    Effect of cattle and wildlife exclusion areas on the survival and growth of Pinus culminicola Andresen & Beaman por Jiménez Pérez, Javier, Yerena Yamallel, José Israel, Alanís Rodríguez, Eduardo, Aguirre Calderón, Oscar Alberto, Martínez Barrón, René Alejandro

    Publicado 2018
    “…The results show diferences between 2000 and 2014 in survival rate and diameter and height growth in the three exclusion areas; E1 and E2 recorded higher averages. The main causes of mortality in this species are attributed to extreme weather conditions and the damage caused by cattle and small mammals…”

    Mindlin-Reissner Analytical Model with Curvature for Tunnel Ventilation Shafts Analysis por Alvarez Pérez, José, Peña, Fernando

    Publicado 2021
    “…Based on the Mindlin–Reissner theory for thick shells, this model also takes into account the shell constitutive curvature and considers an expression of the shear correction factor variable (αn) in terms of the thickness (h) and the radius of curvature (R). The main advantage of the proposed model is that it has the possibility to analyze thin, medium and thick tunnel ventilation shafts. …”
