High-Arctic environments are facing an elevated pace of warming and increasing human activities, making them more susceptible to the introduction and spread of alien species. We investigated the role of human disturbance in facilitating the spread of a native plant (Papaver dahlianum) in a high-Arctic natural environment close to Isfjord Radio station and along adjacent hiking trails at Kapp Linné
Aim: Grass-yellow butterflies (Eurema) are a group of pantropical Pieridae distributed throughout Asia, Australasia, Africa and the New World. However, little is known about their diversification, including the biogeographic mechanism(s) explaining their circumglobal distribution. We present the first densely sampled, time-calibrated phylogeny and biogeographic reconstruction of grass-yellows to c
The purpose of this essay was to examine the experience of the judicial process concerning domestic violence from the perspectives of abused females and from some of the authorities and organisations which meet these women. The essay investigated several views of the judicial process in order to obtain a wide perspective. It responded to the following questions: - How are abused women treated by
The novel method of modification of polyethersulfone (PES) ultrafiltration membranes is proposed. This method involves the use of aqueous solutions of polyacrylic acid (PAA) of different molecular weights (Mn=5.1×103 g·mol–1, Mn=490×103 g·mol–1) as a coagulant in non-solvent induced phase inversion process (NIPS). Addition of PAA (0.05–1.5 wt%) to the coagulation bath leads to marked changes in pe
Background: Organ involvement often occurs in early systemic sclerosis and has been related to premature death. Identifying patients at diagnosis at risk of developing early organ involvement would be useful to optimize screening and management strategies. Objective: To develop prediction models for the 5-year development of interstitial lung disease, pulmonary arterial hypertension and death. Met
Peat mosses (Sphagnum) are ecosystem engineers that largely govern carbon sequestration in northern hemisphere peatlands. I investigated functional traits in Sphagnum species and addressed the questions: (I) Are growth, photosynthesis and decomposition and the trade-offs between these traits related to habitat or phylogeny?, (II) Which are the determinants of decomposition and are there trade-offs
Numerous species adopt inducible defence strategies; that is, they have phenotypically plastic traits that decrease the risk of capture and consumption by potential predators. The benefits of expressing alternative phenotypes in high- vs. low-risk environments are well documented. However, inducible anti-predator traits are also expected to incur costs, as they are not expressed when predators are
AbstractModern medicine and health care rely on a variety of diagnostic and therapeutic equipment and methods that involve ionizing radiation. To guarantee quality and the safety of patients and staff, advanced radiation detectors and dosemeters are needed that have low energy and operate with directional independence for X-ray and γ-ray photons. Similar instruments are also of great importance fo

Aims: Pain and poor health-related quality of life measures serve as the primary indication for primary elective total hip arthroplasty (THA). It remains challenging to predict whether THA delivers the patient-anticipated improvements. Our study aimed to develop and validate statistical and machine learning prediction models of one-year clinical improvement in patient-reported outcome measures (PR
We present the detection and characterisation of the TOI-1438 multi-planet system discovered by the Transiting Exoplanet Survey Satellite (TESS). To confirm the planetary nature of the candidates and determine their masses, we collected a series of followup observations including high-spectral resolution observations with HARPS-N and HIRES over a period of 5 years. Our combined modelling shows tha
Diffusion kurtosis imaging (DKI) allows for assessment of diffusion influenced by microcellular structures. We analyzed DKI in suspected low-grade gliomas prior to histopathological diagnosis. The aim was to investigate if diffusion parameters in the perilesional normal-appearing white matter (NAWM) differed from contralesional white matter, and to investigate differences between glioma malignancy
Intensive agricultural management negatively affects both natural enemies of pests and pollinators. Such management also has the potential to adversely affect the ecosystem services that these communities confer. Organic management has been proposed as an alternative method to mitigate such problems by restoring the services provided by arthropod communities. We evaluated the effect of organic man
This thesis addresses the challenge of transforming car-oriented, mono-functional big-box landscapes into multi-functional, walkable local-centre. It assembles an integrated framework from recent research and translates it into a design approach to be tried in a case study. In contrast to the proposed multi-functional approach, a monocentric urban system concentrates functions and advantages in
Context. Hot Jupiters (HJs) with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories, which lead to the possible ejection of other planets. TOI-2109 b is special in this regard because it is the HJ with the closest relative separation from its host star, being separated by less than 2.3 stellar
Forests are vital ecosystems that support biodiversity, regulate climate, and provide economic and social value. Their resilience is strongly influenced by harvesting methods, with selective cutting and rotation forestry having noticeably different impacts on carbon dynamics. Understanding these effects requires accurate data on the number and location of felled trees. Although modern harvesters c
Introduction: Amyloid- and tau-positron emission tomography (PET) are promising modalities for detecting pathological changes associated with Alzheimer’s disease (AD); however, their application is limited. Although the use of cerebrospinal fluid (CSF) biomarkers as alternatives to amyloid-PET and tau-PET has been explored, no in vitro diagnostic-approved or commercial CSF biomarker assays are cur
Background The optimal strategy for initial treatment of acute occlusion of superior mesenteric artery (SMA) is debated. The aim of the study was to compare the effectiveness, timelines and outcomes of endovascular versus open surgical treatment in patients with acute SMA occlusion. This was a preplanned substudy of the prospective observational multicenter AMESI (Acute MESenteric Ischaemia) study
