The truth about population balance modeling

چکیده
Early researchers hoped to describe ball milling as a series of particle breakage and re-breakage events. This review reveals that needed input population balance modeling (PBM), the “breakage function,” was never intended be taken literally but assumed solve matrix calculations. Along with liquid-tracer–based residence time, rates each size class (the “selection function”) could then back-calculated, given measured mill feed product distributions. wet model, comprising function, solids time liquid, back-calculated rates, works quite well in circuit simulations. All three individual elements, however, are false. The model cannot used assess changes itself. While shrouded from proper vetting by complexity, lack progress industry eventually resulted discontinuation almost all PBM research. cumulative grinding provides practical replacement.

The truth about lying.
The standard view in social science and philosophy is that lying does not require the liar's assertion to be false, only that the liar believes it to be false. We conducted three experiments to test whether lying requires falsity. Overall, the results suggest that it does. We discuss some implications for social scientists working on social judgments, research on lie detection, and public moral...

Population balance modeling. Promise for the future
Population balance modeling has received an unprecedented amount of attention during the past few years from both academic and industrial quarters because of its applicability to a wide variety of particulate processes. In this article, a fresh look is taken of the basic issues of the application of population balances towards strengthening the approach as well as widening the scope of their ap...

During the period from 2001 to 2010 police officials in India were lured by a team of pseudo-scientists, from the Forensic Laboratories in Bangalore and Ahmadabad to make use of narcoanalysis, polygraph test and brain fingerprinting to extract confessions from accused persons. All the three tests, preceded by a pre-test interview and interrogation, were conducted by the one and the same expert ...
