fenomenología de la maternidad de Lucía Piossek Prebisch
Authors: Smaldone Mariana , Kretschel Verónica
Published: December 2023

Buscamos aquí explicitar los desarrollos en torno al tema de la maternidad y de la gestación de la filósofa argentina Lucía Piossek Prebisch a partir de su escrito: “Aislamiento y comunicación…” (1966), en términos de una fenomenología de la maternidad. Nuestro objetivo consiste en rastrear varias presentaciones sobre esta temática realizadas por la filósofa y posteriormente publicadas entre los años 1960 y 1980 y hasta 2015, destacando las implicancias conceptuales en sus escritos, el vínculo con la fenomenología y las continuaciones que permitiría su pensamiento. En este sentido, nuestra hipótesis es que las tesis de Piossek Prebisch constituyen un antecedente fundamental dentro del campo de la fenomenología de la maternidad, no solo por lo temprano de su aparición, sino, y sobre todo, por la profundidad y originalidad de su pensamiento.
Espacio-aliento y Espacio cualquiera
Authors: Matti Felipe
Published: December 2023

En este trabajo se analizarán las nociones de “Espacio aliento” y “Espacio cualquiera” desarrolladas por el filósofo francés Gilles Deleuze (1925-1995) en Cine I: La imagen-movimiento, Cine II: La imagen-tiempo y en sus lecciones de Cine dictadas en la Universidad de Vicennes entre 1982 y 1984. La hipótesis principal es que estos espacios tienen la característica de ser pro-nominales, puesto que las personas se desintegran en ellos, perdiendo si individualidad, luego de un proceso de absorción e interacción con la atmósfera del mismo. Esta desterritorialización sería análoga a aquella del paisaje pictórico, debido a lo cual un análisis de los espacios cualesquiera y espacios-aliento es pertinente para abordar la estética deleuziana.
Gallium and Germanium in Pennsylvanian Coals, Shales, and Paleosols in Indiana
Authors: Mastalerz Maria , Roden Nathan
Published: December 2023

Gallium (Ga) and germanium (Ge) are two elements of high industrial interest, included in the current United States and European Union lists of critical raw materials. This paper compares Ga and Ge concentrations between coals and associated paleosols and shales in Indiana. In addition, we include Ga and Ge data on the coal waste from coal preparation plants (coal tailings) to evaluate the coal tailings as potential sources of these elements.
Paleosols have an average Ga content of 26.70 ppm, more than shales with an 18.77 ppm average, and coals with a 4.61 ppm average. The Springfield coal tailings average 15.60 ppm of Ga and the Brazil and Staunton Formation coal tailings average 31.90 ppm. For Ge, the coals have the highest average concentration (6.46 ppm), then shales (1.36 ppm), and paleosols (0.96 ppm). In coal tailings, the average Ge concentration is 13.90 ppm for the Springfield and 47.70 ppm for the Brazil and Staunton Formation coal waste.
For Ga, a very strong positive correlation was obtained with aluminum (Al) in paleosols (R2=0.89) and coal tailings. A strong correlation was also obtained for shales (R2=0.86), together indicating that Al content is a great predictor of Ga concentrations in these materials. For Ge, there seems to be a tendency of decreasing Ge concentration with an increase in Al content in coals, suggesting an organic and not mineral association for this element. The organic association is also supported by a strong negative correlation between Ge and ash yield in coal tailings.

The Mediating Role of Resource Availability and Allocation in Strengthening the Relationship of Change Strategies in the Growth and Development of Entrepreneurial Projects after Covid 19
Authors: Ismael Goran Y.
Published: December 2023

With limited contemporary examinations investigating interactions between change management strategies and startups and entrepreneurial ventures’ growth and development, judgements are bound to be clouded. As a result, the study’s main objective is to identify the key challenges faced by startups and entrepreneurial ventures in response to the post-pandemic business landscape. The study is important for providing valuable insights into successful change management practices, offering practical recommendations for business leaders, and contributing to the understanding of post-pandemic resilience and adaptation in the region’s entrepreneurial ecosystem. The study formulated 8 hypotheses linking digital transformation, customer-centric, financial restructuring and resource optimization, and resource availability and allocation change management approaches with the growth and development of startups and entrepreneurial ventures. A quantitative method involving a Structural Equation Modelling approach was applied to 326 clustered survey responses collected from CEOs, general managers, finance managers, human resources managers, change management leaders and employees and team members of start-ups and entrepreneurial ventures in Erbil, Kurdistan Region of Iraq. According to the findings, digital transformation significantly enhances resource availability and allocation, and growth and development. While customer-centricity may not directly affect resource availability and allocation post-Covid-19, the study concludes that a customer-centric mindset and strategy remain critical to business resilience. Most importantly, financial restructuring and resource optimization positively and significantly affect resource availability and allocation, as well as growth and development. Lastly, the study upholds that resource availability and allocation’s mediating effects are not valid within the context of startups and entrepreneurial ventures in the post-pandemic business landscape.

