure. This can be transmitted symptomatic to asymptomatic individual through aerosol spread, saliva contamination. Due its ability airborne transmission, so generated natural activity ...
