Estimating Ship Underwater Radiated Noise from Onboard Vibrations
Authors: Cintosun Esen , Gilroy Layton
Published: October 2021

The acoustic signature of an Orca-class training vessel (Patrol Craft Training, PCT) Moose from the Royal Canadian Navy (RCN) was measured at the RCN’s Patricia Bay acoustic range on Vancouver Island, British Columbia, Canada. The acoustic range trials included accelerometer measurements on the ship hull and in the engine room and hydrophone measurements at approximately 100 m from the ship. The trials were carried out at the ship speed range of 3 to 20 knots. The test data from all the trial runs was used to derive, evaluate and validate the method of estimating ship underwater radiated noise from onboard vibrations. In the investigation, the runs were split into two sets: a training set and a testing set. A least squares approximation, AQV (average quadratic velocity) SL (source level) correlation, was then applied to the training set data to formulate a transfer function to estimate the underwater radiated noise from onboard vibrations. The AQV is calculated from accelerometer measurements (vibration levels) and SL is obtained from the hydrophone measurements. The third octave frequency band (from 10 Hz to 10 kHz) SL estimations of the testing set runs (using the transfer function and AQV) are within 1 to 3 dB of SL from the hydrophone measurements. This study demonstrates a capability of monitoring underwater radiated noise from ships using only onboard vibration levels which may be of interest for future projects relating to the reduction of shipping noise against a threshold in acoustically sensitive environments.
Technical Analysis of Ocean Towing Evolutions
Authors: Eckhardt Bartley , Fridline Daniel , Burke Richard
Published: October 2021

Ocean towing in general, and non-routine tows in particular, present unique technical challenges to towing vessel owners/operators, salvors, the offshore oil/gas and wind industries, and others. When such tows “go wrong”, the harm to human life, property and/or the environment can be significant.

The authors have drawn from their work on the Towing Safety Advisory Committee’s investigation of the grounding of the MODU Kulluk to present methods and considerations in analyzing ocean towing evolutions, both “routine” and “non-routine”. (TASK 14-01)

The methods and considerations presented should be employed in advance of a towing evolution, but can be used in accident reconstruction and forensic analysis when an evolution has failed. The methods presented are iterative, and consider 2 x 6 degree freedom of motion (of the towing vessel(s) and towed vessel respectively) and characteristics of the towline, and facilitate determination of:

Worst Case Conditions.

Extreme Towline Tension (ETT) as a function of sea state and speed.

Limits of the Tow (Go-No Go Criteria).

Recommended Catenary Length as a function of sea state and speed.

Size and Selection of the Towing Vessel and Gear, including:

Required Bollard Pull.

Required Strength, Characteristics and Condition of the Towline.

Limits and Set Points of the Towing Winch, Automatic or Manual.

Required Strength and Characteristics of the Synthetic Emergency Towline and its methods of deployment and connection.

Working Load Limit (WLL) of the Shackles, Delta Plate and Attachment Points.

Required Strength and Characteristics of Bridles, Pendant and Surge Gear/Shock Lines.

The authors further explore the implications of single point failure modes, redundancy in gear and towing vessel(s), high cycle fatigue, and strain monitoring.
Predicting the Powering Performance of Different Vessel Types using an Open-Source CFD Propulsion Framework
Authors: Windén Björn
Published: October 2021

CFD is a useful tool for ship designers looking for accurate predictions of the fuel efficiency achieved by a certain combination of hull, propeller and Energy Saving Devices (ESDs). Such predictions are key to meeting ever-increasing demands for reductions in emissions. However, CFD simulations of propeller-hull interaction can be very costly in terms of computational effort due to the need to resolve the unsteady flow around the rotating propeller.

A popular approach to alleviate this cost, that has seen much practical use in industry, is the use of body forces (momentum sources) to represent the rotating propeller. There are many ways to describe the body force distribution in the fluid for a certain propeller and there are many options for what flow solver to use. In a previous meeting of the Society, an open-source framework for easily creating coupled solvers using an arbitrary combination of models was presented.

Here, one of these coupled solvers is used to predict the local flow behind the propeller, as well as integral coefficients indicating performance, of four different vessels: a bulk carrier fitted with an Energy Saving Device, a fast container ship, a tanker and a fully appended twin-screw navy destroyer. All simulations are compared to available experimental data. Conclusions are drawn based on the success of the coupled solver to predict the local flow behind the propeller for each individual hull and how this relates to the vessel type and the local stern geometry.

