Authors: Пашков А.В. , Гелюх П.А.
Published: June 2022

Рассматриваются колебания плиты, лежащей на упругом основании, от действия инерционных сил вращающейся неуравновешенной массы. Плита предполагается абсолютно жесткой, модель упругого основания – винклеровская. Неуравновешенность представлена в виде точечной массы, смещенной относительно оси вращения ротора.Кроме вертикальной горизонтальной и вертикальной составляющих силы инерции учтен также инерционный момент, который вызывает крутильные колебания плиты. Таким образом, рассматриваются колебания системы с тремя степенями свободы. Дифференциальные уравнения колебаний получены на основании уравнений Лагранжа второго рода. Получены их решения.

Vibrations of a plate lying on an elastic base from the action of inertial forces of a rotating unbalanced mass are considered. The plate is assumed to be absolutely rigid, the elastic base model is Winkler. Unbalance is represented as a point mass displaced relative to the axis of rotation of the rotor.In addition to the vertical horizontal and vertical components of the inertia force, the inertial moment, which causes vibrations of the plate, is also taken into account. Thus, the oscillations of a system with three degrees of freedom are considered. The differential equations of oscillations are obtained on the basis of Lagrange equations of the second kind. Their solutions are obtained.

BODIPY-labelled estrogens for fluorescence analysis of environmental microbial degradation
Authors: Felion Celeste , Lopez-Gonzalez Ricardo , Sewell Alan L. , Marquez Rodolfo , Gauchotte-Lindsay Caroline
Published: June 2022

Biodegradation of estrogen hormone micropollutants is a pervasive approach towards their remediation. Fluorescently labelled substrates are used extensively for rapid, near real-time analysis of biological processes and are a potential tool for studying biodegradation processes faster and more efficiently than conventional approaches. However, it is important to understand how the fluorescently tagged surrogates compare with the natural substrate in terms of chemical analysis and the intended application. We derivatized three natural estrogens with BODIPY fluorophores by azide-alkyne cycloaddition click reaction and developed an analytical workflow based on simple liquid-liquid extraction and HPLC-PDA analysis. The developed methods allow for concurrent analysis of both fluorescent and natural estrogens with comparable recovery, accuracy, and precision. We then evaluated the suitability of BODIPY-labelled estrogens as surrogate substrates for studying biodegradation using a model bacterium for estrogen metabolism. In service of this objective, the developed analytical methods were successfully employed to assess the biological transformation of 17β-estradiol, with and without BODIPY fluorescent tag.

Published: June 2022

Natural ligand-receptor interactions that play pivotal roles in biological events are ideal models for design and assembly of artificial recognition molecules. Herein, aiming at the structural characteristics of the spike trimer and infection mechanism of SARS-CoV-2, we have designed a DNA framework-guided spatial patterned neutralizing aptamer trimer for SARS-CoV-2 neutralization. The ~5.8 nm tetrahedral DNA framework affords precise spatial organization and matched valence as four neutralizing aptamers (MATCH-4), which matches with nanometer precision the topmost surface of SARS-CoV-2 spike trimer, enhancing the interaction between MATCH-4 and spike trimer. Moreover, the DNA framework provides a dimensionally com-plementary nanoscale barrier to prevent the spike trimer-ACE2 interaction and the conformational transition, thereby inhibiting SARS-CoV-2-host cell fusion and infection. As a result, the spatial and valence-matched MATCH-4 ensures improved binding affinity and neutralizing activity against SARS-CoV-2 and its varied mutant strains, particularly current Omicron variant that are evasive of the majority of existing neutralizing antibodies. In addition, because neutralizing aptamers specific to other targets can be evolved and assembled, the present design has the potential to inhibit other wide-range and emerging pathogens.

Sobre la pastorada aragonesa. Estudio filológico de las pastoradas en aragonés del siglo XVIII
Authors: Benítez María Pilar , Latas Oscar
Published: June 2022

