Additional Insulin Is Required in Both the Early and Late Postprandial Periods for Meals High in Protein and Fat: A Randomized Trial.

The pattern and quantity of insulin required for high-protein high-fat (HPHF) meals is not well understood. This study aimed to determine the amount and delivery pattern of insulin required to maintain euglycemia for 5 hours after consuming a HPHF meal compared with a low-protein low-fat (LPLF) meal. This randomized crossover clinical trial, conducted at 2 Australian pediatric diabetes centers, included 10 patients (12-21 years of age) with type 1 diabetes for ≥ 1 year. Participants were randomized to HPHF meal (60 g protein, 40 g fat) or LPLF meal (5 g protein, 5 g fat) with identical carbohydrate content (30 g). A modified insulin clamp technique was used to determine insulin requirements to maintain postprandial euglycemia for 5 hours. Total mean insulin requirements over 5 hours were measured. The total mean insulin requirements for the HPHF meal were significantly greater than for the LPLF meal (11.0 [CI 9.2, 12.8] units vs 5.7 [CI 3.8, 7.5] units; P = 0.001). Extra intravenous insulin was required for HPHF: 0 to 2 hours (extra 1.2 [CI 0.6, 1.6] units/h), 2 to 4 hours (extra 1.1 [CI 0.6, 1.6] units/h), and 4 to 5 hours (extra 0.6 [CI 0.1, 1.1] units/h) after the meal. There were marked inter-individual differences in the quantity of additional insulin (0.3 to 5 times more for HPHF) and the pattern of insulin delivery (0%-85% of additional insulin required in the first 2 hours). The addition of protein and fat to a standardized carbohydrate meal almost doubled the mean insulin requirement, with most participants requiring half of the additional insulin in the first 2 hours.

Research of the concept of “wedding” in modern linguistics and related traditions in the Russian and foreign worldviews

This article examines the concept of “wedding” and related traditions in the Russian and foreign worldviews. Using the Russian-language and English-language explanatory dictionaries, the author analyzes the meaning of the concept of “wedding”, gives a brief description of some aspects of the wedding ceremony of the past on the example of Russia, Hungary and Great Britain; as well as provides the results of the original survey created in the Russian and English languages and conducted in electronic form on the platforms Survio and GoogleForms, which determined the attitude towards wedding traditions and customs in Russia and abroad. The survey involved unmarried 120 people, aged from 17 to 26; among them, 60 people are the residents of Russia (Russians) and 60 people are the residents of foreign countries of different nationalities – Bulgarians, Hungarians, Italians, Mexicans, Venezuelans, Vietnamese, Malaysians, Nigerians, and citizens of the United Arab Emirates. Based on the conducted survey and dictionary sampling, the author concludes that despite the identical semantic content of the concept in different languages, the national concept spheres are vary depending on the customs characteristic to each nation. If in the past, the wedding was a grand event with lots of guests and the observance of all the necessary national customs and traditions, then modern society suggests that wedding should be a memorable event, however rather unpretentious. All respondents have certain knowledge about wedding traditions and customs of their nation that should be observed and kept dearly; however most of them see their wedding day among just closest relatives and friends.

Microcommitments: The Effect of Small Commitments on Student Success

We conducted a randomized control trial with nearly 1,000 students to test whether using a text-message-based tool that provides small commitments with social accountability helps students procrastinate less and maintain engagement with course material, yielding improved academic performance. All students received identical content via text message, but the treatment group engaged with an online platform encouraging commitments and featuring a social feed with rankings. The analysis reveals that microcommitments with social accountability improved academic performance relative to students who received simple nudges. The increase is equivalent to 3 percentage points on an exam, driven by online and hybrid classes.

Experimental analysis of two-period quasi-periodic oscillations in a turbulent hydrogen combustor

The thermo-acoustic instability behavior of non-premixed hydrogen combustion is analyzed in the present work with the inlet Reynolds number, Re as the control parameter. It is observed that the dominant frequency (mode) shifts from the fundamental duct-acoustic mode to the first harmonic, as Re is varied. Continuous wavelet transform of the pressure oscillations reveals that at different Re, the dynamical nature of oscillations is topologically different, although they have identical spectral content. An interesting dynamical behavior identified as two-period quasi-periodic oscillations is observed, which has not been reported in prior literature. The state is seen to be unstable to incremental changes in Re and transitioning to limit cycle oscillations subsequently. Further diagnosis employing time-resolved OH* chemiluminescence and particle image velocimetry reveals the amplitude modulation of the quasi-periodic oscillation as a result of staggered vorticity distribution across the bluff body which results in asymmetric heat release rate distribution. A general framework for such oscillations is then applied, leading to identifying specific conditions that need to be satisfied to enable the existence of these oscillations. This study leads to novel observations on the asymmetric nature of shear layers, which can result in hitherto observed dynamical states.

