Authors: Xu Xueyan , Yu Zhijin , Li Yang , Wang Weifeng , Xu Lan
Published: July 2021

To clarify the understanding and analysis of arc molten marks in electrical faults of aluminum alloy wires, this paper simulates overcurrent faults of aluminum alloy wires at currents of 128 A–224 A and uses thermogravimetry-differential scanning calorimetry (TG-DSC), optical microscope (OM), scanning electron microscope (SEM) and X-ray energy spectroscopy (EDS) to characterize the effects of current on the microstructure of arc beads. The results show that there are small and large amounts of Al-Si and Al-Fe binary phases in the metallographic structure of the aluminum alloy wires at the rated current, the grains are fine, and there are no significant grain boundaries. After an overcurrent fault occurs in the wires, a high-temperature arc causes the second phase in the aluminum alloy to disappear, a cellular dendritic metallographic structure appears, the grain boundaries become more well-defined, and composition segregation occurs at the grain boundaries. Using Image-Pro-Plus software to quantify the grain characteristics, the average grain size is found to gradually decrease as the current increases. In addition, by comparing and analyzing the characteristics of arc beads in aluminum wires and aluminum alloy wires under the same conditions, alloying elements are found to have a refining effect on the grain boundaries, and there are coarse precipitates at the grain boundaries in the aluminum wire arc beads.

Published: July 2021

In the gel-casting process, the proper selection of technological parameters is crucial for the final quality of a green body. In this work, the finite element method is used to investigate the mold characteristics in the gel-casting process, and the typical flow behaviors under different conditions are presented. Based on the distribution characteristics of temperature, pressure and flow field of gel polymer, the simulated results provide some possible reasons for the generation mechanisms of defects. Then, a series of simulations were performed to investigate the effect of process parameters on the molding quality of green gel-cast bodies. The results show that the decreasing loading speed can effectively reduce the number of defects and improve the molding quality. In addition, this paper presents a new technique by applying the exhaust hole to decrease the number of defects and, hence, improve structural integrity. The influence of the loading speed on the mold characteristics is well understood for the gating system with an exhaust hole, which suggests to us appropriate parameters for optimizing the molding design. This work provides a theoretical basis to explicate the generating mechanism of defects involved in the gel-casting process and acquires an optimized technique to produce a silicon carbide green body.

Authors: Wang Yanju , Lin Zhiyang , Tang Can , Hao Wenfeng
Published: July 2021

The amounts of the components in a microcapsule self-healing system significantly impact the basic performance and self-healing performance of concrete. In this paper, an orthogonal experimental design is used to investigate the healing performance of microcapsule self-healing concrete under different pre-damage loads. The strength recovery performance and sound speed recovery performance under extensive damage are analyzed. The optimum factor combination of the microcapsule self-healing concrete is obtained. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) are carried out on the concrete samples before and after healing to determine the healing mechanism. The results show that the healing effect of self-healing concrete decreases with an increase in the pre-damage load, and the sound speed recovery rate increases with an increase in the damage degree. The influence of the sodium silicate content on the compressive strength and compressive strength recovery rate of the self-healing concrete increases, followed by a decrease. The optimum combination of factors of the microcapsule self-healing system is 3% microcapsules, 30% sodium silicate, and 15% sodium fluosilicate. The results can be used for the design and preparation of self-healing concrete.

Published: July 2021

Cross-laminated Timber (CLT) has become an emerging board material of wood construction that is strong enough to sustain a high-rise building. However, many wooden congregate housing units overseas that utilize CLT have poor sound environments because the low mass of such wood influences sound insulation performance. In this research, we explored the effect of different CLT walls on sound insulation performance and integrated applicable sound insulation simulation tools to simplify the process of designing a CLT wall structure. This research aimed at a double wall and CLT combined with a gypsum board as the research object. The sound insulation performance test was carried out in a laboratory, while the sound insulation performance of the structure was predicted through simulation tools and prediction models and then compared with the measured values to verify the applicability of the simulation tool. The CLT with a double wall and CLT with gypsum board (CLT + GB) achieved Rw of 50 dB. The numerical simulation had better prediction performance than INSUL at the double wall, while the double wall with cavity structure was close to the measured result via mass law calculation. The INSUL-predicted CLT with a gypsum board at 500 Hz~3150 Hz was close to the measured value.

