Effect of the glass substrate on the efficiency of the different orders that propagate in a transmission sinusoidal diffraction grating
Neipp López, Cristian - Sheridan, John T. - Márquez Ruiz, Andrés - Gallego Rico, Sergi - Ortuño Sánchez, Manuel - Beléndez Vázquez, Augusto - Pascual Villalobos, Inmaculada

Formato:	info:eu-repo/semantics/article
Enlaces:	In this work we study the effect of the glass substrate on the efficiencies of the different orders that propagate inside a transmission sinusoidal diffraction grating. Holographic optical elements are usually recorded on a photosensitive medium deposited on to a…

Corneal primary aberrations compensation by oblique light incidence
Espinosa Tomás, Julián - Mas Candela, David - Kasprzak, Henryk T.

Formato:	info:eu-repo/semantics/article
Enlaces:	The eye is not a centered system. The line of sight connects the fovea with the center of the pupil and is usually tilted in the temporal direction. Thus, off-axis optical aberrations, mainly coma and oblique astigmatism, are introduced at…

Reply to ‘Comment on “Approximation for the large-angle simple pendulum period”’
Beléndez Vázquez, Augusto - Rodes Roca, José Joaquín - Beléndez Vázquez, Tarsicio - Hernández Prados, Antonio

Formato:	info:eu-repo/semantics/article
Enlaces:	In their comment, Qing-Yin and Pei derived another analytical approximate expression for the large-angle pendulum period, which they compare with other expressions previously published. Most of these approximate formulas are based on the approximation of the original nonlinear differential equation…

Effects of a carbohydrate and a carbohydrate and casein protein beverages on recovery and performance of endurance cycling capacity
Cepero González, Mar - Rojas Ruiz, Francisco Javier - Geerlings, Arjan - Cruz Márquez, Juan Carlos de la - Romero Granados, Santiago - Boza Puerta, Julio José

Formato:	info:eu-repo/semantics/article
Enlaces:	The main aim of this study was to determine if short-term post exercise recovery, cycling performance and muscle damage were altered when consuming a carbohydrate-only beverage (CHO, 7% carbohydrate) versus a carbohydrate and casein protein beverage (CHO+P, 7% carbohydrate and…

Electrochemical reduction of perchloroethylene in aqueous media: influence of the electrode material
Sáez Bernal, Verónica - Esclapez Vicente, María Deseada - Frías Ferrer, Ángel - Bonete Ferrández, Pedro - González García, José

Formato:	info:eu-repo/semantics/article
Enlaces:	The electrochemical reduction of perchloroethylene (PCE) in water has been analyzed through voltammetric studies with a rotating disc electrode and controlled potential bulk electrolysis. The influence of the mass transport conditions and initial concentration on lead, copper and carbon electrodes…

Noise gratings in thick-phase holographic lenses
Beléndez Vázquez, Augusto - Fuentes Rosillo, Rosa - Fimia Gil, Antonio

Formato:	info:eu-repo/semantics/article
Enlaces:	An experimental analysis of noise gratings in holographic lenses is presented. Lenses are recorded as thick-phase holograms in bleached silver halide emulsion. The authors calculated noise grating efficiency by using the diffraction efficiency in points across a lens diameter. They…

Post-buckling of a cantilever column: a more accurate linear analysis of a classical nonlinear problem
Beléndez Vázquez, Augusto - Hernández Prados, Antonio - Gallego Rico, Sergi - Ortuño Sánchez, Manuel - Neipp López, Cristian - Beléndez Vázquez, Tarsicio

Formato:	info:eu-repo/semantics/article
Enlaces:	A more accurate analytical approximate expression for the slope at any point of the elastic curve of a slender cantilever column is obtained by using a heuristic but pedagogical derivation. This derivation is based on the linearization of the nonlinear…

Cables under concentrated loads: a laboratory project for an engineering mechanics course
Beléndez Vázquez, Tarsicio - Neipp López, Cristian - Beléndez Vázquez, Augusto

Formato:	info:eu-repo/semantics/article
Enlaces:	Cables are one of the common structures studied in a first-year engineering mechanics course (statics), since the flexible cable is one of the usual methods of supporting loads. For example, the suspension bridge has been used for many centuries and…

Systematics and phylogeny of the tribe Paragini (Diptera: Syrphidae) based on molecular and morphological characters
Vujić, Ante - Ståhls, Gunilla - Rojo Velasco, Santos - Radenković, Snezana - Simić, Smiljka

Formato:	info:eu-repo/semantics/article
Enlaces:	We studied the phylogeny and systematics of the tribe Paragini (Diptera: Syrphidae) using morphological and molecular data. The paper presents separate parsimony analyses of both adult morphological characters and partial DNA sequence data from mitochondrial cytochrome c oxidase I and…
