Teología y vida , 2002, DOI: 10.4067/S0049-34492002000200005
Abstract: the article presents the first part of a study on origens' interpretation of chapter 6 of the gospel by saint john. the study attempts to gather and examine the various texts related to the exegesis about jn 6, comprised in the works by origen which we have come to us. then, there is an attempt to outline the foundations of origen's interpretation to jn 6. given that the material is abundant, this first part presents and examines only the texts related to the narrative part (jn 6, 1-21) and starts introducing the texts related to jesus' words (jn 6, 35-59). in fact, it clear that origen's interest focuses particularly on jesus' speech in which he calls himself "bread of life". this paper presents the texts comprised in de oratione, comment on john, and comment on mathew. the second part of this study presents the remaining texts related to the "bread of life" speech, which are contained in the homilies on the genesis, homilies on exodus; homilies on leviticus, homilies on numbers and homilies on joshua. the author also makes a balance of the presence of this issue in the other works by origen which have to come to our days, to end up emphasising the train of thought of origen's exegesis about jn 6
Juan 6 en la interpretación de Orígenes (Ia Parte)
Antonio Castellano
Teología y vida , 2002,
Abstract: El artículo contiene la primera parte de un estudio sobre la interpretación de Orígenes al capítulo 6 del Evangelio de Juan. Este estudio se propone primero reunir y examinar los distintos textos, relacionados a la exégesis de Jn 6, contenidos en las obras de Orígenes que nos han llegado. En un segundo momento se buscará trazar las líneas de fondo de la interpretación origeniana a Jn 6. Siendo el material abundante, en esta primera parte se presentan y examinan los textos relacionados a la parte narrativa (Jn 6,1-21), y se inician a presentar los textos relacionados al discurso de Jesús (Jn 6,35-59). En efecto, está claro que el interés de Orígenes se ha dirigido particularmente al discurso en el que Jesús se declara "pan de la vida". Aquí se verán los textos contenidos en el De Oratione, en el Comentario a Juan, y en el Comentario a Mateo. En la segunda parte del estudio se terminará de presentar los textos relacionados al tema del "pan de la vida" y que están contenidos en las Homilías al Génesis, Homilías al éxodo, Homilías al Levítico, Homilías a los Números y Homilías a Josué. Haré también una revisión y balance de la presencia de esta temática en el resto de las obras origenianas que nos han llegado. En fin, intentaré poner de relieve las líneas de fondo de la exégesis de Orígenes a Juan 6 The article presents the first part of a study on Origens' interpretation of chapter 6 of the gospel by Saint John.

Analysis of the possession ball in soccer: frequency, duration and transition Análisis de las posesiones de balón en fútbol: frecuencia, duración y transición
J. Castellano
Motricidad : European Journal of Human Movement , 2010,
Abstract: El análisis de la complejidad del rendimiento en fútbol es a día de hoy una asignatura todavía pendiente. La fluctuación de los comportamientos que se dan durante el juego es una realidad difícil de explicar y predecir. Entre las variables posibles, parece ser que la posesión del balón puede ser uno de los indicadores de rendimiento que puede llevar a un equipo a imponerse en el juego ofensivo, aunque no siempre en el marcador. El objetivo del presente estudio es describir la alternancia entre las posesiones de balón de uno y otro equipo, que permita inferir sobre los desequilibrios que estos cambios pueden generar en la organización del equipo. Para ello se ha tomado una muestra de 11 partidos de la Eurocopa’08, estimada a partir de la Teoría de la Generalizabilidad (TG). Se han codificado las posesiones del balón de uno y otro equipo que se sucedía dentro de cada BJ, completándolo con las interrupciones reglamentarias marcadas por el árbitro. Los resultados muestran un incremento significativo en el número de balones en juego de una única posesión, al tiempo que los que incluían la secuenciación de dos o más posesiones se han visto disminuidas. Palabras Clave: Fútbol, rendimiento, análisis notacional, posesión de balón, generalizabilidad. The analysis of the complexity of soccer is still a pending subjet. The fluctuation of the behaviors that occur during the game is a difficult reality to explain and to predict. Between the possible variables, it seems to be that, the ball possession can be one of the performance indicators that can take a team to impose in the offensive game, although it is not always at score. The objective of the present study is to describe the ball possessions of both teams, to know the changes that they can generate in the organization of the team. Eleven matches of the last Euro’08 were observed, registered and analyzed, considered from the Generalizability Theory (GT). The ball possessions of both teams have been codified in each ball in game, completing it with the set pieces marked by the referee. The results show a significant grow in the number of balls in game of only one possession, in consequence that include that two or more ball possessions have been diminished. Key Words: Soccer, performance, notational analysis, ball possession, generalizability
LOADS INTERACTION DOMAINS METHODOLOGY FOR THE DESIGN OF STEEL GREENHOUSE STRUCTURES
Sergio Castellano
Journal of Agricultural Engineering , 2007, DOI: 10.4081/jae.2007.1.21
Abstract: Aim of this research is to develop a design methodology which correlates main structural design parameters, whose production is characterised by high levels of standardization, such as the height of gutter or the distance between frames, with actions on the greenhouse. The methodology, based on the use of charts and abacus, permits a clear and a direct interpretation of the structural response to design load combinations and allows the design of structural improvements with the aim of the optimization of the ratio benefits (structural strength)/costs. The study of structural interaction domains allowed a clear and a direct interpretation of the structural response to design load combinations. The diagrams highlight not only if the structure fulfils the standard requirements but also the safety levels with respect to design load combinations and allow the structural designer how to operate in order to optimize the structural response with standard requirements achieving the best ratio benefits (structural safety)/ costs. The methodology was developed basing on criteria assigned by EN13031 on two different kinds of greenhouse structures: an arched greenhouse with a film plastic covering and a duo pitched roof greenhouse cover with rigid plastic membranes. Structural interaction domains for arched greenhouse showed a better capability of the structure to resist to vertical loads then to horizontal one. Moreover, the climatic load distribution on the structure assigned by EN13031 is such that the combination of climatic actions is less dangerous for the structure then their individual application. Whilst, duo pitched roof steel greenhouse interaction domains, showed a better capability of the structure to resist to vertical loads then to horizontal one and that, in any case, the serviceability limit states analysis is more strict then the ULS one. The shape of structural domains highlighted that the combination of actions is more dangerous for the structure then the application of single loads. Charts and abacus very easy to interpret and can be used also by non technicians in order to arrange a quick and reliable estimate of the costs of the structure. For instance, it is sufficient to know characteristic values of snow loads and wind speed to evaluate what is the distance of frame of the arched greenhouse to fulfil EN13031 requirements.

