The process of steel production emits a large quantity of greenhouse gases, specifically carbon dioxide (CO2), and the reduction of such emissions is one of the main challenges for the industry in the 21st. Century. To quantify these emissions, the Worldsteel Association (association of the 170 large steel manufacturers of the world) published a methodology (CO2 Emission Data Collection) for calculation and comparison of CO2 emissions among its members. After that, in 2010, this methodology became an ISO (International Organization for Standardization) norm. Today, the calculation of the CO2 emissions in steel making companies follow the ISO 14404-1 for units with blast furnaces and the ISO 14404-2 for units with electric furnaces. In the last years, new technologies were and continue to be developed for the steel making sector aiming at energetic improvements and greenhouse gas reductions (mainly CO2) by the several processes involved in the production of steel. This work had the objective of producing a tool to calculate the CO2 emissions for the steel making sector. An Excel spreadsheet was developed to calculate the emission intensities of CO2 of a steel plant, the Usina Presidente Vargas, of the Companhia Siderúrgica Nacional (CSN). The spreadsheet furnishes results of CO2 emissions and energetic fluxes, and simulates the benefits that some of the new technologies can give to the company. The spreadsheet calculates the emissions in two ways: a) based on the carbon fluxes that enter the unit, and b) based on the emissions of each specific process within the unit (coking, sinterization, blast furnace, among others)

The education research guidelines have shown the important contribution of the investigations that focus on analysis of the discursive dimension of teaching and learning of Science in actual classroom. An interesting proposal to analyze the effectiveness of an educational activity is to assess the potential of investigative activities in the development of argumentation in science classes. Several studies have taken into account the use of argument in the classroom as a way to provide students with new ways to know the science. Argument refers to the process of associating components that play a central role in the construction of explanations, models and theories. In order to investigate the potential of these activities took place the application of investigative activities with third-year high school students, recorded in audio and video, focusing on the development of the argument. The search, conducted ranks as a qualitative research with characteristics of a case study. The arguments collected during the activities contained the students' conceptions about the concepts discussed and all were recorded in audio and video. With the encouragement of the argument by the investigative activity we evaluate the learning experienced by the speech of students. It may be noted that students have appropriated the concept of oxidation involving electron transfer, thus the activity reached the goal, so that was planned, making it effective for the introduction of electrochemical concepts

A necessidade de fazer com que haja um aumento no consumo de hortaliças se faz crescente no mundo inteiro, isso porque esta é uma fonte rica em micronutrientes e macronutrientes, além de não agregar muito valor calórico na dieta e ser um alimento acessível para todas as classes econômicas. Entretanto, no Brasil, é verificado que a porcentagem da população que consome diariamente o recomendado de hortaliças e frutas ainda não atingiu o ideal para que se possa obter os benefícios trazidos do consumo, como a prevenção de algumas doenças não transmissíveis, através da dieta. Por isso, a necessidade de se estudar maneiras diferentes de cozimento das hortaliças, para que se torne possível preparar os vegetais de maneiras diferentes e torná-los mais atrativos, garantindo a melhor forma de fazê-los, para que se escolha o tratamento que melhor conserva o conteúdo de compostos bioativos. Para esse estudo foram considerados dois vegetais de grande importância, o espinafre (SpinaciaoleraceaL.) e a chicória (ChicoriumintybusL.), que foram submetidos a quatro tratamentos de cozimentos dististintos, a 100°C, no vapor, no microondas e no óleo, para cada tratamento foi avaliado parâmetros de cor, análise de sólidos solúveis totais, acidez titulável, determinação de ácido ascórbico, determinação de fenólicos e flavonoides totais, avaliação da atividade sequestrante de radicais livres (DPPH e ABTS) e carotenoides. Os resultados obtidos foram bastante diversificados, ou seja, para cada teste desenvolvido houve uma retenção maior do composto bioativo estudado em determinado cozimento preparado, entretanto o tratamento realizado a 100°C foi o tratamento que obteve menor retenção dos compostos bioativos entre os testes realizados.

Given the high competitiveness in the construction industry, businesses became necessary in a management which reduce costs and delivery times, and is fundamental to running a compatible planning with the magnitude of each work order is the same make feasible the executor. When it comes to planning, one is including both the physical planning of the work, time and duration of the events, as well as the preparation of the cost thereof. There are numerous ways to run the management of works, then it is necessary, in most cases, the planning experience, in previous works, the engineer in charge, because with it he should know what strategy to take the work skirt as planned and designed. For a complete and efficient management, an initial study hard to prepare the physical and financial planning it is necessary, in order to make it real and consistent throughout the execution of the work. It is necessary also a hard monitoring of both the physical and the financial schedule in order to what was initially planned to be completed as close as possible. This paper shows a case study which uses some ways to the management be held with the course of planning, medium and short term, as well as the preparation of the initial budget of the work. Will also be presented as is performed physical planning of a real estate work

