Knowing the physiological potential of seeds under certain conditions and storage periods is essential to ensure their availability with adequate quality, as well as information on more productive genotypes. Thus, this work was carried out to analyze the quality of seeds of different cowpea genotypes stored in bags of multifolium paper in a cold chamber during a period of 48 months and subsequently to evaluate the yield potential in the field. For this, two studies were conducted, both at the Universidade Estadual do Sudoeste da Bahia (UESB), campus of Vitória da Conquista, Bahia, Brazil. The first stage was carried out in the laboratory with seed quality evaluation and the second stage was carried out in the field with evaluation of phytotechnical parameters of the genotypes of plants originated from seeds stored. The treatments consisted of eight genotypes of cowpea, of which five were cultivars (BRS Guariba, BRS Novaera, BRS Tumucumaque, BRS Itaim, BRS Cauamé) and three lines (MNC04-769F-49, MNC04-769F-62, MNC04-795F-159). The main conclusions of both experiments were that the seeds conserved in a cold chamber for 48 months did not suffer depreciation in quality, vigor and germination capacity, as well as the plants originated from these seeds also showed satisfactory yield, especially the line MNC04-769F-62.

Parasitology and Medical Entomology teachers have identified difficulties on teaching-learning processes and opportunities to elaborate new teaching materials. Thus, we had engaged in interdisciplinary efforts between Biology and Informatics to develop teaching materials in paper and in digital format, accessed through computer and internet: a virtual atlas to support practical classes; a virtual identification key to guide and support students during taxonomic identification; and an educational game to promote students' curiosity while they have fun. Grounded in Semiotic and Communication theory, we discuss aspects of some medias used in the production of teaching materials that influence their diffusion and knowledge access. In particular, we analyze what can be explored in the migration from paper to digital world (computer + internet). We conclude with reflections about our interdisciplinary collaboration, ways to appropriate the potential of digital technologies in education, and access problems to digital technology.

The objective of this paper is to describe a business model of a multidisciplinary junior enterprise that offers products and services. It starts from the identification that there are no multidisciplinary junior enterprises in the Federal District with courses in different knowledge areas; junior enterprises offer only services; there are no examples in the literature of how organizations that work with different levels of education can benefit from the performance of students from technical courses in a junior enterprise without being junior entrepreneurs. The description was based on the logic of the business model. The most important choices in the business model of Olaria Junior Enterprise were: institutional support via coproduction; multidisciplinarity; offer of products and services; development of partnerships; participation of students of technical courses in the junior enterprise; competitive prices and sustainable development. The paper seeks to contribute to the process of implementing junior enterprises in educational organizations. [ABSTRACT FROM AUTHOR]

The transformation of the rationalities that underlie the way in which the teaching-learning process is carried out in universities has become a challenge for pedagogical models in higher education. This challenge becomes greater in the case of the areas of Science and Engineering where a conservative pedagogical practice has prevailed. For this reason, it is necessary to search for alternatives to traditional teaching in which the development of other capacities and skills in students that contribute to the formation of permanent and autonomous learners is incorporated. This paper reflects on this situation and presents the results of the implementation of a strategy to promote critical thinking skills with first-year Science and Engineering students from a Peruvian university, in the context of a General Chemistry course.

The vegetable loofah (Luffa cylindrica) has multiple industrial aptitudes and its interaction with allelopathic substances of other species is important for the definition of management strategies and also in the search for control alternatives for invaders in organic crops. The objective of this research was to evaluate the effect of the crude aqueous extract of carqueja (Baccharis articulata) on the germination and growth of seedlings of vegetable loofah. The experimental design used was completely randomized, with four replications and the treatments were composed by the concentrations of carqueja extract (zero, 25, 50, 75 and 100 g L-1 ). Seed germination was tested by the paper roll method with 25 seeds properly spaced over each germination paper. The evaluations were performed at four and fourteen days after the test was installed. The percentage of abnormal seedlings, germination and vigor, length of shoot and roots, dry weight of cotyledons, hypocotyl and roots were evaluated. There was a negative allelopathic effect of the aqueous crude extract from the shoot dry of carqueja plants on germination and vigor and on the growth of seedlings of vegetable loofah.

