This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes
Motivated by the rising importance of today’s environmental issues and more specifically the role of energy conservation policies, the current study investigates the Granger causal relationship between energy consumption and economic growth in eight European countries. Using a large dataset that overall spans from 1800-2009 the study employs the Toda-Yamamoto procedure and cointegration analysis w
Gender equality (GE) is one of Sweden’s three thematic prioritizations in foreign aid and have so been since 2007. Gender equality is emphasized as important for development and as a question in which Sweden has added value in promoting. The thesis examines what type of gender equality Sweden promotes in development cooperation with nine African countries and how it has changed in the country and
This study investigates volatility spillover between the prices of electricity at Nord Pool, carbon emission allowances in the EU Emissions Trading System (EU ETS) and tradable green certificates (TGC) in the Swedish-Norwegian TGC market. ETS and TGC schemes are market-based policies with the overlapping goals of mitigating greenhouse gas emissions and stimulating sustainable energy investments. A
This essay is about universalism in the welfare state of Sweden. The essay contains an evaluation regarding one of the social insurances which is the pension system. This paper analyzes how universalism has changed in the transition from old to the new Swedish elderly pension system. During the 1990s a new pension system was introduced which is why an evaluation is of interest. Through theories ab
In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase
Heterologous overexpression of proteins signifies that the encoding gene of a protein in one organism is expressed in another host organism that normally does not have that gene in its genome. In basic biochemical research, this is an important method for studying various protein functions such as activity and interactions in biological processes, as well as obtaining sufficient amounts to determi
Background The two main functional goals of postural control are postural stability (balance) and postural orientation. Postural orientation is the ability to maintain alignment between body segments and the environment during a static or dynamic activity. Nae et al. have evaluated the measurement properties of a clinical test battery for assessing postural orientation errors (POEs) in patients wi
Climate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers. Small streams are the
Reaching consensus about sexual and reproductive health and rights (SRHR) has never been easy on the international arena. The United Nations Population Fund and several women rights movements across the world are the leading actors in promoting SRHR. At the same time as progress for world with a universal implementation is being made, oppositional forces against SRHR are on the rise. The focus of
Background: Rare variants of the triggering receptor expressed on myeloid cell 2 (TREM2) gene are strong risk factors for Alzheimer’s disease (AD), and drugs targeting the TREM2 protein are being developed. However, it is unknown what the effect of TREM2 variants is on the AD phenotype. Methods: Here we studied a full range of clinical and biomarker measures in a large cohort of TREM2 variant carr
Contemporary welfare policies often frame the unemployed as ”job seekers”, a position which demands that the individual engages in active job seeking, continuous self-work and various employability-enhancing activities. This article examines how the unemployed, through digital job coaching webinars by Arbetsförmedlingen (the Swedish Public Employment Service), are positioned and steered as job seeContemporary welfare policies often frame the unemployed as ”job seekers”, a position which demands that the individual engages in active job seeking, continuous self-work and various employability-enhancing activities.

BACKGROUND: Medical students navigate a complex landscape of digital tools with potential to enhance learning. The main objectives of the current study were to investigate which digital resources are being used, which background factors are associated with utilization, perceived advantages and disadvantages of different digital resources, and explore future directions.METHODS: Cross-sectional, nat
Objective: To analyze the outcomes of urgent/emergent endovascular aortic repair of patients with free/contained ruptured thoracoabdominal aortic aneurysms (rTAAA). Background: Endovascular repair of rTAAA has been scarcely described in emergent setting. Methods: An international multicenter retrospective observational study (ClinicalTrials.govID:NCT05956873) from January 2015 to January 2023 in 6
Background: Keeping the umbilical cord intact the first minutes after delivery is beneficial for both term and preterm infants. However, this may be challenging in caesarean sections (CS) due to lack of mobile resuscitation equipment, maintenance of sterility or concern for excessive maternal blood loss. The objective of this study was to develop and pilot-test extra-uterine placental transfusion
Background: MR-generated acoustic noise may be particularly concerning at 7-Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized. Purpose: To evaluate image quality, sound pressure levels (SPLs), and perceived noi
We assessed hepatocellular carcinoma (HCC) risk associated with smoking and alcohol consumption and their interactions, using both questionnaire data and objective serum biomarkers. Information on smoking and alcohol consumption was collected at baseline from 450,112 participants of the EPIC cohort, among whom 255 developed HCC after a median follow-up of 14 years. In a nested case–control subset
Background: Opioid use disorder is a chronic disorder with a high risk of overdose-related morbidity and mortality where a large proportion of these can be averted by timely administration of the antidote naloxone. For naloxone to be present when and where overdoses occur, broad-scale overdose education and naloxone distribution (OEND) must be established. A regional naloxone program was implement
