Iconoclash and the climate movement

Priceless artworks are being destroyed or, at least, they appear to be. Yet the very act of climate protest targeting these works in what could be construed as acts of vandalism are in themselves productive of new visual media through which climate concern and urgency is conveyed. This article offers reflections upon one way in which these protest actions may be conceptually understood. It does so

Trafiksäkerhetsgranskning : Genomgång av några länders manualer/riktlinjer

Fyra manualer/riktlinjer har gåtts genom enligt internationella bästa praktik kriterier. Dessa fyra manualer/riktlinjer valdes då trafiksäkerhetsgranskning som en systematisk procedur startade i England och dess grundläggande principer förfinades i Australien. Det är också av intresse hur Sveriges grannländer, Danmark och Norge har utvecklat sina egna nationella manualer.

PERFORMANCE OF PASSIVE PROTECTION OF CROSS LAMINATED TIMBER DURING STANDARD FURNACE TESTS AND NATURAL FIRES

This paper presents the results of an experimental campaign designed to compare and understand the performance of passive protection under exposure to standard furnace tests and natural fires. As part of this campaign, five natural fire experiments were performed with partially protected cross-laminated timber (CLT) compartments under a range of ventilation conditions. In all the tests, only one s

Similarity-based reasoning in conceptual spaces

Whereas the validity of deductive inferences can be characterized in terms of their logical form, this is not true for all inferences that appear pre-theoretically valid. Nonetheless, philosophers have argued that at least some of those inferences—sometimes called “similarity-based inferences” —can be given a formal treatment with the help of similarity spaces, which are mathematical spaces purpor

Effect of Chain Length on Swelling Transitions of Brodie Graphite Oxide in Liquid 1-Alcohols

Swelling is the most fundamental property of graphite oxides (GO). Here, a structural study of Brodie graphite oxide (BGO) swelling in a set of long chain 1-alcohols (named C11 to C22 according to the number of carbons) performed using synchrotron radiation X-ray diffraction at elevated temperatures is reported. Even the longest of tested alcohols (C22) is found to intercalate BGO with enormous ex

Tezepelumab decreases airway epithelial IL-33 and T2-inflammation in response to viral stimulation in patients with asthma

Background: Respiratory virus infections are main triggers of asthma exacerbations. Tezepelumab, an anti-TSLP mAb, reduces exacerbations in patients with asthma, but the effect of blocking TSLP on host epithelial resistance and tolerance to virus infection is not known. Aim: To examine effects of blocking TSLP in patients with asthma on host resistance (IFNβ, IFNλ, and viral load) and on the airwa

An Emissions Barrier Stops Spread of Harmful Emissions from a Building into the Indoor Air

An emissions barrier was used in premises with indoor air complaints due to emissions from the buildings in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood, volatile organic compounds (VOC) from PVC flooring and/or the glue used to paste the flooring onto a concrete slab, and radon from radium-containing aerated concrete.

Search for tt¯ H/ A→ tt¯ tt¯ production in the multilepton final state in proton–proton collisions at √s = 13 TeV with the ATLAS detector

A search for a new heavy scalar or pseudo-scalar Higgs boson (H/A) produced in association with a pair of top quarks, with the Higgs boson decaying into a pair of top quarks (H/A → tt¯) is reported. The search targets a final state with exactly two leptons with same-sign electric charges or at least three leptons. The analysed dataset corresponds to an integrated luminosity of 139 fb −1 of proton–

Microbially Produced Imidazole Propionate Is Associated With Heart Failure and Mortality

Background: Over the past years, it has become clear that the microbial ecosystem in the gut has a profound capacity to interact with the host through the production of a wide range of bioactive metabolites. The microbially produced metabolite imidazole propionate (ImP) is clinically and mechanistically linked with insulin resistance and type 2 diabetes, but it is unclear how ImP is associated wit