This paper aimed to evaluate the public policy of dry law through the perception of military police officers of a State of the Federation, taking into account social, legal and financial criteria intrinsic to this policy. Methodologically, a questionnaire had been made available through an instant messaging application for smartphones, a group formed by only officers, from the most varied stations. A descriptive research with a quantitative approach was carried out, giving a focus to the numerical representativeness by means of percentages. The main results show the alignment of the opinions of the research collaborators with the objectives that the dry law seeks to achieve, translating into improvements for society, but with the need to involve more actors in the partnership of conducting the policy. It is concluded that the population knows the limits imposed by the law, there is still consumption of alcoholic beverages by drivers of vehicles, who know the heavy penalties imposed on transgressors and that, even with the reduction of accidents and behavior change with the alcohol-steering relationship, initiatives within the dry law must remain and progress.

This paper aims to expose the implications and links between teaching, curriculum, and didactics in early childhood education (ECE), based on the theoretical and methodological principles of historical-critical pedagogy. It is based on the premise that the educational process is an intentional act developed within social practice and, therefore, that ECE needs to advance in its curricular proposals: from children's immediate and daily experiences to the right of systematized access to scientific, philosophical, and artistic knowledge historically produced by humanity. The teaching has substantial implications for this achievement, since it is the teachers who direct the educational process, and the didactic organization, in the light of historical-critical pedagogy, is also revealed as a possibility in the first stage of basic education, presenting itself as a decisive contribution to EI.

Resting on bibliographic reference, this paper focuses on the subject of the Historical-Critical Pedagogy (PHC). It aims to discuss about PHC, taking elements from its historical and conceptual path brought about from the ideas of intellectual and activist Dermeval Saviani, since the late 1970s, up to the achievement of its collective character, in a movement that builds a critical pedagogical theory of the relationship schoolsociety. Historical, philosophical, psychological, economical, socio-political and methodological aspects constitutive of this anti-establishment theory are approached, as a possibility for the educational work to be developed in public schools, to answer the working class' needs. It's a necessary path to be followed by education professionals. It is a theory that has as one of its central assumptions the defense of classic knowledge domains, the curriculum as a fighting tool against the weapons deployed by the ruling classes. The PHC thus upholds a project of education and school. [ABSTRACT FROM AUTHOR]

The vocation and the teacher identity has been an object of varied discussions with which they are invoked to develop as inheritance or as a resulte of a process into building. For ende, this papers proposes to examine the relation between autobiographical narrative, vocation and reconfiguration of the teacher identity, characterizing these existentially narrated phenomena. The methodology fenomenological interpretive favored this research, which was done on the base of an analytical re-reading to fragments extracted from a previous research, across the exercise of reintepretation of this data trying to show elements that were using as support to the present exposition. The product of this reintepretation admits that the vocation and the identity of the teacher are dimensions dynamically constructed and in permanent process of reconfiguration, favored by the narrative life experiences and provoked in his own practice.

Rocks and industrial minerals are raw materials employed in the production of a wide variety of products, used by modern society. The same mineral or industrial rock can have several applications, depending on their physical, mineralogical and chemical characteristics. The present study had as its objective, the technological characterization of a metapyroxenite sample, belonging to the Córrego dos Boiadeiros body in the Quadrilátero Ferrífero, MG (Brazil) in order to verify its possible industrial applications. For this research study, X-ray fluorescence chemical analyzes were performed, which determined the following oxides: 0.06% TiO2, 8.2% Fe2O3, 24.1% MgO, 2.1% Al2O3, 48.7% SiO2 and 1.8% CaO. In the mineralogical characterization by X-ray diffraction, optical microscopy, SEM / EDS and thermogravimetry, the following minerals were identified: antigorite, chlorite, chromite, ilmenite, magnetite, rutile, talc and tremolite. For the preliminary concentration tests, the material used (-147μm) presented 32% of the particles in the fraction -37μm with d50 in 74μm. The 3575 Gauss magnetic field and the particle size fraction -74μm generated a mass recovery of 96.4% and a whiteness of 61.9% for the non-magnetic product. Although no talc enriched products were generated by preliminary magnetic separation tests, the non-magnetic products presented specifications for the following applications: paper (wallpaper and packing), insecticide and fertilizers.

