1. Designing and fabrication of a low-cost dip-coater for rapid production of uniform thin films
In this work, a self-made dip-coater equipment was developed for the fabrication of thin films. The assembly of the apparatus was carried out using simple mechanical and electronic pieces, recycle parts, and spending an inexpensive budget suitably. The production, software design, and features of the device were focused on the sol-gel dip-coating method, whi

3. Age-related changes and effects of regular low-intensity exercise on gait, balance, and oxidative biomarkers in the spinal cord of Wistar rats
The present study aimed to analyze age-related changes to motor coordination, balance, spinal cord oxidative biomarkers in 3-, 6-, 18-, 24-, and 30-month-old rats. The effects of low-intensity exercise on these parameters were also analyzed in 6-, 18-, and 24-month-old rats. Body weight, blood glucose, total cholesterol, and high-density lipoprotein (HDL) ch

4. Application of methodology for the adequacy of the electrical motor's power sizing: permanent and transient analysis
Abstract The suitability of the motive force contributes to the efficient use of electrical energy. On the other hand, the inadequate size of electric motors is directly connected to increased investment and running costs. This article presents the theory and mainly the application of a methodology for the adequacy of the motive power. The research was condu

6. Spatiotemporal and variability gait data in community-dwelling elderly women from Brazil
ABSTRACT Background Gait is an extremely complex motor task; therefore, gait data should encompass as many gait parameters as possible. Objective To provide reference values for gait measurements obtained from a Brazilian group of community-dwelling elderly females between the ages of 65 and 89 years and to apply the PCA-biplot to yield insight into differ

7. Chemically Collapsible Mandrel for Solid Rocket Motor Processing
ABSTRACT: Composite propellant mainly consists of two parts, binder matrix (prepolymer, plasticizer, cross linker, antioxidant and curative etc.) and solid ingredients (oxidizer, metal fuel, burn rate modifier, combustion stabilizer etc.). Its processing involves several stages like ingredient preparation (grinding, 1.1 Hazard Division - 1.1 HD), mixing (1.1

8. Repercussão do uso da plataforma do Nintendo® Wii Fit™ plus no treinamento sensório-motor do freezing da marcha na doença de Parkinson
Gait disturbances are one of the main limiting factors for autonomy and quality of life in individuals with Parkinson’s disease (PD), and freezing of gait (FoG) is a common phenomenon that affects one-third of this population. Thus the effect of the implementation of a therapeutic program in a sensorimotor virtual environment through the Nintendo® Wii Fit

9. STEPPER MOTOR CONTROL APPLIED TO A ROBOTIC MANIPULATOR / CONTROLE DE MOTORES DE PASSO APLICADO A UM MANIPULADOR ROBÓTICO
Motores de passo são os motores mais utilizados em aplicações de controle de posicionamento em malha aberta. Entretanto, as limitações desta forma de atuação têm fomentado o desenvolvimento de novas técnicas que incorporem o controle em malha fechada. Motores de passo possuem boa relação entre torque e custo, tornando-os atraentes para aplicaçõe

11. Pharmacological and partial biochemical characterization of Bmaj-9 isolated from Bothrops marajoensis snake venom
Bmaj-9, a basic PLA2 (13679.33 Da), was isolated from Bothrops marajoensis snake venom through only one chromatographic step in reversed phase HPLC on ¼-Bondapak C-18 column. The amino acid composition showed that Bmaj-9 had a high content of Lys, His, and Arg, typical of a basic PLA2. The sequence of Bmaj-9 contains 124 amino acid residues with a pI value
