it is well established that the esophageal distention (ed) leads to gastric relaxation, partly by vago-vagal reflex, but till now, the effect of ed on gastric acid secretion has not been investigated. the aim of this study was to investigate the effect of ed on basal and stimulated gastric acid secretion. methods: adult male wistar rats (200-240 g) were deprived of food but not the water 24 h b...

[1] Key steps leading to the uptake of trace gases into atmospheric cloud ice particles include gas phase diffusion of trace gas molecules toward growing ice crystals and the kinetics of molecular interactions at the ice surfaces. In the case of nitric acid, laboratory studies and airborne field observations indicate uptake in growing ice films and cirrus ice particles above the thermodynamic s...

The paper presents the results of comparative analysis properties coatings based on chromium, nickel and iron borides. alloy obtained in process electron-beam surfacing powder mixture “amorphous boron – 10 wt.% chromium” has best properties. This is explained by structures, fine chromium borides Cr2B complex (Fe, Cr)2B, distributed austenitic matrix. material modified this way a nitric acid sol...

background and purpose: determination of heavy metals in oils is necessary to establish quality standards on a country level. this study aimed to determine of heavy metal contents (cr, ni, as, cd, hg, pb, sb, sn, sr, al) in 12 seed oil samples in iran by inductively coupled plasma-optical emission spectrometry (icp-oes). materials and methods: the concentrations of heavy metal were determined b...

Rigorously standardized laboratory protocols are essential for meaningful comparison of data from multiple sites. Considering that interactions of minerals with organic matrices may vary depending on the material nature, there could be peculiar demands for each material with respect to digestion procedure. Acid digestion procedures were evaluated using different nitric to perchloric acid ratios...
