Forest resource is the most important natural resource. The Leningrad Region is one of the most developed subjects of the Russian Federation according to economic indicators. Logging, wood processing and timber exports are carried out in the region due to the reserves of forest resources. The consumption of forest resources should not exceed the productive natural forces. Improving forest management, ensuring rational use of forests, maintaining the ecological potential of the forest fund are essential aims. The s...

Educational resources collections in the Botanical garden of the Autonomous educational institution of higher professional education "Leningrad state University named after A. S. Pushkin", with more than 400 species and varieties of tropical and subtropical plant have been reviewed. Plants related to different biomes, ecological groups, floristic kingdoms and regions and plants cultivated in agriculture have been specified. The directions of using a collection of plants in the course of training courses of the dis...

The purpose of the present study is to apply the new methods of multi-parametric analysis to moonquakes. It should be noted such physical phenomena as moonquakes are some kinds of complex systems. As the works in which analysis of moonquakes observations is conducted have shown, lunar seismophysics is much more complex process than Earth's geophysics. This is why to study the physical nature of moonquakes and their parameters it is necessary to use methods of statistical physics and robust estimates. Currently, th...

The present work is focusing on construction and analysis of 5 lunar models using space and ground observations. Firstly, it should be noted that the task of building a model of the lunar macro-figure relative to its center of mass and axes of inertia does not have a definitive solution yet. Within the present work the models of the lunar macro-figure are developed on the basis of space and ground observations. The methods of observation had implied binding of lunar objects to stars, i.e. celestial coordinate syst...

Urbanization is a global process most widely spread in the second half of the 20th century. In 2009, the urban population was equal to the size of the rural population and its importance is growing now. City conditions are so specific that at present some scientists note the excistance of processes that form a new adaptive type of man at the phenotypic level ? urban type in addition to already existing high-mountainous, arctic, temperate latitudes and tropical types. The main groups of factors that affect the stat...
