Gas-liquid mass transfer with parallel reversible reactions—I. Absorption of CO2 into solutions of sterically hindered amines [PDF]

open access: yes, 1989
A numerical method developed by Verteeg (1989, Chem. Engng Sci.44, 2295–2310; 1990, Chem Engng Sci.45, in press) is applied to some specific problems in gas—liquid mass transfer. The experimental results of Chakraborty (1986, Chem. Engng Sci.41, 997–1003)

Sequence variation and regulatory variation in acetylcholinesterase genes contribute to insecticide resistance in different populations of Leptinotarsa decemlineata

open access: yesEcology and Evolution, 2021
Although insect herbivores are known to evolve resistance to insecticides through multiple genetic mechanisms, resistance in individual species has been assumed to follow the same mechanism.

Carbon Dioxide and the Carbamate Post-Translational Modification

open access: yesFrontiers in Molecular Biosciences, 2022
Carbon dioxide is essential for life. It is at the beginning of every life process as a substrate of photosynthesis. It is at the end of every life process as the product of post-mortem decay.

Colour changes in pulses fumigated with different metal phosphide formulations

open access: yesJulius-Kühn-Archiv, 2018
Many phosphine-emitting products are used globally to control insect pests in dried vegetables, grains and pulses. However, variation in phosphide formulations is associated with colour change in many pulses. This study evaluated the effect of fumigation
