El profe Cadena, Augusto Alberto Cadena García
No full textEs común que se resalte la vida y logros de personas que han hecho notables contribuciones a algún campo disciplinario, cuando ellas ya no pueden leer tales homenajes por haberse ido. Este no es el caso, y nos alegra que así sea, y que nuestro maestro, el profe Cadena, pueda leer estas líneas. Es un placer poder presentar algunos aspectos que, desde nuestro punto de vista, recogen las contribuciones del Profesor A. Alberto Cadena García al estudio de los mamíferos, o como nos referiremos a él en adelante “el profe Cadena”. Trataremos de cubrir aspectos académicos, docentes y personales, dentro de un contexto cronológico y en concordancia con la intención de presentar este número temático sobre mamíferos, como homenaje a nuestro profe.

Orizzonti mantovani. Spunti e dinamiche paesaggistiche ne L'Illustrissimo di Alberto Cantoni
No full textIn the literary production of Alberto Cantoni, short story writer and novelist between the nineteenth and twentieth centuries, the novel L'Illustrissimo is highly important both because it is the last publication of the author, from Pomponesco, a small town a few kilometers south of Mantua, both because it summarizes in a single text the different nuances and different directions that his writing has taken over the course of his literary career, also due to a writing and processing time that embraces the entire span of years of his career itself. In the foreground, in addition to the numerous and brilliant characters, one of the protagonists is the Mantuan landscape which, not a simple background, becomes a true literary parameter which in different and significant ways affects the purposes and mechanisms of the novel

Three-dimensional Rendering of Cardiac Structures by Using Computed Axial Tomography (CAT) images
No full textLa Tomografía Axial Computarizada (TAC) permite explorar la estructura cardiaca de un paciente. Se propone realizar una herramienta de reconstrucción a partir de imágenes de TAC, basándose en el proyecto desarrollado por los ingenieros Andersson Contreras y Luis López [1] donde implementaron el método de reconstrucción Isosurface. En el desarrollado por María Arango y Laura Guerrero, con asesoría del Ing. Juan Tello, se implementaron dos métodos de reconstrucción. El objetivo es el de escoger al menos dos métodos y comparar los resultados con los de [1]. Para el procesamiento de imágenes de TAC se requiere:
1.Extracción de imágenes: Las imágenes vienen en formato DICOM, un protocolo estándar de comunicación.
2.Pre-procesamiento: Para acondicionar se usan procesos de erosión, apertura y filtrado.
3.Segmentación: Para extraer el área de interés. Se proponen dos técnicas: contornos activos y Otsu multi-nivel.
4.Reconstrucción tridimensional: Se implementa Marching cubes [2], Vol3d [3] y el de [1].
5.Visualización: Una interfaz gráfica visualiza las reconstrucciones y las vistas axial, coronal y sagital.
La validación de la herramienta se hizo mediante una encuesta aplicada a un cardiólogo. De esta se tuvo que la reconstrucción con [2] brinda cierta información en 2 de los 5 pacientes evaluados. Con [3] y [1] no se obtuvieron resultados satisfactorios porque no se reconstruyen los vasos sanguíneos. Se propone investigar métodos de segmentación e implementarlos en [1] y [2] y profundizar en la reconstrucción de vasos sanguíneos.A Computed Axial Tomography (CAT) scan allows to explore the cardiac structure of a patient. It is proposed to carry out a rendering tool from CAT images based on the project developed by engineers Andersson Contreras and Luis Lopez [1], where they implemented the Isosurface rendering method. In the one developed by María Arango and Laura Guerrero, with the assistance of Ing. Juan Tello and, two rendering methods were implemented. The objective is to choose at least two methods and compare the results with those of [1]. For the processing of CAT images, it is required:
1. Extraction of images: The images come in DICOM format, a standard protocol of communication.
2. Pre-processing: Erosion, opening and filtration processes are used for conditioning.
3. Segmentation: To extract the area of interest. Two techniques are proposed: active contours and multi-level Otsu.
4. Three-dimensional rendering: Marching cubes [2], Vol3d [3] and [1] are implemented.
5. Visualization: A graphical interface visualizes the reconstructions and the axial, coronal and sagital views.
The validation of the tool was done through a survey applied to a cardiologist. From this it was necessary that the rendering with [2] provides certain information in 2 of the 5 patients evaluated. With [3] and [1] no satisfactory results were obtained because the blood vessels were not rendered. It is proposed to investigate segmentation methods and implement them in [1] and [2] and to deepen the rendering of blood vessels.

