New infrared star clusters in the Northern and Equatorial Milky Way with 2MASS

We carried out a survey of infrared star clusters and stellar groups on the 2MASS J, H and K_s all-sky release Atlas in the Northern and Equatorial Milky Way (350 < l < 360, 0 < l < 230). The search in this zone complements that in the Southern Milky Way (Dutra et al. 2003a). The method concentrates efforts on the directions of known optical and radio nebulae. The present study provides 167 new infrared clusters, stellar groups and candidates. Combining the two studies for the whole Milky Way, 346 infrared clusters, stellar groups and candidates were discovered, whereas 315 objects were previously known. They constitute an important new sample for future detailed studies.Comment: Accepted to Astronomy and Astrophysic

Early childhood adversities and trajectories of psychiatric problems in adoptees: Evidence for long lasting effects

The aim of the present study is to investigate whether early childhood adversities determine the longitudinal course of psychiatric problems from childhood to adulthood; in particular if the impact of early maltreatment on psychopathology decreases as time passes. A sample of 1,984 international adoptees was followed (955 males and 1029 females; adopted at the mean age of 29 months). Parents provided information about abuse, neglect and numbe

New infrared star clusters in the southern Milky Way with 2MASS

We carried out a 2MASS J, H and K_s survey of infrared star clusters in the Milky Way sector 230$^{\circ}$ $< \ell <$ 350$^{\circ}$. This zone was the least studied in the literature, previously including only 12 infrared clusters or stellar groups with $|b|<$ 10$^{\circ}$, according to the recent catalogue by Bica et al. (2003). We concentrated efforts on embedded clusters, which are those expected in the areas of known radio and optical nebulae. The present study provides 179 new infrared clusters and stellar groups, which are interesting targets for detailed future infrared studies. The sample of catalogued infrared clusters and stellar groups in the Galaxy is now increased by 63%.Comment: 8 pages, 10 figures, accepted to A&A. Tables 3 and 4 available in eletronic form at CD

The mental health of populations directly and indirectly exposed to violent conflict in Indonesia

Background Large disasters affect people who live both near and far from the areas in which they occur. The mental health impact is expected to be similar to a ripple effect, where the risk of mental health consequences generally decreases with increasing distance from the disaster center. However, we have not been able to identify studies of the ripple effect of man-made disaster on mental health in low-income countries. Objectives The objective was to examine the hypothesis of a ripple effect on the mental health consequences in populations exposed to man-made disasters in a developing country context, through a comparison of two different populations living in different proximities from the center of disaster in Mollucas. Methods Cross-sectional longitudinal data were collected from 510 Internally Displaced Persons (IDPs) living in Ambon, who were directly exposed to the violence, and non-IDPs living in remote villages in Mollucas, Indonesia, who had never been directly exposed to violence in Mollucas. Data were collected during home visits and statistical comparisons were conducted by using chi square tests, t-test and logistic regression. Results There was significantly more psychological distress "caseness" in IDPs than non-IDPs. The mental health consequences of the violent conflict in Ambon supported the ripple effect hypothesis as displacement status appears to be a strong risk factor for distress, both as a main effect and interaction effect. Significantly higher percentages of IDPs experienced traumatic events than non-IDPs in all six event types reported. Conclusions This study indicates that the conflict had an impact on mental health and economic conditions far beyond the area where the actual violent events took place, in a diminishing pattern in line with the hypothesis of a ripple effect

Radiation Doses to Patients and Personnel Involved in Embolization of Intracerebral Arteriovenous Malformations

Radiation doses to patients and personnel were measured during 5 embolization procedures in 5 different patients. Thermoluminescent dosimeters were used to measure the absorbed doses in different points of the skin of patients as well as personnel. A transmission ionization chamber was used to determine the energy imparted in the patients. The effective dose equivalent HE during the procedures was estimated to be in the range of 6 to 43 mSv to the patients, 10 to 26 μSv to the radiologist in charge of the embolizations, 3 to 24 μSv to the assisting radiographer and 13 to 86 μSv to the nurse anesthetist. Radiation doses to the patients were considerable but the estimated risks from radiation were low compared to the risks of the arteriovenous malformation itself and the hazards of the embolization. The annual radiation doses to the personnel were well below established dose limits. </jats:p