In Brazil, the development of the dam engineering can be directly correlated to social and economic progress. Although fundamental, a dam construction and operation invariably involve some level of risk, which must be managed through different mechanisms and tools governed by appropriate laws. This paper aims to scrutinize the data contained in National Water Agency (ANA) reports, published annually following institution of the National Dam Safety Policy (PNSB), pertinent to dams accidents and incidents. This information was cataloged and analyzed in order to identify trends associated to types of accidents and incidents, dam component materials and entrepreneurs involved, as well as the disparities between data available from the different regions of Brazil. There is a lack of basic data in numerous reports, hindering more in-depth statistical analyses. The recurrence of this deficit was observed as well as the need to improve the methodologies used to apply the PNSB guidelines. [ABSTRACT FROM AUTHOR]

Nowadays, engineering courses spend a lot of time on theoretical studies. From these contents, the rest of the time aims to practical issues and applications of the investigated concepts. In this way, one of the teaching methodologies that introduces a practical contextualization to the students consists of using didactical tools for conducting experiments, such as benches and equipment, which are key elements in the teaching-learning process. This approach is mainly applied to content related to process control, such as dynamic systems, nonlinear systems, and systems with disturbances, which are presented in engineering courses that encompass control and automation. Due to the importance of the didactical tools for understanding contents formerly approached theoretically, this paper presents the development of two didactical tools to complement the control system studying: an aeropendulum and a Furuta pendulum. In general, inverted pendulum systems offer challenges in the modeling and control design steps. Thus, the pendulums presented in this article are important tools for teaching content related to control systems. Once the prototypes of the proposed systems are validated through control experiments, they will be used as teaching tools in curriculum components in engineering courses, for example, in disciplines of control systems, feedback systems, multivariable control, and nonlinear control.

The number of Mining Engineering courses has increased in Brazil since 2004, resulting in a significant rise in the number of graduates. However, such growth was not followed by an equivalent rise in the number of applications for professional registration as a Mining Engineer with the Regional Engineering Councils, which might indicate a shortage of professional opportunities in the marketplace. This paper addresses the current labor market scenario for mining engineers in Brazil, taking sources of formal employment data as a basis: the Labor Ministry's CAGED and RAIS employee data systems. It was found that there has been a significant asymmetry between the number of graduates and the number of mining engineers formally registered in the country in recent years. Moreover, the number of mining engineers' dismissals exceeds the hiring figures as of 2012, in contrast with the previous expansion forecasts in this industry, elaborated in 2010 and 2014, based on which new Mining Engineering courses had been opened.

The paper analyzes the perception and commercialization strategies of production adopted by the workers of the street fair Venda Nova do Imigrante before the containment measures of Covid-19 by the city government. With human vulnerability to the pandemic, the city has preventively suspended the local operation of the street fair, opening the delivery modality, enabling continuity of commercialization with adequacy, as well as the use of public policy tickets to promote family farming. In the methodology, the qualitative approach was prioritized, with academic and official references to the thematic understanding and the characterization of the cutout. After prior dialogue with representatives of the street fair Administration, it was held the contact with the survey subjects (members of the Street Fair Association) to forward questions and get answers by mobile application. The protagonism and the organization capacity of the market owners were revealed in the flexible return of the Feira-Livre, although the individual conditions of commercialization provoke the cooling of the community.

This paper discusses the pandemic of COVID-19 as an integral phenomenon, which is formed not only by the virus in itself but by the whole range of relationships and activities emerging from this phenomenon. The object of analysis is Science Education, especially how it has been developing throughout the pandemic situation. In this sense, we point out the need to understand the current pandemic, taking into account not only the virus's microfauna but the pandemic as a social issue. In this scenario, in educational terms, emerged what was called "remote emergency activity" emerged and even with the use of technology it is necessary to highlight that no technology, however best and most developed, will supply the work of a teacher, or better, contact and human sense cannot be replaced. Concerning educational activities in science, they must go beyond a mere "transmission of content", that is, an Education in Science for the development of concrete possibilities of human emancipation, through the Discussions About Science. Finally, we consider that we will not rebuilding human culture from the beginning in a post-pandemic world, but continue to develop movements of resistance and struggles engaged in transformation based on Science Education attentive social justice.

This paper presents the calculation of residual stresses present in cylindrical pressure vessels subjected to weld repairs using the ASME PCC-2-2015 via numerical multiphysical thermal structural analysis using the finite element method. The methods of analysis of residual stress by numerical analysis are increasingly part of the dynamics of structural integrity in equipment such as pressure vessels, flanges, heat exchangers, in addition to observing the behavior of these stresses in the thermally affected areas due to welding processes. In welding repair, the sleeve is attached to the pressure vessel through two longitudinal welds and two transverse welds. The modeling of the pressure vessel, repair and welding were carried out according to the aforementioned standard. The welding parameters were adopted with what happens in practice, and with that the temperature distribution and heat flow were obtained. The objectives were to analyze the longitudinal, tangential and residual stresses in the regions of the weld, pressure vessel and repair during the welding period, and to verify the behavior of these stresses after the cooling period. This work shows that numerical analysis can be used efficiently and objectively in situations of control and knowledge of the structural integrity of equipment. [ABSTRACT FROM AUTHOR]

