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.
This mast has two UHF antennas for receiving signals from different directions. The lower antenna is a bowtie array. The upper antenna is a Yagi design.. UHF television broadcasting is the use of ultra high frequency (UHF) radio for over-the-air transmission of television signals.
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.
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
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.
Very high frequency (VHF) is the ITU designation [1] [2] [3] for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