Microstructure, Hardness, Tensile Strength, and Sliding Wear of Hypoeutectic Al–Si Cast Alloys with Small Cr Additions and Fe‐Impurity Content

Herein, the influence of Cr additions on the solidification parameters, as‐cast microstructures, and mechanical properties of Al–Si alloys with Fe‐impurity is investigated. Al–Si–Cr alloys with 3% and 7% Si and 0.25% and 0.40% Cr are developed. Solidification experiments are performed using an instrumented cooling casting apparatus permitting the obtainment of vertical upward‐solidified ingots. The morphological and phase structures are characterized by optical and scanning electron microscopy and X‐ray diffractometry. Hardness, tensile, and dry sliding wear tests are conducted to determine the mechanical properties. The Cr addition to the Al–Si alloys leads to the formation of α‐Al(Si, Fe)Cr interdendritic precipitates, suppressing the formation of undesired needle‐like β‐intermetallic compounds (Al5FeSi). It is noted that both higher alloy Cr content and cooling rate induce refinement in the dendrite arm spacing, and improvement in both hardness and ultimate tensile strength when considering the alloys with identical Si content. The coefficient of friction slightly increases with increasing alloy Cr content and with coarsening of the microstructure. Correlations between the wear rate and secondary dendrite arm spacing are proposed, in which the wear rate decreases with decrease in the secondary dendrite arm spacing and increase in the alloy Cr content and hardness.

Sequencing of Organellar Genomes of Nowellia curvifolia (Cephaloziaceae Jungermanniales) Revealed the Smallest Plastome with Complete Gene Set and High Intraspecific Variation Suggesting Cryptic Speciation

The leafy liverwort Nowellia curvifolia is a widespread Holarctic species belonging to the family Cephaloziaceae. It is made up of a newly sequenced, assembled and annotated organellar genomes of two European specimens, which revealed the structure typical for liverworts, but also provided new insights into its microevolution. The plastome of N. curvifolia is the second smallest among photosynthetic liverworts, with the shortest known inverted repeats. Moreover, it is the smallest liverwort genome with a complete gene set, since two smaller genomes of Aneura mirabilis and Cololejeunea lanciloba are missing six and four protein-coding genes respectively. The reduction of plastome size in leafy liverworts seems to be mainly impacted by deletion within specific region between psbA and psbD genes. The comparative intraspecific analysis revealed single SNPs difference among European individuals and a low number of 35 mutations differentiating European and North American specimens. However, the genetic resources of Asian specimen enabled to identify 1335 SNPs in plastic protein-coding genes suggesting an advanced cryptic speciation within N. curvifolia or the presence of undescribed morphospecies in Asia. Newly sequenced mitogenomes from European specimens revealed identical gene content and structure to previously published and low intercontinental differentiation limited to one substitution and three indels. The RNA-seq based RNA editing analysis revealed 17 and 127 edited sites in plastome and mitogenome respectively including one non-canonical editing event in plastid chiL gene. The U to C editing is common in non-seed plants, but in liverwort plastome is reported for the first time.

Variation of amino acids in Prunus persica cultivars leaves with regard to leaf age

