Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential. However, clonal plants have revealed similar levels of gene

The human rights regime and the trade regime set obligations on states that may create conflicts that challenge a state’s autonomy for policy and regulatory practices. To deal with these conflicts, we argue that states employ different causal mechanisms from Risse, Ropp and Sikkink’s spiral model when setting their commitments to, and executing compliance with, these regime obligations, and that t

The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions

This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. First, the stray-light suppression method Periodic Shadowing (PS) is implemented in an experimental setup with a high-power high repetition rate laser syste

This thesis investigates how the integration of post-combustion carbon capture (PCC) systems would affect combined heat and power (CHP) plant performance, using DWSIM, an open- source process simulation tool. A case study on a CHP plant in southern Sweden was conducted, with models simulated for both baseline and CCS-integrated operation. DWSIM proved accurate within a relative error of under 3 %

This study investigates whether downside risk, captured through downside beta, is a priced risk factor in the Swedish stock market. Using monthly data from 1990 to 2019, the study sorts portfolios of Swedish stocks into quintiles by downside beta. These portfolios are then evaluated using standard asset pricing models, along with extensions that incorporate low-beta strategies such as the inclusio

As the demand for sustainable and efficient energy systems continues to grow, integrated energy solutions have sparked interest in materials that combine multiple functionalities within a single structure. Rather than serving a single purpose, such materials could store energy, catalyse chemical reactions, and even exhibit optical changes, enabling novel applications in smart devices and material

This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic

Far beyond its innocence, children and child welfare initiatives have emerged as powerful symbols in Indonesian political campaigns. This research focuses on Joko Widodo and Prabowo Subianto, showing how their use of initiatives like Smart Card and Free Lunch Program projected legitimacy and garnered votes during the 2014, 2019, and 2024 elections. It uses two main methods: reflexive thematic anal

To this day, the question of what factors drive economic development and catching-up remains deeply controversial in growth literature. The concept of social capability provides a useful framework to investigate the relationship of the parallel processes of transformation, inclusion, autonomy and accountability with economic performance. Nevertheless, there are few attempts to quantify social capa

This paper investigates the spillover effects of siblings growing up with a brother or sister diagnosed with a chronic disease. I focus on the effect of having a sibling diagnosed with low birth weight on outcomes measuring educational attainment and achievement. The empirical analysis draws on data from the ’NLSY79 Child and Youth Survey’ and I find evidence of a significant negative effect on th

This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. The thesis begins with a literature rev

There is a need to identify leverage points for a broader cultural transformation that addresses the root causes of the nature-climate emergency. Music and art festivals are creative free spaces outside the everyday workings of society that have the potential to plant the seeds of a holistic, sustainable future. I combine prefiguration and the three spheres of transformation in a framework to inve

Pellets are a form of biomass used in highly efficient heating systems. Thus, development of pellet markets could improve energy efficiency, reduce emissions of greenhouse gases, create employment opportunities, increase energy security, and improve air quality. The present research explores the development of the domestic pellet market in Bulgaria. The research’s objectives are to investigate bar
