Introduction: Intumescent fire-retardant (IFR) coatings are widely used to improve fire resistance of wood-based materials by forming an insulating char layer upon heating. Background: The performance of IFR coatings depend on both formulation variables, such as binder, charring agent (CA), blowing agent (BA), acid source as well as environmental exposure which may influence the durability (long
In the 1980's the process of high-order harmonic generation (HHG) was discovered. It was later shown that HHG produces attosecond pulse trains (APTs), with 1 as = 10^(-18) s, using a photoelectron interferometric technique called reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). RABBIT uses a combination of an APT, which ionizes a gas, and an infrared (IR
A multicoincidence set-up for environmental monitoring first presented by Hrabar et al., 2025 was further characterized and developed using additional samples and improved detector components. The set-up consists of a single-sided silicon strip detector (SSSD) and a system of high-purity germanium (HPGe) crystals called COMPEX, surrounded by an anti-Compton shield (ACS) consisting of bismuth-germa
Syfte & mål: Syftet med studien är att undersöka vilka urbana grönstrategier som används i kompakta stadsmiljöer, samt vilka utmaningar, miljömässiga och sociala effekter som finns kopplade till lösningarna. Målet är att skapa en ökad förståelse för hur vegetation kan integreras och bidra till en mer hållbar stadsutveckling. Problemställning: Ökad urbanisering och klimatförändringar har bidAim & goal: The purpose of this study is to investigate which green strategies are used in compact urban environments, as well as what challenges, environmental and social impact are linked to the solutions. The goal is to create an increased understanding of how vegetation can be integrated and contribute to more sustainable urban development. Research questions: Increased urbanization and
I denna registerbaserade studie undersöktes matematik- och bildbetyg hos 14 322 svenska individer med språkstörning. Eftersom språkförmåga påverkar lärande och olika skolämnen ställer skilda språkliga krav, bör elever med olika typer av språkstörning uppvisa olika prestationsmönster i matematik och bild. Genom registerdata undersöktes dessa mönster på gruppnivå för att bidra till ökad kunskap och
This thesis explores the tensions between second-hand clothing consumption enabled by digital platforms such as Vinted and Sellpy as sustainable alternatives to fast fashion. Rather than treating the narratives at face value, we critically examine how service design elements on second-hand digital platforms mirror those of fast fashion. By keeping our focus on Generation Z consumers, we draw on So
This study assesses the suitability of large-scale greening projects in urban areas based on the Berlin Climate Adaptation Act in three study areas in Berlin, namely Mehringplatz, Treptower Straße Nord, and Drontheimer Straße, which were chosen through a selection process using multiple indicators. The reason for this study is to analyse the newly passed Berlin Climate Adaptation Act (KAnGBln), wh
This thesis investigates the quantum Mpemba effect, where an initially hotter system cools down faster than an initially colder one. This was demonstrated in a qubit system coupled to two environments. A thermal state is chosen as the initial state and then left to freely equilibrate. It was shown that the initial thermal state can be chosen in a way to accelerate the resulting relaxation process.
This study examines how the institutional and governance arrangements established under Namibia's Communal Land Reform Act (CLRA) of 2002 shape the equitable administration of indigenous communal land rights, with particular focus on the San community. Drawing on institutional theory and property rights theory as complementary analytical frameworks, and employing qualitative document analy
HTTP-klienter används för att hämta data från servrar över ett nätverk. Det existerar flera olika användningsscenarier för dessa klienter. Detta examensarbete fokuserar på och undersöker användningen av tre olika HTTP-klienter i ett Spring Boot-system ur ett implementerings- och prestandaperspektiv. Systemet som användes var en mock-up skapad av IKEA för att efterlikna deras faktiska produktionssyHTTP clients are used to gather data from servers over a network. Several different usage scenarios for HTTP clients exist. This thesis focused on and investigated the usage of three different HTTP clients in a Spring Boot system from the perspective of implementation and performance. This system was a mock-up made by IKEA to mimic their real live Spring Boot system. The research focused on compar
Immaterialrätten använder sig av fiktiva figurer antingen uttryckligen eller indirekt för att skapa objektiva bedömningar på respektive immaterialrättsliga område. Uppsatsen riktar in sig på vilken funktion de fiktiva figurerna genomsnittskonsumenten inom varumärkesrätten och den kunnige användaren inom mönsterrätten har vid bedömning av skyddsförutsättningarna och intrång. Med betoning på rättsprIntellectual property use the fictional persons either direct or indirect to create objetive judgments in legal protection requirements and infringement in all areas of intellectual property law. This thesis examines on the function of the fictional persons, the average consumer in trademark law and the informed user in design protection law, to assessing the conditions for protection and in the e
This thesis examines how Swedish legal and administrative frameworks governing LKAB’s mining operations have historically produced and reproduced the invisibility of Sámi land use, and how these patterns of exclusion continue to be mobilized within contemporary green transition justifications. Drawing on settler colonial theory and anopticism, the study argues that Sámi exclusion within Swedish re
The Stochastic Alpha Beta Rho (SABR) stochastic volatility model is widely used to price European options, but the lack of an exact closed-form solution leaves practitioners choosing between an analytical asymptotic approximation that loses accuracy in certain cases, and grid-based numerical solvers that must be rerun for every parameter set. This thesis investigates the application of a parametri
The thesis explores historical document dating based solely on vocabulary. That is, we do not consider contextual clues such as years or mentions of historical events in the classification. Both a probability model based on previous research as well as a modern deep learning model using RoBERTa are considered. The thesis demonstrates the difficulty of striking an equilibrium between complexity and
Threats and violence directed towards social workers have been recognised as a growing occupational issue within social work, both nationally and internationally. Previous research shows that social workers frequently encounter threatening situations in connection with the exercise of public authority and client interactions, which may affect both their work environment and professional practice.
The penal-welfare nexus examines new developments in the relationship between the welfare and penal systems. In this regard, in recent years it has been described a process of penalisation of the welfare system has been described, associated with the adoption of punitive conditionality, a specific type of conditionality system, based on principles of discipline and behavioural control, where the s
K-pop has become one of the most influential forces in the music industry that create commercially significant human brands with a significant amount of fan base. Traditionally, consumer-brand relationship (CBR) literature has focused on how consumers interact with product brands grounded on a Western individualistic and dyadic perspective. However, this framework does not adequately explain how c
I och med elektrifieringen av energisektorn ställs höga krav på ökad inhemsk produktion av elektricitet i Sverige. På grund av den nuvarande fördelningen, där en stor del av produktionen sker i norra Sverige medan konsumtionen är koncentrerad till södra delarna av landet, är behovet extra stort i elområde 4 (SE4). Ett län som möter extra stora utmaningar är Skåne där självförsörjningsgraden för elThe current electrification of the energy sector puts high demands on increasing domestic electricity production in Sweden. This issue is enhanced by the current regional imbalance between supply and demand, while a major share of electricity generation is located in northern Sweden, consumption is concentrated in the south. Consequently, the need for new production is particularly great in electr
