چکیده
We present a study of electromagnetic attenuation over different environments of Mexico City, for an empirical modification of Free Space Attenuation (FSA). Our work uses results of in-site measurements in different places in the city. We intend to measure attenuation in different places to compare and validate modification of FSA. Even we are working in different communications standards, we present results for WiMAX at 3.5 GHz. Resumen. Presentamos en este trabajo un estudio de atenuación en propagación electromagnética en diferentes escenarios en la ciudad de México, para una modificación empírica de la Atenuación del Espacio Libre (AEL). Nuestro trabajo usa resultados de medición en diferentes lugares de la ciudad. La intención es comparar con las mediciones de atenuación para comparar y validar la modificación de AEL. Aunque hemos hecho el experimento para diferentes estándares de comunicaciones, presentamos en este trabajo los resultados para WiMAX en 3.5 GHz.

A Policy Analysis on the Proactive Prevention of Chronic Disease: Learnings from the Initial Implementation of Integrated Measurement for Early Detection (MIDO)
Mexico, like many low- and middle-income countries (LMICs), faces an epidemic of chronic non-communicable diseases (NCDs), specifically diabetes, hypertension, obesity, and lipid disorders. Many people with these NCDs may not be aware that they have a disease, pointing to the need for broader screening programs. The traditional prevention policy in Mexico was based on screening with a paper-bas...
متن کاملBrain multi-infarct and decompression sickness
Scuba diving is associated with an important risk of developing decompression sickness secondary to formation of gas bubbles inside the body. The latter is formed mainly by nitrogen in the body on the diver’s way to the surface (1,2). In some cases, it might injure the central nervous system. Several decompression cases that have been associated with neurologic symptoms are described in the l...

In the hen oviduct, tubules have been identified that preserve the sperm, maintaining viability for up to 15 weeks. This study aimed to evaluate the physiological status of rooster sperm when preserved in vitro with uterus vaginal junction secretions (UVJS). Males and females of the Rhode Island breed were used. Sperm aliquots were prepared using Lake extender and Lake extender with UV...
متن کاملHealth Risk Assessment of Heavy Metals: Cu, Cd, Pb, Ni and Hg, in Catfish Ariopsis Felis in Southern Mexico
Background: Metal pollution is a problem in many parts of the world. These metals can be harmful when they exceed the recommended limits. By analyzing metal concentrations in living organisms, it is possible to deduce the bioavailability and the level of environmental contamination for specific metals in an ecosystem. The aim of this study was to determine the heavy metals copper, cadmium, lead...
