Abstract:

Extreme rainfall events can be considered a natural manifestation of the environment in which they are embedded and foreknowledge about their future behavior is very important, especially for decision makers. In this context, we aimed to explore the future behavior of extreme rainfall intensity through numerical simulations with the ETA model. The model was forced with a scenario of high greenhouse gas emissions for the middle of the 21st Century as described for A1B emission scenario. We detailed the main changes in accumulated rainfall produced by heavy events, very heavy events and rare events over a broad area of South America with a focus on the tropical sector. The methodology applied here is capable of separating extreme events and establishing the quantity of rainfall yielded by them. We have found that in the near future (2041-2050) rare events will tend to increase over the Amazon basin, followed by reductions in heavy and very heavy events. Conversely, heavy, very heavy and rare events are expected to decline over north-east Brazil. Furthermore, increases were found for heavy, very heavy and rare events over southern Brazil.

Abstract: repetitive behavior, stereotypies and restricted interests are some of the main symptoms that compound the asperger?s disorder. however, until what point is possible to differentiate them from obsessive-compulsive symptoms that meet criteria for obsessive-compulsive disorder (ocd)? many times, that?s not possible. this work reports the case of a patient with asperger syndrome and ocd. we bring up until what point is really important the distinction of ocd as a comorbidity different from asperger, and also our therapeutic conduct, in which high doses of a selective serotonin reuptake inhibitor - ssri - (fluoxetine) was fundamental to a better socio-occupational adjustment of the patient, significantly improving his quality of life.

Abstract: Se realizó la construcción y validación de un test psicométrico para la determinación de vulnerabilidad al estrés. El test, denominado cuestionario vulnerabilidad estrés, fue realizado básicamente a partir de la batería psicométrico del método de enfoque sistémico de evaluación del estrés. Se confeccionó un cuestionario inicial de 63 ítems y 3 subescalas con el que se realizó un estudio piloto; al depurarlo, la forma definitiva fue redactada con 39 ítems y sometida a un estudio para determinar fiabilidad y validez. Se determinó una estructura trifactorial coincidente con el dise o previo. La consistencia interna fue de 0,92 según el alfa de Cronbach y de 0,90 con el coeficiente de Spearman-Brown. Se encontró una correlación test-retest de 0,97 y se correlacionó además, de forma significativa con criterios externos de vulnerabilidad-escala de neuroticismo del test de Eysenck, ansiedad como rasgo de Spielberger y el criterio clínico. Se concluyó que el cuestionario vulnerabilidad estrés constituye un instrumento válido y fiable para medir vulnerabilidad al estrés sobre la base del método de enfoque sistémico.

Abstract: the purpose of this article was to analyze sexual diversity and homophobia in the portuguese educational environment, through a comparative study between the results of the 'sexuality, youth, and adolescent pregnancy in northwestern portugal' study and the existing data of the report on homophobia and transphobia from the 'glbt education observatory'. qualitative methodology was used in the first study, while quantitative methodology was used in the second. both studies concluded that most young people present a negative attitude towards glbt people, misinformation about sexual diversity, accompanied by a high diffusion of myths and stereotypes, which result in homophobic and sexist attitudes. school remains a privileged environment to the construction of identity, but it is unprepared to deal with the issue of sexual diversity; education concerning sexual-affective diversity is a task for everyone.
Biocorrosion of mild steel by SRB: electrochemical studies
Fonseca, Inês T.E.;Feio, M. José;Lino, Ana R.;Rainha, Valter L.;
Journal of the Brazilian Chemical Society , 1997, DOI: 10.1590/S0103-50531997000200008
Abstract: electrochemical studies of the biocorrosion of mild steel in the presence and absence of sulfate reducing bacteria (srb) grown in lactate/sulfate and lactate/nitrate aqueous media were performed. open circuit potential measurements revealed a displacement of the potential in the noble direction in both media. however, regular oscillations in the potential were observed only in the lactate/sulfate medium. sem micrographs showned pits clearly distributed over the surface of the steel samples exposed to srb cultures in both media, with small size and more uniform pits in the lactate/sulfate media, in agreement with the open circuit potential data. cyclic voltammetry clearly shows that the srbs grown in the lactate/sulfate medium lead to high dissolution rates in the transpassive region with the formation of fe(iii) species.
