The use of antidepressants to treat pediatric mental disorders is contentious as for instancethe FDA black box warning in 2004 has shown. Using cross-sectional data containing ret-rospective mental health diagnostics, I study outcomes of childhood and adolescence mentalhealth on labour supply and overall health in adulthood among those who were and werenot affected by the market entry of fluoxetin
The purpose of the study is to contribute with knowledge of how uncertainty affects decision making processes regarding carbon footprint. This study explores companies' perspectives on what uncertainties they experience, how these uncertainties affect their decision making processes and how the companies handle these uncertainties. The study’s data is generated through semi-structured intervie
There are fundamental unresolved questions about the nature of the long-run interplay between innovation and economic development processes. This study examines technological transitions in Sweden, 1908-2016, using a new literature-based innovation output indicator for the engineering industry, allowing a mixed-methods approach. The results suggest that waves of innovation have taken place during
Elevated arsenic (As) in soil is of public concern due to the carcinogenicity. Phosphorus (P) strongly influences the adsorption, absorption, transport, and transformation of As in the soil and in organisms due to the similarity of the chemical properties of P and As. In soil, P, particularly inorganic P, can release soil-retained As (mostly arsenate) by competing for adsorption sites. In plant an
Background. During the translation of mRNA into polypeptide, elongation factor G (EF-G) catalyzes the translocation of peptidyl-tRNA from the A site to the P site of the ribosome. According to the 'classical' model, EF-G in the GTP-bound form promotes translocation, while hydrolysis of the bound GTP promotes dissociation of the factor from the post-translocation ribosome. According to a more recen
A novel life-cycle assessment (LCA) model has been developed for the investigation of the environmental impact of the choice of material in cable production. In the first application polyolefin based material and PVC material is used. In both cases equivalent fire behaviour is assumed and a fire model is established based on existing fire statistics. This study represents the second full applicati
This article describes how a wheel–rail wear detection parameter based on noise was developed by running a rapid transit train instrumented with microphones in a depot with a small curve radius. This full-scale test made use of previous knowledge gained from lab-scale tests. The lab- and full-scale tests showed that noise could be used as an indicator of wear transition, when normal wear turns int
Noise from the wheel-rail interface is a troublesome side effect when railway vehicles negotiate rail curves. In this laboratory study, two pin-on-disc tribometers were used to simulate the pure sliding process in the wheel-rail contact. The purpose was to investigate the relationships between surface topographies, tribological aspects and the emitted noise. Five different surface topographies man
The coefficient of friction between railway wheels and rails is crucial to the railway adhesion, further greatly affecting railway operation and maintenance. Since the wheel-rail system is an open system, the coefficient of friction is significantly influenced not only by various types of contaminants but also by environmental conditions. This paper conducted a set of pin-on-disc tests measuring t
Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. Understanding the residual stress imparted by machining is an essential aspect of understanding the machining process and overall part quality. Although many investig
We reflect on the decision to abandon the mainstreaming of zero-carbon house building in England, in the context of our paper (Walker et al. 2015) that took this long-standing policy commitment as its case study. We consider this denouement as further evidence of how the exigencies of capital accumulation resist moves towards low-carbon transition. We reflect on what it reveals about the relation
We consider distributed control of double-integrator networks, where agents are subject to stochastic disturbances. We study performance of such networks in terms of coherence, defined through an H2 norm metric that represents the variance of nodal state fluctuations. Specifically, we address known performance limitations of the standard consensus protocol, which cause this variance to scale unbou
Parents are assumed to play a crucial role in the socioeconomic attainment of children. Through investments of both time and resources, they promote the ability, human capital, networks, and motivation of their children to advance socially, or at least to maintain their social position. Consequently, losing a parent in childhood could be detrimental to adult socioeconomic outcomes. We use full-co
Ett viktigt mål för samhället, särskilt för utbildningssystemen, är att vi människor blirbättre på att få syn på växter och på deras betydelse i ekosystemen. Vi behöver över-vinna vad som benämns ‘växtblindhet’. I denna artikel föreslår vi att variationsteoriär en bra utgångspunkt i utbildning och utvärdering av växtidentifiering inom högreutbildning.

We report on the use of multilayer Laue lenses to focus the intense X-ray Free Electron Laser (XFEL) beam at the European XFEL to a spot size of a few tens of nanometers. We present the procedure to align and characterize these lenses and discuss challenges working with the pulse trains from this unique X-ray source.
