Búsqueda de la innovación y crítica política en el teatro poético canario (1955-1974): Oí crecer a las palomas, de Manuel Padorno; Cuatro estudios en negro, de Gilberto Alemán de Armas; y Vladimir Mayakowsky (tragedia)- koúmos, de Sabas Martín-Vladimir Mayakowsky
Authors:   Universidad de La Laguna (España), García de Mesa Roberto
Published: December 2024

This article analyzes three textual and stage milestones that contribute to outlining a schematic panorama of innovative theatrical activity in the Canary Islands; the three plays were also critical of the Franco regime between 1955 and 1974. The pieces chosen are Oí crecer a las palomas (1955), by Manuel Padorno; Cuatro estudios en negro (1964), by Gilberto Alemán de Armas, and Vladimir Mayakowsky (Tragedy)-Koúmos (1974), by Sabas Martín-Vladimir Mayakowsky. Indeed, they have in common that all three were performed and the texts have been preserved. The plays were also heirs to the avant-garde theater of the first half of the 20th century, and their creators searched for formal and linguistic innovation. They belong to the tradition of avant-garde poetic theater, which seeks to investigate new forms and bring the most contemporary and innovative poetry to the stage. At the same time, political criticism against totalitarianism and against the system that oppresses individual freedom is expressed in the texts. In all three cases, in one way or another, the texts also try to refer to the prevailing system. The weight of censorship during the Franco dictatorship probably conditioned these authors, who used various strategies to circumvent it.
Un diálogo inconcluso. La relevancia de la intertextualidad en la narrativa concentracionaria de Jorge Semprún
Authors:   Universidad Complutense de Madrid (España), Mendieta Rodríguez Elios
Published: December 2024

This article delves into the importance of intertextuality in Jorge Semprún’s work and, specifically, in his four concentration memoirs: El largo viaje (1963), Aquel domingo (1980), La escritura o la vida (1994) and Viviré con su nombre, morirá con el mío (2001). The aim is to explain why the systematic recurrence of quotations is a key fact in the writer’s way of narrating, of awakening his memory; and, above all, to show how the intertexts are decisive in understanding the writer’s style and the main topics presented in his writings on the concentration camps and his experience as a prisoner in Buchenwald. Therefore, the main authors and texts invoked by Semprún in his literary works are analyzed; in parallel, a comparative approach is carried out that reflects on how, in his books, the writer engaged in a dialogue with this group of creators.
Eterno femenino» en Cristóbal de Castro y en su traducción de Eva moderna (1921), de Scipio Sighele
Authors:   Universidad Complutense de Madrid (España), Ocampos Palomar Emilio José
Published: December 2024

Cristóbal de Castro (1874-1953) has been considered a feminist author by some scholars and editors of his work. This consideration is insufficient if the emphasis is only made on the author as someone who wrote to describe women, not paying attention to the typology of his female characters. Since what type of woman does Castro present in his work? Furthermore, it is also insufficient if translation is not considered part of his writing and the treatment of women in his translated works is ignorEd. In the following essay, Castro’s thinking on women as reflected in his literary and journalistic work is studied, as well as in the translation of Eva moderna (1921), which was made by the Italian Scipio Sighele. Attention is paid to the ideological affinity between the author and the translator to reflect on whether the texts of both authors are committed to a new model of woman that goes beyond the nineteenth-century codes, which situated women in the sphere of the private and feelings, or, on the contrary, whether they reproduce an «eternal feminine», that is, an image of women dominated by men as an eternal truth, which, according to the theory of immanence, makes the emancipation of women and their conquest of the public sphere impossible.
El español en contacto con el portugués europeo: producción y percepción de los pretéritos perfectos simple y compuesto
Authors:   Universidad de Salamanca (España), Tellez-Perez Clara
Published: December 2024

