National research and educational network (NREN) is a key factor for modern research and education. The article considers the prospects and directions of the NREN development in the Russian Federation. In 2019, as a result of the merging of the departmental research and educational networks RUNNet and RASNet, a federal scale telecommunications network called the National research computer network (NRCN) was created. It should play the role of a NREN for the international cooperation projects. The concept of NRCN was approved at the Meeting of the Council of the Ministry of Science and Higher Education of the Russian Federation on information and telecommunication infrastructure, information security and supercomputer technologies. NRCN development plans include setting up the circle backbone infrastructure as well as deploying the federal network nodes in the Siberia and the Far East and providing effective interconnection to the present regional network nodes. The plan is intended to optimize network connectivity and to improve the quality of the data transmission as well as to implement Service Level Agreement (SLA) and variety network services for research and education. The implementation of the considered plans will significantly improve the reliability of the backbone and regional components of the NRCN, expand the potential of the IT infrastructure for research and education, focused on the MegaScience, highperformance and distributed computing, Big Data, Deep Learning and AI.

Проведено механико-математическое моделирование селективного водозаборного процесса в трехслойном стратифицированном водоеме, когда вода забирается из внутреннего объема промежуточного слоя водоема. Составленная математическая модель представляет контактную начально-краевую задачу теории поверхностных и внутренних гравитационных волн в идеальной несжимаемой жидкости. Водозабор из внутреннего пространства промежуточного слоя смоделирован в виде объемного стока с бесконечно малой толщиной и конечным сточным расходом. В результате решения поставленной начально-краевой задачи получена система расчетных формул, которая с привлечением компьютерных средств позволяет выбирать диаметр водозаборной трубы и расход через нее, вычислять отметку глу- бинного расположения конца водозаборной трубы. Выбор этих параметров обеспе- чивает селективный водозабор исключительно из промежуточного слоя, где вода чище и холоднее, чем в других слоях водоема.

The purpose of this work is to carry out mathematical modelling of selective water intake process in a three-layer stratified reservoir, when the water is taken from the interior volume of the intermediate layer of the reservoir. In the methodology for solving the problem, the water intake from the interior volume of the intermediate layer is modelled as a finite flow rate drain of fluid trough an infinitely thin layer. The contact initial-boundary value problem of the theory of surface and internal gravitational waves in an ideal incompressible fluid is used as a mathematical model of the water intake process. As a result we obtain a system of calculation formulas for estimation of the diameter of water intake pipe and the flow rate through it. The depth mark of the end of the water intake pipe was calculated. Originality/value: 1. The boundary value problem simulating a selective water intake process from the internal volume of the intermediate layer of a three-layer stratified reservoir was formulated and solved. 2. On the basis of the obtained set of formulas, computer experiments were performed and thus the regularities of the influence of the above external input parameters on the process were established. 3. The choice of these parameters provides selective intake exclusively from the intermediate layer, where the water is cleaner than in the lower layer and colder in summer than in the upper layer.

The paper discusses approaches to the numerical integration of the second-kind Manakov equation system. Emphasis is placed on the transition from writing equations in dimensional quantities to equations in dimensionless units. A combined explicit/implicit finite-difference integration scheme based on the implicit CrankNicolson finite-difference scheme is proposed and substantiated, which allows integrating a nonlinear system of equations with a choice of nonlinear term at the previous integration step. An algorithm for leveling the disadvantage associated with the definition of the nonlinear term from the previous integration step is proposed. The approach of automatic selection of the integration step, which reduces the total number of integration steps while maintaining the required accuracy of the approximate solution, is substantiated. Examples of the calculation results for some values of the disturbance propagation are given. The limitations imposed by the computing scheme on the length of the integrable fiber section are described, and approaches, that eliminate these limitations without the need to increase arrays dimensions, are proposed. Requirements for initial boundary conditions are discussed.

