13. CONSTRUCTION AND TESTING OF GLUED LAMINATED TIMBER FRAMES FOR USE IN LAYING POULTRY HOUSES
ABSTRACT This study aimed to present a solution in glued laminated timber to replace frame structures built in reinforced concrete and metallic structure, which are common in agricultural buildings in western Paraná such as those destined to laying poultry house building by agricultural cooperatives. Structural behavior of frames build from Araucaria angust

14. ESTIMATION OF WOOD TOUGHNESS IN BRAZILIAN TROPICAL TREE SPECIES
ABSTRACT Wood has been used for several purposes such as in civil and rural construction. Knowing wood mechanical behavior under short-term loading is essential for safer structural designs. However, wood toughness is a mechanical property little investigated for this purpose. Thus, this study aimed to evaluate, using exponential and polynomial regression mo

15. Composite floor system with CFS trussed beams, concrete slab and innovative shear connectors
Abstract Steel and concrete floor systems are widely applied for buildings and provide excellent structural response, optimized material consumption, reduced beam height, and improved bending strength and stiffness capacity. In recent years, many experimental investigations concerned with new alternatives addressed to efficient interaction between steel and

16. PMMA-SiO2 Organic-Inorganic Hybrid Coating Application to Ti-6Al-4V Alloy Prepared through the Sol-Gel Method
Siloxane-poly(methyl methacrylate) (PMMA) hybrid was synthesized based on the sol-gel method and applied to Ti-6Al-4V through dip-coating. The structural feature of the hybrid was subjected to Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG); its morphological properties were analyzed through scanning electron microscope (SE

17. Multistage Phase Decomposition Behavior and Kinetics for Zr65Ni30Pd5 Ternary Amorphous Alloy
We have examined heating-induced phase decomposition and its kinetics for Zr65Ni30Pd5 amorphous alloy in an argon atmosphere. The amorphous phase decomposes through three stages in the order of amorphous → icosahedral quasicrystal (I-Q) + amorphous → approximant cubic Zr2(Ni,Pd) → tetragonal Zr2Ni + tetragonal Zr2Pd phases. The approximant crystalline

18. Escuela Media, Trabajo Joven, y hegemonía en la Argentina neodesarrollista: una mirada estructural
Abstract The following article presents a series of findings that arise from statistical analysis of enrollment data originated in Argentina’s Secondary Education system, which is then linked to youth employment indicators for the same period. Those are interpreted making use of theoretical approaches provided by critical currents of Sociology of Education

19. SPECTROSCOPIC CHARACTERIZATION OF PEDOT:PSS CONDUCTING POLYMER BY RESONANCE RAMAN AND SERRS SPECTROSCOPIES
Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) synthesis was monitored by resonance Raman (RR) and surface-enhanced resonance Raman scattering (SERRS) spectroscopies and both the oxidation of the polymer and the effects of chain length were assessed by vibrational analysis. It was supported by theoretical models of oligomers, with charge

20. Personalidade e Comparecimento Eleitoral na América Latina: Efeitos de Características Psicológicas Individuais em Contextos de Obrigatoriedade
RESUMO Estudos sobre comparecimento eleitoral têm se dedicado à identificação dos condicionantes desse comportamento focalizando fatores de natureza estrutural, como o nível de desenvolvimento econômico das nações e características do sistema político, enquanto outros destacam variáveis individuais, como atributos sociodemográficos e atitudinais.

21. Numerical implementation of a micromechanics-based viscoelastic model for geomaterials with isotropically distributed micro-fractures
Abstract The constitutive behavior of geomaterials is generally affected by the presence at different scales of discontinuity surfaces with different sizes and orientations. According to their mechanical behavior, such discontinuities can be distinguished as cracks or fractures. Fractures are interfaces that can transfer normal and tangential stresses, where

22. Curiosity as Brazilian tourist motivation in visiting Europe
Resumo Embora o tema das motivações push and pull tenha recebido consideração crescente na literatura de comportamento turístico, pouca atenção tem sido dedicada à investigação da interação entre motivações de impulso único, fidelidade dos turistas e outras variáveis relevantes que influenciam seus comportamentos. Dada a sua relevância inque

23. Estudo experimental do fluxo de umidade em argamassas de cal aérea
RESUMO Uma parte significativa do património histórico construído ao redor do mundo é constituída de alvenaria estrutural, com juntas preenchidas com argamassa. Nesses sistemas estruturais, a argamassa usualmente representa uma parcela pequena/moderada do volume total da estrutura, no entanto, a argamassa é reconhecida como a principal fonte de movimen
