Extração, caracterização e aplicação do corante de urucum (Bixa orellana L.) no tingimento de fibras naturais

The increasing demand for natural dyes in place of synthetic ones is justified by the non-toxicity or low toxicity of the former. The synthetic dyes are associated with diseases like cancer as well as when released in the environment takes longer to degrade and the intermediates could be still more toxic. The Annatto (Bixa Orellana L.) is a carotenoid and one of the more important natural dyes used in the food industry. In the form of dye, it represents nearly 70% of the world natural dye production and 90% in Brazil. In the present work, annatto seeds were used of the species peruana paulista, which had nearly 2.1% of bixin. The process of dye extraction with ethyl alcohol showed 4% of dye in the form of powder with particle diameter of 28mm. The extraction process did not alter the chemical composition of the dye, which was confirmed by the electronic spectrum of absorption. Dyeings were carried out with different mordents to study the total colour difference as well as the wash fastness properties and friction fastness properties under wet and dry conditions. The samples treated with copper sulphate showed colour difference but at the same time showed better fastness results. The samples treated with resin (no formaldehyde) did not alter the colour significantly still better the fastness properties. From the results, it could be stated that the resin could be an alternative for heavy metallic mordents

Geoparks in Brazil-strategy of Geoconservation and Development

Within the framework of the potential of geopark development and the interest of the geological community in creating new areas for geoconservation in Brazil, the aim of this contribution is to show the importance of geoscience education as a strategy for both geoconservation and development, and for the success and maintenance of new geoparks. A historical and evolutionary approach to the theme reveals the current status of geoscience education in Brazil and offers a panorama of the challenges inherent in preparing for the creation of new geoconservation areas. Proposals that aim to promote geoconservation and sustainability in Brazil include projects that capitalize on geological heritage and its relationship with local communities, proposals that form partnerships between the government, universities, businesses, and non-governmental organizations for the development of education, and changes in the law specifically aimed at geoconservation. Improvement in the educational system, including Earth science education, is undoubtedly one of the best strategies to promote the preservation of our natural heritage, and a cultural change in education will certainly promote changes in other areas.

Les villages préhistoriques des bords des lacs circum-alpins entre le Ve et IVe millénaire av. J.-C.

Connus sous le nom populaire de palafittes, les habitats préhistoriques construits sur les rives des lacs subalpins du Néolithique à l’aube de l’âge du Fer (entre 5300 et 700 av. J.-C.) offrent des informations exceptionnelles sur l’évolution culturelle d’une importante région européenne, grâce à la préservation remarquable des matériaux organiques, en particulier du bois. À partir de la deuxième moitié du XXe siècle, le perfectionnement des techniques de fouille subaquatiques et de la dendrochronologie permettront la construction d’un schéma chronologique précis pour l’Europe nord-alpine. Les recherches contribueront à des observations d’ordre écologique à l’échelle locale et régionale et à l’identification des rythmes de développement des villages. Sous l’égide de l'UNESCO, les années 2010 verront la constitution d’un inventaire vaste et uniforme des sites préhistoriques des lacs circumalpins, classés Patrimoine culturel mondial en juin 2011.

Aportación de la monitorización mediante redes de sensores y técnicas no invasivas para la conservación preventiva del Patrimonio

