The reliability of a critical industrial component is decided by the durability of the weakest joint or spot. For applications involving high-temperature operational conditions especially coupled with corrosive environments like fuel cell interconnections, molten metal baths, etc., the joints are the most vulnerable regions for catastrophic failure due to localized material degradation by selectiv
Nanocrystalline AlxCoCrFeNi (x = 0, 0.3, 0.6, 1 mol) high-entropy alloys were synthesized by mechanical alloying (MA) and consolidated by spark plasma sintering (SPS). Single-phase face-centered cubic (FCC) structure was achieved with x = 0 and 0.3. Dual-phase body-centered cubic (BCC)/B2 + FCC structure was obtained in x = 0.6 and 1. Complete solid solution was achieved with a significantly reduc
In the present work, the concept of mechanically activated annealing (MAA) has been applied to produce nanocrystalline Al0.3CoCrFeNi high-entropy alloys (HEAs) with reduced contamination levels. Phase evolution during conventional mechanical alloying (MA), MAA and subsequent consolidation by spark plasma sintering (SPS) have been studied in detail. Complete alloying is obtained after 15 h of MA, w
Research question: How do employees at call centres perceive algorithmic management? Purpose: This study aims to provide insights into how employees in a call centre perceive algorithmic management. Methodology: The study employed a qualitative research method, incorporating interviews with a relativist and social constructionist perspective, to fulfill its purpose and address the research questio
This thesis investigates how Kosovar courts adjudicate rape by qualitatively analysing criminal provisions and court judgements. It aims to contribute to changing ‘the legal story’ of rape in Kosovo so that legal definitions and interpretations better reflect women’s experiences and avoid perpetuating harm to victims. Drawing from a feminist theoretical framework of rape myths and cultural narrati
This thesis investigates how members of the Danish Naturalisation Committee navigate, exer-cise, and justify their discretionary power in exemption cases, and what this reveal about the intersection of law, politics, and affect in the governance of citizenship. While most countries treat naturalisation as an administrative procedure, Denmark stands out: citizenship is granted by parliamentary law,
The AI Commission prescribed a governance model, namely centralized leadership, to tackle existing digitalization challenges, as outlined in the Roadmap for Sweden at the end of 2024. This research discussed the implications of the Roadmap for Sweden on welfare governance within the Automated Decision-making (ADM) context as interpreted through a Weberian theoretical and methodological framework.
Legal abuse is an underrecognized form of domestic violence and coercive control in the legal system, with laws recognizing its proliferation only recently being sparsely enacted. At the same time, the conversation about coercive control as a form of domestic violence has been rising both domestically and internationally. This exploratory, qualitative study endeavors to understand if that rising c
Phase separation arises from the substitution of Y in Zr70-xAl12.5Fe17.5Yx (x = 0–25 at.%) metallic glasses (MGs), resulting in the formation of nano-amorphous domains within a glassy matrix. The glasses with x ≥ 10 show a typical liquid phase separation-induced two-glassy phase (Zr-rich and Y-rich) morphology with droplet-like microstructures (nano-amorphous domains). The size of the domains incr
The picosecond time-domain incoherent singlet excitation transfer and trapping kinetics in core antenna of photosynthetic bacteria are studied in case of low excitation intensities by numerical integration of the appropriate master equation in a wide temperature range of 4–300 K. The essential features of our two-dimensional-lattice model are as follows: Förster excitation transfer theory, spectra
We present a new phase-separated Zr-based metallic glass (MG) composition, free of toxic elements (Ni and Cu) prepared in a glass-forming system by alloying addition. The substitution of Y in Zr70-xAl12.5Fe17.5Yx (x = 0–15 at.%) results in phase separation, giving rise to nano-amorphous domains in a glassy matrix. A homogeneous MG feature is observed for low concentrations of Y up to x = 5. Micros
The excitation annihilation and anisotropy kinetics in the B850 ring were studied. As a result, a new insight into the problem of exciton coherence in photosynthetic light harvesting was obtained.
In the pursuit of sustainable chemical production, feedstock diversification is essential. Lignosulfonates, a water-soluble aromatic byproduct of the sulfite pulping process, offer a green alternative for producing value-added compounds such as vanillin via oxidative depolymerization. However, current depolymerization processes are not comparable due to inconsistencies in feedstocks and a lack of
Background Obesity is increasing among patients with inflammatory bowel disease, but bariatric surgery has been rare in this group owing to concerns about worsening the inflammatory bowel disease. The aim of the study was to evaluate inflammatory bowel disease-related outcomes following bariatric surgery. Methods Nationwide cohort of all adult patients in Sweden between 2007 and 2020 with obesity
Chronic obstructive pulmonary disease (COPD) and asthma both involve inflammation and structural changes in the peripheral airways that are not detectable with current standard tools such as spirometry. Accurate and sensitive assessment of lung function is crucial for early diagnosis, monitoring disease progression, and guiding appropriate treatment.The overall aim of this thesis was to investigat
Objectives: To examine the effects of thiopurine exposure during pregnancy on intrahepatic cholestasis of pregnancy (ICP) in systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD) pregnancies using nationwide data from Swedish healthcare registers. Methods: This register-based cohort study included all singleton pregnancies with prevalent SLE or IBD in Sweden, 2007-2022. Exposure
Introduction: Patients with severe haemophilia A (HA) with no family history of haemophilia will be diagnosed upon their first bleeding event. Methods: Herein, we studied the effects of lack of family history in HA and the subsequent delay of diagnosis on bleeding pattern and early treatment, as well as on the risk of inhibitor development. For this purpose, data on 1237 severe HA patients with kn
Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus. In this work, we are investigating a XOS converting enzyme from the probiotic bacterium Levilactobacillus brevis (formerly Lactobac
Thermal unfolding of whey proteins and whey protein-casein mixtures in simulated milk ultrafiltrate was studied by differential scanning calorimetry. The results are reported as transition enthalpy, temperature of peak maximum, and van’t Hoff enthalpy related to the sharpness of transition. The results of earlier investigations were reviewed. It is suggested that a large part of reported whey
Heat-induced gelation of the bovine whey proteins [serum albumin (BSA), β-lactoglobulin (β-Lg) and α-lactalbumin (α-La)] has been studied individually and in mixture at different conditions by a dynamic rheological method. Values in the shear stiffness modulus (/G*/) appeared on heating at low protein concentration for BSA (∼2%) and at intermediate concentration for β-Lg (∼ 5%). α-La did not form
