Aortic valve stenosis is a common congenital heart defect among children. In affected patients, the normal tricuspid valve structure is malformed into a bicuspid valve structure due to a fusion at one commissure. A common treatment is transcatheter balloon valvuloplasty, where a balloon is inserted through the aortic valve and inflated to mechanically tear the fused region, restoring a tricuspid s
How can we understand Gällivare municipality as a sacrifice zone through local narratives of green transition? The transition to low-carbon economies in the wake of the European Green Deal drives increased demands for metals and minerals, renewable energy, biomass from forests – intensifying green extractivism. In Gällivare municipality, located in the rural north of Sweden and within the borders
Introduction Illicit maritime activities frequently involve "dark" vessels that disable or manipulate their Automatic Identification System (AIS) signals to evade detection. This study evaluates the effectiveness of Synthetic Aperture Radar (SAR) and Optical imagery for vessel detection using both “manual” and automated Deep Learning (DL) methods while integrating AIS data to validate, i
Received Signal Strength Indicator (RSSI) circuits are critical in modern Wi-Fi receivers, playing a key role in power management and protecting the radio frequency (RF) front-end from saturation and potential damage. This thesis presents the design and evaluation of a novel rectifier circuit conceptualized for use in an RSSI system within an industry-standard 22nm CMOS node, specifically targetin
This essay explores the obligation to redeploy as a result of redundancy, conducting a comparative analysis of the redeployment processes in Sweden and Germany. The purpose of the essay is to examine what constitutes a reasonable redeployment in each country and identify differences and similarities in their respective legislation. This is achieved by using the legal dogmatic method, as the study
Cerebral palsy is an umbrella term for a group of neurological disorders, affecting motor function, movement and posture. Contractures, restrictions in the range of motion of joints, are a common problem affecting people living with cerebral palsy. In the present thesis, the effect of having a contracture on one knee, on the hazard for developing a contracture on the other knee, is explored. This
Fermentation has played a vital role in human history, offering solutions for food preservation, culinary diversity, and the creation of diverse and flavorful foods and beverages. Its importance continues today, both in traditional practices and in modern industrial applications. This report outlines the outcomes of an investigation into and the optimization of the solid-state fermentation proces
Urban climate neutrality has emerged as a critical goal for sustainable urban development, with the European Union’s Cities Mission aiming to achieve 100 climate-neutral and smart cities by 2030. However, the term “climate neutrality” holds diverse interpretations among stakeholders, leading to inconsistencies and potential negative outcomes. This study investigates the dominant sociotechnical ima
Swedish Title: En Ny Era för Ett Nytt Burma: Avkoloniseringens Diskurs och Nationens Strävan i Burma efter Andra Världskriget This study explores the nature of the nationalist discourse in Burma (Myanmar) in the short period of time following World War II but preceding Burma’s declaration of independence on the 4th of January, 1948. Burma, then a British colony in Southeast Asia, had been promised

Vessel-source pollution is regarded as one of the major sources that harm marine environment. It has become an issue of public concern since 20th century due to a series of oil pollution incidents on the sea. Fortunately, international law has been developed to control this source of pollution taking consideration of the importance of protection and preservation of marine environment and sustainab
This thesis has investigated the prevailing understanding of poor leadership as a major impediment to the democratization of the Democratic Republic of Congo. Analytical studies found evidences on the correlation between the authoritarian regimes installed in the Democratic Republic of Congo and the abortive process of democratization under the leadership of Mobutu Sese Seko and Laurent-Désiré Kab
Tri-isopropylsilyl thio-glycosides (TIPS S-glycosides) were synthesized through base promoted SN2 substitution of glycosyl halides with TIPS-SH or by Lewis acid promoted glycosylation of TIPS-SH with glycosyl acetates or p-methoxyphenyl glycosides. Various thioglycoside derivatives were obtained in high yields by one-pot fluoride-mediated de-silylation and thiol alkylation with alkyl halides or Mi
In this study, different flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenases (FADGDHs) were characterized electrochemically after "wiring" them with an osmium redox polymer [Os(4,4'-dimethyl-2,2'-bipyridine)(2)(PVI)(10)Cl](+) on graphite electrodes. One tested FADGDH was that recently discovered in Glomerella cingulata (GcGDH), another was the recombinant form expressed in Pichia pa
With diversified requirements and varying manufacturing environments, the optimal production planning for a steelmill becomes more flexible and complicated. The flexibility provides operators with auxiliary requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is proposed for the optimal planning that incorporates v
An efficient protocol has been developed for the exo-mono and exo,exo-bis functionalization of Tröger's base in the benzylic 6 and 12 positions of the diazocine ring. The lithiation of Tröger's base using s-BuLi/TMEDA followed by electrophilic quench affords exo-mono- and exo,exo-bis-substituted derivatives of Tröger's base in good to excellent yields. The variation of the number of equivalents of
When flying through narrow spaces, insects control their position by balancing the magnitude of apparent image motion (optic flow) experienced in each eye and their speed by holding this value about a desired set-point. Previously, it has been shown that when bumblebees encounter sudden changes in the proximity to nearby surfaces - as indicated by a change in the magnitude of optic flow on each si
