MnTiO3-Zeolite-Y nanocomposites were synthesized with 5-10-20% (w/w) of MnTiO3 by stearic acid gel method. Then, the gels were calcined at 900 °C for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. Also, the presence of rhombohedral phase of MnTiO3 in Zeolite-Y matrix was confirmed by XRD, SEM, EDX and BET. The VSM results showed t...

Recently, by reanalyzing the phase shift data of I = 0 ππ and of I = 1/2 Kπ scatterings, we showed the evidences for existence of light scalar mesons, σ(600) and κ(900), respectively, which had been sought but missing for a long time. The σ(600) and κ(900) together with the established resonances, a0(980) and f0(980), are shown to be consistently classified as the members of a single scalar σ-n...

BACKGROUND We explored a treatment simplification strategy to darunavir/ritonavir 900/100 mg once daily guided by the darunavir virtual inhibitory quotient (vIQ) in patients receiving salvage therapy with darunavir/ritonavir 600/100 mg twice daily. METHODS Open-label, randomized pilot study in HIV-infected patients on darunavir/ritonavir 600/100 mg twice daily (viral load <50 copies/ml; darun...

background and objective: multi-walled carbon nano tubes (mwcnts) as an important element of nanosciences have a remarkable absorption in the region of nir window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. to disperse mwcnts in water, it is proposed to attach carboxylated functional group (-cooh) to mwcnts in order to increase dispersivity in wate...

mntio3-zeolite-y nanocomposites were synthesized with 5-10-20% (w/w) of mntio3 by stearic acid gel method. then, the gels were calcined at 900 °c for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. also, the presence of rhombohedral phase of mntio3 in zeolite-y matrix was confirmed by xrd, sem, edx and bet. the vsm results showed the antiferromagnetic properties f...

In this study, Ti-22Al-25Nb intermetallic compound alloys are fabricated through selective laser melting (SLM) at four scanning speeds (600, 700, 800, and 900 mm/s). The microstructure mechanical properties of the systematically evaluated. results indicate that speed significantly affects characteristics (e.g., relative density, grain size, texture precipitation secondary phases). variation law...

BACKGROUND For patients undergoing percutaneous coronary intervention, the administration of a clopidogrel loading dose ranging from 300 to 600 mg is currently recommended. It is unknown, though, whether loading doses higher than 600 mg exert additional suppression of platelet function. METHODS AND RESULTS Sixty patients with suspected or documented coronary artery disease admitted to our hos...

This study uses a random effect panel model to examine the impact of CEO traits and compensation on earnings performance and financial leverage for the 729 listed US companies in ExecuComp over the period of 2001– 2010. The results indicate that CEO cash compensation has a negative relationship with earnings performance, but that it has a positive impact on financial leverage. Moreover, for CEO...

The empirical results derived from our fixed effects model provide no support for a linkage between a CEO's stock option grant and future firm risk. We find, using the panel corrected error term methods (PCSE) that control for the heteroscedasticity and autocorrelation, that current period stock option awards do have a positive effect on future firm risk. From the PCSE model we also find that t...
