Fluctuating asymmetry of leaves of mountain ash (Sorbus aucuparia L.) as a bioindicator of aerotechnogenic pollution of the city of Orenburg
An assessment of environmental pollution in the city of Orenburg was conducted using the fluctuating asymmetry method. The common mountain ash was chosen as an environmental indicator. Leaf collection took place at seven points in the city with varying anthropogenic loads. The research aimed to determine the impact of aerotechnogenic ...
The modern economy of Russia’s Baltic regions in the municipal context

The companies’ revenues seem to reflect the economic situation in the municipalities better, however, it is determined not only by actual changes in the scale of production of goods and services but also by market fluctuations. Therefore, it is better to use a set of available indicators.
Results and discussion
For a basic assessment of the municipalities by the level of their economic development, we use Rosstat data on taxable personal income and income of sole ...
The use of the fluctuating asymmetry coefficient as a quality assessment criteria for morphometric adaptation of wood vegetation to technogenic conditions
The article is focused on the development of a methodology for quantitative assessment of adaptive changes magnitude in woody vegetation in the vicinity of the Gomel Polissyе major industrial enterprises on the basis the of leaf blades fluctuating asymmetry index. This justifies the possibility of using this value as a criterion for assessing the woody vegetation adaptation at the morphometric level and further production under technogenic environmental impact.

On interaction of a qubit with a fluctuating environment
It is shown that the equations of Gurvitz and Mozyrsky for a system consisting of a qubit interacting with a fluctuating environment in certain conditions are reduced to evolution equations of the qubit. Such evolution equations for the qubit can be generalized to the form, which implies the existence of entangled states of the combined system. Among these entangled ...

This article draws on the concept of the geographical demographic situation; it uses official statistics on Russian regions and Kaliningrad municipalities and settlements to explore the connection between rural settlement trends and employment fluctuations caused by structural shifts in Russian regional economies. It is shown how settlement polarisation affects differences in settlement trends of meso- and microdistrict levels. Regions are identified that have a capacity for rural-urban migration ...

in constant increase of water supply and subsequent rise of the sea level is defined as dominating. Two principle cycles in the sea level fluctuations were distinguished: a high-amplitude short-term cycle (2—3 years) and a low-amplitude long-term one (40—50 years). The concurrency of two events is traced: short-term cycles and major earthquakes in oceanic regions. It was shown that ...

Overall, the regional level of consumption is significantly below ...
