background: the seminal plasma is an excellent source for noninvasive detection of spermatogenesis. the seminal plasma of normospermic and azoospermic men has been analyzed for detection of spermatogenesis. methods: optical spectroscopy (attenuated total reflectance-infrared spectroscopy (atr-ir) and fourier transform infrared spectroscopy (ft-ir) has been used to analyze the seminal plasma and...

Background Measurement of plasma metanephrines is regarded as one of the best screening tests for phaeochromocytoma/paraganglioma. Current guidelines recommend that samples are ideally collected in the supine position after 30 min rest and interpreted using supine reference ranges, in order to optimize the diagnostic performance of the test. Current practice in our centre is to collect samples ...

Experiments are reported in which two configurations for ablation-plasma-ion-implantation ~APII! are characterized by diagnostics and compared. The first configuration oriented the target parallel to the deposition substrate. This orientation yielded ion-beam-assisted deposition of thin films. A delay (.5 ms) between laser and high voltage was necessary for this geometry to avoid arcing between...

The presently available processing power in Generic Processing Units (GPU) combined with state-of-the-art programmable logic devices enables the implementation of complex algorithms for plasma diagnostics in a real-time scenario. A tomography diagnostic based on three linear pin-hole cameras each with eight lines of sight has been developed for the ISTTOK tokamak. The plasma emissivity in a pol...

TOWARDS A COMPLETE PLASMA DIAGNOSTIC SYSTEM by Dong Wu Zhao Doctor of Philosophy in Engineering-Electrical Engineering & Computer Sciences University of California at Berkeley Professor Costas J. Spanos, Chair We have set up a plasma diagnostic system with three sources of signals, OES, RF, and machine signals. CF2 OES lines 275 nm and 321 nm are found to be better than any other signals for po...

Polarized surface-enhanced Raman scattering (SERS) spectroscopy was applied for obtaining biochemical information about the seminal plasma. The effect of different laser polarizations (nonpolarized, linear-polarized, right-handed circularly polarized, and left-handed circularly polarized) on seminal plasma SERS spectroscopy was explored for the first time. The diagnostic performance in differen...
