1. Contribution to the forecast of horizontal displacements in continuous fight auger piles in granular soil profile
Abstract This article presents a series of propositions for the prediction of horizontal displacements for continuous fight auger piles in granular soil profiles through modifying the parameters Ay and By from the method proposed by Matlock and Reese (1961). Empirical proposals were also presented for calculating the horizontal soil reaction coefficient (nh)

2. Thermostimulated crystal structure transformation of the polymineral clay submicron particles
Abstract Changes in the structure of phyllosilicate microparticles of submicron fractions of polymineral clay with an average size of 290 nm, as well as changes in the positions of impurity ions of transition metals in the crystal lattice, were studied by X-ray diffraction analysis, Fourier transform infrared spectroscopy, and high-resolution electron parama

3. FILM NARRATIVES CROSSING TIME AND SPACE IN THE AMERICAS: A COMPARATIVE PERSPECTIVE OF LA JAULA DE ORO (2013) AND EL NORTE (1983); RIO (2011) AND THE THREE CABALLEROS (1944)
Abstract The essay discusses how frequent migratory currents of certain narratives and ideas within the Americas have formed clusters of knowledge and stimulated audiences’ imagination about specific cultures or nations. The essay presents the process of narrative continuity and displacement in recent films about immigration and travel within the Americas,

4. Numerical formulation for nonlinear analysis of concrete and steel shells with deformable connections
Abstract A two-dimensional interface finite element capable of associating flat shell elements positioned one above the other was developed. The implemented interface element can physically simulate the contact between the flat shell elements and connect the reference planes of the shell elements above and below it. The formulation presented allows considera

5. Settlement of bored piles with expander body system in lateritic soils
Abstract The Expander Body pile (EB) is a combination of a cast-in-situ pile method with an inflated, pump-grouted tip. The EB system's pioneering conjunction with the conventional drilling pile technique has improved work load, foundation security, cost reductions and abrupt displacements in lateritic, porous, unsaturated soils. The aim of this article is t

6. PARAMETERS FOR MODELING PASSIVE SUSPENSIONS OF SPRAY BARS
ABSTRACT The uniformity and quality of spraying depend on the stability of the spray boom, defined as the suspension system between the boom and the machine chassis. This paper presents a procedure for improving the performance of passive spray bar suspensions through parameter adjustment. Two multibody dynamics models of a tractor sprayer set were developed

7. Optimization of geometrically nonlinear truss structures under dynamic loading
Abstract The goal of this article is to present the formulation of the optimization problem of truss structures with geometric nonlinearity under dynamic loads and provide examples of this problem. The formulated optimization problem aims to determine the cross-sectional area of the bars that minimizes the weight of the structure, imposing constraints on nod

8. 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

11. MIGRAÇÃO E MOBILIDADE PENDULAR NAS ÁREAS DE INFLUÊNCIA DE METRÓPOLES BRASILEIRAS
RESUMO Em vários momentos no tempo a mobilidade populacional serviu como fonte motora de profundas transformações sociais e econômicas nas regiões de origem e destino no Brasil, não sendo apenas consequência das necessidades estruturais. Além dos tradicionais fluxos migratórios, a mobilidade pendular também tem assumido papel relevante no processo
