Dose evaluation in medical staff during interventional radiology procedures
(2015-01-01)
Interventional Radiology is the radiology modality that provides the highest dose values to medical staff. Recent researches show that personal dosimeters may underestimate dose values in interventional physicians, especially ...
UV dose investigation for imersed lamp purifier for electronic ballast UV lamps design
(2014-01-01)
This paper presents a methodology of an electronic ballasts design for UV lamps filtering system, providing adjustable UV dose in order to ensure the inactivation of microorganisms' reproduction that are harmful to human ...
Modelling radiation and energy balances with Landsat 8 images under different thermohydrological conditions in the Brazilian semi-arid region
(Spie-int Soc Optical Engineering, 2015-01-01)
Four Landsat 8 images were used together with a net of seven agro-meteorological stations for modelling the large-scale radiation and energy balances in the mixed agro-ecosystems inside a semi-arid area composed by irrigated ...
Estimation of the radiation hazard to a spacecraft passing the van allen belts in a low thrust transfer
(2017-01-01)
A spacecraft transfer from a low Earth orbit to outside the Earth sphere of influence using solar electric propulsion is considered. The spacecraft crosses the Van Allen belts many times during the transfer, what can damage ...

(Universidade Estadual Paulista (Unesp), 2015-09-23)
The work about ionizing and non-ionizing radiation was carried out in the form of a questionnaire of 12 questions about knowledge of radiation, being interviewed elementary school students, high school and soldiers of ...
Surface temperature estimated with Landsat 8 images and geostatistical tools in the northwestern Sao Paulo state
(Spie-int Soc Optical Engineering, 2017-01-01)
In the northwestern side of Sao Paulo state, irrigated crops are replacing natural vegetation, bringing importance for the development and applications of tools to quantify the energy and water balances. Remote sensing ...
The BIOSUN project: an astrobiological approach to study the origin of life
(International Astronomical UnionFlorianópolis, 2013)
During the early ages of the Earth the magnetic activity
of the young Sun was much stronger than that
of the present Sun, in particular for radiation emitted
below 1700 ˚A. Such enhanced radiation fluxes
could play a ...
