absorbance

rosea were compared with each other in terms of morphology, size distribution, solubility, UV/visible absorbance behavior, and antidiabetic activity.

DPPH radical-scavenging activity (%) = [1 (As1As2)/As0] x 100, where As0 is the absorbance of the control (distilled water instead of sample); As1 is the absorbance of a mixture of DPPH solution with sample and As2 is the absorbance of the sample alone (methanol instead of DPPH-methanol solution).

The absorbance signals of Sb (III) were high and less volatile in the range of 1.0-6.0.

Devices with highest dye absorbance on solid titania films show highest short-circuit current and open-circuit voltage, corresponding with 3.72% of device efficiency (Figure 2(a) and see (a) in Table 1).

Maximum absorbance was obtained at 50 mM as shown in Figure 3(b).

After addition of 0.6 ml hydrogen peroxide solution, tubes were vortexed and absorbance of the hydrogen peroxide at 230 nm was determined after 10 min, against a blank.

Staphylococcus aureus showed good and complete absorbance activity after 24 h, at pH 6, 7 and 8.

The formation constant ([K.sub.f]) and the molar absorptivity ([epsilon]) of the resulting complexes between ligands and different cations were calculated by fitting the observed absorbance, [A.sub.obs], at various [[M.sup.2+]] / [L] mole ratios to the previously derived equation (equation 1 and 2), which express the [A.sub.obs] as a function of the free and complexed metal ions, and the formation constant evaluated from a non--linear least--squares program KINFIT [17].

Absorbance Measurement by Fabricated Fiber Optic Microchannel.

Absorbance spectroscopy is an essential measurement tool for the measurement and analysis of proteins [1] and nucleic acids [2].

The absorbance was measured at 517 nm against a blank group.

The absorbance of the complex was measured at 510 nm by spectrophotometer.
