Determination of exposure to respirable quartz in the stone crushing units at Azendarian-West of Iran.
The purpose of this study is to describe the personal exposure to respirable dust and quartz and in stone crushing units located at west of Iran. A size of 40 personal samples and 40 stationary samples were obtained and analysis was done by X-ray diffraction (XRD). The results of personal sampling were shown the concentrations of respirable dust exposure level in workers of process, hopper and ...
متن کاملBurnt into memory - Psychological trauma
As you read this, 35 million humans in various parts of the world are fleeing from war. Their daily lives are severely affected by the psychological consequences of traumatic stress. Today’s military actions no longer resemble those of wars long ago, in which one country’s army fought the governmental forces of another. In today’s wars, more than 80% of casualties are civilians. A civilian’s ho...
متن کاملThe Heath - Jarrow - Morton Framework
The Heath-Jarrow-Morton framework refers to a class of models that are derived by directly modeling the dynamics of instantaneous forward-rates. The central insight of this framework is to recognize that there is an explicit relationship between the drift and volatility parameters of the forward-rate dynamics in a no-arbitrage world. The familiar short-rate models can be derived in the HJM fram...

متن کاملA"Burnt Bridge'' Brownian Ratchet
Motivated by a biased diffusion of molecular motors with the bias dependent on the state of the substrate, we investigate a random walk on a one-dimensional lattice that contains weak links (called " bridges ") which are affected by the walker. Namely, a bridge is destroyed with probability p when the walker crosses it; the walker is not allowed to cross it again and this leads to a directed mo...
