MINERAL COMPOSITION OF SOME LATGALE LAKE SEDIMENTS
Authors: Tretjakova Rasma , Karpovičs Andris
Published: June 2019

Our research is focused on sedimentological conditions and postdepositional changes of recent fine grained lake sediments. We used bulk sediment mineralogical composition and grain size distribution as indicators to identify sediment source areas and possible changes during Holocene. We analysed fine grained (clayey) sediments from three Latgale lakes - Zeili, Pauguļi and Plusons, situated in Latgale upland. Lake sediments cover Late Pleistocene glacial deposits – loam and sandy loam. Bulk mineral composition of 6 sediment samples was determined by X-ray diffraction (XRD). Sediments contained typical minerals found in surrounding glacial sediments: rock-forming minerals as quartz, plagioclase, albite, enstatite, dolomite, calcite, and clay minerals - illite, kaolinite. To identify postdepositional changes in lake sediments of Holocene age clay minerals in clay fraction (<2 mkm) should be analysed. Particularly illite, smectite mixed layered minerals - illite/smectite (I/Sm) and chlorite. Additionally, grain size distribution of studied lake sediments was analysed. Accordingly, our studied sediments are clays, silty clays and clayey silts with bimodal particle distribution, except two samples from Zeiļi and Plusons with unimodal distribution.

Published: June 2019

The research is devoted to the study of data on learners’ interactions in massive open online courses. Based on the logs of online-learning platforms, the following research was made: a comparison of the behaviour of motivated and unmotivated learners regarding of video lectures, identification of the most valuable for the successful completion of the course activities of learners, creating a model of going through time-limited assignments and identification of cheating approach based on this model. The following conclusions were made: motivated and unmotivated learners watch video lectures in different ways, motivated learners appeared to be 14 times more active, the most interesting and most viewable videos were revealed. When identifying the most valuable theoretical materials influencing the successful completion of the course, the following results were obtained: some of the videos have a strong influence on the successful completion of the final assignment. Some of the videos appeared to have weak effect, they can be interpreted as non-obligatory. Ungraded tests have a positive but moderate effect on learners’ success, while communication via discussion forum has no effect at all. In addition, a model of going through time-limited assignments was built using the average passing time of reliable learners, the approach for identifying cheating with examples is presented in the study.
COMPETENCY-BASED TRAINING IN HYDROLOGICAL EDUCATION
Authors: Timofeeva Larisa , Timofeeva Zinaida
Published: June 2019

Hydrology is an interdisciplinary science, incorporating aspects of many Earth Sciences. Key hydrological tasks such as floods prediction, quantitative and qualitative assessment of water resources and the environmental status of water bodies become increasingly important and challenging. Latest advances in scientific and technological developments require update training. The World Meteorological Organization (WMO) encourages increasing capacity of its Training Centres to address the rapidly developing demand for improved services. However, adequate education is generally not yet available. Implementation of competency-based training is needed, including active learning approaches. The paper presents international experiences and results of the use of project-based and flipped learning while teaching hydrological curriculum at Russian State Hydrometeorological University, Saint Petersburg. Some pros and cons of these approaches and difficulties of their implementation are discussed. Usually, students improve both their competence to work independently and solve problems collaboratively. Tackling near real issues and dealing with case studies get them more engaged in educational process and enhance practical outcomes. The feedback from the students and exam results have proved the efficiency of these approaches.

FUZZY MODELLING OF THE ACADEMIC STAFF ATTESTATION PROCESS
Authors: Lambeva Milena Harieva , Atanasov Valentin
Published: June 2019

A large class of real-world problems, arising in the administrative - organizational systems is connected with the attestation of the academic staff in accordance with predefined and linguistically described evaluation criteria. Such problems are solved in the circumstances of uncertainties of different types. The process of interpretation goes together with some ambiguity and inaccuracy due to the subjective interpretation of the criteria by experts. The Fuzzy Set theory provides a convenient apparatus for formalization and creation of new intelligent decision-making methods, based on analysis and processing of the expert knowledge. This paper offers a method of fuzzy modelling of the problem of scientific and pedagogical staff attestation which gives the possibility of an adequate interpretation of the attestation results. The method can be implemented programmatically and can be incorporated in the systems of education quality management.