Published: October 2021

In recent years, the shipbuilding industry has been incorporating different technological innovations that adapt innovative techniques such as image correlation for 3D reconstruction, reduced order modeling methods for digital twins, pixel amplification techniques to measure vibrations, among other methodologies. The advancement of these methodologies help to obtain visual resources that allow a better understanding of a given phenomenon, which complements the results found numerically, analytically or experimentally. The present study collects data from different configurations of ship propulsion plants, which are based on real operating conditions. The operating conditions are given for fishing vessels; the "navigation" condition is selected as being the most frequent and the "fishing operation" as being the most energetically critical. These conditions are attached to the choice of the ship's propeller. For the propeller, the diameter, the number of blades and the length of the drive shaft from the main engine position to the propeller are considered. Three engine power levels (low, medium and high) are selected, represented by 300, 850 and 1300 HP engines. The aforementioned operating conditions are used to calculate the efficiency of the propulsion plant, obtaining several combinations. Furthermore, these configurations are expressed by means of Sankey diagrams and illustrations of the plant configurations in 3D using WebGL and Threejs libraries. Complementarily, these data are observed in an online simulator called "ShipSim", using "html" coding.

Published: October 2021

Offshore wind energy is developing rapidly in the United States, particularly off the East coast, which has an extensive continental shelf and where the water depths are such that wind turbines founded directly on the seabed are the most attractive. Of the various foundation configurations that are feasible, it is the monopile that is expected to be most widely used. Another feature of the US East coast is that it is hurricane-prone region, which poses some unique challenges to designers. This paper summarizes research work undertaken to investigate how the role of modern optimization techniques can contribute to the design of such installation and does not establish any realistic project related implications. The project addresses the design of a 15 MW turbine, which represents the upper limit capacity of currently available wind turbines.

Authors: German O. Yu. , Bratchenko a. m. , Lytovchenko Ye. O.
Published: October 2021

Aim. Obtaining and analysis of cytogenetic parameters in meristem cells of Allium cepa L. seedling sprouting from unirradiated seeds, while germinating them with seeds, that were exposed to γ-radiation in different doses. Methods. Cytogenetic analysis included analysis of mitotic activity, anaphase method of chromosome mutations, nucleolar analysis. The F-test was used to compare the control and experimental samples. Results. The formation of the bystander effect is shown in the case of joint germination of irradiated and non-irradiated seeds. The severity of bystander effect increases with increasing irradiation dose. Conclusions. Irradiation of seeds with a dose of gamma radiation of 40 Gy causes the formation of radiation hormesis by the criterion of mitotic activity in the root meristem cells of seedlings, and the irradiation with a dose of 10 Gy does not affect the level of cell proliferation. The bystander effect formation occurs during the joint germination of intact and irradiated seeds as an increase in the level of mitotic activity, and an increase in the number of chromosomal mutations.

Keywords: bystander effect, γ-radiation, meristem, mitotic activity, chromosomal abnormalities, micronuclei.

Published: October 2021

Aim. Aim of the study was to microscopically investigate the interaction of Acholeplasma laidlawii var. granulum 118 with the target plant Medicago sativa, as well as to determine the role of Rhizobium meliloti strains with natural and defective polysaccharides in the plant’s resistance occurrence. Methods. Cultivation of plants and their inoculation with bacteria was performed under conditions of microvegetation experiment. The study of the ultrastructure of alfalfa roots and nodules was carried out with both light and electron microscopy. Results. The rhizobial mutant strain, defective in the synthesis of lipopolysaccharides, more often formed atypical nodules on M. sativa, which aged faster. In the variant with double inoculation of alfalfa with rhizobia together with acholeplasma changes in the morphology of the lateral roots of plants, as well as deformation of the nodules were observed. Conclusions. Results of this study indicate not only the ability of phytoplasmas to penetrate the root system and migrate to plant aboveground organs, but also demonstrate the possibility of their presence in the nodules formed by rhizobia.

Keywords: Mollicutes, acholeplasma, rhizobia, mutant, lipopolysaccharides.

