The solubility of quartz in H2O-NaCl solutions was measured at 2, 4.35, 10 and 15 kbar and 500–900°C, and at NaCl concentrations up to halite saturation, usually greater than 75 wt.%. Quartz solubility was also measured in CO2-H2O solutions at 10 kbar and 800°C. Solubilities were determined by weight loss of ground and polished quartz crystal fragments which were equilibrated with solutions in ...

In rodents, at least two transduction mechanisms are involved in salt taste: 1) the sodium-selective epithelial sodium channel, blocked by topical amiloride administration, and 2) one or more amiloride-insensitive cation-nonselective pathways. Whereas electrophysiological evidence from the chorda tympani nerve (CT) has implicated the transient receptor potential vanilloid-1 (TRPV1) channel as a...

1 The regulation of the benzamil (Bz)-insensitive salt taste receptor was 2 investigated by intracellular Ca ([Ca]i), protein kinase C (PKC) and the Ca3 dependent serine-threonine phosphatase, calcineurin (PP2B), by monitoring chorda 4 tympani taste nerve responses to 0.1M NaCl solutions containing Bz (5x10 M) and 5 resiniferatoxin (RTX; 0-10x10 M) in Sprague-Dawley rats and in wildtype (WT) an...

The study of the carbonate cements in the Permian-Triassic Dalan-Kangan formations resulted in the identification of five stages of calcite and dolomite cementation, which completely or partially occluded pores. Cement types appear to be early isopachous calcite (i; C1-non-luminescence), equant (ii; C2-dull CL), fairly coarse secondary dolomite rhombs (iii; C3-zoning red CL), coarse sparry calc...

Using the squid giant axon, we analyzed biochemically the molecular organization of the axonal cytoskeleton underlying the axolemma (subaxolemmal cytoskeleton). The preparation enriched in the subaxolemmal cytoskeleton was obtained by squeezing out the central part of the axoplasm using a roller. The electrophoretic banding pattern of the subaxolemmal cytoskeleton was characterized by large amo...

Latent heat storage units for refrigeration processes are promising as alternatives to water/glycol-based due their significantly higher energy densities, which would lead more compact and potentially cost-effective storages. In this study, important thermophysical properties of five phase change material (PCM) candidates determined in the temperature range between ?22 ?35 °C compatibility with...

This work presents a surface analytical study of the corrosion inhibitor 2-phenylimidazole (2PhI) adsorbed on Cu from 3 wt.% NaCl solution. X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were used to investigate phenomena. Various XPS experiments performed, i.e., survey- angle-resolved high-resolution spectra measurements, gas cluster beam s...

Responses of renal nerve activity and urinary Na+ and Cl- excretion were examined in chronically instrumented conscious dogs through feedings of boiled rice with or without NaCl. The boiled rice (20 g/kg body wt) without NaCl did not influence plasma Na+ and Cl- concentrations, renal nerve activity, or urinary Na+ excretion but decreased urinary Cl- excretion. On the other hand, boiled rice con...

In Senegal, tomato (Solanum lycopersicum L.) cultivation is affected by salinity in many agro-ecological zones. The selection of salt tolerant varieties would be an alternative solution to enhance the production. Thus, germination and growth are studied under axenic conditions for five subjected increasing concentrations NaCl [0, 35, 70 105 mM], supplemented MS/2 medium 30 days. results reveal ...

Abstract DC magnetron sputtering was used to deposit titanium (Ti), nitride (TiN), and Ti/TiN multilayer coatings on Ti6Al4V alloy substrates. The have 1, 4, 10, 16, 32 modulation periods respectively. SEM were analyze the surface cross-sectional micro-features of coatings. Electrochemical tests carried out 3.5 wt% NaCl solution at room temperature. resistance coating reaches maximum value, whi...
