Neutron radiation effects on an electronic system on module.

The NUMEN (NUclear Matrix Elements for Neutrinoless double beta decay) project was recently proposed with the aim to investigate the nuclear response to Double Charge Exchange reactions for all the isotopes explored by present and future studies of 0νββ decay. The expected level of radiation in the NUMEN experiment imposes severe limitations on the average lifetime of the electronic devices. During the experiments, it is expected that the electronic devices will be exposed to about 10 neutrons/cm/s according to FLUKA simulations.

SAFIIRA: A heavy-ion multi-purpose irradiation facility in Brazil.

This work describes the new facility for applied nuclear physics at the University of Sao Paulo, mainly for irradiation of electronic devices. It is a setup composed of a quadrupole doublet for beam focusing/defocusing plus multiple scattering through gold foils to produce low intensity, large-area, and high-uniformity heavy-ion beams from H to Ag. Beam intensities can be easily adjusted from 10 particles cm/s to hundreds of nA for an area as large as 2.

Adolescents with attention deficit hyperactivity disorder and exposure to violence: parents' opinion.

Objective: To identify the opinion of parents or guardians of adolescents diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) about their children's exposure as perpetrators or victims of violence situations in family life or outside.

Method: Qualitative study with use of thematic oral history. Nine parents of 07 adolescents with ADHD participated.

Moderating effects of empathic concern and personal distress on the emotional reactions of disaster volunteers.

This study examines stress and mood outcomes in community volunteers who undertook one week's worth of post-disaster relief work in L'Aquila, Italy, which had been hit by an earthquake four months earlier. The study team obtained pre- and post-relief work data from 130 volunteers involved in activities such as preparing food for the displaced, cleaning the camps and distributing clean linen. The Perceived Stress Scale, the State-Trait Anxiety Inventory and the Profile of Mood States were administered at the start and at the end of the aid activities.
