Authors: Litovchenko V I , Shmeleva Zh N 
Published: December 2020

Abstract
In 2020 the world has faced the pandemic situation with COVID-19 that caused a vast amount of challenges for many spheres of human life including the system of higher education. Students and faculty members of higher educational institutions were forced to critically change their learning style using distant technologies, Zoom and Moodle platforms which was not always perceived positively. Nevertheless, the existing situation of restrictions revealed larger opportunities for an increase in English learning and education through English. One of the most popular directions is English as a medium of instruction (EMI). The international character and popularity of English are undisputable, that’s why it is widely used to teach specific subjects in non-native English-speaking countries. Institutions of higher education all over the world start offering educational programs in English for disciplines in different training directions whether it is management or agriculture. The article aims at focusing on implementing EMI in two institutions of higher education in the Siberian Federal District where faculty members teach in English within modern European internationalization trend of offering courses and Master degree programs in English. The authors make an attempt to reveal advantages and disadvantages of EMI implementation and introduction. Based on the works and experiments of foreign scientists and having some experience in using English as a medium of instruction, the authors draw the conclusion that the EMI implementation in its pure form has certain imperfections. Consequently, the authors suggest the set of measures to make this process more effective: first, to search for opportunities for the foreign language additional study by students in the Bachelor’s degree, via elective courses, or Language Learning Business Centers; secondly, to use the so-called CLIL-ised EMI; thirdly, to provide faculty members with English-training courses and ensure the access to the resources for the development of methodological materials.

Published: December 2020

Abstract
The modern education system should provide the society with a confident transition to the digital era. Digitalization contributes to the immediate response to any emergency. Consequently, the introduction of digital technologies plays an important role in the training of rescuers. The significance and ways of introducing digital technologies in the process of professional training of universities teaching fire-safety specialists have been analyzed in the article. It is emphasized that the system of training future specialists requires the use of innovative methods of training. The experience of leading universities is analyzed, where various training programs, electronic textbooks and simulation facilities are used. The role of pedagogical technologies based on students’ own activity, interactive communication, teamwork, group and individual reflection is growing. At the stage of the specialist’s training, the situation of possible emergency situations is simulated and the student is placed in conditions in which the personal qualities necessary for professional activity will be developed. The variety of forms for organizing educational activities in the conditions of digitalization will increase significantly, if they acquire a dynamic character (shift groups, spatially distributed training teams, various scenarios of rapid transition from group to individual activities and vice versa).

Authors: Solodikhina M V , Odintsova N I , Odintsova E E 
Published: December 2020

Abstract
Logic is the basis of both critical thinking and the scientific method of nature cognition, so it can be effectively developed when studying natural science disciplines. The existing tools for assessing logical thinking require a lot of time to work with materials that are barely related to natural science. Instead, it is proposed to use natural science cases, which can serve simultaneously as both a development tool and a diagnostic tool for logical thinking. The aim of the study was to test the criterion validity of such cases for assessing logical thinking. The study involved students of the Master’s program “Modern Natural Science” of the Moscow Pedagogical State University and the bachelor’s program of the Peoples’ Friendship University of Russia. The diagnostic results showed a high degree of correlation between the results obtained by the subjects when solving cases with the results of four independent assessments: Test of Logical Thinking, the Group Assessment of Logical Thinking, solving a set of logical problems and expert assessment of students’ work on a natural science project.