Time is the key concept in the traditional theories whose aim is to describe past tenses in Spanish. Regarding Past Simple (PS) and Present Perfect (PP), defining the core meaning of both tenses has proven to be a complex task, especially due to the evolution that the PP is experiencing, not only in Spanish, but in other romance languages, too. The goal of this study is to delve into the differences of PS and PP in a situation of linguistic contact between Peninsular Spanish and European Portuguese. In order to achieve this, an experiment was designed with a focus on the analysis of production and psycholinguistic perception. This double approach constitutes an innovation in this field. The data obtained was subjected to statistical analysis. This study confirmed that, indeed, there are significant differences between the production of PS and PP in Spanish depending on informants’ sex and country of residence. Said differences also affect psycholinguistic perception and they are especially notable in prehodiernal contexts as well as in situations closely linked to the Moment of Speech (MS).

Published: December 2024

Sensitivity to color and its use for expressive purposes is an anthropological universal. The peculiarity of Greek civilization within that general panorama, and more specifically within its own cultural development, consists in the effort invested in theoretically unraveling its nature. As part of this project, considering the adoption of certain terms in the first place is unavoidable, followed by exploring the gradual conceptual prioritization undertaken after a long trajectory that begins with the Homeric epic, has been consolidated since the dawn of philosophy, and concludes with the systematizing work of Aristotle. Finding the keys to this development is the purpose that prompts the writing of this article.

Published: December 2024

Formation by students of reporting documents for their works and the subsequent procedure of norm control by the educational organization is an integral part of the educational process in universities. In the absence of a proper level of knowledge on the part of the student, students often commit violations of the registration standards of reporting works, identified in the course of the planned educational organization inspection, which leads to repeated procedures of norm control and deterioration of the educational process. The article considers the importance of the registration quality skill of reporting works performed by students in the process of educational activity, as well as possible methods for the formation of the described skill in the digital environment.

Over the past few decades, the number, variety, and complexity of time series forecasting models have grown. There has also been an increased interest among researchers in comparing and assessing the predictive accuracy and performance of models, and in determining which models are more accurate. The researchers propose using the hypothesis testing approach to assess the performance of a time series forecast model. They obtained data for the study while monitoring the dynamics of ground-level concentrations of the main greenhouse gases on the Arctic Island of Bely, Yamalo-Nenets Autonomous Area, Russia. A total of three models based on autoregressive neural networks with exogenous input (NARX) were considered to predict changes in methane concentration in the surface layer of atmospheric air. The performance of the models was assessed using 8 “traditional” indices (correlation and determination coefficients, Wilmott goodness-of-fit indices, mean absolute error, relative mean square error, etc.) and the proposed permutational approach using the hypothesis testing method. In general, based on the data under study, the estimates of the permutation approach and other indicators of accuracy and error coincide, but there are discrepancies. Effect sizes do not always determine the statistical significance of differences.

Published: December 2024

In recent years, there has been a significant increase in maritime economic activity in the Arctic zone of the Russian Federation. The intensification of shipping in the Arctic waters leads to an increase in greenhouse gas emissions, for the accurate assessment of which there are currently no effective tools. The study proposes a methodology for the general quantification of emissions from shipping in a specific water area, based on the use of AIS data from satellite systems. Using the proposed approach, the authors for the first time have assessed and analyzed the structure of shipping traffic as a source of emissions and established the dynamics and volumes of greenhouse gas emissions in a specific area of the Arctic water area.
On the need to develop a comprehensive system of preventive measures against deformations of buildings and structures in the cryolithozone under climate change

