X-ray absorption spectroscopy (XAS) measurements were performed at the oxygen K-edge using aqueous solutions of succinic and maleic acids. Molecular dynamics simulations were employed to perform structural sampling and calculate the theoretical spectra using the framework of the density functional theory. When the pH was varied, the first peak in the XAS profiles exhibited different behaviors for
3I/ATLAS is the third interstellar object discovered to date, following 1I/‘Oumuamua and 2I/Borisov. Its unusually high excess velocity and active cometary nature make it a key probe of the Galactic population of icy planetesimals. Understanding its origin requires its past trajectory through the Galaxy to be traced and the possible role of stellar encounters to be assessed, both as a potential or
Context. A growing number of white dwarfs (WDs) exhibit one or more signs of remnant planetary systems, including transits, infrared excesses, and atmospheric metal pollution. WD 1054-226 stands out for its unique, highly structured, and persistent photometric variability.Aims. We investigate the long-term stability and nature of the periodic signals observed in WD 1054-226 to better understand th
Craft is re-emerging in debates on improving contemporary work. A recurring theme in research on craft is its potential to thwart alienation, which is considered one of the central pathologies of modern work. Through a case study of the Swedish craft beer community, we examine craft’s potential for de-alienating work. Drawing on Jaeggi’s conception of alienation as a relation of relationlessness,
Lignins are aromatic polymers found in fibrous plants, and a major side-product of paper pulping. They are under exploited due to a combination of economic and technical challenges. Valorisation efforts aim to resolve this, but these rely on informative and reliable analytical feedback. The diverse and complex structures of compounds found in lignins makes analysis difficult. This thesis outlines
Rotating Detonation Combustors (RDCs) offer a promising alternative to conventional gas turbines by utilising continuous supersonic detonation waves for theoretical pressure-gain combustion, boosting thermal efficiencies significantly. However, developing reliable designs is exceptionally challenging because the extreme combustor environments restrict experimental sensors from capturing sub-micros

Drawing on fine-grained ethnographies from Bissau, Chile, China, Egypt, Ecuador and Nepal, this volume explores how politically, religiously and (sub-)culturally inspired Utopias motivate youth in the Global South to imagine, enact and embody what was missing in the past and present. As a fluid age cohort and a social category between childhood and adulthood – and hence with tenuous links to the s
Climate warming profoundly alters cryospheric hydrological cycles, exacerbating the challenge of simulating the poorly understood processes, particularly in complex, glacier- and permafrost-dominated headwater basins. This difficulty centers on accurately representing the compound runoff regimes generated by the complex, overlapping interactions between rainfall and multiple cryospheric melt proce
Nära relationer är avgörande för människors välbefinnande. Anknytningsteori utgår från att tidiga erfarenheter med omsorgsfigurer (oftast föräldrar) under uppväxten formar hur individer lär sig förstå sig själva, andra och omvärlden. Genom upprepade interaktioner med omsorgsfigurer i situationer präglade av distress utvecklar barn mentala bilder som liknar ett manuskript, som innehåller implicit kClose relationships are fundamental to human wellbeing. Attachment theory posits that early caregiving experiences shape how individuals come to understand themselves, others, and the world. Through repeated caregiving interactions in situations of distress, children develop script-like mental structures (i.e., attachment schemas). Attachment schemas, thus, hold implicit knowledge about availabili
Water-related damage represents a major challenge in the built environment, with consequences for building performance and occupant health. While external factors can contribute, this study focuses on damage originating from internal sources. Deficiencies and failures in building service systems, water supply, sewage, and technical installations, constitute a substantial problem, leading to repair
The genus Mentha is highly valued in pharmaceutical, culinary, and personal care industries due to its rich aromatic and pharmacological traits. However, its complex taxonomy and genetic diversity create challenges for breeding programs focused on aroma and therapeutic qualities. To address these challenges, this study developedand validated a rapid, semi-quantitative metabotyping method to efficiThe genus Mentha is highly valued in pharmaceutical, culinary, and personal care industries due to its rich aromatic and pharmacological traits.

Stadsmiljöavtal är ett sätt för staten att påverka kommuner och regioner att göra mer för att öka andelen hållbara transporter. Stadsmiljöavtalet introducerades 2015 som ett styrmedel för det ändamålet och Trafikverket fick i början av 2015 ett regeringsuppdrag att ta fram ett förslag på ett ramverk för stadsmiljöavtal. Syftet med denna rapport är att beskriva de faktiska effekterna av åtgärder oc