Svenska generiska pronomen hos finska språkbadselever. En jämförelse mellan två årskurser
Authors: Nyqvist Eeva-Liisa , Lindström Tiedemann Therese
Published: December 2023

This is a study of the use of generic pronouns in Swedish as a second language (L2) by L1 Finnish immersion students. We compare two groups, 12-year-olds, and 15-year-olds, to see if there is a difference and to identify which the most challenging cases are in both groups. Norm deviations are compared to see if they mainly consist of overuse of generic pronouns or more formal aspects, such as the pronoun which is chosen, and the understanding of the relation between the generic subject, object, possessive and reflexive pronouns. Both groups use generic pronouns in the subject position in a manner which mostly follows the standard, and mainly have problems with possessive pronouns in connection to generic pronouns. It is possible that object generic pronouns would also be problematic, but there are none in our data. Generic pronouns are sometimes left out as subjects, which is ungrammatical in Swedish. There is also occasional overuse of man where it is not idiomatic, and some mixed forms with man and s-passive. Results show possible transfer from the first language (L1) of the learners, but less in the older group. Furthermore, there also appears to be transfer from L3 English, which our informants are learning at school. This seems more present in the older group.
Perturbation methods for nonlinear eigenvalue problems
Authors: Fernandes Flávia Gonçalves , Purcina Alcione Borges , Rabelo Luciana Vale Silva , Rabelo Marcos Napoleão
Published: December 2023

In this paper, the dynamics of a microbeam is investigated from the point of view of nonlinear oscillations. Because it regards a non-linear problem, the natural frequency is more complex to obtain. Phenomena such as bifurcations and doubling periods, common in nonlinear systems, may appear. To carry out the ongoing analysis, two components are necessary: first, the equations of motion and, second, the techniques for investigating the behavior of the system. With respect to the equations of motion, deformation gradient theory is used. Concerning the second component, the following approach is employed: techniques of perturbation methods due to the non-linearities present in the model, with the objective of analyzing its oscillations. The important contribution of this investigation resides in a new approach to the equations of motion originated from the formulation of deformation gradient for the context of beams. For future research, it is intended to propose a new stiffness matrix. In the section of computational experiments, results that simulate the behavior of the eigenvalues, eigenfunctions, and solutions of the equation of motion are presented.

The low temperatures found in subsea water combined with the transport of hydrocarbons in flowlines that are immersed in this environment brings the problem of solid deposition inside the flowlines, mainly of paraffin and hydrates, which consists of considerable problems to the petroleum industry. To overcome this issue, computational simulation might be an ally. However, such simulations sometimes can be computationally demanded, making their use unpractical. In these cases, metamodels, which are computationally cheaper models, can be an alternative. The present paper proposes using an Echo State Network as a surrogate model for the problem of stagnant production fluid cooling in a subsea pipe-in-pipe system with active electric heating. The implemented metamodel shows to be twenty-four times faster than the Finite Volume Method, although it showed consistent correlations for all lags when a residual autocorrelation analysis was performed.
O método de escalas múltiplas aplicado a um modelo do oscilador harmônico linear regularmente perturbado
Authors: Machado da Silva Douglas , Pérez-Fernández Leslie D. , Molter Alexandre , Bravo Castillero Julián
Published: December 2023

Métodos de perturbação têm como finalidade obter uma solução aproximada de problemas envolvendo um parâmetro pequeno . Isto é feito decompondo o problema original em uma sequência recorrente de problemas mais simples, a partir dos quais se constrói uma solução assintótica formal (SAF) do problema. No entanto, há problemas para os quais métodos tradicionais da teoria de perturbação não fornecem resultados satisfatórios. Esse fato é ilustrado aqui para o problema do oscilador harmônico linear regularmente perturbado. Para esse problema, como abordagem alternativa, emprega-se aqui o método das escalas múltiplas para construir uma SAF que é uma boa aproximação da solução exata.

