The article relates to the relations between the urban forms and the productivity of the collective services. It is based on the distinction between three types of technical supply : infrastructures, superstructures and the road servicing by specialized agents. The researches developed for the...

This paper deals with the modeling of a biotechnological process used for wastewater treatment. Bond Graph method is an appropriate tool for modeling such a nonlinear process. The so-called pseudo Bond Graph method is proposed as a modeling technique for an aerobic process of biological...

This study builds on earlier work in the oil and gas industry that observed a negative relationship between pollution and profit. We argue that new technology lowers the cost of clean operations, and that a reduction in waste-emission enhances revenue streams and reduces the cost of waste treatment.

Water is today considered to be a vital and limited resource due to industrial development and population growth. Developing appropriate water treatment techniques, to ensure a sustainable management, represents a key point in the worldwide strategies. By removing both organic and inorganic...
