Published: November 2023

This paper describes the method of determining reasonable test levels for product of spacecraft with big size, low mass and high test levels when the force of the shaker facilities is limited. The major step is to compute the test envelope from both Newton’s law and Ampere’s force aspects, the minimum of which is defined as the final safety control envelope for flight spacecraft hardware. By using this method, the shaker facilities can provide maximum force for spacecraft experiencing effective assessment and the interruptions can be avoid during the process of test operation.
The effect of ambient temperature on the internal ballistic overload of a large-caliber artillery projectile fuze system
Authors: Yang Zilong , Kong Deren , Zhang Chunyan
Published: November 2023

The change of ambient temperature will cause the change of gunpowder burning rate, which will directly affect the ballistic performance of the projectile and cause the change of the overload of the projectile fuze system. In this study, the numerical simulation program of the interior trajectory of a large-caliber gun was established by MATLAB, and the variation rules of the corresponding trajectory parameters at different temperatures were obtained. ANSYS finite element software is used to analyze the force of the projectile fuze system under different ambient temperatures. The results show that under the same loading conditions, with the increase of ambient temperature, the maximum pressure in the gun bore and the muzzle velocity of the projectile increase significantly, and the stress and strain of the projectile fuze system in the bore increase gradually. The numerical simulation results are in good agreement with the theory, which reveals the influence of ambient temperature on the overload in the bore of the projectile fuze system to a certain extent, and provides theoretical support for the study of internal ballistics, charge design and gun use.
Study on the performance of gravel stabilization by red mud-based cementitious materials
Authors: Zhang Huiqin , Ji Ping , Wu Si
Published: November 2023

In this paper, red mud and slag were used as the main cementitious materials, and desulfurization gypsum and exciter materials were mixed to prepare red mud-based cementitious materials with excellent performance. The mechanical properties of red mud-based cementitious material stabilized gravel material were investigated by carrying out the compaction test, unconfined compressive strength test, splitting strength test and fatigue performance test. The test results show that with the increase in the dose of cementitious material, the hydration is more significant, generating more hydrated calcium silicate (C-S-H) gel, which in turn makes the unconfined compressive strength and splitting strength increase to a certain extent. Adding exciter and desulfurization gypsum in the appropriate amount is conducive to improving the hydration of red mud, improving the structural compactness, and improving the mechanical properties, volumetric stability and seepage resistance of the cementitious material.
Anti-deformation performance of asphalt modified by carbon black extracted from waste cooking oil pyrolysis waste tires rubber
Authors: Li Yiling , Qin Yankai
Published: November 2023

As a promising renewable resource, waste tire rubber powder has been utilized to enhance asphalt performance but it has compatibility concerns with matrix asphalt. To solve the phase separation between crumb tire rubber (CTR) and asphalt, waste cooking oil (WCO) has been successfully employed as the solvent to desulfurize crumb rubber. However, about 30 % of carbon black is wrapped in crumb rubber, which has a high recycling value. The cross-linking network structure of the crumb rubber can be loosened by waste cooking oil, and the carbon black will gradually peel off. This study desulfurizes crumb rubber with waste cooking oil at 180 ℃, and the carbon black produced by the evolution of rubber structure was separated by Soxhlet extraction. The rubber-cracked carbon black (RCCB) and the industrial carbon black N330 were added to asphalt, and the impact of the two different carbon black on the anti-deformation of asphalt was analyzed by dynamic shear rheometer (DSR). The results indicated that at the same dosage of 5 %, the carbon black separated from rubber will weaken the deformation resistance of asphalt at high temperatures, rather than improving it like N330 produced in the industry.
Permanent displacement estimation method based on variational mode decomposition
Authors: Xu Xiaoquan , Dong Yinfeng , Fang Dezhi , Li Dong
Published: November 2023

