Estimation of the Heat of Reaction in Traditional Ceramic Compositions

Compositions of Functions and Permutations Specified by Minimal Reaction Systems

This paper studies mathematical properties of reaction systems that was introduced by Enrenfeucht and Rozenberg as computational models inspired by biochemical reaction in the living cells. In particular, we continue the study on the generative power of functions specified by minimal reaction systems under composition initiated by Salomaa. Allowing degenerate reaction systems, functions specifi...

Benzene nitration: validation of heterogeneous reaction models

The film and the Danckwerts penetration models were used to model the heterogeneous liquid–liquid reaction of benzene nitration. Analytical solutions were developed for both models considering a pseudo-first order reaction. Models were confronted with experimental results showing good predictions in the intermediate reaction regime (0.3<Ha< 2). Profiles of both models were evaluated confirming ...

Compositions versus Cyclic Compositions

We prove that the sum of greatest common divisors of parts in all compositions of n equals the sum of lengths of all cyclic compositions of n. The proof highlights structural similarities between the set of compositions of n and the set of cyclic compositions of n. 1. Definitions and Statement A composition of the positive integer n is an ordered partition of n; that is, a vector ( ) r p p ...,...

Reactive uptake coefficients for heterogeneous reaction

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The kinetics of uptake of gaseous N 2 O 5 on submicron aerosols containing NaCl and natural sea salt has been investigated in a flow reactor as a function of relative humidity (RH) in the range 30–80% at 295±2 K and a total pressure of 1 bar. The measured...
