    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

    Published 2005
    “…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

    Published 2005
    “…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. …”

    Valor nutricional de forrajes nativos del norte de México by Guerrero Cervantes, Maribel

    Published 2008
    “…The chemical composition was determined in each plant type; in addition, the extent and degree of ruminal fermentation, using the in vitro gas production technique with or whitout polietilene glycol and the in situ digestibility of dry matter, crude protein and neutral detergent fiber were also determined. Species varied in their contents (%DM) of ash (4.0-32), CP (3.9-18.6), NDF (18.7-65.1), ADF (10.6-42.3), lignin (1.1-14.5) and CT (0.1-9.1). …”

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

    Published 2017
    “…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. …”
