Optical Trapping of Chiral Particles by Dual Laser Beams
Authors: Bai Jing , Ge Cheng-Xian , Wu Zhen-Sen
Published: August 2023

In this paper, an analytical method for studying the radiation force (RF) of chiral spheres generated by dual laser beams is presented under the framework of generalized Lorenz–Mie theory (GLMT). According to the coordinate transformation relations, the arbitrarily incident laser beam is represented by vector spherical harmonic functions (VSHFs) in the sphere system. The entire induced field expression coefficients of dual laser beams can be obtained by superposition of each illuminated field. Based on the momentum conservation theory, the concrete expression of lateral and axial RF on chiral sphere is derived. The current theories are shown to be valid by comparison with the existing reference. To investigate the stable capture state of chiral sphere, the influences of the corresponding parameters of chiral particles and dual laser beams on the trapping and manipulation are investigated in detail. The analytical study on the RF of dual laser beams on chiral particles is an efficient method for improving optical tweezers technology and can become an encouraging approach to realize the high accuracy operation of chiral particles.
Terahertz Humidity Sensing Based on Surface-Modified Polymer Mesh Membranes with Photografting PEGMA Brush
Authors: You Borwen , Huang Chih-Feng , Lu Ja-Yu
Published: August 2023

A simple and compact intensity-interrogated terahertz (THz) relative humidity (RH) sensing platform is successfully demonstrated in experiments on the basis of combining a porous polymer sensing membrane and a continuous THz electronic system. The RH-sensing membrane is fabricated by surface modification of a porous polymer substrate with hydrophilic and photosensitive copolymer brushes via a UV-induced graft-polymerization process. The intensity interrogation sensing scheme indicated that the power reduction of the 0.4 THz wave is dependent on the grafting density of the copolymer brushes and proportional to the RH percent levels in the humidity-controlled air-sealed chamber. This finding was verified by the water contact angle measurement. Based on the slope of the proportional relation, the best sensitivity of the hydrophilic surface-modified sensing membrane was demonstrated at 0.0423 mV/% RH at the copolymer brush density of 1.57 mg/mm3 grafted on the single side of the sensing membrane. The sensitivity corresponds to a detection limit of approximately 1% RH. The THz RH sensing membrane was proven to exhibit the advantages of low loss, low cost, flexibility, high sensitivity, high RH resolution, and a wide RH working range of 25–99%. Thus, it is a good candidate for novel applications of wearable electronics, water- or moisture-related industrial and bio-sensing.
First Law Optimization and Review of Double and Triple-Effect Parallel Flow Vapor Absorption Refrigeration Systems
Authors: Azhar Md.
Published: August 2023

Parallel flow double and triple-effect vapor absorption cooling systems (VACS) are trying to meet the challenges of vapor compression cooling systems due to their better performance. Therefore, the present study deals with the review, thermodynamic analysis, and optimization of operating parameters for both double and triple-effect VACS. Lithium bromide water was selected as the working fluid, while liquified petroleum gas (LPG) and compressed natural gas (CNG) were taken as the source of energy to drive both the VACS. Detailed First Law analysis, i.e., coefficient of performance (COP), was examined along with the optimization of operating parameters (such as salt concentration and operating generators temperature at different pressure levels) and the volume flow rate of the gases. Optimization was carried out for maximum COP of the VACS using an iterative technique. Our results show that the COP of the triple-effect system was approximately 32% higher than the double effect, while 15–20% less consumption of the gases (LPG and CNG) was observed. The most optimum stage for the operation of triple-effect VACS was reached at Te = 4 °C and Tc = Ta = 30 °C, Tg = 180 °C, Tc4 = 104 °C, Tc3 = 66 °C, Z1 = 0.5, and Z2 = 0.45.
Counting Abalone with High Precision Using YOLOv3 and DeepSORT
Authors: Kibet Duncan , Shin Jong-Ho
Published: August 2023

