The modified glassy carbon electrode (GCE) was prepared with 6-amino-4-(3,4-dihydroxyphenyl)-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (pyrazole derivative (AMPC)) and functionalized multi-walled carbon nanotubes. In this research, electrocatalytic activity of nanocomposite (AMPC/MWCNTs) has been studied by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoa...

We describe an approach for the simultaneous determination of isoenzymes of alkaline phosphatase (EC 3.1.3.1) based on the kinetic behavior of inhibition reactions. Data for absorbance vs time, collected while enzymes are being inhibited, are fitted with suitable models to obtain results related to activities of the individual isoenzymes. The primary focus is on two-component mixtures of the bo...

BACKGROUND The thermal decomposition of cephalexine, cefadroxil and cefoperazone under non-isothermal conditions using the TG, respectively DSC methods, was studied. In case of TG, a hyphenated technique, including EGA, was used. RESULTS The kinetic analysis was performed using the TG and DSC data in air for the first step of cephalosporin's decomposition at four heating rates. The both TG an...

This paper examines methods to test one- and two-dimensional histograms for several features including the renewal properties, detailed balance violations, and experimental condition dependences. The tests are simple to implement and allow rigorous statistical determination of the existence of these kinetic features. The tests are used to determine the lower bound on the number of measurements ...

the net analyte signal standard addition method was used for simultaneous spectrophotometric determination of sertraline and fluoxetine in pharmaceutical preparations. the method combines the advantages of the standard addition method with the net analyte signal concept to enable the extraction of information about an analyte from the spectra of multi-component mixtures. this method uses full s...

Eighty-three patients with various neuro-ophthalmic diseases were submitted to a standard automated protocol including kinetic and static perimetry The kinetic protocol included one peripheral, one intermediate and one central isopter and a blind spot contour determination The static protocol included fast thresholding of 80 points within the pericentral field and a 4-2-2-2 foveolar threshold d...
