State-of-the-art global models underestimate impacts from climate extremes

Global impact models represent process-level understanding of how natural and human systems may be affected by climate change. Their projections are used in integrated assessments of climate change. Here we test, for the first time, systematically across many important systems, how well such impact models capture the impacts of extreme climate conditions. Using the 2003 European heat wave and drou

Effectiveness of green infrastructure for improvement of air quality in urban street canyons

Street-level concentrations of nitrogen dioxide (NO2) and particulate matter (PM) exceed public health standards in many cities, causing increased mortality and morbidity. Concentrations can be reduced by controlling emissions, increasing dispersion, or increasing deposition rates, but little attention has been paid to the latter as a pollution control method. Both NO2 and PM are deposited onto su

Phthalate levels in indoor dust and associations to croup in the SELMA study

Phthalates are ubiquitous indoor pollutants which have been associated with child airway disease although results are inconclusive. This study examined associations between phthalate levels in residential indoor dust and croup during infancy. Settled indoor dust was collected in 482 homes of 6-month-old infants in the Swedish Environmental Longitudinal, Mother and child, Asthma and allergy (SELMA)

Critical thinking and the humanities : A case study of conceptualizations and teaching practices at the Section for Cinema Studies at Stockholm University

The raison d’être of the humanities is widely held to reside in its unique ability to generate critical thinking and critical thinkers. But what is “critical thinking?” Is it a generalized mode of reasoning or a form of political critique? How does it relate to discipline-specific practices of scholarly pursuit? How does it relate to discourses of “post-truth” and “alternative facts”? How is it be

Nutritional status and outcome of surgery : A prospective observational cohort study of children at a tertiary surgical hospital in Harare, Zimbabwe

Background: Undernutrition contributes to nearly 50% of all child deaths in the world, yet there is conflicting evidence regarding the association between nutritional status and postoperative complications. The aim was to describe the preoperative nutritional status among pediatric surgery patients in Zimbabwe, and to assess if nutritional status was a risk factor for adverse postoperative outcome

Older person’s experiences of benefits gained from the support and advice given during preventive home visits

Background: Life expectancy is increasing all over the world. To be able to support this positive development, health interventions focusing on promotion and prevention are crucial. Preventive home visits represent one example of a health intervention which addresses both promotion through a supportive dialogue and prevention by giving advice. However, to give support and advice that older persons

Development of high intensity neutron source at the European Spallation Source

The European Spallation Source being constructed in Lund, Sweden will provide the user community with a neutron source of unprecedented brightness. By 2025, a suite of 15 instruments will be served by a high-brightness moderator system placed above the spallation target. The ESS infrastructure, consisting of the proton linac, the target station, and the instrument halls, allows for implementation

Hyponatraemia despite isotonic maintenance fluid therapy : A time series intervention study

Objective: To examine the prevalence of dysnatraemias among children admitted for paediatric surgery before and after a change from hypotonic to isotonic intravenous maintenance fluid therapy. Design: Retrospective consecutive time series intervention study. Setting: Paediatric surgery ward at the Children's Hospital in Lund, during a 7-year period, 2010-2017. Patients: All children with a blood s

Impacts of land use and land cover change in response to different driving forces in Uganda : evidence from a review

This reviewe of Land Use Land Cover Change (LULCC) studies in Uganda indicate agriculture, forest, grassland, and woodland as the major land use and land cover types. Central Uganda is the most studied region (15%), followed by western (14), eastern (10), and northern Uganda (3). District scale studies were (48%), catchment (19%), forest (17%), national (10%), and park (7%). Landsat 30 m and remot

Per oltre quarant’anni, la scrittura della storia nei paesi dell’Europa orientaleè stata fortemente condizionata dagli imperativi ideologici e propagandisticidei regimi comunisti. La storia, più di ogni altra disciplina umanistica, offrivagiustifi cazioni, e quindi legittimità, al potere. Indagare il rapporto tra storia epotere in questo ambito signifi ca tanto addentrarsi nella storia dei sociali

School Nurses’ Perceptions About Student's Wellbeing During the Covid-19 Pandemic in Sweden

The coronavirus 2019 (Covid-19) pandemic has affected both the private and public lives of people worldwide. Countries have chosen different strategies to reduce the spread of infection, including school closures and distance learning. This study aimed to describe school nurses’ perceptions about the wellbeing of students during the Covid-19 pandemic in Sweden. Interviews in five focus groups and

Latitudinal variations in δ30Si and δ15N signatures along the Peruvian shelf : Quantifying the effects of nutrient utilization versus denitrification over the past 600 years

The stable sedimentary nitrogen isotope compositions of bulk organic matter (δ15Nbulk) and the silicon isotope composition of diatoms (δ30SiBSi) both mainly reflect the degree of past nutrient utilization by primary producers. However, in ocean areas where anoxic and suboxic conditions prevail, the δ15Nbulk signal ultimately recorded within the sediments is also influenced by water column denitrif

Stable silicon isotope signatures of marine pore waters – Biogenic opal dissolution versus authigenic clay mineral formation

Dissolved silicon isotope compositions have been analysed for the first time in pore waters (δ30SiPW) of three short sediment cores from the Peruvian margin upwelling region with distinctly different biogenic opal content in order to investigate silicon isotope fractionation behaviour during early diagenetic turnover of biogenic opal in marine sediments. The δ30SiPW varies between +1.1‰ and +1.9‰

[Kr]4d104f13, The final layzer quenched configuration for highly charged ions

We discuss the Layzer quenched ground state configuration of [Kr]4d104f13 along the Praseodymium (Pr) isoelectronic sequence between 80≤Z≤100. The 2F fine structure energy is examined from the point of view of the various contirbutions: correlation, frequency-independent and dependent Breit interaction and the two QED terms, self energy and vacuum polarisation. We find the fine structure energy to

Polarizable Embedding Complex Polarization Propagator in Four- and Two-Component Frameworks

Explicit embedding methods combined with the complex polarization propagator (CPP) enable the modeling of spectroscopy for increasingly complex systems with a high density of states. We present the first derivation and implementation of the CPP in four- and exact-two-component (X2C) polarizable embedding (PE) frameworks. We denote the developed methods PE-4c-CPP and PE-X2C-CPP, respectively. We il

Self-rated health in Swedish pregnant women : a comprehensive population register study

Background/Aims Sociodemographic factors are associated with perceived overall health status or ‘self-rated health’. However, research using data from the comprehensive population register in Sweden to examine self-rated health in pregnant women is limited. This study aimed to examine sociodemographic factors associated with self-rated health before, during and after pregnancy in low-risk pregnant
