Results of the August 1977 Soviet and American meterological rocketsonde intercomparison held at Wallops Island, Virginia
A coordinated program of rocketsonde investigations along about 60 deg E and 70 deg W between the United States and U.S.S.R. is discussed. The rocketsonde instruments used by the U.S. and U.S.S.R. were compared and the results are presented. The U.S. Super Loki Datasonde and the U.S.S.R. M100B rocketsonde are discussed. Results indicate that the U.S/U.S.S.R. rocketsonde measurement agreement improved since the 1973 intercomparisons. It was learned that the mean of the differences of the temperatures compare to within 6 C at about 60 km and to within 2 C near 50 km. Wind measurements were also found to agree
Band structure of (Sr3Sc2O5)Fe2As2 as a possible parent phase for new FeAs superconductors
By means of first-principles FLAPW-GGA calculations, we have investigated the
electronic properties of the newly synthesized layered phase -
(Sr3Sc2O5)Fe2As2. The electronic bands, density of states and Fermi surface
have been evaluated. The resembling of our data for (Sr3Sc2O5)Fe2As2 with band
structure pictures of known FeAs superconducting materials may be considered as
the theoretical background specifying the possibility for (Sr3Sc2O5)Fe2As2 to
become a parent phase for new FeAs superconductors.Comment: 10 pages, 4 figures, 3 table
