1. Rapid diagnosis of respiratory distress syndrome by oral aspirate in premature newborns,
Resumo Objetivo: O teste das microbolhas estáveis no aspirado gástrico e no líquido amniótico foi usado no diagnóstico da síndrome do desconforto respiratório do recém-nascido. Contudo, nenhum estudo fez esse teste nos aspirados bucais de neonatos prematuros. O objetivo deste estudo foi avaliar o desempenho do teste das microbolhas estáveis em aspi

3. Aqueous Nanofluids Based on Copper MPA: Synthesis and Characterization
The application and use of efficient cooling fluids have become increasingly important due to the increasing industrial and energy demand associated with the miniaturization of various electronic devices. The search for high-efficiency heat exchanger fluids in the early 1990s led to the development of a new class of refrigerants called nanofluids. The use of

4. Interaction between thermoregulation and osmoregulation in domestic animals
ABSTRACT The ability to maintain core temperature as well as volume and composition of body fluids within narrow ranges is a major characteristic of mammals. Yet, the ability to maintain a stable core temperature often relies on physiological responses that perturb the stability of body fluids. A common thermoregulatory mechanism that affects body fluid home

5. AVALIAÇÃO DO POTENCIAL USO DE BIOGLICERINA COMO BASE PARA FORMULAÇÃO DE FLUIDOS DE PERFURAÇÃO AQUOSOS PARA POÇOS DE PETRÓLEO E GÁS
The growing global concern about the environment associated with academic and government efforts are enabling a number of alternatives for sustainable development. Within this perspective one can include the search for value-added products using waste from renewable energy sources, such as those from the production of biodiesel. The rapid development of biod

6. microRNAs and the mammary gland: a new understanding of gene expression
MicroRNAs (miRNAs) have been identified in cells as well as in exosomes in biological fluids such as milk. In mammary gland, most of the miRNAs studied have functions related to immunity and show alterations in their pattern of expression during lactation. In mastitis, the inflammatory response caused by Streptococcus uberis alters the expression of miRNAs t

7. DESENVOLVIMENTO DE UM PROCESSO CONTÍNUO PARA PRODUÇÃO DE BIODIESEL A BAIXAS TEMPERATURAS. / DEVELOPMENT OF A CONTINUOUS PROCESS FOR PRODUCING BIODIESEL AT LOW TEMPERATURES.
Biodiesel has emerged worldwide as a promising alternative to oil-derived mineral fuels. It is biodegradable, renewable, obey to the carbon cycle and can be defined as fatty acid monoalquyl esters derived from renewable sources, such as vegetable oils and animal fats. It can be produced from a transesterification reaction, in which there is the transformatio

8. A numerical investigation of inertia flows of Bingham-Papanastasiou fluids by an extra stress-pressure-velocity galerkin least-squares method
This article is concerned with finite element approximations for yield stress fluid flows through a sudden planar expansion. The mechanical model is composed by mass and momentum balance equations, coupled with the Bingham viscoplastic model regularized by Papanastasiou (1987) equation. A multi-field Galerkin least-squares method in terms of stress, velocity

9. Evolução magmática, alteração hidrotermal e gênese da mineralização de ouro e cobre do Palito, Província Aurífera do Tapajós (PA) / Magmatic evolution, hydrothermal alteration and geneseis of gold-copper mineralization at Palito, Tapajós Gold Province (PA)
The Palito porphyry type copper-gold deposit is located in the central region of the Amazonian craton, in the Tapajós Gold Province (TGP), in an area that is dominated by intermediate to felsic granitic and volcanic rocks of late Paleoproterozoic age. Three lithotypes make up this deposit. The Palito Granite, with porphyritic features, is the host rock for

10. Mecânica de suspensões magnéticas diluídas
This work concerns with an investigation of the dynamics of dilute suspensions composed by magnetic particles, considering microstructural and macroscopic aspects of this particulate systems. From the microstructure, it is known that magnetostatic attraction may lead to formation of aggregates in magnetic suspensions. In this way, numerical simulations have

11. 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

12. Simulation of multiphase fluid into digital images / Simulação de fluido multifásico em imagens digitais
In the last years, fluid simulation has been one of the main focus in Computer Graphics. Such a reason is related to applications to film industry, games and frameworks for realtime physical problem simulations. In this work we aim at accessing a problem which is not so much explored in Computer Graphics: fluid simulation in digital images. We adopt a approa
