En el marco de la pandemia covid-19, arte se convirtió en uno sus interpretantes más vigorosos, ejerciendo toda una pedagogía para transformar contacto inmediato mediatizado. Nuestro corpus conforma por tres conjuntos imemes que giran torno a del covid-19 y apoyan imágenes macro provenientes las artes plásticas. Se tratará analizar, desde perspectiva peirceana, sociosemiótica operacional (Trave...

This work aimed to prepare a nanoemulsion preparation containing budesonide and assess its aerodynamic behavior in comparison with suspension of budesonide. In-vitro aerodynamic performance of the corresponding micellar solution (ie. nanoemulsion preparation without oil) was investigated too. Nanoemulsions of almond oil containing budesonide, as a hydrophobic model drug molecule, were prepared ...

Aeroelastic instabilities are an important factor in the design of modern high-speed, flexible aircraft. The current trend is toward the creative use of composites to delay these instabilities. To obtain an optimum design, an accurate as well as efficient model is required. As a first step towards this goal, aeroelastic analysis is carried out for a swept composite box beam, using a linear stru...

In 1957 the slender-delta type of configuration had been adopted in the U.K. as the most promising for a supersonic transport aircraft designed to cruise at about M = 2.0, and by 1959 one or two exploratory studies of the aeroelastic behaviour of such layouts had been made. Professor Etkin now suggested a mode of attack on the steady and quasi-steady aeroelastic problems, whereby such an aircra...

Consider a linear diierential equation of some order n with coef-cients analytic in the unit disk. Assuming that the equation has a unique Fuchsian singular point at z = 0, and all roots of the corresponding indicial equation are real, we establsih an upper bound for the number of zeros of any solution of this equation in any sector with the vertex at z = 0. This upper bound is in some sense li...

Optimal aerodynamic shape design aims at finding the minimum of a functional by controlling the PDE modeling the flow using surface deformation techniques. As a solution to the enormous computational resources required for classical shape optimization of functionals of aerodynamic interest, probably the best strategy is to use in a systematic way, methods inspired in control theory. One of the ...
