The image of a girl in the painting by V.I. Surikov “The Morning of the Streltsy Execution”: the experience of interpretation
Authors: Шишин М.Ю. 
Published: March 2023

Статья посвящена анализу первой исторической картины В.И. Сурикова «Утро стрелецкой казни» в контексте творчества художника, чьи произведения являются осевыми для российской культуры. Учитывая опыт предыдущих подходов к анализу и интерпретации этой картины, предлагается дополнить взгляд на ее толкование и увидеть более крупные идейные пласты, характеризующие В.И. Сурикова как самобытного философа, остро воспринимающего проблемы свой Родины и вскрывающего глубинные корни их возникновения. Находясь в России во времена серьезных потрясений, художник обращается к одному из переломных периодов отечественной истории и не только изображает противостояние Петра Первого и его сводной сестры царевны Софьи, стрельцов и преображенцев, но и стремится показать, как именно эти события понимаются и оцениваются всем народом. В фокусе внимания в данном исследовании находится образ девочки на переднем плане. Анализ одного персонажа в произведении и раскрытие его семантики продолжает традицию определения значимых деталей в картинах В.И. Сурикова и представляет его как художника философского склада.
The article is devoted to the analysis of the first historical painting by Vasily Surikov “The Morning of the Streltsy Execution” in the context of the artist's oeuvre, whose works are axial for Russian culture. Taking into account the experience of previous approaches to the analysis and interpretation of this picture, it is proposed to supplement the view on its explication and see larger ideological layers that characterize V.I. Surikov as an original philosopher, acutely perceiving the problems of his homeland and revealing the deep roots of their occurrence. Being in Russia at the time of serious upheavals, the artist turns to one of the crucial points in Russian history. It not only depicts the confrontation between Peter the Great and his half-sister Princess Sophia, streltsy and the Preobrazhensk regiment, but also seeks to show exactly how the people understood and evaluated these events. In this study, the focus is on the image of the girl in the foreground. The analysis of one character in the picture and the disclosure of its semantics continues the tradition of determining significant details in the paintings of V.I. Surikov and presents him as a philosophical artist.

Objective. To study primary resistance of H. pylori to clarithromycin in residents of Gomel region by real-time polymerase chain reaction (PCR RT) using TaqMan® MGB probes.Materials and methods. The study included 184 patients diagnosed with gastritis and duodenitis, K29, median age 48.5 years (25% and 75% were 37 and 61 years old). According to the patients’ questionnaires, no clarithromycin-based eradication therapy was administered. To determine the resistance of H. pylori to clarithromycin, a PCR RV method using TagMan® MGB probes was used.Results. All 184 tested DNA samples were positive for the Rnase P gene (ICS) and were considered in further analysis (Ct, HEX 20.20-34.14). DNA from the cagH gene (Ct, FAM 21.26-33.04), indicating infection with the bacterium, was confirmed in 152 samples (82.6%). DNA from the 23SrRNA gene (point mutations A2142G and A2143G) was detected in 16 of 152 DNA samples 10.5 % (Ct, Hex 20.24-31.17). The positive control samples had characteristic curve growth in the corresponding detection channels; no curve growth was observed in the negative samples.Conclusion. The primary resistance of H. pylori to clarithromycin in the residents of Gomel region was 10.5%, and the use of triple first-line eradication therapy, including PPIs, amoxicillin and clarithromycin, as empirical in this region is consistent with the Maastricht III-VI recommendations and Decree of the Ministry of Health of the Republic of Belarus of 01.06.2017 № 54: clinical protocol “Diagnosis and treatment of patients with digestive diseases.” The use of PCR RT using TaqMan® MGB probes is justified to determine the resistance of H. pylori to clarithromycin, to prescribe individualized treatment and to evaluate the effectiveness of eradication regimens.

The current research includes the synthesis and crystallographic characterization of 2-phenylaminotetrahydro-1,3-thiazepine hydrochloride (HPAT) and 2-phenyliminohexa- hydro-1,3-thiazepine (PIT) compounds. 2-Phenylaminotetrahydro-1,3-thiazepine hydro-chloride was synthesized by cyclization of 1-(4-hydroxybutyl)-3-phenylthiourea in an acidic condition. The second compound, 2-phenyliminohexahydro-1,3-thiazepine, was obtained by neutralizing 2-phenylaminotetrahydro-1,3-thiazepine hydrochloride with sodium hydrocarbonate. Both compounds were characterized by the single-crystal X-ray diffraction method. Crystal data for C11H17N2OClS (HPAT): orthorhombic, space group P212121 (no. 19), a = 4.97183(14) Å, b = 15.1169(4) Å, c = 17.7376(5) Å, V = 1333.14(6) Å3, Z = 4, μ(CuKα) = 3.859 mm-1, Dcalc = 1.299 g/cm3, 9243 reflections measured (7.684° ≤ 2Θ ≤ 152.042°), 2749 unique (Rint = 0.0314, Rsigma = 0.0255) which were used in all calculations. The final R1 was 0.0351 (I > 2σ(I)) and wR2 was 0.0911 (all data). Crystal data for C11H14N2S (PIT): monoclinic, space group P21/n (no. 14), a = 9.6303(9) Å, b = 9.8938(6) Å, c = 11.5627(9) Å, β = 103.419(8)°, V = 1071.62(14) Å3, Z = 4, μ(CuKα) = 2.357 mm-1, Dcalc = 1.279 g/cm3, 3938 reflections measured (10.798° ≤ 2Θ ≤ 152.328°), 2172 unique (Rint = 0.0288, Rsigma = 0.0330) that were used in all calculations. The final R1 was 0.0431 (I > 2σ(I)) and wR2 was 0.1219 (all data). The asymmetric unit of HPAT contains one protonated amine, one chlorine anion, and one water molecule. Chlorine anion and water molecules play the role of the bridge in chain formation along the a- and b-axis through H-bonds with N-H hydrogen atoms. Furthermore, the Hirshfeld surface analyses are performed to determine the nature of the intermolecular contacts stabilizing the crystal structures of 2-phenylaminotetrahydro-1,3-thiazepine hydrochloride and 2-phenyliminohexahydro-1,3-thiazepine.
Did the Bronze Age deforestation of Europe affect its climate? A regional climate-model study using pollen-based land-cover reconstructions

