ontinuous-wave laser operation of bulk Er:Yb:phosphate glass pumped at 980 nm by an InGaAs index-guided diode laser has been achieved for the first time to our knowledge, with 2 mW of output power obtained at 1.54 microm. To optimize pumping conditions and to investigate the effects of pump wavelength, the Er(3+):Yb(3+) glass disk has also been pumped by a Ti:Al(2)O(3) laser at 960 and 980 nm, ...

We present results following from the coupled channel model of two a0 resonances decaying into the πη and KK mesons. The a0(980) resonance can be described by two distinct poles. It is shown that the discrepancy in the a0(980) mass position between the Crystal Barrel Collaboration and the E852 Group can be explained and removed. In our model with parameters fixed by the present experimental dat...

It is possible to increase the sampling resolution and the available information on zooplankton populations by applying acoustic sampling techniques. Knowledge of an organism’s acoustic target strength (TS) is critical for translating acoustic data into meaningful biological information, such as numerical abundance. We have taken several approaches to evaluate the acoustic TS of Mysis relicta, ...

introduction: the aim of the present in vitro study was to evaluate the disinfection ability of 980-nm diode laser in comparison with sodium hypochlorite (naocl) as a common root canal irrigant in canals infected with enterococcus faecalis ( e. faecalis ). methods and materials: the root canals of 18 extracted single-rooted premolars were prepared by rotary system. after decoronation, the roots...

1. The electrophysiological effects of CI-980, a new tubulin-binding agent that inhibits assembly of cytoplasmic microtubules, on transmembrane action potential characteristics were studied in right ventricular papillary muscles from guinea-pig hearts. 2. In papillary muscles driven at 1 Hz, CI-980 at concentrations > or = 10(-5) M produced a concentration-dependent increase in the maximum upst...

Co-amoxiclav is widely used in France to treat different infectious diseases, in particular community-acquired otitis, sinusitis and pneumonia, and occasionally urinary tract infections (UTIs). While the mechanisms of resistance to co-amoxiclav have been well defined, particularly in Escherchia coli, the influence of co-amoxiclav treatment on the in vivo selection of E. coli resistant to co-amo...

Bulk yttrium oxysulfide phosphors were prepared using the polysulfide flux method. The morphology and structure was characterized using transmission electron microscopy and x-ray powdered diffraction. Visible emissions occurring near 530 and 550 nm and 660 670 nm consistent with the H11/2, S3/2 → I15/2 and F9/2 → I15/2 transitions, respectively, were observed under 808, 980, and 1560 nm excitat...
