A new transport property, the self-exchange velocity (SEV) of neighbouring unlike ions, has been evaluated from molecular dynamics simulations of molten LiCl, RbCl and LiRbCl2 at 1100 K and the mixture at 750 K. From the increase of the SEV's in the order Rb+ (pure sa l t )<Li+ (mixture) < Rb+(mixture) < Li+(pure salt), it is conjectured that there is a strong correlation between the SEV's and ...

Kaur, Baljeet S., Rodica Ouatu-Lascar, M. Bishr Omary, and George Triadafilopoulos. Bile salts induce or blunt cell proliferation in Barrett’s esophagus in an aciddependent fashion. Am J Physiol Gastrointest Liver Physiol 278: G1000–G1009, 2000.— Barrett’s esophagus (BE) results from acid and bile reflux and predisposes to cancer. We investigated the effect of bile salts, with or without acid, ...

Garlic and salt spice is widely used in Brazilian cookery, but it has a high sodium content; as high sodium intake has been strongly correlated to the incidence of chronic diseases. This study aimed to develop a garlic and salt spice with reduced sodium intake. Sensory evaluation was conducted by applying the spices to cooked rice. First, the optimal concentration of spice added during rice pre...

Application of solutions of each of the alkali halides to the tip of a labellar sensillum of the blowfly elicited a repetitive neural discharge from the salt receptor. The records were qualitatively similar to those for NaCl. For each of the alkali chlorides and sodium halides, the shapes of the curves of the response of the salt receptor as a function of concentration were similar to that for ...

When used as a negative-tone electron-beam resist, hydrogen silsesquioxane HSQ is typically developed in an aqueous alkali solution such as tetramethyl ammonium hydroxide. This development process results in low contrast. In this work, the authors instead used a mixture of salt and alkali to significantly increase the contrast of HSQ. Contrast values as high as 10 in a 115-nm-thick resist were ...

In this study, TiO2 nanoparticles (average particle size 16 nm) were successfully produced in molten salt phase and were showed to significantly enhance the specific heat capacity of a binary eutectic mixture of sodium and potassium nitrate (60/40) by 5.4 % at 390 °C and 7.5 % at 445 °C for 3.0 wt% of precursors used. The objective of this research was to develop a cost-effective alternate meth...

Barrett's esophagus (BE) results from acid and bile reflux and predisposes to cancer. We investigated the effect of bile salts, with or without acid, on cell proliferation in BE and assessed mechanism(s) involved. To mimic physiological conditions, biopsies of esophagus, BE, and duodenum were exposed to a bile salt mixture, either continuously or as a 1-h pulse, and were compared with control m...

The modification methylase of Escherichia coli B has been purified to apparent homogeneity. The enzyme can exist in several forms, each possess;ng two nonidentical polypeptides, /3 and y, of molecular weights of 60,000 and 55,000, respectively. Freshly isolated enzyme has the structure plyI, but upon storage at neutral pH and low salt, it disproportionates, producing another form, fl3~1. Treatm...

We present a theoretical description of the effect of polyvalent ions on the interaction between titratable macroions. The model system consists of two point-like macroions with dissociable sites, immersed in an asymmetric ionic mixture of monovalent and polyvalent salts. We formulate a dressed ion strong coupling theory, based on the decomposition of the asymmetric ionic mixture into a weakly ...

Dicamba can be included in weed management programs for Brazilian agricultural crops, such as Conyza spp. and Amaranthus spp., it is essential to implement good practices that include salts with low volatility levels appropriate associations maintain at acceptable levels. The objective of this study was evaluate the volatilization dicamba diglycolamine (DGA) salt associated different glyphosate...
