13. Contribuição ao estudo da concepção de projetos de capital em mega empreendimentos
The process of design of capital projects has been the object of much attention from large companies. Special emphasis has been given to the management methods of the design of these projects, and even more with regard to initial stages of design. In this context, this paper presents a conceptual framework to preplanning stage of capital projects, with empha

14. Método bivalorado para medições subjetivas / Two-value method for subjective measurements
Background: Due to the growing need to better understand the organizational elements, subjective measurements are gaining more and more space. Problem: can we assess how reliable a data sample collected via 2-value subjective measurement is in relation to the reality of the attribute of a measurand? Hypotheses: Hypothesis 1 - there is already a scientific me

15. MODELO DE ESTIMATIVA DA RADIAÇÃO LÍQUIDA E SUA APLICAÇÃO NA DETERMINAÇÃO DA EVAPOTRANSPIRAÇÃO POTENCIAL
This study aimed to assess and develop a physical mathematical model to estimats the net radiation. For this we used weather data collected from the meteorological station of the Department of Physics and Meteorology of the Escola Superior de Agricultura "Luis de Queiroz" - ESALQ - University of São Paulo - USP, Piracicaba, Brazil, according to the global r

16. RegeneraÃÃo "in vitro", estudos histolÃgicos e transformaÃÃo genÃtica da momoneira (Ricinus communis) / "In vitro" regeneration, histologycal studies and genetic transformation of castor-bean (Ricinus communis)
Castor bean (Ricinus communis) is an oilseed crop with considerable economic value because of the composition of its oil seed. However, there are some constraints in your use for human and animal food because of the presence of toxic and allergenic proteins. This problem could be solved or reduced through genetic engineering. However, this crop is recalcitra

17. Modificação do LLDPE através de silanos viabilizando a aplicação em camadas plásticas de linhas flexíveis / Study of silane grafting reactions of low density polyethylene for pipe applications
The flexible lines are flexible structures manufactured through plastic and steel layers that allows its use in order to permit fluid flow in exploration and production of hydrocarbon between offshore oil units and sea bed and/or coast. Nowadays these pipes are one of the main ways to permit the exploration of hydrocarbon in deepwater. The present study aims

18. Desenvolvimento de um sistema de aquisiÃÃo e armazenamento de dados microcontrolado
The data acquisition systems are present in many studies, cooperating on collection, storage and analyses of data. On farming field, these systems are used in experiments of agricultural machines, soil characteristics study, as well as in other applications where data collection by sensors is needed. In the present study, a data acquisition system was develo

19. Modelo matemático do processo de purificação do ácido clavulânico por troca iônica em coluna de leito fixo
Clavulanic acid (CA) is a β-lactam antibiotic produced industrially by submerged cultures of the filamentous bacterium Streptomyces clavuligerus. Due to its importance, several studies on the purification of clavulanic acid have been conducted at the Department of Chemical Engineering of the Federal University of São Carlos DEQ-UFSCar. As a natural seq

20. Technology transfer from academy to industry: a functional approach. / Transferência de tecnologia do meio acadêmico para o setor produtivo: uma abordagem funcional.
This work started from a perception that the level and effectiveness of technology transfer from universities to industry can be increased in Brazil. First, the importance of this process is highlighted, bringing up the potential benefits to all parties involved, directly and indirectly, and also the barriers posed to this kind of partnership. The possibilit

21. MÉTODOS APROXIMADOS DE SOLUÇÃO DE SISTEMAS DINÂMICOS NÃO-LINEARES / APPROXIMATE SOLUTION METHODS FOR NONLINEAR DYNAMICAL SYSTEMS
Nonlinear dynamical systems are rather common in engineering. This class of problems is usually solved by numerical integration or through the use of ap- proximate analytical methods (perturbation methods) or semi-analytical meth- ods such as the harmonic balance method. The numerical integration is a slow and cumbersome process in parametric analyses. The o

22. Methodology of production strategy optimization based on genetic algorithms / Metodologia de otimização probabilistica de estrategias de produção baseada em algoritmos geneticos
High levels of uncertainty and associated risks in the exploration and production of some oil fields suggest the use of probabilistic optimized production strategies. Therefore, an appropriate production strategy should be chosen considering various geological and economic scenarios. In this work, a new approach for the optimization is proposed where the pro

23. IrrigaÃÃo e fertirrigaÃÃo em um sistema de aspersÃo convencional submetido à tÃcnicas de controle estatÃstico de qualidade. / Irrigation and fertigation in sprinkler system submitted to techniques of statistical quality control
The contribution of irrigation in the alimentary supply, is due to the fact of more and more to look for more efficient systems, monitoring the indexes of uniformity of distribution of the water. The application of fertilizers through irrigation water took very big pulse in the last times, mainly due to the emergence of pressurized systems, of the tunnels of
