Madrid, November 11, 2010 - The control and utilization of waste and increasing need for renewable energy is a priority in today's society. These topics are very aware of chemical engineering, which through its advances help make these goals a reality in the corporate sector and within society.

For this reason, important personalities from the world of chemical engineering will meet in Madrid to discuss various topics of social importance in the XIII National Congress of Chemical Engineering (CNIQ). Will take place on 18, 19 and 20 November in the School of Industrial Engineers. Professionals such as Professor D. Richard Darton, President of the European Federation of Chemical Engineering or Ms. Maida Arieta-Araunabeña entitled in Chemical Engineering from the University of the Basque Country manifest progress in these fields.

The Higher Council for Scientific Research (CSIC) and Gregorio Maranon hospital in Madrid, and Clínic, Barcelona, collaborate in the development of the first phase I clinical trial being held in Spain for a preventive vaccine against HIV, the virus responsible for AIDS pandemic. Since its discovery in 1981, this disease has killed more than 25 million people. There are currently some 40 million infected worldwide, and AIDS has a mortality rate of about 3 million people a year.

The general problems of particle motion in the vicinity of a flat, non-deforming fluid interface is studied. The approximate singularity method used by previous workers in this research group has been generalized to consider the motion of a sphere in any linear velocity field compatible with the existence of the undisturbed flat interface, and the motion of slender rod-like particles which undergo an arbitrary translation or rotation in either a quiescent fluid or in a linear flow. The theory yields the hydrodynamic mobility tensors which are necessary to describe Brownian movement near a phase boundary, as well as general trajectory equations for sedimenting particles near a fluid interface with an arbitrary viscosity ratio. These approximate solution results are in good agreement with both exact-solutions where they are available and experimental data for motion of a sphere near a rigid plane wall. Among the most interesting results for motion of slender bodies is the generalization of Jeffery orbit equations for linear simple shear flow.