ATLAS flavour-tagging algorithms for the LHC Run 2 pp collision dataset

The flavour-tagging algorithms developed by the ATLAS Collaboration and used to analyse its dataset of s=13 TeV pp collisions from Run 2 of the Large Hadron Collider are presented. These new tagging algorithms are based on recurrent and deep neural networks, and their performance is evaluated in simulated collision events. These developments yield considerable improvements over previous jet-flavou

The Role of Global Actors in Sustainability Transitions – Tracing the Emergence of a Novel Infrastructure Paradigm in the Sanitation Sector

The literature on sustainability transitions increasingly recognizes that sectoral structures transcending national boundaries can both hinder and promote sustainability transitions. Yet there is only limited evidence on the roles of global actors in transforming entrenched socio-technical structures directly at the global scale. To explore the mechanisms of agency at the global scale, we develop

Measurements of W+W- production in decay topologies inspired by searches for electroweak supersymmetry

This paper presents a measurement of fiducial and differential cross-sections for W+W- production in proton–proton collisions at s=13 TeV with the ATLAS experiment at the Large Hadron Collider using a dataset corresponding to an integrated luminosity of 139 fb - 1 . Events with exactly one electron, one muon and no hadronic jets are studied. The fiducial region in which the measurements are perfor

Oxygenation of the Baltoscandian shelf linked to Ordovician biodiversification

Marine biodiversity increased markedly during the Ordovician Period (~487–443 million years ago). Some intervals within the Ordovician were associated with unusually rapid and prominent rises in taxonomic richness, the reasons for which remain debated. Links between increased oxygenation and biodiversification have been proposed, although supporting marine oxygen proxy data are limited. Here we pr

The environmental benefits of relocating buildings

As the climate on earth deteriorates, actions are carried out within Europe to limit the amount of hazardous emissions to lower the environmental consequences due to greenhouse gases. A significant proportion of the emissions can be linked to the construction sector and its use of virgin resources. An area with great development potential within the construction sector is linked to its management

NATURAL FIRE TESTS ON GLT COLUMNS INCLUDING THE COOLING DOWN PHASE

This paper presents the data and the results of seven fire tests performed on glue laminated timber columns in a compartment built especially for the tests and in which timber wood cribs created a so-called natural fire. These tests are part of a research programme titled "burnout resistance" to establish a new methodology to better describe performance of structural elements during the whole dura

Affording excellence : What does excellence funding do for researchers?

The ambitions to fund excellent researchers and path-breaking research unite a whole family of funding instruments ranging from Centres of Excellence to individual grants. While instruments aimed at funding excellence share a number of commonalities, there are important subsidiary features which determine their overall efficacy. The paper uses a case study of the Swedish Distinguished Professor Gr

The effect of valve design on the pressure losses in a high-pressure homogenizer : An improved pressure drop correlation for estimating gap height

Understanding how the design of high-pressure homogenizer valves influence pressure losses in the device is of general interest for performance optimizing, and of special importance for developing correlations for predicting gap heights and gap velocities. The traditionally used correlation is from 1975 and based on a limited experimental dataset on gaps that are longer and often of lower capacity

Genetic analysis of blood molecular phenotypes reveals common properties in the regulatory networks affecting complex traits

We evaluate the shared genetic regulation of mRNA molecules, proteins and metabolites derived from whole blood from 3029 human donors. We find abundant allelic heterogeneity, where multiple variants regulate a particular molecular phenotype, and pleiotropy, where a single variant associates with multiple molecular phenotypes over multiple genomic regions. The highest proportion of share genetic re

Element-resolved evidence of superdiffusive spin current arising from ultrafast demagnetization process

Using element-specific measurements of the ultrafast demagnetization of Ru/Fe65Co35 hetero-structures, we show that Ru can exhibit a significant magnetic contrast (3% asymmetry) resulting from ultrafast spin currents emanating from the demagnetization process of the FeCo layer. We use this magnetic contrast to investigate how superdiffusive spin currents are affected by the doping of heavy element
