We present results from time-of-flight nuclear mass measurements at the National Superconducting Cyclotron Laboratory that are relevant for neutron star crust models. The masses of 16 neutron-rich nuclei in the scandium-nickel range were determined simultaneously, with the masses of 61V, 63Cr, 66Mn, and 74Ni measured for the first time with mass excesses of -30.510(890)MeV, -35.280(650)MeV, -36.900(790) MeV, and -49.210(990)MeV, respectively. With these results the locations of the dominant electron capture heat sources in the outer crust of accreting neutron stars that exhibit super bursts are now experimentally constrained. We find the experimental Q value for the 66Fe→ 66Mn electron capture to be 2.1 MeV (2.δ) smaller than predicted, resulting in the transition occurring significantly closer to the neutron star surface.

Background: The influence of the physical environment on patient falls has not been fully explored in psychiatric units, despite this patient population's vulnerability and the critical role of the physical environment in patient safety., Aims: The research objective is to describe the spatial and temporal pattern of falls occurrences and their location in relation to the levels of safety continuum model., Method: This article presents an exploratory case study design. Seven years of retrospective data on patient falls, yielding 818 sentinel events, in an 81-bed psychiatric hospital in the United States were collected and analyzed. Data focused on extrinsic factors for falls, emphasizing the physical environment. Through a content analysis of the sentinel event narratives, recorded by the hospital staff, this study explored patient falls related to location and elements of the physical environment., Results: The analysis revealed that 15% of recorded falls were attributed to some aspect of or element within the physical environment. The most typical locations of falls were patient rooms (39%), patient bathrooms (22%), and dayrooms (20%). Also, the results identified patterns of environmental factors that appeared linked to increasing patients' susceptibility to falls. Risk factors included poor nighttime lighting, flooring surfaces that were uneven, and spaces that inadvertently limited visual access and supervision., Conclusions: The physical environment plays an often-unexamined role in fall events and specific locations. These results are deserving of further research on design strategies and applications to reduce patient falls in psychiatric hospital settings.

Tribal groups work tirelessly to maintain sovereignty rights, preserving and upholding tribal authority and protection over their land, people, businesses, and health. Moreover, the conduct of health science research by outsiders has had its share of an unethical, misguided, and abusive past. Tribally based institutional review boards (IRBs) are addressing these issues in an effort to control new health science research, set their own research agenda, and protect their people in the same spirit as has been accomplished through the perpetuation of sovereignty rights. We describe the success of a tribally based IRB at creating new capacity for health research and enhanced levels of trust, including bidirectional cultural education between academic researchers and tribal IRB committee members.
