INTRODUCTION This study aimed to determine the prevalence of Dupuytren's disease in men and its relationship with work exposure, particularly heavy manual work with and without significant use of vibrating tools, using data from a surveillance program for musculoskeletal disorders. METHOD This cross-sectional study was conducted in France between 2002 and 2005. Dupuytren's disease was diagnos...

conclusions it was concluded that the efficacy of tramadol and fluoxetine in males with premature ejaculation are the same and both are effective. both of these drugs are safe to treat premature ejaculation. results thirty-six subjects with the mean age of 44 ± 19.3 years underwent analysis. eighteen subjects were treated by fluoxetine and 18 by tramadol. the efficacy of treatment in the two gr...

This paper presents a new approach for the use of piezoelectric materials, PVDF and PZT, for vibration attenuation of a planar parallel manipulator. Since lightweight linkages of parallel manipulators deform under high acceleration/deceleration, such motion induced vibration would have to be damped quickly to reduce settling time of the platform position. An active damping controller is develop...

This paper puts forward a robust change detection procedure able to analyze the transient seismic motion and the vibration structure response, as well as to determine the changes in the amplitude and frequency content of the structure. This technique makes use of an impulse invariant transformation that will enable us to obtain an equivalent model of the vibration structure, represented by a pa...

DC bias will cause abnormal vibration of transformers. Aiming at such a problem, transformer vibration affected by DC bias has been studied combined with transformer core and winding vibration mechanism use multi-physical field simulation software COMSOL in this paper. Furthermore the coupling model of electromagnetic-structural force field has been established, and the variation pattern of inn...

In recent years, improvement has been achieved in vibration signal processing, using wavelet analysis for condition monitoring and fault diagnosis. The use of wavelet analysis has proven to be efficient to detect faults in vibration signals with nonstationary, transient characteristics/ components. An experimental data set is used to compare the diagnostic capability of the fast Fourier transfo...

Contrary to the common perception that termites are indiscriminant eaters, termites choose their food carefully; however, the methods by which they choose food are not well understood. Using choice experiments and recordings of termites feeding on wooden blocks of different sizes, we show that worker drywood termites (Cryptotermes domesticus) use the resonant frequency of a block of wood to ass...