In the near-field area of strong earthquakes, the information recorded by a strong seismometer includes ground motion information and complex low-frequency noise. This noise results in the presence of an “extra” acceleration component in the record that is independent of ground motion, and these components are integrated into the velocity and displacement time history to cause offset. In order to solve this problem, this paper adopts a baseline correction method based on variational mode decomposition (VMD), which decomposes seismic signals into modal functions of different frequencies and then extracts the low-frequency modal functions. It is worth noting that these low-frequency modal function components contain linear trend terms, a property that allows us to perform baseline corrections efficiently. The results show that the permanent displacement obtained by this method is in good agreement with the coseismic displacement observed by GPS stations nearby. This method provides an efficient approach for estimation permanent displacement which helps revealing the focal mechanism of an earthquake.
Application of computer simulation technology in modal analysis of engine mount
Authors: Yun Yuping
Published: November 2023

In order to obtain the vibration response characteristics of the engine mount, its constrained modal analysis was completed based on the finite element method. The mesh of the contact part between the bolt head and the bracket part was considered as shared node, achieving the simulation of compressive contact between the bolt and bracket parts. The simulation results of natural frequencies and modal shape were verified through constrained modal experiments. The results indicated that the accuracy of the simulation results is high, and the maximum deviation between the natural frequency and the experimental value is less than 5 %. Compared to higher-order modes, the preload had a more significant impact on lower order modes. Based on the modal analysis results, reasonable excitation vibration directions were set, and the dynamic stiffness of the model was simulated and tested within the frequency range of 2400 Hz, providing important basis for optimizing vibration isolation performance.
Analysis of the effect of maneuvering overload on the reaction force of the main shaft bearing in aero-engine
Authors: Jiang Zhenhe , Chen Moli , Luo Guihuo , Wang Weiying
Published: November 2023

In order to study the effects of maneuvering overload on the main shaft bearing (abbreviation: bearing) reaction force in an aero-engine, a bending-torsion coupling dynamic model of the dual rotor system under maneuvering overload was established. Combined with the output parameters of the system model, the bearing reaction force analysis model was established. The maneuvering overload parameters are input into system model. Newmark-β and Newton-raphson methods are used to obtain the bearing reaction force response, and the change laws of bearing reaction force under the different maneuvering overloads are analyzed. The results show that gravity will make the transient response of bearing reaction force offset, and maneuvering overload will make the offset shift. Maneuvering overload will cause bearing to produce a circumferential asymmetric reaction force. For bearing 1, the additional gyroscopic torque in maneuvering overload has a significant effect on the dynamic eccentricity, resulting in a larger offset of reaction force of y direction. For bearings 3 and 4, reaction force of x direction has a larger offset. Under the influence of bent-torsional coupling, the combined frequencies of base frequencies of rotational speed appear in the reaction force spectrum diagram.

Authors: Zhang Xingyu , Dong Yinfeng , Wei Lejun , Guo Feiyu , Su Qingshuang
Published: November 2023

Assessing the nonlinearity of a site plays a crucial role in earthquake engineering. For some building structures and lifeline projects that need safety assessment after earthquakes, the analysis of nonlinear degree of sites can help accurately revealing the amplification effect of sites and evaluating the damage degree of buildings which is convenient for subsequent reinforcement and demolition work. The quantitation of nonlinear threshold of sites is an important method to evaluate the degree of site nonlinearity. In this paper, a nonlinear characteristic index reflecting the degradation of shear modulus is proposed based on the instantaneous frequency of the site calculated by using the vector auto-regression moving average (VARMA) model. Then, seismic records of class Ⅰ, Ⅱ, Ⅲ and Ⅳ sites specified as per code for seismic design of buildings in China are selected from the KiK-net network in Japan, and the threshold value of ground motion acceleration characterizing the nonlinear response of sites are provided. Finally, the variation of the nonlinear characteristic index (shear modulus degradation) vs. different (peak ground acceleration) PGA for four types of sites are presented.
Optimization of vane pump structure based on modal characteristic analysis
Authors: Chi Jinping
Published: November 2023

