The media on violence against women: the paradigm of thinness

This article attempts to show that the aesthetic pressure through the media, especially exerted on women, can be defined as gender violence; and the consequences of thinness paradigm of our society and obesity stigma that this entails have for their bio-psycho-social health.

Quel est le sens de l’équation "Le media est le message?

Il y a un malentendu en ce qui concerne l’expression « Le media est le message » de Marshall McLuhan, car l'on méprend le sens du mot anglais médium pour l’acception canadienne de média, comme dans l’expression mass media/médias de masse. Dans cet article, Mark Federman, nous apprend qu’un media est une extension de l’être humain et que le message est le changement que le media suscite dans notre environnement.

Development of a modified flyash as a permeable reactive barrier media for a former manufactured gas plant site Northern Ireland

A sequential biological permeable reactive barrier (PRB) was determined to be the best option for remediating groundwater that has become contaminated with a wide range of organic contaminants (i.e., benzene, toluene, ethylbenzene, xylene and polyaromatic hydrocarbons), heavy metals (i.e., lead and arsenic), and cyanide at a former manufactured gas plant after 150 years of operation in Portadown, Northern Ireland. The objective of this study was to develop a modified flyash that could be used in the initial cell within a sequential biological PRB to filter complex contaminated groundwater containing ammonium. Flyash modified with lime (CaOH) and alum was subjected to a series of batch tests which investigated the modified cation exchange capacity (CEC) and rate of removal of anions and cations from the solution. These tests showed that a high flyash composition medium (80%) could remove 8.65 mol of ammonium contaminant for every kilogram of medium. The modified CEC procedure ruled out the possibility of cation exchange as the major removal mechanism. The medium could also adsorb anions as well as cations (i.e., Pb and Cr), but not with the same capacity. The initial mechanism for Pb and Cr removal is probably precipitation. This is followed by sorption, which is possibly the only mechanism for the removal of dichromate anions. Scanning electron microscopic analysis revealed very small (
