Brasil - Argentina e o Sistema Regional de Salvaguardas Nucleares

In 2011, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), created to administer the Common System of Accounting and Control of Nuclear Material (CSAC) has completed twenty years of existence. ABACC and the Quadripartite Agreement established with International Atomic Energy Agency (IAEA) are a special system of safeguards that presents itself as an important example of regional contribution to global nuclear proliferation. The paper presents some considerations about the process of understanding between Brazil and Argentina that resulted in the creation of ABACC, indicates succinctly some theoretical explanations of international relations for this process and, from some features of the Agency, relates how the ABACC experience could support nuclear weapons free zones.

Sistema de Aquisição de Baixo Custo para um Dinamômetro Biomédico

Objective: to create a purchasing system for optimizing a low cost device fabrication itself. Method: For this purpose was designed a system which is powered by a 12V battery center. The full bridge of "Wheatstone" is powered by the central battery set to 9V. Results: The sign of the strain has a range of 0 to 30 mV which is amplified filtered by a signal conditioner own manufacturing using an LM 324. The electrical signal then passes to vary from 0 to5V which will be processed in an analog input of PIC microcontroller. Tests for the registration and interpretation of data are through software MyOpenLab. Conclusion: The work is in progress and initial results suggest that the system will be able to measure muscular strength accurately and cost-effective.

Comparação de custo e viabilidade técnica de obras com parede de concreto em relação a obras de alvenaria estrutural

Are being released in the construction market in Brazil ventures called Super 6. These businesses sell the promise of delivery of the apartment in six months after the launch of the venture. To meet this deadline are being deployed the constructive method of concrete walls using aluminum shapes. This system basically consists of pouring slabs and walls once, i.e. building up the wall shapes and slab joints. On the walls are used cloth, with reinforcements in vain and corners of walls and on these screens are tied the electrical boxes and conduits. For each tower is used the so-called system of half way, i.e. the system so it is sufficient to mount the Middle deck. Using a concrete which can be deformed in the next day you can lift one deck every two days with ready electric and hydraulicsystem, without having to tow the wall doing only minor fixes in the imperfections after concrete. With this system won an incredible speed in the construction of the structure reducing in almost one-third the length of the work. This work aims to compare in terms of cost-benefit of masonry structural systems and this new concrete wall system called Super 6. For this comparison will be used as parameter values used for the achievement of the Enterprise Portal of Roses of constructor Tenda which is one of the first to use concrete wall system. This project basically consists of seven towers of six floors each and will be budgeted the cost of this project if it were held in structural masonry. From these data it will be possible to make a comparison about the actual beneficial to adopt this system

Acogimiento en el proceso de formación de los odontologos en Brasil: un analisis en el contexto del Sistema Unico de Salud (SUS)

To define the profile of Dentistry’s academics, on the welcoming reception of patients/users attended in the Public Institution, under the guidelines of the SUS. Methods: A structured questionnaire was applied to 163 students, which contained questions that covered five variables (reception, dialogue and listening, action and care first contact, professional identity) and conducted an interview to associate to responses obtained during the first phase. Quantitative data were tabulated and analyzed by descriptive statistics in SPSS 16.0 and qualitative data analyzed through discourse of the collective subject. Results: It was observed that, intellectually, the most of student (70.7%) understand the concept and the repercussion of the welcoming reception process in health and many have caring characteristics. However, the pedagogic system formation makes it difficult or systemizes an integral and spontaneous welcoming action. Conclusions: The academics have the embracement profile but it is need more motivation in the humanization of the university teaching.

Proposta de um sistema de monitoramento do processo de retificação plana baseado em plataforma de hardware livre e sensor de baixo custo

O processo de retificação é considerado um dos últimos na cadeia de produção de peças de precisão. Assim, é essencial ter um sistema de monitoramento confiável para este processo. Neste trabalho é proposto um sistema de medição de vibração, rápido e versátil, baseado na plataforma de prototipagem eletrônica de hardware livre Arduino, com objetivo de monitorar em tempo real o processo de retificação plana, especialmente no que diz respeito à condição da peça retificada. Para este trabalho ensaios experimentais foram realizados numa máquina retificadora plana, empregando um rebolo de óxido de alumínio e uma peça de aço ABNT 1020. Por meio de um sensor piezelétrico de PZT (Pb-Lead Zirconate Titanate) de baixo custo, instalado junto à peça e conectado a uma das portas analógicas do hardware, foi possível medir o sinal de vibração durante o processo de retificação. Verificou-se que, a medida com que o rebolo perdia sua capacidade de corte, em função das consecutivas passadas sobre a peça, ocorria também uma significativa diminuição dos valores médios do sinal de vibração. Tal diminuição do sinal de vibração pode indicar o momento que o rebolo deve ser dressado, permitindo monitorar a qualidade superficial da peça durante o processo de retificação, evitando danos como é o caso da queima superficial. O princípio de operação e as principais características dessa técnica foram investigados, bem como algumas de suas limitações práticas.
