    The modern level of scientific researches allows to develop the ideas about coherence of natural processes. The technique of the express analysis of the territory's ecological condition, realized in the form of software product is presented. The technique represents set of the algorithms, allowing to make the automated processing the information. The estimation of an ecological condition is carried out in field conditions in a mode of real time by direct measurements of number and an abundance of the dominating plants species, input of the information in a database, calculation of parameters of a biodiversity, types of modes of 10 direct-action factors, comfort of environment conditions and sufficiency of environment conditions for each plant species. The technique is intended for a wide range of users: experts in the field of preservation of the environment, ecological monitoring, ecological safety; the engineering and special services which are carrying out the ecological control of harmful manufactures; for an estimation of an ecological condition of city territories, dumps, waste grounds, etc.; is a methodical management for training of students and the personnel.Π‘ΠΎΠ²Ρ€Π΅ΠΌΠ΅Π½Π½Ρ‹ΠΉ ΡƒΡ€ΠΎΠ²Π΅Π½ΡŒ Π½Π°ΡƒΡ‡Π½Ρ‹Ρ… исслСдований позволяСт Ρ€Π°Π·Π²ΠΈΠ²Π°Ρ‚ΡŒ ΠΈΠ΄Π΅ΠΈ ΠΎ взаимосвязанности ΠΏΡ€ΠΈΡ€ΠΎΠ΄Π½Ρ‹Ρ… процСссов.

    The concept of biomonitoring is based on the on a basic postulate of ecology, that the condition of bioobject and its adaptable parameters reflects a condition of the environments. Each type of biomonitoring has a universal purpose, main of which is the estimation of a biota's condition, and on this information base - an estimation of quality of environment; depending on bioobject various types of biomonitoring are allocated. The typical schemes of biomonitoring allowing to control a radioecological condition of geotechnical systems are developed and tested. The technique and results are of interest for a wide range of experts in the field of preservation of the environment, ecological monitoring, ecological safety, the engineering and special services which are carrying out the ecological control of harmful manufactures, can serve as a methodical management for training of students and the personnel.ΠšΠΎΠ½Ρ†Π΅ΠΏΡ†ΠΈΡ Π±ΠΈΠΎΠΌΠΎΠ½ΠΈΡ‚ΠΎΡ€ΠΈΠ½Π³Π° построСна Π½Π° ΠΎΡΠ½ΠΎΠ²ΠΎΠΏΠΎΠ»Π°Π³Π°ΡŽΡ‰Π΅ΠΌ постулатС экологии, Ρ‡Ρ‚ΠΎ состояниС Π±ΠΈΠΎΠΎΠ±ΡŠΠ΅ΠΊΡ‚Π° ΠΈ Π΅Π³ΠΎ Π°Π΄Π°ΠΏΡ‚Π°Ρ†ΠΈΠΎΠ½Π½Ρ‹Π΅ ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€Ρ‹ ΠΎΡ‚Ρ€Π°ΠΆΠ°ΡŽΡ‚ состояниС ΠΎΠΊΡ€ΡƒΠΆΠ°ΡŽΡ‰Π΅ΠΉ срСды.

    Orientational mobility and relaxation spectra of dendrimers : theory and computer simulation

    Get PDF
    The developed theory of the orientational mobility of individual segments of a perfectly branched dendrimer is used to calculate the relaxation spectrum of a dendrimer. Frequency dependences of NMR relaxation 1/T1 and of the nuclear Overhauser effect have been theoretically calculated from the Brownian dynamics simulation data. The dendrimer segmental orientational mobility is governed by three main relaxation processes: (i) the rotation of the dendrimer as a whole, (ii) the rotation of the dendrimer's branch originated from a given segment, and (iii) the local reorientation of the segment. The internal orientational mobility of an individual dendrimer segment depends only on the topological distance between this segment and the terminal shell of the dendrimer. Characteristic relaxation times of all processes and their contributions to the segmental mobility have been calculated. The influence of the number of generations and the number of the generation shell on the relaxation times has been studied. The correlation between the characteristic times and the calculated relaxation spectrum of the dendrimer has been established

    Local orientational mobility in dendrimers. Theory and computer-aided simulation

    No full text
    The orientational mobility of segments in dendrimers are studied by the method of Brownian dynamics, and the results are analyzed in terms of an earlier proposed analytical theory. The orientational autocorrelation function for the cosine of an angle of segmental rotation in dendrimers of a given generation P 1(t) is controlled by three relaxation processes with the corresponding relaxation times. Characteristic times and the contribution from the above processes to P 1(t) are calculated. The first process refers to the local mobility of a selected segment; the second process, to the rotations of a dendrimer branch, which originates from the selected segment of a given generation; and the third process, to the rotation of a dendrimer macro-molecule as a whole. The proposed approach makes it possible to estimate the relaxation spectrum of a dendrimer by studying the orientational mobility of segments in different generations. The relaxation times can be used to describe various relaxation processes observed by different experimental methods, such as dielectric relaxation, NMR, dynamic birefringence, and polarized luminescence
