De testemunha à protagonista
Authors: Schvarzman Sheila
Published: November 2021

Beatriz Roquette Bojunga (1911-1999) atuou por 30 anos no Instituto Nacional de Cinema Educativo, o INCE (1936-1966). Ao longo desse período foi de secretária a diretora da filmoteca e executou atividades ligadas à organização da produção e divulgação dos filmes da primeira produtora oficial do país. Braço direito de Humberto Mauro, ao contrário do que se estabeleceu na bibliografia, ela também participava de filmagens. Assim, menos do que uma faz-tudo, como designava sua função, ela teria sido o que se denomina hoje ‘diretora de produção’ do INCE e sua divulgadora, atuando, assim, como mediadora cultural entre a instituição, especialistas e o público que ajudou a criar. É o que se busca mostrar neste artigo, levando em conta o silêncio no relato de Bojunga sobre seu estatuto no INCE – devido à irrelevância atribuída às atividades profissionais de mulheres, pelos homens e pelas próprias mulheres, e à escassez de documentação escrita sobre sua atuação. No entanto, se os interditos apontam questões de gênero, estes são atravessados e toldados pelo pertencimento social.

Published: November 2021

Many companies in Bulgaria are defined themselves as Social enterprises (SE). The process of arising of new SE and their stop of working is a significant challenge. The situation with SE is very dynamic and their real status should be studied to estimate their impact on the Bulgarian economy. Here we describe the real picture of SE in Bulgaria, based on officially published data. In result of data analysis we make conclusions and estimations in order to stabilize these processes. The strong dominance of Sofia (Capital) was detected in both Non-financial (NFE) and Non-for-profit (NPE) sectors of SE. It could be further ascertain if the operations are really in Sofia city or only their registration. Lightly positive trend was found in the number of both NFE and NPE. Highly negative was the trend in the number of employees engaged in NFE, while the NPE sector remained relatively stable. This deviation in employment rate could be explained by a type of funding: NPE were funded predominantly by state or EU projects, while NFE tried to keep the enterprises and balanced by lowering the personnel, probably due to insufficient financing and economic crisis. In conclusion, more attention in needed by the government and the EU regarding the funding of NFE.

Criminal Law Measures Providing for the Treatment of Socially Significant Diseases: a Mandatory Application or a Selective Addition
Authors: Merkuryev Viktor , Zvonov Andrey , Yakovlev Andrey
Published: November 2021

Modern society faces a serious problem of preserving the health of people. Currently, there are some wide-spread diseases that are highly dangerous because they are easily transmitted and have a high mortality rate. These diseases compose a group of socially significant diseases, their list is approved by the Decree of the RF Go­vernment of Dec. 1, 2004 No. 715. One of the key institutes of counteracting the spread of socially significant diseases is the institute of criminal law measures. A number of clauses of the RF Criminal Code regulate mandatory treatment of criminally liable persons. The use of criminal law measures is regulated by Art. 72.1, 73, 79, 82.1 and Ch. 15 of the RF Criminal Code, while Art. 18 of the RF Penitentiary Code determines the procedure of using medical measures to treat persons sentenced to punishments involving isolation from the society. However, the non-mandatory and ambiguous procedure of prescribing mandatory treatment for socially significant di­seases through criminal law means creates difficulties in organizing a comprehensive approach to treating such diseases. In the process of their research, the authors ascertained that it is necessary to adopt an uncompromising approach in prescribing treatment of a socially significant disease by using criminal law measures to a person suffering from such a disease. This goal could be achieved by replacing the phrase «could hold accountable» to «holds accountable» in the clauses of Art. 72.1, 73 and 79 of the RF Criminal Code. It is suggested that the legal limitation of the use of mandatory treatment for convicts isolated from the society should be abolished by elimina­ting the words «which is connected with danger to themselves or other persons» from Part 2, Art. 18 of the RF Penitentiary Code. Related problems arise during the mandatory treatment of psychiatric disorders that are socially significant diseases too. Thus, the elimination of legal problems of treating socially significant diseases through criminal law measures will increase the effectiveness of criminal legislation from the standpoint of its social function — the protection of the society and its representatives.
Suitability of bio-extracts with coating materials on physicochemical quality of tomato fruits (Solanum Lycopersicum L.) stored at ambient temperature
Authors: Desta Dugassa Fufa
Published: November 2021