Published: July 2021

Background and Objectives: Preserving the recurrent laryngeal nerve (RLN) is important in thyroid surgery. However, no standardized surgical method for locating the RLN has been established. We defined a new anatomical definition termed “lower central triangle” (LCT) for consistent identification of RLN and used intraoperative nerve monitoring (IONM) to aid in identification and dissection of RLN. Materials and Methods: Patients undergone thyroidectomy were reviewed retrospectively in Seoul National University Bundang Hospital from January to September 2017. Patients with papillary thyroid carcinoma, follicular neoplasm, and Graves’ Disease were included while right side non-RLN in arteriosus lusoria, cancer invasion, pre-existing vocal cord palsy, or under the age of 18 were excluded. RLNs were tested with IONM within LCT consisting of the lower pole as the apex and the common carotid artery as the opposite side. The samples were divided into two groups, IONM and non-IONM. Results: Forty lobes in total were included, 22 in IONM group and 18 in non-IONM group. Groups were not significantly different in age, cancer proportion, and accompanying thyroiditis while sex and nodule size differed. RLN detection time was 10.43 s shorter (p < 0.001), and confirmation time was 10.67 s shorter (p = 0.09) in IONM group than in non-IONM group. Both right and left RLNs were located predominately in the middle of LCT. No transient or permanent vocal cord palsy occurred. Conclusions: While IONM is an appropriate aid for thyroidectomy, our approach using LCT to locate the RLN is a novel definition of anatomy that provides prompt identification of the RLN in thyroid surgery.

Authors: Mesceriakova-Veliuliene Olga , Kalediene Ramune
Published: July 2021

Background and Objectives: Reduction in health inequalities is a highly important task in public health policies worldwide. In Lithuania, inequalities in mortality by place of residence are among the greatest, compared to other European Union (EU) countries. However, studies on inequalities in mortality by place of residence over a long-term period have not been investigated in Lithuania. The aim of this study was to present changes in mortality inequalities in urban and rural populations during 1990–2018. Materials and Methods: Mortality rates from all causes, cardiovascular diseases, cancer, external causes, and gastrointestinal diseases in urban and rural population by sex were calculated per 100,000 populations and were standardized by age. Inequalities in mortality were assessed using rate differences and rate ratio. For the assessment of inequality trends during 1990–2018, the joinpoint regression analysis was applied. Results: Mortality between urban and rural populations varied. In rural areas, mortality lower than that in urban areas was observed only in 1990 among women, in case of mortality from cancer and gastrointestinal diseases (compared with in 2018) (p < 0.05). In 2018, mortality from all causes, cardiovascular diseases, and external causes in urban and rural areas was lower than in 1990 in both sexes. However, mortality from gastrointestinal diseases was higher (p < 0.05). In 2018, mortality from cancer among both sexes was lower only in urban areas (p < 0.05). Mortality inequalities between rural and urban areas decreased statistically significantly only among men from external causes and from all causes (respectively, on average, by 0.52% per year and, on average, by 0.21% per year). Meanwhile, mortality from cardiovascular and gastrointestinal diseases increased in both sexes, and mortality from cancer and all causes of death increased among women. The increase in the inequalities of mortality from gastrointestinal diseases was the most rapid: among men—on average, by 0.69% per year, and among women—on average, by 1.43% per year, p < 0.0001. Conclusions: During 1990–2018, the inequalities in mortality by place of residence in Lithuania statistically significantly decreased only among men, in terms of mortality from external causes and from all causes. Therefore, reduction in inequalities in mortality must be the main the health policy challenge in Lithuania.

