Petroleum-polluted soil samples from Ahvaz oilfield were enriched, using three methods to detect microorganisms with different dibenzothiophene degradation capabilities. Strain NISOC-03, a nitrate-reducing, oxidase negative, catalase, citrate, and urease positive, gram negative rod, showed interesting dibenzothiophene desulfurization behavior, designated as Entreobacter sp. strain NISOC-03 base...

We describe several line search strategies in recent potential reduction algorithms for linear programming. We clarify some concerns about the step size of the original algorithm. In particular, we illustrate that the dual step of the algorithm can be suuciently \long". We also discuss some other implementation issues for the algorithm.

Dezful embayment contains several potential source rocks deposited in tectonically active environments. Existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the Middle East. The Pabdeh Formation (Lower Paleocene-Eocene), the Gurpi Formation (Santonian-Masstrichtian), the Kazhdumi Formation (Albian) and the Gadvan Formation ...

This article deals with pollution control through source reduction, as an alternative to waste treatment. Many treatment systems simply remove an undesirable process waste from one medium and capture it in another. For example, scrubbers on smokestacks remove Undesirable combustion products by dissolving them in water. Biodegradation of chemicals in wastewater produces sludges (solid wastes)....

The report by the National Academy of Science Committee on Institutional Considerations in Reducing the Generation of Hazardous Industrial Waste examines key institutional, or nontechnical, factors that affect the generation of hazardous waste by industry. It provides a framework for evaluating public policies, both regulatory and nonregulatory, to reduce the generation of hazardous waste. The ...
