The vast potential of using sediment adsorbed DNA as a window to past and present biodiversity rely on the ability of solid surfaces to adsorb environmental DNA. However, a comprehensive insight into DNA adsorption at surfaces in general is lacking. Soot and charcoal are carbonaceous materials widespread in the environment where they read-ily can come in contact with extracellular DNA shed from or
Food systems have enormous impacts on people and the planet, with agriculture and food research becoming strategic for many countries. However, the way this research is conducted and the rise of new agri-food technologies have ethical and socio-economic implications. To address these, many scholars are gaining interest in participatory methods, such as citizen science, but are unfamiliar with the
This study explores how Swedish preachers incorporate AI chats such as ChatGPT into sermon preparation. Based on interviews, chat logs, and sermon manuscripts from six priests in the Church of Sweden, the study uses relevance theory to analyse the preachers' prompting and evaluation strategies. The preachers primarily use large language models (LLMs) for brainstorming and inspiration, critically e
The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years
To address the problems of climate change and energy security, Chinese government strived to develop renewable power as an important alternative of conventional electricity. In this paper, the learning curve model is employed to describe the decreasing unit investment cost due to accumulated installed capacity; the technology diffusion model is used to analyze the potential of renewable power. Com
Indonesia has experienced rapid land use change over the last few decades as forests and peatswamps have been cleared for more intensively managed land uses, including oil palm and timber plantations. Fires are the predominant method of clearing and managing land for more intensive uses, and the related emissions affect public health by contributing to regional particulate matter and ozone concent
This study aims to verify the effect of physically removing the outer surface of contaminated concrete on total contents and on potential mobility of pollutants by means of leaching tests. Reclaimed concrete from 3 industrial sites in Sweden were included: A tar impregnated military storage, a military tar track-depot, as well as concrete constructions used for disposing of pesticide production su
The old city of Fez, Morocco, classified as Heritage of Humankind by the UNESCO, is subject to an integrated rehabilitation plan running over 15 years. The plan aims at restoring and preserving the economy, cultural value, and social heritage of the old city. The study follows a system dynamics approach to describe and analyze the rehabilitation plan in order to identify the strengths and defects
Popular Abstract in English Climate migration has become an iconic topic in international climate politics and policy. This work, combining political ecology, critical security studies and post-foundational theories, traces the changes of conflicting discourses across time and space, and assesses the different forms of security they interpellate. While initially attracting attention as a securityThis work seeks to de-naturalise climate-induced migration (CM). Combining political ecology and post-foundational theories, I read CM as a construct that reifies a series of phenomena into an issue to be researched and governed. By assessing the narratives, the knowledge, the logics and imaginaries on which conflicting discourses are built, I analyse the strategies of government they envision. I
This paper describes how four teachers from the same school translate democracy from the curriculum. The interviews describes how the teachers work with the curriculum and what kind of difficulties they confront in the meeting with the students and other teachers. Through qualitative interviews of these teachers, have allowed us to read into their reflections as they explain their reality of the m
Interaction of synthetic TiO2 (anatase) nanoparticles in aqueous suspension at pH 5 was investigated as a function of time in the presence of various organic molecules in terms of adsorption and aggregation behaviour. ζ-potential and average particle diameter were determined with electrophoretic and dynamic light scattering, respectively, while batch adsorption experiments were used to quantify th
Studies on the natural human exposures to fine particulate matter (PM2.5) and their elements composition are practically non-existent in South America. In order to understand the natural exposure of the typical Brazilian population to PM2.5 and their trace element composition, we measured PM2.5 concentrations and collected mass on filters for nine continuous hours during a typical workday of volun
With 450,000 km2 Kobresia (syn. Carex) pygmaea dominated pastures in the eastern Tibetan highlands are the world's largest pastoral alpine ecosystem forming a durable turf cover at 3000–6000 m a.s.l. Kobresia's resilience and competitiveness is based on dwarf habit, predominantly below-ground allocation of photo assimilates, mixture of seed production and clonal growth, and high genetic diversity.
Estuaries are complex environments rich in biodiversity, making it challenging to understand the distribution and occurrence of microplastics due to the multiple variables that can influence the movement of these particles. Based on this, this study evaluated the influence of different environmental aspects on the distribution and transport of microplastics in the surface waters of the Tramandaí R
The Special Section on Post-growth food systems for a just social-ecological transition within planetary boundaries explores post-growth and degrowth approaches that advocate for sufficiency, care, regeneration, and the democratization of food systems. It shows that post-growth food initiatives face multiple structural barriers, including capitalist systems that prioritize profit over ecological a
Stormwater generated during heavy rainfall needs to be managed to prevent flooding and water pollution. In Sweden, drinking water is also used for non-food purposes like irrigation and toilet flushing. To address this, reusing stormwater for non-food purposes through rainwater harvesting can be a solution, which involves collecting and storing rainwater for later use from sources like rooftops, da
Fencing to exclude livestock is one of the effective strategies to passively reshape grassland ecosystem function, yet the dynamics of microbial community construction and their functional traits during restoration remain poorly understood. This study systematically sampled from various microhabitats (phyllosphere, litter, soil) within long-term fenced restoration areas, as well as areas with pers
Efficient and clean production of electrical and mechanical energy for use in industry, transportation and propulsion is currently a concern. The transition from fossil fuels to biofuels involves challenges related to the fuel composition and combustion, as well as methods to increase engine fuel flexibility. One potentially useful tool under development is Plasma Assisted Combustion (PAC), where
Renewable diesel fuels may reduce greenhouse gas emissions and particulate matter compared to fossil diesel, but the toxicity of their combustion products remains unclear. This study assessed pulmonary effects of renewable diesel exhaust particles in female C57BL/6NTac mice after single intratracheal instillation (6, 18, or 54 µg/mouse). Particles were generated from renewable fuels (rapeseed meth