This paper aims to analyze the use of the information system for control of leaves of the Federal University of Minas Gerais, through the integration of TAM (Technology Acceptance Model) and TTF (Task Technology Fit) models, under the perception of its users who use this system. These models are used to explain the acceptance of technologies by its users. This is a quantitative and descriptive research through a survey and as a population the employees of the sectors that participate directly in the removal process. The integrative model was tested by eight hypotheses, five of which were supported. The results indicate that the integrative model is able to contribute to the management of information systems through the integrative model relationships through which high evaluations of the experience of use, perceived utility and ease of use contribute to a higher level of use of new information and current information systems.

The effective improvement of the teaching-learning process occurs through the intervention of the teacher and the continuous improvement of his pedagogical practice in initial and continuing education actions. Thus, the school environment is an environment conducive to research and investigation of the potential of different methodologies. In this sense, Potentially Meaningful Teaching Unit (PMTUS) - theoretically grounded teaching sequences - are focused on Meaningful Learning, since they can stimulate applied research in teaching, which is directed directly to the classroom. In this paper, we present results of the analysis of the use of the PMTUS, presented through a pedagogical workshop, by Chemistry graduates, aiming to evaluate the extent to which they can see the strategy as viable and interesting to approach chemical contents. We adopted in this work the quantitative research, using the Likert scale and qualitative, from the active research, in the form of action research. Quantitative data were processed according to classical statistics, using as centrality measures the arithmetic mean and standard deviation. As for the qualitative data, they were built from the Bardin Content Analysis. From the evaluation of the action, it was possible to conclude that the students perceived the PMTUS as interesting to be used in their classes. However, they are considered unviable due to aspects related to the time allocated to their preparation. [ABSTRACT FROM AUTHOR]

Biogas has risen, as a renewable technology promising to convert litter organic substance into energy; among its components, in terms of energy, methane is the most important chemical component, particularly for the combustion process in vehicular engines. The use of methane derived from landfill organic matter waste to replace fossil fuel minimizes environmental impact by providing a significant reduction in greenhouse gas emissions. This paper reviews the environmental, social and economic aspects of biogas as a source of energy, the process of producing this renewable energy, and the potential of biogas in producing energy for internal combustion engines. Studies have shown that biogas is a driver for sustainable regional and local development, since energy consumers themselves, becoming producers, can product biogas and be better able to control inputs for their production activities. For engine applications, it has been found that by adding a certain proportion of H2 to biogas, the combustion properties can be improved. [ABSTRACT FROM AUTHOR]

In this paper, we analyze the design and implementation of rubrics assessment (Brookhart, 2013, Howell, 2014) in the undergraduation course of Numerical Analysis. We use a qualitative methodology, guided by the strategy of the critical friend (Cornejo, 2016; Sandretto, 2016; Schuck & Russell, 2016; Butler et al., 2011). As a result, we developed and implemented four rubrics. We present them and their implications of situated nature; then we discuss in what proportion they are valid to meet the demands of the professor as well as reflect on the assessment process in order to qualify it. As a conclusion, we validate the reasoned reflection and the action based on reflection to conduct (re)configurations in the micro plane (the classroom) and with repercussions in the medium and long term. Also, we contribute to the development of research using the strategy of critical friends, as a resource for continuing education of Higher Education professors. [ABSTRACT FROM AUTHOR]

The paper intends to examine the figure of "exile" and its contributions to the historian's craft in the modern regime of historicity. Firstly, from Walter Benjamin's approaches of Charles Baudelaire and Paris in the 19th century, it analyzes the qualities and the challenges of this historic time to the historiography. In a second time, the paper works the category of "exile" as inherent to the political and cultural processes of the Black Atlantic, as well as to the distinctive narratives produced by the African Diaspora in the modernity-coloniality. Thereby, it is expected that the idea of "exile", anchored in the experience of people of African descent throughout the Atlantic world, provides an instrumental framework to think the history and the historian in contemporary.

