SOCIAL CONSEQUENCES OF FALSIFICATION OF SCIENTIFIC MATERIALS IN ELECTROMAGNETIC SAFETY
Authors: СПОДОБАЕВ Ю.М.
Published: July 2021

Рассматривается проблема социально-психологических механизмов поведенческих реакций населения, которая становится все актуальнее в связи с ростом социальной напряженности из-за размещения излучающих объектов современных сетевых технологий и обострением радиофобии. В качестве провоцирующего подобные ситуации фактора выделяется информационный фактор, т.е. доведение до населения результатов научно-технического и медико-биологического обоснования электромагнитной безопасности объектов связи. Приводится пример искажений и фальсификации научных результатов медико -биологических исследований, являющихся основой нормативной и методической документации. Названы социальные последствия проблемы, суть которых в том, что не просто растет недоверие специалистов и населения к системе санитарногигиенического контроля, а более того, ставится под сомнение безопасность современных технологий в целом.

The problem of socio-psychological mechanisms of behavioral reactions of the population is considered, which is becoming more and more relevant due to the growing scale of social tension around radiating objects of modern network technologies and progressive radiophobia of the population. The information factor is highlighted as a factor provoking such situations, i.e. bringing to the public the results of scientific, technical, and medico-biological justification of the electromagnetic safety of communication facilities. The example of distortion and falsification of scientific results of biomedical research, which are the basis of normative and methodological documentation, is given. The social consequences of the problem are named, the essence of which is that not only the distrust of specialists and the population to the system of sanitary and hygienic control is growing, but the safety of modern technologies, in general, is being questioned.

Published: July 2021

С развитием технологии MIMO и появлением технологии massive MIMO возросла сложность обработки сигнала на приемной стороне. Применение известных алгоритмов детектирования сигнала на приемной стороне становится трудно реализуемым из-за высокой вычислительной сложности. Предлагается новая реализация известного алгоритма МСКО, которая позволяет снизить вычислительную сложность детектирования без потерь в помехоустойчивости в системах беспроводной связи, использующих технологию massive MIMO.

With the development of MIMO technology and the appearance of the massive MIMO technology, the computational complexity of signal processing on the receiving side has increased. The application of known signal detection algorithms used in MIMO systems becomes difficult or even impossible to implement in massive MIMO systems because of computational complexity. We offer a new realization technique of the well-known MMSE detection algorithm with less computational complexity and without any loss in noise immunity in wireless communication systems using massive MIMO technology.

Показано усложнение процесса управления волоконно-оптической инфраструктурой, обусловленное ростом связности сети, увеличением количества элементов систем связи, ростом количественных и качественных показателей оптического кабеля. При усложнении объекта управления требуется увеличить объем достоверной информации для характеристики его текущего состояния. Предлагается на всех уровнях управления результатами измерения использовать средства, реализующие интерферометрические методы и их сведение в единую базу данных, структура которой обоснована в статье. Данное решение направлено на повышение оперативности принятия адекватного решения по управлению инфраструктурой на всех уровнях управления.

The article shows the complication of the process of fiber-optic infrastructure management due to the growth of network connectivity, the increase in the number of elements of the communication system, and the growth of quantitative and qualitative indicators of the optical cable. When the control object is complicated, it is required to increase the volume of reliable information to characterize its current state. At all levels of management of measurement results, it is proposed to use tools that implement interferometric methods and their consolidation into a single base, the structure of which is justified in the article. The proposed solution is aimed at increasing the efficiency of making an adequate decision on infrastructure management at all levels of management.

Published: July 2021

The dynamics of science and technology are the primary elements of the sustainable development of society in all areas. In the educational context, they have given rise to new forms of flexible, open and free or low-cost learning, such as MOOC (Massive Open Online Courses) that, supported by emerging technologies, have a social effect and contribute to the democratization of knowledge. In this sense, the main objective of this work is to identify the implications (limitations and scope) of MOOCs for the development of an inclusive education supported by emerging technologies and their impact on society, taking into account the main factors that generate it and develop, from the STS (Science, Technology and Society) vision, through the application of historical-logical, analysis and synthesis methods and finally generalization-abstraction, taking primary and secondary bibliographic sources as important, with the purpose that the institutions educational institutions incorporate MOOC as an alternative for permanent training and updating of knowledge that the knowledge society demands so much.
Tecnología de red definida por software para el aprendizaje en grupos de investigación y educación
Authors: Silva José
Published: July 2021