As a result of increasing permafrost degradation, caused by climate warming, there is a growth in the number of deformations of buildings and structures in the regions of the Russian Arctic. The article examines in detail examples of building deformations in the north of the European part of Russia, in Western and Eastern Siberia, and on the Russian Arctic coast. The authors analyze and typify main causes of contingency situations. These include insufficient engineering and geological surveys, design errors, poor-quality construction of buildings and structures and violations of current standards for their operation. A serious risk factor in the construction and operation of civil and industrial facilities in the Arctic zone of the Russian Federation caused the liquidation of the previously existing system for monitoring the condition of capital structures, design and technical services that specialized in the restoration and repair of damaged buildings. At the same time, following up the construction practice without taking into account regional forecasts of the permafrost state under climate change can multiply the damage from global warming. To solve the problem, it is necessary to restore the system of control, notification and protection of structures, based on the creation of a federal system for permafrost monitoring, including background and geotechnical components, and uniting various departments and economic entities. This measure will significantly reduce the technical and environmental costs of current economic activity in the Russian Arctic.
From Risk to Readiness: Exploring Community Preparedness for Monsoon Floods in East Coast Malaysia
Authors: Hosen Nadzirah , Kamarudin Khairul Hisyam , Mohamad Fauzi Mohamad Hafiz
Published: December 2024

Floods during the monsoon season are a recurring phenomenon in Malaysia’s East Coast, with Kelantan communities frequently affected from November to March. These floods cause significant loss of life and economic damage, emphasising the need for increased awareness and preparedness. This study employs quantitative research methods to evaluate the preparedness of the Tok Deh community in Kelantan who experienced severe floods in 2014 and 2022. Fifty respondents completed a questionnaire assessing five indicators: knowledge of floods, reading flood signs, flood adaptation, flood awareness and flood perception.

The results indicate high community knowledge about floods (mean score, M = 3.82) and a strong belief that floods are inevitable during monsoons (4.42). The community showed high confidence in Government support post-flood (4.36 - 4.42), effective sharing of flood-related knowledge (4.42) and high awareness of evacuation centre locations (4.44). However, participation in disaster awareness campaigns (3.52) and awareness of the importance of infrastructure (3.68) need improvement. Confidence in the safety of homes and buildings is moderate to low (2.32 - 2.72). Although the community anticipates large-scale flooding within the next decade (4.10), individual preparedness remains inadequate. This study highlights the community’s strong flood-related knowledge and collective preparedness and calls for improved personal preparedness, expert knowledge access and communication with non-governmental organisations to enhance resilience.
Development of a GPS-GPRS tracked surface drifter for monitoring of surface currents in tidally dominated estuaries
Authors: Jaini Sara Babu , Kochuparampil Ajith Joseph , Roshin P. Raj
Published: December 2024

The Vembanad estuary is one of the largest estuarine systems in India, heavily influenced by monsoonal variations and coastal dynamics. As industrial development and navigation activities increase in the region, understanding the estuary's circulation patterns, predominantly driven by tidal currents, has become crucial. This is essential for assessing the dispersal of industrial waste, sediment transport and ensuring safe and efficient navigation for meeting any disaster preparedness. However, collecting precise circulation data near shorelines remains difficult with traditional field deploying current meters and satellite altimeters due to different logistic challenges and land-sea interactions respectively.

Additionally, advanced instruments such as Acoustic Doppler Current Profilers (ADCPs) are not well-suited for shallow water environments. To address this challenge, an indigenously developed surface drifter, based on the Lagrangian technique, has been designed and tested for real-time monitoring of circulation and tidal currents in the estuary. The drifter is equipped with a GPS (Global Positioning System) module and a GPRS (General Packet Radio Service) module, allowing for real-time tracking. By analyzing GPS data collected at regular intervals, current patterns in the estuarine region can be effectively studied. A comparison between current flow patterns measured by the surface drifter and an in situ current meter demonstrated a strong correlation, validating the drifter’s accuracy in capturing estuarine circulation data which signifies the utility of such devices for remotely monitoring.
BRITE Nascent Binaries
Authors: Pigulski Andrzej
Published: December 2024

