A comparison between three different types of particle sizing instruments (fast mobility particle sizer, FMPS; electrical low pressure impactor, ELPI; and scanning mobility particle sizer, SMPS) and one condensation particle counter (CPC) was made to compare instrument response in terms of size distributions and number concentration. Spherical oil droplets in 39 different sizes, with geometric mea
Bird brooches at Uppåkra have a changing biography, as grave gifts, pendants, and scrap metal. The association between bird brooches and birds of prey, and a male face to female jewellery opens questions of identy of the wearer and the male person in question. Following the bird brooches and the connotations of falconry decode both a social identiy and a lifestyle, expressed in the aestetics of th

Inducible NO-synthases (iNOS), and endothelial NO-synthases (eNOS) are two enzymes known to regulate its
Theoretical approaches to learning in practice-based jazz improvisation contexts include situated learning and ecological perspectives. This article focuses on how interest-driven, self-sustaining jazz learning activities can be matched against the concepts of stolen knowledge (Brown & Duguid, 1996) and landscape of learning (Bjerstedt, 2014). Based on an extensive interview study with Swedish
Platform ecosystems include complementary product markets that are creating unprecedented business oppor-tunities. Competition within complementary product markets is increasingly intense and fast-changing, and this leads to increased complexity in designing strategies to gain competitive advantage. Prior literature has exten-sively analyzed the key drivers of platform adoption by end users. Recen
Sensitizing capacities and cross-reactivity patterns of some diisocyanates and amines using the guinea-pig maximization test. Can p-phenylenediamine be used as a marker for diisocyanate contact allergy?
BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors
Reproducible climate reconstructions of the Common Era (1 CE to present) are key to placing industrial-era warming into the context of natural climatic variability. Here we present a community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative. The database gathers 692 records from 648 locations, including all continental regions and major ocean basins. The records
Most microalgal species are geographically widespread, but little is known about how they are dispersed. One potential mechanism for long-distance dispersal is through birds, which may transport cells internally (endozoochory) and deposit them during, or in-between, their migratory stopovers. We hypothesize that dinoflagellates, in particular resting stages, can tolerate bird digestion; that bird
A cohesive society is not only characterised by the availability of basic services and facilities, but also promotes economic equality and inclusion, democracy, and social solidarity. Forced displacement due to disasters and conflict constantly disrupt the path to a sustainable and cohesive society. Displaced communities often struggle with a lack of access to livelihood and a lack of financial in
Since the 1970s, environment and energy-related problems have moved to centre stage on many political, business and research agendas. The notion of sustainable development has emerged as the dominant global discourse to adapt societies and economies to novel modes of production and consumption in areas such as transport, energy, housing, agriculture and food. For such shifts, new technology and te
Objective To describe the incidence and burden of illness at the Tokyo 2020 Paralympic Games, which was organised with strict COVID-19 countermeasures. Methods Daily illnesses were recorded via the web-based injury and illness surveillance system (teams with their own medical staff; n=81), and local polyclinic services (teams without their own medical staff; n=81). Illness proportion, incidence an
Timely detection and surveillance of disease community spread is a potent tool for implementing effective public health interventions. This study investigates the National Telehealth Service (1177 helpline) across 18 regions in Sweden in 2020 to identify early signals of community transmission of COVID-19 at the beginning of the pandemic. Focusing on calls related to key COVID-19 symptoms (cough,
With their superficially shark-like appearance, the Mesozoic ichthyosaurs provide a classic illustration of major morphological adaptations in an ancestrally terrestrial tetrapod lineage following the invasion of marine habitats1, 2–3. Much of what is known about ichthyosaur soft tissues derives from specimens with body outlines4, 5–6. However, despite offering insights into aspects of biology tha
This study investigates the impacts of a range of interventions aimed at reducing in emissions in three high-impact sectors in cities: built environment, mobility, and sustainable energy systems. It does so by focusing on four cities around the world that are pioneering circular economy solutions (Bogotá, Glasgow, Genoa and Milan), and uses a GTAP-modelling approach developed by C40, Arup and the
The twin transition, which combines green and digital innovation in economic activities, is increasingly central to policy agendas and is also receiving growing attention in regional research. However, accurately mapping green, digital and twin (both green and digital) economic activities across regions remains challenging, particularly due to data constraints. In this study, we advance this resea
