Published: March 2021

To increase the competitiveness of domestic universities, the "5-100 Project" is being implemented, in which from 2013 to 2020 21 universities that have been selected based on the results of "Road maps", which must necessarily reflect international cooperation, as well as plans for the development of educational programs, take part. This year, it is planned to summarize the results of the program. The interpretation of results can be heterogeneous, since it is difficult to select parameters for comparison when evaluating complex multi -parameter objects. The clustering allows you to group similar objects, while the task of the researcher is to interpret the results. It is always easier to compare objects with similar parameters. As a result, two groups were obtained. This paper analyzes the problem of evaluating the effectiveness of Universities in various parameters and their totality. Clusterization was performed using the hierarchy method in the R program. This paper examines 11 universities from the list of "5-100", information about the activities of which is most fully presented on the Internet. Built according to data provided in the University self-study reports. The analysis was carried out separately for each of the sections in order to determine the most significant parameters for the University (educational, research, international, financial and economic activities, infrastructure and training of disabled people and persons with disabilities), as well as for a set of characteristics.

ABSTRACT Planicapritermes Emerson, 1949 is a South American termite genus with two nominal species: Planicapritermes planiceps (Emerson, 1925) and Planicapritermes longilabrum Constantino, 1998. The soldiers of this genus are characterized by strongly asymmetrical mandibles. Planicapritermes planiceps was described from soldiers and workers, and P. longilabrum only from soldiers. Here we describe and illustrate workers of P. longilabrum based on specimens collected in Rondônia state, Brazil. We also present a comparison between workers and soldiers of P. planiceps and P. longilabrum, and describe the nest of P. planiceps.
Birds associated with treefall gaps in a lowland forest in southwestern Brazilian Amazonia
Authors: LIMA Jônatas , GUILHERME Edson
Published: March 2021

ABSTRACT Natural communities are dynamic systems in time and space. The spatial distribution of plants and animals tends to coincide with the availability of resources needed for the survival and reproduction of each species. Natural treefall gaps offer a number of resources that influence the distribution of birds within the forest. We compared the understory bird assemblages of natural treefall gaps (15 sampling points) with those found in the adjacent forest (15 points) in the Humaitá Forest Reserve in southwestern Brazilian Amazonia. We used mist-nets to sample birds and obtained 700 captures of 105 species. Species richness, number of individuals, and species composition were all similar between gaps and forest, although six species presented some degree of association with the gaps, and nine with the forest. Nectarivores preferred gaps significantly over forest, whereas insectivores and frugivores were distributed equally between gaps and forest. Vegetation height and density differed between gaps and forest, and influenced the distribution of bird species in the two environments. Fruit availability was positively correlated with frugivore abundance in gaps. Overall, 33.3% of the birds associated with the treefall gaps are from lower forest canopy, while the others are understory species. We showed that the use of natural gaps by birds in a fragmented landscape of the Amazon forest contributes to the environmental heterogeneity and succession dynamics following natural events of habitat disturbance.

ABSTRACT One possible alternative to chemotherapeutic agents in the treatment and prevention of diseases in fish farms is the use of Piper aduncum essential oil. However, ecotoxicological data are required to ensure its proper use and to prevent adverse effects on non-target organisms. These data are relevant since this essential oil is described as having insecticidal, molluscicidal and cytotoxic activitiy that may be associated with its chemical composition. Thus, the aim of this study was to evaluate the ecotoxicity of P. aduncum essential oil to five test organisms using the species sensitivity distribution (SSD) statistical approach. The chemical composition of the essential oil was characterized by means of gas chromatography coupled to mass spectrometry (GC-MS) and gas chromatography-flame ionization detection (GC-FID) for identification and quantitation purposes, respectively. The main component (75.5%) of the essential oil was dillapiole. The hazardous concentration for 5% of biological species (HC5) was calculated to determine the 95% protection level, resulting in a value of 0.47 mg L-1 (with a confidence interval of 0.028 - 1.19 mg L-1. ). A concentration range related to the level of protection for aquatic communities (the predicted no-effect concentration, PNEC) was determined through the application of safety factors to the HC5 value. The ecotoxicity parameters showed that P. aduncum essential oil can be used safely in water bodies at a concentration equal to or below 0.09 mg L-1.

