101CIRCUITS ÉLECTRIQUES — Un circuit ou réseau électrique est constitué par un ensemble de dispositifs qui assurent la production, le traitement et la conversion d’une énergie ou d’un signal électrique. Aussi, apparaît il comme un constituant essentiel des montages de… …
102Chlorophyll — Leaf green redirects here. For the video game, see Pokémon FireRed and LeafGreen. Chlorophyll gives leaves their green color and absorbs light that is used in photosynthesis …
103Cross section (physics) — A cross section is the effective area which governs the probability of some scattering or absorption event. Together with particle density and path length, it can be used to predict the total scattering probability via the Beer Lambert law. In… …
104Isotropy — is uniformity in all orientations; it is derived from the Greek iso (equal) and tropos (direction). Precise definitions depend on the subject area. Exceptions, or inequalities, are frequently indicated by the prefix an, hence anisotropy.… …

106Optical density — In optics, density is a unitless measure of the transmittance of an optical element for a given length at a given wavelength λ : [cite book|title=The Focal Digital Imaging A Z|first=Adrian|last=Davies|url=http://books.google.com/books?id=j7l0CxBUw… …
107Window — This article is about the part of a building. For the Microsoft operating system, see Microsoft Windows. For other uses, see Window (disambiguation) and Windows (disambiguation). Pair of windows, Old Ship Church, Hingham, Massachusetts …
108Thermal conductivity — In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier s Law for heat conduction.First, we define heat conduction by the formula::: H=frac{Delta Q}{Delta t}=k …
109Trombe wall — A Trombe wall is a sun facing wall built from material that can act as a thermal mass (such as stone, metal, concrete, adobe or water tanks), combined with an air space, insulated glazing and vents to form a large solar thermal collector. Edward… …
110Ultraviolet-visible spectroscopy — or ultraviolet visible spectrophotometry (UV/ VIS) involves the spectroscopy of photons in the UV visible region. It uses light in the visible and adjacent near ultraviolet (UV) and near infrared (NIR) ranges. In this region of the… …
