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
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 European Spallation Source (ESS) is a neutron-based research facility under construction in Lund in southern Sweden. The spallation reactions will generate not only the desired neutrons, but also many radioactive byproducts, including 14C. As part of the licensing process, and as recommended by the IAEA, various preoperational studies are being carried out, including mapping the “zero-point” r
This collaborative statement from the International Society for Holter and Noninvasive Electrocardiology/Heart Rhythm Society/European Heart Rhythm Association/Asia-Pacific Heart Rhythm Society describes the current status of mobile health technologies in arrhythmia management. The range of digital medical tools and heart rhythm disorders that they may be applied to and clinical decisions that may
Time-dependent ensemble averages, i.e., trajectory-based averages of some observable, are of importance in many fields of science. A crucial objective when interpreting such data is to fit these averages (for instance, squared displacements) with a function and extract parameters (such as diffusion constants). A commonly overlooked challenge in such function fitting procedures is that fluctuations
The sky view factor (SVF) is an important radiometric parameter for assessing the canopy energy budget of urban areas. There are several methods to determine the SVF observationally. The most common is taking a photo with a digital camera equipped with a fish-eye lens and then converting ratio of sky area to canopy area into SVF. However, most urban canopy models use this variable as derived from
The hydroxyl radical (·OH) is a powerful oxidant that is produced in a wide range of environments via the Fenton reaction (Fe2+ + H2O2 → Fe3+ + ·OH + OH-). The reactants are formed from the reduction of Fe3+ and O2, which may be promoted by organic reductants, such as hydroquinones. The aim of this study was to investigate the extent of ·OH formation in reactions between 2,6-dimethoxyhydroquinone
The majority of all environmental impacts can be linked to our consumption. As real wages increase, so does consumption levels – more holiday trips, more clothing purchases, faster replacement of products for newer versions,etc. This trend poses a threat to the state of our planet. While the Nordic countries are high in the overall rankings of achieving the UN’s Sustainable Development Goals, they
Field-theory simulation by the complex Langevin method offers an alternative to conventional sampling techniques for exploring the forces driving biomolecular liquid–liquid phase separation. Such simulations have recently been used to study several polyampholyte systems. Here, we formulate a field theory corresponding to the hydrophobic/polar (HP) lattice protein model, with finite same-site repul
Discovered more than 40 years ago, microplastics have become a major environmental issue. With increasing global plastic production, microplastics are of growing concern. Landfills have been pinpointed as primary sources of microplastics to surface waters and they have, in fact, been identified and quantified as such. Due to their small size, different polymers and interfering non-plastic material
This article focuses on the role of lay health promoters in the Lindängen initiative, a community-based participatory research (CBPR) programme for health promotion that started 2016 in a low-income neighbourhood in the outskirts of Malmö, southern Sweden. The programme aimed to support equitable health and develop an innovative model for community health promotion. The purpose of this article is
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
This thesis aims at reconstructing events in the solar system, mainly collisional events in the asteroid belt, by searches for extraterrestrial minerals in Paleogene and Middle Ordovician marine sediments on Earth. Recent empirical evidence show that Earth has experienced a few brief periods during the Phanerozoic when the flux of extraterrestrial matter significantly increased. The most prominent
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
Examensarbetet är utfört vid Lunds Tekniska Högskola, avdelningen för Teknisk Geologi i samarbete med Vattenfall Research and Development AB, med syfte att undersöka åldringsfenomen och nedbrytningsprocesser av kraftverkstunnlar i berg. Livslängden för kraftverkstunnlar antas normalt vara mellan 50 och 100 år, varför många kraftverkstunnlar idag uppnått en ålder på mer än 50 år. Kraftverkstunnlar
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 AI Commission prescribed a governance model, namely centralized leadership, to tackle existing digitalization challenges, as outlined in the Roadmap for Sweden at the end of 2024. This research discussed the implications of the Roadmap for Sweden on welfare governance within the Automated Decision-making (ADM) context as interpreted through a Weberian theoretical and methodological framework.
