BACKGROUND: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.METHODS: This was an international, prospective, multicentre,
Arctic clouds are sensitive to atmospheric particles since these are sometimes in such low concentrations that clouds cannot always form under supersaturated water vapor conditions. This is especially true in the late summer, when aerosol concentrations are generally very low in the high Arctic. The environment changes rapidly around freeze-up as the open waters close and snow starts accumulating
Road traffic pollution is one of the most important factors among other environmental factors that influence the roadside vegetation. The present research examines the impact of motorway flyovers and at-grade roads on air pollution (PM10, SOx, NOx, and air quality index (AQI)) and roadside vegetation in Dehradun by considering the important biochemical parameters such as chlorophyll, ascorbic acid
In 1620, the Danish colony of Tranquebar, on the Coromandel Coast in India, was founded by an expedition jointly mounted by the Danish Crown and the Danish East India Company, under the command of the Danish nobleman Ove Gjedde. Gjedde soon went back to Denmark, but the experiences gained in the colony proved important for his future career as a military man, civil servant and industrialist. The p
This study provides an in-depth analysis of the impact of a multimodal journey-planning app on users of informal public transport systems in Cochabamba, Bolivia. We analyze survey data (N=648) collected through the Trufi Association NGO's digital travel app on changes in mobility behavior, satisfaction, and everyday life improvements. Participants report more frequent use of informal transport (49
Projecting El Niño-Southern Oscillation responses to future climate change are hindered by limited paleoclimate records spanning past abrupt climate transitions. This study combines multi-proxy records from the Northwest Borneo Trough over the past 30 kyr with transient climate simulations, reconstructing tropical western Pacific hydroclimate during Heinrich events and Bølling–Allerød warming. Res
Highly oxygenated organic molecules (HOM) play a crucial role in the formation and growth of atmospheric particles, thereby influencing air quality and climate. A comprehensive understanding of HOM formation, particularly an accurate quantification of their yields, is essential to constrain the climate and health impacts of aerosols. Previous studies often reported constant HOM yields as averages,
Migration has a global impact, but it also intersects with local and nationalissues. In 2020, 281 million people lived outside their country of birth or citizenship, according to the United Nations Global Migration Database. The number of persons displaced across international borders is increasing due to conflict, persecution, and violence. Most of the world’s refugees and asylum seekers live i
This research focuses on the extreme case of when the Chinese city of Wuhan was locked down during the COVID-19 pandemic in early 2020. Combining media study with a spatial perspective, it aims to reveal how the Wuhanese diaspora use and engage with the media to relate back to Wuhan while they are geographically absent. This study reflects on how they form a sense of place towards both their home
Vegetationsbränder är världsomspännande problem som skakar samhällen genom att skada deras ekonomier och orsaka allvarliga, ibland dödliga, hälsokomplikationer bland deras befolkningar. Takten av vegetationsbrandsförekomst har ökat de senaste åren till följd av en stigande global medeltemperatur. Denna takt förväntas att fortsätta öka på grund av den globala uppvärmningen. I efterdyningarna av braWildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. In Sweden, in the aftermath of the 2014 Västmanla
Despite longstanding and far-reaching recognition of the need for social change towards environmental sustainability, the delivery of this transition is proving problematic. Dominant strategies for sustainable development in western countries focus on uncoupling economic development from ecological harm. Scandinavia epitomises this approach to green economy, especially in the transition to a low-c

Mesozoikum anses ha utgjort en ”växthusperiod” i Jordens historia med avsevärt höga koldiox-idhalter i atmosfären samt förhöjda temperaturer, men det återstår många frågor att besvara angående klimatut-vecklingen för hela detta intervall. Tidig jura karaktäriseras till exempel av ett varmt klimat, och föregås och efter-följs av två kortare perioder med väldigt höga CO2 halter, som sammanfaller medThe Mesozoic was a so-called “hothouse” time period in Earth’s history, with high concentrations of atmospheric CO2 and elevated temperatures, but the exact climate evolution is not fully known for the entire inter-val. The Early Jurassic for instance is believed to have been a warm period, flanked by two episodes of extremely high CO2, coinciding with environmental degradation and mass extinction
Soil microbial properties were studied from localities on a transect along the Yenisei River, Central Siberia. The 1000 km-long transect, from 56°N to 68°N, passed through tundra, taiga and pine forest characteristic of Northern Russia. Soil microbial properties were characterized by dehydrogenase activity, microbial biomass, composition of microbial community (PLFAs), respiration rates, denitrifi
This paper compares two flow routing algorithms' influences on ecohydrological estimations in a northern peatland catchment, within the framework of an arctic-enabled version of the dynamic ecosystem model LPJ-GUESS. Accurate hydrological estimations are needed to fully capture vegetation dynamics and carbon fluxes in the subarctic peatland enviroment. A previously proposed distributed hydrologica
Croplands are vital ecosystems for human well-being and provide important ecosystem services such as crop yields, retention of nitrogen and carbon storage. On large (regional to global)-scale levels, assessment of how these different services will vary in space and time, especially in response to cropland management, are scarce. We explore cropland management alternatives and the effect these can
