This review deals with applications of activation analysis to geological samples : , minerals and rocks . The various activation sources suitable for tb.is purpose are discussed. Applications using isotopic neutron sources are reviewed in some detail , those using neutron generators are discussed on a rrore general basis . Present trends in instrumental neutron-activation techniques are briefly...

The particle-flow reconstruction algorithm aims at providing a global (i.e., complete and unique) event description at the level of individually reconstructed particles, with an optimal combination of the information coming from all CMS subdetectors. The reconstructed and identified individual particle list includes muons, electrons (with individual reconstruction and identification of all Brem...

The second modern synthesis of biology [1] must start with new stratifications and conceptualizations, as well as new ways to connect all of them [2], which are to be perfected through in-depth discussions that may be provoked by seemingly controversial ideas. And new paradigms can thus be built upon the novel thoughts that may eventually converge. As knowledge accumulates based on either newly...

Following the grounding and subsequent explosion, in October 2003, of a nuclear submarine in the waters of the La Maddalena National Marine Park, fears arose of possible radioactive leakages. However, isotopic analyses on algae showed that the gamma-ray emitting artificial radionuclides that one might expect to leak from a damaged nuclear reactor (such as U-235, I-131, Cs-137) were absent, and ...
