Plast är ett av våra vanligaste material i vardagen. Som helhet är det ett billigt, slitstarkt och lätt material. Det finns olika typer av plast med olika egenskaper. Gemensamt för alla plaster är dock att de består av (oftast en typ av) molekyler som sitter ihop i långa, repeterande kedjor. Dessa kedjor kallas polymerer. När plast slängs i naturen eller hanteras fel som avfall finns det en risk aAs plastic pollution in aquatic environments persists, gaining a deeper understanding of nanoparticles has become increasingly important. Yet, the question remains: what happens to plastic as it breaks down into smaller components, and ultimately, what end products are formed? Current plastic degradation methods are limited in their environmental applicability and efficiency. This study aims to pr

This essay demonstrates that the origin of modern Russian national conservatism lies in the Soviet underground anti-communist and anti-liberal movement, which developed under the strong influence of the theorists of integral traditionalism, fascism, and the Nouvelle Droite. Vladimir Putin's political ontology, based on the idea of the tragedy of Russia and Europe caused by the weakening of their s

Feel overwhelmed but realise the need to understand what's going on? Academic analytical frameworks can help.European countries, and Denmark in particular, are scrambling to respond to threats from US officials over the future of Greenland.Having successfully taken out the leadership of Venezuela in a raid on January 3, an emboldened US government is talking about simply taking Greenland for itsel

Elektroniska hälsodata produceras, insamlas och används idag av ett stort antal olika typer av aktörer inom EU. Tillgången till och delningen av denna elektroniska hälsodata anses utgöra ett led i att såväl förbättra hälso- och sjukvården inom unionen som för främjandet av exempelvis innovation och forskning. För att kunna förverkliga den fulla potential denna elektroniska hälsodata innehar inrättElectronic health data are currently produced, collected and used by a wide range of actors within the European Union. Access to and sharing of such data are regarded as instrumental in both improving healthcare within the Union and in promoting, inter alia, innovation and research. In early 2025, through the European Health Data Space Regulation, a framework governing the use and exchange of such

BACKGROUND: Brain function emerges from structural pathways enabling neural connectivity and communication. However, the extent of structural-functional coupling varies across brain regions, and its alteration in aging and early Alzheimer's disease (AD) remains unclear. This study investigated variations in coupling associated with age, sex, and amyloid burden in a cohort of older adults without d

The customer order decoupling point (CODP) is the point in the supply chain where the product is linked to a customer order and is, by definition, the last stock point along the supply chain. The CODP decouples the upstream operations that are made to stock from the downstream operations that are triggered by customer orders. We employed a systematic literature review of the empirical research on

Despite tremendous progress seen in the computational fluid dynamics community for the past few decades, numerical tools are still too slow for the simulation of practical flow problems, consuming thousands or even millions of computational core-hours. To enable feasible multi-disciplinary analysis and design, the numerical techniques need to be accelerated by orders of magnitude. Reduced-order mo

The 5th generation of mobile networks introduces a new Network Function (NF) that was not present in previous generations, namely the Network Data Analytics Function (NWDAF). Its primary objective is to provide advanced analytics services to various entities within the network and also towards external application services in the 5G ecosystem. One of the key use cases of NWDAF is mobility trajecto

Positive teacher-student and student-student relationships are among the most significant factors contributing to learning, motivation, wellbeing, and graduation rates in higher education. Trust is commonly understood as a key element for the development and sustenance of positive educational relationships, yet relatively little empirical research investigates trust in higher education classrooms.

Mutations in the NRF2-KEAP1 pathway are common in non-small cell lung cancer (NSCLC) and confer broad-spectrum therapeutic resistance, leading to poor outcomes. The cystine/glutamate antiporter, system xc-, is one of the >200 cytoprotective proteins controlled by NRF2, which can be non-invasively imaged by (S)-4-(3-18F-fluoropropyl)-l-glutamate ([18F]FSPG) positron emission tomography (PET). Throu

The tunneling dynamics of a magnetic Dy164 quantum gas in an elongated or pancake skewed double-well trap is investigated with a time-dependent extended Gross-Pitaevskii approach. Upon lifting the energy offset, different tunneling regimes can be identified. In the elongated trap and for sufficiently large offset, the different configurations exhibit collective macroscopic tunneling. For smaller o

The effective material response as observed at a macro level is a manifestation of the material microstructure and lower scale processes. Due to their distinct atomic arrangement, compared to bulk material, grain boundaries significantly affect the electrical properties of metals. However, a scale-bridging understanding of the associated microstructure–property relation remains elusive so that phe

Purpose: Tricuspid valve flow velocities are challenging to measure with cardiovascular MR, as the rapidly moving valvular plane prohibits direct flow evaluation, but they are vitally important to diastolic function evaluation. We developed an automated valve-tracking 2D method for measuring flow through the dynamic tricuspid valve. Methods: Nine healthy subjects and 2 patients were imaged. The ap

Diplomatihistorien hör till en av historievetenskapens giganter som under sin livsbana ofta ifrågasatts och utmanats. Denna artikel inleds med en historiografisk tillbakablick på framväxten av New Diplomatic History, dess definitioner av tidigmodern diplomati, samt en överblick av aktuella forskningsteman och frågor i internationell forskning. Särskilt fokus läggs på nordisk diplomatihistoria via Diplomatic history is one of the giants of historical scholarship, which has often been questioned and challenged throughout its lifetime. This article discusses the field of New Diplomatic History centered on definitions of diplomacy in general and specifically on research on the early modern period during the last decades. Special focus is placed on Nordic early modern diplomatic history through

BACKGROUND: Moderate differences in efficacy between adjuvant chemotherapy regimens for breast cancer are plausible, and could affect treatment choices. We sought any such differences.METHODS: We undertook individual-patient-data meta-analyses of the randomised trials comparing: any taxane-plus-anthracycline-based regimen versus the same, or more, non-taxane chemotherapy (n=44,000); one anthracycl

OBJECTIVE: The purpose of this study was to identify a panel of biomarkers for distinguishing early stage sepsis patients from non-infected trauma patients.BACKGROUND: Accurate differentiation between trauma-induced sterile inflammation and real infective sepsis poses a complex life-threatening medical challenge because of their common symptoms albeit diverging clinical implications, namely differ

Background: People with intellectual disability (ID) were identified by the Public Health Agency of Sweden as a risk group for Covid-19. At the same time, they have been found to experience barriers to health care, and the invasive testing for Covid-19 may be particularly frightening for people with limited cognitive understanding.Methods: Register data on diagnoses in primary, specialist and hosp
