Estudio microfacial, mineralógico, geoquímico e isotópico de la formación San Felipe (Cretácico Superior), Noreste de México. by Tienda Garza, Jaime Antonio

“…ABSTRACT The San Felipe Formation (total thickness ~130 m, Santonian - Campanian) is a lithological unit, included in the stratigraphic column of the Sierra Madre Oriental, Northeastern Mexico, consisting of packstone-wackestone varying to mudstone carbonate from light to dark gray (thickness 20-100 cm), constituted by calcite, quartz and illite with characteristical Upper Cretaceous planktonic foraminifera, radiolarians and calcispheres, which was paulatined transformed in shale (thickness <5 cm) with the stratigraphic rise, constituted by calcite, quartz, albite, and illite. …”

Estimación del contenido de carbono total de especies arbóreas y arbustivas en áreas con diferente uso histórico, en una fracción del matorral espinoso tamaulipeco, Linares, N. L.... by Yerena Yamallel, José Israel

“…By a completely randomized ANOVA there were not any differences found in the average of total carbon content of the species (Pr < 0.0564), this content varied from 44.25 to 47.08% with an general average of 45.52%; Cordia boissieri (44.25 ± 1.52%) and Acacia farnesiana (44.52 ± 1.37%) in the site of Traditional Agriculture those were the species that were with the smallest values, Forestiera angustifolia (47.08 ± 1.27%) with highest in the site of Extensive Foraging. …”

Evaluación de la calidad del agua de tres ríos de la subcuenca del “Río Limón” en el estado de Nuevo León by Ríos Saucedo, Julio César

“…However none chamical constituent exceeded set standards but concentrations of several constituents (pH, CE, Ca2+, Mg2+ Na1 + CO3 - HCO3 Cl- , SO42-) varied according to time, river and location. The time source of variation was explained by increased discharge which appeared to control the concentration of several chemical constituents by dilution. …”

Evaluación del contenido de carbono en bosques del sur de Nuevo León by Domínguez Cabrera, Gabriel

“…Therefore, the main objective was to evaluate forest capacity for carbon sequestration at the South of Nuevo León, in order to test that this capacity varies among forest types. To do so, from 8 to 12 trees belonging to Pinus teocote, Pinus pseudostrobus and Quercus spp., were felled to obtain total dry weight and to adjust diameter equations for diameters above 1.3 m. …”

Aislamiento y selección de cepas mutantes de Hirsutella citriformis inducidas por el agente químico: metanosulfonato de etilo (EMS). by Cruz Juárez, Georgina

“…Techniques such as biphasic culture on different low-cost substrates (sorghum, rice and oats) were evaluated to obtain the highest conidia production that would be used in classical mutagenesis with the chemical agent ethyl methane sulfonate (EMS) which has been successfully used to introduce changes of a single base in the DNA, a mutation protocol was established varying times and concentrations for the obtaining of mutant strains, which were characterized based on radial growth, production of conidia and speed of germination in media as PDA and PDA with yeast extract. …”
