1. Morphometry and longitudinal profile of the river cobras sub-basin in planning the location of underground dams
RESUMO Um estudo na sub-bacia hidrográfica do rio das Cobras foi realizado com o objetivo de avaliar as características morfométricas e o perfil longitudinal da bacia hidrográfica, como ferramenta de planejamento na locação de barragens subterrâneas. Os parâmetros morfométricos - coeficiente de compacidade, fator forma, densidade de drenagem e índi

2. Obesity, Prejudice, Self, and Culture: A Longitudinal Case Study
Resumo Com o número crescente de obesos no Brasil aumenta também a importância de estudos dedicados à investigação do impacto social e psicológico da obesidade. Esse estudo objetivou identificar e analisar os processos de construção subjetiva da experiência de obesidade. Trata-se de um estudo de caso longitudinal com uma mulher obesa de 29 anos sub

3. A dinâmica da atenção governamental sobre as políticas de saúde no Brasil: equilíbrio e pontuações nas primeiras décadas pós-redemocratização (1986-2003)
Resumo Este trabalho tem o objetivo central de mapear e analisar a atenção de alguns atores e instituições sobre as políticas de saúde no Brasil entre 1986 e 2003. Esse modelo de pesquisa sobre agenda governamental é conhecido sob o termo “dinâmica de políticas” (policy dynamics) e analisa o processo de mudança de políticas públicas por meio

4. Fish metacommunity structure in Caño Maraca, an important nursery habitat in the Western Llanos of Venezuela
ABSTRACT We investigated spatial and seasonal variation of fish assemblages of Caño Maraca, a creek in Venezuela’s Western Llanos, a region with strong wet-dry seasonality. Fishes were surveyed over a 19-year period at three sites along the longitudinal gradient: a headwater site with a narrow channel, a middle site with shallow channels traversing a seas

5. Adaptive Fuzzy Sliding-Mode Control of Wheel Slide Protection Device for ER24PC Locomotive
Abstract Wheel Slide Protection Devices (WSPD) are employed in railway vehicles to maximize the average of the possible frictional braking force, which is a nonlinear function of the slip ratio of the wheel sets. In this paper, to control the WSPD, a low-order model is presented and un-modeled dynamics are considered as uncertainties. Due to the nonlinear dy

6. Postural balance in Alzheimer's disease patients undergoing sensory pitfalls
Abstract Despite consensus regarding the interference of cognitive processes on the human balance, the impact that different sensory stimuli have on the stabilometric measures remains unclear. Here, we investigated changes in the postural balance of individuals with Alzheimer's disease (AD) and in healthy controls undergoing different proprioceptive and some

7. Estudio del impacto y efectos de la crisis económica en las políticas de protección social del ámbito local en España. Análisis de caso de la región de murcia (España)
The paper presents the results of an empirical research aimed at discovering and analyzing the effects of the economic crisis on the needs and benefits of social protection system offered locally. For their achievement has made a longitudinal investigation of needs and capabilities in a municipality in the eastern region of Murcia during the period between 1

8. An Extended Kalman Filter-Based Technique for On-Line Identification of Unmanned Aerial System Parameters
ABSTRACT: The present article deals with the identification, at the same time, of aircraft stability and control parameters taking into account dynamic damping derivatives. Such derivatives, due to the rate of change of the angle of attack, are usually neglected. So the damping characteristics of aircraft dynamics are attributed only on pitch rate derivative

9. Recubrimiento controlado de sustratosde vidrio con nanobastones metálicos
ABSTRACTMonodispersed gold nanorods were synthesized with efficiency above 80% of all nanoparticles, characterized by longitudinal plasmon resonance around 800 nm. Glass substrates were surface modified and covered with the synthesized nanorods with control of surface density. Coverage dynamics was monitored through extinction spectra, and a saturation maxim

10. An optimal integrated longitudinal and lateral dynamic controller development for vehicle path tracking
AbstractIn this paper, an optimal controller for integrated longitudinal and lateral closed loop vehicle/driver dynamics proposed to follow desired path in various driving maneuvers, which also improved maneuverability and stability of vehicle over desired path. Designed controller imposed corrected steering angle and torque on the wheels to keep the vehicle

11. Where do these bugs come from? Phenotypic structure of Triatoma infestans populations after control interventions in the Argentine Chaco
House re-invasion by native triatomines after insecticide-based control campaigns represents a major threat for Chagas disease vector control. We conducted a longitudinal intervention study in a rural section (Area III, 407 houses) of Pampa del Indio, northeastern Argentina, and used wing geometric morphometry to compare pre-spray and post-spray (re-infestan

12. Stick-slip analysis in vibrating two-layer beams with frictional interface
This paper attempts to present a new analysis for dynamical behavior of two-layer beams with frictional interface which held together in a pressurized environment, including stick-slip nonlinear phenomenon. To achieve a proper outlook of two-layer beam structures behavior, it is essential to realize the mechanisms of motion precisely. Coupled equation of tra
