Conception d’un portail participatif d’information géographique Web pour la mise en valeur des produits forestiers non ligneux d’après leurs potentiels de présence.

Les produits forestiers non ligneux (PFNL) rassemblent toutes exploitations sous couvert forestier. Ils excluent les produits issus de la fibre de bois et des produits de la faune. Le bleuet sauvage est un bon exemple de PFNL. Ces produits sont abondants au Québec. Le bleuet est un exemple de PFNL bien établi avec un niveau de commercialisation structurée de produits frais et de transformation. Au contraire, le marché des champignons forestiers tarde à se développer. À titre de produit agroforestier, les PFNL procurent des biens et services bénéfiques aux communautés productrices. La distribution des PFNL varie en fonction de facteurs géophysiques et bioclimatiques. Dans certaines régions du Québec, des groupes s'efforcent de développer des outils d’analyse et de modélisation spatiale conséquents. La géomatique procure des solutions pratiques pour l’identification et le suivi des PFNL. Entre autres, elle opère des données géospatiales spécialisées sur des systèmes d'information géographique (SIG). Ce projet de maîtrise repose sur la mise en place d’un portail participatif d’information géographique web. Il s'adresse à un large panel d’utilisateurs, notamment aux intervenants impliqués dans le développement durable des PFNL. Il offre la possibilité de visualiser et de manipuler des données spécialisées au cas des PFNL. Il propose de localiser les sites à fort potentiel de présence. Il cherche à intégrer des outils de validation de ces sites. Il tend aussi à procurer des outils qui accompagnent la production des utilisateurs. Le portail introduit des applications d’édition, d’analyse et de modélisations spatiales exclusives à la thématique des PFNL. Il abrite des couches de données interactives et interopérables. L'évaluation du portail passe par l’efficacité de ses applications et la convivialité de ses composantes. Ce rapport décrit et fait la démonstration de chacune d'elle.

Mejorando la visibilidad de sitios web usando tecnología semántica

La visibilidad de una página Web involucra el proceso de mejora de la posición del sitio en los resultados devueltos por motores de búsqueda como Google. Hay muchas empresas que compiten agresivamente para conseguir la primera posición en los motores de búsqueda más populares. Como regla general, los sitios que aparecen más arriba en los resultados suelen obtener más tráfico a sus páginas, y de esta forma, potencialmente más negocios. En este artículo se describe los principales modelos para enriquecer los resultados de las búsquedas con información tales como fechas o localidades; información de tipo clave-valor que permite al usuario interactuar con el contenido de una página Web directamente desde el sitio de resultados de la búsqueda. El aporte fundamental del artículo es mostrar la utilidad de diferentes formatos de marcado para enriquecer fragmentos de una página Web con el fin de ayudar a las empresas que están planeando implementar métodos de enriquecimiento semánticos en la estructuración de sus sitios Web.

Disposición al uso de sitios web de un grupo de organizaciones no gubernamentales (ONG) de Medellín

En la actualidad, en Colombia el uso de los sitios web en las ONG no se ha generalizado y analizar las razones de ello puede llevar a establecer estrategias de orientación hacia su uso como herramienta de comunicación para sus labores -- El presente estudio se realizó para conocer la disposición de las organizaciones no gubernamentales (ONG) afiliadas a la Federación Antioqueña de ONG (FAONG) localizadas en la ciudad de Medellín hacia el uso de sitios web -- El interés central consistió en encontrar las ventajas y desventajas que las mismas encuentran acerca de la adopción de estar presentes en el canal en línea a través del uso de sitios web -- Para ello se partió de una revisión de antecedentes teóricos que exploran la adopción de herramientas digitales en diferentes empresas, definen las ventajas y desventajas de la presencia en línea y encuentran algunos motivadores e inhibidores y el nivel de conocimiento de las entidades en cuanto al uso de internet como canal de comunicación -- Para lograr el objetivo se hizo un estudio exploratorio en el que se aplicaron instrumentos, como entrevistas y encuestas, a un grupo de informantes seleccionados de ONG afiliadas a la FAONG -- Los hallazgos mostraron el interés de las organizaciones de tener un sitio web para comunicar e informar sobre su objeto social y determinar hacia cuál población están enfocadas; también se encontraron falencias en cuanto al conocimiento, el uso y la comunicación con sus públicos frente al manejo adecuado de un sitio web

Iis--integrated Interactome System: A Web-based Platform For The Annotation, Analysis And Visualization Of Protein-metabolite-gene-drug Interactions By Integrating A Variety Of Data Sources And Tools.