In this research work, an approach using You Only Look Once version three (YOLOv3)-TensorFlow for abalone detection and Deep Simple Online Real-time Tracking (DeepSORT) for abalone tracking in conveyor belt systems is proposed. The conveyor belt system works in coordination with the cameras used to detect abalones. Considering the computational effectiveness and improved detection algorithms, this proposal is promising compared to the previously proposed methods. Some of these methods have low effectiveness and accuracy, and they provide an incorrect counting rate because some of the abalones tend to entangle, resulting in counting two or more abalones as one. Conducting detection and tracking research is crucial to achieve modern solutions for small- and large-scale fishing industries that enable them to accomplish higher automation, non-invasiveness, and low cost. This study is based on the development and improvement of counting analysis tools for automation in the fishing industry. This enhances agility and generates more income without the cost created by inaccuracy.
Insight into the Physicochemical Properties of Co-Based Catalysts in Fischer–Tropsch Synthesis
Authors: Shiba Nothando C. , Liu Xinying , Yao Yali
Published: August 2023

The effect of the different supports and catalyst-reducing agents on the Fischer–Tropsch (FT) reaction was investigated. The large surface area SiO2 support with a smaller pore volume deposited fine, evenly distributed Co3O4. Cubic-shaped Co3O4 appeared in clusters on the TiO2 support, whereas Co3O4 existed as single large particles on the Al2O3 support. The activity data obtained were discussed in terms of cluster size, particle size, particle shape, and mass transport limitations. The SiO2-supported catalysts showed a higher activity for the formation of paraffinic products when reduced in H2 at 250 °C. This is attributed to the formation of the CoO-Co active bond, which enhanced the activation of CO and the hydrogenation reactions. A higher activity was observed for the TiO2-supported catalyst at a higher reduction temperature (350 °C) when the mass of Co metal was higher. It afforded more paraffinic products due to enhanced secondary hydrogenation of olefins at higher reaction rates. The large Co3O4 supported on Al2O3 showed the least activity at both reduction temperatures due to strong metal-support interactions. The H2-reduced catalysts exhibited superior activity compared to all the syngas-reduced catalysts. Syngas reduction led to surface carbon deposition and the formation of surface carbides which suppressed the hydrogenation reactions and are selective to olefinic products.
Inshore Ship Detection Based on Multi-Modality Saliency for Synthetic Aperture Radar Images
Authors: Chen Zhe , Ding Zhiquan , Zhang Xiaoling , Wang Xiaoting , Zhou Yuanyuan
Published: August 2023

Synthetic aperture radar (SAR) ship detection is of significant importance in military and commercial applications. However, a high similarity in intensity and spatial distribution of scattering characteristics between the ship target and harbor facilities, along with a fuzzy sea-land boundary due to the strong speckle noise, result in a low detection accuracy and high false alarm rate for SAR ship detection with complex inshore scenes. In this paper, a new inshore ship detection method based on multi-modality saliency is proposed to overcome these challenges. Four saliency maps are established from different perspectives: an ocean-buffer saliency map (OBSM) outlining more accurate coastline under speckle noises; a local stability saliency map (LSSM) addressing pixel spatial distribution; a super-pixel saliency map (SPSM) extracting critical region-based features for inshore ship detection; and an intensity saliency map (ISM) to highlight target pixels with intensity distribution. By combining these saliency maps, ship targets in complex inshore scenes can be successfully detected. The method provides a novel interdisciplinary perspective (surface metrology) for SAR image segmentation, discovers the difference in spatial characteristics of SAR image elements, and proposes a novel robust CFAR procedure for background clutter fitting. Experiments on a public SAR ship detection dataset (SSDD) shows that our method achieves excellent detection performance, with a low false alarm rate, in offshore scenes, inshore scenes, inshore scenes with confusing metallic port facilities, and large-scale scenes. The results outperform several widely used methods, such as CFAR-based methods and super-pixel methods.
A Parametric BIM Framework to Conceptual Structural Design for Assessing the Embodied Environmental Impact
Authors: Ajtayné Károlyfi Kitti , Szép János
Published: August 2023

