The objective of this work was to evaluate the removal of ibuprofen (IBP) using the oxidants hydrogen peroxide (H(2)O(2)) and sodium persulfate (Na(2)S(2)O(8)). The ability of magnetite (Fe(3)O(4)) to activate persulfate (PS) and H(2)O(2) for the oxidation of IBP at near neutral pH was evaluated as well. The use of soluble Fe(2+) to activate H(2)O(2) and(More)
The aim of this work was to apply an experimental design to formulate a stable depilatory cream at ambient temperature. A preliminary study was performed to optimize the most accurate operating parameters, which are then used for the determination of the rheological properties. Long-term stability of the emulsion formulations was investigated to obtain the(More)
Despite the rapid evolution of computers in mobile environments, current middleware are inadequate in mobile environments where resources can vary a lot and even disappear. Most of research works dealing with disconnection management do not provide a design model for applications. In this article, we present MADA, an approach to design distributed(More)
The concept of multi-synchronous interaction has become popular in the context of collaborative work [7]. This cooperation mode allows the participants of a virtual team to alternate periods of work in coupled mode collaborating with the other team members with isolated work in uncoupled mode. As divergence may then occur, a reconciliation mechanism is(More)