Nascent binaries (NBs) are binary systems with very low mass ratios, less than ∼0.2, in which the more massive component is an O- or B-type main-sequence star, while the secondary is a star contracting onto the main sequence. NBs are of interest because they can help to under- stand the formation of small-mass ratio systems and shed light on the origin of low-mass X-ray binaries, millisecond pulsars and type Ia supernovae. In photometry, short-period NBs show a strong irradiation effect due to the large difference between the effective temperatures of the components and the strong irradiation of a cool secondary by a hot primary. In spectroscopy, they usually appear as single-lined spectroscopic binaries. In the present paper, we summarize the status of our knowledge of Galactic nascent binaries and characterize two new members of this group, c2 Sco and V390 Pup, for which photometric data were obtained by the BRIght Target Explorer (BRITE) nano-satellite mission.
Apsidal Motion in Massive Binaries: Or How to Sound Stellar Interiors Without Asteroseismology
Authors: Rosu Sophie
Published: December 2024

The determination of the apsidal motion in close eccentric binary systems is (one of) the most efficient and reliable observational technique allowing to probe the internal structure of a star. The apsidal motion is the secular precession of the binary orbit’s major axis and it is dependent on the tidal interactions occurring between the two stars. The apsidal motion rate is directly related to the internal structure of the stars, in particular their inner stellar density profile. The rate of apsidal motion can be constrained, together with the fundamental parameters of the stars, through state-of-the-art adjustment of combined radial velocity and light curve measurements made over a long timescale. The internal structures of the stars are subsequently constrained through the confrontation of the observationally determined parameters to theoretical models of stellar structure and evolution. This powerful technique has been known for years but has been seldom applied to massive stars. I highlight its interest and discuss recent results concerning several massive binaries, among others one binary that captured our attention for decades notably due to its twin property: HD 152248. While standard 1D stellar evolution models predict stars having a smaller internal stellar structure constant, that is to say, stars having a lower density contrast, than expected from observations, I demonstrate that the addition of mixing inside the models helps to solve, at least partially, this discrepancy. Whether this additional mixing might be fully explained by rotational mixing is under investigation. Ongoing studies with the non-perturbative code MoBiDICT show that the perturbative model assumption is not justified in highly distorted stars. In these cases, the apsidal motion is underestimated, which exacerbates even more the need for enhanced mixing inside the models.
Solving the Mystery of Extreme Light Variability in the Massive Eccentric System MACHO 80.7443.1718

Published: December 2024

The evolution of massive stars is heavily influenced by their binarity, and the massive eccentric binary system MACHO 80.7443.1718 (ExtEV) serves as a prime example. This study explores whether the light variability of ExtEV, observed near the periastron during its 32.8-day orbit, can be explained by a wind–wind collision (WWC) model and reviews other potential explanations. Using broadband photometry, TESS data, ground-based UBV time-series photometry, and high- resolution spectroscopy, we analysed the system’s parameters. We ruled out the presence of a Keplerian disk and periodic Roche-lobe overflow. Our analysis suggests the primary component has a radius of about 30 R⊙, luminosity of ∼6.6×105 L⊙, and mass between 25 and 45 M⊙, with a high wind mass-loss rate of 4.5×10−5 M⊙ yr−1, likely enhanced by tidal interactions, rotation, and tidally excited oscillations. We successfully modelled ExtEV’s light curve, identifying atmospheric eclipse and light scattering in the WWC cone as key contributors. The system’s mass-loss rate exceeds theoretical predictions, indicating that ExtEV is in a rare evolutionary phase, offering insights into enhanced mass loss in massive binary systems.
Prises en flagrant délit: signatures d'épisodes passés d'échanges de matière dans des binaires massives?
Authors: Rauw Gregor
Published: December 2024

Many massive binary systems undergo mass and angular momentum transfer over the course of their evolution. This kind of interaction is expected to deeply affect the properties of the mass donor and mass gainer and to leave various observational signatures. The most common smoking guns of a past mass transfer episode are notably rapid rotation of the mass gainer and altered surface chemical abundances of the stripped mass donor star. Quantitative observational studies of evolved massive binaries are crucial to gain insight into poorly constrained parameters of binary evolution models such as the fraction of mass lost by the mass donor that is actually accreted by the mass gainer. Yet, drawing conclusions about a past mass transfer episode requires a detailed analysis of all aspects of a binary system which sometimes leads to unexpected results. In this contribution, we review the existing observational evidence for past mass exchange events in massive main-sequence and post main-sequence binaries.
Runaway O and Be Stars Found Using Gaia DR3, New Stellar Bow Shocks and Search for Binaries
Authors: Carretero-Castrillo Mar , Ribó Marc , Paredes Josep M. , Benaglia Paula
Published: December 2024

