1. Electromagnetic Transients in Multiconductor Transmission Lines
Abstract The theory of multiconductor transmission lines is based on the principle of superposition. According to this principle, any electric or magnetic field can be represented as the sum of individual electric or magnetic fields. This theory is used to analyze and design electrical systems involving multiple conductors. In this work, the procedures for a

2. Problemas de Relojes. Ejemplos Históricos y Consideraciones Didácticas
We approach a classical Mathematical problem: that of computing the time passed, from a given moment, until the hands of a clock reach certain position. In particular, we focus on the case when the required position is the superposition of both hands. In this paper, we present some examples from classic and nineteenth century texts presenting different conte

3. Inserção de tópicos de física quântica no ensino médio através de uma unidade de ensino potencialmente significativa
It has become a challenge to high school teachers to include contents of quantum physics in the school curriculum not only for the lack of due preparation but for the scarcity of incentive. In spite of available educational resources, teachers seldom feel ready to approach such contents in the classroom. Furthermore, the present high school curriculum as wel

5. Método da superposição modificado como uma nova proposta de atribuição de responsabilidades sobre distorções harmônicas
Orientações contidas em documentos aprovados pela ANEEL e ONS contemplam, dentre outros indicadores de qualidade da energia elétrica, a temática das distorções harmônicas. Tais textos abordam, no contexto das distorções harmônicas, distintos assuntos vinculados com: definições, procedimentos de medição, valores de referência, etc. À luz desta

6. Montagem de uma disciplina experimental: contribuição para a química geral
The purpose of this paper is to present a classification criterion for general chemistry experiments departing from a survey of 35 years of the experimental general chemistry discipline at the Chemistry Institute - UNICAMP. It is shown that by considering the most remarkable characteristics of an experiment and classifying it under Conceptual, Fundamental, M

7. Multiaxial fatigue applied to evaluation of crankshafts s life / Fadiga multiaxial aplicada à avaliação da vida de virabrequins
O virabrequim é um dos principais componentes do motor de combustão interna e sua função é, em conjunto com a biela, transformar o movimento de translação do pistão em movimento de rotação. Como sofrem carregamentos cíclicos durante toda sua vida útil, o principal tipo de falha de um virabrequim é por fadiga. Porém, por estarem sujeitos a carre

8. Gas de Bose diluido fracamente confinado / Dilute Bose gas weakly confined
A critical study of atomic Bose-Einstein condensates (BECs) is presented. Taking as a starting point the physics of the free gas, we study the effect of weakly confining potentials. Two cases were studied in detail: i) an atomic gas in a finite square well potential with a few bound states; and ii) a system confined in two-dimensions by an isotropic harmonic

9. Modelo de Jaynes-Cummings completo de dois fótons: estudo e aplicações / Jaynes-Cummings model complete two photons: study and applications
In this work we have studied the two photon Jaynes-Cummings model to describe the interaction of a three-level atom in the configuration with a single-mode of a cativy-field. We have used the effetive and full microscopic Jamiltonian approach to compare the results obtained in these tow descriptions. We employed the two-photon Jaynes-Cummings model int the f

10. Conservação ambiental e direitos multiculturais : reflexões sobre justiça / Protected areas and multicultural right : reflections concerning justice
From an interdisciplinary approach, focused on human sciences, this work is concerned with action situations that have occurred in protected environmental areas. We have selected two protected areas that have different presuppositions in relation to the possibility of conservation and human presence: Parque Nacional do Jaú (Jaú National Park and Reserva de

11. Entre modernidade e tradição : desenvolvimento comunitário sustentável em Ererê, Pará
The work of professionals from development research institutions , through community- based projects, has taken a connecting position for introducing modernity into the local communities where the lack of development can be considered as a risk to the nature conservation. The international management approach of the natural resources, also related to the obj

12. Controle de vibrações em edifícios submetidos à ação de cargas dinâmicas utilizando amortecedor de massa sintonizando na forma de pêndulo / Vibration control of structures subjected to dynamic loads using tuned pendulum-shaped mass dampers
The ongoing progress of structural analyses and dimensioning, in addition to the continuous advancements in building techniques and material, has made it possible to build taller and more slender structures every day. These structures are also more vulnerable to excessive vibrations caused by dynamic loads like earthquakes, winds, waves, intense traffic, and
