The expansion of an isolated hot spherical nucleus with excitation energy and its caloric curve are studied in a thermodynamic model with the SkM∗ force as the nuclear effective two-body inter-action. The calculated results are shown to compare well with the recent experimental data from energetic nuclear collisions. The fluctuations in temperature and density are also studied. They are seen to build up very rapidly beyond an excitation energy of ∼9 MeV/u. Volume-conserving quadrupole deformation in addition to expansion indicates , however, nuclear disassembly above an excitation energy of ∼4 MeV/u.

A study by the Office of Technology Assessment (OTA) that looks at nuclear proliferation and "seeks to facilitate an understanding of the problem and its implications, in terms of both a comprehensive overview and a detailed indepth analysis of key elements" (p. 7).

A medicina nuclear permite estudar o fígado segundo várias perspectivas, usando métodos de simples execução. A captação de radiocoloides pelas células de Küpffer informa sobre a situação funcional destas células e fornece indicações sobre a circulação hépatica eficaz. Por outro lado, os mais recentes derivados do ácido imino-diacético, marcados com Tecnécio-99m (v.g. trimetiliodo –IDA-99m TC e trimetilbromo –IDA-99m TC) possibilitam uma adequada avaliação das funções de captação hepatocitária e de excreção biliar. O grande desenvolvimento que se tem verificado nas potencialidades informáticas dos equipamentos de medicina nuclear contribui para que a quantificação de parâmetros funcionais seja um procedimento frequente em muitas das suas técnicas (v.g. cintigrafia renal, ventriculografia de radionúclidos). Neste trabalho procuramos cont...