Software Defined Network (SDN) is an emerging and programmable network paradigm that changes the way networks are designed and managed by introducing an abstraction that decouples control from the data plane. This technology has generated great interest in both industry and academia. SDN aims to simplify network management while allowing students, teachers, and researchers to experiment with protocols on networks that are used on a daily basis. In addition, it has led to the emergence of new trends in educational systems, especially the university sector, in computer systems and network administration. Due to the little diffusion of the SDN and the high projection that this technology currently has, it is essential that the university educational entities are those that dabble in this issue. That is why this essay is a synthesis that addresses the importance of applying SDN for educational purposes and in the context of academic research groups.
Liberating Afghan Women
Authors: Gallagher Nancy
Published: July 2021

Public opinion in the United States and elsewhere celebrated the liberation of Afghan women following the defeat of the Taliban government. The United States promised to stay in Afghanistan and foster security, economic development, and human rights for all, especially women. After years of funding various anti- Soviet Mujahidin warlords, the United States had agreed to help reconstruct the country once before in 1992, when the Soviet-backed government fell, but had lost interest when the warlords began to fight among themselves. This time, however, it was going to be different. To date, however, conditions have not improved for most Afghan women and reconstruction has barely begun. How did this happen? This article explores media presentations of Afghan women and then compares them with recent reports from human rights organizations and other eyewitness accounts. It argues that the media depictions were built on earlier conceptions of Muslim societies and allowed us to adopt a romantic view that disguised or covered up the more complex historical context of Afghan history and American involvement in it. We allowed ourselves to believe that Afghans were exotic characters who were modernizing or progressing toward a western way of life, despite the temporary setback imposed by the Taliban government. In Afghanistan, however, there was a new trope: the feminist Afghan woman activist. Images of prominent Afghan women sans burqa were much favored by the mass media and American policymakers. The result, however, was not a new focus on funding feminist political organizations or making women’s rights a foreign policy priority; rather, it was an unwillingness to fulfill obligations incurred during decades of American-funded mujahidin warfare, to face the existence of deteriorating conditions for women, resumed opium cultivation, and a resurgent Taliban, or to commit to a multilateral approach that would bring in the funds and expertise needed to sustain a long-term process of reconstruction.

Published: July 2021

Cannabis sativa L. is used as medicine and narcotic in Lesotho. Phytochemical composition and total phenolics content (TPC) for hexane, chloroform, ethyl acetate and methanol extracts of aerial parts of C. sativa were determined. Ethyl acetate extract (0.1875, 0.375 and 0.75 mg mL-1) and methanol extract (0.75, 1.5 and 3.0 mg mL-1) were evaluated for cytotoxicity, genotoxicity and modulation of cyclophosphamide (CP, 1.25 mg mL-1)- and ethylmethane sulphonate (EMS, 0.25 mg mL-1)-induced genotoxicity using Allium cepa root meristem assay. CP or EMS did not reduce mitotic index (MI) of cells, hence not cytotoxic when compared with negative control using the t-test (p>0.05), but genotoxic. Both extracts were genotoxic with methanol extract also being cytotoxic. Genotoxicity was the number of aberrant cells per 100 mitotic cells. Modulatory effect (ME) was obtained by comparing mutagen-induced genotoxicity with mixture-induced genotoxicity and expressed as the number of units of mutagen-induced genotoxicity that equalled the mixture-induced genotoxicity. ME was either positive or negative and significant only if ME = ≥ 2. Both extracts were genotoxic with methanol extract also being cytotoxic. Aberrations observed were sticky chromosomes, c-metaphase, anaphase and telophase bridges, chromosome fragments and laggards. Mixture of methanol extract with CP or EMS was more genotoxic (+ME range = 1.61-11.89) than the mutagen or extract alone which suggested synergistic interaction. Mixture of ethyl acetate extract with CP induced insignificant +ME. Mixture of ethylacetate extract with EMS was significantly more genotoxic (+ME = 2.20) than EMS only at high extract concentration. The methanol and ethylacetate extracts of C. sativa were not anti-genotoxic to CP- or EMS- induced genotoxicity. TPCs for hexane, chloroform, ethyl acetate and methanol extracts were 39831.46, 2544.94, 2438.20 and 56601.12 mg GAE/gram dry weight respectively. The differences in the cytotoxicity and MEs of the extracts were attributed to differences in phytochemical composition of extracts.

