Developing new radiotherapy techniques using linac based gamma radiation sources
(2007-12-01)
A major challenge in cancer radiotherapy is to deliver a lethal dose of radiation to the target volume while minimizing damage to the surrounding normal tissue. We have proposed a model on how treatment efficacy might be ...
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 ...
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 ...
Radiative Omega(-)->Xi(-)gamma decay and physics beyond the standard model
(World Scientific Publ Co Pte Ltd, 1997-01-01)
We investigate the impact of new physics beyond the Standard Model to the s --> d gamma process, which is responsible for the short-distance contribution to the radiative decay Omega-( )--> Xi(-) gamma. We study three ...
Postharvest conservation of 'Tommy Atkins' mango fruit influenced by gamma radiation, wax, hot water, and refrigeration
(2004-02-01)
It was aimed to extend the postharvest conservation of 'Tommy Atkins' mango fruits harvested in break maturity stage. Fruits were submitted at the following treatments: hot water treatment (55°C for 5 minutes) and benomyl ...
Using solar radiation pressure to maneuver a spacecraft in the triple asteroid 2001SN263
(2016-01-01)
The number of missions which with an asteroid as a target has increased and this type of exploration will become even more frequent in the future. Space missions require high costs and methods that may reduce them should ...
USING SOLAR RADIATION PRESSURE TO MANEUVER A SPACECRAFT IN THE TRIPLE ASTEROID 2001SN(263)
(Univelt Inc, 2016-01-01)
The number of missions which with an asteroid as a target has increased and this type of exploration will become even more frequent in the future. Space missions require high costs and methods that may reduce them should ...
Study of the effects of exposure to ionizing irradiation on the materials used for dental restoration
(Medimond S R L, 2002-01-01)
A quantitative study was made about the effects caused by ionizing irradiation on materials used for dental restoration (amalgams, compound resins and compomere), aiming to alleviate in bearers of head and neck cancer, the ...
Searching for orbits around the triple asteroid 2001SN263
(2017-10-25)
The asteroid 2001SN263 is one of the possible targets of a proposed mission that would be the first Brazilian exploration in deep space, the Aster Mission. This asteroid is composed by three bodies: Alpha, Beta, and Gamma, ...
White and green jadeite characterization by thermoluminescence.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
Except for gemologically or industrially important silicate minerals, a large number of
other natural silicate minerals have been investigated only concerning
geological/mineralogical aspects. Jadeite is a silicate mineral ...
