Sentence examples for determination of reactivity from inspiring English sources
The copolymer composition obtained from the 1H NMR spectra led to the determination of reactivity ratios.
The work was focused on determination of reactivity worth and on evaluation of the calculation to experiment agreement of various nuclear data libraries in case of integral critical experiments in various core configurations.
UNIFAC group contribution method for determination of local monomer concentrations and the simplex method for determination of reactivity ratios were used to describe the terminal and penultimate models of copolymerization in the styrene-acrylonitrile monomer system in bulk at 333.15 K. Results show that the procedure is applicable for prediction of the kinetic behaviour of the comonomer pair.
However, it should be noted that the reactivity ratios of EtOx and SoyOx are both higher than one (k1=1.4; k2=1.7) (full details about the determination of reactivity ratios will be published elsewhere).
It is demonstrated that the isothermal and the isobaric determination of reactivity states yield equivalent results in the pressure regime considered in the present study on Pt and Pd foil.
By the same logic, a more conservative determination of reactivity threshold could be derived from the RDL (0.09 µg/mL) corresponding to a concentration of 4.5 µg/mL in an undiluted serum sample.
Chemical characterization includes a determination of the reactivity of the metal with other substances and the chemical stability of the compounds formed.
Studies of thermal gravimetry/differential thermal analysis (TG/DTA) have allowed the determination of the reactivity grade of different duplex coatings obtained by controlling the densification level of the outer layer, using different heat treatments for the coated particles.
This equipment can also be used as a fast screening tool for the determination of other reactivity parameters, such as flame speeds and rates of pressure rise, through which the most reactive mixture can be identified for more detailed measurements in the larger ISO 1 m3 vessel.
The flame diagnostics consist of one-dimensional (1-D) Planar Laser-Induced Fluorescence (PLIF) for measurements of NO and CH concentrations, 1-D NO-LIF thermometry, and 1-D Particle Tracking Velocimetry (PTV) for the determination of flame reactivity and burning rates.