Authors: Zhestkova Elena , Gusev Dmitriy , Kudakova Natalja , Gubanihina Elena , Klyueva Elena , Povshednaya Faina
Published: June 2019

The article is devoted to the organization of independent work of students enrolled in the direction of teacher training based on web quests. An example of an educational web quest for the 3rd year is the “Inclusive School”. One of the leading directions of development of the system of higher pedagogical education is the strengthening of the practice-oriented orientation of the study of disciplines, including the educational cycle. This concerns not only an increase in the share of active and interactive methods in teaching, an increased attention to organizing and conducting internships in educational institutions, but also a change in the approach to organizing independent work of bachelor students. Much attention is increasingly given to increasing the level of information and communication competence of future teachers (electronic libraries and educational Internet portals are the main source of educational information for modern students), it is advisable to use information and communication technologies as an organizational and substantive basis for independent work. This approach to the organization of independent work involves the development of tasks by teachers using Internet technologies, which, depending on the type of task, can be performed online or offline. Tasks for independent work can be directed to an independent search in the network with the subsequent processing of information about a specific problem; on the organization of interaction in the network; create web pages; conduct educational research, social or educational projects. The forms for presenting the results may also vary: text documents (with hyperlinks), databases of multimedia presentations, web pages, web quests. Particular attention, in our opinion, should be paid to teaching real web quests. A web quest is considered as an activity-oriented didactic model that provides for students' independent search work on the Internet. As a form of organizing independent work, a web quest has several advantages, including: increased student motivation; activation of individual or group activities; more efficiently use the understanding of the time allotted for independent work of students; the ability to not only integrate different types of assignments and forms of providing results, but also to vary the level of difficulty of the task for independent work, the duration of implementation, the number of performers.

EVALUATION OF HEARTROT CAUSED PHELLINUS PINI AND RELATED YIELD LOSS IN PINUS SYLVESTRIS STANDS
Authors: Miklašēvičs Ziedonis
Published: June 2019

Tree wounds are the starting points that may lead to heartwood discoloration and decay caused by invading micro-organisms such as heartrot caused Phellinus pini. Phellinus pini most frequently occurs on douglas–fir (Pseudotsuga menziesii), pine (Pinus sylvestris) and spruce trees (Picea abies). According to investigations made in this area, infection by Phellinus pini entries through felling scars or broken tops when Phellinus pini fruiting bodies (conks) on other trees are realising airbone spores. When spores land on a freshly wounded stem, the infection process starts. Internal decay is often difficult to detect because only Phellinus pini conks indicate its presence. In most cases the number of conks doesn’t exceed one-two pieces on the surface of inficied Pinus sylvestris stems. When wood poles for power lines are harvested in length from 10 to 16m in wood felling areas where the average height of Pinus sylvestris trees is more than 27m, the local distribution of heartrot doesn’t exceed for more than 1.5m above and below each conk, the conk is located in the middle part of the pole length, the speeed of pruning exceeds 4m/sek, the hight level of risk exists that the damaged with heart rot wood pole will be accepted as appropriate to quality requirements toward heartrot because after pruning the presence of conk would be vanished but the top and butt surfaces of pole’s won’t indicate heartrot. The evidence of heartrot will be checked only in the technological process of debarking before impregnation when Phellinus pini conk place indicates. The purpose of this study is to predict the influence of Phellinus pini on Pinus sylvestris stems and to provide operational and safety recommendations concerning the risky assessment and management of infected felling areas in harvest planning processes.

Authors: Lazov Lyubomir , Angelov Nikolay , Teirumnieks Edmunds
Published: June 2019

For a number of new laser technology processes, it is essential to plan an experimental plan for primary experimental engineering activities in terms of quality. The assessment of the critical power density to reach the melting or evaporation temperature of the surface with a suitable theoretical model is an important stage in the development of a particular manufacturing technology. With the help of numerical experiments, this report provides a method for pre-examining the influence of wavelength on the laser technological process. The calculations are performed with a specialized program, running MATLAB. A series of temperature fields were obtained at a change in power density and wavelength at laser impact for concrete types of structural steel. The temperature dependence of the optical and thermo-physical characteristics of the material is also reporded. The analysis is made for laser technology complexes working with lasers emitting in the ultraviolet, visible, near and distant infrared areas. For these wavelengths the critical power density of melting and evaporation is determined.

