Critically exploring the potential affective atmospheres of climate change : The case of Greenland

There is widespread criticism that place marketing initiatives contribute mainly to the commodification of places (Lichrou and Panayiotopoulos, 2021; Kavaratizis et al., 2018; Kavaratzis et al., 2017) and to the commodification of the climate crisis (Fletcher 2019). Place marketing is seen here only as a strategic management tool to make a place recognisable in the minds of different stakeholders,

Ablating Boundaries, Sparking the Future of Materials : Engineering of Bimetallic Nanoparticles via Spark Ablation

Bimetallic nanoparticles exhibit unique physicochemical characteristics that often translateinto functional properties surpassing those of their monometallic counterparts. The abilityto precisely tailor these characteristics enables fine-tuning of their properties for targetedapplications. This doctoral thesis investigates the engineering of bimetallic nanoparticlesvia spark ablation, a continuous

Chemical kinetics study of nitrogen-containing fuels in flames – experiments and modeling

Climate change is strongly linked to the quantity of carbon dioxide (CO2) released by burning fossil fuels, which contain carbon. To address the problem, ammonia (NH3) has recently gained significant attention as a potential alternative fuel due to its carbon-free nature, ease of storage, and good energy density. However, ammonia combustion in practical devices presents challenges, particularly it

Rapporten undersøger, hvordan streaming påvirker danske forfatteres økonomi og vilkår med fokus på forskelle mellem genrer, udgivelsesstrategier og markedspositioner. Streaming medfører overordnet, at man går fra sælge en vare (en bog) i boghandlen, til at sælge adgang til et katalog af bogtitler på en streamingplatform. Forlag og forfattere får betaling for værket baseret på brug, det vil sige, h

Time-dependent diffusion MRI with free gradient waveforms: From theory development to initial applications

Diffusion magnetic resonance imaging (dMRI) is a powerful non-invasive technique for probing tissuemicrostructure. While highly sensitive, conventional dMRI methods suffer from low specificity, due in part toexperimental designs that conflate multiple contrast mechanisms. This thesis aims to address these limitations bydeveloping advanced time-dependent dMRI techniques to disentangle competing sou

Structural interplay in block copolymer-bile salt complexes : from globules to ribbons

The supramolecular structures resulting from the complexation between the neutral-cationic block copolymer poly(ethylene oxide)- block-poly(2-(trimethylammonium)ethyl methacrylate iodide) (PEO 114- b-PTMAEMAI 95) and the bile salt sodium deoxycholate (NaDC) were investigated by dynamic light scattering, small-angle X-ray scattering, cryogenic transmission electron microscopy and proton NMR techniq

Nationwide Observational Case–Control Study of Risk Factors for Aerococcus Bloodstream Infections, Sweden

Risk factors for developing bloodstream infections (BSIs) caused by Aerococcus bacteria remain insufficiently examined. In this nationwide case–control study in Sweden, 19 of 23 clinical microbiological laboratories identified patients who had aerococcal BSIs during 2012–2016. We compared each of those index patients with 4 controls matched for age, sex, and county of residence. Overall, 588 episo

An adaptive finite difference method for total variation minimization

In this paper, we propose an adaptive finite difference scheme in order to numerically solve total variation type problems for image processing tasks. The automatic generation of the grid relies on indicators derived from a local estimation of the primal-dual gap error. This process leads in general to a non-uniform grid for which we introduce an adjusted finite difference method. Further we quant

Stress-Testing a Quasi-Market: Unintended Consequences of the Swedish School Voucher System

Quasi-markets in the provision of public services are increasingly common but also highly contested. We formulate a conceptual framework based on economic theory to describe how quasi-markets differ from traditional markets in five aspects: 1) revenues, costs, and profits; 2) the matching of supply and demand; 3) competition; 4) structural change; and 5) rent-seeking. Using the assumption of profi

Vad hände med Sveriges reformförmåga?

Under slutet av 1900-talet var den svenska reformtakten hög vilket gjorde ekonomin konkurrenskraftig och att Sverige klarade finanskrisen 2008–2010 bättre än jämförbara länder. Nu har reformtakten avtagit och den ekonomiska friheten är fallande på flera områden. I en ny rapport från Entreprenörskapsforum konstateras att 2010-talet blev ett i allt väsentligt förlorat decennium med minskad ekonomisk

Mapping molecular complexes with super-resolution microscopy and single-particle analysis

Understanding the structure of supramolecular complexes provides insight into their functional capabilities and how they can be modulated in the context of disease. Super-resolution microscopy (SRM) excels in performing this task by resolving ultrastructural details at the nanoscale with molecular specificity. However, technical limitations, such as underlabelling, preclude its ability to provide

The Field Guide to 3D Printing in Optical Microscopy for Life Sciences

The maker movement has reached the optics labs, empowering researchers to create and modify microscope designs and imaging accessories. 3D printing has a disruptive impact on the field, improving accessibility to fabrication technologies in additive manufacturing. This approach is particularly useful for rapid, low-cost prototyping, allowing unprecedented levels of productivity and accessibility.

Parallel mapping of optical near-field interactions by molecular motor-driven quantum dots

In the vicinity of metallic nanostructures, absorption and emission rates of optical emitters can be modulated by several orders of magnitude1,2. Control of such near-field light-matter interaction is essential for applications in biosensing3, light harvesting4 and quantum communication5,6 and requires precise mapping of optical near-field interactions, for which single-emitter probes are promisin

Mapping densely packed αIIbβ3 receptors in murine blood platelets with expansion microscopy

Interrogating platelets and their densely packed, highly abundant receptor landscape is key to understand platelet clotting, a process that can save lives when stopping blood loss after an injury, but also kill when causing heart attack, stroke, or pulmonary embolism. The underlying key receptor distributions and interactions, in particular the relevance of integrin clustering, are not fully under

Sharpening emitter localization in front of a tuned mirror

Single-molecule localization microscopy (SMLM) aims for maximized precision and a high signal-to-noise ratio1. Both features can be provided by placing the emitter in front of a metal-dielectric nanocoating that acts as a tuned mirror2-4. Here, we demonstrate that a higher photon yield at a lower background on biocompatible metal-dielectric nanocoatings substantially improves SMLM performance and

Cancer Diagnoses After Recent Weight Loss

IMPORTANCE: Weight loss is common in primary care. Among individuals with recent weight loss, the rates of cancer during the subsequent 12 months are unclear compared with those without recent weight loss.OBJECTIVE: To determine the rates of subsequent cancer diagnoses over 12 months among health professionals with weight loss during the prior 2 years compared with those without recent weight loss

Sex bias in FGFR3 somatic mutations in bladder cancer

Background: Strong sex disparities have been observed among patients with bladder cancer (BCa). FGFR3 is one of the most frequently mutated genes in bladder cancer, and there are inconsistencies in its frequency in male and female patients. Methods: Here, we conducted a meta-analysis comparing the FGFR3 somatic mutation frequency in men and women among 7351 patients with BCa from 18 cohorts. Resul
