V. P. Kataev’s comedy Time, forward!: The artistic image of the main character in the context of the variants of the work

The article studies the variants of Valentin Kataev’s comedy Time, forward! in order to identify edits that influenced the author’s expression and the reader’s perception of the image of the main character. While researching comedy variants, it was found that the authors interested in Kataev’s work avoided the comedy Time, forward!. In our opinion, knowing about the corrections of the text of the play, Soviet critics, guided by political correctness, did not dare to engage in public polemics and literary-critical discussion around the famous writer. In the post-Soviet period, Kataev’s dramaturgy lost its relevance, did not kindle the interest of specialists. This study was conducted on the material of the comedy editions published during the author’s lifetime. Its relevance is justified by establishing the originality of the image of the main character of the main version of the work, reflecting the characters, emotions and feelings of people of its era. As part of the sample analysis it was found that by making corrections to the climactic scenes of the ending of the 1934 play, the author leaves the plot, the sequence of scenes, the system of images, the general idea of the work unchanged. During the comparison of the variants of the work, the edits made by the author to the two scenes of the finale were revealed. These scenes, connecting with the preceding scene, create a single plot and ideological and emotional node of the climax of the work. The image of the characters and the hero acquire a completely different appearance. With the appearance of comedy in public and up to the present, it has been believed that the image of the main character is a passionate and uncompromising fighter for the communist attitude to work. The edits revealed in the study in the version of the comedy of 1934, without dismissing the hero’s struggle for the result, a high pace in the socialist competition, indicate self-assertion of personality: high morality, friendly feelings. The image of the communist hero, which did not correspond to the literary and political canon, caused acute criticism and was the reason for suppressing the work. The results of the study give ground to consider the version of the play Time, forward! of 1934, a valuable source reflecting the characters, emotions and feelings of the heroes of its time.   &nbsp

The effect of various kinematics on postoperative pain after instrumentation: a prospective, randomized clinical study

Objective: To evaluate various kinematic movements on postoperative pain using a Reciproc system. Material and Methods: Fifty-six molar teeth were divided into four groups according to kinematics as follows: continuous rotation, 360° CCW – 30° CW, 270° CCW – 30° CW, and 150° CCW – 30° CW. Preoperative and postoperative pain levels using visual analogue scale (VAS), percussion pain, and analgesic intake were recorded for each subject. Postoperative pain levels at 1, 3, 5, and 7 d were evaluated. Data were analyzed statistically using the Kruskal-Walis, Mann-Whitney-U, one-way analysis of variance, and chi-square tests (p=0.05). Results: Continuous rotation resulted in more pain at Day 1 when compared with the reciprocating groups (360° CCW – 30° CW and 270° CCW – 30° C) (

Transition from hydrodynamic turbulence to magnetohydrodynamic turbulence in von Kármán flows

International audienceThe influence of an externally applied magnetic field on flow turbulence is investigated in liquid-gallium von-Ka ́rma ́n (VK) swirling flows. Time-resolved measurements of global variables (such as the flow power consumption) and local recordings of the induced magnetic field are made. From these measurements, an effective Reynolds number is introduced as Rmeff = Rm(1−α√N), so as to take into account the influence of the interaction parameter N. This effective magnetic Reynolds number leads to unified scalings for both global variables and the locally induced magnetic field. In addition, when the flow rotation axis is perpendicular to the direction of the applied magnetic field, significant flow and induced magnetic field fluctuations are observed at low interaction parameter values, but corresponding to an Alfve'n speed vA of the order of the fluid velocity fluctuations urms. This strong increase in the flow fluctuations is attributed to chaotic changes between hydrodynamic and magnetohydrodynamic velocity profiles

Modification d'un écoulement turbulent de von Kármán par un champ magnétique

La saturation de l'instabilité dynamo est liée à la rétroaction du champ magnétique sur l'écoulement qui l'a engendré. Pour étudier ce phénomène, nous avons étudié l'influence d'un champ magnétique sur un écoulement turbulent de von Kármán. Les mesures que nous avons faites montrent que les échelles turbulentes sont peu affectées par le champ contrairement aux grandes échelles de l'écoulement. On a ainsi observé une transition entre un écoulement hydrodynamique et un écoulement MHD lorsque la vitesse d'Alfvèn est comparable aux vitesses caractéristiques de l'écoulement

Tvärkraftskapacitet i pelarfotinfästningar för stålpelare : Skruvförband i pelarfötter

