X-ray powder diffraction at the XRD1 beamline at LNLS

Various upgrades have been completed at the XRD1 beamline at the Brazilian synchrotron light source (LNLS). The upgrades are comprehensive, with changes to both hardware and software, now allowing users of the beamline to conduct X-ray powder diffraction experiments with faster data acquisition times and improved quality. The main beamline parameters and the results obtained for different standards are presented, showing the beamline ability of performing high-quality experiments in transmission geometry. XRD1 operates in the 5.5-14 keV range and has a photon flux of 7.8 × 10⁹ photons s^-1 (with 100 mA) at 12 keV, which is one of the typical working energies. At 8 keV (the other typical working energy) the photon flux at the sample position is 3.4 × 10¹⁰ photons s^-1 and the energy resolution ΔE/E = 3 × 10^-4.

Attention to process and clinical outcomes of implementing a rural school-based trauma treatment program

The Louisiana Rural Trauma Services Center was established to provide, improve, and enhance urgently needed assessment, treatment, crisis management, and consultation services for children and adolescents exposed to traumatic events in three rural southeastern Louisiana parishes. The purpose of this study is to describe the process of implementing the rural school-based trauma treatment program and to evaluate its effectiveness in 115 students. Through attention to process including the three-tiered approach of relationship building, trauma training, and trauma services, the school-based trauma treatment program proved effective in reducing trauma symptoms. This study is important to support the widespread implementation of school-based mental health services.