Rational and semi-rational solutions to the asymmetric Nizhnik–Novikov–Veselov system
Authors: Guo Lijuan , He Jingsong , Mihalache Dumitru 
Published: December 2020

Abstract
In this paper, we use the binary Darboux transformation technique to derive an uniform mathematical expression of all kinds of solutions to the (2 + 1)-dimensional asymmetric Nizhnik–Novikov–Veselov system. For the same seeding solution, a family of eigenfunctions associated with the same eigenvalue is obtained, which is used to construct rational and semi-rational solutions. Interestingly, there exists a category of localized rational solutions that show nontrivial interaction scenarios, namely the pulses undergo a scattering process after the head-on collision. The semi-rational solutions are characterized by two generic evolution scenarios: fission and fusion processes. We also find a subclass of dark rogue waves, namely trains of line solitons that evolve to significant strongly localized transient waves.
Pressure and flow statistics of Darcy flow from simulated annealing
Authors: Westbroek Marise J E , King Peter R , Vvedensky Dimitri D , Schwede Ronnie 
Published: December 2020

Abstract
The pressure and flow statistics of Darcy flow through a three-dimensional random permeable medium are expressed as a path integral in a form suitable for evaluation by simulated annealing. There are several advantages to using simulated annealing for this problem: (i) any probability distribution can be used for the permeability, (ii) there is no need to invert the transmissibility matrix which, while not a factor for single-phase flow, offers distinct advantages for multiphase flow, and (iii) the action used for simulated annealing, whose extremum yields Darcy’s law, is eminently suitable for coarse graining by integrating over the short-wavelength degrees of freedom. We show that the pressure and flow statistics obtained by simulated annealing are in excellent agreement with those obtained from standard finite-volume calculations.

Authors: Yeluri Sesha Choudary , Yadav Nishant 
Published: December 2020

Abstract
Aggregates are the furthermost vital components of concrete, but there is a need for replacement of these natural resources due to the insufficient availability of the materials. To overcome the difficulty of materials and to develop sustainable concrete, much research has been conducting to date. The replacement of aggregates wholly or partially is one of the best alternatives to this problem. To develop sustainability in concrete waste materials that are causing depletion to the environment are used as alternative materials. Rubber tire waste is one such material which is causing a lot of greenhouse gas emission. This paper reviews the use of rubber tire waste as aggregates in geopolymer concrete which shows the effect of various sizes of rubber, untreated and treated rubber aggregate on various properties such as Fresh Properties where flow values of mortar reduced with escalation in the rubber and workability of the mortar and concrete increased. Nevertheless, the Mechanical Properties shows a decrement in compressive strength, and tension properties show an increment. There is a significant amount of increment in the possessions of mortar and concrete after the crumbed rubber treated. The loss of strength for the small amount of replacement of rubber, which is 5-10% shows the strength higher than the standard concrete. The outcomes show that the custom of the rubber in concrete primes to a substantial amount of strength loss, but the addition of mineral admixture and superplasticiser helps us to achieve the geopolymer mortar and concrete applications in the field of construction.

Published: December 2020

Abstract
With an unprecedented intensification in mobile customer and mobile multimedia services radio telecommunications in general the need for more bandwidth is escalating every day. To accommodate such a large amount of wireless technologies huge bandwidth is needed. This necessitated the need to address spectrum scarcity as the spectrum is a scarce resource. But it is evident from many gamut measurement studies that much of the gamut is used in an inefficient way and its fullest potential is not exploited. This gives rise to the technology of cognitive radio networks. Having said this let us try to brief the operation of intelligent radio networks (CRN). The overview of this paper presents a detailed account of the concept of gamut sensing which a crucial step in CRN is. We address the different performance metrics related to spectrum sensing and present a brief idea of some of the research activities that are related to spectrum sensing by different researchers.
Analysis of Dynamic Frequency Reuse Techniques in LTE – A Cellular Network
Authors: Karthika S , Indumathi P 
Published: December 2020

Abstract
Inter-cell Interference (ICI) is a significant obstacle which is degrading the efficiency of mobile cellular networks particularly for end users. Frequency reuse is an ICI synchronization technique which helps to mitigate ICI by assigning dissimilar frequency reuse factors on the basis of its position to User equipment (UE). This paper proposes a Self-organized resource allocation (SORA) framework that chooses the reuse factors randomly. The output of this strategy is configured using MATLAB and correlated with numerous reuse factor combinations. Results from simulation show improved efficiency for Cell Edge Users (CEU).
The effect of pre-heat and post-heat treatment on the hardness and blackening process of electroless NiP deposits on titanium alloy
Authors: Alhaji A , Sadeghi B , Kamali S 
Published: December 2020