In order to ensure the good stability and reliability of the vane pump, the modal characteristics of the mechanical structure were studied and analyzed through finite element simulation and impact modal testing. Based on the stiffness criterion, an optimization plan was proposed for the structure of the vane pump without reducing the natural frequency. Adopting tetrahedral adaptive mesh method, the mesh quality of the modal simulation model was verified to ensure the accuracy and efficiency of the calculation. In modal testing, force sensors and acceleration sensors were arranged reasonably. The excitation signal would be transmitted to the integrated vibration testing system for processing, and modal analysis and processing would be carried out through LMS Test Lab. Based on curve fitting, the spectrum and modal parameters of the tested structure could be obtained. The influence of different curvature radius of cover plates on natural frequencies were studied, and the results show that increasing the curvature radius within a certain range can enhance stiffness and improve processability.
Study on the vibration characteristics of deep groove ball bearings under time-varying loads
Authors: Han Zeguang , Chen Xiaofei , Hao Ruiqin , Liu Facai , Li Jiaqi
Published: November 2023

A general methodology for dynamic modeling and analysis of deep groove ball bearing used in the crank-slider mechanism of punching machine is presented in this paper. The time-varying loads applied at the inner ring of this bearing can be obtained by analyzing the planar multibody systems. The bearing joint has been modeled by introducing a nonlinear constraint force system, which takes into account the contact stiffness interaction between the rolling elements and the raceways. The four-degree-of-freedom dynamic equations for the inner and outer rings of the bearings is established by Newton's second law. By numerical calculation, the variations of the load, trajectory, FFT frequency domain response, and x direction phase trajectory and Poincare of the inner ring, and the contact force on each ball element are discussed. The results indicate that the present methodology can not only be used to analyze the overall dynamic behavior of crank-slider mechanism and the deep groove ball bearing used in punching machine, but also to obtain the dynamic loads of the inner ring and ball in bearing. Therefore, the dynamic loads on ball elements can provide a basis for the strength checking, fatigue life calculation and wear analysis of the deep groove ball bearing.
Acceleration spikes in strong earthquake ground motion induced by dilatancy cyclic mobility mechanism
Authors: Su Qingshuang , Dong Yinfeng , Guo Feiyu , Zhang Xingyu
Published: November 2023

Strong motion records with acceleration spikes have occurred frequently in recent major earthquakes, acceleration spikes contribute to the peak ground accelerations (PGAs) and the amplitudes are significantly higher than the predicted values based on present attenuation relation. The generation mechanism of acceleration spikes is revealed based on long-term monitoring after the 2008 Mw 8.0 Wenchuan earthquake. The horizontal accelerogram with obvious spikes from the Mw 9.0 Tohoku-Oki earthquake is reproduced by using numerical simulation, and it’s found that the dilatancy cyclic mobility (DCM) mechanism can explain the generation of acceleration spikes. The support vector machine (SVM) is used to efficiently identify DCM sites. We found that the spatial distribution of DCM sites is parallel to the earthquake source fault and the corresponding PGAs of ground motions recorded in DCM sites differ significantly from those recorded in non-dilatancy cyclic mobility (NDCM) sites.
Gender Aspect and Contradictions in Managing Women’s Career
Authors: Borisova N. A.
Published: November 2023

The article focuses on the rising trend of women holding top positions in different sectors of economy. A serious contribution to this trend was made by government that took a strategic decision about reducing the list of jobs and positions with harmful and/or dangerous labour conditions, where the use of women’s labour is restricted. However, apart from state policy, we should point out to the growing activity of women themselves, who do their best to build the career on a level with men. The article shows trends, which testify to the fact that women hold top positions more frequently today and, at the same time it provides factors that can hinder the development of women’s career. Estimating the impact of all these factors can foster more accurate career planning. According to the author, higher quality of career management could raise the degree of job satisfaction, in particular in women’s quarters. Another important argument in favor of the necessity to improve the quality of women’s career is dependence of labour productivity on the degree of female workers’ satisfaction. Realization of work effectiveness is a source of inspiration and motivation. With regard to the rising trend of retaining personnel, cutting turnover and certain deficit on labour market career management becomes a factor of higher company competitiveness, as it can affect both productivity and personnel turnover, which is essential because of the high share of women in the general structure of employable population in the Russian Federation.

