In many European countries, it is a political goal that future growth in local travel should be absorbed by sustainable transport modes. Concerns that increased walking and cycling produce more accidents have been countered by the "safety in numbers" (SiN) argument. According to SiN, the more walkers/cyclists there are in a population, the lower their risk. SiN has been demonstrated in cross secti
Fiber composites are widely used for space applications such as antennas, solar panels and spacecraft support structures. This paper presents a combined electromagnetic and acoustic analysis of a triaxial carbon fiber weave structure, designed for ultra lightweight reflector antennas in satellite communication systems. The electromagnetic and acoustic performance of the structure are analyzed over
Simple models are less input demanding and their calibration involves a lower number of parameters, however their general applicability to vast areas must be tested. We analysed if a simple ecosystem model (PRELES) can be applied to estimate carbon and water fluxes of Boreal forests at regional scale. Multi-site (M-S) and site-specific (S-S) calibrations were compared using evapotranspiration (ET)
This paper is focused on implementation challenges related to the integration of sustainable mobility in strategic local/regional land use and transport planning. The work was based on a case study of Stockholm, Sweden, focusing on four current plans and strategies of key importance for sustainable mobility. We identify and discuss implementation challenges related to sustainable mobility using a
Modern society is becoming increasingly dependent on a continuous supply of electricity. In order to maintain the safety and security of society and its citizens, it is therefore necessary that electricity networks are resilient toward disruptions whether caused by natural disasters, sinister attacks, or other. Margin and sensitivity are two crucial aspects of the resilience concept which have so
Purpose: Individuals with tetraplegia depend on alternative interfaces in order to control computers and other electronic equipment. Current interfaces are often limited in the number of available control commands, and may compromise the social identity of an individual due to their undesirable appearance. The purpose of this study was to implement an alternative computer interface, which was full
The rapidly growing interest in photocatalytic systems for direct solar fuel production such as hydrogen generation from water splitting is grounded in the unique opportunity to achieve charge separation in molecular systems provided by electron transfer processes. In general, both photoinduced and catalytic processes involve complicated dynamics that depend on both structural and electronic effec
This article identifies factors which contribute to households’ willingness to pay for improving and protecting a multiple-use water scheme in Ethiopia. It does so through descriptive statistics, a probit model and contingent valuation methods complemented with qualitative data. Estimates suggest farmers’ willingness to pay is based on gender, the prevalence of waterborne disease, the time to coll
This paper presents a novel approach for the elaboration of an integration strategy for controls and computing systems at large particle accelerator based research facilities. The approach is applied in a specific case study conducted at the world-leading neutron science facility European Spallation Source (ESS). First, an introduction to the term 'integration' in the Systems Engineering literatur
OBJECTIVE: Sleep disturbances and alterations of diurnal endocrine rhythms are associated with increased risk of type 2 diabetes (T2D). We previously showed that young men born small for gestational age (SGA) and with increased risk of T2D have elevated fat and decreased glucose oxidation rates during nighttime. In this study, we investigated whether SGA men have an altered diurnal profile of horm
In 2014 the Nordic Council of Ministers initiated a new bioeconomy project: “Test centers for green energy solutions – Biorefineries and Business needs”. The purpose was to strengthen green growth in the area of the bioeconomy by analyzing and mapping the current status of the bioeconomy in the Nordic countries and identify potentials and obstacles, needs and opportunities. Based on this a set of
Conditional knockout mice are commonly used to study the function of specific genes in hematopoiesis. Different promoters that drive Cre expression have been utilized, with the interferon-inducible Mx1-Cre still being the most commonly used “deleter strain” in experimental hematology. However, different pitfalls associated with this system could lead to misinterpretation in functional studies. We
Background and Aims: Small-bowel bleeding is the primary indication for capsule endoscopy (CE). Many experts advocate a "watch-and-wait" policy in negative CE. This meta-analysis examines the odds of rebleeding after negative index CE and the impact on long-term follow-up. Methods: A comprehensive literature search identified articles examining the rebleeding rate after negative CE. Demographic an
Water exchange on Pt(H20)42+ and trans-PtCI2(H20)2 has been studied by means of a new oxygen18 tracing technique. The exchange between a platinum(II) complex and 018-enriched water has been rapidly quenched by addition of excess chlorine, which gives a substitution-inert platinum(IV) complex. The time-dependent oxygen16/oxygen18 distributions of the platinum(II) complexes are obtained from the 195
Under climate change conditions, climatic wildfire danger could also increase in ecosystems not dominated by fires until now. This increasing trend could lead to more area burned in the future. We have developed an algorithm to map new fire-prone areas in Europe and Northern Africa that identifies grid points where a rare fire event is becoming the mean at the end of the 21st century. When applyin
Research has shown that people with psychiatric disabilities who attend a day center rate their satisfaction with daily occupations equally in comparison with non-attendees. The current study investigates which occupations the target group performs and also differences in occupational choices between attendees and non-attendees. Reported occupations were analyzed with content analysis. Day center