Published: July 2021

Athletes are exposed to a tremendous amount of stress, both physically and mentally, when performing high intensity sports with frequent practices, pushing numerous athletes into choose to use ergogenic aids such as caffeine or β-alanine to significantly improve their performance and ease the stress and pressure that is put onto the body. The beneficial or even detrimental effects of these so-called ergogenic aids can be appreciated through the use of numerous diagnostic tools that can analyze various body fluids. In the recent years, saliva samples are gaining more ground in the field of diagnostic as it is a non-invasive procedure, contains a tremendous amount of analytes that are subject to pathophysiological changes caused by diseases, exercises, fatigue as well as nutrition and hydration. Thus, we describe here the current progress regarding potential novel biomarkers for stress and physical activity, salivary α-amylase and salivary cortisol, as well as their use and measurement in combination with different already-known or new ergogenic aids.

Published: July 2021

Background: the COVID-19 pandemic and the implemented restrictions have changed the functioning of healthcare systems worldwide. The purpose of the study was to evaluate the impact of the present epidemiological situation on patients’ decisions about undergoing weight loss surgery. Methods: data were collected from 906 bariatric patients by the means of a national online survey, the majority of whom were women (87.9%). The survey started on 9 April 2020 and was open until 28 April 2020. The questionnaire included multiple choice and open questions, divided into three chapters: general information about the patient, life during the COVID-19 pandemic, and bariatric care during the COVID-19 pandemic. Results: despite the pandemic and the associated risk of COVID-19 infection, 443 responders (48.9%) would have decided to undergo bariatric surgery. Awareness of the negative impact of obesity on the course of COVID-19 illness had only marginable impact on patients’ decision-making (76.6% vs. 75.3%; p < 0.80). Contact with COVID-19 prior to the survey had a negative impact on the willingness to undergo bariatric surgery (3.0% vs. 4.4%; p < 0.55). There was a positive correlation between the BMI and preference for bariatric surgery in the time of the pandemic (37.4 ± 9.0 vs. 34.9 ± 8.7; p < 0.001). Conclusions: the level of awareness about the advantages of operative treatment of obesity is high among bariatric patients. The majority of patients awaiting bariatric surgery at the moment of the survey were positive about undergoing bariatric surgery despite the increased risk of a serious course of COVID-19 infection. Therefore, a large proportion of patients was determined to have bariatric treatment even during the pandemic, being aware of the increased risk of worse pace of COVID-19 disease in case of obesity and related diseases.
Semiconductor Chip Electrical Interconnection and Bonding by Nano-Locking with Ultra-Fine Bond-Line Thickness

Published: July 2021

The potential of an innovation for establishing a simultaneous mechanical, thermal, and electrical connection between two metallic surfaces without requiring a prior time-consuming and expensive surface nanoscopic planarization and without requiring any intermediate conductive material has been explored. The method takes advantage of the intrinsic nanoscopic surface roughness on the interconnecting surfaces: the two surfaces are locked together for electrical interconnection and bonding with a conventional die bonder, and the connection is stabilized by a dielectric adhesive filled into nanoscale valleys on the interconnecting surfaces. This “nano-locking” (NL) method for chip interconnection and bonding is demonstrated by its application for the attachment of high-power GaN-based semiconductor dies to its device substrate. The bond-line thickness of the present NL method achieved is under 100 nm and several hundred times thinner than those achieved using mainstream bonding methods, resulting in a lower overall device thermal resistance and reduced electrical resistance, and thus an improved overall device performance and reliability. Different bond-line thickness strongly influences the overall contact area between the bonding surfaces, and in turn results in different contact resistance of the packaged devices enabled by the NL method and therefore changes the device performance and reliability. The present work opens a new direction for scalable, reliable, and simple nanoscale off-chip electrical interconnection and bonding for nano- and micro-electrical devices. Besides, the present method applies to the bonding of any surfaces with intrinsic or engineered surface nanoscopic structures as well.
The Window Matters: A Systematic Review of Time Restricted Eating Strategies in Relation to Cortisol and Melatonin Secretion
Authors: Chawla Shreya , Beretoulis Spyridon , Deere Aaron , Radenkovic Dina
Published: July 2021