In prestressed concrete, due to the application of the prestressing force, the anchorages zones are subjected to high stresses. Along a stretch, called anchorage zone, the distribution of these stresses is not uniform, with transversal stress acting in the structural element. To resist the transverse stresses, it is necessary to adopt complementary reinforcement, called anchorage zone reinforcement. In this context, this paper aimed to investigate the behavior and distribution of stresses along the regularization length of prestressed elements, numerically evaluating in the Abaqus® software the influence and importance of anchorage zone reinforcement on such elements. For this purpose, four numerical models were simulated, VE, VEF-3, VEF-4 and VEF-5, with the same area of longitudinal and transversal reinforcement, differing in the fact that the VEF-3, VEF-4 and VEF-5 have, respectively, 3, 4 and 5 additional stirrups at each end of the beam. It was found that the insertion of the additional stirrups did not promote significant changes in the compression failure in the anchorage region, however it did promote relevant reductions in the failure in the traction. In addition, in the VE model, the value of the stress in the armature reached the yield strength of the steel, while in the models VEF-3, VEF-4 and VEF-5 the stresses reduced 19.48%, 56.58% and 57.96 % in relation to VE. This fact highlights the importance of anchorage zone reinforcement to assegurate the safety of unbonded post-tensioned beams. [ABSTRACT FROM AUTHOR]

Microemulsion-based drilling fluids are a new technology that aims to substitute water and oil-based drilling fluid, for featuring high lubricity, stability, low toxicity, low cost and less fluid loss. This paper studies the viscosifying action of xanthan gum and bentonite in a microemulsion-based drilling fluid, composed by an aqueous solution of glycerin, vegetable oil and a nonionic surfactant, through rheological tests. From the results, it could be concluded that the xanthan gum has a higher viscosifying action, since the drilling fluid added with a smaller amount of this biopolymer presented a higher apparent and plastic viscosity, gel strength and shear limit. The two viscosifiers attributed pseudoplasticity to the drilling fluids and the rheological model that better adjusted to the presented behaviors was the Herschel-Bulkley model.

Environmental management practices are needed across organizations from different sizes and economic sectors. This includes the education institutions, which develop polluting activities, such as physical-chemical laboratories, which are used in teaching, research and extension activities. An understanding of environmental aspects and establishment of environmental control measures across the laboratory are crucial for environmental management. The assessment of the environmental aspect and impact contributes to this performance. Thus, this paper aims to assess the environmental aspect and impact of a physical-chemical laboratory of the federal Institute of Education, Science and Technology, campus Natal, and to propose practices to control them. For that, a case study was carried out focusing on the assessment of environmental aspect and impact through the application of the Failure Mode and Effects Analysis (FMEA) method. FMEA takes into considerations criteria like severity, probability and detection. The significant environmental aspects identified were associated with the outputs of laboratory activities, such as hazardous solid waste, non-hazardous effluent and hazardous effluent. Practices to control the significant environmental aspects were proposed, considering the needs, the organizational structure and the financial resources. Overall, key enabler for the implementation of the practices was the low cost of implementation, leading to a better control of the environmental aspect. [ABSTRACT FROM AUTHOR]

The study and use of numerical simulation in Reservoir Engineering arises from the need to obtain a prediction of the behavior of an oil field during production. This projection is essential and it influences on choosing the best production strategy, which will be able to extract the greatest amount of oil and achieve better performance. In this context, this paper aims to use numerical simulation as a tool to predict and analyze the performance of various field cases studies for a conventional oil reservoir model subjected to secondary oil recovery techniques, such as water injection and immiscible gas injection. Water injection is a well-known technique and it is widely used in oil industry. Furthermore, both techniques aim to displace the oil in the reservoir to surface and no chemical interaction is involved between the injected fluid and the oil. The numerical simulation of flow in this paper was performed with the software in finite differences, IMEX - Computer Modelling Group (CMG) and the analysis of results was accomplished by comparing the recovery factor of the field, accumulated oil production and final oil saturation obtained for each field case study. To define the physical model, it was used the properties observed in the East Unity field, in Muglad Basin-Africa. [ABSTRACT FROM AUTHOR]

Despite the relevance, discussions and dissemination of information, the execution of measures to cope with desertification have barely been implemented. Therefore, this paper aims to present a synthesis of information on the environmental aspects of the areas susceptible to desertification in the Brazilian semi-arid region and to present the socio-environmental characteristics most directly related to desertification in the Seridó do Rio Grande do Norte and Paraíba. For that, Where it was consulted books, institutional documents, specialized periodicals, scientific articles and access to databases, through expressions in Portuguese that related to desertification, areas susceptible to desertification, center of desertification and desertification center of Seridó. It was found that there are 1,340,000 km² of ASD in Brazil, which occur mostly in the semiarid region. In the ASD, prevailing rainfall indices below 800 mm, with high potential evapotranspiration. The soils, which have long been used by humans and are moderately to highly sensitive to erosion, have the following levels of degradation: 40.80% (moderate), 27.68% (high) and 5.86% (very high). The Caatinga is the predominate biome, and 46.4% of this territory has been influenced by humans. In Seridó RN / PB, as implications of the predominant economic characteristics, characterized by intense extraction of firewood, for use in the ceramist industry and in small urban industries, and in increasing use of previously agricultural land for livestock production, are forging a picture of environmental degradation, requiring, according to their natural characteristics, a model of economic use appropriate to semi-arid conditions.