A relevant fraction of massive stars are runaways, moving with a significant peculiar velocity with respect to their environment. Kicks from supernova explosions or the dynamical ejection of stars from clusters can account for the runaway genesis. We have used Gaia DR3 data to study the velocity distribution of massive O and Be stars from the GOSC and BeSS catalogs and identify runaway stars using a 2D-velocity method. We have discovered 42 new runaways from GOSC and 47 from BeSS, among a total of 106 and 69 runaways found within these catalogs, respectively. These numbers imply a percentage of runaways of ∼25% for O-type stars ∼5% for Be-type stars. The higher percentages and higher velocities found for O-type compared to Be-type runaways suggest that the dynamical ejection scenario is more likely than the supernova explosion scenario. We have also performed multi-wavelength studies of our runaways. We have used WISE infrared images to discover 13 new stellar bow shocks around the runaway stars. We have also conducted VLA radio observations of some of these bow shocks. Finally, our runaway stars include six X-ray binaries and one gamma-ray binary, implying that new such systems could be found by conducting detailed multi-wavelength studies. In this work we report on this ongoing project to find new runaway stars, study their interaction with the ISM and search for high-energy binary systems.
Interacting Winds and Giant Eruptions in Massive Binaries
Authors: Kashi Amit
Published: December 2024

Massive stars eject strong winds that affect their evolution. When in a binary system, their winds collide and emit radiation across the spectrum, providing an opportunity to study the stars and the interaction between them. There are many physical effects involved in the colliding-wind problem, and its complexity requires 3D numerical simulations. When one of the star is accreting the simulations become more complex. We present simulations of colliding winds in massive binary systems that include a detailed treatment of wind ejection, orbital motion, clumpiness, and other effects. These simulations are applied to different kinds of massive binaries that include LBVs, WR-stars, B[e] Supergiants, and O stars, in various primary–secondary combinations. We present results of simulations from some of the systems we studied. We show systematic simulations that were used to determine the general conditions that may lead to accretion onto the secondary star, and obtain the new sub-Bondi–Hoyle–Lyttleton accretion, with relationships between the mass accretion rate and the ratio of the stellar wind momentum. We also present recent results showing how the accreting secondary star responds to very high accretion rates, such as in giant LBV eruptions, and show how jets can suppress the accretion rate in such systems.
Analyse en rayons X des collisions de vents stellaires dans HD 168112 et HD 167971
Authors: Rauw Gregor , Blomme Ronny , Nazé Yaël , Volpi Delia
Published: December 2024

The O-type long-period binary HD 168112 and triple HD 167971 star systems have been known for several decades for their non-thermal synchrotron radio emission. This emission arises from relativistic electrons accelerated in the hydrodynamic shocks of the wind collisions in these systems. Such wind collisions are expected to produce a strong X-ray emission that varies as a function of orbital phase. In wide eccentric binaries, such as our targets, the X-ray emission arises from an adiabatic plasma and its intensity should scale as the inverse of the orbital separation. We present a set of XMM-Newton observations of these systems which help us gain insight into the properties of their wind interactions.

HD 168112 is a non-thermal radio emitter that has only recently been confirmed as a spectroscopic binary by Putkuri et al. (2023, DOI: 10.1093/mnras/stad2657). We use an independent set of spectroscopic observations to determine its orbital parameters. We also analyse radio observations we collected around its periastron passage. While other orbital phases clearly show non-thermal emission, the phases near periastron are thermal and are dominated by the free–free emission in the colliding-wind region.

