The performance of the gutter brooms sweeping system was studied by conducting an experimental test. test is carried out operating a sweeper to sweep plastic, paper, and leaf waste. results show that at broom rotation speed 150,6 rpm, plastic obtained 100% success rate with three settings for height broom, while waste position ± 0 mm touching road surface paper 15 pressing surface. comprehensiv...

SUMMARY Grisel's syndrome is an unusual but important cause of torticollis which may be encountered in a pediatric plastic surgery practice, where craniofacial and oropharyngeal surgeries are commonly performed. Grisel's syndrome is characterized by painful torticollis and limited cervical rotation, and the diagnosis is confirmed via radiologic imaging. Initial management of Grisel's syndrome i...

we studied Attenuation in Fiber Optics, used two type of Fibers (Plastic and glass) with length (0.5,5,20m) (1,20,100m) respectively wavelength laser (660nm, 850nm), found attenuation increase 850nm 660nm are the best for plastic fiber optics, addition which occur from axial gap, axes rotation, inclination angle, transversal displacement investigated. Influence three values linear dispersion on...

The deformation and recrystallization mechanisms which control the viscoplasticity of ice from polar ice sheets have been investigated. The high plastic anisotropy of ice crystals is responsible for the development of a non uniform internal stress field within the polycrystal. Strain-shadows produced by sub-grain are observed in polarized light when the rotation recrystallization regime is domi...

OBJECTIVE To evaluate the effects of heel-opened ankle foot orthosis (HOAFO) on hemiparetic gait after stroke, especially on external foot rotation, and to compare the effects of HOAFO with conventional plastic-AFO (pAFO) and barefoot during gait. METHODS This cross-over observational study involved 15 hemiparetic patients with external rotation of the affected foot. All subjects were able to...

A device for the controlled trimming of plastic specimen blocks for light and electron microscopy is described. Many advantages of previously reported instruments together with 1) a rack and pinion control of knife movement, and 2) a control of rotation of the specimen block at 90 degrees, 180 degrees, 270 degrees, or 360 degrees are incorporated. In conjunction with an ocular micrometer, the d...

The seismic events that occurred in the last decades have highlighted importance of a correct design structures areas and inadequacy large part built heritage. Modern codes are still lacking terms prescriptions for evaluation performance existing buildings. present work proposes simplified method demand plastic rotation short links steel Eccentrically Braced Frames (EBFs). A relationship demand...
