Populärvetenskaplig sammanfattning Arsenik finns överallt i naturen och släpps även ut genom industrier. Det är ett klassiskt gift som färgat historien, men som även använts inom medicin. Arsenik är det enda kemiska cancerogena ämne som ger hudcancer vid förtäring. Det har även använts inom industrin under en lång tid, och deponering av arsenikhaltigt material kommer att orsaka stora miljöproblem.Arsenic is present everywhere in the world. It is found in the bedrock and is discharged by industries. Differents forms of arsenic varies in toxicity, the inorganic form is much more toxic then the organic form. The inorganic form is most common in drinking water and groundwater, meanwhile the inorganic form can occasionally be found in reasonable large quantities in fish and seafood. Today milli

Background: The prevalence of contact allergy in individuals with diabetes and diabetes medical device (MD) users is unknown. Objectives: This study (Part 1 and 2) aims at describing contact allergy prevalences in diabetes MD users. Methods: Adults with type 1 diabetes from two endocrinology departments were patch tested with the Swedish baseline series (SBS) and a MD series. Contact allergies to

Understanding how urban systems and traffic dynamics co-evolve is crucial for advancing sustainable and resilient cities. However, their bidirectional causal relationships remain underexplored due to challenges of simultaneously inferring spatial heterogeneity, temporal variation, and feedback mechanisms. Here we present a spatio-temporal causality framework that bridges correlation and causation

This study investigates the individual usage of the Dublin Core metadata format in three Swedish Subject Based Information Gateways, SAFARI, Svenska miljönätet and Svesök. The authors also present the reader with an overview of the metadata concept and explains in particular the Dublin Core Element Set. The approach to the study is investigation of Dublin Core application from the viewpoint of thr

In the European Union (EU) policymakers are faced with many challenges in national corporate taxation policy from globalization, in particular the increasing cross-border mobility of capital. The EU member countries have become a highly integrated single market and this has meant that trade and investment flows are highly sensitive to corporate tax rates. Corporate tax rates have fallen over the l

Cyclometallation is an important reaction and is essential in organometallic chemistry for the synthesis of stable metal-ligand frameworks and in the development of functional catalytic compounds. Although extensively studied, challenges remain in achieving selective C-H bond activation without the formation of unwanted side products. In this study, a PCP pincer ligand and subsequent cyclopalladat

State-of-the-art laser frequency stabilization is limited by miniscule length changes caused by thermal noise. In this work, a cavity-length-insensitive frequency stabilization scheme is implemented using strong dispersion in a 21 mm long cavity with a europium-ion-doped spacer of yttrium orthosilicate. A number of limiting factors for slow light laser stabilization are evaluated, including the in

Recent research provides new perspectives on large-scale Early Holocene human interaction within Eurasia, based on ancient DNA or lithic technology. But the extent of regional human mobility is not well known. In this study, we combined two different approaches to investigate regional mobility and social networks in southern Scandinavia. We analyzed strontium isotopes in human teeth and regional l

We explored the impact of different radiotherapy (RT) treatment modalities and prescriptions on outcomes for standard risk pediatric medulloblastoma patients (MB-SR). A systematic review and meta-analysis were performed. Primary MB-SR patients, aged 3–21 years treated with cranio-spinal axis and tumor boost RT during 1995–2024 were included. Data on progression-free and overall survival outcomes (

Informal carers in paid work are known as working carers (WKCs). This combination of care and work is particular to them, and their support needs may differ from other informal carers. This exploratory study describes the caregiving-related factors associated with experiencing caregiving as demanding and a decreased ability to work in WKCs. The Swedish National Carer Survey was conducted in a stra

Nickel-based catalysts are the most promising alternative to replace platinum in hydrogen conversion devices in alkaline media. One approach to narrowing the performance gap between Pt and Ni is to fine-tune the nickel surface coverage by (hydr) oxide (NiOxHy) species, which determines its electrocatalytic activity for the hydrogen oxidation (HOR) and hydrogen evolution (HER) reactions. As Ni easi

The skin acts as an effective barrier against the uptake of hazardous chemicals and microorganisms as well as prevention of extensive water loss. These barrier functions are mainly assured by the outermost layer of the skin, the stratum corneum (SC). In conditions such as atopic dermatitis (AD)-a chronic inflammatory skin disease-these barrier functions can become impaired. Although AD is driven b

The aim of this thesis is to understand how migrants perceive their opportunities to access health care, and how underlying factors result in barriers impacting their access to health care and ability to safeguard their health. It does so by answering the research question: How do Venezuelan migrants in Medellín perceive their access to health care? To fulfil the aim and answer the research questi

Urbanisering med växande och tätare städer i kombination med klimatförändring som förväntas kunna ge extremare väder kräver ett smart markanvändande där flera funktioner kan uppfyllas på samma yta. Ett exempel på en multifunktionell anläggning är skelettjordskonstruktioner som har en bärförmåga som hanterar ovanliggande laster, skapar gynnsamma förhållanden för träd och hanterar dagvatten med reniUrbanization with growing and denser cities in combination with climate change that is expected to produce more extreme weather requires a smart land use where several functions can be fulfilled on the same surface. An example of a multifunctional facility is structural soil that have a bearing capacity to handle loads, create favorable conditions for trees and handle stormwater with purification
