BACKGROUND Nitric oxide is important in vasomotor regulation. Contamination of anaesthetic gases with nitric oxide could affect gas exchange. METHODS We measured oxygenation and nitric oxide concentrations in the inspiratory and expiratory limb of the ventilator circuit in patients about to have cardiac surgery. Measurements were made before surgery when the circulation and respiratory condit...

We calculate the energy of one- and two-dimensional weakly interacting Bose-Bose mixtures analytically in the Bogoliubov approximation and by using the diffusion Monte Carlo technique. We show that in the case of attractive inter- and repulsive intraspecies interactions the energy per particle has a minimum at a finite density corresponding to a liquid state. We derive the Gross-Pitaevskii equa...

The application of ionic liquids as environmentally benign reaction solvents for synthesis and catalysis has received extensive recent attention. In this regard we have developed ionic liquids based on the cheap and readily available components choline chloride (ChCl; HOCH2CH2N(Me)3?Cl) and zinc chloride as alternatives to the more commonly employed alkyl imidazolium-aluminium chloride mixtures...

In this paper we present a fast and accurate solution for skin segmentation of facial images in the JPEG compressed domain, in order to classify faces for further cosmetics applications. Within the increasing of image resolution in the past few years, the requirements for large storage space and fast processing (as developments directly in the compressed domain) became essential. The segmentati...

Abstract This article is the first of three projected IUPAC Technical Reports resulting from Project 2011-037-2-100 (Reference Materials for Phase Equilibrium Studies). The goal this project to select reference systems with critically evaluated property values validation instruments and techniques used in phase equilibrium studies mixtures. report proposes seven liquid–liquid studies, covering ...