High-throughput screening of physical, genetic and chemical-genetic interactions brings important perspectives in the Systems Biology field, as the analysis of these interactions provides new insights into protein/gene function, cellular metabolic variations and the validation of therapeutic targets and drug design. However, such analysis depends on a pipeline connecting different tools that can automatically integrate data from diverse sources and result in a more comprehensive dataset that can be properly interpreted. We describe here the Integrated Interactome System (IIS), an integrative platform with a web-based interface for the annotation, analysis and visualization of the interaction profiles of proteins/genes, metabolites and drugs of interest. IIS works in four connected modules: (i) Submission module, which receives raw data derived from Sanger sequencing (e.g. two-hybrid system); (ii) Search module, which enables the user to search for the processed reads to be assembled into contigs/singlets, or for lists of proteins/genes, metabolites and drugs of interest, and add them to the project; (iii) Annotation module, which assigns annotations from several databases for the contigs/singlets or lists of proteins/genes, generating tables with automatic annotation that can be manually curated; and (iv) Interactome module, which maps the contigs/singlets or the uploaded lists to entries in our integrated database, building networks that gather novel identified interactions, protein and metabolite expression/concentration levels, subcellular localization and computed topological metrics, GO biological processes and KEGG pathways enrichment. This module generates a XGMML file that can be imported into Cytoscape or be visualized directly on the web. We have developed IIS by the integration of diverse databases following the need of appropriate tools for a systematic analysis of physical, genetic and chemical-genetic interactions. IIS was validated with yeast two-hybrid, proteomics and metabolomics datasets, but it is also extendable to other datasets. IIS is freely available online at: http://www.lge.ibi.unicamp.br/lnbio/IIS/.

Localization of ribosomal genes in three Pimelodus species (Siluriformes, Pimelodidae) of the São Francisco River: 5S genes as species markers and conservation of the 18S rDNA sites

Pimelodidae is one of the most representative of Neotropical catfish families. However, these fish are still poorly studied in terms of cytogenetics, especially regarding the application of more accurate techniques such as the chromosomal localization of ribosomal genes. In the present work, fluorescent in situ hybridization with 5S and 18S rDNA probes was employed for rDNA site mapping in Pimelodus sp., P. fur and P. maculatus from the São Francisco River in the Três Marias municipality - MG. The results from the application of the 18S probe confirmed the previous data obtained by silver nitrate staining, identifying a simple nucleolar organizing region system for these species. However, the labeling results from the 5S rDNA probe demonstrated a difference in the number and localization of these sites between the analyzed species. The obtained data allowed inferences on the possible processes involved in the karyotypic evolution of this genus.

Quantification and source identification of atmospheric particulate polycyclic aromatic hydrocarbons and their dry deposition fluxes at three sites in Salvador Basin, Brazil, impacted by mobile and stationary sources

The present work has aimed to determine the 16 US EPA priority PAH atmospheric particulate matter levels present in three sites around Salvador, Bahia: (i) Lapa bus station, strongly impacted by heavy-duty diesel vehicles; (ii) Aratu harbor, impacted by an intense movement of goods, and (iii) Bananeira village on Maré Island, a non vehicle-influenced site with activities such as handcraft work and fisheries. Results indicated that BbF (0.130-6.85 ng m-3) is the PAH with highest concentration in samples from Aratu harbor and Bananeira and CRY (0.075-6.85 ng m-3) presented higher concentrations at Lapa station. PAH sources from studied sites were mainly of anthropogenic origin such as gasoline-fueled light-duty vehicles and diesel-fueled heavy-duty vehicles, discharges in the port, diesel burning from ships, dust ressuspension, indoor soot from cooking, and coal and wood combustion for energy production.

Contaminated sites and brownfield management State of art in Brazil and in Germany

Purpose - The aim of this paper is to briefly present aspects of public brownfield management policies from Brazilian and German points of view. Design methodology approach - The data collection method combined literature and documental research. The bibliography included Brazilian and German literature about brownfield management. The documental research includes Brazilian and German legislation and official documents published by CETESB, the Environmental Company of the State of São Paulo, Brazil. Furthermore, publications of German governmental research institutions have been integrated in the paper. Findings - In Brazil, despite the lack of a federal public policy, the State of São Paulo has approved specific rules to deal with contaminated sites. Topics that could be targets of scientific studies have been identified. Experiences in Germany show that it is essential to have political will and cooperation between the different political levels and technical disciplines. Partnerships between German and Brazilian universities would be welcome as there is a wide range of opportunities for academic post-graduation studies and research focusing on human resources capacitation in environmental management. Originality value - The paper makes an original contribution of exploring an area (brownfield management) that is at the forefront of discussion in academe and industry

Radial variation of anatomical features, wood density and decay resistance in teak (Tectona grandis) from two qualities of growing sites and two climatic regions of Costa Rica

