Background: Bacteremia due to Enterococcus faecalis is usually caused by strains resistant to most antibiotics. Effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. The aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococc...

The kinetic of conjugated reactions of S-oxidation and perhydrolysis of phenoxymethylpenicillin with potassium hydrogenperoxomonosulfate in alkaline medium has been studied by the light absorbance increase of a forming product at 269 nm. The procedure of the quantitative analysis of phenoxymethylpenicillin in powder and drug by the kinetic spectrophotometric method is elaborated using triple po...

194 CLINICAL CHEMISTRY, Vol. 25, No. 1, 1979 gas chromatography before and after acid (6 mol/L HC1) and alkaline (NaOH) hydrolysis. We frequently observe a peak in the lactic acid position after alkaline hydrolysis. After acid hydrolysis of the same urine no lactate isobserved, but a peak appears in the position of levulinic acid. The mass spectra of these two peaks were identical with those of...

The combustion process begins with the ignition of fuel - bringing it to auto-ignition temperature, which is one important components kinetic characteristics fuel.
 Fuel does not occur immediately but after a certain period, during activation energy accumulated: heat or active centers, depending on mechanism thermal-kinetic chain-kinetic, sufficient overcome potential barrier. At same time...
