Efectividade da Rede de Referenciação Perinatal da Região Centro

Resumo Em 1990 foi desenvolvida em Portugal uma Rede de Referenciação Perinalal, com definição dos limites e as responsabilidades assistenciais dos Hospitais de Apoio Perinatal Diferenciado (HAPD) e dos Hospitais de Apoio Perinatal (HAP). Graças ao espírito de cooperação c complementaridade desenvolvidos, os critérios de transferência iu útero e pós natal estão bem estabelecidos* Com os resultados do Registo Na...

Clinical experience in invasive fungal infections

Lung infections caused by invasive filamentous fungi are very rare conditions in AIDS, but must be considered in patients with profound immune suppression especially in the presence of additional risk factors, such as hematologic malignancies, corticosteroid therapy, neutropenia, and chemotherapy. The authors report a case of dual lung infection caused by Aspergillus and Mucor, which occurred in a 34-year-old A...

Razões para alteração da terapêutica antiretrovírica: retrospectiva de cinco anos

Hemoperfusão com carvão activado na intoxicação grave por carbamazepina

RESUMO Caso clínico: Os autores apresentam o caso de uma adolescente admitida no Serviço de Urgência por alterações neurológicas de início agudo e progressivas, existindo na residência um familiar medicado com um antiepiléptico. A avaliação inicial revelou sonolência, discurso adequado, disartria, nistagmo, dismetria bilateral e ataxia da marcha. Foi efectuado doseamento sérico de carbamazepina, que revelou val...

Status and outlook of the neutron time-of-flight facility n_TOF at CERN

The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight burst result in a much enhanced signal to background ratio for neutron capture of radioactive isotopes and makes this facility well suited for the measurement of high quality neutron-induced rea...

Neutron reactions and nuclear cosmo-chronology

The [beta]-decay of 187Re represents a suited cosmo-chronometer for the age of the r-process abundances, since the radiogenic part of the daughter isotope 187Os is defined by the difference between the solar 187Os abundance and s-process contribution to 187Os. The latter component can be determined via the s-process systematics based on the stellar neutron capture cross sections of 186Os and 187Os. The laborato...

Neutron capture cross section measurements for nuclear astrophysics at CERN n_TOF

A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n_TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton beam driver, the extremely high instantaneous neutron flux, and the low background conditions in the experimental area are optimal for capture cross section measurements on low-mass or radioac...

A low-mass neutron flux monitor for the n _TOF facility at CERN

A small-mass system has been developed for monitoring the flux of neutrons with energy up to 1 MeV at the new time-of-flight facility at CERN, n_TOF. The monitor is based on a thin Mylar foil with a 6Li deposit, placed in the neutron beam, and an array of Silicon detectors, placed outside the beam, for detecting the products of the 6Li(n, alpha)³H reaction. The small amount of material on the beam ensures a min...

Measurement of the n_TOF beam profile with a micromegas detector

A Micromegas detector was used in the neutron Time-Of-Flight (n_TOF) facility at CERN to evaluate the spatial distribution of the neutron beam as a function of its kinetic energy. This was achieved over a large range of neutron energies by using two complementary processes: at low energy by capture of a neutron via the 6Li(n,[alpha])t reaction, and at high energy by elastic scattering of neutrons on gas nuclei ...
