A search for the narrow structure, X(5568), reported by the D0 Collaboration in the decay sequence X→Bs0π±, Bs0→J/ψφ, is presented. The analysis is based on a data sample recorded with the ATLAS detector at the LHC corresponding to 4.9 fb-1 of pp collisions at 7 TeV and 19.5 fb-1 at 8 TeV. No significant signal was found. Upper limits on the number of signal events, with properties corresponding t
The advanced properties of modern materials originate from their nanoscale size and shape and from chemical modifications or doping. Special techniques that can measure the chemical state in the nanoscale are required for exploration and understanding the properties of these materials. While X-ray photoelectron spectroscopy (XPS) can access the necessary chemical information, conventional setups h
In October 2014, the European Council agreed on a target of improving overall energy efficiency by at least 27 per cent by 2030. According to the European Council's conclusions, this target should not be translated into nationally binding targets. Nevertheless individual Member States are free to set higher national objectives if desired. However, it is difficult to assess the degree of ambition o
The meshless radial point interpolation method (RPIM) in frequency domain for electromagnetic scattering problems is presented. This method promises high accuracy in a simple collocation approach using radial basis functions. The treatment of high-order non-reflecting boundary conditions for open waveguides is discussed and implemented up to fourth-order. RPIM allows the direct calculation of high
Objective Although important treatment decisions are made in the Emergency Department (ED), conversations about patients’ goals and values and priorities often do not occur. There is a critical need to improve the frequency of these conversations, so that ED providers can align treatment plans with these goals, values, and priorities. The Serious Illness Conversation Guide has been used in other c
The polar region is experiencing one of the most rapid environmental changes driven by atmospheric warming, and feedbacks within the cryosphere. Under such a setting, it is crucial to understand the biogeochemical cycling of the nutrient silicon (Si) in the high latitudes, which is regulating the nutrient supply to polar ecosystems, and is linked to the global carbon cycle via diatom production. H
The principle of fiscal neutrality is the essence of the EU VAT system. It aims at relieving taxable persons of the burden of VAT through the deduction mechanism provided for by the VAT Directive. In its another aspect, the principle is a means of reflecting the equal treatment of taxable persons. The equal treatment of taxable persons ensures that taxable persons in a comparable situation are not
Simulations of large detectors such as the ATLAS detector at the LHC (Large Hadron Collider) are compute-intensive projects, and are according to current internal estimates expected to be consuming 40 % of the total ATLAS CPU resources in 2020, creating a need for software optimization strategies. We investigate build configurations of the Geant4 simulation software to find if a) a performance imp
Due to insufficient knowledge on preschool teacher reporting obligations, studies show that fewer reports are made regarding children that might need help. The aim of the study was to illustrate how preschool teachers interpret and apply the law on reporting obligations in preschool activities and to illustrate the collaboration between preschool and social services. What does preschool teachers t
Around the world the rise of populist and anti-globalization forces can be seen. In Sweden this movement is prevalent as well, as the populist party the Sweden Democrats is experiencing a substantial increase in support. The reason for this is a widely debated subject amongst scholars. One potential explanation for the rise of populism could be the increased imports from China in recent years. Pre
This thesis is a conceptual study focused on the relationship between populism and conspiracy theories to see if populism poses a totalitarian threat to democracy. Starting with a discussion on democracy and populism, this thesis examines the relations between conspiracy theories and populism as well as their respective constructions. Thereafter, departing from Hannah Arendt’s book the Origins of
The Pacific Island countries face a host of unique and urgent development challenges that have historically provided the impetus for pursuing various forms of regionalism. This study seeks to shed new light on these processes by examining how the low levels of institutional and governance capacity of regional actors has influenced the success of institutional development strategies within the broa
This thesis investigates the reasons behind the continuation of legitimisation for the ruling party in Singapore, despite its undemocratic practices. The main hypothesis is that the ruling party has effectively utilised competitive authoritarianism, which involves the use of manipulation and repression to maintain control over the public and convince or pressure them to vote for the party. Through
Uppsatsen behandlar Internetkonsultbranschens utgallringsfas där företagen kämpar för sin överlevnad. Studien ser närmare på företaget Tromb Internet Solutions och fokuserar framförallt på dess interna och externa relationer. Uppsatsen tar sin utgångspunkt i Public Relationsteorin. Med hjälp av PR för att skapa kommunikation internt inom företaget, till partners och även till övriga intressenter.
Purpose: The purpose of this thesis is to clarify and evaluate the concept of scenario planning. Methodology: Our research methodology has a qualitative approach and uses deductive reasoning. The theoretical field of strategy formulation has been reviewed and in specific the concept scenario planning was unravelled and mapped. Thereafter, our model was tested in a case study where the empirical da
Denna studie åsyftar att utreda hur saltlösning påverkar vanliga slitlager i kontrast till hur luft samt vatten påverkar slitlager. Slitlagerna representerades av asfalttyperna asfaltbetong, dränerande (ABD11 70/100) vilken är en dränerande beläggning samt asfaltbetong, stenrik (ABS11 70/100) som är en tät beläggning. ABD och ABS användes i experimentet eftersom ABD har en högre hålrumshalt än ABSThis study aims to investigate how salt solution affects typical road wear courses in contrast to how air and water affect road surfaces. The wear layers are represented by the asphalt concrete Porous Asphalt (PA or ABD11 70/100) which is a draining road surface and Stone Mastic Asphalt (SMA or ABS11 70/100) which is a dense road surface. PA and SMA were used as contrasts to use in the experiment
Due to the world becoming increasingly more ambiguous and uncertain, some concepts may consequently become more relevant when evaluating ways to cope with this change. One such concept that has historical indications of being a significant factor in people’s ability to successfully cope with a changing environment is what is called the need for closure. Developed and researched by Arie W. Kruglans
