Quality indicators for patients with traumatic brain injury in European intensive care units

Background: The aim of this study is to validate a previously published consensus-based quality indicator set for the management of patients with traumatic brain injury (TBI) at intensive care units (ICUs) in Europe and to study its potential for quality measur

Polar ordering of polar octahedra in [C₂N₂H₁₀][VOF₄(H₂O)].

[C2N2H10][VOF4(H2O)] spontaneously crystallises in the polar space group P2(1); strongly distorted V- centred octahedral units form polar chains via head-to-tail H-bonding which, in turn, cooperate via the organic template to form a crystal exhibiting a strong SHG signal. It is suggested that the polar ordering arises from a preference for misalignment of the polar octahedra with the polar chain direction, leading to favourable, asymmetric template - chain H- bonding interactions.</p