Предложена разработка метода приближенного решения системы уравнения Манакова как одного из частных случаев системы уравнений Шрёдингера, связанного с моделированием оптических линий связи на основе многомодовых волокон. Решение ищется методами численного интегрирования. Показано, что численное интегрирование может быть осуществлено с использованием комбинированной явно-неявной схемы численного интегрирования на основе схемы КранкаНиколсон с записью нелинейного слагаемого в конечно-разностной форме, взятого с предыдущего шага интегрирования. Использован алгоритм автоматического выбора шага интегрирования, реализован итерационный алгоритм уточнения решения на каждом шаге, предложен алгоритм, позволяющий производить расчет параметров на протяженных участках. Нахождение приближенного решения системы уравнения Манакова может быть осуществлено с использованием комбинированной явно-неявной схемы КранкаНиколсон, а запись нелинейного слагаемого в конечно-разностной форме, взятого с предыдущего шага интегрирования, дает неплохой результат. Алгоритм автоматического выбора шага интегрирования обеспечивает лучшую сходимость результатов интегрирования на большом расстоянии и снижение необходимого количества шагов интегрирования. Алгоритм уточнения решения на каждом шаге позволяет нивелировать недостаток метода явной записи неявного слагаемого и интегрировать с большим шагом. Алгоритм расчета параметров распространения возмущения со сдвигом фрейма позволяет сделать вывод о целесообразности развития этого алгоритма.

Der Aufbau von Vertrauen wird in Theorie und Praxis Sozialer Arbeit als Voraussetzung für Hilfe diskutiert. Wenn eine sozialpädagogische Familienbegleitung (SPF) als Massnahme im zivilrechtlichen Kindesschutzbereich angeordnet ist, geht ihr Hilfeauftrag mit einem Schutzauftrag einher, manchmal auch gegen den Willen der Betroffenen. Es ist anzunehmen, dass der Aufbau einer vertrauensvollen Zusammenarbeit erschwert ist. Der Beitrag beleuchtet auf der Grundlage einer rekonstruktiven Studie den Aufbau von Vertrauen im Ausgangspunkt solcher Familienbegleitungen und fokussiert auf vertrauensrelevante Ausgangsbedingungen.
„Vom rechten Rand wieder eher ein stückweit in die Mitte" – Ausstiegs- und Distanzierungsarbeit als institutionelle De- und Resozialisierungsinstanz?
Authors: Hohnstein Sally , Greuel Frank , Figlestahler Carmen
Published: October 2021

Im Beitrag werden Hinwendungen zum Rechtsextremismus aus theoretischer Perspektive als Prozesse (politischer) Sozialisation begriffen, in denen junge Menschen – entgegen den Erwartungen demokratischer Gesellschaften – extremistische Weltsichten und Zugehörigkeiten entwickeln und konsolidieren. Ausgehend von der Überlegung, dass eine Sozialisation in den Rechtsextremismus grundsätzlich ein offener und damit auch umkehrbarer Prozess ist, wird die Abkehr vom Rechtsextremismus ebenfalls als sozialisatorischer Prozess begriffen. Wir adaptieren die Konzepte der Desozialisierung und Resozialisierung, um die Vorgehensweisen und Zielsetzungen von professionellen Angeboten der Ausstiegs- und Distanzierungsarbeit zu systematisieren. Auf Basis zweier empirisch-qualitativer Studien zu Praxiserfahrungen von Angeboten der Ausstiegs- und Distanzierungsarbeit zeichnen wir nach, wie Prozesse der Desozialisierung und Resozialisierung auf zentralen Zielebenen der Arbeit angestoßen werden und ineinandergreifen sollen. Betrachtet wird dabei auch, welche Zielvorstellungen in der Arbeit mit den Adressat:innen existieren und den normativen Korridor des Erwünschten darstellen.

The principles of glaucoma diagnostics are based on the triad of symptoms -the excess of IOP over the tolerant level, changes in the visual field, primarily in the Bjerrum zone, and also on glaucomatous excavation of the optic nerve head. It should be recognized that the IOP level is the only proven risk factor for the progression of glaucomatous optic nerve atrophy and, at the same time, the only factor that we can influence. That is why the determination of IOP is of great importance in diagnosis and is the basis for evaluating the effectiveness of glaucoma treatment.Keywords: IOP (intraocular pressure), tonometry, glaucoma, primary open-angle glaucoma, glaucomatous optic neuropathy, tonometer, pneumotonometer