Tomato (Solanum Lycopersicum L. (or) Lycopersicon esculentum Mill.) is being a very nutritious and health protective food, are highly perishable nature. Its sensitivity to postharvest loss due to poor handling, diseases and physical injury limits its successful marketing. Therefore, simple technology is required to reduce the postharvest loss of this commodity. The use of edible coatings with bio-extracts appears to be a good alternative preservation technique to extend the mature tomato fruits. This study was, therefore, initiated to investigate the effect of using bio- extracts garlic bulba and capsicum incorporation with coating materials (maize starch and beeswax on physicochemical quality of tomato fruit stored at ambient conditions (temperature 15.5 to 20.2oC and relative humidity of 55.5 to 67.3%). The experiment was conducted using complete randomized design of two varieties (Fetane and Melkashola) and six treatments. The tomato fruits were coated by dipping into solution for 3 minutes. The treatments prepared were on coating solution of MGE( 9.5% maize starch with 0.5% garlic extract), MCE (9.5% maize starch with 0.5% capsicum extract), BCE (9.5% beewax mixed with 0.5% capsicum extract), BGE (9.5% beewax mixed with 0.5% garlic extract), 10% maize starch without bio-extract, 10% beewax without bio- extract and control. The treatment means were tested at significance level of P ≤ 0.05. The effectiveness of bio-extracts with coating materials on physicochemical quality of tomato fruits were evaluated at three days intervals for 30 days. There was a significance difference (P<0.05) between coated and uncoated fruits. All coatings delayed tomato ripening and improved the keeping quality parameters but best results were exhibited by 9.5% with 0.5% BCE followed by 9.5% with 0.5% MGE by maintaining the mature tomato fruit for 30 days. The study showed that the Fetane variety has maintained more quality attribute than Melkashola variety during storage.

Published: November 2021

The neighborhood renewal process is an important opportunity to update the built environment; however, major changes to the built environment might decrease spatial performance and environmental quality. In these processes, there is a need to evaluate urban renewal alternatives, especially the quality of the environment, to understand the performance of the newly designed built environment. The quality of the built environment depends on a variety of aspects (such as walkability, energy level, security, open spaces, water permeability, etc.), several of which can be assessed using diverse measurements and evaluation models. Current new technological developments, based on GIS, enable the evaluation of diverse aspects of environmental quality and promote urban renewal decision-making processes. Urban renewal needs to harness these models in the decision-making approaches to improve assessment processes of urban renewal alternative estimations that consider future performance and quality of the built environment. In this article, we present a 3D-GIS multiparametric scenario analysis for neighborhood renewal alternatives estimation to evaluate the performance and quality of the built environment as part of the decision-making process. The multiparametric approach will include an evaluation analysis of several aspects of environmental quality, including walkability, accessibility, sense of security, energy, shade, water infiltration, visibility, and more. The analysis results will indicate the level of performance for each aspect as indices for environmental quality. The multiparametric scenario analysis for neighborhood renewal will be conducted on three renewal alternatives for one neighborhood in the city of Hatzor HaGlilit, Israel.

Area-Based Urban Renewal Approach for Smart Cities Development in India: Challenges of Inclusion and Sustainability
Authors: Praharaj Sarbeswar
Published: November 2021

Cities in the Global South face rapid urbanization challenges and often suffer an acute lack of infrastructure and governance capacities. Smart Cities Mission, in India, launched in 2015, aims to offer a novel approach for urban renewal of 100 cities following an area-based development approach, where the use of ICT and digital technologies is particularly emphasized. This article presents a critical review of the design and implementation framework of this new urban renewal program across selected case-study cities. The article examines the claims of the so-called “smart cities” against actual urban transformation on-ground and evaluates how “inclusive” and “sustainable” these developments are. We quantify the scale and coverage of the smart city urban renewal projects in the cities to highlight who the program includes and excludes. The article also presents a statistical analysis of the sectoral focus and budgetary allocations of the projects under the Smart Cities Mission to find an inherent bias in these smart city initiatives in terms of which types of development they promote and the ones it ignores. The findings indicate that a predominant emphasis on digital urban renewal of selected precincts and enclaves, branded as “smart cities,” leads to deepening social polarization and gentrification. The article offers crucial urban planning lessons for designing ICT-driven urban renewal projects, while addressing critical questions around inclusion and sustainability in smart city ventures.