Effect of network topology on the ordering dynamics of voter models
Claudio Castellano
Physics , 2005, DOI: 10.1063/1.2008600
Abstract: We introduce and study the reverse voter model, a dynamics for spin variables similar to the well-known voter dynamics. The difference is in the way neighbors influence each other: once a node is selected and one among its neighbors chosen, the neighbor is made equal to the selected node, while in the usual voter dynamics the update goes in the opposite direction. The reverse voter dynamics is studied analytically, showing that on networks with degree distribution decaying as k^{-nu}, the time to reach consensus is linear in the system size N for all nu>2. The consensus time for link-update voter dynamics is computed as well. We verify the results numerically on a class of uncorrelated scale-free graphs.
A global root-finding method for high dimensional problems
Fabrizio Castellano
Mathematics , 2009,
Abstract: A method to solve the problem f(x) = 0 efficiently on any n-dimensional domain Omega under very broad hypoteses is proposed. The position of the root of f, assumed unique, is found by computing the center of mass of an Omega-shaped object having a singular mass density. It is shown that although the mass of the object is infinite, the position of its center of mass can be computed exactly and corresponds to the solution of the problem. The exact analytical result is implemented numerically by means of an adaptive Monte Carlo sampling technique which provides an exponential rate of convergence. The method can be extended to functions with multiple roots, providing an efficient automated root finding algorithm.
Smoothness of Kuranishi atlases on Gromov-Witten moduli spaces
Robert Castellano
Mathematics , 2015,
Abstract: Kuranishi atlases were introduced by McDuff and Wehrheim to build a virtual fundamental class on moduli spaces of J-holomorphic curves and resolve some of the challenges in this field. This paper considers Gromov-Witten moduli spaces and shows they admit a smooth enough Kuranishi atlas to be able to define a Gromov-Witten virtual fundamental class in any virtual dimension. The key step for this result is the proof of a stronger gluing theorem.
Stallings' decomposition theorem for totally disconnected locally compact groups
Ilaria Castellano
Mathematics , 2015,
Abstract: An analogue of Stallings' decomposition theorem is proved for totally disconnected locally compact groups, i.e., a totally disconnected locally compact group $G$ with more than one end splits either as an HNN-extension $H\ast_K^t$ or non-trivially as a free product with amalgamation $H\ast_K J$, where $K$ is compact and open. This splitting theorem can be formulated in terms of rational discrete cohomology of $G$ with coefficients in the standard bimodule $\mathrm{Bi}(G)$ (cf. Theorem A). Using an accessibility result due to Y. Cornulier, an analogue of the Karrass-Pietrowski-Solitar theorem is proved for t.d.l.c. groups, i.e., a compactly presented totally disconnected locally compact group $G$ of rational discrete cohomological dimension at most 1 is isomorphic to the fundamental group $\pi_1(\mathcal{G},\Lambda)$ of a finite graph of profinite groups $(\mathcal{G},\Lambda)$ (cf. Theorem B).
Detection of Group B Streptococcus in Brazilian pregnant women and antimicrobial susceptibility patterns

Brazilian Journal of Microbiology , 2010, DOI: 10.1590/S1517-83822010000400024
Abstract: group b streptococcus (gbs) is still not routinely screened during pregnancy in brazil, being prophylaxis and empirical treatment based on identification of risk groups. this study aimed to investigate gbs prevalence in brazilian pregnant women by culture or polymerase chain reaction (pcr) associated to the enrichment culture, and to determine the antimicrobial susceptibility patterns of isolated bacteria, so as to support public health policies and empirical prophylaxis. after an epidemiological survey, vaginal and anorectal specimens were collected from 221 consenting laboring women. each sample was submitted to enrichment culture and sheep blood agar was used to isolate suggestive gbs. alternatively, specific pcr was performed from enrichment cultures. antimicrobial susceptibility patterns were determined for isolated bacteria by agar diffusion method. no risk groups were identified. considering the culture-based methodology, gbs was detected in 9.5% of the donors. twenty five bacterial strains were isolated and identified. through the culture-pcr methodology, gbs was detected in 32.6% specimens. bacterial resistance was not detected against ampicillin, cephazolin, vancomycin and ciprofloxacin, whereas 22.7% were resistant to erythromycin and 50% were resistant to clindamycin. gbs detection may be improved by the association of pcr and enrichment culture. considering that colony selection in agar plates may be laboring and technician-dependent, it may not reflect the real prevalence of streptococci. as in brazil prevention strategies to reduce the gbs associated diseases have not been adopted, prospective studies are needed to anchor public health policies especially considering the regional gbs antimicrobial susceptibility patterns.
