CNIPsy 2010 Marseille : 7ème Congrès National des Internes en Psychiatrie (CNIPsy). Thème : «Mauvais genre»
Session : Sexualité et psychiatrie : un mélange des genres.
Titre : CNIPsy 2010 Marseille - De la psychiatrie à la sexologie : un parcours atypique.
Résumé : Le sexe est un sujet dont tout le monde parle. Comment aborder ce sujet en tant que psychiatre face à un patient est un problème autrement plus complexe. Pour un prescripteur, le sujet pourra être a

3 Summary
Hydroelectric energy is ultimately solar energy converted through evaporation of water, movement of air masses and precipitation to gravitational potential energy and then to the kinetic energy of water flowing down a slope. That energy was harnessed for centuries through the use of water wheels to drive mills, forges and textile works, before being supplanted by coal-fired steam energy. The unit considers hydropower as a potential source of useable energy.

The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows. This unit considers the power

Wind energy was the fastest growing power source at the starts of the 21st century, yet wind-driven mills and pumps, and nautical sails for transport, were, along with waterwheels, the first mechanical devices to power industrial production. The advantages of harnessing wind energy are obvious; it is free, clean and widely available. This unit explores the Wind as a potential source of useable energy.
