One of the tasks of system ecology is the study of changes in the abiotic environment as a result of economic activity. Currently, environmental monitoring of low-frequency electromagnetic fields in the abiotic environment of built-over lands is based on the study of the amplitude spectrum of electric-field and magnetic-field intensities. On the basis of the similarity of wave processes the authors theoretically showed the possibility of intensymmetric approach to monitoring and definition of complex intensity of low-frequency electromagnetic field. The authors presented the theoretical and practical justification of the study of the active component of the integrated intensity of the near-field zone of low-frequency source of electromagnetic influence. Determination of the active component of the intensity will help to find the direction of the radiation source and develop the most effective methods of protection. Besides, the conducting of intensymmetric measurements of low-frequency electromagnetic fields will allow proceeding to the evaluation of the total negative impact on human and natural environment.

A quantitative analysis of the heavy metals and benzo(a)pyrene in soil, water and sediments of several lakes was performed in this work. Quantitative analysis was performed by ICP-MS and HPLC technique. The coefficients of variation, which evidence is uneven, were calculated for the heavy metals and B[a]P in soil, water and sediments. Elements which have high concentrations were found. Components which exceeded background concentrations values were identified. The influence of road traffic flows on the background concentrations for heavy metals in soils and sediments of ponds of recreational areas was determined.

The experimental studies on hardness of unfilled polycarbonates and also of filled polycarbonate and polyamide in lateral bending mode of the specified cyclic deformation were made. The influence of technological gap on fatigue properties error was found experimentally. There were investigated the dependence of stress on defomations when lateral bending and the possibility of describing it with linear and exponential laws. Hardness limits of plastics deformations and stresses were obtained.

A promising method of measuring the electric conductivity is discussed in the paper. The possibility to exclude the effect of amplitude noise on the informative component of the output signal is shown. The optimal structure and parameters of a pulse contact transducer are chosen. There was created a model of contact conductivity meter.

The main provisions of thermodynamics at finite time are discused and results of its application to a number of commonly encountered processes are given. It is shown that it is possible to obtain the parameters of the most effective modes after finding the parameters of the process organization, which are appropriate to minimal dissipation.

During creation of obtaining technology of the inorganic acids range of high purity the authors developed information database of the flexible production, including 7 standard hardware modules: chemical cleaning, rectification, desorption, adsorption, absorption, content correction and filtration. The system of computer quality management is developed for analytical monitoring of high purity inorganic acids on the basis of information CALS-technologies.

Respiratory activity of microorganisms is an important indicator of the activated sludge technology allowing to judge biochemical capabilities of active sludge, calculate sewage treatment plants, predict the results of usage of specific technological operations. Tha authors conducted the study of respiratory activity of Kuryanovskaya sludge and active sludge formed in bioreactors operating by various technologies of biological treatment.

The article is about system researches of innovative resources of 165 leading enterprises of chemical and petrochemical industry of Russia within 1995-2012. The developed methodology is for comparative analysis of innovative resources for branches of the chemical and petrochemical complex. Analysis of innovative resources was conducted with the use of indices of innovative financing and production of innovative products, as well as ranking of industries according to the criterion of innovation development.

Steady growth in world energy prices requires finding the optimal conditions for the processes of chemical technology. Results of testing of previously prepared a mathematical model of the process of purification of industrial gases from carbon dioxide. Shows the dependence of the absorption capacity and the amount of absorbed CO2 by the fluid flow. Proved that no need for the use of the liquid flow rate is similar flooding regime of absorber, since at some point the increase of liquid flow ceases to have a significant impact on the overall absorption capacity of the solution. Also shown is the possibility of reducing the flow of solution in industrial environments, which allows to obtain economic benefits from reduced energy consumption on the circulation of the solution and the gas purification process in general. The value of the temperature for maximum rate of chemisorption of carbon dioxide.

The problem of extraction of butanol from aqueous solutions are considered. We propose a method of ultrasonic transformation of the surface layer of a liquid into an aerosol, which allows to increase the efficiency of the separation process, and an assessment of the data of laboratory measurements of the concentration of the components in the original environment and in the condensate.

The problems using of thin clients for operational planning processes.
