Study of Optical Absorption property of the composite Polypropylene/Yellow beryl submitted to several doses of gamma-radiation.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
Yellow Beryl was obtained from Teófilolo Othoni, state of Minas Gerais, and added into a
matrix of Polipropileno (PP) made by Braskem. Here we have investigated the property of
optical absorption (OA) of this composite ...
Proton radiation effects on the self-aligned triple gate SOI p-type tunnel FET output characteristic
(2017-11-15)
This paper reports for the first time the study of radiation effects on triple gate SOI tunnel FETs. In this work, devices with 1 μm width and three different channel lengths were exposed to a 600 keV proton radiation ...
Monte Carlo simulation applied in total reflection X-ray fluorescence: Preliminary results
(2013-05-20)
The X-ray Fluorescence (XRF) analysis is a technique for the qualitative and quantitative determination of chemical constituents in a sample. This method is based on detection of the characteristic radiation intensities ...
Analysis of hourly global, direct and diffuse solar radiations attenuation as a function of optical air mass
(Elsevier B.V., 2014-01-01)
The objective of this work is to verify the attenuation caused by atmospheric constituents through the relationship between global, direct and diffuse solar radiation with respect to optical air mass. The optical air mass ...
Transfers between the Lagrangian points and the primaries considering radiation pressure
(2016-01-01)
The idea of the present paper is to study transfers in the restricted three-body problem considering the effects of the radiation pressure in the trajectory of the spacecraft in a bi-impulsive maneuver. Three systems of ...

(Univelt Inc, 2016-01-01)
The idea of the present paper is to study transfers in the restricted three-body problem considering the effects of the radiation pressure in the trajectory of the spacecraft in a bi-impulsive maneuver. Three systems of ...
Feed variation and biometrical factors in tilapias (Oreochromis niloticus) exposed to 60Co gamma radiation
(2016-06-17)
Ionizing radiation has been widely used for cancer treatment and diagnostic exams in medicine, besides being used in the fields of energy generation and industry. This work aimed to verify the occurrence of biological ...
Downward atmospheric longwave radiation in the city of são paulo
(2009-05-25)
This work evaluates objectively the consistency and quality of a 9 year dataset based on 5 minute average values of downward longwave atmospheric (LW) emission, shortwave radiation, temperature and relative humidity. All ...
Influence of nonlinear effects on the acoustic levitation of small spheres
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the nonlinear characterization of a single-axis acoustic levitator and the analysis of the influence of nonlinear effects on the acoustic levitation of small spheres. First, the nonlinear characterization ...
Low temperature performance of proton irradiated strained SOI FinFET
(2017-06-29)
This paper studies for the first time the low temperature characteristics of strained SOI FinFETs submitted to proton irradiation. Both types of transistors, nMOS and pMOS, were analyzed from room temperature down to 100K, ...
