Researchers have long discussed whether Scandinavian rock art reflects narratives. Their interpretations have frequently been based on inspections of rock art panels combined with knowledge from ethnographic and historical sources. Here, the authors adopt a more focused narratological approach that takes the concept of (visual) narrativity into consideration and draws on studies by literary analys

The ATLAS experiment at the Large Hadron Collider (LHC) employs a trigger system consisting of a first-level hardware trigger (L1) and a software-based high-level trigger. The L1 muon trigger system selects muon candidates, assigns them to the correct LHC bunch crossing and classifies them into one of six transverse-momentum threshold classes. The L1 muon trigger system uses resistive-plate chambe

The results of a search for gluino and squark pair production with the pairs decaying via the lightest charginos into a final state consisting of two W bosons, the lightest neutralinos (χ~10), and quarks, are presented: the signal is characterised by the presence of a single charged lepton (e± or μ±) from a W boson decay, jets, and missing transverse momentum. The analysis is performed using 139 f

Measurements of four-lepton differential and integrated fiducial cross-sections in events with two same-flavour, opposite-charge electron or muon pairs are presented. The data correspond to 139 fb−1 of s = 13 TeV proton-proton collisions, collected by the ATLAS detector during Run 2 of the Large Hadron Collider (2015–2018). The final state has contributions from a number of interesting Standard Mo

The first measurement of the production of pions, kaons, (anti-)protons and ϕ mesons at midrapidity in Xe–Xe collisions at sNN=5.44TeV is presented. Transverse momentum (pT) spectra and pT-integrated yields are extracted in several centrality intervals bridging from p–Pb to mid-central Pb–Pb collisions in terms of final-state multiplicity. The study of Xe–Xe and Pb–Pb collisions allows systems at

Granular activated carbon (GAC) filters can be used to reduce emissions of organic micropollutants via municipal wastewater, but it is still uncertain to which extent biological degradation contributes to their removal in GAC filters. 14C-labeled organic micropollutants were therefore used to distinguish degradation from adsorption in a GAC-filter media with associated biofilm. The rates and exten

Homogenous charge compression ignition engines have been studied as an alternative to the conventional diesel combustion to attain high efficiency with ultra-low NOx and soot emissions for a wide variety of fuels. However, its usage in real applications has been restricted due to the difficulties regarding combustion control and operating range extension. The modification of the fuel characteristi

I denna uppsats studeras socialdemokratiska kvinnors organisering och kampanjmetoder vid tiden för den allmänna och lika rösträttens införande. Undersökningen visar att erfarna kvinnliga agitatorer var mycket efterfrågade och ger exempel på kvinnoförbundets strategier för att trots begränsade resurser ordna talarturnéer. I den skriftliga agitationen tilltalades kvinnliga väljare både som del av et

Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common neurodegenerative diseases in the world. It has been possible to identify common denominators for AD and PD, including aggregation of the amyloid proteins amyloid-beta (Aβ) and alpha-synuclein (α-syn). Given the continued challenges in finding therapies that could stop or prevent proteinopathies such as AD or PD, it is appar

He II or superfluid helium, which already plays an important role in the cooling of superconducting magnets and superconducting radiofrequency cavities, has now also inspired music. Composer Michael Edward Edgerton, a professor at Lund University’s Malmo Academy of Music in Sweden has written an innovative piece, “Der Rufer,” for a percussion quartet based on phenomena found in He II including: an

OBJECTIVES: Type I IFN (IFN-I) activation is a prominent feature of primary SS (pSS), SLE, and SSc. Ultrasensitive single-molecule array (Simoa) technology has facilitated the measurement of subfemtomolar concentrations of IFNs. Here, we aimed to measure IFNα2 in serum from pSS, SLE, and SSc using a Simoa immunoassay and correlate these levels to blood IFN-stimulated gene (ISG) expression and dise

Äldreomsorgen är ett fält där det finns kolliderande rättigheter.Rätten till lika omsorg för alla kan vara svår att kombinera med kraven på ett förstå den enskildes behov och att erbjuda individanpassade insatser. Inte minst i frågan om rätten till att kunna utöva sin religion och leva enligt religiösa och kulturella traditioner på ett äldreboende ställs stora krav på både verksamheter och det lok

In the Gram-positive Firmicute bacterium Bacillus subtilis, amino acid starvation induces synthesis of the alarmone (p)ppGpp by the RelA/SpoT Homolog factor Rel. This bifunctional enzyme is capable of both synthesizing and hydrolysing (p)ppGpp. To detect amino acid deficiency, Rel monitors the aminoacylation status of the ribosomal A-site tRNA by directly inspecting the tRNA's CCA end. Here we dis
