Runaway electron acceleration is the keystone process responsible for the production of energetic radiation by lightning and thunderstorms. In the laboratory, it remains undetermined if runaway electrons are merely a consequence of high electric fields produced at the ionization fronts of electrical discharges, or if they impact the discharge forma...
Background
With the COVID-19 pandemic, thousands of children had their dental care interrupted or postponed, generating a pent-up demand for primary care. To minimize the impact of this outage, information and communication technologies (ICT) could be an alternative. The aim of this study is to elucidate the impact of implementing the ICTs in prima...

O remix tem ocupado um papel de interlocução cultural importante quando o assunto é originalidade, autoria, assinatura, apropriação, inapropriação e desapropriação, pois entre samplings e deslocamentos contextuais de vozes e sonoridades, o resultado estético e/ou a mensagem comunicacional de um remix normalmente entra em processo de crise identitár...
The remix has played an important cultural dialogue role when it comes to originality, authorship, signature, appropriation, inappropriation and expropriation, because between samplings and contextual displacement of voices and sounds, the aesthetic result and/ or communicational message of a remix usually triggers an identitarian crisis. Who owns...

The main goal of this article is to map and review real time video streaming collaborative softwares, in order to analyze platforms that are also able to edit films. Real time high resolution film transmission (4k, 8k or above) results in the excess of data generated and, consequently, in a high value for investment in editing, storage and content...
