electronic mail (e-mail)

a form of COMMUNICATION which involves sending COMPUTER-originated messages and information across a telecommunications network. E-mail usage is expanding rapidly, partly reflected in the introduction of new facilities which provide an integrated approach to sending messages to any combination of fax, telex and electronic mail addresses. See INFORMATION MANAGEMENT, NETWORKING.

Such a magnetic system acts as a magnetic collimator for decay electrons. Electrons whose momentum with respect to the axis are inside the solid angle [[theta].sub.C] can go through the magnetic plug field and reach the electron detector.
Because electron microscopy is not suitable for screening large numbers of samples, many alternate immunologic and molecular methods have been developed on the basis of nucleic acid amplification techniques.
For example, he figured that a dot's grip on an electron would nullify the motion-related subtleties that squelched the process at larger scales.
This field decrease serves to longitudinalize the charged particle trajectories and thus significantly reduce the systematic effects of electron Penning trapping.
[v.sub.e] is the beta electron velocity, and [[phi].sup.I](E) and [[phi].sup.II]([E.sub.e]) are geometrical factors [8].
The electrons travel to the oxygen, generating a current as they move from one chamber to the other.
Electrons and protons spiral around magnetic field lines and are guided to two 10 cm by 10 cm segmented Si detectors.
Watson Research Center in Yorktown Heights, N.Y., and Luc Berger of Carnegie Mellon University in Pittsburgh independently proposed a novel twist on the phenomenon: If electron spins are aligned within an electric current flowing through a magnet, they might exert torques large enough to reorient the magnetization of that magnet.
where the functions [g.sub.e]([[beta].sub.e],[E.sub.[gamma],min]) and [g.sub.p]([[beta].sub.e],[E.sub.[gamma],min]) describe the electron and proton contributions to the radiative branch respectively for [E.sub.[gamma]] > [E.sub.[gamma],min].
The delayed coincidence between proton and electron detection provides a powerful method for rejecting background photons that are not associated with a neutron decay.
This is one of the reasons that Daniel Geelen, Johannes Jobst, Sense Jan van der Molen and Rudolf Tromp use slow electrons, carrying low energies of several electron volts (eV, hence 'eV-TEM') instead of the usual tens or hundreds of thousands of electron volts.
The peak of electron density for E layer has a relationship with the angle of the sun where it increased at summer time.