Published: June 2019

Studying the impact of speed on a number of laser processes such as marking, engraving, cutting, welding and others is crucial for the optimization of these technological processes. The processing speed, along with the frequency of laser pulses and their duration, also determines the time of action in the processing area and hence the absorbed quantity of electromagnetic energy. Based on numerical experiments with specialized software TEMPERATURFELD3D, the report analyzes the temperature variation in the processing area as a function of speed. The researches were analyzed for processing with two types of lasers emitting in the visible and infrared areas of the electromagnetic spectrum and two types of steels (tool and structural). From the course of the obtained temperature fields the dependence of temperature on the speed at two power densities was obtained. The obtained results help to make a preliminary assessment the speed work intervals for the processes as laser marking, laser engraving, laser cutting, laser welding and others. In this way, it is assisted in building an optimal concept for the passing of a particular technological process in function of the laser source, the material and the type of the technological operation.

Transformation of the relief of territories of development of gas mining deposits of the Taza peninsula
Authors: Bolshanik Petr Vladimirovich , Mukhamedyanov Timur Ilfatovich
Published: June 2019

The article discusses the natural conditions of the territory of the Taz peninsula in order to highlight the main natural factors in the transformation of the relief. Special attention is paid to the characteristics of permafrost and cryogenic processes and phenomena observed in this area. The characteristic of geological rocks that make up this territory is given. The influence of the hydrometeorological conditions of the Taz Peninsula is estimated. The main factors of the natural environment that determine the formation of a layer of seasonal melting are: the lithological composition and properties of soils, vegetation cover, topography, surface drainage. The main factor determining the heterogeneity of the soil temperature regime is the spatial unevenness of the snow cover thickness in this area depending on the microrelief of the region and vegetation. The influence of the anthropogenic factor on the transformation of the relief is substantiated. Three categories of violations were identified: areal (occurs during the development of fields and the construction of industrial transport facilities and other types of infrastructure); linear (when laying transport communications); and linear area (in the construction of industrial and residential facilities and a network of transport communications). The most common geomorphological processes on the territory of the Taz peninsula, activating the anthropogenic factor, are soil freezing and thermokarst caused by cryogenic processes, landslide processes and erosion, and more rarely deflation. The development of mineral deposits on the territory of the Taz Peninsula is accompanied by the construction of infrastructure for exploration and production, transportation facilities (pipelines, roads, power lines), and industrial and residential facilities. All these types of anthropogenic impact create pressure on the environment and its transformation, especially in conditions of weak stability of geosystems. Geological cryological zoning of the territory for the development of gas pipeline routes has been proposed. Priority activities in developed areas should include: recultivation of disturbed areas - restoration of damaged soil and vegetation cover, natural and geological environment, engineering and geocryological zoning, designed to develop plans for the development of the territory.

Published: June 2019

This article presents the results of a study of the nutritional status of children with acute intestinal infections (AII) occurring with hemocolitis syndrome. It was found that the nutritional status reflects the severity of the pathological process, and its dynamics allows to evaluate the effectiveness of therapy. The aim of the work was to study the changes in anthropometric indicators of nutritional status in the treatment of AII with hemocolitis syndrome in children. 50 patients with AII with hemocolitis syndrome aged from 5 months to 8 years were observed in an infectious hospital. Patients were divided by age: group 1 – breast age (n = 10), group 2 – early age (n = 27), group 3 – preschool age (n = 10), group 4 – school age (n = 3). The nutritional status of patients was studied in dynamics on the 1st and 7th day of inpatient treatment according. Analysis of research data was performed using Studentʼs t-test, U-Mann-Whitney test, Kruskal-Wallis criterion. The level and harmony of physical development of children in all groups at the time of admission to the hospital did not differ significantly. In the course of treatment, positive dynamics was noted in group 1 by the values of body mass index (BMI) (p = 0.05), Z-score BMI (p = 0.04), body weight deviation by height (in %) (p = 0.05); in group 2 – by the values of body weight by height (p = 0.05). Positive dynamics of nutrition indicators in group 1 was combined with a high frequency of diagnosis of unspecified forms of AII (60%). The negative dynamics of most indicators was observed in group 3, which was accompanied by a high frequency of diagnosis of refined (bacterial) etiological forms of AII (90%). The obtained data show that the dynamics of nutritional status of patients with AII with hemocolitis syndrome during therapy was more favorable in infants and young children and less favorable in preschool children, depended on the etiology of the disease and reflected its impact on metabolism.

