1. Reflection of attenuated waves at the surface of a fractured porous solid saturated with two immiscible viscous fluids
The mathematical model for wave motion in a fractured porous solid is solved for the propagation of harmonic plane wave along a general direction in 3-D space. The solution is obtained in the form of Christoffel equations, which are solved further to define the complex velocities and polarisations of five attenuated wavesin the medium. Four of these waves ar

2. Determinação de elementos químicos inorgânicos em amostras de sangue total humano e de animais de experimentação (hamster dourado e cavalo da raça crioula) pela técnica de fluorescência de raios X(EDXRF) / Inorganic elements determination in human and animal whole blood samples by X-ray fluorescence technique (EDXRF)
Blood is a suspension of cells contained in a complex liquid called plasma. The term whole blood refers to samples with both solid and liquid parts. Inorganic elements are responsible for essential functions, such as osmotic regulation, cardiac frequency and contractibility, blood clotting and neuromuscular excitability. The determination of inorganic elemen

3. APLICAÇÃO DE MÉTODOS VOLTAMÉTRICOS DE ANÁLISE NA ESPECIAÇÃO DE CROMO, SELÊNIO E ANTIMÔNIO EM MATRIZES SALINAS / APPLICATION OF VOLTAMMETRIC METHODS TO THE SPECIATION ANALYSIS OF CHROMIUM, SELENIUM AND ANTIMONY IN SALINE MATRICES
This work aimed to explore the speciation analysis of chromium, selenium and antimony, elements of clinical and geochemical relevance, in the saline samples seawater, hydrothermal fluid and hemodialysis fluid. These samples, although linked to different research areas, have many similarities relating to their chemical compositions or the presence of metallic

6. Caracterização eletroquímica de colóides magnéticos visando a aplicações nanotecnológicas nanobiotecnológicas
Electric Double Layered Magnetic Fluids (EDL-MF) are stable colloidal dispersions of spinel ferrite type nanoparticles in water medium. The thermodynamic stability is achieved by balancing the van der Waals and magnetic dipolar attractions with the introduction of repulsive electrostatic interactions between particles in order to avoid the agglomeration phen

7. Geologia e petrologia do prospecto GT-34 : evidência de metassomatismo de alta temperatura e baixa fO2, província mineral Carajás, Brasil
The GT-34 Prospect in the Carajás Mineral Province is located within older gneissmigmatite terrains (Xingu Complex). Sulfide mineralization is hosted by irregular bodies of brecciated rocks and/or orthopyroxene-amphibole bearing rocks outcropping among gneissic rocks. Distribution of sulfide-rich intervals form an irregular NE trend of about 1.5 km-long and

8. Mathematical modeling and numerical simulation of incompressible flows over complexes three-dimensional geometries using the immersed boundary method / Modelagem matemática e simulação numérica de escoamentos incompressíveis sobre geometrias complexas tridimensionais utilizando o método da fronteira imersa
The necessity of understand the physical mechanisms in flows over complexes geometries are something imperative on modern engineering. In this way, tools that allow the analysis and understanding of such flows are very important as well. In this work, a numerical tool that allows the transient analysis of flows over several types of complexes three-dimension

12. Experiments on the fundamental mechanisms of boiling heat transfer
The lecture presents a survey of results found by the author and his team during recent years. An experimental technique for precise and systematic measurements of entire boiling curves under steady-state and transient conditions has been developed. Pool boiling experiments for well wettingfluids and fluids with a larger contact angle (FC-72, isopropanol, wa
