Uso do modelo de simulação 'ABC 6' para avaliação de áreas sujeitas à ocorrência de ondas de cheia e corridas de massa/detritos: estudo de caso na bacia do Ribeirão da Prata (SP)

Pipelines are linear engineering works, designed mostly for transporting oil and its derivatives for long distances, furnishing even the farthermost zones of the country. Due to oil sector needs to ensure for the safety and conservation of its properties, several geotechnical studies are being held at the pipelines field, in order to preserve this important transportation, and also to prevent accidents, which might seriously compromise the environment and the population who lives around it. The OSBRA pipeline, who connects the city of Paulínia to the capital Brasília, is one of these engineering works that deserves to be pointed out. This research, performed at the Ribeirão da Prata Basin, was a pilot study conducted with the main objective of testing the current methodology efficiency, for future applications in the closest watersheds to the OSBRA pipeline. The objective of this research is to analyze flood wave and debris flow processes in a non-fictional watershed, by comparing two different kinds of methods: the first one based on simulation models (software ‘ABC 6’), and the other one by flood wave and debris flow susceptibility mapping. The results from the hydrological modeling were both hydrographs and ietographs that estimated values of outputs and infiltration. To construct the susceptibility maps were necessary three other maps: ground use and occupation maps, divided according to the different protection degrees that were offered to the ground; maps of dam locations in the area and physiographic compartimentation maps, divided according to the local geology. To complete the methodology, the results were collected from both methods for comparison. The obtained product for this methodology was series of data whose different susceptibility degrees to flood wave and debris flow could define the safest route for a pipeline crossing in this watershed...

Elaboração de mapa de susceptibilidade de corridas de massa/detritos e ondas de cheia, aplicado a empreendimentos dutoviários, na bacia hidrográfica do Ribeirão da Prata (SP)

Given the intense expansion of the industries in Brazil and the discovery of hydrocarbons in the pre-salt layer of the Santos and Campos Basin, there is a need to expand the distribution of oil and gas network in the country. The present work aims to present the development of susceptibility map by two distinct methods of two events (debris flows and full wave), applied to the establishment of pipelines on Ribeirão da Prata Basin. The research area covers two municipalities: São João da Boa Vista and Águas da Prata, in total 145 km2. In the paper was used the methodology proposed by Zaine (2011) for the physiographic subdivision method, which uses geological maps, geomorphological maps, digital terrain models and aerial photographs, used to extract the main elements of the physical environment, as rivers, lines, ridges, tops forms and valley forms and historical processes. Thus, the basin was divided into 11 physiographic zones, considering the following elements: thickness of soil, rock type, geomorphology, amplitude, ridges orientation, erosion occurences and mass movements. Were subsequently performed location maps of dams, that had as main purpose to localize major dams in the study area along with their area and perimeter of the reservoir, and land use map that subdivided the area in woody vegetation, permanent culture, temporary culture and urban area. Along with the preparation of the auxiliar maps was conducted a field campaign with three days and approximately 2 points per km2, which aimed to better understand the physical environment and check the main peculiarities of the study area. Criteria have been established for susceptibility maps physiographic subdivision and land use, and a survey of criteria weights used in each map for both processes under study. For the preparation of susceptibility maps were adopted two different methods, which treat the weighted average and the multiplicand. The weighted average method it is...

Análises de solos e sedimentos de corrente, nas áreas das usinas de fundição de chumbo do Calabouço (CIEM-CPRM) e de beneficiamento de minério aurífero do Morro do Ouro (Parque Municipal Morro do Ouro), no município de Apiaí - SP

Located in Apiaí, Vale do Ribeira, southern region of São Paulo state, the Usina do Calabouço areas (CIEM / CPRM) and Morro do Ouro (Parque Municipal do Morro do Ouro), were targeted for stud ies due to its old buildings, respectively a foundry in lead ore, called Experimental de Chumbo e Prata (Usina Calabouço), and a gold mine with processing plant of the gold-bearing ore produced there. Nowadays, the areas are used for public visitation, and in both places the rests of the buildings remains. Particularly in the CIEM/CPRM, due to the materials witch was produced before, it can suggest the existence of anomalous amounts of the involved metals (CIEM / CPRM) and possible contaminations by chemical products used in the improvement of the auriferous ore (P. M. Morro do Ouro). These potential contamination were confirmed with geochemical survey of soils and current sediments accomplished in both areas, for the elements arsenic, cadmium, lead, copper, mercury, silver and zinc, which were used as parameters guiding values for soil and groundwater the state of São Paulo (CETESB), and watershed values stipulated by CPRM (poor, background and anomalous), in it rising geochemistry during Folha Apiaí's execution (SG-22-X-B-V).

