Purpose: Three-dimensional finite element analysis was used to evaluate the effect of vertical and angular misfit in three-piece implant-supported screw-retained fixed prostheses on the biomechanical response in the peri-implant bone, implants, and prosthetic components. Materials and Methods: Four three-dimensional models were fabricated to represent a right posterior mandibular section with one implant in the region of the second premolar (2PM) and another in the region of the second molar (2M). The implants were splinted by a three-piece implant-supported metal-ceramic prosthesis and differed according to the type of misfit, as represented by four different models: Control = prosthesis with complete fit to the implants; UAM (unilateral angular misfit) = prosthesis presenting unilateral angular misfit of 100 pm in the mesial region of the 2M; UVM (unilateral vertical misfit) = prosthesis presenting unilateral vertical misfit of 100 pm in the mesial region of the 2M; and TVM (total vertical misfit) = prosthesis presenting total vertical misfit of 100 pm in the platform of the framework in the 2M. A vertical load of 400 N was distributed and applied on 12 centric points by the software Ansys, ie, a vertical load of 150 N was applied to each molar in the prosthesis and a vertical load of 100 N was applied at the 2PM. Results: The stress values and distribution in peri-implant bone tissue were similar for all groups. The models with misfit exhibited different distribution patterns and increased stress magnitude in comparison to the control. The highest stress values in group UAM were observed in the implant body and retention screw. The groups UVM and TVM exhibited high stress values in the platform of the framework and the implant hexagon, respectively. Conclusions: The three types of misfit influenced the magnitude and distribution of stresses. The influence of misfit on peri-implant bone tissue was modest. Each type of misfit increased the stress values in different regions of the system. INT J ORAL MAXILLOFAC IMPLANTS 2011;26:788-796