Time-Restricted Eating is an eating pattern based on the circadian rhythm which limits daily food intake (usually to ≤12 h/day), unique in that no overt restriction is imposed on the quality, nor quantity, of food intake. This paper aimed to examine the effects of two patterns of TRE, traditional TRE, and Ramadan fasting, on two markers of circadian rhythm, cortisol and melatonin. PubMed and Web of Science were searched up to December 2020 for studies examining the effects of time restricted eating on cortisol and melatonin. Fourteen studies met our inclusion criteria. All Ramadan papers found statistically significant decrease in melatonin (p < 0.05) during Ramadan. Two out of the three Ramadan papers noted an abolishing of the circadian rhythm of cortisol (p < 0.05). The non-Ramadan TRE papers did not examine melatonin, and cortisol changes were mixed. In studies comparing TRE to control diets, Stratton et al. found increased cortisol levels in the non-TRE fasting group (p = 0.0018) and McAllister et al. noted no difference. Dinner-skipping resulted in significantly reduced evening cortisol and non-significantly raised morning cortisol. Conversely, breakfast skipping resulted in significantly reduced morning cortisol. This blunting indicates a dysfunctional HPA axis, and may be associated with poor cardio-metabolic outcomes. There is a paucity of research examining the effects of TRE on cortisol and melatonin. The contrasting effect of dinner and breakfast-skipping should be further examined to ascertain whether timing the feeding window indeed has an impact on circadian rhythmicity.
The Underlying Order Induced by Orthogonality and the Quantum Speed Limit
Authors: Sevilla Francisco J. , Valdés-Hernández Andrea , Barrios Alan J.
Published: July 2021

We perform a comprehensive analysis of the set of parameters {ri} that provide the energy distribution of pure qutrits that evolve towards a distinguishable state at a finite time τ, when evolving under an arbitrary and time-independent Hamiltonian. The orthogonality condition is exactly solved, revealing a non-trivial interrelation between τ and the energy spectrum and allowing the classification of {ri} into families organized in a 2-simplex, δ2. Furthermore, the states determined by {ri} are likewise analyzed according to their quantum-speed limit. Namely, we construct a map that distinguishes those ris in δ2 correspondent to states whose orthogonality time is limited by the Mandelstam–Tamm bound from those restricted by the Margolus–Levitin one. Our results offer a complete characterization of the physical quantities that become relevant in both the preparation and study of the dynamics of three-level states evolving towards orthogonality.

Published: July 2021

Marine geophysical surveys were carried out at the underwater site in the south-western sector of the Eastern Harbor of Alexandria, opposite to the Egyptian Sea Scout Club. Survey works aimed to detect and study the surface and subsurface geomorphological changes caused by historic sea-level rise and natural hazards, by integrating the results of high-resolution geophysical mapping for the seafloor textures and the subsurface layers with previously published core data and sea-level records, the survey works employed echo-sounder, side scan sonar, and sub-bottom profiler. Acoustic data were ground-truthed using an ROV camera and sediment grab sampler. Results of bathymetric mapping and sonar imaging outlined two breakwaters and quay corresponding to a submerged ancient port; also, sediment types were classified according to variation in the magnitude of the backscattered intensities. Interpretation of sub-bottom profiles illustrated the depositional sequence of the topmost sedimentary layers where the sediment thicknesses were thickened by rates that perfectly matched with the recorded sea-level rise rate during the last two millennia, as indicated by isopach maps. Anthropogenic activities were noticed in particular outcropping areas on the sub-bottom profiles. The results explained the role of natural hazards and sea-level rise in changing the geomorphology of the coastline and seabed features.
Middle Pleistocene Variations in the Diet of Equus in the South of France and Its Morphometric Adaptations to Local Environments
Authors: Uzunidis Antigone
Published: July 2021

