Equatorial F region vertical plasma drifts during solar maxima
(American Geophysical Union, 1989-09-01)
Incoherent scatter radar measurements at Jicamarca are used to study the effects of large solar fluxes and magnetic activity on the F region vertical plasma drifts. The average drifts from the two last solar maxima are ...
How are emerging flux, flares and CMEs related to magnetic polarity imbalance in MDI data?
(Springer, 2003-12)
In order to understand whether major flares or coronal mass ejections (CMEs) can be related to changes in the longitudinal photospheric magnetic field, we study 4 young active regions during seven days of their disk passage. ...
Estudo do efeito de fluxos na soldagem ATIG de alumínio
(Universidade Federal de Minas GeraisUFMG, 2007-05-18)
The feasibility of using ATIG (active flux TIG) welding for surface oxide removal in aluminum welding with direct polarity was evaluated. The influence of the flux on different conditions of specimen surface, variations ...
Measurement and control of greenhouse gas emissions from beef cattle feedlots
(2013-05-01)
Emission of greenhouse gases (GHGs), including nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from open beef cattle feedlots is becoming an environmental concern; however, scientific information on emissions ...
