14. FLEXIBLE RISERS MONITORING TECHNIQUE BASED ON VIBRATION MEASUREMENTS / MONITORAMENTO DE RISERS FLEXÍVEIS ATRAVÉS DE TÉCNICA BASEADA EM VIBRAÇÕES
The main failure in flexible risers is the disruption of the wires from the tensile armor layer. Experience has shown that this class of damage occurs primarily near to the top riser connector. The breaking of the wires occurs gradually and may be caused by different processes as corrosion by inflow of fluid in the annular space, excessive wear associated wi

15. AVALIAÇÃO AMBIENTAL POR GEOPROCESSAMENTO NA SUB-BACIA DO RIO ANGASMARCA, REGIÃO LA LIBERTAD, PERU. / ENVIRONMENTAL ASSESSMENT BY GEOPROCESSING OF THE SUB-BASIN ANGASMARCA RIVER, IN LA LIBERTAD REGION, PERU.
As atividades agropecuárias, sem considerar as potencialidades e limitações quanto ao uso das terras, são uma fonte potencial de degradação do meio ambiente. O trabalho teve por objetivo fazer um diagnóstico ambiental na sub-bacia do rio Angasmarca, na Região La Libertad no Peru, utilizando técnicas de geoprocessamento. Para a execução do trabalho

16. Transformações do espaço e estratégias mercantis na Lagoa Jacuném / Transformações do espaço e estratégias mercantis na Lagoa Jacuném
Nature, present in abundance in the past, with the passage of time has been transformed into rare element. With the growth of cities, it has been transformed, replaced by the built environment and destroyed, getting loads of pollutants and surviving in small fragments. The impossibility of its recreation as it was in the past, turned nature into a rare and a

18. El descenso de las actitudes hacia la ciencia de chicos y chicas en la educación obligatoria
An empirical analysis of the deterioration of the science related attitudes across students' age and sex is presented. The attitudinal factors embrace a group of variables on the image of science, environmental preservation and some aspects of school science and have been analyzed in a sample of students across several ages starting at the fourth grade. The

19. Condições de armazenamento e conservação do potencial fisiológico de sementes de diferentes genótipos de milho / Storage conditions and seed performance of different corn genotypes
Seed storability is affected by several factors including genotype and environmental conditions. Corn seed producers are highly concerned with variations in seed longevity of different hybrids, resulting in lower performance than desired during the normal sowing season as much as during off season times. The objective of this research was to evaluate the eff

20. Cellular aging: theories and technological influence
The aim of this article was to review the factors that influence the aging, relationship of aging with the biological rhythms and new technologies as well as the main theories to explain the aging, and to analysis the causes of aging. The theories to explain the aging could be put into two groups: those based on a program that controlled the regression of th

21. Evaluation of the effect of dry-film biocides on paint film preservation using neural networks
Biocides play an important role in the preservation of a variety of products susceptible to microbiological growth such as paint, a material that can undergo microbial deterioration both in storing (inside the can) and after the application on a surface. In this work, artificial neural networks were used to predict the level of fungal growth on surfaces pain

22. Contribution to the development of performance specifications for concretes containing blast furnace slag / Contribuição ao desenvolvimento de especificações por desempenho para concretos com escoria de alto-forno
In 2008 alone, the annual steel production in Brazil was around 31 million tons. The steel production process generates an average of 500 kg of residues and co-products per ton of steel. From this total, 70% corresponds to the slags. Although investigating the increase of blast furnace slag use is of extreme importance for the concrete and steel industries s

23. Emprego da técnica de emissão por fluorescência de ultravioleta no monitoramento de inibidores de corrosão em água produzida / Use of ultraviolet fluorescence emission in the monitoring of corrosion inhibitor in produced water
In order to increase the volume of oil extraction, solve and prevent problems in oil production, several chemical products are used. Corrosion inhibitors are the main chemical products used in the whole oil production chain, whose objective is to protect the system from deterioration caused by corrosion. The quaternary ammonium salts are the kind of inhibito

24. La conformación de la antropoética a través de la tutoría académica en educación superior: (el caso del posgrado)
Nowadays to talk about violence, war, terrorism, climate change, environmental damage and social deterioration, is to speak of a humanitarian crisis. With globalization comes human loss due to the hegemony of the market, technology and information, all of which can happen gradually or suddenly. We are living in a period in which we must reconcile matter and
