1. Caracterização dos campos neutrônicos obtidos por meio de armadilha de nêutrons no interior do núcleo do reator nuclear IPEN/MB-01 / Neutronic characterization of the fields obtained by means of neutron traps inside the nuclear reactor core IPEN/MB-01
Este trabalho apresenta os resultados dos valores de fluxo de nêutrons obtidos a partir da implantação de uma armadilha de nêutrons no núcleo do Reator IPEN/MB-01. Foram analisadas várias configurações de armadilhas implantadas no núcleo do reator IPEN/MB-01 de forma a se eleger a armadilha mais eficiente. Para a caracterização energética, foram

2. Measurements of the neutron spectrum energy in the IPEN/MB-01 reactor core
This work presents the results of neutron spectrum measurements at central position of the IPEN/MB-01 reactor core. For this purpose has been used several activation foils (Au, Sc, U, Mg, Ti, Ni, and In Foils) that have been irradiated at central position of the reactor core (standard rectangular configuration 28 × 26 fuel rods) in the maximum power level (

3. Calibração dos canais nucleares do Reator IPEN/MB-01, obtida a partir da medida da distribuição espacial do fluxo de nêutrons térmicos no núcleo do reator através da irradiação de folhas de ouro infinitamente diluídas / CALIBRATION OF THE NUCLEAR POWER CHANNELS OF THE IPEN/MB-01 REACTOR OBTAINED FROM THE MEASUREMENTS OF THE SPATIAL THERMAL NEUTRON FLUX DISTRIBUTION IN THE REACTOR CORE THROUGH THE IRRADIATION OF INFINITELY DILUTED GOLD FOILS
Several nuclear parameters are obtained through the gamma spectrometry of targets irradiated in a research reactor core and this is the case of the activation foils which make possible, through the measurements of the activity induced, to determine the neutron flux in the place where they had been irradiated. The power level operation of the reactor is a par

4. Caracterização do campo de nêutrons na instalação para estudo em BNCT no Reator IEA-R1 / NEUTRON FIELD CHARACTERIZATION IN THE INSTALLATION FOR BNCT STUDY IN THE IEA R1 REACTOR.
This work aims to characterize the mixed neutron and gamma field, in the sample irradiation position, in a research installation for Boron Neutron Capture Therapy (BNCT), in the IPEN IEA-R1 reactor. The BNCT technique has been studied as a safe and selective option in the treatment of resistant cancerigenous tumors or considered non-curable by the convention

5. The Hippocampus and Memory of Verbal and Pictorial Material
Recognition of words and kaleidoscope pictures showed a double dissociation of left and right hippocampal activity using magnetic source imaging (MSI). MSI has advantages over alternative imaging techniques that measure hemodynamic changes for identifying regional changes in brain activity in real time and on an individual subject basis without the need for
