Recent rapid rise of a permethrin knock down resistance allele in Aedes aegypti in México por Kittayapong, Pattamaporn, Ponce García, Gustavo, Flores Suárez, Adriana Elizabeth, Fernández Salas, Ildefonso, Saavedra Rodríguez, Karla Lizet, Reyes Solis, Guadalupe del Carmen, Lozano Fuentes, Saúl, Guillermo Bond, J., Casas Martínez, Mauricio, Ramsey, Janine M., García Rejón, Julián Everardo, Domínguez Galera, Marco Antonio, Ranson, Hilary, Hemingway, Janet, Eisen, Lars, Black, William C.

“…For example within the city of Chetumal, Quintana Roo, Ile1,016 frequencies varied from 38.3%–88.3%. A linear regression analysis based on seven collections from 2007 revealed that the frequency of Ile1,016 homozygotes accurately predicted knockdown rate for mosquitoes exposed to permethrin in a bioassay (R2 = 0.98). …”

Estudio microfacial, mineralógico, geoquímico e isotópico de la formación San Felipe (Cretácico Superior), Noreste de México. por 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. …”

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 de la calidad del agua de tres ríos de la subcuenca del “Río Limón” en el estado de Nuevo León por 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 por 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. …”

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

“…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). …”
