Dark adaptor goggles, also called red adaptation goggles, are goggles are made with red-tinted plastic lenses. They were invented by Wilhelm Trendelenburg in 1916, based on the work by Antoine Béclère on dark adaptation of the eye. The eyewear are often used by observers to preserve their natural night vision .
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions. RO can remove dissolved or suspended chemical species as well as biological substances (principally bacteria), and is used in ...
Single-phase solar desalination. In indirect, or single phase, solar-powered desalination, two systems are combined: a solar energy collection system (e.g. photovoltaic panels) and a desalination system such as reverse osmosis (RO). The main single-phase processes, generally membrane processes, consist of RO and electrodialysis (ED).
Color blindness (color vision deficiency) is the decreased ability to see color or differences in color. It can impair daily color tasks such as selecting ripe fruit or choosing clothing, as well as safety-related tasks such as interpreting traffic lights. While the disability of color blindness is considered minor, the use of color in safety ...
Cranberry glass. The beaker with lid made from Gold Ruby is attributed to Johann Kunckel. Cranberry glass or 'Gold Ruby ' glass is a red glass made by adding gold salts or colloidal gold to molten glass. Tin, in the form of stannous chloride, is sometimes added in tiny amounts as a reducing agent. The glass is used primarily in expensive ...
Osmotic power, salinity gradient power or blue energy is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO). Both processes rely on osmosis with membranes. The key waste product is brackish water.
If you view the image with red-cyan 3D glasses, the text will alternate between Red and Blue. 3D red cyan glasses are recommended to view this image correctly. Anaglyph 3D is the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan .
A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment ...
