El trabajo se desarrolla en dos partes. En la primera se sitúa al edificio en su contexto histórico, estudiando sus características tipológicas, constructivas, estado de conservación y valor patrimonial. En la segunda, se plantea una metodología para la evaluación de costos y probables beneficios derivados de la rehabilitación y puesta en valor del edificio analizado 1998-01-01T00:00:00Z http://rodna.bn.gov.ar/jspui/handle/bnmm/327939 Título : Cultural heritage and tourism: possibilities of a sustainable relationship. Descripción : Conservators are generally trained to work on the tangible components of cultural heritage (mainly historic buildings and sites) as a means of preserving their values and meanings and to transmit them to future generations. The Venice Charter establishes, in Article 5, that &ldquo;the conservation of monuments is always facilitated by making use of them for some socially useful purpose. Such use is therefore desirable but it must not change the lay-out or decoration of the building&rdquo;. Tourism plays a prominent role in relation to uses given to cultural heritage; historic monuments and sites are one of the most valuable resources for the development of tourism since they express the identity and cultural traditions of a country, region or town. <em>(P&aacute;rrafo extra&iacute;do a modo de resumen)</em> 2015-10-01T00:00:00Z http://rodna.bn.gov.ar/jspui/handle/bnmm/327937 Título : Regional patterns of ecosystem functional diversity in the Argentina Pampas using MODIS time-series Descripción : The characterization of ecosystem functioning is significant for different purposes such as biodiversity conservation and ecosystem services. A key aspect of ecosystem functioning is carbon gains, since it represents the energy available for upper trophic levels. In this sense, remote-sensing methods have allowed the study of ecosystem dynamics and spatial distribution at different spatial and temporal scales. The objectives were to describe the regional patterns of ecosystem functional diversity and to establish the importance of interannual variability in the definition of Ecosystem Functional Types (EFTs) in the Argentina Pampas. EFTs were obtained from carbon gains using a set of seven functional attributes and their interannual variations, which were retrieved from 14-year NDVI time-series. An ISODATA technique was applied to all the analyzed variables, and the clusters that best separate in the n-dimensional space were selected using discriminant analysis. The Argentina Pampas shows a high heterogeneity in the spatial patterns of ecosystem functional attributes. The annual integral of NDVI (i-NDVI, a linear estimator of net primary productivity), a complex of ecosystem functional attributes that describe the interannual variability, and the annual relative range of NDVI (RREL, ecosystem seasonality) had the highest relevance to distinguish nine EFTs in the study area. This study shows a novel approach for mapping ecosystem functioning, which reveals the importance of interannual variations. This methodology includes the effects of climate variability on ecosystem dynamics, thus enhancing our understanding of ecosystem functional diversity. The results obtained represent a baseline scenario to evaluate the effects of both land use change and climate variability on ecosystem functioning from a temporal perspective. 2018-01-18T00:00:00Z http://rodna.bn.gov.ar/jspui/handle/bnmm/327934 Título : Análisis estadístico de los resultados geoquímicos de los granitos de Cerros Colorados y Aguas Blancas, Sierras Australes de Buenos Aires Descripción : Se realizó un estudio estadístico multivariado por los métodos de Componentes Principales y Análisis Discriminante con los resultados de los análisis químicos de los granitos peraluminosos de Cerros Colorados y Aguas Blancas. Con Componentes Principales, se determinó, que ambos intrusivos son similares, si bien se encontraron algunas diferencias en las variables involucradas. El análisis Discriminante permitió diferenciar los granitos estudiados sólo en base al contenido de $latex SiO_{2}, K_{2}O\hspace {0.1cm} y\hspace{0.1cm} Fe_{2}O_{3}.\hspace{0.1cm}$Los resultados obtenidos coinciden con la génesis deteminada a partir de los datos geoquímicos y petrológicos.; A multivariate statistical analysis (Principal Components and Discriminant Analysis), of chemical data of peraluminous granites of Cerros Colorados and Agitas Blancas was carried out.Principal Components was used to confirm the resemblance between both intrnsives, although there were sorne differences in the involved variables. The discriminant analysis allowed to differenciate the studied granites only by $latex SiO_{2}, K_ {2}O\hspace{0.1cm} y\hspace{0.1cm} Fe_{2}O_{3}\hspace{0.1cm}$ contents. The results agree with the genesis determined from the geochemical and petrological data. 1992-01-01T00:00:00Z
