Rational Design, Synthesis and Evaluation of CD-Containing as a Prednisone Delivery Platform
(Facultad de Ciencias, 2018)This study describes the in-silico rational design, synthesis and evaluation of cross-linked polyvinyl alcohol hydrogels containing γ-cyclodextrin (γ-CDHSAs) as platforms for the sustained release of prednisone (PDN). ... -
Rational Development of a Novel Hydrogel as a pH-Sensitive Controlled Release System for Nifedipine
(MDPI, 2018)This work depicts the rational development (in-silico design, synthesis, characterization and in-vitro evaluation) of polyvinyl alcohol hydrogels (PVAH) cross-linked with maleic acid (MA) and linked to gamma-cyclodextrin ... -
Real Structures on Marked Schottky Space
(Facultad de Ciencias, 2018)Marked Schottky space M S g is an explicit model of the quasiconformal deformation space of a Schottky group of rank g , this being isomorphic to the punctured unit disc for g = 1 and, for g ⩾ 2 , a connected complex ... -
Real time optical flow estimation for images with large displacements
(2016 IEEE International Conference on Automatica (ICA-ACCA), 2016)Optical flow is defined as the pattern of apparent motion of objects in a image sequence. Optical flow has many applications: control of automatic taking off and landing of an autonomous aircraft, video compression, noise ... -
