Short-chain di-ureasil ormolytes doped with potassium triflate: Phase diagram and conductivity behavior
(2003-01-01)
Di-urea cross-linked poly(oxyethylene)/siloxane hybrids, synthesized by the sol-gel process and containing a wide concentration range of potassium triflate, KCF3SO3, have been analyzed by x-ray diffraction and differential ...
Enhancing The Description Of Ssle Data For Binary And Ternary Fatty Mixtures
(Elsevier Science BVAmsterdam, 2016)
Ab-initio and CVM calculations on the metastable fcc, hcp, and bcc Pb-Bi-Te and Pb-Bi-Po ternary systems.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
A molten Pb Bi alloy will be used as coolant in MYRRHA (Multi-purpose hybrid research reactor for high-tech applications), a prototype of an accelerator-driven nuclear fission reactor (“generation IV reactor”) that will ...
Study of the ℤ3 symmetry in QCD at finite temperature and chemical potential using a worm algorithm
(2013-04-24)
Traditional Monte Carlo simulations of QCD in the presence of a baryon chemical potential are plagued by the complex phase problem and new numerical approaches are necessary for studying the phase diagram of the theory. ...
Star forming, AGN and passive phases of galaxy evolution since z = 0.5 as told by SDSS data
(International Astronomical UnionFlorianópolis, 2013)
Our goal is to study the interplay between star forming,
AGN and passive phases of galaxy evolution.
For that we need a wide database of galaxy spectra,
binning the sample into stellar mass and redshift
bins to deal ...

(Soc Brasileira Quimica, 2009-01-01)
DEVELOPMENT of LIQUID-CRYSTALLINE SYSTEMS USING SILICON GLYCOL COPOLYMER and POLYETHER FUNCTIONAL SILOXANE. For the construction of the phase diagrams, the method of the aqueous titration was used. There were prepared 5 ...
On a control design to an AFM microcantilever beam, operating in a tapping-mode, with irregular behavior
(2011-12-01)
In last decades, control of nonlinear dynamic systems became an important and interesting problem studied by many authors, what results the appearance of lots of works about this subject in the scientific literature. In ...
Object oriented modeling of piston engines
(2001-12-01)
This work reports a conception phase of a piston engine global model. The model objective is forecast the motor performance (power, torque and specific consumption as a function of rotation and environmental conditions). ...
New 12kW three-phase 18-pulse high power factor AC-DC converter with regulated output voltage for rectifier units
(1999-12-01)
This work presents a new high power factor three-phase rectifier based on a Y-connected differential autotransformer with reduced kVA and 18-pulse input current followed by three DC-DC boost converters. The topology provides ...
