A novel rational harmonic balance approach for periodic solutions of conservative nonlinear oscillators
Beléndez Vázquez, Augusto - Gimeno Nieves, Encarnación - Álvarez López, Mariela Lázara - Gallego Rico, Sergi - Ortuño Sánchez, Manuel - Méndez Alcaraz, David Israel

Formato:	info:eu-repo/semantics/article
Enlaces:	An analytical approximate procedure for a class of conservative single degree-of-freedom nonlinear oscillators with odd non-linearity is proposed. This technique is based on the generalized harmonic balance method in which analytical approximate solutions have rational forms. Unlike the classical harmonic…

Linearized harmonic balancing approach for accurate solutions to the dynamically shifted oscillator
Beléndez Vázquez, Augusto - Rodes Roca, José Joaquín - Fuentes Rosillo, Rosa - García Llopis, Celia - Yebra Calleja, María Soledad - Pascual Villalobos, Inmaculada

Formato:	info:eu-repo/semantics/article
Enlaces:	The analytical approximate technique developed by Wu et al for conservative oscillators with odd nonlinearity is used to construct approximate frequency-amplitude relations and periodic solutions to the dynamically shifted oscillator. This nonlinear oscillator is described by an equation of motion…

Genotype × environment interaction for long-yearling weight in Canchim cattle quantified by reaction norm analysis.
MATTAR, M. - SILVA, L. O. C. da - ALENCAR, M. M. de - CARDOSO, F. F.

Formato:	Artigo em periódico indexado (ALICE)
Enlaces:	The objective of this study was to investigate the presence of genotype × environment interactions (G×E) for long-yearling weight in Canchim cattle (5/8 Charolais + 3/8 zebu) in Brazil using reaction norms (RN). The hierarchical RN model included the fixed…

Electrochemical methods to enhance the capacitance in activated carbon/polyaniline composites
Bleda Martínez, María Jesús - Peng, Chuang - Zhang, Shenguen - Chen, George Z. - Morallón Núñez, Emilia - Cazorla Amorós, Diego

Formato:	info:eu-repo/semantics/article
Enlaces:	Activated carbon/polyaniline composites have been prepared using different electrochemical methods: single-step potentiostatic polymerization, multiple-step potentiostatic polymerization, and potentiodynamic polymerization with the anodic potential limits being fixed at either 0.75 or 1 V (vs Ag/AgCl). The prepared composite samples were characterized…

Hybrid sol-gel conducting polymer synthetised by electrochemical insertion: tailoring the capacitance of polyaniline
Montilla Jiménez, Francisco - Cotarelo Méndez, María de los Ángeles - Morallón Núñez, Emilia

Formato:	info:eu-repo/semantics/article
Enlaces:	The templated growth of polyaniline through porous sol–gel films on ITO substrates has been performed. The polyaniline–silica composites have been synthesized by electrochemical reactive insertion in potentiodynamic and potentiostatic conditions. When the polymer is synthesized by potential step experiments, the…

Bifunctional Binols: Chiral 3,3'-Bis(aminomethyl)-1,1'-bi-2-naphthols (Binolams) in asymmetric catalysis
Nájera Domingo, Carmen - Sansano Gil, José Miguel - Saá Rodríguez, José Manuel

Formato:	info:eu-repo/semantics/article
Enlaces:	3,3'-Bis(dialkylaminomethyl)-1,1'-binaphth-2-ols (Binolams) have emerged during the last five years as very efficient chiral ligands in many enantioselective processes. Enantiomerically pure Binolams are easily accessible by means of a variety of methods, the most widely used being the so-called chiral Binol…
