Attitude stabilization of a rigid spacecraft in the geomagnetic field
(Elsevier B.V., 2007-01-01)
An analytical method is proposed to study the attitude stability of a triaxial spacecraft moving in a circular Keplerian orbit in the geomagnetic field. The method is developed based on the electrodynamics effect of the ...

The militarization of the urban sky in Santiago de Chile: the vision multiple of a video-surveillance system of aerostatic balloons
(2021)
Under a climate of insecurity, two of the wealthiest municipalities in Chile implemented a controversial system of aerostatic balloons equipped with next-generation cameras for urban surveillance. The municipalities sought ...
Drug-coated balloon used to treat in-stent restenosis of the renal arteryTratamento da recidiva de reestenose intra-stent renal por angioplastia com balão farmacológico
(2018-01-01)
During recent years, drug-coated balloons (DCBs) have emerged as a promising therapeutic option. DCBs directly transfer antiproliferative drugs to the arterial wall in order to decrease myointimal hyperplasia. We describe ...
Intercomparison of in situ water vapor balloon-borne measurements from Pico-SDLA H2O and FLASH-B in the tropical UTLS
(2016-03-21)
In this paper we compare water vapor mixing ratio measurements from two quasi-parallel flights of the Pico-SDLA H2O and FLASH-B hygrometers. The measurements were made on 10 February 2013 and 13 March 2012, respectively, ...
Dosimetria da braquiterapia por Califórnio-252 associada à captura de nêutrons pelo Boro com balão moderador aplicada ao Glioblastoma multiforme
(Universidade Federal de Minas GeraisUFMG, 2013-04-09)
Glioblastoma multiforme is a highly infiltrative tumor and, even with technological advances, the treatment for the control of infiltrations and local metastases is still a challenge. In order to evaluate alternatives for ...
Evolutionary process modeling with Bayesian inference of Spodoptera frugiperda ballooning and walking dispersal in Bt and non-Bt cotton plant mixtures
(2021-01-01)
Transgenic crops expressing Bacillus thuringiensis Berliner (Bt) have been cultivated throughout the world as a great technological tool for developing integrated pest management. We hypothesized that artificial landscapes ...
Evidence of horizontal and vertical transport of water in the Southern Hemisphere tropical tropopause layer (TTL) from high-resolution balloon observations
(2016-09-29)
High-resolution in situ balloon measurements of water vapour, aerosol, methane and temperature in the upper tropical tropopause layer (TTL) and lower stratosphere are used to evaluate the processes affecting the stratospheric ...
