The debate between proponents of a static corona, Parker's solar wind theory, and an alternative "solar breeze" theory of Chamberlai n [1960, 1961; Dessler 1967] was only settled by observations from space. ... Rapidly spreading plasma clouds produced by solar flares, like those envisioned by Chapman and Ferraro, are sometimes superposed on the solar wind flow. ...

... On a possible reason of T c suppression with oxygen doping in Tl 2 Ba 2 CuO 6+x. Abstract: . Magnetic susceptibility and 63 Cu and 205 Tl nuclear spin-lattice relaxation rates have been measured in Tl 2 Ba 2 CuO 6+x high- temperature superconductor to establish the mechanism of decreasing the transition temperature with oxygen doping. The experiments have revealed the presence of localized paramagnetic centers (LPC) whose concentration grown with increasing oxygen content. ...

... We revised topographical data obtained for the region to construct a generalized structure of the SPA basin as ringed formation. ... Because of our previous analysis of the ring structure [5, 6] we assumed the projection center o o coordinates as 180 W and 40 S. The hypsografic map shown in Fig. 1 demonstrates a hemisphere of the Moon which contains the SPA basin structure and its environs. ... Then we find the o o basin outermost ring center at roughly 180 and 40 S. Inner structure of the SPA basin...
