Distribución de especies de plantas nativas y exóticas al lado de caminos a lo largo de un gradiente altitudinal en el noreste de México. por Sánchez Medrano, Fátima Zuleyma

“…Density data were collected and 13 environmental variables (% sand,% clay and% limo), percentage of stoniness, altitude, exposure, slope, percentage of bare soil, percentage of humus, pH, electrical conductivity and distance were evaluated to the road of each plot. The floristic composition of the sampling sites shows a diversity of 61 families, 163 genera, 178 native species and 17 correspond to exotic, having in this way an average of one exotic species at each sampling site. …”

Modelo de crecimiento de diámetro normal para Pinus durangensis en Durango, México. por Colín, José Guadalupe

“…The results showed that the independent distance indices presented slightly better results in the prediction of growth of normal diameter for Pinus durangensis, of which the two best indices of competition were used, ICi12 (derived from the radius between the basal area of the tree Objective and the basal area of the plot) and ICi6 (which represents the cup competition factor (CCF), to be analyzed in four base models. …”

Numerical study on the combustion process of a biogas spark-ignition engine por Carrera, José, Riesco, José, Martínez, Simón, Sánchez, Fausto, Gallegos, Armando

“…The combustion process of by biogas is characterized in terms tion of combustion, i. e., depending on the time elapsed while the reac- an of the dura tants (methane and oxygen) are transformed into products (mainly carbon dioxide and water). This study numerically evaluates the way in which the geometrical pa- rameters such as the compression ratio and operating parameters like engine speed, the excess air, the time of spark timing and carbon dioxide content of biogas affect the evolhution of the combustion process. …”

New Echinoid (Spatangoida: Toxasterinidae) from the Campanian of Coahuila, Northeastern Mexico por Silva Martínez, Luis Encarnación, Blanco Piñón, Alberto, De León González, Jesús Ángel, Rodríguez Vela, Hidalgo

“…The morphology of the specimens (test with a cordiform aboral region) as well as the sedimentary environment reported at the Austin Formation, suggests that this species represents an infaunal and detritivorous dweller living in a shallow water environment within the continental shelf. This is consistent with the more actual knowledge for other species of Diplodetus Keywords: Echinoids, Diplodetus, Upper Cretaceous, Campanian, Austin Formation, NE Mexico. …”

Synthesis, Characterization, and Biological Activity Studies of Copper(II) Mixed Compound with Histamine and Nalidixic Acid por Bivián Castro, Egla Yareth, López, Mercedes G., Pedraza Reyes, Mario, Bernès, Sylvain, Mendoza Díaz, Guillermo

“…The crystal structure of [Cu(hsm)(nal)H2O]Cl·3H2O (chn) showed a pentacoordinated cooper(II) in a square pyramidal geometry surrounded by two N atoms from hsm, two O atoms from the quinolone, and one apical water oxygen. Alteration of bacterial DNA structure and/or associated functions in vivo by [Cu(hsm)(nal)H2O]Cl·3H2O was demonstrated by the induction of a recA-lacZ fusion integrated at the amyE locus of a recombinant Bacillus subtilis strain. …”
