Non-ionizing radiation and spectrum occupancy measurement
No full textThe expansion in the use of wireless telecommunication systems and its associated rain of non-ionizing electromagnetic radiation motivates the study of these emissions and the impact on the population. There are national and international recommendations to verify compliance with the emission limits of electromagnetic radiation. The recommendations define the measurement set-up and ways to evaluate the results. This project aims to implement the measurement set-up and the use of radio frequency spectrum for non-ionizing radiation emissions at the frequency bands of mobile phone technologies following the measurement procedure defined in the standards.Fil: Narvaez, Pablo Rodrigo.

A obra poética de Pablo Neruda: um estudo psicanalítico The Pablo Neruda’s poetic work: a psychoanalytical study
No full textNeste trabalho realizou-se uma leitura da obra poética de Pablo Neruda, conforme os pressupostos teóricos de Freud e Lacan. A preocupação inicial foi a de elaborar um esquema teórico que fornecesse subsídios ao estudo. Num segundo momento foi realizada uma leitura das principais obras que marcam os três períodos literários de Pablo Neruda, tentando-se interpretar psicanaliticamente a rede simbólica encontrada nessas obras. Com base nas análises realizadas, pôde-se observar que a poesia de Pablo Neruda parece possuir um papel de figura objetal, possibilitando ao autor religar-se às suas figuras parentais, nas quais projeta os seus desejos e frustrações.In this work a reading of Pablo Neruda’s poetic work was done, according to a Freud’s and Lacan’s theoretical presuppositions. The first concern was to elaborate a theoretical schema to supply subsidies to this study. After, a reading of the most important works of Pablo Neruda’s three literary periods was done, trying to interpret psychoanalytically the symbolic net of these works. Based on the these analysis, it was observed that Pablo Neruda’s poetry seems to have an object figure role, causing the author to link again to his parents figures on whom he projects his desires and frustrations
Trazas de montea y cortes de cantería en la obra de Rodrigo Gil de Hontañón
No full textRodrigo Gil de Hontañón (1500-1577) es considerado como uno de los arquitectos españoles más importantes del siglo XVI. Hijo del prestigioso cantero Juan Gil de Hontañón, constituye el último representante de la tradición gótica en nuestro país. Su labor se extendió sobre un vasto territorio de la Corona de Castilla, en el que construyó un sinnúmero de edificios religiosos y civiles. Participó en la construcción de dos de las fábricas más destacadas de su tiempo, las catedrales de Salamanca y Segovia. Por otro lado, es autor del más completo manuscrito sobre construcción gótica existente en Europa. Su figura ha sido objeto de numerosos estudios, referidos fundamentalmente a los aspectos históricos de su obra y, en menor medida, a los de teoría del diseño estructural contenidos en sus textos. Sin embargo, son prácticamente inexistentes los que analizan las prácticas empleadas por este maestro de cantería en el trazado y la construcción de sus edificios. Los elementos más relevantes en la obra de Rodrigo Gil, desde el punto de vista del corte de piedras, son, sin duda, las bóvedas de crucería. A ellas se dedica la parte principal de la presente Tesis Doctoral, articulándose en dos categorías. La primera de ellas se refiere a las características geométricas de estas estructuras, analizando, por un lado, su modulación, rangos dimensionales y sistemas de composición en planta, y, por otro, el trazado de sus arcos y de su rampante o línea de espinazo. La segunda investiga las características constructivas de los elementos que las constituyen, examinando sucesivamente sus nervios, jarjas, claves y plementería. El estudio individual y comparativo de un conjunto de 104 bóvedas, realizado bajo los criterios indicados, ha permitido establecer los procedimientos más habituales de montea y labra empleados por Rodrigo Gil, desvelando que, tras sus elaborados diseños formales, se ocultan unas técnicas bastante restringidas, orientadas a simplificar notablemente el trazado, la ejecución y el montaje, y muy eficaces en sus resultados. La construcción de un modelo a escala 1:3 de una de dichas bóvedas ha puesto de manifiesto algunos de estos recursos. Junto a los anteriores, otros elementos arquitectónicos de cantería se encuentran también presentes en los edificios de Rodrigo Gil, tales como arcos, capialzados, pechinas, trompas, escaleras y bóvedas diversas. A ellos se reserva un pequeño apartado. La investigación se ocupa, asimismo, del cuaderno de arquitectura de Rodrigo Gil. Un análisis minucioso ha dado como resultado la identificación de una serie de procedimientos orientados al trazado arquitectónico de un edificio religioso gótico. A continuación se ha seleccionado un conjunto de quince iglesias trazadas por este maestro, a fin de examinar, por una parte, la aplicación práctica de estos criterios de diseño, y, por otra, la de algunas de las ya conocidas reglas para el dimensionado estructural. La comprensión de esta realidad construida se completa con un estudio del contexto histórico y profesional en que Rodrigo Gil desarrolló su actividad, así como una breve reseña histórica de cada uno de los edificios en los que intervino. ----------ABSTRACT---------- Rodrigo Gil de Hontañón: geometric drawing and stonecutting in his work. Rodrigo Gil de Hontañón (1500-1577) is considered one of the most important Spanish architects of the sixteenth century. Son of the prestigious stonemason Juan Gil de Hontañón, he is the last representative of Gothic tradition in Spain. His work expanded over a vast territory of the Crown of Castile, where he built countless religious and civil buildings. He took part in the construction of two of the most noted buildings of his time, the cathedrals of Salamanca and Segovia. Besides, he is the author of the most complete manuscript on Gothic construction in Europe. His figure has been the subject of numerous studies, mainly referring to the historical aspects of his work and, to a lesser extent, to those of structural design theory contained in his texts. However, virtually none of them analyzes the practices used by this master in the design and construction of his buildings. Ribbed vaults are without a doubt the most relevant elements in the work of Rodrigo Gil, from the point of view of stonecutting. The main part of this Doctoral Thesis is devoted to them, and focuses on two categories. The first one refers to the geometric features of these structures, analyzing, on the one hand, their proportion, dimensional ranges and plan layout, and, on the other hand, the design of their arches and ridge. The second one investigates the constructive features of the elements that make them up, examining successively their ribs, tas-de-charges, bosses and web. The individual and comparative study of a set of 104 vaults, carried out under the specified criteria, has enabled to establish the most usual procedures of drawing and cutting utilized by Rodrigo Gil: the analysis has disclosed that rather limited techniques are hidden behind their elaborate patterns, aimed at considerably simplifying vault drawing, execution and erection, and very effective in their results. The construction of a 1:3 scale model of one of these vaults has brought some of these devices to light. Along with the aforementioned ones, other architectural stonework elements are also present in the buildings by Rodrigo Gil, such as arches, arrière-voussures, pendentives, squinches, stairs, and varied vaults. A small section is dedicated to them. Additionally, the research deals with Rodrigo Gil’s architectural booklet. A detailed analysis has resulted in the identification of a series of procedures oriented to establish the architectural layout of a Gothic religious building. Next, a set of fifteen churches designed by this master has been selected, in order to examine the application, on the one hand, of these design criteria, and, on the other hand, of some of the well-known rules for structural sizing. A study of the historical and professional context in which Rodrigo Gil developed his activity, as well as a brief historical review of each of the buildings in which this master took part, is included, for the purpose of complementing the understanding of this architecture

