This study aimed to compare the effect of three stretching techniques (ballistic, static and contract-relax) on instant gain muscle flexibility on the hamstring muscle. We evaluated 23 subjects of both gender [means (SD) age 21.17 (1.4) years]. All volunteers performed static, ballistic and contract-relax stretching. Each technique was performed in a single session with an interval of seven days between sessions. To assess the immediate effects of the different techniques were performed two tests of flexibility, Sit and Reach Test and the Popliteal Angle Test. In comparison with the baseline there were significant increase in muscle flexibility in the Popliteal Angle Test after application ballistic (6.26%) and contract-relax technique (6.5%) respectively (p<0.05). When comparing the three techniques regarding the change score significant difference was found in the the Popliteal Angle Test for ballistic and contract-relax stretching, but Sit and Reach Test showed no significance difference. These data suggest that the ballistic and contract-relax were better than the technique of static stretching and both are equally effective. The ballistic contract-relax stretching techniques improved gain of muscle flexibility on the hamstring muscle.

OBJETIVOS: Verificar o medo de cair em idosas caidoras e não caidoras ativas fisicamente e comparar mobilidade e força de preensão palmar; verificar se existe relação entre mobilidade, força muscular e medo de quedas. MÉTODOS: Foram avaliadas 40 idosas ativas, idade ≥ 60 anos, divididas em caidoras (n = 20) e não caidoras (n = 20). Utilizou-se Mini-Exame do Estado Mental (MEEM) para rastreio cognitivo; Falls Efficacy Scale-International-Brasil (FES-I-BRASIL) para avaliar o medo de cair; a força muscular foi mensurada pela medida da força de preensão palmar por meio de dinamômetro hidráulico; Timed Up and Go (TUG) para avaliar mobilidade funcional. RESULTADOS: Não foi encontrada diferença significante entre os grupos no que diz respeito à mobilidade e força muscular. A maioria das participantes (92,5%) demonstrou preocupação com quedas. Das idosas que levaram mais que 12 segundos para desempenhar o TUG, 53,84% eram do grupo caidor. Não foi encontrada correlação entre mobilidade e força muscular. CONCLUSÃO: Não foi observada diferença significativa entre força muscular, mobilidade e medo de quedas entre os grupos. Não foi encontrada correlação significativa entre mobilidade, força muscular e medo de quedas. O estudo permitiu observar que o medo de cair está presente na maioria da população idosa, com ou sem história de quedas.

The knowledge of the mechanical properties of nickel-titanium (NiTi) termoactives of the more accessible of the domestic market is still limited. Given this, the objective of this study was to evaluate and compare through deflection tests in brackets NiTi wires 03 term rectangular gauge 0.014 '' enabled x 0.025 '' and 0.016 '' x 0.022 '' of different brands (MORELLI (R), ORMCO (R) ORTHOSOURCE (R), ORTHOMETRIC (R), EURODONTO (R) and ADITEK (R)). All tests were carried out on universal testing machine EMIC DL 2000 under identical conditions and controlled at a temperature of 36 degrees C +/- 0.5 degrees C. Five measurements (N= 5) were performed for each thickness/wire tag that was deflected up to a limit of 4.0mm at a speed of 1.0mm/min. Each 0.2mm (round trip) of corresponding strength measured deflection for the construction of the graph of force x deflection at Tesc program version 3.04. Each graphic was evaluated according to the following variables: beginning of the Martensitic transformation (cN and mm), maximum strength (cN), the beginning and end of the plateau of deactivation (cN and mm) and length (mm) plateau. The average and standard deviation were calculated for all variables and statistical analysis was made by ANOVA tests 2 criteria and Turkey or Kruskal-Wallis and Dunn, a 5% level of significance. The results showed that the tests of 0.014 '' x0.025 '' ORTHOMETRIC (R) brands and ORMCO (R) showed the best results, as well as the wires of the MORELLI (R) and ORTHOSOURCE (R) to wires 0.016 '' x0.022 ''. In General, the gauge wires 0.014 '' x0.025 '' showed strength levels on the plateau of deactivation to 6 x smaller than 0.016 '' x0.022 '' caliber.

To design connections between timber parts with metal dowels (nails or bolts), two phenomena must be considered: bending of the metal dowel and the embedment strength in the wood. The Brazilian Standard ABNT NBR 7190:1997 proposes the methods used in the laboratory tests to determine the embedment strength with the metal dowell and, in the absence of testing, specifies relations to calculate the embedment strength from the compression strength. The aim of this research was to compare the embedment strength values obtained by experimental tests and calculated by the relationships established by the Brazilian Standard ABNT NBR 7190:1997. By the results of the hypothesis tests, it was possible to conclude that the estimate of the embedment strength parallel to the grain proposed by the Brazilian standard ABNT NBR 7190:1997, establishing equivalence with the strength compression results in the same direction, must be effective to the wood species Pinus taeda L., however, the same was not found in the perpendicular direction with respect to the grain, possibly explained by the alpha(e) values in the equation to calculed fe(90)

The goal of this paper is to analyze the influence of the intense geomagnetic storms in the ionosphere and GNSS (GPS) positioning. It was analyzed the effects of intense geomagnetic storm of November 20th 2003 using GPS data from RBMC (Brazilian Network for Continuous Monitoring) located in different sites in the Brazilian region and ionosphere global maps. While analyzing the results, it can be observed an increase in the electron density of the ionosphere in the regions near to the geomagnetic equator in the afternoon on the day of the storm. In the period after the sunset of the storm day, there is an increase in the density of free electrons and ionospheric irregularities in regions furthest from the geomagnetic equator, when compared to geomagnetically quiet days. When the positioning point is analyzed, it is observed high discrepancies values in planimetry and altimetry at the same position for periods of changes that occurred in the ionosphere, especially for the GPS stations located furthest from the geomagnetic equator in the period after the sunset Sun.
