(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2009)The postembryonic development, consumption and life table parameters of Cydnodromus picanus Ragusa and Phytoseiulus persimilis (Athias-Henriot) were studied at 29.44 ± 1.47 °C and 42.35 ± 5.01% of RH with a photoperiod of ...
-
(Royal Society of Chemistry, 2017)Developing methods with a low environmental impact for nanoparticle synthesis remains one of the greatest challenges in nanotechnology. In this context, biomimetic and biological methods have emerged as green chemistry ...
-
(MDPI, 2020)Most of the biological impacts of Vitamin E, including the redox effects, have been raised from studies with alpha-tocopherol only, despite the fact that tocopherol-containing foods carry mixed tocopherol isomers. Here, ...
-
(2010)Undergraduate healthcare students are exposed to bloodborne pathogens, and data from developing countries is scarce. We report the experience of a comprehensive program dedicated to the management of this risk. The program ...
