Coupled and uncoupled nonlinear elastic finite element models formonotonically loaded sheathing-to-framing joints in timber based shear walls

Four different elastic models for sheathing-to-framing connections are presented and evaluated on asingle connection level and on a shear wall level. Since the models are elastic in their nature they aresuitable mainly for cases where the sheathing-to-framing connections are subjected to monotonicallyincreasing displacements. Of the four models one is uncoupled and the others are coupled with r

Book-to-Market and Size Effect: Compensations for risks or outcomes of market inefficiencies

We employ the optimal orthogonal portfolio approach to investigate if the size and book-to-market effects in US data are related to risk factors beside the market risk. This method enables us to estimate the upper limit of the risk premium, due to observed as well as all possible unobserved factors, which can be derived from a linear asset pricing model. As a corollary, it is possible to divide th

delta C-13 chemostratigraphy in the upper Tremadocian through lower Katian (Ordovician) carbonate succession of the Siljan district, central Sweden

Based on delta C-13 data from two drillcores recovered from the Siljan district, we present a first continuous carbon isotope record of the upper Tremadocian-lower Katian limestone succession of central Sweden. New names for some isotopic carbon excursions from the Cambrian-Ordovician boundary through the basal Darriwilian are introduced. The Mora 001 core from the western part of the Siljan impac

Plasma HDL cholesterol and risk of myocardial infarction: a mendelian randomisation study

Background High plasma HDL cholesterol is associated with reduced risk of myocardial infarction, but whether this association is causal is unclear. Exploiting the fact that genotypes are randomly assigned at meiosis, are independent of non-genetic confounding, and are unmodified by disease processes, mendelian randomisation can be used to test the hypothesis that the association of a plasma biomar

Stochastic differential mixed-effects models

Stochastic differential equations have been shown useful in describing random continuous time processes. Biomedical experiments often imply repeated measurements on a series of experimental units and differences between units can be represented by incorporating random effects into the model. When both system noise and random effects are considered, stochastic differential mixed-effects models ensu

Measurement of the inclusive jet cross-section in proton-proton collisions at root s=7 TeV using 4.5 fb(-1) of data with the ATLAS detector

The inclusive jet cross-section is measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using a data set corresponding to an integrated luminosity of 4.5 fb(-1) collected with the ATLAS detector at the Large Hadron Collider in 2011. Jets are identified using the anti-k(t) algorithm with radius parameter values of 0.4 and 0.6. The double-differential cross-sections are presented

Alpha 1-antitrypsin: A Role in Cancer Progression

Popular Abstract in Swedish Alpha1-antitrypsin (AAT), som är ett cirkulerande glykoprotein, är den vanligast förekommande serinproteinashämmaren i plasman hos människa. Den ingår i gruppen av akutfasproteiner, och dess halt i plasma kan snabbt öka till koncentrationer överstigande 50 mM vid inflammation, infektion eller malign sjukdom. Då AAT fungerar som en effektiv hämmare av neutrofilelastas ocAlpha1-antitrypsin (AAT), a circulating single-chain glycoprotein is the most abundant serine proteinase inhibitor in human plasma. AAT is an acute phase protein, its levels increase rapidly to concentrations exceeding 50mM in response to inflammation, infection and malignant diseases. Since AAT is a powerful inhibitor of neutrophil elastase and proteinase 3, it is generally assumed that its physi

Mimicking Photosystem II with Manganese Model Complexes to Approach Artificial Photosynthesis

Popular Abstract in Swedish Vi går mot ett mer och mer energikrävande samhälle. För att klara ett ökande behov av energi med de begränsande naturresurser som finns på jorden, har ett forskningsprojekt, som denna avhandling är en del av, som mål att utveckla artificiell fotosyntes. Den naturliga fotosyntesen använder sig av solljus för att omvandla koldioxid och vatten till energirika produkter såsThe work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. The chlorophyll complex P680 absorbs light and electrons are tr

A comparison of airborne wear particle emission models based on metro station measurements

The main sources of non-exhaust particles around metro systems are the wear from wheel-rail contact, brake contact and the contact between mechanical parts in electric power systems. In order to predict the PM10 levels on underground metro platforms, the relation among time, train frequency and PM10 level should be investigated. Two types of particle emission models have previously been published

Relationship between neural response and adaptation selectivity to form and color : An ERP study

Adaptation is widely used as a tool for studying selectivity to visual features. In these studies it is usually assumed that the loci of feature selective neural responses and adaptation coincide. We used an adaptation paradigm to investigate the relationship between response and adaptation selectivity in event-related potentials (ERPs). ERPs were evoked by the presentation of colored Glass patter

Observation of the associated production of a top quark and a Z boson in pp collisions at √s = 13 TeV with the ATLAS detector

Single top-quark production in association with a Z boson, where the Z boson decays to a pair of charged leptons, is measured in the trilepton channel. The proton-proton collision data collected by the ATLAS experiment from 2015 to 2018 at a centre-of-mass energy of 13 TeV are used, corresponding to an integrated luminosity of 139 fb−1. Events containing three isolated charged leptons (electrons o

Changes of the uterine proteoglycan distribution at term pregnancy and during labour

Objective: To characterise uterine proteoglycans and changes therein during pregnancy and labour. Study Design: Uterine samples were collected from 6 non-pregnant, 10 term-pregnant and from 10 women in active tabour. The proteoglycans were extracted by 4 M guanidine hydrochloride and precipitated with Alcian Blue. They were separated by electrophoresis and identified by Western blotting. Results:

Animal colour vision - behavioural tests and physiological concepts

Over a century ago workers such as J. Lubbock and K. von Frisch developed behavioural criteria for establishing that non-human animals see colour. Many animals in most phyla have since then been shown to have colour vision. Colour is used for specific behaviours, such as phototaxis and object recognition, while other behaviours such as motion detection are colour blind. Having established the exis

The Nav1.2 channel is regulated by GSK3

BACKGROUND: Phosphorylation plays an essential role in regulating voltage-gated sodium (Na(v)) channels and excitability. Yet, a surprisingly limited number of kinases have been identified as regulators of Na(v) channels. We posited that glycogen synthase kinase 3 (GSK3), a critical kinase found associated with numerous brain disorders, might directly regulate neuronal Na(v) channels.METHODS: We u

Explaining Modes of Participation. A Dynamic Test of Alternative Rational Choice Models

Rational choice accounts of political participation identify two major solutions to “the paradox of participation” — collective incentives and selective incentives. Prior findings regarding the viability of these solutions are seemingly inconclusive and contradictory. In our view, one important reason for this is that the applicability of these solutions varies across participatory modes. In this

Second primary malignancies in patients with male breast cancer

An international multicentre study of first and second primary neoplasms associated with male breast cancer was carried out by pooling data from 13 cancer registries. Among a total of 3409 men with primary breast cancer, 426 (12.5%) developed a second neoplasia; other than breast cancer, a 34% overall excess risk of second primary neoplasia, affecting the small intestine (standardised incidence ra

Behind the “Failed Revolution” : Becoming Patriots, or the Work of Shame in Belarusian Protests

This article looks at the politics of shame in relation to the suppressed protests of December 2010 that challenged the re-election of Aliaksandr Lukashenka as president of Belarus (1994–present). My empirical data consist of independent media publications, blog posts, and interviews that speak of “shame” as an emotional response to the protest, its aftermath, and its general context. The article