Published: October 2021

Aim. Study of the dynamics Gentiana lutea L. plant growth processes in vitro depending on the light regime changes of their cultivation in order to develop a scheme to increase their adaptive potential. Methods. Methods of plant cultivation in vitro, biometric method, as well as ANOVA variance analysis and middle group analysis in pairs using the Tukey test (Tukey test) were used. Results. It is shown that the cultivation of G. lutea plants in vitro using 25 W/m2 light flux intensity in the region of photosynthetically active radiation and the ratio of blue (Eb): green (Eg): red (Er) ranges = 41.8%: 42.7 %: 15.5% triggers non-specific photomorphogenesis reactions for intact plants, which lead to poor root system development, stem elongation, formation of small leaves with a thin leaf blade, overall low productivity and low adaptation potential of G. lutea plants to ex vitro and in situ conditions. Increasing the light flux intensity to 44 W/m2 and increasing the red wave proportion up to 20.3% allows not only to improve the bioproductivity of G. lutea plants which are cultivated in vitro, but also to increase the coefficient of microclonal reproduction without the additional use of exogenous growth regulators. The greatest growth of the aboveground and underground parts, increase in effective leaf surface are observed in vitro plants during cultivation at 135 W/m2 light flux intensity and spectral composition Eb: Eg: Er = 29.5%: 32.5%: 38.0%. Conclusions. It is possible to improve plant bioproductivity by changing the light conditions of plant cultivation in vitro, and, accordingly, to increase the adaptive potential to ex vitro and in situ conditions.

Published: October 2021

Aim. Optimization of conditions for genetic transformation of new promising genotypes of winter bread wheat (T. aestivum L.) by in planta method. Methods. Agrobacterium-mediated transformation by in planta method using the strain AGL0 and vector construct pBi2E. Results. The influence of air temperature, optical density of cells of agrobacterial suspension, inoculation day and composition of inoculation medium on the frequency of obtaining transgenic plants of new winter wheat genotypes was studied. The dependence of the frequency obtaining of transgenic plants from environmental conditions, in particular temperature, has been established. It was found that the temperature regime of 20-22°C provided the largest number (4.8%) of wheat transformants, and when the temperature is reduced to 16-18°C there is a decrease in the efficiency of T-DNA transfer into the plant genome and the lowest frequency of transformation (0.7%). Conclusions. The largest number of transformants was obtained using a inoculation medium without sucrose, the optical density of cells of the agrobacterial suspension of 0.6 op.od. and inoculation on the third day after castration of ears.

Study of transgen functionality in T2 biotechnological plants of winter wheat on the sign of osmoresistance
Authors: Komisarenko A. G. , Mykhalska S. I. , Kurchii V. M.
Published: October 2021

Aim. To investigate the functionality of the transgene in the seed generation (T2) of genetically modified winter wheat plants (Triticum aestivum L.) in terms of productivity in conditions of normal and insufficient water supply. Methods. Determination of yield structure and protein content. Results. The indicators of productivity of control and T2 biotechnological plants under normal growing conditions and water deficit are analyzed. The quantitative composition of protein in the conditions before and after osmotic stress and in the period of rehydration was determined. Conclusions. It is shown that under the action of water deficit there is a decrease in productivity for all studied plants. In this case, genetically modified plants had an advantage in the main elements of the crop structure over the original form under both analyzed growing conditions. It was found that under normal conditions of hydration, the amount of protein in the studied plants did not differ significantly. An increase in its content in control plants under the action of osmotic stress was recorded, which may indicate the synthesis of stress response proteins. Decreased protein content during rehydration may indicate the passage of normal metabolic processes.

Keywords: Triticum aestivum L., biotechnological plants, proline dehydrogenase gene, structural analysis of yield, osmostability.
Strategy for searching potential partner genes of Drosophila melanogaster Sws gene
Authors: Horin M. Ye. , Matiytsiv N. P.
Published: October 2021

