, 2022 Durante décadas se ha estudiado el comportamiento del asfalto ante procesos de envejecimiento, debido a su importancia en la industria de la construcción de pavimentos. El asfalto al envejecerse tiende a rigidizarse y ser más susceptible a la falla, no obstante, se ha observado una recuperación de la rigidización del asfalto ante ciertos rangos de ...

Human eyes do not need monochromatic aberrations for dynamic accommodation
Ophthalmic and Physiological Optics, Volume 37, Issue 5, Page 602-609, September 2017., 2017 Abstract Purpose To determine if human accommodation uses the eye's own monochromatic aberrations to track dynamic accommodative stimuli. Methods Wavefront aberrations were measured while subjects monocularly viewed a monochromatic Maltese cross moving sinusoidally around 2D of accommodative demand with 1D amplitude at 0.2 Hz.

The Role of Propolis in Oxidative Stress and Lipid Metabolism: A Randomized Controlled Trial
Evidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017 Although there is evidence of the benefits of propolis on human health, the vast majority of studies have been conducted using animal models. The present study includes the chemical characterization and clinical evaluation of the effects of the oral administration of propolis solution on the oxidative status and modulation of lipids in a human ...
