Functional channel membranes for drinking water production

Drinking water production utilities rely on, among other processes, different filtration technologies like bank filtration and slow sand filters, as well as pressure, roughing, or rapid gravity filters that, together with low- and high-pressure operating membranes, help to ensure high quality drinking water for millions of customers all over the world. The global market of membrane separation tech

Reduced Prevalence of Severe Intraventricular Hemorrhage in Very Preterm Infants Delivered after Maternal Preeclampsia

Background: Very preterm (VPT) delivery after severe preeclampsia (PE) has been associated with adverse perinatal outcome. It is unclear whether fetal exposure to PE per se modifies the prevalence of neonatal morbidities associated with VPT birth. Objectives: To evaluate neonatal morbidity in VPT infants exposed to maternal PE compared to morbidity in nonexposed VPT infants. Methods: This retrospe

Study of neutron shielding collimators for curved beamlines at the European Spallation Source

The European Spallation Source is being constructed in Lund, Sweden and is planned to be the world's brightest pulsed spallation neutron source for cold and thermal neutron beams (≤ 1 eV). The facility uses a 2 GeV proton beam to produce neutrons from a tungsten target. The neutrons are then moderated in a moderator assembly consisting of both liquid hydrogen and water compartments. Surrounding th

A symphony of stem cells in Vienna - looking to the future

The inaugural 'Symposium for the Next Generation of Stem Cell Research' (SY-Stem) was held on February 22-24 at the Vienna BioCenter in Austria. The meeting focused on having young researchers as speakers, and the program was of an impressively high quality. Here, we summarise key findings from this meeting, which brought together emerging leaders to discuss various topics, including pluripotency,

Update on non-typeable Haemophilus influenzae-mediated disease and vaccine development

Introduction: Non-typeable Haemophilus influenzae (NTHi) has attracted more interest in recent years due to an increased prevalence of infections caused by the pathogen. This upsurge is at least partly ascribed to the introduction of the pneumococcal conjugated vaccines that has resulted in an aetiological shift in NTHi’s favor with respect to upper respiratory tract infections. Moreover, an incre

Detailed chemical compositions of the wide binary HD 80606/80607 : Revised stellar properties and constraints on planet formation

Differences in the elemental abundances of planet-hosting stars in binary systems can give important clues and constraints about planet formation and evolution. In this study we performed a high-precision, differential elemental abundance analysis of a wide binary system, HD 80606/80607, based on high-resolution spectra with high signal-to-noise ratio obtained with Keck/HIRES. HD 80606 is known to

The walking stick in the nineteenth-century city : Conflicting ideals of urban walking

This article reflects on the role of the walking stick in the nineteenth-century city and explores the nature of the criticisms directed at it. The criticism and mocking of certain ways of holding the cane display the deep conflicts within the culture of urban strolling concerning how to take part in it, and who were allowed to do so. By identifying an irritation with canes, we see that there was

Search for Higgs boson decays to beyond-the-Standard-Model light bosons in four-lepton events with the ATLAS detector at √s=13 TeV

A search is conducted for a beyond-the-Standard-Model boson using events where a Higgs boson with mass 125 GeV decays to four leptons (ℓ = e or μ). This decay is presumed to occur via an intermediate state which contains one or two on-shell, promptly decaying bosons: H → ZX/XX → 4ℓ, where X is a new vector boson Zd or pseudoscalar a with mass between 1 and 60 GeV. The search uses pp collision data

Workplace relationships impact self-rated health : A survey of Swedish municipal health care employees

Background: The impact of positive social relationships on the health of municipal employees in the elder care sector in Sweden needs further examination. OBJECTIVE: To explore the association between health and relationships among elderly care employees using a salutogenic perspective. METHOD: Survey of all employees (n = 997) in special housing, home care and Disabled Support and Services in a S

Migration, Transnationalism, and Social Change in Central Asia: Everyday Transnational Lives of Uzbek Migrants in Russia

There is an extensive research that explores the reproduction of transnational communities and relations, with a particular focus on locality, identity and culture. However, the existing literature on transnational migration is largely based on the case studies of immigrant communities living in the United States and Western Europe, while not much has been said about the transnational practices of

Framing Social Interaction : Continuities and Cracks in Goffman's Frame Analysis

This book is about Erving Goffman’s frame analysis as it, on the one hand, was presented in his 1974 book Frame Analysis and, on the other, was actually conducted in a number of preceding substantial analyses of different aspects of social interaction such as face-work, impression management, fun in games, behavior in public places and stigmatization. There was, in other words, a frame analytic co

On stability and conservation properties of (S)epirk integrators in the context of discretized pdes

Exponential integrators are becoming increasingly popular for stiff problems of high dimension due to their attractive property of solving the linear part of the system exactly and hence being A-stable. In practice, however, exponential integrators are implemented using approximation techniques to matrix-vector products involving functions of the matrix exponential (the so-called ϕ-functions) to m

FE simulation and experimental verification of side-flow and burr formation in machining of oxygen-free copper

This article considers the influence of cutting data on burr formation when machining oxygen-free copper in a longitudinal turning operation. Burr formation and side-flow frequently occur in a cutting process, resulting in highly undesirable poor surface integrity and reduced dimensional accuracy of the machined components. Finite Element (FE) simulations of a cutting process were used to simulate
