Electron lenses are designed to act in a manner emulating that of an optical lens, by focusing parallel rays at some constant focal length.

Electron states are best represented by time-depending " mixtures " ( linear combinations ) of multiple orbitals.

There are at least 500 known games for the Electron and the true total is probably in the thousands.

FireTrack exploits a division in the way the Electron handles its display — of the seven available graphics modes, two are configured so that the final two of every ten scanlines are blank and are not based on the contents of RAM.

Notable enterprises which produced discs of such software are BBC PD, Electron User Group and HeadFirst PD.

Electron avalanches are essential to the dielectric breakdown process within gases.

There are a number of common, standard and manufacturer-driven numbering and coding schemes for diodes ; the two most common being the EIA / JEDEC standard and the European Pro Electron standard:

Electron beams are used in welding, which allows energy densities up to across a narrow focus diameter of and usually does not require a filler material.

Electron microscopes are used to observe a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, metals, and crystals.

Electron microscopes are expensive to build and maintain, but the capital and running costs of confocal light microscope systems now overlaps with those of basic electron microscopes.

For discrete devices, for example, there are three standards: JEDEC JESD370B in United States, Pro Electron in Europe and Japanese Industrial Standards ( JIS ) in Japan.

Electron beam tomography is a specific form of CT in which a large enough X-ray tube is constructed so that only the path of the electrons, traveling between the cathode and anode of the X-ray tube, are spun using deflection coils.

Electron transport chains are the cellular mechanisms used for extracting energy from sunlight in photosynthesis and also from redox reactions, such as the oxidation of sugars ( respiration ).

Electron transport chains are major sites of premature electron leakage to oxygen, generating superoxide and potentially resulting in increased oxidative stress.

Solvent-based Inks, Water-based Inks, EB ( Electron Beam ) curing inks, UV ( ultraviolet ) Curing Inks and two-part chemically-curing inks ( usually based on polyurethane isocyanate reactions ), although these are uncommon at the moment.

Electron capture for almost all non-noble gas atoms involves the release of energy and thus are exothermic.

Electron densities are often be rendered in terms of an isosurface ( an isodensity surface ) with the size and shape of the surface determined by the value of the density chosen, or in terms of a percentage of total electrons enclosed.

Electron densities are often probed with X-ray diffraction scans, where X-rays of a suitable wavelength are targeted towards a sample and measurements are made over time to represent, probabilistically, where electrons can be found, from these positions molecular structures can often be determined for crystallized systems.

Electron beams are useful for treating superficial lesions because the maximum of dose deposition occurs near the surface.

If Acorn had thought to include this small modification in the original Electron design it is likely the machine would have had a much greater impact as it would have nearly doubled the amount of motion possible in games and saved modes 0 – 3 ( including the only 16 colour mode ) from being nearly useless due to contended memory timings.

Of the capabilities present in the BBC Micro but absent from the Electron, the teletext-style mode 7 was particularly conspicuous because of the very low memory usage in that mode ( just less than 1 kB ) and the high number of BBC programs that used it.

The Electron is widely misquoted as operating at 1. 79 MHz after measurements derived from speed testing against the thoroughly 2 MHz BBC Micro for various pieces of ' common software '

On the Electron version of Frak !, the tune was the main theme from " Benny Hill ".

There were also many popular games officially converted to the Electron from arcade machines ( including Crystal Castles, Tempest, Commando, Paperboy and Yie Ar Kung-Fu ) or other home computer systems ( including Impossible Mission, Jet Set Willy, The Way of the Exploding Fist, Tetris, The Last Ninja, Barbarian and SimCity ).

Electron degeneracy pressure is a quantum-mechanical effect arising from the Pauli exclusion principle.

Electron facilities rely on substantial concrete shields to protect workers and the environment from radiation exposure.

The first detection of tau neutrino interactions was announced in summer of 2000 by the DONUT collaboration at Fermilab, making it the latest particle of the Standard Model to have been directly observed ; its existence had already been inferred by both theoretical consistency and experimental data from the Large Electron – Positron Collider.

Electron transitions from these levels in nitrogen and oxygen ions ( or OIII, and ) give rise to the 500. 7 nm line and other lines.

Electron binding energy ( BE ), more accurately, is the energy required to release an electron from its atomic or molecular orbital when adsorbed to a surface rather than a free atom.

* E < sub > ea </ sub > or Electron affinity, the energy required to detach an electron from a singly charged negative ion

Electron binding energy is a measure of the energy required to free electrons from their atomic orbits.

Electrophysiology ( from Greek, ēlektron, " amber " the Electron # Etymology | etymology of " electron ";, physis, " nature, origin "; and ,-logia ) is the study of the electrical properties of biological cells and tissues.

The Acorn Atom was a home computer made by Acorn Computers Ltd from 1980 to 1982 when it was replaced by the BBC Micro ( originally Proton ) and later the Acorn Electron.

The european Pro Electron semiconductor numbering system originated in a similar way from the older Mullard – Philips tube designation.
