1. The interaction of a naturally occurring membranous collagen with high-saline dye solutions – mechanistic features from unusual multi-step biosorption
ABSTRACT It is known that wastewaters containing dyes are very difficult to treat, since many dyes are stable and recalcitrant molecules. In this way, sorption may suitable for effectively remove dyes in this specific application field. In this work, a first approach for using polymeric membranous collagen of fish scales for sorption of saline methylene blue

2. Characterization and Chemical Stability of Hydrophilic and Hydrophobic Magnetic Nanoparticles
Magnetic nanoparticles can improve the efficiency of phase separation time in multi-stage operations when a magnetic field is present. As such operations involve contact with aqueous and/or organic solutions, hydrophilic magnetic nanoparticles synthesized through the co-precipitation method were functionalized with oleic acid to attain hydrophobic magnetic n

3. Non-parametric stability analyses of dough properties in wheat
AbstractLiterature has unveiled that a paper has not been published yet on using non-parametric stability statistics (NPSSs) for evaluating genotypic stability in dough properties of wheat. Accordingly, the effects of genotype (G), environment (E) and GE interaction (GEI) on alveograph parameters, i.e. dough baking strength (W) and its tenacity (P)/extensibi

4. 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

5. Atenção para tarefas simples e complexas nas perspectivas de primeira e terceira pessoa : um experimento fenomenológico / Attention to simple and complex tasks in the perspectives of first and third person: a phenomenological experiment
Compara-se o desempenho atentivo entre tarefas moleculares (foco em tarefas simples e reduzidas), para as quais o sentido é uma atribuição externa, com tarefas molares (foco em tarefas complexas que requerem apreensão abstrata e global), para as quais o sentido é uma atribuição interna. A pesquisa foi organizada em três estudos. No primeiro, exibiu-s

6. Magneto-tunelamento ressonante em super-redes de GaAs/AsGaAs
In this thesis we present three works in weakly coupled semiconductor superlattices of GaAs/AlGaAs. In the first work we present an investigation of the electric field domain configuration in the sequential tunneling regime in weakly coupled superlattices in the presence of a magnetic field applied parallel to the quantum well layers. We show that, for an ap

7. Hydrothermal alteration of the Cerro La Mina gold prospect, Los Menucos, Patagonia Argentina : geology, remote sensing and stable isotopes / Alteração hidrotermal do prospecto aurifero Cerro La Mina, Los Menucos, Patagonia Argentina : geologia , sensoriamento remoto e isotopos estaveis
The epithermal Cerro La Mina prospect, located in the Los Menucos region, Patagonia Argentina, is currently being explored for epithermal precious-metal mineralization. Triassic hydrothermal activity produced intense alteration of rhyolites, andesites, ignimbrites, and tuffs of the Middle- to Late Triassic Los Menucos Group, in the Somún Curá massif. The u

8. STUDY OF SCATTERING OF ULTRASOUND WAVES BY DEFECTIVE INTERFACES / ESTUDO DO ESPALHAMENTO DE ONDAS ULTRA-SONICAS POR INTERFACES DEFEITUOSAS EM JUNTAS COLADAS
It is well known that the global strength of multi-layered composite structures strongly depends on the quality of the adhesion between its constituent elements. Imperfections along interfaces of adhesion can strongly compromise structure s performance. The characterization of such defects is a very difficult task. The main goal of this study is the developm

9. Robust predictive control of a gasoline debutanizer column
This paper studies the application of Model Predictive Control to moderately nonlinear processes. The system used in this work is an industrial gasoline debutanizer column. The paper presents two new formulations of MPC: MMPC (Multi-Model Predictive Controller) and RSMPC (Robust Stable MPC). The approach is based on the concepts of Linear Matrix Inequalities
