CURRENT STATE OF THE NATURE MONUMENT “TROUT CREEK SULA” (NORTHERN DISTRICT OF ORENBURG REGION) [№ 8 ' 2017]
Information on the state of natural complexes of specially protected natural areas is of great importance in maintaining the effective structure of the regional environmental framework. In the field season of 2017, a comprehensive survey and assessment of the current status of the natural monument “Trout Creek Sula”, located in the Northern District of the Orenburg region, was carried out. Two species of plants listed in the Red Book of the Russian Federation and nine species of plants listed in the Red Book of the Orenburg Region were identified on its territory. It is not possible to confirm or deny the presence of such rare species of fish as the trout trout Salmo trutta morpha fario (Linnaeus, 1758) and the European grayling Thymallus thymallus (Linnaeus, 1758) in the waterfalls of the Nature Reserve “Trout Creek Sula” in waterways. The habitat in the surveyed streams of the common minnow was Phoxinus phoxinus (Linnaeus, 1758) and the silver crucian Carassius auratus gibelio (Bloch, 1782). Among the amphibians along the banks of the streams there is a lake frog Pelophylax ridibundus (Pallas, 1771), reptiles are viviparous Zootoca vivipara (Lichtenstein, 1823) and Lacerta agilis (Linnaeus, 1758) lizards, usually Natrix natrix (Linnaeus, 1758). It was noted that to the natural monument “Trout Creek Sula” to the north of the channel of the Sula Creek there are unbroken slopes characterized by a high degree of preservation of steppe phytocenoses occupying them and saturation of rare and needy species of plants. Taking into account that the forest steppe as a whole and the meadow steppes in particular are significantly disturbed, and the phytocoenoses on the territories adjacent to the nature monument “Trout Brook Sula” have significant conservation value, we recommend to consider the possibility of expanding the boundaries of the nature monument, including in its composition the slopes with the preserved steppe vegetation.

ALGORITHM SEARCH OF OPTIMAL CONSTRUCTION VARIANT BY METHOD OF LOCAL LAGRANGE MULTIPLIERS VARIATIONS [№ 9 ' 2013]
The paper deals with the aspects of efficient algorithm construction for optimal projecting of structures. The investigation with the appliance of generalized Lagrange methods resulted in the construction of algorithm which does not require the convexity of functions, and more over, the uninterrupted multitude of permissible points. The method under investigation has a number of advantages regarding calculating, that is the replacement of a conventional problem by an un conventional one and the possibility of its complex use in combination with some other methods of an absolute optimization.
