Corrosion Behavior of Galvanized Steel Embedded in Concrete Exposed to Soil Type MH Contaminated With Chlorides por Baltazar Zamora, Miguel Ángel, Mendoza Rangel, José Manuel, Croche, René, Gaona Tiburcio, Citlalli, López, Luis, Olguín, Francisco, Almeraya Calderón, Facundo

“….% NaCl as aggressive agent by weight of soil, the exposure time was 260 days where, the results show that when the presence of NaCl in the soil was increased to 2 and 3% the levels of corrosion are from high to very high in all concretes, presenting a little better performance the concretes reinforced with galvanized steel and a small benefit could be identified or related to the properties of a denser and less impermeable matrix that presented the concrete mix made with cement CPC 30R RS.…”

Breeding biology of Eared Quetzals in the Sierra Madre Occidental, Mexico por González Rojas, José Ignacio, Cruz Nieto, Javier, Ruvalcaba Ortega, Irene, Cruz Nieto, Miguel A.

“…However, fewer potential predators, such as snakes and mammals, are present in the Sierra Madre than in tropical zones where most trogon species occur. In addition, antipredator behaviors, including nestlings with calls resembling a snake and nests with an unpleasant odor, may contribute to the high nesting success. …”

Cosmological perturbation theory in f(Q,T) gravity por Nájera, Antonio, Fajardo, Amanda

“…By considering an ansatz of f(Q, T) = f1(Q)+f2(T), which has been broadly studied in the literature and the coincident gauge where the connection vanishes, we got equations consistent with f(Q) gravity when fT = 0. …”
