EU-domstolens avgörande i mål C-29/08 SKF har varit föremål för mycket uppmärksamhet och diskussion sedan det kom under hösten 2009. Avgörandet gäller möjligheten att dra av ingående mervärdesskatt på tjänster förvärvade för att genomföra försäljning av aktier i dotterbolag I denna uppsats har EU-domstolens SKF-dom stått i centrum. Den har att satts in i ett perspektiv och analyserats mot bakgrun
Denna studie intresserar sig för när en organisations förtroende sätts på spel. Kriskommunikation är i fokus och mer specifikt hur modejätten NA-KD har hanterat ett försök till bojkott, vilket kan kopplas till det aktuella fenomenet cancel culture. Studiens primära syfte handlar om att öka förståelsen för hur organisationer som utsätts för en liknande kris online kan hantera dessa med hjälp av resThis study is interested in when an organization's trust is exposed. Crisis communication is in focus and more specifically how the fashion giant NA-KD has handled an attempt to boycott, which can be linked to the current phenomenon of cancel culture. The primary purpose of the study is to increase the understanding of how organizations that are exposed to a similar crisis online can handle th
In this paper the Poisson bracket algebra for the open massless relativistic string in the one-space-and one-time-dimensional case is considered. In order to characterize the orbit of the system the directrix function, i.e., the orbit of one of the endpoints of the string, is used. It turns out that the Poisson bracket algebra is of a very simple form in terms of the parameters of the directrix fu
This thesis considers the low-energy effective field theory of a new technicolor extension. The extension preserves the Standard Model Higgs boson and introduces a chirally symmetric technifermion sector, in the framework of the gauged linear sigma model. In the nearly conformal limit, the considered extension leads to a common origin of the Higgs- and Technisigma vacuum expectation values, relate
In this thesis, a holographic model for quantum chromodynamics (QCD) is used to estimate the electromagnetic contribution to the kaon mass difference. The principal ideas of the model are inspired by the AdS/CFT correspondence, which is believed to be exact. The calculation is first performed theoretically, highlighting the expansion of the result into a diagrammatic structure referred to as Witte
New stable particles with fairly low masses could exist if the coupling to the Standard Model is weak, and with suitable parameters they might be possible to produce at the LHC. Here we study a selection of models with the new particles being charged under a new gauge group, either U(1) or SU(N). In the Abelian case there will be radiation of gammavs, which decay back into the SM. In the non-Abeli
Heavy long-lived quarks, i.e. charm and bottom, are frequently studied both as tests of QCD and as probes for other physics aspects within and beyond the standard model. The long lifetime implies that charm and bottom hadrons are formed and observed. This hadronization process cannot be studied in isolation, but depends on the production environment. Within the framework of the string model, a maj
We study the thermodynamic behavior of a simple off-lattice model for protein folding. The model is two dimensional and has two different "amino acids." Using numerical simulations of all chains containing eight or ten monomers, we examine the sequence dependence at a fixed temperature. It is shown that only a few of the chains exist in unique folded state at this temperature, and the energy level
Standardmodellen är det teoretiska ramverk som beskriver partikelväxelverkningar på subatomär nivå. För att bekräfta teorins förutsägelser behöver experimentella data samlas in. I partikelfysik kan information om hur partiklar produceras och växelverkar med varandra erhållas genom att accelerara partiklar till höga energier och sedan låta dem kollidera. Detta är skälet att partikelkolliderarIn this Master thesis, two directions have been explored to improve the current parton shower algorithm of the event generator Pythia. Firstly, three choices of transverse-momentum-ordered evolution variable have been studied for final-state radiation in order to allow more flexibility within the algorithm. These three choices turn out to be valid but they lead to more technical implementations th
“Getting into the Swedish society can be difficult if you're coming from outside the EU”, says Ganna Petruk. Her Jobbsprånget trainee Shabnam Parveen agrees: “I hope this will open doors for me in the future”. Shabnam Parveen came to Sweden from India a little over two years ago with her husband and son. She was recommended Jobsprånget from the Swedish Public Employment Service (Arbetsförmedlingen

We test a new approach to calculate the mean velocity and velocity dispersion for a sample of nearby stars when their radial velocities are not available. The most commonly used method (here called the projection method, PM) was introduced in a paper by Dehnen & Binney (1998). That method is here compared, theoretically and numerically, with an application of the Maximum Likelihood (ML) method
We discuss some important issues concerning multiplicities in quark and gluon jets in e+e- annihilation. In QCD the properties of a jet in general depend on two scales, the energy and virtuality of the jet. Frequently theoretical predictions apply to a situation where these scales coincide, while for experimental data they are often different. Thus an analysis to extract e.g. the asymptotic multip
The recent experimental measurement of the muon g−2 at Fermilab National Laboratory, at a 4.2σ tension with the Standard Model prediction, highlights the need for further improvements on the theoretical uncertainties associated to the hadronic sector. In the framework of the operator product expansion in the presence of a background feld, the short-distance behaviour of the hadronic light-by-light
