Robot force control implemented by means of passive mechanical devices has inherent advantages over active implementations with regard to stability, response rapidity, and physical robustness. The class of devices considered in this paper consists of a Stewart platform-type mechanism interconnected with a network of adjustable mechanical elements such as springs and dampers. The control law rep...

Objectives: Specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. This study compared the passive comprehension as one of Syntactic Structures in Persian-speaking typically developing children and Specific language impaired children. Methods: 10 children w...

abstract background: motivation to academic achievement is critical for students of medical sciences, particularly nursing students. it is directly related to high levels of achievement and quality of life. accordingly, diminished motivation would result in academic decline, study and work desertion and exhaustion. therefore, this study aimed to investigate the effect of cognitive behavioural i...

In this study, the effect of molybdate on the electrochemical behavior and semi-conductive properties of duplex stainless steel 2205 passive film at NaCl solutions was investigated. Cyclic potentiodynamic polarization, impedance spectroscopy, mott-schottky plots and scanning electron microscopy (SEM) were used to study the passive behavior. Polarization curves showed that the corrosion current ...

OBJECTIVES To review the evidence for the application of tools for dengue outbreak prediction/detection and trend monitoring in passive and active disease surveillance systems in order to develop recommendations for endemic countries and identify important research needs. METHODS This systematic literature review followed the protocol of a review from 2008, extending the systematic search fro...

the history of five thousand years of human civilization (with only 292 years with no war) and the experiencesof the past two decades of our country shows that the enemies’ approach is based on strong air attack just inthe first month, and civilians bombarding begins if the spirit of national defense continues after two weeks.so the buildings in the cities are damaged in different ways by the a...