Decisions made in the early design stage have a significant effect on a building’s performance and environmental impact. In practice, a conceptual design is performed by an architect, while a structural engineer begins to work in later phases when the architectural concept has already evolved. However, the geometry and form of a building directly determine the type of structure and applicable materials; therefore, the conceptual design phase gives rise to examining alternative solutions. This paper presents a method for generating alternative structural solutions in the conceptual design phase and examining their embodied environmental impact by integrating parametric design and building information modeling (BIM). Rhinoceros and Grasshopper were used to develop the parametric script, which includes the generation of geometrical variations, the automatic definition of initial cross sections for the load-bearing elements based on in-built structural design approximations, the datasets for embodied environmental impact of the used building materials, the generation of life cycle inventory (LCI), the automatic calculation of life cycle assessment (LCA) results based on the geometry, and the conversion of the parametric model into building information model. The method was demonstrated using a case study of 48 different alternative solutions for an unheated warehouse made of steel frames. Based on the results, the areas with the greatest energy impact were identified. The case study analysis also illustrated that the applied cross section may have a significant effect on the impact categories. The results draw attention to the complexity of LCA calculations even in the case of a simple structure containing a limited number of variables, where parametric design can serve as an effective tool for a comprehensive environmental impact assessment.

Published: August 2023

Large quantities of second-hand clothing have been exported from the Global North to the Global South in recent decades, placing a heavy social and environmental burden on local communities. Consequently, countries in the Global South are leveraging indigenous craftsmanship through various practices, such as care, repair, and upcycling, to enable durability and extend product life, saving millions of garments from landfills. However, this knowledge is not included in global narratives on durability and the circular economy. Moreover, the Global North dominates the conversation, often leaving out the social dimension and risking a circular transition from achieving important goals such as decent jobs to reducing the unequal distribution of negative environmental and social impacts. This study examines the trinary interrelationship between circularity, garment durability, and just transition through an integrative literature review. The review revealed several key findings. Firstly, the authors posit that garment durability is an ongoing interaction between the garment and its changing environment(s) and user(s), enabling it to move through different life cycles via the practices of care, mending, and repair. Secondly, all three concepts must place people at the heart of the fashion industry to ensure a just and circular transition.

This paper employs a knowledge mapping approach to scientifically and intuitively demonstrate research on the road safety issues of ICV over the last decade. By utilizing bibliometric tools such as CiteSpace, VOSviewer, and SciMAT, a total of 3661 original articles from the Web of Science are examined to explore three aspects. Firstly, the study investigates the collaborative relationships among authors and institutions within the industry. Secondly, it summarizes major research topics by analyzing and clustering keywords. Lastly, the paper identifies research hotspots and predicts future research directions. The findings reveal a dynamic field characterized by close collaboration among diverse institutions, with China and the United States emerging as the most active countries and mathematics and computer science journals becoming mainstream. According to three bibliometric tools, the research topics primarily revolve around three areas: Vehicular ad hoc Networks (VANET), intelligent transportation systems (ITS), and network security. Machine learning and V2X communication are predicted to be essential research topics in the next stage. Research on traffic accidents still has potential as the number of ICVs increases.
Use Case of Water Reservoir Protection as a Critical Infrastructure Element in Slovakia Using a Quantitative Approach
Authors: Loveček Tomáš , Mariš Ladislav , Petrlová Katarína
Published: August 2023

