Empirical Correlations for K‐Values of Crude Oils

International Journal of Chemical Engineering, Volume 2022, Issue 1, 2022., 2022
Based on the Soave–Redlich–Kwong equation of state, empirical correlations for the K‐values of N2, CO2, H2S, C1, and C2 are proposed. Complementarily, the binary interaction coefficients involving the plus fraction, C7+, were optimized by fitting into 131 experimental data from the literature.

Polishing entire stems and roots using sandpaper under water: An alternative method for macroscopic analyses

Applications in Plant Sciences, Volume 9, Issue 5, May 2021., 2021
Premise Polishing entire stem and root samples is an effective method for studying their anatomy; however, polishing fresh samples to preserve woods with soft tissues or barks is challenging given that soft tissues shrink when dried. We propose sanding fresh or liquid‐preserved samples under water as an alternative, given that it preserves all tissues ...

An unusual overrepresentation of genetic factors related to iron homeostasis in the genome of the fluorescent Pseudomonas sp. ABC1

Microbial Biotechnology, Volume 14, Issue 3, Page 1060-1072, May 2021., 2021
‘Pseudomonas chilensis’ strain ABC1 was fully sequenced. About 5% of the ABC1 genome is devoted to iron acquisition, including 37 ECF sigma factors. Strain ABC1 produces pyoverdine and has the genes for the production of yersiniabactin. Summary Members of the genus Pseudomonas inhabit diverse environments, such as soil, water, plants and humans.