Published: June 2019

We studied the morphological and functional features of the stomach and duodenum in children with chronic gastroduodenitis (CGD) associated with Helicobacter pylori infection in 3 and 6 months after successful eradication therapy. Initially we carried out examination of 155 children with CGD associated with Helicobacter pylori (HP)-infection in the acute phase of the disease. In the following we examined 100 children in 3 and 6 months after the proven eradication of HP. We found that manifestations of abdominal pain syndrome was significantly decreased (100% in the acute stage versus 7% and 5% at 3 and 6 months after eradication, p < 0.01). At the same time, almost 30% of children still had symptoms of intestinal dyspepsia (31% and 36% of children after 3 and 6 months) in the form of rumbling along the colon and changes in stool. The morphological changes in the stomach and duodenum preserved in 37% of cases: was present lymphoplasmocytic infiltration of gastric mucous and atrophy in 9%. These changes were positively correlated with the identification of CagA factor. Changes in the motor-evacuation function of the stomach were characterized by disturbances in the anthro-duodenal regulation in 25% of children and positively correlated with disorders of acid-neutralizing function.

The present study assesses the effectiveness of the relief of pain syndrome in pregnant women with dorsopathies by using an isometric kinesitherapy complex. The analyzed groups differed in the type of the performed exercise, with the first group attending a course of isometric kinesitherapy procedures (group 1) or the second group undertaking a course of therapeutic gymnastics in pregnant women with dorsopathies. The duration of each course was 7.5 hours (3 times a week for a period of 5 weeks, a total of 15 procedures), classes were conducted under the supervision by a doctor of therapeutic physical training. 170 pregnant women were examined with the average age of: Me = 31 (LQ = 26; UQ = 38) years (р > 0.05 between the groups). The low back pain (LBP) was assessed using the Oswestry questionnaire, the EuroQol 5-D questionnaire, the visual analogue scale (VAS), the verbal rating scale, the McGill short questionnaire and a medico-social form. The level of disability was assessed by using the results of the Oswestry questionnaire. Completing the questionnaires and the scales was made before the first kinesitherapy procedure (a complex of isometric exercises) and therapeutic gymnastics and completing it again after the last procedure, respectively. A prospective non-randomized controlled study was conducted in which p = 0.05 was taken as the value of statistical significance level for this study (p). The data analysis yielded statistically significant results confirming the effectiveness of the complex of isometric exercises aiming at relieving the pain in pregnant women with dorsopathies. In group 1, a decrease of the low back pain (LBP) was detected 2.47 times more often than in group 2 with p = 0.001.

During the month of November 1998, Stanley Cavell visited Caracas, Venezuela, invited by the Museum of Fine Arts and the philosophy department of Simon Bolivar University, to hold a three-day seminar on art and philosophy. During those days, Cavell presented and commented on the films Jean Dillman, by Chantal Ackerman and Sans Soleil by Chris Marker, as well as two lectures on material he was working on at that time: “The World as Things: Collecting Thoughts on Collecting,” which was published in a volume by the Guggenheim Museum with the Pompidou Center, where he also read that conference that same year (it later appeared in a final version in 2005 in Philosophy the Day After Tomorrow). The second lecture was “Trials of Praise,” where he talked about Henry James and Fred Astaire.
Stanley Cavell at Amherst College
Authors: Dumm Thomas
Published: June 2019

In February of 2000, Stanley Cavell came to Amherst College to present two public lectures as the John C. McCloy ’16 Professor of American Institutions. (I had nominated him for the lectureship the previous year, and he had been approved by a College committee and the president of the College at the time, Tom Gerety, who was himself a legal philosopher.)

It was a big deal. In the fall, the lecturer had been Ronald Dworkin. Others who had lectured through these early years of the lecture included such luminaries as Martha Nussbaum and George Kateb. (The first McCloy lecturer had been Fred Korematsu, who had unsuccessfully sued the U.S. government during World War II to end the Japanese internment program. Korematsu’s invitation had been a sort of historical reparation, since John McCloy, for whom the professorship had been named, had directed the internment camp program for FDR, famously saying, when asked about its constitutionality, “Compared to my country, the Constitution is just a piece of paper.”)

Thanking well is difficult work. And only someone who has attempted to convey thanks will know of the adversity one finds in trying to find (one’s own?) words of thanks. In an academic or we might say more broadly, bibliophilic context, the name we give to that moment of expressed and explicit (which is to say sanctioned) thanks is (the) Acknowledgments. The Cavellian resonances and overlaps of significance for this capitalized, capstone forum will stand out in high relief, even at first glance. But it is to the deep relationships between what an understanding of the Cavellian concept (or conception or even better, re-conception) of acknowledgment might (or must) betoken about the genre we call Acknowledgments that I turn to in what follows.