Water management systems play a crucial role in efficiently allocating water resources while taking into account various demands such as agriculture, industry, domestic use, and environmental needs. These systems optimize the distribution of water, ensuring fair access and minimizing water scarcity and conflicts. However, these critical systems are vulnerable to different types of attacks. Depending on the target, these attacks can take the form of physical, cyber, or combined assaults. The protection requirements for water objects, which are integral to critical infrastructure, are primarily defined by legal regulations, technical standards, and other third party requirements. These requirements necessitate the implementation of protective measures. One effective approach to implementing protective measures is through a physical protection system (PPS), which prevents unauthorized individuals from achieving their objectives. The current procedures for protecting these objects can be based on either a qualitative or quantitative approach. In this article, we present a use case that demonstrates a possible method for protecting a specific water reservoir, identified as a national element of critical infrastructure in the Drinking Water Provision subsector. The use case involves analyzing security requirements and designing a PPS for the water reservoir. To assess the effectiveness of the proposed PPS, a quantitative PPS model was developed using specialized software. Additionally, four potential attack scenarios were simulated to verify the functionality of the PPS.

Published: August 2023

Pulse flow, which includes base flow, peak flow, flow duration, occurrence time, and frequency, is a manifestation of environmental flow in rivers. This paper describes a methodological framework for determining pulse flow based on an analysis of fish spawning behavior and presents its application to the second Songhua River in northeastern China. Peak flow was determined based on the hydrographic-habitat relationship for fish spawning in conjunction with physical habitat simulation. The flow duration was determined based on the incubation period of fish eggs. The occurrence time and frequency were determined based on the suitable temperature for fish spawning. This application differs from conventional methods for dividing fish spawning periods and selecting target species in the corresponding period. Fish were divided into cold-water fish, hypothermal-water fish, and warm-water fish according to spawning temperature, and the target species in each month of the spawning period (April to July) were identified. For the same spawning period, the hydrographic-habitat relationships of target species with adhesive and drifting eggs were weighted to determine the peak flow. The most suitable peak flow for fish spawning from April to May in the research region is 900 m3/s and 1200 m3/s for June to July. Using the proposed framework, an ecological hydrograph from April to July was obtained by combining the method of pulse flow with habitat simulation. Fifteen days, eight days, and five days were chosen as the flow durations for April, May, and June to July, respectively. We recommend scheduling two high pulse flows each month from May to July while limiting the occurrence to only one in April. The results show that this framework offers a promising approach for developing environmental flows in rivers with a variety of fish species.

Authors: Zhang Yuewen , Liu Peirui , Hong Yu
Published: August 2023

Harmful algal blooms are a global problem in water environments, and their explosive growth endangers the health of aquatic ecosystems. Magnetic nanomaterials for the harvesting of microalgae have received a lot of attention because of their high efficiency, low cost, and ease of operation. In this study, magnetic mesoporous silica nanomaterials were prepared using Fe3O4 as a carrier and harvesting on Chlorella sp. HQ. It was found that silica coated with magnetic Fe3O4 microspheres has good dispersion. The harvesting of Chlorella sp. HQ via magnetic mesoporous silica could be maintained over a wide pH range (4 to 12). After the removal of organic components from the surface of the material, the magnetic mesoporous silica obtained a better porous structure. The ethanol reflux method was more beneficial than the calcination method in maintaining the stable structure of the material, thus improving the harvesting efficiency of the material for the microalgae Chlorella sp. HQ by a maximum of 17.8% (65.9% to 83.7%). When the molar ratio of active agent cetyltrimethylammonium bromide (CTAB) and stabilizer polyvinylpyrrolidone (PVP) was 1: 0.092 at pH 4 and algal concentration of 0.5 g/L, the materials showed the maximum harvesting efficiency of Chlorella sp. HQ was 84.2%.

Biofuel production is a renewable energy resource that is not only the most stabilized source of energy but also one of the sustainable alternatives to non-renewable-sourced fuels. Microalgal biomass is emerging as a third-generation biofuel owing to its high lipid content. The specific biomass concentration and lipid content are responsible for direct biodiesel production. Computational Fluid Dynamics (C.F.D.) studies are gaining importance due to the luxury of exploration without requiring a considerable capital cost. The microalgal strains of Chlorella sorokiniana have shown the maximum specific growth rate of 0.11 h−1 among several algal species and contain 19% w w−1 lipid. Characterization reveals that the lipid content is suitable for biodiesel production. CO2 sequestration, biodiesel production, and secondary metabolites by green algae, C. sorokiniana, are reported in this work. A C.F.D. study is also being conducted for the flat-panel photobioreactor.

