Evolucionismo darwinista? Contribuições de Alfred Russel Wallace à teoria da evolução

open access: yesRevista Brasileira de História, 2014
Teria sido mesmo Charles Darwin o autor da teoria do processo evolutivo? Em suas pesquisas, Darwin discute mais a origem da seleção natural do que propriamente a origem das espécies.

COVID-19 lockdown impact on CERN seismic station ambient noise levels

open access: yesOpen Engineering, 2022
Seismic measuring stations do not only record seismic waves. They also pick up tremors caused by other factors: these are known as seismic background noise. In normal conditions, this environmental background is steady over a long time.

The width of the higgs boson decay into two photons in framework of nmssm with CP violation: one loop approximation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
The article considers the problem of the extension of standard model physics of elementary particles. We focus on nonminimal supersymmetric models. Nowadays this model is the most appropriate compared with other developed supersymmetric theories.

Fluid-Structure Interaction in a 3-by-3 Reduced-Scale Fuel Assembly Network

open access: yesScience and Technology of Nuclear Installations, 2010
We present experimental results on 9 reduced-scale fuel assemblies arranged in a network of 3 by 3, subjected to an axial flow. The objective is to analyse the fluid force induced by the motion of the central fuel assembly on the others fuel assemblies ...
