E-Solidarity and Exchange

Abstract

Between October 24 and 25 in 2015, Mexico faced the strongest hurricane ever registered in the Western Hemisphere, which reached a record of 200 mph (325 km/h) of maximum sustained winds. In spite of pessimist predictions about the final outcome of this natural disaster, at the end, it degraded itself into a tropical storm when landing in the Mexican state of Jalisco. The present research stands in a data collecting process from social media during two moments: a) throughout the happening and b) after the incident. It collected not only information and comments generated in federal and local governmental public profiles but in civil organizations and private user profiles as well. This paper describes how social media helped not only to socialize public information in order to prevent danger but it also served as a link between governmental dependencies and civil society to support affected communities after the event.

Opaque Poetics in Salvador Plascencia’s The People of Paper

“…The sadness of loss that was 'commodified' to drive the book is not gone: '[it] still circulated […] his liver never able to filter the melancholy, but his body had adapted'. 54 In writing this work, Saturn/Salvador has not seen through this patch of darkness so much as he has learned to live with it. The novel ends with a final opacity for the reader to address, as Federico de la Fe walks alongside his daughter little Merced, who 'raised her parasol, shading her and her father.…”

“…There would be no sequel to the sadness.' 55 The body of the text ends here, but over the page there is a twopage spread, all blank save a large black dot in the bottom right-hand corner. The dot perhaps represents Federico and Little Merced, seen from above and obscured by the parasol, but in the context of this artwork's end it is also the black sun of Julia Kristeva's melancholia, the dark and present absence of a struggle to align the self with loss.…”

Modelado de la transferencia de masa y reacciones en biorreactores anaerobios tubulares para la conversión de almidón no alimentario en bioetanol

“…Normalmente, este tipo de fermentación está dirigida a la producción de enzimas y metabolitos de alto valor agregado (García y col., 2006). El desarrollo de esta técnica permite el cultivo de organismos aeróbicos en condiciones homogéneas con una densidad moderada de la biomasa y simplifica el estudio de la fisiología de los organismos (Plascencia, 2009).…”

“…Al utilizar levaduras para la producción de bioetanol, la homogeneidad se vuelve una limitante para el proceso (Barrios-González y col., 1988). Sin embargo, de acuerdo con Plascencia (2009), en estos sistemas, la agitación mecánica permite aumentar la transferencia de masa de tres formas básicas:…”

“…La Fermentación en Estado Sólido se define como un cultivo de microorganismos adheridos a un soporte sólido poroso y humedecido, en el cual el medio líquido está impregnado en un soporte poroso con una interfase gaseosa (Plascencia, 2009). Las bacterias, levaduras y hongos son los microorganismos que pueden crecer en fermentación sólida, pero la mayoría de las investigaciones se llevan a cabo con hongos filamentosos (Holker y col., 2004).…”