The aim of the study was to identify the relationship between clinical and neurophysiological parameters in patients with non-traumatic supratentorial hematomas. We examined 90 patients in acute period of parenchymal hemorrhagic stroke; the Glasgow Coma Scale (at first day) and the NIHSS (at 1st, 3rd, and 14th days) were used for the assessment of clinical dynamics. Two groups of patients were identified by means of cluster analysis. Cluster 1 included the patients with lower number of correlations between neurophysiologic parameters; cluster 2 included the patients with higher level of conjugacy in the mechanisms of nervous regulation. The clinical and neurophysiological correlations that differed between the groups of the patients were found. The role of EEG slow-wave activity and its association with the severity of neurological symptoms in the group of the patients with regress of neurological deficit were described. The role of desynchronizing influences in minimizing the severity of neurological deficit in patients with unfavorable course of disease was established. In conclusion, we emphasize the heterogeneity of the groups of the patients with parenchymal hemorrhagic stroke due to their clinical course; the role of synchronizing and desynchronizing influences of the brainstem structures according to EEG data in the assessment of the course of acute period of hemorrhagic stroke is highlighted.

The Mars as the Parent Body of CI Carbonaceous Chondrites Hypothesis Re-Examined in the Light of New Data
Authors: Brandenburg J. E.
Published: August 2023

It had been proposed that the parent body for the CI carbonaceous was the planet Mars. New data strongly supports this hypothesis. The recovery of CI-like material from the asteroid Ryugu, which orbits near Mars has confirmed the importance of CI material as a source of water for the terrestrial planets. The oxygen isotope makeup of the CI is now seen to overlap the distribution of data from the aqueously altered portions of recognized MMs (Mars Meteorites).The CI consist of completely aqueous altered ferro-magnesian silicates, carbonates and sulfates. The physical conditions that produced these materials match conditions on Early Mars, as inferred from portions of recognized ancient Mars meteorites ALH84001and NWA 7533. Noble and Nitrogen gas isotopes match early Mars atmosphere, especially in N, Kr, Xe, and Ar isotopes with a Mars early atmosphere being composed of Chondritic Xe and Kr. The CI, despite early aqueous alteration, appear to have been, like Chassigny, preserved in a hot dry environment and have preserved entrapped Early Mars atmosphere. The CI can thus be considered to be aqueously altered remnants of a late accretion veneer that largely experienced no melt processing. Portions of this lithology have been thermally altered and formed the CY group. This Mars -CI hypothesis can be tested by chronologies of thermal alteration of the CYs .The CI are rich in organic matter, indicating that Early Mars was warm, wet, and rich in the chemical precursors of life and therefore emulated conditions that fostered life on Early Earth.
La existencia dolorosa del héroe trágico. Reflexiones sobre Arturo Borda
Authors: Arce Hochkofler Fernando
Published: August 2023

El autor explora el dilema moral que confronta el hombre agobiado por su sensibilidad de artista, ante una sociedad incapaz de ver su propia miseria. El artista, o se ajusta a los cánones estéticos convencionales o retrata su sociedad sin que ésta se percate, vaciando la significación convencional del lenguaje y recuperando su originalidad inocente. Renunciar al sentido común y salirse de lo general es una rebelión contra el Padre, señala Freud, y es el recorrido del héroe. Pero desde Lacan, Borda se rebela contra la significación del Otro del Padre, para restituir el poder de la palabra plena. El héroe, despojado de su yo imaginario y del sentido común, toma conciencia de su infinitud. En ese momento, según Kierkegaard, o abraza esa conciencia infinita y hace de ella todo su amor (es el movimiento de la fe) o, al percibir el absurdo de la dolorosa existencia humana y la indolencia de un Dios-Padre incognoscible, mata a ese Padre y asume para sí el dolor del prójimo. Es la elección del héroe trágico.
El monstruo pictórico-poético: insurrección y vanguardia en Luis Luksic
Authors: Verdesoto Ardaya Fernanda
Published: August 2023