Portanto, nesse dossiê focamos no aspecto mais duradouro destes registros temporais e humanos: o material.
Methods for conceptual and preliminary seismic design of buildings with steel structure
Authors: Ribeiro Tiago , Sousa Ana
Published: June 2019

Throughout the last two decades, seismic design standards evolved to ever more comprehensive and detailed prescriptions, stressing out the need for design methods that deal with earthquake effects not as actions, but as a design philosophy. The Eurocode 8 adoption as national law throughout the European Union countries and informally in many parts of Africa, Asia and Latin America is the pretext for the current study. It aims to provide some guidance to the seismic design of steel structures as well as to the Eurocode 8 implementation by the designers.Some lines on the preliminary design of structural systems were written based on several real cases of structures designed taking into account the seismic action. Such a content is, usually, relevant in any design guide, given its value in enhancing the design technical and economical content. However, it is now of utter significance at the current context as an essential tool to facilitate the safety checking of several code requirements.Some of the Eurocode 8 prescriptions are then decoded, explained and justified based on the supportive bibliography. The information is subsequently ordered as a design guide, where some procedures are proposed to cope with the code interrelated prescriptions and one structural solution is proposed in order to overcome a design challenge while complying with the code.One last but not less relevant addressed issue is the fact that some Eurocode 8 prescriptions may be reviewed, in the eyes of a designer, given its practical outcome. Such issues are identified, explained and some slight code adjustments are suggested.

El objetivo del presente trabajo fue caracterizar la composición de la comunidad de peces de ocho lagunas de la Amazonía central ecuatoriana durante la época de verano del año 2011 e identificar efectos derivados de la pesca artesanal kichwa en la riqueza, abundancia, composición, biomasa, talla y captura por unidad de esfuerzo de los peces entre cuantro lagunas de pesca artesanal intensiva respecto de cuatro lagunas protegidas. Se realizó un muestreo de peces en ambos tipos de lagunas con técnicas ancestrales de pesca kichwa. Cada laguna fue objeto de pesca estandarizada en tiempos, aparejos y horario durante 1 dÃ¬a. Los peces colectados fueron identificados taxonómicamente, medidos y pesados. La completitud del muestreo se estimó con curvas de acumulación de especies y se calculó el número potencial de especies existentes con Chao 1. La riqueza de cada laguna fue considerado como la diversidad alfa. También se hicieron comparaciones de la composición y abundancia de los peces entre las lagunas bajo pesca intensiva y las protegidas mediante curvas rango-abundancia de los peces entre las lagunas bajo pesca intensiva y las protegidas mediante curvas rango-abundancia. La diversidad beta se expresó con el índice de Bray Curtis. Las variavles de riqueza, abundancia, biomasa, talla y CPUE entre ambos tipos de lagunas se compararon con estadística no paramétrica. El resultado del trabajo indicó que la riqeuza total de las lagunas presentó un mayor predominio de Caraciformes y Siluriformes, destacandose como especies más abundandes a Potamorhina latior, Psectrogaster amazonica y Triphorteus elnogatus, independientemente del nivel de pesca. Serrasalmus rhombeus aparece como especie típica de lagunas protegidas y Steindachnerica bimaculta es representativa para lagunas de pesca intensiva. Únicamente se detectó una variación estadísticamente significativa en la talla media de los peces entre lagunas de pesca intensiva respecto de las protegidas. En conclusión, las lagunas estudiadas tienen una importante riqueza de especies y la pesca local ha generado hasta el momento un cambio inicial en la dominancia de las especies bentívoras y carnívoras más abundantes así como una disminución significativa de la talle de los peces en aquellas lagunas bajo mayor pesca artesanal. En este contexto, se sugiere el desarrollo de nuevos monitoreos anuales para verificar si la tendencia inicial encontrada se mantiene y promover la regulación de los aparejos de pesca dentro de las lagunas en consenso con los pescadores kichwa para garantizar la conservación de la biodiversidad local y la mantención de la soberanía alimentaria. viewed = 1114 times

