Comportamiento de cuatro cultivares de Cucurbita maxima cv. zapallito frente al parasitismo del nematodo de las agallas Meloidogyne incognita
No full textEl nematodo de las agallas, Meloidogyne incognita, es causante de pérdidas productivas en los principales cultivos hortícolas que se realizan en el albardón costero santafesino. El objetivo de la investigación fue determinar la reacción de cuatro cultivares comerciales de zapallito redondo de tronco (Cucurbita maxima cv. zapallito) frente al parasitismo de M. incognita. Las experiencias se condujeron en macetas bajo invernadero y se evaluaron los cultivares Nacional, Premier, Sais superselección y Máximo. Los tratamientos consistieron en inocular plantas de cada cultivar con 100 juveniles de segundo estadio de M. incognita y de sus correspondientes testigos no inoculados. A los 45 días de la inoculación se determinó el número de agallas, Índice de Agallas, número de masas de huevos, Índice de Masas de Huevos, número de huevos y el factor e reproducción. Los cuatro cultivares estudiados demostraron ser susceptibles a M. incognita.The root-knot nematode, Meloidogyne incognita, causes yield losses in many horticultural crops in the coastal área of Santa Fe province. The aim of this research was to determine the reaction of four commercial cultivars of summer squash (Cucurbita maxima cv. zapallito) when parasitized by M. incognita. The experiments were conducted in pots under greenhouse conditions and Nacional, Premier, Sais superselection and Máximo cultivars were evaluated. The treatments consisted of plants of each cultivar inoculated with 100 second-stage juveniles of M. incognita and its corresponding control. 45 days after inoculation the number of galls, Gall Index, number of egg masses, Eggs Mass Index, number of eggs and reproduction factor were determined. The four cultivars studied showed susceptibility to M. incognitaFil: Guzmán, Alejandro. Universidad Nacional del Litoral. Facultad de Ciencias Agrarias; ArgentinaFil: del Valle, Eleodoro Eduardo.

Marcelo dascal and the literal meaning debates
No full textWhat role does literal meaning play in people’s understanding of indirect and figurative language? Scholars from many disciplines have debated this issue forseveral decades. This chapter describes these debates, especially focusing on the arguments between the author and Marcelo Dascal. I suggest that Dascal’s defense of “moderate literalism” may have some validity, contrary to some of my earlier arguments against this point of view. The chapter acknowledges the strong contribution that Marcelo Dascal has made to interdisciplinary discussions on language and thought
Marcelo Cohen’s Work : Between Fantastic Sociology and Fictional Geography
No full textCette thèse étudie les notions de géographie imaginaire et de sociologie fantastique dans l’œuvre de Marcelo Cohen (Buenos Aires, 1951). Le corpus de travail comprend l’ensemble de la production de fiction narrative de l’auteur (contes, nouvelles et romans en une vingtaine d’ouvrages) entre son premier recueil de récits, Lo que queda (1972), et son roman Balada (2011). La thèse est organisée en trois parties : la première (« Marcelo Cohen et son œuvre. Perspectives théoriques et méthodologiques ») propose une présentation de l’auteur et de son œuvre et un bilan théorique et pratique des notions de géographie imaginaire et de sociologie fantastique ; la deuxième (« Écrire l’espace ») analyse la construction de l’espace dans le corpus choisi dans une double démarche chronologique et figurative ; la troisième (« Littérature et société ») se penche sur les manifestations des dimensions idéologiques, sociales et politiques, et sur les relations entre l’individu et la société dans les ouvrages de Marcelo Cohen. Le travail s’achève par une réflexion globale sur la poétique et l’esthétique de l’auteur argentin.This thesis considers such concepts as fictional Geography and fantastic Sociology in Marcelo Cohen’s work (Buenos Aires, 1951).The body of this research includes all the narrative fiction by this author (some twenty tales, short stories and novels in total), between his first collection of stories, Lo que queda (1972), and his novel Balada (2011).Our thesis develops three domains : the first one (« Marcelo Cohen and his work, a theoretical and methodological outlook ») introduces the author and his work, along with a theoretical and practical evaluation of such concepts as fictional Geography and fantastic Sociology ; the second one (« Space in writing ») analyzes the make of space in the selected books, in a dual approach : both chronological and representational ; the last one (« Literature and society ») addresses the expressions of ideological, sociological and political dimensions, plus the relationship between a particular person and his/her society in Marcelo Cohen’s works. This research ends with a global consideration of poetry and estheticism in the work of our Argentinean author

Fusarium Species Causing Dry Rot of Carrot in Central Argentina
No full textCarrot (Daucus carota L. subsp. sativus) cultivation is important in Argentina, with the Garay department in Santa Fe provincebeing a key production area. In recent years, dry rot symptoms have afflicted various carrot cultivars, resulting in substantialfield losses and postharvest discards. Several soilborne pathogens, including Fusarium species, have been implicated in similarcarrot diseases globally. This study aimed to identify the specific causal agent responsible for dry rot in carrots in centralArgentina to enable targeted disease management strategies. Samples of symptomatic carrots were collected from fields in theGaray department. Fungal isolates were obtained from the infected tissue and subjected to morphological and molecular analyses.Pathogenicity tests were conducted to confirm the ability of the isolates to cause disease symptoms in carrots. Based on morphologicaland molecular identification, isolates were identified as Fusarium nirenbergiae, Fusarium triseptatum and Fusariumsolani. Pathogenicity tests demonstrated that the three Fusarium species were capable of causing dry rot symptoms in carrots.This study represents the first report of Fusarium nirenbergiae, Fusarium triseptatum and Fusarium solani causing dry rot incarrots in Argentina.Fil: Favaro, María Alejandra.

