The paper analyzes the studies of incoherently scattered ionospheric radio signals of long duration. The depolarization of the incoherently scattered signal was experimentally of incoherently scattered detected, which is due to the spatial variation of th... see more

We present a concept for using long-wavelength broadband radio continuum observations of spiral galaxies to isolate magnetic structures that were only previously accessible from short-wavelength observations. The approach is based on combining the RM Synt... see more

Knowing how the ambient medium in the vicinity of active galactic nuclei (AGNs) is shaped is crucial to understanding generally the evolution of such cosmic giants as well as AGN jet formation and launching. Thanks to the new broadband capability now avai... see more

Electroencephalography (EEG) is a method for recording the brain's electrical activity through electrodes placed on the scalp's surface. The amplitude of the EEG signal is in the 40–100 V range, with the five main frequencies in the 0 to 100 Hz range. The... see more

Cirrus cloud is one of the most commonly occurring cloud types globally. The clouds are found mainly to consist of floating ice crystals, which can reflect strongly incoming radiation. Lidar measurements provide an opportunity to study the microphys... see more

The purpose of this research is to make a learning design on Faraday’s Induction Law using a PhET Faraday’s Electromagnetic Lab simulation and to investigate the effectiveness of the design on students' understanding. Descriptive research was used as the ... see more

We review the main aspects of the life of Michael Faraday and some of his main scientific discoveries. Although these aspects are well known and covered in many extensive treatises, we try to illustrate in a concise way the two main “wonders” of Faraday’s... see more

O “motor” elétrico de Michael Faraday (1791-1867) é versado como o precursor dos motores elétricos atuais e um equipamento interessante no estudo introdutório do assunto. Um trabalho anterior divulgou uma montagem deste motor mais bem adaptada aos ambient... see more
