CORSIKA Implementation of Heavy Quark Production and Propagation in Extensive Air Showers
Bueno, A.;Gascon, A.
High Energy Physics - Phenomenology , 2013,
Abstract: Heavy quarks are commonly produced in current accelerator experiments. Hence it is natural to think that they should be likewise created in collisions with larger center of mass energies like the ones involving ultra-high energy cosmic rays and atmospheric nuclei. Despite this fact, a detailed treatment of heavy hadrons is missing in Monte Carlo generators of Extensive Air Showers (EAS). It is a must to improve the description of how heavy flavours appear and evolve in atmospheric showers. With this goal in mind, we study two different models for heavy quark production in proton-air collisions. We also analyze a dedicated treatment of heavy hadrons interactions with atmospheric nuclei. This paper shows how those models have been implemented as new options available in CORSIKA, one of the most used EAS simulators. This new computational tool allows us to analyze the effects that the propagation of heavy hadrons has in the EAS development

Nuevas iniciativas en torno a la formación e investigación en traducción biosanitaria
Antonio Bueno García
Panace@ : Revista de Medicina, Lenguaje y Traducción , 2007,
Abstract: La Dirección General de Traducción de la Comisión Europea ha enviado a los Estados miembros unas recomendaciones con vistas a elaborar un máster europeo de traducción que permita potenciar la formación de especialistas, entre los que figuran los traductores biosanitarios. La Universidad de Valladolid ha sido la primera en dar forma a este compromiso con la creación de un programa oficial de posgrado, el Máster de Traducción Profesional e Institucional (Máster TPI), de un a o de duración (60 créditos ECTS), que forma a los licenciados y diplomados de distintas especialidades en las destrezas profesionales y en el conocimiento de la traducción en la Unión Europea. En el programa, de cinco módulos de especialidad, colaboran hasta cinco escuelas o facultades distintas y once áreas departamentales. El apoyo del Grupo de Investigación Interdisciplinar Intersemiótica, Traducción y Nuevas Tecnologías (GIR ITNT) resulta fundamental en el desarrollo de los sistemas telemáticos y en la investigación aplicada. ----------------------------------------- New initiatives on biomedical translation training and research. The European Commission's Directorate-General for Translation sent all Member States of the EU a set of instructions recommending the elaboration of a European master on translation promoting highly-skilled specialists in different fields, biomedical ones included. The University of Valladolid was the first one to give form to this commitment by means of an Official Postgraduate Programme, the so-called Máster de Traducción Profesional e Institucional (Máster TPI), which lasts one academic year (60 ECTS), and which prepares undergraduate students from different backgrounds in the professional skills and expertise in translation required for the European Union. This programme, consisting of five modules of specialization, benefits from the collaboration of five university schools and eleven department areas of study. The support of the interdisciplinary research group, sponsored by the University of Valladolid: "Intersemiotics, Translation and New Technologies" (ITNT) has proved to be essential for the development of telematic systems and applied research.
La utilidad de la flora americana en el proyecto expedicionario de la Espa a Ilustrada
González Bueno, A.
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 1995,
Abstract: The new model, economical and political, devised by the enlightened Spanish was going to propiciate the execution of an ambitious, utopical and, in certain manner, original, plan of reconnaissance and exploitation of the colonial American facilities with evident tints monopolists. The development of this idea demanded the knowledge and the inventory of the natural resources as previous stage to the process of commercialization. The institutional development of this project is today very well-known; Being over from the commencements of the XlXth Century, the heavy bureaucratic machine still more sluggish because of the entrance of the French troops to Spain, it will allow that the final outcome were delayed until 1831. El nuevo modelo político-económico ideado por los ilustrados espa oles propiciaría la ejecución de un ambicioso, utópico y, en cierto modo, original plan de reconocimiento y explotación de los recursos coloniales americanos con claros tintes monopolistas. El desarrollo de esta idea exigía el conocimiento y el inventario de los recursos naturales como etapa previa al proceso de comercialización. El desarrollo institucional de este proyecto es hoy bien conocido; finiquitado desde los comienzos del siglo XIX, la pesada máquina burocrática, ralentizada aún más con la entrada de las tropas francesas en Espa a, permitirá que el desenlace final se retrase hasta 1831.

