In this work, we have successfully synthesized a set of titania photocatalytic nanocomposites by the
incorporation of different TiO2 content on wheat bran residues. The obtained catalysts were characterized
by different techniques including UVeVis spectroscopy, X-ray diffraction (XRD), X-ray photoelectron
spectroscopy (XPS) and Transmission Electron Microscopy (TEM) while their photocatalytic activity was
investigated in the oxidation of benzyl alcohol under UV light irradiation. Benzaldehyde yields were ca.
20%, with conversion in the systems of ca. 33% of benzyl alcohol by using 10%Ti-Bran catalyst, as
compared to 33% yield to the target product (quantitative conversion of benzyl alcohol) using commercial
pure TiO2 (P-25). The photocatalytic activity results indicate...

Background: American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of
colonization and settlement, through different migration routes, andmay have also suffered the influence of cattle directly imported
from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the
survival of Creole populations, some of which have nearly disappeared or were admixed with exotic breeds. Assessment of the
genetic status of Creole cattle is essential for the establishment of conservation programs of these historical resources.
Methodology/Principal Findings: We sampled 27 Creole populations, 39 Iberian, 9 European and 6...
