Dilemas do planejamento e da gestão municipal na Amazônia ribeirinha: uma análise do caso de Cametá à luz do ideário da reforma urbana e do Estatuto da Cidade

Trata a presente pesquisa de um estudo que discute os instrumentos de reforma urbana concebidos no Estatuto da Cidade relacionados às especificidades sócio-espaciais de um município ribeirinho amazônico. Busca-se identificar e analisar o ideário de reforma urbana proposto pelo Movimento Nacional pela Reforma Urbana (MNRU) e concebido no Estatuto da Cidade atentando para as especificidades sócio-espaciais do Município de Cametá, Estado do Pará. Para a realização da pesquisa recorreu-se a uma abordagem histórico-dialética sobre a problemática enfocada e se utilizou, como procedimentos de pesquisa o levantamento e a análise bibliográfica e documental (Estatuto da Cidade e Plano diretor de Cametá); aplicação de entrevistas semi-estruturadas junto à equipe elaboradora do plano diretor municipal, junto aos integrantes de movimentos sociais urbanos e rurais e junto ao poder público. Por meio da análise, concluiu-se que municípios ribeirinhos como Cametá, em virtude de apresentarem especificidades sócio-espaciais no contexto amazônico e brasileiro, enfrentam dilemas relacionados ao planejamento e à gestão urbana e municipal, distanciando-se, algumas vezes, das diretrizes e princípios estabelecidos genericamente para o território nacional. Tal questão revela a importância de pensar a diversidade sócio-espacial brasileira e amazônica, bem como a necessidade de viabilizar adequações de instrumentos e preceitos que buscam nortear as diversas práticas de planejamento e de gestão em nível local, não obstante os avanços relacionados a essas mesmas práticas nos últimos anos no Brasil.

O Monolinguismo do Outro O caso do poeta politradutor Armand Robin

Este trabalho aborda a questão da pulsão politradutória mediante a análise de sua manifestação na obra do poeta tradutor bretão Armand Robin (1912 - 1961). Essa pulsão, vinculada a uma visada metafísica na obra de Antoine Berman (A prova do estrangeiro, 2002) - definida como a busca romântica da língua pura -, é reavaliada atentando para os aspectos filosóficos e psicanalíticos mais evidentes. Em consonância com a teoria de Jacques Derrida (Le monolinguisme de l'autre, 1996), este estudo sugere que o politradutor Robin - que traduziu poemas de aproximadamente vinte e duas línguas para o francês - na verdade não"tinha" várias línguas, não era plurilíngue no sentido que convencionalmente conhecemos, mas tinha apenas uma língua e que não era a sua. O fato de considerar este poeta como um monolíngüe afásico singulariza e redimensiona a problemática em torno da pulsão do traduzir: a repetição do gesto tradutório desvela o excesso da busca de outras línguas, o que aponta paradoxalmente para um modo de velar o trauma relacionado à língua materna afásica (no sentido derridiano do termo). Esse duplo gesto de pulsão-repulsão se manifesta no poliglotismo e na politradução: traduzir permanentemente permite que Robin suporte na paixão a dor da abdicação de escrever a própria obra.

Infância e escola: desafios no ingresso da criança no ensino fundamental

In order to expand educational services in the country, were recently approved laws that changed the organization of schools and the population served by them, as was the case of Law No. 11.274/2006 elementary school that extended from eight to nine years, establishing the admission of children to this level of education to 6 years old. The research aimed to analyze the relationship between the legal text and the meanings of schooling and the specifics of childhood with the entry of children in elementary school. We proceeded to carry out theoretical research and documentation and with the main results we can state that: 1) referring to the childhood and school education, we can reflect on the period that includes the ages between 5 and 7 years, periods in which the child Brazil, according to new legislation can be met in kindergarten and compulsory from 6 years in elementary education, refers to the student at a time conducive to the psychological and cognitive investment in the development of imagination, thought through images, perception , logical reasoning, comparison and identification of elements of the property, creativity and playful and symbolic creations, 2) found that the formation of the 1st child. years of elementary school students is directed around the practices of literacy, with emphasis on the acquisition of reading and writing; Find out what this new educational context, schools are presenting great challenges due to the specifics of care for children six years in the first year Elementary School, showing gap between the law and the actual developments in the reorganization of schools.

