Both the EU and Sweden aim to incorporate hydrogen to decarbonize industries and reduce fossil fuel dependence. Liquid Wind, a company focused on sustainable electro-fuel production, develops facilities to convert biogenic CO2 and renewable hydrogen into green electro-fuel eMethanol. Such facilities, handling flammable substances, require quantitative risk assessments (QRA). Currently, Hydrogen QR

This thesis explores patriarchal sexual scripts through network analysis of data collected in an anonymous survey with a final sample of N = 1.029 responses. The aim is both conceptual and methodological insofar as the project uses Gaussian Graphical Models to develop a radical feminist point about patriarchal sexuality. For this purpose, the concept patriarchal sexual scripts is developed from ra

Utsläpp från avloppsreningsverk påverkar våra sjöar och hav negativt och allt högre krav ställs på reningsprocesserna på avloppsreningsverken. Nya utsläppskrav kommer att presenteras i Avloppsdirektivet från EU under 2024 och kommer att vara vägledande för de utsläppskrav som finns på de svenska avloppsreningsverken. Strängare utsläppskrav för kväve och fosfor tvingar reningsverken att optimera siEmissions from wastewater treatment plants affect our lakes and seas negatively. Higher demands are therefore placed on the purification processes at the wastewater treatment plants. New emission requirements will be presented in the Wastewater Directive from the EU in 2024 and will be a guide for the emission requirements that exist for the Swedish wastewater treatment plants. Stricter emission r

Canada pledged to achieve net zero by 2050 and important efforts revolving around the energy transition of electricity generation systems toward renewables sources are being carried. Currently, most renewable systems developed are occurring on Indigenous communities’ lands for various reasons. Climatic conditions are suitable for solar and wind-based solutions, space is available, and this trend c

Rebound effects, though well-documented in consumption areas such as household energy consumption, have been far less explored in nutrition. This is despite the fact that the nutrition may be just as crucial of a consumption area when considering how to reduce carbon footprints in personal lifestyle choices. This thesis explores the existence of one of the possible mechanisms behind a rebound effe

This thesis is an investigation of sediment transport in the Piura River in Peru. Years of anthropogenic changes have redirected the river towards the south and have caused changes in the flow regimen (Alvarado Ancieta & Ettmer, 2007). It is suspected that the redirection towards the south has resulted in deposition of sediments which has reduced the capacity of the river in the lower reaches

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

The increasing urgency of climate change, coupled with the energy crisis and resource scarcity, demands radical and resilient building solutions. Buildings currently consume a significant portion of energy – in the Nordic context, primarily for indoor space conditioning – highlighting their vulnerability to future climate impacts. Free-running buildings, operating without any energy for heating,

Nitrification Inhibitors Have Minimal Impact on Microbial and Collembola Communities in Danish Arable Soil This study aimed to investigate the targeted and non-target impacts of nitrification inhibitors (NIs) on the soil microbial and collembola communities in arable soils under a spring barley cultivation system. By assessing soils where inhibitors were repeatedly applied alongside fertilizers,

This thesis explores the impact of NATO negotiations between Turkey and Sweden on the Kurdish diaspora in Sweden. To address this, this thesis has focused on the key concepts of identity, sense of belonging, integration and relationship with the state. To collect data, the method of semi-structured interviews has been used, which then was analysed using thematic analysis. This revealed that the ne

Technologies of green transitions, including electric vehicles and advanced battery systems, require vast amounts of lithium. Sites of lithium extraction are expanding rapidly to meet rising demand, with a wide assortment of actors seeking to capitalize on the opportunity. With lithium extraction known to pose various social and environmental threats to surrounding ecologies and communities, the a

”We will never become Russians”: the discourse concerning Russia as the Other in Swedish conservative daily press between 1890 and 1906. This study focuses on how three events unfolding in the Russian empire during the turn of the nineteenth century were portrayed in the Swedish conservative daily press. The depiction of the following events have been subject of examination: the russification of

This thesis is ultimately concerned with a natural and optimal generalization of the familiar Bell state measurement on four basis states. Measurements in quantum mechanics are interactive processes, meaning the observer actively changes the state they extract information from. Different measurements differ in the degree of the disturbance induced, and in the amount and type of information gained.

This thesis deals with language mixing in 20th century Japanese jazz, particularly the use of English. There have been multiple studies conducted on the language mixing phenomenon in Japanese pop-music (J-pop), a popular genre in Japan today. The results showcase that English is frequently used in J-pop, both inter-sentential and intra-sentential code-switching. The use of English has also been sh

Recently, the paper ”When Choices Are Mistakes” by Nielsen, Kirby, and John Rehbeck (2022) introduced a novel method to test axiomatic theories of choice under risk. This innovative approach opened new avenues for exploring decision- making processes. Ambiguity aversion, a distinct concept where probabilities of outcomes are unknown, is fundamental in understanding economic and financial decisions

Two-particle angular correlations were measured in proton-proton collisions for pions π, kaons K and protons p. The meson results show the expected peak predicted by theory. However the proton results (for baryon-baryon and antibaryon-antibaryon pairs) an anti-correlation is observed. This observation is rooted in the baryon formation after the collision.

Syfte: Studiens syfte är att öka kunskapen om det kollegiala stödet i äldreomsorgsverksamheter. Frågeställningar: ➢ Hur upplevs det kollegiala stödet i äldrevården? ➢ Hur upplevs det kollegiala stödet som ett sätt att hantera det fysiskt och psykiskt krävande arbetet? Metod: En kvalitativ studie där semistrukturerade intervjuer utgjorde det empiriska materialet, insamlat från nio intervjupersone

This project aims to use the Tröger’s base molecule to synthesize a linearly heptakis-Tröger’s base. The furthest this project reached was the synthesis of the linearly fused tris-Tröger’s base analogue. To reach this compound, nine synthesis steps were preformed starting with an aniline analogue. The aniline was first halogenated and then condensed into the first Tröger’s base analogue. This was

Citizen collaboration is essential to tackling global sustainability issues. People have different motivations for participating. However, there is a lack of studies on citizen motivations for participating in local sustainability initiatives. To address this gap, the present study looked into the motivations of the residents of the Sege Park neighbourhood in Malmö, Sweden. The study interviewed n

Järn är en metall som finns i överflöd på vår jord. Den är säker, är ett av de mest använda grundämnena genom den mänskliga historien och finns naturligt inom varje människa. När den kombineras med andra atomer kallade ligander för att bilda ett så kallat komplex, kan den ifall den får lov att absorbera ljus, uppvisa fotokatalytiska egenskaper. Detta innebär att den omvandlar det inkommande ljusetIron is one of the most versatile transition metals on the planet, and it is the fourth most plentiful element in the crust on earth. It is among numerous things, endogenously, vital to the human organism, and exogenously, safe to handle. When combined with ligands to form a complex, it exhibits qualities that of catalysing light into viable energy, which can be harnessed to sustain different elec