Equus is a very sensitive genus which has expanded over a large area and lived in Europe despite the climatic instability of the Pleistocene. Its persistence and abundance are helpful in understanding and describing environmental and climatic regional parameters. In this study, we present the result of dental mesowear and microwear analysis and post-cranial skeleton biometry on Equus populations located in two regions in the South of France from ten sites, corresponding to twelve assemblages dated from MIS 12 to MIS 5. The areas refer to two major climatic zones: the oceanic or subcontinental climate for the South West of France, and the Mediterranean for the South East. The first objective of this study is to integrate and compare biometric data, dental wear, and other already-published environmental proxies. The goal is to discuss the validity of horse body shape adaptations on a small geographical scale. The second objective is to describe the impact of environmental features on the horse population through time in the two regions. We observe that the Equus diet was quite diverse, according to microwear analysis which shows adaptations according to seasonal variations. However, they remained mostly grazers over a long period of time. Estimated body mass of Equus in the localities studied here varies from a mean of 468 up to a mean of 570 kg, but these variations failed to be correlated with the diet, the climatic period, or the geographical position of the horse population, probably because of the sample size or the restricted time-span or geographical scale. However, the conformation of the metapodials and the width of the third phalanges may have been linked with environmental and behavioural parameters. The width of the third phalange may be correlated with the recurrence of the snow cover, while the robustness of the metapodial co-occurs with a humid climate. Also, diet may influence the conformation of the bones, since the tall and slender horses seem to be preferentially grazers all year long and seasonally browser horses are tall and robust. Seasonally mixed-feeder horses, all coming from the Mediterranean area, were found to be smaller, perhaps in relation to a less productive environment. The correspondence of the dietary and morphometrical data could suggest high pressure on the horse population, which caused rapid body adaptation. Thus, the combination of these different proxies allows us to suggest more accurate large mammal paleoenvironmental reconstructions.

Published: July 2021

A prospective, multicenter, randomized, sibling oocyte study was conducted with 86 couples to evaluate if a microfluidic sperm separation device improved ICSI sperm selection and subsequent cycle outcomes of fertilization, blastocyst utilization, ploidy, and clinical pregnancy rate when applied to a general patient population. Patients with at least 10 metaphase II oocytes were enrolled in the study and sibling oocyte groups were split in half. One half of the oocytes underwent ICSI with the control processed sperm and the other half were injected with sperm sorted by the ZyMōt microfluidic sperm separation device. Fertilization rate was recorded and resulting blastocysts were biopsied and evaluated for ploidy status with NGS. Euploid, non-mosaic embryos were randomly selected for single embryo transfer. A total of 787 oocytes were evaluated in the ZyMōt group and 777 in the control group. No statistical differences were observed between ZyMōt and control processing methods in any of the study outcomes evaluated. It is possible that the selection of normal, progressive sperm for ICSI, and the repair capacity of oocytes are sufficient to promote normal embryonic development in the general infertility population.

Authors: Auten Abi , Cavey Kristina , Reed Jacob , Dolgener Forrest , Moriarty Terence
Published: July 2021

Background: Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low levels of a constant current via scalp electrodes to specifically targeted areas of the brain. The effects of tDCS on whole-body exercise performance has been of interest in recent literature. The purpose of the current investigation was to investigate if tDCS, administered via Halo Sport, influences time trial performance in trained cyclists, and if changes in exercise performance are associated with prefrontal cortex (PFC) activation and/or muscle oxygenation (SmO2). Methods: Twelve recreationally trained cyclists volunteered to participate in a crossover study design involving two 10-kilometer time trials following 20 min of tDCS or a sham condition. Results: t-tests showed there was no significant difference in performance (time to completion) or physiological measures (blood lactate (BL) concentration, heart rate (HR), SmO2, PFC oxygenation) between the Halo and sham conditions. Conclusions: These results indicate that the application of tDCS via Halo Sport does not induce changes in exercise performance or related physiological parameters during a 10-kilometer cycling time trial.

Published: July 2021

Based on the constant need for safety and operational cost optimization, the air-cargo industry is continually evolving in the context of Industry 4.0. Used wisely, data can help the industry to provide critical resilience that will allow authorities to take proper measures/actions in response to unexpected disasters and secure societal protection. The “INTELLICONT” project combines state-of-the-art technologies blended with novel solutions to improve the loading/unloading time, the structural status awareness, and the safety and security of the air-cargo related operations (prior to, during, and after the flight), as well as to enhance their capabilities related to the execution of their duties. The suggested system is contextually aligned and harmonized with the existing international and EU regulations. In the present work, the remote monitoring and control system for intelligent aircraft cargo containers have been presented from the software perspective. The intelligent containers integrate three types of sensors, Structural Health Monitoring, fire suppression, and locking status indication. The focus has been given to the design and development of a Human Machine Interface (HMI) capable to visualize all related data for better and safer control of the aircraft cargo. It is shown that the system can contribute to making the air transportations safer, environmentally friendlier, faster and with the lowest possible cost.

