“…A useful mathematical model to describe the degradation of works of art due to the action of external agents has been introduced by Brazzoli et al [31]. This model, based on the Kinetic Theory Approach [32], assumes that the state of a given system can be identified by a number of independent variables, each one linked to a proper probability distribution.…”

Heating, Ventilating and Air-Conditioning systems in museums are called to properly control important microclimate parameters, not only for visitors' wellbeing, but mostly for the preservation of works of art. Accordingly, in case of interruptions to Heating, Ventilating and Air-Conditioning systems, due to maintenance interventions or drawbacks, it is essential to guarantee the acceptable break from service to which possible damages for the works of art are related. In this regard, the aim of this work is to introduce a simple indicator to support curators in regulating the stipulation of contracts with external companies, a more effective management and maintenance of the Heating, Ventilating and Air-Conditioning systems will thus be achieved in order to preserve the works of art, by integrating into the contracts economic penalties related to the system's service break period. The feasibility of this new procedure has been checked by means of a case study involving the "Museo Regionale" of Palermo (Italy).

“…As already mentioned, the analysis has been motivated by paper [7], which was however limited to the case of conservative interactions, while this work deals with the more general case of proliferating/destructive events which occur in various fields of applied sciences, e.g. in biology [4].…”

“…On the other hand, a suitable development of the methods of the kinetic theory for active particles applied to open systems subject to external actions is proposed in [7], which deals with the modelling of degradation phenomena for works of art under the action applied by external agents. The model consists in an evolution equation for the probability distribution of the degradation stage.…”

This work deals with a methodological development of the kinetic theory for open systems of active particles with discrete states. It essentially refers to the derivation of mathematical tools which provide the guidelines for modelling open systems in different fields of applied sciences. After a description of closed systems, mathematical frameworks suitable for depicting the evolution of open systems are proposed. Finally, some research perspectives towards modelling are outlined.

“…Kinetic data of ingredients content changes is useful for maximizing material quality and minimizing the losses during thermal treatment (Balsa-Canto, Rodriguez-Fernandez and Banga, 2007;Brazzoli et al, 2007), in addition, kinetic parameters namely, reaction order, rate constant and activation energy provide useful information regarding the characteristic changes during heating (Takeo et al, 2000). Thus, getting the kinetic information on these three compounds during thermal processing and applying these information on actual process would be beneficial to predict Jiangpo quality.…”

Jiangpo is an increasingly popular East Asian spice which is made from Mangnolia officinalis bark and ginger juice. Since it induces bioactive compounds decomposition and has influence on final flavor and fragrance, cooking is regarded as the key operation in preparation of Jiangpo. To evaluate the bioactive compounds content changes of Jiangpo during thermal processing, kinetic parameters including reaction order, rate constant, T1/2 and activation energy of bioactive markers namely honokiol, magnolol and curcumin were determined. Cooking was set at temperatures 60, 90 and 120°C for selected time intervals. Results displayed the thermal kinetic characteristics of the three compounds. Thermal degradation of Honokiol and magnolol both followed first order kinetic model and the loss of curcumin fitted second order. A mathematical model based on the obtained kinetic parameters has also been developed to predict the degradation of honokiol, magnolol and curcumin in non-isothermal state. All the information in this paper could contribute necessary information for optimizing the existing heat processing of Jiangpo.