Authors: Asim Muhammad
Published: October 2021

Rutting (permanent deformation) is one of the most common and serious kinds of damage to flexible pavement, particularly in countries with high summer temperatures. Rutting also occurs when there is a lot of traffic and the use of poor materials. Pavement engineering is greatly influenced by the use of materials such as asphalt and cement in modern times. To study the effect of load, high temperature, and materials properties on rutting damage of flexible pavement this paper is the best approach to all these concerned issues related to rutting. Abaqus ver.6.12.1 has been used to simulate flexible pavement under different loading and thermal conditions. Three models have been developed in this paper, the first model simulated against traffic loading only, the second model shows combined traffic and thermal loading while the third model related with the change of materials property in terms of Young’s modulus (E).

Published: October 2021

The lack of relevant Teacher Education Training Programme (TETP) specifically for economics teachers in Technical Vocational Education and Training (TVET) colleges globally, including South Africa has posed many challenges for teachers. This study reports on the pedagogical challenges of Economics teachers with Postgraduate Certificate (PGCE): Further Education and Training (FET) phase teaching N-level 4 economics in Technical and Vocational Education and Training colleges. The study investigated the pedagogical challenges experienced by economics teachers during the teaching and learning of N-Level 4 economics in one college at Motheo Technical and Vocational Education and Training College. The seven categories of teacher knowledge by Shulman's (1987), underpinned this study. In addition, the pedagogical challenges of Business Studies in secondary schools by Kimotho (2016) serve as a lens to understand the economics teachers’ challenges in a Technical, Vocational Education, and Training college. This qualitative research approach used an exploratory case study research design, and selected two economics teachers purposefully and their students who were observed in two different classrooms and later interviewed individually. The findings revealed that the economics teachers displayed five pedagogical challenges associated with content knowledge (CK), curriculum knowledge, pedagogical content knowledge (PCK), knowledge of students, and the interaction with students. Based on the study’s limitation, there is a need to identify the educational implications on economics teachers’ pedagogical challenges when teaching economics to N-Level 4 students.

Translating a pandemic: A corpus study of COVID-19 multi-word terminology in EU press releases
Authors: Tomaszewska Aleksandra , Zawadzka-Paluektau Natalia
Published: October 2021

The study employs a parallel English-Polish corpus to investigate how COVID-19 multi-word terms are handled in translations of EU press releases. Translation techniques are examined at four levels of analysis: (1) term variation, (2) institutionalization, (3) domestication/foreignization, and (4) degree of transfer of information. The results are discussed in regard to the characteristics of COVID-19 terminology and its, often neological, instability, which manifests itself in high levels of terminological variation, inconsistent use of recommended institutional equivalents, and varied degrees of information transfer between SL and TL. The findings are also reviewed in light of the nature of press releases which, as an essential link in the transmission of knowledge from EU institutions to citizens, prompt the use of domesticating techniques.
Conference interpreting on the privatemarket: Employment and assignment-related variables
Authors: Adams Heather , Bovy David
Published: October 2021

The benchmark for the study of conference interpreting tends to be the institutional market, in which employment conditions are secure and communicative situations, context and terminology will tend to recur. By contrast, conference interpreters working in the private sector face a range of ever-changing circumstances, negotiating each assignment not only in terms of remuneration but also in terms of all aspects relating to working conditions, thus requiring an increased capacity to adapt on many levels.

This article presents findings from a pilot study that aims to showcase what interpreters working in the private market actually do before their interpreting assignment, over and above the preparation work that all interpreters put in. After a brief contextualization based on both academic and professional literature, this article presents the responses to two questions posed in our study regarding additional tasks carried out before assignments. Our conclusions are relevant to practitioners, trainees and trainers, as they shed light on current professional practice.

