Furfural, a renewable platform chemical derived from hemi cellulosic fraction of the lignocellulosic biomass, is a promising precursor for the sustainable production of 2,5- furandicarboxylic acid (FDCA), an important bio-based alternative to terephthalic acid. In this study, we utilized the oxidative capacity of Gluconobacter oxydans to oxidize furfural to 2-furoic acid and employed the UbiD-UbiX
This study examines how the Bird’s Nest in Beijing has been reused after the Olympics and how it is presented as a model of sustainable urban development. Using an Urban Political Ecology (UPE) perspective, it explores how sustainability is defined, implemented, and experienced. The research is based on policy analysis, critical discourse analysis, 20 interviews, and field observation. The finding
Denna studie undersöker hur kvinno-, tjej- och transjourer organiserar och upprätthåller sina verksamheter i relation till statliga bidragssystem, administrativa krav och föreställningar om värde. Studien bygger på kvalitativa semistrukturerade intervjuer med åtta personer verksamma inom olika jourorganisationer i Sverige. Materialet analyserades genom tematisk analys med utgångspunkt i teorier om
Carbon accounting has become an important part of sustainability governance, as organisations are increasingly expected to report and justify their climate impacts. However, emissions figures are not neutral technical outputs. They are shaped by methodological choices, boundaries, assumptions, data infrastructures, and professional judgement. This is especially relevant for municipalities, where c
Infrastructure barriers and high costs of alternative sustainable fuels constrain the global logistics sector's transition to decarbonization. This research investigates how logistics providers establish institutional trust in the 'Book and Claim' service, where the environmental benefits of sustainable fuels are spatially decoupled from the physical transport of goods. Because corpora
Syftet med examensarbetet är att undersöka vilka logistiska utmaningar som uppstår vid återbruksprojekt med mer storskaligt återbruk. Examensarbetet har utförts som en kvalitativ fallstudie där data har samlats in via delvis strukturerade intervjuer, en mindre dokumentstudie samt en jämförelse med ett tidigare forskningsprojekt. Intervjustudien utfördes med sju olika respondenter där fem av dem The purpose with the thesis is to analyse what logistical challenges occur in reuse projects with reuse on a larger scale. The thesis was performed as a qualitative case study where the data was gathered from semi structured interviews, a smaller document study as well as a compression to a research paper. The interview study was performed with seven different respondents where five of them had
On 13 May 2000, a fireworks depot exploded in a residential neighbourhood in Enschede, the Netherlands, killing 23 people and injuring nearly a thousand. Throughout the 1990s, Dutch biopolitical safety campaigns made the individual dangers of fireworks highly visible: the misused firework, the mutilated hand, the personal consequence. The collective risk of a depot in a residential area, by contra
The construction and real estate sector is a major contributor to global carbon emissions and climate change. Ventilation systems, although essential for maintaining indoor air quality and occupant health, account for a significant share of building operational emissions. In HVAC systems, duct layouts significantly influence ventilation impacts through both the embodied carbon from material produc
The application of machine learning in architecture has raised important concerns regarding creativity, authorship, and the usability of AI-generated outputs. An existing limitation is that many generative workflows produce visually compelling images but they remain as visual residue. They may demonstrate rich architectural qualities, but they are detached from the design workflow. This thesis exp
Fennoscandian permafrost peatlands and palsa mires have exhibited pronounced thawing over recent decades, resulting in increased active layer thickness (ALT) and thermokarst formation. Consequently, open water areas have expanded in the well-studied palsa mire Stordalen, located in northernmost Sweden. However, long-term quantifications of open water dynamics remain limited and the relationship be
The continued scaling of complementary metal-oxide semiconductor (CMOS) technology has fundamentally altered the relationship between register-transfer level (RTL) design and physical implementation in application-specific integrated circuits. The traditional sequential treatment of these two activities is no longer adequate for meeting the power, performance, and area targets of modern system-on-
This thesis investigates the possibility of dark matter arising from a confining dark SU(N) Yang-Mills sector with N=3,4,5. First, standard results from the established single-scalar-glueball framework are reviewed and numerically reproduced in order to follow the cosmological evolution through the confinement phase transition and extract the relic abundance. The results reproduce the expected qua
Grated cheese is a convenient and ready-to-use food product. However, due to its increased surface area, grated cheese is susceptible to spoilage. This master’s thesis aimed to improve the understanding of growth patterns of spoilage microorganisms in relation to intrinsic factors in both grated mozzarella and grated hard cheese. Cultivation of yeast and lactic acid bacteria, using pour plating- a
As population ageing deepens and rural-urban migration continues, the practice of ageing in place in rural China is facing new housing challenges. Many older people prefer to continue living in familiar villages, but the out-migration of adult children has made family care less stable. Institutional care can provide structured support, but it does not always fit their living habits or emotional ne
Artificial intelligence (AI) is playing an expanding role in infectious disease surveillance and intervention planning by enabling analysis of large-scale health data. One of the key challenges in this area is to characterize transmission within households and to identify factors that influence both infectivity and susceptibility. The present study focuses on the COVID-19 pandemic, which not only
The aim of this thesis is to examine how the public artworks Fossil Composition (1955), Stone Flower (1955) and Tousle (1952), through their bureaucratic municipal processes, reflect the broader ideological ideas of the welfare state, or Folkhemmet, between 1951 and 1956. It also aims to examine what notions of intended municipal identity can be identified through the discourses surrounding the ch
The Greenland Ice Sheet (GrIS) is seeing an accelerated rate of ice melt, which increasingly contributes to global sea-level rise. Studies have reported a growing mass imbalance coinciding with a widespread retreat of the island’s glacial termini. The associated discharge of ice is driven by submarine melting and ice breaking off glacial fronts, a process known as calving. The rate at which calvin
During the third long LHC shutdown (2026-2030), one of the four main experiments at CERN, ALICE, will undergo an extensive upgrade of the Inner Tracking System (ITS3). During this, the three innermost layers of the detector will be replaced by a novel technology, where wafer-scale stitched sensors will be bent into half-cylinder shape and placed one on top of the other, wrapping around the beam pi
Introduktion: Biokol från träpellets analyserades med BET-metoden för att undersöka hur pyrolystemperatur påverkar den specifika ytarean samt hur reproducerbar analysen är. Bakgrund: BET-analys används ofta för att bestämma specifik ytarea hos biokol, men resultaten påverkas starkt av faktorer såsom partikelstorlek, avgasning och materialets heterogenitet. För biokol saknas ofta standardiserade an
Surgical education is traditionally based on apprenticeship and supervised practice, but limited availability of experienced surgeons, restricted access to training cases, and subjective feedback create challenges for efficient surgical training. Solutions utilizing machine learning and computer vision for automating instrument tracking and automated phase recognition have been investigated in lap
