Análise ambiental simplificada no entorno de águas superficiais na bacia do rio Corumbataí (SP)

The basin of the Corumbataí river is of vital importance to over 600 thousand people, who depend on its waters for consumption. The Simplified Analisys of Environmental Impacts in the Areas Surrounding the Surface Waters of the Drainage Basin of the Corumbataí River (SP) is aimed at defining the areas which are most susceptible to degradation or already damaged and propose engineering solutions according to the environmental problems identified. Using a questionnaire to indicate possible impacts in the surroundings, I related human actions to these damage and quantified them. Having studied the basin extensively and selected 42 areas - generically identified as points and grouped as sub-basins and according to the soil usage -, I was able to identify the main environmental impacts in the basin as: sugar cane monoculture, lack of riparian forest, damaged areas due to mining, the bad state of rural roads and bridges, rubbish disposal alongside roads or directly into the river, accelerated and unplanned expansion of residential and industrial areas into the rural areas and river sources, and Rio Claro's untreated city wastewater

As concepções urbanísticas que impulsionaram o desenvolvimento do capitalismo e a reprodução da força de trabalho em São Paulo: sanear e excluir

This article aims to rank the main concepts in vogue in the city of São Paulo who contributed to the formulation of a shared urban oriented capitalist development and reproduction of the workforce. This way, it will discuss the main issues raised in the period, which is between the first decades of the XX Century to the end of the 1950s, trying to foresee how they worked as engineers and architects to incorporate the urbanistic proposals from Europe and the United States. And then, we will present, on the first four sections of this article, points of view that effectively impacted the paulista urban thought of the first half of the XX century: Sanitarism, pendular conception between the Mesologic Theory and the Microbian Theory; the Historicist formulation of Camillo Sitte; Howard´s garden-town and The French Experience. Our analyses were formulated having as a reference the broad systematization of bibliography and documents performed at the Arquivo Histórico Municipal (Intermediário) de Araraquara (Historical Municipal Archive from Araraquara), consultations at the the books of the library of the biblioteca da Faculdade de Arquitetura e Urbanismo da USP (USP Architecture and Urbanism College) and at the Faculdade de Ciências e Letras da UNESP, Araraquara-SP( College of Sciences and Languages from UNESP, campus Araraquara). The analisys of the performed research show that one urbanistic torrent at São Paulo State with clear influences from the conceptions that led the urbanistic debates in the first half of the XX Century. Although these conceptions compose a painting of urban transformations at São Paulo city and noticeably in some inland cities, previously to the solidification of a whole proposition for the city that was later called of Directive Plan.

Designing a vaccination strategy against dengue

In this work we propose a mathematical approach to estimate the dengue force of infection, the average age of dengue first infection, the optimum age to vaccinate children against dengue in a routine fashion and the optimum age interval to introduce the dengue vaccine in a mass vaccination campaign. The model is based on previously published models for vaccination against other childhood infections, which resulted in actual vaccination programmes in Brazil. The model was applied for three areas of distinct levels of endemicity of the city of Recife in Northeastern State of Pernambuco, Brazil. Our results point to an optimal age to introduce the dengue vaccine in the routine immunization programme at two years of age and an age interval to introduce a mass vaccination between three and 14 years of age.

Factors Associated with Dengue Mortality in Latin America and the Caribbean, 1995-2009: An Ecological Study

In this study, we aimed to estimate the effect that environmental, demographic, and socioeconomic factors have on dengue mortality in Latin America and the Caribbean. To that end, we conducted an observational ecological study, analyzing data collected between 1995 and 2009. Dengue mortality rates were highest in the Caribbean (Spanish-speaking and non-Spanish-speaking). Multivariate analysis through Poisson regression revealed that the following factors were independently associated with dengue mortality: time since identification of endemicity (adjusted rate ratio [aRR] = 3.2 [for each 10 years]); annual rainfall (aRR = 1.5 [for each 10(3) L/m(2)]); population density (aRR = 2.1 and 3.2 for 20-120 inhabitants/km(2) and > 120 inhabitants/km(2), respectively); Human Development Index > 0.83 (aRR = 0.4); and circulation of the dengue 2 serotype (aRR = 1.7). These results highlight the important role that environmental, demographic, socioeconomic, and biological factors have played in increasing the severity of dengue in recent decades.