RESUMO Este artigo, de natureza teórica, reflete sobre como a aproximação crítica com as tecnologias e com a cultura hacker no espaço escolar pode colaborar para avanços no ensino das artes. O texto se subdivide em três partes que abordam: noções de tecnologia na educação e suas implicações para as práticas de ensino; cultura hacker e condutas mediadoras de professoras/es em sala de aula; implicações das discussões anteriores para as artes contemporâneas no contexto escolar. Resulta dessa reflexão: em arte, apoiando-nos na história, só a feitura e a fruição são capazes de instaurar processos de construção e ampliação do conhecimento estético; quem cria deve ser visto e incentivado como um agente crítico dos meios, das técnicas, das tecnologias e dos temas com que opera sua criação; a criação, em arte, deve primeiro servir para que a pessoa que cria possa questionar a si, suas relações e seus posicionamentos no mundo, antes que possa propor algo dessa natureza ao fruidor.

Control flow graphs optimization in intermediate representations of the functional dataflow parallel programming language
Authors:   Siberian Federal University, Krasnoyarsk, Russian Federation, Vasilev Vladimir , Legalov Alexander ,   Higher School of Economics, National Research University, Moscow, Russian Federation
Published: March 2021

Functional dataflow programming languages are intended for the development of architecture-independent parallel programs and support the control of computations based on data availability. Due to the fact that at present parallel computing systems are very widespread, and their programming in imperative languages is associated with portability problems, the development of architecturally independent parallel programming tools is an urgent task. When such a program is translated, intermediate representations are formed as the information graph and the corresponding control graph. During program execution, data readiness signals are transmitted along the arcs of the control graph. An explicit selection of the control graph allows us not only to change the computational control strategies and ensure the adaptation of the program to the architecture features, but also to apply specific methods for optimizing control dependencies. The paper proposes transformation methods that provide optimization of the control graph. When generating a control graph from an informational one, redundant arcs are introduced into it, the removal of which does not affect the result of the program, but leads to its more efficient execution. It is shown that in dataflow programs, in addition to control dependencies inherent in other programming languages, additional ones associated with the implementation features of deferred or conditional computations described by delayed lists arise. A formal description of redundant dependencies of various types is given, as well as an effective algorithm for their identification. The developed approach can be applied to such dataflow programming languages as PIFAGOR and Smile.

Authors:   Platov South-Russian State Polytechnic University (NPI), Denisov Petr , Balaban Anna ,   Platov South-Russian State Polytechnic University (NPI)
Published: March 2021

The article proposes the modification of a technique for assessing the magnetization of permanent magnets from the known field pattern. The identification method is based on solving an ill-conditioned system of linear algebraic equations by the Tikhonov regularization method. The method of boundary integral equations based on scalar potentials is used to compile the matrix of coefficients. The article presents the algorithm that uses parallel computations when performing the most time-consuming operations to reduce the time for solving the inverse problem. In order to check the proposed method, a program was developed that allows to simulate the measurement process: to calculate the direct problem and find the magnetic induction at the points of the air gap, then introduce the error into the "measurement results" and solve the inverse problem. The results of nu-merical experiments that allow us to evaluate the advantages of parallel implementation using the capabilities of modern multi-core processors are presented.

Published: March 2021

The paper proposes a new iterative method for determining the parameters of an induction motor. The method is based on the measured values of no-load current and active resistance of the stator winding. The calculated parameters are used to build the mechanical characteristics of the engine. To assess its accuracy, a comparative analysis with a pie chart was carried out. In the practical part of the work, on the basis of the experimental stand, measurements were made of the magnitude of the electromagnetic moment of the investigated asynchronous motor AIR71A4 at different values of the rotation frequency on the stable part of the mechanical characteristic. In a comparative analysis of the calculated and experimental data, it was found that the proposed method has sufficient accuracy in calculating the primary parameters of the engine. This provides a basis for the practical use of the proposed calculation method in engineering practice

The problems of applying the achievement of general technical diagnostics for the recognition and assessment of the technical state of the stator winding in the process of performing functional processes by an asynchronous motor are considered. It is proposed to use the informative parameters of vibration acceleration obtained from full-scale experiments carried out in idle and load modes of an asynchronous motor for diagnosing an intertuеrn short circuit that often occurs in the stator winding. It is shown that for recognizing a malfunction of the stator winding of an induction motor, mathematical methods of technical diagnostics are effective, in particular, the method of potential functions and the method of diagnostics based on the angular distance in the feature space. The sequence of methods, rapid assessment of the technical condition of the stator winding and the determination of the interturn short circuit at the initial stages of its occurrence during the operation of the induction motor is given.