India is one of the fastest growing countries in the world, yet, it is notorious for its rigid caste system. This paper examines the history of suppression, condition of the suppressed and origin of Dalit writings. It includes the study of movement and scope of Dalit literature. It is widely believed that all Dalit literary creations have their roots in the Ambedkarite thoughts. The paper also dissects the stark realities of Dalit and their commendable attempts to upraise socially. This literature shows dramatic accounts of socialpolitical experiences of Dalit community in the caste based society of India.It traces the conditions of the Indian social factors that surround the Dalits and their interactions with Dalits and non-Dalits. It explores how Dalit community struggled for equality and liberty. Due to strong Dalit movements as well as hammering on upper caste society through Dalit literature by writers and thinkers, and also by implementation of welfare schemes by Government, a positive approach toward equality is seen in social life of Dalit community nowadays. Discrimination on the basis of caste and gender are banned by law. This is a journey of oppressed from quest for identity to social equality through their literature.
THE QUESTION OF CHANGING THE CONCEPT, ROLE AND FUNCTIONS OF STATE
Authors: Vargas-Hernández, José G.
Published: June 2019

This paper on the question of the concept, role and functions of State, attempts to critically analyze recent developments and transformations. It is assumed that all existing State models to date are in ideological crisis that challenges the concept of State.The problem is that the empirical evidence of the role and functions of the State or the State system are different from a standpoint of a range of spheres of government, which generate the multiple requirements of the regulatory activity of the State. In the discussion some questions are identified and proposals that may be useful for analyzing the transformation of the State are formulated.

Authors: Niranjan Dr. Sunil Kumar
Published: June 2019

WTO is a product of Uruguay round of negotiation of  world trade and successor organization of GATT.It has lots of agreement regarding agriculture and other parts of the trade but as the developing countries has expecting the positive result on trade of agriculture is not going to fulfill due to deterioration of terms of trade of agriculture products.therefore the true benefit of the formation of WTO is not achieved by the international community in respect of agriculture trade specially the sugar trade of India

The obligation and disciplines incorporated in the agreement on agriculture, therefore related to :

Increased market access for agricultural trade.

Reduce domestic subsidies or domestic support on agricultural trade.

Commitments to reduce export subsidies on agricultural products.

But developed nations is not fulfilling the above given agreement is also the major setback for free and fair agro trade of the international level.

In children of less than 59 months, Malaria is a public health problem, associated with an increased risk of mortality and morbidity. Thus, to improve the quality of the biological diagnosis of malaria, we made a comparative study for results of malaria test using the detection antigen HRP2 by SD bio line and calibrated thick smear. As participants, 204 patients admitted at the Bertoua regional hospital, biological diagnosis was based on the staining of the calibrated thick smear and the rapid diagnosis test SD BIOLINE Malaria Ag pf.

The results of this study showed a good performance of the TDR SD BIOLINE Malaria Ag pf, 29(14.21 %) were TDR positive versus 32(15 .68%) for calibrated thick smear. the sensitivity, specificity, positive and negative predictive values of TDR compared to the calibrated thick smear were respectively (87 .5%, 99.41%, 97.71%, 96.55%) the limitations of RDT were shown with low parasitaemia. The cases of false positives were noted in patients who took drugs without prescription. At the end of our study, we suggested continuous use of RDTs in health centres to strengthen microscopy, which has a long analysis time and to strengthen the staff’s ability in management of malaria cases.

Mathematical model of the elastoplastic shell collapse, taking into account the possible development of the process instability
Authors: Novoseltsev А.S. , Babkin A.V.
Published: June 2019

The mathematical model for the subsequent numerical study of the shaped charge liner collapse affected by external surface forces simulating an explosive load is presented. The basic liner was considered as an originally cylindrical compressible elastoplastic shell within the framework of a two-dimensional flat nonstationary problem of continuum mechanics. To ensure the rationality of the modeling and numerical calculation at the initial time the design fragment was discriminated in the liner by central beams. Deformation of the fragment being a part of the shell was taken into account by the boundary conditions of cyclic repeatability in the tangential direction. For numerical solving the well-known Wilkins Lagrangian method was used, which was refined in terms of the relations describing the mechanical behavior of an elastoplastic medium. Additionally, a self-developed grid adjustment procedure was used, excluding the appearance of highly elongated cells in the calculation. The instability of the shell deformation was initiated by harmonic surface perturbations, initially assigned on the outer or inner surfaces. The degree of instability was assessed by the deviation of the disturbed surface (or the boundary of the so-called stream-forming layer) from the cylindrical one. The used finite-difference algorithms are implemented in the form of appropriate calculation programs. A number of computational verification measures was performed proving the viability of the developed mathematical model and the possibility of its further use