Authors: Mykhailova Oksana , Humankova Olga , Grygorieva Tetiana
Published: November 2021

The article deals with a thorough analysis of drama techniques in teaching English to primary school learners.
The review of literature on the problem under discussion has enabled the authors to conclude that using drama in the process of teaching English is a powerful teaching tool that promotes the development of creativity in the learners and enhances cognitive interest in learning a foreign language. Theoretically, however, the problem is underinvestigated in the Ukrainian context; so, the topicality of the research is ensured by existing difficulties in using drama in teaching English to primary school learners. The challenges are mainly caused by the lack of specially designed tasks for this purpose. Hence, the goal of this article is to outline the theoretical prerequisites and develop a methodologically grounded system of exercises and tasks to use drama in teaching English to primary school learners. The methodology of the research relies on the analysis of the available literature on the issue under investigation, with age and psychological characteristics of primary school learners considered. The paper discusses the approaches to defining the concept of dramatization and reveals the essential characteristics of dramatization in the process of teaching English to primary school children. The authors provide a detailed analysis of the classroom benefits of using drama techniques in teaching English to primary school learners and illustrate them by offering a lesson designed for primary school learners. The material used for the lesson designing is based on the educational and language capacity of fairy tales. The paper concludes that a positive effect of using drama in the primary school classroom contributes to enhancing both language and cognitive skills of young learners.

Published: November 2021

Treatment of psoriasis (Ps) is still one of the most difficult tasks of practical medicine. The disease often affects young and able-bodied people, and the process itself has a persistent and progressive nature, not amenable to treatment by traditional methods. PS as a systemic disease is based on the phenomena of chronic nonspecific skin inflammation with intracellular edema, infiltration, microcirculatory and metabolic disorders. PS is also characterized by disorders of oxidative processes in skin cells and in the system of free-radical oxidation of lipids. The study of immune status in PS patients revealed disorders of circulating immune complexes (CIC), in particular immunoglobulins A, M, G, against the background of suppressed cellular immunity and phagocytic activity of neutrophils.

In pronounced pain syndrome the most important functional shifts (the generators of pathologically increased excitement) by recording somatosensory generated potentials arc revealed at higher levels than in slight tenderness. At the same time in slight painfulness tenderness a great number of the generators of mild activity arc found, showing insufficient activity of antinociceptive system. After treatment a number of the generators of pathologically increased excitement decrease, at the same time the migration to the caudal parts of nervous system occurs. The neurophysiologic basis for possible worsening myofascial pain syndromes is created.

Application of electrostimulation in the treatment of pain syndrome in diseases of the peripheral nervous system
Authors: Kazarov S. V.
Published: November 2021

Diseases of the peripheral nervous system account for almost half of the neurological morbidity of the adult population. One of the leading clinical signs of peripheral nervous system disorders is pain. With all the commonplace simplicity of the concept "pain", the scientific definition of this specific feeling is associated with significant difficulties of epistemological nature. One of the essential moments of correct understanding and estimation of pain phenomenon is its division into primary and secondary, which is based on the classification suggested by Gode in 1881, which distinguishes protopathic and epicritic pain, that is identical to division of pain into acute and chronic.

