Photosynthesis is the chemical process where plants and some bacteria can capture and organically fix the energy of the sun.... The main product of photosynthesis is a carbohydrate, such as the sugar glucose, and oxygen which is released to the atmosphere. All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight. This chemical reaction is catalyzed by chlorophyll acting in concert with other pigment, lipid, sugars, protein, and nucleic acid molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose, or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids.  3, record 7, English, - photosynthesis

The MLS detects naturally occurring microwave thermal emissions from Earth's limb to create vertical profiles of atmospheric gasses, temperature, pressure and cloud ice. MLS looks 90° from the angle of UARS’ [Upper Atmosphere Research Statellite] orbit. Thermal radiation enters the instrument through a three-mirror antenna system. The antenna mechanically scans in the vertical plane through the atmospheric limb every 65. 5 seconds. The scan covers a height range from the surface up to 90 km(55 miles). Upon entering the instrument, the signal from the antenna is separated into three signals for processing by different radiometers. The 63-GHz radiometer measures temperature and pressure.

In the cold blow and flushing style of discharge, the pressure is almost fully relieved from the digester and the relief gases are routes to accumulators for fortifying cooking acid.
