Analises da nanociência e nanotecnologia na perspectiva de ciência, tecnologia e sociedade cts

In this contribution, we discuss and analyze some aspects of nanoscience and nanotechnology, based on the approach kwon as Science, Technology and Society (STS), as well as the prospects of Philosophy of Technology. In this context, we specify the constitute the nanoscience and nanotechnology analytic research field. I is also reported its genesis and limits, emphasizing the impacts of nanotechnology in the development of the contemporary society, such as the possible benefits and problems associated to the use of nanotechnology, as well as environmental impacts, doubts and uncertainties that permeate this areas, in addition some ethical questions and public policies for the sector are analyzed.

Investigação geoambiental de áreas contaminadas com elaboração do modelo conceitual em campo utilizando ferramentas de alta resolução (HRSC)

The Brazilian geo-environmental site characterizations usually do not provide a suitable Conceptual Site Model (CSM). Site assessments are mostly inappropriate and there is a lack of knowledge about the subsurface environment, generated by inconsistent data that will guide risk analyses and remediation projects full of uncertainties, causing delay on closing cases, inefficient remediation and higher global projects costs. The step of data collection must have high priority to develop a suitable CSM,, and it demands more effective high resolution site characterization (HRSC) tools than the traditional ones and, preferably, the decision-making have to be done in the field. This paper presents and discusses two geo-environmental site characterization results, in which the decision-making was done in the field based on high resolution site characterization (HRSC) used together with the traditional ones. These site investigations provided a significant time saving, allowed the detection of subsoil heterogeneities, a proper understanding of the subsurface environmental, and have generated a solid CSM in real-time. These CSM can subsidize remediation projects based on a more reliable data than those that would be obtained in traditional site investigations, concerned just in following the rules established by the environmental agencies.

Inclusão escolar na percepção de professores do município de Dois Córregos, São Paulo

This paper aims to make a survey about the inclusion of children in need of special care in all schools and day nurseries (publics and privates) in ?Dois Córregos? city, in São Paulo. We interviewed 144 teachers and 14 school principals in 14 educational establishments ? 5 private schools, 5 state-owned schools, 2 municipal schools, 1 municipal nursery and 1 philanthropic nursery. The research aimed to investigate possible prejudices against the children in need of special care; verify if the schools have adequate infrastructure to receive the students in need of special care; and verify if the professionals who work in the schools are receiving (or received) specific training to work on this inclusion process. The results indicated that teachers who don?t work with children in need of special care are very insecure in receiving them. It?s evident that there are a lot of doubts and uncertainties about the inclusion system. In general, schools don?t have adequate infrastructure and most of the time the included students are those who have internal deficits, which are not evident.

Aplicação da teoria da confiabilidade em estacas escavadas de grande diâmetro para obtenção das superfícies resistentes de projeto

In this work, the author looks forward to develop a new method capable of incorporate the concepts of the Reliability Theory and Ruin Probability in Deep Foundations, in order to do a better quantification of the uncertainties, which is intrinsic in all geotechnical projects, meanly because we don't know all the properties of the materials that we work with. Using the methodologies of Decourt Quaresma and David Cabral, resistance surfaces have been developed utilizing the data achieved from the Standard Penetration Tests performed in the field of study, in conjecture with the loads defined in the executive project of the piles. The construction of resistance surfaces shows to be a very useful tool for decision making, no matter in which phase it is current on, projecting or execution. The surfaces were developed by Kriging (using the software Surfer® 12), making it easier to visualize the geotechnical profile of the field of study. Comparing the results, the conclusion was that a high safety factor doesn't mean higher security. It is fundamental to consider the loads and resistance of the piles in the whole field, carefully choosing the project methodology responsible to define the diameter and length of the piles