Aim. The Drosophila swiss cheese (sws) gene is a mammalian ortholog of neuropathy target esterase (NTE or PNPLA6). This protein is involved in the functioning of the nervous system and causes some kinds of polyneuropathy with the mechanism unknown. Genes-interactors of the sws gene should be found to investigate the cellular mechanism of SWS/NTE-dependent neuropathy formation and to find out what signaling pathways SWS is involved in. Methods. The search was done in the Drosophila database – Flybase, in the NCBI (Gene) database to search for orthologs, and the String web resource was used in the case of potential protein interactions. Results. Only four experimentally identified genes-interactors were listed in the Flybase. Based on the expression changes data of 28 genes at PNPLA6 silencing, a theoretical search for the corresponding orthologs in Drosophila was done. The in silico assay predicted 10 proteins that are probably functioning within one metabolic pathway. Conclusions. The methods applied gave us a wide list of genes that can interact with sws at different levels: from the expression pattern to the phenotype. Therefore, 25 potentially partner genes were selected to verify the genetic interaction of these genes in vivo.

Statistical analysis of cytogenetic data
Authors: Atramentova L. A.
Published: October 2021

Using the data obtained in a cytogenetic study as an example, we consider the typical errors that are made when performing statistical analysis. Widespread but flawed statistical analysis inevitably produces biased results and increases the likelihood of incorrect scientific conclusions. Errors occur due to not taking into account the study design and the structure of the analyzed data. The article shows how the numerical imbalance of the data set leads to a bias in the result. Using a dataset as an example, it explains how to balance the complex. It shows the advantage of presenting sample indicators with confidence intervals instead of statistical errors. Attention is drawn to the need to take into account the size of the analyzed shares when choosing a statistical method. It shows how the same data set can be analyzed in different ways depending on the purpose of the study. The algorithm of correct statistical analysis and the form of the tabular presentation of the results are described.

Published: October 2021

Aim. Main aim of this research was the evaluation of theoretical bioethanol yield (per ha) from hexaploid giant miscanthus (Miscanthus х giganteus) and further comparison with conventional triploid form as well as with other bioethanol crops. Methods. Several mathematic functions were determined that describe yearly yield dynamics and equations, which were used in calculations of theoretical bioethanol yield. Results. The theoretical bioethanol yield was evaluated for different hexaploid miscanthus lines. The most productive in terms of ethanol yield were lines 108 and 202, from which potential bioethanol yield was found to be higher than in control line (6451 L/ha) by 10.7 % and 14.2% respectively and can reach 7144 L/ha and 7684 L/ha. Conclusions. It was determined that the most productive lines of polyploid miscanthus (lines 108 and 202) are able to compete with other plant cellulosic feedstocks for second-generation bioethanol production in Ukraine. However, these lines show bioethanol productivity than sweet sorghum, in the case when sweet sorghum is processed for obtainment of both first- and second-generation bioethanol.

Published: October 2021

Aim. The aim of the study is to create a selection material of oilseed flax with high cold resistance by hybridization. Methods. To achieve this goal, the following methods were used: simple (single and reciprocal) and complex (backcross, triple, four- and five-component step) crossing. Promising plants for cold tolerance donors were involved in the selection process. Creations of crossbreeding combinations were created on the basis of hypotheses of multiple gene action and heterosis. Results. The results of the study are the creation of hybrids of oilseed flax with high cold resistance. Conclusions. It was found that paired crosses were less effective compared to different types of complex. The formative process of complex crosses contributes to the increase of adaptive signs and properties to hypothermia. The best donor of cold resistance was the Sideral variety.

Published: October 2021

Aim. The aim of the study was to investigate allelic variability of high-molecular-weight glutenin loci Glu-A1, Glu-B1, Glu-D1 in Ukrainian winter wheat landraces and obsolete cultivars Triticum aestivum L. Methods. Allelic diversity at the Glu-1 loci were analyzed in 54 collection accessions, including 41 landraces (Krymka, Banatka, Girka, Theyka and others), and 13 first breeding cultivars that were developed in the beginning of the last century by selection from local wheat. Method of SDS-PAG electrophoresis according to Laemmli was used for fractionation of HMW glutenin subunits. Results. A total 11 alleles at the Glu-1 loci were identified, including 3 alleles at the Glu-A1 (a, b, c) and Glu-D1 (a, b, d) loci, and 5 – at the Glu- B1 (c, u, an, aj and subunit 9). Differences in frequencies of glutenin alleles were revealed. Conclusions. In the gene pool of Ukrainian winter bread wheat landraces the most widespread alleles were Glu-A1a (43.3 %), Glu-A1b (40.5 %), Glu-B1c (58 %), Glu-B1u (23 %), Glu-D1d (48.6 %), Glu-D1a (47.2 %). All these alleles (except of the Glu-D1a) are also predominant in the gene pool of modern commercial Ukrainian cultivars. A distinctive feature of Ukrainian landraces are the rare allelic variants of the Glu-B1 locus, which encode the subunits 1By9 and 1By8 (allele Glu-B1aj).

