2. A casa físsil: o corpo migrante e os paradoxos da hospitalidade na poesia de Eduardo Jorge
Resumo Se a casa é o centro geográfico a partir do qual os caminhos se abrem e a cidade se oferece, frequentemente a vivência do migrante altera a percepção desse “chez soi” e enfraquece sua oposição aos espaços públicos, abertos, compartilhados. A hospitalidade pode tornar-se hostilidade. O presente artigo busca examinar os abalos na representa

3. SOFT-TISSUE INJURY TO THE FOOT AND ANKLE: LITERATURE REVIEW AND STAGED MANAGEMENT PROTOCOL
RESUMO O trauma complexo do pé e tornozelo, caracterizado por fraturas com dano grave aos tecidos moles, associado a lesões vasculares e nervosas e com acometimento articular, está presente com frequência no paciente politraumatizado e é preditor de desfecho clínico desfavorável. Na abordagem inicial de um paciente com trauma complexo do pé e tornoze

4. NÃO DEIXAM DE SUSPIRAR PELA SUA LIBERDADE: MOTINS DE ÍNDIOS NO CEARÁ E A FORMAÇÃO DO ESTADO NO BRASIL
RESUMO A atuação dos índios inseridos na formação do Estado brasileiro era, muitas vezes, caracterizada pelos administradores como “tumultos”. Nesse clima de instabilidades, era assustador para as elites políticas das diversas regiões do Brasil o fato de novas ideias estarem sendo apropriadas pelas camadas subalternas. Indo além dos atos de nomea

5. Isokinetic performance of ankle evertor and invertor muscles in adolescent female volleyball athletes
Abstract Aims: This study aimed to analyze the muscular performance of evertor and invertor ankle muscles of adolescent volleyball athletes. Methods: The information provided by database concerning the isokinetic evaluation of ankle muscles from 20 female volleyball players between the ages of 14-17 years old were analyzed. The isokinetic dynamometer was

6. Direct Numerical Simulation of a Compressible Flow and Matrix-Free Analysis of its Instabilities over an Open Cavity
ABSTRACT: This study takes a Jacobian-free approach based on the Arnoldi iteration to present a method to perform hydrodynamic instability analysis based on Direct Numerical Simulations. The method employs high order spatial and temporal discretizations for the flow simulation and has very low requirements of computational time and memory, compared to conven

7. Transition from Thermokinetic to Chemical Instabilities in a Modified Sal’nikov Model
Traditionally, thermokinetic and chemical oscillations have been studied independently, but in cellular media recent studies have shown that cell’s temperature is not uniform. Thus, on this context it is possible to inquire about the influence of thermal effects on chemical oscillatory behavior and vice versa. To this end, in this paper we propose a dynami

8. Relevance of Dynamic Strain Aging under Quasi-Static Tension on AISI 304 Stainless Steel
The interval of existence of dynamic strain aging (DSA) in AISI type 304 austenitic stainless steel subjected to quasi-static tension tests, under strain rates from 3.5 x 10-2 to 3.5 x 10-4 s-1, in the temperature range from 25 to 800ºC was investigated. It was found that DSA occurs in the range extending from around 200 to 700ºC. Plastic instabilities ass

9. Precipitation Evolution and Modeling of Growth Kinetics of L12-structured Al3Zr Particles in Al-0.22Zr and Al-0.32Zr (wt.%) Alloys Isothermally Aged
The microstructure and microhardness of isothermally aged Al-0.22Zr and Al-0.32Zr alloys were investigated. Peak microhardness occurred after aging at 650K for 100 h for both alloys and decreased slightly after aging at 400 h. Nanometer-scale spherical L12-structured Al3Zr precipitates were observed using Transmission Electron Microscopy, these presented r <

10. Combined Cycle Performance Evaluation and Dynamic Response Simulation
ABSTRACT Power plants operating in combined cycle present higher thermal efficiency (over 60%) and increased power generation when compared to traditional simple cycles, such as gas or steam turbines operating alone. Considering that the power plant evaluated in this paper is already operational, a further development concerning to the power plant control sy

11. Structural Topology Optimization Based on the Smoothed Finite Element Method
Abstract In this paper, the smoothed finite element method, incorporated with the level set method, is employed to carry out the topology optimization of continuum structures. The structural compliance is minimized subject to a constraint on the weight of material used. The cell-based smoothed finite element method is employed to improve the accuracy and sta

12. APPLICATION OF A SURFACE-RENEWAL MODEL TO PERMEATE-FLUX DATA FOR CONSTANTPRESSURE CROSS-FLOW MICROFILTRATION WITH DEAN VORTICES
AbstractThe introduction of flow instabilities into a microfiltration process can dramatically change several elements such as the surface-renewal rate, permeate flux, specific cake resistance, and cake buildup on the membrane in a positive way. A recently developed surface-renewal model for constant-pressure, cross-flow microfiltration (Hasan et al., 2013)