An unprecedented dinuclear Ni(II) complex [{Ni2(L)(HL)(μ-OAc)(H2O)}2]·3CH3CH2OH is successfully synthesized by the complexation of an asymmetric salamo-based ligand (H2L) and Ni(II) acetate tetrahydrate and characterized by elemental analyses, UV-Vis and IR spectra, and X-ray crystallography analyses. Surprisingly, in the asymmetric unit of the Ni(II) complex, a fully deprotonated ligand (L)2– unit and a partially deprotonated ligand (HL)– unit wrapps two Ni(II) atoms, with the μ-OAc– anion bridging two adjacent Ni(II) atoms. The two Ni(II) atoms possess different coordination environments and twisted octahedral geometries. The hexacoordinated Ni(II) atom (Ni1) is located in the N2O4 donor cavity, but another hexacoordinated Ni(II) atom (Ni2) is located in a NO5 donor coordination environment. Meanwhile, a1D chain structure is formed by two N—O⋯π interactions. Hirshfeld surfaces and fluorescent properties are investigated.

Каркасные титаносиликаты семейства гетерофиллосиликатов с трехслойными модулями HOH обладают микропористым строением и характеризуются наличием систем широких пересекающихся или параллельных каналов. С использованием программы ToposPro выполнен теоретический анализ возможных путей миграции различных катионов. Установлено, что в гетерофиллосиликатах со структурными типами астрофиллита-1A/-2M и вебленита возможен одномерный характер проводимости ионов щелочных металлов (Na+, K+, Rb+, Cs+), серебра (Ag+) и свинца (Pb2+) по системе широких параллельных каналов в направлении [100]. Замена крупных щелочных катионов на литий существенным образом меняет характер ионной проводимости. Благодаря меньшему радиусу катионы Li+ могут проходить через окно между каналами, формируя двумерный проводящий слой, параллельный (001).

Published: October 2021

A new zinc(II) complex of 2-(((2-((2-hydroxyethyl)amino)ethyl)imino)methyl)phenol (L), [Zn(Lz)Br2] (1), is prepared and identified by elemental analysis, FTIR and 1H NMR spectroscopy, and single crystal X-ray diffraction. The X-ray structure analysis of 1 reveals a tetrahedrally coordinated zinc(II) complex containing the NO-donor amino alcoholic Schiff base ligand and two bromo ligands. After complexation, the ligand (L) converts to its zwitterionc form (Lz) of phenol → phenolate; amine → ammonium. In this structure, hydrogen bonds between amine and alcohol units form different types of hydrogen bond motifs, including R21(7), R22(7), R22(10), R44(24), R44(30), R66(38), and R66(44). In addition to the hydrogen bonds in this crystal network, there are π—π stacking interactions between the phenyl ring and the imine group. The ability of the ligand and its isostructural complexes [Zn(Lz)Br2] (1), [Zn(Lz)Cl2] (2), and [Zn(Lz)I2] (3) to interact with ten selected biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS, Top II, and B-DNA) is investigated by docking studies. The results show that in some cases, the studied compound can interact with proteins and DNA better than doxorubicin. The charge distribution pattern of the ligand and complex 1 is studied by the NBO analysis.

In this study 422 subjects were conducted using Lottery method to select them. The independent variables were socio-demo­graphics charctestics and obstetrics’ health related factors with outcome variable of post­natal care service utilization. Binary and multi­variable logistic regressions analysis were computed to evaluate the factors associated with postnatal care services utilization.
Results: In this study a total of 422 women were interviewed with a response rate of 100%. Out of the total respondents, 178 (42.2%) uti­lized postnatal care service after delivery within six weeks of their last birth. Educational level of mothers (OR= 1.96; 95% CI= 1.06 to 3.62; p= 0.050) maternal knowledge on postpartum danger sign & symptoms (OR= 1.78; 95% CI= 1.16 to 2.72; p= 0.010) pregnancy desire (OR= 1.89; 95% CI= 1.67 to 3.35; p= 0.050) ANC visit (OR= 2.80; 95% CI= 1.32 to 5.97; p= 0.010) and place of deliver (OR= 2.09; 95% CI= 1.30 to 3.34; p= 0.010) had showed statistical signi­ficant association with postnatal care utilization.
Conclusion: More than half of respondents in Goba woreda were not utilized postnatal care service. Maternal educational status, maternal knowledge on postnatal danger signs and symptom, pregnancy desire for youngest child, ANC attendance and place of delivery found to be independent predictors for PNC service utili­zation.
Oosterweel – from an underground and even underwater road infrastructure plan to an urban transformation project
Authors: Hellemans Luc
Published: October 2021

For the coming ten years, the heart of Europe will turn into a gigantic construction site for works on one of the largest hubs of the continent: Antwerp. The Oosterweel Link is the project whereby the motorway ring around Antwerp is undergoing a metamorphosis to reinvigorate traffic flow and add living space to the City. The project had come to a standstill for several years as a result of protests by assertive citizens, but was given a second lease of life following a large-scale participation project.