Radiopharmaceuticals are substances marked with radionuclides that can be used for detection and treatment of cancer, infections and inflammatory diseases. They emit several types of radiation through different decay routes, each radioisotope with its specific properties and uses. They can usually be produced from several different materials, by bombardment with particle beams in a nuclear research reactor or cyclotron, depending on their characteristics. Brazil has four public institutions which produce - or import - and distribute radiopharmaceuticals to hospitals and clinics throughout its territory. The largest such institution, Ipen, distributes 97% of radiopharmaceuticals used in the country. Some radiopharmaceuticals decay very quickly, meaning they must be produced and quickly administered to the patient in the same location, presenting a logistical challenge. Nuclear medicine in Brazil is a promising field and has been steadily growing, although rigid laws and a lack of qualified work force hinder Research and Development efforts for new radiopharmaceuticals. The construction of a new nuclear research reactor, in 2016, should generate self-sufficiency and economy in radiopharmaceutical production and avoid a future crisis in the supply of technetium-99m, the most important radioisotope, used in over 80% of procedures with radiopharmaceuticals.

This article aims to show the interdependence between teaching practice and the construction of body hexis of Physical Education teachers and its consequences at schools. It can be observed by the social workers that teach it in a elementary school in the city of Araraquara- -SP. It was established, as basic assumption of this issue, that the social construction of body hexis of Physical Education teachers is a process in constant evolution, because it is the result of the life story with interventions from the social context in which the learner lives. The hexis is the dimension that allows the internalization of the consequences of social practices, and also its body exteriorization, through the way of speaking, gesturing, looking, walking, head posture, faces, ways of sitting, to handle instruments, more and more associated with the voice sound of social workers. Children are particularly attentive, in all societies, to these gestures and postures in which they express themselves in their eyes, anything that features an adult. Finally, it understands the importance of the body hexis in the learning process specifically in school physical education. This practice will incite important behavioral changes in their residence within the school and possibly in a higher education.

D’après Greimas (2002), le sens se concrétise par le changement de rythme ou par une oscillation construite dans la linéarité du langage. L’étrange et l’imprévu, considérés comme des événements qui troublent la pratique habituelle d’une vie dans son parcours, entrent ainsi dans le domaine d’études de la sémiotique française. Le sujet a été discuté plus tard par Claude Zilberberg, avec la venue de la sémiotique tensive, pour qui l’appréhension d’un événement se donne dans le survenir. De plus, selon les observations de Greimas, pour la sémiotique, une forme de vie caractérise des manières par lesquelles les individus ressentent et expriment leur compréhension de l’existence à travers des façons de faire, d’être, d’organiser l’espace dans lequel ils vivent, etc. Devant ces présuppositions théoriques, nous analysons le reportage “Eu pego mas não me apego”, publié dans Atrevida, une revue dirigée vers un public féminin dont la tranche d’âge est de 15 à 19 ans, et nous discutons la manière dont l’énonciateur a configuré le simulacre de l’acteur “ado branchée”. Il en ressort que l’énonciateur a utilisé des stratégies verbales et qu’il met ainsi en discours l’idée d’un comportement qui parait transgresseur au niveau de la manifestation, ce que l’on peut caractériser comme un événement. Cependant, on notera la présence de marques textuelles implicites qui rendent possible un discours qui se réfère au comportement féminin traditionnel et qui caractérise une routine.

In order to ensure the teaching and learning process of written and spoken language, the state government of São Paulo established as the official curriculum Read and Write Program (2007) and EMAI (2012). In municipal elementary schools in Bauru SP, since 2013, went into action the Common curriculum, targeting a unified curriculum. The curriculum has a wide range of definitions, which vary according to the conception of the authors, as well as its practice can occur of different ways resulting from the worldview and teacher's work. So, this study aimed to analyze the relationship between the curriculum of state and municipal schools in Bauru regarding its articulation with the use of technology in the early years of elementary school, opposing proposal curriculum and teaching practice. For this, was necessary check the view of teachers on this process, because they are responsible for putting the curriculum in action and link it with the use of technology. Several authors report that the use of technology in education to provide qualitative advances in school learning, thereby we asked whether there is a joint in the daily life of state and municipal schools, through the existing curriculum. To answer these and other questions in this work, we realized a qualitative empirical research base that used as an instrument of data collection: literature review, documentary, interview and questionnaire with nine teachers from public schools in the city Bauru, on which we identified that there curricular flexibility to articulate the use of technologies. However, there are also many challenges and opportunities related to public policies and training of teachers to cope with the demands of the digital age

In our analysis of Antonil, author of Cultura e opulência do Brasil, we oppose to the historiography that analyses him as a writer who examines Brazilian society of the late seventeenth and early eighteenth centuries, sometimes from a religious perspective, others from the economy perspective. Thus, the historiography sometimes explains him as an author who has a religious vision of society, others as an author who would have an economic view of it. In our viewpoint, both ways to consider him fail for being extreme. To comprehend him, it is necessary to understand him from the issues he has dealt with and how he dealt with them. Only then we can reconcile the religious and economic aspects of his worldview.