The subject of the present article is researching the opportunities to use design-thinking for building the efficient ecosystem model of business. The goal of the research deals with the necessity to study three principle fields of shaping the ecosystem business-model of the company: customers, partners and products/services. We think that prototyping of this model of business organization shall be accomplished along these lines. The article analyzed the origin of the notion ‘design-thinking’ and studied features of shaping the ecosystem of business-model on the basis of design-thinking. The authors learnt the experience of shaping overseas and Russian models of ecosystem business and identified factors of its efficiency. According to our opinion, the use of ecosystem company approaches, which have been analyzed, is a key factor of successful business running in current conditions characterized by growing digitalization and changing of customer behavior patters from off-line to on-line deals. The mentioned customer behavior transformation has been observed in recent years however, the most impressive acceleration of transition to on-line ecosystems took place during COVID-19 pandemic and in the post-pandemic period. The authors are sure that the use of design-thinking, its methodological and instrumental approaches can give an opportunity to make integrated client-oriented offers and create new customer values, especially at the initial stages of developing ecosystem business-models. Effectiveness of using ecosystem business—models was analyzed by RUSECO index (weighted on market capitalization of home corporations), which demonstrated stable upward dynamics up to 2022. The information given by the authors about market capitalization of overseas ecosystem companies testifies in favor of the assumption of expediency of this approach to developing efficient business-models.

Artificial General Intelligence; Pragmatism or an Antithesis?

Published: November 2023

Artificial intelligence is promoted by means of incomprehensible advocacy
through business majors that cannot easily be equated with human consciousness and

numeric inferences. This paper reviews through centuries of evolved human
knowledge, and the resolutions as referred through the critics of mythology, literature,
imagination of celluloid, and technical work products, which are against the intellect of
both educative and fear mongering. Human metamorphic abilities are compared against
the possible machine takeover and scope of envisaged arguments across both the
worlds of ‘Artificial Intelligence’ and ‘Artificial General Intelligence’ with perpetual
integrations through ‘Deep Learning’ and ‘Machine Learning’, which are early
adaptive to ‘Artificial Narrow Intelligence’ — a cross examination of hypothetical
paranoid that is gripping humanity in modern history. The potentiality of a highly
sensitive humanoid and sanctification to complete consciousness at par may not be a
near probability, but social engineering through the early stages in life may indoctrinate
biological senses to a much lower level of ascendancy to Artificial Narrow Intelligence
— with furtherance in swindling advancement in processes may reach to a pseudo-Artificial Intelligence {i}. There are no convincing answers to the discoveries from
ancient scriptures about the consciousness of archetypal humans against an anticipated
replication of a fulfilling Artificial Intelligence {ii}. Human use of lexicon has been the
focal of automata for the past few years and the genesis for knowledge, and with the
divergence of languages and dialects, scores of dictionaries and tools that perform
bidirectional voice and text — contextual services are already influencing the lives, and
appeasement to selective humanly incidentals is widely sustainable today {iii}.
Synthesizing and harmonizing a pretentious labyrinthine gizmo is the center of human

A Big Data Analytics Architecture Framework for Oilseeds and Textile Industry Production and International Trade for Sub-Saharan Africa (SSA)
Authors: Kabanda Gabriel
Published: November 2023

