The research is linked with the Education StrictuSensu Post-Graduation Program of UFSCar – Sorocaba and started with the participation in a group of homosexual/transgenderparents that used to arrange meetings of mutual help to fight against homophobia in the family context, the GPH, that has been established as a public policy in Sorocaba-SP since April/2013. The investigation was takento find out the limits and possibilities of this homophobia combat space through the presentation and analysis of categories and social conventions that merge there. From the theoretical field of gender and post-structuralistsexuality, it was sought to investigate the relations between families and homosexual/transgender, particularly the lives of the parents with the objective of comprehending and integrating their children. Because learning and investigating this relationship space is a process that cannot be measured to quantifiable variables, this research is qualitative. The methodological work was accomplished through the bibliographical research of documents and field studies, using the following procedures: documental analysis, interviews, prioritizing the participating observation and speech quantitative analysis in the perspective of events that took place in the maternity. The most difficult elements of this journey is the binary speech inheritance – man/woman, male/female, straight/homo – produced and reproduced daily inside the homophobic speech as in those that in some way are favorable to gender diversity and sexual orientation. The difficulties felt and supposedly faced by the GPH parents and the categories and social conventions mobilized in this journey were considered to be linked to differences built – social and culturally – translated in power relationships that rank gender, rendering inferior all forms that do not correspond to the linearity of sex, gender, desire and sexual practice. The implementation and participation at the GPH Sorocaba shown, not only the strength of heteronormativity, but also that the different fugitive form of being and living the genders and sexualities, generally not accepted but tolerated, highlighting that there is no social convention detachment in this context. At the same time, the attribution of new senses, the questioning of built “truths” that, for a long time, were naturalized and reproduced by these LGBT parents shows that public policies aimed to homophobic confrontation in family context have an important role to mitigate it.
"Fotoquímica “verde”: desenvolvimento de complexos de metais de transição luminescentes para ativação de oxigênio singleto e a sua aplicação na desinfecção de água contaminada com microorganismos patogênicos (Escherichia Coli e Enterococcus Faecalis)”

Green Photochemistry: Development of transition metal complexes for activation of luminescent singlet oxygen and its application in the disinfection of wastewaters contaminated with pathogenic microorganisms (Escherichia coli and Enterococcus faecalis). The development of the perylenes derivatives complexes Ru (II) and Re (I) has received increasing attention in energy transfer. Here in we investigated, the synthesis, characterization, energy transfer studies and biological testing of three complexes of Ru (II) and Re (I) cis-RuCl2(PDI1)2, cis-RuCl2(1,10- phen)(PDI1 ), fac-[Re(CO)3(PDI1)Br] and [Ru(1,10-phen)2(PDI2)]2+. The complexes are simple and stable preparation of both solid as well as DMSO solution (in the absence and presence of light) and are resistant to hydrolysis at pH 4 to 8. All compounds were characterized by 1H NMR, IV, elemental analysis and theoretical calculations whose results were consistent with the proposed structural. The complexes exhibit intense absorption in the visible region (500 nm, ε = 20,000 mol-1Lcm-1) and an intense band emission around 600nm, long emission lifetime 500 nsec and a small Stokes shift (600 cm-1), consistent with the rigid structure of the perylene chromophore. We observed that some complexes have paramagnetism ability in the ground state and both solution and on solid medium which was confirmed by RPE and theoretical calculation. These complexes were not able to produce photochemical 1O2. However, [Ru(1,10-phen)2(PDI2)]2+ presented photochemical generation of 1O2 dissolved in methanol, ethanol, acetone and acetonitrile and quantum yield of the formation of this species (Φ1O2) in order 0.30. Thus, we immobilize this complex on silica gel functionalized with aminopropyl group and it produced 1O2 with Φ1O2 around 0.20. The ability microbicide of these complexes were tested against the yeast Candida and values obtained show they are toxic for these microorganisms. These results lead us to believe that the complex can act on wastewater treatment.
