In this study, a derivative method is applied for the determination of dye concentration in fabrics dyed with tricomponent dye mixtures. The reflectance of spectra of the samples were recorded between 400 and 700 nm. Initially, the obtained (K/S) spectra were divided by the spectrum of a standard sample dyed with two of the components in the ternary mixture and the derivative spectra were calcu...

This study uses the gravity method to assess characteristics of Manna segment fault, a part Sumatran fault. research aims contribute existing knowledge by providing additional insights into fault's characteristics, which is essential for future disaster mitigation efforts. The fault geographically situated between coordinates 4.4⁰S - 3.9⁰ S and 102.7⁰ E – 103.2⁰ E, making this area prone earthq...

The analytical signal method and its derivatives can be explicitly calculated assessed for analyzing estimating the boundary of geological structures, such as faults or dikes, from potential field anomalies. Gravity east Qeshm Island north coast Sarkhun to Latidan in SE Iran has been measured one-kilometer regular network. regional anomaly effects are deducted Bouguer anomaly, where it get resi...

two sensitive spectrophotometric methods are presented for the assay of repaglinide in bulkdrug and in formulations using methyl orange, as reagents. oxidant by reacting with a fixedamount of either methyl orange and measuring the absorbance at 485.2 nm (method-i) andmeasuring the absorbance at 618.9 nm (method-ii). developed method is based on the formationof extractable colored complex of dru...

The symmetry of floating drops is considered. Under conditions that the free boundary is flat it is shown that all three component interfaces are symmetric about a vertical line.
