The knowledge of the mechanical behavior and metallic materials when subjected to unconventional situations which involve shear rates is still largely unexplored in the literature in general. One reason for this lack of knowledge is, in fact, the difficulty of implementation and standardization of mechanical experiments with machines that are able to monitor and supervise their implementation throughout the trial, to obtain reliable properties and subsidies providing material correct modeling.

This work aimed to describe the training and development (T&D) process in a continuous way, existing in a national cosmetics company, as well as identified in the organization the need for training, determining its stages and performing a comparative analysis before and after training , describing the research participants' perception of training. The present research was characterized as exploratory and descriptive case study. The instrument for data collection was a semi-structured questionnaire, applied to ten employees on the company's front line.

Coral Sun is an exotic invasive species that has spread over three thousand kilometers of the Brazilian coast, representing a threat to the ecosystem. Some of these bio invasive species are embedded in oil platforms on the Brazilian coast. The present study sought to evaluate the advantages and disadvantages of removing the Coral Sun in marine oil units in Brazilian waters by means of two procedures: the first using a team of divers and the second, an ROV, more specifically, a Roving Bat.

A poluição das águas é um problema grave principalmente nos grandes centros urbanos. No Brasil o caso é agravado pela falta de saneamento básico na maior parte das cidades o que influencia diretamente no tipo de tratamento de água para abastecimento que deve ser executado. Dessa forma, o monitoramento da qualidade da água que é fornecida para as populações é de extrema importância considerando os riscos que uma água contaminada por patógenos ou por outros poluentes de natureza química ou física podem trazer.

The growing demand for environmental licensing processes in special municipalities, as a result of the process of decentralization of intensified competences in recent years, generates a series of environmental requirements that, in these cases, do not observe some technical or legal aspects of great importance, including all these licenses subject to administrative and / or judicial penalties and nullities.

Este artigo tem como objetivo avaliar á eficiência ambiental dinâmica dos campos de petróleo das bacias costeiras brasileiras, considerando os anos de 2014, 2015 e 2016, por meio da Análise Envoltória de Dados (DEA) e validada pela regressão logística. Os dados foram disponibilizados pela ANP (Agência Nacional de Petróleo) em seu sítio eletrônico perfazendo um total de 67 campos pertencentes às bacias de Alagoas, Camamu, Espírito Santo, Potiguar e Sergipe.

The rapid developments in transport, communication, technology and economy during the last fifty years have unavoidably led tourism in an uptrend. More and more people are becoming travelers and “collectors of experiences”, engaging in a continuous mobility that has both positive and negative effects. The realization that tourism can relegate the place of destination both socially and environmentally, has resulted in the conception of the term of Sustainable Tourism, as an activity respecting the social fabric and promoting socially and environmentally friendly touristic practices.

The combination of tools and the possibility of arranging mechanisms that prove to be sustainable and aimed at meeting a certain environmentally correct demand is a challenge today, as it depends on the perception of professionals in charge of implementing changes in conventional systems. Ensuring that the precepts of energy production are shaped bringing more efficiency, also implies the impact on the environment, be it small, medium or large, certainly, that actions that reduce this impact corroborate for new conducts and other applications.

This paper aims to present a study carried out in a municipal school on the city of Manaus, in the state of Amazonas (Brazil). The proposal was to assess students' perception of the concepts related to education and sustainability and how the circular economy can be boosted in society through consistent educational policies. The methodology consisted of the application of a questionnaire to students of a public school, in order to assess their perception about the environmental theme and the promotion of circular actions.

This work focused on the development of a methodological proposal based on the principles and foundations of Unplugged Computing (CD), in order to develop playful activities related to the introduction of computer science without using the computer and outdoors. The proposal was applied to two different classes, one from the 9th grade of elementary school at Escola Comunitária de Augustinópolis (ESCA) and the other from the 2nd year of high school at Colégio Estadual Manoel Vicente de Souza (CEMVS), both in Augustinópolis-TO.
