TLDR
In this article, the authors proposed a method to predict the distribution of residence-times in large systems by using distribution-functions for residencetimes, which can be used to calculate the etficiencies of reactors and blenders.About:

Dose‐dependency in local disposition of 5‐fluorouracil under non‐steady‐state condition in rat liver
TL;DR: The result suggests that the elimination activity by the hepatocytes in vitro may be lowered, compared with that in situ, according to the capacity-limited elimination in the hepatic local disposition of 5-FU.

Deactivation models by fitting the progression of temperature profiles – Coking model for the MTG process in adiabatic reactors
TL;DR: In this article, a methodology for estimating deactivation models for catalysts in industrial application is proposed, which applies the movement of the measured axial temperature profile to gain information of the deactivating phenomena.

TL;DR: An overall TSCB hydrodynamic identification was carried out by using residence time (RTD) and internal age (IAD) distribution studies and it was shown that each stage exhibited independent behaviour and could be modelled as a plug-flow reactor associated to j Continuous Stirred Tank Reactor, CSTR in series.

TL;DR: It was determined that water quality in the distribution network is characterized by turbidity and organic matter values higher than those evaluated in the plant effluent, and the plant needs several structural and managerial improvements.

A cellular automata model for liquid distribution in trickle bed reactors
TL;DR: In this paper, a cellular automata model for liquid distribution studies in trickle bed reactors is presented, which is a potential tool for describing non-uniform distribution of gas and liquid in a trickle bed.

The Definition and Measurement of Some Characteristics of Mixtures
TL;DR: In this paper, it is shown that the important features of such mixtures can be expressed by two statistically defined quantities, the scale and the intensity of segregation, and methods of measuring these are suggested.
