Published: April 2019

BACKGROUND:
Unintentional suffocation is the leading cause of injury death among infants &lt;1 year old in the United States, with 82% being attributable to accidental suffocation and strangulation in bed. Understanding the circumstances surrounding these deaths may inform prevention strategies.

METHODS:
We analyzed data from the population-based Sudden Unexpected Infant Death Case Registry from 2011 to 2014. Cases categorized as explained suffocation with unsafe sleep factors (suffocation), per the Centers for Disease Control and Prevention’s Sudden Unexpected Infant Death Case Registry classification system, were included and assigned a mechanism of obstruction, including soft bedding, overlay, or wedging. We calculated frequencies and percentages of suffocation deaths by mechanism and selected demographic and sleep-environment characteristics.

RESULTS:
Fourteen percent of sudden unexpected infant death cases were classified as suffocation; these cases were most frequently attributed to soft bedding (69%), followed by overlay (19%) and wedging (12%). Median age at death in months varied by mechanism: 3 for soft bedding, 2 for overlay, and 6 for wedging. Soft-bedding deaths occurred most often in an adult bed (49%), in a prone position (82%), and with a blanket (or blankets) obstructing the airway (34%). Overlay deaths occurred most often in an adult bed (71%), and infants were overlaid by the mother (47%). Wedging deaths occurred most often when the infant became entrapped between a mattress and a wall (48%).

CONCLUSIONS:
Safe sleep environments can reduce infant suffocation deaths. Increased knowledge about the characteristics of suffocation deaths can help inform prevention strategies by targeting highest-risk groups.

The chemical composition of a freshwater surface depends on the sources of input that can be of natural or anthropogenic origin. This study examined the spatial variability of the water quality from Chapala Lake and discussed the possible sources to this freshwater surface which is the largest rift lake in Mexico. The methodology included multivariate statistical techniques to analyze the possible relationship between water quality and the natural and anthropogenic factors of the area. The outcome showed the existence of four groups of water mixture in the lake. Each one showed two or three end members that characterized its chemical nature. The different groups showed a spatial distribution and a particular spectral behavior was detected from the analysis of a Landsat 7 ETM+ image. The spectral signatures extracted from the satellite image showed a high reflectivity in the range of 830 - 1300 nm for the water provided by the Lerma-Chapala (group IV) system, which represents the most polluted water in the lake. This spectral behavior is not present in the rest of the group. The Western portion of the lake is fed mainly by open water. Contributions from groundwater dominate the Central part, and in the Eastern region, the primary source is the contaminated water from the Lerma river system. A high hydraulic head (hydraulic barrier) prevents the highest level of pollution from the Lerma river. This hydraulic barrier constituted by a significant portion of groundwater is at the Central part of the lake. Furthermore, the most polluted water flows directly to the Metropolitan Region of Guadalajara through the Santiago river. The predominant role played by the groundwater in the dynamics of Chapala Lake is explained, in part, from its tectonic origin. The dynamics of water in the Chapala Lake suggest the need to implement some management plans considering the tectonic origin of the Lake as an advantage for the control of pollution because of the significant contribution of groundwater in the Chapala Lake freshwater system.

Published: April 2019

A pesar de no siempre tener un papel protagónico, la masonería ha aparecido muchas veces en la pantalla grande. En ocasiones la vemos en forma de cameo, otras como un easter egg, pero Hollywood ha capitalizado el interés y el morbo que genera en el público esta organización con el fin de construir mejor a sus personajes o de complementar las historias narradas en sus filmes. En este vertiginoso periplo descubriremos algunas de las representaciones de la masonería y masones que han aparecido en el cine, además de los motivos –abiertos u ocultos– que justifican su presencia en la pantalla.

Mangroves of Colombia revisited in an era of open data, global changes, and socio-political transition: Homage to Heliodoro Sánchez-Páez
Authors: Blanco-Libreros Juan F. , Álvarez-León Ricardo 
Published: April 2019

