The objective of this work was to observe and quantify the onset and evolution of localised deformation processes in sand with grain-scale resolution. The key element of the proposed approach is combining state-of-the-art X-ray micro tomography imaging with three-dimensional volumetric digital image correlation techniques. This allows not only the grain-scale details of a deforming sand specimen t

How do ’clandestine’ asylum seekers experience the Swedish welfare state? How are they located in relation to welfare institutions, civil society, notions of nationhood and gender regimes? These are some questions I discuss in my work. My research project is based on an ethnographic study with ‘clandestine’ asylum seekers (rejected asylum seekers who stay in the country and ‘hide’ from police and

Organizational ambidexterity has emerged as a research area promoting innovation for both short- and long- term success. Structural ambidexterity proposes dual structures and strategies to differentiate efforts, focusing on one or the other form of innovation. In contrast, contextual ambidexterity relies on behavioral and social means to integrate exploitation and exploration. In this article we h

‘Virtual imagery as evidence in the contemporary context of the war on terror’ This paper explores the evidentiary role of virtual reproductions produced by the research project Forensic Architecture in the context of the contemporary battlefields of the war on terror. The digitization of war has created a networked landscape whose processes often remain invisible to the public. Although drone op

The decreasing oil supply, more stringent pollutant legislations and strong focus on decreasing carbon dioxide emissions drives the research of more efficient and clean combustion engines. One such combustion engine concept is Homogeneous Charge Compression Ignition (HCCI) which potentially achieves high efficiency and low NOx and soot emissions. One practical realization of HCCI in SI engines is

A systematic set of single-pass full penetration friction stir bead-on-plate and butt-welds in HSLA-65 steel were produced using a range of different traverse speeds (50 to 500 mm/min) and two tool materials (W-Re and PCBN). Microstructural analysis of the welds was carried out using optical microscopy, and hardness variations were also mapped across the weld-plate cross sections. The maximum and

In Papers One through Six we have investigated the function and integration of “new” neurons – new neurons born from neural stem cells in the adult brain, and new neurons in the sense that they were generated from fibroblasts. Papers One and Two focused on the new neurons generated from neural stem cells in the SVZ and SGZ after pathological insults. We investigated how the newly generated neuro

Background The prognosis in adults with congenital aortic valve disease is usually favourable; nevertheless, a number of medical and social factors might hamper long-term prognosis and quality of life. With a focus on physical exercise level, data from the Swedish National Registry on Congenital Heart Disease (SWEDCON) were analysed and variables associated with health-related quality of life in a

In order to study further the long-range correlations ("ridge") observed recently in p + Pb collisions at root s(NN) = 5.02 TeV, the second-order azimuthal anisotropy parameter of charged particles, v(2), has been measured with the cumulant method using the ATLAS detector at the LHC. In a data sample corresponding to an integrated luminosity of approximately 1 mu b(-1), the parameter v(2) has been

Measurements of the sphericity of primary charged particles in minimum bias proton-proton collisions at root s = 0.9, 2.76 and 7 TeV with the ALICE detector at the LHC are presented. The observable is measured in the plane perpendicular to the beam direction using primary charged tracks with p(T) > 0.5 GeV/c in vertical bar eta vertical bar < 0.8. The mean sphericity as a function of the charged p

Strength grading of Norway spruce (Picea abies (L.) Karst.) side boards in the wet state was investigated. For a sample of 58 boards, density and dynamic modulus of elasticity in the axial direction, MOE_dyn, were determined in the wet state. The boards were then split into two parts and the procedure of determining MOE_dyn was repeated both before and after the boa