Published: December 2023

Neste estudo foi desenvolvido uma análise teórica do modelo de biotransferência de calor de Pennes, cuja região estudada foi um órgão humano diagnosticado com câncer, mais especificamente câncer renal, onde utilizou-se um método minimamente invasivo de ablação térmica com variação da condutividade elétrica para o tratamento deste. Para essa finalidade foi simulado um gerador de radiofrequência para a necrose coagulativa de células cancerígenas como fonte de calor para o modelo empregado de biotransferência. O software MATLAB, foi utilizado para a realização das simulações numéricas por meio da ferramenta pdepe, obtendo-se resultados para um modelo com o valor da condutividade elétrica fixa, σ (0,34 S/m) e um modelo com a condutividade elétrica variável, σ (0,34 a 0,51 S/m) de acordo com a temperatura, com o intuito de demonstrar a importância deste parâmetro na simulação em tecidos vivos. Portanto, pôde-se observar a influência da condutividade elétrica em tratamentos térmicos para tratamentos de diferentes doenças, sem causar maiores danos na vizinhança dos tecidos e órgãos não comprometidos.

Published: December 2023

Este estudo utilizou modelagem computacional para realizar uma avaliação geométrica com base no método Design Construtal em placas de aço com duas perfurações elípticas submetidas à flambagem elasto-plástica biaxial. Mantendo constante o volume de material das placas perfuradas, foram comparados os piores e melhores resultados entre placas com uma e duas perfurações. Para tanto, foi adotada uma placa de referência retangular sem perfurações, da qual uma parcela de material foi removida pela inserção de perfurações elípticas. O parâmetro f, que representa a razão entre o volume das perfurações e o volume do material da placa de referência, foi adotado com valor  = 0,15. Cada placa com duas perfurações foi submetida a cargas compressivas biaxiais, e então foi avaliada a influência que a relação das dimensões das perfurações tem na tensão última de flambagem normalizada. Os resultados mostraram que a melhor configuração geométrica, entre as geometrias analisadas com duas perfurações, é a que possui relação de lados das perfurações igual a 0,6, conduzindo ao aumento de 24,9% na tensão última de flambagem e melhor distribuição das tensões, quando comparada à geometria com relação de lados das perfurações igual a 1,0, que conduziu aos piores resultados dentre todos os casos avaliados.

Buoyancy driven convection with a Cattaneo flux model
Authors: Straughan Brian , Tibullo Vincenzo , Passarella Francesca
Published: December 2023

We review models for convective motion which have a flux law of Cattaneo type. This includes thermal convection where the heat flux law is a Cattaneo one. We additionally analyse models where the convective motion is due to a density gradient caused by a concentration of solute. The usual Fick’s law in this case is replaced by a Cattaneo one involving the flux of solute and the concentration gradient. Other effects such as rotation, the presence of a magnetic field, Guyer–Krumhansl terms, or Kelvin–Voigt theories are briefly introduced.
Making Vessels for the Dead: Pottery-Making Practices, Chaîne Opératoire and the Use of Grog (Crushed Sherds) as a Technological and Cultural Choice during Late and Inca Periods in the Northwestern Argentine Region (Southern Andes)
Authors: De La Fuente Guillermo A. , Vera Sergio D.
Published: December 2023

Pottery-making practices have been approached by the use and application of the concept of chaîne opératoire in different parts of the world. This concept has allowed researchers to re-evaluate the social dimensions of technological studies as well as to explore aspects related to technical and social identity of ancient and modern artisans. In this article, we examine the use of grog (crushed sherds) to temper specific ceramic vessels (infant funerary urns) as material practice often used by ancient potters during Late (c. 950–1450 AD) and Inca (c. 1450–1532 AD) Periods in the Northwestern Argentine (NWA) region. The research shows that this practice can be understood as a ritual material practice with a long-standing tradition in the NWA region. Additionally, several alternative interpretations of this practice are explored in the light of different – animistic – understandings of how the Andean world works, and how people interact each other, with material things, and with landscape.

