    • CIELAB color paths during meat shelf life 

      Hernández Salueña, Begoña Upna; Sáenz Gamasa, Carlos Upna; Diñeiro Rubial, José Manuel Upna; Alberdi Odriozola, Coro Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      Meat color evolution from freshly cut to beyond shelf life, up to 40% of metmyoglobin, has been theoretically modeled using the Kubelka-Munk theory and a set of measured reference reflectance spectra of deoxymyoglobin, ...
    • Negative reflection, negative refraction and ray displacements in biaxial absorbing media, In4Se3 

      Alberdi Odriozola, Coro Upna; Diñeiro Rubial, José Manuel Upna; Hernández Salueña, Begoña Upna; Sáenz Gamasa, Carlos Upna (Taylor & Francis, 2019)   Artículo / Artikulua  OpenAccess
      We show the existence of negative reflection and negative refraction in a slab of biaxial absorbing medium In 4Se3 placed between two isotropic media. We find the limiting angle of incidence in the slab for these phenomena ...
