Testimonios de un Pasado Imperfecto : Vida Cotidiana de Mujeres bajo Dictadura en Valparaíso y Viña del Mar, Chile 1980-1987

Este proyecto de investigación se caracteriza como estudio histórico-etnográfica basado en estudios de casos de la vida cotidiana de nueve mujeres en Valparaíso y Viña del Mar durante la dictadura chilena, analizando el testimonio de los efectos del régimen autoritario en la vida cotidiana de estas mujeres chilenas entre 1980 y 1987. La metodología se radica firmemente en el método etnográfico con entrevistas semi-abiertas y el análisis del discurso de los relatos. En la metáfora de la arpillera (un tapiz anónimo cosido en lona ensamblado a partir de piezas de tela que muestra escenas de la vida cotidiana o protesta la dictadura de Pinochet), trozos y pedazos de experiencia se juntan en el encima de la lona de la historia para dar forma al testimonio de vida la vida cotidiana. Este proyecto se centra en tres aspectos diferentes de la relación entre el Estado autoritario y la vida cotidiana: las técnicas de gobernabilidad (macro), narraciones de silencio y miedo (micro) y trayectorias narrados (espacial), el último inspirado por el ensayo Halbwachs en caminar por la ciudad. Para cerrar, la relevancia del estudio se destaca por el intento de comprender el efecto de un estado autoritario en el sujeto femenino y las respuestas y adaptaciones que las mujeres chilenas adoptaron en la vida privada y pública mediada por la violencia y el miedo bajo dictadura. La dialéctica del acontecimiento y la rutina de la vida cotidiana bajo la dictadura se unen en las memorias narradas, mediada por el presente vivido, lo cual permite una reflexión sobre la cuestión de la alteridad en la sociedad chilena.Este proyecto de investigación se caracteriza como estudio histórico-etnográfica basado en estudios de casos de la vida cotidiana de nueve mujeres en Valparaíso y Viña del Mar durante la dictadura chilena, analizando el testimonio de los efectos del régimen autoritario en la vida cotidiana de estas mujeres chilenas entre 1980 y 1987.

Desarrollo experimental de un elemento constructivo de envolvente, no estructural, a partir de una matriz de plástico reciclado, reforzado con fibras naturales y/o sintéticas

Esta Tesis trata sobre el diseño y desarrollo de un material constructivo de fachada (tras ventilada), empleando plástico reciclado (granza de caucho, de neumáticos fuera de uso) para su elaboración. El uso de materiales reciclados para la elaboración de nuevos materiales constructivos, es a día de hoy, un valor agregado que contribuye tanto a la disminución de desechos tóxicos, como a la fabricación de productos de alta calidad. La investigación partió de la necesidad de comprender qué es un plástico, cómo son producidos, cuáles son los factores que permitían su reciclaje y qué propiedades podrían ser aprovechadas para desarrollar un nuevo material constructivo. En el estado del arte, fueron analizados los aspectos del plástico relacionados a su composición, propiedades, tipologías, producción, consumo, legislación europea y española, reciclaje y valorización energética. Para analizar más profundamente los materiales desarrollados a partir de plásticos reciclados, desde textiles hasta elementos constructivos. Con el conocimiento adquirido mediante este análisis previo, se diseñó una metodología de experimentación, utilizando caucho reciclado y derivados del yeso como agregados, en una matriz de resinas poliméricas reforzada con fibras naturales y sintéticas. Los resultados obtenidos en los ensayos físicos y térmicos, con los elementos producidos, demostraron que el material tiene una excelente resistencia a tensión así como una baja conductividad térmica. Esta investigación, servirá como precedente para el desarrollo de nuevos materiales y sistemas constructivos, utilizando agregados de plástico reciclado, en los procesos de fabricación. Ya que ha comprobado el enorme potencial que ofrecen, creando nuevos materiales, y contribuyendo a reducir la contaminación medio ambiental. "La mayor recompensa de nuestro trabajo no es lo que nos pagan por él, sino aquello en lo que nos convierte". John Ruskin Material compuesto (Composite) de caucho reciclado, fibras y resinas poliméricas. ABSTRACT This thesis deals with the design and development of a new facade construction material using recycled plastic (rubber pellets from used tires) for processing. The use of recycled materials for the development of new building materials, today is an added value which contributes both to the reduction of toxic waste, as well as the processing of products of good quality. The research derives from the need to understand what a plastic is, how they are produced, what the factors that allowed recycling are and what properties can be exploited to develop a new building material. In the prior art, were analyzed plastic aspects related to its composition, properties, typologies, production, consumption, European and Spanish legislation, recycling and energy recovery. To further analyze the materials developed from recycled plastics, from textiles to construction elements. With the knowledge gained from this previous analysis, we designed an experimental approach using recycled rubber and plaster derivatives as aggregates in a polymeric resin matrix reinforced with natural and synthetic fibers. The results obtained in physical and thermal testing, with the elements produced, showed that the material has excellent tensile strength and a low thermal conductivity. This research will serve as a precedent for the development of new materials and building systems, using recycled plastic aggregates in the manufacturing processes. Since it was found the enormous potential, creating new materials, and helping reduce environmental pollution. "The greatest reward of our work is not what we get paid for it, but what they make us."

Linking land cover changes in the subalpine and montane belts to changes in a torrential river.

