Exploring rabbit semen cryopreservation and the crucial role of cryobank: unveiling advantages and promising perspectives
Full text linkOver the years, efforts have been made to establish a reference protocol for the first Italian rabbit semen bank. Here, we will provide an overview of our group’s key discoveries, which have led us to identify an effective freezing protocol for rabbit semen. However, a drawback of our protocol involves diluting the semen with the freezing media at fixed dilution ratios, resulting in significant variability in the sperm number per straw. Addressing this limitation underscores the need to standardise the freezing protocol by investigating the effect of sperm concentrations within straws on the reproductive performances of cryopreserved rabbit semen. In this regard, in an in vivo trial, 192 multiparous receptive rabbit does were randomly assigned to six treatment groups, including a control group. The remaining groups were inseminated with doses containing 15, 25, 35, 55 and 75×106 sperm, respectively. Sperm concentrations of 25, 35 and 55×106/straw exhibited higher reproductive performances compared to other tested concentrations and were akin to fresh semen. Through the adoption of freezing protocols with standardised sperm concentrations, cryobanks can safely preserve rabbit population genetic resources, offering invaluable support for future breeding and research efforts
Una animación transgresora para un mensaje alternativo: en torno al animalismo de Las vidas de Marona
Full text linkThis article investigates the representation of the animal and the human-animal relationship in Marona’s Fantastic Tale (Anca Damian, 2019). After considering the traces of the animal turn in the audiovisual in general and within the realm of animation in particular, we proceed to the study of the motion picture guided by the methodology of film analysis and attending to animation’s unique aesthetics. We first connect the type of protagonism that the film grants to the dog with the weak anthropomorphization to which the character is subjected. Next, we evaluate the resources that contribute to put us in the dog's shoes, highlighting the sensorialization and somatization of the discourse. Next, we examine the portrayal of the human characters and emphasize the intersubjective propensity of the protagonist. Finally, the conclusions highlight the synergies between the experimental formal proposal and the animalistic message of the film.El presente artículo investiga la representación del animal y de la relación humano-animal en Las vidas de Marona (Anca Damian, 2019). Tras considerar las huellas del giro animal en el audiovisual en general y en el ámbito de la animación en particular, procedemos al estudio del largometraje guiados por la metodología del análisis fílmico y atendiendo a las especificidades estéticas de la animación. Conectamos en primera instancia el tipo de protagonismo que la película concede a la perra con la débil antropomorfización a la que el personaje es sometido. A continuación, valoramos los recursos que contribuyen a ponernos en la piel de la perra, destacando la sensorialización y somatización del discurso. Seguidamente, examinamos el retrato de los personajes humanos e incidimos en la propensión intersubjetiva de la protagonista. Por último, las conclusiones remarcan las sinergias entre la experimental propuesta formal y el mensaje animalista del film
Convergencias narrativas entre videojuegos y animación: análisis del anime Log Horizon y cómo los MMORPG nutren el subgénero isekai
Full text linkIn the last decade, Japanese commercial animation has been marked by the rise and success of isekai. An anime sub-genre whose main characteristic is to transport its protagonists to alternative worlds. The creation of these other worlds is clearly inspired by fantasy MMORPG videogames since these universes operate on similar logics to those of videogames. However, if the isekai is nourished by MMORPGs, are these productions capable of explaining to us what these videogames are? This article examines how the anime Log Horizon (Touno, 2013) describes to the viewer what fantasy MMORPGs are, how they operate and what are the characteristics of MMORPGs. Furthermore, it allows us to observe how MMORPG videogames are integrated as a resource in anime inventiveness and their components are transformed into narrative and visual resources. To this purpose, we analyse the narrative-visual content of the 25 episodes that make up the first season of Log Horizon (Ishihara, 2013-2014).En la última década, la animación comercial japonesa se ha visto marcada por el ascenso y éxito del isekai. Un subgénero anime cuya característica principal es transportar a sus protagonistas a mundos alternativos. Para construir esos otros mundos se percibe una clara inspiración en los videojuegos MMORPG de fantasía, puesto que dichos universos operan en lógicas similares a las del videojuego. Ahora bien, si el isekai se nutre de los MMORPG, ¿explican sus producciones en qué consisten estos videojuegos? El presente artículo examina cómo el anime Log Horizon (Touno, 2013) describe al espectador qué son, cómo operan y cuáles son las características de los MMORPG de fantasía. Además, permite observar cómo los videojuegos MMORPG se integran como recurso en la inventiva anime y sus componentes se transforman en recursos narrativos y visuales. Para ello, se analiza el contenido narrativo-visual de los 25 episodios que componen la primera temporada de Log Horizon (Ishihara, 2013-2014)
Strong chain transitivity in hyperspaces of uniform spaces
Full text linkWe apply topological definitions of strong chain transitivity and characterizetopological strong chain transitivity for the induced maps on hyperspaces ofuniform spaces. We prove that, if the induced maps on such hyperspaces exhibittopological strong chain transitivity then the base map satisfies the propertyof topological strong chain transitivity
Dynamical behavior of a general non-autonomous dynamical system
