Mexico is a seismically active country. Earthquakes with magnitudes larger than 7.0 happen, on average, every other year. This fact requires a rapid and consistent response from the national monitoring agency, the Servicio Sismológico Nacional, SSN (Mexican National Seismological Service). For this purpose, in 2014, the SSN created a set of procedu...

The SISMOMex project represents more than 110 yr of seismological information from Mexico. Its objective is the preservation, search, recovery, systematization, reuse, and dissemination of data and information from the seismograms generated by the Servicio Sismológico Nacional (SSN, National Seismological Service of Mexico) and published material a...

Xyoli Pérez-Campos et al. report on the Servicio Sismológico Nacional in Mexico for the Summary of the Bulletin of the ISC.

The Servicio Sismológico Nacional (SSN, Mexican National Seismological Service) has a history of 107 yrs. In the last 13 yrs, the SSN has gone through a significant modernization process, involving the installation of new broadband stations with colocalized accelerometers, seismometers, and Global Positioning System (GPS) receivers. New collaborati...

This study compares the total suspended sediment (TSS), total dissolved solids (TDS), and dissolved organic carbon (DOC) dynamics of two major inter-tropical rivers, the Congo in Central Africa and the Orinoco in South America, focusing on sampling undertaken during the period 2006–2010. Both rivers are characterized by similar mean annual discharg...

La predominancia de un mosaico de los biomas sabana y bosque en los espacios del sector oriental del Parque Nacional Canaima – PNC en Venezuela, conocido como La Gran Sabana ha sido reportada por numerosos autores. Ellos coinciden en que el fuego ha constituido el factor determinante en la regulación de la superficie de estos dos biomas. Además, la...

El Servicio Sismológico Nacional del Instituto de Geofísica de la Universidad Nacional Autónoma de México y la Organización del Tratado para la Prohibición Completa de Ensayos Nucleares instalaron conjuntamente una red sísmica e hidroacústica en Isla Socorro. En el presente estudio se reporta la detección de diez sismos, ocurridos en junio y julio...

The use of percutaneously inserted central catheters (PICCs) is an established practice in most NICUs. With the widespread use of these catheters, an increasing number of PICC complications has been reported in neonates. We present one case of a PICC retained and tethered in the vein in a very low birth weight infant, as well as a systematic review...

This paper provides a statistical characterization of the traffic in a fiber network for voice and data transmission. This research operates with real data from more than 33,000 users. The most significant applications (ftp, http, p2p services,…) have been processed. Also, a model of the traffic generated is implemented, representing the usage that...

Familial 22q11.2 deletions have been reported as a 6%-28% of the total affected cases of 22q11.2 microdeletion syndrome (del22q11.2). Different deletion genotypes have been described for this disorder, with a predominant 3 Mb deletion present in 90% of the cases, a less common 1.5-2 Mb deletion in 8%, and atypical smaller deletions in 2%. We have s...

Intussusception is an extremely rare disorder in preterm infants and it is often misdiagnosed as necrotizing enterocolitis. We report a case of intussusception in a 30-day-old preterm infant of 26 weeks of gestational age and a birthweight of 610 g who was diagnosed via abdominal ultra sonography. A systematic review of the literature was performed...

We conducted a controlled, randomized trial to study the effect of minimal enteral feeding on leucine uptake by splanchnic tissues, as an indicator of maturation of these tissues, in preterm infants in the first week of life. Within a few hours after birth, while receiving only glucose, a primed constant infusion of [1-(13)C]-leucine was started an...