Channel cbanges are the consequence of cbanges in sediment yield from the slopes and in the connectivity between slopes and channels bccause of distinct land use and climate inJpacts. In Ibis study, we investigated the characteristics and evolution of a short reach in the headwater of the !juez River, central-soutbem Pyrenees. Assessment of a series of sedimentar)' and geomorphic structures confirtned major cbanges to the valley boUom, mainly related to changes in the intensity of human activity. 'The oldest sedimentar)' structure is a terrace leve! located 3 10 4 m above the current alluvial plain. General deforestation, overgrazing and recwring tires in the montane belt ( 1100-1600 m a.sJ.) have led 10 increased soil erosioo and connectivity, and to tbe triggering of debris llows thal have been deposited on the fluvial tmace. Woody fragments from within the debris llows were dated using acceleraror mass spectrOmetry '"e radiocaroon tcchniques (AMS), yielding ages between 1 00 and 115 cal years BP, whicb coincides with tbe period of maximum deforestalion and human density in the Pyrenees. Depopulation and fannland abaodonment since tbe beginning of tbe 2001 oenrury has resulled in generalliJcod natural and artificial reforestation, a shrinkage of the eroded arcas aod a decline in connectivi¡y bdween slopes and the channel. 1be rnost impor1an1 consequence has been cbannel incision and oarrowing, and the development of a sedimed annour !ayer.

Estudo em laboratório do desempenho de concreto asfáltico usinado a quente empregando ligante tipo asfalto-borracha

Pesquisas sobre aplicação de borracha de pneus descartados em pavimentação asfáltica vêm sendo desenvolvidas desde a década de 1960, especialmente nos Estados Unidos e, desde o início da década de 1990, no Brasil, como alternativa para diminuição dos problemas ambientais gerados por estes resíduos sólidos. Esta pesquisa tem por objetivo avaliar o desempenho de três misturas asfálticas do tipo concreto asfáltico usinado à quente: duas empregando teores diferentes de borracha moída e óleo de xisto (CAP 40 + 12% de borracha + 10% de óleo de xisto e CAP 40 + 20% de borracha + 15% de óleo de xisto) e uma convencional. Este estudo faz parte de um programa de pesquisa coordenado pela Escola de Engenharia de São Carlos da Universidade de São Paulo (EESC-USP), Universidade Estadual de Maringá (UEM) e Petrobrás, envolvendo a execução de misturas com borracha e óleo de xisto em trechos experimentais. Foram realizadas dosagens Marshall e ensaios de resistência à tração, módulo de resiliência e fluência por compressão uniaxial estática. Os corpos-de-prova empregados nos ensaios foram moldados no teor ótimo de cimento asfáltico referente a cada uma das misturas. Constatou-se a viabilidade técnica da adição de óleo extensor para a incorporação de borracha de pneus descartados em concreto asfáltico, permitindo a obtenção de resultados satisfatórios quanto aos projetos de dosagem das misturas pelo método Marshall. Com base nos resultados dos ensaios realizados, acredita-se ser viável a execução de trechos experimentais empregando as duas misturas modificadas.

Synthesis of denim waste-based adsorbents and their application in water defluoridation

This study evaluates the application of denim fiber scraps as a precursor for the synthesis of adsorbents for water treatment via pyrolysis and their application in water defluoridation. The best pyrolysis conditions for the synthesis of this novel adsorbent have been identified and a metal doping route with different salts of Al3 +, La3 + and Fe3 + was proposed to improve its fluoride adsorption behavior. Different spectroscopic and microscopic techniques (i.e., FTIR, XPS, XRF, SEM) were used to characterize the precursor and adsorbents, and to analyze the surface interactions involved in the fluoride removal mechanism. Experimental results showed that these adsorbents were effective for fluoride adsorption showing uptakes up to 4.25 mg/g. The Si-O–metal–F interactions appear to be highly relevant for the fluoride removal. This study highlights the potential of denim textile waste as a raw material for the production of added-value products, thus minimizing their associated disposal cost. It also shows the performance of denim textile waste as a precursor of adsorbents for addressing relevant environmental concerns such as fluoride pollution.

Compressive behaviour of a tire recycled steel and textil fiber concrete subjected to fire

The use of rubber aggregates, steel and textile fibres recycled from tires in concrete is a solution that it is being studied by several authors around the world. A few works have been carried out at room temperature but very scarce at high temperatures. This paper presents the results of a research with the aim to evaluate the behaviour at high temperatures of a concrete made with different amounts of recycled textile and steel fibres from tires. The study considered five concrete compositions, with the same water/cement ratio (W/C=0.43), differing only in the type and quantity of fibers incorporated in the mixture. Thus, a reference composition (0% fiber), two compositions with 30 and 70kg/m3 of steel fibers and a composition with 2 and 4kg/m3 of textile fibers from tires were tested. The concrete was tested for a load level of 0.5fcd and different maximum temperature levels (20, 300, 500 and 700ºC).

Nine small scraps of paper used by Pearson to note references to certain articles in the College Books. The notes are brief, for example "Professors' salaries p. 112," and refer to professorship rules, inductions, or salaries. The slips were originally folded into a little packet labeled "References to certain articles in Coll Books." One note was written on a scrap of a letter dated October 1, 1804.

Thaddeus Mason Harris' working documents regarding subject-based library catalog, ca. 1790

Thaddeus Mason Harris, who served as interim librarian of the Harvard College Library in 1787 and as its librarian from 1791 through 1793, is believed to have created these notes while helping compile the library's first printed subject-based catalog. The catalog, Catalogus Bibliothecae Harvardianae Cantabrigiae Nov-Anglorum, was published in 1790 and represented a significant change in approach to the cataloging of the library's collections, which had formerly been cataloged alphabetically. These documents, many of them on small scraps of paper, contain the titles and bibliographic information of books on a range of topics, from "Anatomici" to "Rhetorica."
