Electric propulsion using C.sub.60 molecules

Fullerene propellants, which are stable carbon cage structures composed of even numbers of carbon atoms in the range of about 32 to 200 atoms, particularly a combination of conveniently obtainable C.sub.60 and C.sub.70, may be carried in solid form in a spacecraft, sublimated to produce the appropriate molecular propellant such as C.sub.60 or C.sub.70, which may then be ionized by DC discharge or RF radiation to efficiently produce specific impulses in the range above 1000 lbf -s/lbm

Clustering of children's activity behaviour: the use of self-report versus direct measures

While we concur with the objectives of the recent International Journal of Behavioural Nutrition and Physical Activity paper published by Jago and colleagues titled "Physical activity and sedentary behaviour typologies of 10-11 year olds", we feel that the results as currently presented do not support their conclusions. Though the authors created groups of children with dramatically different patterns of self-reported physical activity and sedentary behaviour, an inspection of the objectively measured accelerometry data shows little difference between the groups. Further, in at least one instance the difference between groups was of the opposite direction when using objective measures, as opposed to the self-report measures used in the published analysis. Thus, we caution the authors from making conclusions based on their self-report data, and propose that they re-analyze their data using their objectively measured data instead

Collaboration Makes More Lights Come on than Those on the Runway: Experiential Learning through an Interdisciplinary Fashion Show Project Merges Fashion and Technology

Inspired by the Metropolitan Museum of Art exhibit, Manus x Machina: Fashion in an Age of Technology, the idea for the theme Futuristic Floral was born to guide the direction of the Apparel Merchandising and Product Development (AMPD) fashion show. In only the second year of production, we wanted to make sure the show would entertain the audience and be a professional production. However, as educators, our primary goal was to make a lasting impact on the education of our students. This project has pushed our students to think, act, communicate, and create on a level that would not have been possible without the interaction of students from apparel and electrical engineering. The true impact for all students involved remains to be seen when the lights go down after the show and they realize they have been a part of something much bigger than they could create on their own

Le retour au travail dans un contexte de barrières linguistiques : Une étude comparative des politiques et des pratiques d’indemnisation des victimes de lésion professionnelle au Québec et en Ontario

La façon dont les régimes d’indemnisation des victimes de lésion professionnelle doivent tenir compte des barrières linguistiques est d’une importance capitale à la lumière de la diversification linguistique croissante du Canada. S’appuyant sur des entrevues menées auprès de travailleurs accidentés et d’informateurs clés, cette étude est la première à examiner, de manière empirique, les politiques et les pratiques du retour au travail sous l’angle des barrières linguistiques. En comparant les juridictions du Québec et de l’Ontario, l’étude met en lumière des similitudes et des différences touchant les accommodements linguistiques ainsi que les politiques et les pratiques du retour au travail qui déterminent les expériences des travailleurs accidentés ayant des besoins linguistiques. Elle fait valoir que les lacunes à cet égard, qui sont plus marquées au Québec, contribuent à un faible retour au travail pour ces travailleurs dans les deux provinces.The question of how workers’ compensation systems should account for language barriers is of increasing importance given Canada’s growing linguistic diversity. This study is the first to empirically examine, based on interviews with injured workers and key informants, return-to-work policies and practices through the lens of language barriers. By comparing two jurisdictions, Quebec and Ontario, the study highlights similarities and differences in language accommodation and return-to-work policies and practices that shape the experiences of injured workers with language needs. It argues that gaps in this regard, which are more pronounced in Quebec, contribute to poor return-to-work outcomes for these workers in both provinces

High-resolution mapping of losses and gains of Earth’s tidal wetlands

Tidal wetlands are expected to respond dynamically to global environmental change, but the extent to which wetland losses have been offset by gains remains poorly understood. We developed a global analysis of satellite data to simultaneously monitor change in three highly interconnected intertidal ecosystem types—tidal flats, tidal marshes, and mangroves—from 1999 to 2019. Globally, 13,700 square kilometers of tidal wetlands have been lost, but these have been substantially offset by gains of 9700 km2, leading to a net change of −4000 km2 over two decades. We found that 27% of these losses and gains were associated with direct human activities such as conversion to agriculture and restoration of lost wetlands. All other changes were attributed to indirect drivers, including the effects of coastal processes and climate change

Examining the Course of Transitions from Hospital to Home-based Palliative Care: A Mixed Methods Study

Background: Hospital-to-home transitions in palliative care are fraught with challenges. To assess transitions researchers have used patient reported outcome measures and qualitative data to give unique insights into a phenomenon. Few measures examine care setting transitions in palliative care, yet domains identified in other populations are likely relevant for patients receiving palliative care. Aim: Gain insight into how patients experience three domains, discharge readiness, transition quality, and discharge-coping, during hospital-to-home transitions. Design: Longitudinal, convergent parallel mixed methods study design with two data collection visits: in-hospital before and 3–4 weeks after discharge. Participants completed scales assessing discharge readiness, transition quality, and post discharge-coping. A qualitative interview was conducted at both visits. Data were analyzed separately and integrated using a merged transformative methodology, allowing us to compare and contrast the data. Setting and participants: Study was set in two tertiary hospitals in Toronto, Canada. Adult inpatients (n = 25) and their caregivers (n = 14) were eligible if they received a palliative care consultation and transitioned to home-based palliative care. Results: Results were organized aligning with the scales; finding low discharge readiness (5.8; IQR: 1.9), moderate transition quality (66.7; IQR: 33.33), and poor discharge-coping (5.0; IQR: 2.6), respectively. Positive transitions involved feeling well supported, managing medications, feeling well, and having healthcare needs met. Challenges in transitions were feeling unwell, confusion over medications, unclear healthcare responsibilities, and emotional distress. Conclusions: We identified aspects of these three domains that may be targeted to improve transitions through intervention development. Identified discrepancies between the data types should be considered for future research exploration
