For the further discussion, we shall thus assume an electron optical resolution of 80 Af and phosphor screen resolution of 60 Af.

For this, a phosphor coating is applied to a surface of interest and, usually, the decay time is the emission parameter that indicates temperature.

For white LEDs, a blue LED is used with a yellow phosphor, or with a green and yellow SiAlON phosphor and a red CaAlSiN < sub > 3 </ sub >- based ( CASN ) phosphor.

For most devices, the screen's phosphors quickly lose their excitation between sweeps of the electron gun, and the afterglow is unable to fill such gaps – see phosphor persistence.

For example, if a Cathode Ray Tube computer monitor's vertical refresh rate is set to 60 Hz, most monitors will produce a visible " flickering " effect, unless they use phosphor with long afterglow.

For example, although their designs are identical in every way apart from the metal used, the Yanagisawa A992 and T992 ( phosphor bronze ) alto and tenor saxophones sound noticeably " darker " than the A991 and T991 ( brass ) versions.

For the same reason, the output fiber plate is planoconcave, its exposed flat side permitting contact photography if a permanent record is desired.

For instance, nanotubes form only a tiny portion of the material ( s ) in ( primarily carbon fiber ) baseball bats, golf clubs, or car parts.

For example, the fibers in carbon fiber materials and rebars in reinforced concrete are oriented to withstand tension.

For this migration, ISDN services will be retired, and fiber optic services are recommended as an alternative.

For example, both PNGinc and International Turbine And Power, LLC use carbon fiber discs in their Tesla turbine designs.

For these purposes, manufactured rubber fiber is made as either an extruded round fiber or rectangular fibers that are cut into strips from extruded film.

For a single-mode optical fiber, the cutoff wavelength is the wavelength at which the normalized frequency is approximately equal to 2. 405.

For an optical fiber, the effective mode volume is the square of the product of the diameter of the near-field pattern and the sine of the radiation angle of the far-field pattern.

: Note: For optical fiber dispersion measurement purposes, the quantity of interest is group delay per unit length, which is the reciprocal of the group velocity of a particular mode.

For step index fiber, light entering the fiber will be guided if it falls within the acceptance cone of the fiber, that is if it makes an angle with the fiber axis that is less than the acceptance angle,

For a Gaussian intensity ( i. e. power density, W / m < sup > 2 </ sup >) distribution in a single-mode optical fiber, the mode field diameter is that at which the electric and magnetic field strengths are reduced to 1 / e of their maximum values, i. e., the diameter at which power density is reduced to 1 / e < sup > 2 </ sup > of the maximum power density, because the power density is proportional to the square of the field strength.

For step-index multimode fiber, the acceptance angle is determined only by the indices of refraction of the core and the cladding:

For an optical fiber, the optical axis is along the center of the fiber core, and is also known as the fiber axis.

For example, sending ones and zeros across a wire, fiber, etc.

For an optical fiber or waveguide, a radiation mode or unbound mode is a mode which is not confined by the fiber core.

For plastic-clad silica ( PCS ) fibers, which have a strippable polymer cladding ( not to be confused with the polymer overcoat of an all-silica fiber ), the reference surface may be the core.

For example, bright sunlight is rapidly destructive for living microorganisms suspended in air.

For protein identification, fractions from the column were concentrated by pervaporation against a stream of air at 5-degrees-C or by negative pressure dialysis in an apparatus which permitted simultaneous concentration of the protein and dialysis against isotonic saline.

For all involved in this discussion the devil is a real entity who can really be confronted in the woods on a dark night, the demon world is populated with real creatures, and witches actually can be seen flying through the air.

For Lamprias had said that the first articulate sound made is " alpha ", because it is very plain and simple — the air coming off the mouth does not require any motion of the tongue — and therefore this is the first sound that children make.

For example, in sound recording, fluctuations in air pressure ( that is to say, sound ) strike the diaphragm of a microphone which induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone, or the voltage produced by a condensor microphone.

For a monatomic ideal gas,, and for a diatomic gas ( such as nitrogen and oxygen, the main components of air ).

For instance, internal aerodynamics encompasses the study of the airflow through a jet engine or through an air conditioning pipe.

For foreign news, first a " generic minute " is recorded, then reports are to World Service radio, then the reporter talks to any other programmes that are on air.

In Canto XI of the same book a hermit named Māṇḍakarṇi is mentioned: " For he, great votarist, intent -- On strictest rule his stern life spent -- ... -- Ten thousand years on air he fed ..." ( English quotations are from Ralph T. H. Griffith's translation ).

For example, excess combustion air of 15 percent means that 15 percent more than the required stoichiometric air is being used.

For example, atmospheric air is primarily a mixture of nitrogen, oxygen, and argon, and native solid elements occur in alloys, such as that of iron and nickel.

For example, a shot of a zombie getting its head cut off may, for instance, start with a view of an axe being swung through the air, followed by a close-up of the actor swinging it, then followed by a cut back to the now severed head.

For eleven weeks, between August and October 1979, industrial action forced Coronation Street and the whole of the ITV network ( apart from the Channel Islands ) off the air.

For example, consider air as it is heated or cooled.

For example, air pollution may generate a negative externality, and education may generate a positive externality ( less crime, etc .).

For example, the words heir and air are pronounced identically in most dialects ( as ).

For a pass to be ruled in bounds, the receiver's feet must be in contact with the in bounds portion of the playing field, or, if the ball is caught in the air, either one or two feet must touch the ground within the field boundaries, after the ball is caught.

For instance frost may be observed around cracks in cold wooden sidewalks when moist air escapes from the ground below.

For example, air hoar is a deposit of hoar frost on objects above the surface, such as tree branches, plant stems, wires ; surface hoar is formed by fernlike ice crystals directly deposited on snow, ice or already frozen surfaces ; crevasse hoar consists of crystals that form in glacial crevasses where water vapour can accumulate under calm weather conditions ; depth hoar refers to cup shaped, faceted crystals formed within dry snow, beneath the surface.

For alpha particles and low energy beta particles the " end window " type of GM tube is used as these particles have a limited range even in free air and are easily stopped by a solid material.

For efficient detection of alpha particles the GM tube window should ideally be within 10mm of the radiation source due to the attenuation in free air.

For similar reasons, and also due to the small size of helium atoms, helium's diffusion rate through solids is three times that of air and around 65 % that of hydrogen.

For example, recent studies have suggested genetic variants in deer mice that help explain how deer mice that live in the mountains are able to survive in the thin air that accompanies high altitudes.
