1. Louis de Broglie's wave-particle duality: from textbooks’ blackboxes to a chain of reference presentation
Abstract We discuss the proposition of wave-particle duality made by Louis de Broglie in the period of 1922-1924 as well as the narratives of undergraduate Physics textbooks that introduce this topic. After a brief discussion on the nature of scientific reality, we point out the main theories, assumptions and techniques adopted by de Broglie to achieve the r

2. RELIABILITY-BASED MULTI-OBJECTIVE OPTIMIZATION APPLIED TO CHEMICAL ENGINEERING DESIGN
ABSTRACT Chemical engineering optimization represents a significant challenge due to the complexity of the mathematical models that are frequently required in this area. These models are normally associated with nonlinear equations that represent mass, energy, and momentum balances, which are submitted to physical, constitutive, environmental, and design lim

3. Industrialization in Sub-Saharan Africa and import substitution policy
This article aims to contribute to the understanding of the process of import substitution in Sub-Saharan Africa. The process of industrialization in Sub-Saharan Africa occurred in two phases: a first step, even very early during the colonial regime began around the 1920s and ended in the late forties; a second phase of industrialization began in the late fi

4. Una aplicación del teorema de conservacion de la energía como problema integrador
It is shown here the solution of a problematic situation in context, which is quite different from the exercises solved by the students usually. It is framed in Rich Problems in Context's strategy of solution, in which the students are involved actively and reliably for giving the answer. This problematic situation was presented to students of Bachelor in Ph

5. Anomalias de mercado : a estrategia de impulso e do volume no Mercado de acões brasileiro
Several studies have been and continue to be conducted with the aim of identifying factors that are responsible for abnormal results in the capital market. Among the investors risk averse, there are those who follow a momentum strategy. This implies that stocks that are rising will continue to rise and stocks that are falling will continue to fall, or simply

6. Simulação semi-empírica de refrigeradores domésticos : [dissertação]
In this work a computer program to simulate the thermodynamic performance of a specific household refrigerator, running both in steady-state and in cycling transient conditions, was developed. The computer program was developed based on the fundamentals principles of mass, energy and momentum conservation. Empirical parameters derived from experiments were i

7. Trajectory planning of jumping over obstacles for hopping robot
Trajectory planning strategy is proposed to jump over an obstacle integrated three various dynamics in one-legged multi-joint hopping robot. A concept of inertia matching ellipsoid and directional manipulability are extended to optimize take-off postures. Optimized results have been used to plan hopping trajectory. Aimed at the sensitivity of motion trajecto

8. The role of crossing symmetry for a low energy pion-nucleon scattering from dispersive method
The slow convergence of chiral perturbation theory for heavy baryons (HBChPT) suggests that any attempt to unitarize the amplitude following from this method will fail to describe the experimental phase shifts. However, it was possible to obtain a ChPT pion nucleon amplitudes respecting exact unitarity relation by using the Inverse Amplitude Method (IAM), bu

9. An empirical investigation on the influence of the past stock prices performance on Market to Book Value Multiples / Uma investigação empírica da influência do desempenho passado das ações sobre múltiplos preço-valor patrimonial
Na literatura encontram-se evidências de momento, ou seja, as ações vencedoras (aquelas que apresentaram no período anterior à formação da carteira os melhores retornos) tendem a ter o melhor desempenho num horizonte de até um ano e ações perdedoras (aquelas que apresentaram os piores retornos) tendem a ter o pior desempenho no mesmo período. Este

10. CONSISTÊNCIA NO CÁLCULO PERTURBATIVO: A ELETRODINÂMICA QUÂNTICA E A ANOMALIA AVV / CONSISTENCY IN THE PERTURBATIVE CALCULATION: THE QUANTUM ELETRODYNAMIC AND THE AVV ANOMALY
We use a very general calculational method, concerning the divergences manipulations and calculations, in order to treat the perturbative solution of quantum electrodynamics (QED), at the one loop level, as well as to study the perturbative origin of the axial triangle anomaly related with the electromagnetic decay of the neutral pion. Within the context of

11. Simulação computacional de eventos termo-hidraulicos transitorios em multicircuitos com multibombas
PANTERA-2 (from Programa para Análise Termo-hidráulica de Reatores a ÁguaProgram for Thermal-hydraulic Analysis of Water Reactors, Version 2), whose fundamentals are described in this work, is intended to carry out rod bundle subchannel analysis in conjunction with multiloop simulation. It solves simultaneously the conservation equations of mass, axial an

12. Modelagem fenomenologica e simulação bidimensional da fluidodinamica de reatores de leito fluidizado circulante
Circulating Fluidized Bed (CFB) reactors are used in a variety of industrial applications especially related to combustion and catalytic cracking. The fluid dynamic prediction of CFB is fundamental in its development and optimisation. In this work, a computer code for the simulation of the fluid dynamics of Circulating Fluidized Bed Reactors was developed. T
