Sébastien Forget,Sébastien Chénaisties vary; under appropriate conditions (e.g., abundance of Fe- and P-containing nutrients) microalgal blooms may form.. Dense microalgal populations maybe detrimental to water quality, although they may also be exploited for human benefit. For example, in shallow oxidation ponds or waste stabilizat

Sébastien Forget,Sébastien Chénaisin the Desert with an increasing use of sewage around the Great Cairo. Gabal el Asfar sewage farm is an example, in which more than 80 years treated sewage effluent is applied. This farm covers more than 1,250 ha and located approximately 25 km NE of Cairo, at the fringes of Delta floodplain. To eva

Normal primary and secondary treatment of these wastewaters eliminates the easily settled materials and oxidizes the organic material present, but does not remove the nutrients which will cause eutrophication of the rivers or lakes into which these wastewaters may be discharged

Organic Materials for Solid-State Lasers, chemical structure and the optical properties of some of the main families widely used as gain materials or host matrices in organic lasers. The technological processes allowing organic molecule deposition in various forms are then reviewed, as well as the main experimental techniques used to measure crucial parameters such as optical gain.
