Modelling Possibilities of the Vehicle Movement on Communication Network for Defense and Crisis Management

Abstract: The main aim of this study was to develop a better analytical system of traffic speed. The authors present the calculations of correlation coefficients among all pairs of coefficients to define how much the individual coefficients depend (or not) on each other. The parameters chosen for this study were velocity, gradient, angle of deflection, and road width. The Poisson regression model and negative binomial regression prediction model were applied to analyze and construct prediction models for the dependence of driving speed on different types of roads. The feasibility of two different models was evaluated using SPSS 20 software and the Generalized Linear Models. The study result indicated highly significant coefficients and explained the relationships among all variables. Moreover, constructed Poisson regression model can be used to refine the already worked models of the movement of individual types of passenger cars.

Reactivity and solvatochromism of pentacyanoferrate(II) complexes in diol–water mixtures

Abstract: Rate constants are reported for substitution at the pentacyanoferrate(II) ions [Fe(CN)5L]3−, where L=3,5-dimethylpyridine or 3-cyanopyridine, in binary aqueous mixed solvents containing up to 60vol% 1,2-ethanediol, 1,2-butanediol, methanol or ethanol Trends for diol-containing mixtures are compared with those for monohydroxylic alcohols, and the reactivity pattern for these complexes is compared with those established earlier for base hydrolysis of tris(1,10-phenanthroline)iron(II) and for the aquation of cis-dichloro-bis- (1,2-ethanediamine)cobalt(III) The solvatochromic behaviour of several pentacyanoferrate(II) ions has been established in binary aqueous mixtures containing 1,2-ethanediol, 1,2-butanediol, 1,4-butanediol and 1,2-pentanediol A correlation between reactivity and solvatochromism is presented

Ionic Nature of a Gemini Surfactant at the Air/Water Interface

Abstract: The ionic state of an adsorbed gemini surfactant at the air/water interface was investigated using a combination of surface potential and surface tension data. The combined model was developed and successfully described the experimental data. The results verified the existence of three ionic states of the gemini surfactant in the interfacial zone. Furthermore, the model can quantify the adsorbed concentrations of these species. At low concentrations, the fully dissociated state dominates the adsorption. At high concentrations, the fully associated state dominates, accounting for up to 80% of the total adsorption. In the middle range, the adsorption is dominated by the partially associated state, which has a maximum percentage of 80% at a critical micelle concentration of 0.5. The variation in the ionic state is a unique characteristic of gemini surfactants, which can be the underlying mechanism for their advantages over conventional surfactants.

Improved Miesowicz viscometer

Abstract: The main features of the Miesowicz torsionai viscometer with automatized detection of the plate movement are described. An application of the viscometer to study the anisotropy of viscosity in nematic mixtures RALLE5 and WARSAW4 is shown as an example.
