As all classic methods for kinetic analysis of data from thermal analysis experiments, the nonparametric kinetics method, NPK, assumes that the general expression for the reaction rate of a simple reaction is $$ {\dot{\alpha } = g(\alpha ) \cdot f(T)} $$ (16.1) where g(α) symbolizes the kinetic model of the process and f(T) accounts for the ...

General Methods of Kinetic Model Reduction
IFAC Proceedings Volumes, 1995Abstract Two novel approaches to simplification of a kinetic mechanism are presented. The first combines macroscopic reactor balances with linear variable selection techniques from the statistics literature. The second approach formulates the network reduction problem as a combinatorial optimization problem that is solved using genetic algorithms ...

An automated method for acetylcholinesterase kinetics
Analytical Biochemistry, 1976Abstract An automated assay for acetylcholinesterase (EC 3.1.1.7.) has been developed based on the manual spectrophotometric method of Ellman et al. (1). This method was used to determine (a) the enzyme activity of an unknown sample and (b) the dependence of initial rates given by a fixed enzyme concentration on the substrate concentration.

Kinetic force method and two-particle kinetic equation
AIP Conference Proceedings, 2014In the report, the algorithm of the Kinetic Force Method founded on a kinetic equation for auxiliary two-particle distribution function of quasiparticle pairs is considered. It is known that in the interaction of quasiparticle pairs, energy and momentum are conserved for each individual pair.

Convenient method for studying enzyme kinetics
Biotechnology and Bioengineering, 1979AbstractA convenient method for enzyme kinetic studies is introduced. The method includes identification of reaction mechanism and estimation of the associated kinetic constants with a minimum number of experiments. The application of the method is illustrated by using literature data. Factors limiting the application of this method are also discussed.

Problems in which turbulent flow fields dominate form a major portion of engineering fluid mechanics and heat transfer work. In principle, the calculation of these flows involves the solution of the time-dependent Navier-Stokes equations. But these equations cannot be solved without recourse to numerical methods, which must divide the flow field into a

Schematic methods for probabilistic enzyme kinetics
Journal of Theoretical Biology, 1992The theory of steady-state enzyme processes which avoids using the mass action law of chemical kinetics and consistently describes catalytic mechanisms by probabilistic concepts has recently been proposed (Mazur, 1991, J. theor. Biol. 148, 229-242). To facilitate the analysis of complex reaction graphs by this theory the possibility of constructing ...

The PN model discussed in the preceding chapter is a continuum approach that requires some atomistic input to account for non-linear interactions in the dislocation core. In this chapter, we introduce yet another continuum model that uses atomistic input for a different purpose.

Optimization Method for Simultaneous Kinetic Analysis
Analytical Chemistry, 1996Kinetic analysis is often carried out for simultaneous determinations; thus, a theory to establish its optimal conditions is necessary. A very simple and fast model to find conditions for optimum analytical performance and to predict the quality of simultaneous kinetic analysis has been developed.

Entropy considerations in kinetic method experiments
Journal of Mass Spectrometry, 2004AbstractIn extended kinetic method experiments, relative binding enthalpies (‘affinities’) and relative entropies are obtained based on unimolecular dissociation kinetics. A series of ion‐bound dimers AXBi is formed, in which the sample (A) and structurally similar reference molecules (Bi) are bridged by a central cation or anion (X).
