The kinetics of a ligand exchange in the CuL4/H2Ln system, where H2Ln is the N,N'-alkylen-bis(salicyldimine) tetradentate Schiff base ligand (n = 2 or 3, CH2 groups in the chain length of the amine backbone) was studied spectrophotometrically in DMF solvent with or without triethylamine (NEt3) and H2O at 25 ± 0.1 °C and an ionic strength of 0.01 M NaNO3. The reaction rate was found to be first-...

A thermodynamic simulation of a double effect generator heat exchanger absorption refrigeration cycle using biogas as source of energy has been carried out. The binary mixture considered in the present investigation was NH3 – H2O (Ammonia Water). This simulation was performed in order to investigate the effect of the temperature and pressure of the high temperature generator and the pressure of...

CONTEXT Dyspnea remains a therapeutic challenge, especially in chronic respiratory conditions. Recent studies have shown that the induction of unpleasant dyspnea sensations activates areas in the insular cortex. OBJECTIVE This study was designed to investigate the potential effects of ondansetron, a potent anti-serotonin agent, on induced dyspnea sensation. TYPE OF STUDY A randomized double...

We present a close coupling study of the bending relaxation H2O by collision with He, taking explicitly into account bending–rotation within rigid-bender close-coupling method. A 4D potential energy surface is developed based on large grid ab initio points calculated at coupled-cluster single double triple level theory. The bound states energies He–H2O complex are computed and found to be in ex...

A new strategy for catalytic enantioselective C-acylation to generate α-quaternary-substituted lactams is reported. Ni-catalyzed three-component coupling of lactam enolates, benzonitriles, and aryl halides produces β-imino lactams that then afford β-keto lactams by acid hydrolysis. Use of a readily available Mandyphos-type ligand and addition of LiBr enable the construction of quaternary stereo...

This study attempted to evaluate the relative roles of vessel distensibility and vessel recruitment in the changes in pulmonary blood volume induced by changes in pulmonary intravascular pressure. Pulmonary blood volume was determined by a double-injection indicator-dilution technique in eight anesthetized open-chest dogs with a right and left ventricular bypass which allowed independent contro...

Mechanochemical reaction of solid piracetam with the inorganic salts LiCl and LiBr yields ionic co-crystals which are also co-drugs, characterized by markedly different thermal properties with respect to pure components, also depending on the method for preparation and/or conditions of measurements; single crystal and powder X-ray diffraction at variable temperatures, DSC, TGA, hot stage micros...
