Historical slag dumps are of increasing interest due to economic, environmental or archaeological reasons. Geophysical investigations can help accessing the potential reuse of slag material to recover metallic raw material or for the estimation of the hazard potential of the buried slag material due to dissolution occurrence.In our study, we have investigated various slag material in the laborator
Induced polarization (IP) is an acknowledged method in ore exploration and can be applied to evaluate the metal content in dumps containing the residues of ore processing facilities. Existing models explain the relationships between ore content and grain size of the ore particles with IP parameters. However, the models assume full water saturation of the ore containing samples, which is often not
During the 2021, there has been a noticeable increase in copper prices, with the consequent analysis of whether this value will be sustained over time and how the current price compares with their historical values. In the present research note, the relevance of the current price as exceptional fact is under question. Moreover, several lines of research are proposed in which economic history could
Two-particle long-range azimuthal correlations are measured in photonuclear collisions using 1.7nb-1 of 5.02 TeV Pb+Pb collision data collected by the ATLAS experiment at the CERN Large Hadron Collider. Candidate events are selected using a dedicated high-multiplicity photonuclear event trigger, a combination of information from the zero-degree calorimeters and forward calorimeters, and from pseud
The first measurement of the cross section for coherent J/ψ photoproduction as a function of |t|, the square of the momentum transferred between the incoming and outgoing target nucleus, is presented. The data were measured with the ALICE detector in ultra-peripheral Pb–Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02TeV with the J/ψ produced in the central rapidity region |y|<0.
This article discusses the benefits and challenges of adding participant-producedphotographs to qualitative interviewing. The analysis is based on twoqualitative studies aimed at improving the understanding of how residentsexperience and use their a) luminaires and b) window openings. A conveniencesample (N = 12) was asked to take photographs of all luminaires intheir apartments. Facilitated by th
This thesis work was aimed to investigate dynamical processes in atoms and molecules on ultrafast time scales initiated by absorption of light in the extreme ultraviolet (XUV) regime. In particular, photoionization and photodissociation have been studied using pump-probe techniques involving ultrafast laser pulses. Such pulses are generated using either high-order harmonic generation (HHG) or free
Personalized case conceptualization is often regarded as a prerequisite for treatment success in psychotherapy for patients with comorbidity. This article presents Perceived Causal Networks, a novel method in which patients rate perceived causal relations among behavioral and emotional problems. First, 231 respondents screening positive for depression completed an online Perceived Causal Networks
This is an article about the blurred borders between fiction and ‘fact’, between science and humbug, and between different ways of reading. Unexpected modes of consuming texts are explored; transposition of the senses, Jules Romain’s theories of la vision extra-rétinienne and le sens paroptique, and the famous Rosa Kuleshova’s dermo-optical perception.
Testing of autonomous vehicles involves enormous challenges for the automotive industry. The number of real-world driving scenarios is extremely large, and choosing effective test scenarios is essential, as well as combining simulated and real world testing. We present an industrial workbench of tools and workflows to generate efficient and effective test scenarios for active safety and autonomous
A search for charged Higgs bosons decaying into W±W± or W±Z bosons is performed, involving experimental signatures with two leptons of the same charge, or three or four leptons with a variety of charge combinations, missing transverse momentum and jets. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider betwe
DevOps represent the tight connection between development and operations. To address challenges that arise on the bor- derline between development and operations, we conducted a study in collaboration with a Swedish company responsible for ticket management and sales in public transportation. The aim of our study was to explore and describe the existing DevOps environment, as well as to identify h
Texten vann första pris i tidskriften Biblis Essaytävling år 2000. Den behandlar relationen mellan det abstrakta verket och den konkreta boken samt bokbandets betydelse för boken. Essän visar hur dessa frågor omsatts i passager hos Enrique Vila-Matas, Franz Schuh, Walter Benjamin m fl samt förhåller sig till idéer som bokvägningsmaskinen hos shandyisterna och Werner Hamachers rader om att allt läs
An indoor localization system for positioning evacuating people can be anticipated to increase the chances of a safe evacuation and effective rescue intervention in case of a tunnel fire. Such a system may utilize prevalent wireless technologies, e.g., Bluetooth, RFID and Wi-Fi, which today are used to survey incoming and outgoing traffic to a certain space or location, to estimate group sizes and
