Deactivation kinetics for the conversion of dimethyl ether to olefins over a HZSM-5 zeolite catalyst
(2016-11-16)
A deactivation kinetic equation for the conversion of dimethyl ether (DME) to olefins (DTO process) has been established. The catalyst has been prepared with a HZSM-5 zeolite (SiO2/Al2O3 ratio of 280) agglomerated with ...

Cloning, purification and characterization of two components of phenol hydroxylase from Rhodococcus erythropolis UPV-1
(Springer, 2009-09-29)
Phenol hydroxylase that catalyzes the conversion of phenol to catechol in Rhodococcus erythropolis UPV-1 was identified as a two-component flavin-dependent monooxygenase. The two proteins are encoded by the genes pheA1 and ...
Application of the dual integrated force method to the analysis of the off-axis three-point flexure test of unidirectional composites
(SAGE Journals, 2015-03-13)
This paper shows the use of the dual integrated force method in the finite element method and its application to unidirectional composite laminates. This method was developed by SN Patnaik for isotropic materials, considering ...
Calculation of positron characteristics for elements of the periodic table
(IOP Publishing Ltd, 2011-01-10)
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the
periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the
electronic ...
Determining Flinders' bar correction by heeling the ship
(Spanish Society of Maritime Research (SEECMAR), 2013)
The aim of this article is to provide the compass adjuster with an innovative method of determining thelength of Flinders’ bar while the ship’s latitude remains unaltered. In this way the definitive compass ad-justment may ...
Effect of alkaline and autohydrolysis processes on the purity of obtained hemicelluloses from corn stalks
(Elsevier, 2012)
[EN]A study of the potential of autohydrolysis and alkaline extraction processes from corn stalks was performed
for high purity hemicellulose extraction. The influence of process parameters on the purity of
obtained ...

Effects of galanin subchronic treatment on memory and muscarinic receptors.
(Elsevier, 2015-05-07)
Las vías colinérgicas, que se originan en el prosencéfalo basal y son responsables del control de diferentes procesos cognitivos como el aprendizaje y la memoria también están reguladas por algunos neuropéptidos. Uno de ...
Effect of calcination/reduction conditions of Ni/La2O3–αAl2O3 catalyst on its activity and stability for hydrogen production by steam reforming of raw bio-oil/ethanol
(Elsevier, 2014-04-05)
The influence of calcination and reduction temperatures of Ni/La2O3–αAl2O3 catalyst used in the steam reforming of raw bio-oil was studied in the 550–850 °C range. The experiments were conducted by continuously feeding a ...
