A novel approach has been developed for the quantification of total mechanical power output produced by an isolated, well-defined muscle group during dynamic exercise in humans at different contraction frequencies. The calculation of total power output comprises the external power delivered to the ergometer (i.e., the external power output setting of the ergometer) and the "internal" power gene...
Matrix formulations of Eudragit E 100: NE 40D polymers (100:0, 70:30, 60:40, 50:50% w/w) with 20% w/w of triacetine and 5% w/w of atenolol were prepared by film casting method with different solvents (methanol, 2-propanol and acetone). In vitro release of atenolol from the films were studied by vertical Franz diffusion cells in HEPES buffer (pH 7.4) for 78 h. Direct currents of 0.1 and 0.5 mA/c...
introduction: the purpose of this study was to evaluate amalgam surfaces treated by different output powers of erbium-doped yttrium aluminum garnet (er:yag) laser by scanning electron microscope (sem). methods: twenty-one amalgam blocks (8 mm × 8 mm, 3 mm thickness) were prepared by condensing silver amalgam (into putty impression material. after keeping them for 24 hours in distilled water, th...
