Ivanovo State University or IvSU is located in Ivanovo, about 300 km east of Moscow, Russia. The University was founded in 1918; before 1974 was called Ivanovo State Pedagogical Institute.IvSU has accreditation and license from the Russian Ministry of Education. It is a member of Euroasian association of universities and Russian Association of Classical Universities, co-operates with educational institutions of Germany , Sweden , Denmark and China among many others. The training of international students has started in 60's with the programs for the students from socialist countries. In 1982 the separated Department of Russian as a Foreign Language was created in order to prepare international students to study in Russia. It was the first university in the region offering degrees unusual in the Soviet system: economics , law , sociology and applied programming. IvSU has different types of programs from traditional five years specialist degree to four years bachelor's degree and two years master's degree following the modernization of Russian education system and Bologna Process. Also, the university has 10 specialized councils that grant the degree of Kandidat Nauk as well as postgraduate degree of Doktor Nauk in the fields of history, technical science, linguistics, philosophy and economics.

Micro DSC measurements were used to investigate the synergistic effects of temperature and relative humidity on deterioration of parchment. Samples were obtained by exposing new parchments to various temperature and relative humidity atmospheres for increasing times in controlled test chambers. The impact of this accelerated ageing was assessed by measuring the thermodynamic parameters associated with the thermal denaturation of fibrillar collagen: variation of denaturation temperature, T max, indicated changes in collagen thermal stability, increases of DSC peak half-width, ΔT 1/2, revealed greater thermal heterogeneity and structural disorder, whereas parallel decrease of denaturation enthalpy, ΔH, and DSC peak maximum height, Cpex max, measured the loss of fibrillar structure. Deconvolution of DSC denaturation peaks provided a valuable illustration of both the dynamics and the pattern of the deterioration of fibrillar collagen. Impact of temperature and relative humidity on parchment integrity and stability is discussed in terms of their implications for conservation science. © 2011 Elsevier Ltd. All rights reserved.

We discuss a question whether the observed Weinberg angle and Higgs mass are calculable in the formalism based on a construction in which the electroweak gauge group SU(2) × U(1)Y is embedded in the graded Lie group SU(2/1). Here, we follow original works of Ne'eman and Fairlie believing that bosonic fields take their values in the Lie superalgebra and fermionic fields take their values in its representation space. At the same time, our approach differs significantly. The main one is that while for them the gauge symmetry group is SU(2/1), here we consider only symmetries generated by its even subgroup, i.e. symmetries of the standard electroweak model. The reason is that such formalism fixes the quartic Higgs coupling and at the same time removes the sign and statistics problems. The main result is that the presented model predicts values of the Weinberg angle and the Higgs mass correctly up to the two-loop level. Moreover, the model sets the unification scale coinciding with the electroweak scale and automatically describes the fermions correctly with the correct quark and lepton charges. © 2016 World Scientific Publishing Company.

This paper will show that so-called "Newton's law of cooling" that is often used for calculating of heat transfer by convection is actually not a law, but a model of heat exchange (heat transfer). Limits of validity of this law were discovered and will be shown. Moreover, an existing practice of modernizing this law for the purpose of calculating convective heat transfer will be questioned. © 2012 Elsevier Ltd. All rights reserved.

The problems concerning the formation of complexes with proton transfer of β-substituted β,β-fused tetraazaporphyrins in a system dimethyl sulfoxide-chlorobenzene (benzene) are considered. The problems of their structure are discussed. The reactivity of the proton-transfer tetraazaporphyrin complexes in the reaction with metal acetates was studied. The stability of the proton-transfer tetraazaporphyrin complexes depending on the basicity of the environment and the nature of the substituents in the macrocycle is analyzed. © 2013 Pleiades Publishing, Ltd.

Direct calorimetric method was used to determine the heat of reaction of L-valyl-L-valine stepwise dissociation. The standard thermodynamic characteristics of the studied equilibria were established. The results are compared with the corresponding data for related compounds. © 2013 Pleiades Publishing, Ltd.

We study the low energy evolution of coupling constants of the standard model and show that gauge coupling unification can be achieved at the electroweak scale with a suitable normalization. We choose the grand unification group to be the semidirect product of Spin(8) by S3. In this case the three low energy gauge couplings and the two scalar self-couplings are determined in terms of two independent parameters. In particular, it gives a precise prediction for the mass of the Higgs boson. © 2013 Springer-Verlag Berlin Heidelberg and Società Italiana di Fisica.

Protolytic equilibria in aqueous solutions of glycyl-DL-serine, glycyl-DL-threonine, and glycyl-DL-valine are investigated by means of potentiometry and calorimetry. Dissociation constants and heat effects of the above dipeptides are determined. Standard thermodynamic characteristics (pK°, ΔdisG°, ΔdisH°, ΔdisS°) of the investigated equilibria are calculated. The obtained results are compared to corresponding data on relative compounds. © 2016, Pleiades Publishing, Ltd.

The review analyzes the data on the reactivity of β-substituted and β, β-tetrabenzofused tetraaza porphyrins in acid-base interactions in benzene and dimethylsulfoxide with cyclic and acyclic, in the latter case primary, secondary, and tertiary, nitrogen bases. Unusually low rate of the processes was established. The effect of the medium dielectric permittivity, the nature of the base and of the substituents in the tetraaza porphyrin macrocycle on the rate and activation parameters of acid-base interactions are demonstrated. The structure and stability of the tetraaza porphyrin complexes with the proton transfer are discussed. © 2013 Pleiades Publishing, Ltd.

Data characterizing the properties of molding pastes for extrusion of thin-wall articles with complex profiles are presented. It is proposed that parameters such as the deformation ratio, the relaxation period, the power required to break down the coagulation structure, and the flow index be used to characterize the molding properties of the pastes. Pastes with developed plastic properties and strong coagulation structure are recommended for extrusion.

In this work we continue to develop a field-theoretic methodology, which combines the technique of Gaussian equivalent representation for the calculation of functional integrals with the continuous Gaussian thread model of flexible polymers for solving statisticalmechanical problems of polyelectrolyte solutions. We present new analytic expressions for the osmotic pressure, the potential of mean force, and the monomermonomer pair distribution function, and employ them to investigate the structural and thermodynamic quantities of the polyelectrolyte system. We demonstrate the applicability of the method for systems of polyelectrolyte chains in which the monomers interact via a Yukawa-type pair potential. As a specific example, the present work focuses on aqueous solutions of hyaluronic acid with added salts NaCl and CaCl 2. Hyaluronic acid is a high molecular weight linear polysaccharide, which has a multitude of roles in biological tissues. We conclude that the effect of sodium chloride and calcium chloride on the osmotic properties of hyaluronic acid solutions can be accounted for by their contributions to the ionic strength. Nevertheless, the effects of coiling and self-association can be stimulated in solution by added salt. © 2011 Elsevier B.V. All rights reserved.
