Una Estrategia para la enseñanza de metodologías ágiles

El propósito de este trabajo es presentar una estrategia docente para la enseñanza de metodologías ágiles, que hemos refinado durante más de 10 años de aplicación en asignaturas de Ingeniería Informática, y que actualmente acabamos de trasladar al Grado en Ingeniería Informática. Se trata de 2 asignaturas consecutivas que integran tanto el aprendizaje de métodos y técnicas para el desarrollo de software como su puesta en acción en el marco de un proyecto de desarrollo de software. Si bien se ofrece una visión global de las metodologías, gran parte del contenido de estas asignaturas se centra en el enfoque ágil. En la asignatura Proceso del Software (PSW) se introducen los conceptos de Kanban [1], Lean Software Development [6], Scrum [3,7] y Extreme Programming [2], y se complementa su aprendizaje con el apoyo de diversos ejemplos y actividades. También en esta asignatura se realiza un trabajo práctico de exploración y planificación de un proyecto ágil. En la asignatura Proyecto de Ingeniería de Software (PIN) se forman equipos de 8 a 10 integrantes y se recrea el desarrollo ágil de un producto software empleando diversas prácticas ágiles, siguiendo un proceso iterativo e incremental, realizando 3 sprints, y todo ello apoyado con una herramienta para la gestión del proyecto. La organización y todo el material de PSW está disponible en psw.tuneupprocess.com.SUMMARY -- strategy that we have refined over 10 years of application in computer engineering courses, and now we have just moved to the new Degree in Computer Engineering. These two consecutive subjects integrate both, the learning of software development methods and practices and its implementation in the context of a project. We provide an overview of methods and practices, but certainly most of the contents of these subjects are focused on agile methods. The subject Software Process introduces the concepts and practices included in the most popular agile methods; Kanban, Lean Software Development, Scrum and Extreme Programming, and their learning is complemented with a practical activities. In this subject the students also work on the exploring and planning phase of an agile project. In the subject Software Engineering Project working in teams participate in the agile development of a software product using a set agile practices and using a tool for collaboration support, following an iterative and incremental process, and carrying on three sprints. All the educational materials of PSW subject are available for download from psw.tuneupprocess.com

Fungicides and the grapevine wood mycobiome: a case study on Tracheomycotic Ascomycete Phaemoniella chlamydospora reveals potential for two novel control strategies

Original ResearchPhaeomoniella chlamydospora is a tracheomycotic fungus that colonizes the xylem of grapevines (Vitis vinifera L.), causing wood discoloration, brown wood streaking, gummosis, and wood necrosis, which negatively affect the overall health, productivity, and life span of vines. Current control strategies to prevent or cope with P. chlamydospora infections are frequently ineffective. Moreover, it is unclear how fungicides commonly applied in vineyards against downy and powdery mildew agents affect the wood mycobiome, including wood pathogens such as P. chlamydospora. In this study, we used next-generation sequencing to assess the effects of foliar spray of grapevines with inorganic (copper oxychloride and sulfur), synthetic (penconazole and fosetyl-aluminum), and natural (Blad) fungicides currently used against the downy and powdery mildews. The subjects of our investigation were (i) the resident wood mycobiome, (ii) the early colonization by a consortium of fungal wood endophytes (ACEA1), (iii) the wood colonization success of P. chlamydospora, and (iv) the in planta interaction between P. chlamydospora and ACEA1, under greenhouse conditions, in rooted grapevine cuttings of cv. Cabernet Sauvignon. The data obtained suggest that the resident mycobiome is affected by different fungicide treatments. In addition, the early colonization success of the endophytes composing ACEA1 varied in response to fungicides, with relative abundances of some taxa being overrepresented or underrepresented when compared with the control. The wood colonization by P. chlamydospora comported significant changes in the mycobiome composition, and in addition, it was greatly affected by the foliar spray with Blad, which decreased the relative abundance of this pathogen 12-fold (4.9%) when compared with the control (60.7%) and other treatments. The presence of the pathogen also decreased considerably when co-inoculated into the plant with ACEA1, reaching relative abundances between 13.9% and 2.0%, depending on the fungicide treatment applied. This study shows that fungicides sprayed to prevent infections of powdery and downy mildews have an control strategies to fight P. chlamydospora, namely, the foliar spray with Blad and the use of ACEA1. Further studies to confirm these results are requiredinfo:eu-repo/semantics/publishedVersio