The central role of amino acids in cellular and plant physiology is of current interest. Information related to the implication of amino acids during leaf age is still scarce. This study examined changes in the profile of amino acids extracted from leaves of five peach cultivars (‘Early Maycrest’, ‘Sweet Cap’, ‘O’Henry’, ‘Flordastar’, and ‘Rubirich’) grown in the region of Sidi Bouzid, central-western Tunisia with respect to leaf age.Seventeen amino acids, aspartic acid (Asp), serine (Ser), glycine (Gly), proline (Pro), tyrosine (Tyr), valine (Val), methionine (Met), cysteine (Cys), tryptophan (Trp), leucine (Leu), phenylalanine (Phe), isoleucine (Ile), lysine (Lys), glutamic acid (Glu), arginine (Arg), alanine (Ala), and histidine (His) were quantified. Significant variations were observed for Asp, Glu, Ser, Gly, Ala + Arg, Pro, Val, Ile + Trp, and Lys in relation to the leaf age. On average, young leaves (106.48–142.18 mg g−1 DW) contained higher amounts of most amino acids than mature leaves (97.33–110.27 mg g−1 DW). Approximately identical contents of amino acids were found in the different cultivars.In conclusion, P. persica leaves are a very rich source of amino acids (about 10% DW), and therefore deserves further investigation for their potential application in the nutraceutical, food, feed, and pharmaceutical industries.

Characterization of the complete mitochondrial genome of Notocotylus sp. (Trematoda, Notocotylidae) and its phylogenetic implications

The parasite genus Notocotylus comprises at least 50 species colonizing mainly aquatic birds and to a lesser extent some mammals, particularly rodents. Here trematode specimens isolated from a wild black swan were characterized and identified to belong to the genus Notocotylus via morphological and molecular analyses. Phylogenetic position of the isolate among other trematodes was determined based on the ribosomal internal transcribed spacer (ITS) 1 and 2. The complete mitochondrial (mt) genome of the isolate was amplified, sequenced, assembled, analyzed, and annotated. The isolate has an AT-rich mt genome (14,317 bp in length) that comprises 12 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes. The Notocotylus isolate identified in this study has relatively high mt genome sequence identity and identical gene content and arrangement to a known Notocotylidae species, Ogmocotyle sikae. The isolate formed a genetic clade with O. sikae in phylogenetic analysis of the concatenated PCG amino acid sequences. Compared to the ITS, the trematode mt genome appears more informative for resolving high-level phylogenies. To the best of our knowledge, this is the first study exploring the complete mt genome for the genus Notocotylus, and it offers a novel genomic resource that has important implications for trematode phylogenetics.

Interatrial septal aneurysm mimicking an atrial myxoma on multiparametric cardiovascular magnetic resonance imaging

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Interatrial septal aneurysm (IASA) appears as a localised saccular deformity usually detected during routine echocardiography or stroke evaluation. Imaging hallmarks are >15mm prolapsing motion across the interatrial septum (IAS) and identical content to blood-pool, which are in contrast to this patient. Clinical case An 81-year-old asymptomatic man underwent transesophageal echocardiographic (TEE) right atrial mass assessment revealing a well-circumscribed, mobile mass attached to the interatrial septum suggestive of myxoma. Given previously-excised renal cell carcinoma, gadolinium contrast-enhanced cardiovascular magnetic resonance (CMR) imaging was performed for mass characterisation. Mass signal intensity (SI) was distinct to blood-pool, in keeping with mass content not being blood. Cine imaging revealed an isointense, mobile mass (Figure 1, Video 1) attached to the fossa ovalis. The mass was of intermediate SI isointense to myocardium on T1-weighted, and bright and hyperintense on T2-weighted imaging. First-pass perfusion (Video 2) and early enhancement imaging demonstrated a hypointense, non-perfusing mass. The mass hyperenhanced on late enhancement imaging excluding the differential of thrombus. Imaging findings were entirely consistent with atrial myxoma. Intraoperatively, the excised mass was actually confirmed as an IASA with exquisitely tight neck. Discussion This is the first case of IASA mimicking atrial myxoma on CMR imaging. We postulate that it behaved like a non-perfusing mass as its uniquely narrow neck resulted in extremely slow flow in and out. This permitted minimal blood with contrast entry which remained ‘trapped’ within, resulting in distinct SI to blood pool, and late hyperenhancement. Left atrial pressures forced the mass into the right atrium, preventing typical lateral IASA motion. Conclusion The diagnosis of IASA is best established with TEE while CMR imaging is the reference standard imaging modality for tissue characterization. It is vital to be able to identify and differentiate such entities to avoid misdiagnosis of an IASA as a cardiac myxoma or a malignant cardiac tumour. Nevertheless, we recognize the presence of limitation of imaging in this extraordinary case. Abstract Figure 1

The effect of urine acidification on calcium oxalate relative supersaturation in cats.