The glass microspheres are abrasive materials of fine particles, commonly used in industrial activities for cleaning and polishing of metal parts. After your use, generally, are arranged in landfills of industrial waste. This paper proposes an alternative to reuse this material performing an evaluation of mechanical performance of a basalt residual soil after the addition of different glass microspheres waste contents. Initially, were carried out characterization tests of the glass microspheres and the mixtures were submitted to compaction, direct shear and California Bearing Ratio (CBR) tests. It was noted that the residue does not act in soil improvement, because, in general, the resistance of mixtures were inferior to determined for soil pure and waste pure. However, mixtures showed higher internal friction angles than pure soil, being the highest value displayed by mixing with waste content of 20%.

Due an increasingly competitive market and companies seeking for free competition, a concern always present is cost reduction. This concern, nowadays, involves the environmental as well, and it is necessary to think about a reduction in the use of natural resources. Thus, structural systems must be designed so expectations such these can be satisfied, as long as they follow design criteria of building standards. The present paper aims to apply the concepts of optimization in the design of reinforced concrete beams with rectangular section. It also introduces a literature review of beam design and general concepts of optimization. Therefore, it is proposed the application of classic Newton method with exterior penalty to minimize the objective function (OF) of costs. The function is described by design criteria found in NBR 6118 (ABNT, 2014). Thus, it was verified the validation of calculation routine proposed (WJM_otimiza) and it was also verified the application of that routine in real problems. For the analysed cases, the beam cost varied between R$ 86,64 to R$ 453,24. [ABSTRACT FROM AUTHOR]

The present paper discusses the insertion of Social Assistants in Public Health Policy under a perspective the expansion of social rights, since these profesionals work in prevention, health's promotion and regular improvements in public Health System in relation to access and extension rights health desk. In this way, the general objective is to analyze as the insertion of social assistants in health in the framework of the Health Reform Movement even an arrival of Neoliberalism in 90s. In the literature review have been studied authors who discuss the theme Social and Health Service as: Bravo (2006), Code of Ethics/a Social Worker (1993), Minayo (1994) and Parameters paragraph Practice of Social Workers in Health Policy (2013), besides documentary revision of the laws relating to health such as the Constitution of the Federative Republic of Brazil (1988) and Law 8.080. A qualitative approach was used from the method of the narrative analysis, which will address the major landmarks that customize the inclusion of social workers in health, focusing mainly on health reform, federal council of social assistant resolution and the arrival of Neoliberalism. The resolution legitimized the performance of these professionals in the field of health, being currently the area that employs more social workers in Brazil. Finally, the study found that the social worker has his activities often considered as irrelevant, this fact is given even greater importance to the curative practices, minimizing educational activities, mobilization and communication in health together with the various professionals in the field of health.

This paper aims to show how the formation of a layer of organic intellectuals linked to Industrial Psychology in the early twentieth century and their respective economic and ideological class functions. Therefore, was analyzed the main works of some of the most important figures that had a great influence on the advent of Industrial Psychology in the period in question, as well as commentators of their works. The action of this group was analyzed from theoretical categories such as social class, social relations of production and organic intellectuals. Given the research done, it was possible to observe how the Industrial Psychologists and its related had a strategic importance in the recomposition of the productive forces of the American industrial capitalism of the beginning of the twentieth century and whose theoretical and ideological developments continue to influence the formation of managerial staff until today.

Apatite is the most common phosphate mineral, in addition to being a non-renewable resource it is the only economically viable source of phosphorus for fertilizers and phosphate chemicals. Chile in 2016 produced 6,205 tons of phosphoric resource and in the same year it imported 230,738 tons. This makes it necessary to study technology to concentrate the phosphate minerals present in iron tailings, promoting productive diversification and decreasing the volumes of environmental liabilities. The effectiveness of a collector was analyzed in a tailings generated from the magnetic concentration of iron, which contains quartz, iron oxides, feldspar, carbonates and amphiboles. These phosphate minerals were concentrated by flotation, using sodium oleate and a synthetic reagent as a collector. This paper presents the results obtained with the AkzoNobel collector, called Atrac 2600 and shows that under conditions of flotation of 500 g/t of collector, 400 g/t of Na2SiO3 as disperser of gangue, a law of 20.1 is reached % of P2O5 with a recovery of 88.4%. These results obtained when compared with those of sodium oleate present better metallurgical results; it would allow it to portray the large volumes of iron tailings, which will result in a more sustainable mining.