Family altruism and incentives
No full textThe author builds on the altruistic model of the family, to explore the strategic interaction between altruistic parents, and selfish children, when children's efforts are endogenous. If there is uncertainty about the amount of income the children will realize, and if parents have imperfect information, the children have an incentive to exert little effort, and to rely on their parent's altruistically motivated transfers. Because of this, parents face a tradeoff between the insurance that bequests implicitly provide their children, and the disincentive to work prompted by their altruism. The author shows that if parents can credibly commit to a pattern of transfers, they will choose not to compensate children in bad outcomes, as much as predicted by the standard (no uncertainty, no asymmetric information) dynastic model of the family. Alternatively, parents may choose to forgo any insurance, and offer a fixed level of bequest, to elicit greater effort from their children. The optimal transfers structure that the author derives, reconciles the predictions of the altruistic family model, with much of the existing evidence on inter-generational transfers, which suggests that parents compensate only partially, or not at all, for earnings differentials among their children. Moreover, the author shows that Ricardian equivalence holds in this setup, except when non-negativity constraints are binding.Economic Theory&Research,Environmental Economics&Policies,Health Economics&Finance,Educational Sciences,Safety Nets and Transfers

Carta que un amigo escribe a otro: relación poética inédita de la dedicación de la iglesia jesuítica de San Pablo (Lima, 1638)
No full textThe library of the Hispanic Society of America holds a poetic manuscript –likely autograph– that contains an epistle written in octosyllabic form following the pattern of the ballad. The author, who disguises himself with the pseudonym of Menandro, gives an account to a friend of the celebrations and processions organised by the Society of Jesus for the dedication of the church of San Pablo in 1638. The Carta provides us with new information on this temple and the society of Lima at the time. This article offers an introduction and a critical edition of this unpublished text
