Entropy,Seismicity Monitoring in the Armenian Highlands and Dynamics of the Akhurian Reservoir Filling     

S. Ts. Akopian 《Seismic Instruments》2018,54(1):113-120

The Armenian seismic system, which has a threshold magnitude of 6.2, has been identified based on the method of seismic entropy, makes it possible to monitor nucleation of strong earthquakes in the magnitude range of 6.2 ≤ M < 6.6, as well as to assess the seismic situation in Armenia and neighboring countries. A study of energy and track diagrams has revealed a fan-shaped tectonic pattern of stress concentrations with an apex in the Kurdistan knot. The analysis of entropy accumulation in seismic cycles carried out for the hierarchy of seismic systems of the Armenian Highlands helped in the identification of prognostic criteria. The results have been compared to the dynamics of Akhurian reservoir filling in 1983–2016.  相似文献

The transport-geographical location of Siberia's microregions: techniques and assessment results     

L.A. Bezrukov  Ts.B. Dashpilov 《Geography and Natural Resources》2010,31(4):299-307

It is established that the methodological tools for quantitative measurement of the transport-geographical location is insufficiently advanced. We suggest the algorithm for the technique of its cost assessment based on determining the “economic” distances and adapted to the peculiarities of the transport system of Siberia. We calculated the costs of the transport-geographical location of Siberian microregions (within administrative districts) with respect to the most important year-round sea ports for the current (the year 2005) and future (the year 2030) levels.  相似文献   

Population I pulsating stars     

Ts. G. Tsvetkov 《Astrophysics and Space Science》1985,117(2):227-243

Luminosities of Population I pulsating stars (Delta Scuti variables and classical cepheids) are investigated. From data for 80 Delta Scuti stars, semi-empirical period-luminosity-colour (P-L-C) relations and period-luminosity (P-L) relations are obtained for the four lowest modes of radial pulsations. The improvement of the accuracy of the stellar luminosity is determined when a P-L-C relation is used instead of the corresponding P-L relation. From data for 155 classical cepheids, empirical P-L relations are derived for short-period stars (logP1.1), long-period stars (logP>1.1), and s-cepheids. The comparison of the P-L relations for the two types of variable stars shows good agreement, but between them there is a gap with a dim nature.  相似文献   

The ecosystem of Lake Kenon: past and present (Transbaikal Territory,Russia)     

Alexey P. Kuklin  Gazhit Ts. Tsybekmitova  Evgenia P. Gorlacheva  Balzhit B. Bazarova  Alexey V. Afonin 《中国海洋湖沼学报》2016,34(3):507-516

Present-day conditions of the Lake Kenon ecosystem are determined by a combination of natural and anthropogenic factors.We have estimated the effects of a complex of factors on the condition of the abiotic environment and on specific biological components in the lake ecosystem.Change in biogenic load has caused an increase in the role of phytoplankton in the general balance of organic matter during the high-water period.Charophytes are the main dominants of bottom vegetation.Anthropogenic load has caused a decrease in both fish species and fish capacity.The lake application as a water reservoir-cooler has influenced the average annual water mineralization(from 420 mg/L to 530.0 mg/L with a maximum 654 mg/L in 1993) and fluctuations in its hydrochemical composition.The present composition of the lake is sulfate-hydrocarbonate-chloride calcium-sodic-magnesium in character.SO 4 – content is twice as much as the maximum permissible concentration in fishery waters.Water drainage from an ash disposal area to the lake has caused an increase in chemical-element concentrations including the heavy metals.Hg concentration in Perca fluviatilis muscles is 0.5 μg/g dry wt.Thus,understanding directions in the ecosystem of the water reservoir-cooler under changing hydrological conditions will let us forecast the consequences of new combined heat and power plant operation.  相似文献
