The event generator PYTHIA can be used to simulate the hadronic part of cosmic particle showers in the atmosphere. Until now, the collision between particles and atmospheric nuclei has been modeled in a simplified way by the PythiaCascade add-on, approximating the nuclear effects. However, at present it is possible to include the Angantyr module, which constructed a detailed description of the nuc
Traditionally, radio communication research has focused on improving range and data transmission rates. Over the past decade, there has been a growing demand for small devices that should be able to interact with each other, and to facilitate this growth, low-cost and low-power radios are necessary to ensure devices are able to function for extended periods of time without maintenance. This thesis
This thesis investigates the European Union’s Carbon Border Adjustment Mechanism (CBAM) as a novel intersection between climate regulation and international trade law. It explores the extent to which CBAM serves as a legitimate environmental measure under EU and World Trade Organization (WTO) legal frameworks or whether it risks functioning as a de facto instrument of protectionism. This is partic
A biographical ideology-analysis of Sven Arvid Flory’s diaries, 1932‒1941. This study follows the diaries of the Swedish officer Sven Arvid Flory from 1932 through 1941, analysing the political and personal notes made and relating them to broader frameworks of ideology. First impressions of the material hinted at nazi sympathies. The study then focused on these ideological aspects of the diaries,
This thesis investigates the structural, social, and spatial factors shaping women’s spatial mobility in Gothenburg, Sweden. Employing a quantitative approach grounded in relational spatial theory, the developed method combines quantitative regression analysis with a case study on two neighbourhoods to examine how gender inequalities, domestic responsibilities, labour force participation, and ethn
The growing demand for sustainable and functional plant-based protein sources has positioned yellow pea (Pisum sativum) as a promising candidate in the development of next-generation food products. From a sustainability perspective, yellow pea fermentation represents an environmentally favorable protein source compared to animal derived alternatives. The nitrogen fixing capacity of yellow pea furt
Current trends in hardware design have led to a growing interest in parallel-in-time (PinT) methods for increasing parallelism in numerical solvers for partial differential equations (PDEs). In this thesis, we consider the Multigrid Reduction in Time (MGRIT) algorithm (Falgout et al.) for linear parabolic PDEs. We provide a description of the algorithm, as well as a derivation of the error propaga
Purpose: The purpose of this thesis is to investigate the effects of the announcement and implementation of the EU’s Corporate Sustainability Reporting Directive (CSRD) on ESG scores and individual pillar scores of firms. Furthermore, this thesis investigates the impact of firm ESG scores on firm performance. Methodology: This thesis uses Difference-in-Differences and Regression Discontinuity De
This study investigated the influence of various native and modified starches on the quality and staling behaviour of gluten-free bread. Four starch types: native wheat starch, cross-linked tapioca starch, fractionated native potato starch (FPS), and acetylated potato starch (Amylacetate) were evaluated by incorporating them into a standardized gluten-free bread formulation as the main starch sour
The transition to renewable energy is a critical element in global efforts to combat climate change. This study explores the decarbonization pathway for Peru’s energy sector, emphasizing renewable energy integration in the electricity generation sector. Peru's rich renewable resources—hydropower, wind, solar, geothermal and biomass—highlight its potential as a regional leader in sustainable en
In this thesis, initiated by Axis Communications, the material choice of a folded horn loudspeaker was investigated. The main goal of the project was to determine if it was possible to reduce the costs and environmental impact of the product by means of optimizing the material, while maintaining or improving its performance. The three main parameters which were analyzed were the acoustic performan
This thesis presents a way of representing electric and magnetic fields directly as linear combinations of products of components of Weyl spinors, without using a four-potential. First it is shown that when Lorentz transforming the spinors, these fields transform according to the tensor transformation of the electromagnetic fields. Then, by explicitly expressing the spinors in terms of a four-mome
This paper explores the Klein-Gordon equation, a relativistic wave equation. More specifically, it studies the free form of the equation, where the potential is set to zero. The partial differential equation, together with initial conditions, forms an initial value problem. The first goal of the paper is to derive the Green's function for the problem. This is done in several ways, using spectr
This thesis investigates what drives people to use credit-style Buy Now, Pay Later (BNPL) services, focusing on Klarna users in Sweden. Drawing on behavioral economics, it tests whether having a present-biased time preference (a strong preference for immediate rewards) can predict a person’s use of Klarna’s “Pay Later” and “Installments” features. To explore this, a cross-sectional survey (N =100)
This thesis examines the role of visual media in conveying the Gallic founding myth and constructing national identity in nineteenth-century France. Positioned at the interdisciplinary intersection of nationalism studies and memory research, it investigates how visual representations embed the Gallic founding narrative – despite its association with military defeat – into France’s collective memor
Studien syftar till att kartlägga entreprenörers anbudsprioritering och ge offentliga beställare kunskap om marknaden för att kunna anpassa sina förfrågningsunderlag. Studien har genomförts som en kvalitativ studie innehållande litteraturstudie, dokumentstudie och intervjustudie. Tre administrativa föreskrifter, AF-delar, har analyserats i dokumentstudien. I intervjustudien har både entreprenad-fThe study aims to map contractors’ bid prioritization and provide public clients with knowledge about the market to be able to adjust their tender documents. The study was conducted as a qualitative study including a literature review, document study, and an interview study. Contractual tender documents were analyzed in the document study. In the interview study, both contractors and public procu
Bakgrund: Antalet människor som på olika sätt påverkas av naturkatastrofer, krig eller konflikter ökar. Dessa katastrofsituationer medför att de som drabbas får inskränkt möjlighet att engagera sig i viktiga och meningsfulla aktiviteter. Arbetsterapeuter har kompetens om hur person, miljö och aktivitet samspelar och kan bidra till arbetet i samband med katastrofsituationer och med katastrofdrabbadBackground: The number of people affected by natural disasters, war, or conflicts is increasing. These disaster situations limit the ability of those affected to engage in important and meaningful activities. Occupational therapists have expertise in how person, environment, and activity interact and can contribute to efforts related to disaster situations and people affected by them. Aim: The aim
Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals widely used in consumer and industrial products. Increasing evidence of their adverse health effects has intensified the need to understand their impact on human immune function. This study assessed PFAS toxicity using a human dendritic cell model by focusing on gene expression and surface marker modulation, as well as a
The Arctic has increasingly emerged as a geopolitical horizon shaped by environmental, security and economic transformations. As sea ice melts and military and commercial interests materialise, questions arise about how the region is discursively constructed by various stakeholders. With the Arctic Council in flux, alternative forums have gained significance as sites for dialogue and public diplom
