Um modelo sócio-interacionista para a formação continuada de professores
(Congresso Estadual Paulista sobre Formação de Educadores, 2009) [Trabalho apresentado em evento]
Two dimensional computer simulation of plasma immersion ion implantation
(Brazilian Journal of Physics, 2004-12-01) [Trabalho apresentado em evento]
The biggest advantage of plasma immersion ion implantation (PIII) is the capability of treating objects with irregular geometry without complex manipulation of the target holder. The effectiveness of this approach relies ...
Pseudospin and spin symmetries in the relativistic harmonic oscillator
(Blejske Delavnice iz Fizike - Bled Workshops in Physics, 2006-12-01) [Trabalho apresentado em evento]
We compute the analytical solutions of the generalized relativistic harmonic oscillator in 1+1 dimensions, including a linear pseudoscalar potential and quadratic scalar and vector potentials which have equal or opposite ...
Absence of Klein's paradox for massive spinless bosons coupled by a nonminimal vector interaction
(Proceedings of Science, 2009-12-01) [Trabalho apresentado em evento]
A few properties of the nonminimal vector interaction in the Duffin-Kemmer-Petiau theory in the scalar sector are revised. In particular, it is shown that the nonminimal vector interaction has been erroneously applied to ...
Plasma-polymerized hexamethyldisilazane treated by nitrogen plasma immersion ion implantation technique
(Xix Latin American Symposium on Solid State Physics (slafes), 2009-01-01) [Trabalho apresentado em evento]
This paper describes the effect of nitrogen Plasma Immersion Ion Implantation (PIII) on chemical structure, refraction index and surface hardness of plasma-polymerized hexamethyldisilazane (PPHMDSN) thin films. Firstly, ...
Polyurethane coating with thin polymer films produced by plasma polymerization of diglyme
(Xix Latin American Symposium on Solid State Physics (slafes), 2009-01-01) [Trabalho apresentado em evento]
Aqueous-based polyurethane dispersions have been widely utilized as lubricants in textile, shoes, automotive, biomaterial and many other industries because they are less aggressive to surrounding environment. In this work ...
Wettability, optical properties and molecular structure of plasma polymerized diethylene glycol dimethyl ether
(Xix Latin American Symposium on Solid State Physics (slafes), 2009-01-01) [Trabalho apresentado em evento]
Modern industry has frequently employed ethylene glycol ethers as monomers in plasma polymerization process to produce different types of coatings. In this work we used a stainless steel plasma reactor to grow thin polymeric ...
Amorphous hydrogenated carbon films treated by SF(6) plasma
(Xix Latin American Symposium on Solid State Physics (slafes), 2009-01-01) [Trabalho apresentado em evento]
This work was performed to verify the chemical structure, mechanical and hydrophilic properties of amorphous hydrogenated carbon films prepared by plasma enhanced chemical vapor deposition, using acetylene/argon mixture ...
Efficiency of geotextile filters in dewatering wastes (sludge) from water treatment works
(Geosynthetics, Vols 1-4, 2006-01-01) [Trabalho apresentado em evento]
This paper evaluates the efficiency of geotextile filters for sludge from a compact water treatment plant (WTP). The key aspects required in the methodology of selection and designing geotextile filters for sludge from ...
Um estudo sobre a corrosão aquosa de ligas de alumínio 7xxx submetidas a diferentes tratamentos térmicos
(Anais - 10th Semiario de Metals nao Ferrosos, 2002-12-01) [Trabalho apresentado em evento]
This job aim has been to study the aqueous corrosion of the 7xxx heattreatable aluminium alloys, used in the aeronautical industry. The 7010, 7050 and 7475 alloys, have been supplied in the T7 condition and submitted to ...
