of the earth. Therefore, great efforts are being made to mitigate the N 2 O concentrations from the vented industrial emissions developing practical approaches [ 1 , 3 , 4 ].
The catalytic decomposition of N 2 O represents the most direct
Maximal clique enumeration and maximum clique generation are well known NP-complete discrete optimization problems. Researchers experiment with parallel implementations of known algorithms in order to speed up the resolution process. Parallel implementations are equivalent to divisions of the feasible region that is an implicit decomposition of the original problem. The below study looks for the possible ways of explicit decomposition, which can subsequently serve as bases of parallel algorithms. The paper introduces formally the notion of decomposition, specifies explicit algorithms for different sorts of decomposition, provides and compares decomposition based algorithms for the maximum clique problem.

The kinetics of thermal decomposition of several compounds of the general type have been previously studied using experimental techniques 1 – 4 ]. It has been shown that elimination of molecular hydrogen occurs
In recent years there has been increasing research interest in the removal of nitrogen-oxides from exhaust gases using a pulsed corona discharge reactor. The pulsed streamer corona produces energetic electrons that excite, ionize and dissociate gas molecules, and by forming radicals that enhance the gas-phase chemical reactions which reduce the pollutant’s concentration.In this paper a method is presented, where the reaction rates of the electron-molecule collision are determined. The model is based on calculation of the energy of free electrons in the time and space varying field, considering the mean free path and the energy-dependent reaction cross sections of molecules. Knowing the rates, it is possible to solve the reaction kinetic equations, and to get the time-evolution of by-products, and the decomposition ratio of the pollutant gases.