AbstractThe black coatings were fabricated via electroless NiP deposits on Ti-6Al-4V alloy substrate with heat-treatment and blackening process. Two types of coatings were obtained: coatings with heat-treatment after blackening and coatings with blackening after haet-treatment. After parameter optimization, the temperature and pH of the solution were adjusted to 85 °C–95 °C and 4.3–4.7, respectively. The substrate was coated after the addition of modifying components to the solution. After refluxing the samples, the blackening process was done for 40 s in nitric acid (9molar). An SEM-EDS analyze used to assess the morphology and chemical composition of the coating. Moreover, adhesion strength and optical absorptance of the coating were measured by Pull Of test and Shimadzu UV-3100 analysis, respectively. The optical absorptance was measured by 0.89 and 0.95, respectively, for Oxalic acid and Nitric/Flouridric acid pretreated samples. Results showed that heat-treatment after blackening causes coating with higher micro-hardness and optical absorption. The blackened electroless NiP coating on Ti substrate with the heat-treatment of 4 h after the blackening process provided high solar absorption of 0.99, which is exceptionally suitable as a solar absorber coating for space and allied applications.
Multi–layer graphene folds supported on a substrate: a variational model
Authors: Aljedani Jabr , Chen Michael J , Cox Barry J 
Published: December 2020

Abstract
A mathematical model is developed to study the folding behaviour of multi–layer graphene sheets supported on a substrate. The conformation of the fold is determined from variational considerations based on two energies, namely the graphene elastic energy and the van der Waals (vdW) interaction energy between graphene layers and the substrate. The model is nondimensionalized and variational calculus techniques are then employed to determine the conformation of the fold. The Lennard–Jones potential is used to determine the vdW interaction energy as well as the graphene–substrate and graphene–graphene spacing distances. The folding conformation is investigated under three different approximations of the total line curvature. Our findings show good agreement with experimental measurements of multi–layer graphene folds from the literature.
Electrochemical modification at multiwalled carbon nanotube electrodes with Azure A for FAD- glucose dehydrogenase wiring: structural optimization to enhance catalytic activity and stability
Authors: Tsujimura Seiya , Tanaka Shunya , Gross Andrew , Holzinger Michael 
Published: December 2020

Abstract
Electrochemical grafting is a suitable technology for fabricating electrode surfaces with new chemical functionalities whilst maintaining the bulk properties of the electrode, and electrochemical amine oxidation and diazonium salt reduction are two widely used techniques to achieve this end. Herein, we report the electrochemical reductive grafting of Azure A onto multiwalled carbon nanotube (MWCNT) electrodes for the efficient wiring of flavin adenine dinucleotide (FAD) dependent glucose dehydrogenase. The diazonium salt of Azure A is formed in situ and subsequently grafted onto the electrode surface through electrochemical reduction. The formal potential of the resultant Azure-A-modified electrode shifted to −0.05 V vs. Ag/AgCl upon radical coupling to the MWCNT electrode. Electron transfer from FAD buried in the protein shell to the electrode via Azure A was then observed in the presence of glucose in the buffer solution. This study focused on the important effect of CNT mass loading on Azure-A loading as well as bioelectrocatalytic activity and storage stability. The three-dimensional porous structure of the MWCNT electrode was determined to be favorable for the immobilization of flavin adenine dinucleotide dependent glucose dehydrogenase and efficient electron transfer via the Azure-A functionalities. The optimized 300 µg CNT-loaded modified electrode on glassy carbon (3 mm diameter) retains its initial activity for 3 d and 25% of its initial activity after 10 d. Furthermore, we show that grafted Azure A is stably immobilized on the MWCNTs for 1 month; therefore, the limiting stability factor is enzyme leaching and/or deactivation.