Full text linkIn this work, we investigate dynamical notions such as minimality, almost periodicity, equicontinuity, transitivity, proximality and periodicity for a general non-autonomous dynamical system. We provide necessary and sufficient conditions for a non-autonomous system to be minimal. We prove that for an equicontinuous system (X,F), if x is almost periodic then OH(x) is uniformly almost periodic. We also establish preservance of almost periodicity under uniform convergence. We also establish some results capturing the qualitative behavior of a general non-autonomous dynamical system
C1(X) on the edge of C2(X)
Full text linkGiven a continuum X and a positive integer n, let Cn(X) be the hyperspace consisting of all nonempty closed subsets of X having at most n components. For a subcontinuum A of X having empty interior, consider the following properties: A is a subcontinuum of colocal connectedness, X\A is continuumwise connected, A is a nonblock subcontinuum, A is a shore subcontinuum, A is not a strong centre. In this paper, we prove that C1(X) has all of these properties in Cn(X) if n ≥ 3, and we study when C1(X) has one of these properties in C2(X)
Pre-symmetric c-distances and characterization of complete cone metric spaces
Full text linkThe main goal of this research is to express the definition of pre-symmetric c-distances in cone metric spaces inspired by pre-symmetric w-distances defined by Romaguera and Tirado [Mathematics. 12 (2024), 2:305] and give the properties of this type of c-distances along with some examples. Then we introduce Suzuki's theorem regarding a pre-symmetric c-distance and obtainrelationship between several important contractions with respect to cone metric spaces. Finally, we will state a characterization of the completeness of cone metrics using fixed point theorems, which is different from previous descriptions of complete cone metric spaces
β-Normality in locales
Full text linkIn this paper, we establish the theory of β-normal locales which are the point- free counterparts of β-normal spaces which were introduced by Arkhangel’skii and Ludwig. We give characterizations of β-normal locales using some types of open sublocales. Certain circumstances are exhibited in which normality coincides with β-normality. For instance, we use the localic Kateˇtov-Tong insertion theorem to prove that every β-normal locale which is also a coframe is normal. This result argues that there does not exist a finite β-normal locale which is not normal. Included here is also an answer to Murtinova ́’s question about the existence of a regular β-normal space which is not Tychonoff. The study of β-normal locales leads to some variants of β-normal locales, namely α-normal locales and almost weakly β-normal locales. This paper also examines preservation and reflection of β-normal locales by localic maps
Net art died but is doing well: anotaciones
Full text linkThe production of art conceived for the Internet experienced a period of decline in the 2010s. However, with the need for social isolation due to the COVID-19 pandemic starting in 2020, artists turned their attention to the Internet as a medium of creation, transcending the diffusion of other types of art works. Production is strengthened, with a substantial number of creations conceived during the critical period of the Pandemic. But, as life goes back to normal, is Internet art production destined for a new downfall? In light of this, artists Fabio FON and Soraya Braz launched a call for artists entitled Net art died but is doing well, with the purpose of understanding the current status of that production. An online exhibition is held in the context of the sixth edition of The Wrong Biennale, one of the largest digital art events in the world, which started in November 2023.La producción de arte concebida para Internet vivió un período de declive durante la década de 2010. Sin embargo, con la necesidad de aislamiento social debido a la pandemia de COVID-19 a partir de 2020, la atención de los artistas se centró nuevamente en Internet como un medio de creación, yendo más allá de la simple difusión de obras creadas en otros lenguajes. La producción resurge, con numerosas creaciones durante el período crítico de la pandemia. Pero, a medida que la vida vuelve a la normalidad, ¿estarán las obras para Internet destinadas a un nuevo declive? Para reflexionar sobre esto, los artistas Fabio FON y Soraya Braz lanzaron una convocatoria abierta para artistas titulada Net art died but is doing well con el propósito de entender el estado actual de esta producción. Una exposición en línea se lleva a cabo en el contexto de la sexta edición de The Wrong Biennale, uno de los mayores eventos de arte digital del mundo, a partir de noviembre de 2023
A Systematic Literature Review Protocol to understand the Healthcare Service Innovation Ecosystem
Full text linkThe research's primary goal is to address the innovation ecosystem in healthcare services to understand how interaction among stakeholders occurs and how that interaction influences or does not influence the results obtained from the innovation process. We aim to build a theoretical model applicable to the healthcare sector context regarding the questions we aim to answer through systematic review: Does the relationship between stakeholders of the Health Services Innovation Ecosystem affect innovation outcomes? The target population includes the actors within the ecosystem (partners, stakeholders, and other participants); the phenomenon of interest is how these actors interact, with the context being the innovation process, specifically focusing on the outcomes of their interactions. This article defines the framework proposal for systematic review. A methodological approach was developed considering the parameters of the PRISMA 2020 Statement since the definition of the review objective was to collect and analyze data. As a result, the research question has been validated, and studies included in the review have been identified. The results will be analyzed and generated in the following research phase