Published: July 2021

Rice (Oryza sativa L.), is a staple food and cash crop in many countries and studies on geneticstructure and differentiation patterns of rice land races along with the cultivated rice, provide important data for future rice breeding. Therefore, the aims of present investigation were 1-To study the genetic diversity present withinIranian rice genotypes, 2-To study genetic relatedness of these rice genotypes, and 3-To providebarcoding of the rice genotypes based on SSR molecular markers and produce data for rice varieties authentication. In total, 201 rice samples originated from 10 geographical regions of Iran were studied in this project. All rice samples underwent fragment analysis in every 64 SSR loci and different clustering and ordination methods performed. In general four major clusters were formed. Both landraces as well as rice cultivars were distributed in different clusters due to their genetic difference. STRUCTURE analysis of the studied genotypes followed by Evanno test produced the optimal number of genetic groups K = 2. The mean Nm = 13.6, for the studied genotypes indicates that a high degree of gene flow/ancestral common alleles are present in the rice genotypes studied. Mantel test indicated a significant positive association between genetic distance and geographic distance of the rice genotype studied and presence of an overall isolation by distance (IBD) model of differentiation across the geographical regions of Iran. Overall, the significant genetic difference observed between rice landraces and rice cultivars ofthe country may be used in future hybridization and breeding of rice in the country. The landracerice genotypes may contain useful genes to be transferred to the popular rice cultivars. Moreover, SSR loci that can differentiate rice genotypes are identified and can be used in rice cultivars authentication.

Os métodos estatísticos foram desenvolvidos como uma mistura de ciência, tecnologia e lógica para a solução e investigação de problemas em várias áreas do conhecimento. No setor da indústria, os engenheiros utilizam técnicas estatísticas com o objetivo de acompanhar o controle da qualidade dos produtos dentro de um determinado nível de aceitação. Neste artigo foram realizadas uma pesquisa quantitativa e uma pesquisa de campo em uma indústria de garrafas plásticas localizada em Miraí/MG a fim de analisar os impactos das medidas-resumo mais usuais da estatística descritivas para o setor industrial, principalmente, a variância e o desvio padrão. O aspecto estudado foi a gramatura de uma amostra de garrafas de polietileno e os trabalhos de análises estatísticas foram realizados através do Software Maple 17. Ao final do estudo, notou-se importância do estudo da variabilidade. Dentro das medidas-resumo calculadas, pode-se destacar o impacto negativo que uma alta taxa de variância acarreta a linha produtiva de uma empresa desse segmento. Um valor alto para essa variável implica em uma grande diversidade de valores para as gramaturas, provocando uma ruptura do padrão de qualidade. Portanto, para o setor industrial é primordial a pesquisa e a aplicação da estatística descritiva com o objetivo de fornecer informações para um diagnóstico mais eficaz na prevenção e detecção de falhas/defeitos, identificando suas causas em tempo real, o que, consequentemente, auxilia no aumento da produtividade/resultados da organização, evitando desperdícios de matéria-prima, insumos, produtos, entre outros.

Assessment of the resistance of monolithic reinforced concrete bearing systems to progressive collapse based on the principle of the level of permissible damage
Authors: Mitrovic Bozidar
Published: July 2021

The paper presents a method of using the reduction factor to ensure the stability of monolithic reinforced concrete bearing structures to progressive collapse.

Studies have established the values of the reduction factor based on the accepted value of the relative deformation corresponding to the formation of an admissible zone of "destruction" of the support section of the overlap under the action of transverse forces, as the main criterion for asessing the stress-strain state of monolithic reinforced concrete structures for the failure mode of a vertical supporting structure.

The accepted deformation criteria for a special limiting state correctly reflect the conditions for the formation of an admissible amount of damage to elements of bearing reinforced concrete systems.

The reduction factor (K1) obtained in the framework of the research performed is the most important deformation characteristic of the special limiting state of monolithic reinforced concrete bearing systems of buildings and structures for an emergency design situation associated with the failure of a local structural element.

