Titov E. V., Nurbatyrova L. N., Ovechkina Y. A. Modern technique of the assessment of danger of the magnetic field

In article the principles of a modern technique of the integrated control of an electromagnetic situation are considered. It is noted that when using modern techniques of measurement of intensity of a magnetic field, and also the existing normative documents it isn’t always possible to define admissible time of stay of the person in various zones of rooms with several sources of electromagnetic radiations that complicates development of ways of the organization of workplaces and actions for improvement and improvement of working conditions. Therefore there is a need of modernization of a technique of definition of admissible time of stay of people for a zone of influence of an electromagnetic field, including magnetic field, by expansion of controlled range of frequencies and definition of the most dangerous components of electromagnetic radiations.

Keywords: electromagnetic radiation, magnetic field, the control of parameters of electromagnetic fields, electromagnetic environment.

Bondareva L. A., Sukhanova M. V. Assessment the possibility of applying of methods of functional diagnostics plants for solving the problems of ecological monitoring

When conducting environmental monitoring comprehensive assessment of the environment can be it carried out by examining the state of the objects of plant origin. Plants are considered as an indicator of the state of the environment, reflecting the changes taking place in it. Level of functioning of the plant or of its separate systems, as well as the degree of its adaptation to the conditions of existence are evaluated using the methods of functional diagnostics. These methods are applicable to solve various problems, being developed for several decades however at the moment does not exist of their classification allowing both to analyze and assess the prospects for application of different groups of methods to solve problems of environmental monitoring. In the article carried out the selection of classification criteria based on which developed a classification of methods of functional diagnostics of plants, as well as presents an analysis of methods for each group.

Keywords: functional diagnostics, plants, ecologic monitoring, environment, classification, method.

Staroverov N. Е., Gryaznov A. Y., Zhamova K. K., Tkachenko K. G., Firsov G. A. The application of the method of microfocus x-ray for quality control of fruits and seeds reproductive diasporas

Application of a microfocal X-ray analysis for the analysis of fruits and seeds of some species of apple-trees allowed to reveal that in new conditions of growth not all types form fruits which have seeds. It is confirmed that use of a microfocal X-ray analysis allows to select quickly the seeds which are the most executed and not struck with wreckers and to use them for the subsequent crops and receiving bigger number of shoots. Were shown the prospects of the method in detecting problems with seeds collected during introduktcion works.

Keywords: microfocus X-ray, plant introduction, quality of seeds.
