The reinforced composite industry is expanding. This raises the need for more sustainable resource use and waste management. A concept to combat both is circularity, creating a loop between the raw resources and the waste. Two important parts of circularity are recycling and reusing. This thesis presents literature studies on recycling, reuse and end-of-life methods for glass fibre-reinforced plas
Energy cooperatives are seen as a way to achieve energy democracy in both academic and activist circles, with often an implicit expectation that they also contribute to energy justice. These assumptions are increasingly being questioned, often on the grounds of the limited diversity of energy cooperative membership. I conducted semi-structured interviews with four German energy cooperatives in ord
The industrial sector of Sweden used 136 TWh of energy 2022 out of which the agricultural sector used 6.09 TWh. The goal of the country is to become 50% more energy efficient by 2030 compared to 2005. Furthermore, Sweden’s long-term target is to achieve net zero greenhouse gas emissions by 2045. From 2005-2022 the total energy use of the agricultural sector has been reduced by 16% but previous stu
Background: The rise of influencer marketing, fuelled by globalisation and social media popularity, has led to an increased ethically contested promotion of aesthetic surgery by influencers. Existing research has primarily focused on consumers, leaving the influencer perspective and their ethical justifications largely unexplored. Purpose: To explore the ethical justifications of social media infl
The historically rapid growth of modern cities has a tearing effect on our planet, which requires a systematic transformation from linear to circular resource usage and consumption. Scientists and decision makers world-wide propose Circular Cities as a part of the solution, but empirical evidence and theoretical models of their practical implementation is lacking. This study explores the framework
Generally regarded as a sustainable country, Costa Rica faces the future challenge of maintaining their renewable energy performance amidst climate change impacts and the need to integrate intermittent renewables. This thesis explores the opportunities and barriers for Costa Rica to achieve 100% renewable electricity while maintaining energy security, despite its developing nation status. Through
Water scarcity is increasing across different geographical regions of Vietnam. Central drivers of scarcity include population growth and climate change which increase demand and sectoral competition. The legal system is keeping pace to address this trend, but gaps remain in terms of implementation and enforcement. This purpose of this study was to improve the understanding of those gaps via polyce
The decrease in fertility rate has become an increasingly pressing matter worldwide. This research employed the Copenhagen School-rooted theory of securitization in analyzing the discourse on falling fertility rates within South Korea’s defense white papers from 2012 to 2022. In contrast to the mainstream security studies, the argument is that state-specific fertility rates can be considered a thr
A novel approach to reduce the multiple light scattering contribution in planar laser images of atomizing sprays is reported. This new technique, named Structured Laser Illumination Planar Imaging (SLIPI), has been demonstrated in the dense region of a hollow-cone water spray generated in ambient air at 50 bars injection pressure. The idea is based on using an incident laser sheet which is spatial
The emergence of post-genomic approaches that couple chromatin immunoprecipitation (ChIP) assays to high-throughput technique has greatly advanced our ability to investigate epigenetic features associated with normal cell development and disease. Nevertheless, these techniques exhibit some limitations. Firstly, standard protocols usually require millions of cells, thus limiting their application t
Substituting Zn for Cu is known to rapidly quench superconductivity in the doped perovskites but the mechanism behind it is still not clearly understood. Single phase YBa2(Cu1-xZnx)(3)O7-delta (x=0.0 to 0.06) samples were synthesized and characterized using XRD, wet titration, resistivity, and ac susceptibility. Angle-integrated Valence Band Photo emission and Zn K-edge XAFS results clearly show t
We focus on exclusive production of neutral technipion (pi) over tilde (0) in pp collisions at the LHC, i.e. on pp -> pp (pi) over tilde (0) reaction. The dependence of the cross section on parameters of recently proposed vector-like Technicolor model is studied. Characteristic features of the differential distributions are discussed. For not too large technipion masses the diphoton decay channel
Climate change poses a serious challenge to sustainable urban development worldwide. In Sweden, climate change work at the city level emerged in 1996 and has long had a focus on mitigating greenhouse gas emissions. City planners’ “adaptation turn” is recent and still ongoing. This paper presents a meta-evaluation of Swedish municipal adaptation approaches, and how they relate to institutional stru
Stochastic differential equations driven by standard Brownian motion(s) or Lévy processes are by far the most popular models in mathematical finance, but are also frequently used in engineering and science. A key feature of the class of models is that the parameters are easy to interpret for anyone working with ordinary differential equations, making connections between statistics and other scient
The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following exte
A study related to the development and characterization of a new gene delivery system was performed. The approach consists in both the pre-condensation of plasmid DNA with an arginine-based cationic surfactant, arginine-N-lauroyl amide dihydrochloride (ALA), which was found not to be toxic, and the incorporation of the blood protein transferrin (Tf) into the formulations.Two cationic liposome form
BACKGROUND: For a 1-day myocardial perfusion SPECT (MPS) the recommendations for administered activity stated in the EANM guidelines results in an effective dose of up to 16 mSv per patient. Recently, a gamma camera system, based on cadmium zinc telluride (CZT) technology, was introduced. This technique has the potential to reduce the effective dose and scan time compared to the conventional NaI g
The Cone Calorimeter test method has been one of the most used small-scale fire test method for years now and is at present widely spread over the world. In contrast to many other fire test methods, the Cone Calorimeter provides a range of data with sound scientific basis, which allows a wide range of applications. It can be used for modelling and also for enhanced product development. This paper
