Levantamento e monitoramento da malacofauna de água doce da região de influência direta do Sistema Produtor do Alto Tietê (SPAT) / Survey and monitoring of the freshwater malacofauna in the region of direct influence of the Alto Tietê System Producer (SPAT)Silva, Jucimara Christina Freire da 21 October 2010 (has links)
O aumento dos impactos ambientais devido à construção de reservatórios e barragens leva ao aumento dos riscos da infecção humana por agentes infecciosos causadores de endemias em especial as transmitidas por espécies dos moluscos de água doce, notadamente os riscos da esquistossomose mansônica. A literatura relata a distribuição geográfica de Biomphalaria tenagophila, Biomphalaria glabrata e Biomphalaria straminea presentes nas coleções hídricas de São Paulo, mostrando que uma das maiores concentrações de criadouros da espécie encontram-se no terço inicial da Bacia do Rio Tietê. No presente estudo, realizado na Represa Paraitinga (município de Salesópolis) situada na região de influência direta do Sistema Produtor do Alto Tietê (SPAT) no ano de 2009, no período de março a dezembro, foram coletados 386 moluscos, representados por 4 famílias, 1 gênero e 4 espécies, sendo 338 Biomphalaria tenagophila, 23 Lymnaea columella, 17 Physa marmorata, 7 Ampullarie sp. e 1 Drepanotrema cimex. Nenhum exemplar de B. tenagophila capturado mostrou-se positivo para Schistosoma mansoni, porém foram encontrados espécimes de B. tenagophila infestados por larvas de trematódeos identificados como Cercaria caratinguensis. As relações de determinantes ambientais analisadas foram: turbidez, cor, pH e oxigênio dissolvido. A utilização de um GPS (Global Positioning System) possibilitou a localização precisa dos locais de coleta / The increase of environmental impacts due to construction of reservoirs and dams leads to an increase in human exposure to infectious agents, that cause endemic diseases in particular those transmitted by species of freshwater snails, especially schistosomiasis mansoni. Literature shows the geographic distribution of Biomphalaria tenagophila, Biomphalaria glabrata and Biomphalaria straminea present in water collections in São Paulo, it also shows that one of the largest concentrations of breeding sites of those species are in the initial part of the Tietê Basin. The present work was carried out in Paraitinga dam (Salesópolis municipality) located in the region of direct influence of the Alto Tietê System Producer (SPAT). In 2009, from march to december, 386 specimens were collected, representing 4 families, 1 genus and 4 species, where 338 were Biomphalaria tenagophila, 23 Lymnaea columella, 17 Physa marmorata, 7 Ampullarie sp. and 1 Drepanotrema cimex. None of the captured B. tenagophila specimen was positive for Schistosoma mansoni, but some of them were infested with larval trematodes, which were identified as Cercaria caratinguensis. The relations of environmental factors examined were: turbidity, color, pH and dissolved oxygen. The use of a GPS (Global Positioning System) enabled the precise localization of the collecting site

Aspectos do enchimento da represa Paraitinga, sistema produtor Alto Tietê: zooplâncton e qualidade da água / Aspects of the filling of Paraitinga Reservoir, Sistema Produtor Alto Tietê: zooplankton and water qualityNascimento, Vanessa Cristina 20 October 2008 (has links)
Devido ao rápido crescimento demográfico, a construção de represas tornou-se indispensável para suprir a demanda de água necessária para abastecer toda a população e o sistema econômico e social que a mantém. A transformação de um rio em um lago artificial não promove apenas efeitos positivos; essa prática altera permanentemente o ambiente no qual ela é inserida, com conseqüências prejudiciais e irreversíveis. O objetivo deste estudo foi acompanhar o processo de enchimento da represa Paraitinga, que faz parte do Sistema Produtor Alto Tietê (SPAT) e está associada ao abastecimento de água da Região Metropolitana de São Paulo, através de alterações nas características físicas e químicas da água, além de alterações na estrutura e composição da comunidade zooplanctônica. O processo de enchimento não se deu de forma homogênea e o seu recrudescimento foi acompanhado por aumentos mais acentuados na profundidade do reservatório. Foi verificado que esta represa, apesar de recém-formada, já apresenta alguns sinais de comprometimento da qualidade da água, tais como valores elevados de condutividade elétrica. Não ocorreu depleção de oxigênio nas camadas próximas ao fundo, apesar de muitos autores relatarem que é comum os reservatórios apresentarem condições de anoxia nas camadas mais profundas da coluna dágua durante o período de enchimento. A estrutura da comunidade esteve instável durante todo o período de estudo, sendo observada uma alternância da dominância dos grupos que a compuseram; apesar disso, houve predominância marcante de rotíferos. Foi verificado que o processo de enchimento não acarretou efeito de diluição sobre as variáveis físicas e químicas, mas que as alterações na velocidade com que se dava este processo influenciaram as flutuações de densidade numérica apresentadas pelo zooplâncton. / Due to rapid population growth, construction of dams has become indispensable to meet the demand of water needed to supply the entire population and to support the social and economic system. The transformation of a river in an artificial lake not only promotes positive effects, the practice changes permanently the environment in which it is inserted, with harmful and irreversible consequences. This study aimed to follow the filling process of Paraitinga Reservoir, which is part of the Sistema Produtor Alto Tietê (SPAT) and is linked to the water supply of Metropolitan Region of Sao Paulo, through changes in physical and chemical characteristics of the water, as well as changes in the structure and composition of the zooplankton community. The process of filling has not been so homogeneous and its rise was accompanied by high increases of the reservoir depth. It was found that this dam, though newly formed, is already showing some signs of impairment of water quality, such as high values of electrical conductivity. There was no depletion of oxygen in layers near the bottom, although many authors reported that during the filling, many of the reservoirs showed anoxic conditions of the deeper layers of water column. The zooplankton community structure was unstable throughout the studied period, and it was observed an alternation of the dominance of the groups. Nevertheless, there was marked predominance of rotifers. It was found that the process of filling had not caused a dilution effect on the physical and chemical variables, but that changes in the velocity of the process has influenced fluctuations of the numerical density of the zooplankton.