Adaptando a ensinanza aos tempos de pandemia: da presencialidade ao modelo educativo online
Authors: Pardo Cristina
Published: November 2021

A materia obrigatoria de "Deseño, planificación e avaliación de propostas didácticas de Tecnoloxía na Educación Secundaria” pertence ao Máster Universitario en Profesorado de Educación Secundaria Obrigatoria, Bacharelato, Formación Profesional e Ensinanza de Idiomas (Itinerario: Tecnoloxía) da Universidade da Coruña. Neste traballo descríbese a adaptación de dita materia ás medidas promulgadas pola Xunta de Galicia para paliar a terceira onda da pandemia provocada pola COVID-19. Froito destas medidas, a materia tivo que mudar do modelo presencial ao modelo educativo online. A experiencia vivida con este cambio e as principais conclusións ás que se chegou, son descritas neste traballo. Destácase que para realizar as sesións virtuais é necesario re-programar as actividades e o horario das mesmas con respecto ás sesións presenciais, debido ás limitacións que algúns alumnos teñen para acceder a internet e á baixa interacción dos estudantes no modelo de ensino virtual. Ademais, a motivación e os resultados acadados no proceso de ensino-aprendizaxe por parte dos alumnos diminuíron con respecto ás sesións presenciais. Polo tanto, con esta experiencia, conclúese que a docencia baseada en clases presenciais ten máis éxito que a ensinanza baseada só en sesións virtuais, aínda que en ambas as dúas ensinanzas se usen metodoloxías activas co alumnado

Neste traballo presentamos unha análise dos resultados obtidos nos exames finais da materia de Fisioloxía Humana durante a COVID-19, materia impartida no grao de podoloxía da UDC. Estes resultados comparáronse cos obtidos en cursos anteriores en exames levados a cabo de xeito presencial. En todos os casos os resultados proceden de exames tipo test de resposta única. Para levar a cabo esta análise tivéronse en conta os cursos académicos 2017/2018 e 2018/2019, no que analizamos os resultados de 165 exames realizados de xeito presencial e comparámolos cos resultados de 46 exames realizados virtualmente no curso académico 2019/2020. Non se observaron diferencias na cualificación media obtida en ambas modalidades de exames. Non obstante, nos exames virtuais diminúe lixeiramente a porcentaxe de alumnos non presentados e a porcentaxe de suspensos e tres veces máis baixa, sen embargo, tamén diminúe o número de estudantes que obteñen sobresaínte. En base a estes resultados podemos concluír que os exames tipo test virtuais aumentan o número de estudantes que supera a materia, pero non así a nota global da mesma

Authors: Viñas-Diz Susana , Vivas-Costa Jamile
Published: November 2021

En tiempos de pandemia la "videoconferencia" se convierte en uno de los sistemas más utilizados para estar en contacto con los alumnos de manera síncrona. Se utiliza para impartir docencia, realizar tutorías grupales/individuales, e incluso examinar de contenidos prácticos a grupos pequeños de alumnos. El inicio del 2º cuatrimestre del curso académico 2020-21 lo hemos empezado en una situación de confinamiento, donde profesores y alumnos no hemos podido acudir de manera presencial a las aulas, esta situación se ha desarrollado desde el 8 de febrero- hasta el 1 de marzo, fecha a partir de la cual se ha podido retomar de manera presencial la impartición de determinados contenidos. Durante estas 5 semanas de no presencialidad en las aulas, en una de las asignaturas del Máster en Discapacidad y Dependencia (MDD) se ha optado por impartir los contenidos teóricos a través de videoconferencia, utilizando esta no sólo como recurso de comunicación síncrona, sino como recurso didáctico en sí mismo. El objetivo de este trabajo es conocer la opinión de los alumnos matriculados en la asignatura de "Bases y principios en neurociencia y rehabilitación neurológica" curso 2020-21 sobre la utilización de un sistema de enseñanza semipresencial basado en la combinación de videoconferencia y clases presenciales. Haciendo especial hincapié en la valoración de la videoconferencia (a través de microsoft teams) como recurso didáctico.
OPERAÇÕES DESCONTINUADAS EM RESPOSTA À DIVERSIFICAÇÃO: UMA ANÁLISE DAS COMPANHIAS BRASILEIRAS LISTADAS NA B3
Authors: Oliveira Natália Garcia , Cruz Niara Gonçalves , Pinheiro Laura Edith Taboada , Francisco José Roberto Souza
Published: November 2021