Sobre la pastorada aragonesa. Estudio filológico de las pastoradas en aragonés del siglo xviii es una investigación que intenta poner de relieve el valor filológico de las pastoradas aragonesas, en general, y de las escritas en aragonés, en particular. Asimismo, quiere responder a las cuestiones literarias y lingüísticas que suscitan estas piezas teatrales, desde planteamientos que se alejan de la visión tradicional sobre dichas obras y sobre la lengua utilizada en ellas. Así, desde el punto de vista literario, se defiende que la pastorada aragonesa, si bien suele estudiarse dentro del llamado dance aragonés, constituye un subgénero teatral autónomo, que presenta características diferentes, pero también similares, a manifestaciones dramáticas de otros territorios. Desde el punto de vista lingüístico, se sostiene que la lengua empleada en estos textos dramáticos corresponde a la hablada en cada una de las localidades en las que se representaron. Las pastoradas son, por tanto, además del mayor corpus escrito en aragonés en los siglos xviii y xix, un interesante e ineludible testimonio para comprender la evolución de dicha lengua.
Nostalgia for a Lost Home: Exile and Trauma in Lucette Lagnado’s Memoirs
Authors: Issaoui Ichrak , Issaoui Ilhem
Published: June 2022

This paper seeks to study exile as a traumatic experience by focusing on the multiple manifestations of trauma in the memoirs of the Jewish-Egyptian writer Lucette Lagnado. Exile, in Edward Said’s view, “is the unhealable rift forced between a human being and a native place, between the self and its true home” (Said 2000: 173). Lagnado chose writing to voice the trauma of exile of the whole Jewish Egyptian community expelled from Egypt after the establishment of the state of Israel and the arrival of the Free Officers to power in 1952. In Lagnado’s memoirs, trauma re-surfaces in different places and times, through flashbacks and nightmares. These unwanted and suppressed memories reemerge involuntarily and keep Lagnado trapped in an ever-ending nostalgia. Both Caruth’s work on trauma and Herman’s analysis of the three stages of trauma recovery will help us better understand the place of trauma in Lagnado’s memoirs.
Whatever is Inside is Outside: Do Nostalgic Memories Exist in Parallel Universes?
Authors: K Samhita
Published: June 2022

This paper explores nostalgic memories from an unconventional perspective and their complex relationship with parallel universes. The arrow of time is not necessarily linear, and nostalgic memories pertaining to the past or the future, be it in this world or in parallel universes, could be accessed in various states of consciousness. Whatever is inside (in the internal environment of an individual) is outside (in the external environment), which is in line with esoteric teachings and individualistic experiences. The Indian concept of Maya (illusion) that applies to the material world, acts as a hindrance to experiencing Brahman or the ultimate Truth. Until one is able to perceive the infinitely connected universe in all its gigantic underlying unity, it may be posited that nostalgic memories exist in parallel universes.
STUDY OF SINGLE-PHASE EARTH FAULT IN ELECTRICAL NETWORKS OF 6-35 KV WITH AN ISOLATED NEUTRAL
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, SBITNEV EVGENIY A. , OSOKIN VLADIMIR L.
Published: June 2022

Ground faults in networks with an isolated neutral are not switched off by relay line protections due to low capacitive currents. It is recommended to disconnect the line with a earth fault as quickly as possible, but sometimes it is difficult to find and localize the damage. To analyze the emergency mode of single-phase ground fault in networks with an isolated neutral, the phase coordinate method for calculating phase voltages is used. At the point of damage, the values of the phase-to-phase voltages remain unchanged, and the phase voltages change. Real research and analysis of electrical network modes of 6-35 kV with an isolated neutral is rather time-consuming task. Therefore, the calculation of phase voltages at the substation during an earth fault is carried out through the transition resistance on the line based on the phase coordinate method. The authors developed a virtual model of studied power transmission line for analyzing asymmetric modes of three-phase networks and checking the operability of the method in the MATLAB Simulink simulation package. The simulation results showed that there was no discrepancy between the voltage and current values of the original model in phase coordinates and the Simulink model. As a result of the research, the authors have found that the phase coordinate method helps calculate emergency modes with the overlay of several component accidents taking into account load currents. The model in phase coordinates will allow analyzing relay protection operation at high speed under different operating modes of the electric power system.
SIMULATING RATIONAL MODES OF ELECTRIC ACTIVATOR FOR ROUGH FORAGE PROCESSING
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, STORCHEVOY VLADIMIR F.
Published: June 2022