La presente tesis doctoral presenta una serie de estudios en el campo del patrimonio basados en metodologías de monitorización mediante redes de sensores y técnicas no invasivas con el objetivo de realizar nuevas aportaciones a la conservación preventiva mediante el seguimiento de los daños de deterioro o la prevención de los mismos. Las metodologías de monitorización mediante el despliegue de redes tridimensionales basadas en data loggers abordan estudios microclimáticos, de confort y energéticos a corto plazo, donde se establecen conclusiones relativas a la eficiencia energética de tres sistemas de calefacción muy utilizados en iglesias de la región centro de la Península Ibérica, abordando aspectos de afección de los mismos en el confort de los ocupantes o en el deterioro de los elementos patrimoniales o constructivos. Se desplegaron además distintas plataformas de redes de sensores inalámbricas procediendo a analizar en esta tesis cuál es la que presenta mejores resultados en el ámbito del patrimonio con el objetivo de una monitorización a largo plazo y considerando aspectos de comunicaciones, consumo y configuración de las redes. Una vez conocida la plataforma que presenta mejores resultados comparativos se muestra una metodología de estudio de la calidad de las comunicaciones en múltiples escenarios de patrimonio cultural y natural con la misma, que servirá para establecer una serie de aspectos a considerar en el despliegue de redes de sensores inalámbricas en futuros escenarios a monitorizar. Al igual que ocurre con las redes de sensores basadas en data loggers, las tareas de monitorización desarrolladas en esta tesis mediante el despliegue de las distintas plataformas inalámbricas ha permitido la detección de numerosos fenómenos de deterioro que son descritos a lo largo de la investigación y cuyo seguimiento supone una aportación a la prevención de daños en los distintos escenarios. Asimismo en el desarrollo de la tesis se realiza una aportación para la conservación preventiva mediante la monitorización con distintas técnicas no invasivas como la termografía infrarroja, las medidas de humedad superficial mediante protimeter, las técnicas de prospección de resistividad eléctrica de alta resolución o la prospección georradar. De este modo se desarrollan distintas aportaciones y conclusiones acerca de las ventajas y/o limitaciones de uso de las mismas analizando la idoneidad de aplicar cada una de ellas en distintas fases de análisis o con distintas capacidades de detección o caracterización de los daños. El estudio de imbricación de dichas técnicas ha sido desarrollado en un escenario real que presenta graves daños por humedad, habiendo sido posible la caracterización del origen de los mismos. ABSTRACT This doctoral dissertation discusses field research conducted to monitor heritage assets with sensor networks and other non-invasive techniques. The aim pursued was to contribute to conservation by tracking or preventing decay-induced damage. Monitoring methodologies based on three-dimensional data logger networks were used in short-term micro-climatic, comfort and energy studies to draw conclusions about the energy efficiency of three heating systems widely used in central Iberian churches. The impact of these systems on occupant comfort and decay of heritage or built elements was also explored. Different wireless sensor platforms were deployed and analysed to determine which delivered the best results in the context of long-term heritage monitoring from the standpoints of communications, energy demand and network architecture. A methodology was subsequently designed to study communication quality in a number of cultural and natural heritage scenarios and help establish the considerations to be borne in mind when deploying wireless sensor networks for heritage monitoring in future. As in data logger-based sensor networks, the monitoring conducted in this research with wireless platforms identified many instances of decay, described hereunder. Tracking those situations will help prevent damage in the respective scenarios. The research also contributes to preventive conservation based on non-invasive monitoring using techniques such as infrared thermography, protimeter-based surface damp measurements, high resolution electrical resistivity surveys and georadar analysis. The conclusions drawn address the advantages and drawbacks of each technique and its suitability for the various phases of analysis and capacity to detect or characterise damage. This dissertation also describes the intermeshed usage of these techniques that led to the identification of the origin of severe damp-induced damage in a real scenario.

Computerized polymorphic marker identification: Experimental validation and a predicted human polymorphism catalog

A computational system for the prediction of polymorphic loci directly and efficiently from human genomic sequence was developed and verified. A suite of programs, collectively called pompous (polymorphic marker prediction of ubiquitous simple sequences) detects tandem repeats ranging from dinucleotides up to 250 mers, scores them according to predicted level of polymorphism, and designs appropriate flanking primers for PCR amplification. This approach was validated on an approximately 750-kilobase region of human chromosome 3p21.3, involved in lung and breast carcinoma homozygous deletions. Target DNA from 36 paired B lymphoblastoid and lung cancer lines was amplified and allelotyped for 33 loci predicted by pompous to be variable in repeat size. We found that among those 36 predominately Caucasian individuals 22 of the 33 (67%) predicted loci were polymorphic with an average heterozygosity of 0.42. Allele loss in this region was found in 27/36 (75%) of the tumor lines using these markers. pompous provides the genetic researcher with an additional tool for the rapid and efficient identification of polymorphic markers, and through a World Wide Web site, investigators can use pompous to identify polymorphic markers for their research. A catalog of 13,261 potential polymorphic markers and associated primer sets has been created from the analysis of 141,779,504 base pairs of human genomic sequence in GenBank. This data is available on our Web site (pompous.swmed.edu) and will be updated periodically as GenBank is expanded and algorithm accuracy is improved.

