High-resolution XEOL spectroscopy setup at the X-ray absorption spectroscopy beamline P65 of PETRA III.

A newly designed setup to perform steady-state X-ray excited optical luminescence (XEOL) spectroscopy and simultaneous XEOL and X-ray absorption spectroscopy characterization at beamline P65 of PETRA III is described. The XEOL setup is equipped with a He-flow cryostat and state-of-the-art optical detection system, which covers a wide wavelength range of 300-1700 nm with a high spectral resolution of 0.4 nm. To demonstrate the setup functioning, low-temperature XEOL studies on polycrystalline CuInSe2 thin film, single-crystalline GaN thin film and single-crystalline ZnO bulk semiconductor samples are performed.

Experiencing multiple loss of persons with AIDS: grief and bereavement issues.

Through a case study approach involving seven respondents and intensive personal interviews, the authors explored grief and bereavement issues for survivors experiencing multiple loss of persons with acquired immune deficiency syndrome (AIDS). A three-stage model of grief including avoidance, confrontation, and reestablishment was used to explore the issues faced by survivors. The compounding factors of this phenomenon include society's unwillingness to validate the gay identity, the intensity of multiple loss, the lack of time between losses, and the subsequent impact on self-identify and self-esteem. These discussions serve to enable an understanding of the grief experience for this population. Recommendations for practice are given to facilitate the expression of feelings necessary for the healing process to begin.