Pyrolysis is an effective way to process waste of the pulp and paper industry, in particular, sludge-lignin, which makes it possible to obtain a commercial product – a carbon adsorbent. The method of thermochemical activation using sodium and potassium hydroxides is now widely used in pyrolysis of wood waste processing. This method enables the production of carbon nanostructured materials with high adsorption properties, especially when adsorbed from the liquid phase. The paper studies the influence of conditions for the synthesis of carbon adsorbents of sludge-lignin on their adsorption properties using sodium hydroxide as an activating agent. Sludge-lignin was obtained under laboratory conditions by treating lignin-containing wastewater with aluminum oxychloride coagulant. We applied the method of the planned experiment: a rotatable central composite design of the second order for three factors. We studied the influence of the main factors determining the adsorption properties of coals, namely, temperature, pyrolysis duration and sodium hydroxide dosage, on the values of output parameters characterizing the adsorption efficiency from the liquid phase, i.e. the iodine number and the adsorption capacity of methylene blue removal. We obtained experimental data, which were used to construct response surfaces illustrating the influence of the experimental factors on the output parameters. The positive effect of pyrolysis temperature and alkali dosage on the adsorption properties of the synthesized coals was found. The following results were obtained: the adsorption activity for iodine – 300 %, for methylene blue – 1000 mg/g; indicating a developed micro- and mesoporous surface and the possibility of using these compounds for adsorption of both gases and vapors, and organic substances from solutions. Therefore, samples of activated carbons synthesized from sludge-lignin were tested as lignin adsorbents of lignin-containing wastewater. The obtained dependences correlate well with the data describing the influence of pyrolysis parameters on the coal adsorption capacity of methylene blue removal. The high efficiency of adsorbents of sludge-lignin in the removal of lignin from solutions was shown. The value of the specific adsorption was about 1500 mg/g.

The XXV World Congress of the International Union of Forest Research Organizations (IUFRO) was held in Curitiba (Brazil) from September 25 to October 5, 2019. Representatives (2725 people) of forest academic, university and sector science, forestry business, and forestry governmental and non-governmental organizations from 96 countries attended the Congress and made over 2600 reports and presentations. For the first ever time this Congress was held in South America. The Congress motto “Forest Research and Cooperation for Sustainable Development” highlighted the broad subject of the Congress and showed the results of the five major directions of the IUFRO Strategy 2015–2019. The work of the Congress began with general events, including Tree Planting Ceremony, Congress Opening Ceremony, and Welcome Reception for all participants. Plenary Sessions, Technical Sessions, Thematic Discussions, Lectures and Presentations, and Poster Sessions were held according to the Official Program. Professional Excursions, namely Technical Tours and Thematic Exhibitions of products, technologies and services needed and available for the forest sector and forest research were provided. During the Congress, numerous IUFRO awards were delivered to the laureates, including the IUFRO Scientific Achievement Award, Distinguished Service Award, IUFRO Best Poster Award, as well as awards for students. Among the most important decisions of the XXV IUFRO World Congress are the following: Stockholm was selected as the next venue for the XXVI IUFRO World Congress in 2024; Dr. John Parrotta (USA) was elected President of IUFRO (2019– 2024); Professor Daniela Kleinschmit (Germany) and Professor Shirong Liu (China) were elected IUFRO Vice Presidents. The representative of our country Olga Shaitarova from the Saint-Petersburg State Forest Technical University named after S.M. Kirov became a member of the Board. Only eight participants from our country attended the Congress that confirms the insufficient level of financing of forest science in our country. Nevertheless, there is undoubtedly a significant prospect for the participation of Russian scientists in subsequent congresses and the activity within the IUFRO framework in general.

Seed quality and seed germination are the major indicators determining the success of regeneration and structure in natural forest ecosystems. This study focuses on problems associated with seed quality and seed germination under air pollution impacts in the surrounding forest ecosystems of Ulaanbaatar city of Mongolia. The objectives were to test whether there was any negative effect of air pollutants on the site index, and to analyze the relationship between seed quality and distance from the city center (maximum pollution). The study was carried out in natural larch forests (Larix sibirica Ledeb.) growing in the vicinity of the capital of Mongolia. A total of eight 100×100 m (1 ha) sample plots were laid out using completely randomized sampling design along the main wind direction. Remoteness from the city center was 10, 15, 20 and 30 km both to the north and to the south. Results showed a high variation in stand mean height (p > 0.001) and diameter (p > 0.001) among selected forest areas. In general, all sampled forests belonged to bonitet / quality classes III, IV and V, which are considered as relatively poor growing conditions in terms of site index. Therefore, greater site index and seed quality were observed in the most distant locations from the city center, and contrary, the poorest seed quality was detected in locations close to the city center. This emphasizes that forests growing close to pollution sources exist with a potential risk of degradation, and their reproductive organs are more sensitive to the effects of pollutants.
Stimulation of the Social Brain Improves Perspective Selection in Older Adults: A HD-tDCS Study

