1. THE EVOLUTION OF ENVIRONMENTAL GOVERNANCE MECHANISMS: AN INSTITUTIONAL FRAMEWORK APPLIED TO BIOFUELS
Resumo Esse artigo apresente uma ferramenta analítica para avaliar a evolução de mecanismos de governança ambiental. A trajetória institucional dos mecanismos de certificação é influenciada por três variáveis pré-existentes: regulação pública, organização e competição setorial e mecanismos de legitimação. A competição entre sistemas de

2. Computing Cartel Overcharges: when theory meets practice
Resumo O sucesso na aplicação da lei de defesa da concorrência no que diz respeito à punição de cartéis depende de procedimentos sólidos de investigação e punição eficaz. No entanto, a legislação existente apenas fornece direção para o cálculo das multas de cartel com base na receita de vendas, ainda que tais multas não possam ser inferiore

3. Severe Loading Assessment of Modern and New Proposed Beam to Column Connections
AbstractThe performance of two different steel beam to column connections known as SidePlateTM and a new proposed connection by seismic loading and progressive collapse were investigated in this research. Seismic performance evaluated included consideration of interstory drift angles and flexural strengths based on 2010 AISC Seismic Provisions while investig

4. Parametric Model Method and Deployment Simulation of Inflatable Antenna Structures
ABSTRACT: In this paper, we develop a parametric model method and simulate the deployment mechanism of inflatable antenna structures. Different folded methods are developed for the primary members of inflatable antenna structures, which include inflatable tubes, an inflatable torus, a reflector etc. The unstressed configuration and the folded configuration o

5. 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

6. Use of serological techniques for determination of Spodoptera frugiperda(J E Smith) predators (Lepidoptera: Noctuidae)
Spodoptera frugiperda (J E Smith) is an important pest of several crops, but especially on maize in Brazil. The implementation of biological control measures hinges on the identification of its predators and other natural enemies. As a means of identifying predators, antibodies against S. frugiperda eggs were generated by inoculating rabbits with macerated S

7. Análise da deformação pós-Rifte na Bacia do Araripe, Nordeste do Brasil
The Araripe Basin is located over Precambrian terrains of the Borborema Province, being part of Northeast Brazil inner basins. Its origin is related to the fragmentation of the Gondwana supercontinent and consequently opening of South Atlantic during early Cretaceous. The basin has a sedimentary infill encompassing four distinct evolution stages, comprising

8. Crime and punishment with habit formation
Moral concepts affect crime supply. This idea is modelled assuming that illegal activities is habit forming. We introduce habits in a intertemporal general equilibrium framework to illegal activities and compare its outcomes with a model without habit formation. The findings are that habit and crime presents a non linear relationship that hinges upon the lev

9. Diagnóstico numérico de vigas Vierendeel formadas por perfis tubulares metálicos de seção circular / Numerical diagnosis of Vierendeel trusses made in steel circular hollow structural sections
Vierendeel trusses are framed structures having parallel chord members used in several types of buildings where lighting, ventilation and architectural definitions do not permit using cells with diagonal web members as in classic trusses. This work presents a study of Vierendeel trusses formed by hollow structural sections considering the global structure be

11. Formulation of a lumped dissipation model for nonlinear analysis of reinforced concrete planed frame structures / Formulação de um modelo de dissipação concentrada para a análise não-linear de estruturas reticuladas planas em concreto armado
O trabalho trata da formulação, implementação e aplicação de um modelo para análise não-linear de estruturas reticuladas planas em concreto armado, baseado no conceito simplificado de localização dos processos físicos irreversíveis (dano, plasticidade e histerese) em zonas previamente definidas denominadas rótulas que se localizam nas extremidad

12. Aplicação do método da otimização topológica para o projeto de mecanismos flexíveis menos suscetíveis à ocorrência de dobradiças. / Topology optimization to design hinge-free compliant mechanisms.
Os mecanismos flexíveis são dispositivos capazes de transmitir força e movimento através da deformação elástica. Têm grande importância a uma série de aplicações nas quais os mecanismos de corpos rígidos não seriam viáveis, como por exemplo, os sistemas microeletromecânicos. Existem várias maneiras pelas quais os mecanismos flexíveis podem
