Assessment of harvest and quality indexes in kiwifruit production at the South-East of Buenos Aires Province (Argentina)

Se realizó un seguimiento de la maduración de kiwis (Actinidia celiciosa (A. Chev.) Liang et Ferguson cv. Hayward) en una plantación comercial del sudeste de la provincia de Buenos Aires (Argentina), con la finalidad de definir índices de madurez y calidad y compararlos con los estándares vigentes en Nueva Zelanda y Chile. A intervalo semanal, desde las 13 semanas después de plena floración, se tomaron muestras de frutos para evaluar las siguientes variables: peso fresco, volumen, porcentaje de semillas negras, contenido de materia seca, acidez titulable y pH. De acuerdo con los mismos, el valor mínimo de sólidos solubles y el porcentaje de semillas negras exigido se alcanzaron durante la semana 21 después de plena floración y la firmeza de pulpa presentaba aún valores superiores al umbral recomendado. El momento óptimo de cosecha correspondió a plena temporada. Los resultados sugieren que la acidez titulable podría constituir otro índice de madurez. El porcentaje de materia seca no sería útil en fruta de plena temporada dado que los incrementos significativos se registran tempranamente. Sin embargo, puede ser útil como índice de calidad. Se plantea la posibilidad de utilizar la relación MS/AT como índice de calidad y de cosecha.Ripening of kiwifruit (Actinidia celiciosa (A. Chev.) Liang et Ferguson cv. Hayward) (Actinidia deliciosa cv. Hayward) was studied at an orchard located at the south-east of Buenos Aires province in Argentina with the aim of developing ripening and quality indexes and compare them to current standards used in New Zealand and Chile kiwifruit industries. Fruit samples were taken weekly, starting from 13 weeks after full bloom, in order to test the following variables: fresh weight, fruit volume, black seeds percentage, dry matter content, titratable acidity, and pH. Soluble solids content and black seeds percentage thresholds were attained during week 21 after full bloom. At this time, flesh firmness was still higher than the threshold value. Optimum harvest time took place during the season’s main harvest time. Results suggest that titratable acidity, which steadily increased during ripening, may be useful for indicating ripeness. Dry matter content may not be useful as a ripening index for main harvest fruit; because significant increases in this variable took place very early. However, dry matter content may still be useful as a quality index. The relationship between dry matter content and titratable acidity is proposed as a quality-harvest indexFil: Godoy, Carlos.

Studying Directionality in Simultaneous Interpreting through an Electronic Corpus: EPIC (European Parliament Interpreting Corpus)

Parallel corpora have long been awaited in simultaneous interpreting studies in order to validate existing theories and models. The present paper illustrates the development of the European Parliament Interpreting Corpus (EPIC), an open, parallel, multilingual (English, Italian and Spanish), POS-tagged corpus of European Parliament source speeches and simultaneously-interpreted target speeches. The aim of the project is to study recurrent lexical patterns and morphosyntactical structures across all the possible language combinations and directions, and verify empirically whether different strategies can be detected when interpreting from a Germanic language into a Romance one and vice-versa, or between two Romance languages. EPIC is freely available on-line for the research community to use and contribute to.Les corpus parallèles dans le domaine de la recherche sur l’interprétation simultanée étaient attendus depuis longtemps pour valider des théories et des modèles existants. La présente contribution a pour but de présenter EPIC (European Parliament Interpreting Corpus), un corpus ouvert, parallèle, multilingue (anglais, italien et espagnol) et avec étiquetage des parties du discours, composé de discours source prononcés au Parlement européen et de discours cible interprétés en simultanée. Le but de ce projet est d’examiner les modèles lexicaux et les structures morphosyntaxiques dans toutes les combinaisons linguistiques considérées et quelles que soient la langue de départ et d’arrivée, et de vérifier de manière empirique si des stratégies différentes peuvent être décelées lors d’une interprétation à partir d’une langue germanique vers une langue romane et viceversa, ou entre deux langues romanes. EPIC est librement accessible en ligne pour les chercheurs et est ouvert à leurs contributions

La práctica docente como escenario en la configuración de las subjetividades y de las prácticas del conocimiento

