An outbreak of acidity and sulphate salts was observed on the hull of the 17th-century Swedish warship Vasa, following humidity variations in the Vasa Museum during the rainy summer in 2000. Analyses of total sulphur in oak cores sampled from 16 locations showed, in the outermost 2 cm., mean concentrations betwen 0.2 and 6 mass percent. Synchrotron-based sulphur K-edge X-ray absorption spectroscop
After the early biomineralisation event in the early Paleozoic (Cambrian –Ordovician; 541 – 443.8 Ma), the Late Triassic (237 – 201.3 Ma) represents another key period of biomineralisation with the onset of the Mesozoic plankton radiation. In the Carnian (237 – 227 Ma), the first calcifying dinoflagellates are recorded followed by the nannoliths in the middle Norian (Alaunian) and the coccolithoph
A compact reduced mechanism covering a wide range of conditions is developed for use in simulations of NH3/n-heptane combustion in engines. Reduction targets were selected after reviewing available experimental studies of NH3 combustion in engines. Ignition, flames and oxidation of NH3/n-heptane mixtures were targeted. Particularly, mixtures with very low molar percentage of n-heptane which are im
Revisiting the citizenship regimes of Myanmar and India through a comparative lens, this article argues that a specter of the “potential foreigner” is decisive in the adjudication of citizenship in both countries. Citizenship is conceptualized not only on the basis of who is a citizen, but a perennial suspicion towards those who may not be. We frame this argument in the context of increasingly res
Radical right populist parties have often been treated as “pariahs,” being excluded from coalition politics in parliamentary democracies. We argue that negative rhetoric targeted at radical right populist parties in legislative debates is used by the established parties to distance themselves from such parties and that the incentives to do so depend on the political context. Using sentiment analys
A large number of children with cleft lip and palate (CLP) were adopted to Sweden in the last decade, mainly from China. Most of the children arrived with unoperated palates and at later ages than earlier years. This article aims to present an overview of ethical challenges within the practice of international adoption of children with CLP from the perspective of plastic surgery in a welfare healt
Objective: To evaluate the long-term performance of the patch materials we have used to augment the pulmonary arterial tree across a wide spectrum of diagnoses and anatomical locations. Methods: Retrospective, single-center review of 217 consecutive pediatric patients at a tertiary referral center from 1993 to 2020 who underwent patch arterioplasty of the pulmonary arterial tree from the pulmonary

Since the Russian invasion of Ukraine in 2014, the EU and NATO have strengthened resilience, preparedness, and critical infrastructure policies in response to evolving transboundary threats. However, cascading climate risks, defined as cross-border and cross-sectoral impacts intensified by climate change, have the potential to be insufficiently understood and integrated into EU and NATO frameworks
Our way of handling the climate crisis is not fast or ambitious enough. We have the opportunity to plan for a better future, not just accept the consequences of our failure. To plan for a better future, we first need to conceptualise a vision of a desired end-point, in this case a climate-neutral and sustainable city. This essay is meant to inspire radical change by using and expanding the radical
Access to digital infrastructure in highly digitalized societies is shaped not only by the availability of technology but also by the administrative arrangements that govern access to it. This study examines how non-EU international students at Lund University experience and navigate exclusion from Sweden’s digital financial infrastructure through the case of Swish, a mobile payment system widely
Technical drawings play an important role in many industrial processes, including product development, manufacturing, and lifecycle management, by representing the product definition. The purpose of the study was to investigate which processes influence technical drawing creation and management, what challenges are associated with these processes, and how these challenges can be addressed through
This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym
In this episode, we speak to Professor John Paterson, University of Aberdeen School of Law, and partner to our Advance LLM in Energy Law of the North Sea Energy Law Partnership about Energy Law in the context of the evolving climate change, energy security and equity imperatives.
OBJECTIVE: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are chronic, relapsing inflammatory diseases, yet reliable biomarkers for detecting relapse and organ involvement remain limited. This study aimed to identify plasma protein biomarkers that distinguish active disease from remission and to explore markers associated with lung and kidney involvement.METHODS: Plasma
