Tidestromia Suffruticosa
''Tidestromia suffruticosa'', the shrubby honeysweet, is a perennial plant in the family Amaranthaceae of the southwestern United States and northeastern Mexican deserts. It has one of the highest rates of photosynthesis ever recorded. It flowers from April to December. It can survive very high temperatures, growing successfully in extreme environments such as Death Valley, and the genetic basis for this is being studied with a view to making hardier crop plants to better cope with climate change In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to E .... Subtaxa The following varieties are accepted: *''Tidestromia suffruticosa'' var.

Torr
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly of a standard atmosphere (). Thus one torr is exactly (≈ ). Historically, one torr was intended to be the same as one "millimeter of mercury", but subsequent redefinitions of the two units made them slightly different (by less than ). The torr is not part of the International System of Units (SI). It is often combined with the metric prefix milli to name one millitorr (mTorr) or 0.001 Torr. The unit was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644. Nomenclature and common errors The unit name ''torr'' is written in lower case, while its symbol ("Torr") is always written with upper-case initial; including in combinations with prefixes and other unit symbols, as in "mTorr" (millitorr) or "Torr⋅L/s" (torr-litres per second). The symbol (uppercase) should be used with prefix symbols (thus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
