AbstractThe assessment of the water-physical parameters of soils by indirect geophysical indicators is rather simple and enables the characterization of environmental objects of various volumes. This article presents the results of the determination of kinematic parameters of elastic waves in clay soils with different values of the liquidity index....

AbstractAcoustic and electrical properties determined for frozen saline soils (sand and silt) of massive cryogenic structure with different water contents (three values for each type of soil), salinities (seven values for silt and five for sand) and temperatures (–2, –4, and –6°C) are presented in the paper. A good correlation between the specific ...

AbstractPhase transformations for alloy V-1341 of the Al–Mg–Si system under cooling from quenching temperature are investigated by differential scanning calorimetry and by transmission electron microscopy. An isothermal phase transformation diagram is generated by a design-experiment method. It is shown that the proposed method developed according ...

Relations between the parameters of dynamic crack resistance, impact toughness, sizes of zones of plastic strain in the start region, hardness of the unstrained material, strength characteristics, and tempering temperature of steel 09G2S are determined. The linear regression equations are used to construct mathematical and graphical models for pred...

The structure and properties of a quenched chromium-base alloy are studied after different modes of tempering. The Hollomon parameter is determined and shown to be applicable to alloys, the structure and properties of which after changing the temperature and time of the heat treatment is determined by diffusion of metal atoms in a substitutional so...

A new method for selection of essential peptides applicable for protein detection and quantification analysis in the targeted positive electrospray mass spectrometry has been proposed. It is based on the prediction of the normalized abundance of the mass spectrometric peaks by using a linear regression model. This method has the following a priori ...

On the basis of elementary analysis and 13C NMR spectroscopy, as well as the mean molecular mass and the degree of aromatic content, a structural model of bitumen (coal oil) that satisfies experimental data is formulated. The fragmentary composition of the model is determined: alkyl, naphthene, and aromatic components are present. On the basis of t...

A model of the structure of a highly porous fibrous material is suggested within the framework of which deformation of a setting semifinished item is considered. An algorithm is suggested for calculating the effective thermal conductivity and its components. It accounts for heat transfer through a solid phase and a gas, as well as by radiation. The...

The field of chemoinformatics has developed from different roots, starting in the 1960s. These branches have now merged into a scientific discipline of its own, exchanging ideas and methods across different areas of chemistry. In the last 40 years chemoinformatics has achieved a lot. Without access to the databases in chemistry developed with chemo...
