    The effect of biostimulants on fruit quality of processing tomato grown under deficit irrigation

    Water shortage can be a restrictive factor for the growth and quality of vegetable crops. Considering the alleviating effects of biostimulant application against water stress, this study aimed to investigate the effect of four biostimulant products (protein and amino acids with carboxylic acids (Tr1); protein and amino acids with seaweed extracts (Tr2); humic and fulvic acids with seaweed extracts (Tr3); SiO2 (Tr4); and control (no biostimulants added)) and two irrigation systems (regulated deficit irrigation (RDI)—65% of field capacity and regular irrigation (RI)—100% of field capacity) on quality parameters of processing tomato fruit. Regulated deficit irrigation and biostimulant application increased the energetic value, carbohydrates, and free sugars content, while organic acids showed a variable response to biostimulant use. In terms of tocopherols (α-, β-, γ-, δ-) and carotenoids (lycopene and β-carotene), regular irrigation and biostimulant application negatively affected their content, while Tr3 treatment had a beneficial impact on these lipophilic compounds under RDI conditions. The main fatty acids were palmitic (C16:0) and linoleic (C18:2n6) acids, which increased when plants were treated with Tr3 and Tr1 biostimulants under a deficit regime. Antioxidant activity (assessed by TBARS and OxHLIA assays) and total phenolic and flavonoids content also showed a variable response to the studied factors. In particular, the application of Tr3 and the control treatment under RDI increased the total phenolic content, while the control and Tr3 treatments under the same irrigation regime recorded the highest antioxidant activity. In conclusion, our results indicate that the adoption of eco-friendly strategies such as regulated deficit irrigation and biostimulant application can beneficially affect the quality traits of processing tomatoes.This research has been co-financed by the European Regional Development Fund of the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH—CREATE—INNOVATE (project code: T2EDK-05281).info:eu-repo/semantics/publishedVersio

    Authenticating the writings of Julius Caesar

    In this paper, we shed new light on the authenticity of the Corpus Caesarianum, a group of five commentaries describing the campaigns of Julius Caesar (100–44 BC), the founder of the Roman empire. While Caesar himself has authored at least part of these commentaries, the authorship of the rest of the texts remains a puzzle that has persisted for nineteen centuries. In particular, the role of Caesar’s general Aulus Hirtius, who has claimed a role in shaping the corpus, has remained in contention. Determining the authorship of documents is an increasingly important authentication problem in information and computer science, with valuable applications, ranging from the domain of art history to counter-terrorism research. We describe two state-of-the-art authorship verification systems and benchmark them on 6 present-day evaluation corpora, as well as a Latin benchmark dataset. Regarding Caesar’s writings, our analyses allow us to establish that Hirtius’s claims to part of the corpus must be considered legitimate. We thus demonstrate how computational methods constitute a valuable methodological complement to traditional, expert-based approaches to document authentication

    Cuentos de nunca acabar. Aproximaciones desde la interculturalidad

    Cuentos de nunca acabar. Aproximaciones desde la interculturalidad, surge después de la pandemia y su imposibilidad de socializar “en persona” con los compañeros de eventuales encuentros, porque la Comprensión Lectora tenía que reinventarse para su nueva reflexión cognitiva, adaptación contextual y reconstrucción del conocimiento. Este renovado enfoque de la realidad postpandemia, concebido en el marco de la educación intercultural comunitaria, busca potencializar los entornos naturales, sociales y culturales como recursos de aprendizaje multidisciplinario a través del lenguaje animado de los cuentos. En este marco, había que dinamizar la asignatura de Comunicación Oral y Escrita, que se dicta en los Primeros Niveles de los Centros de Apoyo de Otavalo, Cayambe, Latacunga y Riobamba, mediante un eje transversal donde los estudiantes escriban fundamentados en valores de la cosmovisión andina, considerando que provienen de varios lugares de la sierra y amazonía ecuatoriana. Todo surgió del encuentro presencial de un sábado cualquiera donde los estudiantes realizaban ejercicios narrativos, logrando una apreciable respuesta de imaginación, más emotiva que la clásica tarea de las Unidades, tanto así que, pasados unos días, seguían llegando sus escritos a mi correo. Entonces nos pusimos manos a la obra, cada estudiante tendría dos opciones como Actividad Integradora, la primera consistía en escribir un cuento de su propia inspiración, y la segunda analizar un clásico para comentar sus valores y antivalores. La mayor parte de estudiantes decidió escribir su propio cuento, de donde se escogieron algunas participaciones que podrían considerarse originales, para una edición que, respetando la transcripción de la tradición oral que prima en los sectores comunitarios, nos concretamos en revisar la puntuación y ortografía para publicarlos. Con esto buscamos innovar la Actividad Integradora, por algo más práctico y operativo para configurar los Objetos de Aprendizaje que buscamos. Así nació, en medio del camino, este libro de Cuentos de nunca acabar. Aproximaciones desde la interculturalidad, que ponemos en sus manos. Hernán Hermosa Mantilla Quito, junio de 202
