Abstract

La connaissance approfondie du gisement lumineux extérieur est un élément essential pour l'évaluation des performances lumineuses de bâtiments, ainsi que le développement de nouveaux systèmes d'éclairage naturel. La mesure de la distribution de luminances sur la voûte céleste se pratique grâce à un photo-uranotomographe. De tels scanners de ciel sont commercialisés et souffrent des défauts suivants: - Durée de la mesure importante: 30s à plusieurs minutes - Manque de souplesse de la mesure: ils ne permettent de balayer l'hémisphère que selon une seule répartition (145 zones de Tregenza/CIE) - Faible dynamique de mesure: la zone circumsolaire est exclue de la mesure Un nouveau type de photo-uranotomographe basé sur la technique d'imagerie numérique a été développé afin de contourner les défauts des dispositifs existants. L'objet de cette contribution est de présenter le développement d'un photo-uranotomographe à imagerie numérique et d'un illustrer sa mise en service.

Heavy metals

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical behaviour. More specific definitions have been published, none of which have been widely accepted.

Mercury (element)

Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum (haɪˈdrɑrdʒərəm ) from the Greek words hydro (water) and argyros (silver). A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.

Period 2 element

A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties. The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