A comparative study on two characteristic parametrizations for high energy pp and pp total cross sections
A. Bueno,J. Velasco
Physics , 1996, DOI: 10.1016/0370-2693(96)00454-6
Abstract: Available high energy data for both pp and \=pp total cross sections ($ 5 \ GeV \ < \ \sqrt s \ < \ 1.8 \ TeV$) are described by means of two well-known distinct parametrizations, characteristic of theoretical (``Regge-like" expression) and experimental (``Froissart-Martin-like" expression) practices, respectively. Both are compared from the statistical point of view. For the whole set of present data, statistical analysis ($\chi^2/d.o.f.$) seems to favour a ``Froissart-like" ((ln $s$)$^{\gamma \approx 2}$ ) rise of the total cross section rather than a ``Regge-like" ($s^{\epsilon}$) one.
Compara??o entre tecnologias de climatiza??o para cria??o de frangos quanto a energia, ambiência e produtividade
Bueno, Leda;Rossi, Luiz A.;
Revista Brasileira de Engenharia Agrícola e Ambiental , 2006, DOI: 10.1590/S1415-43662006000200035
Abstract: with the objective to compare two technological options of climatization for the production of broilers, in the city of rio claro-s?o paulo state, an experiment was carried out in two commercial sheds of a farm, being one with system of ventilation and nebulization and 13 birds m-2 (g1) and the other with system of ventilation composed of tunnel of exhaust fans and pump of nebulization and with 18 birds m-2 (g2). the period of the experiment was 14 months with complete analysis of five lots of creation in different seasons of the year, where the variable related to energy efficiency, thermal comfort and productive indices were analyzed. it was observed that the two sheds presented similar values of thermal comfort and animal productivity. in relation to the consumption of electrical energy, g2 presented higher values than g1, however with chicken production 38% more than g1. the indices of energy efficiency had been low, demonstrating the possibilities for adoption of measures for conservation and rationalization of electrical energy.
Ecos del deseo en el cuerpo, el enigma de la autoinmunidad // Desire echoes in the body autoinmunity enigma
Juliana María Bueno Restrepo
Affectio Societatis , 2012,
Abstract: El presente artículo es el resultado de la investigación Afección autoinmune y goce, llevada a cabo en el marco de la Maestría en Investigación psicoanalítica de la Universidad de Antioquia (Colombia). El propósito del mismo es desarrollar uno de los hallazgos de la investigación, según el cual habría una posible articulación entre los enigmas que plantean las afecciones autoinmunes y los avatares del deseo, los cuales tendrían un eco en el cuerpo. Lo anterior, partiendo de la concepción psicoanalítica del cuerpo como territorio de lo psíquico, como lugar de inscripción de las huellas que se producen en la relación al Otro, en la que se juega lo concerniente al goce y al deseo. // This article is the result of Autoimmune Condition and Jouissance research, carried out as part of the Master in Psychoanalytic Research of the University of Antioquia, Colombia. The purpose is to develop one of the research findings, acnigmas posed by autoimmune conditions and the vicissitudes of desire which would have an echo in the body. This is based on the psychoanalytic idea of the body as a psychic territory, place of the inscription of the traces that occur in the relation to the Other, involving jouissance and desire.
