Naturliga metanutsläpp sker från våra våtmarker världen över. Metan produceras naturligt genom nedbrytning i de syrefria förhållanden som en våtmark erbjuder. För att bättre kunna modellera och skala upp hur mycker metan som faktiskt släpps ut från dessa våtmarker måste ytterligare förståelse skapas över varför metanutsläppen varierar så kraftigt både i tid och rum. Denna studie försöker öka först

Populärvetenskaplig sammanfattning: Mer än två miljarder människor, mestadels i utvecklingsländer, saknar tillgång till moderna energikällor eller elektricitet. Behovet av rena, effektiva, pålitliga och ekonomiskt överkomliga energitjänster är en viktig fråga i utvecklingsländer, särskilt för landsbygden, där merparten av befolkningen bor. Förnyelsebara energikällor i form av småskaliga vattenkrafOver 2 billion people, mostly in developing countries, have no access to modern fuels or electricity. The necessity of clean, efficient, reliable and affordable energy services is a crucial issue in developing countries, especially in the context of rural areas where the majority of the people lives. Renewable energy sources in shape of small-scale hydropower systems are a complement or alternativ

Today wind power developers are exploring the possibilities of establishing wind turbines in forest areas, therefore improved sound prediction models for complex terrains are valuable. The Swedish model used today is only applicable for hard flat ground without any vegetation, and is not adjustable to any meteorological parameters except the wind speed. The companies DELTA, DONG Energy and EMD Int

När passagerarfartyget Marco Polo gick på grund utanför Skånes kust hösten 2023 läckte olja ut i havet. Men vad händer med livet under ytan efter ett sådant oljeutsläpp? I denna studie har blåmusslor använts som naturens egna vittnen och deras skal bär på spår av hur djur anpassar sig till en förorenad värld. När ett fartyg går på grund och släpper ut olja i havet är det inte bara stränderna som

Cultural tourism and cultural heritage management, while distinct disciplines with differing foci, are also inherently intertwined. However, conflicts between the two often arise due to the diverse number of stakeholders and interests involved in either the travel industry or the conservation and protection of cultural heritage. Despite this, cultural tourism can greatly benefit the conservation o

Luminiscensdatering är en väletablerad dateringsmetod inom geologisk och arkeologisk forskning. Dock är användandet av luminiscensdatering, mer specifikt optiskt stimulerad luminiscens (OSL), fortfarande underrepresenterat inom norsk arkeologi. Denna studie ämnar utreda lämpligheten av denna dateringsmetod som ett användbart alternativ för utgrävningar av Stenålderslokaler på den norska kusten. De

Four directional and positional variants of sulfonamide-derivatized galactopyranosides were synthesized and evaluated against human galectin-1, -3, -4C (C-terminal), -7, -8N (N-terminal), -8C (C-terminal), -9N (N-terminal), and -9C (C-terminal), which revealed that one of the sulfonamide positions and directionalities (methyl 3-{4-[2-(phenylsulfonylamino)-phenyl]-triazolyl}-3-deoxy-α-D-galactopyra

The ubiquity of phospho-ligands suggests that phosphate binding emerged at the earliest stage of protein evolution. To evaluate this hypothesis and unravel its details, we identified all phosphate-binding protein lineages in the Evolutionary Classification of Protein Domains database. We found at least 250 independent evolutionary lineages that bind small molecule cofactors and metabolites with ph

GTP hydrolysis is a biologically crucial reaction, being involved in regulating almost all cellular processes. As a result, the enzymes that catalyze this reaction are among the most important drug targets. Despite their vital importance and decades of substantial research effort, the fundamental mechanism of enzyme-catalyzed GTP hydrolysis by GTPases remains highly controversial. Specifically, ho

Despite the abundance of membrane-associated enzymes, the mechanism by which membrane binding stabilizes these enzymes and stimulates their catalysis remains largely unknown. Serum paraoxonase-1 (PON1) is a lipophilic lactonase whose stability and enzymatic activity are dramatically stimulated when associated with high-density lipoprotein (HDL) particles. Our mutational and structural analyses, co

Accurate detection of cancer-associated molecular abnormalities in tumors could make cancer treatment more personalized. Affibody molecules enable high contrast imaging of tumor-associated protein expression shortly after injection. The use of the generator-produced positron-emitting radionuclide (68)Ga should increase sensitivity of HER2 imaging. The chemical nature of radionuclides and chelators

Pharmaceutical residues discharged through insufficiently treated or untreated wastewater enter aquatic environments, where they may adversely impact organisms such as aquatic invertebrates. Ozonation, an advanced wastewater treatment technique, has been successfully implemented to enhance the removal of a broad range of pharmaceuticals, however diverse byproducts and transformation products that
