Uso de geotecnologias para a análise da dinâmica do uso da terra no município de Santa Rita de Cássia (BA)

Dissertação (mestrado)—Universidade de Brasília, Instituto de Ciências Humanas, Departamento de Geografia, Programa de Pós-Graduação em Geografia, 2014.O avanço da fronteira agropecuária no oeste baiano é uma das principais causas de fragmentação da paisagem nessa região. A realização de estudos capazes de identificar o padrão da cobertura e uso da Terra assim como quantificar e analisar a fragmentação da vegetação proporciona subsídios para o planejamento ambiental. O objetivo desse trabalho é estudar o processo de cobertura e uso da Terra e da fragmentação da paisagem em uma perspectiva temporal no município de Santa Rita de Cássia – BA, a partir do uso de técnicas de geoprocessamento, com o propósito de descrever o seu avanço e fornecer subsídios para o planejamento ambiental. Para alcançar tal objetivo foi elaborado o mapa do uso da terra do município para o ano de 2008, com a utilização das imagens do sensor PRISM/ALOS e a análise multitemporal do uso da terra no recorte temporal de 1988 a 2008 com o auxílio de imagens do sensor TM/LANDSAT 5. Posteriormente foi elaborada a compartimentação morfogenética do município e o mapeamento de padrões de fragmentos da paisagem. A análise multitemporal e a classificação do tipo de cobertura e uso da Terra mostrou que em 1988 as atividades agropecuárias correspondiam a 8,62% da área total do município passando, em 2008, a ocupar 14,9%, em contrapartida a taxa de ocupação da vegetação natural que era de 88% no ano de 1988, passou por um processo de retração ao longo dos anos analisados e chegou ao índice de 81% em 2008. Com a compartimentação morfogenética foi possível averiguar que houve um crescimento da cobertura e uso da Terra em todas os compartimentos ao longo dos anos porém essa taxa foi mais expressiva nos processos erosivos e estáveis. A análise morfológica da paisagem revelou que as áreas de núcleo correspondiam a 85% da área do município em 1988 e durante os anos passou por um processo significativo de redução de sua área chegando a 77% em 2008. A análise da dinâmica da cobertura e uso da Terra em Santa Rita de Cássia mostrou que o município ainda encontra-se bastante preservado devido, principalmente, as suas características morfogenéticas. _____________________________________________________________________________ ABSTRACTThe advance of the agricultural frontier in the west of Bahia is one of the main causes of landscape fragmentation in this region. Conducting studies that identify the pattern of use and land cover and can quantify and analyze the vegetation fragments provides grants for environmental planning. The aim of this work is to study the process of use and land cover and landscape fragmentation in a time perspective in the municipality of Santa Rita - BA, from the use of GIS techniques, with the purpose of describing its progress and provide subsidies for environmental planning. To achieve this goal a map of land use for the municipality was created, for the year 2008, with the use of images from PRISM / ALOS sensor and multitemporal mapping of land use in the time frame from 1988 to 2008 with the aid of images from TM/LANDSAT 5 sensor. After that the morphogenetic partitioning and mapping of the municipality landscape fragment patterns was elaborated. The multitemporal analysis and classification of the type of use and land cover in 1988 showed that agricultural activities accounted for 8.62% of the total area of the municipality. In 2008, this activities were occupying 14.9%, however the rate of occupation of natural vegetation was 88% in 1988, and went through a process of retraction over the years and reached the rate of 81% in 2008. With the morphogenetic partitioning, it was possible to verify that there was a growth in the use and land cover in all compartments over the years but this rate was more significant in erosive and stable processes. Morphological analysis of the landscape revealed that the core areas accounted for 85% of the municipal area in 1988 and has undergone a significant process of reduction of its area reaching 77% in 2008. The analysis of coverage and use of land in Santa Rita showed that the city is still well preserved, mainly due to the morphogenetic characteristics

Nova espécie de Trichodina Ehrenberg, 1830 (Ciliophora: Trichodinidae) encontrada em Rhamdia quelen (Siluriforme: Heptapteridae), Santa Catarina, Brasil