Published: March 2023

Abstract. This paper studies the impact of land use and land-cover change (LULCC) on the climate around 2 500 years ago (2.5 ka), a period of rapid transitions across the European landscape. One global climate model was used to force two regional climate models (RCMs). The RCMs used two land cover descriptions. The first was from a dynamical vegetation model representing potential land cover; the second a land cover description reconstructed from pollen data by statistical interpolation. The two different land covers enable us to study the impact of land cover on climate conditions. Since the difference in landscape openness between potential and reconstructed land cover is mostly due to LULCC, this can be taken as a measure of early anthropogenic effects on climate. The use of two RCMs enables us to study how sensitive climate models can be to land-cover changes. The results show that the simulated 2.5 ka climate was warmer than the simulated pre-industrial (PI) climate. The largest differences are seen in northern Europe, where the 2.5 ka climate is 2–4 °C warmer than PI. In summer, the difference between the simulated 2.5 ka and PI climates is smaller (0–3 °C), with the smallest differences in southern Europe. Differences in seasonal precipitation are mostly within ±10 %. In parts of northern Europe, the 2.5 ka climate is up to 30 % wetter in winter than that of PI. In summer there is a tendency for the 2.5 ka climate to be drier than PI in the Mediterranean region. The results also suggest that LULCC at 2.5 ka significantly impacted the climate in parts of Europe. Simulations including reconstructed LULCC (i.e. those using pollen-derived land cover descriptions) give up to 1 °C higher temperature in parts of northern Europe in winter and up to 1.5 °C warmer in southern Europe in summer than simulations with potential land cover. This relatively strong response implies that anthropogenic land cover changes that had occurred by the late prehistoric period may have already affected the European climate by 2.5 ka.
Dislocation and disclination densities in experimentally deformed polycrystalline olivine

Published: March 2023

Abstract. We report a comprehensive data set characterizing and
quantifying the geometrically necessary dislocation (GND) density in the
crystallographic frame (ραc) and disclination density
(ρθ) in fine-grained polycrystalline olivine deformed in
uniaxial compression or torsion, at 1000 and 1200 ∘C, under a confining pressure of 300 MPa. Finite strains range from 0.11 up
to 8.6 %, and stresses reach up to 1073 MPa. The data set is a selection
of 19 electron backscatter diffraction maps acquired with conventional
angular resolution (0.5∘) but at high spatial resolution (step
size ranging between 0.05 and 0.1 µm). Thanks to analytical
improvement for data acquisition and treatment, notably with the use of ATEX (Analysis Tools for Electron and X-ray diffraction)
software, we report the spatial distribution of both GND and disclination
densities. Areas with the highest GND densities define sub-grain boundaries.
The type of GND densities involved also indicates that most olivine sub-grain
boundaries have a mixed character. Moreover, the strategy for visualization also
permits identifying minor GND that is not well organized as sub-grain boundaries
yet. A low-temperature and high-stress sample displays a higher but less organized GND density than in a sample deformed at high temperature for a similar
finite strain, grain size, and identical strain rate, confirming the action
of dislocation creep in these samples, even for micrometric grains (2 µm). Furthermore, disclination dipoles along grain boundaries are identified
in every undeformed and deformed electron backscatter diffraction (EBSD) map, mostly at the junction of a
grain boundary with a sub-grain but also along sub-grain boundaries and at
sub-grain boundary tips. Nevertheless, for the range of experimental
parameters investigated, there is no notable correlation of the disclination
density with stress, strain, or temperature. However, a broad positive
correlation between average disclination density and average GND density per
grain is found, confirming their similar role as defects producing
intragranular misorientation. Furthermore, a broad negative correlation
between the disclination density and the grain size or perimeter is found,
providing a first rule of thumb on the distribution of disclinations. Field
dislocation and disclination mechanics (FDDM) of the elastic fields due to
experimentally measured dislocations and disclinations (e.g., strains/rotations and stresses) provides further evidence of the interplay
between both types of defects. At last, our results also support that
disclinations act as a plastic deformation mechanism, by allowing rotation
of a very small crystal volume.
