Sommario/riassunto

Fundamentals of Petroleum Refining provides a thorough and balanced introduction to refinery engineering topics, from basic concepts and unit operations to overall refinery economics, planning and control. Based on the fundamentals of thermodynamics and kinetics, the text develops the scientific background needed to understand refinery operations, provides an in-depth description of major refinery processes, and then assimilates an integrated refinery by focusing on the economic and operational aspects for enhancing performance and profitability.

Sommario/riassunto

The surface pigmentation of vertebrates is controlled by specialized cells able to synthesize a variety of pigments collectively known as melanins. Recent research has shown that melanins are produced not only in the skin but also in many other sites  such as the eye, inner ear, muscles, etc., -  where they are engaged in some unanticipated roles. The details of the synthetic pathway, the complexities of its regulation and biological significance that have been unravelled in recent research comprise a fascinating story and are of key importance in understanding the nature of diseases, includin
