In the present study, the effect of setting high airway pressure release ventilation (APRV) pressure guided by an expiratory inflection point of pressure-volume (PV) curve following lung recruitment maneuver (RM) on oxygen delivery (DO2) in canine models of severe acute respiratory distress syndrome (ARDS) was examined. Canine models of severe ARDS were established by intravenous injection of o...

The title compound, [Fe3(C5H5)3(C15H12OP)] H2O or Fc3PO H2O, was obtained as red crystals from the Friedel±Crafts alkylation reaction of PCl3 and ferrocene. Torsion angles (O PÐCÐFe/C) range fromÿ45.39 (9) toÿ56.11 (14) . The structure is stabilized by intermolecular hydrogen bonds [H O = 2.10 (3) and 2.00 (4) AÊ ], forming dimeric structures between pairs of O PFc3 and water molecules. A theor...

A novel Schiff base, ethyl 4-[(E)-(2-hydroxy-4-methoxyphenyl)methylene-amino]benzoate (HL), was prepared and structurally characterized on the basis of elemental analyses, (1)H NMR, (13)C NMR, UV-Vis and IR spectral data. Six new copper(II) complexes, [Cu(L)(NO3)(H2O)2] (1), [Cu(L)2] (2), [Cu(L)(OAc)] (3), [Cu2 (L)2Cl2(H2O)4] (4), [Cu(L)(ClO4)(H2O)] (5) and [Cu2(L2S)(ClO4)(H2O)]ClO4·H2O (6) hav...

Investigating the impact of microhydration on excited-states and electronic excitation properties biomolecules has remained one important yet challenging aspects science because complexity developing models. However, with advent computational chemistry methods such as TD-DFT, many useful insights about energy excited-state nature can be explored. Accordingly, in our study, we have incorporated ...

In this pioneering research, mononuclear coordination complexes and polymers were obtained using the conformationally flexible ditopic ligand 4,4?-diaminodiphenylethane different metal salts (nitrates, sulfates, tetrafluoroborates perchlorates). Seven new products, including [Cd(2,2?-bpy)3](ClO4)2](dadpe)(4,4?-bpy) (1), [Ni(dadpe)2(H2O)4](SO4).H2O (2), one-dimensional {[Zn(NO3)(dadpe)(dmf)2](NO...

Nanofluid, the fluid suspensions of a metallic nanoparticle, became coolant that is used when promising enhancement in heat transfer required. In current study, characteristics flow and are numerically investigated using different nanofluids (Al2O3–H2O, TiO2–H2O, SiO2–H2O) micro-channel sink (MCHS) configurations (rectangular, triangular, trapezoidal, circular). this numerical investigation, ef...

As part of a study to investigate the factors influencing the development of new, more effective metal-complex-based positron emission tomography (PET) imaging agents, the distorted octahedral complex, [GaCl(L)]⋅2 H2O has been prepared by reaction of 1-benzyl-1,4,7-triazacyclononane-4,7-dicarboxylic acid hydrochloride (H2L⋅HCl) with Ga(NO3)3⋅9 H2O, which is a convenient source of Ga(III) for re...

A one-dimensional chemistry model is applied to study the stable hydrogen (D) and stable oxygen isotope (17O, 18O) composition of water vapour in stratosphere and mesosphere. In the troposphere, this isotope composition is determined by “physical” fractionation effects, that are phase changes (e.g. during cloud formation), diffusion processes (e.g. during evaporation from the ocean), and mixing...