There is an apparent reciprocal relationship between magnesium ammonium phosphate (MAP, struvite) and calcium oxalate (CaOx) urolithiasis incidence rate in cats. The number of struvite uroliths submitted for analysis over the past 35 years has been decreasing, with an increase in CaOx urolith submissions. Commercial diets aimed to dissolve struvite uroliths are typically acidified, and it has been suggested that dietary acidification increases urinary calcium excretion and the risk of CaOx crystallization. The objective of this study was to assess the effect of urine acidification on the relative supersaturation (RSS) of CaOx in cats, as a representation of crystallization risk. Four diets were extruded to contain identical nutrient contents, but with gradual acidification (0, 0.6, 1.3 and 1.9% sodium bisulphate substituted sodium chloride in diets A, B, C and D respectively). Thirteen adult cats were fed each diet sequentially for a minimum of 10 days. Average urine pH was 6.4, 6.2, 6.0 and 5.9 on diets A, B, C and D respectively (p < 0.0001). Struvite RSS decreased on diets inducing more acidic urine pH (p < 0.0001). Urinary calcium excretion and concentration increased with diets inducing lower urine pH (p < 0.0001), but oxalate excretion and concentration decreased (p < 0.001). CaOx RSS was not different between diets (p = 0.63). These results suggest that a lower diet base excess and resulting urine pH to support struvite dissolution do not increase the risk for CaOx crystallization in the range of urine pH representative of most commercial feline diets. Long‐term studies are needed to confirm this.

The enhanced fatty acids flavor release for low-fat cheeses by carrier immobilized lipases on O/W Pickering emulsions

Low-fat cheeses have flavor defects due to low fat content resulting in an insufficient free fatty acids (FFA) flavor release. Lipase immobilization is an attractive approach to increase the efficiency of lipid hydrolysis and FFA release. Here, α-lactalbumin (α-lac) nanotubes (NTs) formed by self-assembly of partially hydrolyzed α-lac peptides were applied as an immobilization carrier for lipases. The aim is to increase the lipase activity and compromise its flavor defects in low-fat cheeses by lipase immobilization on NTs (Lipase-NTs). Firstly, the lipase activity was improved 68% for Lipase-NTs compared with free lipase. Enzyme kinetics analysis suggested that NTs immobilization increased the affinity of lipase to substrate and reduced the potential energy barrier for enzyme reaction. Then Lipase-NTs were applied to stabilize the oil-in-water Pickering emulsion which enlarged reaction areas and improved the accessibility of lipase to substrate. The NTs-lipase emulsion system enhanced the lipase catalytic efficiency, the Lipase-NTs could hydrolyze and release 1.5 times higher amount of FFA compared to free lipases with the identical triglycerides contents by titration measurement. Lipase-NTs milk fat O/W Pickering emulsions were added in low-fat cheese to replace all the original milk fat during the cheese processing. Lipase-NTs O/W emulsion added low-fat cheese showed a twice amount of FFA release compared with normal low-fat cheese containing identical milk fat contents measured by GC-MS. This work provides the inspiration on creating flavor enhanced low-fat foods by lipase immobilization strategy which can improve the enzyme activity and promote the FFA flavor release.

Application of low-grade recyclate to enhance reactive toughening of poly(ethylene terephthalate)

This paper presents a new recognition in reactive toughening of poly(ethylene terephthalate) (PET), namely the major effect of the molecular weight of PET on the evolution of the compatibilization and crosslinking reactions with ethylene‑butyl acrylate-glycidyl methacrylate (EBA-GMA) type reactive terpolymer, and thus indirectly on its toughening efficiency. It was found that the use of highly degraded recycled PET (rPET) grades, due to the available larger number of reactive functional end groups and increased mobility of the decreased-molecular-weight chains, multiplies the impact strength of the product compared to that of original PET (oPET) with identical EBA-GMA contents. The evinced noticeable difference between the toughening behaviour of rPET and oPET is explained by morphological and interfacial factors and connected to differences in rheological behaviour as well. The reactive oligomeric rPET macromolecules form a Toughening Enhancer Interphase (TEI) around the dispersed particles. Based on systematic analyses, conclusions were drawn regarding the quality, i.e. optimal intrinsic viscosity (IV) range, and quantity of rPET to be used to obtain high-impact-strength PET blends (notched Izod impact strength higher than 40 kJ/m2) with optimised mechanical properties, being suitable even for injection moulding applications, at significantly lower terpolymer contents (10.0–12.5 wt%) than expected. Besides, the proposed new way of utilisation of PET recyclates, especially the unmarketable highly degraded fractions, is believed to give a new driving force in PET recycling.