O objetivo desta pesquisa é identificar a relação entre a diversificação corporativa e a descontinuidade de operações em empresas brasileiras, listadas na B3 no período de 2011 a 2018. A partir da década de 1980, verificou-se que a estratégia de diversificação não se mostrou eficaz (NAKAO, 2000). Algumas empresas começaram a desfazer suas composições, formadas pelas diversas aquisições ou criações internas, resultando em desinvestimentos. No Brasil, tais operações são pelo Comitê de Pronunciamentos Contábeis – CPC 31: Ativo não circulante mantido para venda e operações descontinuadas. Para atender ao objetivo, foram analisados dados de 95 empresas brasileiras, não financeiras, listadas na B3, que contabilizaram pelo menos uma operação descontinuada no período de 2011 a 2018. O modelo econométrico utilizado foi o Logit em painel. Os resultados encontrados permitem inferir que a diversificação corporativa influencia positivamente a probabilidade de as empresas descontinuarem operações. Adicionalmente, verificou-se que empresas maiores são menos propensas a descontinuarem operações, por outro lado, empresas que possuem maior desempenho estão mais propensas a descontinuarem operações. Esta pesquisa pretende contribuir para ampliar o debate sobre operações descontinuadas no Brasil. Trata-se de um tema incipiente e pouco explorado pelos pesquisadores.

Published: November 2021

The pathological research and drug development of brain diseases require appropriate brain models. Given the complex, layered structure of the cerebral cortex, as well as the constraints on the medical ethics and the inaccuracy of animal models, it is necessary to construct a brain-like model in vitro. In this study, we designed and built integrated three-dimensional (3D) printing equipment for cell printing/culture, which can guarantee cell viability in the printing process and provide the equipment foundation for manufacturing the layered structures with gradient distribution of pore size. Based on this printing equipment, to achieve the purpose of printing the layered structures with multiple materials, we conducted research on the performance of bio-inks with different compositions and optimized the printing process. By extruding and stacking materials, we can print the layered structure with the uniform distribution of cells and the gradient distribution of pore sizes. Finally, we can accurately print a structure with 30 layers. The line width (resolution) of the printed monolayer structure was about 478 μm, the forming accuracy can reach 97.24%, and the viability of cells in the printed structure is as high as 94.5%.
3D Printing Polymer-based Bolus Used for Radiotherapy

Published: November 2021

Bolus is a kind of auxiliary device used in radiotherapy for the treatment of superficial lesions such as skin cancer. It is commonly used to increase skin dose and overcome the skin-sparing effect. Despite the availability of various commercial boluses, there is currently no bolus that can form full contact with irregular surface of patients’ skin, and incomplete contact would result in air gaps. The resulting air gaps can reduce the surface radiation dose, leading to a discrepancy between the delivered dose and planned dose. To avoid this limitation, the customized bolus processed by three-dimensional (3D) printing holds tremendous potential for making radiotherapy more efficient than ever before. This review mainly summarized the recent development of polymers used for processing bolus, 3D printing technologies suitable for polymers, and customization of 3D printing bolus. An ideal material for customizing bolus should not only have the feature of 3D printability for customization, but also possess radiotherapy adjuvant performance as well as other multiple compound properties, including tissue equivalence, biocompatibility, antibacterial activity, and antiphlogosis.
Using Spheroids as Building Blocks Towards 3D Bioprinting of Tumor Microenvironment
Authors: Zhuang Pei , Chiang Yi-Hua , Fernanda Maria Serafim , He Mei
Published: November 2021

Cancer still ranks as a leading cause of mortality worldwide. Although considerable efforts have been dedicated to anticancer therapeutics, progress is still slow, partially due to the absence of robust prediction models. Multicellular tumor spheroids, as a major three-dimensional (3D) culture model exhibiting features of avascular tumors, gained great popularity in pathophysiological studies and high throughput drug screening. However, limited control over cellular and structural organization is still the key challenge in achieving in vivo like tissue microenvironment. 3D bioprinting has made great strides toward tissue/organ mimicry, due to its outstanding spatial control through combining both cells and materials, scalability, and reproducibility. Prospectively, harnessing the power from both 3D bioprinting and multicellular spheroids would likely generate more faithful tumor models and advance our understanding on the mechanism of tumor progression. In this review, the emerging concept on using spheroids as a building block in 3D bioprinting for tumor modeling is illustrated. We begin by describing the context of the tumor microenvironment, followed by an introduction of various methodologies for tumor spheroid formation, with their specific merits and drawbacks. Thereafter, we present an overview of existing 3D printed tumor models using spheroids as a focus. We provide a compilation of the contemporary literature sources and summarize the overall advancements in technology and possibilities of using spheroids as building blocks in 3D printed tissue modeling, with a particular emphasis on tumor models. Future outlooks about the wonderous advancements of integrated 3D spheroidal printing conclude this review

