Vacuum state

This specification covers vacuum-treated carbon and alloy steel forgings for turbine rotors and shafts. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This specification covers vacuum-treated alloy steel forgings intended for use as turbine rotor disks and wheels. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

"Standard Specification for Ferrochromium" covers two types of ferrochromium designated as high carbon and low carbon, the latter including nitrogen-bearing and vacuum grades. The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

"Standard Specification for Pressure Vessel Plates, Alloy Steel, Nickel" covers nickel-alloy steel plates intended primarily for welded pressure vessels. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents. Therefore, each system must be used independently of the other.

This specification covers vacuum-treated 12 % chromium steel forgings for turbine rotors and shafts. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

In this paper, we study some non-classical properties and propose the generation schemes of the superposition of multiple-photon-added two-mode squeezed vacuum state (SMPA-TMSVS). Based on the Wigner function, we clarify that this state is a non-Gaussian state, while the original twomode squeezed vacuum state (TMSVS) is a Gaussian state.

The Higgs production was studied using the Randall-Sundrum model from photonphoton collision. The independent parameters in the Randall-Sundrum model: The vacuum expectation value of the radionfield A0, the radion mass M0, the Higgs mass Mh and E must be specified to fix the state mixing parameters.

In this paper, we investigate the phenomena of concentration and cavitation and the formation of delta-shocks and vacuum states in solutions of the pressureless type system with flux approximation. First, the Riemann problem of the pressureless type system with a flux perturbation is considered.

A two-gram sample was oven-dried and placed into a 250 mL Erlenmeyer flask with 100 mL of distilled water. A reflux condenser was attached to the flask and the apparatus was placed in a gently boiling water bath for three hours. Special attention was given to insure that the level of the solution in the flask remained below that of the boiling water. Samples were then removed from the water bath and filtered by vacuum suction into a fritted glass crucible of known weight. The residue was washed with hot tap water before the crucibles...

A valve amplifier or tube amplifier is a type of electronic amplifier that makes use of vacuum tubes to increase the amplitude of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s. Valve amplifiers are used for applications such as guitar amplifiers, satellite transponders such as DirecTV and GPS, audiophile stereo amplifiers, military applications (such as radar) and very high power radio and UHF television transmitters....