Effects of Supports BET Surface Areas on Membrane Electrode Assembly Performance at High Current Loads

In this work, we investigated the influence of catalyst supports, particularly Brunauer, Emmett, and Teller (BET) surface area of the catalyst support materials, on membrane electrode assembly (MEA) performance. Keeping the anode catalyst layer (CL), membrane, Pt loading, and operating condition unchanged, we prepared cathode CLs using catalysts of identical Pt content (30 wt% Pt) which were supported on carbon black materials having different BET surface areas. We observed optimum cell voltage at high current load when using cathode catalyst layers prepared from catalysts supported on carbons having medium-BET surface area. High-BET surface area supports, although beneficial at low current density as well as low-BET surface area supports, led to increased voltage losses at high current load due to mass transport limitations which can be explained by the electrochemically active surface area available and water management in the catalyst layer.

Breaking Symmetry: The Asymmetries in Epigenetic Inheritance.

Symmetry and asymmetry are fundamental aspects of life. Most cells within a multicellular organism contain the same genetic information, passed on from one originating cell - the zygote; however, these cells can take on a variety of different identities, with diverse appearances and functions. A fundamental question in biology ponders how cells containing identical DNA content can take on different cell identities. Epigenetic mechanisms could be the symmetry breaking factor, as they are able to change gene expression in cells without changing the DNA sequence. While the process of duplication and segregation of DNA during cell division has been well studied, it is less understood how the epigenetic information is established and inherited in the cells within a multicellular organism. Studies of asymmetric stem cell division, where a stem cell division gives rise to a self-renewed stem cell and a differentiating daughter cell, provides a model to study how epigenetic information is maintained or changed to produce daughter cells with identical genetic information but distinct cell fates. Here, we discuss findings and ideas of how epigenetic information is maintained or changed during asymmetric cell division and the importance of this asymmetry in influencing cell fate.

The impact of camera angles in learning videos on the perception of teaching excellence and emotional connectedness of students in the creative industries

With the use of learning videos in higher education (HE) on the rise, and an increased importance assigned to the perception of teaching excellence by students in the United Kingdom (UK) and worldwide, this paper considers the impact of camera angles on students’ perception of teaching excellence and students’ emotional connectedness. Two focus groups comprising undergraduate students studying full time in subjects of the creative industries watched and discussed two videos with identical content (a presenter, presenting) but different camera angles – low-shot versus eye-level. The videos were provided as part of the course materials. The responses elicited in the focus groups suggest that an eye-level camera shot positively affects student perception of the presenter’s credibility, goodwill and professionalism in learning videos. At the same time, findings call into question the suitability of presenter-focused learning videos altogether for the teaching of creative industries subjects in HE, since students perceive that they lack sufficient presenter sparkle to enthuse, motivate and engage their audience.

ОСОБЕННОСТИ ФОРМИРОВАНИЯ ОТКРЫТЫХ ОБЩЕСТВЕННЫХ ПРОСТРАНСТВ КРАСНОЯРСКА В ЗОНЕ ВЛИЯНИЯ ОБЪЕКТОВ КУЛЬТУРНОГО НАСЛЕДИЯ

The authors consider the problem of formation of open public spaces within areas affected by the influence of cultural heritage sites. The focus here is on the historical center of Krasnoyarsk city. Relevance of the research is determined, on the one hand, by the current trend for the formation of comfortable urban environment in public open spaces. On the other hand, by the appearance of numerous implemented projects, including those in Krasnoyarsk, which have identical functional and objective content, detached from the cultural and historical context of the environment. The analysis of the “Map of areas with special land use requirements related to the protection of cultural heritage objects” in the historic center of Krasnoyarsk revealed the following characteristic morphotypes of public open spaces (genesis types) within cultural heritage areas: territory adjacent to a single cultural heritage object (protection zone of a cultural heritage object), which is part of the street; territory adjacent to a single cultural heritage object (protection zone of a cultural heritage object), which is inside the development area (yard, courtyard garden, manor house); a street formed by the facades of several cultural heritage objects on one or both sides; a square or a garden square, which is part of the architectural ensemble – an object of cultural heritage; the territory of the quarter formed by a group of cultural heritage objects, and which is a cultural heritage protection zone; a park or square within the protected historic green space. Each type is analyzed using examples, survey of protection zones of cultural heritage, the established urban planning regulations within their boundaries regarding the availability of requirements for the improvement of public open spaces. The authors touch upon the problems of landmark attractions, preservation of identity in the historical and cultural environment of the settlement. They also formulate the principles of public open space formation within influence areas of cultural heritage objects on the basis of various methodological approaches approved by the Department of Urban Planning within the School of Architecture and Design of the Siberian Federal University.

