Karakterisering av mikroplaster i biogödsel - insikter i partikelegenskaper och miljöpåverkan Mikroplaster i biogödsel kan bidra till att sprida giftiga föroreningar i miljön. När all vår plast bryts ner till mikro-plaster och hamnar i naturen kan den sprida toxiska ämnen och problem långt bortom den ursprungliga källan. Bio-gödsel från våra hushållssopor kan upplevas som en grön lösning – men deThe significant increase in global plastic production has led to its widespread environmental accu-mulation. Soil has become a major sink for microplastics, originating from sources like biofertilizers. This study aims to link the characteristics of microplastics in biofertilizer with their possible envi-ronmental effects, specifically focusing on the sorption of contaminants. Microscopy was emplo

The background for this thesis is that access to sustainable electricity is part of the United Nations’ Sustainable Development Goals for 2030. In Sub- Saharan Africa, approximately 570 million people lacked access to electricity in 2022. To expand access in rural areas, solar home systems and other off-grid solar products offer affordable and accessible solutions. However, as these systems reach

The legacy of colonialism still wields a powerful grip: „through the property it occupies, the capital it is financed by, the materials it is constructed from, the underpaid migrant labour that continues to construct it, and the expertise that benefits from it through accumulations of social and financial capital“ (Herscher, 2021). Sadly, nothing of this incomplete list is within the past; we are

På botten i en av Skånes största dricksvattensjöar gömmer sig gamla synder från förr. På sommaren kommer de till ytan och orsakar problem med vattnets kvalité och gör sjön ovälkomnande grön. I denna studie går vi till botten av problemet med förhöjda näringshalter i Vombsjön. Sedan en lång tid tillbaka har orenat avloppsvatten och vatten från jordbruksmark runnit in i Vombsjön. Vattnet har innIn this study, the internal load of phosphorus in Lake Vomb is explored. Years of external inputs from untreated sewage and agricultural runoff have built up tonnes of phosphorus in the lake sediment, periodically released causing HABs and impairing water quality. The aim of this study is to investigate how the internal load varies over a year and to explore correlations between internal loading,

This study aimed to explore how individuals with experience of homelessness perceived the available support services, as well as how they experienced their encounters with social workers, highlighting effective current practices and identifying areas needing improvement. Based on narrative interviews with six formerly homeless individuals in Stockholm, Sweden, their experiences were analysed using

Bygg- och fastighetssektorn står för en avsevärd del av Sveriges klimatpåverkan och resursanvändning, där stålproduktionen är en betydande faktor. Trots att stål är ett material med hög återvinningsgrad är direktåterbruket av bärande stålkomponenter i dagsläget begränsat. Detta utgör en outnyttjad potential för att minska koldioxidutsläpp och främja en cirkulär ekonomi, där Design för Demontering The construction and real estate sector accounts for a considerable share of Sweden's climate impact and resource use, with steel production being a significant factor. Although steel is a material with a high recycling rate, the direct reuse of load-bearing steel components is currently limited. This represents an untapped potential for reducing carbon dioxide emissions and promoting a circul

Julius Tröger first synthesised ‘C17H18N2’ as an unknown product from the condensation of anilines with formaldehyde. From that point on, the history of Tröger’s base (TB) has widely evolved as new applications for its characteristic rigid, chiral framework easy to functionalise. It is in the field of supramolecular chemistry that TB has gathered the most attention these last years. This work is f

This thesis investigates the relationship between Protestant and Catholic religious affiliation and union outcomes, as well as religiosity and union outcomes in Northern Ireland. I conduct a multinomial logistic regression analysis using pooled cross-sectional data from the Northern Ireland Life and Times survey from 1998–2023. I find that cohabitation has increased in the 21st century, and that r

History leaves its marks on the life of a city. As urban landscapes continue to expand and evolve, old industrial sites and urban functions are often left behind, fading into the margins of the contemporary city. This thesis seeks to explore how architecture and public space can breathe new life into these forgotten areas, reactivating them as meaningful parts of the city’s present and future.The

Inhalation of engineered nanoparticles that are handled as powders or sprays in consumer products poses a potential health risk. To investigate the effects of nanoparticles on human health, the Nano Aerosol Chamber for In-Vitro Toxicity (NACIVT) system has been designed for controlled deposition of aerosol particles onto cell cultures. The objective of this study was to estimate the deposited dose

The last century has been a turbulent period in Cambodia, yet in the recent decades it has emerged from conflicts and humanitarian crises and become one of the world’s fastest-growing economies. This transformation was enabled in large part by foreign aid (ODA) and foreign direct investment (FDI). This thesis analyses the mechanisms by which ODA and FDI influenced the economy individually and in c

As AI technologies are increasingly adopted to improve efficiency and support decision-making, it is important to understand how ethical principles are upheld in practice. The study aimed to identify these challenges and examine

Möjligheter och hinder med återanvändning av kanalsystem för ventilation Bygg- och fastighetssektorn behöver ställa om till en cirkulär ekonomi för att minska sin klimatpåverkan och uppkomst av avfall. Återanvändning av byggprodukter är en cirkulär metod som kan antas medföra en enkel och billig procedur jämfört med nyproduktion, inte minst för tillverkare som kan ta tillbaka använda produkter föThe construction sector accounts for 20 percent of Sweden's climate impact and 40 percent of all generated waste. Ventilation systems, together with other installations, represent about 10 percent of a building's climate impact during the construction phase. Reuse of building products is a circular method to prevent waste and reduce emissions, but reuse is not very common in the constructi

Cirkulärt byggande har blivit en allt viktigare del av klimatomställningen inom bygg- och fastighetssektorn. I takt med att klimatpåverkan från nyproduktion uppmärksammas, riktas fokus mot återbruk av byggmaterial som ett sätt att minska utsläpp och resursanvändning. Denna studie undersöker hur återbruk tillämpas i svenska kontorsombyggnationer, vilka material som återbrukas, vilka ekonomiska och Circular construction is becoming an increasingly vital part of the climate transition within the building and real estate sector. As the environmental impact of new construction gains more attention, focus shifts toward the reuse of building materials as a means to reduce emissions and resource consumption. This study investigates how reuse is applied in office renovations in Sweden, what types o
