Curso de Biblioteconomia.Propõe a adoção de uma metodologia para a indexação do acervo de Silvio Knabenn, cidadão de Santo Amaro da Imperatriz em Santa Catarina, visando à representação e recuperação das informações nele contidas, de maneira adequada à sua tipologia e características próprias. O acervo fotográfico de Knabben é composto de imagens que registram o desenvolvimento de uma comunidade ao longo de anos, o que assegura a importância da presente proposta de tratamento técnico do mesmo. O conjunto de fotografias possui valor inestimável como fonte de pesquisa em diversas áreas do conhecimento, possibilitando compreender a evolução de Santo Amaro da Imperatriz. Trata-se de uma pesquisa exploratória e descritiva abordando a importância da indexação de imagens fotográficas, embasado na literatura existente. Indica metodologia de indexação adequada ao acervo fotográfico de Knabenn e a aplica em uma amostra de fotografias. A indexação proposta poderá orientar o uso futuro da metodologia, servindo de guia para aplicação no acervo como um todo. Ao propor um caminho para a execução da indexação dessas imagens, espera-se ter contribuído não só com o mantenedor do acervo, mas com a comunidade de forma geral, possibilitando que as fotografias preservadas por Knabenn passem a ter outro significado, o de fonte de informação. O presente estudo tem como significado maior ressaltar a importância do tratamento técnico da informação, enfatizando a indexação como uma das formas mais diretas de se atingir o proposto, que é dar um sentido ao documento fotográfico.Proposes a methodology for indexing Silvio Knabben collection, Santo Amaro da Imperatriz citizen in Santa Catarina State, aiming at the representation and retrieval of the information contained in it, a better view of their type and characteristics. The photographic collection of Silvio Knabben is composed of images that record the development of a community over the years, which ensures the importance of this proposal Technician and treatment. The set of photographs has invaluable as a source of research in various areas of knowledge, enabling to understand the evolution of Santo Amaro da Imperatriz. This is an exploratory and descriptive research addressing the importance of indexing images, based on existing literature. After defined the methodology to be applied, it will be applied in a sample due to the large number of items that compose the collection, so that in a continuous work, serve as a guide for use in the collection as a whole. To propose a way to implement the indexing of these images, is expected to have contributed not only to the maintainer of the collection, but the community in general, enabling photographs preserved by Silvio Knabben start to have another meaning, the source information. This study is more meaningful to emphasize the importance of technical information processing, emphasizing the index as one of the most straightforward ways to achieve the proposed, which is to make sense of photographic document
The trophic biology of the holothurian Molpadia musculus: implications for organic matter cycling and ecosystem functioning in a deep submarine canyon
No full textMegafaunal organisms play a key role in ecosystem functioning in the deep-sea through bioturbation, bioirrigation and organic matter cycling. At 3500 m water depth in the Nazaré Canyon, NE Atlantic, very high abundances of the infaunal holothurian Molpadia musculus were observed. To quantify the role of M. musculus in sediment cycling, sediment samples and holothurians were collected using an ROV and in situ experiments were conducted with incubation chambers. The biochemical composition of the sediment (in terms of proteins, carbohydrates and lipids), the holothurians' gut contents and holothurians' faecal material were analysed. In the sediments, proteins were the dominant organic compound, followed by carbohydrates and lipids. In the holothurian's gut contents, protein concentrations were higher than the other compounds, decreasing significantly as the material passed through the digestive tract. Approximately 33±1% of the proteins were digested by the time sediment reached the mid gut, with a total digestion rate equal to 67±1%. Carbohydrates and lipids were ingested in smaller amounts and digested with lower efficiencies (23±11% and 50±11%, respectively). As a result, the biopolymeric C digestion rate was on average 62±3%. We estimated that the population of M. musculus could remove approximately 0.49±0.13 g biopolymeric C and 0.13±0.03 g N m?2 d?1 from the sediments. These results suggest that M. musculus plays a key role in the benthic tropho-dynamics and biogeochemical processes in the Nazaré Canyon.<br/

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Possible mechanisms for a marine benthic regime shift in the North Sea
No full textA sharp regime shift from a brittle star Amphiura filiformis dominated state to a burrowing
mud shrimp Callianassa subterranea dominated situation was observed in a region of the North
Sea known as the Frisian Front in the mid-1990s. No indications exist that food levels or other relevant
conditions in this part of the North Sea had changed significantly. However, the new state has
persisted until the present. This could suggest that this regime shift represents a transition between
alternative stable community states. We propose a potential explanation for the existence of 2 stable
states, which agrees with experimental and field observations. We demonstrated experimentally that
sediments inhabited by burrowing shrimps are more susceptible to sediment resuspension by tidal
currents and wave forces than sediments inhabited by brittle stars. Although the burrowing shrimps
apparently thrive under these conditions, successful recruitment of brittle stars may be hampered on
such unstable frequently resuspended sediments. This implies a positive feedback; brittle stars promote
sediment stability, which favors their persistence. We created a model to demonstrate that this
feedback between the benthic community and sediment stability may cause both the shrimp dominated
state and the brittle star dominated state to be stable under the same external conditions
