Evidence of non-thermal X-ray emission from HH 80

Protostellar jets appear at all stages of star formation when the accretion process is still at work. Jets travel at velocities of hundreds of km/s, creating strong shocks when interacting with interstellar medium. Several cases of jets have been detected in X-rays, typically showing soft emission. For the first time, we report evidence of hard X-ray emission possibly related to non-thermal processes not explained by previous models of the post-shock emission predicted in the jet/ambient interaction scenario. HH 80 is located at the south head of the jet associated to the massive protostar IRAS 18162-2048. It shows soft and hard X-ray emission in regions that are spatially separated, with the soft X-ray emission region situated behind the region of hard X-ray emission. We propose a scenario for HH 80 where soft X-ray emission is associated to thermal processes from the interaction of the jet with denser ambient matter and the hard X-ray emission is produced by synchrotron radiation at the front shock.Comment: Accepted for publication in ApJ

Runaway stars: their impact on the intestellar medium

Runaway, massive stars are not among the most numerous. However, the bow shocks built by their supersonic movement in the interstellar medium have been detected in the infrared range in many cases. Most recently, the stellar bow shocks have been proposed as particle acceleration sites, as radio data analysis at high angular resolution have shown. We present results of different manifestations of the stellar bowshock phenomenon, revealed from modern IR databases.Las estrellas masivas fugitivas no son de las más numerosas. Sin embargo, los bowshocks formados debido a su movimiento supersónico en el medio interestelar han sido detectados en el rango infrarrojo en muchos casos. Muy recientemente, estos bowshocks estelares fueron propuestos como sitios de aceleración de partículas, como lo sugiere el análisis de datos de alta resolución angular a bajas frecuencias de radio. Se presentan aquí resultados de distintas manifestaciones relacionadas con bowshocks estelares, revelados a partir de las bases de datos IR más modernas.Fil: Benaglia, Paula.

Evaluation of NSW Family and Carer Mental Health Program: Summary Report

The purpose of this report is to provide a summary of the Family and Carer Mental HealthProgram evaluation that was commissioned by the NSW Ministry of Health (the Ministry)and undertaken by the Centre for Health Service Development (CHSD), Australian HealthServices Research Institute (AHSRI), University of Wollongong. The study was completedbetween June 2020 and September 2021. Detailed information on all aspects of theevaluation were provided to the Ministry in two associated reports: an interim reportsubmitted in March 2021 and a final report in December 2021. The evaluation was conducted to better understand the achievements of the program and tocontribute to the evidence base for family and carers supporting people with mental healthissues. It is the first evaluation of the FCMHP since it commenced operating in 2005

Agroforestry landscapes and global change: landscape ecology tools for management and conservation

Forest ecosystems are impacted by multiple uses under the influence of global drivers, and where landscape ecology tools may substantially facilitate the management and conservation of the agroforestry ecosystems. The use of landscape ecology tools was described in the eight papers of the present special issue, including changes in forested landscapes due to agricultural and forestry activities, landscape changes due to recent intensification of agriculture, and the impacts of agroforestry as compared to natural forest ecosystems. Landscape ecology can improve the economic, environmental and social values of agroforestry, and this knowledge should help to develop new management alternatives for agroforestry. We believe that these papers will inform management at the landscape level, especially in agroforestry landscapes, offering new tools for management and conservation.EEA Santa CruzFil: Martínez Pastur, Guillermo José.

A complex relationship among chemical concentration, detection threshold and suprathreshold intensity of bitter compounds

Detection thresholds and psychophysical curves were established for caffeine, quinine-HCl (QHCl), and propylthiouracil (PROP) in a sample of 33 subjects (28 female mean age 24 &plusmn; 4). The mean detection threshold (&plusmn;standard error) for caffeine, QHCl, and PROP was 1.2 &plusmn; 0.12, 0.0083 &plusmn; 0.001, and 0.088 &plusmn; 0.07 mM, respectively. Pearson product&ndash;moment analysis revealed no significant correlations between detection thresholds of the compounds. Psychophysical curves were constructed for each bitter compound over 6 concentrations. There were significant correlations between incremental points of the individual psychophysical curves for QHCl and PROP. Regarding caffeine, there was a specific concentration (6 mM) below and above which the incremental steps in bitterness were correlated. Between compounds, analysis of psychophysical curves revealed no correlations with PROP, but there were significant correlations between the bitterness of caffeine and QHCl at higher concentrations on the psychophysical curve (P &lt; 0.05). Correlation analysis of detection threshold and suprathreshold intensity within a compound revealed a significant correlation between PROP threshold and suprathreshold intensity (r = 0.46&ndash;0.4, P &lt; 0.05), a significant negative correlation for QHCl (r = &ndash;0.33 to &ndash;0.4, P &lt; 0.05), and no correlation for caffeine. The results suggest a complex relationship between chemical concentration, detection threshold, and suprathreshold intensity.<br /
