1. Reinforcement of Polyester with Renewable Ramie Fibers
Ramie (Boehmeria nivea) fiber is one of several lignocellulosic fibers with superior strength, but the least investigated, particularly as reinforcement in strong, tough polymeric composites. This paper presents mechanical properties for polyester reinforced with aligned ramie fibers up to 30% by volume. It was found that adding 30 vol% of ramie fibers incre

2. Task and delay of reinforcement effects on mathematical questions solution behavior among children with or without ADHD / Efeitos de atraso e tarefa na resolução de problemas matemáticos em crianças com e sem TDAH
The Attention Deficit Hiperativity Disorder (ADHD) has been related to self-control. In behavior analysis, self-control/impulsivity situations have been studied using alternatives differing in reinforcer delay and magnitude. Studies with ADHD children have shown that they have a stronger preference for immediate reinforcers, in comparison to children without

3. Consequências Arbitrárias: Análise de Diferentes Magnitudes em Cadeias de Respostas Públicas e Privadas.
This study examined experientially behaviors considered mental processes by other psychological guidelines, but for Behavior Analysis, founded by the philosophy of Radical Behaviorism proposed by Skinner, are considered private verbal behaviors, as thought. To verify functional relations that artificial contingencies perform on participants performance and t

4. Análise crítica dos critérios normativos de dimensionamento à punção em lajes lisas
The Brazilian code NBR 6118/2003 introduces significant changes in the criteria for the punching shear strength of reinforced and prestressed concrete flat slabs. In this scenario, the objective of this work is to evaluate these punching shear design procedures in terms of safety, precision and economy with respect to test results of reinforced and prestress

5. Algumas relações do comportamento cooperativo com as variáveis custo de resposta e magnitude do reforço / Some relations between cooperative behaviour relationships and the variables response-cost and magnitude of reinforcement
Este estudo foi desenvolvido com o objetivo de investigar algumas relações do comportamento cooperativo, manipulando-se reforços de maior magnitude para tarefa cooperativa do que para a tarefa individual, e aumento gradativo da razão para obtenção de reforços na alternativa cooperativa. Quatro participantes, de ambos os sexos, com faixa etária varian

6. Self-control: a study on the effect of simultaneous variation of reinforcer magnitude and delay and the possibility of engaging in a distracting activity / Autocontrole: um estudo sobre o efeito da variação simultânea da magnitude e do atraso do reforço e da possibilidade de realização de atividades distrativas
The present study was aimed at analyzing child self-control through the simultaneous variation of magnitude and delay of reinforcement, with and without the possibility of engaging in a distracting activity during the delay of reinforcement. The participants, 11 children between the ages of five to eleven, with and without a diagnosis of ADHD, were presented

7. COMPORTAMENTO DE UMA ESCAVAÇÃO GRAMPEADA EM SOLO RESIDUAL DE GNAISSE / BEHAVIOUR OF A NAILED EXCAVATION IN GNEISSIC RESIDUAL SOIL
The behavior of a nailed excavation in gneissic residual soil has been studied by a comprehensive research program, including instrumentation, field and laboratory tests and numerical analyses. Soil nailing is becoming a popular stabilization technique in Brazil. However, a solid knowledge about the soil-nail interaction is still lacking. There are a few stu

8. COMPARAÇÃO DE MÉTODOS DE PROJETO PARA MUROS DE SOLO REFORÇADO COM GEOSSINTÉTICOS / COMPARISON OF DESIGN METHODS FOR GEOSYNTHETICS REINFORCED SOIL WALL
Atualmente, muitos projetistas utilizam diferentes métodos para o projeto de muros de solo reforçado com geossintéticos. Uma avaliação desses diversos métodos pode ser realizada pela comparação com os resultados obtidos do monitoramento de casos reais e suas respectivas retro- análises, sendo este o objetivo desse trabalho. Na presente pesquisa, tr�

9. Comportamento de escolha: um estudo sobre efeito da variação simultânea da magnitude e do atraso do reforço a partir da replicação sistemática de Ferreira (2002) / Choice Behavior: a study on the effect of simultaneous variation of reinforcer magnitude and delay through a systematic replication of Ferreira (2002)
The present experiment is a systematic replication of Ferreira (2002) and aimed to analyze the choice behavior in typical developing children through the simultaneous variation of reinforcer magnitude and delay. The participants, 6 five to six year-old children who studied at a public state pre-school, were exposed to a computer choice task programmed in con

10. Sensitivity of children to variations in reinforcer amount and delay, using toy to reinforcer / Sensibilidade de crianças à variações na magnitude e atraso do reforçamento, usando brinquedo como reforço
The present study investigated if children s choice in a concurrent chained schedule could be controlled by variations on reinforcement delay or magnitude. Six children, ages between 5 and 6 years old, were submitted to a chained VI-VI 15s schedule on the initial ink of the chain. Children responded on a computer screen using a mouse. On the terminal link, r

11. O que se diz e o que se faz: um estudo sobre interações entre comportamento verbal e comportamento não verbal
O presente estudo investigou a ocorrência de interações entre comportamento verbal e não verbal em esquemas múltiplos. Seis adolescentes e uma criança participaram de três experimentas. Nestes experimentas, os sujeitos foram submetidos a um jogo de computador, durante o qual períodos para emissão de respostas não verbais (pressão a uma tecla manti

12. Condicionamento operante e manutenção da resposta de bicar o disco em esquemas de reforçamento continuo por pombos (Columba livia) submetidos a ablação das estruturas telencefalicas
This work analysed in two experiments the learning and the retention of the learning of the relationship between key-pecking and food in pigeons who had suffered the ablation of the telencephalic structural (thalamic pigeons). There have been used nine adult pigeons (Columba livia) maintained at 80% of its ad libitum weight. The experiment I analysed the per
