UV derivative spectrophotometric study of the photochemical degradation of nisoldipine
(Il Farmaco, 2000)
The photodecomposition of nisoldipine ((+/-)3-isobutyl-5-methyl-1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-pyridine-3,5-dicarboxylate), whereby its 4-(2-nitrosophenyl) pyridine analogue is obtained as the photolytic product, ...
Bioavailability and possible benefits of wheat intake naturally enriched with selenium and its products
(Biological Trace Element Research, 2000)
Bioavailability and possible benefits of wheat intake naturally enriched with selenium and its products was tested. Wheat obtained by application of an original combination and procedure for foliar supplementation of plants ...
Femtosecond spectrally dispersed three-pulse four-wave mixing: the role of sequence and chirp in controlling intramolecular dynamics
(Journal of Raman Spectroscopy, 2000)
The roles of pulse sequence and pulse chirp were explored using femtosecond three-pulse four-wave mixing (FWM), The experiments were carried out on gas-phase It and the degenerate laser pulses are resonant with the transition ...
X-ray photoelectron study of the interaction of the uranyl group UO22+ with hydroxylapatite and fluoroapatite in aqueous solutions
(Journal of Structural Chemistry, 2000)
The interaction of the uranyl group UO22+ in aqueous solutions with hydroxylapatite and fluoroapatite was studied by X-ray photoelectron spectroscopy. The apatite samples under study were found to contain CO32- groups. The ...
Influence of lanolin and white soft paraffin on the determination of vitamin A in fats
(Spectroscopy Letters, 2000)
Pharmaceutical interaction of the most frequently used substances with fats: lanolin, white soft paraffin and vitamin A palmitate was studied. The mixtures were examined by TLC with different ratios of lanolin and vitamin ...
Distribution of HCV genotypes among risk groups in Serbia
(European Journal of Epidemiology, 2000)
Blood samples from 190 patients that were anti-hepatitis C virus (HCV) positive were genotyped and 165 were found to contain HCV-RNA. Genotyping was performed by PCR based on type-specific primers (117 isolates) and LiPA ...
Solution equilibria and characterization of the complex formed between hippuric acid and tin(II)
(Main Group Metal Chemistry, 2000)
The complex formation equilibria in tin(II) - hippuric acid (Hhip) solutions were investigated by potentiometric glass electrode measurements in 1.0 mol/L NaCl ionic medium at 298 K. Non-linear least-squares analysts of ...
A frequency stabilized waveguide CO2-laser for photoacoustic spectroscopy of gases
(Journal of the Serbian Chemical Society, 2000)
A theoretical model of a waveguide CO2-laser was made to optimize the dimensions of the waveguide tube and resonator, i.e., to obtain the best mode structure while maximizing the output power. The results were used to ...
Corrosion behaviour of epoxy coatings electrodeposited on galvanized steel and steel modified by Zn-Ni alloys
(Progress in Organic Coatings, 2000)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on hot-dip galvanized steel and steel modified by Zn-Ni alloys were investigated during exposure to 3% NaCl solution. ...
Spectrophotometric investigations of the reaction between gold(III) and potassium iodide
(Journal of the Serbian Chemical Society, 2000)
The equilibria of the complex formation between AuCl4-n(OH)(n)(-) and I- was studied spectrophotometrically in aqueous solutions containing KI:Au(III)less than or equal to 2 in the acidity range from 1 M HCl to pH 7 at 25 ...
