Fusion target designed to match present relativistic electron beam machine parameters
The range of parameters considered for this design were restricted to beam voltages of 1 MeV and pulse widths of 50 ns, with zero rise and fall time. Total beam energy was varied from 10 kJ to 100 kJ. Descriptions are given of the target and electron deposition. Computer calculations are given of electron beam heating of the fuel
History of clinical transplantation
How transplantation came to be a clinical discipline can be pieced together by perusing two volumes of reminiscences collected by Paul I. Terasaki in 1991-1992 from many of the persons who were directly involved. One volume was devoted to the discovery of the major histocompatibility complex (MHC), with particular reference to the human leukocyte antigens (HLAs) that are widely used today for tissue matching.1 The other focused on milestones in the development of clinical transplantation.2 All the contributions described in both volumes can be traced back in one way or other to the demonstration in the mid-1940s by Peter Brian Medawar that the rejection of allografts is an immunological phenomenon.3,4 © 2008 Springer New York
