Single fibre electromyography with axonal microstimulation was used to study the margin of safety of neuromuscular transmission in human and in rat muscle. The latter has been claimed to have a significantly wider safety margin compared to man. There is an inverse relationship between the jitter of the neuromuscular junction (NMJ) and its safety factor. Jitter was measured at 498 NMJs of the ex...

Abstract We build a system dynamics model based on conceptual originally proposed by safety scientist Jens Rasmussen to explore the of subject pressures for performance improvement. described forces that generate drift in boundary acceptable can push organization towards “flirting with margin” and thus operate at very high risk catastrophic failure. Simulations faithfully replicate behavior oth...

Basal cell carcinoma is a malignant epithelial neoplasm of the skin and most common human cancer. It generally associated with good prognosis. In this case report, giant basal nodulo-ulcerative type showing wide ulceration marginal multiple small nodules, presented. was trapezoidal in shape, having dimensions 7 cm at greatest width, 6 vertically different anterior posterior margin dimensions, 5...

this paper studies the effects of the structural variables of the iranian industries sector on the welfare cost using to the structure-conduct-performance (scp) theory. in other words, we investigate the role of structural components and their effects on the size of the welfare cost in iran's industry sector. we have used the leibenstein's model to calculate the deadweight loss and then the pan...