Published: October 2021

Aim. Over the past decade, telomere biology has become an important topic in the field of human reproduction.We focused on the relationship between relative telomere length (RTL) and tendency to early pregnancy loss (EPL) in humans. Methods. RTL was measured in DNA isolated from the blood samples using a real-time polymerase chain reaction approach. RTL was examined in control group (C) (N=209) – women (CW) (N=107) and men (CM) (N=102) who had healthy pregnancies with no history of infertility or miscarriage, and in group with EPL (N=445) – women (EPLW) (N=223) and men (EPLM) (N=212) who had single or more EPL. RTL data were analyzed by gender and reproductive history. Results. Women (CW+EPLW) have significantly higher RTL that men (CM+EPLM) (1.74±0.06 in women and 1.40±0.05 in men, P=0.000053). Average RTL were significantly lower in CM compared to CW (CW: 2.27±0.12 versus CM: 1.15±0.08, P=0.0000001), and were similar in EPLW and EPLM (1.50±0.06 in EPLW and 1.53±0.06 in EPLM, P=0.47). The EPLW group had significantly lower RTL than control (EPLW: 1.50±0.06 versus CW: 2.27±0.12, P=0.0000001). Average RTL were significantly lower in CM compared to EPLM (1.15±0.08 in CM and 1.53±0.06 in EPLM, P=0.00006). Conclusions. Women with no history of EPL have longer telomere than men. Woman with EPL have shorter telomere that women without miscarriage. In EPL group women and men have similar telomere length.Keywords: telomeres, RT-PCR, gender, early reproductive loss.

Aim. The prognosis of the reproductive function of women with pregnancy loss is complex and partly based on the results of karyotyping of material of reproductive loss. We studied the features of the karyotype of material of EPL depending on the reproductive history of women with an emphasis on viable and non–viable karyotype abnormalities(KA). Methods. Banding cytogenetic and interphase mFISH with the centromeric probe panel for chromosomes 13, 14, 15, 16, 17, 18, 21, 22, X and Y were used. Results. Were examined 1734 cases of material EPL. Abnormal karyotype was set in 39.3% of cases. The frequency of KA is not significantly different in the material of EPL obtained from women with different reproductive history, namely: first pregnancy loss– 38.9% RPL – 38.2% and SPL – 41.0% (P> 0.05). In the group with RPL significantly more frequent non–viable KA and less viable KA, compared with a group of SPL namely 70.15% and 29.85% compared to 58.85% and 41.15% respectively(P<0.025). Conclusions. The contribution of different KA in genesis of the EPL depends on the reproductive history of women, namely women with RPL significantly increases the proportion of non–viable KA and reduced contribution viable KA compared with a group of SPL.

Authors: Avksentieva O. O. , Batueva E.D.
Published: October 2021

Aim. Study of the effect of red (660 nm), green (530 nm) and blue (450 nm) light on the growth processes and the state of the antioxidant system in the axial organs of seedlings of pea plants. Methods. Etiolated seedlings of pea Maecenat variety were irradiated with selective light with different spectrum of RL (660 nm), GL (530 nm), BL (450 nm) to activate photoreceptor systems of plants. In 10-day-old seedlings, growth response was determined – linear growth and biomass accumulation, as well as indicators of antioxidant system – hydrogen peroxide content and activity of oxidases – catalase and nonspecific peroxidase in axial organs of seedlings: in the aboveground part and roots. Results. Irradiation of the RL and the GL stimulates the accumulation of seedling biomass in the aboveground part and roots. BL inhibits the growth response of seedlings. The maximum stimulating effect is shown by the GL. The state of the antioxidant system in etiolated seedlings is characterized by organ specificity. Under the action of selective light, the content of the main form of ROS – hydrogen peroxide and shoots and in the roots, significantly stimulates the activity of catalase and peroxidase enzymes in the aboveground part of the seedling and is inhibited in the roots. The maximum effect in the aboveground part is shown by the GL, in the roots of the RL and the BL. Conclusions. The established effects of selective light irradiation are manifested differently in the aboveground and underground parts of seedlings. Possible mechanisms of connection of a condition of antioxidant system with separate aspects of signaling in photomorphogenesis of plants are discussed.

