In 2019 October Betelgeuse began a decline in V-band brightness that went beyond the minimum expected from its quasi-periodic ∼420 day cycle, becoming the faintest in recorded photometric history. Observations obtained in 2019 December with Very Large Telescope/SPHERE have shown that the southern half of the star has become markedly fainter than in 2019 January, indicating that a major change has
The production of a prompt photon in association with a Z boson is studied in proton-proton collisions at a centre-of-mass energy s = 13 TeV. The analysis uses a data sample with an integrated luminosity of 139 fb−1 collected by the ATLAS detector at the LHC from 2015 to 2018. The production cross-section for the process pp → ℓ+ℓ−γ + X (ℓ = e, μ) is measured within a fiducial phase-space region de
The objective of this paper is to describe the evaluation and effects of a major reconstruction of an arterial street in Eskilstuna, a medium sized Swedish town. The aim of the reconstruction was to minimize the barrier effects of the arterial street and by that create a stronger connection between the town center, on one side of the street, and the town-river, on the other; but also to create gen
Developing an ability to independently formulate research questions is an important goal in doctoral education. During a seminar in the “Docent course”, accredited by Genombrottet at Lund University, the authors behind this paper ended up in a discussion on the actual conditions for developing such ability. During the discussions, the authors, based on their own experiences, identified several con
This article assesses how Swedish parliamentary democracy works today, almost one hundred years into its history. Our main research question is whether the transformation of the Swedish party system since the 1980s—and especially since 2010, when the populist-radical-right Sweden Democrats entered parliament—has altered the way parliamentary democracy works. We provide new evidence on Sweden’s cha
GDPR har fått en betydande påverkan på företag och organisationers arbete med dataskydd och utvecklats till en central aspekt att beakta vid företagsförvärv. Trots detta har betydelsen av GDPR i transaktionssammanhang fått ytterst lite uppmärksamhet i den svenska doktrinen. I uppsatsen granskas översiktligt de risker som GDPR innebär vid företagsförvärv, särskilt med avseende på risken för förväThe GDPR has had a significant impact on how companies and organisations work with data protection and has developed into a central aspect to consider in corporate acquisitions. Despite this, the importance of the GDPR in transactional contexts has received very little attention in the Swedish literature. The thesis provides an overview of the risks that the GDPR entails in the context of corpor
Energy efficiency programmes (EEPs) are schemes operated by utilities or other bodies in order to incentivize energy efficiency improvement, in particular by adoption of energy-efficient products and typically by means of an economic reward. Ample experience has been gained, especially in the U.S., where EEPs have been in use for decades, with the rationale of avoiding additional energy supply by
Coffee is the most common drink in the world, second only to water. This makes caffeine, the ingredient of coffee known for its wakefulness-promoting effects, one of the most used psychoactive substances. The psychoactive property of caffeine is well-characterized, and entails its interaction with the adenosine receptors, involved in sleep regulation. While studies have shown a deleterious immedia
This thesis investigates probing antennas within a small shielded test enclosure for IoT, Internet of Things, products for the detection of manufacturing deviations. The small enclosure forces the transmitter and receiver to be in the near-field. Shielding of the enclosure additionally generates a multipath environment, which becomes sensitive to displacements of objects such as wires or metallic
Den fackliga organisationsgraden är fortfarande mycket hög i Sverige. Sedan de svenska a-kasseavgifterna höjts kraftigt 2007 inträffade ett fackligt medlemsras utan motsvarighet i Sveriges moderna historia. Arbetsgivarnas organisationsgrad (definierad som andelen löntagare i företag och förvaltningar som tillhör en arbetsgivarorganisation) är numera betydligt högre än löntagarnas. Artikeln redovis
The neurobiological basis and temporal dynamics of communicative language processing pose important yet unresolved questions. It has previously been suggested that comprehension of the communicative function of an utterance, i.e. the so-called speech act, is supported by an ensemble of neural networks, comprising lexico-semantic, action and mirror neuron as well as theory of mind circuits, all act
Prenatal testosterone surge is considered crucial for physiological masculinization of male progeny. Disorders in sex steroid hormone balance during the fetal development may interfere with male reproductive health later in life. In this study, we have investigated in utero and in vitro effects of flutamide (FLU) and diethylstilbestrol (DES) on fetal rat testicular steroidogenesis. In utero exposu
We have studied the influence of three different fullerene derivatives on the charge generation and recombination dynamics of polymer/fullerene bulk heterojunction (BHJ) solar cell blends. Charge generation in APFO3/[70]PCBM and APFO3/[60]PCBM is very similar and somewhat slower than charge generation in APFO3/[70]BTPF. This difference qualitatively matches the trend in free energy change of elect
This report is part of the National evaluation of the Swedish compulsory school. The evaluation was conducted by the National Board of Education in 2003. The present report deals with pupils' attitudes to History as a subject and to history education in the 9th grade. We have also made an evaluation of pupils' knowledge of history. The survey shows that a majority of the pupils have positive views
Popular Abstract in Swedish Denna avhandling behandlar storlekskarakterisering av stora molekyler (polymerer) med en ny teknik, nämligen flödesfältflödesfraktionering (flödesFFF). Det aktuella storleksområdet som studerats i avhandlingen är intervallet mellan några få nanometer(nm) upp till en halv mikrometer (um). Storleksbestämningen med flödesFFF baseras på en separation av material med olika dSize, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. In this thesis, a relatively novel technique, asymmetrical flow field-flow fractionation (flow FF
The spoilage flora of refrigerated raw and pasteurized milk was classified and identified by numerical phenotypic analysis. Isolations of bacteria were made at a defined spoilage stage, when the total aerobic count was 106-107 cfu per ml. The secondary flora of ripened Swedish and Norwegian cheeses was investigated by numerical analysis. Aeromonas and Enterobacteriaceae spp. isolated from the spoi
In northern peatlands the thawing of permafrost increasing the active layer depth and changing the hydrology may lead to feedbacks in the climate system through changes in the biogeochemistry of carbon. We are examining this association on the Stordalen peatland complex in subarctic Sweden by analyzing a DEM derived from LiDAR-data and the calculated TWI. The DEM, with a spatial resolution of 1 m,
Popular Abstract in English Prostate cancer is one of the most common cancers in the world and the second most common in men. The western world has the highest incidence rates. The causes of prostate cancer are not yet clear, however a number of risk factors have been identified such as familial history, ethnicity, diet and genetic events. Prostate cancer affects primarily elderly men with the majProstate cancer is the second most common cancer in men. In order to improve diagnosis and prognosis, new sensitive and specific biomarkers are needed. Tissue biomarkers carry expression and morphological information of the tissue where they are expressed. However their use is still limited by technological problems, lack of standardized procedures and inadequate interpretation. In this work we in
