A numerical study of open atmospheric balloon dynamics
(American Institute of Physics, 2003-10)
The dynamics of open balloons in an atmosphere may be studied with a body-fluid coupled model. A numerical approach is required to solve the corresponding equation set. Solutions under different conditions are obtained ...
Thermal behaviour studies of solid state compounds of cinnamylidenepyruvate with trivalent lanthanides and yttrium (III) in an atmosphere of CO2
(Editora Unesp, 2002-01-01)
Solid state cinnamylidenepyruvate of trivalent lanthanides (except for promethium) and yttrium, were prepared. Thermogravimetry, derivative thermogravimetry (TG, DTG), differential scanning calorimetry (DSC), X-ray diffraction ...

(2002-12-01)
Solid state cinnamylidenepyruvate of trivalent lanthanides (except for promethium) and yttrium, were prepared. Thermogravimetry, derivative thermogravimetry (TG, DTG), differential scanning calorimetry (DSC), X-ray diffraction ...
Simulation of transports and concentration of radionuclides by dynamics process in the atmosphere in eventual accidents in the Angra 1 and Angra 2 Power Plants
(Associa????o Brasileira de Energia Nuclear, 2021)
Regional atmospheric dynamics govern interannual and seasonal stable isotope composition in southeastern Brazil
(2019-12-01)
Climatic factors controlling seasonal and interannual changes of stable isotope composition in precipitation remains understudied across the tropics. Daily isotopic measurements of rainfall (2014–2017, Rio Claro, Southeast ...
Dynamic modeling, simulation and control of hybrid energy storage system based on compressed air and supercapacitors
(Institute of Electrical and Electronics Engineers, 2013-02)
In this paper, the dynamic modeling and the control design of hybrid energy storage system based on compressed air and supercapacitors (CAES-SC) is presented, which converts excess energy from the power supply to stored ...
A comparative study on thermal behavior of solid-state light trivalent lanthanide isonicotinates in dynamic dry air and nitrogen atmospheres
(Springer, 2016-07-01)
Characterization, thermal stability, and thermal decomposition of light trivalent lanthanide isonicotinates Ln(L)(3)center dot 2H(2)O (Ln = La to Gd, except Pm; L = isonicotinate) were investigated employing simultaneous ...
The role of the observed tropical convection in the generation of frost events in the southern cone of South America
(COPERNICUS GESELLSCHAFT MBH, 2008)
Based on previous results obtained from observations and linear wave theory analysis, the hypothesis that large-scale patterns can generate extreme cold events in southeast South America through the propagation of remotely ...
Chaco low-level jet events characterization during the austral summer season
(Wiley Blackwell Publishing, Inc, 2002-12-27)
Previous studies showed a relationship between convection maxima and the convergence of vapor flux over southeastern South America. Nicolini and Saulo [2000] explored the hypothesis of an intensification of this mutual ...
Temperature variability and soil–atmosphere interaction in South America simulated by two regional climate models
(Springer, 2019-02)
Interannual variability of surface air temperature over South America is investigated and, based on previous studies, thought to be partly the consequence of soil–atmosphere interaction. Annual and monthly averages of ...
