- Critical measurements for understanding accretion and the dust/gas ratio in the solar nebula, where planets were forming 4.5 billion years ago, are being obtained by the GIADA (Grain Impact Analyser and Dust Accumulator) experiment on the European Space Agency's Rosetta spacecraft orbiting comet 67P/Churyumov-Gerasimenko. Between 3.6 and 3.4 astronomical units inbound, GIADA and OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) detected 35 outflowing grains of mass 10(-10) to 10(-7) kilograms, and 48 grains of mass 10(-5) to 10(-2) kilograms, respectively. Combined with gas data from the MIRO (Microwave Instrument for the Rosetta Orbiter) and ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instruments, we find a dust/gas mass ratio of 4 +/- 2 averaged over the sunlit nucleus surface. A cloud of larger grains also encircles the nucleus in bound orbits from the previous perihelion. The largest orbiting clumps are meter-sized, confirming the dust/gas ratio of 3 inferred at perihelion from models of dust comae and trails.

- BACKGROUND: In 2003, the Task Force on Quality Control of Disaster Management (WADEM) published guidelines for evaluation and research on health disaster management and recommended the development of a uniform data reporting tool. Standardized and complete reporting of data related to disaster medical response activities will facilitate the interpretation of results, comparisons between medical response systems and quality improvement in the management of disaster victims.METHODS: Over a two-year period, a group of 16 experts in the fields of research, education, ethics and operational aspects of disaster medical management from 8 countries carried out a consensus process based on a modified Delphi method and Utstein-style technique.RESULTS: The EMDM Academy Consensus Group produced an Utstein-style template for uniform data reporting of acute disaster medical response, including 15 data elements with indicators, that can be used for both research and quality improvement.CONCLUSION: It is anticipated that the Utstein-style template will enable better and more accurate completion of reports on disaster medical response and contribute to further scientific evidence and knowledge related to disaster medical management in order to optimize medical response system interventions and to improve outcomes of disaster victims.

Tidskriftsartikel (refereegranskat)abstract
- Unacceptable practices in the delivery of international medical assistance are reported after every major international disaster; this raises concerns about the clinical competence and practice of some foreign medical teams (FMTs). The aim of this study is to explore and analyze the opinions of disaster management experts about potential deficiencies in the art and science of national and FMTs during disasters and the impact these opinions might have on competency-based education and training.

- OBJECTIVE: Hospitals are expected to function as a safe environment during disasters, but many become unusable because of nonstructural damage. This study compares the nonstructural safety of hospitals to disasters in Tehran and Stockholm.METHODS: Hospital safety in Tehran and Stockholm was assessed between September 24, 2012, and April 5, 2013, with use of the nonstructural module of the hospital safety index from the World Health Organization. Hospital safety was categorized as safe, at risk, or inadequate.RESULTS: All 4 hospitals in Stockholm were classified as safe, while 2 hospitals in Tehran were at risk and 3 were safe. The mean nonstructural safety index was 90% ± 2.4 SD for the hospitals in Stockholm and 64% ± 17.4 SD for those in Tehran (P = .014).CONCLUSIONS: The level of hospital safety, with respect to disasters, was not related to local vulnerability. Future studies on hospital safety should assess other factors such as legal and financial issues. (Disaster Med Public Health Preparedness. 2014;0:1-6).

The Comet Interceptor Mission
- 2024

Ingår i: Space Science Reviews. - : Springer Nature. - 0038-6308 .- 1572-9672. ; 220:1
-
Tidskriftsartikel (refereegranskat)abstract
- Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the exploration of a little-processed long-period comet, possibly entering the inner Solar System for the first time, or to encounter an interstellar object originating at another star. The objectives of the mission are to address the following questions: What are the surface composition, shape, morphology, and structure of the target object? What is the composition of the gas and dust in the coma, its connection to the nucleus, and the nature of its interaction with the solar wind? The mission was proposed to the European Space Agency in 2018, and formally adopted by the agency in June 2022, for launch in 2029 together with the Ariel mission. Comet Interceptor will take advantage of the opportunity presented by ESA’s F-Class call for fast, flexible, low-cost missions to which it was proposed. The call required a launch to a halo orbit around the Sun-Earth L2 point. The mission can take advantage of this placement to wait for the discovery of a suitable comet reachable with its minimum Δ V capability of 600 ms − 1 . Comet Interceptor will be unique in encountering and studying, at a nominal closest approach distance of 1000 km, a comet that represents a near-pristine sample of material from the formation of the Solar System. It will also add a capability that no previous cometary mission has had, which is to deploy two sub-probes – B1, provided by the Japanese space agency, JAXA, and B2 – that will follow different trajectories through the coma. While the main probe passes at a nominal 1000 km distance, probes B1 and B2 will follow different chords through the coma at distances of 850 km and 400 km, respectively. The result will be unique, simultaneous, spatially resolved information of the 3-dimensional properties of the target comet and its interaction with the space environment. We present the mission’s science background leading to these objectives, as well as an overview of the scientific instruments, mission design, and schedule.

