Complex actions may arise by combining simple motor primitives. Our studies support individual premotor drive pulses or bursts as execution primitives in spinal cord. Alternatively, the fundamental execution primitives at the segmental level could be time-varying synergies. To distinguish these hypotheses, we examined sensory feedback effects during targeted wiping organized in spinal cord. Thi...

Although axial ultrasonic vibration-assisted milling (AUVAM) is promising for rapid and economical fabrication of 3D micro-texture on various surfaces, it has been a challenge to obtain with small feature size large height simultaneously. The mechanism major influence factors the formation by this method were explored in study. It was found that generation mainly caused cutting extrusion from f...

Monitoring the condition of spindle units modern metal-cutting machines by methods non-selective diagnostics involves possibility installing monitoring sensors in places with maximum vibration information. In this regard, assessment informative value field unit, which can be carried out advance, taking into account design features, geometric and dimensional characteristics, is an urgent task. B...

STUDY DESIGN A two-group experimental design with repeated measures on one factor was used. OBJECTIVES To investigate the role of paraspinal muscle spindles in lumbosacral position sense in individuals with and without low back pain. SUMMARY OF BACKGROUND DATA Proprioceptive deficits have been identified in patients with low back pain. The underlying mechanisms, however, are not well docume...

purpose: to assess the histopathological and immunohistochemical features of orbital spindle cell tumors. methods: a descriptive, retrospective study was performed on 63 pathology reports on all types of orbital spindle cell tumors at the pathology department of farabi hospital between 1995 and 2005. immunohistochemistry studies for different markers, such as smooth muscle actin, desmin, s100 p...

The hunt for environmentally friendly cutting fluids is underway as the problems of conventional become more evident. To achieve conscious machining, current study examines use Mango Kernel Seed Oil (MKSO) a fluid during turning AISI 1525 steel. According to 24 complete factorial techniques, vegetable-oil-based was produced by dissolving four different additives in mango kernel seed oil: emulsi...
