According to Gloger's rule, animal colouration is expected to be darker in wetter and warmer climates. Such environmental clines are predicted to occur in colour polymorphic species and to be shaped by selection if colour morphs represent adaptations to different environments. We studied if the distribution of the colour polymorphic tawny owl (Strix aluco) morphs (a pheomelanic brown and a pale gr

We present a sub-picosecond resolved investigation of the structural solvent reorganization and geminate recombination dynamics following 400 nm two-photon excitation and photodetachment of a valence p electron from the aqueous atomic solute, I-(aq). The measurements utilized time-resolved X-ray Absorption Near Edge Structure (TR-XANES) spectroscopy and X-ray Solution Scattering (TR-XSS) at the Li

Enabling techniques for separating target cells, such as subgroups of white blood cells and cancercells from blood and other body fluids, are necessary for lab work facilitation, inline integration withhigh-end bioanalytical instrumentation, and for point-of-care or home testing. The work of this thesisaddresses this need by further studying an equilibrium-based ultrasonic wave-based technology ca

Background: It is thought that patients with inborn errors of immunity (IEI) are more susceptible to severe coronavirus disease 2019 (COVID-19) than the general population, but a quantification of this potential risk is largely missing. Objective: We assessed the impact of COVID-19 on patients with IEI. Methods: A nationwide cohort study was performed to estimate the relative risk (RR) for hospita

Background: High gluten and low dietary fiber in pregnancy intake is associated with an increased risk of celiac disease (CeD) in the child. Early life higher dietary quality is suggested to reduce the subsequent risk of CeD. Objectives: The aim was to investigate associations of pregnancy dietary quality and diversity with child risk of CeD. Methods: In The Norwegian Mother, Father and Child Coho

Background: There is no consensus or clinical guidelines for screening routines of autoimmune disease in individuals with juvenile idiopathic arthritis (JIA), since results are conflicting whether the risk for such conditions is increased or not among individuals with JIA. The aim of this study was to investigate if the frequency of comorbid autoimmune conditions is increased after JIA diagnosis i

Introduction Despite the improvements in diabetes management by continuous glucose monitoring (CGM) it is difficult to capture the complexity of CGM data in one metric. We aimed to develop a clinically relevant multidimensional scoring model with the capacity to identify the most alarming CGM episodes and/or patients from a large cohort. Research design and methods Retrospective CGM data from 2017

We present an operando study where Ambient-Pressure X-ray Photoelectron Spectroscopy (AP-XPS), Polarization Modulation-InfraRed Reflection Absorption Spectroscopy (PM-IRRAS) and Mass Spectrometry (MS) were employed simultaneously with sub-minute time resolution to monitor the CO oxidation and NO reduction reactions on Rh(111). AP-XPS is a powerful tool to follow reactions at the surface-gas interf

Popular Abstract in Swedish Modellering och krav för automation av gradningsprocessAn increasing number of robots have been used for the finishing of castings during recent years. This is mainly due to developments to overcome problems that restricted their use during the past decade. The major difficulties have been the need to control reaction forces during metal removing by grinding operations and the lack of tools designed specially for robots. The elimination of these two p

This study focuses on one of the critical design parameters of lean premixed (LPM) combustors-the air split ratio (ASR) between the pilot and main stages. The effect of the air split ratio on thermoacoustic instability is experimentally studied based on a centrally staged model combustor. It is found that the thermoacoustic instability is suppressed with the ASR higher than 20%. The acoustic modes

Background and purpose - Intramedullary nails (IMN) have become increasingly common as treatment for trochanteric hip fractures (THF) although they are costlier, and without proven superiority compared with sliding hip screws (SHS). We investigated whether the 2 methods differ in terms of short-term mortality when used in fractures where both methods are suitable. Patients and methods - We extract

The CHaracterising ExOPlanet Satellite (CHEOPS) is a partnership between the European Space Agency and Switzerland with important contributions by 10 additional ESA member States. It is the first S-class mission in the ESA Science Programme. CHEOPS has been flying on a Sun-synchronous low Earth orbit since December 2019, collecting millions of short-exposure images in the visible domain to study e

Background:Rectal cancer patients commonly benefit from neoadjuvant therapy before resection surgery. For these patients, an elective ostomy diversion is frequently considered, despite the absence of conclusive evidence when a diversion is advantageous. This is a retrospective observational single-center study on a 4-year consecutive rectal cancer cohort undergoing neoadjuvant therapy, aiming at i

Cold region ecosystems store vast amounts of soil organic carbon (C), which upon warming and decomposition can affect the C balance and potentially change these ecosystems from C sinks to carbon dioxide (CO2) sources. We quantified the decadal year-round CO2 flux from an alpine steppe-ecosystem on the Tibetan Plateau using eddy covariance and automatic chamber approaches during a period of signifi

Mosses have often been used for biomonitoring because of their diversity of habitats, structural simplicity, and rapid multiplication rate. This research aimed to study the tolerance of heavy metal in 3 species of terricolous mosses i.e., Barbula consanguinea, Hyophila apiculata, and H. involuta. The gametophores of mosses were immersed at 4 concentrations of each of the heavy metals Cd, Pb, and Z

While the eddy covariance (EC) technique is a well-established method for measuring water fluxes (i.e., evaporation or 'evapotranspiration’, ET), the measurement is susceptible to many uncertainties. One such issue is the potential underestimation of ET when relative humidity (RH) is high (>70%), due to low-pass filtering with some EC systems. Yet, this underestimation for different types of EC sy

Background: Artificial intelligence (AI) systems are proposed as a replacement of the first reader in double reading within mammography screening. We aimed to assess cancer detection accuracy of an AI system in a Danish screening population. Methods: We retrieved a consecutive screening cohort from the Region of Southern Denmark including all participating women between Aug 4, 2014, and August 15,

The onset of Earth's present icehouse climate in the Late Eocene coincides with astronomical events of enigmatic causation. At similar to 36 Ma ago the 90-100 km large Popigai and Chesapeake Bay impact structures formed within similar to 10-20 ka. Enrichments of He-3 in coeval sediments also indicate high fluxes of interplanetary dust to Earth for 2 Ma. Additionally, several medium-sized impact st

The Arctic land area has warmed by > 1 A degrees C in the last 30 years and there is evidence that this has led to increased productivity and stature of tundra vegetation and reduced albedo, effecting a positive (amplifying) feedback to climate warming. We applied an individual-based dynamic vegetation model over the Arctic forced by observed climate and atmospheric CO2 for 1980-2006. Averaged ove
