Abstract: The use of Pilates-based exercises for trunk strengthening has been reported in the literature. The objective of this study was to analyze and compare the electrical activity of the rectus abdominis and external oblique muscles during a traditional abdominal exercise program and an exercise program based on the Pilates method using a ball and an elastic band. The sample was composed of 10 healthy women, non-practitioners of Pilates, who performed the traditional abdominal exercise and roll-up with the ball and elastic band. The sign was normalized by the electromyographic peak of the dynamics activity and was adjusted for 2000 samples/s; the filter was set in a frequency band from 20 to 450 Hz. In the comparison between exercises, the external oblique muscle in the concentric phase had a higher recruitment in the roll-up with the ball (P =0.042). In the comparison between muscles in each exercise, the rectus abdominis showed a higher activation in the concentric phase (P = 0.009) and in the eccentric phase (P = 0.05) of the traditional abdominal exercise. Activation percentages ranged from 15% to 22%. The traditional abdominal exercise had the largest activation percentage.

Abstract: Las preguntas que guían este trabajo son fundamentalmente dos: de qué manera los jóvenes uruguayos emigrados en Barcelona se han integrado en su nuevo país de destino? y cómo se vinculan con su país de origen viviendo fuera de fronteras? Las conclusiones generales, influidas por las teorías del multiculturalismo y el transnacionalismo, también son dos. El análisis sugiere que un número significativo de los inmigrantes uruguayos en Espa a tiende a desarrollar estrategias de integración en el país de acogida en paralelo con la recreación de su identidad uruguaya y su sentido de pertenencia al país de origen. Este proceso termina conformando una nueva ‘identidad guionada’ que permite que se construyan sólidos puentes de vinculación entre la nación uruguaya que vive afuera y adentro de fronteras. This paper will answer two questions: how young Uruguayan immigrants in Barcelona have integrated to their new country of destiny?, and how they relate to their country of origin living overseas? The general conclusions, influenced by the theories of transnationalism and multiculturalism, suggest that a significant number of Uruguayan immigrants in Barcelona develop integration strategies in their new country as they recreate in a parallel way their Uruguayan identity and their sense of belonging to the old homeland. In this process they conform a new hyphenated identity, which enables them to build solid bridges between the Uruguayan nation living inside and outside borders.

Abstract: Unconventional vegetables, in general, are plants that have been largely consumed by the population at some point and, because of changes in eating behavior, now present reduced economic and social expression and have lost ground to other vegetables. The objectives of this study were to perform phytochemical screening of the ethanol extracts of Rumex acetosa L., Tropaeolum majus L., Solanum muricatum, Stachys byzantina K. Koch and Solanum betaceum Cav. and evaluate their antioxidant potentials via the methods involving scavaging of the DPPH free radical and the ABTS radical, phosphomolybdenum and reducing power. In phytochemical screening, five species of unconventional vegetables tested positive for tannins; for sesquiterpene, lactones and other lactones. These tests were positive for Tropaeolum majus L. and Rumex acetosa L., Solanum betaceum Cav. and Solanum muricatum tested negative for steroids. Only Solanum betaceum Cav. gave positive tests for flavonoids. Among the five plant species studied, Stachys byzantina K. Koch presented the greatest antioxidant potential in all the methods evaluated.

Abstract: the present work evaluates the dry sliding wear performance of a 7075-t6 aluminum alloy autocatalytically coated with electroless ni-p. characteristics such as coating morphology, compositional variation of the coating through its thickness, as well as coating microhardness were reported. the wear tests were carried out in a tribometer, under ball-on-disc configuration, and balls of aisi 52100 steel of 6mm diameter were employed as a static counterpart. a normal load of 5n was applied for all the tests which were carried out at three different sliding velocities (0.005, 0.1 and 0.15 m/s) for 1000 m sliding distance. when the tests were conducted at low sliding velocity (0.05 m/s), a severe adhesive wear mechanism, characterized by plastic deformation and transference of the coating to the steel ball, was found for the aluminum alloy disc coated with electroless ni-p/aisi 52100 ball tribological pair. a three body abrasive wear mechanism was present when using higher sliding velocity. it was determined that, for the lowest sliding velocity employed in this study, the wear constant value for the coated system was 77% smaller than the value corresponding to the uncoated alloy. however, for all the tested conditions, the value of the wear constant was of approximately 10-4 mm3n-1m-1, indicating that both coated and uncoated aluminum alloy presented a low tribological performance under sliding conditions.