Characterization of Cadophora luteo-olivacea and C. melinii isolates obtained from grapevines and environmental samples from grapevine nurseries in Spain

[EN] Fifty-eight Cadophora luteo-olivacea and three C. melinii isolates were recovered from grapevines showing black vascular streaking and decline symptoms characteristic of Petri disease, and from different stages of the grapevine nursery process in Spain. The isolates were studied by means of phenotypical characterization, DNA analysis and pathogenicity tests. The morphological characters studied included conidiophore, phialide and conidial morphology. Colony characters and pigment production on MEA, PDA and OA were also examined. Phenotypical data were subjected to cluster analysis, which clearly separated C. luteo-olivacea isolates into four groups. Mating tests were performed on all possible combinations for each Cadophora species but no sexual fruiting bodies were produced. Partial sequences of the nuclear ribosomal internal transcribed spacer (ITS), beta-tubulin (BT) and the elongation factor 1¿ (EF) were analysed, but no genetic variation occurred within the C. luteo-olivacea isolates or within the C. melinii isolates in any of the regions studied. Pathogenicity tests were conducted on 1-year-old grapevine cuttings of four different rootstocks using four C. luteo-olivacea isolates and one isolate of C. melinii. All Cadophora isolates except the C. melinii isolate caused significantly longer lesions in the xylem of grapevine rootstocks than in the controls.This research was financially supported by the Projects AGL2006-11884-C04-01 (Ministerio de Educación y Ciencia, Spain), RTA2007-00023-C04-03 and RTA2010-00009-C03-03 (Programa Nacional de Recursos y Tecnologías Agrarias, Ministerio de Educación y Ciencia, Spain), and the European Regional Development Fund (ERDF).

Field evaluation of grapevines rootstocks inoculated with fungi associated with Petri disease and esca

[EN] One year old grapevine rootstock cuttings of 41B Millardet Grasset 140 Ruggeri 161 49 Couderc 1103 Paulsen and 110 Richter were inoculated with pathogens associated with Petri disease and esca of grapevine to determine the effects of fungal infection on percentage of cuttings emerging from dormancy shoot weight and disease severity The cuttings were vacuum inoculated with spore suspensions of either Cadophora luteo olivacea five species of Phaeoacremonium or Phaeomoniella chlamydospora and planted in two field sites in March 2008 Most of the fungal pathogens caused a significant reduction in the percentage of cuttings emerging from dormancy and shoot weight and a significant increase in disease severity in all grapevine rootstocks except 161 49 Couderc Rootstocks 110 Richter and 140 Ruggeri were greatly affected by fungi associated with Petri disease and esca In general Pa chlamydospora and Pm parasiticum caused the greatest reduction in percentage of cuttings emerging from dormancy and shoot weight and the highest increase in disease severity Regression analyses showed a significant correlation between percentage of cuttings emerging from dormancy and disease severity and between shoot weight and disease severity in almost all rootstocks inoculated with Pa chlamydosporaThis research was financially supported by project RTA2007 00023 C04 03 (Programa Nacional de Recursos y Tecnologias Agrarias Ministerio de Educacion y Ciencia Spain)Gramaje, D.; García-Jiménez, J.; Armengol Fortí, J.

El cuajado del fruto en el aguacate (Persea americana) y su relación con el aporte de carbohidratos. Efecto de la aplicación de triazoles

