The present study aimed to analyze how develops the reverse logistics process applied in electrical and electronic products. Such analysis was obtained through literature search and with the completion of a case study, which was developed at the company's Oxil Reverse Manufacture, showing the advantages obtained as well as the difficulties faced in the implementation of the reverse logistics process. The development of this research shows its importance in so far as the residues generated by electronic components, which are one of the most harmful to the environment and harmful to human health, highly possessing heavy metals and non-biodegradable materials in their composition. In this way, the components collected from this activity, should be properly recycled, reused and finally housed in suitable location, these steps that are part of the reverse logistics process

The 131I (radioactive iodine) is one of the most used radionuclides in nuclear medicine for diagnosis and treatment. The present study evaluates the dosimetric aspects related to radioiodine therapy after thyroidectomy in patients with thyroid cancer. The samples were studied with 50 patients undergoing treatment, by assessing the exposures of workers (nursing assistants, staff hygiene, medical and physical), the general public (accompanying and family members) and on the environment. To evaluate the workers, was made a survey of the environmental conditions of the room radioiodine and routines adopted by them during the treatment period. Estimating the dose equivalent per month for each employee, we observed that the maximum levels obtained for nursing assistants, the team of hygiene, medical and physicians were considered low in relation to the extent permitted by law. In order to assess the public, some situations have been suggested for the calculation of equivalent doses in which it was possible to verify the fundamental importance of isolating the patient in the 2 days first. Regarding the environment, the radioactive waste generated by patient had volume of 1.0 m3 and activity estimated at 0.91 mCi, taking a decay time for eliminating them about 75 days to reach the allowable value of 2 μCi / kg system of collecting garbage. Therefore, all radioactive waste removed from the patient's room should be sent to the warehouse for temporary storage of radioactive waste, located away from normal work areas

At the beginning of the 21st century, several crises are intertwined and the environmental crisis is the most global of them all. For a complex and global crisis, which has implications of a social, economic, technological nature, etc., solutions will probably not come from a single source, but rather the sum of efforts of society as a whole (including all its instances, government, business, population, etc.). The objective of this review was to discuss the need to produce “environmental” professionals who, through their activities, are in some way involved with the quality of the environment. We believe that, ultimately, it is the quality of the environment that will ensure the quality of life in a fairer society. Thinking about the training of teachers, as environmental educators in undergraduate (bachelor) universities, means having as a reference the idea of wholeness (environmental, political, educational, social, scientific, etc.) in the diversity that these areas possess. Even though there are many difficulties involved in getting this topic included in the university structure, based on a complex approach, we believe this is one of the best paths toward environmental training.

As demonstrações experimentais são atividades de grande tradição na História da Ciência, sendo realizadas desde 1660 na Royal Society, por grandes expoentes da Física, com o objetivo de promover a divulgação dos conhecimentos científicos desenvolvidos.Com o objetivo de contribuir com a melhoria e o interesse dos alunos pelos estudos das Ciências Exatas, bem como a conscientização destes sobre conceitos relacionados à Energia e seu impacto sobre a sociedade e sobre o meio ambiente, temos realizado atividades de demonstrações experimentais, denominadas de “Show de Energia”, nas escolas públicas de Ensino Médio de cidades da Região de Guaratinguetá, interior do Estado de São Paulo. Em cada um dos shows realizados entrevistamos os alunos, através de um questionário estruturado, buscando avaliar o impacto dessa atividade na motivação dos estudantes para o aprendizado de conceitos científicos. Os resultados apontam para a grande influência que a realização dos shows tem exercido sobre a motivação dos estudantes.