Keywords: Pisum sativum L., selective light, RL (660 nm), GL (530 nm), BL (450 nm), growth reaction, axial organs, H2O2, catalase, peroxidase.
L’américanité, ou la destruction tranquille du patrimoine
Authors: Mathieu Félix , Charron Catherine
Published: October 2021

Le patrimoine est en abîme. Il souffre d’un « mal » profond, difficile à cerner. Comment expliquer ce phénomène en le situant plus précisément dans le sillage de la trajectoire sociopolitique du Québec ? Afin de répondre à ce questionnement des plus préoccupants, cet article propose une (hypo)thèse forte qui ne pourra toutefois pas être démontrée au sens premier du terme : c’est pourquoi nous le qualifions d’essai de théorisation. Son objectif consiste à soulever une piste de réponse qui nous paraît féconde, et que nous espérons ensuite voir débattue par la communauté tant épistémique que praticienne. Cette thèse s’articule ainsi : le « mal patrimonial », au Québec, s’explique principalement par la prégnance de l’américanité – comme pensée forte – pour imaginer l’être, le passé et le devenir de la société québécoise. Ce faisant, la nation québécoise en est venue à s’imaginer par l’unique prisme d’une radicale modernité, rejetant par principe toute intentionnalité collective particulière. C’est parce qu’elle associe plus ou moins (in)consciemment le patrimoine aux traditions, puis le traditionalisme aux sociétés d’Ancien régime, que l’américanité est à l’origine de l’abîme du patrimoine et de l’acte de patrimonialisation.
Investigation of an Unrecorded Indigenous Copper Kettle Burial at Cap St-Louis, New Brunswick
Authors: Tremblay Eric
Published: October 2021

This article is the result of an investigation about an unrecorded archaeological find in Cap St-Louis (New Brunswick) in 1940. The find was a Copper Kettle Burial as it was practiced by the Mi’gmaq during the 16th and 17th century. No proper recording or conservation efforts had been deployed then since the Copper Kettle Burial was not well known at the time. Most of the funerary objects have been lost or given as mementos to family or friends of finder. The site has been eroded since 1940 but this investigation permitted Parks Canada to assign it a provenience number and ensure proper protection in the future for the site in case other burials appears at this location. Some objects are located at the Musée Acadien de l’Université de Moncton. In the spirit of reconciliation, the university will give back these funerary objects to the Mi’gmaq of New Brunswick.
Le Musée Huron-Wendat
Authors: Bernardot Hélène
Published: October 2021

Cette étude muséologique sur le Musée Huron-Wendat explore les enjeux impliqués dans la gouvernance autochtone d’une institution muséale. Elle examinera comment la culture et l’identité de la Nation Huronne-Wendat est représentée par le musée, et comment les visiteurs la comprennent et interagissent avec elle. Cet article vise ainsi à combler des lacunes dans l’étude des musées des Premières Nations au Québec, qui ont jusqu’à aujourd’hui peu retenu l’attention des chercheurs. Il comprendra une présentation du musée lui-même, qui sera suivie des résultats d’une étude de terrain visant à comprendre quelles sont les pratiques de représentation du patrimoine Wendat au sein de leur musée et comment la communauté ainsi que les visiteurs du musée dialoguent avec celles-ci.
“Do as good as abroad”: the resorts of the south coast of Crimea during the World War I
Authors: Karagodin Andrey Vasil'evich
Published: October 2021