Gluten-free flour confectionery for school meals
Authors: Kulakov V.G.
Published: July 2021

The priority task in the development of gluten-free flour confectionery products is to ensure the health of children with metabolic disorders that lead to the development of diseases of the gastrointestinal tract and other pathological conditions, which in turn contribute to reducing the child's immunity. Children are the most vulnerable group, for whom nutrition is a factor in the development of all organs and life support systems. Students receive increased mental and physical loads, therefore, the lack of necessary food components negatively affects the development of children. Parents are undoubtedly aware of the role of proper nutrition, especially for children with various diseases of the gastrointestinal tract, but it is extremely important that educational institutions at all levels complement and in some cases completely make up for poor-quality nutrition of the child in the family. All educational institutions have children with metabolic disorders, and these institutions are already working in accordance with the sanitary norms and regulations of the Russian Federation, but the task of the University is to inform such institutions about the need to provide specialized products, including gluten-free ones.
Autoprobiotics for personalized nutrition of school children
Authors: Ganina V.I.
Published: July 2021

According to the Ministry of Health and Social Development of Russia, the health status of children and adolescents in the Russian Federation is characterized by the following indicators: more than half of school-age children have impaired health; two-thirds of children under 14 have chronic diseases; only 10-15 percent of graduates of general education institutions can be classified as healthy. In recent decades, with the development of nutrigenomics, the world community of scientists has come to understand the importance of the role of the microbiota in the human body and its relation with nutrition. Normal intestinal microbiota is involved in a variety of physiological functions of the body of school-age children: protective, digestive, detoxifying and anticarcinogenic, synthetic, genetic, immunogenic, metabolic, and others. Probiotic bacteria are one of the functional ingredients that have proven to have a positive effect on children's bodies. Methods of normoflora correction are proposed, aimed not only at restoring evolutionarily conditioned microbial populations, but also providing an effective impact on the individual organism.

La idea, la política y la vivienda: ruta para ingresar a la crisis neoliberal desde el espacio urbano en Chile
Authors: Hidalgo Dattwyler Rodrigo , Alvarado Peterson Voltaire
Published: July 2021

El presente trabajo propone ingresar a través de rutas distintas para explicar la actual crisis del espacio urbano en Chile. Se exponen elementos teóricos basados en las posibles rupturas del llamado modelo chileno, diseñado en su origen como proyecto hegemónico de la geopolítica bajo la influencia activa de Estados Unidos en Latinoamérica, que pueden aportar al entendimiento de la fragilidad del capitalismo en el subcontinente y dar luces sobre cómo este sistema ha tendido a acumular riqueza de renta rápida y segura en los negocios inmobiliarios. Al mismo tiempo, se ejercitan reflexiones respecto de la Geografía Política para reconocer la construcción de fronteras urbanas nuevas en medio de la transformación de la naturaleza como un valor en-sí. Para ello se consideran dos casos de estudio: La Serena y Valdivia, ambas ciudades de características morfológicas excepcionales, cuyo emplazamiento se dinamizó a partir del juego de posiciones y construcción de fronteras detonados por los procesos de intervención urbana de los siglos XX y XXI. Finalmente, se trabajan las herramientas políticas que permiten al Estado, a partir de los subsidios habitacionales, obliterar las asonadas de crisis, incluso cuando el modelo grita por su salvación.

