Sobre IBD

Domestic expertise in the separation of rare earth elements, as well as the large reserves of these minerals in Brazil, motivated the study of domestic neutron-converting scintillator screens, using a granular mixture of Gd2O3-ZnS:Ag. Three methodologies were used to manufacture these screens, namely: blasting with a compressed air gun on a sheet of CG3460-3M cellulose; melting of the granular mixture, Gd2O3-ZnS:Ag with EVA in a mixing chamber; and deposition of the granular mixture on the EVA substrate. A flux of approximately 4.46x105 thermal neutrons/cm2.s was used, coming from the J-9 irradiation channel of the Argonauta/IEN/CNEN reactor.

    Calabi-Yau spaces are complex spaces with a vanishing first Chern class, or equivalently, with trivial canonical bundle (canonical class). They are used to construct possibly realistic (super)string models and are thus being studied vigorously in the recent physics literature.In the main part of the Book, collected and reviewed are relevant results on (1) several major techniqu...

    There are a number of unanswered questions which indicate that the Standard Model, successful as it is, cannot be the entire story. One solution to answering these questions is that the Standard Model is an effective low-energy theory of structure hopefully nearby in its energy scale in much the same way that a model of strong interactions among nucleons mediated by pions is an...