O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaA pretensão desta dissertação intitulada O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes é investigar a relação entre o sentir e o puro pensar, usando como referência a poesia O Guardador de Rebanhos, de Alberto Caeiro, que apresenta de forma evidente o tema; e como este assunto é tratado nas Meditações Metafísicas de René Descartes, também de forma claramente visível. Podemos perceber em ambos os autores, uma diplopia, uma espécie de duplo olhar sobre a relação sentir e puro pensar. No primeiro capítulo vou falar sobre a tese do duplo olhar de Descartes, a respeito da relação sentir e puro pensar na leitura de Merleau-Ponty, salientando a visão de natureza. No segundo capítulo, parto da leitura das três primeiras Meditações Metafísicas para caracterizar a tensão que se pode verificar entre Descartes e Alberto Caeiro quando se referem ao puro pensar. O foco principal de Descartes, nas três primeiras Meditações, é o pensar puro, e neste ponto Alberto Caeiro critica o pensar puro. No terceiro capítulo, analisando as três últimas Meditações, percebe-se que há uma virada no pensamento de Descartes, no qual o autor inverte seu ponto de vista, aproximando-se da idéia de Alberto Caeiro. No quarto capítulo, mostrarei a leitura que outros autores fazem acerca do sentir e do pensar na obra de Alberto Caeiro, mostrando que assim como Descartes, este também ostenta uma diplopia, não do sentir, mas do pensar. The pretension of this work entitled O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes is to investigate the relationship between the feeling and the pure thinking, using as reference the poetry O Guardador de Rebanhos, by Alberto Caeiro, that presents in an evident way this theme; and as this subject is treated in René Descartes' Metaphysical Meditations, also in a clearly visible way. It is possible to notice in both authors, the diplopy, a sort of double look about the relationship between feeling and pure thinking. The thesis about Descartes'double look regarding the relation of feeling and pure thinking, in Merleau-Ponty reading, pointing out the nature vision, will be treated in the first chapter. In the second chapter, I start from the reading of the first three Metaphysical Meditations to characterize the tension that can be verified between Descartes and Alberto Caeiro when they refer to the pure thinking. Descartes' main focus in the first three Meditations is pure thinking and, in this point, Alberto Caeiro criticizes pure thinking. In the third chapter, analyzing the last three Meditations, it is possible to notice that there is an alteration in Descartes' thought, in which the author inverts his point of view, approaching of Alberto Caeiro's idea. In the fourth chapter, I will show the reading that other authors do concerning feeling and thinking in Alberto Caeiro's work, showing that as well as Descartes, this also shows a diplopy, not of feeling, but of thinking
Lobbying for change as a new theory and practice of active citizenship: author interview with Alberto Alemanno
No full textDo you believe that lobbying is a vehicle for representing the interests of some rather than all, meaning its actors can never be a force for good? Alberto Alemanno, author of Lobbying for Change: Find Your Voice to Create a Better Society, might convince you of the contrary. This interview with Barbara Aubin, LSE Public Affairs, reflects on the importance of engaging with our political representatives, holding them accountable and lobbying for the causes we deeply care about as fundamental elements of a healthy democracy
El acceso a la justicia y la falta de proporcionalidad en la fijación del monto para la suspensión de la ejecución en la acción coactiva.
No full textEl presente trabajo investigativo tiene como finalidad primordial elaborar un documento de análisis crítico que permita establecer un anteproyecto de ley reformatoria al artículo 317 del Código Orgánico General de Procesos COGEP, respecto a la suspensión de la ejecución coactiva, a fin de garantizar el principio de
proporcionalidad y acceso gratuito a la justicia, para llevar a cabo eso ha sido necesario dividir el presente trabajo en tres partes una teórica donde se han abordado temáticas sobre la acción coactiva, la suspensión a la ejecución, así como los principios procesales vulnerados; la segunda parte lo integrar un marco
metodológico donde se han utilizado métodos técnicas e instrumentos de investigación que ha permitido diagnosticar el problema y obtener posibles soluciones de entrevistas a personas conocedoras de la materiaLuego de haber realizado una minuciosa búsqueda tanto en los repositorios universitarios de nuestro país y de aquellas que se encuentran en nuestro medio, donde existe la carrera de Derecho, así también en la biblioteca de la Universidad Regional Autónoma de los Andes “UNIANDES - TULCÁN”, en los cuales se ha
evidenciado que no existe un trabajo con el mismo tema al actual, por ser un tema original y novedoso, frente a la vigencia el nuevo Código Orgánico General de Procesos COGE
