The Office of the Comptroller of the Currency (OCC) is an independent bureau within the United States Department of the Treasury that was established by the National Currency Act of 1863 and serves to charter, regulate, and supervise all national banks and federal thrift institutions and the federally licensed branches and agencies of foreign banks in the United States.

Montreal Protocol [5] [6] – The Montreal Protocol was a globally coordinated regulatory action that sought to regulate ozone-depleting chemicals. 191 countries have ratified the treaty. Global Framework on Chemicals - The plan was adopted on 30 September 2023 in Bonn at the fifth session of the International Conference on Chemicals Management ...

The light-harvesting system of PSI uses multiple copies of the same transmembrane proteins used by PSII. The energy of absorbed light (in the form of delocalized, high-energy electrons) is funneled into the reaction center, where it excites special chlorophyll molecules (P700, with maximum light absorption at 700 nm) to a higher energy level.
The former sense is sometimes called luminous efficacy of radiation, [4] and the latter luminous efficacy of a light source [5] or overall luminous efficacy. [ 6 ] [ 7 ] Not all wavelengths of light are equally visible, or equally effective at stimulating human vision, due to the spectral sensitivity of the human eye ; radiation in the infrared ...
Photochemical immersion well reactor (50 mL) with a mercury-vapor lamp.. Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible (400–750 nm), or infrared radiation (750–2500 nm).
Dextrorotation and laevorotation (also spelled levorotation) [1] [2] in chemistry and physics are the optical rotation of plane-polarized light.From the point of view of the observer, dextrorotation refers to clockwise or right-handed rotation, and laevorotation refers to counterclockwise or left-handed rotation.
They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. [citation needed] Each guard cell has a relatively thick and thinner cuticle [clarification needed] on the pore-side and a thin one opposite it. As water enters the cell, the thin side bulges outward like a ...