Afecciones autoinmunes: de fenómeno a síntoma
Bueno Restrepo Juliana María
Desde el Jardín de Freud , 2012,
Abstract: El presente artículo plantea la hipótesis de que la afección autoinmune podría devenir síntoma, lo cual abre una nueva perspectiva clínica. Se hace un recorrido por la concepción del síntoma conversivo en Freud y por la consideración del síntoma como acontecimiento del cuerpo en Lacan; igualmente, se presentan las lógicas que podría tener la afección autoinmune en algunas personas: como manifestación fenoménica puramente orgánica que no los concierne como sujetos; como fenómeno que se vuelve síntoma gracias a la introducción de un dispositivo de palabra, y como síntoma constituido antes de las entrevistas de la investigación. Maladies auto-immunes: de phénomène à sympt me Une hypothèse est posée : la maladie auto-immune pourrait bien muter en sympt me; ceci ouvre des nouveaux points de vue cliniques. Un parcours est fait par l’idée du sympt me conversif chez Freud et par la notion de sympt me comme événement du corps, chez Lacan. Des éventuelles logiques de la maladie auto-immune sont présentées comme manifestation phénomènique purement organique où certains ne se sentent pas concernés en tant que sujets ; comme phénomène qui devient sympt me grace à l’introduction d’un dispositif de parole ; et comme sympt me constituée avant les entretiens préliminaires de l’étude. Autoimmune conditions: from phenomenon to symptom This article proposes the hypothesis that autoimmune conditions could be understood as symptoms, which opens up a new clinical perspective on this matter. This work investigates the idea of conversive symptoms in Freud and Lacan’s notion that a symptom is an event of the body. It also presents the logics that could result in an autoimmune condition in some people: either as a purely organic phenomenal manifestation that does not concern them as subjects; as a phenomenon that becomes a symptom thanks to the introduction of a word device; or as a symptom constituted before interviews conducted during this investigation.

Nutrición Hospitalaria , 2008,
Abstract: Objectives: To analyse the effect of zinc supplementation in growth and nutritional status of a homogeneous group of newborns with intra uterine growth retardation and asymmetric growth. The effect of changes of zinc status on growth and leptin serum concentrations was also analysed. Population and methods: A double blind, randomised clinical trial was designed in order to detect differences in growth between zinc and placebo groups during the first 6 months of life. 31 infants were included either to the zinc group (n = 14) (38.8 ± 1.4 weeks GA, 2,171 ± 253 g body weight) or the placebo group (n = 17) (38.9 ± 1.1 weeks GA, 2,249 ± 220 g body weight). The zinc group received a supplement of 3 mg elemental zinc per day (as zinc sulphate). Results: There were not significant differences between groups for anthropometric measurements through the study period. We found a significant effect of the study group, in hair zinc concentrations, but not in serum zinc concentrations; post-hoc comparisons for hair zinc revealed that there were significant differences between groups at 1, 2, and 6 months of age. Changes in serum and hair zinc concentrations from baseline to 6 months, showed significant correlations with changes in weight/age and length/age z-scores, in the supplement group. Changes in leptin serum concentrations during follow-up, showed significant correlations with changes in sum of 4 skinfolds and weight/age z-score, in the placebo group. Changes in hair zinc concentration through the study period showed significant correlations with changes in leptin serum concentrations from baseline to 6 months of follow-up. Conclusions: In a homogeneous group of intra uterine growth retardation infants with asymmetric growth, 3 mg/day zinc supplementation do not show significant improvements in weight and length growth. Changes in zinc status were related with changes in weight and length during the first 6 months of life. Changes in leptin serum concentrations were related with changes in the anthropometric indices of body fat accretion. Objetivos: Valorar el efecto de la suplementación con cinc en el crecimiento y estado nutricional de un grupo homogéneo de recién nacidos con retraso de crecimiento intra-uterino asimétrico. También se analizó el efecto de los cambios en el status del cinc en el crecimiento y las concentraciones séricas de leptina. Población y método: Se dise ó un ensayo clínico randomizado y doble ciego, con el fin de detectar diferencias en el crecimiento entre los grupos recibiendo cinc o placebo, durante los seis primeros meses de vida. 31 n