Investigación enfocada en la primera etapa poética del poeta, pintor, cuenta cuentos, titiritero y militante político boliviano Luis Luksic (Potosí, 1911-Caracas, 1988). El objetivo es relacionar los poemarios Cantos de la ciudad y el mundo (1948) y Cuatro poemas y ocho dibujos (1958), con el arte pictórico generado por Luksic en ese periodo de su producción artística. La pintura de Luksic (que comprende desde obras individuales hasta ilustraciones de libros y portadas de discos), correlacionada con la poética, muestra que la vanguardia es una crisis que no se resuelve, pero que se alimenta desde la hibridación entre contrarios, y así derrumba todo orden y parámetros. La investigación muestra que en la vanguardia existe un “monstruo” de dos cabezas: la revolución política-grupalcomunitaria- colorida y la revolución política-personal-psicológica-surrealista.

De la verdad al poder. Filosofía y política en dos pensadores cruceños
Authors: Fernández García Enrique
Published: August 2023

Procurando aportar a la historia de las ideas en Santa Cruz, el ensayo reflexiona sobre dos pensadores. Así, por un lado, se toma en cuenta la obra y trascendencia de Manfredo Kempff Mercado, el filósofo cruceño más importante del siglo XX, un autor que, pese a morir hace casi 50 años y, además, tener una vida breve, continúa siendo citado por especialistas del pensamiento latinoamericano. Por otra parte, se considera el aporte intelectual de Sergio Antelo Gutiérrez, cuyos artículos y libros fueron significativos para, comenzando esta centuria, discutir sobre la viabilidad del orden estatal. En ambos casos, cabe resaltar el ejercicio de la razón crítica.
Santa Cruz: el nuevo epicentro de la política en Bolivia 2001- 2020, pero no del poder
Authors: Peralta Beltrán José Orlando
Published: August 2023

En Santa Cruz las interacciones políticas ciudadanas han demandado al Estado central, mediante una práctica discursiva liberal (modelo de desarrollo) y republicana (participación), respeto a la identidad regional y reglas de juego (21f), autonomía departamental y transparencia electoral. Sin embargo, el uso de aquel discurso no se ha materializado en un proyecto de poder interdepartamental. El objetivo es distinguir los contenidos ideológicos de dicha práctica social en relación con el discurso nacional-popular predominante. Se concluye que ningún actor político cruceño ha podido traducir las interacciones políticas y creencias ideológicas en clave regional en una práctica discursiva en clave nacional.

El objetivo de este trabajo es analizar el fenómeno de convergencia para los municipios de Santa Cruz durante el periodo 1992-2012, que coincide con el de aplicación de la ley de Participación Popular, usando el Índice de Necesidades Básicas Insatisfechas como variable “proxy” para pobreza.
Las Misiones Jesuíticas de Chiquitos, Patrimonio de la Humanidad: descubrimiento y resurrección
Authors: Kühne Eckart
Published: August 2023

Las Misiones Jesuitas de Chiquitos en las tierras bajas de Bolivia se inscribieron en 1990 en la lista del patrimonio mundial de la Unesco, pero hasta alrededor de 1950, el patrimonio cultural de estos pueblos quedó casi totalmente desconocido, tanto para los bolivianos en general, como para los científicos especializados. Gracias a que el jesuita suizo Martín Schmid, estando en su tierra natal, se acordó de éstas, fue posible iniciar desde 1972 un programa de restauración de sus iglesias dirigido por el arquitecto suizo Hans Roth, lo que desencadenó la reanimación de la herencia chiquitana tangible e intangible, hasta llegar a formar parte de la identidad cultural cruceña. El artículo cuenta la historia de la creación, supervivencia, descubrimiento y resurrección del patrimonio de Chiquitos, con un enfoque especial del aporte suizo a este proceso.
La novela cruceña en los últimos 75 años: características e identidad en la narrativa oriental
Authors: Hollweg Urizar Karin Gabriela
Published: August 2023

