To address the pressing challenge of decarbonizing heavy-duty transportation, this thesis explores advanced combustion strategies using sustainable gaseous fuels, specifically hydrogen and methane, in internal combustion engines (ICEs). While electrification remains difficult to implement in long-haul applications due to energy density and infrastructure limitations, this work identifies and refin

In the plant-based beverage industry, a residue called okara, is generated in large quantities in the liquid-solid separation step. Despite the high nutritional value of okara from soy and oat beverages with respect to fiber and protein content, these residues are generally discarded or used as animal feed or compost. It would be more sustainable to utilize okara for human consumption, however, th

Non-typeable Haemophilus influenzae (NTHi) is an emerging respiratory pathogen that causes a significant disease burden worldwide, yet an effective vaccine is still lacking. The focus of this thesis is to elucidate the critical molecular interactions governing NTHi pathogenesis and host immunity. We identified Elongation Factor Tu (EF-Tu) as a surface-exposed protein on NTHi, demonstrating its imm

For the past decade, the sharing economy has not only grown but also expanded to cover a wide variety of different activities across the globe. Despite a lot of research, there is still no agreement on how to define and measure the sharing economy, and no consensus on whether the sharing economy is a part of or an alternative to a regular capitalist economy. This paper contributes by presenting a

This master’s thesis project explores different methods for determining an effective electron-electron interaction strength to model dynamic interactions in the Anderson impurity model, an important model within the field of many-body quantum mechanics. The Anderson model describes an impurity atom which is embedded in a metal, with which in can exchange electrons. In this project, different obser

This chapter discusses the role of placed-based relational entanglements in disasters and argues that relations play an important part in shaping how disasters unfold. Exploring the case of mining induced displacement in Sweden’s Malmfälten region – where two cities, Kiruna and Malmberget, and several villages are being moved or razed to make way for expanding mines – the chapter demonstrates how This chapter explores the role of placed-based relational entanglements in disasters and argues that relations play an important part in shaping how disasters unfold.

Since the 1987 UN report “Our Common Future”, aimed at bridging divides among various stakeholders by advocating for “sustainable development”, renewed demands for environmentally adjusted measures have emerged, calling for a future that consolidates socially just, ecologically sound, and economically viable outcomes through sustainable forest management. For Nordic forests, this means policy meas

The atomic structure of catalytic surfaces and its relation to function is important for the understanding and development of industrial catalysts. However, many surface sensitive methods are limited to low-pressure environments, creating a gap between experimental results and reality, and it is not certain that the findings can be applied to the real system. Surface X-ray diffraction is a method

Background, Motivation, and ObjectiveThe demand for tissue-mimicking materials (TMMs) is increasing alongside the advancement of hybrid imaging such as photoacoustic imaging (PAI). Developing suitable TMMs for PAI is challenging due to the need to mimic both optical and acoustic tissue properties. The TMMs with tunable properties are needed for the calibration of these imaging modalities, as well

A central feature of internalizing mental disorders, such as obsessive-compulsive disorder (OCD) and anxiety disorders, is the avoidance of rewarding situations to prevent the risk of experiencing distressing emotions. Previous research has shown that obsessive and anxious individuals avoid situations where rewards come at the cost of aversive experiences, a phenomenon termed costly avoidance.

This study looks at the expectations of young adults in Sweden regarding parental leave and work after having a child. It explores how men and women perceive their roles and responsibilities as parents. The main research question is: “What expectations do young adults have about parental leave and work hours after having children?” Sub-questions include their personal expectations and their views

This study aims to investigate the microeconomic and behavioral economic factors that can explain the rise of the sport padel in Sweden and the following potential over establishment of padel facilities. The study uses a mix of a qualitative and quantitative methodology, including semi-structured interviews and data from 2014-2023. The study seeks to provide insights to deepen the understanding of
