The results of a molecular dynamics simulation of a 1.1 molal aqueous MgCl2 solution are compared with newly performed x-ray measurements. The structural properties of the solution are evaluated from the scattering data by a model fit to the experimental structure function. The comparison on the basis of fit parameters and partial structure functions shows an overall good agreement between expe...

Propositional Typicality Logic (PTL) is a recently proposed logic, obtained by enriching classical propositional logic with a typicality operator. In spite of the non-monotonic features introduced by the semantics adopted for the typicality operator, the obvious Tarskian definition of entailment for PTL remains monotonic and is therefore not appropriate. We investigate different (semantic) vers...

For ternary polymer-salt-water systems at low polymer concentration (0.5%, w/w), we have experimentally investigated the effect of polymer size on polymer diffusiophoresis (i.e., polymer migration induced by a salt concentration gradient) and salt osmotic diffusion (i.e., salt migration induced by a polymer concentration gradient). Specifically, Rayleigh interferometry was employed to measure t...

conclusions the administration of dextrose saline was associated with a shortened active phase and second stage of labor in vaginally delivered nulliparous women. results of 174 objects enrolled, 150 women delivered vaginally and completed the study. there was a significant difference in the duration of active phase between the groups (ns: 270.20 ± 13.37 minutes; d5ns: 206.67 ± 11.72 minutes) (...

Abstract: There have been lots of studies to control the poor hydration resistance of dolomite refractories one of themost effective solutions has been the addition of magnesia to doloma. Using a co-clinker of magnesia-doloma as astarting material would provide more homogeneity in the properties of the product and has been published recently.On the other hand, addition of iron oxide to doloma h...

abstract physiologists have shown that increased fluids improve skeletal muscle performance in prolonged exercise. typical orders provide for 125 ml of intravenous fluids per hour in patients taking limited oral fluids during labor. our purpose in this study was to determine whether increased intravenous fluids affect the progress oflabor. in a prospective randomized institutional clinical tria...

The surface accessibility of α-bungarotoxin has been investigated by using Gd2L7, a newly designed paramagnetic NMR probe. Signal attenuations induced by Gd2L7 on α-bungarotoxin CαH peaks of H-C HSQC spectra have been analyzed and compared with the ones previously obtained in the presence of GdDTPA-BMA. In spite of the different molecular size and shape, for the two probes a common pathway of a...

A preferential entailment is defined by a binary relation, or “preference relation”. This relation can be either among interpretations or among sets of interpretations. The relation can be also among “states” which are “copies of interpretations”, or “copies of sets of interpretations”. This provides four kinds of preferential entailments. The paper deals mainly with propositional logic, howeve...

The influence of three well-known disaccharides, namely, trehalose, maltose, and sucrose, on some structural and dynamical properties of lysozyme has been investigated by means of molecular dynamics computer simulations in the 37-60 wt % concentration range. The effects of sugars on the protein conformation are found to be relatively weak, in agreement with the preferential hydration of lysozym...

In the natural environment plants are well adapted to minimize damages which only occurs under extreme conditions. In the frame of “physiological window” mild drought induces in plants regulation of water loss and uptake allowing maintenance of their leaf relative water content within the limits where the photosynthetic capacity shows no or little changes. But severe drought induces in plants u...