Among the most revolutionary technologies are Big Data Analytics,
Artificial Intelligence (AI) and robotics, Machine Learning (ML), cybersecurity,
blockchain technology, and cloud computing. The research was focused on how to
create a Big Data Analytics Architecture Framework to increase production capability
and global trade for Sub-Saharan Africa's oilseeds and textile industries (SSA).
Legumes, shea butter, groundnuts, and soybeans are significant crops in Sub-Saharan
Africa (SSA) because they offer a range of advantages in terms of the economy,
society, and the environment. The infrastructure, e-commerce, and disruptive
technologies in the oilseeds and textile industries, as well as global e-commerce, all
demand large investments. The pragmatic worldview served as the foundation for the
Mixed Methods Research technique. This study employed a review of the literature,
document analysis, and focus groups. For the oilseeds and textile sectors in SSA, a Big
Data analytics architectural framework was created. It supports E-commerce and is
based on the Hadoop platform, which offers the analytical tools and computing power
needed to handle such massive data volumes. The low rate of return on investments
made in breeding, seed production, processing, and marketing limits the
competitiveness of the oil crop or legume seed markets.

Published: November 2023

The massive number of sensors deployed in IoT generates humongous
volumes of data for a broad range of applications such as smart home, smart healthcare,
smart manufacturing, smart transportation, smart grid, smart agriculture etc. Analyzing
such data in order to facilitate enhanced decision making and increase productivity and
accuracy is a critical process for businesses and life improving paradigm. Machine
Learning would play a vital role in creating smarter techniques to predict the intruder
from the dataset. It has shown remarkable results in different fields, including Network
security, image recognition, information retrieval, speech recognition, natural language
processing, indoor localization, physiological and psychological state detection, etc. In
this regard, intrusion detection is becoming a research focus in the field of information
security. In our experiment, we used the CICIDS2017 data set to predict the Network
Intruder. The Canadian Institute of Cyber Security released the data set CICIDS-2017,
which consists of eight separate files and includes five days’ worth of normal cum
abnormal network packet data. The goal of this research is to examine relevant and
significant elements of large network packets in order to increase network packet attack
detection accuracy and reduce execution time. We choose important and meaningful
features by applying Information Gain, ranking and grouping features based on little
weight values on the CICIDS-2017 dataset; and then use Random Forest (RF), Random
Tree (RT), Naive Bayes (NB), Bayes Net (BN), and J48 classifier algorithms. The
findings of the experiment reveal that the amount of relevant and significant features
produced by Information Gain has a substantial impact on improving detection
accuracy and execution time. The Random Forest method, for example, has the best
accuracy with 0.14% of negative results when using 22 relevant selected features,
whereas the Random Tree classifier algorithm has a higher accuracy with 0.13% of
negative results when using 52 relevant selected features but takes a longer execution
time.

Clinical Clue and Predictive Blood Count of Hemodialysis Cathether-Related Infection: Case Series
Authors: Vanessa Nadya , Primiawan Tatag
Published: November 2023

Most patients with chronic kidney disease (CKD) require renal replacement therapy. Majority of hemodialysis initiation is done through a dialysis catheter access. The use of catheters double lumen (CDL) for hemodialysis has several potential complications, including infection. Catheter related bloodstream infection (CRBSI) is associated with increased morbidity and mortality in CKD patients. CRBSI therapy should not be delayed, including delays due to waiting for culture results to confirm the diagnosis. Several studies have reported the use of clinical findings and routine blood count parameters to predict CRBSI. This case series reported three cases with suspected CRBSI consisting of one woman and two men with mean age of 44.67 ± 8.21 years, mean catheter days 13 ± 6.97, and mean hemodialysis duration of 10.5 ± 13.79 month. Diagnosis CRBSI was suspected from clinical clue, i.e symptoms such as fever and chills, pain at the CDL site, and physical examination i.e body temperature and local CDL site signs. Laboratory parameters in this case series reported elevations for PLR, NLR and SIRI supporting the suspicion of bloodstream infection.  All patients in this case series improved after CDL removal and antibiotics therapy. Investigation of clinical findings and routine blood count parameters can be an alternative diagnosis of CRBSI that enables prompt treatment in areas with limited facilities.

