1. Effects of soil-structure interaction in seismic analysis of buildings with multiple pressurized tuned liquid column dampers
Abstract In this paper soil-structure interaction (SSI) effects are investigated while an array of Pressurized Tuned Liquid Column Dampers (PTLCD) is employed for seismic vibration control of buildings. This device represents the most general case of a passive damper, with different reduction options to other control devices obtained by simplifying the invol

2. A injunção social da maternagem e a violência
Resumo: Nos últimos séculos a mulher experimentou diversas conquistas relacionadas à sua forma de ser e estar no mundo, se adaptando às conjunturas sociais, econômicas, intelectuais e políticas. Com essa ocupação espacial da mulher, a liberdade de agir e de se expressar ficou mais latente, desobrigando-a dos comportamentos sociais compulsórios. Entr

3. Princípio do prazer como regulador de uma civilização em declínio
Resumo: Neste artigo, recusa-se o frequente pessimismo de Freud, tantas vezes denunciado por seus leitores, em relação à vida dos homens e aos destinos da humanidade, recusa auxiliada pela distinção, em sua obra, entre o domínio da metapsicologia e o da clínica. O primeiro domínio, fortemente associado à sistematização da psicanálise, admite um d

4. A short remark on the modelling of a three-story shear-building structure
Abstract In this note, some remarks on the modelling of a multi-degree-of-freedom system, a three-story shear-building structure, is presented. The modelling of a mechanical system is one of the most important aspects in engineering and physics, since is crucial for the understanding of the system. Besides, the model, if properly made, can be also useful to

5. Stress-Based Finite Element Methods for Dynamics Analysis of Euler-Bernoulli Beams with Various Boundary Conditions
Abstract In this research, two stress-based finite element methods including the curvature-based finite element method (CFE) and the curvature-derivative-based finite element method (CDFE) are developed for dynamics analysis of Euler-Bernoulli beams with different boundary conditions. In CFE, the curvature distribution of the Euler-Bernoulli beams is approxi

6. Cultivando las plantas y la sociedad waorani
Abstract Agricultural practices produce information that reveals the relationship between people and the environment. This study describes and analyzes the agricultural itinerary of the Waorani people of the Ecuadorian Amazon, through which major sociocultural characteristics are materialized: individual freedom and personal autonomy. During fifteen months o

7. Campbell Diagrams of a Spinning Composite Shaft with Curvilinear Fibers
Abstract This paper presents the vibratory behavior of a spinning composite shaft with curvilinear fibers on rigid bearings in the case of free vibrations. A p-version of finite element is used to define the model. A theoretical study allows the establishment of the kinetic energy and the strain energy of the shaft, necessary to the result of the equations o

8. Finite Element Modelling for Static and Free Vibration Response of Functionally Graded Beam
Abstract A 1D Finite Element model for static response and free vibration analysis of functionally graded material (FGM) beam is presented in this work. The FE model is based on efficient zig-zag theory (ZIGT) with two noded beam element having four degrees of freedom at each node. Linear interpolation is used for the axial displacement and cubic hermite int

9. Analysis of the flexural mode response of a novel trimaran by segmented model test
A novel ship concept design is significantly an "adhoc" process. In the preliminary design stage of novel vessels, it is very important to be able to develop an initial estimate of the effects of stiffness and mass distribution on the longitudinal flexural natural frequencies due to different general arrangements in still water at zero speed to satisfy desig

10. Dynamic analysis of a spinning functionally graded material shaft by the p - version of the finite element method
This paper is concerned with the dynamic behavior of the spinning Functionally Graded Material (FGM) shaft on rigid bearings. A p- version, hierarchical finite element is employed to define the model. A theoretical study allows the establishment of the kinetic energy and the strain energy of the shaft, necessary to the result of the equations of motion. In t

11. Active vibration control of a piezoelectric beam using PID controller: Experimental study
Vibration suppression of smart beams using the piezoelectric patch structure is presented in the present work. The smart system consists of a beam as the host structure and piezoceramic patches as the actuation and sensing elements. An experimental set-up has been developed to obtain the active vibration suppression of smart beam. The set-up consists of a sm

12. A Teoria da assunção do risco e a prática esportiva, análise à luz do direito civil-constitucional. / The theory assumption of risk and the sporting activity in acordance with the civil constitucional law.
O presente trabalho analisa a teoria da assunção do risco, que se originou no Direito francês com influência do commow Law, aplicável na atividade desportiva à luz dos princípios e valores do Direito Civil-Constitucional. O risco é estudado a partir dos conceitos de liberdade e dignidade, demonstrando que a liberdade não é absoluta, limitada pela d
