The conversion of sunflower oil cake (SOC) into methane by mesophilic anaerobic digestion was the object of this study. The effect of a combined dilute acid-thermal pretreatment (acid concentration and temperature) on solubilisation and methane potential was investigated using a central...

Using the Fuoss-Onsager theory we recently obtained simple expressions for the variation with concentration of the transport coefficients of electrolytes in aqueous solution. We studied self-diffusion, conductance of binary and ternary ionic mixtures, and micellar systems. We used in the...

Combining algae and bacteria in High Rate Algal/Bacterial Ponds (HRABP) is an emerging technology for wastewater treatment benefiting from two theoretical advantages: algae produce oxygen for the bacteria therefore reducing the energy need for oxygen supply, while nitrogen and phosphorus can be...

The aim of this paper is to explain why Statistical Physics can help understanding two related linguistic questions. The first question is how to model first language acquisition by a child. The second question is how language change proceeds in time.

De plus en plus de villes moyennes investissent dans des transports collectifs en site propre, c'est le cas de l'agglomération de Dijon qui mettra en service ces deux premières lignes de tramway à l'horizon 2013. Rapportée à la taille de l'agglomération, l'étendue du tracé est très...

Evolutionary Algorithms (EA) have proven to be very effective in optimizing intractable problems in many areas. However, real problems including specific constraints are often overlooked by the proposed generic models. The authors' goal here is to show how knowledge engineering techniques can be...
