Here, we offer a detailed description of different novel techniques to obtain more precise erosion rates from highly accurate microtopographic data. Environment A Bending Test for Determining the Atterberg Plastic Limit in Soils José Manuel Moreno-Maroto1, Jacinto Alonso-Azcárate1 1Department of Physical Chemistry, Faculty of Environmental Sciences and Biochemistry, University of Castilla-La Mancha The traditional standardized test for determining the plastic limit in soils is performed by hand, and the result varies depending on the operator. An alternative method based on bending measurements is presented in this study. This allows the plastic limit to be obtained with a clear and objective criterion. Immunology and Infection RNA Interference in Ticks Katherine M. Kocan1, Edmour Blouin1, José de la Fuente1,2 1Department of Veterinary Pathobiology, Center for Veterinary Health Sciences, Oklahoma State University, 2(CSIC-UCLM-JCCM), Instituto de Investigación en Recursos Cinegéticos IREC A method for RNA interference (RNAi) by injection of dsRNA into unfed ticks is described. RNAi is the most widely used gene-silencing technique in ticks where the use of other methods of genetic manipulation has been limited.
