This study has as object of research the continuing education of the teacher trainers of the Training Centre of the State of Mato Grosso (CEFAPRO), aiming to investigate how the training process is composed in the Cefapro of Barra do Garças, with emphasis in the construction of professional knowledge. The study considered the continuing education process in progress and the teacher trainers were used as research subjects. The data were collected through interviews and theoretical arguments were used for their analysis to introduce the debate on the continuing education of teachers in the public policies for education, assuming that continued education includes the educational reforms in Brazil. We sought to understand the formation process in different dimensions and contexts, with theoretical foundation based on Nóvoa (1992, 1994, 1995, 1996, 2009), Marcelo García (1999, 2009), Imbernon (2002, 2009, 2010), Prada (1997, 2010), Tardif (2012), Freire (1979, 1982, 1996, 2001), among others. It is said that the continued formation of the Cefapro as a participatory proposal did not consolidate its training room for the construction of professional knowledge by the teacher trainers. The challenge for the continuing education of the Cefapro is to meet the educational policy, advancing beyond the limitations that it addresses to the practices committed to the transformation of the society
Termalização de qubits sujeitos à ação de reservatórios coletivos markovianos
(Universidade Federal de São Carlos, 2014-08-26) Diniz, Emanuel Cardozo; Villas-Bôas, Celso Jorge; https://lattes.cnpq.br/5700887540085418; https://lattes.cnpq.br/6386818101091884
We are interested in understanding the process of Markovian thermalization in quantum systems when we have one or two qubits interacting with a quantum electromagnetic field mode, using the Rabi model, in situations where there is interaction with a reservoir modeling the environment surrounding the system. This analysis of the thermalization is based on the calculation of the eigenvalues of the Liouvillian of the Markovian master equation. We will focus mainly on situations where there is interaction with independent and collective reservoirs, for cases where the subsystems interact with reservoirs at T=0K and T >0K. We investigate situations where there is no thermalization of the system and how this may influence interesting physical properties, such as the statistical properties of the field in the ultra strong scheme using the theory of input-output and quantum correlations between qubits collectively interacting with Markovian reservoirs.
Novas perspectivas para a comercialização de produtos agroecológicos: um estudo de caso em Hojarasca Carmen de Viboral, Colômbia
(Universidade Federal de São Carlos, 2014-08-26) Souza, Gabriela Ferreira de; Bertazzo, Cláudio José; https://lattes.cnpq.br/1154385746854757; https://lattes.cnpq.br/1398115392612782
The systematization of an agroecological transition and the local-regional markets is extremely important to build knowledge on this area. This systematization enable people, who are involved on this work, to have more precise information, increasing the success in the whole process. The present study systematizes a marketing initiative of agroecological products in Carmen de Viboral, Colombian, Antioquia department, from its agroecological transition, the development, until the concretion and stability of its initiative. The methodological approach was based on a notorious local peasant´s narrative, named Carlos Osorio, it was analyzed the reasons that induced him to work with agroecology, the emergence of a marketing channel, and the meeting with consumers, was take into consideration. It was also observed his present structural and organizational aspects; distinguishing its consumers and the strategies that he used to establish the initiative. It makes use of a semi-structured interview, a questionnaire and Diagnostic Rural Participative. The theoretical framework used was Van der Ploeg (2008) and the Stiologia Zaoual theory (2006). This case study shows the reasons that induced a person to change radically not only his life, but the relation he has taking care of the soil, agriculture, and also their lives. The peasant was succeed of closing a cycle, from its production until finding an autonomous commercialization channel for his agroecological products using mechanisms of symmetric reciprocity; enhancing important values, that our society relativized or even forget about, such as, confidence, solidarity, ethics, love, honesty and long-term planning.
A cultura punk e o underground: um estudo no cenário de duas cidades do interior paulista
(Universidade Federal de São Carlos, 2014-08-26) Oliveira, Bruno Pereira de; Dinis, Nilson Fernandes; DINIS, N. F.; https://lattes.cnpq.br/8750733554832790
This essay is the result of the analysis of history fragments and Punk culture, as well as some artistic productions by the members of this movement, as zines and musics utilized by the Punks to defend their ideals and to establish its position before a hegemonic culture imposed on then. The productions analysed are the main sources of data for the fulfillment of this research, because the sources selected allow for an analysis considering the proximity between the Punk culture and the Underground scene from some similarities found during the research, as the influence of the Counterculture and the fight before the imposed standards. With the intention to elaborate a bibliographic review, considering the possible relations between the Punk movement and the Underground, being these elements present in most urban centers, this research is directed to two cities from São Paulo inland, Atibaia and Bragança Paulista, each one with its own culture and behavior. In this essay other movements besides the Punk are cited merely as comparative elements, because the Punk movement, its Underground component allies and all it's set of practices and actions, provide the minimally necessary data for the analysis of the proximity between the Punk culture and the Underground.