Taxonomic study on the molluscs collected in Marion-Dufresne expedition (MD55) to SE Brazil: Xenophoridae, Cypraeoidea, mitriforms and Terebridae (Caenogastropoda)

The deep-water molluscs collected during the expedition MD55 off SE Brazil have been gradually studied in some previous papers. The present one is focused on samples belonging to caenogastropod taxa Xenophoridae Troschel, 1852, Cypraeoidea Rafinesque, 1815, mitriforms and Terebridae Morch, 1852. Regarding the Xenophoridae, Onustus aquitanus n. sp. is a new species, collected off the littoral of Espirito Santo and Rio de Janeiro, Brazil, 430-637 m depth (continental slope). The main characters of the species include the small size (c. 20 mm), the proportionally wide shell, the white colour, the short peripheral flange, the oblique riblets weakly developed and a brown multispiral protoconch. This appears to be the smallest living species of the family, resembling in this aspect fossil species. In respect to the Cypraeoidea, the following results were obtained: family Cypraeidae Rafinesque, 1815: Erosaria acicularis (Gmelin, 1791) and Luria cinerea (Gmelin, 1791) had the deepest record, respectively 607-620 m and 295-940 m, although the samples were all dead, eroded shells. Family Lamellariidae d'Orbigny, 1841: a total of three lots were collected, provisionally identified as Lamellaria spp. as the samples consist of only vestigial shells; possibly each lot represents a different species. Family Pediculariidae Gray, 1853: a sample of Pedicularia tibia Simone, 2005 was found, expanding the range c. 1000 km southwards, from Ceara to Espirito Santo. Family Ovulidae Fleming, 1822: Pseudosimnia lacrima n. sp., collected off Espirito Santo, 607-620 m depth, is described here and is mainly characterised by its strong biconic outline, small size (c. 7 mm), and a thick peripheral callus. Family Triviidae Troschel, 1863: Cleotrivia antillarum (Schilder, 1922) is recorded for the first time as deep as 620 m, and its distribution expanded from Rio Grande do Norte to Espirito Santo; Dolichupis akangus n. sp. with rounded outline and c. 15 transverse ribs; D. pingius n. sp. with the outer lip expanded posteriorly and c. 10 ribs. In respect to the mitriform neogastropods, the following species are emphasised: family Costellariidae MacDonald, 1860: Vexillum sp., 607-620 m depth; Turricostellaria amphissa n. sp., 295 m depth; T. jukyry n. sp.; T. apyrahi n. sp., both 790-1575 m depth; T. ovir n. sp., 1200 m depth; Nodicostellaria crassa (Simone, 1995), 240-600 m depth, with extension northwards of the range up to Espirito Santo; Austromitra decresca n. sp., 60-105 m depth. Family Mitridae Swainson, 1829: Subcancilla joapyra n. sp., 295 m depth; S. cf. straminea (Adams, 1853), 607-620 m depth. Family Volutomitridae Gray, 1854: Microvoluta corona n. sp., 1500-1575 m depth. Family Mitromorphidae Casey, 1904: Mitromorpha sama n. sp., 607-940 m depth; M. mirim n. sp., 60105 m depth. Regarding the conoidean Terebridae, this paper is a complement of a previous study. It deals with a new species Terebra assu Simone n. sp., from the Abrolhos Bank, 295 m depth, characterised by its narrow outline, yellowish colour, weak sculpture on the last whorls, and a proportionally broad, paucispiral protoconch. A second finding of Terebra alagoensis Lima, Tenorio & Barros, 2007 expands the geographic range from Alagoas to north Espirito Santo. A discussion on the systematics of the "complex Terebra doellojuradoi" in South American coast is also provided, highlighting the improbability of synonymy between T. leptapsis Simone, 1999 and T doellojuradoi Carcelles, 1953. Differences in size, sculpture, spire angulation, aperture, and mainly in protoconch, indicate specific separations. The presently studied terebrids belong to the "complex Terebra doellojuradoi", which encompasses closely related, deep-water, small species, possessing a relatively high degree of endemicity.