Forskningsöversikt (refereegranskat)abstract
- Hospitals need to be fully operative during disasters. It is therefore essential to be able to evaluate hospital preparedness. However, there is no consensus of a standardized, comprehensive and reliable tool with which to measure hospital preparedness. The aim of the current study was to perform a systematic review of evaluation tools for hospital disaster preparedness. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words "crisis," "disaster," "disaster medicine," "emergency," "mass casualty," "hospital preparedness," "hospital readiness," "hospital assessment," "hospital evaluation," "hospital appraisal," "planning," "checklist," and "medical facility" were used in combination with the Boolean operators "OR" and "AND." PubMed (National Library of Medicine, Bethesda, MD), ISI Web of Science (Thomson Reuters, New York, NY), and Scopus (Elsevier, New York, NY) were searched. A total of 51,809 publications were screened. The following themes were required for relevance: logistics, planning, human resources, triage, communication, command and control, structural and nonstructural preparedness, training, evacuation, recovery after disaster, coordination, transportation, surge capacity, and safety. The results from 15 publications are presented. Fifteen articles fulfilled the criteria of relevance and considered at least 1 of the 14 predetermined themes. None of the evaluated checklists and tools included all dimensions required for an appropriate hospital preparedness evaluation. The results of the current systematic review could be used as a basis for designing an evaluation tool for hospital disaster preparedness.

Tidskriftsartikel (refereegranskat)abstract
- Disaster response demands a large workforce covering diverse professional sectors. Throughout this article, we illustrate the results of a systematic review of peer-reviewed studies to identify existing competency sets for disaster management and humanitarian assistance that would serve as guidance for the development of a common disaster curriculum. A systematic review of English-language articles was performed on PubMed, Google Scholar, Scopus, ERIC, and Cochrane Library. Studies were included if reporting competency domains, abilities, knowledge, skills, or attitudes for professionals involved disaster relief or humanitarian assistance. Exclusion criteria included abstracts, citations, case studies, and studies not dealing with disasters or humanitarian assistance. Thirty-eight papers were analyzed. Target audience was defined in all articles. Five references (13%) reported cross-sectorial competencies. Most of the articles (81.6%) were specific to health care. Eighteen (47%) papers included competencies for at least 2 different disciplines and 18 (47%) for different professional groups. Nursing was the most widely represented cadre. Eighteen papers (47%) defined competency domains and 36 (94%) reported list of competencies. Nineteen articles (50%) adopted consensus-building to define competencies, and 12 (31%) included competencies adapted to different professional responsibility levels. This systematic review revealed that the largest number of papers were mainly focused on the health care sector and presented a lack of agreement on the terminology used for competency-based definition.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study was to identify the possible needs for undergraduate disaster medicine education in Sweden and to make informed recommendations for the implementation of disaster medicine content in medical and nursing schools in Sweden.An online survey was distributed to undergraduate medical and nursing students through the directors of all medical and nursing programs at Swedish universities. The survey contained demographic questions, as well as questions about the amount of disaster medical education and previous experience with rescue, police, or military services. The final survey page contained self-assessments of disaster medical knowledge. Comparative statistics were applied between nursing and medical students, those with previous military service, and those without, as well as between universities.A total of 500 medical and 408 nursing students participated in this study. A median of 2 h of disaster medicine education was provided to senior medical students and 4 h was provided to senior nursing students. Senior medical students scored their disaster medical knowledge lower than nursing students (t-test, p < 0.001). A proportion of 1% had served in rescue services or police, and 7% of the participants had a history of military service, of which 67% served in a medical role. Those who had served in rescue services, police, or the armed forces had a higher self-assessed disaster medical knowledge base than those who had not (p < 0.007 and p < 0.001, respectively).Most medical and nursing students in this study rated their disaster medical knowledge as insufficient. The correlation between the amount of disaster medical education and self-assessed disaster medical knowledge should influence and help direct Swedish educational policies.
