Arabinoxylans (AXs) – non-starch polysaccharides (NSPs) is one of the most discussed main components contained in all parts cereal plants. AXs combine bioactive and technological functions. As dietary fibres, they have physiologically beneficial properties for human health. are water-soluble insoluble water. The structure, quantity depend on which part grain or plant extracted method isolation ...

in a survey carried out to establish the incidence of erythrocyte glucose­ 6-phosphate-dehydrogenase deficiency, 738 professional blood donors of tehran were examined. the fluorescent spot technique was used for screening and qualitative determination of g-6-pd in erythrocytes. this technique was compared with other methods of g-6-pd enzyme assay and proved to be very reliable. qualitative enzy...

A better understanding of the physico-chemical principles underlying the formation of calculus has led to a need for more precise information on the chemical composition of stones. A combined qualitative and quantitative procedure for the chemical analysis of urinary calculi which is suitable for routine use is presented. The procedure involves five simple qualitative tests followed by the quan...

Experimental MS response factors were measured for 36 different saturated and unsaturated volatile organic compounds (VOC) containing carbon, hydrogen and halogen atoms. Chemical structure was encoded using various molecular descriptors. A quantitative structure-property relationship model was established using the multiple linear regression models. The cross-validation ability of the created m...

To establish the method for qualitative and quantitative determination of gallic acid in Herba Gei. Gallic acid content is determined by HPLC with Diamonsil C18 column as the stationary phase, under the conditions of methanol-0.1% phosphoric acid in water (10:90) mobile phase, 271 nm detection wavelength, and 40°C column temperature. Peak area of gallic acid shows a good linearity with the inje...

Here we report on the utilization of Laser-Induced Breakdown Spectroscopy (LIBS) for determination of Quantum Dots (QDs) in liquid solution. The process of optimization of experimental conditions from choosing the carrier medium to application of colloid QDs is described. The main goal was to get the best possible signal to noise ratio. The results obtained from the measurements confirmed the c...

Various algorithms have been proposed for the determination of the optimum path(s) in line networks. Moving in space under constraints is a far more complex problem, where research has been relatively scarce. An example would be the determination of the shortest sea course between two harbors. This paper presents a graph-based approach to the problem of the optimum path(s) finding in space; and...

For at least two decades different mass spectrometric techniques have been applied for polymer analysis, including the qualitative determination of chemical compositions, end group identification, functionality type distribution and the determination of the cyclisation extend at each degree of polymerisation. Molecular weights exceeding 100 KDa are provable by MALDI-ToF mass spectrometry. Furth...

Qualitative determination of C-reactive protein (CRP) was evaluated as a diagnostic method for community-acquired pneumonia. Paired serum and pleural fluid samples from child patients were examined with a CRP test, compared to bacterial cultures, counterimmunoelectrophoresis and immunoassay. The CRP test gave excellent parameters of sensitivity, specificity and predictive values for the diagnos...