Molekularbiologische Charakterisierung der beiden Untereinheiten des Mega-Hämocyanins der Schnecke Melanoides tuberculata

Bei dem 2010 von unserer Arbeitsgruppe entdeckten Mega-Hämocyanin handelt es sich um einen stark abgewandelten Typ des respiratorischen Proteins Hämocyanin, bestehend aus zwei flankierenden regulären Dekameren und einem zentralen Mega-Dekamer. Diese sind aus zwei immunologisch verschiedenen Untereinheiten mit ~400 bzw. ~550 kDa aufgebaut, die in unserer Arbeitsgruppe bereits proteinbiochemisch charakterisiert wurden. Im Zuge dieser Untersuchungen konnte zudem eine 3D-Rekonstruktion des Oligomers (13,5 MDa) mit einer Auflösung von 13Å erstellt werden. Das Ziel der vorliegenden Arbeit war die Aufklärung der Primärstruktur beider Polypeptide bei der Schnecke Melanoides tuberculata (MtH). Es gelang, die cDNAs der beiden Untereinheiten vollständig zu sequenzieren. Die zu typischen Dekameren assemblierende MtH400-Untereinheit umfasst 3445 Aminosäuren und besitzt eine theoretische Molekularmasse von 390 kDa. Nach dem Signalpeptid von 23 Aminosäuren Länge folgen die für Gastropoden-Hämocyanine typischen funktionellen Einheiten FU-a bis FU-h. Insgesamt verfügt die MtH400-Untereinheit über sechs potentielle N-Glykosylierungsstellen. Die MtH550-Untereinheit, welche mit 10 Kopien das Mega-Dekamer bildet, umfasst 4999 Aminosäuren und besitzt eine theoretische Molekularmasse von 567 kDa. Damit handelt es sich bei dieser Untereinheit um die zweitgrößte jemals bei einem Protein detektierte Polypeptidkette. Die MtH550-Untereinheit besteht aus einem Signalpeptid von 20 Aminosäuren Länge und den typischen Wand-FUs (FU-a bis FU-f). Daran anschließend folgen sechs weitere Varianten der FU-f (FU-f1 bis FU-f6). Die MtH550-Untereinheit verfügt über insgesamt zwölf potentielle N-Glykosylierungsstellen. Anhand der ermittelten Primärstrukturdaten wird klar, dass der auffällig vergrößerte Kragenbereich des Mega-Dekamers aus je 10 Kopien der FU-f1 bis FU-f6 besteht. Die ermittelten Sequenzdaten der beiden MtH-Untereinheiten weisen im Vergleich zu anderen Hämocyanin Sequenzen einige sehr charakteristische Indels sowie unübliche N-Glykosylierungsstellen auf. Es war zudem möglich, anhand einer molekularen Uhr den Entstehungszeitpunkt des Mega-Hämocyanins zu datieren (145 ± 35 MYA). Sowohl die Topologie als auch die berechneten Trennungszeitpunkte des an allen Verzweigungen gut unterstützten Stammbaums stimmen mit den bisher publizierten und auf Hämocyanindaten basierenden molekularen Uhren überein.

Age in antiretroviral therapy programmes in South Africa: a retrospective, multicentre, observational cohort study.

