... 371Gregory Taylor . ... We persent a catalog of 1274 discrete sources detected during a 5 yr, 6 cm, radio-patrol survey of the galactic plane for variavle sources. ... Seventy-five percent of the sources are weaker than 75 mJy, and as a consequence reliable sources and 27 possible variables were detected, of which 64 % exhibited shirt-term variability. ... A comparison with previous centimeter variability studies suggests the possible existence of two distinnct variability components. ...

Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby photometry and proper motion, and placed within 80 pc from the Sun. Components of space velocities, eccentricities of galactic orbits, perigalactic and apogalactic distances, and maximal remotness from galactic plane are presented for 1787 stars. ...

... The 7 and 15 um observations of selected fields in the Galactic Plane obtained with ISOCAM during the ISOGAL program offer an unique possibility to search for previously unknown YSOs, undetected by IRAS because of lower sensitivity or confusion problems. ... The main indications of the previous analysis are confirmed, but the criteria for selecting YSO candidates had to be revised to select only bright objects, in order to limit the contamination of the sample by Post-MS stars. ...

... We also present independent relationships between the visual surface brightness parameter FV and the colours (V \Gamma R), (V \Gamma I), (R \Gamma I) and (V \Gamma K). We find that (U \Gamma B) and (B \Gamma V ) are unsuitable as T eff indicators. The tightest relationship in each case is found for the (V \Gamma K) index. Our mean relationships agree reasonably well with similar relationships derived by other authors, where such are available. ...

X-ray techniques have been used to investigate single ZnS crystals grown according to Bridgman by vertical oriented crystallization under an argon pressure of 5-6 MPa. ... Some reflections show multiple diffraction. ... The model of the multiple diffraction, based on the assumption that the effect increases when the phase invariant is equal to zero, has been considered. This model describes the experiment satisfactorily. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...