En este trabajo nos proponemos abordar la dinámica de la figura de Eva Duarte de Perón desde la performance de Martín Marcou y su grupo Teatro Crudo, Evita trans (2012) que intervino dos espacios disímiles tales como el penal de Devoto por un lado y el Centro Cultural Eladia Blázquez. Comprenderemos cómo estas prácticas artísticas se ubican dentro de la definición de lo liminal y recurren a múltiples imaginarios. Para ello, utilizaremos diversos paratextos, entrevistas que les realizamos a algunos de los participantes de la experiencia, así como fotografías y reconstrucciones de la performance realizadas por el  propio dramaturgo de la obra.
Teatro en la provincia argentina de Corrientes: sus historias, devenires y actualidad (2da. Parte)
Authors: González Malala
Published: July 2021

Este trabajo de investigación se propone continuar el estudio sobre la actividad teatral en la provincia argentina de Corrientes, contemplando desde sus orígenes pre-coloniales hasta su devenir en la actualidad reciente (2010). En la primera parte –que fuera publicada en el número anterior de esta revista– abordamos desde un enfoque cronológico ordenador, la sistematización y consolidación del campo teatral y la formación de grupos, y estudiamos aspectos ligados a los espacios teatrales y al público asistente en la ciudad Capital, además de contemplar cruces y coexistencias con el carnaval. En esta segunda parte nos abocaremos a otros aspectos del teatro correntino: la actividad teatral desarrollada dentro de la provincia (tomando algunos ejemplos en la ciudad de Goya, Monte Caseros y Paso de los Libres), notas sobre la dramaturgia regional, el lugar que ha tenido la investigación teatral en la región y, para concluir, nos detendremos en una puesta en escena contemporánea vista durante nuestro trabajo de campo. De esta manera, completaremos la investigación realizada hace algunos años en la provincia mesopotámica, guiándonos por la hipótesis de que en nuestro país la actividad teatral es muy vasta y heterogénea, por lo que cada región merece una atención particular sobre sus respectivas singularidades, escenarios y protagonistas.

"Ethica. Natura e origine della mente": una performance que suspende y triangula luz/cuerpo/mente
Authors: Musitano Adriana
Published: July 2021

Hoy resuena incómoda aquella performance de les Castellucci a la que asistí con muchas otras personas en 2019, porque este ahora de pandemia enlaza tiempos. Y "Ethica. Natura e origine della mente" reclama pensar –desde Spinoza, Romeo y Claudia Castellucci– situándonos en nuestro momento de cortes y cese del movimiento acostumbrado. En este trabajo de concatenar imágenes trataré de no ceder a la gravedad del tema filosófico ni a la incomprensión ante ciertos significantes, o la dificultad que traen las alegorías a las que Romeo Castellucci alude en entrevistas. Esta performance nos desafía, pareciera que hubiese anticipado la experiencia inusual de nuestros cuerpos, los que desde hace más de un año penden en el extenso territorio mundial, con una oscilación entre el escuchar el lenguaje, el aullido, mirar la luz eléctrica, sus parpadeos en la virtualidad de las pantallas y sentir la brutal animalidad de ciertas interacciones. Atrae articular la performance con la traducción de las figuras de la Luz y de la Cámara, triangulando con nuestras incertezas, entre la vida y la muerte. “Si el cuerpo humano ha sido afectado una vez por dos o más cuerpos al mismo tiempo, cuando la mente imagine después luego a uno de ellos, al instante recordará también los otros” (Spinoza, Ética, II, 2020: 133. Cursivas del texto).
Un tríptico de la violencia política en Colombia
Authors: Flórez Meza Jaime
Published: July 2021

En 2014 la compañía colombiana Mapa Teatro estrenó el montaje escénico-visual Los incontados: un tríptico, el cual se presentó hasta 2019 en importantes eventos en Colombia, Brasil y Europa. Este proyecto artístico, que cierra la trilogía Anatomía de la violencia en Colombia que la compañía inició en 2010, enlaza y confronta tres formas en que ha discurrido la violencia política en Colombia desde la segunda mitad del siglo XX: la guerrilla, el narcotráfico y el paramilitarismo.  Un común denominador en ellas es la perturbadora correspondencia entre fiesta y violencia a través de tres regímenes de alteración festiva:  la fiesta-revolución, la fiesta-bonanza y la fiesta-pasión. El montaje muestra así que lo que empieza como una fiesta o una celebración —íntima, privada o pública— puede ser trágicamente alterado por esa violencia política. O que un hecho violento puede revestirse de celebración.
El discurso didascálico. Una tipología revisada
Authors: Zucchi Mariano
Published: July 2021