This article considers the development of digital twins (DT) for the mechatronic facilities of the coiling machine group in a wide-strip hot rolling mill. The analysis of Russian and foreign sources confirmed that a lot of attention is paid to the economy digitalization. All of the leading metal plant equipment and electrical engineering system manufacturers are working on creating DTs. The analysis of the literature showed that the authors lack a uniform understanding of the conceptual directions in the creation of DTs and there are many definitions of this term. Therefore, the first part of the article deals with the analysis of the digital twin concepts according to their application at industrial companies. The authors substantiate the feasibility of the DT de-velopment for the electromechanical and mechatronic systems of the most complex metal production components, i.e., rolling mills. This initiative development is relevant due to the reconstruction of the 2500 wide-strip hot rolling mill at Magnitogorsk Iron and Steel Works PJSC (MMK PJSC) that involves the installation of unique equipment. Due to this, the development of DTs to implement the virtual commissioning of the equipment becomes a priority. The virtual adjustment of automation and process control systems is also required. This problem can be solved through the example of three coiling machines, each of which has electric and hydraulic auxiliary equipment. These coiling machines are used for rolling the heavy hot-rolled bar and they feature a unique design. Therefore, the development of DTs for mechatronic facilities is a novel scientific problem. The authors propose the methods for the development of DTs used in the virtual commissioning of process control systems. They present the structure of the coiling section automation system and the structure of the DT imple-mented on the basis of programmable logic controllers (PLC). The authors provide the specifications for the Siemens PLCs installed at each of the coiling machines and the coiling machine master controller. To develop the control systems for electric and hydraulic drives, it is recommended to use the Matlab Simulink software package. The authors provide temporal dependencies obtained using DTs and other similar oscillograph charts produced during the operation of the coiling machine that can help model the operation of the mechanisms in question. The results of their comparison show that the processes correspond to each other. Thus, the use of the developed DT to adjust the electrotechnical systems of rolling mills is reasoned. The accepted concept of making digital twins for the electrotechnical systems of rolling mill components is relevant and technically feasible

Published: March 2021

The 18 May 2020 Ms 5.0 Qiaojia earthquake occurred in Qiaojia County, Yunnan Province, ∼25  km away from the 3 August 2014 Ms 6.5 Ludian earthquake. This earthquake was well recorded by dense local seismic stations of the Qiaojia array constructed near the Xiaojiang fault zone. The focal mechanism of the mainshock exhibited strike-slip motion with a centroid depth of 8 km. We determined the seismogenic fault of the Qiaojia earthquake using aftershock relocation with local dense seismic arrays. The mainshock is located on a previously unmapped fault. Aftershocks clearly delineated east–west rupture plane, which was not revealed by the regional seismic network due to relatively sparse stations. The length and width of the aftershock zone are ∼5  km and 3 km, respectively. The focal mechanisms of 70 aftershocks with magnitudes ML≥1.0 showed similar focal mechanism with the mainshock. The stress field inverted from focal mechanisms of the aftershocks is consistent with the tectonic stress field. The coseismic and postseismic static coulomb stress changes show that the Ludian earthquake has a negative impact on the Qiaojia earthquake with a value of −0.01  MPa, implying that the Qiaojia earthquake was unlikely statically triggered by the Ludian earthquake. The Qiaojia earthquake sequence was characterized by low b-value and low-decay rate in the aftershock area, indicating high-seismic risk in this region. The dense seismic observation allows us to study the moderate earthquake in detail and provides us with valuable information of near-fault seismicity to analyze earthquake hazard and the potential of large earthquakes in the future.
An Assessment of Earthquake Scaling Relationships for Crustal Earthquakes in Indonesia
Authors: Gunawan Endra
Published: March 2021

