25. The invasive white ginger lily ( Hedichium coronarium ) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir
ABSTRACT The invasive white ginger lily (Hedichium coronarium - J. Köenig, 1783) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir. Invasive plants are believed to shift the trait composition of aquatic insects dwelling in banks of lentic ecosystems. In this study, we analyzed the relationship between the p

26. INFLUENCE OF THE MODEL SCALE ON HYDRODYNAMIC SCALING IN CFB BOILERS
Abstract The paper presents the results of experimental verification of the simplified set of scaling parameters for which the particle density as well as the cold model length scale may be chosen independently. The tests were carried out on two large scale 1/10 and 1/20 geometrically similar cold models of the Lagisza 966 MWth supercritical CFB boiler. The

27. Simplification of Lipase Design in the Enzymatic Kinetic Resolution of Amines by Saturation Transfer Difference NMR
In this work, we demonstrate a nuclear magnetic resonance (NMR) method for racemic amide and lipase interaction as a first-pass design method in the enzymatic kinetic resolution of amines. As a novel adaptation of commonly used protein-ligand screening NMR methodologies, this approach relies upon a lipase-amide interaction wherein the time-consuming is reduc

28. Análisis numérico del ámbito de validez del modelo convencional de tiro oblicuo
In a diagnosis survey about ballistics, given to a group of undergraduate students, a high percentage of wrong answers was obtained about estimates of air resistance and other phenomena affecting the movement of a projectile. These mistakes are related to a simplified model widely used in textbooks as well as in lectures. This model assumes that the variatio

29. Investigation on the optimal simplified model of BIW structure using FEM
Abstract At conceptual phases of designing a vehicle, engineers need simplified models to examine the structural and functional characteristics and apply custom modifications for achieving the best vehicle design. Using detailed finite-element (FE) model of the vehicle at early steps can be very conducive; however, the drawbacks of being excessively time-con

30. Externalización de la gestión documental audiovisual en las televisiones por medio de productoras audiovisuales y agencias de noticias
Simplification is analyzed in regards to content analysis methods of television archives, derived from various factors such as the restructuring of the documentary-making organization changes to human and economic resources and the acquisition of content analysis description from creative companies such as producers, audiovisual and news agencies. Both facto

31. Board of directors and top management team : a study on CEO relative power and financial return
Best corporate governance practices published in the primers of Brazilian Securities and Exchange Commission and the Brazilian Corporate Governance Institute promote board independence as much as possible, as a way to increase the effectiveness of governance mechanism (Sanzovo, 2010). Therefore, this paper aims at understanding if what the managerial literat

32. Informatividade nos textos opinativos escritos em situação escolar
This research, which is about the informativity of textuality as a factor in the opinionated text redaction performed as an exercise in schools, from the restlessness caused by repetition of the same ideas in the expression of opinionated students, what we name here common sense. Also motivated by the evident importance given to the students written producti

33. A robustez de um sistema de distribuição e a alocação de medidores de qualidade da energia elétrica frente aos afundamentos de tensão / The robustness of a distribution system and an allocation of power quality monitors in the face of the voltage sags
This dissertation aims to initially reintroduce and spread the Fault Positions Method (FPM) as an analytic means to determine the remaining voltage in all bus bar constituents of a Distribution System (DS), upon the occurrence of voltage sags. By applying this method, it is possible to formulate the during fault voltage matrix, thus denoting the influence an

34. In-flight collision avoidance controller based only on OS4 embedded sensors
The major goal of this research was the development and implementation of a control system able to avoid collisions during the flight for a mini-quadrotor helicopter, based only on its embedded sensors without changing the environment. However, it is important to highlight that the design aspects must be seriously considered in order to overcome hardware lim

35. Creep-age forming of AA7475 aluminum panels for aircraft lower wing skin application
Creep-age forming (CAF) is an interesting process for the airframe industry, as it is able to form or shape panels into smooth, but complex, curvatures. In the CAF process, the ageing cycle of the alloy is used to relax external loads imposed to the part, through creep mechanisms. Those relaxed stresses impose a new curvature to the part. At the end of the p