Published: December 2024

Представлен опыт применения сварки металлов взрывом на Урале. Также рассказывается о создании лаборатории импульсной обработки металлов (ЛИОМ), сотрудниками которой на основе анализа обширных экспериментальных данных разработана методика определения оптимальных технологических параметров сварки взрывом различных пар металлов. Внедрение методики в производство позволило свести процент брака практически до нуля. Описаны современные теоретические и экспериментальные исследования, проводимые ЛИОМ на производственной площадке ООО «Протол», связанные с обработкой материалов энергией взрыва. Наиболее подробно рассмотрен вопрос по определению предельно допустимой массы накладного заряда при сварке взрывом. Результаты, полученные в данной работе, были использованы в 2021 г. при подготовке скорректированного проекта взрывных работ для сварки металлов на полигоне для предприятия ООО «Протол».

The article presents the experience of using explosion welding of metals in the Ural region. It also tells about the creation of a laboratory for pulsed metal processing (LPMP), which, based on the analysis of extensive experimental data, developed a method for determining the optimal technological parameters for welding various pairs of metals. The introduction of the technique into production allowed to reduce the percentage of defects to almost zero. Modern theoretical and experimental studies conducted by LPMP at the production location of LLC “Protol” related to the processing of materials by explosion energy are described here. The issue of determining the maximum permissible mass of the pressure charge during explosion welding is that we consider in the most detail. The results obtained in this work were used in 2021 in the preparation of an adjusted project of blasting operations for welding metals at the testing area for the LLC "Protol".

Laryngomalacia is the most common anomaly of laryngeal evolution. At the moment, the classical method of surgical treatment using standard surgical instruments is mainly used. The method of cold plasma ablation has proven itself well in surgery, including operations on the lymphopharyngeal ring. However, in Russia it is not used for the treatment of children with congenital laryngomalacia.

Ларингомаляция – это наиболее частая аномалия развития гортани. На данный момент преимущественно используется классический метод хирургического лечения с использованием стандартных хирургических инструментов. Метод холодно-плазменной аблации хорошо себя зарекомендовал в хирургии, в т.ч. при операциях на лимфоглоточном кольце. Однако в России он практически не используется для лечения детей с врожденной ларингомаляцией.

Cases of iatrogenic dissemination of tumor cells during surgery were described as early as the end of the 19th century. Currently, a small number of cases of iatrogenic surgical contamination with malignant tumors in the form of implantation metastases are described in the world literature. This is probably due to the improvement of asepsis rules, the modification of surgical techniques, and the increased oncological alertness of medical personnel during surgery. Clinical case. In the article, we describe a clinical case of surgical resection of skin cancer on the right side of external nose (Mercel cell carcinoma), with reconstruction with a radiation flap, at the site of which, 11 months after the operation, implantation metastasis was realized in the postoperative scar of the donor wound. Currently, Merkel cell carcinoma is a poorly understood disease, especially its metastatic potential and aggressive growth pattern. Unfortunately, there are no uniform world standards, protocols, practical recommendations, and consensus among practicing surgeons regarding minimizing the potential risks of mechanical tumor implantation during oncological operations.

Случаи ятрогенной диссеминации опухолевых клеток во время хирургического вмешательства описыва- лись еще в конце ХIХ века. В настоящее время в мировой литературе описано небольшое число случаев ятрогенной хирургической контаминации злокачественными опухолями в виде имплантационных метастазов. Вероятно, это связано с усовершенствованием правил асептики, модификацией хирургических методик и повышением онкологической настороженности медицинского персонала во время операции. Клинический случай. В статье описан клинический случай удаления рака кожи наружного носа справа из клеток Меркеля, с реконструкцией кожно-фасциальным лучевым лоскутом, на месте которого через 11 месяцев после операции в послеоперационном рубце донорской раны реализовался имплантационный метастаз. В настоящее время карцинома Меркеля является мало изученным заболеванием, в особенности ее ме- тастатический потенциал и агрессивный характер роста. К сожалению, нет единых мировых стандартов, протоколов, практических рекомендаций и единого мнения среди практикующих хирургов относительно минимизации потенциальных рисков механической опухолевой имплантации во время онкологических операций.