Prediction of operons in microbial genomes

Operon structure is an important organization feature of bacterial genomes. Many sets of genes occur in the same order on multiple genomes; these conserved gene groupings represent candidate operons. This study describes a computational method to estimate the likelihood that such conserved gene sets form operons. The method was used to analyze 34 bacterial and archaeal genomes, and yielded more than 7600 pairs of genes that are highly likely (P ≥ 0.98) to belong to the same operon. The sensitivity of our method is 30–50% for the Escherichia coli genome. The predicted gene pairs are available from our World Wide Web site http://www.tigr.org/tigr-scripts/operons/operons.cgi.

EIA-RIMA insuficiente como avaliação de impactos ambientais enquanto busca de sustentabilidade urbana: o caso de São Sebastião

O presente trabalho comprova que o atual instrumento EIA-RIMA - Estudo de Impacto Ambiental e seu respectivo Relatório de Impacto Ambiental, é insuficiente enquanto busca de sustentabilidade urbana no Litoral Norte do Estado de São Paulo, especificamente no município de São Sebastião. O método de analise dos EIA-RIMA sempre enfatizam os ganhos econômicos e atenuam os impactos negativos, apesar das fragilidades naturais, estruturais e restrições legais incidentes. A tese comprova que os instrumentos utilizados no âmbito do processo de licenciamento ambiental dos empreendimentos, como a ampliação do porto comercial de São Sebastião, estão pouco comprometidos com o real desenvolvimento sustentável da cidade e região. As especificidades geográficas, sobretudo as facilidades de interface do território terrestre com o marítimo, proporcionadas pelas características naturais do Canal de São Sebastião, sempre ofereceram condições privilegiadas para o abrigo de embarcações, característica decisiva na escolha do lugar como cidade portuária, vinculada aos mais importantes ciclos econômicos do país. Agora, em 2015, está prestes a entrar em um novo ciclo, principalmente com a ampliação do porto comercial, duplicação da rodovia dos Tamoios e da SP-055 e a exploração da camada pré-sal na Bacia de Santos. A região já apresenta todos os problemas de uma ocupação acelerada em um território ambientalmente frágil, localizado em estreita faixa litorânea, composta de um lado pela Serra do Mar e do outro pelo Oceano Atlântico. Se não houver um planejamento urbano e regional que considere as características e capacidade de suporte deste território, a zona costeira entrará em colapso. Saber dosar o uso de suas potencialidades sem esgotá-las será o desafio de nossa geração. Os Estudos de Impactos Ambientais precisam ser aperfeiçoados para que ações mitigadoras alcancem muito mais do que o mínimo, alinhadas a investimentos, tecnologias inovadoras, infraestruturas necessárias e obrigatórias que sejam pensadas de maneira conjunta e cumulativa nas diversas esferas do poder, com efetiva participação pública, caso contrário, o crescente interesse econômico e político tenderá à destruição irreversível do patrimônio histórico e natural deste território. O EIA está se transformando em um poderoso instrumento político de ordenamento territorial que acaba por definir critérios e parâmetros de uso e ocupação, desempenhando uma função que não lhe compete, além de aprofundar o desencontro entre uma vida urbana de qualidade e um ambiente equilibrado em nome do desenvolvimento econômico e a serviço dos interesses privados.
