A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8 TeV collected with the ATLAS detector at the Large Hadron Collider. The samples used for this search were collected in 2012 and correspond to integrated luminosities in the range 19.5-20.3 fb
Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of atrial fibrillation (AF). Clinical evidence, however, is insufficient. We recorded monophasic action potentials (MAP) during AF from one to three sites in the right atrium in seven patients with chronic AF (CAF) and in 11 patients with paroxysmal AF (PAF). The fibrillatory (FF)
A minimal food web model was constructed comprising one grazing and one detritus food chain coupled by nutrient cycling and generalist carnivores to investigate how prey preference by carnivores may affect the strength of trophic cascades across a gradient of nutrient enrichment. The equilibrium or mean abundance of each food web component and the magnitude of the carnivore effect on lower trophic
Treatment of haemophilia A/B patients comprises factor VIII (FVIII) or factor IX (FIX) concentrate replacement therapy, respectively. FVIII and FIX activity levels can be measured in clinical laboratories using one-stage activated partial thromboplastin time (aPTT)-based clotting or two-stage chromogenic factor activity assays. We discuss strengths and limitations of these assays, providing exampl
A search for non-resonant Higgs boson pair production, as predicted by the Standard Model, is presented, where one of the Higgs bosons decays via the H→bb channel and the other via one of the H→WW⁎/ZZ⁎/ττ channels. The analysis selection requires events to have at least two b-tagged jets and exactly two leptons (electrons or muons) with opposite electric charge in the final state. Candidate events
During the last decades there has been an ever-increasing amount of democratic transitions taking place all over the world. In connection to this phenomenon, transitional justice has developed as a subfield in post-conflict peacebuilding, dealing with the judicial aspect of transitions. In applying theoretical constituents of transitional justice, this study examines the concepts of lustration (i.
This study aims to identify the key leverage points of local tourism on Öland in which work can be initiated to bring about a more sustainable development of the tourism industry. To achieve this, an analysis was made of the tourism industry on Öland, and a methodological framework called The Öland Model developed for the initiation of a project to stimulate thinking among the actors on the island
Why has neither the EU nor the United States been able to conclude an agreement on free trade with Mercosur? Many factors have affected the negotiation process and its outcome, and one of them is the role of Brazil. The aim of this thesis is to describe and to explain which factors, based on different theoretical concepts that have influenced the Brazilian foreign policy towards the negotiations b
Photoluminescence (PL) spectra from thin films (TFs) and bulk crystals (BCs) of hybrid organo-halide perovskites are significantly different, the origin of which and their impact on the efficiency of the perovskite-based photoactive devices have been debated. We have used two-photon PL to study the temperature-dependent changes in the spectra of the TFs and the BCs of methylammonium lead bromide (
When a drop impinges onto a wall heated above the Leidenfrost temperature, a very thin vapor film is formed at the interface between the liquid and the solid substrate. This vapor layer modifies the impact behavior of the drop and induces a significant decrease in heat transfer. A model is proposed for the growth of this vapor layer and its resistance to the heat transfer. The main assumptions are
Min avhandling är en undersökning av civilsamhälleliga aktörers vardagliga erfarenheter av hur väpnad konflikt, utvinningsindustri och motstånd har format det colombianska Andinoamazonia under landets pågående fredsbyggande process. Trots ett tjugotal fredsavtal och undertecknandet av ett övergripande avtal 2016 har Colombias långvariga väpnade konflikt inte upphört. Det colombianska AndinoamazoniMy thesis is an inquiry into the daily experiences of civil society actors in relation to how armed conflict, extractivism, and resistance shaped the Colombian Andinoamazonia during the country’s current peacebuilding cycle. Despite two dozen peace agreements, and the signing of a comprehensive agreement in 2016, Colombia’s protracted armed conflict did not end. The Colombian Andinoamazonia, a bio
In 1993 the 73rd Amendment to the Indian Constitution came into force, affecting the Indian rural governing bodies, the Panchayati Raj Institutions (PRIs). The Amendment, at focal point for this thesis, provides a 33% reservation for women as members and as chairperson in the PRI's three-tier system. The reservation has led to a tremendous mobilization of women in the countryside, resulting in
