An atomistic approach for computing the depolarizing, or internal, electric field in materials with inhomogeneous polarization is developed.Application of the approach for studying the depolarizing fields in technologically Headlights important (Ba _0.7 Sr _0.3 )TiO _3 ferroelectric alloy with temperature gradients has revealed the intrinsic featur
Battling the extreme: lessons learned from weather-induced disasters on electricity distribution networks and climate change adaptation strategies
Electricity infrastructures are critical lifeline systems that are designed to serve with a high degree of reliability the power supply of consumers under normal operating conditions and in case of common failures or expected disturbances.However, many recent weather-induced disasters have brought unprecedented challenges to the electricity network
Do pregnant women want to know the sex of the expected child at routine ultrasound and are they interested in sex selection?
Background: The aim of the study was to investigate if expecting parents wanted to know the sex of the fetus during ultrasound examination and if they had discussed it with the midwife.Another aim was to explore any interest in sex selection.Methods: A longitudinal survey in early and late pregnancy among 2393 women in Sweden.Results: Almost all (9
Lipid motif of a bacterial antigen mediates immune responses via TLR2 signaling.
The cross-talk between the innate Hoody and the adaptive immune system is facilitated by the initial interaction of antigen with dendritic cells.As DCs express a large array of TLRs, evidence has accumulated that engagement of these molecules contributes to the activation of adaptive immunity.We have evaluated the immunostimulatory role of the high
