Acyloin condensation reactions of pyruvic oxidase.

Almost all enzymes capable of decarboxylating pyruvate have been shown to catalyze DPT’-dependent condensation reactions yielding acyloins such as AMC (l-7). Recent work of Schweet and coworkers (8) has demonstrated that in animal tissues these condensations are due to the activity of pyruvic oxidase. Purified preparations of pyruvic oxidase from pigeon breast muscle have the same ratio of acyl...

Upgrading Drive-through Services of A

Discrete-process simulation, long used in the manufacturing sector of the economy for process analysis and improvement, has more recently, yet extensively, proved its value in the service industry for the same purposes. Very simple queuing situations are amenable to closed-form analysis; however, queuing environments typical of actual contexts in the service industry defy such analyses, except ...

Transition Metal Sulfide Catalysts for Petroleum Upgrading – Hydrodesulfurization Reactions

Maximal oil recovery by simultaneous condensation of alkane and steam.

This paper deals with the application of steam to enhance the recovery from petroleum reservoirs. We formulate a mathematical and numerical model that simulates coinjection of volatile oil with steam into a porous rock in a one-dimensional setting. We utilize the mathematical theory of conservation laws to validate the numerical simulations. This combined numerical and analytical approach revea...
