The distribution of forests by categories of protection is analyzed in accordance with the current normative documents on forest management in the territory of the Russian Federation. It is noted that protective forests are divided into 4 groups of protection categories; each of them includes specific types of protection categories. A considerable ...
The development of industry, the use of various chemicals in technological processes, the large emissions of industrial enterprises, the use of pesticides and chemical fertilizers in agriculture have caused environmental pollution with harmful substances. Environmental protection is now becoming one of the economic problems and is an extremely urge...
The plasma neutralization technology for the products of thermal waste processing—supertoxicants (polychlorinated dibenzodioxines, dibenzofurans, biphenyls, etc.)—is investigated. The problem of supertoxicants formation in the process of thermal processing for household and industrial waste of different composition is identified. To solve this prob...
An increasing demand for forest products incites a large number of log transportation operations, which may lead to negative consequences for the soil and the ecosystem as a whole. This paper is focused on establishing a mathematical model to estimate the soil deformation and compaction processes under tires of wheeled forest machines and individua...
The problem of rational use of resources is a priority for all mankind, which is confirmed by the presence of many national and interstate programs in the field of environmental management, resource conservation and improving the efficiency of environmental management. Forest complex play a special role in the rational use of natural resources. For...
The results of assessing the possibilities of using of biomass of fallen leaves as a filler of composite polymer materials with a polyvinyl chloride polymer matrix are presented. Samples of composites with biomass of fallen leaves we obtained by extrusion and hot pressing method. The dependences of their physical and mechanical properties on the co...
In the dynamic theory of martensitic transformations, temperature Ms of the start of transformation corresponds to conditions that are optimal for generating waves by nonequilibrium d electrons that control the growth of a martensitic crystal. The recognition of relative damping Г'e of s electrons plays a substantial role in this case. A general an...
Seasonal changes in chlorophyll (Chl) and carotenoid (Car) content were analyzed in needle samples from young Scots pines (Pinus sylvestris L.) growing in the thermal field zone at various distances from the petroleum gas flare. Experiments were performed in Khanty Mansi Autonomous Area (Yugra) of Russia throughout the autumn–winter–spring period. ...
Experimental compositions of composite bronzes reinforced with dendrites from maraging steel 00NiCo9Al1 (BrFeNiCoAl 23-8-3-1), the properties of which can be controlled over a wide range, have been developed. The dispersion of dendrites in these bronzes can only be controlled by the crystallization rate of the corresponding melt. Bronze BrFeNiCrSi ...
Adaptation of plant communities is an important factor for maintaining their functioning and stability in changing conditions. The aim of our research is study of the effect of soil moisture regime on the species richness and biomass of the herb layer for old-growth coniferous forests in the Ural Mountains (Russia). The research has been carried ou...
