13. Study of Polychaeta associations in Santos Bay and Adjacent Continental Shelf (SP, Brazil) and their interrelations with physical and geochemical patterns / Estudo das associações de anelídeos Polychaeta da Baía de Santos e Plataforma Continental Adjacente (SP, Brasil) e suas interrelações com parâmetros físicos e geoquímicos estruturadores
The aim of the present work was to verify the spacial and vertical Polychaeta distribution in sediment samples of Santos Bay and adjacent continental shelf by analyzing physicochemical characteristics, granulometric pattern, chemical compounds concentration and metallic elements. Parallely, it looked for determining the organic matter origin by C/N/S content

14. Parâmetros de resistência do solo para dimensionamento de sistemas de drenagem em estradas não pavimentadas / Parameters of soil resistance for drainage systems dimensioning in non-paved roads
This work was developed mainly aiming the determination of the erodibility and the critical shear stress in non-paved roads, focusing on the reduction of the eminent risks of occurring erosion in these roads, based upon a drainage system dimensioning using local resistance values. In order to achieve these values a yield simulator was built, which model cons

15. Análise da influência da geoquímica do ambiente e das características do substrato na estruturação da população de Corbicula flumínea, MULLER 1974, (Mollusca, Bivalvia) no reservatório da usina elétrica de Volta Grande - MG/SP
Corbicula fluminea (Müller, 1774) is a very common fresh water bivalve specie in Asiatic continent. Nowadays can be found widespread distributed in Europe, North and South America. Considering their high reprodutive rate and spreading capacity of their juvenile plancton forms, this bivalve could be considered as a highly invading specie, being a dominant co

16. IMPLEMENTATION OF THE GEOTECHNIC ENGINEERING EXPERIMENTAL FIELD OF UFSM / IMPLANTAÇÃO DO CAMPO EXPERIMENTAL DE ENGENHARIA GEOTÉCNICA DA UFSM
Presently, on the Geotechnic Engineering art, the superficial and deep foundation projects are conditioned for the load capacity and for the admissibles settlements. The foundation projects and geotechnic sites in Santa Maria/RS have a preponderant empirical character. The soil knowledge are based, almost exclusively, on their behavior on previous sites and

17. Moluscos dos substratos inconsolidados do mediolitoral do estuÃrio do Rio JaboatÃo, Pernambuco - Brasil
Estuaries are high productivity ecosystems and very important to consumers of different throphic levels. In general, estuaries are under strong anthropogenic influence affecting the residents species. The JaboatÃo River is very important to the city of same name and also to other cities including Recife, as many families are dependent upon the fisheries, in

18. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w

19. VariaÃÃo temporal da meiofauna e da nematofauna em uma Ãrea mediolitorÃnea da bacia do Pina (Pernambuco, Brasil)
The basin of Pina has been studied for many years in order to check the level of organic pollutants. Many rivers are discharged in this basin bringing a big amount of pollutants to it. This affects the quality of organisms fished by the poor population that lives in the neighborhood. Up to now thereâs only one studie on meiofauna, specifically on nematofaun

20. Microbiological and Physical Properties of Salt Marsh and Microecosystem Sediments †
Sediments from natural marsh and four microecosystem (MES) tanks were compared with reference to ATP, carbon content, and physical properties. Mean values for bacterial numbers and ATP were about twice as high in the MES, carbon content was slightly higher in the artificial systems, and the sediment of the MES was enriched for larger grain sizes and depleted
