... The C III] multiplet near 1908? has a transition at 1909.6? completely forbidden in C, but allowed as a result of the non-zero nuclear spin of C. The C III] line was observed with the GHRS and Echelle-B and a positive detection of the C line was made in the Galactic C-rich PN NGC 3918; a marginal detection of the C line was made in SMC N2, which is also C rich. ... The derived C/ C ratio is 15 3. For SMC N2 the C line is much weaker and a 2 detection was made: the C/ C ratio was measured as 21. ...

Abstract . A first-generation CMOS Charged Particle Spectrometer chip [1] was designed at JPL for flight on the STRV-2 spacecraft. These devices will collect electron and proton spectra in low Earth orbit as part of an experiment to demonstrate Active Pixel Sensor (APS) technology in space. This paper presents the results of total dose testing on these chips and, where possible, attempts to extend the results to other Active Pixel Sensors. ...

It is necessary to select a topic interesting from scientific point of view and simple enough to allow students understand and participate in all stages of experiment from measurements via data analysis to physical inference. ... Solar modulation effects and physical characteristics and analysis of the major solar events are possible only by joining data from space-born and surface particle and radiation detectors. ...

... 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. ...

... For this paper: postscript PPEUC CMB index 1 Introduction.. ... We report on a 16 ks X-ray observation with the ROSAT PSPC towards the center of a CMB decrement detected by Jones et al. (1997) in the direction of the quasar pair PC1643+4631 A & B. At the position of the decrement we find no evidence for emission by hot gas which could give rise to the Sunyaev-Zel'dovich effect. ... We conclude that the CMB decrement is not a typical galaxy cluster. ... 2 The ROSAT PSPC observation . ...