It is common to use different construction materials in combination such as concrete, steel, wood and glass in order to optimize buildings. The purpose of this is to reduce weight and increase load capacity, but it also facilitates assembly and reduces construction time. Steel column bases anchored in concrete foundations are an example of a combination of interaction nodes between steel and concrete elements. This report studies the friction between the lower edge of the base plate and the grout, which is a function of the normal force of the column. The friction that occurs between the square washer and the foot plate has also been examined as a result of the tightening moment. The work has placed great focus on discussing the advantages and disadvantages of the different methods for transverse force absorption in column bases. Delimitations have been made, the attachment of the column to the base plate has not been taken into account in this report, as this depends on which column cross section is selected and must be checked for the specific case. To arrive at the results, an in-depth literature study was conducted to gather information on the various issues and a calculation model in Excel was created. The calculation model was used to check how large the design load-bearing capacity is for transverse force absorption in a column base, but the checks were only made for non-prestressed joints. This is because prestressed joints also have other factors that affect the transverse resistance, outside the purpose and issue of the work. The Excel model is based on producing the results from calculation with nominal clamping force and comparing it with clamping force calculated with tightening torque. The results will be reported in the form of graphs and tables, where it will be possible to read the difference in the dimensioning load-bearing capacity for transverse force absorption in non-prestressed joints at nominal clamping force and clamping force calculated with tightening torque. The report shows a clear difference in results, where the nominal clamping force became significantly larger and this is supported by handbook on screw joints, as it is mentioned that “it is not possible to give an exact value of the coefficient of friction due to the large number of factors that affect ”, this means that the impact on the clamping force will be large.Det är vanligt förekommande att man använder sig av olika konstruktionsmaterial i kombination med varandra såsom betong, stål, trä och glas för att på så sätt kunna optimera byggnader. Syftet med detta är att minska vikt och öka belastningskapacitet, men det underlättar även montaget och minskar byggtiden. Pelarfötter av stål förankrade i betongfundament är ett exempel på en kombination av samverkansknutpunkter mellan stål och betongelement. I denna rapport studeras friktionen mellan underkant fotplatta och undergjutning, som är en funktion av pelarens normalkraft. Även friktionen som uppstår mellan fyrkantsbrickan och fotplattan kommer att undersökas som ett resultat av åtdragningsmomentet. Arbetet har lagt stor fokus på att diskutera för- och nackdelar med de olika metoderna för tvärkraftsupptagning i pelarfötter. Avgränsningar har gjorts, pelarens infästning till fotplåten har inte beaktats i denna rapport, eftersom detta är beroende av vilket pelartvärsnitt som är valt och måste kontrolleras för det specifika fallet. För att komma fram till resultaten utfördes en fördjupad litteraturstudie för att samla ihop information om de olika frågeställningarna och en beräkningsmodell i Excel skapades. Beräkningsmodellen användes för att kontrollera hur stor den dimensionerande bärförmågan är för tvärkraftsupptagning i en pelarfot, men kontrollerna görs endast för icke förspända förband. Detta eftersom förspända förband även har andra faktorer som påverkar tvärkraftskapaciteten, utanför arbetets syfte och frågeställning. Excel-modellen går ut på att ta fram resultaten ur beräkning med nominell spännkraft och jämföra den med spännkraft beräknad med åtdragningsmoment. Resultaten redovisas i form av grafer och tabeller, där man kan läsa av skillnaden i den dimensionerande bärförmågan för tvärkraftupptagning i icke förspända förband vid nominell spännkraft och spännkraft beräknad med åtdragningsmoment. Rapporten visar en tydlig skillnad i resultat, där den nominella spännkraften blev betydligt större och detta stöds av handbok om skruvförband, då det nämns att “det är inte möjligt att ge ett exakt värde på friktionskoefficienten på grund av det stora antalet faktorer som påverkar”, detta medför att inverkan på klämkraften blir stor

Development of a Methodology for Forecasting the Sustainable Development of Industry in Russia Based on the Tools of Factor and Discriminant Analysis

The problem of sustainable development is one of the central issues on the agenda of the global community. However, it is difficult to assess the pace and quality of sustainable development of individual economic systems—in particular, industry—due to the lack of a unified methodological approach. In this regard, the following research goal was formulated—to develop and test a methodology for forecasting sustainable development by using statistical tools. The achievement of the goal was facilitated by the application of formalization methods, factor analysis, discriminant analysis, the method of weighted sum of the criteria, and the method of comparison. The results of the study are new scientific and practical solutions that develop the ability to diagnose economic systems for the transition to environmentally friendly production. Firstly, methodological solutions are proposed to assess the nature of the transition of industry to sustainable development (low, medium, or high rate). The methodology is based on the proposed aggregated indicator of sustainable industrial development based on the results of factor analysis (by the method of principal components). As a result, the patterns of sustainable development of the extractive and manufacturing sectors of the Russian economy are revealed. Secondly, integral indicators of economic, environmental and social factors of sustainable development are calculated, and classification functions for each type of industrial transition to sustainable development (low, medium, or high) are formed through discriminant analysis. Scenarios of industrial development are developed, taking into account the multidirectional trajectories of the socioeconomic development of the country. Thirdly, the DFD model of the process of scenario forecasting of sustainable industrial development is formalized, reflecting the movement of data flows necessary for forecasting sustainable industrial development. It is revealed that the manufacturing industry is expected to maintain a low rate of transition to sustainable development. On the contrary, for the extractive industry, if efforts and resources are concentrated on environmental innovations, average transition rates are predicted. The uniqueness of the proposed approach lies in combining two types of multivariate statistical analysis and taking into account the indicators that characterize the contribution of industrial enterprises to sustainable development