Additively manufactured trabecular tantalum (Ta) scaffolds are promising bone repair materials for load-bearing applications due to their good pore interconnectivity. However, a thorough mechanical behavior evaluation is required before conducting animal studies and clinical research using these scaffolds. In this study, we revealed the compressive mechanical behavior and material failure mechanism of trabecular tantalum scaffolds by compression testing, finite element analysis (FEA), and scanning electron microscopy (SEM). Trabecular tantalum scaffolds with porosities of 65%, 75%, and 85% were fabricated by laser powder bed fusion-based additive manufacturing. Porosity has a significant effect on their compressive mechanical properties. As the porosity decreased from 85% to 65%, the compressive yield strength and elastic modulus increased from 11.9 MPa to 35.7 MPa and 1.1 GPa to 3.0 GPa, respectively. Compression testing results indicate that trabecular tantalum scaffolds demonstrate ductile deformation and excellent mechanical reliability. No macroscopic cracks were found when they were subjected to strain up to 50%. SEM observations showed that material failure results from tantalum strut deformation and fracture. Most microcracks occurred at conjunctions, whereas few of them appear on the struts. FEA-generated compressive stress distribution and material deformation were consistent with experimental results. Stress concentrates at strut conjunctions and vertical struts, where fractures occur during compression testing, indicating that the load-bearing capability of trabecular tantalum scaffolds can be enhanced by strengthening strut conjunctions and vertical struts. Therefore, additively manufactured trabecular tantalum scaffolds can be used in bone tissue reconstruction applications.
O Sagrado está no Todo: Experiências de Praticantes do (Neo)Paganismo como Possibilidade de Encontro Holístico do Ser

This paper aims to understand the experiences of practitioners of Contemporary Paganism and the relationships they have with their spiritual practices, as well as to investigate how they understand and interact with nature and how they perceive themselves as practitioners of a holistic belief. From in-depth interviews with four practitioners of (Neo) Paganism, it is possible to analyze the discourses on spiritual experiences through two categories of analysis: 1. Contemporary Paganism: Worldview and Holistic Practices, and 2. Understanding Totality: Nature, Self and Community. The research made it possible to understand that the relationship between the sacred, nature and the person in (Neo) Paganism is defined by the notion of totality as a reality in which the living beings, the world and the gods are interconnected, and therefore it is understood that the person-world-sacred does not separate.

As Formas da Simpatia e o seu Papel na Compreensão das Vivências Alheias em Scheler
Authors: RAMOS Daniel Rodrigues
Published: November 2021

The objective is to describe the main features of the sympathy phenomenon from Max Scheler's phenomenology. The central problem is to show how sympathy shows itself as a privileged "place" for understanding the experiences of others, because it implies a psychic-affective unification with whom one sympathizes or welcomes. However, compassion and co-rejoicing cannot be understood as the apprehension of psychic contents unrelated to the reproduction of the feelings of the other, mistakenly equating sympathizing with affective contagion. Thus, first, some reasons and ways of transformations of anthropologies and historical consolidation of the modern ratio that led to such mistake are outlined. Then, after distinguishing the plural forms of sympathy, showing its law of internal reasoning, it is discussed in what sense sympathy is to suffer and to rejoice by spelling out its intentional structure. To know the other, however, is not only to unite affectionately with others, but the free decision, proper of a spiritual being, to take part in the opening of the personal being of others, to participate in their intentional acts. It follows, then, that sympathizing presupposes the supreme form of love. Palavras-chave : Feelings; sympathy; love; knowledge of each other.
A teoria do sonho de F. S. perls: evolução, problemas teóricos e práticos
Authors: CEBALLOS David
Published: November 2021