TCC (graduação) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Curso de Engenharia de Aquicultura.O presente trabalho foi desenvolvido no Laboratório de Patologia e Sanidade de Organismos Aquáticos – AQUOS, durante o período de março de 2011 a março de 2012. No Brasil ainda se tem pouco conhecimento sobre espécies de tricodinídeos que parasitam, tanto peixes de cultivo, quanto peixes selvagens, continentais ou marinhos. Com o desenvolvimento da aquicultura, tais estudos servirão para a manutenção de um cultivo produtivo e sustentável. Este estudo descreve Trichodina n. sp. encontrada no muco da superfície corporal e nadadeiras de jundiá (Rhamdia quelen), selvagens e de cultivo, no sul do Brasil. Foram capturados 137 peixes no município de Paulo Lopes, estado de Santa Catarina, provenientes de três pontos distintos, sendo eles uma piscicultura local (n=80), ponto não poluído do Rio da Madre (n=32), e outro poluído do mesmo rio (n=25). Esfregaços do muco foram secos à temperatura ambiente e impregnados com Nitrato de Prata para posterior análise das estruturas do disco adesivo e dentículos. A prevalência foi de 64% no local poluído, 50% no local não poluído e 21,25% na piscicultura. Caracterizado como médio tricodinídeo apresentou diâmetro do corpo de 54,4 ± 3,7 μm, disco adesivo de 45,3 ± 3,8 μm, anel denticulado 27,3 ± 2,7 μm e 20 a 22 dentículos. Dentículo com 8,4 ± 0,55 μm, lâmina com 4,3 ± 0,5 μm, raio com 6,7 ± 1,32 μm de comprimento e parte central com 3,8 ± 0,55 μm; curvatura da ciliadura adoral com 367º. Trichodina n. sp. apresentada neste estudo é ligeiramente semelhante à T. heteredentata e T. acuta no que se refere às características biométricas, porém difere da primeira principalmente por não apresentar apófise do raio e da segunda por não possuir círculo central. Além disso, com formato da lâmina distinta, Trichodina n. sp. difere de todas as outras espécies já descritas, não deixando nenhuma dúvida de que se trata de uma nova espécie

Coin and Identity: The Provincial Roman Coinage, a Brief Case Study of Tel Dor’s Coins

Through the study of a few coins made at the city of Tel Dor in today s State of Israel during Roman imperial time we will explore questions related to local identities and how they influenced iconographic representations on coins Therefore the coin would hold in itself not just monetary value but also identity value known only by the locals familiarized with the symbols represented on these coins With the analysis of the relationship between coins and identities in this case specifically from Tel Dor we are able to catch a glimpse of the interactions and perceptions of different people under Roman rule and how Romans themselves saw and were seen by those peopl

Potential targets for the hepatitis C virus-mediated autoimmune thyroiditis

Introduction: The mechanisms by which hepatitis C virus (HCV) infection induces autoimmune thyroiditis (AIT) have been studied, and it was suggested that inflammatory cytokines during HCV infection would change the thyroperoxidase (TPO) signaling cascade and thyroglobulin (Tg) determining autoimmune thyroid disease. Objective: To show the signaling pathway, of TPO and Tg, and their potential targets mediated HCV in individuals with hepatitis C. Methods: The mapping of the signaling pathway was based on a review study approach and performed using the automatic annotation server of the Kyoto and Genome Encyclopedia (KEGG). PathVisio is free software for analysis and design of open source routes, and was used for the graphic representation of the signaling pathway. Results: The contigs were extracted from the KEGG database and their mapped transcription represents the signaling pathway of the main biomolecules that triggers the AIT. The action of HCV or its treatment can trigger AIT that is characterized by the presence of autoantibodies against TPO and Tg. In AIT, autoreactive CD4 + T lymphocytes recruit B cells and CD8 + T cells in the thyroid. The progression of the disease leads to the death of thyroid cells and hypothyroidism. Conclusion: HCV or its treatment activates several signaling pathways with thyroid cells damage resulting in AIT and secondary hypothyroidism to cellular apoptosis

“Incidentalormones” - Macro-hormones

Introduction: Complexes of monomeric hormone molecules immunoglobulin-associated lead to the formation of macro-complexes biologically inactive that are called macro-hormones. Patients’ presenting unexpectedly elevated hormones values indicates the need that the existence of macro-hormones must be researched. Objective: To describe the macro-hormones discovered incidentally in laboratory tests, which we refer to as "incidentalormones". Methods: An integrative review was conducted, and data was gathered from the published articles in medical database. The different forms of macro-hormones are reviewed; the biochemical significance and laboratory assays of macro-hormones are also revised within the ambit of current laboratory medicine. We discussed diagnostic difficulty encountered in patients with "incidentalormones”, as well as methods of macro-hormone detection, immunoglobulin involved, clinical significance and associations with other diseases. Conclusion: The presence of macro-hormones, often guides us to intervention in laboratory trials, and could result in false-positive diagnosis with inadequate therapy. Laboratories should follow a diagnostic algorithm to carefully recognize and examine possible immunoassay interferences

Inked careers : tattooing professional paths

The concept of career has an interdisciplinary and historical constitution, which includes persons, groups, organizations and society. Given that, we aim to deepen the interactionist notion of career from the understanding of a deviant path, supported by a theory and a method appropriated to the cited call for interdisciplinary approaches. Dilemmas (Hughes, 1958) and conflicts (Hughes, 1937) emerged as important analytical categories. Although necessary, these two concepts were not sufficient to contemplate analyses in their entirety. For this reason we conceptualized a third possibility of controversy during a career: the inquiries. The study followed the Narrative method to analyze objective and subjective changes during a tattoo artist’s career through interviews and informal conversations carried out over 22 months. The discussion presents three main contributions. Theoretically, a new understanding of the concept of careers, linking past, present and future and the idea of non-linearity of experienced and envisioned careers. Methodologically, suggesting orientations for future career studies such as the use of turning points as a methodological tool and the investigation of deviant fields. Finally, our defense of the interactionist perspective as suitable for career studies, since it allows the investigation of deviant elements

ENVIE Co-ordination action on indoor air quality and health effects; WP3 Final report – Characterisation of spaces and source

