This thesis presents two sources of extreme ultraviolet (XUV) radiation based on high-order harmonic generation (HHG) in gases. The sources were developed for experiments requiring high-flux harmonic beams or HHG pulses at high-repetition rate. These were used experimentally to image nano-scale objects. The high-flux HHG source was used for digital in-line holography, and the high-repetition rate
The objective was to investigate the relation between serum levels of interferon-alpha (IFN-alpha), the activity of an endogenous IFN-alpha inducing factor (SLE-IIF), clinical and immunological disease activity as well as serum levels of antiretroviral antibodies in SLE. Serum levels of IFN-alpha were measured in serial sera from 30 patients sampled at different stages of disease activity (SLEDAI
The chronic active inflammation caused by Helicobacter pylori is dominated by neutrophils, macrophages, lymphocytes and plasma cells. Several interleukins are involved in the inflammatory process. The aim of this study was to investigate the effect of astaxanthin on gastric inflammation in patients with functional dyspepsia. Forty-four consecutive patients were included, and biopsies were examined
Direct numerical simulations (DNS) of low and high Karlovitz number (Ka) flames are analysed to investigate the behaviour of the reactive scalar sub-grid scale (SGS) variance in premixed combustion under a wide range of combustion conditions (regimes). An order of magnitude analysis is performed to assess the importance of various terms in the variance evolution equation and the analysis is valida
The home has a self-evident place within audience studies. In spite of this salient position, the home has seldom been theoretically problematized; it has often been ‘reduced’ to a social context of the prioritized media engagement (domestication research is partly an exception). The paper is further justified by the fact that media and media practices are important for the home and its boundaries
Background:For software-intensive organizations, Open Source Software (OSS) may provide a pivotal building block in business models and strategies, product and service offerings, as well as in tool and infrastructure setups. The Requirements Engineering (RE) and development processes of OSS take place inside communities where the focal organization is a stakeholder among many, including competitor
The accumulation of Cr(VI)will cause mutagenic and carcinogenic effects on humans. Therefore, the standard regulations have been governed by the EPA to control the chromium content in the effluent and drinking water and have made it mandatory [1]. For the better recovery of the adsorbent; Magnetic nano particle based phosphorene titanium na
A search for the decay of the Standard Model Higgs boson into a bb pair when produced in association with a W or Z boson is performed with the ATLAS detector. The analysed data, corresponding to an integrated luminosity of 36.1 fb-1, were collected in proton-proton collisions in Run 2 of the Large Hadron Collider at a centre-of-mass energy of 13TeV. Final states containing zero, one and two charge
The creation of an efficient public transport system increasingly requires collaboration between independent organizations. Institutional reforms in Europe have created governance situations where collaboration between organizations is a critical issue, and examples include the integration of transport and land-use planning and the planning of large public transport projects. The organizational co
In Activity Based Working Environment (ABWE) offices, employees are allowed increased autonomy and are expected to choose where, when, with whom, and to some degree with what, to work; in other words, employees are expected to self-lead to a higher degree and to coordinateand align with colleagues. Effectsof these expectations on employees’cogniti
This licentiate thesis is in the field of biomedical signal processing with main focus on processing of cardiac signals measured on the body surface or invasively from patients with atrial fibrillation (AF). The first part addresses spatial analysis of AF using VCG data synthesized from the 12-lead ECG. Two parameters each are extracted to characterize the spatial orientation as well as the spatia
Transmission problems and domain decompositions for non-autonomous parabolic equations on evolving domains Amal Alphonse, Ana Djurdjevac, Emil Engström, and Eskil Hansen Abstract. Parabolic equations on evolving domains model a multitude of applications including various industrial processes such as the molding of heated materials. Such equations are numerically challenging as they require large-s

This thesis explores the potential for collaboration between architecture students and children in the creative process of architectural design, emphasizing how such partnerships can transform spaces and enrich the built environment. Drawing on research that explores interactions between architecture students and children, as well as by connecting my own memories of this area with those of the chi
Even though the first coronavirus pandemic was registered in 1965, SARS-CoV-2 was better acknowledged when it caused the worldwide pandemic in 2019 in which millions of individuals lost their lives. Due to its facile way of spreading from one individual to another, the number of infected cases has gone up to more than 750 million to this day. DENV is a very dangerous virus due to its asymptomatic
Den 22 juli 2022 infördes ett kronvittnessystem med syfte att öka lagföringen och bryta den rådande tystnadskulturen. Ett system som innefattar en strafflindringsgrund avseende medverkan till utredning av annans brottslighet. Tanken bakom kronvittnessystemet är att öka incitamenten för miss-tänkta att samarbeta för att fler allvarliga och svårutredda brott ska klaras upp. Syftet med uppsatsen är On July 22, 2022, a crown witness system was introduced with the aim of increasing prosecution rates and breaking the prevailing culture of silence. This system includes a basis for sentence reduction regarding participation in the investigation of another's criminal activity. The idea behind the crown witness system is to increase incentives for suspects to cooperate in order to solve more se
The ever evolving automotive industry is pushing for further electrification of the vehicle fleet and the need for new electric drivetrains is therefore in high demand. The Formula Student competitions have also shifted their focus towards electric vehicles where innovative and efficient drivetrains are premiered in the design events. This master thesis work aimed to continue the development of Lu

The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. Firstly, a custom-made flavor was created for the experiments covering as much as possible a broad area of compounds prec
Physics-informed neural networks integrate physical laws into machine learning models to solve differential equations. This thesis investigates an inverse physics-informed neural network framework for estimating viscosity in Tetra Pak’s injection molding process, where direct measurements are not possible. By enforcing the Navier-Stokes equations and using sparse velocity and pressure data, a virt
