Abstract: Con el fin de evaluar la factibilidad del uso del biosólido como enmienda orgánica para el establecimiento de vegetación y el control de procesos erosivos superficiales activos, se seleccionó un corte de carretera ubicado sobrela Variante a Caldas (Antioquia). Para darle amarre y cobertura al suelo, se sembraron dos especies vegetales tipo pasto Brachiaria Decumbens y Kikuyo (Pennisetum clandestinum), utilizando biosólido proveniente de la PTAR San Fernando, mezclado con suelo de la zona. Se evaluó el comportamiento de bioindicadores de riesgo ambiental: coliformes totales, coliformes fecales, Salmonella-Shiguella, en las aguas de escorrentía y en el suelo del talud en el tiempo. Ambas especies se adaptaron bien amarrando el suelo; la cobertura fue total y permanente. Los resultados muestran la factibilidad del uso del biosólido como enmienda. Sin embargo, la permanencia de los parámetros microbiológicos medidos durante el tiempo de evaluación evidencia la necesidad de sanitizar el biosólido antes de usarlo, ya que estos patógenos constituyen un riesgo ambiental.

Abstract: En este artículo, se presentan los resultados obtenidos en la remoción de coliformes totales, coliformes fecales y salmonella-shigella, presentes en un licor mixto proveniente de la planta de tratamiento de aguas residuales San Fernando (Medellín, Colombia), mediante el uso de una batería de filtros empacados en zeolita clinoptilolita. La experimentación se desarrolló bajo condiciones controladas de caudal y pH, a temperatura ambiente. Se empleó zeolita natural tipo clinoptilolita la cual se activó con solución salina y secado, se empacó en una batería compuesta por dos filtros, uno de flujo descendente y otro de flujo ascendente, para facilitar el contacto de la solución contaminada y el material adsorbente (zeolita). Se realizaron cinco ensayos independientes y al final de cada uno de ellos se lavó y se activó el material zeolítico antes de comenzar el siguiente. En cada ensayo se tomaron tres muestras. Se encontró que la eficiencia de los filtros bajo las condiciones específicas de dise o fue significativamente alta en la remoción de los patógenos evaluados, y el porcentaje de remoción fue independiente del valor de la concentración a la entrada del filtro. Además, la eficiencia en la remoción de los patógenos evaluados no dependió del tipo de microorganismo. This article displays results obtained when total coliforms, fecal coliforms, and Salmonella shigella were removed from mixed liquor taken from San Fernando waste water treatment plant in Medellín, Colombia, by using a battery of filters packed in zeolite clinoptilolite. Experiments were developed under controlled conditions of flow and pH at room temperature. Natural clinoptilolite-type zeolite was used activated with saline solution and drying; it was packed in a battery consisting of two filters (a downward-flow filter and an upward-flow filter) in order to make contact of contaminated solution and adsorbent material (zeolite) easier. Five independent tests were conducted and zeolite matter was washed and activated at the end of each test before starting the next one. Three samples were taken in each test. It was found that efficiency of filters under specific conditions of design was significantly high when assessed pathogens were removed, and percentage of removal was independent from the concentration value at the filter entry. Besides, efficiency to remove pathogens assessed was not dependent on the type of microorganisms.

The Pedagogy of Visual Discourse: An Analytical Approach to Teaching and Evaluating the Rhetorical Image  [PDF]
Jacqueline Irwin
Art and Design Review (ADR) , 2014, DOI: 10.4236/adr.2014.22003
Abstract:

As the area of visual rhetoric develops and evolves, the approaches that critics take in evaluating images must be scrutinized for the overall exploration of the discipline. Incorporating areas of analytical criticism from rhetoric to aesthetics to design should be combined to create the best possible way of evaluating imagery. By expanding on the traditional analytical approach to rhetorical criticism, this paper explores how the additional understanding of aesthetic and design theory will help the critic to reach a fuller understanding of the image. The twelve major principles of design being line, shape and form, space, texture, value, color, repetition, variety, rhythm, balance, emphasis, and economy are combined to create the strategy of the visual aesthetic that works to compliment the existing rhetorical strategies. The more complete understanding of how visuals are created and how people interpret them will allow for a more complete development of the visual rhetorical approach to communication.

Entre páginas de libros antiguos: la descripción bibliográfica material en México
García, Idalia;
Investigación bibliotecológica , 2008,
Abstract: the cultural value of rare books is reflected in its bibliographical description, which is one way of representing a book as a patrimonial object. however such task requires awareness of the material nature and of the particular forms of production which characterize these books. thus adequate bibliographical representation is a manner of assessing a rare book and leads us to a better understanding of our cultural legacy. this paper helps us to comprehend why the characteristics of descriptive bibliography aid to build the representation of patrimonial value through recuperation of a bibliographical description model which allows to delineate the textual and historical values of rare books as instruments of study and patrimonial control.

Amb l'ànima ferida : el debat dels béns bibliogràfics a Mèxic
García, Idalia
BiD : Textos Universitaris de Biblioteconomia i Documentació , 2012, DOI: 10.1344/105.000001809
Abstract: Objectiu. Analitzar la situació actual que caracteritza el patrimoni bibliogràfic de Mèxic, per determinar les possibles vies d'actuació que permetin garantir la permanència dels objectes custodiats en totes les institucions, públiques o privades. -- Metodologia. Anàlisi històrica de les institucions de custòdia, en especial de la Biblioteca Nacional de México i la seva relació jurídica amb les altres institucions del patrimoni cultural mexicà. Aquesta relació s'estableix per mitjà de la revisió dels textos jurídics per determinar semblances i diferències en el reconeixement del patrimoni bibliogràfic i la valoració corresponent. -- Resultats. L'a llament que s'ha produ t de la Biblioteca Nacional de México en el marc de l'esfera cultural i de la legislació corresponent, no li permet apuntalar projectes d'interès general amb finalitats a llarg termini i de naturalesa patrimonial. Això impedeix que aquesta institució aconsegueixi constituir-se com a capdavantera de polítiques culturals que protegeixin adequadament el llegat bibliogràfic del país.Objective. To analyze the current state of the bibliographic heritage of Mexico in order to identify possible courses of action that might ensure the permanence of objects housed in public and private institutions. -- Methodology. Historical analysis of custodial institutions, in particular that of the National Library of Mexico and of its legal relationship with the other institutions of Mexican cultural heritage. An understanding of this relationship is obtained by reviewing legal documents so as to identify similarities and differences in the recognition afforded the bibliographic heritage and the way in which it is appraised. -- Results. The isolation suffered by the National Library of Mexico within the framework of the wider cultural sphere and the prevailing legislation does not allow it to support heritage projects of general interest and with long-term goals. This is preventing the Library from establishing itself as a leader of cultural policies that might provide adequate protection to the country s bibliographic heritage.
