Diseño y construcción de un reactor hibrido tipo batch para la producción de biocombustibles: biodiésel y bioetanol como caso de estudio. por Solís Ulloa, Juan Carlos

“…In order to scale this parameter to reactor level, the RMA varied from 3: 1 and 6: 1 (6 molecules of methanol per 1 of oil used) and the time of 15, 30, 45 and 60 minutes of process obtaining as a result that with a RMA of 6: 1 with a time of 60 minutes a conversion of 100 % was obtained, all these experiments were carried out at a temperature of 60 ◦ C and 400 rpm. …”

Evaluación y análisis de la expresión genética de Saccharomyces cerevisiae bajo condiciones de fermentación que afectan la floculación por Damas Buenrostro, Luis Cástulo

“…On the other hand, FLO genes content was variable (3 to 6 genes by strain), which impacted, at least in part, flocculation ability, being Lg-FLO1, FLO8 and FLO11 the most conserved. In real time PCR experiments, results showed that expression of FLO11 and Lg-FLO1 diminished when cells were exposed to catabolic repression. …”

Caracterización de los factores que influyen en el rendimiento y características de la canal de équidos. por Hernández Briano, Pedro

“…It is concluded that provenance, gender, age and weight at slaughter affect the carcass characteristics of the horses slaughtered in Mexico. In the third experiment, it was observed that the SP increased as the fattening days increased, in terms of GDP, this was higher in PE 21 and 42, decreasing in 63; CMS increased in PE 42 and 63; while the CA was more efficient in PE 21 and 42 with respect to 63. …”

Ecología y fisiología en las primeras fases de crecimiento de plantas suculentas en el sur del desierto chihuahuense en México y las montañas de Córdoba en Argentina. por Pérez Sánchez, Reyes Manuel

“…The objective of this second study was to evaluate the combined effect of water potentials and temperatures on seed germination and seedling characteristics in six species of globular cactus in the Córdoba Mountains: Echinopsis candicans, Gymnocalycium bruchii, G. capillaense, G. mostii, G. quehlianum y Parodia mammulosa. A factorial experiment was performed in which four levels of water potential (0, -0.2, -0.4 and -0.6 MPa) were combined with two temperature levels (25 y 32°C). …”