Colombia es el único país suramericano con costas tanto en el Océano Pacífico como el Mar Caribe, por lo cual exhibe grandes contrastes para los manglares en términos de tipos de climas y geoformas costeras. Por ejemplo, los manglares son extensos a lo largo de la costa del Pacífico debido a la alta precipitación anual y a la presencia de grandes deltas. Estos manglares son el hábitat de la única especie endémica del Neotrópico (Pelliciera rhizophorae), también clasificada como amenazada. En contraste, los manglares se distribuyen de forma discontinua a lo largo de la costa Caribe, siendo extensos en los tres deltas más grandes y en unas pocas lagunas costeras. Además, los manglares enanos y de baja estatura están presentes en las zonas áridas de la costa norte, bañadas por quebradas y ríos estacionales. En estudios recientes se resalta la importancia global de los manglares de Colombia en términos de su extensión, sus bajas tasas de deforestación (particularmente en la costa Pacífica) y sus grandes reservas de carbono. Sin embargo, la mayor parte de lo que actualmente sabemos de la biogeografía de los manglares colombianos se ha obtenido a partir del análisis de estudios independientes llevados a cabo en diferentes sitios y años. La voluminosa información recolectada por Heliodoro Sánchez-Páez y sus colaboradores en el mayor inventario nacional de manglares (PMC: Proyecto Manglares de Colombia, Ministerio del Medio Ambiente) recopilado a mediados de la década de 1990, ofrece una oportunidad para, en combinación con datos abiertos, revisar hipótesis biogeográficas (por ejemplo, que la alta precipitación promueve el valor de importancia del mangle rojo) y explorar patrones macroecológicos. En homenaje a Heliodoro Sánchez-Páez (fallecido en el 2017), se presenta a la comunidad la base de datos HELIO_SP.CO v.1, derivada de este inventario forestal, como una plataforma para los estudios macroecológicos y línea de base para futuras evaluaciones del impacto del cambio climático y en los usod de la tierra. Se revisaron las contribuciones del PMC y se exploraron patrones geográficos generales utilizando la base de datos HELIO_SP.CO v.1. En este sentido, se describió el recambio de las dos especies dominantes a lo largo del gradiente de precipitación observado desde Nariño hasta La Guajira. Se utilizaron datos rasterizados de WorldClim 2 para explorar los espacios de precipitación y temperatura donde las especies fueron registradas. Por último, se revisó brevemente el progreso de las “ciencias del manglar” desde 1997 y se detectaron algunos de los desafíos relacionados con el cambio climático y las situaciones posteriores al acuerdo de paz en Colombia. © 2019.

Authors: Sadeghi Afsaneh , Mehrafshan Fatemeh , Beheshti Mohammad Hosein 
Published: April 2019

Background: Exposure to noise is an important safety and health problem in many industries. The rail transport industry is one of the industries involved with this problem due to the variety of equipment and its scope. The present study aimed to evaluate noise pollution and determine the sources of noise at Mashhad railway station. Methods: In this descriptive-analytic study in 2014, the departments with noise pollution were identified and studied based on an initial assessment of all parts of the railway station. Noise was measured in ten departments and units. The environmental and local noise was measured by calibrated sound level meter Model CEL485 in A and C networks according to ISO9612 and ISO 11200 standards. Then the collected data entered and analyzed in Surfer V.10 and Excel software. Results: The results of noise measurement showed that the average sound pressure level in units of Diesel GM, repair shop, refueling station, Diesel Siemens, and platform 3 was in hazard range. The results of measurement of the average sound pressure level in departments and units and the isosonic mappings drawn by Surfer V.10 software as well as the results of the average noise level in GM diesel showed that GM diesel (with LP=87.60 dB (A)) is the main source of noise at Mashhad railway station. The results of this study showed that diesel engines, gearboxes, moving trains, and beeps are the main noise generator components in GM diesel. The highest mean sound pressure level among these components was related to the diesel engine with an average sound pressure level of 87.60 dB (A). In general, the average sound pressure level of this diesel was 95.45 dB in the dominant frequency of 63 Hz. Conclusion: Based on the result of this study, GM diesel plays a major role in transporting at Mashhad railway station, accordingly the design and implementation of technical control measures such as chamber and enclosure of noise generator components are essential to reduce the average sound pressure level.

La habichuela larga se cultiva en el sistema de producción de economía campesina. El objetivo del trabajo fue obtener información básica sobre la producción y los retornos económicos de la habichuela larga en el Caribe Húmedo de Colombia en el año 2018. No se evidencian trabajos anteriores en materia de caracterización tecnológica y socioeconómica. La información se obtuvo de una encuesta estructurada aplicada mediante el método de muestreo aleatorio simple a 16 productores de habichuela larga. Los retornos económicos se calcularon empleando patrones de costos y técnicas de análisis económico de rentabilidad. Los resultados demuestran que los productores tienen experiencia en cultivar la habichuela larga de tres a cuarenta años, bajo un sistema de agricultura familiar y de subsistencia; la superficie dedicada al cultivo varía de 0,2 a 0,5 ha. Predomina el uso de mano de obra familiar en un 75 %, el 100 % de los agricultores usa semilla no certificada, un 90 % realiza control manual de malezas y el 70 % hace control químico de insectos. Un 86 % de la producción tiene como destino el mercado local, y un 14 %, el consumo de las familias. Los costos de producción corresponden a $3.476.914,2 por hectárea, la producción media es de 4.950 kg ha-1, el precio de venta promedio es de $765 por kilogramo, lo cual genera una relación beneficio costo de 1,09 en cuatro meses del ciclo productivo y una rentabilidad de 8,9 %. Dado que las inversiones son bajas, se considera una producción eficiente, que garantiza la sostenibilidad en el tiempo.