Las didascalias constituyen, sin dudas, el tipo de enunciado más estudiado por los estudios teatrológicos. Sin embargo, no existe en la actualidad un consenso respecto a las características lingüísticas distintivas de estos discursos ni a su función en el proceso de construcción de sentido. Luego de revisar críticamente las diferentes definiciones que la tradición provee sobre las didascalias, este artículo se propone identificar la naturaleza específica de estas expresiones y sus atributos particulares. Para ello, y frente al reconocimiento de que el discurso didascálico no constituye un conjunto homogéneo de enunciados, se plantea, en primer lugar, la necesidad de establecer una taxonomía que atienda a la diversidad de empleos y de significados que aportan. En ese sentido, se propone aquí distinguir entre las didascalias paratextuales, las estructurales, las generales, las atributivas y las particulares. Mediante la utilización de ejemplos de obras representativas de distintas estéticas teatrales, se explican las propiedades morfo-sintácticas de cada uno de estos subtipos y sus diversas funciones. Finalmente, y en cuanto a la perspectiva de trabajo, se adopta aquí el Enfoque dialógico de la argumentación y la polifonía enunciativa (Caldiz, 2019; García Negroni, 2016a; 2016b; 2018a; 2018b; 2019; García Negroni y Libenson, 2018; 2019).
Para una estética de la danza. Comentario a "Filosofía de la danza" de Paul Valéry
Authors: Granados Valdéz Juan
Published: July 2021

En este trabajo me propongo plantear algunas ideas que aproximen a una estética de la danza a partir del comentario al texto de Paul Valery titulado “Filosofía de la danza”. El destacado lugar que ocupa la danza entre las artes y en la cultura de todos los pueblos es innegable. No obstante, la comprensión de su sentido es aún deficiente en muchos círculos. El recurso a cierto tipo de espectadores, en este caso un filósofo, en diálogo con quienes se dedican profesionalmente a bailar, puede adelantar en dicha comprensión, que ha de llamarse estética, porque la danza, como las otras artes se perciben, se sienten, se imaginan y se piensan.

Fugl Meyer Assessment for Paralytic Glove with Micro Motor Configurations to Assist Post Stroke Therapy
Authors: Arumugam Kalaiarasi , Loganthan Ashok Kumar
Published: July 2021

Today, brain attack disorders are one of the most life-threatening areas in the medical era, which the mankind is facing nowadays. Globally, more than 10, 00,000people are subjected to brain attack disorders like hemiplegia and tremor, every year, where two-thirds of them survive. Among the survival community, more than 80 per cent of them are subjected to long-term impairment of their upper extremity. In order to treat the impairment, the survival group is subjected to medications and rehabilitation in order to improve their daily living. But the facilities are very limited in fast- developing countries like India when compared to western standards. The rehabilitation given in corresponding with medications during the treatment period in hospitals does not give a complete recovery from disability. People from rural background could not meet their rehabilitation requirements even in the hospital during treatment and also when they are discharged to home after treatment from hospitals due to financial constraints and reachability. In order to motivate the survival group to fulfill their daily living and improve their lifestyle, this paper is focused on intelligent home-based rehabilitation system at low cost, reliability, and affordability. One major movement disorder namely Upper Arm Hemiplegia was taken into account and visited few major hospitals around Coimbatore and Chennai for literature and case study. The facilities available in various hospitals and their drawbacks were analyzed. Based on the studies conducted at hospitals and taking advice from therapists, an innovative low-cost home- based rehabilitation device using Electro-Mechanical systems has been developed to support samples who were used to impaired living even after treatments. To support Upper Arm Hemiplegia patients, the devices which were developed and experimented with Fugl Meyer Assessment to analyse the improvements in different functionalities are discussed in this paper.