This article raises the virtually unstudied in Russian historiography topic on the development of resorts of the south coast of Crimea during 1914–1919, the World War I, and revolutionary events of 1917. The situation in the Russian tourism sector in the years of World War I is consonant with the current situation caused by the coronavirus pandemic. The Russian people, who prefer vacationing abroad, descended on the Russian resorts, which were not ready for such turn of events. This caused a public discussion on the topic of improving the Russian health treatment facilities, the materials on which are barely introduced into the historical discourse. The theme of economic and sociocultural development of the south coast of Crimea in the early XX century, which until recently was farmed out to historians and art historians, remains relevant. In the course of working on this article in the libraries and archives, the author reveals and introduces into the scientific discourse various types of sources that can shed light on the transformation of the south coast of Crimea after the beginning of the World War I. The three most promising vectors for further development of the topic are outlined: work with verbatim reports of the Congress on the improvement of health treatment facilities (1915), advertising materials and documentation of the newly established resort towns Laspi and Foros, as well as the sources of historical memory (memoirs, correspondence, diaries), which reflect the everyday life in the resorts of the south coast of Crimea during the wartime and revolutionary period.
“Representation of people” of the Russian Empire of the early XX century in memory and fate of members of the Duma
Authors: Selunskaya Natal'ya Borisovna
Published: October 2021

Russian history of the early XX century marks a landmark event – establishment of the State Duma, which was the “representation of people” in the government system of the Russian Empire and the emergence parliamentarism in Russia. The “memory studies” methodology elucidates the dramatic history of the State Duma by describing behavioral patterns of the deputies and motivation for their actions, as well as offers a new perspective on this institution of power as the image imprinted in memory of the deputies: diary notes during sessions of the Duma, and memoirs written abroad. The historians dealing with the “memory studies” genre bring the image of “era” to the forefront: historical events in the perception of their contemporaries, participants, witnesses, as well as individual experience, rational assessments, and emotional experiences captured in the diaries, correspondence, and memoirs, which are the sources for studying historical memory. These texts trace the dependence of life path of the deputies, representatives of the Russian political elite, and their personal stories on the fate of the Russian Empire. Such “dependence” is manifested in the chain “memory-identity-trauma”, which is the focus of attention in “memory studies”.
The establishment and functionality of government bodies responsible for implementation of privatization during the 1991–1993
Authors: Salnikov Andrei
Published: October 2021

This article examines the establishment of government structures responsible for conducting privatization, as well as the rapid evolution that they underwent overt the period from 1991 to 1993. The struggle of various political forces resulted in creation of the two departments responsible for conducting privatization – the State Property Committee and the Federal Agency for State Property Management. The author elucidates the factors of their creation, analyzes the aspects of the political struggle between various Russian elite groups that influenced the structure of privatization bodies. Analysis is also conducted on the practical activity of both “privatization” bodies and the State Property Committee and the Federal Agency for State Property Management during the 1991–1993. The following conclusions were made: 1. The bodies responsible for privatization were created for political reasons, and despite the outlined objectives, were not assigned the task of effectively selling state property. 2. The State Property Committee was formed as part of I. S. Silaev’s government for engaging enterprises from the union jurisdiction to the Russian jurisdiction. 3. The Federal Agency for State Property Management was established to obstruct the government of I. S. Silaev in managing privatization; however, due to imminent resignation of this government and formation of the new Yeltsin-Gaidar government with the dominant position held by another elite group – “young reformers” – it was no longer relevant all the way until 1993.    
Towards the stability of criminal law: deliberation on certain starting points
Authors: Trakhov Aslan Ismailovich , Beshukova Zarema Muratovna
Published: October 2021

This article is dedicated to the problem of overcoming imbalance between dynamism and stability of the current criminal legislation. Analysis is conducted on the gradation of amendments to criminal legislation for the period from 1997 to the first half of 2021; this includes the changes in criminal law based on objective reasons, as well as unsubstantiated criminal law novelties. There author determines three scenarios of further development of the national criminal legislation: accelerated (uneven), intensive, and transformational. It is stated that the most optimal choice is the intensive scenario. However, regardless of which scenario would be chosen, the starting point towards the stability of criminal law consists in creation of the adequate conceptual-categorical apparatus of criminal law, namely, the legislative definition of certain evaluative concepts. Based on the examples of case law, the author justifies the expediency of legislative consolidation of the definitions of certain evaluative concepts. The following conclusions were made: 1. Legislative clarification of the scope and content of evaluative concepts requires using the most abstract method for formulation of regulatory directions instead of casuistic method. 2. In the event of practical implementation of the intensive scenario for the development of criminal law, the criminal law norm that contains definitive apparatus should be placed in the new Chapter 13 of the Criminal Code of the Russian Federation, and specifically outside the Special Part of the Criminal Code of the Russian Federation. This requires the introduction of the new “Conclusive Part”. 3. In the event of practical implementation of the accelerated (uneven) scenario or transformational scenario of the development of criminal law, most optimal is to place the criminal law norm containing the conceptual apparatus solely in the General Part of the Criminal Code.

