To evaluate the effectiveness of remediation of soils contaminated with petroleum or petroleum products, it is advisable to use the method for determining the integral indicator of biological condition (IPBS) of the soil, calculated on the most informative biological indicators. If, before reclaiming the difference between the IPBS contaminated and uncontaminated (background) soil is less than 10%, it is advisable not to carry out remediation. If the value of IPBS re-cultivated soil and uncontaminated soil IPBS value differ by less than 10%, then reclamation carried out efficiently.

"The aim of this work - analysis of mechanisms of formation of various types of sales management systems, which are used by the Russian entrepreneurial companies. In carrying out this study tested the accuracy of the following hypotheses:
Hypothesis 1: Managers and owners of business enterprises of small and medium-sized understand the critical importance of effective functioning of the sales department of the company to achieve market success.
Hypothesis 2: Managers and owners of business enterprises of small and medium-sized most significant function of sales management consider the function of monitoring the activities of sales personnel.
Hypothesis 3: Managers and owners of small entrepreneurial companies and medium size often organize sales management functions on the basis of the existing market and examples of their experience.
Hypothesis 4: Managers and owners of business enterprises of small and medium-sized believe that one of the main goals of training sessions held in - getting sales staff about how he should conduct their work in the market."
Keywords: The entrepreneurial companies, the effectiveness of the sales department, the function of control, the function of sales management, training.
A method of expanding the bandwidth and improve the performance of the differential voltage divider – attenuator (AT), which have parasitic capacitance on the outputs C01, C02. Wide range of transmission of the AT provided by introducing a compensation circuit C01, C02, which is achieving data quality indicators. Simulation results of desired are shown.
Keywords: a resistive voltage divider, differential attenuator, the parasitic сapacitance load, speed, upper frequency limit, analog-to-digital converters.

The monitoring system of process of stabilization of levels of metal on continuous moulding of preparations machine, constructed useing the observer of a condition is considered. The developed nonlinear observer allows to increase the accuracy of an assessment of levels of the melted metal in the ladle with steel ,industrial ladle and crystallizers, and also makes continuous diagnostics of a condition of glasses of latches. The analysis made on the basis of linearized model, showed the observability and controllability of system on all interval of pouring.
Keywords: Machine of continuous moulding preparations,the controllability, the observability, the observer of a condition, the level of metal
There is considered the problem of structuring indicators of the quality of information-computing systems, including transport. For each quality indicator is determined by the number of corresponding criteria. An algorithm for analysis of subscriber delays.
Keywords: quality, indicator of quality, quality criterion, computer information system of railway transport,subscriber delay
The original modified design of maple shutoff valves for the nuclear power plant, thermal power plant and the main pipeline transport is considered. The new design increases reliability of functioning of a maple latch by pressure self-regulation in a cavity over a maple lock.

Intracellular microinjection - a method of direct introduction of cellular organelles and solutions of substances into living cells. The technique of microinjection into nerve cells by puncturing their processes - axons , which are often surrounded by a dense glial sheath, are described. To puncture the sheath a special injector transmitting microvibrations of ultrasonic frequency on the injection capillary was designed. The results of using the proposed microinjection technique for introducing fluorescent marker in large axons of model object - crayfish ventral nerve cord, to visualize the morphology of axons, were shown.

The authors suggest two approaches to constructing hypotheses about the interactions of proteins on the basis of the results of tracking the changes in their levels during the studied biological process. The first approach is based on the use of machine mining of biological texts, which are freely available on the Internet. The second is related to the execution of database queries on binary protein-protein interactions . To specify the experimental context in obtained protein networks, filtering of the protein entities on the basis of needed ontology from database Gene Ontology was used.
