Syftet med detta examensarbete har varit att utarbeta ett konkret förslag för logistisk implementering av industriella biometananläggningar i sydvästra Sverige. Genom att utnyttja restflöden från jord- och skogsbruk – såsom halm, GROT (grenar och toppar) samt såg- och kutterspån – undersöks möjligheten att ersätta fossil naturgas i det sydvästsvenska gasnätet med 100% förnybar biometan (uppgraderaThis thesis aims to develop a concrete proposal for the logistical implementation of industrial biomethane plants in southwestern Sweden. By utilizing residual biomass from agriculture and forestry, such as straw, forest residues (GROT), and sawdust, the study explores the feasibility of replacing fossil natural gas in the regional gas grid with 100% renewable biomethane (upgraded biogas). A comp

Utforskandet av nya roller av komplement proteinet C3 Komplementsystemet är en uråldrig evolutionär mekanism i det medfödda immunförsvaret och funkar som en av kroppens första försvarslinje. I detta gamla system finns det ett protein som sticker lite mer, ett protein som har en central roll i komplementsystemet, nämligen komplement protein C3. Inte nog med att den har en viktig roll i framkallninThe complement system is an ancient component of the immune system, comprising three pathways: classical, lectin and alternative pathways. Central to these pathways is complement component C3, which converges the three pathways. C3 can be enzymatically cleaved into C3a which functions as an anaphylatoxin, and C3b, which functions as an opsonin. Previously, C3 was understood as a serum protein, how

"om den här ifrågasatta lagen skulle blifva antagen, skulle följden blifva oupphörliga rättegångar eller, såsom ordspråket säger, >>hand i hår och knif på strupe>> emellan de bofaste och lapparne." This is how the member of parliament from Jämtland Olof Nikolaus Wagenius ends his speech in the second chamber on April 17, 1886. The tone is sharp, but far from an exception in the parliame

Seagrasses provide valuable ecosystem services, benefitting both marine species and humans by providing coastal protection and erosion control which is significant as 898 million people lived in low-elevation coastal zones in 2020. However, seagrasses worldwide have been declining and in Sweden, the eelgrass Zostera marina has decreased heavily since 1980. One cause for seagrass loss in temperate

Wood density is a crucial trait in trees influencing carbon storage in forests, yet dynamic global vegetation models (DGVMs) neglect its variability under different environmental conditions. For this thesis, I integrated environmentally-dependent wood density into the DGVM LPJ-GUESS by simulating mean annual tree ring density based on temperature variables. The model considers earlywood and latewo

En fungerande stadsbyggnad och översvämningriskhantering i Quezon City, Filippinerna, ett snabbt växande område med omfattande utbredning av informella bosättningar, är avgörande med tanke på den omfattande risken för översvämningar. Detta examensarbete syftar till att bidra till strategier för stadsplanering i översvämningsdrabbade områden genom att integrera en maskininlärningsmodell med stadsbyUrban development and flood risk management in Quezon City, Philippines, a rapidly urbanising area with extensive informal settlements, are critical given the city's vulnerability to flooding. This thesis aims to contribute to the theoretical framework for urban development in flood-prone areas by integrating a machine-learning model with contextual urban planning. The model uses a Random Fore

Critical scholarship has increasingly questioned the effectiveness of external menstrual health interventions in the Global South, often highlighting their lack of cultural sensitivity and potential to reinforce menstrual stigma. These critiques raise concerns not only about individual well-being, but also about broader questions of gendered inequality. Although such initiatives frequently center

State-controlled social media platforms can result in authoritarian soft power assets when the users' mediated communication extends across borders. Especially in times of hostile conflict and narrative divide, these transnational communication networks – without the coordination of the authoritarian state – can promote authoritarian narratives to non-domestic audiences when multilingual users

Dating the bottommost section of an ice core is often complicated by strong layer thinning and possible disturbances in the stratigraphy. The radioactive decay of atmospherically produced 36Cl and 10Be can provide age estimates, where traditional methods can no longer be used. In this study, we investigated ice from the bottom of the Skytrain ice core, which was drilled in West Antarctica next to

This study explores how everyday ferry travel in transit spaces create experiences through the interplay of mundane and extraordinary interactions, focusing on the Øresundslinjen ferry between Helsingborg, Sweden, and Helsingør, Denmark. Drawing on the concepts of mundane tourism, the new mobilities paradigm, tourist gaze, and service-scape theories were used to examine the social, spatial, and em

Sexual conflict over mating has been documented in many species, both in the field and in experimental studies. In pond damselflies (family Coenagrionidae), sexual conflict maintains female-limited color polymorphisms, with one female morph typically being a male mimic. However, it is not known whether sexual conflict can also explain the evolutionary origin of novel female morphs, and if so, what

Denna uppsats närmar sig svenskt plein-air måleri i Fontainebleau och inom konstnärskolonin Grèz-sur-Loing från slutet av 1800-talet genom längtans lins. Med utgångspunkt i temat nostalgi och apodemialgi – längtan hem och längtan att bort – undersöks landskapsmåleriet och hur det visualiserar teman om natur och modernitet. Denna tid av exil är en viktig punkt i svensk konsthistoria eftersom den haThis thesis examines late 19th-century Swedish plein-air painting in Fontainebleau and within the artists’ colony Grèz-sur-Loing through the lens of longing. Drawing on the theme of nostalgia and apodemialgia—longing for home and the longing to leave—it investigates how landscape painting visualizes themes of nature and modernity. This time of exile is an important point in Swedish art history as

Green ammonia synthesis from nitrogen via photocatalysis and electrocatalysis has emerged as a pivotal research focus in sustainable chemical processes. The efficient catalytic reduction of nitrogen necessitates concurrent nitrogen activation and hydrogen evolution suppression, representing a significant challenge. In this study, CuAu bimetallic-modified TiO2 catalysts were developed and engineere

The laminate flooring company Pergo (Europe) AB has during the last years identified an increasing market demand for customized flooring solutions. In the autumn of 2004 Pergo had no standardized product offer and the existing administrative process was not suited to produce and deliver customized products. Experiments concerning a new décor production technique with extensive potential based on d

Utgångspunkten är en fundering om vad det finns för alternativa sätt att utbilda i mångkulturell mångfald. Uppsatsen har fokuserat på Malmö Stads kontaktpersonsverksamhet, där man matchar ihop etablerade svenskar med nyanlända invandrare. Syftet är att beskriva vad några svenska personer upplever att de har lärt sig om sin nyanlände kontaktpersons kultur, hur de har förändrats, hur de kan använda

Vi lever i ett postmodernt samhälle där miljöproblem är ett stort fenomen som präglar vår kultur. I denna uppsats har vi studerat hur marknadsföring drar nytta av människors oro för miljön, genom grön marknadsföring. Vi har använt Ben & Jerry’s som fallstudie och gjort en semiotisk och retorisk analys av deras hemsida. En semiotisk analys synliggör tecken, symboler och associationer typiska fö
