Mapping the density of particles over the surface of asteroid (101955) Bennu
(2017-01-01)
In the present work we study the motion of particles near the surface of Bennu. An application of the results is to give assistance for the selection of the sample site. Considering the gravitational potential given by the ...
Permanent Magnet Hall Thruster for satellite orbit raising with low power energy consumption
(2008-12-01)
Electric propulsion is now a succeful method for primary propulsion of deep space long duration missions and for geosyncronous satellite attitude control. Closed Drift Thruster, so called Hall Thruster or SPT (Stationary ...

Bimodal chemical evolution of the Galactic disk and the Barium abundance of Cepheids
(International Astronomical UnionLijiang, 2013)
In order to understand the Barium abundance distribution in the Galactic disk based on Cepheids, one must first be aware of important effects of the corotation resonance, situated a little beyond the solar orbit. The thin ...
Study on the Curcumin dynamics and distribution through living biofilms
(2013-05-30)
Human oral cavity is colonized by a wide range of microorganisms, often organized in biofilms. These biofilms are responsible for the pathogenesis of caries and most periodontal diseases. A possible alternative to reduce ...

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 ...