Este trabajo intenta aportar distintos modos de pensar y modos de hacer en el campo de la formación de las prácticas docentes que se juegan en el desarrollo curricular de la cátedra Práctica y Residencia en Instituciones Educativas, y su relación con la estructura curricular de la carrera a la que pertenece: el Profesorado en Ciencias de la Educación.El campo de las prácticas docentes es intersubjetivo, donde se reconoce la heterogeneidad y legitimidad de las diferencias entre los interlocutores. El practicante desde su estructura psicosocial interactúa en una red social que lo contiene y lo condiciona hasta cierto punto. Historias, formaciones y experiencias dependen del juego de intereses en función del cual toman posiciones unos en relación con otros.La cátedra, en este sentido, aspira a convertirse en un espacio transversal, de construcción de subjetividades y de integración y articulación entre teoría y práctica, para la creación de nuevos imaginarios y significaciones en las prácticas pedagógicas.La formación se constituye así, en un espacio para repensar el trayecto curricular y la práctica docente en particular. La perspectiva desde la que se plantea el trabajo se ubica en el terreno de la pedagogía de la formación desde una mirada compleja. En esta perspectiva, la formación profesional es un itinerario en el que los practicantes más que responder a lo que los profesores indican, es un recorrido que ellos deberán hacer por sí mismos:  construir teoría y hacer surgir el sentido de la práctica educativa

TEACHING PRACTICE AS A SETTING IN THE CONFIGURATION OF SUBJECTIVITIES AND KNOWLEDGE PRACTICES

This work tries to contribute different ways of thinking and ways of doing in the field of the formation of the teaching practices that are played in the curricular development of the Practice and Residence in Educational Institutions chair and its relationship with the curricular structure of the career to the which belongs: The Faculty of Educational Sciences. The field of teaching practices is intersubjective, where the heterogeneity and legitimacy of the differences between the interlocutors is recognized. The practitioner from his psychosocial structure interacts in a social network that contains and conditions him to a certain extent. Histories, formations and experiences depend on the set of interests based on which they take positions in relation to each other. The chair, in this sense, aspires to become a transversal space, for the construction of subjectivities and integration and articulation between theory and practice, for the creation of new imaginaries and meanings in pedagogical practices. Training thus constitutes a space to rethink the curricular path and teaching practice in particular. The perspective from which the work is proposed is located in the field of pedagogy of training from a complex perspective. In this perspective, professional training is an itinerary in which the practitioners, rather than respond to what the teachers indicate, is a journey that they must do by themselves: build theory and make the meaning of educational practice emerge

Enhanced surface interaction of water confined in hierarchical porous polymers induced by hydrogen bonding

Hierarchical porous polymer systems are increasingly applied to catalysis, bioengineering, or separation technology because of the versatility provided by the connection of mesopores with percolating macroporous structures. Nuclear magnetic resonance (NMR) is a suitable technique for the study of such systems as it can detect signals stemming from the confined liquid and translate this information into pore size, molecular mobility, and liquid−surface interactions. We focus on the properties of water confined in macroporous polymers of ethylene glycol dimethacrylate and 2-hydroxyethyl methacrylate [poly- (EGDMA-co-HEMA)] with different amounts of cross-linkers, in which a substantial variation of hydroxyl groups is achieved. As soft polymer scaffolds may swell upon saturation with determined liquids, the use of NMR is particularly important as it measures the system in its operational state. This study combines different NMR techniques to obtain information on surface interactions of water with hydrophilic polymer chains. A transition from a surface-induced relaxation in which relaxivity depends on the pore size to a regime where the organic pore surface strongly restricts water diffusion is observed. Surface affinities are defined through the molecular residence times near the network surface.Fil: Silletta, Emilia Victoria. Consejo Nacional de Investigaciones Científicas y Técnicas.

Spatially Resolved Monitoring of Drying of Hierarchical Porous Organic Networks

Evaporation kinetics of water confined in hierarchal polymeric porous media is studied by low field nuclear magnetic resonance (NMR). Systems synthesized with various degrees of cross-linker density render networks with similar pore sizes but different response when soaked with water. Polymeric networks with low percentage of cross-linker can undergo swelling, which affects the porosity as well as the drying kinetics. The drying process is monitored macroscopically by single-sided NMR, with spatial resolution of 100 μm, while microscopic information is obtained by measurements of spin?spin relaxation times (T2). Transition from a funicular to a pendular regime, where hydraulic connectivity is lost and the capillary flow cannot compensate for the surface evaporation, can be observed from inspection of the water content in different sample layers. Relaxation measurements indicate that even when the larger pore structures are depleted of water, capillary flow occurs through smaller voids.Fil: Velasco, Manuel Isaac.