Civil Construction is responsible for consuming large amounts of the non-renewable natural resources and generating significant environmental impacts, which begin with the extraction of the raw material for construction materials manufacturing, and extend to the end of the life cycle of the buildings. In this context, the development of more sustainable building materials is necessary as a way to mitigate the environmental impacts caused and contribute to the sustainable development of the sector. This paper brings the development of concrete bricks for interlocking pavement, manufactured from the addition of PET (Polyethylene Terephthalate) waste replacing part of the natural aggregates. For this, dosage studies were carried out in order to determine the dosage for bricks manufacturing. The bricks were produced and tested in order to verify their compression strenght and water absorption. At the end, the production costs of these bricks were estimated based on the SINAP 2015 table. The results showed that the developed bricks met the technical standard requirements for their use. However, in terms of costs, these have proved to be slightly more expensive than conventional parts. [ABSTRACT FROM AUTHOR]

The precast concrete is a building system that allows a rapid implementation and the quality control of the constructions and facilitates the rationalization of the building processes. The defect level and the quality of the construction finish is determined by a visual inspection and by comparison with photographic standards. The aim of this paper is to propose a methodology to classify the surface quality of the pieces of prefabricated concrete by image analysis, thereby reducing the subjective character and improving the process in the production plant. Framed with prefabricated concrete were produced in central and images were collected in pre-defined points and analyzed individually with an image analysis software, "image tool software". The images were treated by a digital manipulation of binarization using the tools provided by the software. After the treatment it was possible to determine the amount of bubbles, surface defects and its dimensional variation. It was then carried out a comparison with the images provided by the Guide for surface finish of formed concrete and a table with the size distribution and density of defects was compiled. The classification process of the surface quality of the pieces of precast concrete was obtained with a systematic way using the image análisis in this work. [ABSTRACT FROM AUTHOR]

In this paper we discussed about the brazilian High School Reform implemented by Provisional Measure n. 746, of 2016, and then consolidated in the Law no. 13.415 / 17. By using documentary and bibliographical research, we problematize its supposed purposes of improving the quality of education through curricular flexibilization and the expansion of schools with a full-time working day. We defend that the real purpose of this reform is to relativize some important concepts of national education, such as basic education, public, state and gratuitous education and teacher professionalization. We conclude that the ongoing Reform, on the one hand, responds to the interests of its main interlocutors, such as "All for Education" movement, by making flexible the need to hire licensed teachers, direct the curriculum to the formation of "productive personalities" and To expand the market for educational services. On the other hand, the Reform limits the future of young people. [ABSTRACT FROM AUTHOR]

This paper aims to reflect on some concepts of Nietzsche's philosophy by using Bart Simpson and Bartbely characters as cognitive triggers. The main idea is to manipulate cartoon and literature as ways of everyday expression, which can enhance children's interest in a philosophical debate that is immanent to the cultural products that surround them. The Nietzschean concepts of Moral, Nihilism and Superman will be discussed more carefully, as well as the possibility of a notion of the concept of Limit-of-Man. Such discussions are made on the basis of Deleuze's, Guattari's and Nietzsche's writings. [ABSTRACT FROM AUTHOR]

This paper presents a post-occupancy evaluation (APO) analysis of housing conditions in three (3) housing estates built by the Minha Casa Minha Vida Program - PMCMV in Blumenau SC, designed for homeless families from their homes because of environmental disasters (floods, waterlogging and floods) that have occurred in 2008 in the city. Through design reviews, site visits, technical surveys, questionnaires, interviews, analyzes were carried out encompassing evaluation of environmental comfort, functionality, urban ambience and sustainability. From this first analysis we selected three inhabitation areas for more detailed analysis of evaluation as mentioned before, if the nominees as the Hamburgo, Morada das Figueiras and Parque da Lagoa, located in the western region of the county. Overall the results show that there are the three (3) housing estates evaluated a standardized typology of apartments, not considering the diversity of family units; lack of architectural strategies regarding environmental comfort in the apartments and inefficient urban integration, highlighting the low public transport supply, leisure facilities, trade and support services. Also identified was still a feeling of abandonment by the residents and ease of drug trafficking in entry spaces condominiums generating insecurity. [ABSTRACT FROM AUTHOR]

