Början av 1900-talet såg en oerhörd utveckling av nya forskningsområden inom fysiken. 1905 lade Einstein grunden för den speciella relativitetsteorin, som revolutionerade hur fysiker ser på själva tiden och rummet genom att föreslå att vi kan behandla de båda på samma sätt. Samtidigt växte kvantfysikens värld fram i jakten på en beskrivning av vår verklighets allra minsta beståndsdelar. KvantfysThis thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct produ

Den här studiens syfte var att skapa en bättre förståelse för varför man ska bygga mer med gröna tak samt att göra en jämförelse mellan gröna tak och bjälklag med växtlighet. Vi undersökte även gröna takets nytta som en ekosystemtjänst samt hur nyttan kan ökas. I Sverige har man blivit inspirerad av arkitekten Le Corbusier som utgick från att man kan kompensera minskning av grönt område i stadsmiThe purpose of this study was to create a better understanding of why you should build more with green roofs and to make a comparison between green roofs and floors with vegetation. We also investigated the benefits of green roofs as an ecosystem service and how the benefits can be increased. In Sweden, they have been inspired by the architect Le Corbusier, who assumed that they could compensate

In this work we investigate the hard and soft interactions in the multiple parton interactions (MPI) simulation in Herwig7. The investigation covers how the number of soft and hard interactions in an event is linked to the multiplicity of final state particles. We also present a labeling system for particles produced by different interactions, which we then use to classify the final state particle

Natural resources and their impact on growth has received significant academic attention through the theory of the resource curse. Most literature has studied the relationship between natural resource abundance and economic growth. However, the resource curse argues that development, in general, is negatively affected by resource abundance and that it can be avoided through quality institutions an

The most characteristic clinical symptoms of AD are memory loss and behavioural issues, affecting the daily life of those suffering from AD and their caregivers. Unfortunately, despite extensive researc

The concepts of ‘Old School’ and ‘New School’, peculiar to hip-hop's lexicon, have long been framed by theories of subculture heavily drawing on a binary scale of authenticity and inauthenticity. This dichotomy is widely used to characterize a discursive conflict between the authentic aspects of hip-hop music and its excessively commercialized versions undermining hip-hop’s counter-hegemonic p

Musslor bidrar till en god havsmiljö genom att äta havsplankton och på så sätt minska algblomningen. Idag konsumeras finare musslor av människor i olika rätter, däremot går andrasorteringen ofta till djurfoder eller till gödning. Genom att hitta fler tillämpningar för de proteinrika musslorna skapas en högre efterfrågan på musslor som i sin tur gör att mer musslor odlas och på så sätt ger oss frisMussels contribute to a good marine environment by eating sea plankton and thus reducing the eutrophication. Today, high quality mussels are consumed by humans in different dishes, however, the second quality is often used as animal feed or as fertilizers in agriculture. By finding more applications for the protein rich mussels, a higher demand for mussels is created which in turn means that more

The ongoing Covid-19 pandemic has created a novel and unique situation forcing start-up teams to mandatory-work-from-home (MWFH). With everyday life coming to a halt, start-up teams suddenly adjust their ways of working and transform to virtual means of teamwork performed from home environments. Given the novelty and uniqueness of the situation, MWFH has yet to be academically explored within the
