1. 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

3. Características biomecânicas de idosas caminhando em ambiente terrestre e aquático em piscina rasa e em piscina funda / Biomechanical characteristics of elderly women walking on land and in aquatic environment in shallow and deep water
Embora a prática de atividade física tenha se tornado comum em ambiente aquático, ainda há pouca informação a respeito das características biomecânicas da caminhada de idosos nesse ambiente. No intuito de investigar essas características, o objetivo do presente estudo foi comparar parâmetros cinemáticos (lineares e angulares) e eletromiográficos

4. Efeito seletivo da hemiplegia sobre a funÃÃo pulmonar e mobilidade diafragmÃtica
The cerebrovascular diseases is the second-most cause of death in Brazil and Latin America and is a refection of an economic and social lifestyle in the modern world. The Hemiplegia, common complication of stroke, is accompanied by hypertonic tonus in the affect side compromises the motor control of the entire body. Therefore the respiratory muscles compromi

5. DYNAMICS, KINEMATICS AND PHYSIOLOGICALS EFFECTS OF USING DIFFERENTS TYPES OS MAILBAGS / "Influência da mochila em parâmetros dinâmicos, cinemáticos e fisiológicos da locomoção de carteiros pedestres"
The aim of this study was to determine the influence of the satchel construction characteristics in selected biomechanical and physiological parameters during the accomplishment of the locomotion of mailmen pedestrians. 49 mailmen had been voluntary (30±7 years, 1.74±0.62 m and 72.6±11.8 kg), which had used 3 types of satchels, simple lateral satchel (MLS

6. Chaotic mixing deep in the lung
Our current understanding of the transport and deposition of aerosols (viruses, bacteria, air pollutants, aerosolized drugs) deep in the lung has been grounded in dispersive theories based on untested assumptions about the nature of acinar airflow fields. Traditionally, these have been taken to be simple and kinematically reversible. In this article, we appl

7. Galaxy dynamics and the mass density of the universe.
Dynamical evidence accumulated over the past 20 years has convinced astronomers that luminous matter in a spiral galaxy constitutes no more than 10% of the mass of a galaxy. An additional 90% is inferred by its gravitational effect on luminous material. Here I review recent observations concerning the distribution of luminous and nonluminous matter in the Mi

8. The effects of age and behavioral development on honey bee (Apis mellifera) flight performance
A critical but seldom-studied component of life history theory is how behavior and age affect whole-organism performance. To address this issue we compared the flight performance of honey bees (whose behavioral development and age can be assessed independently via simple manipulations of colony demographics) between distinct behavioral castes (in-hive nu
