Influence of the robotic exoskeleton Lokomat on the control of human gait : an ...
Barroso, Filipe; Santos, Cristina; Moreno, Juan C.Nowadays there is an increasing percentage of elderly people and it is expected that this percentage will continue increasing, carrying huge organizational costs in rehabilitation services. Recent robotic devices for gait training are more and more regarded as alternatives to solve cost-efficiency issues and provide novel approaches for training. Nevertheless, there is a need to address how to target muscular a...
Effects of robotic guidance on the coordination of locomotion
Moreno, Juan C.; Barroso, Filipe; Farina, Dario; Gizzi, Leonardo; Santos, Cristina; Molinari, Marco; Pons, José L.Functional integration of motor activity patterns enables the production of coordinated movements, such as walking. The activation of muscles by weightened summation of activation signals has been demonstrated to represent the spatiotemporal components that determine motor behavior during walking. Exoskeleton robotic devices are now often used in the rehabilitation practice to assist physical therapy of individ...
H3PW12O40 (HPA), an efficient and reusable catalyst for biodiesel production re...
Sepúlveda,Jorge H.; Vera,Carlos R.; Yori,Juan C.; Badano,Juan M.; Santarosa,Daniel; Mandelli,DalmoIn esterification of oleic acid with methanol at 25 °C HPA displayed the highest activity. Moreover the HPA could be reused after being transformed into its cesium salt. In the reaction of etherification of glycerol HPA and Amberlyst 35W showed similar initial activity levels. The results of acid properties demonstrate that HPA is a strong protonic acid and that both surface and bulk protons contribute to the a...
Efectos de metas academicas, autoeficacia y estrategias de aprendizaje en el re...
Barca-Lozano, Alfonso; Peralbo Uzquiano, Manuel; Almeida, Leandro S.; Brenlla Blanco, Juan C.; Vicente Castro, Florencio; Porto Rioboo, AnaObjetivo.

Muestra. Integrada por un total de 997 alumnos de 7º de Enseñanza Básica (Portugal) o de 1º de ESO (España). Del total de la muestra 510 eran del norte de Portugal (48% varones), de ...
Synthesis of liquid menthol by hydrogenation of dementholized peppermint oil ov...
Manuale,Debora L.; Betti,Carolina; Marchi,Alberto J.; Yori,Juan C.; Romeo,EvaHydrogenation of (-)-menthone and (+)-isomenthone was studied at 2.7 MPa and 100 ºC. The objective was to produce a liquid menthol mixture rich in (-)-menthol from dementholized peppermint oil. Ni-based catalysts were tested and compared for this reaction: a) 6 and 12% Ni dispersed into a nonstoichiometric magnesium aluminate (Ni-Mg-Al) with spinel structure; b) Ni-Raney catalyst. Both types of catalysts were a...
Poisoning and regeneration of Pt-Pd/WO3-ZrO2 short paraffin isomerization catal...
Canavese,Sergio; Finelli,Zunilda; Busto,Mariana; Benitez,Viviana M.; Vera,Carlos R.; Yori,Juan C.WO3-ZrO2 catalysts promoted with Pt and Pd were tested as paraffin isomerization catalysts using n-hexane as model compound. Sulfur and amine poisoning and regeneration tests were used to assess the impact of the addition of Pt and Pd on the deactivation resistance and regenerability. Pt and PtPd catalysts were the most active for n-hexane isomerization. The low activity of the Pd catalyst was attributed to poo...
Avaliação da atividade antibacteriana dos extratos de Avicennia schaueriana Sta...
Santos,Sidnei C. dos; Ferreira,Fábio S.; Damião,Alcinéia O.; Damião,Aldinéia O.; Barros,Tânia F.; Rossi-Alva,Juan C.; Fernandez,Luzimar GonzagaA flora tem sido uma fonte valiosa de constituintes bioativos para manutenção da saúde humana. Tal fato tem reforçado a crescente investigação do potencial terapêutico das plantas medicinais. Neste contexto, o presente trabalho teve como objetivo avaliar o potencial antibacteriano dos extratos hidro-alcoólicos da casca, folha, e raiz de Avicennia schaueriana Stapf & Leechm. ex Moldenke, Verbenaceae. As part...
Rapid assessment methods of resilience for natural and agricultural systems
Torrico,Juan C.; Janssens,Marc J.J.The resilience, ecological function and quality of both agricultural and natural systems were evaluated in the mountainous region of the Atlantic Rain Forest of Rio de Janeiro through Rapid Assessment Methods. For this goal new indicators were proposed, such as eco-volume, eco-height, bio-volume, volume efficiency, and resilience index. The following agricultural and natural systems have been compared according...
Genetic structure of Aedes aegypti in the city of Córdoba (Argentina), a recent...
Julio,Norma B; Chiappero,Marina B; Rossi,Hernán J; Rondan Dueñas,Juan C; Gardenal,Cristina NTo understand the transmission of a vector-borne disease, knowledge of the magnitude of dispersal among vector populations is essential because of its influence on pathogen transfer. The principal vector of dengue, the most common arboviral disease in the world, is the mosquito Aedes aegypti (L.). This tropical and subtropical species is native to Africa but has dispersed worldwide since the XV century. In Arge...
Exploitation of agro industrial wastes as immobilization carrier for solid-stat...
Orzua, María C.; Mussatto, Solange I.; Contreras-Esquivel, Juan C.; Rodriguez, Raul; Garza, Heliodoro de la; Teixeira, J. A.Ten agro industrial wastes were assessed for their suitability as fungus immobilization carrier for solid-state fermentation (SSF). The wastes included creosote bush leaves (Larrea tridentata), variegated Caribbean agave (Agave lechuguilla), lemon peel (Citrus aurantifolia), orange peel (Citrus sinensis), apple pomace (Malus domestica), pistachio shell (Pistacia vera), wheat bran (Triticum spp.), coconut husk (...
