En las investigaciones en Enseñanza de las Ciencias se plantea recurrentemente la necesidad de introducir conocimientos relativos a la Física cuántica en la escuela secundaria. Sin embargo, los aportes en relación a qué conceptos enseñar son escasos y con... see more

An analysis of classical mechanics in a complex extension of phase space shows that a particle in such a space can behave in a way redolent of quantum mechanics; additional dimensions permit ‘tunnelling’ without recourse to instantons and time/energy unce... see more

The ring model of the coupled oscillator has enormously studied from the perspective of quantum mechanics. The research efforts on this system contribute to fully grasp the concepts of energy transport, dissipation, among others, in mesoscopic and condens... see more

Objective Metabolomic analysis is extensively applied to identify sensitive and specific biomarkers capable of reflecting pathological processes and physical responses or adaptations. Exercise training leads to profound metabolic changes, manifested as de... see more

The aim of the paper is the mathematical modeling of nanotechnology problems of navigation based on generalizations of the Picard method. The Picard method for solving systems of ordinary differential equations, and its extensions on the basis of hyperlog... see more

A stochastic model of sound propagation in damping medium is proposed. It consists of: (1) Ito’s stochastic differential equation describing the sound propagation, (2) a potential which models the damping effects. However, due to presence of path integral... see more

Partindo do pressuposto de que a argumentação é uma dimensão inerente a todo discurso, este artigo tem por objetivo analisar como ela se dá pela mobilização do logos, do ethos e do pathos através da seleção de itens lexicais considerando todo o contexto e... see more
