The present paper proposes an analysis about the Brazilian Psychiatric Reform as a public policy and deriving from a research developed with the workers of a Psychosocial Attention Centre III (CAPS III) and the managers of the Psychosocial Attention Web (REAP) in Aracaju. This analysis is developed as an investigation of the discharge at those services, understood not as a procedure, but as a dispositive from which different elements can be articulated: users, knowledge, technical procedures, police measures, juridical decisions, laws, services edifying. This, form the background of the articulation between mental alienation and the subject of right alienation, in the ways through which this articulation develops to the relations between madness,citizenship, internment and substitutive practices. Our investigation about the discharge as a dispositive was built with some narrative constructions, as a discourse analysis inspired by Michel Foucault s method, from the perspective of some of the main dispositive operators: workers and managers. The main aspect observed were: the articulations built by the discharge as a dispositive based on two discursive grate, the Reform as a new treatment substituting internship, and the Reform as juridical insertion and users rights practice; the exercise of these discursive grades based on the workers and managers perspective; the transference of limitations and contradictions of these grades to the competence of the dispositive operators, emerged in an outstanding way, as sometimes those operators are liable for the emergent limitations and difficulties, and some other times they are restrained by their institutional role, which is to maintain the domination relations articulated by the dispositive; finally, some aspects extracted which the dispositive operators - when they were expected to act in a way to maintain certain power relations - were capable to resist, managing other power relations from the dispositive, that we call, as Agamben, dispositive profanity

Dezesseis cabras nulíparas da raça Saanen foram distribuídas em dois grupos de tratamentos (T1 e T2) para sincronização da ovulação. Inicialmente, ambos os tratamento consistiram na aplicação concomitante do dispositivo de liberação controlada de drogas (CIDR-G®), de 5mg de dinoprost e de 1mg de cipionato de estradiol (CE) (dia 0). No quarto dia aplicaram-se 250UI de eCG e no quinto dia retirou-se o CIDR-G®. As cabras do T1 (n=8) receberam 1mg de CE 24 horas depois da retirada do CIDR-G® e as do T2 (n=8) receberam 250UI de hCG 30 horas após. Sete cabras do T1 e oito do T2 entraram em estro depois da retirada do CIDR-G®. Cabras que receberam hCG permaneceram em estro por 42,0± 6,9 horas e as que receberam CE por 45,0± 5,5 horas (P>0,05). As características ovulatórias não foram influenciadas pelos tratamentos. O intervalo da retirada do CIDR-G® à ovulação para ambos os protocolos de sincronização da ovulação não diferiu (P>0,05) entre tratamentos. As ovulações promovidas pelo CE ocorreram em menor intervalo de tempo.

This paper describes the drawing, construction and optimization of a device, which can be used to obtain single crystals of different metallic materials with melting point from 550 to 1050°C. Components of ease obtaining and of low cost were used. The device was based on the modified Bridgman technique and it was used to obtain single crystals of copper-based alloys. The temperature axial profiles and a difference less then 1% in the temperature between the wall and the center of the ceramic tube in the critical region for obtaining single crystals of good quality indicated that the oven presents a good thermal stability. Single crystals of CuZnAl and CuAlAg alloys of good quality were growth and characterized using optical microscopy and Laüe X-ray back reflection.
