Effect of mineral aggregates and chemical admixtures as internal curing agents on the mechanical properties and durability of highperformance concrete by Vázquez Rodríguez, Francisco Javier, Elizondo Villarreal, Nora, Hypatia Verástegui, Luz, Arato Tovar, Ana María, López Perales, Jesús Fernando, Contreras de León, José Eulalio, Gómez Rodríguez, Cristian, Fernández González, Daniel, Verdeja, Luis Felipe, García Quiñonez, Linda Viviana, Rodríguez Castellanos, Edén Amaral

“…The effectiveness of internal curing to develop higher strength is attributed to control in the porosity and a high water release at a later age. Finally, the lowest permeability value at 90 days (945 C) was found by the substitutions of fine aggregate by 20% of pumice stone saturated with shrinkage reducing admixture into pores and OPC40C by 15% of pulverized fly ash. …”

Pérdidas por intercepción en cuatro especies del matorral en Linares, N. L. by Tamez Ponce, Cuauhtemoc

“…Linear regression analyzes between gross precipitation and interception loss for four species, showed values of 14, 16, 21 and 25% for Leucaena leucocephala, Casemiroa greggii, Acacia farnesiana, and Condalia hookeri, respectively, being these key species when making management decisions on the water yield in a basin, rejecting this hypothesis and concluding that people by interception differ among the evaluated species.…”

Estudio geofísico para la determinación de la estructura geológica en los alrededores del baño San Ignacio, Linares, Nuevo León by Pérez Aguirre, Xavier Jednnin

“…To 30 Km from Linares City, Nuevo León, is located Baño San Ignacio spring wich its average temperature (36°C) is higher than other water resources in the area. In previusly works the origin of this thermal anomaly was related to two different geologic structures placed under the spring: 1) an alkaline intrusive body linked to a Sierra of San Carlos volcanic complex who belong to Eastern Alkaline Province and, 2) a salt diapir. …”

Effect of moringa leaf powder and agave inulin on performance, intestinal morphology, and meat yield of broiler chickens by Moreno Mendoza, Yaritza, López Villarreal, Karla Denisse, Hernández Martínez, Carlos Alberto, Rodríguez Tovar, Luis Edgar., Hernández Coronado, Ana Cecilia, Soto Domínguez, Adolfo, Hume, Michael E., Méndez Zamora, Gerardo

“…The results showed that analysis of treatments at time were not different (P . 0.05) for broiler weights, feed and water intake, and weight gain. Treatment was significant (P , 0.05) for feed efficiency at 22 to 40 d; the T4 group presented higher (P , 0.05) values, and the T1 group presented lower (P , 0.05) values. …”
