Treatment of Dynamic Mixture of -Hexane, Benzene, and Methanol and Fungi Community Characterization in an Integrated Scheme of Cyclic Adsorption/Desorption Beds and Trickle Bed Air Biofilter

This study investigates the effect of volatile organic compound (VOC) feed fluctuations on trickle bed air biofilters (TBABs) and the ability of a two-bed adsorption/desorption unit in dampening fluctuations. A mixture of n -hexane, benzene, and methanol with concentration ratios of 1:3:6.6 was fed to two parallel TBABs. To simulate feed fluctuations, four different square waves were applied. The total VOC loading rates (LRs) varied from 28.4 to 107.3 g/m 3 h. The average concentration of VOCs applied to both TBABs was within allowable limits as determined in an earlier study. One TBAB was preceded by a two-bed cyclic adsorption/desorption unit (integrated unit), while the other TBAB (control unit) was directly subjected to the high and low peaks. n -Hexane elimination in the integrated unit was steady, and stable performance was obtained (75%-89%) based on the LRs, whereas the control unit showed erratic performance. The other two VOCs were mostly removed

Da racialização do sexismo ao sexismo identitário entre imigrantes na França contemporânea From racialization to identitary sexism among immigrants in contemporary France

Este texto examina a maneira como o racismo manipula a denúncia do sexismo e apresenta os efeitos desses discursos sobre as pessoas que são alvo de discriminação. Sustenta que, longe de diminuir as violências sexistas, as lógicas racistas que se escondem atrás do anti-sexismo tendem a reforçá-las. Nossa demonstração se apóia em dados recolhidos durante uma pesquisa sobre a experiência do racismo, sexualidade e a gestão dos riscos de infecção por HIV, conduzida entre 1997 e 2003 junto a 69 jovens, homens e mulheres, de idade entre 18 e 25 anos, na França.<br>This paper analyzes the way racism manipulates accusations of racism, and presents the effects of such discourses on discriminated individuals. It argues that, far from reducing sexist violence, the racist logic concealed by anti-sexism tends to reinforce it. Our theses is based on data collected in a survey on experiences of racism, sexuality and HIV-infection risks management, carried out from 1997 to 2003, among 69 young males and females, aged 18-25 years, in France