In this work, the oil displacement process due to water injection in a two-dimensional geometry formed by parallel plates with a micro square cavity that, in simplified form, represents the pores of the oil reservoir rock is analyzed numerically. This was achieved with the Ansys Fluent software that uses the finite volume method. The main aim of this paper is the investigation of the influence of a rounded corner of the geometry in the oil displacement process. In the multiphasic, transient, Newtonian flow, capillary forces prevailing over the inertial and viscous forces. The results obtained, for the case with square corners, coincide with the work of Coelho, Pena e Romero (2016). The analysis shows that, for the four cases considered, at the end of the oil displacement process a portion of the oil will remain trapped in the microcavity. Additionally, for the considered geometry, independent of the radius of curvature of the rounded corners, there are three distinct regions when evaluating the average oil volume fraction. A first region, where the reduction of oil is accentuated, then a second region, where the oil displacement becomes slower, and finally a third region, identified by the saturation of the residual oil. The process becomes more efficient as the radius of curvature of the micropore with rounded corners increases. This relation, at least for the cases analyzed, is linear. [ABSTRACT FROM AUTHOR]

In this paper, the CONASAT (Environmental Nanosatellite Constellation) project will be presented. This initiative has been developed by the INPE (National Institute For Space Research) in partnership with the AEB (Brazilian Space Agency) and UFRN (Federal University of Rio Grande do Norte). The principal objective of this project is to design a low cost solution for the Brazilian Environmental Data Collecting System (SBCDA) based on a nanosatellite (weighing between 1kg and 10kg) constellation and using emerging technologies from the electronic and telecommunication fields. Moreover, a general view of the main CONASAT products will be presented: the Receiver/Decoder system, which is compatible with the SBCDA and the ARGOS system, called Environmental Data Collector (EDC); and the software developed for the nanosatellite Attitude Determination and Control System (ADCS). The former is used to receive and decode the data from the PCDs (Data Collecting Platforms) and the second is used to change the satellite orientation with respect to a specified reference frame according to the operational necessities. Finally, some conclusions and comments about the CONASAT project will be presented. [ABSTRACT FROM AUTHOR]

This paper report an investigation aimed at analyzing how internationalization experiences developed under the Programa Ciência Sem Fronteira (CsF) imply the human development of undergraduate students from the Francisco Beltrão Campus, from the Universidade Tecnológica Federal do Paraná (UTFPR ), located in the southwest region of Paraná. Thirteen (81.25%) participated in the study, 7 male and 6 female, out of a total of 16 who participated in the CsF on the Campus. The group was graduated in Environmental Engineering, Food Engineering, Chemical Engineering, Degree in Computer Science and Food Technology. Semistructured interviews were carried out and through content analysis principles it was possible to identify the categories Culture and Autonomy. Language, World Vision, Prejudice, Eating Habits, Routine of Studies, were the elements that emerged in the interviews that support what we call the Culture category. The elements Independence, Maturity, Responsibility, Self-knowledge, Courage and Discipline, which, in turn, support what we call the Autonomy category in this study. From the analysis process, it can be inferred that the international experience, provided by the Science Without Borders Program, brought to each of the students a process of change, that is, it gave them implications in their human development.

The technology can be considered important ally in solving problems in different productive sectors of Brazil. For Agribusiness, may involve improving productivity without increasing the exploitation of productive areas and assist in ensuring the health issues. So there is this process of creation and innovation is needed that knowledge is stimulated. The paper aims to verify the presence of knowledge in spaces intended for Agribusiness, check especially (i) government incentives for technology development, (ii) the production of agricultural machinery and (iii) the geographical indications in the country. For both data collections were made at various government sites and in the yearbook of the National Association of Automobile Manufacturers. The results indicate that there are programs and financial incentives for technology development, and most activities are consistent with the global technological trends. It is emphasized that the activities of the production and marketing of agricultural machinery stand out in 2014 in the southern region of the country. With respect to geographical indications, the year 2012 has the largest number of accepted indications, sticking to wine production. Implicitly or explicitly, knowledge is present and influences the continuity and advances in technological elements that can positively change the context. [ABSTRACT FROM AUTHOR]

This paper presents theoretical discussions about the teacher's authority in the classroom. The question to be addressed is about the best teacher's attitude in front of inadequate action student in classroom. A real case in the classroom is reported and discussed positions of some authors who deal with the subject looking to deepen the definition of the teacher's role in the classroom. We conclude that the teacher's authority is established from the way they relate to their students, their skills in the area of knowledge and ability to face situations that require creativity and reflective attitude.
