Ultra-high vacuum (often spelled ultrahigh in American English, UHV) is the vacuum regime characterised by pressures lower than about 1 × 10 −6 pascals (1.0 × 10 −8 mbar; 7.5 × 10 −9 Torr). UHV conditions are created by pumping the gas out of a UHV chamber.
Ion pumps are commonly used in ultra-high vacuum (UHV) systems, as they can attain ultimate pressures less than 10 −11 mbar. [1] In contrast to other common UHV pumps, such as turbomolecular pumps and diffusion pumps, ion pumps have no moving parts and use no oil. They are therefore clean, need little maintenance, and produce no vibrations.
UHV may refer to: Ultra-high vacuum, the vacuum regime characterised by pressures lower than about 10 −7 pascal; Ultra-high voltage, a classification of overhead power line with an operating voltage of higher than 800 kV; University of Houston–Victoria, a university in Victoria, Texas, US
UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels (initially) 1 to 13, and UHF channels (initially) numbered 14 to 83. Compared with an equivalent VHF television transmitter, to cover the same geographic area with a UHF transmitter requires a higher effective radiated power , implying a more ...
The UHV grid will aid China's plan of electrification and decarbonization, [15] and enable integration of renewable energy by removing the transmission bottleneck that is currently limiting expansions in wind and solar generation capacity whilst further developing the market for long-range electric vehicles in China.
Right Here Right Now is a short film written and directed by Anand Gandhi. It earned critical acclaim and wide audience appreciation in the following years at the Indo-British Film and Video Festival. It has achieved a near-cult status in the Indian parallel cinema.
A music video, directed by Stuart Orme, was made for the song, featuring Tony Banks and Mike Rutherford playing their instruments (piano and electric guitar respectively) on the back of a truck, with a bearded Collins driving a 1950s model Ford convertible making stops at various locations around Los Angeles (the Capitol Records Tower can be seen in the background and street signs for ...
Alternative Influence: Broadcasting the Reactionary Right on YouTube is a 2018 report by researcher Rebecca Lewis published at the think tank Data & Society that performs network analysis on a collection of 65 political influencers on 81 YouTube channels. Lewis argues that this network propagates right-wing ideology.
