Mercury rectifier on display in the Beromünster AM transmitter in Switzerland, before being decommissioned.Three-phase full-wave rectifier with six anodes. A mercury-arc valve or mercury-vapor rectifier or (UK) mercury-arc rectifier [1] [2] is a type of electrical rectifier used for converting high-voltage or high-current alternating current (AC) into direct current (DC).
Caldera, Inc. was a Canopy-funded software company founded in October 1994 [1] and incorporated on 25 January 1995 [2] by former Novell employees Bryan Wayne Sparks, Ransom H. Love and others to develop the Caldera Network Desktop (CND) and later create a Linux distribution named OpenLinux (COL).
The work done in a process on vapor cycles is represented by length of h, so it can be measured directly, whereas in a T–s diagram it has to be computed using thermodynamic relationship between thermodynamic properties. [1] In an isobaric process, the pressure remains constant, so the heat interaction is the change in enthalpy. [2]
Valles Caldera is the younger of two calderas known at this location, having collapsed over and buried the older Toledo Caldera, which in turn may have collapsed over yet older calderas. The associated Cerros del Rio volcanic field , which forms the eastern Pajarito Plateau and the Caja del Rio , is older than the Toledo Caldera.
The term caldera was introduced into the geological vocabulary by the German geologist Leopold von Buch when he published his memoirs of his 1815 visit to the Canary Islands, [note 1] where he first saw the Las Cañadas caldera on Tenerife, with Mount Teide dominating the landscape, and then the Caldera de Taburiente on La Palma.

Other variations of turbines have been developed that work effectively with steam. The de Laval turbine (invented by Gustaf de Laval) accelerated the steam to full speed before running it against a turbine blade. De Laval's impulse turbine is simpler and less expensive and does not need to be pressure-proof. It can operate with any pressure of ...
The caldera is one of the largest of the few calderas in western Canada, measuring about 30 kilometres (19 mi) long (north-south) and 20 kilometres (12 mi) wide (east-west). [1] Mount Silverthrone, an eroded lava dome on the caldera's northern flank, which is 2,864 metres (9,396 ft) high, may be the highest volcano in Canada. [1]
The topography encompasses the outline of an older caldera so suggesting there were pyroclastic flows that pre-dated the formation of present-day Aira Caldera. The first phase of activity resulted from injection of mafic magmas that destabilized the stored rhyolite magma [ 11 ] and was the mainly homogeneous Osumi Pumice Fall (named because the ...
