Popular Abstract in Swedish Mögel i byggnader är ett vanligt problem som kan orsaka en dålig innemiljö och påverka hälsan hos de personer som vistas i byggnaden. Kostnaderna för att åtgärda problemen kan vara omfattande. Att redan vid planeringsstadiet av en byggnad ta hänsyn till risker för mögelväxt kan leda till minskat antal mögelskador i framtiden och ett mer hållbart byggande. Mögelväxt är The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. It is thus crucial that data are available to allow the corr

Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of similar to 650 pb(-1) agree with the predictions of the Standard Model and

Bolivia is a country with a troubling political past, and crammed with political instability and turmoil the Bolivian society inhabits a wide spectrum of cleavages. In this paper we determine that Bolivia is a case of unstable democracy. We use consociational theory and consensus democracy theory to answer why this is the case, by looking at the development Bolivia’s institutional design in order

This paper examines how worries about war affect the political participation of women and men in Ukraine. The analysis is based on secondary data from the seventh wave of the World Values Survey 2017-2020. By constructing linear regressions, I examined whether there is a correlation between the worries about the war and the political activity of women and men in Ukraine. This allowed us to see how

The need for climate change adaptation is widely acknowledged and adaptation projects around the world are proliferating. Despite being one of the key actors for the implementation of adaptation projects, significant knowledge gaps persist regarding the potential maladaptive outcomes of such projects for international non-governmental organizations. This study analyses practitioners' perspecti

This paper investigates the correlation between Sweden's municipal equalization system and economic growth and efficiency for the years 2005 to 2022. This paper uses panel data for all 290 municipalities and a fixed effects model to study the two main parts of Sweden's municipal equalization system: the income equalization system and the cost equalization system. This paper examines multip

Mara–Loita wildebeest migration in Kenya has experienced a dramatic decline since the 1970s, primarily due to habitat fragmentation caused by livestock fencing, agricultural expansion, and urban development. These changes have obstructed seasonal wildebeest movements, leading to disrupted migration routes and increased human-wildlife conflict. In response, four conservation scenarios have been pro

Fragility fractures are a major health concern and accurate estimation of bone strength is important for fracture risk assessment. Finite element (FE) models can provide reliable estimates of femoral bone strength, but traditional approaches typically require three-dimensional imaging and computationally intensive model generation. Previous research has enabled reconstruction of subject-specific F

The dune regions of the Curonian Spit are undergoing a gradual deflation and transformation towards a vegetated surface as a result of extensive forestation and dune stabilization efforts limiting sand input to the dunes. Current dune monitoring in the Spit relies mostly on field levelling, whereas radar interferometry – used extensively in land surface monitoring elsewhere – is not utilized. This

Electrocardiogram (ECG) is an important tool for diagnosing myocardial infarction (MI), but analyzing the ECG signals can sometimes be difficult for physicians. Machine learning could potentially help provide a fast and consistent interpretation of ECG signals. This study aims to evaluate the performance of different machine learning models for classifying MI using ECG data from the PTB-XL dataset

We investigate the validity of thermodynamic uncertainty relations (TURs) in a strongly correlated quantum dot system operating in the Kondo regime. TURs place fundamental bounds on the trade-off between precision and dissipation in non-equilibrium systems, and while these bounds are rigorously proven for classical stochastic dynamics, they are not guaranteed to hold in quantum-coherent, strongly

This thesis investigates the use of several acceleration schemes to improve the performance of the primal-dual hybrid gradient algorithm for linear programming (PDLP), a state-of-the-art first-order method for linear programming (LP). The three main acceleration schemes investigated are: Polyak heavy ball momentum, Nesterov acceleration, and steering vectors selected in a residual momentum directi

Antibiotic resistance is a threat that could result in severe consequences for the public health. The synthesis of new antibiotics is therefore increasingly more important. Sialic acid is a sugar which aids bacterial growth, but the opposite effect could occur if bacteria were prevented from utilizing this sugar. This could be achieved through inhibition of pmSiaT, a protein which transports siali

In this thesis, the required shielding for biologically safe radiation levels during the operation of the shortHIBEAM beamline at the European Spallation Source (ESS) in Lund, Sweden, is presented. The shortHIBEAM beamline is 25 meter long, including a 10- meter magnetically shielded section, a detector and an optional shutter system inside the bunker wall. The shortHIBEAM beamline model was desig

I use the full count data of census year 1910 to examine the intermarriage determinants in Swedish immigrants and the consequences to those who were married to natives compared to their counterparts in endogamy. The results from intermarriage determinants were in line with prior research in general. The results showed that immigrants in exogamy with natives wouldn’t have a high probability o

Amidst a surge in global demand for materials driving the green transition, this thesis investigates how policymakers can best ensure sound environmental performance in the Swedish mining industry following unexpected mine closures. Current Swedish financial assurance mechanisms, intended to operationalize the Polluter Pays Principle, are hampered by unclear criteria and a focus on individual site

The Traditional Knowledge (TK) of Indigenous Peoples and Local Communities (IPLC) plays a crucial role in addressing the biodiversity and climate crises. Yet, market- and state-driven governance of TK continues to assist and enables its exploitation. I investigate the potential of Traditional Knowledge Commons to protect the knowledge and rights of IPLC from violations. Through a multi-case study

Purpose: To investigate whether the U.S.-centred M&A literature translates to the heterogeneous European markets by analysing the impact of economic distress, uncertainty, and relatedness on stock performance. Methodology: This thesis utilises an event study to provide a perspective on immediate M&A announcement impacts. Subsequently, we examine the acquirer’s post-announcement performanc

This thesis aims to address the complex legal challenges related to the responsibility of multinational corporations for human rights violations and environmental harm in global supply chains. Starting from the context of increasing pressure on transnational businesses and the shortcomings of soft law instruments such as the UN Guiding Principles and the OECD Guidelines, the study examines the pot