Aux pays des formes insolites : paysages botaniques et ordre naturel
Authors: Vuillemin Nathalie
Published: November 2023

La mission première des botanistes voyageurs, au xviiie siècle, relève de la collecte : il s’agit d’amasser autant d’échantillons naturels que possible afin d’alimenter l’entreprise classificatoire, d’une part, et de mettre en évidence l’utilité de la flore exotique, d’autre part. Cet article s’intéressera à la première partie de ce projet uniquement : nous montrerons comment certains naturalistes expriment leur perplexité face à une démarche qui leur semble insuffisante, trop peu attentive aux affinités des plantes telle qu’elles se manifestent en un lieu donné, à travers un paysage qui, mieux que tout système classificatoire, est susceptible de faire sentir l’ordre naturel.

Figures de (dé)rangement : de quelques tropes relationnels chez Jacques Delille
Authors: Marchal Hugues
Published: November 2023

Dans L’Homme des champs (1800) et Les Trois Règnes de la nature (1808), Jacques Delille établit de multiples parallèles entre des êtres qui lui semblent occuper des places diamétralement opposées sur des échelles de valeur hétéroclites, ses critères de classification des animaux tenant compte, par exemple, de l’anatomie des membres, du charme ou de la vitesse de différentes espèces. Toutefois, d’autres figures de style viennent complexifier cette tentative d’arpenter la nature grâce aux lignes tirées entre des couples antagonistes. Parallélismes de construction et autres syllepses retissent entre elles ces stries ou coupes, pour développer simultanément d’autres analogies et ainsi maximiser les “faisceaux” de relations, une ambition que Buffon juge interdite à sa prose, mais que la poétique de Delille réalise peut-être.

Poésie et physiologie végétale au tournant des XVIIIème et XIXème siècles : pour une préhistoire de l’écologie des relations
Authors: Weber Anne-Gaëlle
Published: November 2023

Cet article pourrait constituer une étape de la constitution d’une histoire “environnementale” des relations entre sciences et poésie. L’émergence de la physiologie végétale en tant que discipline, au tournant des XVIIIe et XIXe siècles, a entraîné, de la part de ses tenants, des recherches poétiques et formelles. Décrire le lien entre les organes des plantes et leur environnement a supposé de négocier, au sein des manuels et traités savants, de nouvelles articulations entre les critères de scientificité de la science émergente et des critères de définition de la poésie. Les représentants de la physiologie végétale ébauchent alors un certain nombre d’interrelations discursives et heuristiques qui pourraient aujourd’hui répondre à la nécessité de susciter chez le lecteur, par la forme même de l’ouvrage qui en traite, une attention renouvelée aux interrelations entre l’homme et la “nature”.

L’imagination et le vivant : une relation environnementale au siècle des Lumières
Authors: Kunz Westerhoff Dominique
Published: November 2023

Après avoir rappelé la fonction centrale qu’a joué l’imagination, en particulier l’imagination romantique, dans l’émergence de l’écocritique américaine et de l’écopoétique européenne, je propose d’y contribuer en remontant aux dernières décennies des Lumières, pour suivre le fil des liens de l’imagination au vivant dans quelques théories et discours français et francophones. À partir d’un choix concis de traités médicaux, d’essais philosophiques et de textes littéraires, notamment de Rousseau, l’enjeu consiste à cerner les transformations d’une imagination mécaniste héritée de Descartes – modèle particulièrement influent dans les sciences du XVIIIe siècle, mais problématique pour penser le vivant – en un modèle biocentrique qui ancre l’imagination dans les fibres du corps et dans une nature sensible. Plaque tournante des savoirs, l’imagination y est conçue comme l’instance par excellence de la relation, parce qu’elle inscrit le sujet dans son environnement. D’une relation perçue à une relation revécue, d’une relation heuristique à une relation inventée, elle se renverse d’une passivité mécanique en une activité générative qui fait de l’expérience du monde une connaissance des connexions, investie de valeurs morales, sociales et politiques. Mais comme on le verra dans la Contemplation de la nature (1781) de Charles Bonnet, c’est aussi l’instance d’une réflexivité critique permettant de mesurer les limites du savoir humain. 

