Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. Studien undersöker hur betongens egenskaper påverkas av olika halter absorptionshämmare. Dels studerades glimmerrikt bergkrossmaterial, soThis master thesis evaluates an absorption-inhibiting admixture to enable the use of demanding aggregate materials in concrete production. This was achieved by investigating how the properties of concrete were affected by different levels of absorption inhibitor. Firstly, mica-rich aggre-gate material was studied, which, due to its high mica mineral content, has a high water absorption rate that i

Syftet med denna studie var att undersöka psykometriska egenskaper för Compassion fatigue inventory (CFI), som ett instrument för att mäta compassion fatigue hos lärare. Vi undersökte även om nivån av compassion fatigue kunde predicera lärares benägenhet att agera i en mobbningssituation. En konfirmatorisk faktoranalys utfördes och vi fann att den gav otillräckligt stöd för den tre-faktorstruktur The purpose of this study was to investigate the psychometric properties of the Compassion Fatigue Inventory (CFI) as a tool for measuring compassion fatigue among teachers. We also examined whether the level of compassion fatigue could predict teachers' propensity to act in a bullying situation. A confirmatory factor analysis was performed, and we found that it provided insufficient support f

This is a qualitative study implemented through semi structured interviews involving seven young adults born in Sweden with parents born in other countries. The aim of this study is to examine how people born in Sweden with parents born in non-Nordic countries experienced their elementary school and if their foreign background affected their schooling and their current lives in some way. The concl

Denna studie undersökte ungdomars erfarenheter av viktmobbning i en svensk skolkontext, samt hur ungdomar upplever skolans strategier för att hantera viktmobbning och vilka insatser de önskar att skolan hade vidtagit. Eftersom tidigare forskning som fokuserar på själva upplevelsen av viktmobbning är begränsad, gjordes en explorativ kvalitativ studie där en kritisk realistisk position intogs för atThe aim of this study was to investigate adolescents’ experiences of weight- related bullying in a Swedish school context, how they experience the schools’ strategies for weight-related bullying and which actions they wished the schools had taken. Since previous research on the subject is limited, an explorative qualitative study was conducted in which a critical realist position was adopted. The

I Sverige har alla rätt till skydd av personuppgifter, rätt att ta del av allmänna handlingar och yttrandefrihet. Rättigheterna skyddas av såväl våra nationella grundlagar som av EU:s primärrätt och EKMR. Det är dock inte ovanligt att det uppstår situationer där dessa rättigheter ställs emot varandra. Exempel på sådana situationer är när en enskild begär att dennes personuppgifter tas bort från enEveryone in Sweden has the right to protection of personal data, the right to access public documents, and freedom of expression. These rights are protected by our national constitution, EU primary law, and the European Convention on Human Rights. However, it is not uncommon for situations to arise where these rights conflict each other. Such an example is when an individual requests that their pe

Adults with a history of substance abuse constitute a marginalized group whose experiences of contact with social services are rarely highlighted in research. This study aimed to explore how clients with prior substance abuse problems experience the treatment they received within the social services’ unit for financial assistance and housing, and how such treatment influences their openness to rec

Mat är väsentligt för människan och är även en stor del av hennes kultur. Då mat är en så stor del av människans vardag så är det inte konstigt att det även förekommer i det innehåll hon publicerar på sociala medier som Instagram. Vi har myntat begreppet slampig matlagning som innefattar det matinnehåll på internet som likt food porn enbart ska konsumeras med ögonen. Till skillnad från food porn,

Studying the composition of exoplanets is one of the most promising approaches to observationally constrain planet formation and evolution processes. However, this endeavour is complicated for small exoplanets by the fact that a wide range of compositions are compatible with their observed bulk properties. To overcome this issue, we identify triangular regions in the mass-radius space where part o

A search for pair-production of vector-like leptons is presented, considering their decays into a third-generation Standard Model (SM) quark and a vector leptoquark (U1) as predicted by an ultraviolet-complete extension of the SM, referred to as the ‘4321’ model. Given the assumed decay of U1 into third-generation SM fermions, the final state can contain multiple τ-leptons and b-quarks. This searc

Extractivism is a global phenomenon driven by the logic of capitalism that is manifested chiefly in mining, but also in agribusiness. Women around the world have emerged as leaders of resistance movements against extractivism. In this article, we question this recurrent theme in political ecology literature based on ethnographic fieldwork in southern Ecuador, where resistance has been less success

Extractivist projects are causing widespread socio-ecological destruction across Indonesia, impacting ecosystems, rural communities, and Indigenous ways of life. At the forefronts of socio-ecological collapse, women are increasingly taking up leadership roles in environmental activism. Simultaneously, women environmental defenders (WEDs) are experiencing a growing crisis of violent repression. Thi

The extensive use of neonicotinoids has raised concerns about their impact on pollinators like hoverflies, which are vital for pollination and ecosystem health. This study develops and validates a green extraction method using Supercritical Fluid Extraction (SFE), coupled with HPLC (High Performance Liquid Chromatography) - MS/MS (Mass Spectrometry) for selective analysis. SFE was employed as a m

Denna studie analyserar det uppmärksammade toppmötet mellan Ukrainas president Volodymyr Zelensky och USA:s president Donald Trump den 28 februari 2025, som avvek från traditionella diplomatiska normer. Syftet är att förstå vilka roller USA och Ukraina intog under samtalet genom att tillämpa ett rollteoretiskt ramverk hämtat från K.J Holsti och Lisbeth Aggestam. Som material för studien användes e

With Artificial Intelligence (AI) relying heavily on vast datasets, including publicly available personal online data and increasing amounts of fines for data breaches the individuals demand for control over personal data increases. The purpose of this thesis is to analyze the efficacy of the GDPR in granting data subjects control over their personal data when they are used to train AI. Therefore,

Background: The Construction sector is globally one of the most resource-intensive sectors that accounts for significant material consumption and waste generation. Approximately 10% of Sweden’s construction and demolition waste consists of material waste. Alongside this 30 -35% of the total production costs are linked to waste and spillage. Purpose and research questions: The study aims to analy

Early diagnosis of colorectal cancer (CRC) is crucial for successful treatment and mortality reduction. In this regard, blood-based tests play an indispensable role. Current research is focused on molecules actively secreted by tumor cells into small extracellular vesicles (EVs). This four-phase study included 613 CRC patients, 446 controls, and 120 precancerous lesions. High-throughput transcript
