Coal is complicated macromolecular compound composed of acomatic structure which is difficult to decompose.
Meanwhile increasement of pressure results in greater density which promotes devolatilization and hydrolysis of macromolecular structure.

However, there has been few studies of flavor chemistry on P. aibuhitensis.
The sensory characters of the both are obviously different, it must be relation to the chemical structures of contained compounds.
Sucrose has more complicated molecular structure than glucose, therefore, MRPs from sucrose is more complicated than that from glucose after maillard reaction under high temperature.

In this context, the RPC, even if it does not contain integral component, can assure steady state error 0kW due to the fact that the integral component is contained in the structure of the control system direct channel (in the HSM structure).

To the authors’ knowledge, none of them consider a possible geopolymers/zeolites secondary transformation, despite the fact that starting materials and process of synthesis are close to those involved in the formation of zeolites and that the presence of zeolitic structures embedded in geopolymer matrix has been reported [12-15].
As sodium-based geopolymer seem to be less disturb by the presence of anionic species than potassium-based geopolymer, the structure making ability of smaller cations in comparison to larger ones [23] should also be taken into account.
Initial mix formulation and curing conditions are of primary importance for the chemistry and nature of final products as well as for the transformation of geopolymers into crystalline materials [24].