Relative Habitat Value Of Alternative Substrates Used In Oyster Reef RestorationGeorge, Lindsey Marie 16 December 2013 (has links)
Oyster reef habitats have declined from historic levels due to a variety of reasons, including overharvest, disease, and degraded water quality. The harvesting of oysters has led to a loss of reef habitat for both oysters and reef-associated fauna. When oysters spawn, the larval oysters, or spat, depend on hard substrate for settlement and growth. Oyster shell is the preferred substrate for use in restoration because it most closely matches natural reef habitat, but it is often expensive and in limited supply. This study incorporated field and laboratory experiments to assess the relative habitat value of alternative substrates (crushed concrete, porcelain, crushed limestone, and river rock, as well as oyster shell) for larval oyster recruitment as well as reef resident fishes and macro-invertebrates. Replicate trays of each substrate type were deployed in St. Charles Bay, TX for four months during spring and summer 2012 and assessed for oyster recruitment and faunal diversity and density. Concrete, river rock, limestone and porcelain had similar spat recruitment densities compared to oyster shell (1300-2300 spat). Spat shell heights were also larger on these substrates (13-16 mm), while spat on porcelain substrates were slightly smaller (10-13 mm). All substrates except bare sediment had similar fauna species densities (200-500 individuals m-2). Limestone had lower fauna diversity (H’; 0-1) than concrete and shell (1-2). Laboratory experiments compared the effectiveness of these substrates in providing prey refuge from pinfish and blue crab predators. All substrates performed similarly resulting in very low (<20 %) prey mortality rates for either predator. Results may enable future restoration plans to be implemented at a lower cost while providing similar habitat functions.

Emulace infrastrukturní jednotky pro systém inteligentní dopravy / Emulation of infrastructure unit for inteligent transport systemGiertl, Juraj January 2018 (has links)
The thesis deals with the study of communication models for cooperative intelligent transport systems and the development of the application used for testing. The ETSI ITS-G5 and IEEE 1609.x DSRC/WAVE comunication stacks were compared to standartizes layered ISO/OSI reference model. The basic principes of comunication in inteligent transport systems are described for each model. Besides that the common messages structures for defining alert messages, the intersection geometry and trafic lights signals are described in further detail. Based on these structures and other requirements, an application is created that allows easy definition of alert messages, intersection geometry and its traffic light states.

Die Pferde aus dem sächsischen Gräberfeld Rullstorf (Ldkr. Lüneburg): eine anatomisch-paläopathologische Untersuchung und ein Vergleich mit rezenten PferdepopulationenBecker, Ilona 29 May 2019 (has links)
Gangmechanische Grundüberlegungen und skelettpathologische Erscheinungen, wie sie in
der heutigen Pferdezucht bekannt sind, werden in die Bewertung der Reste von 42 Pferdeskeletten des sächsischen
Gräberfeldes von Rullstorf bei Lüneburg einbezogen. Neben den üblichen Fragestellungen nach Alter, Geschlecht
und Widerristhöhe wird erörtert, an welchen Knochenproportionen sich überhaupt Laufeigenschaften
festmachen lassen. Dazu werden neben anderen frühmittelalterlichen auch rezente Populationen zu Vergleichen
herangezogen, um eine nutzungstypologische Einordnung zu erzielen.
Gelenkveränderungen der Rullstorfer Pferde werden in ihrer Ätiologie betrachtet und mit den Problemen an Gelenken heutiger Pferde verglichen. Nicht nur die reine Darstellung der Ausgrabungspferde ist ein Anliegen dieser Arbeit. Die Erkenntnisse aus den Knochenresten von Individuen längst vergangener Zeiten können auch bei der Aufklärung von Problemen heutiger Tiere einen Beitrag leisten. / Mechanics of movement and pathological signs of the skeleton, well-known in modern horsebreeding,
influence the evaluation of 42 horse-skeletons of a saxon burial ground (Rullstorf near Lüneburg,
Germany). Beside usual questions concerning the age, sex and wither height it is explored which proportions of bone-lenght are responsible for the character of movement at all. Horse-populations of the early Middle Ages and modern races are used for comparisons to look for the type of use.
Joint changes of the Rullstorf horses are described within their etiology and compared with problems of modern horses. Not only the pure description of the excavation-horses is wanted for this paper. Rests of bones which belong to individuals of historical times can help to clear up the problems of our today-living animals.
