1. Extreme non-viable candidates and quota maneuvering in Brazilian legislative elections
Resumo Este artigo explora as causas e consequências de candidaturas extremamente não viáveis, também chamadas de “candidaturas laranjas”, no folclore político do Brasil. Nós procuramos definir, primeiramente, o que torna uma candidatura a ser identificada como laranja, empregando a literatura comparada sobre sacrificial lambs, mas também envolven

3. Multi-objective Optimization Method For Repeat Ground-track Orbit Design Considering the Orbit Injection Error
ABSTRACT: Considering the adverse effects of orbit injection error, a novel repeat ground-track orbit redesign approach is proposed to reduce the fuel consumption caused by the orbital maneuvering from the injection orbit to the nominal orbit. By introducing the performance indexes of revisiting accuracy and orbit injection maneuvering fuel consumption, the

4. Controlled synthesis of noble metal nanomaterials: motivation, principles, and opportunities in nanocatalysis
ABSTRACT This review describes some principles of the controlled synthesis of metal nanoparticles, focusing on how the fundamental understanding of their synthesis in the solution-phase can be put to tailor size, shape, composition, and architecture. The maneuvering over these parameters not only enable the tuning of properties, but also the maximization and

6. Concept of a Maneuvering Load Control System and Effect on the Fatigue Life Extension
Abstract This paper presents a methodology for the conceptual design of a Maneuver Load Control system taking into account the airframe flexibility. The system, when switched on, is able to minimize the bending moment augmentation at a wing station near the wing root during an unsteady longitudinal maneuver. The reduction of the incremental wing bending mome

7. Dynamic Analysis of Maneuvering Flexible Spacecraft Appendage Using Higher Order Sandwich Panel Theory
Abstract This paper is devoted to the vibration of rotating flexible spacecraft. The maneuver of the spacecraft is modeled by a constant torque input acting on the hub. For the first time in this paper the equations of motion of flexible spacecraft are derived based on higher order sandwich panel theory (HSAPT). Hamilton's principle is used for driving the g

8. A Novel method of ensuring safe and accurate dilatation during percutaneous nephrolithotomy
ABSTRACT Objective: To report our technique that helps locate the guidewire into the ureter enabling safe dilatation during PCNL. Materials and Methods: Cases in which the guidewire failed to pass into the ureter following successful puncture of the desired calyx were subjected to this technique. A second guidewire was passed through the outer sheath of a

12. Análise do acoplamento entre o controle de atitude e de trajetória durante manobras orbitais de empuxo contínuo / Coupling analysis between attitude control and orbital maneuvering trajectory during continuous thrust
This work considers the coupling between attitude and orbit control used during an orbital transference which uses a continuous propulsive system capable impulse for a long time. The dynamic equations of movement are used to propagate the orbit and attitude states. It is studied some cases which comes from the effect of control during the orbital transferenc
