Addressing students' difficulties with Faraday's law: A guided problem solving approach
(Amer Physical, 2014-06-30)
In traditional teaching, the fundamental concepts of electromagnetic induction are usually quickly analyzed, spending most of the time solving problems in a more or less rote manner. However, physics education research has ...
Response of the topological surface state to surface disorder in TlBiSe2
(IOP Publishing, 2015-02-24)
Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile ...
Occupational exposure to nano-TiO2 in the life cycle steps of new depollutant mortars used in construction
(IOP Publishing, 2015)
The present work is focused on the measurement of workers exposure to nano-TiO2 in the life cycle steps of depollutant mortars. It has been done in the framework of the SCAFFOLD project, which aims at the management of ...
Analysis of multivariate stochastic signals sampled by on-line particle analyzers: Application to the quantitative assessment of occupational exposure to NOAA in multisource industrial scenarios (MSIS)
(IOP Publishing, 2015)
In multisource industrial scenarios (MSIS) coexist NOAA generating activities with other productive sources of airborne particles, such as parallel processes of manufacturing or electrical and diesel machinery. A distinctive ...
The center of mass and center of charge of the electron
(IOP Publishing, 2015)
The goal of this contribution is to show that the hypothesis that the center of mass(CM) and the center of charge(CC) of a classical electron are two different points is only compatible with a relativistic description. The ...
Calibrating Analytical Models for Semilocal Strings
(IOP Publishing, 2015)
In this work we calibrate two different analytic models of semilocal strings by constraining the values of their free parameters. In order to do so, we use data obtained from the largest and most accurate field theory ...
Relativistic force between fast electrons and planar targets
(IOP Publishing, 2014-07-30)
The full retarded electromagnetic force experienced by swift electrons moving parallel to planar boundaries is revisited, for both metallic and dielectric targets, with special emphasis on the consequences in electron ...
Helmholtz Fermi surface harmonics: an efficient approach for treating anisotropic problems involving Fermi surface integrals
(IOP Publishing, 2014-06-09)
We present a new efficient numerical approach for representing anisotropic physical quantities and/or matrix elements defined on the Fermi surface (FS) of metallic materials. The method introduces a set of numerically ...
Cosmological constrains on fast transition Unified Dark Matter models
(IOP Publishing, 2015)
In this work we show the results obtained applying a Unified Dark Matter (UDM) model with a fast transition to a set of cosmological data. Two different functions to model the transition are tested, and the feasibility of ...
Application of Entropy and Fractal Dimension Analyses to the Pattern Recognition of Contaminated Fish Responses in Aquaculture
(MDPI, 2014-11)
The objective of the work was to develop a non-invasive methodology for image acquisition, processing and nonlinear trajectory analysis of the collective fish response to a stochastic event. Object detection and motion ...