[ES] En el aguacate, existe una gran competencia nutricional entre el desarrollo vegetativo y reproductivo, que determina el porcentaje de cuajado. De hecho, la floración y la primera brotación y crecimiento de los brotes depende marcadamente de los azúcares solubles y de reserva acumulados. Con el fin de disminuir esta competencia en favor del desarrollo reproductivo, en muchos países productores se realizan aplicaciones foliares de diferetes triazoles, compuestos inhibidores de la biosíntesis de giberelinas, en el momento de la floración e inicio del cuajado. Aunque se ha observado que estos tratamientos mejoran el porcentaje de cuajado y reducen el problema de la alternancia, no se conoce su mecanismo. Con el fin de conocer el mecanismo a través del cual estas sustancias regulan el cuajado de esta especie, se realizaron aplicaciones foliares de paclobutrazol y edranol a diferente concentración en el momento de la floración del cv. Hass. Se evaluó el efecto que estas sustancias tienen sobre la viabilidad del grano de polen y sobre el contenido endógeno en carbohidratos de consumo y de transporte.[EN] In avocado gibberellic acid (AG) applied at a concentration of 25 mg/l at the onset of flowering immediately increased vegetative growth, whereas paclobutrazol (PBZ), an inhibitor of the gibberellin biosynthesis, at the same concentration, reduced it later in time. However the percentage of flower set did not change. Hence, our results do not allow conclude that fruit set depends mainly on the competition for carbohydrates between vegetative and reproductive growth in avocado. PBZ significantly advanced flower abscission, although the number of fruits finally set was the same for AG treated trees or not treated control trees. It suggests that in avocado fruit set is not mostly under a competition phenomenon among developing organs. Flowers treated with PBZ immediately reduced translocating and reducing concentration with regard to control, mainly perseitol and glucose concentration, respectively, in accordance with its abscising effect. However, perseitol concentration remained lower in treated flowers whereas that of glucose increased, in accordance with the advanced abscission due to PBZ. The possibility that the reduction of pollen viability was related with lower fruit set of PBZ treated flower was also studied, results showing that triazoles have not any effect on the process, and suggesting that their effect reducing fruit set in avocado is not related with ovule fertilization.López Gramaje, M.

Agronomic behavior of grape rootstocks resistant to young vine decline in Santa Catarina State, Brazil

Young vine decline, caused by the ground pearl or margarodes (Eurhizococcus brasiliensis) and pathogenic fungi (Cylindrocarpon, Phaeoacremonium and others), is a major problem in many vineyards of Southern Brazil. According to previous studies, the most resistant roostocks were hybrids of tropical species, such as Vitis caribaea (IAC 572, IAC 571-6, IAC 766) and V. cinerea (IAC 313). A medium resistance level was observed in V. champinii (Dog Ridge) and Muscadinia rotundifolia hybrids (VR 043-43). However, these rootstocks have not being used in grape growing areas of Southern Brazil. An experiment was carried out to evaluate the agronomic characteristics of the scion cultivar Moscato Embrapa grafted on these rootstocks compared to Paulsen 1103 and R99, considered standards for this region. The tropical rootstocks IAC 313, IAC571-6, and IAC 766 induced earlier bud break compared to Paulsen 1103, the opposite of VR043-43 and Dog Ridge. In general aspects, all rootstocks tested can be used for grape production. Even the tropical rootstocks with no winter dormancy behave as normal rootstocks when grafted. IAC 572 has an advantage of not inducing early bud break. However, excessive vigor is the most limiting factor for IAC 572, requiring especial management practices to control vegetative development

Treball Final de Grau en Enginyeria en Disseny Industrial i Desenvolupament de Productes. Codi: DI1048. Curs: 2014/2015Este proyecto tiene como principal objetivo demostrar que se tienen las aptitudes y conocimientos necesarios para elaborar un proyecto de diseño y desarrollo de producto. La realización marca el fin de la etapa de estudio de la carrera de Grado en ingeniería en diseño industrial y desarrollo de producto, en la Universidad Jaume I de Castellón. De este modo, se da paso a los documentos elaborados que reflejan las competencias adquiridas tanto a nivel formal y estético como a nivel técnico. Con la evolución que está teniendo la tecnología, y su influencia en nuestras vidas, es cuestión de tiempo que cada uno de los objetos que nos rodea se vea adaptado a este progreso. Mesas táctiles, muebles con adaptadores para nuestros dispositivos o casas inteligentes, en las que todo su interior puede ser controlado desde nuestro smartphone, son cosas que vemos cada día con más frecuencia. Pero, aunque muchas conexiones entre los diferentes dispositivos suelen efectuarse por sistemas inalámbricos como wifi o bluetooth, la eliminación del cableado queda aún algo lejos, teniendo que estar conectados a una fuente de alimentación mediante cableados, lo que limita bastante nuestros movimientos. Por este motivo, uno de los muebles en los que más tiempo pasamos, tiene que evolucionar y adaptarse a los progresos, el escitorio. El fin de este proyecto es la presentación de un nuevo concepto de mesa de trabajo donde, además de proporcionarnos la utilidad que tiene una mesa común, nos permitirá una gestión de la superficie de trabajo para poder trabajar con total libertad, sin la molestia del cableado de lámparas, altavoces o regletas
