A population-based, cross-sectional study using a standardized questionnaire administered to a random sample of 2087 schoolchildren 6-7 years of age (1078 girls and 1009 boys) living in the city of Mexicali, Baja California, Mexico. To assess the prevalence of allergic rhinitis symptoms among schoolchildren in Mexicali, Baja California, Mexico, and determine what impact a rural environment might have on this condition. īäcker, Claudia Barraza-Villarreal, Albino Moreno-MacÃas, Hortensia Escamilla-Núñez, Consuelo Romieu, Isabelle On the eastern side of the El Mayor Mountain we ![]() The preliminary interpretation using the "reverse shot" indicates a crust of 15 km depth beneath the Mexicali Valley and 19 km under the El Mayor Mountain and Laguna Salada basin. Velocities of our model for the region under study are about 1 km/s higher than the model proposed by McMechan and Mooney (1984) for the Imperial Valley. We propose an average-three-layer velocity structure model: 2.9, 5.6 and 6.9 km/s, with thicknesses of 1.2, 4.4 and 9.6 km, respectively. Method based on asymptotic ray theory programed in the RAYINVR software (Zelt and Smith, 1992). From the first arrivals of refractions and reflections of the P wave we performed direct modeling of travel times and relative amplitudes (normalized synthetic seismograms). The arrival Pn wave is observed at three stations located in Laguna Salada and Sierra Juarez. Record sections show seismograms with impulsive P arrivals for nearby stations. As a "reverse shot", for a 47 km section between SLRC and El Mayor Mountain, we used an aftershock M 3.4 of the 2010 M 7.2 El Mayor - Cucapah earthquake. The beginning of the profile is at San Luis Rio Colorado (SLRC), Sonora and its ending is at the middle of Sierra Juarez, Baja California. Records gathered were used to estimate a crust velocity structure model for South Mexicali Valley. The stations, spaced 6 km along a refraction profile, recorded a blast performed in the southwest Arizona near the border with Sonora, Mexico. We installed 16 three-component short period stations (2 Hz) and one broadband station (100 s - 50 Hz). Due to the lack of an appropriate crust model for South Mexicali Valley, a refraction study was conducted. The northern Baja California region consists of two subregions of different geological features: the Peninsular Ranges of Baja California, of granitic composition, and the Mexicali Valley region, characterized by a series of sedimentary basins: the Laguna Salada and the Mexicali Valley. We provide an independent source of truth in mobile network experience: A data source that shows how users experience mobile network speeds worldwide.A Crustal Velocity Model for South Mexicali Valley, Baja California, México. See a timeline of your speed tests in the history tab and review the stats for each test to monitor how your network experience has changed over time. View all of your speed tests by location on a map in the Dashboard and sort them by best and worst performance. Then, simply choose the apps you use most to see how they are impacted by your current network connection - no more trying to work out if your 3G, 4G/LTE & 5G internet speed is good or not! One simple speed test gives you easy-to-understand results on download speed and upload speed (in Mbps) and the ping time performance (in milliseconds). Meteor’s download speed, upload speed and ping tests give you complete clarity on how your mobile connection is impacting video streaming services such as Netflix and YouTube, music streaming services like Spotify and mobile games such as Clash Royale and Pokemon Go.