The dream theory created by F. S. Perls, traditionally, has been characterized as a projection or an existential message. However, this description only represents a simplistic explanation of the broader and original conceptualization of the dream phenomenon developed by Perls. In this regard, in this paper an orderly exposition of the perlsian theory of the dream is done, as well as a critical analysis of the propositions on which it is based, paying special attention to the errors inherent in it and its implications in clinical practice. It is concluded that the perlsian theory of the oneiric evolved in three stages, namely, original model of the dream, model of correspondence and classical model of the dream, each of which constitutes, in its own right, a theory of the dream in which it defines the dream phenomenon in a particular way and is attributed to specific psychological and therapeutic functions, as well as a specific work methodology.

Energy stability and electronic properties of carbon nanotorus at a localized breaking of interatomic bonds: computer modeling
Authors: Glukhova O.E. , Slepchenkov M.M.
Published: November 2021

This paper is devoted to the study of the dynamic processes that occur in the carbon nanotorus during localized breaking of interatomic bonds, and to the analysis of the influence of these processes on the electronic properties of carbon nanotorus. The object of research is a carbon nanotorus with chirality indices (13, 0) with a diameter of 20 nm and a thickness of 1 nm obtained as a result of defect-free folding of a zigzag carbon nanotube of appropriate geometric dimensions into a ring. The behavior of the nanotorus is modeled by the molecular dynamics method using a modified Brenner potential to describe the interaction between atoms. It is shown that over time, the nanotorus straightens into a nanotube, while maintaining energy stability. It is found that the process of nanotorus straightening is accompanied by the appearance of deformation wave-like bends propagating at a speed of 200 m/s along the atomic network of the structure. These bends lead to deformation of the nanotorus and numerous local breaks in the bonds between atoms. However, broken bonds are restored within a few femtoseconds before the structure relaxes in energy, therefore, in general, the atomic framework of the nanotorus remains defect-free after rectification. The results of calculating the distribution of the density of electronic states (DOS) of a nanotorus by the self-consistent charge density functional tight-binding (SCC-DFTB) quantum method showed that at the moment of localized breaking of interatomic bonds around the circumference of the tubular framework, the nanotorus loses its semiconductor properties, becoming a gapless conductor. The discovered physical phenomenon explains the process of nanotorus formation during synthesis accompanied by multiple ruptures of the nanotori and reverse closure of the nanotubes into the nanotori.

To create field emission cathodes (autocathodes) used in the manufacture of displays and other devices, carbon nanowalls (CNW) are promising. The CNW layers are a porous material consisting of curved plates formed by graphene layers. The industrial use of CNW autocathodes is impeded by the heterogeneity and instability of the magnitude and density of the cathode current. To improve the characteristics of autocathodes, an AlN film is formed on the surface of the emitting substance, which also has the property of field emission. CNW was obtained from a gas mixture of H2 and CH4 activated by a dc glow discharge. The CNW layers were deposited on silicon substrates and substrates representing a layered structure made by forming an opal matrix (OM) layer on a Si substrate. AlN films with controlled composition and structure were prepared by RF magnetron reactive sputtering. CNW layers with a thickness of > 4 μm were obtained by successive growth of two CNW layers (Si/CNW/CNW structure). An additional CNW layer was also grown on the surface of the first layer coated with Ni (Si/CNW/Ni/CNW structure). AlN films were grown on a CNW layer (Si/CNW/AlN and Si/OM/Ni/CNW/AlN structures). It is shown that CNW plates are formed from graphene layers partially connected by atomic bonds (up to 30 layers) packed in a hexagonal lattice, and AlN films consisted of amorphous and axially textured crystalline phases. The current-voltage characteristics of the autocathodes were measured in a pulsed mode at a pressure of ~10−3 Pa. The Si/CNW/CNW structures are characterized by a threshold of autoemission of ≤ 3.6 V/μm and a high density of centers of emission. The current-voltage characteristics of the layered structures Si/CNW/AlN, Si/OM/Ni/CNW and Si/OM/Ni/CNW /AlN showed better emission properties compared to the Si/CNW structure. The current-voltage characteristics considered make it possible to predict the structure and composition of the emitting layer to improve the operational characteristics of multilayer autocathodes.
