Simulación y validación del proceso de esterificación no catalítica de ácidos grasos libres que componen el aceite karanja
(Escuela Superior Politécnica de Chimborazo, 2021-08-24)
The objective of this work is to simulate and validate a non-catalytic esterification process of Free Fatty Acids (FFA), components of karanja oil (Pongamia pinnata), in order to process the data that will feed an Artificial ...
Phase analysis of seeded and doped PbMg1/3Nb2/3O3 prepared by organic solution of citrates
(1996-07-01)
PbMg1/3Nb2/3O3 (PMN) prepared by organic solution of citrates was analyzed by the Rietveld method to determine the influence of seeds and dopants on the perovskite and pyrochlore phase formation. It was observed that ...

Correlation of c-erbB-2 oncogene and p53 tumor suppressor gene with malignant transformation of hydatidiform mole
(Blackwell Publishing, 2006-06-01)
Considering the roles of c-erB-2 and p53 oncoproteins in tumor progression, we aimed to evaluate their expression in hydatidiform moles, and the possible predictive value of this immunoexpression in postmolar follow-up.Group ...
Nucleation and crystallization of titania nanoparticles in silica titania planar waveguides: A study by low frequency Raman scattering
(2004-07-28)
SiO2 (1-x) - TiO2 (x) waveguides, with the mole fraction x in the range 0.07 - 0.20 and thickness of about 0.4 μm, were deposited on silica substrates by a dip-coating technique. The thermal treatments at 700-900°C, used ...
