An investigation of the spatial variations of the energetic trapped electrons at low altitudes.

We have analyzed the trapped electron data (0.19-3.2 MeV) taken by the Japanese OHZORA satellite operated at 350-850 km altitude in polar orbit during 1984-1987 near solar minimum. The electron observations reveal all the global attributes of the quiet-time electron radiation belts, such is the South Atlantic Anomaly, the electron "slot", and the outer radiation belt regions. The electron data are in general agreement with the NASA AE-8 electron model, but there are differences, particularly with respect to distinctive local-time variations in the slot region. In this paper, we present results from analyses of variations of the electron pitch angle distributions with local time, L-shell and altitude.

[Osteoid osteoma. 5 cases].

With reference to five cases of osteoid osteoma, including two para-articular cases with articular reaction, two cases with neurological manifestations, and one case with a rare costal lesion, the authors demonstrate the difficulty of diagnosis in this disease, which is, in principle, well known. In some cases the observations extended over seven years. The authors also review the literature on this subject.