Análise de desconforto térmico local em ambientes cirúrgicos com o uso de manequim, medição de variáveis ambientais e avaliação subjetiva

Na avaliação de conforto térmico em ambientes interiores não basta analisar as condições de conforto para o corpo como um todo, pois há a necessidade de se analisar também as condições de desconforto térmico local. Em ambientes complexos, tais como os ambientes cirúrgicos, onde os membros da equipe cirúrgica ocupam diferentes posições no ambiente e desempenham atividades distintas, a análise de condições de desconforto térmico local torna-se ainda mais premente. No presente trabalho foram analisadas condições de desconforto térmico local devido a assimetrias da temperatura radiante, diferença vertical de temperatura do ar e risco de correntes de ar utilizando manequim, medição de variáveis ambientais e avaliação subjetiva. Resultados da avaliação subjetiva mostraram níveis de insatisfação de até 35 % dos anestesistas e enfermeiros com correntes de ar e de até 85% dos cirurgiões com o calor do foco cirúrgico. Resultados similares foram obtidos a partir da medição de variáveis ambientais e com o uso de manequim. Estes resultados ressaltam ainda mais a grande dificuldade de se prover condições de conforto térmico neste tipo de ambiente. Entretanto, a utilização de diferentes ferramentas de análise pode auxiliar na busca de se prover condições de conforto térmico as melhores possíveis para todos os membros da equipe cirúrgica.

Desarrollo preliminar de descriptores para el análisis sensorial de ajos desecados y liofilizados

El polvo de ajo (Allium sativum L.) es una alternativa para conservar en el tiempo sus propiedades sensoriales y prolongar su vida útil como alimento procesado. En la actualidad, no existe una definición clara de las propiedades sensoriales que caracterizan el ajo ni de las técnicas más adecuadas para su análisis. Los objetivos del presente trabajo fueron estudiar diferentes vehículos y determinar el más apropiado para el análisis sensorial del polvo de ajo, y generar y definir los descriptores para las propiedades sensoriales de olor y flavor de diferentes cultivares deshidratados a través de dos métodos: en estufa a 50°C y por liofilización a -50°C, bajo vacío. Se pretende contribuir a la caracterización de este producto aportando un vocabulario específico y sus definiciones, como así también una metodología sensorial propia. Ocho evaluadores, seleccionados y entrenados de acuerdo con las normas internacionales y con experiencia en análisis sensorial, probaron diferentes vehículos y una vez determinado el más adecuado, desarrollaron el lenguaje descriptivo para los ajos desecados y liofilizados seleccionando por consenso los descriptores que mejor caracterizaban las cultivares, y se definió cada término. Se generaron 31 descriptores simples. Si bien, algunos de los descriptores coincidieron con los publicados en la guía ASTM DS 66 (1996) para ajos frescos, con esta investigación se aportó un amplio número de términos nuevos para la descripción del olor y el flavor de los ajos desecados y liofilizados, los cuales contribuyen a una mejor caracterización sensorial de este producto.

Estudios sobre la transmisión escolar de las memorias de la última dictadura militar

El artículo presenta las diferentes perspectivas que abordan el tema de la transmisión de la memoria de la dictadura en la escuela. Estas perspectivas analizan aspectos diferentes: los vectores de transmisión, las narrativas dominantes en cada momento histórico, los trabajos subjetivos de los actores involucrados, la incidencia del carácter traumático de la última dictadura en los procesos de transmisión. Estos estudios incluyen los análisis de libros de texto y libros de historia de la escuela secundaria, los actos escolares, las efemérides y otras fuentes. En cuanto a la transmisión de la memoria, los estudios existentes permiten formular preguntas que aún siguen sin respuesta, sobre todo las relacionadas con la forma en que esa transmisión se produce y hace posible las reinterpretaciones del pasado
