Temperature effect on migration of Zn and Cd through natural clay
No full textTo investigate the effect of temperature on effective diffusion coefficients and retardation factors for Zn and Cd, combined diffusion and sequential extraction analyses were conducted at 15 degrees C and 55 degrees C. The effective diffusion coefficients of the metals increased up to ten times according to the increased temperature. On the other hand, the effect of temperature on the retardation factor depended on the retention mechanisms of the metals. The distribution coefficient for Zn, which was mainly partitioned in the carbonate phase, increased up to two times with the increase in temperature. On the other hand, the distribution coefficient for Cd, which was mainly partitioned in the exchangeable phase, was hardly affected by the temperature change. Results of combined diffusion and sequential extraction analysis showed that the effect of temperature on the heavy metals' (Zn and Cd) migration through the compacted natural clay was influenced by the combined effects of the diffusion coefficient and the retardation factor. Additionally, we could also observe the change in retention mechanism for the metals with the change in pore water concentration
Evaluation of decomposition effect on long-term settlement prediction for fresh municipal solid waste landfills
No full textA considerable amount of settlement occurs due to the decomposition of municipal solid waste (MSW) in landfills over a period of years. Therefore, the effect of biological decomposition governs the long-term settlement characteristics of municipal solid waste landfills. In this study, we investigated the long-term settlement characteristics by applying a number of prediction methods to fresh MSW sites and predicting the settlement curves. Most proposed methods, excluding the power creep law, successfully predicted long-term settlement only if accelerated logarithmic compression due to decomposition of biodegradable MSW was included in the settlement prediction
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories

Infecção natural por Leishmania sp. em flebotomíneos capturados no foco de transmissão de Leishmaniose Tegumentar Americana no município de Piçarras, litoral norte do Estado de Santa Catarina e identificação específica do parasito em amostras clínicas e em cepas isoladas de pacientes.
No full textTCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Biológicas. Biologia.As Leishmanioses são doenças infecto-parasitárias causadas por protozoários do gênero Leishmania, que acometem cerca de 12 milhões de indivíduos em 88 países em todo o mundo. A transmissão do parasito ao homem, assim como para outros mamíferos, ocorre através da picada de insetos fêmeas pertencentes a subfamilia Phlebotominae. Devido ao surgimento de novos casos dessa parasitose no norte do Estado de Santa Catarina, um amplo estudo clínico e epidemiológico vem sendo desenvolvido no intuito de minimizar e até eliminar a transmissão do parasito. Assim, o presente estudo objetivou detectar a presença de Leishmania spp. em flebotomíneos capturados na cidade de Piçarras e caracterizar as amostras de Leishmania isoladas de pacientes provenientes dos focos de LTA no litoral norte do Estado. Para tanto, foram capturados nos meses de março, nos anos de 2006 e 2007, em armadilhas luminosas tipo CDC, cerca de 3.000 exemplares de flebotomíneos na cidade de Piçarras, norte do estado de Santa Catarina, pertencentes as espécies Nyssomyia neivai, Lutzomyia migonei e Lutzomyia fisheri, sendo 98% de Ny. neivai. Para pesquisa da infecção natural, 886 fêmeas de Ny. neivai e 23 fêmeas de Lu. migonei foram divididas em 107 pools (102 de Ny. neivai e 5 de Lu. migonei) de aproximadamente 10 indivíduos e submetidos a extração de DNA segundo Collins e colaboradores, 1987. Os iniciadores PhS1 e PhS2 e 150 e 152 foram utilizados para amplificação de DNA de Phlebotominae e o kDNA de Leishmania sp., respectivamente. Todos os 107 pools examinados apresentaram a banda de 220pb específica de Phlebotominae e 11 (9,8%) apresentaram também a banda de 120pb específica de Leishmania sp. A identificação específica dos produtos de PCR foi feita através de Southern Blot usando sondas para Le. braziliensis e Le. amazonensis, conjugadas com peroxidase através do Kit ECL, confirmando a presença de Le. braziliensis nos 11 pools positivos. Para a determinação especifica de Leishmania sp. presente nas amostras de pacientes, foi utilizada a técnica da PCR-RFLP. DNA dos pacientes foram amplificados utilizandose iniciadores 150 e 152 e foram submetidos a digestão com a enzima HaeIII e AvaI, separadamente. Foram testados 124 pacientes, um apresentou padrão de bandas compatível com a espécie Le. amazonensis, os outros 123 apresentaram padrão de restrição igual ao de Le. braziliensis. Estes resultados mostram pela primeira vez a infecção natural de Ny. neivai por Le. braziliensis no Brasil e sugerem a presença de dois ciclos de transmissão da parasitose no estado, devido a confirmação da existência de Le. amazonensis nos pacientes
Study Of Sand Fly Fauna In An Endemic Area Of American Cutaneous Leishmaniasis And Canine Visceral Leishmaniasis In The Municipality Of Espírito Santo Do Pinhal, São Paulo, Brazil.
No full textCanine American visceral leishmaniasis and American cutaneous leishmaniasis (ACL) cases have been recorded in Espírito Santo do Pinhal. The aim of this study was to gather knowledge of the sand fly community and its population ecology within the municipality. Captures were made weekly over a period of 15 months in the urban, periurban and rural areas of the municipality, using automatic light traps. A total of 5,562 sand flies were collected, comprising 17 species. The most abundant species were Nyssomyia whitmani and Pintomyia pessoai in the rural area, Lutzomyia longipalpis and Ny. whitmani in the periurban area and Lu. longipalpis in the urban area. The highest species richness and greatest index species diversity were found in the rural area. The similarity index showed that urban and periurban areas were most alike. Lu. longipalpis was found in great numbers during both dry and humid periods. The presence of dogs infected with Leishmania infantum chagasi in the urban area indicates a high risk for the establishment of the disease in the region. A high abundance of Ny. whitmani and Pi. pessoai in the rural and periurban areas indicates the possibility of new cases of ACL occurring in and spreading to the periurban area of Espírito Santo do Pinhal.105208-1
Author-Illustrator
No full textThis essay investigates the concept author-illustrator by drawing on two influential essays – ‘Death of the Author’ by Roland Barthes and ‘What is an Author?’ by Michel Foucault. By engaging with the key points of debate that emerge from these positions, this essay argues that the notion of author-illustrator is part of a wider discursive field that is embedded in a complex, commodified, multimedia public sphere where the author is paradoxically reinscribed and erased. This environment is changing the nature of the text, authorship, and reader-text interaction, but until now the concept author-illustrator has been largely absent from these discussions
