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. Emissão de óxido nitroso de estação de tratamento de esgoto de lodos ativados por aeração prolongada - estudo preliminar
Nitrous oxide emissions from an activated sludge plant which serves a research institute in Rio de Janeiro city were estimated from six unit processes (grit tank, sand trap, aeration tank, secondary settling tank, sludge recirculation line and aerobic digester sludge tank) and also from the plant effluent. Total estimated annual flux was 3.2 x 10(4) g N2O yr

3. Production and Vertical Flux of Attached Bacteria in the Hudson River Plume of the New York Bight as Studied with Floating Sediment Traps †
We investigated the growth and vertical flux of attached bacteria with floating sediment traps in the Hudson River Plume of the New York Bight during the spring diatom blooms. Traps were floated at the base of the mixed layer (ca. 10 m) for 1-day periods. After recovery, we measured bacterial abundance and rates of [methyl-3H]thymidine incorporation in the t

4. Monopoles and fractional vortices in chiral superconductors
I discuss two exotic objects that must be experimentally identified in chiral superfluids and superconductors. These are (i) the vortex with a fractional quantum number (N = 1/2 in chiral superfluids, and N = 1/2 and N = 1/4 in chiral superconductors), which plays the part of the Alice string in relativistic theories and (ii) the hedgehog in the ^l field, wh

5. Oxidative damage to brain proteins, loss of glutamine synthetase activity, and production of free radicals during ischemia/reperfusion-induced injury to gerbil brain.
Free radical-mediated oxidative damage has been implicated in tissue injury resulting from ischemia/reperfusion events. Global cortical ischemia/reperfusion injury to Mongolian gerbil brains was produced by transient occlusion of both common carotid arteries. Protein oxidation, as measured by protein carbonyl content, increased significantly during the reper