Processing, characterisation and oxidation resistance of βNiAl bond coat: Al and Zr effects

Platinum-modified-?NiAl is a bond coat (BC) material for thermal barrier coatings (TBCs) applications applied on aeroengine hardware to reduce their surface temperatures. However, it is desirable to minimize its production and material costs by the low-cost alternatives of similar performance. It has been acknowledged that the small concentration of the reactive elements (REs), such as Zr, Hf, and Y, could tremendously enhance the oxide adhesion even in some cases better than Pt modified counterparts. The aim of this study was to design and fabricate the Zr-modified-?NiAl bond coat on CMSX-4 superalloy using an aluminizing method. Moreover, the study focused on the development of a systematic understanding of underlying mechanisms behind the beneficial effects of REs. Initially, three sets of BCs were prepared: Zr-free ?NiAl (undoped), Al and Zr co-deposited in a single-step process (1SP), and Zr and Al, which were individually deposited in two processing steps (2SP): zirconizing and aluminizing. Such three sets of BCs helped to understand the processing, as well as Zr and Al effects on scale adhesion. In particular, 1SP/2SP BCs showed uniformity of Zr in the form of precipitates and networks that caused hardness enhancement. All BCs were isothermally oxidized at 1150?C for 100 hours wherein 2SP revealed the best spallation resistance, microstructural stability, and its Zr-oxide pegs were extended to substrates. In addition to the Zr effect, BC Al content was found to affect the oxide adhesion equally. Under identical Zr contents (of 1SP and 2SP = 1at %), the higher Al showed the better spallation resistance while lower Al caused the inverse effect of Zr owing to its reactive nature that was termed as over doping. Moreover, it was established that over-doping either local or into entire BC, accelerated the Al depletion that destabilized the ?NiAl into ??-Ni3Al phase. An extensive discussion is presented in the light of the observed results.

Особенности возврата после старения в сплаве магния с иттрием при легировании его самарием

It was investigated the reversion phenomenon consisting of softening after a strengthening ageing at 200 °C during from 0.5 to 128 h in a case of shortcoming annealing from 0.25 to 64 h at some higher temperature — 250 °C in the magnesium-base alloys containing the rare-earth metal — yttrium (Y), alloyed additionally by the other rare-earth metal — samarium (Sm). Both alloying elements are the rare-earth metals (REM), but belong to different groups: Y belongs to the yttrium group of REM and Sm belongs to the cerium one. It was established, that in the binary alloy of magnesium with yttrium and in the ternary alloys with the identical yttrium and diverse contents of samarium aged after the same duration for the same time the representative softening of reversion takes place indeed. As compared with the binary Mg – Y alloy and with increase of the samarium contents in the ternary Mg – Y – Sm alloys the size of the reversion increases. However, in the same case the size of the strengthening effect after ageing in the alloys increases also and it is more, than the respective reversion size.

The article studies the peculiarities of the state and confessional policy of the Russian Empire in the 19th - early 20th centuries in relation to Roman Catholics. The materials that served as the basis for the study are stored both in the Russian State Historical Archive and in the archives of Siberian cities: Tobolsk, Tomsk, Omsk, Irkutsk, Krasnoyarsk. Government orders of identical content were sent to all Siberian provincial centers, but in Tomsk they are in the best state of preservation, which gave us the opportunity to systematize them and use them for analysis. Government orders of identical content were sent to all Siberian provincial centers, but they are in the Tomsk State Archive in the best degree of preservation, which gave us the opportunity to systematize them and use them for analysis. The study revealed that the initiative to create the first Catholic parishes in Siberia belonged to the government and was dictated by the desire to remove the clergy of the Jesuit оrder from the capital...
