In this work we investigate the spin correlation effect of the interference between signal and irreducible background events present in top quark pair production at the LHC at LO in the dilepton channel. To simulate the high energy proton-proton collisions of the LHC, MadGraph5_aMC@NLO framework is used as an event generator. The spin correlations are explicitly measured via the lepton kinematics

Work-related threats and violence is a common problem that many social workers have to handle frequently. The definition of this phenomenon is ambiguous and social secretaries have to learn how to handle these types of situations. This bachelor thesis will focus on how they perceive this and how they cope with it, as well as the consequences of their perceptions and coping strategies. To answer th

Ur ett demokratiskt perspektiv är muntlig framställning viktigt eftersom förmågan att göra sin röst hörd är såväl en rättighet som en skyldighet i ett demokratiskt samhälle. Dessutom är muntlig framställning ett krav för att elever i gymnasiet ska bli godkända i svenska. Att talrädsla är vanligt förekommande bland gymnasielever är således problematiskt. Syftet med denna studie var att undersöka läTranslated title: “Many students find it difficult even if they do not suffer from speech anxiety”: An interview study on teachers’ perspectives on upper secondary school students’ speech anxiety and on oral presentations in relation to the democratic mission From a democratic perspective, oral proficiency is important since the ability to make one’s voice heard is a right as well as a responsibi

The main goal of the Paris agreement is to hold global warming below 2 degrees Celsius. A goal which requires a rapid peak and decline of global emissions. With the adoption of the Paris agreement, countries submitted Nationally Determined Contributions making national climate legislation a key tool for how to reach the goal. While the response so far has failed to reduce global emissions, climate

A growing population with increasing life expectancy means that the proportion of cognitively ill people is increasing. This puts pressure on the home care service due to lack of time and resources, which leads to a decline in the well-being and quality of life of care recipients. A consequence of cognitive illness is memory loss, which leads to everyday chores such as toothbrushing often being fo

The aim of this study is to analyze how professionals in swedish substance abuse care relate to gender and sexuality in their work.

The empirical material consists of six semi-structured interviews with professionals of health and rehabilitation clinics

Swedish social workers are generalists and on the broad field of work are often employed with different titles. The profession of social workers is therefore considerably difficult to define. What does this mean for the social workers’ professional identity at large? The aim of this study was to give account to how newly graduated social workers experience and reason about their professional ident

Jus cogens norms and obligations erga omnes are concepts within international law that are often used to reinforce legal claims. This thesis aims to assess to what extent invoking these concepts, along with their reinforcing capabilities, is justified in specific cases. In order to achieve this, the thesis first gives an overview of the theoretical debate surrounding the concepts of jus cogens no

To meet the growing demand of meat alternatives, this project was dedicated to creating a chicken analogue prototype with mycoprotein. Within the project, two approaches of alginate gelation, external (diffusion) crosslinking and internal crosslinking, were studied in this particular food matrix. Using the external crosslinking method, the effects of major ingredients on the texture, structure and

Hur kan restmaterial från stålindustrin användas för att minska uttaget av naturresurser? Ett vanligt användningsområde av exempelvis stålslagg är som konstruktionsmaterial vid sluttäckning av deponier. Genom att använda slagg för detta ändamål kan mängden deponerat material minska, samtidigt som man kraftigt minskar behovet av vanligt täckmaterial, såsom grus och jord. Stålslagg kan även användasA variety of excess material is produced in the processes used in the scrap-metal based steel industry. The largest stream of material, by volume, is steel slag. Since slag material has very different properties and wide differences in its chemical composition its usage can be found in different sectors. The increased understanding of slag and its properties has made companies less prone to divert

Black Carbon är resultatet av ofullständig förbränning av fossila bränslen och biomassa. Partiklarna blir luftburna i samband med förbränning och sprids över hela jorden. Utsläpp och spridning av BC är problematiskt, eftersom partiklarna har stor påverkan på människors hälsa och miljön. Metoder för utvinning och kvantifiering av BC ur olika material finns. I studien används en variant av CTO-375-mBlack Carbon is the product of incomplete combustion of fossil fuels and biomass. The particles become airborne during combustion and are effectively distributed all around the world. The release and distribution of BC is of concern because of the effect it has on our health and the environment. To be able to separate BC from sediment and quantify the amount, different methods have been developed.
