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. 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

3. Numerical analysis of reinforced concrete asymmetric cross-section beams under oblique bending
Abstract The problem of symmetric cross-section beams under oblique bending is well known to professional designers and academy. In fact, symmetric elements make up most of the cross-sections defined in design. The case of the asymmetric cross-sections is, however, little discussed in literature, but is a particular problem, especially in bridge girder desig

4. Dynamic response of a 120 mm smoothbore tank barrel during horizontal and inclined firing positions
AbstractIn this study, the dynamic interaction between a 120 mm smoothbore tank barrel modeled as an Euler-Bernoulli cantilever beam and an accelerating projectile during firing is presented. The interaction was modelled using a new FEM approach that took into account the projectile's inertia, Coriolis, and centripetal forces and the horizontal and inclined

5. Biomechanical evaluation of subcrestal dental implants with different bone anchorages
This study evaluated the biomechanical influence of apical bone anchorage on a single subcrestal dental implant using three-dimensional finite element analysis (FEA). Four different bone anchorage designs were simulated on a posterior maxillary segment using one implant with platform switching and internal Morse taper connection as follows: 2 mm subcrestal p

6. A FEM-BEM interactive coupling for modeling the piezoelectric health monitoring systems
In this research, finite element and boundary element methods are coupled together to model the interaction of a piezoelectric ceramic working as an actuator with an elastic material. Piezoelectric-elastic material's interaction occurs in smart structures. This work is aimed at determining the actuation effects being transferred from the actuators to the hos

7. Verificação da aplicabilidade de tecnologia GNSS para o monitoramento de deslocamentos horizontais em barragens de concreto / Verification of the applicability of GNSS technology for monitoring the horizontal displacements of concrete dams
A segurança dos empreendimentos civis tem se tornado fator preponderante na viabilidade econômica das obras, uma vez que impacta o preço dos seguros cobrados. Dentro deste contexto, um dos aspectos importantes a serem considerados na elaboração de um projeto, notadamente no de grandes estruturas, é a instrumentação. Assim, ao se tratar com grandes ba

8. The Jitter Spatial Frequency Sweep VEP: a new paradigm to study spatiotemporal development of pattern- and motion-processing mechanisms in human infants
We introduce a new VEP paradigm - the Jitter Spatial Frequency (JSF) Sweep VEP - that permits efficient mapping of the spatiotemporal tuning of the developmental motion asymmetry (DMA). Vertical sinewave gratings undergoing 90º horizontal oscillatory displacements (6 or 10 Hz) were presented while their SF was swept over 2 to 5 octaves during each VEP trial

9. Manutenção da postura ereta em condições de perturbação: influência da execução de uma tarefa manual simultânea e incerteza sobre a direção da perturbação / Maintenance of upright stance in conditions of perturbation: influence of simultaneous manual task executation and uncertainty of perturbation direction
This study aimed to investigate the reactive components of postural adjustments in response to displacements of the basis of support, disturbing body balance, as a function of a concomitant manual execution of a supra-postural task and uncertainty about the perturbation direction. Sixteen young adults of both genders (M = 26,3 years; SD = 2,6) participated i

10. Análise do comportamento de estacas strauss submetidas a carregamento horizontal no solo da região de Londrina - PR
In Londrina city, Strauss piles are frequently used as retaining structure for building basement excavation, being submitted to horizontal load. However, the projects of such retaining structures are usually conducted using design methods that do not take the concrete cracking of pile transversal section and the properties of lateritic tropical soil into acc

11. Contribution to the study of the influence of excavations on the superficial settlements of nearby constructions / Contribuição ao estudo da influência de escavações nos recalques superficiais de construções vizinhas
The present thesis aims at contributing to the study of the influence of excavations on settlements of nearby structures. This is a theme of major interest in urban areas where a concentration of tall buildings is very common. A detailed analysis of the main available empirical methods is presented dealing with the settlement prediction caused by nearby exca

12. ModificaÃÃes topogrÃficas da junÃÃo uretrovesical da uretra proximal apÃs cirurgia combinada de Marshall-Marchetti-Krantz e Burch no tratamento da incontinÃncia urinÃria de esforÃo: avaliaÃÃo ultra-sonogrÃfica
Urethrovesical junction hypermobility is responsible for approximately 95% of stress urinary incontinence cases. Transvulvar sonography has been largely used to assess urethrovesical junction and proximal urethra mobility. Colposuspension surgeries most widely performed for the treatment of stress urinary incontienence are Burch and Marshall-Marchetti-Krantz