Marcelo Cohen. Las fundaciones de la ciencia ficción
No full textThe present work analyzes the forms that Science fiction takes in Marcelo Cohen´s narrative. By outlining certain characteristics of the genre, it is considered the ways how these are reformulated according to the Romantic epistemological paradigm that the author picks up, blending it with concepts of quantum and chaos theories, to postulate a model of Realism. Within this context, the initial analysis of the author´s self-fashioning and essays is useful to think the proposal of a singular ontology in his fictions
Marcelo Cohen. Las fundaciones de la ciencia ficción
No full textEl presente trabajo analiza la forma que asume la ciencia ficción en la obra de Marcelo Cohen. A partir de un recorrido por ciertas particularidades del género se reflexiona acerca de cómo éstas se reformulan de acuerdo con el paradigma epistemológico romántico que el autor retoma, y que conjuga con conceptos de la cuántica y de las teorías del caos, en vistas de la postulación de un modelo de realismo. En este contexto, el análisis inicial de las autofiguraciones del autor y de sus ensayos sirve para pensar la propuesta de una ontología singular en sus ficciones.The present work analyzes the forms that Science fiction takes in Marcelo Cohen´s narrative.

Between kludges and displacements: signed Marcelo Mirisola
No full textO ensaio pretende acompanhar a construção da assinatura de Marcelo Mirisola, comentando alguns aspectos de seu repertório ficcional apostando na hipótese de que o cinismo que se cola à construção da identidade autoral é um impasse à transformação de sua assinatura, de seu nome de autor. A partir de Joana a contragosto o autor tenta um turning point através da metaficcionalização de sua própria condição como escritor no cenário literário contemporâneo expondo as aporias de inscrição de uma marca de autoria. Tal como disse Ricardo Lísias no comentário que fez à Joana, a Contragosto, é possível capturar um movimento de deslocamento da voz autoral na direção de uma dicção mais melancólica e que põe a descoberto as estratégias de ficcionalização da própria figura autoral nas narrativas, as imagens de escritor tematizadas na ficção. Nesse sentido, então, o presente ensaio pretende tentar capturar elementos recorrentes nas narrativas, laboriosamente reiterados que apontam para a consolidação de uma obra e por outro lado, quando metaficcionalizados, indicam a exaustão e a aporia de uma voz narrativa já confirmada.This essay aims to trace the construction of the «signature» of Marcelo Mirisola, commenting on some aspects of his fictional repertoire and focusing on the hypothesis that the cynicism attached to the process of construction of this authorial identity is an obstacle to the transformation of his «signature», his name as an author. From Joana a Contragosto onward, the author has been attempting a turning point by metafictionalizing his own condition as a writer in the contemporary literary scene, exposing the paradoxes of the inscription of a mark of authorship. In this sense, then, this essay aims to capture recurring elements in the author’s narratives that, on the one hand, by way of their laborious repetition, indicate the consolidation of a work and, on the other hand, when metafictionalized, indicate both the exhaustion and the aporia of a narrative voice already confirmed

No full textEsta pesquisa tem por objeto de estudo o fazer musical aplicado no contexto da educação empresarial. Foi investigado em que medida este processo constitui um caminho de conhecimento de si e conhecimento do outro, bem como procurou-se compreender seu potencial, paradoxos e peculiaridades, tanto para a educação empresarial quanto para a psicologia social. Nesta pesquisa, foi trilhado um caminho essencialmente fenomenológico, no qual optou-se, primeiramente, por apresentar e descrever o contexto de trabalho e, em seguida, descrever a experiência vivida em uma série de oficinas musicais, realizadas com trabalhadores de três empresas. Os dados da pesquisa foram colhidos sob forma de entrevistas, diários de campo dos participantes e gravações em vídeo das oficinas. Uma vez compilados, os registros relevantes foram organizados em categorias, a fim de permitir uma análise dos significados emergentes no processo. Os resultados encontrados foram, então, discutidos sob o aporte teórico e reflexões acerca: da musicalidade, da arte como caminho de conhecimento, do trabalho educativo no meio empresarial, e das questões da percepção da música, de si mesmo e do outro. Por fim, indaga-se sobre o potencial papel do fazer musical tanto no âmbito do desenvolvimento do indivíduo quanto na dinâmica das interações sociais e de trabalho no mundo empresarial contemporâneoMusic-making applied in a business educational context is the object of this research. We investigated to what extent this process constitutes a path to the knowledge of oneself and to the knowledge of the other. We tried as well to understand its potentials, paradoxes and peculiarities for a business education process. This study was based on a essentially phenomenological approach. First it is presented and described the work context followed by the description of the lived experience made in a series of musical workshops, with workers of three companies. The survey data was collected through interviews, field diaries of the participants and video recordings of the workshops. Once compiled, the relevant records have been organized into categories to allow an analysis of the emergent meanings in the process. The results are then discussed under theoretical support and ideas about musicality, art as a way of knowledge, educational work in the business environment and questions of music perception and perception of oneself and of the other. Finally we ask questions about the potential role of music-making both in the individual development as well as in the social dynamics and work interactions in a contemporary business worl
