Partikelfysikens standardmodell har framgångsrikt förutsagt de nu kända elementära partiklarna och deras växelverkningar. Liksom varje fysikmodell har den ett giltighetsområde. Det okända som kan tänkas inträffa utanför detta område kallas fysik bortom standardmodellen. Nya fenomen kan förväntas uppträda vid extremt höga energier, bortom de tillgängliga vid dagens kolliderare. En av de aspekter viThe non-Abelian QCD nature allows for pp collisions to contain gluon emissions off quarks as well as gluon branchings into further gluons — a structure that can be described by the parton shower model. In this project we present the results of the impact the shower has on the reconstruction of the W-boson and top quark masses using Pythia, the Lund Monte Carlo event generator. As a warm-up, the im

Tuberculosis (TB) and other mycobacterial infections have become more difficult to treat since the strains need to be screened for resistance. Furthermore, the half-year long treatment time could harm hepatocytes as a side effect of the treatment. This calls for discovery of new compounds for a successful treatment. One such promising peptide was recently discovered and called NZX. In this study

Multi-scale modelling is a novel approach to fire modelling in situations where the size of the domain prevents it from being modelled completely in 3D. By splitting the domain in a 1D and 3D portion multi-scale modelling allows for much faster simulations which still adhere to the correct boundary conditions. In this thesis the multi-scale methodology is applied to the LHC accelerator in use at C

Visstidsanställningar har en viktig roll i strävan efter ökad flexibilitet men konsekvenserna av anställningsformens tillämpning och förekomst har länge varit omdebatterade. År 2007 inledde EU-kommissionen ett överträdelseärende efter det att TCO anmält Sverige för brister i implementeringen av visstidsdirektivet 1999/70/EG som bland annat syftar till att förhindra otillåten stapling av visstidsanFixed-term employment plays an important role in pursuing increased flexibility, but the effects of fixed-term employment through its usage and occurrence has long been a topic of debate. In 2007, the European Commission initiated infringement proceedings after TCO reported Sweden for inadequate implementation of the Fixed-Term Work Directive 1999/70/EG which alongside other purposes aims to preve

Integrering av historia i fysikundervisningen har undersökts länge och i stor omfattning internationellt. Det finns ett brett stöd för att det kan ha många önskvärda effekter på elevers lärande och motivation. Denna positiva bild verkar inte delas helt av fysiklärare och det framkommer att det finns många utmaningar med att integrera fysikhistoria i undervisningen. Syftet med denna uppsats var attIntegration of history of physics (HOP) in the teaching of physics has been studied for a long time and to a great extent. There is a widespread support of the fact that history of physics can have many desirable effects on students learning and motivation. This positive picture is seemingly not shared completely among physic teachers and to implement history to the physics classroom has been show

I samband med att företag drabbas av arbetsbrist aktualiseras arbetsgivarens skyldighet att utreda möjligheterna att erbjuda den eller de berörda arbetstagarna omplaceringar till andra befattningar i enlighet med 7 § 2 st. LAS. Denna omplaceringsskyldighet är tvingande oavsett företagets storlek och syftar till att så långt det går undvika friställningar av arbetstagare. Av lagtexten framgår att eWhen companies are suffering from labor shortages, the employer’s obligation to investigate the possibility of offering the affected employee or employees other positions in accordance with section 7 second paragraph is raised. This relocation obligation is mandatory regardless of the size of the company and aims to avoid employee layoffs as far as possible. It is clear from the legal text that a

This comparative thesis investigates in what ways municipal detailed planning of three train station areas considered perceived safety. It further examines how strengths and weaknesses in each case’s perceived safety methodology can be understood through established planning models/concepts and existing academic research on Swedish perceived safety planning. Finally, the study concludes how future

How do professional counselors understand and rationalize their responsibility to report child maltreatment when worried about a child? The aim of this study was to analyze how school counselors and health care counselors talk about their obligation to report child maltreatment to the social services, and how their reasoning affects the protection of children in Sweden. The method chosen was quali

Syftet med uppsatsen är att kritiskt belysa, analysera och diskutera turordningsreglernas rättsliga innebörd och rättspolitiska diskurs i ett svenskt och EU-rättsligt perspektiv. Lagen om anställningsskydd trädde i kraft 1974 och har allt sedan dess varit en av de mest omdiskuterade svenska lagstiftningarna. I centrum för diskussionen står turordningsreglerna. Anledningen till att frågan blivit The purpose of this thesis is to critically highlight, analyze and discuss the priority rules, their judicial meaning and legal policy discourse in a Swedish and European legal perspective. The Act on Employment came into force in 1974 and since then it has been one of the most controversial legislations in Sweden. At the very center of the debate are the priority rules. The reason that the rules

This master’s thesis aims to compare national museum in Norway and Sweden throughout different time periods. The study consists of a literary analysis of yearly reports from 1905-06 and 2010 from the open-air museums: Norsk Folkemuseum and Skansen, and the national art museums: Nationalmuseum and Nasjonalmuseum for kunst, arkitektur og design. With the dissolution of the political union between No

The use of an object-oriented approach in software engineering has proven to be successful for many years, but in the fields of mechanics and automation it has been ignored for long. The Tetra Pak Carton Bottle automation team believes that a switch from a function-oriented architecture to an object-oriented one would be of benefit not only to them but also any department which is involved with de

Bangladesh is located in a danger area of the World. The geographical location makes the country vulnerable for tropical cyclones and other hazards. An increasing number of natural disasters such as floods, storms, and tropical cyclones, always keep the coastal people in a worst condition. Bangladesh government is not always fully successful in recovering the situation and gives a sustainable live

I en allt mer globaliserad värld präglad av konstant gränsöverskridande handel är det av yttersta vikt att beskattningen av gränsöverskridande transaktioner fungerar tillfredsställande. Detta gäller även de fall då avkastning på finansiella instrument korsar länders gränser. I svensk rätt liksom i många andra länders rätt saknas klara definitioner för vad som är ränta och vad som är utdelning. DetIn a progressively more globalized world featuring constant cross-border trade it is imperative that the taxation of cross-border transactions is carried out in a satisfactory manner. This is also true regarding periodic income from financial instruments. In Swedish tax law as well as in many other countries there is no clear definition of what constitutes interest and dividends. Large multination

This thesis is about, as the title reveals, wrecks and recycling of ships. The selected angles are economic and legal aspects of the ship that has become a wreck or sent for recycling. When it comes to wreck the thesis is primarily based on the legal status of the wreck and how the shipowner can get indemnified through their insurance for a total loss. This paper concerns the two subsections of to

The paper sheds light on financial contagion within the Euro Area and Asia, and contagion from the Euro Area to Asia during two recent crises: the global financial crisis and European sovereign debt crisis. Applying the multinomial logit regression model, the paper investigates how the macro-finance variables affect the coincidence of extreme negative returns (coexceedances). In addition, I apply

How would a low-carbon energy transformation affect energy security? This paper proposes a frame- work to evaluate energy security under long-term energy scenarios generated by integrated assessment models. Energy security is defined as low vulnerability of vital energy systems, delineated along geographic and sectoral boundaries. The proposed framework considers vulnerability as a combination of

An important factor for a user of web sites on the Internet is the duration of time between the request of a web page until an answer has been returned. If this response time is too long, the user is likely to abandon the web site and search for other providers of the service. To avoid this loss of users, it is important for the web site operator to assure that users are treated sufficiently fast.
