Background: Migratory birds play an important part in the spread of parasites, with more or less impact on resident birds. Previous studies focus on the prevalence of parasites, but changes in infection intensity over time have rarely been studied. As infection intensity can be quantified by qPCR, we measured infection intensity during different seasons, which is important for our understanding of

Large gulls are generalist predators that play an important role in Arctic food webs. Describing the migratory patterns and phenology of these predators is essential to understanding how Arctic ecosystems function. However, from all six large Arctic gull taxa, including three long-distance migrants, to date seasonal movements have been studied only in three and with small sample sizes. To document

Preconception health status, especially of women, but also of men, is known to influence pregnancy outcomes. Despite knowledge of the growing importance of preconception health, numerous challenges remain for conducting research in this population and delivering appropriate clinical care. The 2023 Global Pregnancy Collaboration annual workshop focused on exploring preconception health as it relate

Objective: To investigate the dynamic changes of soluble fms-like tyrosine kinase−1 (sFlt−1), placental growth factor (PlGF) and their ratio in maternal plasma, from preeclampsia diagnosis to postpartum, evaluating its clinical utility. Methods: Single-center prospective longitudinal cohort study with repeated sample collection in women with established preeclampsia (PE). Seventy-five (n = 75) wom

Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. The main aim of this thesis is to understand the effe

Popular Abstract in English Fish are an excellent source of healthy protein and fat in the human nutrition. However, the fisheries cannot supply enough of fish to satisfy the demand of a growing world’s population. Sustainable aquaculture can help feeding the growing world. This business is growing every year, and together with it the fish farms and fish feed factories are growing. This created thAs aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. The Holmen pellet tester (NHP 100) could be adapted for this purpose, but the spec

Coiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. The best studied examples of the latter are crescentin in Caulobacter crescentus that determines the curved cell shape, and FilP (filament forming-p

Most of field stars originate from dissolved star clusters. If the gas cloud is well mixed the stars in the cluster are expected to be chemically homogenous. Although the original kinematical information of a star may be lost under the Galactic dynamic evolution, the chemical signatures are preserved in the form of elemental abundances in individual low-mass stars. The present-day distribution of

Recently the Intergovernmental Panel on Climate Change released their 6th Assessment reports which confirm that the impact of climate change is visible, e.g. through an increased weather volatility leading both to hotter drier weather and increased flooding in some regions globally. One clear example of this is the increased prevalence of wildfires in recent years and increasing wildfire potentialRecently the Intergovernmental Panel on Climate Change released their 6th Assessment reports which confirm that the impact of climate change is visible, e.g. through an increased weather volatility leading both to hotter drier weather and increased flooding in some regions globally.

Urban Living Labs (ULLs) are widely promoted as experimental spaces for urban innovation, particularly in EU policy contexts. Yet their design is often shaped by current institutional logics, EU-funding structures, and sector-specific constraints, especially in transport, a domain marked by technical path dependencies and dominant narratives of efficiency and optimization. These conditions risk na

Popular Abstract in Swedish Denna avhandling fokuserar på två av de många faktorer som är av fundamental betydelse både för människors välfärd och för ett lands utveckling dvs. val av dricksvattenkälla och toalettfacilitet. I avhandlingen analyseras olika aspekter av hushållsefterfrågan på dessa två faktorer med hjälp av data från Filippinerna och Bangladesh. Avhandlingen består av fem kapitel, etThis thesis focuses on different aspects of household demand, and the determinants of demand, for water and sanitation related inputs fundamental to the households' well-being, i.e. drinking water and toilet facilities. The thesis consists of five chapters, one introductory chapter and four self-contained, essentially empirical, studies. In chapter two, Women's Health Choices and the Effects on C

Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of

Popular Abstract in Swedish Osteoartros (populärt kallat utsliten led) är ett vanligt tillstånd i höft- och knäled. Smärta, stelhet och minskade möjligheter att röra sig fritt är vanliga symtom. Att byta ut leden helt vid en operation är ett effektivt sätt att lindra patienternas besvär. Dessa operationer är vanliga i hela västvärlden och prognoser tyder på en tilltagande tendens i det årliga antaBackground: Elective knee and hip arthroplasty are common surgical procedures. Improved anaesthetic and nutritional care has the potential of increasing patient satisfaction and reducing length of hospital stay (LOS). The overall aim of this thesis was to evaluate the effect of perioperative nutrition and different anaesthetic techniques on per- and postoperative outcome after elective total hip (

Global environmental issues concern a growing number of people and businesses are expected to communicate efforts towards environmental sustainability. Due to the controversial nature of its business practices and contribution to environmental problems, the oil industry holds a poor reputation and is considered to have a special need to communicate their efforts towards more sustainable business p
