Objective: to evaluate the standardization of vaccination rooms in the Municipality of Marília, State of São Paulo, Brazil. Methods: descriptive and exploratory study, realized in 2008-2009; the instrument used was the Supervision in Vaccination Rooms, of the Ministry of Health; variables analyzed were general aspects of the vaccination room, technical procedures, cold chain, information system, post-vaccination adverse events, special immunobiologicals, epidemiological surveillance and health education; the score achieved classifies the room (90.0-100.0% = ideal; 76.0-89.0% = good; 50.0-75.0% = fair; <50.0% = insufficient); overall index for each point was calculated as the average score of all rooms. Results: technical procedures, information system, post-vaccination adverse events and special immunobiologicals were scored as ideal; cold chain, epidemiological surveillance and health education were scored as good; and to general aspects of the vaccination room, the evaluation was fair. Conclusion: general index for vaccination rooms in the municipality was considered ideal.

Based on fish production performance, this study assessed the feasibility of replacing SBM with CSM in practical diets for cage-raised Nile tilapia during the finishing phase. To accomplish this research, four isoproteic (32% CP) and isoenergetic (2500 Kcal/kg of DE) diets were formulated. Control diet (T1) contained 30 % of SBM and 0% of CSM. The other three diets contained: 20% of SBM and 10% of CSM (T2), 10% of SBM and 20% of CSM (T3) and 0% of SBM and 30% of CSM (T4). Lysine and Methionine deficiency was compensated for with synthetic amino acid (L-lysine and DL- methionine) supplementation. Experimental design was completely randomized with four treatments and four repetitions. Data were analyzed with SAS PROC GLM through co-variance analysis, adding initial mean weight as a co-variable, followed by Dunnett test. The system used to calculate the profit part was Partial Budget Analysis in Aquaculture, proposed by Shang (1990). Profit was significantly different at T3 when compared to T1 (control). It was concluded that the addition of 20% of CSM to finishing diets can improve cage-raised Nile tilapia profitability.

Depuis que l'électricité a été découverte et que le secteur électrique s'est considérablement développé dans le XVIIIe siècle, jamais l'homme n'a pu se détacher de cette énergie. Pendant longtemps le système d'énergie électrique a fonctionné sans grand changement, mais avec le développement rapide des technologies, de nouvelles améliorations apparaissent. Ce mémoire traite des nouveaux concepts de réseaux d'énergie électrique appelés Réseaux intelligents ou Smart Grid. À travers un panorama de leurs développements dans le monde, cette étude porte d'une part, sur l'avancée des projets dans quelques pays et d'autre part, du niveau de développement de ce réseau au Brésil et de son intérêt pour le pays. L'étude a comme point central un des composants de ce réseau intelligent, le compteur communicant, qui est l'élément essentiel des interconnexions entre consommateurs et producteurs. Ce rapport apporte un éclaircissement sur les compteurs conventionnels et les compteurs intelligents et sur leur mode de fonctionnement. Enfin il aborde la question des consommateurs : par quels moyens leur transmettre tous ces changements à venir, puisque jusqu'à présent, leur seule participation était de payer l'énergie consommée. Avec le nouveau réseau, ils deviendront de véritables acteurs puisqu'ils seront informés en temps réel de leur consommation d'énergie électrique. Pour terminer, le mémoire montrera comment ils pourront s'adapter à cette nouvelle façon de gérer leur consommation en ésperant les inciter à une utilisation plus raisonnable de l'énergie et à modifier leur comportement en gérant de manière active leur consommation en intégrant notamment les énergies renouvelables

Special Education includes gifted students. There is a lack of resources and information for identification and care of such students. They were research objectives map students with giftedness characteristic in Elementary and Middle School in Bauru/SP, as well as verify what teachers know about the issue and if they know how to work with such students in their classrooms. This qualitative, quantitative and descriptive research was structured in three stages. Step A: an observation guide of gifted children, Guia de observação de crianças dotadas e talentosas. Step B: True or False questions on the subject. Step C, field diary. Two hundred and thirty one classes from 24 schools were evaluated and 477 students were identified with giftedness characteristic in at least one of six possible areas. Three hundred and one students were in Elementary School and 176 were in Middle School. In Step B, 280 teachers from 26 schools were part of this study and it is confirmed that they have theoretical knowledge on the subject because the number of hits on the main concepts (based on the literature) was superior to the number of misses. A 4th grade classroom, with a gifted girl, was observed in step C. It was found that the teacher pedagogical practice and the resources used are not different from the ones used with other students. Thus, it appears that the student has not received the curricular adaptations to assist her developing skills

A transmissão de Doenças Sexualmente Transmissíveis (DSTs) tem aumentado significativamente nos últimos anos entre os adolescentes, como apresentam os dados do Boletim Epidemiológico de AIDS publicado pelo Ministério da Saúde, juntamente com o aumento do número de adolescentes grávidas. Dessa forma, o projeto de extensão PET - Saúde objetiva transmitir um conhecimento prevencionista aos jovens vulneráveis a essa situação, trabalhando com estudantes do ciclo II do ensino fundamental dos colégios municipais de Nova Europa. Os alunos que participaram da atividade responderam voluntariamente um questionário antes e após a atividade, que avaliava qualitativamente o conhecimento que possuíam acerca do tema DSTs e gravidez na adolescência. Através da análise desses questionários, foi possível perceber que os jovens possuíam conhecimento sobre o uso de preservativo para a prevenção de DSTs e gravidez (86,9% e 82,8%), mas que o mesmo não se aplicava quanto ao conhecimento de sintomas de DSTs (66,8%), que foi aprimorado após a atividade (80%). Além disso, as meninas apresentaram conhecimento acerca de outros métodos contraceptivos diferentes do preservativo e importância da vacina contra o HPV, provavelmente pelo fato dos meninos lidarem com a vida sexual de uma forma diferente. Apesar de conhecimento prévio sobre o assunto, ações educativas contínuas podem aumentar o conhecimento dos jovens sobre DSTs e gravidez.

In this paper, we will present an overview of the smart grid defining the three main systems that compose it: smart infrastructure system, smart management system and smart protection system. We will conceptualize a functionality of smart management system, the conservative voltage reduction, citing its benefits and its history of application. And, finally, we'll cover a test in which we reduce the nominal voltages on incandescent bulbs, CFL and LED, in the context of residential lighting, and on LED and HPS, in the context of public lighting. The test aims to check whether the voltage reduction adversely affects sources of lighting by measuring the temperature manually with a thermal imaging camera FLIR and illuminance with a LUX meter. The set of power factor, total harmonic distortion, and input power values will be collected automatically through the power quality Analyzer Fluke 345 with a probe Fluke Hall Effect Current. For residential lighting, it was found that both CFL and LED had good performance with the smallest variations in illuminance. Between both, the LED source had the lowest harmonics and the lowest power consumption, on the other hand incandescent bulbs had a bad performance as expected. Public light sources also had a good performance and obtained power factors within the standards, as opposed to the CFL and LED residential sources. The data collected clearly shows the feasibility for nominal voltage reductions. Even with small reductions, there are possibilities of savings which can be passed on to the utilities and consumers