Estudo da distribuição e das densidades larvais do bivalve invasor Limnoperna fortunei (Dunker, 1857) nos principais corpos d’água da bacia do rio da Prata

O mexilhão-dourado (Limnoperna fortunei) é um bivalve de água doce pertencente à família Mytilidae. Originário de rios e arroios da China e do sudeste asiático, foi introduzido acidentalmente na América do Sul em 1991, no estuário do rio da Prata, provavelmente através de água de lastro. Como encontrou condições propícias para o seu desenvolvimento, se expandiu através dos rios Uruguai, Paraná e Paraguai, sendo atualmente o principal responsável pelo macrofouling em ecossistemas de água doce do continente. O presente estudo compreende uma área de grande extensão na bacia do Rio da Prata, onde foram amostrados pontos estratégicos nos rios Paraná (e seus principais afluentes), Uruguai e Paraguai. A partir de coletas de organismos do plâncton, realizadas por arrasto vertical, foram quantificadas as densidades de larvas de L. fortunei em cada local de amostragem. Assim, obteve-se um panorama atual da ocorrência do mexilhão, registrando-se, inclusive, alguns limites de sua distribuição. As densidades mostraram-se, no geral, elevadas, provavelmente em decorrência do período de amostragem (verão 2010), onde a atividade reprodutiva da espécie é maior devido às altas temperaturas. Porém, grandes variações ao longo da bacia foram registradas, o que pode estar relacionado ao grau de antropização, disponibilidade de substratos, velocidade da corrente, tempo de introdução, entre outras variáveis

Morfoanatomia de folha e escapo de Abolboda (Xyridaceae - Poales)

Os representantes de Xyridaceae estão agrupados em duas subfamílias: Xyridoideae, que compreende o gênero Xyris e Abolbodoideae, que compreende os gêneros Abolboda, Achlyphila, Aratitiyopea e Orectanthe. Como as relações entre as espécies de Xyridaceae e delas com outras Poales não estão bem estabelecidas, o trabalho teve como objetivo a caracterização morfológica e anatômica de folhas e escapos de táxons brasileiros de Abolboda buscando levantar estruturas que os diferenciassem e que servissem de comparação com os demais gêneros. Foram estudadas: Abolboda poarchon var. poarchon, A. poarchon var. intermedia, A. pulchella e A. macrostachya. As características morfológicas como comprimento e largura de folhas, comprimento de escapos e de bainhas dos nós dos escapos e número de feixes vasculares no mesofilo são importantes para diferenciar os táxons entre si. Folhas e escapos com epiderme unisseriada, estômatos localizados pouco acima do nível das demais células epidérmicas, presença de hipoderme, parênquima paliçádico e lacunoso e feixes vasculares colaterais; folhas com estômatos paracíticos somente na face abaxial e margem com colênquima logo abaixo da epiderme, caracterizam anatomicamente os táxons de Abolboda estudados. As espécies de Abolboda apresentam algumas características anatômicas contrastantes com Xyris e outras similares com os demais gêneros, corroborando a divisão da família em duas subfamílias. A presença de nó nos escapos de Abolboda é um caráter diagnóstico do gênero. Abolboda macrostachya apresenta características anatômicas exclusivas da espécie. A. poarchon e A. pulchella apresentam muitas características anatômicas semelhantes e ocorrem simpatricamente.

Bioatividade de cipó-prata (Trigonia nivea Cambess) sobre a excreção renal de água e eletrólitos e pressão arterial

