1. Application of computational fluid dynamics on a study in swine facilities with mechanical ventilation system
ABSTRACT: Ventilation systems used in swine facilities deserve to be studied because they directly affect productivity in the pig farming sector. Bearing this in mind the uniformity of air distribution and temperature is essential to animal welfare in this breeding environment. Thus, the purpose of this study was to identify whether changes in air entrances

2. On Micro-Buckling of Unidirectional Fiber-Reinforced Composites by Means of Computational Micromechanics
Abstract Micro-buckling of unidirectional fiber-reinforced composites is investigated in this paper by means of an explicit representation of a geometrically imperfect fiber within the context of kinematical and material non-linear behavior. Two types of fiber imperfections are considered: a helicoidal shape, identified as 3D imperfection; and a sinusoidal p

3. Hydrolytic and Thermal Degradation of PCL and PCL/Bentonite Compounds
Poly(Ɛ-caprolactone)/montmorillonite (PCL/MMT) and Poly(Ɛ-caprolactone)/organo-modified montmorillonite (PCL/OMMT) compounds at 3% w/w clay content were prepared by melting mixing. The effect of MMT and OMMT on the degradability of PCL injected specimens was investigated in vacuum at 40oC for up to 45 days and in aqueous medium at 40oC for up to 45 days. S

4. TMJ response to mandibular advancement surgery: an overview of risk factors
Objective: In order to understand the conflicting information on temporomandibular joint (TMJ) pathophysiologic responses after mandibular advancement surgery, an overview of the literature was proposed with a focus on certain risk factors. Methods: A literature search was carried out in the Cochrane, PubMed, Scopus and Web of Science databases in the

5. Orthopedic treatment of Class III malocclusion with rapid maxillary expansion combined with a face mask: a cephalometric assessment of craniofacial growth patterns
OBJECTIVE: The aim of this prospective study was to assess potential changes in the cephalometric craniofacial growth pattern of 17 children presenting Angle Class III malocclusion treated with a Haas-type expander combined with a face mask. METHODS: Lateral cephalometric radiographs were taken at beginning (T1) and immediately after removal of the appliance

6. As ligações semirrígidas na análise avançada com zona plástica de portais planos de aço
In this work, the development of the Plastic-Zones Advanced Analysis of plane steel portals is studied, now including the connections effect. Firstly, this analysis is defined as inelastic second-order which capture the plasticity spread by slice technique and includes the Main Aspects as geometric (out-of-straight and out-of-plumb) and physical imperfection

7. Um modelo geometricamente exato de barras com grandes deformações, que considera a distorção e o empenamento geral da seção transversal, e sua discretização pelo método dos elementos finitos. / A fully nonlinear geometrically exact multi-parameter rod model that incorporates general in-plane and out-of-plane cross-sectional changes, and its discretization by Finite Element Method.
The main purpose of this work is to present a fully nonlinear geometrically-exact multi-parameter rod model that incorporates general in-plane cross-sectional changes as well as general out-of-plane cross-sectional warping. The formulation constitutes an extension of the earlier works presented in [1] to [6], [8] and [9], in the sense that the restrictions t

8. Sedimentary facies and provenance of the Bebedouro Formation, Neoproterozoic (BA) / Fácies sedimentares e proveniência da Formação Bebedouro, Neoproterozóico (BA)
The sedimentary record of Neoproterozoic age has become a major subject of research since the rebirth of the models of extreme glaciation and rapid climatic changes for the period, including the Snowball Earth hypothesis. These models are founded on the identification, in all continents, of Neoproterozoic diamictites directly overlain by carbonates, which ar

9. SUBSÍDIOS PARA O PLANEJAMENTO DO BALNEÁRIO DO MAR GROSSO, SÃO JOSÉ DO NORTE, RS: AVALIAÇÃO DE ASPECTOS GEOMORFOLÓGICOS E MORFODINÂMICOS COM AUXÍLIO DE GEOTECNOLOGIAS.
The oceanic coast of the Rio Grande do Sul is divided in three sectors: northern, central and southern. The city of São José do Norte, which is part of the central coast, has a small beach-resort with reduced urbanization called Mar Grosso Beach. Major negative environmental impacts on this beach are represented by foredunes occupation, urbanization and ga

10. Efeitos de tensão em filmes finos de manganitas estudados por espectroscopia de absorção de raios-X com luz linearmente polarizada
Among the materials exhibiting the Colossal Magnetoresistance e effect, mixed manganite thin films have received special attention due to their potential applications for new generation magneto-eletronic devices. In these systems, the external biaxial strain could be used to tune the magnetism and transport properties if it were possible to settle the exact

11. The effect of iron displacement out of the porphyrin plane on the resonance Raman spectra of heme proteins and iron porphyrins.
The causes of the strong coupling of the iron-histidine vibration to the Soret resonance in the resonance Raman spectra of deoxyhemoglobin, myoglobin, and peroxidase are explored, using the vibronic theory. It is shown that the extent of the iron displacement out of the plane of the porphyrin nitrogens is the main structural parameter controlling the Fe-NHis

12. Fourier transform infrared difference spectroscopy of bacteriorhodopsin and its photoproducts.
Fourier transform infrared difference spectroscopy has been used to obtain the vibrational modes in the chromophore and apoprotein that change in intensity or position between light-adapted bacteriorhodopsin and the K and M intermediates in its photocycle and between dark-adapted and light-adapted bacteriorhodopsin. Our infrared measurements provide independ
