The L1014F mutation in the voltage-sodium channel gene has been associated with resistance to DDT and pyrethroids in various arthropod species including mosquitoes. We determined the frequency of the L1014F kdr mutation in 16 field populations of Culex quinquefasciatus from Northeastern mexico collected between 2008 and 2013. The L1014F was present in all populations analyzed with the lowest frequency （3.33%） corresponding to the population from monclova collected in 2012, and the highest frequency （63.63%） from the monterrey population collected in 2012. The presence of a kdr mutation in populations of Cx. quinquefasciatus from northeastern mexico provides evidence ofpyrethroid resistance. This requires a special attention, considering that pyrethroid-based insecticides are commonly used in vector-control campaigns, especially against Aedes aegypti （L.）.

The multilayered structure of the European airport network（EAN）,composed of connections and flights between European cities,is analyzed through the k-core decomposition of the connections *** decomposition allows to identify the core,bridge and periphery layers of the *** core layer includes the best-connected cities,which include important business air traffic *** periphery layer includes cities with lesser connections,which serve low populated areas where air travel is an economic *** remaining cities form the bridge of the EAN,including important leisure travel origins and *** multilayered structure of the EAN affects network robustness,as the EAN is more robust to isolation of nodes of the core,than to the isolation of a combination of core and bridge nodes.

This work studies the influence of a commercial dispersion of multi wall carbon nanotubes （mWCNT） on the hydration of a class G cement paste, at room and elevated down-hole temperatures. The mWCNT dispersion was produced with a solids concentration of 3.0 % by mass and an anionic surfactant as dispersing agent. Cement pastes with water-to-cement ratio of 0.45 and additions of solid mWCNT by mass of cement up to 0.50 % were studied. Isothermal calorimetry results showed a clear retardation of the hydration of cement caused by the surfactant contained in the mWCNT dispersion. Nevertheless, thermogravimetric evaluations showed that once the hydration reaction resumed, the retardation effect of the surfactant did not have a negative impact on the amount of hydration products precipitated. It was concluded that the commercial mWCNT dispersion presents a good potential to be applied in oil well cement pastes.

The main aim of this paper is to study whether the Gromov hyperbolicity is preserved under some transformations on Riemann surfaces （with their Poincare metrics）. We prove that quasiconformal maps between Riemann surfaces preserve hyperbolicity; however, we also show that arbitrary twists along simple closed geodesics do not preserve it, in general.
