The experimentation in the teaching of physics has been extensively studied over the years because of its potential as a tool demonstration of physics phenomena studied in classroom. In such a perspective view of the action of apprentice student involving teaching future teachers of physics, under the Program PIBID CAPES, developed since 2009, seeks ways to improve the teaching of physics experiments using the theme chosen for the electrostatic work was . In this particular work, we report the development of the project in a State School located in the city of Rio Claro, in two rooms in the 9th grade in elementary school. It is planned with the activities of teaching physics at this level of education, look at how two different ways of displaying the contents of electrostatics in a playful way for elementary students and implement a library of experiments so that students can take the experiments to their homes

This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept

Here we present an exploratory study on the use of laboratory teaching in four schools of Basic Education in Rio Claro, SP, three of them high school and one of the second cycle of basic education, developed in the years 2011 and 2012, under activities of the course Prática de Ensino e Estágio Supervisionado, the Degree in Physics - UNESP, Rio Claro campus and work with Pibid (Projeto Institucional de Bolsa de Iniciação à Docência) in agreement UNESP CAPES Notice 2009. Initially, we diagnose the situation and identify the laboratories using them for Teaching Physics, from direct observation and contact with teachers. Based on the experimental realization of educational activities in such schools, we discuss different teaching strategies, and using experiments built with inexpensive materials (Ferreira and Ramos, 2008). We analyzed the role of the teaching laboratory in the development of skills and abilities of students, related to the teaching and learning of Physics, as well as aspects concerning the use of instructional laboratories

Increasingly competitive markets have driven the search for companies in many different ways to win and keep customers. The service level is basically the performance of companies in fulfilling the orders made, or how companies demonstrate to their clients efforts in their behalf. This work aims to solve the difficulties faced by a multinational company present in Brazil, in the distribution of its products in the category Ice Cream in order to improve the service level of their customers. Review the logistics network and concepts related to the distribution system of products is one of several ways to achieve this goal, as well as the use of IT and tools to assist in planning and programming of the physical distribution of products. In this study we used the concept of direct distribution system called Transit Point (TP). The TP provides at the same time, a strategy of rapid response, flexibility, low transportation costs and no inventory. A router - software capable of simulating the actual conditions experienced in the daily distribution - was used to assist in calculations. Results showed reductions of up to 47.5% in transportation costs and better conditions were provided in the distribution of products, positively impacting on service levels and in the maintenance of products quality, with a reduction of 1.6% of the total costs involve

The research shows that increasing the consumption of energy by households is growing rapidly and without adequate planning, due to population growth and therefore an increase in energy consumption. With the current concerns of sustainability and energy efficiency by industry, there is the need to prove to population that there are many ways to incorporate sustainable practices to their daily lives, starting from by their own residence. The quality certification of the energy efficiency level in residential buildings, shows how one can influence and improve housing issues on sustainable actions as rooted in our country

Nuclear Medicine is a medical modality of therapy and diagnostic imaging using unsealed radioactive sources for its purposes. This routine activity promotes the transit of radioactive sources for the area of installation, beyond the transit of patients injected with radioisotope, which also contribute to raising the radiometric level of environment. As a consequence, it has exposured workers and public individuals to the ionizing radiation. There are protective mechanisms of radiation exposure, personal protective equipments, and measurement planes established in standard measurement at certain points of the environment in order to identify any increase in radiometric levels and \ or contamination, but do not cover the entire space occupied by workers and patients. To accomplish with the individual dose limits established by the National Commission of Nuclear Energy, it is interesting if there is an individualized classification for each Nuclear Medicine service. This work aimed to promote an analysis of the radiometric level distribution across the extent of the Technical Nuclear Medicine Sector of Hospital of the Botucatu Medical School, and produce a spatial map to identify locations with higher exposure rate to the ionizing radiation, can be used as a risk map to assist the Occupationally Exposed Individuals (IOE). To perform the radiometric levels checking it was used a digital Geiger-Muller detector available in the sector, due to its practicality compared to other detectors. Measurements were carried out at four different times for all days of the week, at points strategically established to cover all the installation

The process of product development (PPD) is a strategic factor in which companies seek to identify consumer needs. The relationship of the practices adopted, tools, techniques, among others, can determinate the maturity level of the company in this process. The purpose of this paper is to understand and diagnose the level of maturity of the PDP in footwear segment industry. For the case study, a company inserted into one of the largest poles of women’s footwear in Brazil, located in Jaú, São Paulo State, was researched. The diagnosis is based on the maturity levels of the unified model, reference in the process of product development, proposed by Rozenfeld et al. (2006). The application of the model assisted to diagnose the current maturity level of the company in this process, providing useful information to achieve higher levels of maturity in the PDP.

A comparação visual com escalas de cor, universalmente empregada para avaliar o resultado das diferentes substâncias, técnicas e aparelhos utilizados no clareamento dental, tem se mostrado um método limitado, questionável, subjetivo e pouco confiável. Os métodos instrumentais, que utilizam espectroscópios ou imagens digitais, têm se mostrado mais adequados por oferecerem avaliações objetivas, maior reprodutibilidade e confiabilidade. Neste artigo, serão apresentados e discutidos os resultados obtidos com a utilização do ScanWhite© ? software para avaliação objetiva do nível de clareamento dental e apoio à decisão clínica, que baseia sua avaliação no processamento computacional de imagens digitais. Esse tem como principais diferenciais: (1) algoritmo calibrador para compensar as variações de luminosidade do ambiente, (2) apresentação dos resultados em valores numéricos e através do gráfico de evolução do clareamento dental, (3) interface intuitiva e facilidade de uso, (4) determinação dos índices de apoio à decisão (IPS ? índice de possibilidade de sucesso, e IRS ? índice de risco de sensibilidade antes do início do tratamento) e (5) emissão de relatório geral, autorizações e recomendações pós-clareamento.
