The intensive use of nano-sized titanium dioxide (TiO2) particles in many different applications necessitates studies on their risk assessment as there are still open questions on their safe handling and utilization. For reliable risk assessment, the interaction of TiO2 nanoparticles (NP) with biological systems ideally needs to be investigated using physico-chemically uniform and well-characteriz
This work is meant to provide theoretical and empirical elements in order to understand the current situation of Norway which given the chance to be part of the European Union (EU) has rejected it twice. However it does not mean that this European country is totally isolated from the integration process. Since 1960 they are part of the European Free Trade Association (EFTA) organisation founded by
The present article researches the mechanisms suggested for controlling the fulfillment of the EU sustainability criteria for transport biofuels that have been presented in the central legal framework in this area, which is Directive 2009/28/EC. The analysis is extended to the related EU policy documents of a non-binding explanatory and recommendatory character. Judging from the content of Directi
3-Methyl-1,2,3-butanetricarboxylic acid (MBTCA) is a secondary organic aerosol and can be used as a unique emission marker of biogenic emissions of monoterpenes. Seasonal variations and differences in vegetation cover around the world may lead to low atmospheric MBTCA concentrations, in many cases too low to be measured. Hence, an important
The current study aims to computationally evaluate the effect of right upper arm position on the geometric and hemodynamic characteristics of the brachial artery (BA) and cephalic vein (CV) and, furthermore, to present in detail the methodology to characterise morphological and hemodynamical healthy vessels. Ten healthy volunteers were analysed in two configurations, the supine (S) and the prone (
Extracorporeal photopheresis (ECP) is one of the most used and established therapies for steroid-refractory graft-vs-host disease (GvHD), with a good effect to side effect profile. In this review, we present a summary of present literature and provide evidence-based treatment guidelines for ECP in GvHD. The guidelines constitute a consensus statement formed by the Nordic ECP Quality Group represen
In coastal areas, there is increased concern aboutemissions from shipping activities and the associated impacton air quality. We have assessed the ship aerosol propertiesand the contribution to coastal particulate matter (PM) andnitrogen dioxide (NO2) levels by measuring ship plumes inambient conditions at a site in southern Sweden, within a SulfurEmission Control Area. Measurements took place dur
Residential biomass combustion is a significant source of aerosol particles on regional and global scales influencing climate and human health. The main objective of the current study was to investigate the properties of cloud condensation nuclei (CCN) emitted from biomass burning of solid fuels in different cookstoves mostly of relevance to sub- Saharan east Africa. The traditional three-stone fi
This study assessed whether methods for capturing the pedestrian experience of outdoor lighting, previously evaluated in a full‐scale laboratory, were applicable in a real‐world setting. It applied an approach capturing the human response to outdoor lighting in a systematic way, by assessing perception, evaluation and behaviour in the lit environment. The study involved 81 participants from two ag
Background How does genetic liability to suicide attempt (SA), suicide death (SD), major depression (MD), bipolar disorder (BD), schizophrenia (SZ), alcohol use disorder (AUD), and drug use disorder (DUD) impact on risk for SA and SD? Methods In the Swedish general population born 1932-1995 and followed through 2017 (n = 7 661 519), we calculate family genetic risk scores (FGRS) for SA, SD, MD, BD
The Sendai Framework for Disaster Risk Reduction highlights the importance of all-hazard and multi-stakeholder approaches. This requires exchange and integration of risk information across sectorial and administrative borders. This paper focuses on challenges and prerequisites for aggregating risk information from multiple stakeholders in disaster risk management systems. Aggregation is here under
The alternating between dry and wet seasons and the consecutive microbial responses to soil water content in semiarid ecosystems has significant consequences on nitrogen exchanges with the atmosphere. Three field campaigns were carried out in a semi arid sahelian rangeland in Dahra (Ferlo, Senegal), two at the beginning of the wet season in July 2012 and July 2013, and the third one in November 20
If you thought a book about thesis writing would make for wearisome reading, think again! In seven entertaining and enlightening chapters, Mikael Sundström sheds light on the trials and tribulations of academic writing, offering guidance on how to become a doyen of academic disaster – and, more importantly, how to avoid that fate.Prepare to consider your academic writing in a whole new way. Guidin
The literature during 2000–2016 about drying of biofuels from the forest has been reviewed. Biofuels constitute a low-cost energy resource that is likely to continue to increase and the dryers for such products should be simple, robust, and easy to operate. In 1970s and 1980s, rotary dryers and flash dryers were the most common types, and in 1990s, superheated steam (SHS) dryers became common. Mai
Objective: To describe the development and evaluation of the content and face validity and test-retest reliability of a disease-specific questionnaire that measures patient-reported outcomes and experiences for the Swedish National Diabetes Register for adult patients who have type 1 or type 2 diabetes. Methods: In this methodological study, a questionnaire was developed over four phases using an
BACKGROUND: Vascular endothelial dysfunction, accelerated thickening of arterial intima, and changes in ventricular repolarization contribute to increased cardiovascular morbidity in type 1 diabetes (T1D). Although vitamin C has important antioxidant functions and increased oxidative stress is a central mechanism of cardiovascular dysfunction in T1D, the relation between vitamin C and the cardiova
Rhythmic patterning is a widespread structural trait of animal (including human) communication. Concomitantly, a key role of communication is to convey and/or induce emotion. The expression and modulation of emotion is also hypothesized to be a key mechanism for the evolution of rhythmic synchronization in humans. Despite the centrality of both rhythm and emotion to human and nonhuman communicatio
Hard turning offers a cost-effective alternative to traditional grinding, yet the tool wear progression limits the broader industrial adoption. During hard turning, the surface microstructure of AISI 52100 steel transforms into a nanocrystalline structure known as white layer, accompanied by significant surface residual stresses. With optimal cutting conditions, surfaces develop nanocrystalline mi
