The aim of our study was to complete the syntaxonomical scheme for grassland vegetation of the lowland, montane and alpine zones in the Pamir-Alai and western Tian Shan Mts in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. A total of 198 relevés were sampled in 2013–2018 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. They were classified with k-means algorithmwith tranforming cover values to three level scale of the following intervals0%,...

Use of advanced materials in protection against high-velocity impact and explosion

Aleksander V. Gerasimov, Leonid A. Igumnov & Anatoliy M. Bragov
Numerical studies of the behavior of combined barriers consisting of solid and porous materials were carried out during high-speed impact on them with thin plates. It is shown that the introduction of plates of porous materials into the composition of combined barriers can significantly reduce the amplitude of compression waves and reduce the likelihood of spall damage. Comparison of the results of numerical modeling of high-speed impact interaction processes with the experimental results of other...

Судьба текста в романе А. Битова «Преподаватель симметрии»

Екатерина Буханова
Статья посвящена выявлению в романе А. Битова «Преподаватель симметрии» концепции текста как экзистенциального феномена, функционирующего в процессе создания и при рецепции заложенных в нём смыслов. Альтернативные возможности текста концептуализировались Битовым как способ понимания бытия, закрепления авторских концепций в культуре, а также возможность их тиражирования, неизбежного искажения и профанирования. Определяются формы изменения авторского замысла при воплощении его в тексте и формы жизни текста в культурной традиции. Ключевые слова: А. Битов «Преподаватель симметрии», текст, рецепция, эволюция авторского...

The influence of stress triaxiality on ductility of α titanium alloy in a wide range of strain rates

V.V. Skripnyak, A.A. Kozulyn & V.A. Skripnyak
This work aimed to evaluate the combined effect of stress triaxiality and strain rate on the tensile behavior of the titanium alloy. The results of experimental studies and numerical modelling of the mechanical behavior of alpha titanium alloys were received and summarized. This paper presents the results of the research of mechanical behavior of titanium alloy VT 5-1 (this is an analog of Ti-5Al-2,25Sn) in a wide range of strain rates (from 0.001 to 1000...

Additional file 5 of Insights into adaptive evolution of plastomes in Stipa L. (Poaceae)

Additional file 5: Figure S2. The likelihood of adaptive pressure occurrence in particular CDS. The plots show the results of the Z-test, carried out for the 15-codon-long fragments. The values shown in the Y-axis (Z-scores) above 2.33 (blue horizontal line) correspond to the reliability level of 99%. Values above 3.09 (red horizontal line) correspond to the reliability of 99.9%.

Halophytic vegetation and adjoining plant communities in Middle Asia (Pamir-Alai and western Tian Shan)

Sebastian Świerszcz, Marcin Nobis, Anna Wróbel, Ewelina Klichowska, Sylwia Nowak & Arkadiusz Nowak
In this paper, we complete the syntaxonomical scheme for halophytic vegetation and adjoining plant communities of the lowland, montane and alpine zones in the Pamir-Alai and western Tian Shan in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. A total of 217 relevés were sampled in 2014–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. Modified TWlNSPAN was used to classify plant communities based on species composition. The cover-abundance scale was transformed...
