The debate on Nordic defense cooperation has surged in the recent year as a result from a perceived shift in the security environment. The study focuses on the five Nordic states; all of them committed to different security communities and yet engaged in cooperative measures with each other. With the question of exploring the prerequisites for a possible deepening of the Nordic defense cooperatio
The last decades the modern sporthorse have changed a lot, both physically and in temperament. Horses have gotten more athletic, sensitive and faster. Selective breeding, new science findings and more competition, in combination with a role change from workhorse to sporthorse have made this change possible. The idea to investigate and develop horse equipment was initialised during meetings with th
This thesis discusses whether Corporate Social Responsibility (CSR) can affect a company’s, and consequently a portfolio’s, stock market performance. The study presupposes the regular assumptions drawn from CAPM. By creating three different portfolios, consisting of companies with similar financial characteristics, but with different levels of CSR-involvement, we investigate how the CSR-factor may
Interest in biofuel use is growing in aviation, due to its potential for lower GHG lifecycle emissions and as a possible price competitive alternative to fossil fuels in the long-term (ATAG, 2012). While the use of biofuels in aviation is a new phenomenon, compared to the automotive industry, several actors from the industry and governments have been involved in various initiatives to research, te
Hydropower in Brazil stands for 64.5% of all energy sources in the country. The largest number of hydropower plants are located in the Paraná basin, which together have an installed capacity of approximately 40 GW including the world’s largest producing hydropower plant, Itaipu. The wet season during Brazilian summer (January-March) is the most important for hydropower. Occasionally, extreme, su
Den offentliga sektorn står inför utmaningar när det kommer till digitalisering och medborgare har höga förväntningar på att den offentliga sektorn ska vara effektiv och erbjuda högkvalitativ service. År 2018 tilldelades den portugisiska kommunen Cascais ett pris från organisationen World Summit Awards för sin digitala plattform City Points Cascais inom kategorin, Digital Innovation in Government The public sector is facing challenges related to digitalization. Modern citizens have expectations that the public sector should be more efficient and provide quality services. In the year of 2018, the municipality of Cascais, Portugal, was awarded the best platform in the category Digital Innovation in Government and Citizen Engagement by the World Summit Awards. The platform is called City Poin
In this thesis I extend the chirality-flow method to the full standard model at tree-level by including massive particles and electroweak interactions. The chirality-flow method is a new diagrammatic method for calculating Feynman diagrams that is based on the spinor-helicity formalism, that before this thesis was written had been worked out for massless QED and QCD at tree-level. I summarize what
To control an accelerating proton beam that travels close to the speed of light, a large number of beam diagnostic instruments are needed. One of the instruments that will be used at the accelerator of the European Spallation Source is a Non-invasive Profile Monitor (NPM). Once installed, this system will measure the transverse beam profile by imaging the fluorescent gas induced by the accelerated

Society faces multiple and interconnected crises that require transformation. Education has long been theorized as key to transformation, yet an important driver of transformation, imagination, is marginalised within pedagogical approaches to sustainability. This thesis examines Beyond the Fossil Era (BFE), a pedagogy that invites learners to become co-creators of a speculative museum looking back
The violation of baryon number, B, is a vital component of a process promoting the excess of matter over antimatter, as it is necessary to explain the baryon imbalance observed in the universe. Since experimental evidence for such an occurrence has yet to be discovered, the HIBEAM-NNBAR experiment, at the European Spallation Source facility, is a proposed two-stage program aimed at expanding the c
The chirality-flow formalism has been proven to simplify the calculation of helicity amplitudes, both analytically and in a first numerical implementation developed as an extension of MadGraph5_aMC@NLO. Expanding on this work, two new implementations have been developed. The first provides an alternative algorithm for the evaluation of diagrams, where helicity amplitudes are obtained by combining
The EU procured for roughly 202000 MEUR (14% of the EU GDP) during 2021 in the public sector. The majority of these contracts are traditional, linear business model purchases. The EU has been developing several strategies, guidelines, and policies for sustainable purchasing, with Circular Public Procurement for a Circular Economy (CE) being one of them, but the implementation rate is low. Electron
In classical eyeblink conditioning a subject learns to blink to a previously neutral stimulus. This conditional response is timed to occur just before an air puff to the eye. The learning is known to depend on the cerebellar cortex where Purkinje cells respond with adaptively timed pauses in their spontaneous firing. The pauses in the inhibitory Purkinje cells cause disinhibition of the cerebellar
This report uses a relational theory of risk within which risk is understood as a relationship between a risk object and an object at risk where the risk object threatens the value embedded in the object at risk. A case study of risk management in railway planning examined through a relational understanding of risk demonstrates how riskwork is conditioned by what is valued, how, and by whom. The r
Cow horn has been a craftig material in Europe for 1000s of years. Yet, in the last 100 years the material has disappeard from our pool of commonly used materials. Today it is mostly used for dogfood and gelatine. I believe that horn could again become a commonly used crafting material, especially for modern and sustainable products. Among my many visions for horn, I see it as a beautiful, natu
Italy is using drones to monitor migrants crossing the Mediterranean Sea. This is partially done through a contract with Leonardo S.p.A – one of the largest arms traders in the world – under which the company undertakes to operate drones in the area on behalf of the state. Meanwhile, Italy has withdrawn its naval assets and is hindering non-governmental organisations from carrying out search-and-r