Brazil is a country with the largest world´s vegetal genetic diversity and the Environmental Protection Area (APA) of the “Serra da Mantiqueira” is a very heterogeneous region, representing one of the richest sources of pharmacologically actives materials. The population uses medicinal plants and according to the OMS, 80% of the population uses them in primary treatment of several diseases. Nevertheless, the loss of traditional knowledge associated with medicinal plants is occurring quickly. The ethnopharmacological strategy uses traditional knowledge to the search for medicinal plants that can have bioactive substances against diseases that afflicting the population and thus protect traditional knowledge. The “cipó-prata” (Trigonia nívea Cambess.) is a native plant normally found in the “Bacia do Paraná” region and present in the flora in the neighborhood of “Marins”, Piquete-SP and usually, said for the treatment of renal and urinary diseases. So, the objective of this study was test if the “cipóprata” (Trigonia nívea Cambess.) has effects on the renal excretion of water and salt, in anesthetized Wister rats. The tests were made in males Wistar rats and randomly distributed into 4 experimental groups: Group I – aqueous control, Group II – treated with aqueous extract (EA) of “cipó-prata”, Group III – water control + “tween 80”, Group IV – treated with ethanol extract (EE) and “cipó-prata”. All groups were subjected to experimental protocol, composed of three periods: Balance (40 minutes), Basal (30 minutes) and Experimental (90 minutes), occurring the urine collection every 30 minutes, from the basal period and measuring blood pressure every 10 minutes. The aqueous extract (EA) of “cipó-prata” (Trigonia nívea Cambess.) presented diuretic effect of 173% (B-2,4±1,19 μL/min reaching 6,6±1,45 μL/min, in the period EX3) and ...(Complete abstract click electronic access below)

Clonagem e caracterização do promotor de um gene com expressão em folha de Eucalipto (Eucalyptus grandis)

Uma das principais estratégias de ação da biotecnologia na área vegetal trata da produção de plantas geneticamente modificadas com transgenes de interesse. Entretanto, para garantir a correta expressão de tais transgenes em plantas de interesse agronômico e florestal, como é o caso do eucalipto, a identificação e caracterização de seqüências promotoras com padrões conhecidos de expressão gênica se fazem necessárias. Nesse contexto, o presente trabalho objetivou clonar e sequenciar a região promotora de um gene com expressão em folha de Eucalyptus grandis. Em seguida, um cassete de expressão contendo o gene repórter GUS sobre controle do referido promotor foi construído e introduzido em vetor binário. O referido cassete foi então inserido em agrobactéria visando a futura transformação de plantas modelo para a realização de estudos funcionais

Preparação e caracterização da casca de banana prata particulada para aplicação com reforço em compósito de matriz de PEAD

The waste, exaggerated and incorrect disposal of biomass are common practices in modern times where everything is disposable. However the growing concern with the nature and the environment compel man to give nobler destinations for these products through sustainability and recycling of waste. Banana peel is a residual biomass, which is not consumed. It generates tons of waste per week in São Paulo city. This trash is disposed in dumps and landfills, which could be reduced by using it as reinforcement in natural composites. The high density polyethylene (HDPE) is a polymer derived from the ethylene polymerization and is easily recycled. Which makes it a sustainable material. In the present work characteristics of the natural composite composed with banana peel and high-density polyethylene were studied. It was noted that removing the lignin present in the banana peel, the fiber introduces a significant improvement in thermal resistance. The preparation of composite was made with a ratio of 5% and 10% of reinforcement in comparison with polymeric matrix mass. Composites were thermally, mechanically and microscopically characterized. The addition of fiber in the polymer increased the mechanical strength of the composite. The fiber surface treatment with distilled water removed the amorphous material present in the fibers, improving significantly thermal stability and increasing crystallinity of the celullose. The addition of 5% fiber in mass to the polymer increased significantly the tensile strength and elasticity modulus for the composite. With 10% of fiber addiction there were also an improvement when compared with pure HDPE, but when compared with 5% composite the mechanical properties are slightly lower. This may be due to the fiber particle size, which are small and eventually become a hub of tension ... (Complete abstract click electronic access below)

O pequi no noticiário: análise dos resultados de uma pesquisa na busca do site Folha de S. Paulo

Among the fruit species of the Brazilian Cerrado, the pequi is much popular in regions where it is extracted. Often it used in typical dishes, on the industry medicinal, cosmetic and handmade, also it studied its potential to produce fuel. Thus, this article sought to ponder about the disclosure of this fruit in the press, by means of the search system's site Folha de S. Paulo and applying content analysis, proposed by Bardin, beyond bibliography and documentary research. The justification for this research is that the pequi is a fruit of great importance in the economy and sustainable, yet little is spoken about it in the mainstream media. The result is that, by the analysis, little is said about the pequi media and its focus, is principally, cultural journalism, in culinary.