Authors: Kosorukov Artem Andreevich , Osipov Vladimir Sergeevich
Published: October 2021

The subject of this research is the online and offline mechanisms of sociopolitical mobilization of youth, namely digital grouping and formation of digital communities, as well as the opposition-mobilization model of information distribution developed by E. V. Brodovskaya and A. Y. Dombrovskaya. This model was tested on the open statistical databases provided by “Telegram Analytics” and “Google Trends”, which revealed the key patterns and differences in the protest events that unfolded in Moscow (July 14 – September 29, 2019), Minsk (August 9 – November 19, 2020), and Hong Kong (June 12, 2019 – July 1, 2020). The novelty of this research lies in the following: 1) application of the model of information distribution developed by E. V. Brodovskaya and A. Y. Dombrovskaya to the data array obtained by the author from the statistical database of “Telegram Analytics” and “Google Trends” regarding the protest events in Moscow, Minsk, and Hong Kong; compilation of weekly charts of the activity of protest Telegram channels and building histograms based on them, with visualization of their peak mentioning in other Telegram channels during the indicated periods. The author formulates recommendations on how to avoid the escalation of conflict during protest actions, taking into account mobilization mechanisms on the basis of Telegram channels.
Interactive Environment and Virtual Reality to Reconstruct Manufacturing Processes (Moscow Trekhgorny Brewery in the Late 19th - Early 20th Centuries).
Authors: Gasanov Arsenii
Published: October 2021

The article studies the creation of virtual reality interactive environments as a form of presenting historical 3D-reconstruction results. This approach provides for restoring not only static objects such as architectural appearance and interiors but also dynamic ones. The latter are industrial processes of the past, for instance. The manufacturing building of Tryokhgorny brewery (the biggest in the Russian Empire) was an object for virtual 3D-reconstruction. The article describes the source base and the reconstruction of indoor spaces of the brewery building in the late 19th - early 20th centuries and reconstructs brewing processes as well. The result of the work done is the creation of a virtual reality application with historical sources verification and information tips systems included. The author tests technologies of mechanical animation and particle systems and forms interactive environment logic by means of basic software “Unreal Engine 4” through the visual programming interface “Blueprints”. The virtual environment created lets users take on the role of a brewery worker and make necessary brewing operations in virtual reality.
Le débat sur l'extension de l'obligation vaccinale en France: analyse discursive et argumentative d'une parole "éclatée"
Authors: Ravazzolo Elisa
Published: October 2021

French vaccination policy has recently been the subject of much debate on the advisability and risks of extending the vaccination obligation. The legal provision introducing 11 compulsory vaccines on January 1, 2018 called for the mobilization of different groups of actors (institutional representatives, doctors, researchers, parents’ associations, representatives of pharmaceutical companies, citizens, etc.) often speaking in different arenas. Indeed, if political debates and parliamentary committees are invested by institutional actors and experts, discussion forums and social networks constitute the privileged place of expression of non-institutional actors or lay-experts, who use this space for discussion above all to express their scepticism or their reluctance over vaccines. The objective of this contribution is to analyse on the one hand the forms and mechanisms put in place in the construction of the debate on this social issue and, on the other hand, to highlight the linguistic and argumentative specificities of the discourse of pro-vaccinalists and of the anti-vaccinalists, categories which bring together different actors.
DORA in practice
Authors: Ruud Kenneth
Published: October 2021

Although the San Fransisco Declaration of Research Assessment (DORA) provides guidelines for best practice in research assessment, many institutions and reviewers at first find it difficult to ensure that the guidelines are adopted in their own evaluation committees and evaluation work. In this talk, I will share some suggestions for how institutions can ensure that the DORA guidelines are used by their evaluation committees. Based on personal experience as a chair of review panel for organizations that have signed the DORA declaration, I will also share some experiences on how one as chair may facilitate the use of the DORA best practice in evaluation work, as well as how this influences the evaluation process.