The high productivity of farm animals requires that the feeding ration should contain all the necessary nutrients to meet their needs. Before offering to animals, feeds are subjected to additional processing to increase their nutritional value and palatability A promising method is the treatment of roughage with activated media. The authors designed and described the operating principle of a single-phase flow-type electric activator with a belting-type diaphragm. It has optimal parameters to prepare the required amount of activated water (catholyte) for processing roughages in the amount of five tons per season. To justify the operating modes of the electric activator, a matrix of active planning of a three-factor experiment was used. When choosing the intervals for changing factors (the electric activator power, performance, and cycle), the authors were guided by the technological conditions of electrochemical activation of the liquid and the activator design features. The efficiency of the liquid activation process was determined by the value of change in the hydrogen index of the activated solution, the voltage loss on the electric activator, and the current density. Regression models were obtained to optimize the operating modes of the activator. Based on the equations obtained, it is possible to change the variable parameters to obtain the desired proportions of the input and output parameters of the installation.
Transparenz. Herausforderung für Demokratie und Privatheit
Authors: Watzinger Lea
Published: June 2022

Seit der Jahrtausendwende entwickelt der Transparenzbegriff eine zivilgesellschaftliche und politische Eigendynamik. Transparenz entwickelt sich zur Ideologie einer zeitgemäßen digitalen Medienlogik. Als zukunftsweisende und Freiheit versprechende Norm steht sie auf den Agenden von Demokratie-AktivistInnen, PolitikerInnen, InternetnutzerInnen, aber auch der demokratischen Gesellschaft als ganzer. Der gläserne Mensch allerdings unterstützt durch sein Nutzungsverhalten im Digitalen seine eigene Transparenz. Dies resultiert meist nicht in Freiheit und Partizipation, sondern in Kontrolle und Manipulation. Transparenz ist zu einem Konsensbegriff von beinahe universaler Geltung avanciert und leistet einen wesentlichen Beitrag zur Selbstverständigung von Gesellschaften im digitalen Transformationsprozess. Dabei gerät oft in den Hintergrund, dass es sich, je nachdem, wer oder was transparent sein soll, um völlig verschiedene Bezugspunkte handelt. Lea Watzinger geht der Diskussion um Transparenz unter Rückgriff auf philosophiegeschichtliche Vorgängerdebatten zu »Öffentlichkeit« und »Publizität« nach und sortiert das Begriffsfeld von »Transparenz« neu.

The Strategies and Policies for Consolidation of the Liberal Democracy in Poland since 2005: Focusing on the Governments of PiS and PO
Authors:   Institute of East and West Studies Yonsei University, Kim Kyung-Mi
Published: June 2022

This paper analyzes the consolidation of liberal democracy in Poland after 2005 based on the system transition stage theory. The nine indicators are selected for it: the guarantee of basic rights, the separation of powers, the government changes by elections, the existence of non-official power groups, the stabilization of the political party system, the operation of the market, the guarantee of private property rights, economic development, the development of civil society, the spread of democratic political culture, and a fair free media. Since PiS took power in 2015, the independence of the judiciary has been greatly threatened through reforms to the constitutional order. The basic rights guaranteed in the constitution were also limited by the enactment and revision of the Police Act, the Anti-Terrorism Act, and the Assembly Act. The changes of government through elections have been successfully implemented since the system transition in 1989, but the party system has not been stabilized due to the merger and division between parties. Almost all economic indicators in the economic sphere show that Poland has succeeded in its transition to the market economy system. Polish civil society has gradually increased its power. PiS is increasing its control over the media through the amendments of related laws. Overall, during the PiS rule, the consolidation of liberal democracy is regressing.

O debate ambiental e a construção de um conhecimento: paradigma moderno em questão
Authors: Priori Josimar
Published: June 2022

O objetivo deste trabalho consiste em analisar como o debate ambiental tem produzido um novo tipo de conhecimento. Argumentamos que tal movimento cria um conjunto de categorias por meios das quais o mundo passa a ser representado, explicado e modificado. A metodologia utilizada para a realização deste artigo foi a pesquisa bibliográfica. Após análise crítica dos textos, selecionamos e analisamos os que se mostraram referências relevantes na construção do saber ambiental. Inicialmente demonstramos que este saber parte da constatação de um conjunto de crises, as quais se entrelaçam e se associam ao paradigma moderno, o qual oferece termos para a separação do homem e da natureza, investindo o primeiro na posição de senhor, dominador e explorador e segunda com objeto de exploração. O saber ambiental questionara várias das premissas modernas, entre os quais se destaca a redução da razão à sua função técnico-instrumental, os limites de um conhecimento mecanicista e linear e a ilusão de crescimento econômico ilimitado. Por fim, analisamos as bases do saber ecológico, o qual toma como justificativa a ideia de crise, se coloca como alternativa ao paradigma moderno e apresenta como premissa principal a produção de um saber capaz de compreender os fenômenos sociais, políticos, econômicos, biológicos e ambientais em suas relações.

