3. Estudo dos Parâmetros de União por Difusão do Aço Inoxidável AISI 316L
Resumo A união por difusão é uma técnica de união no estado sólido capaz de ligar dois materiais metálicos por meio da difusão atômica na interface de contato, sem o uso de metal de adição. Este processo é adequado para a união de grandes áreas com uma alta resistência mecânica, permitindo ao equipamento operar com elevadas pressões de traba

6. Effect of diode laser irradiation on the bond strength of polymerized non-simplified adhesive systems after 12 months of water storage
Abstract Objectives: The aim of this in vitro study was to evaluate the bonding strength of non-simplified dentin bonding systems (DBS) to dentin irradiated with a diode laser (970 nm) immediately and after 12 months of water storage following either primer or bond application. Material and methods: The experimental design included three different factors:

7. An interface element for numerical analysis of flat plate/shell elements with deformable connection
Abstract The use of numerical methods such as the finite elements method for solving structural analysis problems is becoming ever more efficient. An interface element capable of associating flat plate/shell element in three different combinations has been developed. In a structural analysis, when only the flat plate/shell’s finite elements are used in th

8. Development of a computational instrument using a lagrangian particle method for physics teaching in the areas of fluid dynamics and transport phenomena
Abstract Particle methods are an alternative to the traditional mesh Eulerian methods for solution of fluid dynamics and transport phenomena problems. The Lagrangian Meshless Smoothed Particle Hydrodynamics (SPH) method presents advantages compared to mesh methods as a better visualisation of the spatio-temporal evolution of the flow (and the fluid propertie

9. Assessment of Digital Elevation Model for Digital Soil Mapping in a Watershed with Gently Undulating Topography
ABSTRACT Terrain attributes (TAs) derived from digital elevation models (DEMs) are frequently used in digital soil mapping (DSM) as auxiliary covariates in the construction of prediction models. The DEMs and information extracted from it may be limited with regard to the spatial resolution and error magnitude, and can differ in the behavior of terrain featur

10. An in vitro assessment of type, position and incidence of isthmus in human permanent molars
Root canal anatomical complexities, such as isthmus, may limit the action of the endodontic instruments, irrigant solutions and intracanal medications, leading to endodontic treatment failure. Objectives: This in vitro study assessed the type, position and incidence of isthmus in human permanent molars. Material and Methods: One hundred and twenty eight u

11. Expressão das proteínas citoesqueléticas actina e tubulina em células osteogênicas cultivadas sobre vidro e vitrocerâmica bioativos / Expression of the cytoskeletal proteins actin and tubulin in osteogenic cells cultured on bioactive glass-based surfaces
Bioactive glasses and glass-ceramics have been successfully applied in various therapeutic strategies to promote the formation of mineralized matrix in bone defects. The exposure of these materials to biological fluids results in chemical and topographical modifications that may affect the interactions of cells with the biomaterial surface, with potential ef

12. Biologia populacional do poliqueta exogone (exogone) breviantennata Hartmann-Schröder, 1959 (Syllidae: Exogoninae) / Population biology of the polychaete exogone (exogone) breviantennata Hartmann-Schröder, 1959 (Syllidae: Exogoninae)
The study of the syllid Exogone (Exogone) breviantennata was conducted in two soft bottom beds of the mytilid Mytella charruana at Camaroeiro and Cidade beaches, located on the northern coast of São Paulo. To characterize the study areas, samples were taken monthly between february 2006 and february 2007 at Camaroeiro, and between april 2006 and april 2007
