One of the main reasons for continuing interest in shock focusing is its ability to concentrate energy in a small volume and produce extreme temperatures and pressures in fluids in a controlled laboratory environment. The phenomenon of shock wave focusing leading to extreme conditions in fluids during micro- and nanosecond...

ABSTRACT
A comprehensive study has been made on the dynamical process taking place in the laser-plasma generation i.nduced by a TEA CO2 laser bombardment on metal target and non-metal target Eom low to high pressures surrounding gas. ln the case of metal target, pure zinc plate was used as a target...

Extracorporeal Shock Wave Lithotripsy (ESWL) merupakan terapi non-invasif yang menjadi tatalaksana lini pertama batu ureter. Terdapat berbagai faktor yang diduga dapat mempengaruhi tingkat keberhasilan ESWL, diantaranya lokasi batu dan ukuran batu ureter. Penelitian ini bertujuan untuk membuktikan adanya hubungan antara lokasi batu dan ukuran batu dengan tingkat keberhasilan ESWL pada...

A special interferometric technique with high sensitivity has been devised on the basis of rainbows refractometer without the use of an additional and delicate amplitude-splitting setup. This new technique was use for the characterization of shock wave plasma induced by a Q-sw Nd-YAG laser on various kinds of metal samples...

In spite of abundant experimental evidences supporting the viability of the laser induced shock wave plasma model for the explanation of the important features ofthe plasma and the associated spectroscopic characteristics, a controversy on the atomic excitation mechanism in the plasma has remained to be completely resolved. In this study...

Baground: the optimal management of lower calyceal stones is still controversial, because no single method is suitable for the removal of all lower calyceal stones. Minimally invasive procedures such as extracorporeal shock wave lithotrispy (ESWL), percutaneous nephrolithotomy (PNCL) and flexible ureteroscopy (fURS) are the therapautic methods for lower calyceal stones....

Laser Nd-YAG dengan energi 26 mj dan 53 mj, lebar pulsa 8ns di/Okla/can ke target (Cu) pada tekanan udara yang dikurangi. Peningkatan rasio sinyal latar belakang (S/B) dimungkinkan dengan kombinasi unik dari plasma yang dibatasi (confined plasma) dan teknik pencitraan (imaging technique). Dengan menggunakan teknik pencitraan, plasma primer (primary plasma)...