Authors: Shafwan Muhammad Hambal
Published: June 2022

Wasathiyah Islam is Islam that is rahmatan lil 'alamin, not Islam such as the understanding of extremists who tend to put forward a hard attitude without compromise (ifrâth), or the understanding of liberal groups who often interpret religious teachings very loosely, freely, even almost leaving the line of religious truth. tafrîth). This article aims to explore the prophetic hadiths which are the basis for being moderate in Islam, both in aqidah, worship, and muamalah. This will result in a complete understanding of true religious moderation. This research is a qualitative research through literature study. The method used in the research is the thematic method, by collecting hadith and correlating it with the object of research. The results of the study indicate that there are several hadiths that prohibit Muslims from being extreme in religion, both in aqidah, worship, and muamalah with others. Sahih hadiths that exist invite to understand and practice religion must go through the path of balance and be in the middle way so that religion seems friendly, gentle and affectionate. The principle of moderation in religion (wasathiyah) described in the nabawi hadith is the principle of al-khairiyah (being the best), al-tawazun (balance), raf'u al-haraj (removing difficulties), al-'is (being fair), and al-tasamuh (tolerant). Islam wasathiyah adalah islam yang rahmatan lil ‘alamin, bukan Islam seperti pemahaman para ekstremis yang cenderung mengedepankan sikap keras tanpa kompromi (ifrâth), atau pemahaman kelompok liberalis yang sering menginterpretasikan ajaran agama dengan sangat longgar, bebas, bahkan nyaris meninggalkan garis kebenaran agama sekalipun (tafrîth). Artikel ini bertujuan untuk menggali hadits-hadits nabawi yang menjadi dasar untuk bersikap moderat dalam beragama Islam, baik dalam beraqidah, beribadah, dan bermuamalah. Sehingga akan menghasilkan pemahaman yang utuh tentang moderasi beragama yang sesungguhnya. Penelitian ini merupakan penelitian kualitatif melalui studi pustaka. Metode yang digunakan dalam penelitian adalah metode tematik, dengan cara pengumpulan hadis dan mengorelasikan dengan objek penelitian. Hasil penelitian menunjukkan bahwa terdapat beberapa hadis yang melarang umat Islam untuk bersikap ekstrim dalam beragama baik dalam beraqidah, beribadah, dan bermuamalah dengan sesama. Hadits-hadits shahih yang ada mengajak untuk memahami dan mengamalkan agama harus melalui jalur keseimbangan dan berada di jalan tengah sehingga agama terkesan ramah, lembut dan kasih sayang. Prinsip moderasi dalam beragama (wasathiyah) yang diterangkan dalam hadis nabawi adalah prinsip al-khairiyah (menjadi yang terbaik), al-tawazun (keseimbangan), raf’u al-haraj (menghilangkan kesulitan), al-‘adalah (bersikap adil), dan al-tasamuh (toleran).
Proposal for a new housing model for the inland areas regeneration. The BioVillage 4.0
Authors: D'Andria Emanuela , Fiore Pierfrancesco , Sicignano Enrico
Published: June 2022

In addition to cities and metropolises, the European territory is made up of many small settlements, custodians of a vast material and immaterial heritage, very often of great historical, cultural and environmental value. In recent decades, these realities have undergone a significant demographic decline induced by the new requirements of contemporary life: the lack of job opportunities, inadequate infrastructure, and poor essential services have encouraged the population to move to the cities, starting a process of social, cultural and economic marginalisation of rural areas. However, the current environmental crisis and the problems of urban densification are encouraging the birth of a ‘new perspective’ that considers the enhancement of inland areas and small towns as a possible driver for the sustainable development of territories and the definition of a new city-countryside relationship. Therefore, recovering inland areas is becoming an increasingly important necessity, which is leading to the drafting of many plans and interventions aimed at reversing the demographic decline trend. Among the most representative projects, two European strategies are based on the Ecovillage and Smart Villages models. Both models emphasise the role of local communities in deciding what action should be carried out to valorise small towns. However, the modalities and nature of the interventions and their methodological approach are substantially different.
In view of the above, and starting from the analysis of some emblematic case studies, the paper investigates the peculiarities of the Ecovillage and Smart Villages models, with the aim of highlighting their main criticalities and potentials. From the comparison between the two strategies, a new model for the recovery and valorisation of small towns is proposed, which is called BioVillage 4.0.
