Lignin is a by-product from the paper industry and has shown good liquid barrier properties according to previous studies. The objective of this work was therefore to study the liquid barrier properties of hydrotropic extracted lignin through steam explosion (STEX), obtained from spruce. The lignin was dissolved in three different solvents (concentrations: acetone 65 %v/v, ethanol (EtOH) 80%v/v an
This thesis explores how climate change concern is polarised in Sweden, with the aim to increase the understanding to detect social impediments to successful progress on the issue, as well as to prevent conflictual divides. The thesis examines the distribution of climate attitudes through three different forms of polarisation: distributive opinion polarisation, group-based (opinion) polarisation,
Efficient inventory management is crucial for successful supply chain management with it attributing up to 30% of an organization’s supply chain costs. A key strategic decision in inventory management remains whether to centralize or decentralize inventory with both decisions having their advantages and disadvantages. Most studies highlight the importance of an organizations supply chain network i
While vital to Indonesia’s economic growth, the textile industry has exacerbated textile waste generation and environmental degradation, posing urgent sustainability challenges. Rising unemployment further compounds these issues, prompting policy responses such as the Bappenas’ Circular Economy Roadmap and National Action Plan 2025–2045, which aim to drive circularity and generate employment oppor
Denna studie undersöker hur villkoren för offentliga upphandlingar, styrda av Lagen om offentlig upphandling (LOU), påverkar användarvänligheten av elektroniska journalsystem inom svensk sjukvård, med fokus på systemen Cosmic och Millennium/SDV. Genom en kvalitativ metod med intervjuer med vårdpersonal och experter, samt analys utifrån teorier som Technology Acceptance Model (TAM) och IS Success M
This study aims to analyze how social welfare recipients are constructed in the political debate in Sweden. This has been done with a textual analysis of the protocol of the Swedish Parliament’s debates from January to March 2019. The method that’s been used is a textual analysis, and at the center of the analysis are theoretical concepts as norms and Jönson’s analysis of perspectives. The results
Achieving the Agenda 2030 requires the adoption and implementation of the goals at all levels of the government from the national to subnational level. Cambodia, as a member state of the UN, under the Cambodia Sustainable Development Goals (CSDG) Framework has also made a commitment to localise the SDGs to the subnational level. However, after the adoption of the CSDG framework in 2018, the progre
Parallel to the intensified digitization of financial transactions, an ancient informal system continues to operate in the shadows, exerting a significant influence on global financial structures. Hawala, as this system is known, is recognized for its dual nature, allowing it to function as a legitimate financial system, while its informal structure, particularly its lack of governmental oversight
In recent decades, digital markets have become one of the most significant and debated areas not only in the world of politics and economics, but also in legal doctrine and practice. The rapid evolution of dynamic digital markets, coupled with the outline of the Digital Markets Act (DMA), has led to significant debate within EU competition law on the appropriate balance between ex-ante and ex-post
The transport sector contributes significantly to air pollution and requires suitable alternatives to help mitigate climate change. In the municipalities of Sjöbo, Svalöv and Tomelilla in Skåne, Sweden, Skånetrafiken is currently running a pilot project for on-demand public transport, called SkåneFlex. This study aims to examine the reasoning behind the design of SkåneFlex and to explore whether i
This thesis evaluates an ensemble-based framework for predicting stock prices using pretrained transformer models for sentiment analysis and locally trained transformers for time series forecasting. Sentiment signals were generated from financial news using FinBERT, RoBERTa, and VADER, then combined with historical stock price data from Refinitiv Eikon. To enhance label quality, a custom ensemble
This master’s thesis explores the design of monopile foundations for a conceptual offshore wind farm in the Golfo de Cádiz, Spain. It uses a one-dimensional (1D) finite element (FE) modeling approach, based on the PISA-study. With the PISAstudy, new design models are available, which replace the traditionally used p-y method. A central part of this thesis is the Abaqus software, which is used to m
Per- and polyfluoroalkyl substances (PFAS) include a large group of chemicals that has been used for many decades because of their mechanical and chemical stability. They owe these unique features due to the strong C-F bonds in their molecules. PFAS can be fully or partly fluorinated and the more fluorinated they get, the more persistent they become. They have been used in several industries such
This qualitative study aimed to explore the perceptions of social workers in various professional roles—social secretaries, counselors, and family therapists, regarding sibling abuse, and to examine whether their perspectives differ. The study also sought to investigate the potential consequences associated with a normalized view of sibling abuse for the children involved. Semi-structured intervie
Sjön Hummeln (57°22´N, 16°15´Ö) i sydöstra Sverige har bildats av ett nedslag, som bekräftats nyligen. I ett tidigare arbete togs en borrkärna, till 160 meters djup, upp från strukturen. Lagerföljden dokumenterades och daterades utifrån hittade mikrofossil. Dateringen blev då: kambrium – ordovicium – kambrium. De har daterat nedslaget som bildade Hummeln till ordovicium (488 – 444 Ma). Man har sen
This thesis explores how creative professionals in a global automotive company's advanced design department navigate the creative process when designing for uncertain long-term futures. Through ten semi-structured interviews and an interpretive, qualitative approach, the study investigates how meaning is constructed and ideas are developed in contexts lacking clear problems, timelines, or eval
This paper examines the connection between inflation and long-term economic growth in the European Union by using a panel data analysis over the period 1983-2023. The study is built on earlier research which indicates that inflation may have a negative impact on economic growth but especially at higher levels. Relying on both exogenous and endogenous growth theories, this study also highlights the
I detta examensarbete studerades modellering och simulering av SSAB:s hetvattensystem i Borlänge baserat på systembeskrivningar och befintliga data. Enkelt uttryckt representerar detta system SSAB:s interna fjärrvärmenät, vilket försörjer anläggningens byggnader med hetvatten för både uppvärmning och tappvarmvatten. Även om en del av den producerade värmen förbrukas av processer och av kommunens fIn this thesis, the modeling and simulation of SSAB’s hot water system in Borlänge was studied based on system descriptions and existing data. In simple terms, this system represents the internal district heating network of SSAB, which supplies hot water to the buildings of the facilities, both for heating and warm water consumption. While some amount of the produced heat is consumed by processes
Wetlands are one of the most precious ecosystems in the world. They are important be-cause of their high biological diversity and unique properties, such as water purification and carbon sequestration. Yet, wetlands are also one of the most endangered ecosystems due to land draining. In Sweden, wetlands have been drained för centuries due to the lack of arable land. The draining can have been acco
This thesis examines the economic impact of US governors. It focuses specifically on crossover governors – who serve in a state politically dominated by the other major party – to analyse the impact of governors operating in politically adverse environments. Employing the synthetic-control method, it conducts counterfactual analyses of eight such governors from the 2000s and 2010s across six macro
