1. Oscilación de un disco giratorio visto desde un sistema de referencia en rotación
The ratio relation 1:2 between rotation and wobbling frequencies of a torque free spinning plate or disc as seen from an inertial frame is calculated using a toy model for the disc. From a convenient rotating frame, the body oscillates as a pendulum in a centrifugal field, which simplifies the description of its movement. Thus, the ratio relation is simpler

2. Anteroposterior dentoalveolar effects with cervical headgear and pendulum appliance: a systematic review
AIM: The aim of this systematic review was to compare the maxillary dental effects of cervical headgear and pendulum appliance during distalization of permanent maxillary first molars. METHODS: A literature survey from databases covering the period from 1956 to August 2008 was carried out. Randomized controlled trials (RCT) and controlled clinical trials (CC

3. The Political Participation, Student Movement in Brazil: Dissent and Submission (1960 to 2009) / atuação da união nacional dos estudantes UNE: do inconformismo à submissão ao Estado (1960 a 2009)
This work follows the research method of The State and Educational Policies of the after-graduation program in Education of Federal University of Goiás. It addresses the importance of the participation of the university students in Brazil, from 1960 to 2009. The base is the hypothesis is that The Advent of the Social State, characterized by the constitution

4. Motor Control Modeling to Entropy Generation Minimization in Peripheral Mechanical Processes / Modelagem do controle motor para minimização de geração de entropia em processos mecânicos periféricos
Objectives: Classical studies showed that the transition among gait patterns, in vertebrate locomotion, occur when there is an increase in energetic demand. Since the muscular movement is performed under central nervous system control, it is this one that determines the gait pattern in the end. Therefore, this structure is able to translate mechanical events

5. Computer modelling and simulation of human posture in standing with neuromuscular reflexes / Modelagem e simulaÃÃo do controle da postura ereta humana quasi-estÃtica com reflexos neuromusculares
This work presents a computer mathematical model of the human neuromusculoskeletal system specially designed to study the postural balance in standing. In addition to the extrafusal muscle tissue properties commonly used in traditional muscle models applied to study human movement and posture, this model includes two components physiologically important of p

6. O fenÃmeno dos movimentos pendulares dos trabalhadores intermunicipais entre cidades de porte mÃdio: o caso de Cascavel e Toledo (PR). / The phenomenon of the pendulum movements of the commuters between towns of medium size: the case of Cascavel and Toledo (PR).
O objetivo central desse trabalho foi examinar o fenÃmeno dos movimentos pendulares dos trabalhadores intermunicipais entre as cidades interioranas de porte mÃdio de Cascavel e de Toledo, localizadas na MesorregiÃo Oeste do Estado do ParanÃ. A importÃncia de se estudar o fenÃmeno dos movimentos pendulares, especificamente dos trabalhadores, se faz devi

7. Cephalometric evaluation after the Pendulum appliance distalization in patients under fixed orthodontic treatment. / Avaliação cefalométrica pós-distalização realizada por meio do aparelho Pendulum, em pacientes em tratamento ortodôntico com aparelho fixo
The Pendulum appliance has been shown to be very effective in maxillary molar distalization for the Class II molar relationship correction. However, many side-effects were observed: upper premolars mesial tipping and mesial movement; lower anterior face height increase and considerable distal tipping of the first molars, turning molar distalization to be ins

8. ESTUDO DE SISTEMAS ATIVOS PENDULARES PARA O TRANSPORTE EM VEÍCULOS COM CARGAS SENSÍVEIS A DISTÚRBIOS / STUDY OF PENDULAR ACTIVE SYSTEMS FOR THE TRANSPORT IN VEHICLES OF LOADS SENSIBLE OF DISTURBANCES
Cranes are very used mechanical devices to load and to unload objects and/or to carry them in industries and warehouses. The movement of the crane is controlled by an operator or is programmed and controlled automatically. In the two cases, the movement of the crane cause undesirable swings of the load and claw, leading to an idle time before the grasping an

9. Ajustes posturais em individuos neurologicamente normais e em portadores da Sindrome de Down na gangorra : efeito do treino
The purpose of this study was to investigate the postural adjustments and the effects of practice during balance on seesaw. Subjects. Six individuals with Down syndrome and six neurological normal individuals (NN) took part of this study. Methods. The individuals were trained to balance on one seesaw and were tested before and after practice on nine differen

10. Effect of vision and stance width on human body motion when standing: implications for afferent control of lateral sway.
1. Measurements of human upright body movements in three dimensions have been made on thirty-five male subjects attempting to stand still with various stance widths and with eyes closed or open. Body motion was inferred from movements of eight markers fixed to specific sites on the body from the shoulders to the ankles. Motion of these markers was recorded t
