Revisiting the Temkin Isotherm: Dimensional Inconsistency and Approximate Forms

نویسندگان

چکیده

The Temkin isotherm equation is increasingly being used to correlate adsorption isotherms of water contaminants. This research note shows that the as in environmental suffers from a fundamental flaw dimensional inconsistency. In addition, an important but frequently overlooked issue concerns approximate nature which limits its ability fit type I isotherms: it has neither Henry’s law limit at low loadings nor finite saturation high loadings. A different isotherm, approaches linear concentrations and commences (0,0) origin, shown outperform commonly terms fitting resembles Langmuir Freundlich describing data without plateau. It hoped material presented this will lead better comprehension isotherm.

Revisiting inconsistency in large pharmacogenomic studies

In 2013, we published a comparative analysis of mutation and gene expression profiles and drug sensitivity measurements for 15 drugs characterized in the 471 cancer cell lines screened in the Genomics of Drug Sensitivity in Cancer (GDSC) and Cancer Cell Line Encyclopedia (CCLE). While we found good concordance in gene expression profiles, there was substantial inconsistency in the drug response...

Trade-offs, Transitivity, and Temkin †

The last few years have seen a number of new and important publications in moral theory. Arguably none more important than Larry S. Temkin’s Rethinking the Good: Moral Ideals and the Nature of Practical Reasoning. This fascinating work highlights and explores in depth a seemingly fundamental inconsistency in our own axiological beliefs. Put roughly, the inconsistency arises given our general wi...

Revisiting Reuse for Approximate Query Processing

Visual data exploration tools allow users to quickly gather insights from new datasets. As dataset sizes continue to increase, though, new techniques will be necessary to maintain the interactivity guarantees that these tools require. Approximate query processing (AQP) attempts to tackle this problem and allows systems to return query results at “human speed.” However, existing AQP techniques s...