There is evidence for dissociable, causal roles for two key social brain regions in young adults. Specifically, the right temporoparietal junction (rTPJ) is associated with embodied perspective taking, whereas the dorsomedial prefrontal cortex (dmPFC) is associated with the integration of social information. However, it is unknown whether these causal brain-behaviour associations are evident in older adults. Fifty-two healthy older adults were stratified to receive either rTPJ or dmPFC anodal high-definition transcranial direct current stimulation in a sham-controlled, double-blinded, repeated-measures design. Self-other processing was assessed across implicit and explicit level one (line-of-sight) and level two (embodied rotation) visual perspective taking (VPT) tasks, and self-other encoding effects on episodic memory. Both rTPJ and dmPFC stimulation reduced the influence of the alternate perspective during level one VPT, indexed by a reduced congruency effect (difference between congruent and incongruent perspectives). There were no stimulation effects on level two perspective taking nor self-other encoding effects on episodic memory. Stimulation to the rTPJ and dmPFC improved perspective selection during level one perspective taking. However, dissociable effects on self-other processing, previously observed in young adults, were not identified in older adults. The results provide causal evidence for age-related changes in social brain function that requires further scrutinization.

Sexual objectification – perceiving or treating a woman as a sexual object – is a widespread phenomenon. Studies on sexual objectification and its consequences have grown dramatically over the last decades covering multiple and diverse areas of research. However, research studying sexual objectification might have limited internal and external validity due to the lack of a controlled and standardized picture database. Moreover, there is a need to extend this research to other fields including the study of emotions. Therefore, in this paper we introduce the SOBEM Database, a free tool consisting of 280 high-resolution pictures depicting objectified and non-objectified female models expressing a neutral face and three different emotions (happiness, anger, and sadness) with different intensity. We report the validation of this dataset by analyzing results of 134 participants judging pictures on the six basic emotions and on a range of social judgments related to sexual objectification. Results showed how the SOBEM can constitute an appropriate instrument to study both sexual objectification per se and its relation with emotions. This database could therefore become an important instrument able to improve the experimental control in future studies on sexual objectification and to create new links with different fields of research.
Hackear la línea abismal.

El objetivo del presente ensayo es analizar, a través de algunas practicas artísticas descolonizadoras, la cara social, epistémica y colonial que acompaña la crisis climática y el Capitaloceno. Para lograrlo, se decide adoptar y utilizar algunos conceptos de la filosofía de la tecnología de Bernard Stiegler, articulándolos con nociones, posturas y perspectivas del pensamiento descolonial y en particular con el “epistemicidio”, la “línea abismal” y la ecología de los saberes de Boaventura de Sousa Santos. Las obras artísticas de Cristian Villavicencio, Jaime Del Val y Fredy Vallejos posibilitan este acercamiento entre crítica farmacológica (Stiegler) y ecología de los saberes, encarnando la función de dispositivos estéticos y socioepistémicos anclados a los devenires tecnológicos en las artes, capaces de desarrollar una farmacología de lo digital en clave descolonial.

Este trabajo retoma aportes teóricos de tres autoras latinoamericanas –el problema de la forma según Nora Catelli, la crítica cultural según Nelly Richard y los confines de la figuración según Ana Amado– que permiten iluminar algunas coordenadas plausibles para enfocar desde perspectivas feministas ciertas cuestiones teóricas acerca de los estudios comparativos de los cines de América Latina. Para eso, se tienen en cuenta aspectos estéticos, diferencias culturales y asimetrías sociales que atraviesan la circulación de paradigmas de investigación en el campo académico internacional.
God Bless America (2019)

El cristianismo tiene una importante presencia cultural en los Estados Unidos de América. Las diferentes comunidades cristianas están muy fragmentadas y son muy variopintas, de entre todas esas comunidades destaca el protestantismo reformado. El documental, mediante la grabación de entrevistas y contextos socio-culturales, proyecta una imagen bastante innovadora e inédita de los protestantes reformados, también conocidos como baptistas y evangelistas. Los mensajes morales y los preceptos doctrinales, que se reproducen en el documental, muestran de forma esquemática un estilo de vida basado en el tradicionalismo, que trasciende más allá de las fronteras estadounidenses. También se refleja la capacidad de regeneración dialéctica y de reconversión tecnológica que tienen este tipo de comunidades cristianas a la hora de enfrentarse a las nuevas situaciones políticas e institucionales.
