Drainage of peatlands causes changes in water table (WT), vegetation and decomposer community. As a consequence, decomposition patterns and carbon dynamics change, which is visible in altered Dissolved Organic Carbon (DOC) concentrations in ground and soil water. Additional changes in precipitation patterns towards more extreme drought and rain periods, as expected with climate change, cause furth

Det sker en ökning av dödliga polisskjutningar i USA och det är även ett problem i Sverige. Tidigare forskning finns kring polisskjutningar i jämförelser mellan länder, men det saknas något komparativt mellan USA och Sverige. Syftet med denna studie att få en bild av förekomsten av dödliga polisskjutningar i USA och Sverige samt se om det finns variabler som har något samband med dessa skjutningar

Forest ecosystems are important actors in climate change mitigation strategies through their abilities to act as both carbon sinks and sources. The commonly used forest management strategy of clearcutting has been suggested to be paired with large greenhouse gas emissions, increasing the need for research on the climate effect from alternative management strategies. Rumperöd forest is managed thro

This study looks at the change of the Urban Heat Island (UHI) intensity in Rio Park, Madrid, which during the course of the last 20 years has in essence been retransformed from an urban highway into a flourishing green park along the Manzanares river. The deconstruction of the M-30 highway started in 2005, was completely finished in 2015, and canopy growth in the area continued during the followin

Bacterial cellulose (BC) is a versatile and biocompatible polysaccharide produced by bacteria, with Komagataeibacter xylinus being the model species for its production. This polymer has unique properties that make it valuable in several applications, including as a rheology modifier in cosmetics. Cellugy, a Danish start-up, produces EcoFLEXY, a BC-based rheology modifier that enhances the viscosit

Denna studie undersöker orsakerna bakom könsgapet i tillgången till aktiebaserad finansiering för svenska start-ups inom IT och kommunikation. Studien bidrar till diskussioner om jämställdhet genom att presentera strategier för att skapa en mer inkluderande tillgång till riskkapital. Analysen utgår från följande tre forskningsfrågor: (F1) Påverkar kön svenska entreprenörers möjligheter att få aktiThis study examines the mechanisms behind the gender gap in equity-based start-up funding within the Information and Communication Technologies sector in Sweden and contributes to discussions on gender equality by presenting strategies for fostering inclusive access to equity-based capital. The analysis is guided by the following three research questions: (RQ 1) Does gender affect Swedish entrepre

The last mass-extinction event happened over 65 million years ago when an asteroid collided with earth, resulting in the loss of 76% of all species. Scientists now warn that we are on the precipice of a new mass-extinction, the responsibility of which can be placed entirely on one species, the homo sapiens. While some species of birds, bats, and arthropods are especially vulnerable, we are all int

Studiens syfte är att undersöka vad som motiverar unga vuxna att använda sig av sociala medier, hur deras användande ser ut, vilket typ av innehåll de får upp och deras upplevelser kring det innehåll som presenteras för dem. Studien utgår främst från den kvalitativa metoden fokusgruppsintervjuer, och det transkriberade innehållet analyserades sedan genom kodningsmetoden Summary-based reporting. Fo

Världen står inför en stor energifråga, nämligen hur man skall kunna fasa ut användning av sådana fossila bränslen som kol och olja. En lovande lösning är vätgas, eftersom den endast producerar vatten när den förbränns, vilket gör den mycket renare för miljön. Forskare utforskar sätt att producera vätgas med förnybar energi, vilket kan hjälpa till att minska vårt beroende av fossila bränslen och sBiomimetic models inspired by natural [FeFe] hydrogenases have good potential for clean hydrogen production. Improving these models to increase their efficiency is a challenge that requires further research and development. This study aims to explore the catalytic behavior of ruthenium-based clusters in proton reduction to create hydrogen production catalysts inspired by natural hydrogenases. Four

Through the tight link between plants and their pollinators, plant species often decline when their pollinators decline and vice versa. These nominal declines are well studied for many plant-pollinator networks. Less well known is the effect that the decline of a plant species has on the behaviour of its pollinators, and how potential changes in pollinator behaviour affect the reproductive success

This thesis explores the construction and negotiation of Tibetan identities through the lens of native Tibetan cinema, with a focus on Pema Tseden’s Balloon (2019). Drawing on theories of identity as construction, cultural hybridity, and minor cinema, the study examines how cinematic narratives and audience interpretations intersect to produce a nuanced understanding of Tibetan identities in conte

This thesis investigates how Chinese female stand-up comedians construct gendered narratives through humor and how female audiences interpret and respond to these performances. Focusing on two popular online shows—Stand-up Comedy and Its Friends and Comedy King (Stand-up Season)—the study examines how humor becomes a space for negotiating feminist expression under ideological, cultural, and commer

Examensarbetet utreder hur hanteringen av förorenade schaktmassor kan bli mer hållbar och cirkulär genom att tillämpa in-situ-tekniker. Syftet är att kartlägga befintliga och framväxande saneringsmetoder, identifiera tekniska, juridiska och ekonomiska hinder och kvantifiera möjliga klimat- och kostnadsvinster så att branschaktörer får ett beslutsunderlag för ökad lokal behandling och återanvändninThis thesis clarifies how the management of contaminated excavation soils can be made more sustainable and circular by applying in-situ techniques. Its aim is to map existing and emerging remediation methods, identify technical, legal and economic obstacles, and quantify potential climate and cost benefits, giving industry stakeholders a sound basis for increasing local treatment and reuse of soil

Growing research on ecosystem subsidies has emphasized the connection between aquatic and terrestrial ecosystems, with changes in one triggering responses in the other. In high mountain lakes, emerging aquatic insects are considered key aquatic subsidies and serve as an important nutrient resource for surrounding terrestrial ecosystem. The introduction of alien fish into these lakes, known to caus

Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus. In this work, we are investigating a XOS converting enzyme from the probiotic bacterium Levilactobacillus brevis (formerly Lactobac

Background: Opioid substitution treatment (OST) with methadone or buprenorphine is the most effective means of treating opioid dependence. If these substances are used by people who are not undergoing OST, they can however carry serious risks. This article examines the lifetime prevalence, motives, and drug sources for such use, as well as geographical differences in these variables. Methods: Stru

Aims Methadone and buprenorphine diversion by patients in opioid substitution treatment (OST) is a poorly understood phenomenon. We study the norms and attitudes on diversion among OST patients, including the role these norms and attitudes play as diversion risk factors. We also study whether perceived quality of care, social bonds to treatment staff, and deterrence can be associated with diversio

Att placeras på HVB är en av de mest ingripande insatserna inom socialt arbete. För ungdomar innebär den ofta att tillvaron blir präglad av förändring och en känsla av att framtiden är osäker. Licentiatuppsatsen fördjupar kunskapen kring existentiella utmaningar som kan uppstå i denna process. Studien har en teoretisk utgångspunkt i existentiell filosofi och fokuserar på hur grundläggande livsvillWhen young people are placed in residential care (HVB) it is one of the mostfar-reaching interventions in social work, often involving significantdisruptions to their everyday lives, future outlook, and sense of self. Whilesuch placements frequently raise questions about meaning and freedom thesechallenges remain largely unexplored from an existential perspective in bothresearch and practice. This
