    The objective of this research was to evaluate the vegetative growth of yellow passion fruit seedlings, propagated by seeds, regarding the rates of use and application of two biostimulants in two types of soil. The experiment was carried out at the State University of Piauí (UESPI) / Campus de Corrente, with Passiflora edulis as a research culture, on a 50% brightness screen. The completely randomized design consisted of four treatments arranged according to the following application doses (0, 4, 8, 12 and 16 mL), using the biostimulant Solofull® and Stimulate® via soil, with six replicates per treatment, totaling 24 units experimental. The soil used came from two situations, soil 1 (area in the process of degradation, Gilbués - PI) and soil 2 (pasture area, Corrente, PI). At 65 days after sowing, height, stem diameter, number of true leaves, leaf area, plant height ratio and stem diameter and root length were evaluated. The data were submitted to analysis of variance. The application of the Stimulate® biostimulant in seedlings produced in soil cultivated by pasture, promoted the best development of the aerial and root system of the plants

    Towards Symbolic Model-Based Mutation Testing: Combining Reachability and Refinement Checking

    Full text link
    Model-based mutation testing uses altered test models to derive test cases that are able to reveal whether a modelled fault has been implemented. This requires conformance checking between the original and the mutated model. This paper presents an approach for symbolic conformance checking of action systems, which are well-suited to specify reactive systems. We also consider nondeterminism in our models. Hence, we do not check for equivalence, but for refinement. We encode the transition relation as well as the conformance relation as a constraint satisfaction problem and use a constraint solver in our reachability and refinement checking algorithms. Explicit conformance checking techniques often face state space explosion. First experimental evaluations show that our approach has potential to outperform explicit conformance checkers.Comment: In Proceedings MBT 2012, arXiv:1202.582

    Objetivo: Investigar a funcionalidade e o equilíbrio de idosos com e sem doença de Alzheimer (DA) submetidos a diversas bases de apoio e informações visuais, e analisar se as funções cognitivas impactam o equilíbrio de forma similar no idoso com e sem DA. Métodos: Vinte e seis idosos, sendo 10 com DA e 16 controles saudáveis participaram desse estudo. Os participantes foram submetidos a testes cognitivos gerais (Mini-Exame do Estado Mental) e específicos para funções cognitivas pré-frontais (Bateria de Avaliação Frontal, Teste do Desenho do Relógio e Teste de Fluência Verbal Semântica). A análise da funcionalidade ocorreu por meio do Índice de Pfeffer. Testes de equilíbrio foram realizados na plataforma de força, diante de bases de apoio de 30 e 10 cm, e informações visuais presentes e ausentes. A análise estatística envolveu os testes U-Mann Whitney, Friedman e índice de correlação de Spearman, sob significância de 5% (p<0,05). Resultados: Os resultados apontam que idosos com DA apresentam maior declínio cognitivo e funcional que idosos saudáveis. Os testes da plataforma de força indicaram semelhança do equilíbrio entre grupos, mas com impacto diferente das simulações de bases de apoio e informações visuais. Testes cognitivos pré-frontais mostraram associação significativa entre cognição e tarefas motores, sobretudo nas tarefas mais desafiadores.  Conclusão: O declínio funcional e cognitivo na DA tende a impactar o equilíbrio de forma diferente que em idosos saudáveis. Associação entre teste cognitivos pré-frontais e tarefas motores demonstra necessidade do fisioterapeuta abordar situações desafiadoras durante sessões de tratamento

    Objetivo: identificar  los diagnósticos de enfermería descriptos por la North American Nursing Diagnossis Association más frecuentes entre ancianos en situación de hospitalización; proponer prescripciones correlacionadas para el anciano en situación de hospitalización. Metodología: pesquisa cuantitativa, realizada con 50 ancianos hospitalizados en un hospital público del  Sur de Brasil. Los datos fueron analizados mediante estadística descriptiva. Resultados y discusión: los resultados demostraron que los diagnósticos de enfermería más frecuentes fueron: riesgo para infecciones; riesgo para la integridad de la piel perjudicada; riesgo para nutrición sin equilibrio: menor que las necesidades corporales; riesgo de caídas; Molde respiratorio ineficaz; troca de gases perjudicada; movilidad física perjudicada; exceso de volumen de líquidos; alteraciones en el molde de eliminación intestinal; alteraciones en el molde de eliminación urinaria; percepción sensorial perturbada: visión. a partir de los diagnósticos de enfermería identificados fue realizada una propuesta de prescripción de enfermería. Conclusiones: es esperado que el enfermero perciba la importancia de la realización del proceso de enfermería cómo parte fundamental del cuidado al anciano.Objetivo: identificar os diagnósticos de enfermagem descritos pela North American Nursing Diagnosis Association mais frequentes entre idosos em situação hospitalar; propor prescrições correlatas para idosos em situação hospitalar. Metodologia: pesquisa quantitativa, realizada com 50 idosos internados em um hospital público do Sul do Brasil. Os dados foram analisados mediante estatística descritiva.

    Background: We aimed to investigate the effect of rest interval, between successive contractions, on muscular fatigue. Methods: Eighteen subjects performed elbow flexion and extension (30 repetitions) on an isokinetic dynamometer with 80 degrees of range of motion. The flexion velocity was 120 degrees/s, while for elbow extension we used 5 different velocities (30, 75, 120, 240, 360 degrees/s), producing 5 different rest intervals (2.89, 1.28, 0.85, 0.57 and 0.54 s). Results: We observed that when the rest interval was 2.89 s there was a reduction in fatigue. On the other hand, when the rest interval was 0.54 s the fatigue was increased. Conclusions: When the resting time was lower (0.54 s) the decline of work in the flexor muscle group was higher compared with different rest interval duration.Universidade do Vale do ParaibaCAPE

    Abstract Background: Coactivation may be both desirable (injury prevention) or undesirable (strength measurement). In this context, different styles of muscle strength stimulus have being investigated. In this study we evaluated the effects of verbal and visual stimulation on rectus femoris and biceps femoris muscles contraction during isometric and concentric. Methods: We investigated 13 men (age =23.1 ± 3.8 years old; body mass =75.6 ± 9.1 kg; height =1.8 ± 0.07 m). We used the isokinetic dynamometer BIODEX device and an electromyographic (EMG) system. We evaluated the maximum isometric and isokinetic knee extension and flexion at 60°/s. The following conditions were evaluated: without visual nor verbal command (control); verbal command; visual command and; verbal and visual command. In relation to the concentric contraction, the volunteers performed five reciprocal and continuous contractions at 60°/s. With respect to isometric contractions it was made three contractions of five seconds for flexion and extension in a period of one minute. Results: We found that the peak torque during isometric flexion was higher in the subjects in the VVC condition (p > 0.05). In relation to muscle coactivation, the subjects presented higher values at the control condition (p > 0.05). \ud \ud \ud Conclusion\ud We suggest that this type of stimulus is effective for the lower limbs.This study received financial support from Universidade do Vale do Paraíba
