Is the frictional force always opposed to the motion? Authors: Agustín Sánchez-Lavega,M A Arriandiaga,Agustín Salazar A common idea is that frictional force is always opposed to motion. With the aid of two examples the authors show how, in some cases, the frictional force acts in the same direction as the centre of mass velocity of the body accelerating it. IOP Publishing	1990-03-01
On the (generalized) Korteweg-de Vries equation Authors: Kenig, Carlos E.,Ponce, Gustavo,Vega, Luis Duke University Press	1989-12-01
Theory of thermal diffusivity determination by the ‘‘mirage’’ technique in solids Authors: Agustín Salazar,J. Fernández,Agustín Sánchez-Lavega A complete theoretical treatment of the ‘‘mirage’’ (optical beam deflection) technique has been performed for thermal diffusivity measurements in solids. Numerical calculations of the transverse deflection show there is a linear relation between the first noncentral zeros of the real part of this… AIP Publishing	1989-06-01
A survey of Saturn's Northern Hemisphere from 1979 to 1987 Authors: Agustín Sánchez-Lavega,J.A. Quesada Abstract A photographic survey in four spectral regions (ultraviolet, blue, visible and red) of the Northern Hemisphere of Saturn's atmosphere, has been carried out between 1980 (epoch of the edgewise apparition of the rings) and 1987 (ring's maximum aperture), with the aim of analyzing the… Elsevier BV	1988-12-01
Ground-based imaging of Jovian cloud morphologies and motions Authors: J.A. Quesada,Agustín Sánchez-Lavega Abstract Telescopic photographs of Jupiter obtained during one Jovian year (1975–1985) have been analyzed in order to study the morphology and motions of the great-scale cloud systems present in the northern hemisphere during the epoch pre- and post-Voyager flyby spacecraft mission (see Sanchez-… Elsevier BV	1988-12-01
