The aim of this work was to conduct monitoring and make a regression model of the microbiological air pollution in Volgograd near highways. The work carried out monitoring of microbial air pollution in the residential district of Volgograd near two major highways - first and second longitudinal lines. On the first phase of research the microbial monitoring of air pollution in the residential district of Volgograd was conducted, depending on the proximity to the highway. Number of microbial cells (MC) was evaluated by sedimentation. The assumption is made about the nature of the regression relationship between microbial air pollution and the distance from the highway. Approximating functions and regression coefficients are constructed for the first portion of the longitudinal line at different levels of traffic road. Function is obtained, which allows to calculate the value of microbial contamination of the air, depending on the distance to the road and number of vehicles. In the case of high levels of the microbiological monitoring of the basin air it’s necessary to carry out measures to reduce microbial contamination of the air, for example, regular watering roads, tree planting, vegetative barriers adsorbing pollutants, chemical treatment of disinfectants. The calculation of microbial contamination of the air near a residential building located at a distance of 10 meters from the highway in the central region of Volgograd is conducted using proposed in function prediction of microbial contamination. The developed technique allows us to make calculations without setting up experiments in a specialized microbiology laboratory.

Measurement results of basic characteristics of electronic module based on two specialized analog integrated circuits depending on different square area silicon detectors using source of 239Pu alpha particles is given. Processing of current pulses typically consists to convert them into a voltage by charge sensitive amplifiers and reduce noise by bandpass filters. Earlier for work with avalanche photodiode we have developed, constructed and tested two electronic modules "CRP-MDL-1" and "CRP-MDL-2". During the measurements was investigated spectrometric channel response on exposure to ionizing radiation from a source of alpha particles 239Pu and test input signals, thus we determined basic technical characteristics including energy resolution and noise characteristics. As a result, research found, that the output signal has the following timings: rise time - 1 us (levels of 0.1-0.9), peak time - 1.4 us, fall time - 1.8 us pulse width - 3.5 us. The conversion factor of module working with silicon detector (area of ​​1000 mm2 and a capacity 500 pF) consists about 10.6 mV / fC, or 0.47 V / MeV. Integral nonlinearity of spectrometer path is not worse 0.4% in the range from about 0.1 to 3.2 V. The energy resolution was 89.1 keV line of 5157 keV. The experimental studies revealed that using an external low-noise transistors developed module can be used in the construction of standard radiometric paths. It is appropriate to use the developed design-circuit solutions for implementing 4-channel chip for multi-channel radiometric and spectrometric systems.

A financial market on a stochastic basis with a filtration generated by the binary tree is considered. A plugin simulating failures on this market is constructed. We mean by a failure the following situation on the financial market: when passing from a time moment  to the next one new events arise but discounted price of the fixed type stock does not change. A failure generates the incompleteness of the market (the set of martingale measures of this market is infinite). By modelling of a weak deformation it is possible to reduce the set of martingale measures to a unique measure. Thereby the price of every contingent claim is uniquely determined. This price may be considered as "fair price".

Keywords: Stochastic basis, probability measure, financial market, binary tree, arbitrage free, completeness, weak deformation, martingale measure, plugin.

With the help of so-called deformations (that is of probability measures families on sigma-fields forming a filtration) a notion of deformed martingale is introduced. This notion generalizes the classical concept of martingale with discrete time. We differ two sorts of deformed martingales: deformed martingales of the 1-st and the 2-nd type. Similarly deformed sub- and supermartingales of the 1-st and the 2-nd type are introduced. We prove that infimum of arbitrary family of deformed supermartingales is a supermartingale and that convexe function of deformed martingale is a deformed submartingale. In addition, for deformed martingales of the 2-nd type a telescopic property is obtained.

The nano-catalyst ceria (CeO2), activated by Pt nanoparticles, is known for being prospective and efficient material widely used in catalysis, fuel elements, and sensors. One of the most up-to-date methods of catalysts' reasearch is X-ray absorption spectroscopy (XAS) that is sensitive to the chemical state of catalyst's active centers [1,2]. Using XAS in the fluorescense detection mode at CeL1 line with high precision we studied electronic structure of Pt-activated nanoparticles of ceria at various redox conditions. In order to detect partial X-ray fluorescence yield the emission line CeLγ3 was used, which allowed us to increase spectral resolution. We researched local atomic and electronic structure of the materials under study. Oxygen vacansies were found to appear on the nanoparticles surface of ceria at 5% CO He atmosphere. Theoretical modeling of the obtained spectra at CeL1-edge demonstrated good agreement with experiment.