La investigacin trata de mostrar cuatro acciones habitualmente empleadas al proyectar arquitectura. La tesis narra el discurso que construyen cuatro acciones como mecanismos optimizadores, fundamentales, activos y necesarios cuando creamos nuevos proyectos. En este trabajo se estudian en profundidad cuatro acciones optimizadoras a travs de numerosos casos de estudio. Se estudia tambin la presencia de estas acciones en otros campos creativos, como la biologa, el arte, la literatura, la filosofa, la matemtica o la psicologa de la creatividad. Se busca qu tienen en comn estas cuatro acciones y se indaga sobre la posible narracin que construyen entre ellas. La mayor parte de los textos que constituyen este trabajo se escriben en un formato prximo al del ensayo, empleando tiempos verbales presentes evitando los tiempos verbales pretritos o imperfectos para potenciar la accin a travs el estilo narrativo. La investigacin se ha realizado a partir de fuentes bibliogrficas existentes en numerosas bibliotecas. Se han llevado a cabo estudios de campo realizados a travs de entrevistas personales a interlocutores expertos, no slo de teora arquitectnica sino tambin de prcticas constructivas, as como visitas a lugares ntimamente relacionados con el tema de investigacin. Se ha completado el estudio de casos con ejercicios prcticos realizados por el autor de esta tesis, para profundizar con la propia investigacin por empata con los autores estudiados. La investigacin bibliogrfica principal se ha desarrollado en las bibliotecas de la Universidad Politcnica de Madrid, de la Universidad de Alicante, de la Universidad Autnoma de Madrid, de la Universidad Europea de Madrid, de la Universidad Camilo Jos Cela, de la Universidad Complutense de Madrid, de la Columbia University, de la Harvard University, de la Delft University, de Heidelberg University, de la Biblioteca Central de Madrid y de la Regional de Murcia, as como de la del COAMU. Tambin se ha utilizado recursos bibliogrficos propios. La metodologa utilizada muestra desde diferentes perspectivas el problema de las acciones optimizadoras, desde obras artsticas, pasando por ejemplos de arquitectura construida hasta ejercicios puramente intelectuales. La acumulacin ha sido el mtodo de obtencin de conocimiento de esta tesis. Se han acumulado conocimientos y posteriormente se ha profundizado, reflexionando sobre los datos que se han ido obteniendo. Al profundizar se enlazan unas pruebas con otras, hilando y ensamblndolas en un discurso que hace continuo y coherente la aparicin de cada caso estudiado. Estas entidades probatorias son acciones que han sido aplicadas frecuentemente por distintas generaciones de autores que proyectan utilizando alguna de estas cuatro acciones. Partimos de una extensa bibliografa general y de otra especfica. A travs de citas e imgenes se muestra el repertorio de objetos y textos estudiados. Los casos de estudio seleccionados exponen los efectos que produce cada accin en el ejercicio del proyectar. Se ha estudiado la necesidad de cada accin en todas y cada una de las partes del ciclo creativo del proyecto, tanto en prcticas imaginadas como en construidas, de los autores que proyectan. Se citan y se interpretan las descripciones de bilogos, socilogos, antroplogos, psiclogos, escritores, artistas, arquitectos, matemticos, ingenieros, fsicos, mdicos y filsofos en los cuales estas acciones se encuentran conscientemente incorporadas en su procedimiento de proyectar y de pensar. Por ltimo, hemos obtenido unos resultados adecuados a la metodologa empleada y a los objetivos planteados gracias a la acumulacin y clasificacin de pruebas. Los resultados se exponen a modo de discursos conclusivos con un intencionado carcter abierto que despliega nuevas posibles nuevas vas de investigacin entorno a los temas estudiados. ABSTRACT. The research seeks to show four commonly used actions in designing architecture. Thesis recounts the speech that built four actions like optimizer, fundamental, active and necessary mechanisms when we create new projects. In this work it studies in depth four optimizer actions through numerous case studies. Also, it considers the presence of these actions in other creative fields, such as biology, art, literature, philosophy, mathematics or psychology of creativity. It is intended what these four actions have in common and it explores the possible narrative constructed among them. Most of the texts that constitute this work are written in a format close to the essay, using present tenses avoiding past or imperfect tenses of enhancing the action through the narrative style. Research has been done from literature sources available in numerous libraries. Field studies have been carried out through personal interviews with expert speakers, not just of architectonic theory but also from constructive practices, as well as visits to sites closely related to the research topic. case studies with practical exercises conducted by the author of this thesis has been completed, to deepen with the own research by empathy with the studied authors. Main bibliographical investigation has been developed in the libraries of UPM, UA, UAM, UEM, the CJC, the UCM, Columbia University, Harvard University Delft University, Heidelberg University, Madrid Central Library, Regional Murcia Library and COAMU Library. Also it has been used own bibliographical resources. Methodology shows from different perspectives the problem of optimizers actions, from art, passing through examples of architecture built up to pur intellectual exercise. Accumulation has been the method of obtaining knowledge of this thesis. it has been accumulated knowledge and later it has been deepened, reflecting on the data that have been obtained. By deepening tests are linked with other, spinning and locking into a discourse that makes continuous and consistent the development of each case study. These evidentiary entities are actions that have been frequently applied by different generations of authors who project using some of these four stocks. We leave from an extensive general bibliography and another specific one. Through quotes and pictures it shows the repertoire of objects and texts studied. The selected study cases set out the effects that each action produces in the exercise of projecting. It has studied the need of each action in every parts of creative cycle of the project, both imagined as constructed practices, by the authors who project. It is quoted and interpreted the descriptions of biologists, sociologists, anthropologists, psychologists, writers, artists, architects, mathematicians, engineers, physicists, physicians and philosophers in which these actions are consciously incorporated into his projecting and thinking procedure. Finally, we have obtained adequate results to the used methodology and to the stated objectives through the accumulation and classification of evidence. The results are presented as conclusive speeches with an intentional open character that unfolds new possible research routes around the studied topics.

The analysis of the interdependence between time series has become an important field of research, mainly as a result of advances in the characterization of dynamical systems from the signals they produce, and the introduction of concepts such as Generalized (GS) and Phase synchronization (PS). This increase in the number of approaches to tackle the existence of the so-called functional (FC) and effective connectivity (EC) (Friston 1994) between two, (or among many) neural networks, along with their mathematical complexity, makes it desirable to arrange them into a unified toolbox, thereby allowing neuroscientists, neurophysiologists and researchers from related fields to easily access and make use of them.

Se ensaya aqu cmo construye su mirada el arquitecto Mario Pani Darqui (Mxico, D.F., 1911-1993), cuya visin es la del jugador de ajedrez: estratgica, cenital y transversal, profunda y extraada, inci- siva y extensa, mimtica y contrapuesta. Todo al mismo tiempo. Con base en esta reconstruccin de su forma de ver crucial para el entendimiento de la arquitectura y el urbanismo de Mxico en el si- glo XX se plantea una accin conceptual en el entorno del ro Manzanares en Madrid. Un paisaje espiritual, silente, que a travs de tres situaciones radicales obliga a quien lo contempla a un ejercicio instantneo de meditacin. Se ejecuta y se cartografa, dando como resultado una aproximacin sen- sible sobre cmo intervenir en el paisaje y su registro.
