Rusar para-aramid fibres for composite materials for construction applications

The basic properties of fibres manufactured by the company (SVM, Armos, and Rusar), and the areas of their application are reported. The features of production of Rusar fibre used for manufacturing construction materials are presented. __________ Translated from Khimicheskie Volokna, No. 1, pp. 19–21, January–February, 2006.     

Parametric synthesis of multivariable systems based on the solution of the Lyapunov differential equation

A method of parametric synthesis of linear multivariable systems based on the solution of the Lyapunov differential equation is developed. The method makes it possible to take into account the constraints on the parameters of the plant and the regulator, to carry out the synthesis of static and dynamic feedback of the measurement vector, and to simultaneously perform parametric synthesis of the plant and regulator.     

Evolution of the structure of the WWER-1000 reactor vessel from the prototype model to WWER-1200

We discuss the guidelines used in the design of the vessels of WWER-1000 (water-cooled water-moderated) nuclear reactors. The characteristic specific features of the structure of the reactor vessel are discussed, and the subsequent steps of improvement of its design aimed at the increase in its operating safety and designed service life up to 60 years are proposed.     

Basic principles in developing waste-free technology for regeneration of components from spent solutions in synthetic fibre manufacture

Conclusions A methodological approach is given to the development of a technological process for regenerating the components from spent technological solutions. As the object we have examined a very complex system containing an aprotic amide solvent, a monohydric alcohol, water, and a salt component — a chloride of an alkali metal or alkaline earth metal.Requirements have been formulated for heat- or heat-and-mass exchange processes for the preparation of chemical pure object regeneration products. Practical schemes have been examined for closed processes on regenerating components which assure low-waste technology conditions, and recommendations have been given for bringing them into a waste-free technological process.Translated from Khimicheskie Volokna, No. 2, pp. 52–54, March–April, 1989.