The objective of this study was to show the radial variation of some anatomic characteristics, wood density and natural durability of teak (Tectona grandis L.F.) growing in Costa Rica. Samples of trees 13 years old were obtained from two growing sites (high and low growing) of plantations established in a humid tropical climate (CHT) and dry tropical climate (CST). The variables measured of the fibers as well as for the rays were not affected by the climate or the type of growing site, except for the length of the fibers. The fibers of teak wood from the best growing site were significantly larger. Vessels were found with a greater frequency for the CST but mostly solitary in comparison with the CBT. Average density, maximum density and the variation within the ring presented a light higher magnitude for the CST. The quality of the growing site did not affect these variables. The resistance of fungus attack was similar in the area of heartwood near the pith compared to the heartwood near the sapwood for all the conditions evaluated. Nevertheless, it was observed in some trees a similar resistance of fungus attack for areas of sapwood compared to similar areas of heartwood.

The International LAM Registry: A Component of an Innovative Web-Based Clinician, Researcher, and Patient-Driven Rare Disease Research Platform

Background: A relative friability to capture a sufficiently large patient population in any one geographic location has traditionally limited research into rare diseases. Methods and Results: Clinicians interested in the rare disease lymphangioleiomyomatosis (LAM) have worked with the LAM Treatment Alliance, the MIT Media Lab, and Clozure Associates to cooperate in the design of a state-of-the-art data coordination platform that can be used for clinical trials and other research focused on the global LAM patient population. This platform is a component of a set of web-based resources, including a patient self-report data portal, aimed at accelerating research in rare diseases in a rigorous fashion. Conclusions: Collaboration between clinicians, researchers, advocacy groups, and patients can create essential community resource infrastructure to accelerate rare disease research. The International LAM Registry is an example of such an effort.

Heteroduplex formation and S1 digestion for mapping alternative splicing sites

The identification of alternatively spliced transcripts has contributed to a better comprehension of developmental mechanisms, tissue-specific physiological processes and human diseases. Polymerase chain reaction amplification of alternatively spliced variants commonly leads to the formation of heteroduplexes as a result of base pairing involving exons common between the two variants. S1 nuclease cleaves single-stranded loops of heteroduplexes and also nicks the opposite DNA strand. In order to establish a strategy for mapping alternative splice-prone sites in the whole transcriptome, we developed a method combining the formation of heteroduplexes between 2 distinct splicing variants and S1 nuclease digestion. For 20 consensuses identified here using this methodology, 5 revealed a conserved splice site after inspection of the cDNA alignment against the human genome (exact splice sites). For 8 other consensuses, conserved splice sites were mapped at 2 to 30 bp from the border, called proximal splice sites; for the other 7 consensuses, conserved splice sites were mapped at 40 to 800 bp, called distal splice sites. These latter cases showed a nonspecific activity of S1 nuclease in digesting double-strand DNA. From the 20 consensuses identified here, 5 were selected for reverse transcription-polymerase chain reaction validation, confirming the splice sites. These data showed the potential of the strategy in mapping splice sites. However, the lack of specificity of the S1 nuclease enzyme is a significant obstacle that impedes the use of this strategy in large-scale studies.

Association of Trypanosoma vivax in extracellular sites with central nervous system lesions and changes in cerebrospinal fluid in experimentally infected goats

Changes in cerebrospinal fluid (CSF) and anatomical and histopathological central nervous system (CNS) lesions were evaluated, and the presence of Trypanosoma vivax in CNS tissues was investigated through PCR. Twelve adult male goats were divided into three groups (G): G1, infected with T. vivax and evaluated during the acute phase; G2, infected goats evaluated during the chronic phase; and G3, consisting of non-infected goats. Each goat from G1 and G2 was infected with 1.25 x 10(5) trypomastigotes. Cerebrospinal fluid (CSF) analysis and investigation of T. vivax was performed at the 15(th) day post-infection (dpi) in G1 goats and on the fifth day after the manifestation of nervous system infection signs in G2 goats. All goats were necropsied, and CNS fragments from G1 and G2 goats were evaluated by PCR for the determination of T. vivax. Hyperthermia, anemia and parasitemia were observed from the fifth dpi for G1 and G2, with the highest parasitemia peak between the seventh and 21(st) dpi. Nervous system infection signs were observed in three G2 goats between the 30(th) and 35(th) dpi. CSF analysis revealed the presence of T. vivax for G2. Meningitis and meningoencephalitis were diagnosed in G2. PCR were positive for T. vivax in all the samples tested. In conclusion, T. vivax may reach the nervous tissue resulting in immune response from the host, which is the cause of progressive clinical and pathological manifestations of the CNS in experimentally infected goats.
