Both in the social and natural sciences, methodologies have been developed to deal with relatively stable conditions, where findings can be validated based on past experiences. At a time when both social and natural phenomena are rapidly changing, new approaches are urgently needed to produce knowledge for systemic change, inform high-stakes decisions, and enable sustainability transitions in the
The practice of product destruction, whereby retailers or manufacturers dispose of viable consumer products such as unsold goods or customer returns, is an extreme expression of the linearity of our current production-consumption system. This qualitative exploratory study aims to uncover why companies engage in this highly unsustainable and resource-inefficient behaviour and to explore the potenti
Waste incineration bottom ash fine fraction contains a significant amount of aluminium, but previous works have shown that current recovery options based on standard on-step Eddy Current Separation (ECS) have limited efficiency. In this paper, we evaluated the improvement in the efficiency of ECS by using an additional step of crushing and sieving. The efficiency of metallic Al recovery was quanti
The dielectric procperties of MSWI bottom ash as a function of volumetric water content (VWC) are reported in this paper. The objective was to aid the development of microwave based non-invasive emission monitoring and control system for various bottom ash applications. The dielectric measurements were made, on a 1.5-year-old bottom ash, with an electrical network analyzer in microwave range (300
Popular Abstract in Swedish Denna avhandling fokuserar på två av de många faktorer som är av fundamental betydelse både för människors välfärd och för ett lands utveckling dvs. val av dricksvattenkälla och toalettfacilitet. I avhandlingen analyseras olika aspekter av hushållsefterfrågan på dessa två faktorer med hjälp av data från Filippinerna och Bangladesh. Avhandlingen består av fem kapitel, etThis thesis focuses on different aspects of household demand, and the determinants of demand, for water and sanitation related inputs fundamental to the households' well-being, i.e. drinking water and toilet facilities. The thesis consists of five chapters, one introductory chapter and four self-contained, essentially empirical, studies. In chapter two, Women's Health Choices and the Effects on C
Interactions between iron (Fe) and arsenic (As) play a vital role in aquatic and terrestrial ecosystems influencing the reactivity and transport of arsenic. A key aspect is the effect of natural organic matter (NOM) on these interactions, and previous investigations have reported the existence of ternary As-Fe-NOM species. In this study, the reactivity of Fe, from a boreal stream water, towards As
Vägar slits konstant och kräver konstant förbättringar och ombyggnationer. För att möjliggöra detta krävs personer som befinner sig ute på vägarna. Tekniken har gått framåt inom området trafiksäkerhet men skulle behöva förbättras ytterligare om vägarbetare ska vara säkra på sin arbetsplats. Även trafiken har förändrats över åren. Idag finns fler fordon på vägarna än aldrig förr. Bilarna är säkrareRoads are constantly worn down and demands improvements and reconstructions. To make this possible there has to be road workers on the road. Road safety has been improved along the years but can still be improved more. Today there are more vehicles on the road than ever before. The cars are more safe and therefore is encouraging to higher speeds as they are driven together with all safety features
A fundamental precept of geochemistry is that arsenate coordinates at mineral surfaces in a predominately bridging-bidentate fashion. We show that this is incorrect for the model system, arsenate adsorbed at the surface of goethite (alpha-FeOOH), using a combination of XRD, EXAFS, and IR spectroscopic results. We report the crystal structure of pentaamminecobalt(III) arsenate, which consists of mo
The situation for the environment is in many ways dire. However, amidst all the negative environmental developments it is easy to neglect the successes that have actually happened. With the aim of better understanding what factors facilitated such a success this thesis analyses one such case, namely emissions of dioxins and chlorinated waste from the pulp and paper industry in Sweden. Dioxins were
Under perioder då ett företag ökar sitt likvida kapital ovanligt fort, tenderar dessa ofta att använda sig utav extra utdelningar. Detta som ett komplement till ordinarie utdelning med huvudsyfte att bevara nuvarande utdelningspolitik. Dessa kapitaltillskott vilka även benämns som special samt bonusutdelning, har dock effekten av att kunna påverka både värdering och avkastning. Men vilka är egentl
Soil derived dissolved organic matter (DOM) is an important component of the carbon cycle and influences numerous biogeochemical processes, including the formation of mineral-organic associations. DOM ranges in size from small organic molecules to macromolecules and colloidal aggregates. In this study we have used small angle neutron (SANS) and X-ray (SAXS) scattering to characterize the colloidal
Sweden is actively seeking to scale up repair activities as part of its strategy to reduce waste, transition to a circular economy, and achieve zero net emissions by 2045. In the last couple of years, several new policies to promote consumer repairs have been adopted or proposed in Sweden. However, very little is known about the socio-cultural factors that shape people's decision to repair their p
Extending the lifetime of products is seen as a key objective for realising the vision of a Circular Economy. One way to increase the lifespan of products is to enable more repair activities. However, consumers encounter a variety of barriers for repairs, prompting public authorities in Europe and the US to adopt or propose policies in support of consumer repairs. Sweden has recently adopted a cir
BackgroundGraft-contaminating tumor cells correlate with inferior outcome in high-risk neuroblastoma patients undergoing hematopoietic stem cell transplantation and can contribute to relapse. Motivated by the potential therapeutic benefit of tumor cell removal as well as the high prognostic and diagnostic value of isolated circulating tumor cells from stem cell grafts, we established a label-free
The results of the project SSM2019-5225, “Marine 14C levels around the Swedish coast”, financed by the Swedish Radiation Safety Authority (SSM), are presented in the paper “Spatial and temporal variations of 14C in Fucus spp. in Swedish coastal waters” published in the Journal of Environmental Radioactivity. The project SSM2019-5225 focussed on spatial variations in 14C in Fucus spp. samples colle
This report explores what the Nordic countries can do to promote the use of recyclable plastic components in electrical and electronic products, with particular focus on minimising their hazardous chemical component. The report provides an overview of the hazardous additives currently used in the plastic components of EEE, drawing on information available from legislation and supporting studies, r
The influence of environmental policy has been known to move beyond the country or regional contexts in which they have been implemented. Examples in literature include the “California effect” and the “Brussels effect”, showing how the policies adopted in the EU and California influence other jurisdictions. In this paper we study the following: To what extent are companies operating in the United
Plesiosaurs are an iconic group of Mesozoic marine reptiles with an evolutionary history spanning over 140 million years (Ma).1 Their skeletal remains have been discovered worldwide; however, accompanying fossilized soft tissues are exceptionally rare.2 Here, we report a virtually complete plesiosaur from the Lower Jurassic (∼183 Ma)3 Posidonia Shale of Germany that preserves skin traces from arou
Introduction Emerging research indicates that integrated treatment of co-occurring post-traumatic stress disorder (PTSD) and substance use disorder can be effective among adolescents and young people. However, various barriers exist to young people accessing evidence-based treatments. Telehealth offers an opportunity to address these barriers and provide a scalable and accessible alternative to in
