Denna avhandling undersöker styrningen av koldioxidavskiljning och -lagring (CCS) i den nuvarande fasen av policydriven implementering inom europeisk klimatpolitik. Min forskning placeras i mellan etablerad kritik av CCS och dess framväxande, centrala roll i bindande nettonollstrategier. Jag intar en kritiskt pragmatisk hållning som erkänner att CCS är en omtvistad teknik som innebär risker för inThis thesis examines the governance of Carbon Capture and Storage (CCS) technology in its current phase of policy-driven deployment within European climate policy. Positioned in the gap between established critique of CCS and its newly central role in binding net-zero strategies, my research adopts a critical-pragmatic stance to acknowledge that CCS is a contentious technology embodying risks of c

Almost 200 years after their inception, news beats became a dominant factor that shapes newsrooms. This study explores the beat mix of leading quality dailies in 13 countries. Findings are based on executive interviews triangulated with other data sources. They indicate a shift from geographic to thematic division of labour and the rising trend of beat sub-specialisation. Newsroom size matters but

This Letter presents measurements of long-range transverse-momentum correlations using a new observable, v0(pT), serving as a probe of event-by-event radial-flow fluctuations, the underlying radial expansion, and the medium's properties in heavy-ion collisions. Results are reported for inclusive charged particles, pions, kaons, and protons across various centrality intervals in Pb-Pb collisions at

Electrospinning is a versatile technique for manufacturing micro-nano diameter fibers and has been used extensively for tissue engineering in vivo and advanced cell culture in vitro. Standard means of seeding cells onto such substrates typically offer no control over cell distribution, yielding dispersed, heterogeneous and low concentrations of cells. In this article, we investigate the viability

Background: Severe COVID-19 frequently involves multi-organ dysfunction, including acute kidney injury (AKI), which affects up to 85% of critically ill patients. While both direct viral infection and systemic effects are implicated, the role of renal microthrombosis remains poorly defined in COVID-19 and AKI. Angiopoietin-2, a pro-inflammatory cytokine, and cleaved thrombomodulin is elevated in pl

High-energy hadronic collisions generate environments characterized by temperatures above 100 MeV (refs. 1,2), about 100,000 times hotter than the centre of the Sun. At present, it is therefore unclear how light (anti)nuclei with mass number A of a few units, such as the deuteron, 3He or 4He, each bound by only a few MeV, can emerge from these collisions3,4. Here, the ALICE Collaboration reports t

Ultrarelativistic heavy-ion collisions produce a state of hot and dense strongly interacting QCD matter called quark-gluon plasma (QGP). On an event-by-event basis, the volume of the QGP in ultracentral collisions is mostly constant, while its total entropy can vary significantly due to quantum fluctuations, leading to variations in the temperature of the system. Exploiting this unique feature of

The intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. In particular, it allows for the investigations of excited, light-flavour vector mesons. The measurement of coherently photoproduced π+π−π+π− final states in ultraperipheral Pb–Pb collisions at sNN=5.02 TeV is presented for the first time. The cross section, d

Correlations among conserved quantum numbers, such as the net-electric charge, the net-baryon, and the net-strangeness in heavy-ion collisions, are crucial for exploring the QCD phase diagram. In this paper, these correlations are investigated using net-proton number (as a proxy for the net-baryon), net-kaon number (for the net-strangeness), and net-charged particle number in Pb-Pb collisions at =

Interfaces between magnetic and non-magnetic materials play a crucial role in various magnetic heterostructures. The emergence of 2D van der Waals (vdW) magnets has introduced new opportunities for exploring proximity effects in vdW heterostructures. While the influence of magnetic layers on nearby non-magnetic materials has been widely studied, it remains unclear whether non-magnetic substrates c

Heavy-flavor quarks produced in proton-proton (pp) collisions provide a unique opportunity to investigate the evolution of quark-initiated parton showers from initial hard scatterings to final-state hadrons. By examining jets that contain heavy-flavor hadrons, this study explores the effects of both perturbative and nonperturbative QCD on jet formation and structure. The angular differences betwee

Introduction: HIV guidelines recommend switching from a three-drug regimen (3DR) to dolutegravir + lamivudine (DTG+3TC) for eligible individuals. This retrospective national cohort study used Swedish InfCareHIV registry data to evaluate long-term outcomes of adults with HIV RNA <50 copies/ml who switched to DTG+3TC or a guideline-recommended 3DR between July 2019 and May 2023 in routine clinical c

The bioeconomy promises to replace fossil resources with renewable biomass, assigning forests a central role in sustainability transitions. This dissertation tests that promise against the empirical record, using SWINNO, a database of significant commercialized innovations in Sweden linked to firm-register data, to trace fifty years (1970–2021) of forest-related innovation output. Four papers inve

The pathophysiology underlying various manifestations of cerebral small-vessel disease (cSVD) remains poorly understood. Using high-throughput proteomics, we identified common and distinct proteomic signatures of white matter lesions (WMLs), microbleeds, infarcts and their subtypes, measured in 1,670 living patients. Across all cSVD manifestations, markers of extracellular matrix dysregulation and

This doctoral thesis investigates mediaeval earthenware production, distribution and consumption based on material from Lund, Sweden, moving beyond simple technological shifts to explore the interplay of material factors, social practices, and economic influences. It presents a typology of hard greyware, redware and glazed redware, as well as the chemical analysis of circa 400 samples. The study a

Background: Fragrance allergens are a leading cause of contact allergy (CA). Linalool, common in cosmetics and household products, forms sensitising hydroperoxides (Lin-OOH) upon air exposure. Lin-OOH is linked to a high prevalence (3.9%–11.7%) of positive patch test results, but often gives rise to doubtful or irritant reactions. Objectives: To reassess patch test concentrations of Lin-OOH, deter
