(Editorial Eunk, 2024-06)Los alimentos azucarados son muy sensibles al calor y pueden deteriorarse durante el almacenamiento. El hidroximetilfurfural (HMF) es un compuesto formado por la deshidratación de la fructosa, su presencia en la miel se ... -
Effect of deforestation and introduction of exotic grasses as livestock forage on the population dynamics of the cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) in northern Argentina
(2013-12)The effect of deforestation and the introduction of exotic grasses on the population dynamics of Rhipicephalus (Boophilus) microplus in northern Argentina was analysed. Biological parameters that were measured included ... -
Effect of different mini‐volume colloid centrifugation configurations on flow cytometrically sorted sperm recovery efficiency and quality using a computer‐assisted semen analyzer
(Wiley, 2018-02)Straws of sex‐sorted sperm are usually packaged at a low concentration (e.g., ~2.1 × 106 sperm/ml) and cost significantly more than unsorted conventional semen from the same sire. In order to maximize the efficiency of ... -
