Three-dimensional Prussian blue-reduced graphene oxide hydrogel was synthesized with the assistance of sodium dodecyl sulfate (SDS) through a facile hydrothermal method. The hydrogel exhibited strong mechanical properties and was successfully applied as a self-propelling motor for water treatment. During the self-propelling degradation process, SDS facilitated the rapid liberation of oxygen bub...

This study was conducted in 2016 aimed to investigate the relationship between empowering leadership, uncertainty avoidance, trust, and employee creativity with regard to interaction effects and mediating mechanism. The population consists of 205 employees from the Nomadic affairs of Fars Province. In accordance with the Cochran formula, the sample size of 134 was calculated that were participa...

During mitosis, sister chromatids congress to the spindle equator and are subsequently segregated via attachment to dynamic kinetochore microtubule (kMT) plus ends. A major question is how kMT plus-end assembly is spatially regulated to achieve chromosome congression. Here we find in budding yeast that the widely conserved kinesin-5 sliding motor proteins, Cin8p and Kip1p, mediate chromosome co...

Hysteresis motor is self-starting synchronous motor that uses the hysteresis characteristics of magnetic materials to make torque. There are different methods to model this kind of motor and take into account the magnetic hysteresis characteristic of the rotor hysteresis ring. In this investigation the application of complex permeability concept is implemented to model the hysteresis loop and t...

The purpose of this study is to examine the reciprocal relationship between motor abilities and physical activity and the mediation effects of physical self-concept in this relationship using longitudinal data. We expect that the effects of motor abilities on physical activity are rather indirect via physical self-concept and that the effects of physical activity on motor abilities are rather d...

The so-called self-other correspondence problem in imitation demands to find the transformation that maps the motor dynamics of one partner to our own. This requires a general purpose sensorimotor mechanism that transforms an external fixation-point (partner's shoulder) reference frame to one's own body-centered reference frame. We propose that the mechanism of gain-modulation observed in parie...

Parallel pinch is an important grasp method. The end phalanx of the traditional parallel and self-adaptive gripper moves in arc trajectory, which requires auxiliary lifting motion industrial manipulator, inconvenient to use. To solve this problem, a novel robot finger designed implemented—Hoecken’s finger. In finger, Hoecken linkage mechanism used realize straight-line trajectory joint, differe...

This study examined the relationship between motor skill competence, and physical activity in 8–9 years-old girls (N=352). Locomotor and object control skill competence was assessed, using the Test of Gross Motor Development-2, and the Physical Activity Questionnaire for Children was used to assess physical activity. Regression analysis revealed that locomotor proficiency accounted for 20% (P...