BACKGROUND As access to antiretroviral therapy (ART) expands, increasing numbers of older patients will start treatment and need specialised long-term care. However, the effect of age in ART programmes in resource-constrained settings is poorly understood. The HIV epidemic is ageing rapidly and South Africa has one of the highest HIV population prevalences worldwide. We explored the effect of age on mortality of patients on ART in South Africa and whether this effect is mediated by baseline immunological status. METHODS In this retrospective cohort analysis, we studied HIV-positive patients aged 16-80 years who started ART for the first time in six large South African cohorts of the International Epidemiologic Databases to Evaluate AIDS-Southern Africa collaboration, in KwaZulu-Natal, Gauteng, and Western Cape (two primary care clinics, three hospitals, and a large rural cohort). The primary outcome was mortality. We ascertained patients' vital status through linkage to the National Population Register. We used inverse probability weighting to correct mortality for loss to follow-up. We estimated mortality using Cox's proportional hazards and competing risks regression. We tested the interaction between baseline CD4 cell count and age. FINDINGS Between Jan 1, 2004, and Dec 31, 2013, 84,078 eligible adults started ART. Of these, we followed up 83,566 patients for 174,640 patient-years. 8% (1817 of 23,258) of patients aged 16-29 years died compared with 19% (93 of 492) of patients aged 65 years or older. The age adjusted mortality hazard ratio was 2·52 (95% CI 2·01-3·17) for people aged 65 years or older compared with those 16-29 years of age. In patients starting ART with a CD4 count of less than 50 cells per μL, the adjusted mortality hazard ratio was 2·52 (2·04-3·11) for people aged 50 years or older compared with those 16-39 years old. Mortality was highest in patients with CD4 counts of less than 50 cells per μL, and 15% (1103 of 7295) of all patients aged 50 years or older starting ART were in this group. The proportion of patients aged 50 years or older enrolling in ART increased with successive years, from 6% (290 of 4999) in 2004 to 10% (961 of 9657) in 2012-13, comprising 9% of total enrolment (7295 of 83 566). At the end of the study, 6304 (14%) of 44,909 patients still alive and in care were aged 50 years or older. INTERPRETATION Health services need reorientation towards HIV diagnosis and starting of ART in older individuals. Policies are needed for long-term care of older people with HIV.

Organic carbon in waters, suspended matter, and upper layer bottom sediments of the Kara Sea and Obskay Guba

Along three sections in the Kara Sea and Obskaya Guba concentrations of dissolved and particulate organic carbon (DOC and POC, respectively) in waters , as well as of organic carbon in bottom sediments (Corg) in September-October 2007 were determined. DOC varied from 6.3 to 2400 µg/l, POC - from 0.84 to 12.2 mg/l. For all samples the average DOC was 200 µg/l (n = 78; sigma = 368), the average POC - 2.7 mg/l (n = 92; sigma = 2.7). Concentrations of Corg in dried samples of upper layer bottom sediments varied from 0.13 to 2.10% (aver. = 0.9%; n = 21; sigma = 0.49%). It is shown that distribution of different forms of organic matter (OM) is an indicator of supply and scattering of particulate matter in the Kara Sea and that DOC and POC of the Kara Sea are formed under impact of runoff of the Ob and Yenisei Rivers. It is found that distribution of OM in bottom sediments is closely related to their grain size composition and to the structure of currents in the area. Variations in Corg concentration in bottom sediment cores from the zone of riverine and sea water mixing represent variability of OM burial.

Primary production and chlorophyll a in waters of the Kara Sea in September 2007

These studies were performed from September 10 to 29, 2007 in the Kara Sea in transects westward of the Yamal Peninsula, near the St. Anna Trough, in the Ob River estuary (Obskay Guba), and on the adjacent shelf. Concentration of chlorophyll a in the euphotic layer varied from 0.02 to 4.37 µg/l, aver. 0.76 µg/l. Primary production in the water column varied from 10.9 to 148.0 mg C/m**2/day (aver. 56.9 mg C/m**2/day). It was shown that frontal zones divided the Kara Sea into distinct areas with different productivities. Maximum levels of primary production were measured in the deep part of the Yamal transect (132.4 mg C/m**2/day) and the shallow Kara Sea shelf near the Ob River estuary (74.9 mg C/m**2/day). Characteristics of these regions were low salinity of the surface water layer (19-25 psu) and elevated silicon concentration (12.8-28.1 µg-atom/l). It is explainable by river runoff. Frontal zones of the Yamal current within the Yamal and Ob transects showed high assimilation numbers reached to 2.32 and 1.49 mg C/mg Chl/hr, respectively; they were maximal for studied areas.
