The complexity of the modern engineering systems besides the need for realistic considerations when modeling their availability and reliability render analytic methods very difficult to be used. Simulation methods, such as the Monte Carlo technique, which allow modeling the behavior of complex systems under realistic time-dependent operational conditions, are suitable tools to approach this pro...

The Gas to Gasoline (GTG) process includes conversion of natural, flare, and associated gas into synthetic fuels that can be compositionally upgraded and adjusted into different useful hydrocarbon fuels including gasoline, liquid petroleum gas (LPG), and fuel gas. Commonly, the GTG process involves three stages: 1) Synthesis gas (syngas) production unit 2) Methanol production unit 3) Methanol t...

In the course of studies dealing with metabolic effects of ethylenephosphoramide chemotherapy upon host and tumor tissues (2, 3, 14, 15), certain cytopathogenic effects were noted in sections of treated Walker 256 rat tumors. The changes con sisted of the appearance of large, polymorphic giant cells with bizarre nuclear and cytoplasmic configurations and unusual staining properties. Changes sim...
