At night, internal atmospheric gravity waves are able to induce drift instabilities in the ionospheric plasma. Nighttime constant height type sporadic-E(Esc) may then be explained as an effect due to the combined effect of ionization movement due to the wind shear mechanism and due to the cross-field gradient drifts.

Conjugate Sporadic-E measurements
Journal of Atmospheric and Solar-Terrestrial Physics, 2009Abstract During an equatorial campaign called COPEX (Conjugate Point Equatorial Experiment) ionosondes at a pair of conjugate stations in Brazil were operated for 2 months in 2002. One expected the sporadic-E (E s ) layers to be rather similar at the conjugate locations.

Acute sporadic hepatitis E in Kuwait
Journal of Medical Virology, 1994AbstractFifty‐seven adult patients with acute hepatitis and 34 comparison patients without liver disease were evaluated using a newly developed Western blot assay for IgM antibody to hepatitis E virus. The mean age of patients with hepatitis was 32 years (range, 18‐55 years); 88% were male. Among patients with acute hepatitis, hepatitis A (anti‐HAV IgM

Sporadic E-layers as current generators
Radiophysics and Quantum Electronics, 1996Quasi two- and three-dimensional models of dense night-time sporadic E-layers of the earth's ionosphere as current generators are developed. The layers are assumed to be situated in an ambient plasma of about fifty times lower density and their neutral particles possess a rather high bulk velocity relative to the ions.

Sporadic Hepatitis E in Austria
New England Journal of Medicine, 1998To the Editor: The hepatitis E virus (HEV) is known to cause enterically transmitted epidemic and sporadic forms of hepatitis in tropical and subtropical countries. HEV has been reported occasionally in areas where the disease is not endemic1; however, such infections are predominantly associated with a history of travel to tropical or subtropical ...

Abstract Studies of sporadic E clouds indicate that the modal station separation at time of radio contact was 1,490 km, 2,800 km, and about 4,200 km for single, double- and triple-hop communication. Large E 3 clouds having an effective diameter of about 925 km were found to be fairly prevalent.

Continental sporadic E activity
Eos, Transactions American Geophysical Union, 1951Sporadic E ionizations indicated a very interesting motion or drift during the period June 17–18, 1949, over North America. The reflections were reported from 23h00m GMT on the 17th to 05h00m GMT on the 18th, by radio amateurs operating mainly in the frequency range 50–54 mc/s.
