25. Management of painful temporomandibular joint clicking with different intraoral devices and counseling: a controlled study
Objective The benefit of the use of some intraoral devices in arthrogenous temporomandibular disorders (TMD) patients is still unknown. This study assessed the effectiveness of the partial use of intraoral devices and counseling in the management of patients with disc displacement with reduction (DDWR) and arthralgia. Materials and Methods A total of 60

26. A time-domain finite element model reduction method for viscoelastic linear and nonlinear systems
AbstractMany authors have shown that the effective design of viscoelastic systems can be conveniently carried out by using modern mathematical models to represent the frequency- and temperature-dependent behavior of viscoelastic materials. However, in the quest for design procedures of real-word engineering structures, the large number of exact evaluations o

27. Low-velocity Impact Response of a Nanocomposite Beam Using an Analytical Model
AbstractLow-velocity impact of a nanocomposite beam made of glass/epoxy reinforced with multi-wall carbon nanotubes and clay nanoparticles is investigated in this study. Exerting modified rule of mixture (MROM), the mechanical properties of nanocomposite including matrix, nanoparticles or multi-wall carbon nanotubes (MWCNT), and fiber are attained. In order

28. Arthroscopic treatment of adhesive capsulitis of the shoulder with minimum follow up of six years
OBJECTIVE: To evaluate the results of the arthroscopic treatment of adhesive capsulitis of the shoulder with six to nine years of follow up.METHODS: From August 2002 to December 2004, ten patients underwent arthroscopic capsular release for adhesive capsulitis refractory to conservative treatment. An interscalene catheter was used for postoperative analgesia

29. Subjective time perception is affected by different durations of exposure to abstract paintings that represent human movement
Time perception can be affected by real emotional pictures of people that evoke different levels of arousal. Figurative artwork images of body postures that imply movement with different intensities and evoke different levels of arousal can modulate the perception of time. The present study investigated whether abstract paintings that represent motion in dif

30. Seismic response of aboveground steel storage tanks: comparative study of analyses by six and three correlated earthquake components
Ground motions at a point on the ground surface can be decomposed to six components, namely three translational components and three rotational components; translational components include two components in the horizontal plane, and one in the vertical direction. Rotation about horizontal axes leads to rising of rocking, while the rotational component about

31. Investigation of the heave dynamics of Air Cushion Vehicles (ACV): parametric and chaotic studies
A highly non-linear model for the dynamics behavior of Air Cushion Vehicles (ACV) is presented. In this model the compressible Bernoulli's equation, the Newton's second law of motion, and the nonlinear isentropic relations are used to predict the dynamics behavior of only the vertical response of the ACV in both time and frequency domains. In this paper the

32. Cutting force response in milling of Inconel: analysis by wavelet and Hilbert-Huang Transforms
We study the milling process of Inconel. By continuously increasing the cutting depth we follow the system response and appearance of oscillations of larger amplitude. The cutting force amplitude and frequency analysis has been done by means of wavelets and Hilbert-Huang transform. We report that in our system the force oscillations are closely related to th

33. Cinemática da marcha de crianças com desenvolvimento típico e com paralisia cerebral diplégica espástica nível I e II do GMFCS: um estudo comparativo
The objective of the study is compare, using PCA, the kinematics of the pelvis, hip, knee and ankle during gait between typical and spastic diplegic cerebral palsy GMFCS I and II children. Cross-sectional observational study was realized with 56 children, aged 6 to 12 years (9.0±SD), divided into three groups: children level I of the GMFCS; children level I

34. Attitude Control of a Satellite by Using Digital Signal Processing
Abstract: This article has discussed the development of a three-axis attitude digital controller for an artificial satellite using a digital signal processor. The main motivation of this study is the attitude control system of the satellite Multi-Mission Platform, developed by the Brazilian National Institute for Space Research for application in different s

35. Influence of physical and geometrical system parameters uncertainties on the nonlinear oscillations of cylindrical shells
This work investigates the influence of physical and geometrical system parameters uncertainties and excitation noise on the nonlinear vibrations and stability of simply-supported cylindrical shells. These parameters are composed of both deterministic and random terms. Donnell's non-linear shallow shell theory is used to study the non-linear vibrations of th

36. Análise da cinemática de corredores adultos jovens e idosos
The kinematics of elderly runners might represent the strategies used to produce sports motion due to their physiological and biomechanical characteristics. The investigation of pelvis and lower limb motion in elderly runners could help to understand the differences observed between elderly and adults during running. The aim of this study was to investigate