To estimate the hazard posed by active faults, estimates of the maximum magnitude earthquake that could occur on the fault are needed. I compare previously published scaling relationships between earthquake magnitude and rupture length with data from recent earthquakes in Indonesia. I compile a total amount of 13 literatures on investigating coseismic deformation in Indonesia, which then divided into strike-slip and dip-slip earthquake cases. I demonstrate that a different scaling relationship generates different misfit compared to data. For a practical practice of making seismic hazard model in Indonesia, this research shows the suggested reference for a scaling relationship of strike-slip and dip-slip faulting regime. On a practical approach in constructing a logic tree for seismic hazard model, using different weighting between each published earthquake scaling relationship is recommended.

Application of synthetic compounds seed dressing enhancing yield and yield components of crops but it is becoming very expensive for resource poor farmers beside this; these also have a negative effect on the natural environment. Thus, the current field and laboratory experiment was conducted during the 2018 main cropping season for testing the potential of locally available plant extracts; garlic (Allium sativum), ginger (Zingiber officinale), neem seed (Azadracta indica), varnonia leaf (Vernonia amygdalina) and crouton leaf (Crouton macrostachya) as seed priming materials on malt barley. Three levels of each priming material (5%, 10% and 15 % concentration) were prepared and full sized malt barley seeds were soaked for 12hrs in these priming materials. Seed dressing chemical (Dynamic 400 FS), distilled water soaked seeds, and dry seeds were used as a control for the field experiment. Primed seeds with all concentrations of botanicals, including distilled water and dynamic dressing chemical had a significant enhancing effect on agronomic parameters of malt barley under both laboratory and field conditions except for the effect of ginger extract priming which negatively affected the agronomic parameters as compared to dry planted (untreated) seeds. However, there was clear variation among botanical extracts and this is depending on their concentration and types of used botanicals. Among the tested botanicals, all three levels of garlic extracts have a significant enhancing effect on all agronomic parameters and this was followed by the neem. From the result of this study, seed priming with naturally available plant materials were found to improve yield and yield components of malt barley where for this particular experiment, all levels of garlic performed best as compared to other priming materials.

Environmental pollution not only alters the environment but also changes the growth rate of various flora and fauna. Due to the irresponsible disposal of waste materials, the environment is going to be more and more polluted. Discharge of hydrocarbons in the water bodies is contaminating the water sources. These hydrocarbons are affecting the living organism. The solution to this problem has been found too expensive with little effects. To overcome this problem, some biological methods are introduced, in biological method; microbial degradation of hydrocarbons is the most promising method. The proposed study aimed to isolate and identify hydrocarbon-degrading bacterial species from the Mathura refinery, Mathura U.P. India. These species were isolated from petroleum-contaminated refinery water and grew on nutrient agar media, identified according to their distinct morphological, and biochemical characteristics, with16s rRNA sequencing. Results of this study confirmed the presence of various bacterial isolates such as Brevibacillus nitrificans, Algoriphagus shivajiensis, Bacillus marisflavi, Acinetobacter junii, Pseudomonas pseudoalcaligenes, and Bacillus pumilus from the collected samples based on the Bushnell Haas method and separation funnel method. Further, identified bacteria were tested for the maximum hydrocarbon degradation capacity in liquid culture, and results of the Gas Chromatography-Mass Spectrometry (GC-MS) suggested that only two bacterial species viz., P. pseudoalcaligenes and B. pumilus having the maximum hydrocarbon degradation capacity.

Web Accessibility means that websites, tools, and all technologies are designed in an accessible way for all people regardless of any disability and other physical limitations. The number of disabled people is far greater than anyone could estimate. The importance of online education cannot be ignored as it can provide access to a range of educational material available over the internet. There is now much discussion about the issue of E-accessibility when it comes the to the design and development of the website and it is becoming a legal requirement for governmental and public websites to conform with the standards defined by the world wide web consortium (W3C), an organization which provides guidelines to maintain World Wide Web and its standards. Research proved that there is very little importance given to the issue of E-accessibility for people with special needs. The aim of this research is therefore to measure the accessibility level of the educational websites in the UAE against the standard defined by W3C and to form recommendations on how to improve and achieve the highest level of e-accessibility for students with special needs learners as it provides them easy access to a wider range of educational material. Enabling a website to meet the needs and requirements of special students is a concern for all educational institutions.

