  • Methodology to evaluate the feasibility and effectiveness of remediation of soils contaminated by oil and oil products, the biological indicators

    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.

  • Stability of the ordinary chernozem to the combined contamination with lead and the electromagnetic field

    The article discusses the stability of the chernozem biological properties in the combined pollution of lead and an alternating magnetic field. Soil parameters such as the activity of catalase and dehydrogenase, soil biomass, soil phytotoxicity are considered. The main contribution to the change in the biological properties of the soil in the combined pollution by lead and an alternating magnetic field makes lead pollution. The contamination alternating magnetic field with a high level of induction (3000 mkTl) over only reduces the amount of lead pollution of soil biomass, but increases the activity of soil enzymes. At a lower level of induction (300-1500 mkTl) with combined pollution increases the activity of enzymes and biomass is virtually identical to the activity only if contaminated with lead. Phytotoxicity indicators of soil pollution with lead and an alternating magnetic field induction of 300 mkTl did not differ from those of soil contamination only lead, but with an increase in the level of induction to the 1500-3000 mkTl phytotoxicity indicators declined in comparison with the lead pollution at 18-27%.

  • Use of Space Facilities for Positioning during Air and Space Information Processing

    Photometric principles of measurements have found a wide recognition and a wide application in different fields of human activity. It is stipulated by the introduction of photogrammetric works of new technology for obtaining primary information about the locality. At present for obtaining high quality and highly exact airophotographic data digital wide format photographic cameras are used and photogrammetric processing of digital pictures is carried out at special digital photogrammetric work stations.
    A great importance is attached to photogrammetric methods during the monitoring of lands for information providing of state realty cadastre. At present land state monitoring is a modern technical trend to provide this cadastre with the necessary graphic and digital documents.
    Photographing of small territories (dacha settlements, agricultural buildings etc.), when the scale of airophotography is ten or more times less than the scale of map-making, is quite possible because the object can be photographed on two pictures that is to be located on one stereo pair. This article is devoted to photogrammetric processing of a single stereo pair. At this space facilities for positioning (GLONASS, GPS) secure the coordinates and altitudes of points of photographic. When space signals are properly synchronized with the work of the photograph camera shutter and careful determination of the elements of adjustment of space antenna to the relative centre of projection (s) of camera is carried out the coordinates of projection centres can be used as supporting geodetic points.
    Point realization of the above-mentioned terms allows to decrease the number of supporting points necessary for outside orientation of model to one. It should be located at the end of stereo pair opposite its middle. While designing redundant supporting points (for control and improvement of exactness) they should be located in the corners of stereo pair.

  • Magnetic properties of multiferroics BiFeO3, (BiLa)FeO3 and (BiNd)FeO3 electrets formed by corona discharge

    Recently, BiFeO3  multiferroics have drawn a great deal of attention due to their superior ferroelectric properties in epitaxial thin film form in comparison to counterpart bulk single crystals or ceramics. In this work we present the results on magnetic properties of multiferroic ultrathin films (30-300 nm) of BiFeO3, (BiLa)FeO3 and  (BiNd)FeO3  obtained by sputtering in transverse high frequency discharge, vacuum laser oblation and metalorganic chemical vapour deposition  on monocrystalline  substrates of (001) SrTiO3, (100) MgO and  (100) Al2O3. The concentration of Bi, La и Nd in dodecahedral sublattices was varied. A novel effect of treatment of multiferroic films in a negative corona discharge has been investigated. It is demonstrated that the magnetisation may be increased by up to 35%  whilst the change in    is not noticeable. This effect does not depend on neither film composition no technological method.