Mots-clés : écocritique, écopoétique, imagination, romantisme, savoirs des Lumières, Rousseau, Charles Bonnet.

Una scena da riscrivere insieme. Il Laboratorio di Prato (1976-78)
Authors: Giovannelli Maddalena
Published: November 2023

Il teatro del Novecento vede, in Europa, un aumento dell’interesse verso il disegno dello spazio scenico. I processi di collaborazione e co-creazione cominciano così a comprendere sempre più spesso – accanto a drammaturghi e registi – anche architetti e progettisti, che modificano profondamente le pratiche della scrittura scenica. Il panorama italiano tarda a rispondere a questo fermento che si diffonde oltre confine, ma si distingue in questo quadro il Laboratorio di Progettazione Teatrale attivo tra il 1976 e il 1978, che vede il coinvolgimento di un gruppo di ricerca interdisciplinare. Il progetto è guidato formalmente da Luca Ronconi ma l’articolo mette in luce come l’apporto di diverse competenze, e soprattutto dell’architetta Gae Aulenti, vada considerato ugualmente importante a quello della regia, sia in relazione ai tre spettacoli prodotti, che all’ideazione dell’intero progetto. 

Parole chiave: teatro, spazio, scena, pubblico, Luca Ronconi, Gae Aulenti.
Modi e forme della collaborazione nei "Rabisch" dell’Accademia dei facchini della Valle di Blenio
Authors: Pezzini Enea
Published: November 2023

Nell’articolo si discutono i modi e le forme della collaborazione all’interno dell’Accademia dei facchini della Valle di Blenio e dei Rabisch dra Academiglia dor compà Zavargna… (‘Arabeschi dell’Accademia del Compare Zavargna…’, Milano, Gottardo Ponzio, 1589). Sebbene nel sodalizio facchinesco vi siano oltre cento membri, solo quindici di loro partecipano attivamente alla stesura della silloge plurilingue, anticlassicista e antitoscana. Giovanni Paolo Lomazzo ne risulta l’ideatore e la principale voce poetica e gli altri suoi sodali occupano un ruolo tutto sommato marginale, riconducibile a un loro recente ingresso nell’Accademia e finalizzato più che altro ad avallare le critiche linguistiche espresse nella raccolta. 

Parole chiave: Giovanni Paolo Lomazzo, Rabisch, Accademie, letteratura dialettale riflessa, Cinquecento.
Vittorio Sereni e Alessandro Parronchi, itinerari e collaborazioni tra arte e poesia
Authors: Fuchs Marino
Published: November 2023

Il saggio intende illustrare aspetti meno noti di alcune collaborazioni tra Sereni e Parronchi, esplorando la felice convergenza dei loro interessi su molteplici fronti: non solo la poesia, ma anche le arti figurative e l’ambito dell’editoria. In particolare, si darà conto della collaborazione che tra il 1952 e il 1958 portò alla creazione di alcune prose di viaggio per la rivista Pirelli. Itinerari in automobile dove il presente rievoca il passato e i paesaggi dipinti dei grandi maestri del Rinascimento. Una passione comune per l’arte che legherà i due poeti anche nel decennio successivo e che porterà alla scrittura di ‘Expertise’ per Vittorio, opera con la quale Parronchi tenterà di dare seguito al dialogo interrotto dalla morte dell’amico. 

