1. A Experiência no Mundo Existencial, Segundo Dewey
Resumo: Este estudo bibliográfico tem por objetivo explicitar a compreensão de Dewey sobre a existência enquanto instância natural onde ocorrem as experiências dos organismos ali encontrados em situação de transação permanente. A existência natural é o mundo da fragilidade, imprevisibilidade, contingências, devido ao conflito de forças opostas,

2. Inelastic second-order analysis of steel columns under minor-axis bending
Abstract The inelastic second-order behavior of steel structural columns under minor-axis bending is presented in this article. To study this behavior, a nonlinear frame element formulation is adopted in which the steel's plasticity process is accompanied at the nodal points of each finite element through the refined plastic-hinge method (RPHM). A tangent mo

3. Comparison of deflection forces of esthetic archwires combined with ceramic brackets
Abstract Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coated nickel-titanium (NiTi) and esthetic archwires combi

4. 3D finite element modeling of grains refinement for magnesium alloys by extrusion-shear and experimental verification
To explore the deformation mechanisms of a new composite extrusion including extrusion and successive shear subsequently which is shorten "ES", Three dimensional finite element modeling of grain refinements for magnesium alloys by ES process has been researched. The ES die have been designed and manufactured and installed to the horizontal extruder. Finite e

5. Nietzsche e a crítica ao historicismo: uma análise a partir da relação entre história e vida na segunda consideração intempestiva.
The present work has for purpose analyze through a interpretative reading, the critical of the Nietzsche to the historicism starting from the relationship between history and life. The historicism is understood in this dissertation as the exaggerating use of the historical knowledge, the faith in a philosophy of the history as it presented the Hegelianism an

6. Efeito do ângulo da fieira na geometria e propriedades mecânicas de barras trefiladas
In cold drawing of metallic bars most of the plastic flow is caused by compressive forces which arise from the reaction of the metal to the die. Due to the characteristics of the process this flow is not homogeneous along the cross section of the bar and is influenced by the die geometry. This inhomogeneous deformation generates residual stresses in the bars

7. Description of consolidation forces on nanometric powders
The experiments and analyses performed included measurements of the physical properties of TiO2 powder such as the particle size, density, and consolidation. Experiments with nanometric TiO2powder of 204 nm average diameter show that, during consolidation, the adhesion of particles under normal stress is principally due to the van der Waals force for particl

8. Estudo dos esforços de corte no processo HSM aplicado à abertura de cavidades / Study of the cutting forces in HSM process applied to pocket milling
The manufacturing of a great number of components in the industry depends on molds and dies used in processes like forging, powder metallurgy, deep drawing, casting and plastic injection. One of the main operations for manufacturing of these parts corresponds to the opening of the initial pocket, from which more complex geometries are machined in order to ob

9. Tecendo o estético e o sensível através do bordado na literatura infantil brasileira / Weaving the aesthetic and sensitive through the embroidery on Brazilian childrens literature
Childrens literature brings two different concerns: the story told by the verbal text, and the one brought by the images of the book cover and of the book. The visual text can awake the senses by an aesthetic experience while what is written on the book can take the reader to a comprehension of the world and of the cultural and moral values. The learning is

10. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

11. Processamento de aço inoxidável dúplex por extrusão em canal angular
A duplex stainless steel with austeniticferritic structure, type S32205/S31803 was submitted to equal channel angular pressing, whose is based on very severe plastic deformation, at relatively low temperature, with no change in the dimensions along transversal section of the material. The processed material was heat treated at 1000 and 1200C during 7.5, 15,

12. Análises tensão-deformação de estruturas de solo grampeado. / Stress-Strain analysis of soil nailed structures.
The limit equilibrium methods that are frequently used for design of soi nailing structures do not provide information about the structures stress and strain. However, the techniques success depends on the displacements that mobilize the nails strength. Therefore it is desirable to predict the structures displacement, during and after the excavation; the for
