13. Avaliação de personalidade em transtorno afetivo bipolar por meio do estudo de pares de irmãos / Personality traits and impulsivity in bipolar disorder: a sib-pair study
Recent studies have shown that euthymic patients with bipolar disorder present higher scores on impulsivity, novelty seeking, harm avoidance and selftranscendence and lower scores on self-directedness and cooperativeness than healthy controls. However it is unclear whether specific personality traits are vulnerability markers for bipolar disorder or represen

14. Comportamento infantil conhecido como hiperatividade: consequência do mundo contemporâneo ou TDAH?
Child behavior known as hyperactive and usually diagnosed as ADHD (Attention deficit and hyperactivity disorder) is focused, with the purpose of verifying to what extent its origins can be related to excess of stimulation to which children are exposed in contemporary world. The hypothesis is that disorganized, disruptive and impulsive behaviors observed in m

15. Investigação teórico-experimental sobre a resposta de aterramentos elétricos frente a correntes de descargas atmosféricas
This work presents the results of an experimental investigation about the behavior of grounding electrodes subjected to low intensity impulsive currents, whose waveforms are similar to the lightning ones. Basically the results consist in the response of electrodes, in terms of developed voltage, to the injection of impulsive currents, considering soils with

16. A unified discrete-time approach to the state space representation of aeroelastic systems.
In complex flow situations, it is common to use numerical tools to evaluate the aerodynamic unsteady behavior. The present work presents an alternate formulation for the state space representation of aeroelastic systems based on digital control theory that is shown to be effective and accurate for the coupling of numerical solutions with such systems. The ap

17. A concepção dos professores diante do transtorno de déficit de atenção e hiperatividade em contexto escolar: um estudo de caso.
A presente pesquisa tem como objetivo analisar a concepção do professor sobre o TDAH (Transtorno de Déficit de Atenção e Hiperatividade) na identificação, caracterização e gestão dos comportamentos desatento, hiperativo e impulsivo dos alunos em sala de aula. Os sujeitos da pesquisa foram quarenta professores que lecionam nas classes de educação

18. Projeto, construÃÃo e caracterizaÃÃo de um amortecedor ativo controlado por atuador piezoelÃtrico / Design, construction and characterization controlled by Piezoelectric Actuato
This thesis presents the design methodology, the construction of a prototype and the experimental validation of an active vibration damper witch is controlled by a piezoelectric actuator. The proposed device has two flexible metallic bellows connected to a rigid reservoir filled with a viscous fluid. When one of the bellows is connected to a vibrating struct

19. Associação entre impulsividade, idade do primeiro consumo de álcool e abuso de substâncias psicoativas em adolescentes de uma região do sul do Brasil
Introdução: Os problemas advindos dos transtornos por uso de substâncias (TUS) apresentam alta prevalência tanto em nível mundial quanto no Brasil e se destacam por atingirem principalmente adolescentes e adultos jovens, ocasionando alto impacto econômico e social. Os fatores de risco que levam ao início e à evolução de tais transtornos são invest

20. A biologia moral: a constituição do sujeito (des)atento / The moral biology of attention: the constitution of the (in)attentive individual
The objective of this work is to analyze the constitution of the attentive and inattentive individual within the historical process of the moral biologisation of attention. This thesis divides the history of the moral biology of attention into three main phases: the second half of the eighteenth century; the second half of the nineteenth century; the last th

21. "Consumo de álcool e outras drogas e impulsividade sexual entre agressores sexuais" / Alcohol and drug consumption and sexual impulsivity among sexual offenders
INTRODUCTION: Sexual violence is an important public health problem. In São Paulo, about 5% of male prison inmates are serving a sentence for a serious sexual offense. In Brazil and other countries, many sexual offenders will return home without any psychosocial interventions to prevent recidivism. The aim of this study was to evaluate the role of alcohol a

22. Os conflitos interpessoais na relação educativa
This work consists in a case study, in which we investigated whether the school environment indeed influences on the students sociomoral formation not only while individuals, but also as groups. The relations established among themselves and the way they dealt with their conflicts became our focus of interest, as well as how the children interpret and solve

23. Evidence for a dysfunctional prefrontal circuit in patients with an impulsive aggressive disorder
Humans with lesions to the orbital/medial prefrontal cortex and interconnected areas display impulsive aggressive behavior. To examine further the relationship between impulsive aggression and orbital/medial prefrontal dysfunction, we measured the behavioral performance of psychiatric patients with a disorder characterized by impulsive aggression, Intermitte

24. Brain serotonin dysfunction accounts for aggression in male mice lacking neuronal nitric oxide synthase
Genetically engineered mice with targeted disruption of the neuronal nitric oxide synthase (nNOS) gene established the inhibitory role of nitric oxide (NO) in male impulsive aggressive behavior. This was later confirmed by using selective nNOS inhibitors in male wild-type mice. The molecular mechanisms accounting for the aggressive behavior caused by th