The molecular chaperone Hsp90 is a component of the cap-binding complex and interacts with the translational repressor Cup during Drosophila oogenesis

In metazoa, the spatio-temporal translation of diverse mRNAs is essential to guarantee proper oocyte maturation and early embryogenesis. The eukaryotic translation initiation factor 4E (eIF4E), which binds the 5′ cap structure of eukaryotic mRNAs, associates with either stimulatory or inhibitory factors to modulate protein synthesis. In order to identify novel factors that might act at the translational level during Drosophila oogenesis, we have undertaken a functional proteomic approach and isolated the product of the Hsp83 gene, the evolutionarily conserved chaperone Hsp90, as a specific component of the cap-binding complex. Here we report that Hsp90 interacts in vitro with the translational repressor Cup. In addition, we show that Hsp83 and cup interact genetically, since lowering Hsp90 activity enhances the oogenesis alterations linked to diverse cup mutant alleles. Hsp90 and Cup co-localize in the cytoplasm of the developing germ-line cells within the germarium, thus suggesting a common function from the earliest stages of oogenesis. Taken together, our data start elucidating the role of Hsp90 during Drosophila female germ-line development and strengthen the idea that Cup has multiple essential functions during egg chamber development

From a life story to a story of formation

Así, la tarea efectuada se limitó a la revisión e indagación respecto de referencias al uso de la historia de vida en las ciencias sociales, en el campo de la historia, la antropología y la sociología; para luego investigar su aplicación en los campos más específicos de formación de los docentes y, posteriormente, de la formación de adultos en general. En ese recorrido nos encontramos con distintas miradas y posiciones. Por ello y a los fines de esta comunicación presentaremos una selección, es decir, un recorte de aquellos antecedentes que nos han servido para mostrar el camino realizado. El uso de las historias de vida en la docencia e investigación universitaria puede ser recuperado como una herramienta para la historización y reconocimiento de los procesos de formación de adultos y su ubicación en un campo especifico de estudio e interpretación. De esta manera, las historias de vida devienen en historias de formación que, al especificarse, facilitan la comprensión que el sujeto hace de sus propios procesos de formación, como así también la identificación en profundidad del campo de la formación para avanzar en su comprensión y en el descubrimiento e indagación de sus significados. This piece of work tries to show, from a historical perspective, the studies and investigations from where they have been done in different fields and from different approaches, in the subjects that referred to the life story and its later extension to the fields of formation as “Formation story”. Therefore, the task done was limited to the revision and search about referncies to the use of the story of life in the social sciences, in the field of history, the antrophology and the sociology; to then investigate its aplication in more spécific fields of educational and, later, the formation of adults in general. In this course we find ourselves with differents point of views and positions. Because of that and in order to communicate this we present a selection, it is to say, a profile of those antecedents which help us to show the way done. The use of life stories in the teaching and university investigations is able to be recover as a tool used for history and recognition of proccess of adults formation and their placed in the studies speceific fields and interpretation. From this point, the life stories become in formation stories that, specifically, it facilitate the understanging of the human being of his own proccess of formation,as well as the deep identification of the field of his formation to advance in his comprehension and the discovery and search of its meanings

A Comparative Evaluation of Deep Learning Techniques for Photovoltaic Panel Detection From Aerial Images

Solar energy production has significantly increased in recent years in the European Union (EU), accounting for 12% of the total in 2022. The growth in solar energy production can be attributed to the increasing adoption of solar photovoltaic (PV) panels, which have become cost-effective and efficient means of energy production, supported by government policies and incentives. The maturity of solar technologies has also led to a decrease in the cost of solar energy, making it more competitive with other energy sources. As a result, there is a growing need for efficient methods for detecting and mapping the locations of PV panels. Automated detection can in fact save time and resources compared to manual inspection. Moreover, the resulting information can also be used by governments, environmental agencies and other companies to track the adoption of renewable sources or to optimize energy distribution across the grid. However, building effective models to support the automated detection and mapping of solar photovoltaic (PV) panels presents several challenges, including the availability of high-resolution aerial imagery and high-quality, manually-verified labels and annotations. In this study, we address these challenges by first constructing a dataset of PV panels using very-high-resolution (VHR) aerial imagery, specifically focusing on the region of Piedmont in Italy. The dataset comprises 105 large-scale images, providing more than 9,000 accurate and detailed manual annotations, including additional attributes such as the PV panel category. We first conduct a comprehensive evaluation benchmark on the newly constructed dataset, adopting various well-established deep-learning techniques. Specifically, we experiment with instance and semantic segmentation approaches, such as Rotated Faster RCNN and Unet, comparing strengths and weaknesses on the task at hand. Second, we apply ad-hoc modifications to address the specific issues of this task, such as the wide range of scales of the installations and the sparsity of the annotations, considerably improving upon the baseline results. Last, we introduce a robust and efficient post-processing polygonization algorithm that is tailored to PV panels. This algorithm converts the rough raster predictions into cleaner and more precise polygons for practical use. Our benchmark evaluation shows that both semantic and instance segmentation techniques can be effective for detecting and mapping PV panels. Instance segmentation techniques are well-suited for estimating the localization of panels, while semantic solutions excel at surface delineation. We also demonstrate the effectiveness of our ad-hoc solutions and post-processing algorithm, which can provide an improvement up to +10% on the final scores, and can accurately convert coarse raster predictions into usable polygons
