The 2005 London terror attacks : An investigation of changes in psychological wellbeing and social capital pre- and post-attacks (2003-07)-A UK panel study

The London public transport suicide bombings, which occurred on 7th July 2005, were described as the worst single terrorist atrocity on British soil to date. Past acts of terrorism have been associated with deterioration in population mental health. They may also negatively impact levels of social capital, which is considered a buffer against poor mental health outcomes. By employing panel data fr

Demonstration of Sn-seeded GaSb homo- and GaAs-GaSb heterostructural nanowires

The particle-assisted epitaxial growth of antimonide-based nanowires has mainly been realized using gold as the seed material. However, the Au-seeded epitaxial growth of antimonide-based nanowires such as GaSb nanowires presents several challenges such as for example direct nucleation issues and crystal structure tuning. Therefore, it is of great importance to understand the role of seed material

Interface dynamics and crystal phase switching in GaAs nanowires

Controlled formation of non-equilibrium crystal structures is one of the most important challenges in crystal growth. Catalytically grown nanowires are ideal systems for studying the fundamental physics of phase selection, and could lead to new electronic applications based on the engineering of crystal phases. Here we image gallium arsenide (GaAs) nanowires during growth as they switch between ph

Silver as Seed-Particle Material for GaAs Nanowires - Dictating Crystal Phase and Growth Direction by Substrate Orientation

Here we investigate the feasibility of silver as seed-particle material to synthesize GaAs nanowires and show that both crystal phase and growth direction can be controlled by choice of substrate orientation. A (111)B substrate orientation can be used to form vertically aligned wurtzite GaAs nanowires and a (100) substrate orientation to form vertically aligned zinc blende GaAs nanowires. A 45-50%

Sn-seeded GaAs nanowires grown by MOVPE

It has previously been reported that in situ formed Sn nanoparticles can successfully initiate GaAs nanowire growth with a self-assembled radial p–n junction composed of a Sn-doped n-type core and a C-doped p-type shell. In this paper, we investigate the effect of fundamental growth parameters on the morphology and crystal structure of Sn-seeded GaAs nanowires. We show that growth can be achieved

"All is well" : Professionals' documentation of social determinants of health in Swedish Child Health Services health records concerning maltreated children - a mixed method approach

Background: Knowledge about social determinants of health has influenced global health strategies, including early childhood interventions. Some psychosocial circumstances - such as poverty, parental mental health problems, abuse and partner violence - increase the risk of child maltreatment and neglect. Healthcare professionals' awareness of psychosocial issues is of special interest, since they

CuInSe2 Quantum Dots Hybrid Hole Transfer Layer for Halide Perovskite Photodetectors

A novel hybrid hole transport layer (HTL) of CuInSe2 quantum dots (QDs)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) was developed to enhance the performance of halide metal perovskite (MAPbI3)-based photodetectors. The introduction of CuInSe2 QDs not only improved the wettability of the PEDOT:PSS HTL for the growth of perovskite crystals but also facilitated the transportat

Unburned Hydro Carbon (HC) estimation using a self-tuned heat release method

An estimation model which uses the gross heat release data and the fuel energy to estimate the total amount of emissions and unburned Hydro Carbon (HC) is developed. Gross heat release data is calculated from a self-tuned heat release method which uses in-cylinder pressure data for computing the energy released during combustion. The method takes all heat and mass losses into account. The method e

Drugs in fall versus non-fall accidents with major trauma – A population-based clinical and medico-legal autopsy study

Background: The main aim of the present population-based study was to compare drugs in fall versus non-fall accidents causing major trauma, including both clinical and medico-legal autopsy data. Methods: All individuals with accidents resulting in major trauma, a new injury severity score (NISS) > 15 or lethal outcome was identified at hospital and/or the Department of Forensic Medicine between 20

Inflammatory potential of diet and risk of lymphoma in the European Prospective Investigation into Cancer and Nutrition

Introduction: Chronic inflammation plays a critical role in lymphomagenesis and several dietary factors seem to be involved its regulation. The aim of the current study was to assess the association between the inflammatory potential of the diet and the risk of lymphoma and its subtypes in the European Investigation into Cancer and Nutrition (EPIC) study. Methods: The analysis included 476,160 sub

Compressive imaging of transient absorption dynamics on the femtosecond timescale

Femtosecond spectroscopy is an important tool used for tracking rapid photoinduced processes in a variety of materials. To spatially map the processes in a sample would substantially expand the method’s capabilities. This is, however, difficult to achieve, due to the necessity of using low-noise detection and maintaining feasible data acquisition time. Here, we demonstrate realization of an imagin

Accuracy and precision of the RABBIT technique

One of the most ubiquitous techniques within attosecond science is the so-called reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). Originally proposed for the characterization of attosecond pulses, it has been successfully applied to the accurate determination of time delays in photoemission. Here, we examine in detail, using numerical simulations, the effect

Gestational hypertension, preeclampsia, and gestational diabetes mellitus after high exposure to perfluoroalkyl substances from drinking water in Ronneby, Sweden

Background: Leakage of fire-fighting foam from an airfield caused contamination of the drinking water supplied to a third of the population in Ronneby, resulting in very high serum levels of predominantly perfluorooctane sulfonate (PFOS) and perfluorohexane sulfonate (PFHxS). The results of studies investigating the association between exposure to perfluorinated alkyl substances (PFAS) and pregnan
