    Data for: Fast methods of Debye-Hückel limiting slopes calculation and low-temperature extrapolation based on IAPWS equation of state of water

    No full text
    This dataset consists of two parts:1) Tabulated values for the Debye-Hückel limiting slopes (Aphi, AH/(RT), AC/R, AV, AE, AK) obtained by means of IAPWS equations of state for water. They are stored in .csv files.2) Software (IAPWS-DH library) that allows to calculate the Debye-Hückel limiting slopes using IAPWS95, IAPWS-IF97 equations. It also supports some other popular equations set (Archer-1990, Bradley&Pitzer-1979). This computer program is written in ANSI C and is cross-platform; at least MS Windows, GNU/Linux and DOS platforms are supported.The tables were calculated next way:* At T>=273.15: direct usage of IAPWS95 equation.* At T<273.15: usage of high-accurate approximation of IAPWS95 equation by means of 2D orthogonal polynomials (to overcome numerical differentiation accuracy problems).This approach allows to obtain the Debye-Hückel coefficients values for a very low temperature down to about 150 K that can be useful in thermodynamic modelling of very concentrated aqueous solutions using such models as Pitzer, eNRTL or eUNIQUAC models

    Data for: Approximation of thermodynamic functions of aluminosilicates with zeolite-like compositions by Einstein-Planck functions sum

    No full text
    This repository contains the input files (*.txt) for CpFit program. These files are database that contains Einstein-Planck functions sum model parameters and experimental data (thermodynamic properties of individual aluminosilicates) that were used for their optimization. The input files also contain all statistical weights that are required for this optimization. This repository also contains the files (*.csv) with tabulated values. * T is given in K. * Cp (isobaric heat capacity) is given in J/(mol*K). * S (entropy) is given in J/(mol*K). * H-H0 (heat content) is given in J/mol

    Recommendations for Сonstruction of Inclusive Environment at Activities with Participation of People with ASD

    No full text
    Construction of inclusive environment for people with autism, including activities with their participation, is an actual task, but its implementation is complicated by that fact that required measures are not evident. In the article sensory and communicative issues, routines and stereotyped behaviour among people with ASD are discussed. And relevant recommendations for construction of inclusive environment for people with ASD at different activities