With the development of teacher education MOOCs, more and more schools encourage teachers to participate in MOOC. How to improve the learning effect of teachers has practical significance. Previous researches have mainly focused on the individual teachers who participate in the study alone. Little research has been done on the learning effects of the teacher groups. In this study, we adopt ANOVA and social network to analyze the differences in learning effects between teachers who participate in learning alone and teacher groups in a teacher education MOOC, and used interview to explore the causes of the differences. Results indicated: 1) the completion rate and excellence rate of group teachers are higher than individual teachers. Among them, the leader-guided teachers have higher academic performance. 2) in the forum, group teachers are more active. Effective strategies for teachers learning include three aspects: playing the exemplary role of model teachers, teachers establish a learning community, and the school establishes a learning support mechanism.

Introduction. We can confidently say already that in the current conditions of global economic development, China is the most important and priority partner in the development of our country’s foreign economic activity. Theoretical analysis. The development of a strategic approach to bilateral economic cooperation with China is the most relevant in the modern system of coordinates of Russia’s foreign economic activity. Nowadays China is really the most important and priority partner in the issues related to the development of our country’s foreign economic activity. There have been different stages in the history of relations between Russia and China, but their current state gives hope for even greater mutually beneficial effect in the strategic perspective. The need to study the formation, transformation and development of Russian-Chinese relations in the context of foreign economic relations and projects is due to the growing influence of China in Russia over the past four years, the cooling of relations between Russia and the West after the events of 2014 and the Russian “turn to the East”. Empirical analysis. Speaking about the effectiveness of foreign trade relations between Russia and China in 2019, it should be noted that Russia’s trade turnover with China in 2019 increased by 3.4% to $110.76 billion, including Russia’s exports to China increased by 3.2% to $61.05 billion, imports from China to Russia increased by 3.6% to $49.7 billion. In comparison, the trade turnover between China and the United States fell by 14.6% to $541.22 billion againist the background of a trade war between these countries. It amounted to USD 541.22 billion, with USD 418 billion coming from China to America. Results. The prerequisites and factors for further development of relations and deepening of trade and economic cooperation between Russia and China have recently been growing. In addition to classical factors: geographical, territorial and, consequently, common border, which allows the development of new forms of cooperation and business (cross-border trade, cross-border economic zones and clusters, interbank settlements in national currencies in border areas, etc.). Political factors are increasing, as well as the impact of modern world economic trends on deepening bilateral economic relations between the countries. However, it is important to remember that in today’s realities Russia needs China more than China needs Russia.

Introduction. The factor of a sharp slowdown in economic growth in almost all countries since the beginning of 2020 has been quite atypical. Whereas previously we had seen shocks mainly related to economic processes, this time the “black swan” was a public health emergency – the new coronavirus pandemic COVID-19. A feature of this crisis was the unprecedented measures of states to restrict the movement of citizens, as well as the suspension of the activities of both industrial enterprises and enterprises in the sphere of trade and services. The aim of this work is to make cross-country comparisons of the impact of increased unemployment caused by the COVID-19 pandemic on different countries’ economic growth. Theoretical analysis. The relationship between the actual output gap and potential and cyclical unemployment rates has traditionally been studied according to the well-known law of A. Okun. Okun’s Law can be viewed as a linear algebraic equation for the function of real gross domestic product (GDP). The essence of the law is that with an increase in cyclical unemployment, total output should decrease, since the number of people employed in GDP production falls. Empirical analysis. Cross-country comparisons of economic growth and characteristics of the labor market in Russia, the USA, China, Canada and Germany from 2000 to 2020, including the period of the new coronavirus infection pandemic, were carried out. Results. Based on the analysis of time series of GDP and the unemployment rate, it is shown that, depending on the depth and effectiveness of state support measures for business in terms of maintaining employment, deviations of the actual values of GDP from those calculated in accordance with Okun’s empirical law are observed. The largest and smallest deviations in real GDP changes from the predictions for the first half of 2020 have been recorded in Germany and Canada, respectively.