Sodium intake is induced by facilitatory signals, such as angiotensin II (ANG II) and aldosterone. Hyperosmolarity and central cholinergic activation, classic antinatriorexigenic stimuli, also induce NaCl intake when the inhibitory mechanisms of the lateral parabrachial nucleus (LPBN) are deactivated. In the present study, we investigated the possible interaction between osmoreceptors and cholinergic and angiotensinergic mechanisms in the control of water and NaCl intake induced by different dipsogenic and/or natriorexigenic stimuli combined with the blockade of LPBN inhibitory mechanisms. Rats with stainless steel cannulas implanted in the lateral ventricle (LV) or subfornical organ (SFO) and bilaterally into the LPBN were used to study the effects of injections of atropine (muscarinic cholinergic antagonist), losartan or ZD 7155 (AT1 receptor antagonists) into the LV or SFO on water and 0.3 M NaCl intake induced by bilateral injections of moxonidine (α2- adrenoceptor/imidazoline agonist) into the LPBN combined with a) plasma hyperosmolarity induced by intragastric (ig) 2 M NaCl; b) injections of carbachol (cholinergic agonist) into the LV or SFO; c) subcutaneous injections of furosemide (FURO) and captopril (CAP); d) injection of ANG II into the LV. Additionally, we also investigated whether acute application of osmotic, angiotensinergic and cholinergic stimuli would activate cultured SFO dissociated cells and if the same cell would be activated by different stimuli. In rats treated with ig 2 M NaCl, injections of moxonidine (0.5 nmol/0.2 μl) into the LPBN increased water and 0.3 M NaCl intake. Injections into the LV or SFO of atropine (20 nmol/1.0 μl and 2 nmol/0.1 μl, respectively) or losartan (100 μg/1.0 μl and 1 μg/0.1 μl, respectively) abolished water and 0.3 M NaCl intake in rats treated with ig 2 M NaCl combined with moxonidine into the LPBN. Moxonidine injected into the LPBN also increased water and 0.3 M NaCl intake induced by FURO + CAP, injections of ANG II (50 ng/1.0 μl) and carbachol (4 nmol/1.0 μl) into the LV or carbachol (0.5 nmol/0.1 μl) into the SFO. The blockade of AT1 receptors with injections of losartan into the LV or ZD 7155 (1 μg/0.1 μl) into the SFO abolished water and 0.3 M NaCl intake in rats treated with carbachol into the LV or SFO combined with LPBN injections of moxonidine. However, atropine injected into the LV, despite reducing water intake, did not change 0.3 M NaCl intake in rats treated with FURO + CAP or injection of ANG II into the LV combined with injections of moxonidine into the LPBN. Injections of losartan into the LV reduced 0.06 M sucrose intake, but did not change food intake induced by 24 h of food deprivation. Finally, in vitro studies showed that osmotic, angiotensinergic and cholinergic stimuli activate SFO dissociated cells and that different stimuli can activate the same SFO cell. Therefore, the results of the present study suggest that different stimuli, such as hyperosmolarity and central cholinergic activation, facilitate NaCl intake through activation of central angiotensinergic mechanisms.
Caracterização magnética de compósitos multiferróicos particulados Pb(Zr0,52Ti0,48)O4/CoFe2O4
(Universidade Federal de São Carlos, 2014-08-26) Jimenez, Korllvary Rhanddy Charles Parra; Oliveira, Adilson Jesus Aparecido de; https://lattes.cnpq.br/4640148190073166; https://lattes.cnpq.br/9545814170516633
This work was studied the magnetic and electrical properties of particulate multiferroic composite Pb (Zr0,52Ti0,48) O4 / CoFe2O4 (PZT / CFO) (0-3 type) prepared by the polymeric method of Pechini and sintered by ultra-rapid method in microwave and conventional oven, with two molar concentration (80/20 and 50/50). These samples were characterized by ferroelectricity measurements as a function of applied electric field. And magnetization, magnetostriction and magnetoelectric effect as a function of magnetic applied. The main goal of our study was to analyze and characterization of the magnetic and magnetoeletric dependence of particulate composites PZT / CFO, where these samples exhibits two different grains size distribution of cobalt ferrite when compared of grain size average of PZT matrix, with two methods of sintering. We observed these samples present a dependence of the magnetic properties with the methods of sintering and the average grain size of ferrimagnetic phase. This effect was observed in the electric polarization of the ferroelectric PZT. In addition, differences were observed in the magnetic properties 5K and 300K, especially in the coercive field, for samples of cobalt ferrite and composite PZT / CFO 50/50, associated to differences of apparent densities.
