The crossing range of a shock adiabate and a melting curve has been considered. The melting curve has been presented by Simon equation. The effect of a first kind phase transition on the form of the shock adiabate has been studied as in the case when the shock adiabate of the solid crosses its melting curve. The crossing of the adiabate of solid and the melting curve determines the beginning of melting state. The crossing of the adiabate of a liquid and melting curve determines the state of the melting termination. The crossing of the shock adiabate and the critical isotherme of a date substance is the example of the effect related to the second kind phase transition on the form of the shock adiabate. The generated model illustrates the behavior of low-melting metals: Pb, Bi, Cd and Sn II. The experimental data of the shocked substances has been analyzed. It is noted that the singularities in change of properties vs temperature possess place upon the critical temperature. The model results have been confirmed by the well-known experimental data. The crossing of the shock adiabate of solid and the melting curve produces a discontinuity of the shock adiabate. A derivative of shock velocity on particle velocity in a liquid range decreases. The crossing of the shock adiabate and the critical isotherme produces a break of a relationship of the shock-particle velocities. The singularities in a change of the properties vs the temperature take place whenever the crossing of the shock adiabate and the critical isotherme is present. There following singularities occur: a break curve, a curve bend, a minimum and a maximum. © PNRPU.

N-Benzylidene-4-(1-cyclohepta-2,4,6-trienyl)aniline (IIIa), N-(4-bromophenylmethylene)-41-(1-cyclohepta-2,4,6-trienyl)aniline (IIIb), and N-(4-methoxyphenylmethylene)-41-(1-cyclohepta-2,4,6- trienyl)aniline (IIIc) were prepared by tropylation of the corresponding imines. 4-(5-Dibenzo[a,d]cyclohepten-5-yl)aniline (V) was prepared by the reaction of aniline with dibenzosuberenole (VI); N-benzylidene-4-(5-dibenzo[a,d]cyclohepten- 5-yl)aniline (IV), from benzalaniline and V. A study of the antimycobacterial activity of the synthesized compounds showed that IIIa, IIIc, and IV exhibited inhibiting activity against Staphylococcus aureus at concentrations >1000 μg/mL. Compounds IIIa and V at concentrations of 1000 μg/mL inhibited growth of E. coli and Candida albicans, respectively. © 2013 Springer Science+Business Media New York.

The main parameters of the test polygon selection are considered. On the basis of engineering-geological criteria the border dividing is allocated the explored territory for possible development of negative geological processes. This feature of the engineering geological structures is a key to justify the application of the various geophysical methods available for stability control of territories with high rates of land subsidence.

The results of the study of flowering of 6 species and 2 interspecific hybrids of subgenus Syringa are described in this article, which include the following: Sections Villosae C. K. Schneid.: S. josikaea J. Jacq. ex Rchb., S. emodi Wall. ex Royle, S. wolfii C. K. Schneid., S. sweginzowii Koehne & Lingelsh., S. villosa Vahl, S. × prestoniae McKelvey (S. komarowii subsp. reflexa × S. villosa), and S. × henryi C. K. Schneid. (S. josikaea × S. villosa); and section Syringa: S. vulgaris L., obtained from the collection of siringarium at the Professor A. G. Genkel Botanical Gardens of the Perm State National Research University. Each of the studied Syringa species and cultivars differs with some aspects of the inflorescence structure: The number of flowers and their arrangement in the partial inflorescence and the number of partial inflorescences and their arrangement on the main axis. The beginning and the duration of the partial inflorescences' flowering depend on their arrangement on the main axis and the number of flowers in the partial inflorescence. The clustering of partial inflorescences into three categories, basal, lateral, and apical, was implemented. The inflorescence flowers are characterized by acropetal type of blooming. The duration of bush flowering of the studied species and cultivars varies from 8 to 19 days, and the duration of inflorescence flowering-from 6 to 13 days. The peculiarities of diurnal variation of flowering are discovered: The majority of species and interspecific hybrids of Syringa are characterized by morning anthesis, which continues till 12 noon. Anthesis of S. × henryi species essentially begins at about 8 a.m., and also between 2 p.m. and 4 p.m. S. wolfii flowers have the diurnal type of anthesis, and the majority of flowers begin to open at noon till 2 p.m. Despite entomophility of the lilac flowers, only occasional attendance of plants by insects is recorded, among which are pollinators (Apis mellifera L., Bombus hortorum L.) and a visitor (Cetonia aurata L.).

A method for assessing the state TKT to underworked territory is developed. The estimation of rocks TKT on physical and mechanical properties is made, highlighted the anomalous areas. Spatial models of capacities rock TKT, capacities detrital soil, the average value (Rc) of strength in a water-saturated state are constructed.

The soil genesis and classification position in different altitude-vegetation belts of the Middle Urals were determined on the territory of the Basegi Nature Reserve during 2009–2013. For improving the soil diagnostics (using the Northern Baseg mountain as an example), we quantified the group composition of iron compounds, and examined the distribution types of iron compounds across the soil profiles. The character of profile distribution of iron forms is governed by physical weathering and soil-forming processes: burozem formation, biological iron fixation, gleying, oxidogenesis, alfehumic illuviation, and redox alfehumic differentiation. No signs of podzolization were revealed in the soils. For the goletz belt, dry peat podburs (ocherous subtype) and ferruginized litho-sod-eluvozem were identified for the first time in conditions of the mountain tundra on the western macroslope of the Middle Urals. The study determined different combinations of the processes in the soils for the altitude-vegetation belts. © 2016, Pleiades Publishing, Ltd.

Conditions of vanadium(V) extraction from sulfuric and hydrochloric acid solutions with kerosene solutions of hydrazides and N',N'-dimethylhydrazides derived from fractions of Versatic 10 and Versatic 1519 branched higher carboxylic acids were studied. Conditions of vanadium(V) back extraction from organic phase were studied. For diluted acid solutions, ratios were found to be [V(V)]: [reagent] = 1: 1 and 1: 5 for sulfuric acid media and 1: 1 and 1: 8 for hydrochloric acid media. © 2016 Pleiades Publishing, Ltd.

As a result of this study, the author developed and set forth a number of theories, as well as methodological and practical recommendations for socioeconomic priorities that could help to improve the stability of the food supply in the region. The author redefines the idea and the contents of the socioeconomic priorities that could help to improve the stability of the food supply, which, in opinion of the author, constitute the main direction of potential improvement of the economic relations in the manufacturing, marketing and consumption fields. The author reveals and systematizes the key elements of the cluster analysis and determines cluster groups, with the aim to optimize interaction of intraregional industries in terms of manufacturing, transporting, processing and marketing of the goods produced. © IDOSI Publications, 2013.

The classic problem of the motion of a point mass (projectile) thrown at an angle to the horizon is reviewed. The air drag force is taken into account with the drag factor assumed to be constant. An analytical approach is used for the investigation. Application field of the previously obtained approximate analytical formulas has been expanded both in the upward launch angle, and in the direction of increase of the initial speed of the projectile. The motion of a baseball is presented as an example. It is shown that in a sufficiently wide ranges of initial velocity and launch angle the relative error in calculating the distance of the ball does not exceed 1%. © The Sociedade Brasileira de Física.