La literatura cruceña, desde sus inicios, tuvo difusión local y poco diálogo con la literatura nacional, respondiendo a la poca integración entre Santa Cruz y el eje económico y político boliviano. Esa lejanía generó en los escritores cruceños una tendencia a relatar su entorno, costumbres y formas de concebir el mundo. A pesar de que la situación cambió y Santa Cruz está ahora mucho más vinculada con las esferas de poder, la novela cruceña aún trabaja sus problemáticas. Analizar la novela cruceña de los últimos 75 años nos permite conocer cómo sus autores han desarrollado una identidad literaria propia.
Reescribir el mito de Asterión desde el horror contemporáneo. Acercamiento a “Sacrificios” de María Fernanda Ampuero
Authors: Cruz-Polo Evelin
Published: August 2023

En medio de un notable desarrollo y visibilización de la literatura ecuatoriana actual, la propuesta de María Fernanda Ampuero se posiciona como referente de lectura ineludible. Las constantes temáticas que identifican su escritura -condición humana ultrajada, lo monstruoso, lo abyecto de la familia y las prácticas religiosas, entre otras- tienden a resignificar el ámbito de lo cotidiano, aspecto que se reafirma en su antología de cuentos Sacrificios humanos, publicada en 2021. El texto, cuya condición genérica se inscribe en el llamado neogótico latinoamericano, articula, a través de doce relatos, una pluralidad de miradas en torno a la noción de sacrificio, de este modo la dupla violencia- muerte se torna eje que dinamiza cada estructura diegética. Por tanto, este trabajo centra su atención en el noveno cuento titulado “Sacrificios” para el que se propone, en tanto hipótesis, una construcción de sentido determinada por la recuperación del mito de Asterión, a partir del cual se destacan las estructuras laberínticas -espacial y discursiva- como dispositivos de encierro y sacrificio. En esta línea, se establece un funcionamiento de correspondencia entre el espacio que se transita y el discurso de los personajes cuya deriva es el horror.
De aduanas y contrabandos: “textos diseminados” en la contemporaneidad latinoamericana
Authors: González Almada Magdalena 
Published: August 2023

Este artículo propone analizar algunas escrituras que atraviesan las subjetividades contemporáneas en relación a problemáticas que se materializan en dos componentes indefectiblemente relacionados: la lengua y el territorio. Las producciones literarias de Emma Villazón (Bolivia, 1983-2015) y de Fabián Severo (Uruguay, 1981) exponen algunos límites del sistema de administración territorial de los Estados-nación siempre dispuestos a establecer bordes -territoriales, lingüísticos entre los que interesan a este trabajo- que resultan cuestionados por poéticas singulares. En ese sentido, nociones como las de frontera y migración serán convocadas en este trabajo a los fines de analizar las escrituras de Villazón y Severo.
Los cánones de belleza
Authors: Pérez Sharon 
Published: August 2023

Los cánones de belleza, ya establecidos en la sociedad desde hace siglos, poco o casi nada se han modificado. A lo largo de los años siempre ha predominado una idea desde la belleza hegemónica blanca. Desde los parámetros europeos, claramente tenemos un ideal de belleza que se basa en proporciones que generalizan y condicionan la manera en la que debemos ver al mundo, donde los colores de piel y los cuerpos de proporciones diversas más voluptuosos o más delgados no son permitidos. Todo esto lo vemos constantemente en la información de comerciales, la música, el cine, el teatro y el arte, materiales que consumimos constantemente y que refuerzan dichos estereotipos.
