Particle Acceleration in Galactic Supernova Remnants,ion. Young, bright shell remnants generally have spectral indices α larger than the 0.5 expected from basic shock acceleration theory. Fainter, older shell remnants have a wide range of α. Evidence on whether or not particle acceleration is continuing in SNRs is also discussed.

VHE and UHE Gamma Ray Observations by Ground Based Detectors,ht produced by the cascade particles in the earth’s atmosphere can be received at ground. For energies greater than 10. eV the particles of the cascade can be measured by detector arrays. The flux sensitivities of typical installations are presented.

Living-Donor Liver Transplantation in TaiwanThe quartet of isotopes of hydrogen(H) and helium(He) are the four most abundant species in the arriving cosmic radiation. In this paper, a brief summary of the spectra snd propagation of these species is given. The reader is referred to Beatty (1986) for a more detailed discussion.

Preference Revelation and Public Goods,Recent γ-ray studies of the distribution of cosmic rays throughout the Galaxy are discussed based on the observations obtained with the .-2 .-B satellites. For reasons addressed in this paper the picture arising from recent analyses of both data bases differs from the one generally advocated in the past.

An Overview of Cosmic Ray Research: Composition, Acceleration and Propagation,An overview of Cosmic Ray Research and its relation to other areas of High Energy Astrophysics is presented. Particular attention is paid to providing a summary of current results on the composition, acceleration and propagation of the cosmic radiation — topics which will be discussed in greater detail in other papers in this volume.
