Alcohol in the bloodstream modeled by differential equations

Does anyone know any good references which use partial differential equations to model the alcohol concentration in the bloodstream? I'm a mathematician, so I'm searching for a rigorous mathematical model. 


If you have any other suggestions of models in chemistry that uses partial differential equations, feel free to post them here.




One such article that I found was published by the University of South Florida. The abstract for which reads:



> 
> Given a set of differential equations describing blood alcohol content as a function time, we integrated the
>  equations to obtain a general solution. The general solution equation depends on three free parameters: the initial
>  concentration of alcohol in the stomach after ingestion, the rate of alcohol absorption into the blood stream and the rate
>  at which the alcohol is metabolized by the liver. We fitted our solution to experimental data to determine the unknown
>  parameters for a particular subject.