Development of a Video-Delivered Serial Drama Designed to Reduce Community Homophobia and HIV Stigma, Decrease Sexual Risk Behavior, and Increase HIV Testing Among Black Youth
Authors: O'Leary Ann , Willis Leigh A. , Henny Kirk D. , Madden Maurice , Koenig Linda J.
Published: December 2023

This article describes the development of a video serial drama intervention that was designed to address factors that influence HIV in the United States among Black youth. These include HIV testing, sexual behaviors not protected by condoms, negative attitudes towards sexual minorities, and HIV stigma. Behavior-change principles (social learning theory and education-entertainment) and input from members of the priority audience formed the basis of this 27-episode (3 minutes each) drama for dissemination on multiple platforms, including in public spaces or privately online. The developmental process, specifically involving members of the population of interest and use of behavioral theory, enriched the narrative elements and likely ensured intervention acceptability, enhancing effectiveness. Public health practitioners and prevention programmers may want to consider using this intervention and/or the narrative communication approach when intervening to change behavior.
“I Want to Be Really Clear”: What Male Sex Workers Want to Clarify With Prospective Clients Before Agreeing to Meet for Sex
Authors: Siegel Karolynn , Cabán María , Brown-Bradley Courtney J. , Schrimshaw Eric W.
Published: December 2023

Men who have sex with men (MSM) and engage in sex work (MSW) frequently meet clients through dating/hookup apps. This provides an opportunity to discuss the parameters of the exchange prior to meeting and to learn things about the prospective client and the risks he might pose. Limited research has examined the specific issues or topics MSWs discuss with clients before agreeing to meet. We analyzed interview data from a sample of 180 MSWs from eight U.S. cities who engaged in exchange sex with clients they had primarily met through dating/hookup apps and websites. Participants typically asked about clients' sexual interests and expectations regarding what will transpire when they meet to make sure they were compatible with their own boundaries and limitations. Most participants inquired about clients' sexual health and often discussed condom use. Assertiveness and communication skills training might help MSWs negotiate encounters with clients that promote health and safety.
La evolución dirigida: una valoración desde la propuesta filosófica de santo Tomás de Aquino

Los grandes avances en ingeniería genética, sobre todo el que se conoce como evolución dirigida “Directed evolution” y el “Gene drive” ofrecen al hombre la posibilidad de minimizar o erradicar enfermedades, mejorar ecosistemas, producir organismos mejorados de forma sencilla, asequible y eficaz. Sin embargo, la utilización de estas tecnologías, como en toda intervención en el orden teleológico de la realidad, representa riesgos físico-químicos y biológicos, pero, sobre todo, implicaciones éticas que es importante considerar. Este trabajo está encaminado a ofrecer algunos fundamentos filosóficos de valor perenne, que puedan ayudar a una valoración sobre el uso de las tecnologías utilizadas para una evolución dirigida, acudiendo a la síntesis filosófica de santo Tomás de Aquino.
San Isidoro de Sevilla. Las palabras y las cosas
Authors: Miró i Comas Abel
Published: December 2023

El objetivo de este artículo es desarticular dos prejuicios acerca de San Isidoro de Sevilla. El primero, que plana también sobre el conjunto de los pensadores medievales, lo situaría como un individuo absolutamente aislado de los problemas sociales de su tiempo, que desarrolla un sistema filosófico carente de toda raíz viviente. El segundo, sería el de apostillar sus Etymologiae como «mala filología», por el simple hecho de no adecuarse a los parámetros de la moderna ciencia filológica. Ambos prejuicios, como se va a argumentar, carecen de fundamento.
Domenico Fontana a Napoli 1592-1607: le opere per la committenza vicereale spagnola
Authors: Verde Paola Carla
Published: December 2023