To ensure its successful completion, unparalleled efforts are being made in the field and in the area of digitization. It is therefore with good reason that in Belgium the project is referred to as “the construction site of the century”.

The purpose of this study is to investigate the impact of climate change on the thermal and structural response of concrete box girders. An advanced finite element platform was used to model a concrete box girder and analyze the additional thermal stresses that result from climate change. Meteorological data for future climate scenarios in Toronto, Canada was used as input in a thermal model to simulate the temperature distribution within the bridge deck. The temperature distribution was then used as input in a structural model of the bridge, to determine the resulting thermal stresses. The results show increases in tensile and compressive stresses as well as increased bridge movements. This study highlights the importance of explicitly considering climate change to achieve more robust bridge codes, particularly when it comes to thermal effects.
Lessons learned from using a donor skeleton in a 3 storey office building
Authors: Terwel Karel , Moons Matthij , Korthagen Paul
Published: October 2021

During the last decade a lot of attention has been paid to sustainability of structures. Reuse of existing buildings, limiting environmental impact and reuse of elements were applied in practice. In general, reuse of elements, with for instance the use of a donor skeleton, was applied on a very limited scale, as this reuse often comes at a price. In 2018 there was an opportunity to apply a donor skeleton on a larger scale in an office building of 6200 m². This paper will describe the process of design and construction of this special project, and will derive lessons learned in order to increase application of upscaling of building elements in future projects.
Modeling of the behaviour of concrete elements containing a self- healing agent
Authors: Zhelyazov Todor , Ivanov Radan
Published: October 2021

This contribution focuses on the numerical modelling and simulation of the mechanical behaviour of structural elements containing a self-healing agent. Specifically, the finite element modelling of the mechanical response of plain concrete structural element, containing a healing agent and subject to various loading conditions is discussed. A customized numerical procedure designed to implement the Damage Mechanics-based constitutive relation for concrete into a general-purpose finite element code is developed. The procedure comprises algorithms for evaluation of the volume of newly-formed cracks, the recovery of stiffness of the structural element due to crack closure, the initiation of healing and its effect on the overall response of the structural element. The procedure is demonstrated by simulations of a concrete cylinder subjected to compression and torsion.
Effective re-use of existing structures towards the sustainable society at East Japan Railway Company
Authors: Kino Junichi
Published: October 2021

Since we have laid enough railway network, there are only a few new construction projects of railway structures, and we mainly do improvement projects. In railway improvement projects, we generally dismantle old structures and construct new ones. However, in order to reduce CO2 emissions as much as possible, it is necessary to re-use existing structures the utmost. East Japan Railway Company has been carrying out many railway improvement projects, and plans to re-use the existing structures as much as possible. We have devised a construction method that re-uses the slabs and beams of the existing reinforced concrete rigid frame viaducts and remake only the columns, and have used this method in several projects. We have been able to reduce a large amount of CO2 emissions by this method.
Steel: friend or foe in the face of the climate emergency?
Authors: Swann Walter , Hanus Francois , Vasart Olivier , Knight Alan
Published: October 2021

Steel is the most recycled material in the world and a key contributor to the circular economy, but todays primary steelmaking methods result in high embodied carbon. In the face of the climate emergency, designers have been tasked with driving down the upfront emissions of the built environment. Naturally the embodied carbon characteristics of all materials have been put under the microscope and those with high impacts are being demonised, primary steel is one of those. So how does a designer balance the immediate needs of the climate emergency with the future needs of society? When confronted with a material like steel with practically perfect circularity characteristics but high embodied impacts how do designers balance the needs of today with those of tomorrow? What if steel could be made with zero carbon emissions? Coupled with its high potential for re-use and its high recycling rates is steel a friend and ally in the face of the climate emergency rather than a foe?
Investigation of seismic response of rocking column with a novel mechanical connection device
Authors: Zhong Xueqi , Bao Zehua , Li Jianzhong
Published: October 2021