Parole chiave: autorialità plurima, epistolari, mediatore interartistico, rivista Pirelli, letteratura di viaggio.
Otto mani per "Renga": il «poème collectif» di Octavio Paz, Jacques Roubaud, Edoardo Sanguineti e Charles Tomlinson
Authors: Portesine Chiara
Published: November 2023

Il contributo si propone di analizzare criticamente le strategie testuali e intertestuali che legano tra loro le sequenze plurilinguistiche di Renga (1969), un esperimento di «poème collectif» modellato sulla tradizione giapponese del renga, a cui presero parte Octavio Paz, Jacques Roubaud, Edoardo Sanguineti e Charles Tomlinson. La seconda parte dell’articolo si focalizzerà sulla prospettiva specifica di Sanguineti, utilizzando l’esempio del poeta genovese, apparentemente meno implicato degli altri co-autori nella costruzione di una voce autenticamente plurale, per verificare la tenuta di alcune dinamiche collettive. 

Parole chiave: renga, poème collectif, co-autorialità, plurilinguismo, intertestualità.
Las tres orillas: nadar a contracorriente. África, Europa y América Latina
Authors: Vauthier Bénédicte , Terrones Félix
Published: November 2023

En estos preliminares hacemos dialogar a la docena de autorxs que nos confiaron sus contribuciones en las que analizan las circulaciones, los flujos, los intercambios de personas y de ideas entre un lado y otro del Atlántico a lo largo del siglo xx, siendo el tercer eje de triangulación de todas ellas, Francia, tierra de ensueño o de acogida, a la que se llega con amor; o África, tierra de origen, de la que hombres y mujeres se vieron arrancados, para convertirse en herramientas del sueño colonial. ¿Cuáles son los eventos y/ o los elementos estructurales de las historias –políticas y estéticas– a los que se tendría que prestar más atención cuando se habla de relaciones transnacionales, trasversales, transatlánticas? ¿Cuáles son las categorías conceptuales e historiográficas que permitirían articular mejor estas historias? He aquí algunos de los interrogantes alrededor de los cuales se estructura este número de Versants y nuestra lectura del número. 

Palabras clave: España, América Latina, transatlántico, exilio, migración, circulación, política, estética
Modos de narrar, formas de conocer. Apuntes Eduardo Berti
Authors: Lombardo Martín
Published: November 2023

A partir de las reflexiones de Walter Benjamin y de Ricardo Piglia sobre la figura del narrador, el presente artículo analiza las novelas La sombra del púgil (2008) y Un padre extranjero (2016) de Eduardo Berti. Si el viaje y la investigación son, a la vez, formas de narrar y modos del saber, se estudia cómo circulan las historias y los saberes en ambos textos. Más que crear una zona de certezas, las narraciones multiplican los puntos de vista y configuran un saber marcado por los silencios, el misterio y los secretos. De los modos de conocimientos a los que se accede a través de las historias se vislumbra lo ausente y así surgen los deseos. 

Palabras clave: secreto, silencio, narrador, experiencia, deseo.
Teatro mágico, teatro fantástico: tres piezas de Hugo Argüelles
Authors: Mondragón Cristina
Published: November 2023

aEntre las múltiples particularidades que hicieron único al dramaturgo Hugo Argüelles (Veracruz, 1932-CDMX 2003), quizás la más conocida sea el uso constante de objetos mágicos en su obra. Estos motivos llevan la obra del dramaturgo a lo maravilloso, aunque con algunos rasgos de lo fantástico, como sucede en Los amores criminales de las vampiras Morales y La esfinge de las maravillas. En cambio, una clara muestra de lo fantástico aparece en El gran inquisidor. Auto profano, donde el escritor acude al metateatro para lograr una transgresión que no logra explicarse en la obra misma. Veremos, entonces, cómo Argüelles se acerca a las fronteras de lo fantástico cuando trabaja sobre las obsesiones del incesto y cómo logra una pieza fantástica con la figura de Tomás de Torquemada. 

Palabras clave: metateatro, fantástico, teatro fantástico, teatro mexicano, objetos mágicos.