Domenico Fontana nel 1592, dopo la morte di papa Sisto V, accetta l 'incarico del viceré di Napoli conte di Miranda per occuparsi della bonifica della campagna a nord di Napoli en el 1593 gli viene conferito l'ufficio di regio ingegnere. Il Fontana viene interpellato anche per la realizzazione del canale per convogliare le acque del fiume Sarno fino alla città di Torre Annunziata. Il successivo viceré conte d'Olivares gli affida la realizzazione di nuovi assi viari e larghi quali la via Olivares - dal molo grande al piccolo - la via Gusmana - dal baluardo dell'Alcala all'Arsenale - il largo di Castello e il largo delle Pigne nonché la realizzazione del nuovo porto (progetto mai portato a termine). Il Fontana realizzò anche due apparati effimeri: i catafalchi per le esequie di Filippo II ( 1599) e del viceré Lemos (1601). Proprio per il viceré Lemos realizza l' opera piu significativa della sua carriera di architetto maggiore del Regno: il nuovo Palazzo Reale. Il Fontana muore a Napoli il 28 giugno 1607, nella sua casa di via Nardones nei pressi del largo di Palazzo Reale, lasciando ai suoi eredi (alla moglie lsabella e ai figli Sebastiano, Giulio Cesare, Costanzo, Filippo, Olimpia, Felice e Flavia) un cospicuo patrimonio di beni mobili e immobili come si è desunto dal testamento olografo rinvenuto nell' Archivio di Stato di Napoli di cuisi riporta la trascrizione nell' appendice documentaria.
El retrato de Lady Anne Cliford
Authors: Suárez Huerta Ana María
Published: December 2023

En la Real Academia de Bellas Artes de San Fernando se conserva el retrato de una joven que durante años fue identificada como Bárbara de Braganza. El lienzo fue atribuido en un principio al pintor italiano Jacopo Amigoni y, posteriormente, al pintor francés Pierre Subleyras. Con el descubrimiento de un cargamento de obras de arte y antigüedades que viajaba en un barco inglés llamado Westmorland se ha logrado recomponer la historia de este retrato, el cual viajaba en el interior de un cajón marcado con las iniciales W.C. Gracias a este dato se logró averiguar que se trataba del retrato de Anne Clifford, condesa de Mahony, prima de un aristócrata británico llamado William Constable, quien encargó en 1778, a través del agente escocés James Byres, una copia de un retrato, de este mismo personaje, realizado anteriormente por Pierre Subleyras, a un pintor llamado Domenico Cherubini. Debido a que el barco fue capturado en el Mediterráneo, el paradero de dicha obra había sido hasta ahora desconocido. De hecho, su propietario, ante la imposibilidad de recuperarlo, encargó de nuevo otra copia, en esta ocasión, a Pompeo Girolamo Batoni, quien la realizó en 1785, tomando también como referencia el primer retrato de Pierre Subleyras. Por tanto, en la actualidad existen tres retratos similares. El original de Pierre Subleyras se encuentra en el Musée de Beaux Arts de Caén (Francia); la copia conservada en la Real Academia de Bellas Artes de San Fernando de Madrid, aquella que se pensaba desaparecida y que, sin embargo, se corresponde con la copia de Domenico Cherubini, y por último, la segunda copia de Pompeo Girolamo Batoni conservada en la residencia de William Constable, Burton Constable Hall (Inglaterra).
Irreverencia, reforma y revolución: escuelas de arte británicas en los 60
Authors: Rodríguez González Miguel Anxo
Published: December 2023

La década de los sesenta pasó a la historia por una serie de convulsiones estéticas, sociológicas y políticas de gran calado. Coincidiendo con el aumento general en el nivel de vida y el auge del consumo, surgieron actitudes radicales entre la juventud que se replantearon las prácticas artísticas vigentes, el modelo educativo y la relación de los ciudadanos con el poder político. Este artículo analiza los debates y transformaciones que tuvieron lugar en las escuelas de arte de Gran Bretaña, desde las primeras reformas oficiales de inicios de década, hasta las manifestaciones y rupturas radicales de 1968 y 1969, donde no sólo se ponía en cuestión el modelo estético imperante.
La Catedral de Cádiz de Vicente de Acero: la provocación de la arquitectura "crespa"
Authors: Marías Franco Fernando
Published: December 2023

La catedral de Cádiz, la última que se proyectó antes de la aparición de la Academia, ha sufrido en su estudio histórico los salvajes ataques que le dirigió esta institución desde finales del siglo XVIII. En este artículo se estudia este edificio en relación con las intenciones primeras de su arquitecto, Vicente de Acero y Acebo, conocidas a través de sus diseños y los panfletos que dirigió a la opinión pública en su defensa: una síntesis creativa de la tradición siloesca de las catedrales andaluces y las últimas novedades de la arquitectura italiana y francesa.

