Textile industry is an important source of water contamination. Some of the organic contaminants cannot be eliminated by nature in a reasonable period. Heterogeneous catalytic wet air oxidation is one of the most effective methods to purify wastewater with organic contaminants. In this work, catalysts based on copper…
Vinyl functionalized poly (ε-caprolactone) with molar mass ranging from 500–5000 Da were synthesized by ring opening polymerization and further photopolymerized. One-step synthesis and functionalization is achieved based on ring opening polymerization (ROP). Hydroxyl butyl vinyl ether (HBVE) was employed to play the r…
In this article authors examine the question of watt losses in polarization of dielectrics and their influence on dielectric properties of insulation which has a complex structure. In the article there are some graphs of quantitative and qualitative dependence of some characteristics from temperature for performance m…
Consolidation is the general tendency of the banking industry development. Bank extension promotes the increase of banking system stability. It is especially urgent in the conditions of the global crisis of liquidity and mortgage crisis which decreased abilities of Russian banks in raising funds for financial creditin…
The unit of FEM package ACELAN for composite materials problems solving is developed. Effective properties of piezocomposite materials (porous ceramics) on the basis of equivalence of modal properties of several representative volumes of composite and respected anisotropic solid are determined.
The reduction of power consumption of watering by the raingun with using of the lowpressured spraynozzles was investigated. The optimum distance between the spraynozzles on the pipeline under the various pressure meanings, the diameter of the outlet of the spraynozzle and the height of its installation were reckoned o…
Subject domain's Combine header part preliminary adjustment fuzzy expert knowledge representation some aspects are considered. Subject domain's offered model forms a basis of base of knowledge еxpert system on technological service of combines.
Complex estimate of effective labour leaders and specialists of business is given, taking into account both qualitive (the result of labour, quality, qualification) and quantative, which are characterized for financial-economical activity enterprise.
A relation between surface free energy (σMHV) and Meyer’s lines cut-values has been established using Vickers microhardness (MHV) method and empirical physical laws. This relation allows the calculation of σMHV only from MHV data. The parameters required are Meyer’s lines cut-values and the mean value of diagonal leng…
In this paper, meso-2,3-dimercaptosuccinic acid-Ce(IV) redox couple is used for crosslinking polymerization of acrylamide (AAm) with N,N′-methylene bis(acrylamide) (MBAA) in acid aqueous medium. We have investigated the effects of crosslinker ratio, acid concentration and the molar ratio of AAm/Ce(IV) on the swelling…
В работе найдены в явном виде экстремальные функции для широкого класса функционалов над пространством Харди H 1 .
The macroprocess's decomposition of the combine exploitation is carried out. The indexes and the process's «technical diagnosis» effectiveness and efficiency defining method are offered. The offering method's practical using data is adduced.
The realization of the personal approach to the student is the basic principle in organizing the educational process with the help of modern pedagogical technologies. The concerned technologies help to create conditions for students to reveal their personality traits in the process of Humane Education in college.
Scientific and practical foundations of formation and functioning of regional systems of educational quality control as constituent parts of the national system are reviewed. The experience of the Rostov Region in independent evaluation and informational support of the data pertaining to quality of regional education…
We develop auralization algorithms for computer simulation of sounding of audio files in a certain hall. By using the Ray Tracing Method there is formed the impulse room response. The audible sound is constructed as a convolution of the initial signal with this impulse response. The computational realization is based…

Article is devoted to research of process of centrifugal processing. Theoretical models are developed for definition of an average arithmetic deviation of a structure of the established roughness, depth of the strengthened layer and a degree of hardening. The technique of designing of technological processes of centri…
Process of formation of acoustic performances in cabins of jib cranes in-process surveyed. Dependences of formation of noise in cabins from external sources of an aerodynamic noise are detected and on the basis of it possible ways of drop of levels of a sound pressure on workplaces of crane operators.
The article is devoted to the philosophical aspects of the problem strategy of management organization, which bank human potential is conceptions; inculcate new technology and experience advanced; to the complex plane strategy of the suppose effectual work organization that are gain prime result of an competition.
In operation influence of vibration of elements of a protection of a cabin of the bridge crane on formation of structural noise is considered. Having applied a method of an energy balance expressions of a vibration speed are obtained depending on an entered vibration power of external sources. Possible ways of drop of…
