This paper presents the results of continuing work on feedback control of unsupported standing in paraplegia. Our experimental setup considers a situation in which all joints above the ankle are braced, and stabilising torque at the ankle is generated by stimulation of the plantarflexors. A previous study showed that short periods of unsupported standing with paraplegic subjects could be achiev...

in a thousands beds general hospital affiliated to the tehran university, long-standing infestations of insects such as cockroaches, flies, mosquitoes and rat were found as a result of vicious circles and substandard clearing which are due to not well trained and drilled personnel of contracting agency, out of work condition of two incinerators, quasti-administrative aspects of their program on...

This study investigated the effectiveness of several possible exercises for performance during standing work in order to prevent lower leg swelling and relieve subjective complaints. Volume changes in the lower leg were measured using bioelectrical impedance plethysmography in 13 healthy male subjects aged 23-36 years. Subjective complaints of leg pain, leg dullness and whole body fatigue were ...

Mammalian spontaneous otoacoustic emissions (SOAEs) have been suggested to arise by three different mechanisms. The local-oscillator model, dating back to the work of Thomas Gold, supposes that SOAEs arise through the local, autonomous oscillation of some cellular constituent of the organ of Corti (e.g., the "active process" underlying the cochlear amplifier). Two other models, by contrast, bot...

In this work, our goal is to study the standing waves solutions to some generalization of the following system. { iφt + ∆φ = −div(|∇ψ|2∇ψ), ∆ψ = φ. We shall prove the existence of standing waves, solution to this equations and provide some stability results. ∗This work was partially supported by a grant from the Ministère de la Recherche et de la Technologie, France, Contrat no 90S0315. 1 ha l-...