Nuevas aportaciones sobre el retablo de Santo Domingo de Tamarite de Litera: iconografía, origen, promoción y datación
Authors: Malé Miranda Gemma
Published: December 2023

El retablo de santo Domingo de Guzmán procedente de Tamarite de Litera es uno de los ciclos más antiguos dedicados a este santo y a la vez uno de los más complejos y desconocidos. Aproximadamente un siglo después que los dominicos permitieran la representación de sus santos miembros para impulsar su culto y a la vez su Orden se realizó este complejo ciclo dedicado a su fundador. La documentación recogida y una clave de bóveda conservada "in situ" me han permitido localizar la capilla dedicada a santo Domingo en la colegiata de Tamarite de Litera donde probablemente se encontraba este retablo hasta ser sustituido y trasladado a la sacristía de la iglesia de san Miguel de la misma población donde fue encontrado. Patrocinado por alguno de los miembros de la familia Entença, como indica uno de los escudos de su marco, fue realizado en el segundo tercio del siglo XIV según la comparación estilística con otras obras de su entorno y el graffiti realizado en la figura central. Contiene algunas escenas únicas en su género solo explicables por la intervención de un teólogo que conocía perfectamente la vida de este Santo y probablemente algún manuscrito italiano que le sirvió de modelo.
Miguel Perin en la escultura del Renacimiento español: la "Virgen con el Niño" 'de la catedral de León
Authors: García Nistal Joaquín
Published: December 2023

A principios del siglo XVI, la actividad de algunos artistas foráneos en la Península Ibérica fue determinante en el grado de madurez que la escultura renacentista fue alcanzando. La "Virgen con el Niño" (ca. 1525-1531) del Museo Catedralicio-Diocesano de León constituye un buen ejemplo de este fenómeno en el terreno de las imágenes elaboradas en barro cocido. EI presente artículo analiza el panorama artístico y cultural en que fue modelada la obra, prestando especial atención a aspectos tales como la importancia del patrocinio capitular leonés, el devenir histórico de la mencionada pieza o las atribuciones que se han ido barajando en la reciente historiografía y que se han centrado en las figuras de Pietro Torrigiano y Miguel Perin.
Alonso Cano en Madrid: nuevas aportaciones, nuevos problemas
Authors: Blanco Mozo Juan Luis
Published: December 2023

La llegada de Alonso Cano a Madrid supuso un cambio radical en su práctica profesional. Dejó atrás el gremio sevillano para trabajar en diferentes encargos de las Obras Reales de Felipe IV. En este contexto, trabajó y conoció a otros artistas como el platero Joaquín Pallares y el escultor Bernabé Contreras. El platero pudo ser el primer propietario del "Descenso al Limbo" de Alonso Cano. En este periodo realizó las pinturas de los retablos colaterales de la Magdalena de Getafe, sin participar en la fabricación de su obra de madera
El fuego de San Marcial y el fuego de San Antón en el contexto del arte medieval
Authors: Martín Ansón María Luisa
Published: December 2023

El presente estudio plantea una reflexión acerca de una epidemia desarrollada durante la edad media, el ergotismo, conocido con diferentes nombres, así como su reflejo en el arte medieval. La denominación de Fuego de San Marcial tuvo en España dos vías de penetración; a través del Camino de Santiago y gracias al establecimiento de la Orden de Grandmont en suelo hispano, propiciado por Teobaldo II de Navarra. Con este nombre se designa en varias de las Cantigas de Alfonso X el Sabio, que recogen acontecimientos acaecidos en santuarios franceses. Sólo en un caso, la acción se sitúa en territorio español pero se desconoce el origen de la leyenda que la inspira. En estos episodios, curiosamente, es a la Virgen a quien se acude y no a San Marcial, para implorar la curación. El nombre de Fuego de San Antón, al igual que en caso anterior, está vinculado a acontecimientos extraordinarios propiciados por las reliquias de los santos correspondientes. No obstante, su expansión y reflejo en el ámbito artístico parece haber sido más amplia. Sin duda, a ello contribuyó, de modo especial, la creación de la orden de los Antoninos y su capacidad hospitalaria.
Memoria del potere e gestione del territorio attraverso l'uso delle carte. La Sicilia in un atlante inedito di Gabriele Merelli del 1677
Authors: Manfrè Valeria
Published: December 2023