Human exposure to environmental pollutants occurs via various pathways. For many pollutants, especially the volatile ones, air exposure is the dominant pathway. Exposure via air occurs both outdoors and indoors, with diverse types of indoor spaces playing a role, e.g., home, workplace, and passenger cabins of means of transportation. In average people spend over 90% of their time indoors, that percentage being particularly high for some specific groups as new-born, elderly, disabled or sick people. The global exposure to air contaminants is therefore drastically determined by indoor conditions. It is now well established that indoor air pollution contributes significantly to the global burden of disease of the population. For a majority of indoor air contaminants, particularly in the presence of common indoor sources, however, indoor concentrations usually exceed outdoor concentrations, for some pollutants even with an indoor/outdoor ratio of 10 or 20. Emissions are identified, accordingly to the EnVIE approach and grouped into four categories: building materials and related sources, including dampness and moulds; ventilation, natural and mechanical, including, or not, heating, cooling and humidification/ dehumidification; consumer products, furnishing, cleaning and household products; and occupant activities. Emission of chemical substances from construction materials and products in buildings to the indoor air have been reported and reviewed for a wide range of substances, including those formed during secondary reactions, causing complaints of irritation and odour. During the last two decades there has been increasing advances in construction technology that have caused a much greater use of synthetic building materials. Whilst these improvements have led to more comfortable buildings, they also provide indoor environments with contaminants in higher concentrations than are found outside. Wood and cork are now frequently used as a building product for floor coverings, because the material is often regarded as “natural” and “healthy”. However, industrial products, even based on natural raw materials, may contain a number of artificial ingredients and the chemical emissions will strongly depend on the type of additives and the manufacturing process. Modern interior paints are usually based on a polymeric binder. In order to fulfil requirements on e.g., durability, paint contains various functional chemicals. Water-borne paints usually also contains small amounts of approved biocides. Polymeric binders with a very low content of residual monomers have been developed for paint. Besides the release of substances to the indoor air due to primary emission, damp building materials may give rise to volatile substances formed during secondary reactions. Semi-volatile organic compounds (SVOCs) are now receiving much more attention than heretofore. The HVAC (Heating, Ventilation and Air Conditioning) systems as providers, among others, of services of cleaning and dilution of pollutants in the indoor air are also recognized as potential pollution sources. Several studies have shown that the prevalence of SBS symptoms is often higher in air conditioned buildings than in buildings with natural ventilation. 8 The outdoor air introduced indoors through either ventilation systems or natural means is also an important and not always controllable source for the intake of some outdoor pollutants. Outdoor air used for ventilation may also be source of pollution containing particulate matter, particulates of biological origin (microorganisms, pollen, etc.) and various gases like NOx and O building structures which is a driving force for the airflows which will transport to indoors water vapour and gaseous or particulate contaminants. Volatile organic compounds are emitted from a wide variety of household and consumer products with emission rates that are strongly dependent on the type of application and are distributed over several orders of magnitude. A number of product classes are identified and information on ingredients and available data on emissions from individual products are presented. Human activities and the associated use of products encompass a wide range of indoor sources involving release of inorganic gases, particles and organic compounds as a consequence of the activity. For some releases such as with air fresheners the release is a necessary part of the activity to achieve the intended effect whereas for others, such as the release of combustion fumes from a gas appliance, the purpose of the action (in this case generation of heat) is different from the emission. Combustion processes are an important source of a range of air pollutants as carbon monoxide, nitrogen dioxide, sulphur dioxide, particulates and associated inorganic and organic chemicals, organic vapours e.g. formaldehyde, acetaldehyde, and benzene. Sources of these are present in both ambient and indoor environments. The concentrations present in the ambient air provide a baseline for the level of pollutant found indoors as this air enters indoors by processes of infiltration and ventilation. However, the concentration indoors will be modified by processes of sorption to surfaces and chemical reaction depending on the chemical and physical properties of the pollutant and internal surfaces. People themselves are a source of emissions of chemicals and gases, notably CO range of organic compounds that are referred to as body odours. The removal of such body odours is a prime objective of ventilation in order to achieve a satisfactory indoor environment. WP3 aims at to characterize spaces and sources in order to understand where and how to act to guarantee good IAQ. From the two strategies for good IAQ, source control and ventilation, the precautionary principle suggests that first priority shall be given to source control, avoiding, mitigating or simply managing sources of emissions. An overview of all policies on IAQ or related to IAQ, existing or in preparation, directly related to indoor air sources, but also covering outdoor air and industrial emissions, which could affect indirectly IAQ is made. Considering the presented it could be concluded that IAQ is yet poorly regulated at EU level, and in view of that some recommendations are made. The recommendations on policies have taken into account the existing related to IAQ policies such as new EU policies on chemicals (REACH; 2006/121/EC), consumer products (GPSD; 2001/95/EC), construction products (CPD; 89/106/EC) and energy performance of buildings (EPBD; 2002/91/EC) all refer to IAQ issues - suggesting that they could, and probably should, contribute to IAQ policy development and advocate an integrative and comprehensive policy approach centred
