The 3D microstructure around a tin whisker, and its evolution during heat treatment were studied using scanning 3DXRD. The shape of each grain in the sample was reconstructed using a filtered-back-projection algorithm. The local lattice parameters and grain orientations could then be refined, using forward modelling of the diffraction data, with a spatial resolution of 250nm. It was found that the

Background: Assessing disparities in health-related quality of Life (HRQoL) is important as a part of health-related disparities in the society. The aim of this study was to explore HRQoL among 12-year-olds in Sweden in terms of differences between years 2005 and 2009 and disparities related to sociodemographic background. Methods: During the school years 2005 and 2009, a total of 18,325 sixth gra

A highly debatable issue is whether or not a paradigm shift toward the sharing economy could help to address the economic, social and environmental challenges of our time. This article contributes to the academic discussion by exploring the types of value created by sharing organisations and the strategies they use to institutionalise themselves in relation to powerful institutions. The study appl

Oxy-fuel combustion is one of the proposed technologies with the potential to achieve zero CO2 emission. La1−xCaxCo1−yFeyO3−δ (LCCF) perovskites are promising materials with high selectively for oxygen. In this study, the oxygen non-stoichiometry of perovskites LCCF was investigated by means of iodometric titration. LCCF was prepared using the liquid citrate method, and the phase structures were i

A new mean-field theory is developed to treat a binary mixture of nanoparticles imbedded in a polydisperse polymer solution. The theory is based on a many-body polymer-mediated potential of mean force (PMF) between the particles and remains accurate even in the protein regime, where the particles' diameters cannot necessarily be considered large compared to the polymer radius of gyration. As imple

Aims: To investigate to what extent socioeconomic differences in swimming abilities persist among children in the city of Malmö, Sweden, after a community-level swimming intervention programme in public primary schools. Methods: A compulsory swimming education programme was launched in 2014 in second grade (at age 8) in all public primary schools in Malmö, Sweden. Data for the present study on soc

US-based philanthropies have long contributed to environmental conservation through non-repayable donations, but some are now beginning to embrace novel investment strategies that are profit-orientated. From the vantage points of political economy and geopolitics, this article investigates the potential ramifications of this shift in funding for large-scale marine protected areas (LMPAs), which ha

We consider the semiclassical Dirichlet Pauli operator in bounded connected domains in the plane. Rather optimal results have been obtained in previous papers by Ekholm–Kovařík–Portmann and Helffer–Sundqvist for the asymptotics of the ground state energy in the semiclassical limit when the magnetic field has constant sign. In this paper, we focus on the case when the magnetic field changes sign. W

Chemogenetics is the process of genetically expressing a macromolecule receptor capable of modulating the activity of the cell in response to selective chemical ligand. This chapter will cover the chemogenetic technologies that are available to date, focusing on the commonly available engineered or otherwise modified ligand-gated ion channels and G-protein-coupled receptors in the context of neuro

Institutional theory (IT) is a very influential set of approaches in organization studies. There is increasing critique that the set is becoming uninhibited: too broad, dispersed, and confusing. Efforts to rejuvinate the field(s) have led to all-embracing definitions and efforts to account for too much, which makes it difficult to identify what is distinct about the assembly of research. This arti

In academic work on modern British poetry, there is a tacit assumption that any poet belonging to the first rank must needs be a “Modernist”. Consequently, scholars and critics are keen to have poets they admire fit in under the “Modernism” umbrella. That desire has led to an extension of the concept–always notoriously hard to define–to the point of meaninglessness. Proceeding from a conviction th

Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen avaiable for other organisms. It contains a complicated MoFe7S9C(homocitrate) cluster in its active site. Many computational studies with density-functional theory (DFT) of the nitrogenase enzyme have been presented, but they do not show any consensus-they do not even agree where the first four protons should be

The four main findings about the age and abundance structure of the Milky Way bulge based on microlensed dwarf and subgiant stars are: (1) a wide metallicity distribution with distinct peaks at [Fe/H] = -1.09, -0.63, -0.20, +0.12, +0.41; (2) a high fraction of intermediate-age to young stars where at [Fe/H] > 0 more than 35 % are younger than 8 Gyr, (3) several episodes of significant star formati
