1. Determination of Electric and Magnetic Field Calculation Uncertainty in the Vicinity of Overhead Transmission Lines
Abstract This paper presents a new approach for uncertainty determination of the electric field intensity and magnetic flux density calculation in the vicinity of overhead transmission lines. The proposed method is based on the law of propagation of uncertainty as defined in the Guide to the expression of Uncertainty in Measurement. A mathematical model is d

3. Helicoidal single-layer cylindrical coil self-inductance evaluation : a didactic method
This paper presents a didactic mathematical method to evaluate the self-inductance of a nonmagnetic core single-layer cylindrical and helicoidal coil presenting voids between turns. This type of calculation, using Biot–Savart Law, is not usually presented in the traditional electromagnetic text books, but constitutes an excellent tool to show to the studen

7. Analise do significado e da evolução do conceito de força de Ampere, juntamente com a tradução comentada de sua principal obra dobre eletrodinamica / Analysis of the meaning and evolution of Ampere s force concept, together with a commented translation of his main work on electrodynamics
We present Ampère?s force between current elements and discuss in detail the magnitudes which appear in this law. We analyze the trajectory followed by Ampère in order to obtain his force between current elements. We show his first experiments, the initial formulations of his force, the experiments of Biot and Savart, and the in uence of Faraday?s experime

8. ASYMPTOTIC LINKING INVARIANTS FOR RKACTIONS IN COMPACT RIEMANNIAN MANIFOLDS / ÍNDICES DE ENLAÇAMENTO ASSINTÓTICO PARA AÇÕES DE RK EM VARIEDADES RIEMANNIANAS COMPACTAS
V.I. Arnold, in his paper The algebraic Hopf invariant and its applications published in 1986, considered a compact domain (ômega maiúsculo) in R3 with a smooth boundary and trivial homology and two divergence free vector fields X and Y in (ômega maiúsculo) tangent to the boundary. He defined an asymptotic linking invariant lk(X; Y ) and a Hopf invariant

9. Quantitative Modeling and Optimization of Magnetic Tweezers
Magnetic tweezers are a powerful tool to manipulate single DNA or RNA molecules and to study nucleic acid-protein interactions in real time. Here, we have modeled the magnetic fields of permanent magnets in magnetic tweezers and computed the forces exerted on superparamagnetic beads from first principles. For simple, symmetric geometries the magnetic fields
