Amorphous silicon thin films, fabricated by thermal conversion of neopentasilane, were used to passivate crystalline silicon surfaces. The conversion is investigated using X-ray and constant-final-state-yield photoelectron spectroscopy, and minority charge carrier lifetime spectroscopy. Liquid processed amorphous silicon exhibits high Urbach energies from 90 to 120 meV and 200 meV lower optical...

Blackbody levels of emission in the electron cyclotron range of frequencies have been observed from an overdense (vpe;3vce) Madison Symmetric Torus @Dexter et al., Fusion Technol. 19, 131 ~1991!# reversed field pinch plasma, a result of electrostatic electron Bernstein waves emitted from the core and mode converted into electromagnetic waves at the extreme plasma edge. Comparison of the measure...

The hypothalamo-pituitary-adrenal axis has been assessed in 17 asthmatic children before and after long-term prednisolone therapy was changed to daily corticotrophin. In 14 of the 17 children the plasma corticosteroid concentration exceeded 15 mug/100 ml within five days of starting corticotrophin. No exacerbation of asthmatic symptoms occurred during conversion. The plasma corticosteroid respo...

We have recently shown that in a highly magnetized neutron star atmospheric plasma, vacuum polarization can induce resonant conversion of photon polarization modes via a mechanism analogous to MSW neutrino oscillation. In a recent paper Ozel has dismissed this mode conversion effect as " mistakes ". Here we explain why our arguments/calculations of this effect are correct.

Amiodarone is effective for long-term maintenance of sinus rhythm after electrical cardioversion of refractory atrial fibrillation or flutter. To examine its efficacy and safety for pharmacologic conversion of these arrhythmias, we studied 129 patients with refractory atrial fibrillation or flutter who had failed previous intensive conventional antiarrhythmic treatment. In anticipation of elect...

In Framingham cohort study, C-reactive protein was not associated with incident atrial fibrillation (AF) after adjustment for left atrial size. This study examined whether levels of plasma inflammatory markers would be significant risk factors for failed maze procedure for AF. This study enrolled 88 patients with mitral valve disease undergoing valve surgery (n=32, sinus control group) or conco...

The importance of non-prothrombin plasma and serum constituents in the physiological conversion of prothrombin to thrombin has been recognized only recently. A hemorrhagic disorder, called "parahemophilia" (Owren's disease), is associated with an elevated prothrombin time attributable to deficiency of a plasma component termed "Factor V" (1, 2). Inadequacy of plasma Ac-globulin, required for ra...

During the third trimester of human pregnancy the concentrations of deoxycorticosterone (DOC) in maternal plasma are 4-50 times those in nonpregnant women and men. It has been suggested that the increased amount of DOC in maternal plasma originates in the fetal compartment. We considered an alternate explanation for the high levels of DOC in plasma or near-term pregnant women, viz., that DOC ma...

and 0.03 6 0.1 mg/L for the low range (,1 mg/L). We conclude that citrated and heparinized plasma are equivalent specimens for D-Dimer testing with Tinaquant. For harmonization of D-Dimer concentrations between citrate and heparin plasma, a conversion factor of 0.84 for heparin plasma is recommended. The use of heparinized plasma allows measurements of chemical constituents as well as D-Dimer f...

By RICHARD WARREN, M.D. AND JOHN S. BELKO, M.S. A PRACTICAL CLINICAL METHOD for determining the activity in plasma of the accelerators of prothrombin conversion has not been so rapidly forthcoming as have been descriptions of their properties and reactions. Those methods which have been described have employed two general principles. The first. of these is the ability of the unknow’n plasma to ...
