Many-body effects were examined in a series of molecular dynamics computer simulations on the ionic aqueous clusters Na+ (H,O), (n = 4,5,6,14) and Cl(H,O), (n = 4,5,6,7,8,14). Two potential models were used in the simulations. In one model (TIP4P) the potential was pairwise additive, while in the second model (SPCE/POL) the many body effects were explicitly included through a self-consistent po...

Abstract Windshield glasses of Maruti Alto 800 (A800), Hyundai i20 (H20), and Suzuki Eeco (SE) are taken from an automotive repair shop for investigating their physical, optical, mechanical properties to check durability. These amorphous, which is confirmed by X-ray diffraction (XRD). Energy dispersive spectroscopy confirms that the windshield contain SiO 2 , Na O, MgO, CaO, Al O 3 K in variabl...

Inelastic incoherent neutron scattering (IINS) spectra and neutron powder diffraction (NPD) patterns, registered for [Co(H20 ) 6](C104)2 at 18 270 K and for [Mn(H20 )6](BF4)2 at 18 230 K, provided evidence that these crystals possess three solid phases in these ranges of temperatures. In both compounds the phase transition occurring at T C3 is connected with a change of the crystal structure, a...

In an earlier paper2 we have reported results demonstrating that changing the concentrations of the carbon dioxide and oxygen with which the bloods of sheep and goats are equilibrated has a measurable effect on the total osmotic pressure of the true plasma. At constant oxygenation the osmotic pressure of the true plasma is increased 0.9 milliosmoles/Kg H20 for each millimole of C02/Kg H20 added...

Muscovite granite (13.8% muscovite, 4.8% normafive corundum) was reacted, with varying percentages of H20, in cold-seal vessels at 2 kbar and in piston-cylinder apparatus between 10 and 35 kbar. The diagrams illustrating melting/crystallization relationships are: P-T sections with both excess H20 and with no H:O added (0.66% H20 in rock); T-X•2o sections at 15 kbar and 25 kbar showing H:O-under...

Indole-3-acetic Acid, LAA-Oxidase, Peroxidase Formation of H20 2 in the course of peroxidase catalyzed IAA metabolism was measured using the peroxide-dependent decarboxylation of [14C]glyoxylate and the oxidation of phenolic substrates giving rise to fluorescent products in IAA/HRP systems. The results agree with the recent concept of IAA metabolism which includes the formation of H20 2 in the ...

The purpose of this study was to investigate if myogenic responses of isolated coronary arterioles were dependent on an intact, functional endothelium. Arterioles were located in situ by intracoronary perfusion with india ink-gelatin solution and then dissected and cannulated at both ends with glass micropipettes. Intraluminal pressure was initially set at 60 cm H20; then the pressure was alter...

The transport of water in silicate melts is examined from a theoretical point of view, taking into account the presence of both H20 and OH species. It was assumed that only H20 molecules may diffuse and that a constitutive relationship between the number density nH 0 of H20 molecules and the total water content (n:E) exists such that nH,o = g(n:E) . This is related to dissociation or to chemica...
