The rising levels of greenhouse gas emissions, especially of carbon dioxide, imposes a significant threat to the world, requiring new decarbonisation technologies. This thesis explores integrating a Power to X system with an existing biogas plant utilizing waste from salmon fishery. Three pathways for upgrading biogas to methanol or methane were investigated: (P1) direct carbon dioxide to methanol

Sannolikheten att det finns en högtalare nära dig är hög. De finns där för att spela musik i en affär, för att meddela att brandlarmet har gått i byggnaden du befinner dig i eller för att berätta att tåget du ska åka med är inställt. Alla högtalare låter på lite olika sätt, de har sina egna skavanker som gör att en viss frekvens kanske låter lite mer än andra. I detta projekt har vi funderat på deThis thesis investigates the performance and feasibility of passive and active analog frequency compensation filters for audio signal processing in a distributed speaker system. One passive and one active circuit topology were investigated more thoroughly and then the active filter was realized on a PCB and evaluated with electrical, thermal and acoustic measurements. The work also resulted in tw

The Traditional Knowledge (TK) of Indigenous Peoples and Local Communities (IPLC) plays a crucial role in addressing the biodiversity and climate crises. Yet, market- and state-driven governance of TK continues to assist and enables its exploitation. I investigate the potential of Traditional Knowledge Commons to protect the knowledge and rights of IPLC from violations. Through a multi-case study

The Philippines, the most disaster-prone country globally, faces intensified natural hazards due to climate change. Informal settler families, living in precarious conditions, are particularly vulnerable. This study investigates the resilience of an informal settler community in Tondo, Manila, assessing their capacities to cope, adapt, and transform in the face of disasters, particularly typhoons

The exclusive economic right of communication to the public granted to authors in respect of their works, as enshrined in Article 3(1) of the Information Society Directive 2001/29/EC, has been the focal point of extensive litigation, surpassing any other provision within European Union (EU) copyright legislation. Undertaking legal dogmatic research, this thesis seeks to delineate the scope of Arti

Marine coatings used on merchant ships have recently emerged as a source of microplastics in marine environments. Marine coatings encompass all paints and coatings applied to various parts of a ship, primarily for anti-corrosion, antifouling anti-skid, heat-resistance, and cosmetic enhancement. However, marine coatings on merchant ships have evaded classification and were not included in the micro

Title: Women experiencing the second stage of labour for the first time: a qualitative free-text analysis within the Oneplus trial. Background: The second stage of labour is the time from full cervical dilation to the birth of the baby. The risks to the woman and the baby are increased during this stage, leading to intensified midwifery care. A positive birth experience is a significant goal of in

Many preschoolers in Sweden have other family languages than Swedish. Sign-supported speech (SSS) is often used to support children's second language development and participation in interaction. The aim of the present paper is to study how preschool teachers use SSS in interaction with multilingual children, and children's way of participation in such interaction. The study was conducted in three

Medical image segmentation is a critical component in a wide range of clinical applications, enabling the identification and delineation of anatomical structures. This study focuses on segmentation of anatomical structures for 3D printing, virtual surgery planning, and advanced visualization such as virtual or augmented reality. Manual segmentation methods are labor-intensive and can be subjective

Climate change poses a significant global challenge, profoundly affecting species distribution. In recent years, research focusing on the impacts of climate change on freshwater taxa has been relatively limited compared to studies on terrestrial taxa. This study seeks to identify hotspots and occurrences of all Carasobarbus freshwater fish species while also predicting the potential implications o

The Natural Resources Conservation Service Curve Number method (NRCS-CN) is the most widely used approach to estimate runoff from rainfall events. However, some uncertainties in the method remain linked to the value of the standard initial abstraction ratio (λ) and discrepancies between computed and standard tabulated Curve Number (CN) values. Here, we compute CN values and investigate the effects

Background: Observational data on composite scores often comes with missing component information. When a complete-case (CC) analysis of composite scores is unbiased, preferable approaches of dealing with missing component information should also be unbiased and provide a more precise estimate. We assessed the performance of several methods compared to CC analysis in estimating the means of common

We devise an autonomous quantum thermal machine consisting of three pairwise-interacting qubits, two of which are locally coupled to thermal reservoirs. The machine operates autonomously, as it requires no time-coherent control, external driving or quantum bath engineering, and is instead propelled by a chemical potential bias. Under ideal conditions, we show that this out-of-equilibrium system ca

Substance P, previously dismissed as a therapeutic target for migraine due to the failure of neurokinin-1 receptor antagonists, warrants renewed attention. Building on the success of therapies targeting the calcitonin gene-related peptide (CGRP) system and pituitary adenylate cyclase-activating peptide (PACAP) in migraine prevention, which highlight the importance of targeting peptides, this propo

Lipoproteins, key mediators of lipid transport, facilitate the bidirectional transfer of lipids such as fatty acids, triglycerides, and cholesterol between soluble particles and cell membranes. High-density lipoproteins (HDL) primarily engage in reverse cholesterol transport, while low-density lipoproteins (LDL) predominantly deposit lipids, affecting cardiovascular health with a well-known role i

Background: Cortical atrophy is a common manifestation in behavioral variant frontotemporal degeneration (bvFTD), exhibiting spatial heterogeneity across various genetic subgroups, which may be driven by distinct biological mechanisms. Methods: We employed an integrative imaging transcriptomics approach to identify both disparate and shared transcriptomic signatures associated with cortical thickn

The identity and source of flexible, semi-transparent, vascular-like components recovered from non-avian dinosaur bone are debated, because: (1) such preservation is not predicted by degradation models; (2) taphonomic mechanisms for this type of preservation are not well defined; and (3) although support for molecular endogeneity has been demonstrated in select specimens, comparable data are lacki

Bygg- och anläggningsindustrin har en betydande påverkan på Sveriges totala koldioxidutsläpp. För att uppnå FN:s globala mål krävs tydliga förändringar. Broar som byggs idag kräver mer material än broar som byggdes för 50 år sedan, trots att brotyperna är likadana. Tvärkraftsarmering i form av skjuvbyglar är något som konstruktörer generellt sett strävar efter att minimera av miljömässiga, arbetsmThe national construction and civil engineering industry contributes significantly to Sweden’s total carbon dioxide emissions. Meeting the United Nations’ global sustainability goals will require intelligible, measurable and structural changes within the industry. Notably, modern bridge designs often demand greater material use than those built half a century ago, albeit the structural types are f

As demand for nicotine pouches continues to grow globally, especially in the form of tobacco-free snus, efficient and scalable packaging solutions have become essential for producers. This report presents the design, development, and testing of a fully automated end-of-line packaging station using a collaborative robot (cobot), specifically the UR10e. The project was carried out in collaboration w

Foreign Object Debris (FOD) poses a serious threat to airport safety and efficiency, yet current detection processes often rely on manual labor, it is a repetitive task that is prone to human errors. This thesis investigates how a Human-Machine Interface (HMI) can be deigned to support the FOD detection and handling, with a specific focus on the needs and workflows of ground personnel in apron ope
