This thesis explores and evaluates the potential of using mathematical models to support production planning in sawmills. The study was conducted in collaboration with Södra Skogsägarna ekonomisk förening, using one of their sawmills as a case for model development and evaluation. The goal of the thesis is to apply existing quantitative tools and theory from academic literature to develop a p

This thesis examines the contemporaneous effect of a fuel price increase on the fishing effort in the EU’s fleet, comparing the small-scale fleet segment and the large-scale fleet segment. Using quarterly country-level panel data on fishing effort and fuel prices from 2021 to 2023, coefficients for the fuel price elasticity of effort are estimated through two fixed effects regressions using OLS. T

This paper examines the impact of the 2022 Russian airspace closure on bilateral trade flows between four Nordic countries (Sweden, Norway, Finland, and Denmark) and two East Asian economies (Japan and South Korea). By employing a novel approach combining Coarsened Exact Matching with the Synthetic Control Method, a synthetic control unit is constructed for each of the sixteen country-pairs, allow

PFAS are a group of persistent and harmful chemicals that are widely used in both industrial applications and consumer products. PFAS are commonly detected in the environment and pose health concerns. Adsorption by GAC is considered an effective treatment method for removing PFAS from water. After a certain period of operation, GAC requires high-temperature incineration as disposal method. Another

Agility has emerged as a strategic ideal across many sectors, especially within financial institutions facing heightened pressure to respond swiftly to technological disruption, regulatory shifts, and market volatility. While commonly positioned as a solution to organizational inertia, agility is often promoted through leadership programs and strategic narratives that assume a shared understanding

The importance of a company’s go-to-market strategy when launching a new product cannot be stressed enough, a field that is highly researched. But what happens when a product enters a market, fails and an attempt to re-launch it is being made? Re-entry theory is a subdivision of go-to-market theory that although highly important, little research and few theories can be found, creating a gap and a

This thesis examines whether corporate green bond issuance leads to measurable improvements in environmental performance among European firms in high-emitting sectors. Using firm-level panel data from 2015–2022, we match green bond issuers with conventional bond issuers using nearest-neighbour matching with Mahalanobis distance. Employing a difference-in-differences approach, we analyse changes in

In response to the emergency of climate change, green growth has emerged as an attractive pathway towards sustainable development. The environmental feasibility and economic consequences of green growth is a much debated topic among scholars. This thesis provides a panel data analysis of the relationship between green growth and economic performance in the industrial economies of Germany and Czech

This is a quantitative study that aims to investigate the labor market integration of foreign-born people. The purpose of the study is to analyze whether gender and class - based on the concepts of habitus, cultural and symbolic capital, and symbolic violence - are variables that affect how foreign-born people's qualifications and skills are utilized in the Swedish labor market, as well as the

This thesis investigates the open stormwater system in Augustenborg, Malmö, and aims to understand the past political goals and compare them with the present day structures, their current condition and how people interact with them. Drawing on planning documents and related sources from the time of the system’s development, the study explores the political and ecological goals that underpinned its

I omställningen till fossilfria lösningar har grön vätgas och ammoniak visat på att vara lovande energibärande bränsle. Att tillverka ammoniak med vätgas från förnybara energikällor kräver däremot stora mängder energi, och det är just därför denna studie är relevant. Genom att designa och simulera en ammoniakproduktion baserat på en 200MW elektrolysör med fokus på värmeintegration, har stora vinstGreen ammonia, produced from renewable hydrogen, is emerging as an important energy carrier and decarbonized fertilizer alternative. However, its production is highly energy-intensive, making process efficiency critical to its commercial viability. This study investigates how targeted heat integration can enhance the energy and cost efficiency of green ammonia production based on a 200 MW PEM elec

Consumer choices around plant-based diets are increasingly shaped by political values, yet most research has focused on health, environmental, or economic motives, largely overlooking the role of ideology. While political ideology and political consumerism is well-documented in European contexts, there is limited understanding of how broader ideological orientations influence sustainable food beha

Finished Goods Distribution Network (FGDN) design is an important aspect of Supply Chain Management (SCM), and companies are constantly working towards balancing cost, service level and product quality in the design. At the same time, sustainability has gained an increased focus by stakeholders which has led to both challenges and opportunities in the logistics industry. The FGDN optimization is e

Background In recent years, supply chains have faced major disruptions, including the Covid-19 pandemic, the Suez Canal blockage, and the Russia-Ukraine war, highlighting their vulnerability. As supply chains have become more global and interconnected, the complexity of supply chain networks has increased, leading to them being more exposed to risks. This has resulted in disruptions becoming more

The following thesis investigates the extent to which economic development influences the initiation and consolidation of democracy in Asia. Based on modernization theory and its critiques, the study conducts a quantitative panel data analysis covering 46 Asian countries from 1970 - 2019. Modernization theory suggests that rising income levels, urbanization, education, and social development foste

Bispecifika antikroppar bygger broar mellan immunförsvaret och cancerceller – potentiell ny cancerbehandlingsform Prekliniska försök av en ny bispecifik antikropp aktiverar en av immunförsvarets nyckelspelare mot cancerceller från matstrups- och magsäckscancer. Kroppen är utrustad med sitt eget superförsvar, immunsystemet, som varje dag röjer undan olika hot i vår kropp. Det är ett välutvecklaImmune check inhibitors (ICI) are promising tools in the fight against cancer, increasing the effect of Cytotoxic T Lymphocytes (CTL). However, their efficacy can be limited in tumors with poor CTL infiltration or priming, and strategies enhancing this is of great interest. Dual targeting of CD40 on APCs, and a tumor associated antigen (TAA), is one possible approach, promoting tumor-specific CTL

This thesis explores the architectural potential of compressed wool as a natural material capable of forming complex structures. From the beginning, the project combined two main directions: first, the exploration of natural, growth-based patterns such as differential growth and hyperbolic surfaces, and second, the investigation of material behavior through direct experimentation. These two paths

Mer data och tydligare svar: Avancerad ultraljudsteknik med magnetism för bättre cancerdiagnostik Rektalcancer är ett vanligt förekommande problem som ökar i samhället. För att minska lidande för patienter och eventuell överbehandling finns det vinning i att snabbt och effektivt kunna kartlägga spridningen. Detta arbete har undersökt metoder för att snabbare skapa tydliga bilder av spridningen tiRectal cancer is a common type of cancer, and the escalating prevalence is correlated to the western lifestyle. Most patients will undergo surgery, where the extent of the surgery correlates with the tumor stage. Determining the spread to neighboring lymph nodes is challenging, as certain evaluation requires biopsy of the resected tissue. Therefore, NanoEcho is currently developing a diagnostic to

The recent developments in stochastic and quantum thermodynamics has laid the foundation for developing highly efficient devices that utilizes quantum effects. One such device is a quantum dot heat engine, that consists of one or more quantum dots tunnel coupled to two leads. By tuning the energy levels of the quantum dots appropriately one can obtain a flow of electrons through the quantum dot sy
