13. Análise de desempenho e ruído de hélices de mínima perda de energia / Analysis of performance and noise of propellers minimum energy loss
Revisa os métodos para cálculo de desempenho e ruído de hélices. Apresenta um método para determinação de desempenho de hélices com mínima perda de energia usando a teoria dos vórtices. Faz uso das tabelas de Goldstein que criam automaticamente a geometria da hélice através do acesso a um banco de dados aerodinâmico. Avalia o ruído harmônico c

16. Effect of mixing mode on the behavior of an ASBBR with immobilized biomass in the treatment of cheese whey
A hydrodynamic study of a mechanically stirred anaerobic sequencing batch biofilm reactor (ASBBR) containing immobilized biomass on polyurethane foam was performed with the aim to determine homogeneity of the reactor based on total mixing time. Turbine or helix propellers were used for stirring at rotor speeds of 100, 200, 300 and 500 rpm. Experimental value

17. Kinetics of barium sulphate reaction crystallization in crystallizers with internal circulation
Kinetic calculation results describing the observed nucleation and growth rates of barium sulphate crystals precipitated in an integrated reaction-crystallization process in a barium sulphate-ammonium chloride-water system are presented and analyzed. The scope of experiments included two continuous model DTM-type crystallizers (Draft Tube Magma) with interna

18. A fatura na obra de Fábio Miguez
The present research has as its study object the production process in the pictorial development. Through a phenomenological approach, we find instruments that assist us in thinking the process of production of painting. As a case study for our research we chose the work of the São Paulos artist Fábio Miguez in the period between 1983 and 2000. We consider

19. Contribuições de famílias para o rendimento escolar de alunos de 1 a 4 séries do ensino fundamental: olhares das responsáveis e das professoras
In contemporaneity, educational paradigms point out the importance of the involvement and the contribution of the family to childrens school life. Besides the family, the school and the pupil contribute to a better or worse school performance. It is in this context that the present study is inserted and had as its general objective to investigate how familie

20. Análise por modelagem e dinâmica molecular da interação entre a integrina α6β1 e a laminina 111 humana / Molecular modelling and dynamics analisys of human α6β1 integrin and laminin 111 interaction
The extracelullar matrix (ECM) is formed by an assembly of proteins and glycoproteins which surrounds the cells, in various tissues. The laminin is a glycoprotein localized in the ECM that consists of three polypeptidic chains cross- shaped. It functions by anchoring epithelial cells to basal lamin, through associations with integrins, collagen, elastin and

21. Simulação da interação casco-propulsor de uma embarcação usando mecânica dos fluidos computacional (CFD). / Simulation of the propeller-hull interaction using computational fluid mechanics (CFD).
Este trabalho discute a questão da interação entre o casco do navio e o propulsor em funcionamento conjunto, e sua simulação por ferramentas computacionais. O texto se concentra em descrever os principais efeitos dessa interação, as principais dificuldades em se estimar esses efeitos, os métodos tradicionalmente usados, e como ferramentas computacion

24. Adaptive techniques applied to offshore dynamic positioning systems
Dynamic positioning systems (DPS) comprise the deployment of active propulsion to maintain the position and heading of a vessel. Several sensors are used to measure the actual position of the floating body, while a control algorithm is responsible for the calculation of forces to be delivered by each propeller, in order to counteract all environmental forces