The rocking column is a kind of excellent seismic-resistant and resilient structure. However, during the rocking process, local pressure on the rocking interface may result in spalling and crushing of concrete at the toe. In order to reduce the local damage of the rocking interface, as well as accelerate the connection between prefabricated column and footing, a kind of mechanical connection device (MCD) was proposed in this research. The MCD is used at the bottom of column and ofters rapid connection of the column to the footing. The recentering force of MCD column is provided by PT strands and axial force of superstructure, and the energy dissipation is provided by U-shaped dissipaters. A simplified analytical method based on interface section analysis is proposed to study the hysteretic behavior of column with MCD. The results suggest that the MCD column has stable hysteretic behavior and can achieve small residual drift after earthquakes by appropriate design.

Authors: Soudijn Maarten , van Rossum Sebastiaan , de Boer Ane
Published: October 2021

In this paper we present weight measurements of urban heavy traffic comparing two different Weigh In Motion (WIM) systems. One is a WIM-ROAD system using Lineas quartz pressure sensors in the road surface. The other is a WIM-BRIDGE system using optical fibre-based strain sensors which are applied under the bridge to the bottom fibre of a single span of the bridge deck. We have designed our tests to determine which system is most suited to Amsterdam. We put special focus on the accuracy that each system can achieve and have set up an extensive calibration program to determine this. Our ultimate goal is to draw up a realistic traffic load model for Amsterdam. This model would lead to a recommendation that can be used to re- examine the structural safety of existing historic bridges and quay walls, in addition to the current traffic load recommendations.
Condition assessment of several bridges in Sofia based on visual inspection and as-built drawings
Authors: Jiponov Alexander , Georgiev Lazar
Published: October 2021

Significant number of bridges in Sofia municipality are in halfway of their exploitation period – they are between 30÷60 years old. At the same time, there is a lack of common methodology for condition assessment of existing bridges (road, railway, pedestrian). Another issue is that there is no Bridge Management Data System, where the information from visual inspections, condition assessments and as-built drawings could be uploaded and used for further operations like regular maintenance activities, prioritization of repair works, planning budget and costs of the relevant authorities. Different structural types of bridge structures in Sofia are described in the paper. The advantages and disadvantages of the considered bridge types with respect to reliability and maintenance are analysed. Several bridges of different types are chosen in order to evaluate their condition based on visual inspection. Possibilities and advantages for implementation of condition assessment rating system based on numerical estimation are discussed.

Published: October 2021

Vehicle tracking based on computer vision is an important part of traffic load monitoring. The stable and reliable vehicle detection is the primary task of vehicle tracking. The widely used 2-D detection works accurately in simple situation but faces obstacles in dealing with multi-vehicle overlap. Therefore, this paper proposes a 3-D detection method of vehicles based on the stereo vision, which can position accurately the vehicles partly covered in the image to keep a continuous vehicle tracking. This method builds spatial relations between observed objects such as wheels and the feature points on the vehicle. With spatial relations determined, when the observed objects of the vehicle are partly covered by other objects, their positions can be inferred accurately from the visible feature points of the vehicle. Experiments were taken to verify the effectiveness of the proposed method.

New developments in civil engineering in the area of innovative high-performance materials and sophisticated geometrical designs generate the need for advanced measurement and monitoring systems. Based on years of utilizing digital image correlation (DIC) in a diverse field of applications, the advantages and disadvantages of DIC measurements are highlighted, by means of a selection of various experimental tests conducted by the authors. Recommendations for a general methodology for the utilization of DIC systems are presented. For this purpose, the beneficial advantages in the case of a variety of different chosen test setups, as well as the originated evaluation data, are shown. Such a type of non invasive optical measurement system enables the user to gather data even in challenging conditions, where a brittle failure of the specimen has to be expected and conventional measurement equipment, like LVDTs or displacement transducers, reach their limit. In addition, a simplified model for a 3D measurement setup calculation is presented.
