Anxiety can be distracting, disruptive, and incapacitating. Despite problems with empirical replication of this phenomenon, one fruitful avenue of study has emerged from working memory (WM) experiments where a translational method of anxiety induction (risk of shock) has been shown to disrupt spatial and verbal WM performance. Performance declines when resources (e.g., spatial attention, execut...

Conventional knee supporters generally reduce pain by restricting joint movement. In other words, there were no mechanical that functioned powerfully. Considering this problem, we first devised a device in which spring is inserted into the double structure of cylinder and piston, braking action applied to piston. This mechanism retracts when angle exceeds certain level. Next, modeled, dynamic c...

Flash-x-ray-diffraction patterns (FXD) with an exposure time of 4 ns of XaCl single crystals compressed bv plane shock waves are obtained a t pressures of about 30 kbar. From the diffraction patterns the compression is determined and compared with Hugoniot data. During shock load the lattice shows an uniaxial compression. While in case of measurements a t the free surface an observation time of...

Anaerobic digestion is a popular method for improving fertilizing properties, but there no report on the effect of shock load with butter anaerobic chicken manure. Therefore, this study aimed to investigate manure addition. The volatile suspended solid (VSS) was set at 20g VSS/L different additions from 0 60 g and oxygen flow rate (OFR) 2.5 mL/h. results showed that ammonia ranged 0.072 g/L 0.0...

There is strong experimental evidence for the existence of strange modes of failure of microelectromechanical systems (MEMS) devices under mechanical shock and impact. Such failures have not been explained with conventional models of MEMS. These failures are characterized by overlaps between moving microstructures and stationary electrodes, which cause electrical shorts. This work presents mode...

abstract in the recent decades, the iranian economy has been highly depended on oil revenues. considering the fact that a great part of non-oil exports are agricultures product, studying factors influencing growth of agricultural sector plays an important role in the iran's economy. supply domestic shocks and domestic demand pressure along with deviation of exchange rates from its equilibrium, ...