En este artículo se analizan dos atlas manuscritos de Gabriele Merelli, dedicados a Sicilia y desconocidos para la historiografía española. Del primero, hasta hoy inédito, dedicado al virrey Anielo de Guzmán, marqués de Castel Rodrigo, se ha reconstruido su génesis en relación con el contesto político-institucional de los acontecimientos bélicos de la revuelta de Messina (1674-1678); al mismo tiempo, se pone en relación con el segundo atlas de este mismo autor, fechado algunos meses después y que fue donado al virrey Juan José de Austria
Los primeros cien años de tira narrativa (1440-1550): Los inicios de la narración gráfica impresa
Authors: Bartual Moreno Roberto
Published: December 2023

Gracias al creciente interés académico por el cómic y la novela gráfica, algunos autores como Roger Sabin o Santiago García han llamado la atención sobre el parentesco que estos géneros modernos de narración gráfica comparten con las hojas volanderas que, durante la Baja Edad Media y el Renacimiento, referían vidas de santos, escenas populares, alegorías místicas o pasajes bíblicos mediante secuencias de viñetas. En su monumental obra The History of Comic Strip, David Kunzle reunió el primer y hasta el momento único corpus de este tipo de grabados, a los que denominó tiras narrativas, dejando pendiente la tarea de analizar sus características formales; tarea a la que nos proponemos dar comienzo en este artículo con el fin de establecer un puente de diálogo entre la narración gráfica y la historia del arte.

Herbal plants have been used, in light of their responsiveness and wide availability, for the construction of a pioneering nanomaterial. In this study, a colloidal suspension of gold nanoparticles (GNPs) was synthesized from an extract of Madhuca longifolia (ML) using chloroauric acid. For biomedical applications, Madhuca longifolia (ML) was used as a bioreductant as well as a capping agent The formed ML-GNPs were analyzed using different analytical techniques, antioxidant assays, and thiazolyl blue formazan assay against A549 cell lines to evaluate clinical relevance. They were further evaluated for their influence on antimicrobial activity using a disc diffusion test against two different microorganisms, Proteus vulgaris and Micrococcus luteus. The ML-GNPs produced had good antioxidant, antibacterial, and anticancer activities. The conformation of the XRD spectra with prominent characteristic planes was indexed to the face-centered cubic (fcc)-structured GNPs. Surface morphology analysis was used to determine the particle size of the GNPs. Fourier transform infrared spectra of the samples were used to determine the analogs for strong H bonding. The MIC values of biogenic GNPs against both strains of Proteus vulgaris and Micrococcus luteus was calculated as 0.29 and 0.96 g/mL, respectively, and triclosan was considered as 0.4 and 2 g/mL, respectively. The findings of this study will be beneficial for future studies of the therapeutic potential of ML-GNPs. Actively, ML-GNPs can be a capable material for formulating nanomedicines after subsequent clinical experiments.

Hyperglycemia contributes to a cascade of inflammatory responses in kidneys that result in the development of renal hypoxia and angiogenesis with subsequent chronic renal failure. As the hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) axis is a key pathway for neovascularization, the inhibition of this axis is a target for renal angiogenesis therapy. We speculate that Phenobarbital (PB) which has a potential to reduce vascularization in clinical settings might have an influence on the development of angiogenesis in diabetic kidney. The aim of the study was to explore the effects of PB on the HIF-1α and VEGF expression and angiogenesis in renal tissue of rats with hyperglycemia and diabetic nephropathy. Sixty-four male Wistar rats were devided into 4 groups: control group received a single intraperitoneal saline injection; PB group received 0.05% PB orally in drinking water; diabetic group received a single intra-peritoneal STZ (65 mg/kg) injection; PB-STZ group received 0.05% PB orally two weeks before STZ administration. At the end of the experiment period (8 weeks), the kidneys were removed and used for biochemical analyses. Serum glucose, urea and creatinine levels, IL-6 levels in kidney homogenate and changes in HIF-1α and VEGF gene expression were estimated. Hematoxylin-eosin staining was performed for histopathological exa­mination. The results obtained showed that both HIF-1α and VEGF gene expression and IL6 level in diabetic rat group were significantly elevated compared to that in control group, whereas in PB and PB-STZ groups, these indices were significantly down-regulated compared to the diabetic group. Abundant glomerular congestion and mesangial proliferation were detected in diabetic rat renal tissues. However, in PB-treated diabetic group, newly formed vessels were significantly decreased. These findings confirmed that phenobarbital, affecting the HIF-1α/VEGF signaling pathway, ameliorates angiogenesis after hyperglycemic kidney injury.
